[0066] In the related art, the inkjet printing device can print patterns on the printing material through the print head, so that the part of the printing material can be laid on the fabric, and the pattern is transferred to the surface of the fabric by using the heat transfer process. However, the print head in the current inkjet printing device usually only has the inkjet printing function, and cannot automatically cut the printing material according to the size of the printing pattern. After completing the pattern printing on the printing material, the printing material needs to be transferred to the outside of the inkjet printing device for cutting processing, which is inconvenient to use.

[0067] Therefore, based on the above consideration, the present application provides a print head 100. The print head 100 comprises a shell 10, a print module 20 and a cutter module 30. The print module 20 and the cutter module 30 are integrated in the shell 10, so that the print head 100 has the functions of pattern printing and printing material cutting, which is beneficial to improve the practicability of the print head 100.

[0068] Next, the structure of the print head 100 proposed in the present application is explained and described in the embodiments of the present application.

[0069] The shell 10 can be a box structure with an internal cavity, and is used for forming a containing cavity for placing the printing module 20, so as to isolate and protect the functional module placed in the shell 10, and improve the protection performance of the print head 100. The printing module 20 can be placed in the containing cavity of the shell 10, or a part of the printing module 20 can be placed in the containing cavity and the other part of the printing module 20 can be placed outside the containing cavity, which is not limited herein. In some embodiments, the shell 10 can be a cuboid, a square or other shapes.

[0070] Further, one of the outer walls of the shell 10 is used for forming a working surface 1111. A first opening 1111a is formed on the working surface 1111, so that the printing module 20 in the containing cavity can work outwardly to print a preset pattern on the printing material.

[0071] In an embodiment of the present application, the cutter module 30 can be arranged outside the shell 10. For example, the cutter module 30 can be mounted on the outer wall of the shell 10, and at least a part of the cutter module 30 can protrude from the working surface 1111. Alternatively, a groove can be formed on the working surface of the shell, and the cutter module 30 can be arranged in the groove, and at least a part of the cutter module 30 can protrude from the groove to protrude from the working surface 1111.

The fastener 325 can be threadedly connected to the frame 321 by sequentially penetrating the cutter 322 and the pressure piece 323, so that the cutter 322 and the pressure piece 323 can be locked to the frame 321 by the same fastener 325. Of course, the cutter 322 and the pressure piece 323 can also be fixedly connected to the frame 321 by different fasteners 325 respectively. In this way, the cutter 322 or the pressure piece 323 can be disassembled individually according to the use requirement.

[0101] Of course, in some embodiments, the pressure piece 323 can also be arranged independently of the frame 321 of the cutter assembly 32 and the cutter 32. Correspondingly, the cutter module 30 can be provided with two driving mechanisms 31 for driving the cutter 322 and the pressure piece 323 to move, which is not limited herein.

[0102] Please refer to Figure 6 and Figure 7 In one embodiment of the utility model, the cutter module 30 further comprises a cutter housing 33, and the cutter housing 33 is formed with a mounting cavity. An avoiding opening 3311 is formed in the outer wall of the cutter housing 33 and is communicated with the mounting cavity. The avoiding opening 3311 and the second through opening 1111b are arranged oppositely and are exposed through the second through opening 1111b. The driving mechanism 31 and the cutter assembly 32 are arranged in the mounting cavity, and when the cutter assembly 32 is in the working state, the cutter assembly 32 at least partially extends out of the second through opening 1111b through the avoiding opening 3311.

[0103] It can be understood that by arranging the cutter housing 33, the driving mechanism 31, the cutter assembly 32 and other functional components of the cutter module 30 can be arranged in the mounting cavity formed in the cutter housing 33, so as to realize the modularization arrangement and improve the assembly convenience of the cutter module 30.

[0104] The cutter housing 33 can be a box structure with an internal cavity. The cutter housing 33 can also play a role in isolating and protecting the driving mechanism 31, the cutter assembly 32 and other functional components arranged in the mounting cavity. In some embodiments, the cutter housing 33 can be a cuboid, a square or other shapes.

[0105] Please refer to Figure 6 and Figure 7In an embodiment of the utility model, the cutter shell 324 includes main body part 33a and clamping part 33b connected in sequence, main body part 33a is arranged in the accommodating cavity, and is arranged opposite to the second pass opening 1111b;One end of clamping part 33b is connected to main body part 33a, and the other end extends towards the second pass opening 1111b, clamping part 33b is at least partially clamped with the second pass opening 1111b to be exposed through the second pass opening 1111b, and the side of clamping part 33b exposed to the second pass opening is provided with a clearance 3311.

[0106] In this way, at least part of the cutter shell 33 can be clamped and matched with the second pass opening 1111b on the casing 10, thereby facilitating the quick positioning of the cutter module 30 and the casing 10, and the assembly stability of the cutter module 30 can be improved.

[0107] Specifically, referring to Figure 8 In an embodiment of the utility model, the cutter shell 33 is composed of a rear shell 331 and a front cover 332, wherein the rear shell 331 forms a mounting space with a side opening, and the front cover 332 is hingedly arranged at the opening of the rear shell 331 to form a mounting cavity with the rear shell 331. The rear shell 331 and the front cover 332 can be detachably connected. Moreover, the bottom end of the rear shell 331 is arranged opposite to the second pass opening 1111b, and the end face of the bottom end is provided with a clearance 3311 communicating with the mounting cavity. At least part of the cutter assembly 32 can extend out of the second pass opening 1111b from the mounting cavity through the clearance 3311 to realize the function of cutting the printing material.

[0108] Referring to Figures 1 to 5 In an embodiment of the utility model, two first pass openings 1111a are arranged on the working surface 1111 at intervals, the printing module 20 is provided with two, each printing module 20 is arranged corresponding to a first pass opening 1111a, and the cutter module 30 is arranged between the two printing modules 20, or the cutter module 30 is arranged on the side of one printing module 20 away from the other printing module 20.

[0109] In this embodiment, the inkjet printing device can be a white ink ironing printing machine, which usually adopts DTF ink composed of CMYK four colors and white. Correspondingly, the print head 100 is provided with two printing modules 20, one of which is a color ink printing module for realizing the color ink printing function corresponding to CMYK four colors, and the other is a white ink printing module for realizing the white ink printing function. During use, the print head 100 can first print a color pattern on the printing material through one of the printing modules 20, and then print a layer of white ink on the color pattern through the other printing module 20. In this way, the color of the color pattern obtained by printing white ink on the printing material can be more vivid.

[0110] Optionally, in an embodiment, the two printing modules 20 are arranged at intervals, and the cutter module 30 can be arranged at a position between the two printing modules 20. In use, after the color ink printing module and the white ink printing module complete the pattern printing in sequence, the cutter module 30 can be switched from the retracted state to the extended state, and moved to a specific position relative to the printing material, so as to cut the printing material.

[0111] In another embodiment, the two printing modules 20 can also be arranged closely, and the cutter module 30 can be arranged on a side of each cutter module 30 away from another cutter module 30. For example, the color ink printing module, the white ink printing module, and the cutter module 30 are arranged in sequence along the transmission direction of the printing material. In this way, the printing material can be docked with the color ink printing module, the white ink printing module, and the cutter module 30 in sequence during the transmission process, so as to complete the color ink printing, the white ink printing, and the printing material segmentation in sequence. Moreover, after the printing material completes the pattern printing and the printing material segmentation, it still needs to be transferred to the baking machine or the curing machine for the subsequent printing material drying step. Since the inkjet printing device and the baking machine or the curing machine generally connect in sequence along the transmission direction of the printing material, the color ink printing module, the white ink printing module, and the cutter module 30 arranged in sequence along the transmission direction of the printing material also facilitate the transfer of the segmented printing material to the baking machine or the curing machine.

[0112] Please refer to Figures 1 to 5 In the embodiment of the utility model, the shell 10 includes a main shell 11 and a connecting piece 12, the main shell 11 is internally provided with a containing cavity, and one end of the main shell 11 is formed with a working surface 1111; one end of the connecting piece 12 is arranged on the outer side wall of the main shell 11, and the other end extends in a direction away from the main shell 11 and is used for externally connecting a driving device to drive the printhead 100 to move under the driving of the driving device.

[0113] In the embodiment, the main shell 11 can be arranged in an integrated structure and formed by integral injection molding or integral die casting; alternatively, the main shell 11 can also be split into a plurality of shell components and assembled by the plurality of shell components.

[0114] Please refer to Figure 5In an embodiment, the main housing 11 comprises a bottom shell 111 and a cover 112.

The bottom shell 111 can be cuboid, square or other shapes. The cover 112 is arranged above the bottom shell 111 and covers the opening at the top of the bottom shell 111. The cover 112 and the bottom shell 111 form a cavity. The cover 112 can protect the functional modules arranged in the cavity.

[0115] The connecting member 12 is in the form of a plate and is connected to the outer side wall of the main housing 11. The connecting member 12 can be fixedly connected to the outer side wall of the bottom shell 111 or the outer side wall of the cover 112. The other end of the connecting member 12 extends towards the side of the main housing 11. The driving device is connected to the connecting member 12. The driving device drives the connecting member 12 to move the printing head 100 relative to the printing material, so that the printing head 100 can process different positions of the printing material. The connecting member 12 has a bearing surface 121 formed at the top thereof. The connecting member 12 can be connected to the driving device and support the components of the printing head 100.

[0116] Please refer to Figure 2 and Figure 3 In the embodiment, the printing head 100 further comprises a main board 40. The main board 40 is arranged in the cavity and connected to the side wall of the cavity facing the connecting member 12. The main housing 11 comprises a heat dissipation portion 1112. The heat dissipation portion 1112 is arranged on the side of the main housing 11 facing the connecting member 12 and avoids the connecting member 12. At least part of the main board 40 is in abutment with the heat dissipation portion 1112, so that the main board 40 can dissipate heat through the heat dissipation portion 1112.

[0117] The main housing 11 can be connected with a heat dissipation member on the outer side wall thereof to form the heat dissipation portion 1112. The heat dissipation member can be but not limited to a heat dissipation fin. The main housing 11 can be provided with a plurality of protruding structures arranged in an array on the side thereof away from the main board 40. The main housing 11 can form heat dissipation fins through its own structure to form the heat dissipation portion 1112.

[0118] Further, at least part of the connecting piece 12 is flush with the heat dissipation part 1112, on the basis of which, an avoiding groove can be arranged on the side of the connecting piece 12 corresponding to the area of the heat dissipation part 1112, and the heat dissipation part 1112 is arranged in the avoiding groove, so that the heat dissipation part 1112 and the connecting piece 12 are arranged to avoid each other. Of course, the heat dissipation part 1112 and the connecting piece 12 can also be arranged to be staggered in the height direction to achieve mutual avoidance, which is not limited herein.

[0119] Further, in order to improve the heat dissipation effect, the main shell 11 is further provided with a heat dissipation hole 1113 corresponding to the main board 40, for example, please refer to Figure 1 One or more heat dissipation holes 1113 can be arranged on both sides of the main shell 11 corresponding to the main board 40. The heat dissipation hole 1113 is in communication with the accommodating cavity in the main shell 11, so as to ventilate and dissipate heat for the components such as the main board 40 in the accommodating cavity.

[0120] Please refer to Figures 1 to 5 In the embodiment of the utility model, the shell 10 further includes a mounting piece 13, one end of the mounting piece 13 is arranged on the side of the main shell 11 away from the connecting piece 12, and the other end extends in the direction away from the main shell 11; the print head 100 further includes a camera module 50, and the camera module 50 is mounted on the mounting piece 13.

[0121] It can be understood that by arranging the camera module 50 on the print head 100, the printing path of the print head 100 can be photographed, whether the printing path of the print head 100 is a straight line can be detected, and the printing position of the print head 100 can be further calibrated based on the detection result, thereby being beneficial to guarantee the printing quality of the print head 100.

[0122] In an embodiment of the present application, the mounting piece 13 and the connecting piece 12 are arranged on opposite sides of the main shell 11, the connecting piece 12 is in transmission connection with an external driving device, and the external driving device can drive the print head 100 to move in the direction perpendicular to the arrangement direction of the mounting piece 13 and the connecting piece 12. This kind of arrangement mode can reduce the volume of the print head 100 in the direction perpendicular to the arrangement direction of the mounting piece 13 and the connecting piece 12, so that the print head 100 can have sufficient space for moving and loading.

[0123] The mounting piece 13 can be a box structure with an inner cavity for accommodating the camera module 50, and the inner cavity can be in communication with the accommodating cavity of the main shell 11. The outer wall of the mounting piece 13 is provided with a through hole in communication with the inner cavity, so that the camera module 50 can be outwardly photographed through the through hole. Alternatively, the mounting piece 13 can be a plate structure for fixedly connecting the camera module 50, and the camera module 50 can be fixed to the bottom of the plate structure. The mounting piece 13 can be separately arranged from the main shell 11, and the material of the mounting piece 13 can be the same as or different from the main shell 11. For example, the mounting piece 13 can be made of sheet metal to ensure the structural strength, or the mounting piece 13 can be made of plastic to reduce the manufacturing cost of the casing 10 and facilitate the weight reduction of the casing 10. By arranging the mounting piece 13 separately from the main shell 11, the mounting piece 13 can be separately processed when the structure of the mounting piece 13 is complex, thereby reducing the production difficulty of the casing 10. Alternatively, the mounting piece 13 can be integrally arranged with the main shell 11, thereby improving the stability of the overall structure of the print head 100.

[0124] In the embodiment of the present application, at least part of the main shell 11 is made of plastic material. It should be noted that in the related art, the material of the casing 10 of the print head 100 is usually sheet metal. Compared with this, the technical scheme of the present application is that at least part of the main shell 11 is made of plastic material, which is beneficial to reduce the weight of the casing 10, 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. Moreover, the selection of plastic material is also beneficial to reduce the manufacturing cost of the casing 10.

[0125] In the embodiment of the present application, the connecting piece 12 is made of sheet metal. In the inkjet printing device, the print head 100 is connected to the external driving device through the connecting piece 12 of the casing 10, so that the weight of the print head 100 is mainly supported by the connecting piece 12. By setting the material of the connecting piece 12 as sheet metal, the structural strength of the connecting piece 12 can be ensured, thereby ensuring the structural stability of the inkjet printing device.

[0126] Please refer to Figures 10 to 11 In the embodiment of the present application, the printing module 20 comprises an inkjet mechanism 21, an ink supply mechanism 22 and a leakage prevention mechanism. The inkjet mechanism 21 is arranged on the first opening 1111a. The ink supply mechanism 22 is detachably connected with the inkjet mechanism 21 to supply ink to the inkjet mechanism 21. The leakage prevention mechanism is connected between the inkjet mechanism 21 and the ink supply mechanism 22 to prevent the ink in the ink supply mechanism 22 from leaking out when the ink supply mechanism 22 is separated from the inkjet mechanism 21.

[0127] The ink supply mechanism 22 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 ink ejection mechanism 21 can be configured as a printhead for printing ink provided by the ink cartridge on a printing material in a manner of inkjet printing.

[0128] In an embodiment of the present application, the ink supply mechanism 22 and the ink ejection mechanism 21 can be connected through plug-in cooperation, so that the ink supply mechanism 22 and the ink ejection mechanism 21 can be quickly plugged and unplugged, improving the assembly convenience of the printing module 20. Of course, the ink supply mechanism 22 and the ink ejection mechanism 21 can also be detachably connected through snap connection, threaded connection, or other manners, which are not limited herein.

[0129] It should be noted that in a printing module 20, the ink supply mechanism 22 can be provided with multiple ink supply mechanisms 22 connected side by side on the ink ejection mechanism 21. To improve the connection stability between the ink supply mechanism and the ink ejection mechanism 21, the ink ejection mechanism 21 can be provided with multiple positioning grooves 211, which are shaped in imitation of the ink ejection mechanism 21, and each positioning groove 211 is used for limiting cooperation with an ink ejection mechanism 21. Of course, the ink ejection mechanism 21 can also limit the ink supply mechanism 22 through other positioning structures, which are not limited herein. The number of printheads in the ink ejection mechanism 21 can be consistent with the ink supply mechanism 22.

[0130] The ink supply mechanism and the ink ejection mechanism 21 are detachably connected, that is, the ink supply mechanism can be separated and removed after being installed on the ink ejection mechanism 21, so as to facilitate the maintenance and replacement of the structures of the printing module 20. On this basis, by connecting the leakage prevention mechanism between the ink ejection mechanism 21 and the ink supply mechanism 22, it can be avoided that when the leakage prevention mechanism is detached from the ink ejection mechanism 21, the ink in the ink supply mechanism 22 leaks outwardly and directly enters the accommodation cavity, causing pollution to other structures of the printhead 100.

[0131] The leakage prevention mechanism can be specifically configured as a leakage prevention valve, which is opened when the ink supply mechanism is connected with the ink ejection mechanism 21 to make the ink path of the ink supply mechanism 22 and the ink ejection mechanism 21 communicate, and is closed when the ink supply mechanism is disconnected from the ink ejection mechanism 21 to stop the ink supply mechanism 22 from discharging ink outwardly.

[0132] In a feasible implementation, the inkjet printing device can be a white ink ironing printer. Correspondingly, among the two printing modules 20 of the print head 100, one printing module 20 is provided with four ink supply mechanisms 22, which are specifically configured as four color ink cartridges corresponding to CMYK four colors; the other printing module 20 can also be provided with four ink supply mechanisms 22, and the four ink supply mechanisms 22 are all white ink cartridges. In use, the print head 100 can first print a color pattern on the printing material through one printing module 20, and then print a layer of white ink on the color pattern through the other printing module 20. 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.

[0133] Further, in some embodiments, when the four ink supply mechanisms 22 in the printing module 20 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 inkjet mechanism 21, which is conducive to improving the structural integration and disassembly convenience of the printing module 20.

[0134] Please refer to Figure 2 and Figure 10 In some embodiments, the printing module 20 further includes a conversion board 23, which can be electrically connected with the inkjet mechanism 21, and the input interface of the conversion board 23 can be electrically connected with the main board 40. The conversion board 23 can be connected with multiple inkjet heads in the inkjet mechanism 21, so that when the printing module 20 is assembled, only one wire needs to be connected between the main board 40 and the conversion board 23, and multiple wires are not needed to connect the main board and multiple inkjet heads, which is more convenient for wiring and simpler for assembly.

[0135] Please refer to Figure 1 and Figure 2 In the embodiments of the present application, the print head 100 further includes an anti-collision mechanism 60, which is arranged on the casing 10 and is used to prevent the casing 10 from being externally collided. It can be understood that by arranging the anti-collision mechanism 60 on the print head 100 to prevent the casing 10 from being externally collided, the safety of the print head 100 can be improved.

[0136] The anti-collision mechanism 60 can be arranged on the side of the casing 10 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 60 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 casing 10 and the external structure when the print head 100 moves in the first direction. Alternatively, the anti-collision mechanism 60 can also be arranged on the bottom of the casing 10 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 60 can also be arranged on the side and bottom of the casing 10 to improve the comprehensiveness of the protection of the print head 100. Of course, the anti-collision mechanism 60 can also be used to achieve the anti-collision function of other positions of the casing 10. The number of anti-collision mechanisms 60 arranged on the casing 10 can be one, two or more. That is, the application does not limit the arrangement position and number of the anti-collision mechanism 60.

[0137] Further, when the anti-collision mechanism 60 is arranged on the side and bottom of the casing 10, the anti-collision mechanisms 60 arranged on the side and bottom of the casing 10 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.

[0138] In an embodiment, the anti-collision mechanism 60 can be arranged on the casing 10 of the print head 100 and at least partially protrude from the outer surface of the casing 10. In this way, during the movement of the print head 100, the anti-collision mechanism 60 can detect whether it is in contact with the external structure by contact detection, for example, the anti-collision mechanism 60 can be configured as a pressure sensor or other contact detection mechanism. Since the anti-collision mechanism 60 protrudes from the outer surface of the casing 10, it can contact the external structure before the casing 10, so that the casing 10 can be stopped in time when the anti-collision mechanism 60 is triggered to avoid collision between the casing 10 and the external structure due to excessive movement.

[0139] Alternatively, in another embodiment, the anti-collision mechanism 60 can also detect the distance between the anti-collision mechanism 60 and the external structure by non-contact detection, for example, the anti-collision mechanism 60 can be configured as an infrared distance sensor or other non-contact detection mechanism. In this way, the casing 10 can be stopped in time when it is detected that the distance between the anti-collision mechanism 60 and the external structure is too close, so as to avoid collision between the casing 10 and the external structure due to excessive movement. The specific arrangement can be set as required and is not limited herein.

[0140] The utility model also proposes a kind of inkjet printing device 1000, the inkjet printing device 1000 includes print head 100, the specific structure of the print head 100 refers to above-mentioned embodiment, since the present inkjet printing device 1000 has adopted all technical solutions of above-mentioned all embodiments, at least has all beneficial effects brought by the technical solutions of above-mentioned embodiment, here no longer one by one elaboration.

[0141] In some embodiments, the inkjet printing device 1000 can also include a printing table 200, an ink supply module 300, a housing 700, an ink stack module, a rack 600, a drive assembly, etc., which are not listed one by one. The inkjet printing device 1000 also includes a housing 700, which forms a receiving space inside. The printing table 200, the ink supply module, and the print head 100 are located in the receiving space. The print head 100 is movably arranged on the rack 600 and connected to the drive assembly, so as to move under the driving action of the drive assembly. The ink stack module can cooperate with the print head to maintain the print head 100.

[0142] In some embodiments of the present application, the housing 700 can be provided with an opening 71a communicating with the receiving space. The opening 71a is located above the printing table 200. The housing 700 also includes a cover plate 71b, which can open or cover the opening 71a. The cover plate 71b can be transparent or translucent to facilitate direct observation of the printing inside through the cover plate 71b.

[0143] It should be noted that the inkjet printing device proposed in the present application can be a thermal inkjet printer, a piezoelectric inkjet printer, or a white ink painting printer, a white ink direct printing printer, etc. As long as it is a device used for spraying ink for printing operation.
