[0066] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0067] It should be noted that if the embodiments of the present application 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 condition, etc. between components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0068] In addition, if the description of "first", "second" and the like is involved in the embodiments of the present application, the description of "first", "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can be explicitly or implicitly included at least one of the features. In addition, if "and / or" or "and / or" appears throughout the text, it means that the three parallel schemes are included, for example, "A and / or B" includes A scheme, or B scheme, or A and B scheme. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of the ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope required by the present application.

[0069] In the related art, the inkjet printing device can spray ink on the printing material such as paper, film, cloth and the like, so as to accurately form the required image or text on the printing material, and can realize high-definition printing operation, which is 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, and usually needs to be manually cut after printing to achieve the required size, which is relatively 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 printing material after printing, the present application provides an inkjet printing device 1000. It should be noted that the inkjet printing device provided in the present application can be a thermal inkjet printer, a piezoelectric inkjet printer, a white ink ironing printing machine ("Direct to Film", DTF printer), a white ink direct printing machine ("Direct to Garment", DTG printer) and the like, as long as it is used for spraying ink for printing operation. The printing material worked by the inkjet printing device in the present application can be paper, film material, and of course, cloth and the like. The present application does not limit the material and shape of the printing material, and any material that can be printed in the inkjet printing device can be used.

[0071] Please refer to Figures 1 to 5 In an embodiment of the present application, the inkjet printing device 1000 comprises a printing table 200, a print head 100, an ink supply module 300 and a cutter module 15. The print head 100 is movably arranged above the printing table 200 and is used for printing the printing material arranged on the printing table 200. The ink supply module 300 is connected with the print head 100, and is used for supplying ink to the print head 100. The cutter module 15 is movably arranged above the printing table 200, and is used for cutting the printing material on the printing table 200.

[0072] The printing table 200 can form a bearing structure for the whole machine operation process, so that the print head 100 can stably print the printing material carried on the printing table 200, and ensure the stable operation of the inkjet printing device 1000. The printing table 200 can be provided in a regular shape, such as a square body, a circular table, etc., and of course can also be provided in an irregular shape. The specific shape of the printing table 200 is not limited in the present application. The printing table 200 can be used to support the printing material.

[0073] The print head 100 can be integrated with an ink ejection head, a control component, etc., and can realize accurate ejection of the ink supplied by the ink supply module 300 onto the printing material. The principle of the print head 100 for printing operation is the prior art, and therefore the structure of the print head 100 is not limited. The print head 100 can be movably arranged above the printing table 200, which can be driven to move by a track transmission device, or can be driven to move by a mechanical arm or the like. The moving mode of the print head 100 is not limited in the present application, as long as the print head 100 can move on the printing table 200. Further, the print head 100 can perform printing operation according to a certain moving path, so that the print head 100 can better eject ink onto the printing material to form the required image or text.

[0074] The ink supply module 300 can be connected to the print head 100 by a pipeline to transport ink, or can be arranged in the print head 100 to directly transport ink to the printing ejection head in the print head 100. Of course, the ink supply module 300 can also supply ink to the print head 100 in other ways, as long as it can ensure stable transportation of the ink to the print head 100 for inkjet printing. The present application does not limit this.

[0075] By movably arranging the cutter module 15 above the printing table 200, the printing material placed on the printing table 200 can be cut by the cutter module 15, so as to realize the size adjustment of the printing material, which is beneficial to directly cutting the printing material in the printing process, so that the inkjet printing device 1000 can directly output the processed printing material with the required size, and the printing process of the inkjet printing device 1000 is more convenient and reliable. The cutter module 15 can be arranged on the print head 100, and the cutter module 15 is driven to move synchronously by the movement of the print head 100. At this time, the cutter module 15 can be arranged inside the print head 100, or the cutter module 15 can be arranged on the side of the print head 100. Of course, in addition to the synchronous movement of the cutter module 15 driven by the print head 100, the cutter module 15 and the print head 100 can also adopt a connection structure of a sliding rail and a sliding block, so that the cutter module 15 can move relative to the print head 100 to cut the printing material. Alternatively, the cutter module 15 can also be arranged above the printing table 200 in a lifting manner, so that the cutter module 15 can cut the printing material in a lifting and pressing manner. Therefore, there are various installation modes of the cutter module 15 and various cutting modes of the printing material, and the present application does not limit this.

[0076] The technical scheme of the present application can cut the printing material on the printing table 200 by arranging the cutter module 15 above the printing table 200, so that the printing material with the required size can be directly cut by the cutter module 15 after the print head 100 prints the printing material, so as to realize one-time printing on the inkjet printing device 1000, without manually cutting the printing material after printing output, thereby effectively improving the printing convenience and practicality of the inkjet printing device 1000.

[0077] Please refer to Figures 1 to 4 In some embodiments of the present application, the inkjet printing device 1000 further comprises a housing 700, the housing 700 forms a receiving space inside, and the printing table 200, the print head 100 and the cutter module 15 are arranged in the receiving space.

[0078] It can be understood that by arranging 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 beneficial to using the housing 700 to play a certain isolation and protection role, effectively reducing the interference of sundries in the environment on the printing process, and ensuring the stable operation of the printing process. The housing 700 can be arranged in an integral structure, or the housing 700 can be formed by splicing a plurality of housings, and the shape of the housing 700 is not limited in the present application.

[0079] Further, the inkjet printing device 1000 can also set the ink supply module 300 in the accommodation space, so as to realize the more functional integration of the structure design of the inkjet printing device 1000. At this time, the ink supply module 300 can be arranged behind the print head 100, so as to avoid the interference of the ink supply module 300 on the print head 100 in performing the printing operation on the printing table 200, so that the various components of the inkjet printing device 1000 can realize more reasonable layout design in the accommodation space, facilitate the compact design of the inkjet printing device 1000, and further improve the practicability and reliability of the inkjet printing device 1000. For the convenience of understanding and description, the directions indicated by the coordinate system shown in the drawings are taken as the 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. Figure 16 For the convenience of understanding and description, the directions indicated by the coordinate system shown in the drawings are taken as the 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] Please refer to Figure 1 In some embodiments of the present application, the shell 700 is provided with a first opening 71a communicating with the accommodation space, and the first opening 71a is located above the printing table 200. The shell 700 further comprises a first cover plate 71b which can open or cover the first opening 71a.

[0081] In the present application, by arranging the first opening 71a above the printing table 200, the running status of the print head 100, the printing table 200 or other components arranged in the accommodation space can be observed through the first opening 71a, which is beneficial to timely intervene, repair or replace the faulty components, and ensure the stable operation of the inkjet printing device 1000. The first opening 71a can be arranged in a regular shape, such as a rectangle, a circle, etc. Of course, it can also be arranged in an irregular shape, and the shape of the first opening 71a is not limited in the present application.

[0082] 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 arranged, 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 connection modes between the first cover plate 71b and the casing 700, which are not limited in the present application. The first cover plate 71b can be made of a material with certain light transmittance, such as glass, acrylic, etc., which is beneficial to observing the operation status of the components in the accommodation 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 high structural strength, and the material of the first cover plate 71b is not limited in the present application. In addition, the first cover plate 71b can be arranged in a regular shape, such as a square, a circle, etc., and of course, it can also be arranged in an irregular shape, and the shape of the first cover plate 71b is not limited in the present application. The first cover plate 71b can be transparent or translucent to directly observe the printing inside through the first cover plate 71b.

[0083] Further, the casing 700 can be provided with an opening and closing detection device for detecting the opening and closing state of the first cover plate 71b. It can be understood that the opening and closing detection device can have two trigger states. When the first cover plate 71b covers the first opening 71a, one of the trigger states of the opening and closing detection device can be triggered. When the first cover plate 71b opens the first opening 71a, the other trigger state of the opening and closing detection device can be triggered. Then, certain system control can 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 in the accommodation space can be controlled to be in a suspended operation state, facilitating the maintenance and repair of the components. Or, the printing operation can be started only when the opening and closing detection device detects that the first cover plate 71b covers the first opening 71a. Similarly, the opening and closing detection device can also be linked with other control systems, which is not limited in the present application. The structure of the opening and closing detection device has many kinds. For example, a travel switch can be used. When the first cover plate 71b covers the first opening 71a, the trigger part of the travel switch is contacted. When the first cover plate 71b opens the first opening 71a, the trigger part of the travel switch is left. Or, a Hall sensor can be used. At this time, a magnet can be arranged on the first cover plate 71b. When the first cover plate 71b covers the first opening 71a, the magnet is close to the Hall sensor. When the first cover plate 71b opens the first opening 71a, the magnet is away from the Hall sensor. The opening and closing detection device is not limited in the present application.

[0084] Please refer to Figure 2 In some embodiments of the present application, when the ink supply module 300 is arranged in the accommodation space, the casing 700 can be provided with a second opening 72a communicating with the accommodation space. The second opening 72a can correspond to the upper side of the ink supply module 300 or the rear side of the ink supply module 300. The position of the second opening 72a is not limited in the present application. The ink supply module 300 can be exposed through the second opening 72a.

[0085] The second opening 72a can be provided in a regular shape, such as a rectangle, a circle, or the like, or in an irregular shape, and the shape of the second opening 72a is not limited in the present application. Further, the ink supply module 300 can be refilled, maintained, dredged, or the like through the second opening 72a, so as to ensure stable operation of the inkjet printing device 1000. The casing 700 can further include a second cover plate 72b, which can open or cover the second opening 72a. The second cover plate 72b can be connected to the casing 700, such as being slidably connected to the casing 700 to open or cover the second opening 72a, or being rotatably connected to the casing 700 to open or cover the second opening 72a. Alternatively, the second cover plate 72b can be separate from the casing 700, and can be placed on the casing 700 to cover the second opening 72a, or be detached from the casing 700 to open the second opening 72a.

Wherein, the moving path of the print head 100 and the cutter module 15 can have at least partial overlap, for example, the cutter module 15 can be arranged to move synchronously on the print head 100, so that the reflective structure 74 can be arranged at a position where the moving path of the cutter module 15 and the print head 100 overlap; or, the reflective structure 74 can be designed in a larger size, so that the reflective structure 74 can be located on a certain moving path of the print head 100 and a certain moving path of the cutter module 15 at the same time. Of course, the reflective structure 74 can also be designed in other ways, as long as it can be located on the moving path of the print head 100 and the moving path of the cutter module 15, which is not limited in the present application.

[0092] In addition, referring to Figure 16 and Figure 17 When the print head 100 and the cutter module 15 can reciprocate along the first direction, the reflective structure 74 can be arranged with the printing table 200 in the first direction, that is, the reflective structure 74 can be arranged on the left side or the 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 structure 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 accommodation space, as long as they can cooperate with the movement of the print head 100 and the cutter module 15, which is not limited in the present application.

[0103] After the step of printing the printing material is completed, the printing module 13 stops inkjet printing on the printing material, while the cutter assembly 153 is switched to the extended state of extending at least partially out of the second opening 1111b, so that the cutter assembly 153 extending out of the second opening 1111b can cut the printing material that has completed printing.

[0104] Please refer to Figure 10 and Figure 11 In an embodiment of the present application, the first driving mechanism 151 comprises a rotating part 1511, one end of the rotating part 1511 is arranged opposite to the second opening 1111b and connected with the cutter assembly 153, for rotating movement relative to the second opening 1111b, so as to drive the cutter assembly 153 to rotate towards 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 towards or away from the second opening 1111b.

[0112] Of course, the technical solutions of the present application are not limited to this, in some embodiments, the first driving mechanism 151 can include a plurality of driving structures, which can be configured as the rotating part 1511 and the translation part in the foregoing embodiments, so that the cutter assembly 153 can rotate or translate relative to the second opening 1111b in a multi-axis direction under the driving of the first driving mechanism 151, so that the freedom of motion of the cutter assembly 153 can be improved. The specific embodiments can be set according to actual needs, which are not limited here.

[0113] Please refer to Figure 11 In the embodiments of the present application, the cutter assembly 153 includes a frame body 1531 and a cutter 1533, one end of the frame body 1531 is in transmission connection with the first driving mechanism 151; the cutter 1533 is arranged at one end of the frame body 1531 away from the first driving mechanism 151 and is detachably connected with the frame body 1531.

[0114] Among them, the frame body 1531 as a fixed structure for installing the cutter 1533 can be in transmission connection with the first driving mechanism 151, so that the cutter 1533 can be driven to extend or retract relative to the second opening 1111b under the driving of the first driving mechanism 151. Since the cutter 1533 is detachably connected with the frame body 1531, and the cutter assembly 153 is arranged opposite to the second opening 1111b, the user can assemble or disassemble the cutter 1533 to or from the frame body 1531 through the second opening 1111b without disassembling the shell 11, thereby improving the convenience of disassembling the cutter 1533.

[0115] In the embodiments, the frame body 1531 can 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 realize quick positioning of the cutter 1533 and the frame body 1531, and the connection stability between the cutter 1533 and the frame body 1531 can be improved.

It can be understood that when the cutter 1533 cuts the printing material, the material pressing member 1535 can press the printing material from the side of the cutter 1533 through the outer peripheral surface thereof, so as to avoid the printing material from being lifted to affect the cutting effect of the cutter assembly 153 on the printing material. The material pressing member 1535 can be in the form of a wheel body, the central axis direction of which is perpendicular to the cutting surface of the cutter 1533. Of course, the material pressing member 1535 can also be arranged in other shapes, which are not limited herein.

[0118] In the embodiment, the side wall of the frame body 1531 can be provided with a surrounding edge structure 1531b, which is arranged at the end of the material pressing member 1535 away from the second opening 1111b and surrounds the material pressing member 1535.

The frame body 1531 and the material pressing member 1535 can also be positioned and limited by other limiting structures, such as the cooperation of positioning holes and positioning protrusions, which are not limited herein.

[0119] Further, the material pressing member 1535 can be detachably connected with the frame body 1531, so as to facilitate the maintenance or replacement of the material pressing member 1535. Specifically, the material pressing member 1535 can be detachably connected with the frame body 1531 by magnetic attraction cooperation, or can be detachably connected with the frame body 1531 by threaded connection, which are not limited herein.

[0120] In a feasible implementation, the cutter assembly 153 further comprises a fastener, which can be a screw. A screw hole can be formed in the frame body 1531. The fastener can be sequentially threaded through the cutter 1533 and the material pressing member 1535 and be threadedly connected with the frame body 1531, that is, the cutter 1533 and the material pressing member 1535 can be locked on the frame body 1531 by the same fastener. Of course, the cutter 1533 and the material pressing member 1535 can also be respectively fixedly connected with the frame body 1531 by different fasteners. In this way, the cutter 1533 or the material pressing member 1535 can be individually disassembled according to the use requirement.

[0122] In the embodiment, the inkjet printing device can be a white ink ironing printing machine, and the DTF ink used by the white ink ironing printing machine generally comprises four colors of CMYK (Cyan Magenta Yellow blacK) and white. Correspondingly, the printhead 100 comprises two printing modules 13, one of which is a color ink printing module for realizing the color ink printing function corresponding to the four colors of CMYK, and the other is a white ink printing module for realizing the white ink printing function. In use, the printhead 100 can first print a color pattern or text 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, the color of the color pattern or text obtained by printing can be made more vivid by printing white ink on the printing material.

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

[0124] In another embodiment, the two printing modules 13 can also be arranged closely, 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 transmission direction of the printing material, that is, can be arranged in sequence along the second direction. In this way, the printing material can be docked 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. Moreover, after the printing material completes the printing and printing material segmentation steps, it needs to be transferred to an oven or a curing machine for subsequent printing material drying steps, and the inkjet printing device and the oven or the curing machine generally connect in sequence along the transmission direction of the printing material. Therefore, the color ink printing module, the white ink printing module, and the cutter module 15 arranged in sequence along the transmission direction of the printing material also facilitate the transfer of the segmented printing material to the oven or the curing machine.

[0130] In the embodiment of the present application, the printhead 100 further comprises a main board 17, which is arranged in the accommodating cavity and connected to the cavity wall on the side of the accommodating cavity facing the connecting piece 113; the main shell 111 comprises a heat dissipation part 1111c, which is located on the side of the main shell 111 facing the connecting piece 113 and is arranged to avoid the connecting piece 113, and at least part of the main board 17 abuts against the heat dissipation part 1111c to dissipate heat through the heat dissipation part 1111c.

[0131] Further, at least part of the connecting piece 113 is flush with the height of the heat dissipation part 1111c, and on this basis, an avoidance groove can be arranged on the side of the connecting piece 113 facing the main shell 111 corresponding to the region of the heat dissipation part 1111c, and the heat dissipation part 1111c is arranged in the avoidance groove, so that the heat dissipation part 1111c and the connecting piece 113 can be arranged to avoid each other. Of course, the heat dissipation part 1111c and the connecting piece 113 can also be arranged to be staggered in the height direction to avoid each other, which is not limited herein.

[0132] Further, in order to improve the heat dissipation effect, the main shell 111 is further provided with a heat dissipation hole 1111d corresponding to the region of the main board 17, for example, please refer to Figure 5 One or more heat dissipation holes 1111d can be arranged on both sides of the main shell 111 corresponding to the main board 17. The heat dissipation hole 1111d is in communication with the accommodating cavity in the main shell 111 to ventilate and dissipate heat for the components such as the main board 17 in the accommodating cavity.

[0133] Please refer to Figures 5 to 9 In the embodiment of the present application, the shell 11 further comprises a mounting piece 115, one end of the mounting piece 115 is arranged on the side of the main shell 111 away from the connecting piece 113, and the other end extends in the direction away from the main shell 111; the printhead 100 further comprises a camera module 18, which is mounted on the mounting piece 115.

[0134] It can be understood that by arranging the camera module 18 on the printhead 100, the printing path of the printhead 100 can be photographed, whether the printing path of the printhead 100 is a straight line can be detected, and the printing position of the printhead 100 can be further calibrated based on the detection result, thereby facilitating to ensure the printing quality of the printhead 100.

[0135] In an 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 in transmission connection with an external driving device, which can be arranged inside a machine housing of the inkjet printing device, for example, at the rear of the print head 100. The external driving device can drive the print head 100 to move in a direction perpendicular to the arrangement direction of the mounting member 115 and the connecting member 113. In this way, the volume of the print head 100 in the direction perpendicular to the arrangement direction of the mounting member 115 and the connecting member 113 can be reduced, so that the print head 100 can have sufficient space for moving and transferring. Of course, the present application is not limited to this, and in other embodiments, the driving device can be in transmission connection with the main housing 111 or the mounting member 115, and can drive the print head 100 to move in a direction perpendicular to the arrangement direction of the mounting member 115 and the connecting member 113.

[0136] In the embodiment of the present application, the mounting member 115 can be a hollow box structure, and an inner cavity for accommodating the camera module 18 is formed in the mounting member 115. The inner cavity can be in communication with the accommodating cavity of the main housing 111, and a through hole is formed in the outer wall of the mounting member 115 and communicates with the inner cavity, so that the camera module 18 can shoot outward through the through hole. Alternatively, the mounting member 115 can be a plate structure for fixedly connecting the camera module 18, and the camera module 18 can be fixed to the bottom of the plate structure. The mounting member 115 can be arranged separately from the main housing 111, or the mounting member 115 and the main housing 111 can be arranged integrally, so as to improve the stability of the overall structure of the print head 100.

[0137] In the embodiment of the present application, 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 metal material. Compared with this, in the technical scheme of the present application, at least part of the main housing 111 is made of plastic material, which is beneficial to reduce the weight of the housing 11, so as to facilitate the driving of the print head 100 by the external driving device, and to provide more margin for the speed adjustment of the print head 100. In addition, the selection of the plastic material is also beneficial to reduce the preparation cost of the housing 11.

[0138] In the embodiment of the present application, the connecting member 113 is made of 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 weight of the whole print head 100 is mainly supported by the connecting member 113. By setting the material of the connecting member 113 as metal material, the structural strength of the connecting member 113 can be guaranteed, so as to guarantee the structural stability of the inkjet printing device.

[0139] Please refer to Figures 13 to 14In some embodiments, the printing module 13 comprises an inkjet mechanism 131, an ink storage mechanism 133, and a leakage prevention mechanism (not shown). The inkjet mechanism 131 is arranged on the first opening 1111a. The ink storage mechanism 133 is detachably connected to the inkjet mechanism 131 to supply ink to the inkjet mechanism 131. The leakage prevention mechanism is connected between the inkjet mechanism 131 and the ink storage mechanism 133 to prevent ink in the ink storage mechanism 133 from leaking out when the ink storage mechanism 133 is detached from the inkjet mechanism 131. The inkjet mechanism 131 is configured to spray ink.

[0140] In some embodiments, the ink storage mechanism 133 can be a color ink supply mechanism such as a color ink cartridge or a white ink supply mechanism such as a white ink cartridge. The inkjet mechanism 131 can be a nozzle configured to print ink provided by the ink cartridge on a printing material in an inkjet printing manner.

[0141] In some embodiments, the ink storage mechanism 133 and the inkjet mechanism 131 can be connected by plug-in cooperation, which can achieve quick plug-in and plug-out of the ink storage mechanism 133 and the inkjet mechanism 131, and improve the assembly convenience of the printing module 13. Of course, the ink storage mechanism 133 and the inkjet mechanism 131 can also be connected by snap connection, threaded connection, or other detachable connection, which is not limited herein. In addition, the ink storage mechanism 133 can be connected to the ink supply module 300 in a pipeline manner, so that the ink supply module 300 can supply ink to the ink storage mechanism 133, and the ink storage mechanism 133 can spray the ink to the printing material through the inkjet mechanism 131.

[0142] It should be noted that in a printing module 13, the ink storage mechanism 133 can be provided with a plurality of ink storage mechanisms 133 connected side by side on the inkjet mechanism 131. To improve the connection stability between the ink storage mechanism 133 and the inkjet mechanism 131, the inkjet mechanism 131 can be provided with a plurality of positioning grooves 1311, which are shaped like the inkjet mechanism 131. Each positioning groove 1311 is configured to limit the cooperation of an inkjet mechanism 131. Of course, the inkjet mechanism 131 can also limit the ink storage mechanism 133 by other positioning structures, which is not limited herein.

[0143] The ink storage mechanism 133 and the inkjet mechanism 131 are detachably connected, that is, the ink storage mechanism 133 can be separated and removed after being installed on the inkjet mechanism 131, so as to facilitate the maintenance and replacement of the structures of the printing module 13. On this basis, by connecting the leakage prevention mechanism between the inkjet mechanism 131 and the ink storage mechanism 133, when the leakage prevention mechanism is detached from the inkjet mechanism 131, the ink in the ink storage mechanism 133 can be prevented from leaking out and directly entering the accommodating cavity, which can cause pollution to other structures of the print head 100.

[0144] The leakage prevention mechanism can be specifically configured as a leakage prevention valve, which is opened to connect the ink storage mechanism 133 and the ink ejection mechanism 131 when the ink storage mechanism 133 is connected to the ink ejection mechanism 131, and is closed to stop the ink storage mechanism 133 from discharging ink when the ink storage mechanism 133 is disconnected from the ink ejection mechanism 131.

[0145] In a feasible implementation, the inkjet printing device can be a white ink ironing printing machine. Correspondingly, in 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 cartridges corresponding to CMYK four colors, and the other printing module 13 can also be provided with four ink storage mechanisms 133, which are all white ink cartridges. In 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, the color of the color pattern obtained by printing can be made more vivid by printing white ink on the printing material.

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

[0147] Please refer to Figure 6 and Figure 13 In some embodiments, the printing module 13 further includes a conversion board 134, which can be electrically connected to the ink ejection mechanism 131, and the input interface of the conversion board 134 can be connected to the main board 17. The conversion board 134 can be connected to a plurality of ink ejection heads (such as 4 in Figure 13 When the printing module 13 is assembled, only one flat cable is needed to connect the main board 17 and the conversion board 134 together, and multiple flat cables are not needed to connect the main board and the plurality of ink ejection heads, which is more convenient for wiring and simpler for assembly.

[0148] Please refer to Figure 6 and Figure 7 In the embodiments of the present application, the print head 100 further includes an anti-collision mechanism 19 arranged on the housing 11 for preventing the housing 11 from being externally collided. It can be understood that by arranging the anti-collision mechanism 19 on the print head 100 to prevent the housing 11 from being externally collided, the safety of the print head 100 can be improved.

[0149] The anti-collision mechanism 19 can be arranged on the side of the shell 11 to avoid collision between the outer side wall of the print head 100 and the external structure. For example, the print head 100 can move in the first direction, and the anti-collision mechanism 19 can be arranged on the opposite sides of the print head 100 in the first direction, so as to avoid the risk of collision between the shell 11 and the external structure when the print head 100 moves in the first direction. Alternatively, the anti-collision mechanism 19 can also be arranged on the bottom of the shell 11 to avoid collision between the printing surface at the bottom of the print head 100 and the external structure, and thus achieve the effect of preventing hand pinching. Alternatively, the anti-collision mechanism 19 can also be arranged on the side and the 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 achieve the anti-collision function of other positions of the shell 11. The number of the anti-collision mechanism 19 arranged on the shell 11 can be one, two or more. That is, the application does not limit the arrangement position and the number of the anti-collision mechanism 19.

[0150] Further, when the anti-collision mechanism 19 is arranged on the side and the bottom of the shell 11, the anti-collision mechanisms 19 arranged on the side and the bottom of the shell 11 can be integrated and arranged as a whole. In this way, the number of parts on the print head 100 can be reduced, so as to improve the structural integration and assembly efficiency of the print head 100.

[0151] In an embodiment, the anti-collision mechanism 19 can be arranged on the shell 11 of the print head 100 and at least partially protrude from the outer surface of the shell 11. In this way, during the movement of the print head 100, the anti-collision mechanism 19 can detect whether it contacts the external structure by 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 shell 11, it can contact the external structure before the shell 11, so as to brake the shell 11 in time when the anti-collision mechanism 19 is triggered, to avoid collision between the shell 11 and the external structure due to excessive movement.

[0152] Alternatively, in another embodiment, the anti-collision mechanism 19 can also detect the distance between 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 shell 11 can be braked in time when it is detected that the distance between the anti-collision mechanism 19 and the external structure is too close, so as to avoid collision between the shell 11 and the external structure due to excessive movement. The specific arrangement can be set as required and is not limited herein.

[0153] Please refer to Figure 16 and Figure 20In some embodiments of the present application, the inkjet printing device 1000 further comprises a negative pressure module 29, and the printing table 200 is provided with a suction cavity 21, and the surface of the printing table 200 is provided with a vacuum hole 24 communicating with the suction cavity 21, and the negative pressure module 29 is arranged in the suction cavity 21.

[0154] In this embodiment, the suction cavity 21 with a certain space can be formed in the printing table 200, and the negative pressure module 29 can be operated in the suction cavity 21 to form a certain vacuum negative pressure environment in the suction cavity 21, so that the printing material placed on the surface of the printing table 200 can be subjected to the negative pressure action 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 deviating during processing, reducing printing waste, and ensuring the accurate printing effect of the inkjet printing device 1000. The negative pressure module 29 can adopt various types of structures, such as axial flow fans and centrifugal fans, and the type of the negative pressure module 29 is not limited in the present application, which can extract air in the suction cavity 21 to form a certain negative pressure environment. In addition, a single negative pressure module 29 can be arranged in the suction cavity 21, or multiple negative pressure modules 29 can be arranged in the suction cavity 21 to improve the rate of forming a negative pressure environment, and the number of negative pressure modules 29 is not limited in the present application.

[0155] Further, in an embodiment, the suction cavity 21 can be arranged in a flat shape, and the negative pressure module 29 can adopt the structure of a centrifugal fan. It can be understood that the height of the centrifugal fan is small, which can be more conveniently arranged in the flat suction cavity 21, which is beneficial to better reduce the height size of the printing table 200, reduce the occupied space of the bearing assembly in the machine body, and realize better space layout of various components in the inkjet printing device 1000.

[0156] Please refer to Figures 16 to 18 In some embodiments of the present application, the printing table 200 has opposite feeding sides and discharging sides, and the inkjet printing device 1000 further comprises a feeding mechanism 22, which is arranged on the feeding side of the printing table 200 or integrated in the printing table 200.

[0157] In this embodiment, the printing material can be conveyed from the feeding side of the printing table 200 to the surface of the printing table 200 for printing processing, and then output from the discharging side of the printing table 200 after the processing on the printing table 200 is completed. By arranging the feeding mechanism 22 on the feeding side of the printing table 200, the feeding mechanism 22 can be used to drive the printing material, so that the printing material can be stably moved from the feeding side to the discharging side, realizing the continuous and automatic feeding of the inkjet printing device 1000. For the convenience of understanding and description, the feeding mechanism 22 is arranged on the feeding side of the printing table 200. Figure 16The directions indicated by the coordinate system shown in the figure are taken as references, 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 feeding side and the discharging side of the printing table 200 can be opposite sides in the second direction, so that the printing material is moved under the driving action of the feeding mechanism 22, that is, the printing material can be driven to move in the first direction, at this time, the print head 100 can be moved in the second direction, and then the driving efficiency of the feeding mechanism 22 and the moving speed of the print head 100 can be adjusted to realize accurate printing operation of the print head 100.

[0158] In some embodiments, the feeding mechanism 22 can include a support fixedly installed on the feeding side of the printing table 200, a rotating shaft 221 rotatably arranged on the support, and a roller 223 sleeved on the rotating shaft 221, the rotating shaft 221 can be driven to rotate by using a motor or the like driving member, the roller 223 can be brought into contact with the printing material placed on the feeding side of the printing table 200 by driving the roller 223 to rotate by using the rotating shaft 221, and then the printing material can be driven to move in the second direction under the frictional force between the roller 223 and the printing material, so as to realize stable feeding of the inkjet printing device 1000. Of course, the present application is not limited to this, in other embodiments, the feeding mechanism 22 can also be provided in the structure of a conveying belt, and the present application does not limit the structure shape of the feeding mechanism 22, as long as the conveying of the printing material can be realized.

[0159] In addition, please refer to Figure 18 and Figure 19 In some embodiments of the present application, a limiting plate 25 extending in the second direction can be arranged on the surface of the printing table 200, the limiting plate 25 is arranged opposite to the surface of the printing table 200 and forms a conveying groove 251 with the printing table 200, and the edge of the printing material is clamped in the conveying groove 251. It can be understood that the side edge in the first direction can be bent and connected to the surface of the printing table 200, or the limiting plate 25 can be upwardly bent to form the side edge of the printing table 200, so that the limiting plate 25 is integrally formed with the printing table 200, and the shape of the limiting plate 25 is not limited in the present application. The conveying groove 251 is formed on the printing table 200 by using the limiting plate 25, so that the edge of the printing material is clamped in the conveying groove 251 when the printing material is conveyed in the second direction, so that the limiting plate 25 can limit the conveying of the printing material, effectively prevent the printing material from deviating during conveying and affecting the printing effect to a certain extent, and realize accurate printing processing of the inkjet printing device 1000.

[0160] Please refer to Figure 17In some embodiments of the present application, the inkjet printing device 1000 further comprises a material pressing mechanism 23 arranged above the printing table 200 and used to press the printing material on 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 material 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, reduce the defective rate of the processed printing material, and further improve the reliability of the inkjet printing device 1000.

[0162] Please refer to Figure 17 In some embodiments, the material pressing mechanism 23 can include a second driving mechanism 231 and a pressing wheel 233. The second driving mechanism 231 can include a first support frame 2311, a transmission rod 2313, and a handle 2315. The transmission rod 2313 can be a cam rod structure. The handle 2315 is connected to one end of the transmission rod 2313. The pressing wheel 233 is installed on the transmission rod 2313. The handle 2315 on one side of the first support frame 2311 can drive the transmission rod 2313 to rotate. The cam surface on the transmission rod 2313 can drive the pressing wheel 233 to move towards the printing table 200 to press the printing material. A second elastic member such as a spring or a rubber pad can be arranged in the pressing wheel 233. When the second driving mechanism 231 drives the pressing wheel 233 to move downward, the second elastic member in the pressing wheel 233 can be in a certain elastic deformation state. When it is necessary to remove 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. The flat surface on the transmission rod 2313 can contact the pressing wheel 233. At this time, the second elastic member in the pressing wheel 233 is relieved of stress and recovers from elastic deformation. The pressing wheel 233 is reset away from the printing table 200, thereby realizing stable pressing and avoiding of the pressing wheel 233 on the printing material, ensuring stable printing processing and taking and placing of the printing material on the printing table 200, and further improving the practicability and reliability of the inkjet printing device 1000. Of course, the present application is not limited to this. In other embodiments, the material pressing mechanism 23 can also use the structure of a lifting pressing block. The present application does not limit the structure of the material pressing mechanism 23, as long as it can press the printing material on the printing table 200.

[0163] When the inkjet printing device 1000 further comprises a feeding mechanism 22 to convey the printing material, the material pressing mechanism 23 can be at least partially above the feeding mechanism 22. The material pressing mechanism 23 can press the printing material on the feeding mechanism 22, ensuring the contact between the printing material and the feeding mechanism 22, so that the feeding mechanism 22 can more stably convey the printing material to the surface of the printing table 200.

[0164] Please refer to Figure 18 and Figure 19 In some embodiments of the present application, the printing table 200 can be provided with a material detection mechanism 271, which can 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 can be transmitted to the controller of the inkjet printing device 1000, so that the printing head 100 can be started to execute the printing job after it is identified that the printing table 200 is placed with printing material, thereby preventing the printing head 100 from directly spraying ink onto the printing table 200. In addition, the material detection mechanism 271 can also be used to detect whether there is printing material on the printing table 200, and whether the printing material is successfully loaded, so as to realize the fault detection of the inkjet printing device 1000, and further improve the practicability and reliability of the inkjet printing device 1000.

[0165] Further, please refer to Figure 21 and Figure 22 The printing table 200 can be provided with a detection groove 27, and the material detection mechanism 271 is accommodated in the detection groove 27, so that the material detection mechanism 271 can recognize the printing material on the surface of the printing table 200 through the slot of the detection groove 27, which is beneficial 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 more smoothly processed or transmitted on the printing table 200. At this time, the material detection mechanism 271 can include a signal emitting member and a signal receiving member, the signal emitting member can be used to emit detection light such as infrared light, when there is no printing material on the surface of the printing table 200, the detection light emitted by the signal emitting member is not blocked and reflected, so that the signal receiving member cannot receive the detection light emitted by the signal reflecting part, and the signal receiving member can send a printing material not placed signal to the controller at this time; when the printing table 200 is placed with printing material, the slot of the detection groove 27 is covered by the printing material, so that the detection light reflected by the signal reflecting part is blocked and reflected by the printing material, and then the signal receiving member can receive the light emitted by the signal emitting member, so that the signal receiving member sends a printing material placed signal to the controller at this time. Of course, the present application is not limited to this, in other embodiments, the material detection mechanism 271 can also use a photosensitive sensor, a pressure sensitive sensor, etc., and the present application does not limit the type of the material detection mechanism 271, as long as it can realize the detection of whether there is printing material on the printing table 200.

[0166] Please refer to Figure 4 , Figure 16 and Figure 21In some embodiments of the present application, the inkjet printing device 1000 comprises a moving device 600, which is arranged above the printing table 200 or at one side of the printing table 200 and is connected with the printing head 100 to drive the printing head 100 to move on the printing table 200.

[0167] Further, please refer to Figures 21 to 23 In some embodiments, the moving device 600 comprises a second support frame 61 arranged on the base of the casing 700 and a driving mechanism 63 connected with the second support frame 61, and the printing head 100 is connected with the driving mechanism 63 and is movable relative to the second support frame 61, and the driving mechanism 63 drives the printing head 100 to reciprocate along a first direction.

[0168] For the convenience of understanding and description, the directions indicated by the coordinate system shown in Figure 16 , 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 the present embodiment, the second support frame 61 can be formed by processing steel material with certain structural strength, and of course, it can also be formed by processing pipe structure jointing. The structural material and shape of the second support frame 61 can be various, as long as it can play a certain supporting role, which is not limited in the present application. The driving mechanism 63 can be a transmission mode using synchronous belt (i.e. a combination of pulley and belt), and of course, it can also be a transmission mode using chain transmission (i.e. a combination of sprocket and chain), which is not limited in the present application, as long as it can drive the printing head 100. Further, the first direction can be the length direction of the second support frame 61, i.e. the length direction of the machine body. The printing head 100 is driven by the driving mechanism 63 to reciprocate along the first direction on the second support frame 61, which can adjust the position of the printing head 100 according to a certain movement path, so that the printing head 100 can spray ink on the printing material to form the required image or text.

[0169] Further, please refer to Figure 21 The moving device 600 further comprises a support rail 65 arranged on the second support frame 61 and extending along the first direction, which can be arranged side by side with the driving mechanism 63, and a support sliding block 67 movably connected with the support rail 65, and the printing head 100 is connected with the support sliding block 67. The movement of the support sliding block 67 along the first direction on the support rail 65 can play a certain rigid supporting role for the printing head 100, which is beneficial to share part of the acting force of the printing head 100, reduce the bearing requirement of the driving mechanism 63, and better improve the service life of the driving mechanism 63.

[0170] Further, please refer to Figure 21 and Figure 23 The driving mechanism 63 comprises 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 arranged in a transmission manner 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 be an electric motor, and of course other devices for driving the driving wheel 633 to rotate can also be used. The present application does not limit this.

[0175] It can be understood that the ink supply module 300 can be arranged outside the inkjet printing device 1000, and the ink supply module 300 and the printhead 100 can be connected by an ink supply pipeline to supply ink; 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 arranged in the accommodation space of the housing 700, so that the inkjet printing device 1000 can integrate multiple components in the housing 700, facilitating the appearance and compact design of the inkjet printing device 1000. Of course, the arrangement of the ink supply module 300 is not limited in the present application, as long as the stable arrangement of the ink supply module 300 and the supply of ink from the ink supply module 300 to the printhead 100 can be realized.

[0176] For example, please refer to Figure 15 In some embodiments, when the ink supply module 300 is arranged in the housing 700, the housing 700 can be provided with a third support frame 76 behind the printhead 100, so that the ink cartridges 31 of the ink supply module 300 can be stably arranged and installed on the third support frame 76. Further, the ink cartridges 31 and the printhead 100 can be stably connected and supplied with ink by stably routing the ink supply pipeline 33 in the housing 700. The filter 331 and the pump 333 can be connected in sequence on the ink supply pipeline 33, and the pump 333 can generate a suction force on the ink supply pipeline 33, so that the ink can flow through the filter 331 and the pump 333 and then flow into the printing module 13 of the printhead 100, which is beneficial to reduce the impurities in the ink and prevent the printing module 13 from being blocked, and ensure the stable jet printing of the printing module 13. The filter 331 and the pump 333 can be installed in the housing 700, and the ink cartridges 31, the filter 331, the pump 333 and the printing module 13 can be connected in sequence by a plurality of pipe segments, so as to realize a more compact structure layout of the inkjet printing device 1000.

[0177] Further, referring to Figure 26 , the ink cartridge 31 can be provided with an ink detection device 311, which can be used to detect the amount of ink in the ink cartridge 31. For example, the ink detection device 311 can include a first detection float 3111 provided in the ink cartridge 31 and a first detection signaler 3113 provided outside the ink cartridge 31. The first detection float 3111 can move up and down with the liquid level in the ink cartridge 31, and when the first detection float 3111 moves to a certain height, it can trigger the first detection signaler 3113, so that the first detection signaler 3113 sends a lack of ink or ink full signal to the controller of the inkjet printing device 1000, reminding the user to add ink to the ink cartridge 31 or stop adding ink. The first detection signaler 3113 can be a Hall sensor, and the first detection float 3111 can be provided with a magnet or other trigger structure 47, so that when the first detection float 3111 rises to a position opposite the first detection signaler 3113, the first detection signaler 3113 can be triggered. Of course, the ink detection device 311 can also use a pressure-sensitive sensor or other detection device, which is not limited in the present application.

[0178] In addition, the ink cartridge 31 can also be provided with a guide structure 319 to guide the vertical up-and-down movement of the first detection float 3111, so that the first detection float 3111 can be vertically up-and-down moved along the third direction, avoiding the first detection float 3111 from leaving the detection range of the first detection signaler 3113.

[0179] Referring to Figure 25 , in some embodiments, the ink cartridge 31 can include a first ink cartridge 313 and a second ink cartridge 315, and the first ink cartridge 313 can be provided with a stirring mechanism 35.

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 ink. Of course, the present application is not limited to this, and in other embodiments, the first ink cartridge 313 and the second ink cartridge 315 can also be used to store other different types of ink to ensure the printing function of the inkjet printing device 1000. When the first ink cartridge 313 is loaded with white ink or other ink that is prone to condensation, the stirring mechanism 35 can be used to stir the ink in the first ink cartridge 313, which can effectively prevent the ink in the first ink cartridge 313 from condensing and ensure the fluidity of the ink in the first ink cartridge 313.

[0180] Further, referring to Figure 25In some embodiments, the stirring mechanism 35 comprises stirring blades 351 rotatably arranged in the first ink cartridge 313 and a stirring motor 353 arranged on the outer wall of the first ink cartridge 313, and the rotating shaft 221 of the stirring motor 353 is connected to the stirring blades 351 through the wall of the first ink cartridge 313.

The ink supply pipeline 33 can move more stably with the print head 100 by using the drag chain structure 77, the drag force of the ink supply pipeline 33 is reduced, and the leakage between the ink supply module 300 and the print module 13 is better avoided.

[0184] Referring to Figure 4 , Figure 16 and Figure 27 , in some embodiments of the present application, the inkjet printing device 1000 further comprises an ink stack module 400 for cleaning and / or moisturizing the print module 13 of the print head 100.

[0185] In the embodiment, the ink stack module 400 can be used to clean and / or moisturize the printing module 13, which is conducive to avoiding the condensation of ink at the nozzle of the printing module 13, preventing the nozzle from being blocked, and ensuring the stable operation of the print head 100. The cleaning method of the ink stack module 400 for the printing module 13 can be various, for example, the condensed ink on the printing module 13 can be removed by scraping, or the printing module 13 can be cleaned by using a cleaning agent. Of course, the cleaning method of the ink stack module 400 can also be a combination of multiple cleaning methods, such as the method of scraping first and then cleaning, and the like. The cleaning method of the ink stack module 400 is not limited in the present application, as long as the ink stack module 400 can clean the printing module 13.

[0186] The ink stack module 400 can be arranged 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 the more compact structure design of the inkjet printing device 1000.

[0187] Further, please refer to Figure 27 and Figure 28 The ink stack module 400 can have a cleaning surface, and the ink stack module 400 includes a trigger structure 47 arranged on the cleaning surface, and the trigger structure 47 is used to detect and position the print head 100.

[0188] For example, the trigger structure 47 can be a protruding structure arranged on the cleaning surface. By arranging a groove at a corresponding position of the printing module 13, the print head 100 can be correspondingly positioned above the ink stack module 400, and when the cleaning structure of the ink stack module 400 corresponds to the printing module 13, the protruding structure is just inserted into the groove. At this time, the protruding structure or the groove can be provided with a corresponding trigger sensor, so that the controller of the inkjet printing device 1000 can know that the print head 100 is arranged on the ink stack module 400. At this time, the ink stack module 400 can be started to clean the printing module 13 stably, and the accurate positioning of the print head 100 and the ink stack module 400 is realized. When the trigger structure 47 is not triggered, a stop signal can be sent to the ink stack module 400 to avoid the ink stack module 400 from idling or leaking due to the deviation of the print head 100 from the ink stack module 400, and to ensure the 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 sensor, a distance sensor, and the like. The type of the trigger structure 47 is not limited in the present application, as long as the print head 100 and the ink stack module 400 can be correspondingly detected.

[0189] Please refer to Figure 27 and Figure 28In some embodiments, the ink stack module 400 can include an ink stack table 41 and an ink pad 42, the top surface of the ink stack table 41 is provided with a sump 411, and the ink pad 42 is arranged in the sump 411. 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 certain condensation ink absorption function, or a cleaning pad with certain condensation ink wiping function, etc. The type of ink pad 42 is not limited in the present application, as long as it can realize the cleaning function of the print module 13. By arranging the ink pad 42 in the sump 411 of the ink stack table 41, the dirt or sewage generated by the cleaning of the print module 13 by the ink pad 42 can be collected in the sump 411, preventing the dirt or sewage from splashing in the inkjet printing device 1000. The shape of the ink stack table 41 can be a regular shape, such as a square or a circle. Of course, the ink stack table 41 can also be arranged in an irregular shape, which is not limited in the present application.

[0190] Further, the ink stack module 400 can also include a scraper 43 arranged in the sump 411 and arranged side by side with the ink pad 42. It can be understood that the scraper 43 and the ink pad 42 can be arranged side by side in the first direction, so that the print head 100 can first contact the scraper 43 and then contact the ink pad 42 during the movement of the print head 100 from the printing table 200 to the ink stack module 400. The scraper 43 can better scrape off the ink that has been condensed on the print module 13 under the action of the scraper 43, and the print module 13 can be kept in a good state for printing work after being cleaned by the ink pad 42. The scraper 43 can be made of silicone, rubber or other materials, so that the scraper 43 can have a certain softness to prevent the scraper 43 from scratching the print module 13. Of course, the scraper 43 can also be made of other materials, and the shape and material of the scraper 43 are not limited in the present application, as long as it can realize the cleaning of the print module 13.

[0191] Further, the sump 411 is provided with a tool holder 413, and the scraper 43 is detachably connected to the tool holder 413.

The scraper 43 can be installed on the tool holder 413 by clamping and plugging, or the tool holder 413 and the scraper 43 can be connected by bolts. There are many connection methods of the tool holder 413 and the scraper 43, which are not limited in the present application, as long as the stable connection and convenient disassembly of the scraper 43 and the tool holder 413 can be realized.

By arranging the shielding cover plate 44 at the slot of the dirt collecting tank 411, the dirt collecting tank 411 can be shielded by the shielding cover plate 44, so as to avoid that the dirt or sewage in the dirt collecting tank 411 is exposed to affect the appearance of the inkjet printing device 1000, and meanwhile, it is beneficial to avoid that the inkjet printing device 1000 shakes during transportation or carrying and has a certain probability to cause the dirt or sewage in the dirt collecting tank 411 to splash out. The outer periphery of the ink pad 42 and the inner wall of the hole of the first avoiding hole 441 can have a certain gap, or the inner wall of the hole of the first avoiding hole 441 can be concave to form a flow groove, so that the dirt or sewage cleaned by the ink pad 42 can stably flow into the dirt collecting tank 411 through the first avoiding hole 441, and the accumulation of dirt or sewage on the shielding cover plate 44 is reduced.

[0193] When the ink stack module 400 is provided with the scraper 43, the shielding cover plate 44 can further be provided with a second avoiding 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. The outer periphery of the scraper 43 and the inner wall of the hole of the second avoiding hole 443 can have a certain gap, or the inner wall of the hole of the second avoiding hole 443 can be concave to form a flow groove, so that the dirt or sewage cleaned by the ink pad 42 can stably flow into the dirt collecting tank 411 through the second avoiding hole 443, and the accumulation of dirt or sewage on the shielding cover plate 44 is reduced.

[0194] Please refer to Figure 27 and Figure 28 In some embodiments of the present application, the ink stack module 400 further comprises a fourth driving mechanism 45, which is in transmission connection with the ink stack table 41, so that the ink stack table 41 has a cleaning state close to the printing table 200 and an avoiding state away from the printing table 200. It can be understood that when the printing head 100 needs to be cleaned, the fourth driving mechanism 45 can be controlled to drive the ink stack table 41 to move, so that the ink pad 42 contacts the printing module 13 for cleaning; and when the printing head 100 needs to be away from the ink stack module 400, the fourth driving mechanism 45 can be controlled to drive the ink stack table 41 to move, so that the ink stack table 41 is away from the printing head 100 to avoid the movement of the printing head 100, which is beneficial to better realize the automatic control of the ink stack module 400. The fourth driving mechanism 45 can drive the ink stack table 41 to move up and down, of course, the fourth driving mechanism 45 can also drive the ink stack table 41 to move horizontally, and the transmission mode of the fourth driving mechanism 45 is not limited in the present application, as long as the fourth driving mechanism 45 can realize the movement switching of the ink stack table 41 between the cleaning state and the avoiding state.

[0195] Exemplarily, the fourth driving mechanism 45 can include a fourth support frame 451, a driving motor 453, a screw rod 455, a transmission sliding block 457 and a transmission connecting rod 459.

By driving the screw rod 455 to rotate by the driving motor 453, the transmission sliding block 457 can be driven by the transmission of the screw rod 455 to slide on the fourth support frame 451, and then the transmission sliding block 457 is used to push the transmission connecting rod 459 to drive the ink stack table 41 to move up and down, thereby ensuring the stable switching of the ink stack table 41 between the cleaning state and the avoiding state. Further, the fourth support frame 451 has two opposite side plates 4511, at least part of the structure of the ink stack table 41 is arranged between the two side plates 4511, the side plates 4511 are 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 the transmission sliding block 457, and the other end of the transmission connecting rod 459 passes through the second long hole 4511b to connect the ink stack table 41. Under the action of the first long hole 4511a and the second long hole 4511b, the movement of the transmission connecting rod 459 can be well limited, so that the transmission connecting rod 459 can more stably push the ink stack table 41 to move up and down under the translation of the transmission sliding block 457, thereby ensuring the stable transmission connection of the fourth driving mechanism 45 to the ink stack table 41. In addition, the fourth driving mechanism 45 can be provided with at least two transmission connecting rods 459 on opposite sides of the transmission sliding block 457, so that the transmission power of the fourth driving mechanism 45 to the ink stack table 41 is more uniform and stable, avoiding the deviation of the ink stack table 41 during the lifting process, and further improving the movement stability and reliability of the ink stack table 41.

[0196] In some embodiments of the present application, the ink stack module 400 further comprises a water inlet pipeline 46 connected to the ink pad 42 and a sewage discharge pipeline connected to the ink stack table 41 and communicating with the sewage collection tank 411.
