[0004] In related technologies, inkjet printing devices can spray ink onto printing materials such as paper, film, and cloth to accurately form the desired images or text on the printing materials, enabling high-definition printing operations and are widely used in various industries.

[0005] However, after the pattern is printed, the inkjet printer cannot automatically cut the printing material according to the size of the printed pattern. Usually, the printing material needs to be cut manually after printing to achieve the required size, which is quite inconvenient. Summary of the Invention

[0006] The main objective of this application is to propose an inkjet printing device.

[0007] The inkjet printing apparatus proposed in this application includes a print table, a print head, an ink supply module, and a cutter module. The print head is movably disposed above the print table for printing on printing material disposed on the print table. The ink supply module is connected to the print head for supplying ink to the print head. The cutter module is movably disposed above the print table for cutting the printing material on the print table.

[0008] In one embodiment, the cutter module is disposed on the print head.

[0009] In one embodiment, the print head includes a housing and a printing module. A receiving cavity is formed within the housing. A first passage and a second passage, communicating with the receiving cavity, are provided on the surface of the housing facing the print station. The first passage and the second passage are spaced apart. The printing module is disposed within the receiving cavity and is positioned opposite to the first passage. A cutter module is disposed within the receiving cavity and is positioned opposite to the second passage.

[0010] In one embodiment, the cutter module is movably disposed within the receiving cavity, and the cutter module has an extended state in which it extends at least partially out of the second passage, and a retracted state in which it retracts into the second passage.

[0011] In one embodiment, the cutter module can be rotatably positioned toward or away from the second passage. Alternatively, the cutter module can be translated toward or away from the second passage.

[0012] In one embodiment, the inkjet printing device further includes a housing with a receiving space formed therein, in which the print table, the print head, and the cutter module are disposed; the ink supply module is disposed in the receiving space and located behind the print head.

[0013] In one embodiment, the housing has a second opening, which is disposed opposite to the ink supply module. The housing includes a second cover plate, which can open or close the second opening.

[0014] In one embodiment, the inkjet printing apparatus further includes an ink stack module disposed within the receiving space and on the movement path of the print head, wherein the print head has a trimming state in which it moves above the ink stack module.

[0015] In one embodiment, the ink stack module has a cleaning surface, and the ink stack module includes a trigger structure disposed on the cleaning surface for detecting and positioning the print head.

[0016] In one embodiment, the inkjet printing apparatus further includes a reflective structure disposed within the receiving space and on the movement path of the print head, the print head having a first observation state of moving above the reflective structure; the reflective structure is also disposed on the movement path of the cutter module, the cutter module having a second observation state of moving above the reflective structure.

[0017] In one embodiment, the inkjet printing device further includes a negative pressure module, the printing station has an adsorption chamber, the surface of the printing station has a vacuum hole communicating with the adsorption chamber, and the negative pressure module is disposed in the adsorption chamber.

[0018] In one embodiment, the printing station is provided with a material detection mechanism, and the printing station is provided with a detection slot, with the material detection mechanism disposed in the detection slot.

[0019] In one embodiment, the inkjet printing apparatus further includes a moving device, the moving device including a second support frame and a driving mechanism, the print head being connected to the driving mechanism and movable relative to the second support frame, the driving mechanism being used to drive the print head to reciprocate along a first direction; and / or, the inkjet printing apparatus further includes a feeding mechanism, the feeding mechanism being disposed on one side of the printing table or the printing table, being used to drive the printing material to move along a second direction, the second direction intersecting the first direction.

[0020] The technical solution of this application sets a cutting module above the printing table, which can be used to cut the printing material on the printing table. After the print head performs the printing operation on the printing material, the cutting module can be used to directly cut the printing material of the required size, so as to achieve one-time printing on the inkjet printing device. There is no need to manually cut the printing material after printing output, which effectively improves the printing convenience and practicality of the inkjet printing device.

[0058] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0059] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0060] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0061] In related technologies, inkjet printers can spray ink onto printing materials such as paper, film, and fabric to accurately form the desired images or text, achieving high-definition printing and are widely used in various industries. However, after the pattern is printed, inkjet printers cannot automatically cut the printing material according to the size of the printed pattern. Usually, the printing material needs to be manually cut to the required size after printing, which is inconvenient.

[0062] To address the aforementioned problems and solve the issue of inkjet printers being unable to adjust the size of the printed material after printing, this application proposes an inkjet printer 1000. It should be noted that the inkjet printer proposed in this application can be a thermal inkjet printer, a piezoelectric inkjet printer, a white ink heat transfer printer (“Direct to Film”, DTF printer), a white ink direct-to-garment printer (“Direct to Garment”, DTG printer), etc., as long as it is a device used for inkjet printing operations. The printing material processed by the inkjet printer in this application can be paper, film, or even fabric, etc. This application does not limit the material and shape of the printing material, as long as it can be printed in the inkjet printer.

[0063] Please refer to Figures 1 to 5. In one embodiment of this application, the inkjet printing device 1000 includes a print table 200, a print head 100, an ink supply module 300, and a cutter module 15. The print head 100 is movably disposed above the print table 200 and is used to print the printing material disposed on the print table 200. The ink supply module 300 is connected to the print head 100 and is used to supply ink to the print head 100. The cutter module 15 is movably disposed above the print table 200 and is used to cut the printing material on the print table 200.

[0064] The printing table 200 forms a supporting structure for the entire machine's operation and processing, enabling the print head 100 to stably print on the printing material supported on the printing table 200, thus ensuring the stable operation of the inkjet printing device 1000. The printing table 200 can be of a regular shape, such as a cuboid or frustum, or it can be of an irregular shape; this application does not limit the specific shape of the printing table 200. The printing table 200 can be used to support the printing material.

[0065] The printhead 100 can integrate ink nozzles, control components, etc., enabling precise spraying of ink supplied by the ink supply module 300 onto the printing material. The principle of the printhead 100 spraying ink for printing is existing technology; therefore, the structure of the printhead 100 is not limited. The printhead 100 can be movable above the print table 200, either by using a track transmission device or by using a robotic arm or similar device. This application does not limit the method of movement of the printhead 100, as long as it can move on the print table 200. This allows the printhead 100 to perform printing operations according to a specific movement path, enabling it to better spray ink onto the printing material to form the desired image or text.

[0066] The ink supply module 300 can be connected to the print head 100 through a pipe to deliver ink, or the ink supply module 300 can be set in the print head 100 to directly deliver ink to the print head inside the print head 100. Of course, the ink supply module 300 can also supply ink to the print head 100 in other ways, as long as it can ensure that the ink is stably delivered to the print head 100 for inkjet printing. This application does not limit this.

[0067] By movably setting the cutter module 15 above the printing table 200, the printing material placed on the printing table 200 can be cut using the cutter module 15, thereby adjusting the size of the printing material. This facilitates direct cutting of the printing material during the printing process, enabling the inkjet printing device 1000 to directly output the processed printing material of the required size, thus achieving a more convenient and reliable printing process for the inkjet printing device 1000. The cutter module 15 can be mounted on the print head 100, and its movement is synchronized with the movement of the print head 100. The cutter module 15 can be positioned inside the print head 100 or around the print head 100. Alternatively, besides using the print head 100 to move the cutter module 15 synchronously, the cutter module 15 can be connected to the print head 100 using a combination of slide rails and sliders, allowing the cutter module 15 to move relative to the print head 100 to cut the printed material. Alternatively, the cutter module 15 can be mounted above the print table 200 using a lifting and lowering mechanism, allowing it to cut the printed material using a lifting and pressing method. Therefore, there are various ways to install the cutter module 15 and cut the printed material, and this application does not limit these methods.

[0068] The technical solution of this application provides a cutting module 15 above the print station 200. The cutting module 15 can be used to cut the printing material on the print station 200. After the print head 100 prints the material, the cutting module 15 can directly cut the printing material to the required size, so that the printing material can be printed in one go on the inkjet printing device 1000 without manually cutting the printing material after printing. This effectively improves the printing convenience and practicality of the inkjet printing device 1000.

[0069] Please refer to Figures 1 to 4. In some embodiments of this application, the inkjet printing device 1000 further includes a housing 700, which forms a receiving space. The printing table 200, the print head 100, and the cutter module 15 are disposed in the receiving space.

[0070] It is understandable that by placing the print table 200, print head 100, and cutter module 15 within the housing space, the printing process of the inkjet printing device 1000 can be carried out in a certain enclosed environment. This facilitates the use of the housing 700 to provide a certain degree of isolation and protection, effectively reducing the interference of environmental debris on the printing process and ensuring stable operation of the printing process. The housing 700 can be a single, integrated structure, or it can be formed by splicing multiple outer shells. This application does not limit the shape of the housing 700.

[0071] In some embodiments, the inkjet printing device 1000 can also house the ink supply module 300 within the receiving space, achieving a more functionally integrated structural design. In this case, the ink supply module 300 can be positioned behind the printhead 100 to avoid interference with the printhead 100's printing operations on the print table 200. This allows for a more rational layout of the various components of the inkjet printing device 1000 within the receiving space, facilitating a compact overall design and further improving the practicality and reliability of the inkjet printing device 1000. For ease of understanding and explanation, the directions indicated by the coordinate system shown in Figure 16 are used as references throughout this application. The first direction is the positive x-axis, and the second direction is the positive y-axis; the positive x-axis is right, and the negative x-axis is left; the positive y-axis is forward, and the negative y-axis is backward; the positive z-axis is upward, and the negative z-axis is downward.

[0072] Please refer to Figure 1. In some embodiments of this application, the housing 700 is provided with a first opening 71a that communicates with the receiving space. The first opening 71a is located above the printing table 200. The housing 700 also includes a first cover plate 71b, which can open or close the first opening 71a.

[0073] In this application, by providing a first opening 71a above the print stage 200 in the housing 700, the operating status of the print head 100, print stage 200, or other components within the housing space can be observed through the first opening 71a. This facilitates timely intervention, repair, or replacement of faulty components, ensuring the stable operation of the inkjet printing device 1000. The first opening 71a can be of a regular shape, such as a rectangle or a circle, or it can be of an irregular shape. This application does not limit the shape of the first opening 71a.

[0074] By setting the first cover plate 71b to open or close the first opening 71a, the first cover plate 71b can be connected to the housing 700. For example, the first cover plate 71b can be rotatably connected to the housing 700 to open or close the first opening 71a, or the first cover plate 71b can be slidably connected to the housing 700 to open or close the first opening 71a. Of course, the first cover plate 71b and the housing 700 can also be set separately. When it is necessary to open the first opening 71a, the first cover plate 71b can be removed from the housing 700, and when it is necessary to close the first opening 71a, the first cover plate 71b can be closed on the housing 700. Therefore, there are multiple ways to connect the first cover plate 71b and the housing 700, and this application does not limit this one. The first cover plate 71b can be made of a material with a certain degree of light transmittance, such as glass or acrylic, which facilitates observation of the operation of components within the receiving space even when the first cover plate 71b closes the first opening 71a. Alternatively, the first cover plate 71b can be made of high-strength steel; this application does not limit the material of the first cover plate 71b. In some embodiments, the first cover plate 71b can be of a regular shape, such as square or circular; however, it can also be of an irregular shape; this application does not limit the shape of the first cover plate 71b. The first cover plate 71b can be transparent or semi-transparent, allowing direct observation of the printing process inside.

[0075] In some embodiments, the housing 700 may be equipped with an opening / closing detection device for detecting the opening / closing state of the first cover plate 71b. It is understood that the opening / closing detection device may have two trigger states. When the first cover plate 71b closes the first opening 71a, one trigger state of the opening / closing detection device may be triggered. When the first cover plate 71b opens the first opening 71a, another trigger state of the opening / closing detection device may be triggered. This allows for the execution of certain system controls based on the state changes of the opening / closing detection device. For example, when the opening / closing detection device detects that the first cover plate 71b has opened the first opening 71a, the components in the receiving space may be put into a suspended operation state to facilitate component maintenance. Alternatively, the printing operation may only be started when the opening / closing detection device detects that the first cover plate 71b has closed the first opening 71a. Similarly, the opening / closing detection device may also be linked with other control systems, which is not limited in this application. There are many types of opening and closing detection devices. For example, a limit switch can be used, so that when the first cover plate 71b closes the first opening 71a, it contacts the trigger part of the limit switch, and when the first cover plate 71b opens the first opening 71a, it moves away from the trigger part of the limit switch. Alternatively, a Hall sensor can be used, in which case a magnet can be set on the first cover plate 71b, so that when the first cover plate 71b closes the first opening 71a, the magnet is brought close to the Hall sensor, and when the first cover plate 71b opens the first opening 71a, the magnet is moved away from the Hall sensor. This application does not limit the opening and closing detection device.

[0076] Please refer to Figure 2. In some embodiments of this application, when the ink supply module 300 is disposed within the receiving space, the housing 700 may be provided with a second opening 72a communicating with the receiving space. The second opening 72a may be located above the ink supply module 300 or behind the ink supply module 300. This application does not limit the position of the second opening 72a, as long as the ink supply module 300 can be exposed through the second opening 72a.

[0077] The second opening 72a can be of a regular shape, such as a rectangle or a circle, or of an irregular shape. This application does not limit the shape of the second opening 72a. Furthermore, through the second opening 72a, operations such as ink filling, maintenance, and pipe clearing of the ink supply module 300 can be performed to ensure the stable operation of the inkjet printing device 1000. The housing 700 may also include a second cover plate 72b, which can open or close the second opening 72a. The second cover plate 72b may be connected to the housing 700, for example, by sliding the second cover plate 72b on the housing 700 to open or close the second opening 72a, or by rotating the second cover plate 72b on the housing 700 to open or close the second opening 72a. Of course, the second cover plate 72b may also not be connected to the housing 700, that is, the second cover plate 72b and the housing 700 are separately set. When it is necessary to close the second opening 72a, the second cover plate 72b is placed on the housing 700, and when it is necessary to open the second opening 72a, the second cover plate 72b is removed from the housing 700. There are many ways to connect the second cover plate 72b and the housing 700, and this application does not limit this.

[0078] For example, the second cover plate 72b is provided with a first magnetic element, and the housing 700 is provided with a second magnetic element around the second opening 72a. The second cover plate 72b and the housing 700 are magnetically connected. The first magnetic element can be a magnet with a certain magnetic properties, and the second magnetic element can be a magnet with the opposite magnetic properties to the first magnetic element or a magnetically attractable metal element, etc.; or, the second magnetic element can be a magnet with a certain magnetic properties, and the first magnetic element can be a magnet with the opposite magnetic properties to the first magnetic element or a magnetically attractable metal element, etc. As long as the first magnetic element and the second magnetic element can achieve mutual magnetic attraction, this application does not limit this. By making the second cover plate 72b magnetically connected to the housing 700, the second cover plate 72b can be opened and closed on the housing 700 more conveniently, further improving the operational convenience of the inkjet printing device 1000.

[0079] Referring to Figure 3, in some embodiments of this application, when the inkjet printing device 1000 is equipped with an ink stack module 400 and a waste liquid container 500, and the waste liquid container 500 is located within a receiving space, the housing 700 can have a third opening 73a connected to the receiving space on one side adjacent to the waste liquid container 500. This allows the waste liquid container 500 to be exposed through the third opening 73a, facilitating easier assembly and disassembly of the waste liquid container 500 and further improving the operational convenience of the inkjet printing device 1000. The third opening 73a can be of a regular shape, such as a rectangle or a circle, or of an irregular shape. This application does not limit the shape of the third opening 73a.

[0080] In some embodiments, the housing 700 may be provided with a third cover plate 73b for closing or opening the third opening 73a, to ensure the integrity and aesthetics of the machine body, and to facilitate the installation and removal of the waste liquid box 500 from the housing 700. The third cover plate 73b may be connected to the housing 700, for example, by sliding the third cover plate 73b onto the housing 700 to open or close the third opening 73a, or by rotating the third cover plate 73b onto the housing 700 to open or close the third opening 73a. Alternatively, the third cover plate 73b may not be connected to the housing 700, meaning it is separate from the housing 700. When it is necessary to close the third opening 73a, the third cover plate 73b is placed on the housing 700; when it is necessary to open the third opening 73a, the third cover plate 73b is detached from the housing 700. There are many ways to connect the third cover plate 73b to the housing 700, and this application does not limit this.

[0081] Furthermore, the ink stack module 400 can be housed within the receiving space and positioned along the movement path of the print head 100. This ink stack module 400 can be used to clean the printing module 13 of the print head 100, preventing clogging or contamination of the inkjet outlet of the printing module 13. When the print head 100 is performing a printing job for a certain period or is in standby mode, it can be adjusted to a trimming state, allowing it to move above the ink stack module 400 for cleaning or docking. This facilitates better subsequent printing operations and further improves the practicality and reliability of the inkjet printing device 1000. For example, referring to Figures 4 and 16, when the printhead 100 can reciprocate along the first direction to perform a printing job, the ink stack module 400 can be arranged with the print stage 200 in the first direction. That is, the ink stack module 400 can be located on the left or right side of the print stage 200 to facilitate the movement of the printhead 100 between the ink stack module 400 and the print stage 200, thus achieving a more compact structural design of the inkjet printing device 1000. Of course, the ink stack module 400 and the print stage 200 can also be arranged in other ways within the receiving space, as long as they can be coordinated with the movement of the printhead 100. This application does not limit this arrangement.

[0082] Referring to Figures 4 and 16, in some embodiments of this application, the inkjet printing apparatus 1000 further includes a reflective structure 74. The reflective structure 74 is positioned close to the print table 200, allowing observation of the operating status of the printing module 13 of the print head 100 or the sharpness of the cutter module 15, facilitating the inspection and maintenance of the printing module 13 and the cutter module 15. The reflective structure 74 can be a mirror or a metal component with a certain reflective effect; this application does not limit its application to this.

[0083] For example, the reflective structure 74 can be disposed on the moving path of the print head 100. In this case, the inkjet printing device 1000 can control the print head 100 to adjust to a first observation state so that the print head 100 can move stably above the reflective structure 74 to observe the operating status of the printing module 13. In some embodiments, the reflective structure 74 can also be disposed on the moving path of the cutter module 15. In this case, the inkjet printing device 1000 can control the cutter module 15 to adjust to a second observation state so that the cutter module 15 can move stably above the reflective structure 74 to observe the sharpness of the print. The movement paths of the print head 100 and the cutter module 15 can at least partially overlap. For example, the cutter module 15 can be positioned on the print head 100 and move synchronously, so that the reflective structure 74 can be positioned at a point where the movement paths of the cutter module 15 and the print head 100 overlap. Alternatively, the reflective structure 74 can be designed with a larger size so that it can be located on both a segment of the movement path of the print head 100 and a segment of the movement path of the cutter module 15. Of course, the reflective structure 74 can also be designed in other ways, as long as it can be positioned on both the movement path of the print head 100 and the movement path of the cutter module 15. This application does not limit this.

[0084] Furthermore, referring to Figures 16 and 17, when the printhead 100 and the cutter module 15 can reciprocate along the first direction, the reflective structure 74 can be arranged with the print station 200 in the first direction. That is, the reflective structure 74 can be located on the left or right side of the print station 200 to facilitate the movement of the printhead 100 and the cutter module 15 between the reflective structure 74 and the print station 200, thus achieving a more compact structural design of the inkjet printing device 1000. Of course, the reflective structure 74 and the print station 200 can also be arranged in other ways within the receiving space, as long as they can cooperate with the movement of the printhead 100 and the cutter module 15. This application does not limit this arrangement.

[0085] In some embodiments, the housing 700 may have a fourth opening connected to the receiving space at a position adjacent to the reflective structure 74, so that the reflective structure 74 can be clearly observed through the fourth opening to understand the operating status of the print head 100 and the cutter module 15, facilitating timely cleaning of the print module 13 or maintenance and replacement of the cutter module 15. The fourth opening may be of a regular shape, such as a rectangle or a circle, or of an irregular shape; this application does not limit the shape of the fourth opening.

[0086] In some embodiments, the housing 700 may be provided with a fourth cover plate for closing or opening a fourth opening to ensure the integrity and aesthetics of the machine body, while also facilitating observation of the print head 100 and cutter module 15 through the reflective structure 74. This fourth cover plate may be connected to the housing 700, for example, by sliding the fourth cover plate onto the housing 700 to open or close the fourth opening, or by rotating the fourth cover plate onto the housing 700 to open or close the fourth opening. Alternatively, the fourth cover plate may not be connected to the housing 700, meaning it is a separate component. When it is necessary to close the fourth opening, the fourth cover plate is placed on the housing 700; when it is necessary to open the fourth opening, the fourth cover plate is detached from the housing 700. There are many ways to connect the fourth cover plate to the housing 700, and this application does not limit this method.

[0087] Please refer to Figures 1 to 3. In some embodiments of this application, the housing 700 may also have a printing material inlet 75a and a printing material outlet 75b on opposite sides. The printing material inlet 75a and the printing material outlet 75b may be respectively positioned relative to the feeding and discharging sides of the printing table 200, so that printing material can be fed into the machine body through the printing material inlet 75a for printing processing, and output through the printing material outlet 75b. The printing material inlet 75a and the printing material outlet 75b may be in the form of a regular rectangle, ellipse, or other irregular shapes. The shapes of the printing material inlet 75a and the printing material outlet 75b are not limited in this application.

[0088] Please refer to Figure 1. In some embodiments of this application, the inkjet printing device 1000 may be provided with a display module 1001, which is beneficial for displaying at least part of the operating status of the inkjet printing device 1000 using the display module 1001, and at the same time facilitates more intuitive operation of the inkjet printing device 1000, thereby improving the practicality and reliability of the inkjet printing device 1000.

[0089] Please refer to Figures 5 to 9. The printhead 100 proposed in this application includes a housing 11, a printing module 13, and a cutter module 15. A receiving cavity is formed inside the housing 11. The housing 11 has a printing surface. A first through-hole 1111a and a second through-hole 1111b communicating with the receiving cavity are opened on the printing surface. The first through-hole 1111a and the second through-hole 1111b are spaced apart. The printing module 13 is disposed in the receiving cavity and is disposed opposite to the first through-hole 1111a, and is used for printing on the printing material. The cutter module 15 is disposed in the receiving cavity and is disposed opposite to the second through-hole 1111b, and is used for cutting the printing material.

[0090] The housing 11 may be a hollow box structure to form a cavity for housing the printing module 13 and the cutting module 15, thereby isolating and protecting the functional modules placed inside the housing 11 and improving the protection performance of the print head 100. In some embodiments, the housing 11 may be cuboid, cube, or other shapes.

[0091] In some embodiments, one side of the housing 11 is used to form a printing surface. A first through-hole 1111a is provided on the printing surface to allow the printing module 13 within the accommodating cavity to operate outwards and print a preset image or text onto the printing material. A second through-hole 1111b is also provided on the printing surface to allow the cutting module 15 within the accommodating cavity to operate outwards and cut the printing material on the printing table. The printing surface can be a plane formed on the bottom end of the housing 11 facing the printing table. The shape of the first through-hole 1111a or the second through-hole 1111b can be cuboid, cube, or other shapes, which are not limited here. In one embodiment, the shape of the first through-hole 1111a can be contoured to the printing module 13, and the shape of the second through-hole 1111b can be contoured to the cutting module 15, so that the housing 11 can be positioned and assembled with the printing module and the cutting module 15 respectively.

[0092] Please refer to Figures 5 to 10. In the embodiments of this application, the cutter module 15 includes a first drive mechanism 151 and a cutter assembly 153. The first drive mechanism 151 is disposed in the accommodating cavity. The cutter assembly 153 is drivenly connected to the first drive mechanism 151 so that the cutter assembly 153 has an extended state in which it at least partially extends out of the second passage 1111b, and a retracted state in which it retracts into the second passage 1111b.

[0093] It should be noted that the inkjet printing device includes a drive unit located outside the printhead 100, and the printhead 100 can be connected to the drive unit for transmission. During use, the printhead 100 can move relative to the printing material under the drive unit to move to the corresponding position on the printing material, and the printing module 13 or the cutter module 15 can respectively print and cut the printing material.

[0094] The printing module 13 can be entirely housed within the receiving cavity of the housing 11, or partially housed within the receiving cavity and partially housed outside the receiving cavity; this is not limited here. The cutter module 15 can be retractably configured relative to the second passage 1111b. During the printing process, the printing surface of the print head 100 and the printing material are vertically aligned, i.e., vertically aligned. The printing module 13 can perform inkjet printing on the printing material below it, while the cutter assembly 153 remains in the retracted state of the second passage 1111b to prevent the cutter 1533 from damaging the printing material during the printing process of the print head 100, thus affecting the processing effect of the print head 100.

[0095] After completing the printing process, the printing module 13 stops inkjet printing on the printing material, and at the same time, the cutter assembly 153 switches to an extended state with at least a partial extension of the second passage 1111b, so that the printed material can be cut through the part of the cutter assembly 153 that extends out of the second passage 1111b.

[0096] Please refer to Figures 10 and 11. In one embodiment of this application, the first drive mechanism 151 includes a rotating part 1511. One end of the rotating part 1511 is disposed opposite to the second passage 1111b and connected to the cutter assembly 153. It is used to rotate relative to the second passage 1111b to drive the cutter assembly 153 to rotate toward or away from the second passage 1111b.

[0097] The rotating part 1511 is a mechanism that provides power to the cutter assembly 153 to drive the cutter assembly 153 to rotate toward or away from the second through-hole 1111b. The rotating part 1511 can be powered by a purely mechanical drive or by an electric drive; for example, the rotating part 1511 can be, but is not limited to, an electrically driven structure such as a rotary motor. The specific choice can be made by those skilled in the art.

[0098] The rotating part 1511 can be directly connected to the cutter assembly 153 to drive the cutter assembly 153 to rotate relative to the second through-hole 1111b; the rotating part 1511 can also be indirectly connected to the cutter assembly 153 through a transmission structure to drive the cutter assembly 153 to rotate by driving the transmission structure to move.

[0099] Please refer to Figure 12. In another embodiment of this application, the first drive mechanism 151 includes a translation part 1513. One end of the translation part 1513 is disposed opposite to the second passage 1111b and connected to the cutter assembly 153. It is used to translate relative to the second passage 1111b to drive the cutter assembly 153 to move toward or away from the second passage 1111b.

[0100] The translation unit 1513 is a mechanism that provides power to the cutter assembly 153 to drive it to move linearly toward or away from the second passage 1111b. This translation unit 1513 can be powered by a purely mechanical drive or by an electric drive; for example, the translation unit can be, but is not limited to, an electric drive structure such as a linear motor or a linear module. The specific choice can be made by those skilled in the art.

[0101] The translation unit 1513 can be directly connected to the cutter assembly 153 to drive the cutter assembly 153 to translate towards or away from the second passage 1111b; the translation unit 1513 can also be indirectly connected to the cutter assembly 153 through a transmission structure to drive the cutter assembly 153 to translate by driving the transmission structure to move.

[0102] In some embodiments, the translation part 1513 may include a pushing member 1513a and a first elastic member 1513b. In some embodiments, the pushing member 1513a is movably disposed on one side of the cutter assembly 153 and has an extended position and a retracted position. When the pushing member 1513a is in the extended position, it abuts against the cutter 1533 to drive the cutter assembly 153 into the extended state. When the pushing member 1513a is in the extended position, it disengages from the cutter 1533. The first elastic member 1513b elastically connects the cutter assembly 153 and the pushing member 1513a and drives the cutter assembly 153 to return to the retracted state when the pushing member 1513a is in the retracted position.

[0103] The pusher 1513a can be configured as an electrically driven structure; or, the print head 100 is configured to have an ejection stroke that moves in the forward direction of the first direction and a reset stroke that moves in the reverse direction of the first direction. The pusher 1513a is configured to be movable in the first direction, and is used to abut against a block outside the print head 100 when the print head 100 completes the ejection stroke and move to the extended position, so as to drive at least a portion of the cutter assembly 153 to extend out of the second passage 1111b, or to abut against another block outside the print head 100 when the print head 100 completes the reset stroke and move to the retracted position, so as to drive the cutter assembly 153 to retract into the second passage 1111b.

[0104] Of course, the technical solution of this application is not limited to this. In some embodiments, the first driving mechanism 151 may include a variety of driving structures. The various driving structures can be used for the rotating part 1511 and the translation part in the foregoing embodiments, so that the cutter assembly 153 can rotate or translate relative to the second through-hole 1111b in a multi-axis direction under the drive of the first driving mechanism 151. In this way, the degree of freedom of movement of the cutter assembly 153 can be improved. The specific implementation can be set according to actual needs and is not limited here.

[0105] Please refer to Figure 11. In the embodiments of this application, the cutter assembly 153 includes a frame 1531 and a cutter 1533. One end of the frame 1531 is connected to the first drive mechanism 151 for transmission. The cutter 1533 is disposed at the end of the frame 1531 away from the first drive mechanism 151 and is detachably connected to the frame 1531.

[0106] The frame 1531 serves as a fixed structure for mounting the cutter 1533 and can be connected to the first drive mechanism 151 for transmission. This allows the cutter 1533 to extend and retract relative to the second opening 1111b under the drive of the first drive mechanism 151. Since the cutter 1533 is detachably connected to the frame 1531, and the cutter assembly 153 is positioned opposite the second opening 1111b, the user can assemble or detach the cutter 1533 from the frame 1531 via the second opening 1111b without removing the housing 11, thus improving the ease of assembly and disassembly of the cutter 1533.

[0107] In this embodiment, the frame 1531 may also be provided with a limiting groove 1531a, and a portion of the cutter 1533 can be inserted into the limiting groove 1531a. Thus, the limiting groove 1531a can limit the cutter 1533, thereby achieving quick positioning of the cutter 1533 and the frame 1531, and thereby improving the connection stability between the cutter 1533 and the frame 1531.

[0108] It should be noted that the cutter 1533 can be detachably connected to the frame 1531 via magnetic attraction, threaded connection, or other methods. In some embodiments, the cutter 1533 can also be installed to the frame 1531 via two or more detachable connection methods simultaneously. For example, based on the magnetic connection between the cutter 1533 and the frame 1531, a screw structure can be used to further lock the cutter 1533 to the frame 1531, thereby further improving the connection stability between the frame 1531 and the cutter 1533.

[0109] Referring to Figure 11, in an embodiment of this application, the cutter assembly 153 further includes a pressing member 1535. The pressing member 1535 is disposed at one end of the frame 1531 away from the first drive mechanism 151 and protrudes from the frame 1531, and is arranged side by side with the cutter 1533 for pressing the printing material. It is understood that when the cutter 1533 cuts the printing material, the pressing member 1535 can press the printing material from the side of the cutter 1533 through its outer peripheral surface to prevent the printing material from lifting and affecting the cutting effect of the printing material of the cutter assembly 153. The pressing member 1535 may be in the form of a wheel structure, with its central axis direction perpendicular to the cutting surface of the cutter 1533; of course, the pressing member 1535 may also be configured in other shapes, which are not limited here.

[0110] In this embodiment, the side wall of the frame 1531 may be provided with a surrounding structure 1531b. This surrounding structure 1531b is located at the end of the pressing member 1535 away from the second passage 1111b and surrounds the periphery of the pressing member 1535. In this way, the side wall of the surrounding structure 1531b can be matched with the outer peripheral surface of the pressing member 1535 to achieve quick positioning of the pressing member 1535 and the frame 1531, thereby improving the connection stability between the pressing member 1535 and the frame 1531. The frame 1531 and the pressing member 1535 can also be positioned and limited by other limiting structures, such as the matching of positioning holes and positioning protrusions, etc., which are not limited in this application.

[0111] In some embodiments, the pressure member 1535 can be detachably connected to the frame 1531 to facilitate maintenance or replacement of the pressure member 1535. In some embodiments, the pressure member 1535 can be detachably connected to the frame 1531 by magnetic attraction or by threaded connection, and no limitation is made here.

[0112] In one feasible embodiment, the cutter assembly 153 further includes a fastener, which can be a screw. The frame 1531 may have a screw hole, and the fastener can pass through the cutter 1533 and the pressure member 1535 sequentially to achieve a threaded connection with the frame 1531. That is, the cutter 1533 and the pressure member 1535 can be locked onto the frame 1531 using the same fastener. Alternatively, the cutter 1533 and the pressure member 1535 can be fixed to the frame 1531 using different fasteners, allowing for individual assembly and disassembly of either the cutter 1533 or the pressure member 1535 according to usage requirements.

[0113] Please refer to Figures 5 to 9. In one embodiment of this application, two first through-holes 1111a are provided at intervals on the printing surface. There are two printing modules 13, each printing module 13 is provided with one first through-hole 1111a. The cutter module 15 is provided between the two printing modules 13, or the cutter module 15 is provided on the side of one printing module 13 away from the other printing module 13.

[0114] In this embodiment, the inkjet printing device can be a white ink heat transfer printer, which typically uses DTF ink composed of four CMYK colors ("Cyan Magenta Yellow blacK", printing four colors) and white. Correspondingly, the print head 100 has two printing modules 13. One printing module 13 is a color ink printing module, used to realize the color ink printing function corresponding to the four CMYK colors; the other printing module 13 is a white ink printing module, used to realize the white ink printing function. During use, the print head 100 can first print a colored pattern or text on the printing material through one printing module 13, and then print a layer of white ink on the colored pattern through the other printing module 13. In this way, by printing white ink on the printing material, the colors of the printed colored pattern or text are made more vibrant.

[0115] In one embodiment, two printing modules 13 are spaced apart, and a cutting module 15 can be positioned between the two printing modules 13. During use, after the color ink printing module and the white ink printing module complete pattern printing in sequence, the cutting module 15 can switch from a retracted state to an extended state and move to a specific position relative to the printing material to cut the printing material.

[0116] In another embodiment, the two printing modules 13 can also be arranged closely together, and the cutting module 15 can be located on the side of one printing module 13 facing away from the other printing module 13. For example, the color ink printing module, the white ink printing module, and the cutting module 15 can be arranged sequentially along the printing material transport direction, that is, they can be arranged sequentially along the second direction. In this way, the printing material can be connected to the color ink printing module, the white ink printing module, and the cutting module 15 sequentially during the transport process to complete the color ink printing, white ink printing, and printing material segmentation steps in sequence. Furthermore, since the printing material needs to be transferred to a baking machine or curing machine after completing the printing and printing material segmentation steps for the subsequent printing material drying step, and the inkjet printing device and the baking machine or curing machine are generally connected sequentially along the printing material transport direction, the arrangement of the color ink printing module, the white ink printing module, and the cutting module 15 sequentially along the printing material transport direction also facilitates the transfer of the segmented printing material to the baking machine or curing machine.

[0117] Please refer to Figures 5 to 9. In the embodiments of this application, the housing 11 includes a main housing 111 and a connector 113. The main housing 111 has a receiving cavity and a printing surface is formed at one end of the main housing 111. One end of the connector 113 is located on the outer side wall of the main housing 111, and the other end extends in a direction away from the main housing 111 for connecting to an external driving device so as to drive the print head 100 to move under the drive of the driving device.

[0118] In this embodiment, the main housing 111 can be a single integrated structure, formed by integral injection molding or integral die casting; or, the main housing 111 can be divided into several housing components and assembled from several housing components.

[0119] Referring to Figure 9, in one feasible embodiment, the main housing 111 includes a bottom shell 1111 and a cover 1113. The bottom shell 1111 has a top-opening accommodating space for placing components such as the printing module and the cutter module 15. The bottom shell 1111 also has a printing surface formed at its bottom end, with a first through-hole 1111a and a second through-hole 1111b penetrating the bottom wall of the bottom shell 1111. The bottom shell 1111 can be cuboid, cube, or other shapes. The cover 1113 is positioned above the bottom shell 1111, covering the opening at the top of the bottom shell 1111, and together with the bottom shell 1111, forms an accommodating cavity. By providing the cover 1113 to cover the opening, the various functional modules placed inside the accommodating cavity can be isolated and protected.

[0120] The connector 113 has a plate-like structure, with one end connected to the outer wall of the main housing 111. Specifically, it can be fixedly connected to the outer wall of the bottom housing 1111 or to the outer side of the cover 1113. The other end protrudes to the side of the main housing 111. By connecting the connector 113 to an external driving device, the driving device can drive the connector 113 to move the print head 100 relative to the printing material, so that the print head 100 can process different positions of the printing material. In some embodiments, the connector 113 also has a bearing surface 1131 formed on its top, so that the connector 113 can both connect to the external driving device and support some components of the print head 100.

[0121] Please refer to Figures 6 and 7. In the embodiments of this application, the printhead 100 further includes a main board 17, which is disposed in the accommodating cavity and connected to the cavity wall on the side of the accommodating cavity facing the connector 113. The main housing 111 includes a heat dissipation part 1111c, which is located on the side of the main housing 111 facing the connector 113 and is disposed to avoid the connector 113. At least a portion of the main board 17 abuts against the heat dissipation part 1111c to dissipate heat through the heat dissipation part 1111c.

[0122] The main housing 111 may have a heat sink connected to its outer side wall to form a heat sink 1111c. The heat sink may be, but is not limited to, a heat sink fin. The main housing 111 may also have a plurality of arrayed protrusions on its side away from the motherboard 17, thereby forming a heat sink fin through the structure of the main housing 111 itself, thus forming the heat sink 1111c of the main housing 111.

[0123] In some embodiments, at least a portion of the connector 113 is flush with the height of the heat dissipation part 1111c. Furthermore, a clearance groove can be provided in the area corresponding to the heat dissipation part 1111c on the side of the connector 113 facing the main housing 111, with the heat dissipation part 1111c disposed within this clearance groove. This allows the heat dissipation part 1111c and the connector 113 to be arranged to avoid each other. Alternatively, the heat dissipation part 1111c and the connector 113 can also be staggered in the height direction to achieve mutual clearance between them; this is not limited to this embodiment.

[0124] In some embodiments, to improve heat dissipation, the main housing 111 is also provided with heat dissipation holes 1111d in the area corresponding to the motherboard 17. For example, referring to Figure 5, one or more heat dissipation holes 1111d can be provided on both sides of the main housing 111 corresponding to the motherboard 17. The heat dissipation holes 1111d communicate with the accommodating cavity inside the main housing 111 to ventilate and dissipate heat from the motherboard 17 and other components inside the accommodating cavity.

[0125] Please refer to Figures 5 to 9. In the embodiments of this application, the housing 11 further includes a mounting member 115. One end of the mounting member 115 is located on the side of the main housing 111 away from the connector 113, and the other end extends in the direction away from the main housing 111. The print head 100 also includes a camera module 18, which is mounted on the mounting member 115.

[0126] It is understandable that by setting a camera module 18 on the print head 100 to capture the printing path of the print head 100, it is possible to detect whether the printing path of the print head 100 is a straight line, and further calibrate the printing position of the print head 100 based on the detection results, thereby helping to ensure the printing quality of the print head 100.

[0127] In one embodiment of this application, the mounting member 115 and the connecting member 113 are respectively disposed on opposite sides of the main housing 111. The connecting member 113 is connected to an external drive device, which can be disposed inside the housing of the inkjet printer, for example, behind the printhead 100. The external drive device can drive the printhead 100 to translate along a direction perpendicular to the arrangement of the mounting member 115 and the connecting member 113. This arrangement can reduce the volume of the printhead 100 in the direction perpendicular to the arrangement of the mounting member 115 and the connecting member 113, so that the printhead 100 can have sufficient transfer space. Of course, this application is not limited to this. In other embodiments, the drive device can also be connected to the main housing 111 or the mounting member 115 to drive the printhead 100 to translate along a direction perpendicular to the arrangement of the mounting member 115 and the connecting member 113.

[0128] The mounting component 115 can be a hollow box structure with an internal cavity for accommodating the camera module 18. This cavity can communicate with the accommodating cavity of the main housing 111, and the outer wall of the mounting component 115 has a through hole connecting to the internal cavity, allowing the camera module 18 to take pictures and detect objects outwards through the through hole. Alternatively, the mounting component 115 can also be a plate structure for fixing the camera module 18, with the camera module 18 fixed to the bottom of the plate structure. The mounting component 115 can be separate from the main housing 111, or it can be integrated with the main housing 111, thereby improving the overall stability of the printhead 100 structure.

[0129] In the embodiments of this application, at least a portion of the main housing 111 is made of plastic material. It should be noted that in related technologies, the housing 11 of the printhead 100 is typically made of sheet metal. In contrast, the technical solution of this application, by making at least a portion of the main housing 111 of plastic material, helps to reduce the weight of the housing 11, facilitating the external drive device to drive the printhead 100 and allowing for greater flexibility in adjusting the speed of the printhead 100. Furthermore, the use of plastic material also helps to reduce the manufacturing cost of the housing 11.

[0130] In the embodiments of this application, the connector 113 is made of sheet metal. Since the printhead 100 is connected to the external drive device through the connector 113 of the housing 11 in the inkjet printing device, the overall weight of the printhead 100 is mainly supported by the connector 113. By setting the material of the connector 113 to sheet metal, the structural strength of the connector 113 can be guaranteed, thereby ensuring the structural stability of the inkjet printing device.

[0131] Referring to Figures 13 and 14, in some embodiments, the printing module 13 includes an inkjet mechanism 131, an ink storage mechanism 133, and a leak-proof mechanism (not shown). The inkjet mechanism 131 is located at the first port 1111a. The ink storage mechanism 133 is detachably connected to the inkjet mechanism 131 to supply ink to the inkjet mechanism 131. The leak-proof mechanism is connected between the inkjet mechanism 131 and the ink storage mechanism 133 to prevent ink leakage from the ink storage mechanism 133 when the ink storage mechanism 133 and the inkjet mechanism 131 are separated. The inkjet mechanism 131 is used to eject ink.

[0132] The ink storage mechanism 133 can be a color ink supply mechanism, such as a color ink cartridge, or a white ink supply mechanism, such as a white ink cartridge. The inkjet mechanism 131 can be configured as a printhead for printing the ink supplied by the ink cartridge onto the printing material using inkjet printing.

[0133] In one embodiment of this application, the ink storage mechanism 133 and the inkjet mechanism 131 can be connected by a plug-in connection, thus enabling quick plugging and unplugging of the ink storage mechanism 133 and the inkjet mechanism 131, improving the assembly convenience of the printing module 13. Of course, the ink storage mechanism 133 and the inkjet mechanism 131 can also be connected by a snap-fit ​​connection, a threaded connection, or other detachable methods, which are not limited here. In some embodiments, the ink storage mechanism 133 can be connected to the ink supply module 300 via a conduit, so that the ink supply module 300 can supply ink to the ink storage mechanism 133, and then the ink storage mechanism 133 sprays the ink onto the printing material through the inkjet mechanism 131.

[0134] It should be noted that in a printing module 13, multiple ink storage mechanisms 133 can be provided, and these multiple ink storage mechanisms 133 are connected side by side to the inkjet mechanism 131. To improve the connection stability between the ink storage mechanism 133 and the inkjet mechanism 131, the inkjet mechanism 131 can be provided with multiple positioning grooves 1311. The shape of the positioning grooves 1311 is set to conform to the shape of the inkjet mechanism 131, and each positioning groove 1311 is used to limit the engagement with an inkjet mechanism 131. Of course, the inkjet mechanism 131 can also limit the ink storage mechanism 133 through other positioning structures, which are not limited here.

[0135] The ink storage mechanism 133 is detachably connected to the inkjet mechanism 131. This means that after the ink storage mechanism 133 is installed on the inkjet mechanism 131, it can be separated and removed to facilitate maintenance and replacement of the various structures of the printing module 13. Furthermore, by connecting the leak-proof mechanism between the inkjet mechanism 131 and the ink storage mechanism 133, it is possible to prevent ink from leaking out of the ink storage mechanism 133 and directly entering the receiving cavity when the leak-proof mechanism is removed from the inkjet mechanism 131, thus avoiding contamination of other structures of the printhead 100.

[0136] The leak prevention mechanism can be configured as a leak prevention valve. When the ink storage mechanism 133 is connected to the inkjet mechanism 131, the leak prevention valve opens to connect the ink path of the ink storage mechanism 133 and the inkjet mechanism 131. When the ink storage mechanism 133 is disconnected from the inkjet mechanism 131, the leak prevention valve closes to stop the ink storage mechanism 133 from discharging ink.

[0137] In one feasible implementation, the inkjet printing device can be a white ink heat transfer printer. Correspondingly, in the two printing modules 13 of the printhead 100, one printing module 13 is provided with four ink storage mechanisms 133, configured as four color ink cartridges corresponding to the four CMYK colors; the other printing module 13 can also be provided with four ink storage mechanisms 133, all of which are white ink cartridges. During use, the printhead 100 can first print a color pattern on the printing material through one printing module 13, and then print a layer of white ink on the color pattern through the other printing module 13. In this way, by printing white ink on the printing material, the colors of the printed color pattern are made more vibrant.

[0138] In some embodiments, when all four ink storage mechanisms 133 in the printing module 13 are white ink cartridges, the four white ink cartridges can be designed as a single unit, that is, the four white ink cartridges are connected to form an integrated structure. In this way, the four white ink cartridges can be assembled and disassembled as a whole with the inkjet mechanism 131, which helps to improve the structural integration and ease of assembly and disassembly of the printing module 13.

[0139] Please refer to Figures 6 and 13. In some embodiments, the printing module 13 further includes an adapter board 134, which can be electrically connected to the inkjet mechanism 131. The input interface of the adapter board 134 can be connected to the motherboard 17. The adapter board 134 can connect to multiple printheads in the inkjet mechanism 131 (the four in Figure 13). Thus, when assembling the printing module 13, only one ribbon cable is needed to connect the motherboard 17 and the adapter board 134 together, instead of setting up multiple ribbon cables to connect the motherboard and multiple printheads. Wiring is more convenient and assembly is simpler.

[0140] Referring to Figures 6 and 7, in the embodiments of this application, the printhead 100 further includes an anti-collision mechanism 19, which is disposed on the housing 11 to prevent the housing 11 from being subjected to external impacts. It is understood that by providing the anti-collision mechanism 19 on the printhead 100 to prevent the housing 11 from being subjected to external impacts, the safety of the printhead 100 can be improved.

[0141] The anti-collision mechanism 19 can be disposed on the side of the housing 11 to prevent the outer wall of the print head 100 from colliding with external structures. For example, if the print head 100 can move along a first direction, the anti-collision mechanism 19 can be disposed on opposite sides of the print head 100 along the first direction, thereby avoiding the risk of the housing 11 being impacted by external forces when the print head 100 moves along the first direction. Alternatively, the anti-collision mechanism 19 can also be disposed on the bottom of the housing 11 to prevent the printing surface at the bottom of the print head 100 from colliding with external structures, thereby achieving an anti-pinch effect. Alternatively, anti-collision mechanisms 19 can be disposed on both the side and the bottom of the housing 11 to improve the comprehensive protection of the print head 100. Of course, the anti-collision mechanism 19 can also be used to achieve anti-collision functions at other locations on the housing 11. The number of anti-collision mechanisms 19 provided on the housing 11 can be one, two, or more. That is, this application does not limit the location or number of anti-collision mechanisms 19.

[0142] In some embodiments, anti-collision mechanisms 19 are provided on the sides and bottom of the housing 11. The anti-collision mechanisms 19 located on the sides and bottom of the housing 11 can be integrated into one unit. This helps to reduce the number of parts on the print head 100, thereby improving the structural integration and assembly efficiency of the print head 100.

[0143] In one embodiment, the anti-collision mechanism 19 may be disposed on the housing 11 of the printhead 100 and at least partially protrude from the outer surface of the housing 11. Thus, during the movement of the printhead 100, the anti-collision mechanism 19 can detect whether it is in contact with an external structure through contact detection. For example, the anti-collision mechanism 19 may be configured as a pressure sensor or other contact detection mechanism. Because the anti-collision mechanism 19 protrudes from the outer surface of the housing 11, it can contact the external structure before the housing 11, thereby braking the housing 11 in a timely manner when the anti-collision mechanism 19 is triggered, to avoid excessive movement of the housing 11 and collision with the external structure.

[0144] Alternatively, in another embodiment, the anti-collision mechanism 19 can also detect its distance to the external structure through non-contact detection. For example, the anti-collision mechanism 19 can be configured as an infrared ranging sensor or other non-contact detection mechanism. In this way, the housing 11 can be braked in time when it is detected that the distance between the anti-collision mechanism 19 and the external structure is too close, so as to avoid the housing 11 moving excessively and colliding with the external structure. The specific configuration can be set as needed and is not limited here.

[0145] Please refer to Figures 16 and 20. In some embodiments of this application, the inkjet printing device 1000 further includes a negative pressure module 29, an adsorption chamber 21 is provided in the printing table 200, and a vacuum hole 24 communicating with the adsorption chamber 21 is provided on the surface of the printing table 200. The negative pressure module 29 is disposed in the adsorption chamber 21.

[0146] In this embodiment, an adsorption cavity 21 with a certain space can be formed within the printing stage 200. The negative pressure module 29 operates within the adsorption cavity 21, creating a vacuum negative pressure environment. This allows the printing material placed on the surface of the printing stage 200 to be subjected to the negative pressure at the vacuum hole 24, ensuring stable adsorption of the printing material on the surface of the printing stage 200 for printing. This prevents the printing material from shifting during processing, reduces printing waste, and ensures accurate printing results from the inkjet printing device 1000. The negative pressure module 29 can employ various structures, such as axial flow fans or centrifugal fans. This application does not limit the type of negative pressure module 29, as long as it can extract air from the adsorption cavity 21 to create a negative pressure environment. In some embodiments, a single negative pressure module 29 can be provided within the adsorption cavity 21, or multiple negative pressure modules 29 can be arranged in a row within the adsorption cavity 21 to increase the rate of negative pressure environment formation. This application does not specifically limit the number of negative pressure modules 29.

[0147] In one embodiment, the adsorption chamber 21 can be flat, and the negative pressure module 29 can be configured as a centrifugal fan. It is understood that the smaller height of the centrifugal fan allows for easier placement within the flat adsorption chamber 21, which helps to reduce the height of the printing table 200, decrease the space occupied by the supporting components within the machine body, and achieve a better spatial layout of the various components within the inkjet printing device 1000.

[0148] Please refer to Figures 16 to 18. In some embodiments of this application, the printing table 200 has a feeding side and an output side. The inkjet printing device 1000 also includes a feeding mechanism 22, which is located on the feeding side of the printing table 200 or integrated into the printing table 200.

[0149] In this embodiment, printing material can be fed from the feed side of the printing station 200 to the surface of the printing station 200 for printing processing, and after the processing is completed on the printing station 200, it can be output from the discharge side of the printing station 200. By setting a feeding mechanism 22 on the feed side of the printing station 200, the feeding mechanism 22 can play a certain transmission role for the printing material, so that the printing material can move stably from the feed side to the discharge side, realizing the continuous automatic feeding operation of the inkjet printing device 1000. For ease of understanding and explanation, the directions indicated by the coordinate system shown in Figure 16 are used as references, where the first direction is the positive direction of the x-axis, the second direction is the positive direction of the y-axis; the positive direction of the x-axis is right, the negative direction of the x-axis is left; the positive direction of the y-axis is forward, the negative direction of the y-axis is backward; the positive direction of the z-axis is up, and the negative direction of the z-axis is down. The feeding side and the discharging side of the printing table 200 can be opposite sides along the second direction, so that the printing material can move under the transmission action of the feeding mechanism 22, that is, the printing material can be fed and printed along the first direction. At this time, the print head 100 can move along the second direction. Then, by adjusting the transmission efficiency of the feeding mechanism 22 and the moving speed of the print head 100, the precise printing operation of the print head 100 can be achieved.

[0150] In some embodiments, the feeding mechanism 22 may include a bracket fixedly mounted on the feeding side of the print station 200, a rotating shaft 221 rotatably mounted on the bracket, and a roller 223 sleeved on the rotating shaft 221. The rotating shaft 221 can be driven to rotate by a motor or other driving component. By driving the roller 223 to rotate using the rotating shaft 221, the roller 223 can come into contact with the printing material placed on the feeding side of the print station 200. The printing material can then be transmitted along a second direction under the frictional force between the roller 223 and the printing material, achieving stable feeding of the inkjet printing device 1000. Of course, this application is not limited to this. In other embodiments, the feeding mechanism 22 may also adopt a conveyor belt structure. This application does not limit the structural shape of the feeding mechanism 22, as long as it can achieve the transmission of printing material.

[0151] Referring to Figures 18 and 19, in some embodiments of this application, a limiting plate 25 extending in a second direction may be provided on the surface of the printing table 200. This limiting plate 25 is disposed opposite to the surface of the printing table 200 and forms a transfer groove 251 spaced apart from the printing table 200. The edge of the printing material is held within the transfer groove 251. It is understood that the limiting plate 25 can be bent and connected to the surface of the printing table 200 along its side in the first direction, or the limiting plate 25 can be formed by bending the side of the printing table 200 upwards, so that the limiting plate 25 and the printing table 200 are integrally formed. This application does not limit the shape of the limiting plate 25. By using the limiting plate 25 to form a conveying groove 251 on the printing table 200 at intervals, the edge of the printing material can be locked in the conveying groove 251 when the printing material is conveyed along the second direction. This allows the limiting plate 25 to play a certain limiting role in the conveying of the printing material, effectively preventing the printing material from deviating during the conveying process and potentially affecting the printing effect, thus achieving precise printing processing of the inkjet printing device 1000.

[0152] Please refer to Figure 17. In some embodiments of this application, the inkjet printing apparatus 1000 further includes a pressing mechanism 23, which is disposed above the printing table 200 and is used to press the printing material onto the surface of the printing table 200.

[0153] It is understandable that when the printing material is placed on the printing table 200, the pressing mechanism 23 can be used to press the printing material so that the printing material can better adhere to the surface of the printing table 200 for printing processing, thereby reducing the defect rate of the printed material after processing and further improving the reliability of the inkjet printing device 1000.

[0154] Referring to Figure 17, in some embodiments, the pressing mechanism 23 may include a second drive mechanism 231 and a pressure roller 233. The second drive mechanism 231 may include a first support frame 2311, a transmission rod 2313, and a handle 2315. The transmission rod 2313 may be a cam rod structure. By rotatably connecting the transmission rod 2313 to the first support frame 2311 and connecting the handle 2315 to one end of the transmission rod 2313, and using the pressure roller 233 sleeved on the transmission rod 2313, the handle 2315 can be operated on one side of the first support frame 2311 to drive the transmission rod 2313 to rotate, causing the cam surface on the transmission rod 2313 to abut against and drive the pressure roller 233 to move toward the printing table 200, so that the pressure roller 233 presses the printing material; while the pressure roller... The pressure roller 233 can be equipped with a second elastic element such as a spring or rubber pad. When the second drive mechanism 231 drives the pressure roller 233 to move downwards, the second elastic element in the pressure roller 233 can be in a certain elastic deformation state. Therefore, when it is necessary to release the pressure roller 233 from the printing material and remove or place the printing material, the handle 2315 can be operated in the opposite direction, causing the plane on the transmission rod 2313 to contact the pressure roller 233. At this time, the second elastic element in the pressure roller 233 is released from force and recovers its elastic deformation, allowing the pressure roller 233 to reset and move away from the printing table 200. This achieves stable pressure and avoidance of the printing material by the pressure roller 233 mechanism, ensuring stable printing and handling of the printing material on the printing table 200, and further improving the practicality and reliability of the inkjet printing device 1000. Of course, this application is not limited to this. In other embodiments, the pressure mechanism 23 can also adopt a lifting pressure block structure. This application does not limit the structure of the pressure mechanism 23, as long as it can achieve the pressing of the printing material on the printing table 200.

[0155] In the inkjet printing device 1000, when the feeding mechanism 22 is used to convey printing material, the pressing mechanism 23 can be located at least partially above the feeding mechanism 22 so that the pressing mechanism 23 can press the printing material onto the feeding mechanism 22, ensuring contact between the printing material and the feeding mechanism 22, and allowing the feeding mechanism 22 to more stably convey the printing material to the surface of the printing table 200.

[0156] Referring to Figures 18 and 19, in some embodiments of this application, a material detection mechanism 271 may be installed on the print station 200. This material detection mechanism 271 can detect the presence of printing material on the print station 200. The information detected by the material detection mechanism 271 can then be transmitted to the controller of the inkjet printer 1000. This allows the print head 100 to be started only after it is confirmed that printing material is placed on the print station 200, preventing the print head 100 from directly spraying ink onto the print station 200. Furthermore, by using the material detection mechanism 271 to detect the presence or absence of printing material on the print station 200, feedback can also be provided on whether the printing material has been successfully loaded, facilitating fault detection of the inkjet printer 1000 and further improving its practicality and reliability.

[0157] In some embodiments, please refer to Figures 21 and 22. A detection groove 27 may be provided on the printing table 200. The material detection mechanism 271 is housed in the detection groove 27 so that the material detection mechanism 271 can identify the printing material on the surface of the printing table 200 through the opening of the detection groove 27. This helps to reduce the interference between the material detection mechanism 271 and the printing material on the surface of the printing table 200, so that the printing material can be processed or transferred more smoothly on the printing table 200. At this time, the material detection mechanism 271 may include a signal transmitter and a signal receiver. The signal transmitter can be used to emit detection light such as infrared light. When no printing material is placed on the surface of the printing table 200, the detection light emitted by the signal transmitter is not blocked or reflected, so the signal receiver cannot receive the detection light emitted by the signal reflector. This allows the signal receiver to send a signal to the controller that no printing material has been placed. When printing material is placed on the surface of the printing table 200, the printing material covers the opening of the detection slot 27, so the detection light reflected by the signal reflector is blocked and reflected by the printing material. This allows the signal receiver to receive the light emitted by the signal transmitter, and the signal receiver sends a signal to the controller that printing material has been placed. Of course, this application is not limited to this. In other embodiments, the material detection mechanism 271 may also use a photosensitive sensor, a pressure-sensitive sensor, etc. This application does not limit the type of the material detection mechanism 271, as long as it can detect whether printing material is present on the printing table 200.

[0158] Please refer to Figures 4, 16 and 21. In some embodiments of this application, the inkjet printing apparatus 1000 includes a moving device 600, which is disposed above or on one side of the print table 200 and connected to the print head 100 for driving the print head 100 to move on the print table 200.

[0159] In some embodiments, please refer to Figures 21 to 23. In some embodiments, the moving device 600 includes a second support frame 61 and a drive mechanism 63. The second support frame 61 is disposed on the base of the housing 700. The drive mechanism 63 is connected to the second support frame 61. The print head 100 is connected to the drive mechanism 63 and can move relative to the second support frame 61. The drive mechanism 63 drives the print head 100 to reciprocate along a first direction.

[0160] For ease of understanding and explanation, the directions indicated by the coordinate system shown in Figure 16 are used as references. The first direction is the positive direction of the x-axis, and the second direction is the positive direction of the y-axis. The positive direction of the x-axis is right, and the negative direction is left; the positive direction of the y-axis is forward, and the negative direction is backward; the positive direction of the z-axis is up, and the negative direction is down. In this embodiment, the second support frame 61 can be formed from steel with a certain structural strength. Alternatively, it can be formed by overlapping tubular structures. The structural material and shape of the second support frame 61 can vary, as long as it provides sufficient support. This application does not limit its application in this regard. The drive mechanism 63 can be a synchronous belt drive (i.e., a combination of pulleys and belts) or a chain drive (i.e., a combination of sprockets and chains). This application does not limit the drive mechanism 63's transmission method, as long as it can drive the print head 100. Furthermore, the first direction can be the length direction of the second support frame 61, that is, the length direction of the machine body. The drive mechanism 63 drives the print head 100 to move back and forth along the first direction on the second support frame 61. The position of the print head 100 can be adjusted back and forth according to a certain movement path so that the print head 100 can spray ink on the printing material to form the required image or text.

[0161] In some embodiments, referring to Figure 21, the moving device 600 further includes a support rail 65 and a support slider 67. The support rail 65 is disposed on the second support frame 61 and extends along the first direction, and can be arranged side by side with the drive mechanism 63. The support slider 67 is movably connected to the support rail 65, and the print head 100 is connected to the support slider 67. By utilizing the movement of the support slider 67 along the first direction on the support rail 65, a certain degree of rigid support can be provided for the print head 100, which helps to distribute some of the force on the print head 100, reduce the load requirements of the drive mechanism 63, and better improve the service life of the drive mechanism 63.

[0162] In some embodiments, referring to Figures 21 and 23, the drive mechanism 63 includes a third drive mechanism, a driving wheel 633, a driven wheel 635, and a transmission belt 637. The driving wheel 633 and the driven wheel 635 are tractably mounted on the second support frame 61. The transmission belt 637 connects the driving wheel 633 and the driven wheel 635. The third drive mechanism is connected to the second support frame 61 and drives the driving wheel 633 to rotate, thereby causing the driving wheel 633 to drive the transmission belt 637 and the driven wheel 635 to rotate. The third drive mechanism can be a motor, or other devices that drive the driving wheel 633 to rotate; this application does not limit this. The transmission belt 637 includes a clamp 6371 and a belt body 6373. The clamp 6371 can be connected to the print head 100 so that the print head 100 can move along a first direction following the clamp 6371. The chuck 6371 includes a base plate 6371a and two opposing clamping blocks 6371b. A clamping groove is formed between the two opposing clamping blocks 6371b. The two ends of the belt body 6373 are respectively inserted into the clamping groove from opposite sides of the chuck 6371. The two opposing clamping blocks 6371b are movable relative to each other so that the chuck 6371 clamps the two ends of the belt body 6373, forming a ring shape with the chuck 6371. This ring-shaped transmission belt 637 formed by the chuck 6371 clamping the two ends of the belt body 6373 allows for easier adjustment of the overall length of the transmission belt 637, making it more adaptable to various types of drive mechanisms 63. The opposing surfaces of the two clamping blocks 6371b can be provided with protruding structures such as meshing teeth, allowing the chuck 6371 to better engage and clamp the belt body 6373, improving the structural stability and reliability of the transmission belt 637. For example, the clamping block 6371b can be connected to the base plate 6371a by screw connection. In this case, a shuttle-shaped structure can be provided on the side of the base plate 6371a adjacent to the clamping block 6371b, so that the clamping block 6371b can abut against the shuttle-shaped structure during the tightening and installation process, thereby bringing the two clamping blocks 6371b closer to each other to clamp the strap body 6373. Of course, the clamping block 6371b and the base plate 6371a can also be connected by means of snap-fit ​​or other means, as long as the connection of the clamping block 6371b on the base plate 6371a can be realized and the strap body 6373 can be clamped. This application does not limit this.

[0163] In some embodiments, referring to Figures 21 and 22, the drive mechanism 63 further includes a tensioning mechanism 639 for adjusting the distance between the driven wheel 635 and the driving wheel 633. For example, in some embodiments, the tensioning mechanism 639 may include an adjusting plate 6391, an adjusting bolt 6393, and a third elastic element 6395. The adjusting plate 6391 is connected to the second support frame 61 and is located on one side of the driven wheel 635. The adjusting plate 6391 is provided with bolt holes, the adjusting bolt 6393 is connected to the bolt holes, and the third elastic element 6395 is connected to the adjusting bolt 6393 and abuts against the driven wheel 635. The third elastic element 6395 may be a spring or rubber, etc. This application does not limit the type of the third elastic element 6395. By tightening or loosening the adjusting bolt 6393 on the adjusting plate 6391, the elastic deformation of the third elastic element 6395 can be changed, thereby adjusting the distance between the driven wheel 635 and the driving wheel 633, realizing the tension adjustment of the transmission belt 637, so that the drive mechanism 63 can drive the print head 100 to reciprocate along the first direction more stably. Of course, this application is not limited to this. In other embodiments, the tensioning mechanism 639 may also adopt a sliding structure that connects and supports the driven wheel 635. This application does not limit the tensioning mechanism 639, as long as it can realize the adjustment of the distance between the driven wheel 635 and the driving wheel 633.

[0164] Please refer to Figures 15 and 24. In some embodiments of this application, the ink supply module 300 includes an ink cartridge 31 and an ink supply line 33, which connects the ink cartridge 31 and the printing module 13 of the print head 100.

[0165] It is understandable that the ink cartridge 31 can be a storage container that can store a certain amount of ink. By using the ink supply line 33 to connect the ink cartridge 31 and the printing module 13 of the print head 100, the print head 100 and the ink supply module 300 can be better arranged through the pipeline layout, so that the inkjet printing device 1000 can achieve a more reasonable structural design.

[0166] Referring to Figures 15 and 24, the ink supply module 300 can be equipped with at least two ink cartridges 31. By injecting different colors of ink into the at least two ink cartridges 31, the print head 100 can achieve various inkjet effects using different ink combinations, thereby enabling the inkjet printing device 1000 to better process and form the desired images or text on the printing material. At this time, the at least two ink cartridges 31 can be arranged sequentially to form a whole, facilitating the assembly and disassembly of the ink cartridges 31. A sequentially engaging assembly and disassembly structure can be provided between the at least two ink cartridges 31, so that the at least two ink cartridges 31 can only be removed through a specific order of removal and placement. Alternatively, the ink supply module 300 can also use a mounting bracket to hold the at least two ink cartridges 31, allowing the ink cartridges 31 to be arranged on the bracket in a specific order. This application does not limit the assembly method of the ink cartridges 31. In some implementations, the ink supply module 300 may be provided with at least two ink supply lines 33, so that one ink supply line 33 is connected to one ink cartridge 31, ensuring stable and independent ink supply to multiple ink cartridges 31 and ensuring the stable operation of the inkjet printer 1000.

[0167] It is understandable that the ink supply module 300 can place the ink cartridge 31 outside the inkjet printer 1000, and connect the ink cartridge 31 and the printhead 100 through an ink supply pipe for ink supply; alternatively, if the inkjet printer 1000 has a housing 700 to accommodate multiple components, the ink supply module 300 can also be placed within the housing 700's accommodating space, allowing the inkjet printer 1000 to integrate multiple components within the housing 700, thus improving the aesthetics and compact design of the inkjet printer 1000. Of course, this application does not limit the placement of the ink supply module 300, as long as it achieves stable placement of the ink supply module 300 and ensures the supply of ink to the printhead 100.

[0168] For example, referring to Figure 15, in some embodiments, when the ink supply module 300 is disposed within the housing 700, a third support frame 76 can be provided behind the printhead 100 in the housing 700, allowing the ink cartridges 31 of the ink supply module 300 to be stably arranged and mounted on the third support frame 76. Furthermore, the ink supply pipeline 33 is stably routed within the housing 700 to achieve a stable connection and ink supply between the ink cartridges 31 and the printhead 100. The ink supply pipeline 33 can be sequentially connected to a filter 331 and a pump 333. The pump 333 generates a suction force in the ink supply pipeline 33, allowing the ink to pass sequentially through the filter 331 and the pump 333 before flowing into the printing module 13 of the printhead 100. This helps reduce impurities in the ink that could clog the printing module 13, ensuring stable printing by the printing module 13. The filter 331 and pump 333 can be installed inside the housing 700, and multiple pipe sections are used to sequentially connect the ink cartridge 31, filter 331, pump 333 and printing module 13 to achieve a more compact structural layout of the inkjet printing device 1000.

[0169] In some embodiments, referring to Figure 26, the ink cartridge 31 may be equipped with an ink detection device 311. This device 311 can detect the amount of ink within the cartridge 31. For example, the ink detection device 311 may include a first detection float 3111 disposed within the cartridge 31 and a first detection signal 3113 disposed outside the cartridge 31. The first detection float 3111 can move with the ink level in the cartridge 31, and when it reaches a certain height, it can trigger the first detection signal 3113, causing the first detection signal 3113 to send a signal to the controller of the inkjet printer 1000 indicating insufficient ink or full ink, reminding the user to add ink to the cartridge 31 or stop adding ink. The first detection signal 3113 can be a Hall sensor, and the first detection float 3111 may contain a trigger structure 47 such as a magnet, so that when the first detection float 3111 rises or falls to a position opposite to the first detection signal 3113, it can trigger the first detection signal 3113. Of course, the ink detection device 311 can also use a pressure-sensitive sensor or other detection device, and this application does not limit it.

[0170] In addition, the ink cartridge 31 may also be provided with a guide structure 319 for guiding and limiting the lifting and lowering movement of the first detection float 3111, so that the first detection float 3111 can be vertically lifted and lowered in a third direction to prevent the first detection float 3111 from leaving the detection range of the first detection signal 3113.

[0171] Referring to Figure 25, in some embodiments, ink cartridge 31 may include a first ink cartridge 313 and a second ink cartridge 315. The first ink cartridge 313 is equipped with a stirring mechanism 35. When the inkjet printer 1000 prints on printing materials such as film, it is common practice to spray colored ink first and then spray white ink as the base color of the printing material. In this case, the first ink cartridge 313 can be used to store white ink, and the second ink cartridge 315 can be used to store colored ink. Of course, this application is not limited to this. In other embodiments, the first ink cartridge 313 and the second ink cartridge 315 can also be used to store other different types of ink to ensure the printing function of the inkjet printer 1000. When the first ink cartridge 313 is filled with inks such as white ink that are prone to condensation, the stirring mechanism 35 can be used to stir the ink in the first ink cartridge 313, which can effectively prevent the ink in the first ink cartridge 313 from condensing and ensure the fluidity of the ink in the first ink cartridge 313.

[0172] In some embodiments, referring to Figure 25, the stirring mechanism 35 includes a stirring blade 351 and a stirring motor 353. The stirring blade 351 is rotatably disposed within the first ink cartridge 313, and the stirring motor 353 is disposed on the outer wall of the first ink cartridge 313. The rotating shaft 221 of the stirring motor 353 passes through the wall of the first ink cartridge 313 and connects to the stirring blade 351. By using the stirring motor 353 disposed on the first ink cartridge 313 to drive the stirring blade 351 inside the first ink cartridge 313 to rotate, it is possible to avoid completely removing the stirring mechanism 35 from the first ink cartridge 313 for maintenance, reducing the opening structure for disassembling and assembling the stirring mechanism 35 inside the first ink cartridge 313, and reducing ink leakage in the first ink cartridge 313. Of course, in other embodiments, the stirring mechanism 35 can also adopt ultrasonic vibration. This application does not limit the type of stirring mechanism 35, as long as it can agitate the ink inside the first ink cartridge 313.

[0173] Furthermore, the first ink cartridge 313 may be provided with a first ink outlet and a second ink outlet. One end of the ink supply pipeline 33 is connected to the first ink outlet, and the ink supply pipeline 33 is provided with a return ink branch pipe, which is connected to the second ink outlet. The ink supply pipeline 33 can draw ink from the first ink cartridge 313 through the first ink outlet. By providing a return ink branch pipe on the ink supply pipeline 33, some of the ink in the first ink cartridge 313 can circulate through the ink supply pipeline 33, which helps to prevent the ink in the first ink cartridge 313 from sitting still and having a certain probability of condensation, further ensuring the fluidity of the ink in the ink supply module 300.

[0174] In some embodiments, please refer to FIG15, the housing 700 also includes a cable chain structure 77, which is movably disposed and has a tubing channel therein, through which the ink supply line 33 passes.

[0175] In this embodiment, the ink supply lines 33 are routed via a cable chain structure 77. This cable chain structure 77 binds multiple lines together, achieving a neat arrangement of the ink supply lines 33 within the housing 700. This reduces interference between the ink supply lines 33 and other components within the housing 700, better realizing the compact design of the inkjet printing device 1000. Furthermore, the cable chain structure 77 allows the ink supply lines 33 to move more stably with the printhead 100, reducing the dragging force on the ink supply lines 33 and better preventing leakage between the ink supply module 300 and the printing module 13.

[0176] Please refer to Figures 4, 16 and 27. In some embodiments of this application, the inkjet printing apparatus 1000 further includes an ink stack module 400, which is used to clean and / or moisturize the printing module 13 of the printhead 100.

[0177] In this embodiment, the ink stack module 400 can be used to clean and / or moisturize the printing module 13, which helps to prevent ink from condensing and clogging the printhead of the printing module 13, thus ensuring the stable operation of the printhead 100. The ink stack module 400 can clean the printing module 13 in various ways, such as scraping to remove condensed ink, or using a cleaning agent. Of course, combinations of cleaning methods are also possible, such as scraping followed by cleaning. This application does not limit the cleaning method of the ink stack module 400, as long as it can effectively clean the printing module 13.

[0178] The ink stack module 400 can be set on one side of the print station 200 along the first direction, so that the print head 100 can be moved more easily from the print station 200 to the ink stack module 400 for cleaning or standby, which is conducive to a more compact structural design of the inkjet printing device 1000.

[0179] In some implementations, referring to Figures 27 and 28, the ink stack module 400 may have a cleaning surface. The ink stack module 400 includes a trigger structure 47 disposed on the cleaning surface. The trigger structure 47 is used to detect and position the print head 100.

[0180] For example, the trigger structure 47 can be a protrusion on the cleaning surface. By setting a groove at a corresponding position on the printing module 13, the print head 100 can be positioned above the ink stack module 400. When the cleaning structure of the ink stack module 400 contacts the printing module 13, the protrusion is inserted into the groove. At this time, a corresponding trigger sensor can be set in the protrusion or the groove, so that the controller of the inkjet printing device 1000 can know that the print head 100 is positioned on the ink stack module 400. At this time, the ink stack module 400 can be stably started to clean the printing module 13, achieving precise positioning of the print head 100 and the ink stack module 400. When the trigger structure 47 is not triggered, a stop operation signal can be sent to the ink stack module 400 to avoid the ink stack module 400 from spinning idly or leaking due to the print head 100 shifting off the ink stack module 400, thus ensuring precise cleaning of the print head 100 by the ink stack module 400. Of course, in other embodiments, the trigger structure 47 may also be a pressure sensor, a distance sensor, etc. This application does not limit the type of trigger structure 47, as long as it can realize the corresponding detection between the print head 100 and the ink stack module 400.

[0181] Referring to Figures 27 and 28, in some embodiments, the ink stack module 400 may include an ink stack platform 41 and an ink pad 42. The top surface of the ink stack platform 41 is provided with a sludge collection tank 411, and the ink pad 42 is disposed within the sludge collection tank 411. In this case, when the print head 100 is placed on the ink stack module 400 for cleaning, the print module 13 can come into contact with the ink pad 42. The ink pad 42 can be a cleaning pad with a certain function of absorbing condensed ink, or a cleaning pad with a certain function of wiping condensed ink, etc. This application does not limit the type of ink pad 42, as long as it can achieve the cleaning function of the print module 13. By using the ink pad 42 disposed within the sludge collection tank 411 of the ink stack platform 41, the dirt or wastewater generated by the ink pad 42 in cleaning the print module 13 can be collected in the sludge collection tank 411, preventing dirt or wastewater from splashing within the inkjet printing device 1000. The shape of the ink stack 41 can be a regular shape, such as a square or a circle. Of course, the ink stack 41 can also be an irregular shape, and this application does not limit this.

[0182] In some embodiments, the ink stack module 400 may further include a scraper 43, which is disposed in the sludge collection tank 411 and arranged side by side with the ink pad 42. It is understood that the scraper 43 and the ink pad 42 can be arranged side by side along a first direction, so that the print head 100 contacts the scraper 43 before contacting the ink pad 42 during its movement from the print table 200 to the ink stack module 400. This allows the scraper 43 to better scrape off the ink that has solidified on the print module 13, and the ink pad 42 then cleans the print module 13, ensuring it remains in good condition for printing. The scraper 43 may be made of materials such as silicone or rubber to provide a certain degree of flexibility and prevent scratching the print module 13. Of course, the scraper 43 can also be made of other materials. This application does not limit the shape and material of the scraper 43, as long as it can effectively clean the print module 13.

[0183] In some embodiments, a blade holder 413 is provided in the sludge collection tank 411, and a scraper 43 is detachably connected to the blade holder 413. This detachable structure of the scraper 43 on the ink stack 41 facilitates better maintenance or replacement of the scraper 43, preventing damage to the scraper 43 from affecting the cleaning effect of the ink stack module 400 on the printing module 13, and further improving the practicality of the inkjet printing device 1000. The scraper 43 can be installed on the blade holder 413 by snap-fit ​​or by bolts. There are many ways to connect the blade holder 413 and the scraper 43, and this application does not limit this method, as long as a stable connection and convenient disassembly / removal of the scraper 43 and the blade holder 413 can be achieved.

[0184] In addition, the ink stack module 400 also includes a shielding cover 44, which can open or close the opening of the sludge collection tank 411. The shielding cover 44 is provided with a first clearance hole 441, through which the ink pad 42 passes. By providing a shielding cover 44 at the opening of the sludge collection tank 411, the sludge collection tank 411 can be shielded, preventing dirt or wastewater in the sludge collection tank 411 from being exposed and affecting the aesthetics of the inkjet printer 1000. At the same time, it helps to prevent dirt or wastewater in the sludge collection tank 411 from splashing out due to shaking of the inkjet printer 1000 during transportation or handling. There may be a certain gap between the outer periphery of the ink pad 42 and the inner wall of the first clearance hole 441, or the inner wall of the first clearance hole 441 may be recessed with a flow groove so that the dirt or sewage after the ink pad 42 is cleaned can flow steadily into the dirt collection tank 411 through the first clearance hole 441, reducing the accumulation of dirt or sewage on the cover plate 44.

[0185] When the ink stack module 400 is equipped with a scraper 43, the shielding cover 44 can also be provided with a second clearance hole 443 for the scraper 43 to pass through, ensuring stable cleaning of the printing module 13 by the ink stack module 400. There can be a certain gap between the outer periphery of the scraper 43 and the inner wall of the second clearance hole 443, or the inner wall of the second clearance hole 443 can be recessed with a flow groove, so that the dirt or wastewater after cleaning the ink pad 42 can flow steadily into the dirt collection tank 411 through the second clearance hole 443, reducing the accumulation of dirt or wastewater on the shielding cover 44.

[0186] Referring to Figures 27 and 28, in some embodiments of this application, the ink stack module 400 further includes a fourth drive mechanism 45, which is connected to the ink stack platform 41 to enable the ink stack platform 41 to have a clean state close to the print station 200 and a clearance state away from the print station 200. It is understood that when the print head 100 needs cleaning, the fourth drive mechanism 45 can be controlled to move the ink stack platform 41 so that the ink pad 42 contacts the print module 13 for cleaning; and when the print head 100 needs to leave the ink stack module 400, the fourth drive mechanism 45 can be controlled to move the ink stack platform 41 away from the print head 100, thus facilitating better automated control of the ink stack module 400. The fourth drive mechanism 45 can drive the ink stack 41 to move up and down. Alternatively, the fourth drive mechanism 45 can drive the ink stack 41 to move horizontally. This application does not limit the transmission method of the fourth drive mechanism 45, as long as it can realize the movement switching of the ink stack 41 in the cleaning state and the avoidance state.

[0187] For example, the fourth drive mechanism 45 may include a fourth support frame 451, a drive motor 453, a lead screw 455, a transmission slider 457, and a transmission connecting rod 459. The lead screw 455 is rotatably connected to the fourth support frame 451. The drive motor 453 is connected to and drives the lead screw 455 to rotate. The transmission slider 457 is sleeved on the lead screw 455 and disposed within the fourth support frame 451. The transmission connecting rod 459 connects the transmission slider 457 and the ink stack 41. By using the drive motor 453 to drive the lead screw 455 to rotate, the transmission slider 457 can slide on the fourth support frame 451 under the transmission action of the lead screw 455. In turn, the translation of the transmission slider 457 pushes the transmission connecting rod 459 to drive the ink stack 41 to move up and down, ensuring stable switching of the ink stack 41 between the cleaning state and the avoidance state. In some embodiments, the fourth support frame 451 has two opposing side plates 4511, and at least a portion of the structure of the ink stack 41 is disposed between the two side plates 4511. The side plates 4511 have a first elongated hole 4511a extending in a first direction and a second elongated hole 4511b extending in a third direction. One end of the transmission link 459 passes through the first elongated hole 4511a and connects to the transmission slider 457, while the other end of the transmission link 459 passes through the second elongated hole 4511b and connects to the ink stack 41. Under the action of the first elongated hole 4511a and the second elongated hole 4511b, the movement limit of the transmission link 459 can be effectively achieved, allowing the transmission link 459 to more stably push the ink stack 41 up and down under the translational drive of the transmission slider 457, ensuring a stable transmission connection between the fourth drive mechanism 45 and the ink stack 41. In some embodiments, the fourth drive mechanism 45 may be provided with at least two transmission links 459 on opposite sides of the transmission slider 457, so that the transmission power of the fourth drive mechanism 45 to the ink stack 41 is more uniform and stable, avoiding deviation during the lifting and lowering of the ink stack 41, and further improving the movement stability and reliability of the ink stack 41.

[0188] In some embodiments of this application, the ink stack module 400 further includes a water inlet pipe 46 and a drain pipe. The water inlet pipe 46 is connected to the ink pad 42, and the drain pipe is connected to the ink stack platform 41 and communicates with the sludge collection tank 411. The ink pad 42 may have internal pipes to enable it to perform a certain water spray cleaning function. By connecting the water inlet pipe 46 to the ink pad 42, a certain amount of clean water or cleaning fluid can be introduced into the internal pipes of the ink pad 42 and flow out through the outlet on the surface of the ink pad 42 to clean the printing module 13, further improving the cleaning effect of the ink stack module 400. The drain pipe can stably discharge wastewater or dirt from the sludge collection tank 411, preventing excessive accumulation of wastewater that could overflow, mold, or produce odors, further improving the reliability of the ink stack module 400. The end of the water inlet pipe 46 furthest from the ink pad 42 can be connected to a water supply device outside the inkjet printer 1000. Alternatively, if the ink supply module 300 has a water purification box 317 storing a certain amount of purified water, the water inlet pipe 46 can be connected to the water supply pipe of the ink supply module 300. In this case, if the ink supply module 300 is located inside the housing 700 of the inkjet printer 1000, a connector connecting the water inlet pipe 46 and the water supply pipe can be provided inside the housing 700, so that the water inlet pipe 46 and the water supply pipe are respectively connected to the two ends of the connector, which facilitates the disassembly, assembly, and maintenance of the ink stack module 400 and the ink supply module 300. Of course, water can also be supplied to the water inlet pipe 46 in other ways. This application does not limit this, as long as it can achieve a stable flow of purified water or cleaning fluid into the water inlet pipe 46. The end of the drain pipe furthest from the ink stack 41 can be connected to a waste liquid collection device outside the inkjet printer 1000. Alternatively, if a waste liquid box 500 is provided inside the housing 700 of the inkjet printer 1000, the drain pipe can be connected to the waste liquid box 500 to ensure stable discharge of wastewater or dirt from the sludge collection tank 411. In this case, a connector structure connecting the drain pipe and the waste liquid box 500 can be provided inside the housing 700 to facilitate the disassembly, assembly, and maintenance of the ink stack module 400 and the waste liquid box 500. Of course, other methods can also be used to discharge wastewater; this application does not limit this, as long as stable discharge management can be achieved.

[0189] In some embodiments, when the ink stack module 400 drives the ink stack platform 41 to move using a drive mechanism, the support base of the drive mechanism has a first inner sidewall and a second inner sidewall connected to each other. A first pressure fitting is connected to the first inner sidewall, and a second pressure fitting is connected to the second inner sidewall. The drain pipe and the water inlet pipe 46 are fixed to the first and second pressure fittings, so that the drain pipe and the water inlet pipe 46 are arranged close to the first and second inner sidewalls. Under the limiting and fixing action of the first and second pressure fittings, interference between the drain pipe and the driving component of the drive mechanism can be effectively avoided within the support base of the drive mechanism, realizing the avoidance arrangement of the pipes and ensuring the stable operation of the ink stack module 400.

[0190] Please refer to Figures 16 and 29. In some embodiments of this application, the inkjet printing apparatus 1000 further includes a waste liquid container 500 for collecting waste liquid generated by the inkjet printing apparatus 1000. In some embodiments, the waste liquid container 500 can be connected to the ink stack module 400 pipeline of the inkjet printing device 1000, so that the wastewater or dirt generated by the ink stack module 400 using clean water to clean the printing module 13 can be transported to the waste liquid container 500 for collection. In addition, the waste liquid container 500 can also be connected to the ink supply module 300 or the printing module 13 pipeline, so that the ink overflowing from the ink supply module 300 or the printing module 13 can be collected in the waste liquid container 500, avoiding the overflowing ink from contaminating the inkjet printing device 1000. Of course, the waste liquid container 500 can also be used for the discharge and collection of waste liquid overflowing from other components in the inkjet printing device 1000. This application does not limit the specific use of the waste liquid container 500, as long as it can realize the discharge of waste liquid generated by the inkjet printing device 1000.

[0191] In some embodiments, when the inkjet printer 1000 has a housing 700, the waste liquid container 500 can be disposed within the receiving space formed by the housing 700, and the waste liquid container can be detachably installed within the housing 700. Referring to Figure 35, in some embodiments, the inlet of the waste liquid container 500 is provided with a first tube head structure 51, which has an inlet channel 511. The portion of the first tube head structure 51 disposed within the waste liquid container 500 has an outlet hole 513 communicating with the inlet channel 511. Two one-way valves 515 are arranged sequentially inside the tube head. A second tube head structure 78 can be disposed within the housing 700. The second tube head structure 78 can be inserted into the first tube head structure 51, so that a portion of the second tube head structure 78 extends into the first tube head structure 51 and pushes against the one-way valves 515. The second tube head structure 78 is connected to the drain pipe within the inkjet printer 1000. Furthermore, when the waste liquid box 500 is assembled into the housing 700, the sewage pipe can be connected to the waste liquid box 500 by using the first pipe head structure 51 and the second pipe head structure 78 in a plug-in manner. When the waste liquid box 500 is removed from the housing 700, the second pipe head structure 78 releases its push on the one-way valve 515, and the elastic reset of the one-way valve 515 can close the first pipe head structure 51, preventing leakage of sewage or dirt from the waste liquid box 500, thus achieving convenient installation and removal of the waste liquid box 500 from the housing 700. Of course, this application is not limited to this. In other embodiments, the waste liquid box 500 can also be connected to the sewage pipe in the housing 700 using other connection structures. This application does not limit the connection structure between the waste liquid box 500 and the housing 700, as long as it can achieve stable installation of the waste liquid box 500 in the housing 700 and pipe connection.

[0192] In some embodiments, referring to Figures 29 and 30, a positioning detection mechanism 79 may be provided within the housing 700. This mechanism 79 detects whether the waste liquid container 500 is properly assembled, ensuring stable pipeline connectivity after assembly within the housing 700 and effectively preventing leakage at the connection points. The positioning detection mechanism 79 may include a Hall sensor located within the housing 700. In this case, a corresponding magnetic trigger structure 47 can be provided on the waste liquid container 500 so that the magnet and Hall sensor can be activated when the waste liquid container 500 is properly installed. However, this application is not limited to this; the positioning detection mechanism 79 may also employ a limit switch or other methods to achieve the positioning detection of the waste liquid container 500.

[0193] Please refer to Figures 30 and 31. In some embodiments of this application, the waste liquid box 500 may also be provided with a waste liquid detection mechanism 53, which is used to detect the liquid level in the waste liquid box 500. For example, a rotatable second detection float 531 can be provided inside the waste liquid box 500. When the liquid level in the waste liquid box 500 rises or falls, the second detection float 531 can swing and rise or fall to a certain extent with the change in liquid level. At this time, a second detection signal 533 can be provided on the top of the waste liquid box 500, and a second detection transmitter can be provided inside the second detection float 531. When the liquid level in the waste liquid box 500 rises to a certain height, the second detection float 531 can be raised to a certain position. At this time, the second detection transmitter and the second detection signal 533 are triggered relative to each other, so that the second detection signal 533 can send a waste liquid box 500 full signal to the controller of the inkjet printing device 1000, reminding to remove the waste liquid box 500 for discharge or replacement, effectively avoiding the risk of waste liquid overflow due to the waste liquid box 500 being full. The second detection signal device 533 can be a Hall sensor, and the second detection transmitter can be a magnet. Of course, the second detection transmitter and the second detection signal device 533 can also be contact-type signal transmitters and detectors, which are not limited in this application.

[0194] Please refer to Figures 2, 3 and 32. In some embodiments of this application, the inkjet printing apparatus 1000 includes a material rack 800 for loading the material to be printed.

[0195] In this embodiment, the material to be printed is loaded onto the material rack 800. The material can be rolled and wound around the material rack 800, or it can be stacked on top of the material rack 800, so that the material can be stably and continuously fed to the printing table 200 for printing. Of course, in other embodiments, other methods can be used to load the material. This application does not limit the loading method of the material rack 800, as long as it can achieve stable support and transport of the printing material.

[0196] In the inkjet printing device 1000, when the housing 700 is included to form the overall support structure, the material rack 800 and the housing 700 can be integrally molded; alternatively, the material rack 800 can be detachably connected to the housing 700, that is, the material rack 800 and the housing 700 can be separate structures. In this case, the material rack 800 can be equipped with hooks, which can be used to attach to the printing material inlet 75a of the housing 700 to achieve the assembly and disassembly of the material rack 800. Alternatively, the material rack 800 can be detached and fixed to the housing 700 using fasteners such as bolts. Of course, snap-fit ​​connections or other methods can also be used to detach and connect the material rack 800 and the housing 700. This application does not limit the connection method between the material rack 800 and the housing 700.

[0197] Referring to Figures 32 to 35, in some embodiments, the material rack 800 includes a fifth support frame 81, a fixed shaft 83, and a material roll structure 85. The fixed shaft 83 is connected to the fifth support frame 81, and the material roll structure 85 is sleeved on the fixed shaft 83 for loading the material to be printed. The material rack 800 can allow the material to be printed to be sleeved on the material roll structure 85, and the material to be printed can be released and transported by the relative rotation between the material roll structure 85 and the fixed shaft 83; alternatively, the fixed shaft 83 can be fixedly connected to the material roll structure 85, allowing the fixed shaft 83 to rotate on the fifth support frame 81 to release and transport the material to be printed; or the material roll structure 85 can be fixedly connected to the fixed shaft 83, and the fixed shaft 83 can be fixedly connected to the fifth support frame 81, allowing the material to be printed and the material roll structure 85 to rotate relative to each other for release and transport.

[0198] In some embodiments, the fixed shaft 83 may be a square shaft. The fixed shaft 83 is connected and fixed to the fifth support frame 81. By fixing the fixed shaft 83 on the fifth support frame 81, the bearing structure between the fixed shaft 83 and the fifth support frame 81 can be reduced, which is beneficial to simplify the structure of the material rack 800 and reduce the production cost of the material rack 800 structure.

[0199] Furthermore, referring to Figures 32 to 35, in some embodiments, the material roll structure 85 may include a first sleeve 851 and a second sleeve 853, which are spaced apart and sleeved on the fixed shaft 83. The distance between the first sleeve 851 and the second sleeve 853 is adjustable, and the first sleeve 851 and the second sleeve 853 are used to accommodate the material to be printed. By adjusting the distance between the first sleeve 851 and the second sleeve 853 on the fixed shaft 83, the material roll structure 85 can better load printing materials of various sizes, improving the adaptability of the material rack 800.

[0200] Referring to Figures 33 and 35, in some embodiments, the first sleeve 851 includes a material clamp 8511 and a first bearing sleeve 8513. The material clamp 8511 is fixedly connected to the fixed shaft 83, and the first bearing sleeve 8513 is sleeved on the fixed shaft 83 and connected to the material clamp 8511. By using the material clamp 8511 to connect and fix the first bearing sleeve 8513, the first bearing sleeve 8513 can be connected to the material clamp 8511 after being loaded with printing material, ensuring the coaxiality of the first sleeve on the fixed shaft 83. For example, the inner wall of the first bearing sleeve 8513 may be provided with internal threads, and the outer periphery of the material clamp 8511 may be provided with external threads. The first bearing sleeve 8513 and the material clamp 8511 are connected by a threaded engagement. The threaded connection method can achieve a more convenient installation method for the first bearing sleeve 8513 and the material clamp 8511. In some embodiments, a fourth elastic element 8515 is provided between the first bearing sleeve 8513 and the material clamp 8511. The fourth elastic element 8515 can be a spring, a rubber pad, etc. This application does not limit the structure of the fourth elastic element 8515. By using the fourth elastic element 8515 between the first bearing sleeve 8513 and the material clamp 8511, the connection stress between the first bearing sleeve 8513 and the material clamp 8511 can be prevented from being too large and thus have a certain probability of breaking, thereby further improving the structural stability and reliability of the material rack 800.

[0201] In some embodiments, please refer to Figures 33 and 34. In some embodiments, a ratchet structure 831 may be provided on the fixed shaft 83. The second sleeve 853 includes a second bearing sleeve 8531 and a retaining ring 8533. The second bearing sleeve 8531 is sleeved on the fixed shaft 83. The retaining ring 8533 is connected to the second bearing sleeve 8531. The retaining ring 8533 is provided with a telescopic buckle 8533a. The telescopic buckle 8533a can be engaged with the ratchet structure 831. By moving the telescopic buckle 8533a on the retaining ring 8533, the telescopic buckle 8533a can be engaged with the ratchet structure 831, thereby fixing the retaining ring 8533 and the second bearing sleeve 8531 on the fixed shaft 83. When it is necessary to adjust the distance between the second sleeve 853 and the first sleeve 851, the engagement between the telescopic buckle 8533a and the ratchet structure 831 can be released, allowing the second bearing sleeve 8531 to slide on the fixed shaft 83. Once the distance between the second bearing sleeve 8531 and the first sleeve 851 meets the adjustment requirements, the telescopic buckle 8533a of the retaining ring 8533 can be engaged with the ratchet structure 831 to fix it. This allows the material rack 800 to more conveniently adjust the first sleeve 851 and the second sleeve 853 to load and transport the material to be printed.

[0202] Of course, in other embodiments, the first set of cylindrical members 851 and the second set of cylindrical members 853 may also adopt other structural arrangements. This application does not limit the shape and structure of the first set of cylindrical members 851 and the second set of cylindrical members 853, as long as they can achieve stable installation on the fixed shaft 83 and bear the material to be printed.

Furthermore, the material ejector 900 can have a certain area of ​​supporting surface so that the processed printing material can be laid flat on the supporting surface, preventing the printing material from folding during output and causing a certain probability of creases, further improving the practicality and processing reliability of the inkjet printing device 1000.

[0204] In some embodiments, the discharge tray 900 is detachably connected to the housing 700, which facilitates the removal of the discharge tray 900 from the housing 700 during storage or packaging and transportation of the inkjet printing device 1000, reducing the space occupied by the inkjet printing device 1000 in storage and packaging. The discharge tray 900 can be connected to the housing 700 via a protruding plug-in connection, or it can be connected to the housing 700 using a combination of a slider and a slide rail. Alternatively, the discharge tray 900 can be designed to be fixedly connected to the housing 700; this application does not limit the connection method between the discharge tray 900 and the housing 700.

[0205] In some embodiments, the discharge bracket 900 may include at least two trays 91, which can be extended or stacked. It is understood that by providing a connecting structure of mutually cooperating sliders and slide rails between adjacent trays 91, or by using rotatable connecting rods to connect adjacent trays 91, a certain number of trays 91 can be extended as needed to increase the supporting surface area of ​​the discharge bracket 900, or a certain number of trays 91 can be stacked as needed to reduce the space occupied by the discharge bracket 900, so that the discharge bracket 900 better meets the actual processing needs and further improves the practicality of the inkjet printing device 1000. There are many other ways to extend and stack the trays 91, such as not connecting multiple trays 91, that is, separating multiple trays 91 and splicing them together when extension is needed, or stacking multiple trays 91 when space occupancy of the discharge bracket 900 needs to be reduced. This application does not limit the connection method of the at least two trays 91.
