[0066] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0067] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0068] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0069] In the related art, inkjet printing devices can spray ink onto printing materials such as paper, film, and cloth to accurately form the desired image or text on the printing materials, and can achieve high-definition printing operations. They are widely used in various industries. However, after printing the pattern, the inkjet printing device cannot automatically cut the printing material according to the size of the printed pattern. Usually, the printed material needs to be manually cut after printing out to reach the required size, which is inconvenient.

[0070] In view of the above problems, in order to solve the problem that the inkjet printing device cannot adjust the size of the printed material after printing, the present invention proposes an inkjet printing device 1000. It should be noted that the inkjet printing device proposed in this application can be a thermal inkjet printer, a piezoelectric inkjet printer, or a white ink heat transfer printer ("Direct to Film", DTF printer), a white ink direct jet printer ("Direct to Garment", DTG printer), etc., as long as it is a device used for jetting ink for printing operations. The printing material operated by the inkjet printing device in this application can be paper, film material, and of course, cloth, etc. This application does not limit the material and shape of the printing material, and the material that can be printed in the inkjet printing device can be used.

[0071] See also Figures 1 to 5 In one embodiment of the present invention, the inkjet printing device 1000 includes a printing 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 printing table 200 and is used to print the printing material disposed on the printing 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 printing table 200, and the cutter module 15 is used to cut the printing material on the printing table 200.

[0072] The printing table 200 can form a bearing structure for the whole machine to operate and process, so that the print head 100 can stably print and process the printing material carried on the printing table 200, ensuring the stable operation of the inkjet printing device 1000. The printing table 200 can be set in a regular shape, such as a cube, a truncated cone, etc., and of course, it can also be set in an irregular shape. The specific shape of the printing table 200 is not limited in this application. The printing table 200 can be used to support the printing material.

[0073] The print head 100 may be integrated with ink nozzles, control components, etc., so that the ink supplied by the ink supply module 300 can be accurately sprayed onto the printing material. The principle of the print head 100 spraying ink to perform printing operations is a prior art, so the structure of the print head 100 is not limited. Among them, by making the print head 100 movably arranged above the printing table 200, the print head 100 can be driven to move by a track transmission device, or the print head 100 can be driven to move by a mechanical arm or other device. The present application does not limit the movement mode of the print head 100, and it is sufficient to realize the movement of the print head 100 on the printing table 200. In addition, the print head 100 can perform printing operations according to a certain movement path, so that the print head 100 can better spray ink on the printing material to form the desired image or text.

[0074] The ink supply module 300 can be connected to the print head 100 through a pipeline to transport ink, or the ink supply module 300 can be set in the print head 100 to directly transport ink to the print nozzle in the print head 100. Of course, the ink supply module 300 can also use other methods to supply ink to the print head 100, as long as it can ensure that the ink is stably transported to the print head 100 for inkjet printing, and this application does not limit this.

[0075] By movably arranging the cutter module 15 above the printing table 200, the cutter module 15 can be used to cut the printing material placed on the printing table 200, thereby adjusting the size of the printing material. This is beneficial for directly cutting the printing material during the printing process, so that the inkjet printing device 1000 can directly output the processed printing material of the required size, thereby achieving a more convenient and reliable printing process of the inkjet printing device 1000. Among them, the cutter module 15 can be set on the print head 100, and the movement of the print head 100 can be used to synchronously drive the cutter module 15 to move. At this time, the cutter module 15 can be set inside the print head 100, or the cutter module 15 can be set on the side of the print head 100; of course, in addition to using the print head 100 to drive the cutter module 15 to move synchronously, the cutter module 15 and the print head 100 can also adopt a connection structure composed of a slide rail and a slider, so that the cutter module 15 can move relative to the print head 100 to cut the printed material; or, the cutter module 15 can also be set above the printing table 200 in a lifting and moving manner, so that the cutter module 15 can cut the printed material in a lifting and pressing cutting manner. Therefore, there are many ways to install the cutter module 15 and cut the printed material, and the present application does not limit this.

[0076] The technical solution of the present invention is to set a cutter module 15 above the printing table 200, and the cutter module 15 can be used to cut the printing material on the printing table 200, so that after the print head 100 prints the printing material, the cutter module 15 can be used to directly cut the printing material into the required size, thereby realizing one-time printing and forming on the inkjet printing device 1000, without the need to manually cut the printing material after printing output, effectively improving the printing convenience and practicality of the inkjet printing device 1000.

[0077] See also Figures 1 to 4 In some embodiments of the present application, the inkjet printing device 1000 further includes a housing 700, a receiving space is formed in the housing 700, and the printing table 200, the print head 100 and the cutter module 15 are arranged in the receiving space.

[0078] It is understandable that by placing the printing table 200, the print head 100 and the cutter module 15 in the receiving space, the printing process of the inkjet printing device 1000 can be carried out in a certain closed environment, which is conducive to using the housing 700 to play a certain role of isolation and protection, effectively reducing the interference of environmental debris on the printing process, and ensuring the stable operation of the printing process. Among them, the housing 700 can be set in an integrated structure, or the housing 700 can be formed by splicing multiple shells. The present application does not limit the shape of the housing 700.

[0079] Furthermore, the inkjet printing device 1000 can also set the ink supply module 300 in the receiving space to achieve a more functionally integrated structural design of the inkjet printing device 1000. In this case, the ink supply module 300 can be set behind the print head 100 to prevent the ink supply module 300 from interfering with the print head 100 performing printing operations on the printing table 200, so that the various components of the inkjet printing device 1000 can be more reasonably laid out in the receiving space, which is convenient for the compact design of the inkjet printing device 1000 and further improves the practicality and reliability of the inkjet printing device 1000. For ease of understanding and explanation, the present application is based on Fig.16 The directions indicated by the coordinate system shown in the figure are for reference, wherein 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 of the x-axis is left; the positive direction of the y-axis is front, and the negative direction of the y-axis is back; the positive direction of the z-axis is up, and the negative direction of the z-axis is down.

[0080] See also Figure 1 In some embodiments of the present application, the housing 700 is provided with a first opening 71a connected to the receiving space, and the first opening 71a is located above the printing table 200. The housing 700 also includes a first cover plate 71b, and the first cover plate 71b can open or cover the first opening 71a.

[0081] In the present application, by opening the first opening 71a above the printing table 200 in the housing 700, the operating conditions of the print head 100, the printing table 200 or other components disposed in the receiving space can be observed through the first opening 71a, which is conducive to timely intervention, repair or replacement of faulty components, and ensures the stable operation of the inkjet printing device 1000. The first opening 71a can be set in a regular shape, such as a rectangle, a circle, etc., and of course, it can also be set in an irregular shape. The present application does not limit the shape of the first opening 71a.

[0082] By setting the first cover plate 71b to open or cover the first opening 71a, the first cover plate 71b can be connected to the casing 700, for example, the first cover plate 71b is rotatably connected to the casing 700 to open or cover the first opening 71a, or the first cover plate 71b is slidably connected to the casing 700 to open or cover the first opening 71a; of course, the first cover plate 71b and the casing 700 can also be separately set, and the first cover plate 71b is detached from the casing 700 when the first opening 71a needs to be opened, and the first cover plate 71b is covered on the casing 700 when the first opening 71a needs to be covered. Therefore, there are many ways to connect the first cover plate 71b to the casing 700, and the present application does not limit this. The first cover plate 71b can be made of a material with a certain degree of light transmittance, such as glass, acrylic, etc., which is conducive to observing the operating conditions of the components in the receiving space through the first cover plate 71b when the first cover plate 71b covers the first opening 71a; of course, the first cover plate 71b can also be made of steel with higher structural strength, and the present application does not limit the material of the first cover plate 71b. In addition, the first cover plate 71b can be set in a regular shape, such as square, round, etc., and of course, it can also be set in an irregular shape, and the present application does not limit the shape of the first cover plate 71b. Among them, the first cover plate 71b can be transparent or translucent, so that the printing inside can be directly observed through the first cover plate 71b.

[0083] Furthermore, the housing 700 may be provided with an opening and closing detection device, which is used to detect the opening and closing state of the first cover plate 71b. It is understandable that the opening and closing detection device may have two triggering states. When the first cover plate 71b covers the first opening 71a, it may correspond to triggering one triggering state of the opening and closing detection device, and when the first cover plate 71b opens the first opening 71a, it may correspond to triggering another triggering state of the opening and closing detection device, and then certain system control may be performed according to the state change of the opening and closing detection device. For example, when the opening and closing detection device detects that the first cover plate 71b opens the first opening 71a, the components of the receiving space may be regulated to be in a suspended operation state, which is convenient for the inspection and maintenance of the components; or the printing operation may be started only when the state of the opening and closing detection device detects that the first cover plate 71b covers the first opening 71a, etc. Similarly, the opening and closing detection device may also be linked with other control systems, which is not limited in this application. There are many kinds of structures of the opening and closing detection device. For example, a travel switch can be used, so that the first cover plate 71b contacts the triggering part of the travel switch when the first cover plate 71b covers the first opening 71a, and leaves the triggering part of the travel switch when the first cover plate 71b opens the first opening 71a; or a Hall sensor can be used, and a magnet can be set on the first cover plate 71b at this time, so that when the first cover plate 71b covers the first opening 71a, the magnet is close to the Hall sensor, and when the first cover plate 71b opens the first opening 71a, the magnet is away from the Hall sensor. The present application does not limit the opening and closing detection device.

[0084] See also Figure 2 In some embodiments of the present application, when the ink supply module 300 is disposed in the receiving space, the housing 700 may be provided with a second opening 72a connected to the receiving space. The second opening 72a may correspond to being located above the ink supply module 300, or may correspond to being located behind the ink supply module 300. The present application does not limit the position of the second opening 72a, and it is sufficient that the ink supply module 300 can be exposed through the second opening 72a.

[0085] The second opening 72a can be set in a regular shape, such as a rectangle, a circle, etc., or in an irregular shape. The present application does not limit the shape of the second opening 72a. Furthermore, the ink supply module 300 can be filled with ink, repaired and maintained, and the pipeline can be dredged through the second opening 72a to ensure the stable operation of the inkjet printing device 1000. The casing 700 may further include a second cover plate 72b, which may open or cover the second opening 72a. The second cover plate 72b may be connected to the casing 700, for example, the second cover plate 72b may be slidably connected to the casing 700 to open or cover the second opening 72a, or the second cover plate 72b may be rotatably connected to the casing 700 to open or cover the second opening 72a. Of course, the second cover plate 72b may also not be connected to the casing 700, that is, the second cover plate 72b and the casing 700 are separately arranged. When the second opening 72a needs to be covered, the second cover plate 72b is placed on the casing 700, and when the second opening 72a needs to be opened, the second cover plate 72b is removed from the casing 700. There are many ways to connect the second cover plate 72b to the casing 700, and the present application does not limit this.

[0086] Exemplarily, the second cover plate 72b is provided with a first magnetic part, and the housing 700 is provided with a second magnetic part around the second opening 72a, and the second cover plate 72b is connected to the housing 700 by magnetic attraction. The first magnetic part can be a magnet with a certain magnetism, in which case the second magnetic part can be a magnet with a magnetism opposite to that of the first magnetic part or a metal part that can be magnetically attracted, etc.; or, the second magnetic part can be a magnet with a certain magnetism, in which case the first magnetic part can be a magnet with a magnetism opposite to that of the first magnetic part or a metal part that can be magnetically attracted, etc., and the first magnetic part and the second magnetic part can achieve mutual magnetic attraction, and this application does not limit this. By making the second cover plate 72b connected to the housing 700 by magnetic attraction, the second cover plate 72b can be opened and closed on the housing 700 more conveniently, further improving the operating convenience of the inkjet printing device 1000.

[0087] See also Figure 3 In some embodiments of the present application, when the inkjet printing device 1000 is provided with an ink stack module 400 and a waste liquid box 500, and the waste liquid box 500 is provided in the receiving space, the housing 700 may be provided with a third opening 73a connected to the receiving space on a side adjacent to the waste liquid box 500, so that the waste liquid box 500 can be exposed through the third opening 73a, which is conducive to more conveniently disassembling and assembling the waste liquid box 500 through the third opening 73a, further improving the convenience of operation of the inkjet printing device 1000. The third opening 73a may be provided in a regular shape, such as a rectangle, a circle, etc., and of course, may also be provided in an irregular shape, and the present application does not limit the shape of the third opening 73a.

[0088] Further, the housing 700 may be provided with a third cover plate 73b for covering or opening the third opening 73a, so as to ensure the integrity and aesthetics of the housing, and to facilitate the disassembly and assembly of the waste liquid box 500 on the housing 700. The third cover plate 73b may be connected to the housing 700, for example, the third cover plate 73b is slidably connected to the housing 700 to open or cover the third opening 73a, or the third cover plate 73b is rotatably connected to the housing 700 to open or cover the third opening 73a; of course, the third cover plate 73b may not be connected to the housing 700, that is, the third cover plate 73b and the housing 700 are separately provided, and the third cover plate 73b is placed on the housing 700 when the third opening 73a needs to be covered, and the third cover plate 73b is detached from the housing 700 when the third opening 73a needs to be opened. There are many ways to connect the third cover plate 73b to the housing 700, and this application does not limit this.

[0089] In addition, the ink stack module 400 can be arranged in the receiving space and on the moving path of the print head 100. The ink stack module 400 can be used to clean the printing module 13 of the print head 100 to prevent the inkjet outlet of the printing module 13 from being blocked or contaminated. When the print head 100 performs a printing operation for a certain period of time or pauses the operation and is in standby, the print head 100 can be adjusted to a trimming state at this time, so that the print head 100 moves to the top of the ink stack module 400 for cleaning or docking, so that the print head 100 can better perform subsequent printing operations, further improving the practicality and reliability of the inkjet printing device 1000. For example, please refer to Figure 4 and Fig.16 When the print head 100 can reciprocate along the first direction to perform a printing operation, the ink stack module 400 can be arranged in the first direction with the printing table 200, that is, the ink stack module 400 can be arranged on the left or right side of the printing table 200, so as to facilitate the movement of the print head 100 between the ink stack module 400 and the printing table 200, and realize a more compact structural design of the inkjet printing device 1000. Of course, the ink stack module 400 and the printing table 200 can also be arranged in other ways in the receiving space, as long as they can cooperate with the movement of the print head 100, and this application does not limit this.

[0090] See also Figure 4 and Fig.16 In some embodiments of the present application, the inkjet printing device 1000 further includes a reflective structure 74, which is disposed near the printing table 200. The reflective structure 74 can be used to observe the operating status of the printing module 13 of the print head 100 or the sharpness of the cutter module 15, so as to facilitate the inspection and maintenance of the printing module 13 and the cutter module 15. The reflective structure 74 can be a reflector, or a metal part with a certain reflective effect, etc., which is not limited in the present application.

[0091] Exemplarily, the reflective structure 74 can be set on the moving path of the print head 100. At this time, the inkjet printing device 1000 can control the print head 100 to adjust to the first observation state, so that the print head 100 can stably move to the reflective structure 74 to observe the operating condition of the printing module 13; in addition, the reflective structure 74 can also be set on the moving path of the cutter module 15. At this time, the inkjet printing device 1000 can control the cutter module 15 to adjust to the second observation state, so that the cutter module 15 can stably move to the reflective structure 74 to observe the sharpness of the printing. Among them, the moving paths of the print head 100 and the cutter module 15 can be made to have at least partial overlap. For example, the cutter module 15 can be set on the print head 100 and move synchronously, so that the reflective structure 74 can be set at a certain overlapping position of the moving paths of the cutter module 15 and the print head 100; or, the reflective structure 74 can adopt a larger-sized structural design, so that the reflective structure 74 can be simultaneously located on a certain section of the moving path of the print head 100 and a certain section of the moving path of the cutter module 15. Of course, the reflective structure 74 can also adopt other structural designs to achieve that the reflective structure 74 is in the moving path of the print head 100 and the moving path of the cutter module 15, and the present application does not limit this.

[0092] In addition, see Fig.16 and Fig.17 When the print head 100 and the cutter module 15 can reciprocate along the first direction, the reflective structure 74 can be arranged in the first direction with the printing table 200, that is, the reflective structure 74 can be arranged on the left or right side of the printing table 200, so as to facilitate the movement of the print head 100 and the cutter module 15 between the reflective structure 74 and the printing table 200, and realize a more compact structural design of the inkjet printing device 1000. Of course, the reflective structure 74 and the printing table 200 can also be arranged in other ways in the receiving space, as long as they can cooperate with the movement of the print head 100 and the cutter module 15, and this application does not limit this.

[0093] In some embodiments, the housing 700 may be provided with 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, and the operation status of the print head 100 and the cutter module 15 can be understood, so as to facilitate timely cleaning of the print module 13 or maintenance and replacement of the cutter module 15. The fourth opening may be provided in a regular shape, such as a rectangle, a circle, etc., or in an irregular shape, and the present application does not limit the shape of the fourth opening.

[0094] Furthermore, the housing 700 may be provided with a fourth cover plate for covering or opening the fourth opening, so as to ensure the integrity and aesthetics of the housing, and at the same time facilitate observation of the print head 100 and the cutter module 15 through the reflective structure 74. The fourth cover plate may be connected to the housing 700, for example, the fourth cover plate is slidably connected to the housing 700 to open or cover the fourth opening, or the fourth cover plate is rotatably connected to the housing 700 to open or cover the fourth opening; of course, the fourth cover plate may not be connected to the housing 700, that is, the fourth cover plate and the housing 700 are separately provided, and the fourth cover plate is placed on the housing 700 when the fourth opening needs to be covered, and the fourth cover plate is detached from the housing 700 when the fourth opening needs to be opened. There are many ways to connect the fourth cover plate to the housing 700, and this application does not limit this.

[0095] See also Figures 1 to 3 In some embodiments of the present application, the housing 700 may also be provided with a printing material inlet 75a and a printing material outlet 75b on opposite sides, respectively. The printing material inlet 75a and the printing material outlet 75b may be provided with respect to the feeding side and the discharging side of the printing table 200, respectively, so that the printing material can be fed into the housing through the printing material inlet 75a for printing processing, and the printed printing material can be output through the printing material outlet 75b. The printing material inlet 75a and the printing material outlet 75b may be provided in regular rectangular, elliptical or other shapes, and of course, may also be provided in irregular shapes, and the shapes of the printing material inlet 75a and the printing material outlet 75b of the present application are not limited.

[0096] See also Figure 1 In some embodiments of the present application, the inkjet printing device 1000 may be provided with a display module 1001, which is conducive to using the display module 1001 to display at least part of the operating conditions of the inkjet printing device 1000, and at the same time facilitates more intuitive control of the inkjet printing device 1000, thereby improving the practicality and reliability of the inkjet printing device 1000.

[0097] See also Figures 5 to 9 The print head 100 proposed in the present application includes a shell 11, a printing module 13 and a cutter module 15. A accommodating cavity is formed in the shell 11. The shell 11 has a printing surface. A first opening 1111a and a second opening 1111b connected to the accommodating cavity are opened on the printing surface. The first opening 1111a and the second opening 1111b are arranged at intervals; the printing module 13 is arranged in the accommodating cavity and is arranged opposite to the first opening 1111a for printing on the printing material; the cutter module 15 is arranged in the accommodating cavity and is arranged opposite to the second opening 1111b for cutting the printing material.

[0098] The housing 11 may be a hollow box structure, which is used to form a housing cavity for placing the printing module 13 and the cutting module 15, so as to isolate and protect the functional modules placed inside the housing 11, thereby improving the protection performance of the print head 100. In some embodiments, the housing 11 may be in a rectangular parallelepiped shape, a cube shape, or other shapes.

[0099] Furthermore, one side of the shell 11 is used to form a printing surface. By opening a first opening 1111a on the printing surface, the printing module 13 in the accommodating cavity can work outward to print a preset image or text on the printing material; a second opening 1111b is also opened on the printing surface, so that the cutter module 15 in the accommodating cavity can work outward to cut the printing material on the printing table. The printing surface can be a plane formed at the bottom end of the shell 11 facing the printing table, and the shape of the first opening 1111a or the second opening 1111b can be a rectangular parallelepiped, a cube or other shapes, which are not limited here. Optionally, the shape of the first opening 1111a can be set to imitate the printing module 13, and the shape of the second opening 1111b can be set to imitate the cutter module 15, so that the shell 11 can be positioned and assembled with the printing module and the cutter 1533 module respectively.

[0100] See also Figures 5 to 10 In an embodiment of the present invention, the cutter module 15 includes a first driving mechanism 151 and a cutter assembly 153. The first driving mechanism 151 is disposed in the accommodating cavity; the cutter assembly 153 is transmission-connected to the first driving mechanism 151 so that the cutter assembly 153 has an extended state in which it at least partially extends out of the second opening 1111b, and a retracted state in which it retracts into the second opening 1111b.

[0101] It should be noted that the inkjet printing device includes a driving device disposed outside the print head 100, and the print head 100 can be in transmission connection with the driving device. During use, the print head 100 can be driven by the driving device to move relative to the printing material to move to a corresponding position of the printing material, and print the printing material and cut the printing material through the printing module 13 or the cutting module 15.

[0102] The printing module 13 can be completely arranged in the accommodating cavity of the shell 11, or a part of it can be arranged in the accommodating cavity and the other part can be arranged outside the accommodating cavity, which is not limited here. The cutter module 15 can be retractably arranged relative to the second port 1111b. When performing the printing step, the printing surface of the print head 100 and the printing material are arranged relative to each other in the vertical direction, that is, they are arranged relative to each other in the third direction. The printing module 13 can perform inkjet printing on the printing material below it, and at the same time, the cutter assembly 153 remains in the retracted state of the second port 1111b to avoid the cutter 1533 from damaging the printing material during the printing process of the print head 100, thereby affecting the processing effect of the print head 100.

[0103] After completing the step of printing the printing material, 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 of at least partially extending from the second port 1111b, so that the printed printing material can be cut by the portion of the cutter assembly 153 extending from the second port 1111b.

[0104] See also Fig.10 and Fig.11 In one embodiment of the present invention, the first driving mechanism 151 includes a rotating portion 1511, one end of which is arranged opposite to the second opening 1111b and connected to the cutter assembly 153, and is used for rotating relative to the second opening 1111b to drive the cutter assembly 153 to rotate toward or away from the second opening 1111b.

[0105] The rotating part 1511 is a mechanism for providing power to the cutter assembly 153 to drive the cutter assembly 153 to rotate toward or away from the second opening 1111b. The rotating part 1511 can provide power in a purely mechanical drive manner or in an electric drive manner. For example, the rotating part 1511 can be, but is not limited to, an electric drive structure such as a rotating motor. The specific selection can be made by those skilled in the art.

[0106] Among them, 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 opening 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.

[0107] See also Fig.12In another embodiment of the present invention, the first driving mechanism 151 includes a translation portion 1513, one end of which is arranged opposite to the second passage 1111b and connected to the cutter assembly 153, and is used for translational movement relative to the second passage 1111b to drive the cutter assembly 153 to move toward or away from the second passage 1111b.

[0108] The translation part 1513 is a mechanism for providing power to the cutter assembly 153 to drive the cutter assembly 153 to move linearly toward or away from the second port 1111b. The translation part 1513 can provide power in a purely mechanical drive manner or in an electric drive manner. For example, the translation part can be, but is not limited to, an electric drive structure such as a linear motor or a linear module. The specific selection can be made by those skilled in the art.

[0109] Among them, the translation part 1513 can be directly connected to the cutter assembly 153 to drive the cutter assembly 153 to translate toward or away from the second opening 1111b; the translation part 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.

[0110] In some embodiments, the translation portion 1513 may specifically include a push member 1513a and a first elastic member 1513b. Specifically, the push member 1513a is movably disposed on one side of the cutter assembly 153 and has an extended position and a retracted position. When the push member 1513a is in the extended position, it is used to abut against the cutter 1533 to drive the cutter assembly 153 to be in the extended state. When the push member 1513a is in the extended position, it is used to disengage from the abutment with the cutter 1533. The first elastic member 1513b elastically connects the cutter assembly 153 and the push member 1513a, and is used to drive the cutter assembly 153 to return to the retracted state when the push member 1513a is in the retracted position.

[0111] Among them, the push member 1513a can be set as an electric drive structure; or, the print head 100 is set to have an ejection stroke moving in the forward direction along the first direction and a reset stroke moving in the reverse direction of the first direction, and the push member 1513a is configured to be movably set along the first direction, for abutting against a collision block outside the print head 100 and moving to an extended position when the print head 100 completes the ejection stroke, so as to drive at least part of the cutter assembly 153 to extend out of the second opening 1111b, or for abutting against another collision block outside the print head 100 and moving to a retracted position when the print head 100 completes the reset stroke, so as to drive the cutter assembly 153 to retract into the second opening 1111b.

[0112] Of course, the technical solution of the present invention is not limited thereto. In some embodiments, the first driving mechanism 151 may include a variety of driving structures, which may be configured as the rotating portion 1511 and the translation portion in the aforementioned embodiment, so that the cutter assembly 153 can rotate or translate relative to the second port 1111b along multiple axis directions under the drive of the first driving mechanism 151, thereby improving the freedom of movement of the cutter assembly 153. The specific implementation method can be set according to actual needs and is not limited here.

[0113] See also Fig.11 In an embodiment of the present invention, the cutter assembly 153 includes a frame 1531 and a cutter 1533. One end of the frame 1531 is transmission-connected to the first driving mechanism 151; the cutter 1533 is disposed at one end of the frame 1531 away from the first driving mechanism 151 and is detachably connected to the frame 1531.

[0114] The frame 1531, as a fixed structure for mounting the cutter 1533, can be connected to the first driving mechanism 151 in a transmission manner, so that the cutter 1533 can be driven to telescopically move relative to the second opening 1111b under the drive of the first driving mechanism 151. Since the cutter 1533 is detachably connected to the frame 1531, and the cutter assembly 153 is arranged opposite to the second opening 1111b, the user can assemble the cutter 1533 to the frame 1531 or disassemble it from the frame 1531 through the second opening 1111b without removing the housing 11, thereby improving the convenience of assembly and disassembly of the cutter 1533.

[0115] In this embodiment, the frame 1531 may also be provided with a limiting groove 1531a, and part of the cutter 1533 can be inserted into the limiting groove 1531a, so that the limiting effect of the limiting groove 1531a on the cutter 1533 can be used to achieve quick positioning of the cutter 1533 and the frame 1531, and the connection stability between the cutter 1533 and the frame 1531 can be improved.

[0116] It should be noted that the cutter 1533 can be detachably connected to the frame 1531 by means of magnetic attraction, or detachably connected to the frame 1531 by means of threaded connection, or detachably installed to the frame 1531 by means of other means. Furthermore, in some embodiments, the cutter 1533 can also be installed to the frame 1531 by means of two or more detachable connection means at the same time. For example, on the basis of the magnetic attraction connection between the cutter 1533 and the frame 1531, the cutter 1533 can be further locked to the frame 1531 by means of a screw structure, so that the connection stability between the frame 1531 and the cutter 1533 can be further improved.

[0117] See also Fig.11In the embodiment of the present invention, the cutter assembly 153 further includes a material pressing piece 1535, which is arranged at one end of the frame 1531 away from the first driving mechanism 151 and protrudes from the frame 1531, and is arranged side by side with the cutter 1533 for pressing the printed material. It can be understood that when the cutter 1533 cuts the printed material, the material pressing piece 1535 can press the printed material from the side of the cutter 1533 through its outer peripheral surface to prevent the printed material from tilting and affecting the printed material cutting effect of the cutter assembly 153. Among them, the material pressing piece 1535 can be a wheel body structure, and its central axis direction is arranged perpendicular to the cutting surface of the cutter 1533; of course, the material pressing piece 1535 can also be set to other shapes, which are not limited here.

[0118] In this embodiment, the side wall of the frame 1531 may be provided with a convex edge structure 1531b, which is provided at one end of the pressing piece 1535 away from the second opening 1111b and is provided around the side of the pressing piece 1535. In this way, the pressing piece 1535 and the frame 1531 can be quickly positioned by the side wall of the edge structure 1531b and the outer peripheral surface of the pressing piece 1535, thereby improving the connection stability between the pressing piece 1535 and the frame 1531. Positioning and limiting between the frame 1531 and the pressing piece 1535 can also be achieved through other limiting structures, such as the cooperation of a positioning hole and a positioning protrusion, etc., which is not limited in this application.

[0119] Further, the pressing piece 1535 can be detachably connected to the frame 1531 to facilitate maintenance or replacement of the pressing piece 1535. Specifically, the pressing piece 1535 can be detachably connected to the frame 1531 by magnetic attraction, or by threaded connection, which is not limited here.

[0120] In a feasible embodiment, the cutter assembly 153 further includes a fastener, which can be set as a screw, and a screw hole can be opened on the frame 1531. The fastener can sequentially penetrate the cutter 1533 and the pressing piece 1535 and be threadedly connected with the frame 1531, that is, the cutter 1533 and the pressing piece 1535 can be locked on the frame 1531 by the same fastener. Of course, the cutter 1533 and the pressing piece 1535 can also be fixedly matched with the frame 1531 by different fasteners, so that the cutter 1533 or the pressing piece 1535 can be disassembled and assembled separately according to the use requirements.

[0121] See also Figures 5 to 9In one embodiment of the present invention, two first openings 1111a are spaced apart on the printing surface, two printing modules 13 are provided, each printing module 13 is provided corresponding to a first opening 1111a, and 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.

[0122] In this embodiment, the inkjet printing device can be a white ink heat transfer printer, and the DTF ink used by it is usually composed of four colors of CMYK ("Cyan Magenta Yellow blacK", printing four-color separation) and white. Correspondingly, the print head 100 is provided with two printing modules 13, one of which is a color ink printing module, which is used to realize the color ink printing function corresponding to the four colors of CMYK; the other printing module 13 is a white ink printing module, which is used to realize the white ink printing function. During use, the print head 100 can first print a color pattern or text on the printing material through one of its printing modules 13, and then print a layer of white ink on the color pattern through another printing module 13. In this way, by printing white ink on the printing material, the color of the printed color pattern or text can be made more vivid.

[0123] Optionally, in one embodiment, the two printing modules 13 are arranged at an interval, and the cutter module 15 can be arranged between the two printing modules 13. During use, after the color ink printing module and the white ink printing module successively complete pattern printing, the cutter module 15 can be switched from a retracted state to an extended state, and moved to a specific position relative to the printed material to cut the printed material.

[0124] In another embodiment, the two printing modules 13 can also be closely arranged, and the cutter module 15 can be arranged on the side of one of the cutter modules 15 away from the other cutter module 15. For example, the color ink printing module, the white ink printing module and the cutter module 15 are arranged in sequence along the printing material transmission direction, that is, they can be arranged in sequence along the second direction, so that the printing material can be connected with the color ink printing module, the white ink printing module and the cutter module 15 in sequence during the transmission process to complete the color ink printing, white ink printing and printing material segmentation steps in sequence. In addition, since the printing material needs to be transferred to a baking machine or a curing machine after completing the steps of printing and printing material segmentation to perform the subsequent printing material drying step, and the inkjet printing device and the baking machine or the curing machine are generally connected in sequence along the printing material transmission direction, the color ink printing module, the white ink printing module and the cutter module 15 are arranged in sequence along the printing material transmission direction, which also facilitates the transfer of the segmented printing material to the baking machine or the curing machine.

[0125] See also Figures 5 to 9In an embodiment of the present invention, the shell 11 includes a main shell 111 and a connecting member 113. The main shell 111 is provided with a accommodating cavity, and a printing surface is formed at one end of the main shell 111; one end of the connecting member 113 is provided on the outer wall of the main shell 111, and the other end extends in a direction away from the main shell 111, and is used for an external driving device to drive the print head 100 to move under the drive of the driving device.

[0126] In this embodiment, the main housing 111 may be provided in an integral structure, which is formed by integral injection molding or integral die casting; or, the main housing 111 may be split into a plurality of housing components and assembled from the plurality of housing components.

[0127] See also Fig. 9 In a feasible embodiment, the main housing 111 includes a bottom shell 1111 and a cover 1113, and a top-opening accommodation space is formed in the bottom shell 1111 for placing components such as a printing module and a cutter 1533 module. The bottom shell 1111 also has a printing surface formed at its bottom end, and a first opening 1111a and a second opening 1111b are provided on the printing surface and are arranged through the bottom wall of the bottom shell 1111. The bottom shell 1111 can be in the shape of a rectangular parallelepiped, a cube or other shapes. The cover 1113 is arranged above the bottom shell 1111, and covers the opening at the top of the bottom shell 1111, and is enclosed with the bottom shell 1111 to form an accommodation cavity. By providing the cover 1113 to cover the opening, the various functional modules placed inside the accommodation cavity can be isolated and protected.

[0128] The connecting member 113 is a plate structure, one end of which is connected to the outer wall of the main housing 111, specifically, it can be fixedly connected to the outer wall of the bottom shell 1111, or it can be fixedly connected to the outer part of the cover body 1113, and the other end protrudes toward the side of the main housing 111. By connecting the connecting member 113 to an external drive device, the drive device can drive the connecting member 113 to drive the print head 100 to move relative to the printing material as a whole, so that the print head 100 can process different positions of the printing material. Furthermore, the connecting member 113 also has a bearing surface 1131 formed on the top thereof, so that the connecting member 113 can play a role in connecting with the external drive device, and can also play a role in supporting some components of the print head 100.

[0129] See also Figure 6 and Figure 7In an embodiment of the present invention, the print head 100 further includes a main board 17, which is disposed in the accommodating cavity and connected to a cavity wall on one side of the accommodating cavity facing the connecting member 113; the main shell 111 includes a heat dissipation portion 1111c, which is located on a side of the main shell 111 facing the connecting member 113 and is arranged to avoid the connecting member 113, and at least a portion of the main board 17 abuts against the heat dissipation portion 1111c to dissipate heat through the heat dissipation portion 1111c.

[0130] Among them, the main shell 111 can be connected to a heat sink on its outer wall to form a heat sink 1111c, and the heat sink can be but is not limited to being set as a heat sink; the main shell 111 can also be provided with a plurality of array-arranged protrusion structures on the side away from the main board 17, so that heat sink fins can be formed through the main shell 111's own structure, thereby forming the heat sink 1111c of the main shell 111.

[0131] Furthermore, at least part of the connecting member 113 is flush with the heat dissipation portion 1111c in height. On this basis, an avoidance groove can be provided in the area corresponding to the heat dissipation portion 1111c on the side of the connecting member 113 facing the main housing 111, and the heat dissipation portion 1111c is provided in the avoidance groove, so that the heat dissipation portion 1111c and the connecting member 113 can be arranged to avoid each other. Of course, the heat dissipation portion 1111c and the connecting member 113 can also be arranged to be staggered in the height direction to achieve mutual avoidance between the heat dissipation portion 1111c and the connecting member 113, which is not limited here.

[0132] Further, in order to improve the heat dissipation effect, the main housing 111 is further provided with heat dissipation holes 1111d in the area corresponding to the mainboard 17. Figure 5 One or more heat dissipation holes 1111d may be provided at the positions of the main housing 111 on both sides corresponding to the mainboard 17. The heat dissipation holes 1111d are connected to the accommodating cavity in the main housing 111 to ventilate and dissipate heat for the mainboard 17 and other components in the accommodating cavity.

[0133] See also Figures 5 to 9 In an embodiment of the present invention, the shell 11 also includes a mounting member 115, one end of the mounting member 115 is arranged on a side of the main shell 111 away from the connecting member 113, and the other end extends in a direction away from the main shell 111; the print head 100 also includes a camera module 18, and the camera module 18 is installed on the mounting member 115.

[0134] It can be understood that by setting a camera module 18 on the print head 100 to photograph 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 the printing position of the print head 100 can be further calibrated based on the detection result, which is beneficial to ensure the printing quality of the print head 100.

[0135] In one embodiment of the present application, the mounting member 115 and the connecting member 113 are arranged on opposite sides of the main housing 111, and the connecting member 113 is connected to an external driving device in a transmission manner. The external driving device can be arranged inside the housing of the inkjet printing device, for example, behind the print head 100, and the external driving device can drive the print head 100 to move in a translational direction perpendicular to the arrangement direction of the mounting member 115 and the connecting member 113. This arrangement can reduce the volume of the print head 100 in a direction perpendicular to the arrangement direction of the mounting member 115 and the connecting member 113, so that the print head 100 can have sufficient transfer space. Of course, the present application is not limited to this. In other embodiments, the driving device can also be connected to the main housing 111 or the mounting member 115 in a transmission manner, so as to drive the print head 100 to move in a translational direction perpendicular to the arrangement direction of the mounting member 115 and the connecting member 113.

[0136] The mounting member 115 may be a box structure with a hollow interior, in which an inner cavity for accommodating the camera module 18 is formed, and the inner cavity can be connected to the accommodating cavity of the main housing 111, and the outer wall of the mounting member 115 is provided with a through hole connected to the inner cavity, so that the camera module 18 can shoot and detect outward through the through hole; or, the mounting member 115 may also be a plate structure for fixing and connecting the camera module 18, and the camera module 18 may be fixed to the bottom of the plate structure. The mounting member 115 may be separated from the main housing 111, or the mounting member 115 and the main housing 111 may be integrated, thereby improving the stability of the overall structure of the print head 100.

[0137] In an embodiment of the present invention, at least part of the main housing 111 is made of plastic material. It should be noted that in the related art, the material of the housing 11 of the print head 100 is usually set to sheet metal material. In comparison, the technical solution of the present invention is conducive to reducing the weight of the housing 11 by making at least part of the main housing 111 of plastic material, so that the external drive device drives the print head 100, so that the speed adjustment of the print head 100 can have more margin. In addition, the selection of plastic material is also conducive to reducing the preparation cost of the housing 11.

[0138] In the embodiment of the present invention, the connecting member 113 is made of sheet metal material. In the inkjet printing device, the print head 100 is connected to the external driving device through the connecting member 113 of the housing 11, so that the overall weight of the print head 100 is mainly supported by the connecting member 113. By setting the material of the connecting member 113 to sheet metal material, the structural strength of the connecting member 113 can be guaranteed, thereby ensuring the structural stability of the inkjet printing device.

[0139] See also Figure 13 to Figure 14In some embodiments, the printing module 13 includes an inkjet mechanism 131, an ink storage mechanism 133, and a leak prevention mechanism (not shown). The inkjet mechanism 131 is disposed at the first port 1111a; the ink storage mechanism 133 is detachably connected to the inkjet mechanism 131 to deliver ink to the inkjet mechanism 131; the leak prevention mechanism is connected between the inkjet mechanism 131 and the ink storage mechanism 133 to prevent the ink in the ink storage mechanism 133 from leaking out when the ink storage mechanism 133 and the inkjet mechanism 131 are separated. The inkjet mechanism 131 is used to eject ink.

[0140] The ink storage mechanism 133 may be a color ink supply mechanism such as a color ink bag, or a white ink supply mechanism such as a white ink bag. The inkjet mechanism 131 may be configured as a nozzle for printing the ink provided by the ink bag on the printing material in an inkjet printing manner.

[0141] In one embodiment of the present application, the ink storage mechanism 133 and the inkjet mechanism 131 can be connected by plug-in cooperation, so that the ink storage mechanism 133 and the inkjet mechanism 131 can be quickly plugged in and out, thereby improving the convenience of assembling the printing module 13. Of course, the ink storage mechanism 133 and the inkjet mechanism 131 can also be detachably connected by snap connection, thread connection, or other methods, which are not limited here. In addition, the ink storage mechanism 133 can be connected to the ink supply module 300 pipeline, 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.

[0142] It should be noted that in a printing module 13, a plurality of ink storage mechanisms 133 may be provided, and the plurality of ink storage mechanisms 133 are connected side by side to the inkjet mechanism 131. In order to improve the connection stability between the ink storage mechanism 133 and the inkjet mechanism 131, the inkjet mechanism 131 may be provided with a plurality of positioning grooves 1311, the shape of the positioning grooves 1311 is configured to imitate the inkjet mechanism 131, and each positioning groove 1311 is used to cooperate with an inkjet mechanism 131 in limiting position. Of course, the inkjet mechanism 131 may also limit the ink storage mechanism 133 by other positioning structures, which is not limited here.

[0143] The ink storage mechanism 133 is detachably connected to the inkjet mechanism 131, that is, after the ink storage mechanism 133 is installed on the inkjet mechanism 131, it can be separated and removed to facilitate the maintenance and replacement of various structures of the printing module 13. On this basis, by connecting the anti-leakage mechanism between the inkjet mechanism 131 and the ink storage mechanism 133, it can be prevented that when the anti-leakage mechanism is removed from the inkjet mechanism 131, the ink in the ink storage mechanism 133 leaks outward and directly enters the accommodating cavity, causing contamination to other structures of the print head 100.

[0144] Among them, the leakage prevention mechanism can be specifically configured as a leakage prevention valve. When the ink storage mechanism 133 is connected to the inkjet mechanism 131, the leakage prevention valve opens to connect the ink paths of the ink storage mechanism 133 and the inkjet mechanism 131; when the ink storage mechanism 133 is separated from the inkjet mechanism 131, the leakage prevention valve closes to stop the ink storage mechanism 133 from discharging ink.

[0145] In a feasible embodiment, the inkjet printing device can be a white ink heat transfer printer. Correspondingly, among the two printing modules 13 of the print head 100, one of the printing modules 13 is provided with four ink storage mechanisms 133, which are specifically configured as four color ink capsules corresponding to the four colors of CMYK; the other printing module 13 can also be provided with four ink storage mechanisms 133, and the four ink storage mechanisms 133 are all white ink capsules. During use, the print head 100 can first print a color pattern on the printing material through one of the printing modules 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 color of the printed color pattern can be made more vivid.

[0146] Furthermore, in some embodiments, when the four ink storage mechanisms 133 in the printing module 13 are all white ink capsules, the four white ink capsules can be designed as a four-in-one structure, that is, the four white ink capsules are connected to form an integrated structure. In this way, the four white ink capsules can be disassembled and assembled with the inkjet mechanism 131 as a whole, which is conducive to improving the structural integration and disassembly convenience of the printing module 13.

[0147] See also Figure 6 and Fig.13 In some embodiments, the printing module 13 further includes an adapter plate 134, which can be electrically connected to the inkjet mechanism 131, and the input interface of the adapter plate 134 can be connected to the main board 17, and the adapter plate 134 can be connected to multiple nozzles in the inkjet structure 131 (such as Fig.13 4 of them), and then when assembling the printing module 13, only one flat cable is needed to connect the main board 17 and the adapter board 134 together, without setting multiple flat cables to connect the main board and multiple nozzles, which makes wiring more convenient and assembly simpler.

[0148] See also Figure 6 and Figure 7 In the embodiment of the present invention, the print head 100 further includes an anti-collision mechanism 19, which is disposed on the housing 11 and is used to prevent the housing 11 from being subjected to external collision. It can be understood that by arranging the anti-collision mechanism 19 on the print head 100 to prevent the housing 11 from being subjected to external collision, the safety of the print head 100 can be improved.

[0149] Among them, the anti-collision mechanism 19 can be set on the side of the shell 11 to prevent the outer wall of the print head 100 from colliding with the external structure. For example, the print head 100 can move in the first direction, and the anti-collision mechanism 19 can be set on the opposite sides of the print head 100 along the first direction, so as to avoid the risk of the shell 11 being hit by the outside when the print head 100 moves in the first direction; or, the anti-collision mechanism 19 can also be set at the bottom of the shell 11 to prevent the printing surface at the bottom of the print head 100 from colliding with the external structure, and thereby achieve the effect of preventing the hand from being pinched; or, the anti-collision mechanism 19 can also be set on the side and bottom of the shell 11, so as to improve the comprehensiveness of the protection of the print head 100. Of course, the anti-collision mechanism 19 can also be used to realize the anti-collision function of other positions of the shell 11; the number of anti-collision mechanisms 19 provided on the shell 11 can be one, or two or more. That is, the present application does not limit the setting position and number of the anti-collision mechanism 19.

[0150] Furthermore, when the anti-collision mechanism 19 is provided on the side and the bottom of the shell 11, the anti-collision mechanism 19 provided on the side and the bottom of the shell 11 can be integrated into one, which is helpful to reduce the number of parts on the print head 100, so as to improve the structural integration and assembly efficiency of the print head 100.

[0151] In one embodiment, the anti-collision mechanism 19 can be specifically arranged on the housing 11 of the print head 100, and at least partially protrude from the outer surface of the housing 11. In this way, during the movement of the print head 100, the anti-collision mechanism 19 can detect whether it is in contact with an external structure by means of contact detection. For example, the anti-collision mechanism 19 can be configured as a pressure sensor or other contact detection mechanism. Since the anti-collision mechanism 19 protrudes from the outer surface of the housing 11, it can contact the external structure before the housing 11, so that the housing 11 can be braked in time when the anti-collision mechanism 19 is triggered to avoid excessive movement of the housing 11 and collision with the external structure.

[0152] Alternatively, in another embodiment, the anti-collision mechanism 19 can also detect the distance between it and the external structure by non-contact detection. For example, the anti-collision mechanism 19 can be configured as an infrared distance 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 to avoid excessive movement of the housing 11 and collision with the external structure. The specific configuration can be as needed and is not limited here.

[0153] See also Fig.16 and Fig. 20In some embodiments of the present application, the inkjet printing device 1000 also includes a negative pressure module 29, an adsorption chamber 21 is provided in the printing table 200, a vacuum hole 24 connected to the adsorption chamber 21 is provided on the surface of the printing table 200, and the negative pressure module 29 is arranged in the adsorption chamber 21.

[0154] In this embodiment, a certain space of adsorption chamber 21 can be formed in the printing table 200. By using the negative pressure module 29 to operate in the adsorption chamber 21, a certain vacuum negative pressure environment can be formed in the adsorption chamber 21, so that the printing material placed on the surface of the printing table 200 can be subjected to the negative pressure at the vacuum hole 24, so that the printing material can be stably adsorbed on the surface of the printing table 200 for printing processing, preventing the printing material from shifting during the processing, reducing printing waste, and ensuring the accurate printing effect of the inkjet printing device 1000. Among them, the negative pressure module 29 can adopt various types of structures, such as axial flow fans, centrifugal fans, etc., and the application does not limit the type of negative pressure module 29, and it can extract the air in the adsorption chamber 21 to form a certain negative pressure environment. In addition, a single negative pressure module 29 can be set in the adsorption chamber 21, or multiple negative pressure modules 29 can be arranged in the adsorption chamber 21 to increase the rate of forming the negative pressure environment. The application does not specifically limit the number of negative pressure modules 29.

[0155] Furthermore, in one embodiment, the adsorption chamber 21 can be arranged in a flat shape, and the negative pressure module 29 can be arranged in a structure of a centrifugal fan. It is understandable that the centrifugal fan has a small height and can be more conveniently arranged in the flat adsorption chamber 21, which is conducive to better reducing the height of the printing table 200, reducing the space occupied by the bearing assembly in the body, and realizing a better spatial layout of various components in the inkjet printing device 1000.

[0156] See also Figures 16 to 18 In some embodiments of the present application, the printing table 200 has a relative feed side and a discharge side, and the inkjet printing device 1000 also includes a feeding mechanism 22, which is arranged on the feed side of the printing table 200 or integrated in the printing table 200.

[0157] In this embodiment, the printing material can be transported from the feed side of the printing table 200 to the surface of the printing table 200 for printing processing, and output from the discharge side of the printing table 200 after the processing operation is completed on the printing table 200. By setting a feeding mechanism 22 on the feed side of the printing table 200, the feeding mechanism 22 can be used to play a certain transmission role on the printing material, so that the printing material can stably move from the feed side to the discharge side, and realize the continuous automatic feeding operation of the inkjet printing device 1000. For ease of understanding and explanation, all are based on Fig.16The directions indicated by the coordinate system shown in are for reference, wherein 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 of the x-axis is left; the positive direction of the y-axis is front, and the negative direction of the y-axis is back; the positive direction of the z-axis is up, and the negative direction of the z-axis is down. The feed side and the discharge side of the printing table 200 may be opposite sides along the second direction, so that the printing material moves under the transmission action of the feeding mechanism 22, that is, the printing material can be driven along the first direction for feeding and printing, and at this time, the print head 100 can be moved along the second direction, and then the transmission efficiency of the feeding mechanism 22 and the moving speed of the print head 100 can be adjusted to achieve accurate printing of the print head 100.

[0158] In some embodiments, the feeding mechanism 22 may include a bracket fixedly mounted on the feed side of the printing table 200, a rotating shaft 221 rotatably mounted on the bracket, and a roller 223 sleeved on the rotating shaft 221. The rotating shaft 221 may be driven to rotate by a driving member such as a motor. By driving the roller 223 to rotate by the rotating shaft 221, the roller 223 may be brought into contact with the printing material placed on the feed side of the printing table 200, and the printing material may be transmitted along the second direction under the friction force between the roller 223 and the printing material, thereby achieving stable feeding of the inkjet printing device 1000. Of course, the present application is not limited thereto. In other embodiments, the feeding mechanism 22 may also adopt a conveyor belt structure. The present application does not limit the structural shape of the feeding mechanism 22, and it only needs to be able to achieve the transmission of the printing material.

[0159] Also, see Fig.18 and Fig.19 In some embodiments of the present application, a limiting plate 25 extending along the second direction may be provided on the surface of the printing table 200. The limiting plate 25 is arranged opposite to the surface of the printing table 200 and is spaced apart from the printing table 200 to form a conveying groove 251, and the edge of the printing material is clamped in the conveying groove 251. It can be understood that the limiting plate 25 can be connected to the surface of the printing table 200 by bending the side along the first direction, or the limiting plate 25 can be formed by bending the side of the printing table 200 upward, so that the limiting plate 25 and the printing table 200 are integrally formed. The present application does not limit the shape of the limiting plate 25. By using the limiting plate 25 to form the conveying groove 251 on the printing table 200 at intervals, the edge of the printing material can be clamped in the conveying groove 251 when the printing material is conveyed along the second direction, so that the limiting plate 25 can play a certain limiting role in the conveying of the printing material, effectively preventing the printing material from being offset during the conveying and having a certain probability of affecting the printing effect, and realizing the precise printing processing of the inkjet printing device 1000.

[0160] See also Fig.17In some embodiments of the present application, the inkjet printing device 1000 further includes a material 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 .

[0161] It can be understood 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 be better close to the surface of the printing table 200 for printing processing, thereby reducing the defective rate of the printed material after processing and further improving the reliability of the inkjet printing device 1000.

[0162] See also Fig.17 In some embodiments, the material pressing mechanism 23 may include a second driving mechanism 231 and a pressing wheel 233. The second driving 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. The transmission rod 2313 is rotatably connected to the first support frame 2311, and the handle 2315 is connected to one end of the transmission rod. The pressing wheel 233 is sleeved and installed 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, so that the cam surface on the transmission rod 2313 abuts and drives the pressing wheel 233 to move toward the direction of the printing table 200, so that the pressing wheel 233 presses the printing material; and the pressing wheel 233 can be With a second elastic member such as a spring or a rubber pad, when the second driving mechanism 231 drives the pressing wheel 233 to press and move downward, the second elastic member in the pressing wheel 233 can be in a certain elastic deformation state, and then when it is necessary to release the pressing effect of the pressing wheel 233 on the printing material to take and place the printing material, the handle 2315 can be operated in the opposite direction to make the plane on the transmission rod 2313 contact the pressing wheel 233, and at this time, the second elastic member in the pressing wheel 233 is released from the force and restores the elastic deformation, so that the pressing wheel 233 is reset away from the printing table 200, thereby realizing the stable pressing and avoiding of the printing material by the pressing wheel 233 mechanism, ensuring the stable printing processing and taking and placing of the printing material on the printing table 200, and further improving the practicality and reliability of the inkjet printing device 1000. Of course, the present application is not limited to this. In other embodiments, the pressing mechanism 23 can also adopt the structure of the lifting and lowering pressure block. The present application does not limit the structure of the pressing mechanism 23, and it can achieve the pressing of the printing material on the printing table 200.

[0163] Among them, when the inkjet printing device 1000 is also provided with a feeding mechanism 22 to transport the printing material, the pressing mechanism 23 can be at least partially located above the feeding mechanism 22, so that the pressing mechanism 23 can press the printing material onto the feeding mechanism 22 to ensure the contact between the printing material and the feeding mechanism 22, so that the feeding mechanism 22 can more stably transport the printing material to the surface of the printing table 200.

[0164] See also Fig.18 and Fig.19 In some embodiments of the present application, a material detection mechanism 271 may be installed on the printing table 200, and the material detection mechanism 271 may be used to detect whether there is printing material on the printing table 200, and then the information detected by the material detection mechanism 271 may be transmitted to the controller of the inkjet printing device 1000, and the print head 100 may be started to perform the printing operation after the printing material is identified to be placed on the printing table 200, so as to prevent the print head 100 from directly spraying ink onto the printing table 200. In addition, by using the material detection mechanism 271 to detect whether there is printing material on the printing table 200, it is also possible to feedback whether the printing material is loaded successfully, so as to realize the fault detection of the inkjet printing device 1000, and further improve the practicality and reliability of the inkjet printing device 1000.

[0165] For further information, see Fig.21 and Fig. 22 A detection slot 27 may be provided on the printing table 200, and a material detection mechanism 271 may be accommodated in the detection slot 27, so that the material detection mechanism 271 may identify the printing material on the surface of the printing table 200 through the notch of the detection slot 27, which is helpful 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 transmitted on the printing table 200 more smoothly. At this time, the material detection mechanism 271 may include a signal transmitter and a signal receiver. The signal transmitter may 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 and reflected, so that the signal receiver cannot receive the detection light emitted by the signal reflection part, and the signal receiver may send a signal to the controller that the printing material is not placed; and when printing material is placed on the surface of the printing table 200, the printing material covers the notch of the detection slot 27, so that the detection light reflected by the signal reflection part is blocked and reflected by the printing material, and then the signal receiver may receive the light emitted by the signal transmitter, so that the signal receiver may send a signal to the controller that the printing material has been placed. Of course, the present 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. The present application does not limit the type of the material detection mechanism 271, and it is sufficient to detect whether there is printing material on the printing table 200.

[0166] See also Figure 4 , Fig.16 and Fig.21In some embodiments of the present application, the inkjet printing device 1000 includes a moving device 600, which is disposed above the printing table 200 or on a side of the printing table 200 and is connected to the print head 100 to drive the print head 100 to move on the printing table 200.

[0167] For further information, see Figure 21 to Figure 23 In some embodiments, the mobile device 600 includes a second support frame 61 and a driving mechanism 63. The second support frame 61 is arranged on the base of the housing 700; the driving mechanism 63 is connected to the second support frame 61, and the print head 100 is connected to the driving mechanism 63 and can move relative to the second support frame 61. The driving mechanism 63 drives the print head 100 to move back and forth along the first direction.

[0168] For ease of understanding and explanation, Fig.16 The directions indicated by the coordinate system shown in are for reference, wherein 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 of the x-axis is left; the positive direction of the y-axis is front, and the negative direction of the y-axis is back; the positive direction of the z-axis is up, and the negative direction of the z-axis is down. In this embodiment, the second support frame 61 can be formed by processing steel with a certain structural strength. Of course, it can also be formed by overlapping a pipe structure. There are many kinds of structural materials and shapes of the second support frame 61, which can play a certain supporting role, and this application does not limit this. The drive mechanism 63 can be a transmission method using a synchronous belt (i.e., a combination of a pulley and a belt), and of course, it can also be a transmission method using a chain drive (i.e., a combination of a sprocket and a chain). This application does not limit the transmission method of the drive mechanism 63, and 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 body. The driving mechanism 63 is used to drive 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 reciprocated according to a certain moving path, so that the print head 100 can spray ink on the printing material to form the desired image or text.

[0169] For further information, see Fig.21 The moving device 600 further includes a support rail 65 and a support slider 67. The support rail 65 is arranged on the second support frame 61 and extends along the first direction, and can be arranged side by side with the driving 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 rigid support effect can be provided to the print head 100, which is conducive to sharing part of the force of the print head 100, reducing the load-bearing requirement of the driving mechanism 63, and better improving the service life of the driving mechanism 63.

[0170] For further information, see Fig.21 and Fig.23 The driving mechanism 63 includes a third driving mechanism, a driving wheel 633, a driven wheel 635 and a transmission belt 637. The driving wheel 633 and the driven wheel 635 are drivably arranged on the second support frame 61. The transmission belt 637 connects the driving wheel 633 and the driven wheel 635. The third driving mechanism is connected to the second support frame 61 and drives the driving wheel 633 to rotate, so that the driving wheel 633 drives the transmission belt 637 and the driven wheel 635 to rotate. The third driving mechanism can use a motor, and of course other devices that drive the driving wheel 633 to rotate can also be used, which is not limited in this application. 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 the first direction following the clamp 6371. The chuck 6371 includes a bottom plate 6371a and two relative clamping blocks 6371b, a clamping groove is formed between the two relative clamping blocks 6371b, and the two ends of the belt body 6373 are respectively inserted into the clamping groove from the opposite sides of the chuck 6371. The two relative clamping blocks 6371b can be relatively movable, so that the chuck 6371 clamps the two ends of the belt body 6373, so that the belt body 6373 and the chuck 6371 are enclosed to form a ring. Then, the chuck 6371 is used to clamp the two ends of the belt body 6373 to form a ring-shaped transmission belt 637, so that the transmission belt 637 can be more conveniently adjusted in overall length, so that the transmission belt 637 can be better adapted to various types of driving mechanisms 63. The relative surfaces of the two clamping blocks 6371b can be provided with a protruding structure such as meshing teeth, so that the chuck 6371 can better utilize the protruding structure to mesh and clamp the belt body 6373, thereby improving the structural stability and reliability of the transmission belt 637. In addition, for example, the clamping block 6371b can be connected to the base plate 6371a by means of screw connection. At this time, 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 making the two relatively clamping blocks 6371b close to each other and clamping the belt body 6373; of course, the clamping block 6371b and the base plate 6371a can also be connected by means of snaps, etc., so as to realize the connection of the clamping block 6371b on the base plate 6371a and the clamping belt body 6373, and the present application does not limit this.

[0171] For further information, see Fig.21 and Fig. 22The driving mechanism 63 also includes a tensioning mechanism 639, which is used to adjust the distance between the driven wheel 635 and the driving wheel 633. Exemplarily, in some embodiments, the tensioning mechanism 639 may include an adjusting plate 6391, an adjusting bolt 6393 and a third elastic member 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 a bolt hole, and the adjusting bolt 6393 is connected to the bolt hole. The third elastic member 6395 is connected to the adjusting bolt 6393 and abuts against the driven wheel 635. The third elastic member 6395 may be a spring, or may be rubber, etc. The present application does not limit the type of the third elastic member 6395. Further, by tightening or loosening the adjusting bolt 6393 on the adjusting plate 6391, the elastic deformation of the third elastic member 6395 may be changed, thereby adjusting the distance between the driven wheel 635 and the driving wheel 633, thereby realizing the tension adjustment of the transmission belt 637, so that the driving mechanism 63 can more stably drive the print head 100 to reciprocate along the first direction. Of course, the present application is not limited to this. In other embodiments, the tensioning mechanism 639 can also adopt a sliding structure that connects and supports the driven wheel 635. The present application does not limit the tensioning mechanism 639, and it only needs to be able to adjust the distance between the driven wheel 635 and the driving wheel 633.

[0172] See also Fig.15 and Fig.24 In some embodiments of the present application, the ink supply module 300 includes an ink cartridge 31 and an ink supply pipeline 33 , and the ink supply pipeline 33 connects the ink cartridge 31 and the printing module 13 of the print head 100 .

[0173] It can be understood that the ink cartridge 31 can be a storage container that can store a certain volume of ink. By utilizing the ink supply pipe 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 pipe layout, so that the inkjet printing device 1000 can achieve a more reasonable structural design.

[0174] Among them, see Fig.15 and Fig.24The ink supply module 300 may be provided 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 use different ink combinations to achieve multiple colors of inkjet effects, so that the inkjet printing device 1000 can better process and form the required image or text on the printing material. At this time, at least two ink cartridges 31 can be arranged in sequence and connected to form a whole, which is convenient for the disassembly and assembly of the ink cartridges 31. A sequentially matching disassembly and assembly structure can be provided between at least two ink cartridges 31, so that at least two ink cartridges 31 can only be removed in a certain order of placement; of course, the ink supply module 300 can also use a fixed frame to load at least two ink cartridges 31, so that the ink cartridges 31 are arranged on the fixed frame in a certain order. The present application does not limit the assembly method of the ink cartridges 31. In addition, the ink supply module 300 can be provided with at least two ink supply pipes 33 , so that one ink supply pipe 33 is connected to one ink cartridge 31 , thereby ensuring stable and independent ink supply to multiple ink cartridges 31 and ensuring stable operation of the inkjet printing device 1000 .

[0175] It is understandable that the ink supply module 300 can set the ink cartridge 31 outside the inkjet printing device 1000, and use the ink supply pipeline to connect the ink cartridge 31 and the print head 100 for ink supply; or, when the inkjet printing device 1000 is provided with a housing 700 to accommodate multiple components, the ink supply module 300 can also be set in the receiving space of the housing 700, so that the inkjet printing device 1000 can integrate multiple components in the housing 700, which is convenient for the aesthetics of the inkjet printing device 1000 and the compact design of the whole machine. Of course, the present application does not limit the setting method of the ink supply module 300, and it is sufficient to achieve the stable setting of the ink supply module 300 and the supply of ink between the ink supply module 300 and the print head 100.

[0176] For example, see Fig.15 In some embodiments, when the ink supply module 300 is disposed in the housing 700, the housing 700 may be provided with a third support frame 76 behind the print head 100, so that the ink cartridge 31 of the ink supply module 300 may be stably arranged and mounted on the third support frame 76. Then, the ink supply line 33 is stably routed in the housing 700 to achieve stable connection and ink supply between the ink cartridge 31 and the print head 100. The ink supply line 33 may be connected with a filter 331 and a pump 333 in sequence, and the pump 333 is used to generate a suction force on the ink supply line 33, so that the ink material may pass through the filter 331 and the pump 333 in sequence and then flow into the print module 13 of the print head 100, which is conducive to reducing the blockage of the print module 13 caused by impurities in the ink material, and ensuring stable jet printing of the print module 13. The filter 331 and the pump 333 can be installed in the housing 700, and a plurality of pipe sections can be used to sequentially connect the ink cartridge 31, the filter 331, the pump 333 and the printing module 13 to achieve a more compact structural layout of the inkjet printing device 1000.

[0177] For further information, see Fig.26 The ink cartridge 31 may be provided with an ink detection device 311, which can be used to detect the amount of ink in the ink cartridge 31. Exemplarily, the ink detection device 311 may include a first detection float 3111 disposed in the ink cartridge 31 and a first detection signaler 3113 disposed outside the ink cartridge 31. The first detection float 3111 may move up and down with the liquid level in the ink cartridge 31, and then the first detection signaler 3113 may be triggered when the first detection float 3111 moves to a certain height, so that the first detection signaler 3113 sends a signal indicating a lack of ink or full ink to the controller of the inkjet printing device 1000, reminding the user to add ink to the ink cartridge 31 or stop filling ink. The first detection signaler 3113 may be a Hall sensor, and a trigger structure 47 such as a magnet may be provided in the first detection float 3111, so that the first detection signaler 3113 may be triggered when the first detection float 3111 rises and falls to a position relative to the first detection signaler 3113. Of course, the ink detection device 311 can also adopt detection devices such as pressure sensitive sensors, and this application does not limit this.

[0178] In addition, a guide structure 319 for guiding and limiting the lifting and lowering movement of the first detection float 3111 may be provided in the ink cartridge 31, so that the first detection float 3111 can be vertically lifted and lowered along a third direction to prevent the first detection float 3111 from leaving the detection range of the first detection signal device 3113.

[0179] See also Fig.25 In some embodiments, the ink cartridge 31 may include a first ink cartridge 313 and a second ink cartridge 315, and a stirring mechanism 35 is provided in the first ink cartridge 313. When the inkjet printing device 1000 prints on a printing material such as a film material, it is usually possible to complete the spraying of colored inks and then spray white ink as the base color of the printing material. At this time, the first ink cartridge 313 can be used to store white ink, and the second ink cartridge 315 can be used to store colored inks. Of course, the present 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 inks to ensure the printing function of the inkjet printing device 1000. When loading inks such as white ink that are easy to condense in the first ink cartridge 313, the ink in the first ink cartridge 313 can be stirred by using the stirring mechanism 35, so that the ink in the first ink cartridge 313 can be effectively prevented from condensing, and the fluidity of the ink in the first ink cartridge 313 can be ensured.

[0180] For further information, see Fig.25In some embodiments, the stirring mechanism 35 includes a stirring blade 351 and a stirring motor 353. The stirring blade 351 is rotatably arranged in the first ink cartridge 313. The stirring motor 353 is arranged 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 to connect the stirring blade 351. The stirring motor 353 is arranged on the first ink cartridge 313 to drive the stirring blade 351 in the first ink cartridge 313 to rotate. It is not necessary to dismantle the stirring mechanism 35 on the first ink cartridge 313 for maintenance, reducing the opening structure of the first ink cartridge 313 for disassembling the stirring mechanism 35 and reducing the ink leakage of the first ink cartridge 313. Of course, in other embodiments, the stirring mechanism 35 can also adopt ultrasonic vibration. The present application does not limit the type of the stirring mechanism 35. It only needs to be able to stir the ink in the first ink cartridge 313.

[0181] In addition, the first ink cartridge 313 may be provided with a first ink outlet and a second ink outlet, one end of the ink supply line 33 is connected to the first ink outlet, and an ink return branch is provided on the ink supply line 33, and the ink return branch is connected to the second ink outlet. The ink supply line 33 can draw out the ink in the first ink cartridge 313 through the first ink outlet, and by providing the ink return branch on the ink supply line 33, part of the ink in the first ink cartridge 313 can be circulated through the ink supply line 33, which is conducive to preventing the ink in the first ink cartridge 313 from being left still and condensing with a certain probability, and further ensuring the fluidity of the ink in the ink supply module 300.

[0182] In some embodiments, see Fig.15 The housing 700 also includes a drag chain structure 77, which is movably arranged. A pipe channel is arranged in the drag chain structure 77, and the ink supply pipeline 33 is arranged through the pipe channel.

[0183] In this embodiment, the ink supply pipeline 33 is routed through the drag chain structure 77, and the drag chain structure 77 can be used to bind multiple pipelines to form a whole, so as to achieve a regular arrangement of the ink supply pipeline 33 in the housing 700, reduce the interference between the ink supply pipeline 33 and other components in the housing 700, and better achieve a compact design of the inkjet printing device 1000. The drag chain structure 77 can also make the ink supply pipeline 33 move more stably with the print head 100, reduce the drag force of the ink supply pipeline 33, and better avoid leakage between the ink supply module 300 and the printing module 13.

[0184] See also Figure 4 , Fig.16 and Fig. 27 In some embodiments of the present application, the inkjet printing device 1000 further includes an ink stack module 400 , and the ink stack module 400 is used to clean and / or moisturize the printing module 13 of the print head 100 .

[0185] In this embodiment, the ink stack module 400 can be used to clean and / or moisturize the printing module 13, which is helpful to avoid the condensation of ink at the nozzle of the printing module 13 and blockage of the nozzle, and ensure the stable operation of the print head 100. Among them, there are multiple ways for the ink stack module 400 to clean the printing module 13, such as scraping to remove the condensed ink on the printing module 13, or using a detergent to clean the printing module 13. Of course, it can also be a combination of multiple cleaning methods, such as scraping first and then cleaning. The present application does not limit the cleaning method of the ink stack module 400, and it is sufficient to be able to clean the printing module 13 with the ink stack module 400.

[0186] The ink stack module 400 can be set on one side of the printing table 200 along the first direction, so that the print head 100 can be more conveniently moved from the printing table 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.

[0187] For further information, see Fig. 27 and Fig.28 The ink stack module 400 may have a cleaning surface. The ink stack module 400 includes a trigger structure 47 . The trigger structure 47 is disposed on the cleaning surface. The trigger structure 47 is used to detect and position the print head 100 .

[0188] Exemplarily, the trigger structure 47 can be a convex structure arranged on the cleaning surface. By arranging a groove at the corresponding position of the printing module 13, the print head 100 can be located above the ink stack module 400, and the cleaning structure of the ink stack module 400 is in contact with the printing module 13, so that the convex structure is inserted into the groove. At this time, a corresponding triggering sensor can be arranged in the convex structure or the groove, so that the controller of the inkjet printing device 1000 can know that the print head 100 is correspondingly arranged on the ink stack module 400. At this time, the ink stack module 400 can be stably started to clean the printing module 13, so as to achieve accurate 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 a certain probability of the ink stack module 400 idling or leaking due to the offset of the print head 100 from the ink stack module 400, so as to ensure accurate cleaning of the print head 100 by the ink stack module 400. Of course, in other embodiments, the trigger structure 47 can also use a pressure-sensitive sensor, a distance-measuring sensor, etc. The present application does not limit the type of the trigger structure 47 , as long as it can achieve corresponding detection between the print head 100 and the ink stack module 400 .

[0189] See also Fig. 27 and Fig.28In some embodiments, the ink stack module 400 may include an ink stack table 41 and an ink pad 42. The top surface of the ink stack table 41 is provided with a dirt collection groove 411, and the ink pad 42 is arranged in the dirt collection groove 411. At this time, when the print head 100 is placed on the ink stack module 400 for cleaning, the print module 13 can be in contact with the ink pad 42. The ink pad 42 can be a cleaning pad with a certain function of absorbing and condensing ink, or can be a cleaning pad with a certain function of wiping condensed ink, etc. The present application does not limit the type of the ink pad 42, and it can achieve the cleaning function of the print module 13. With the ink pad 42 arranged in the dirt collection groove 411 of the ink stack table 41, the dirt or sewage generated by the ink pad 42 cleaning the print module 13 can be collected in the dirt collection groove 411, so as to prevent the dirt or sewage from splashing in the inkjet printing device 1000. The shape of the ink stack 41 can be a regular shape, such as a square, a circle, etc. Of course, the ink stack 41 can also be an irregular shape, which is not limited in the present application.

[0190] Furthermore, the ink stack module 400 may also include a scraper 43, which is disposed in the dirt collecting tank 411 and arranged side by side with the ink pad 42. It is understandable that the scraper 43 and the ink pad 42 may be arranged side by side along a first direction, so that the print head 100 first contacts the scraper 43 and then contacts the ink pad 42 during the process of moving from the printing station 200 to the ink stack module 400, so that the ink material that has been condensed on the printing module 13 can be better scraped off by the scraper 43, and then the printing module 13 can be kept in a good state for printing after being cleaned by the ink pad 42. Among them, the scraper 43 can be made of materials such as silicone and rubber, so that the scraper 43 can have a certain degree of softness to prevent the scraper 43 from scratching the printing module 13. Of course, the scraper 43 can also be made of other materials. The present application does not limit the shape and material of the scraper 43, and it is sufficient to be able to clean the printing module 13.

[0191] Furthermore, a knife seat 413 is provided in the dirt collecting tank 411, and the scraper 43 is detachably connected to the knife seat 413. The detachable structure of the scraper 43 on the ink stack 41 can facilitate better maintenance or replacement of the scraper 43, avoid damage to the scraper 43 affecting the cleaning effect of the ink stack module 400 on the printing module 13, and further improve the practicality of the inkjet printing device 1000. The scraper 43 can be installed on the knife seat 413 by plugging and unplugging, or the knife seat 413 and the scraper 43 can be fastened and connected by bolts. There are many ways to connect the knife seat 413 and the scraper 43, which is not limited in this application, and can achieve stable connection and convenient disassembly of the scraper 43 and the knife seat 413.

[0192] In addition, the ink stack module 400 further includes a shielding cover 44, which can open or cover the slot of the dirt collecting tank 411. The shielding cover 44 is provided with a first avoidance hole 441, and the ink pad 42 is inserted into the first avoidance hole 441. By providing the shielding cover 44 at the slot of the dirt collecting tank 411, the shielding cover 44 can be used to shield the dirt collecting tank 411, so as to prevent the dirt or sewage in the dirt collecting tank 411 from being exposed and affecting the aesthetics of the inkjet printing device 1000, and at the same time, it is helpful to prevent the inkjet printing device 1000 from shaking during transportation or handling, which may cause the dirt or sewage in the dirt collecting tank 411 to splash out with a certain probability. There may be a certain gap between the outer periphery of the ink pad 42 and the inner wall of the first avoidance hole 441, or a flow groove may be recessed on the inner wall of the first avoidance hole 441 so that the dirt or sewage cleaned by the ink pad 42 can flow stably through the first avoidance hole 441 into the sewage collecting tank 411, thereby reducing the accumulation of dirt or sewage on the shielding cover 44.

[0193] When the ink stack module 400 is provided with a scraper 43, the shielding cover plate 44 may also be provided with a second avoidance hole 443 for the scraper 43 to pass through, so as to ensure that the ink stack module 400 can stably clean the printing module 13. There may be a certain gap between the outer periphery of the scraper 43 and the inner wall of the second avoidance hole 443, or a flow groove may be recessed on the inner wall of the second avoidance hole 443, so that the dirt or sewage cleaned by the ink pad 42 can stably flow into the sewage collection tank 411 through the second avoidance hole 443, thereby reducing the accumulation of dirt or sewage on the shielding cover plate 44.

[0194] See also Fig. 27 and Fig.28 In some embodiments of the present application, the ink stack module 400 further includes a fourth driving mechanism 45, which is in transmission connection with the ink stack platform 41, so that the ink stack platform 41 has a cleaning state close to the printing platform 200, and has an avoidance state away from the printing platform 200. It can be understood that when the print head 100 needs to be cleaned, the fourth driving mechanism 45 can be controlled to drive the ink stack platform 41 to move, so that the ink pad 42 contacts the printing module 13 for cleaning; and when the print head 100 needs to leave the ink stack module 400, the fourth driving mechanism 45 can be controlled to drive the ink stack platform 41 to move, so that the ink stack platform 41 is away from the print head 100 and avoids the movement of the print head 100, which is conducive to better realizing the automatic control of the ink stack module 400. Among them, the fourth driving mechanism 45 can drive the ink stacking platform 41 to move up and down. Of course, the fourth driving mechanism 45 can also be used to drive the ink stacking platform 41 to move horizontally. The present application does not limit the transmission method of the fourth driving mechanism 45, and it is sufficient to realize the movement and switching of the ink stacking platform 41 between the cleaning state and the avoidance state.

[0195] Exemplarily, the fourth driving mechanism 45 may include a fourth support frame 451, a driving motor 453, a screw rod 455, a transmission slider 457 and a transmission connecting rod 459. The screw rod 455 is rotatably connected to the fourth support frame 451. The driving motor 453 is connected to and drives the screw rod 455 to rotate. The transmission slider 457 is sleeved with the screw rod 455 and is arranged in the fourth support frame 451. The transmission connecting rod 459 connects the transmission slider 457 and the ink stacking table 41. By using the driving motor 453 to drive the screw rod 455 to rotate, the transmission slider 457 can be driven by the transmission action of the screw rod 455 to slide on the fourth support frame 451, and then the transmission slider 457 is used to translate and push the transmission connecting rod 459 to drive the ink stacking table 41 to move up and down, thereby ensuring the stable switching of the ink stacking table 41 between the cleaning state and the avoidance state. Further, the fourth support frame 451 has two opposite side plates 4511, at least part of the structure of the ink stack 41 is arranged between the two side plates 4511, the side plate 4511 is provided with a first long hole 4511a extending along the first direction and a second long hole 4511b extending along the third direction, one end of the transmission connecting rod 459 passes through the first long hole 4511a to connect with the transmission slider 457, and the other end of the transmission connection passes through the second long hole 4511b to connect with the ink stack 41. Under the action of the first long hole 4511a and the second long hole 4511b, the movement limit of the transmission connecting rod 459 can be well realized, so that the transmission connecting rod 459 can more stably push the ink stack 41 to move up and down under the translation of the transmission slider 457, and ensure the stable transmission connection of the fourth driving mechanism 45 to the ink stack 41. In addition, the fourth driving mechanism 45 can be provided with at least two transmission connecting rods 459 on the opposite sides of the transmission slider 457, so that the transmission power of the fourth driving mechanism 45 to the ink stacking platform 41 is more uniform and stable, avoiding the deviation of the ink stacking platform 41 during the lifting and lowering process, and further improving the movement stability and reliability of the ink stacking platform 41.

[0196] In some embodiments of the present application, the ink stack module 400 further includes a water inlet pipeline 46 and a sewage discharge pipeline. The water inlet pipeline 46 is connected to the ink pad 42, and the sewage discharge pipeline is connected to the ink stack platform 41 and communicated with the sewage collection tank 411. A pipeline may be provided inside the ink pad 42 so that the ink pad 42 can achieve a certain water spray cleaning function. By connecting the water inlet pipeline 46 to the ink pad 42, a certain amount of clean water or cleaning liquid can be passed into the internal pipeline of the ink pad 42 through the water inlet pipeline 46, and flow out through the water 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 sewage or dirt in the sewage collection tank 411 can be stably discharged through the sewage discharge pipeline to avoid excessive sewage accumulation in the sewage collection tank 411 and overflow, mildew or odor, and further improve the reliability of the ink stack module 400. The other end of the water inlet pipe 46 away from the ink pad 42 can be connected to the water supply equipment outside the inkjet printing device 1000, or, when the ink supply module 300 is provided with a water purification box 317 to store 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. At this time, if the ink supply module 300 is arranged in the housing 700 of the inkjet printing device 1000, a joint connecting the water inlet pipe 46 and the water supply pipe can be provided in the housing 700, so that the water inlet pipe 46 and the water supply pipe are respectively connected to the two ends of the joint, which is convenient for the disassembly, assembly and maintenance of the ink stack module 400 and the ink supply module 300. Of course, the water inlet pipe 46 can also be supplied with water in other ways, which is not limited in this application, and it is sufficient to achieve a stable flow of purified water or cleaning liquid into the water inlet pipe 46. The end of the sewage pipe away from the ink stack 41 can be connected to the waste liquid collection device outside the inkjet printing device 1000, or, when a waste liquid box 500 is provided in the housing 700 of the inkjet printing device 1000, the sewage pipe can be connected to the waste liquid box 500 to ensure the stable discharge of sewage or dirt in the sewage collection tank 411. At this time, a joint structure connecting the sewage pipe and the waste liquid box 500 can be provided in the housing 700 to facilitate the disassembly and maintenance of the ink stack module 400 and the waste liquid box 500. Of course, the sewage pipe can also be discharged in other ways, which is not limited in this application, as long as stable discharge of sewage management can be achieved.

[0197] In addition, when the ink stack module 400 uses the driving mechanism to drive the ink stack platform 41 to move, the support seat of the driving mechanism has a first inner side wall and a second inner side wall connected to each other, the first inner side wall is connected to the first pressing pipe fitting, and the second inner side wall is connected to the second pressing pipe fitting, and the sewage pipeline and the water inlet pipeline 46 are fixed to the first pressing pipe fitting and the second pressing pipe fitting, so that the sewage pipeline and the water inlet pipeline 46 are arranged close to the first inner side wall and the second inner side wall. Under the limiting and fixing action of the first pressing pipe fitting and the second pressing pipe fitting, the sewage pipeline and the water inlet pipeline 46 can be effectively prevented from interfering with the driving components of the driving mechanism in the support seat of the driving mechanism, so as to achieve the avoidance arrangement of the pipelines and ensure the stable operation of the ink stack module 400.
