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

[0067] Therefore, based on the above considerations, the present invention proposes a print head 100. The print head 100 includes a housing 10, a printing module 20 and a cutter module 30, and the printing module 20 and the cutter module 30 are integrated in the housing 10, so that the print head 100 can have both pattern printing and printing material cutting functions, which is conducive to improving the practicality of the print head 100.

[0068] Next, the structure of the print head 100 proposed in this application is explained and illustrated by an embodiment. In the embodiment of the present invention, please refer to Figures 1 to 5 The print head 100 proposed in the present application includes a housing 10, a printing module 20 and a cutter module 30. A receiving cavity is formed in the housing 10. The housing 10 has a working surface 1111. A first opening 1111a connected to the receiving cavity is opened on the working surface 1111; the printing module 20 is arranged in the receiving cavity and is arranged opposite to the first opening 1111a so as to be exposed through the first opening 1111a; the cutter module 30 is arranged in the housing 10 and can protrude from the working surface 1111 to cut the printing material.

[0069] The housing 10 may be a hollow box structure, which is used to form a housing cavity for placing the printing module 20, so as to isolate and protect the functional module placed inside the housing 10, and improve the protection performance of the print head 100. The printing module 20 may be completely disposed in the housing cavity of the housing 10, or part of it may be disposed in the housing cavity and the other part may be disposed outside the housing cavity, which is not limited here. In some embodiments, the housing 10 may be in a rectangular parallelepiped shape, a cube shape, or other shapes.

[0070] Furthermore, one of the outer walls of the housing 10 is used to form a working surface 1111. By opening a first opening 1111a on the working surface 1111, the printing module 20 in the accommodating cavity can operate outward to print a preset pattern on the printing material.

[0071] In one embodiment of the present invention, the cutter module 30 may be arranged outside the housing 10. For example, the cutter module 30 may be installed on the outer wall of the housing 10, and at least a portion of the cutter module 30 may protrude from the working surface 1111. Alternatively, a groove may be provided on the working surface of the housing, and the cutter module 30 may be accommodated in the groove, and at least a portion of the cutter module 30 may protrude from the notch of the groove to protrude from the working surface 1111. Of course, the cutter module 30 may also be arranged at other locations outside the housing 10, which is not limited here.

[0072] See also Figures 1 to 6 In another embodiment of the present invention, a second opening 1111b connected to the accommodating cavity is provided on the working surface 1111, and the second opening 1111b and the first opening 1111a are arranged at intervals. The cutter module 30 is arranged in the accommodating cavity and is arranged opposite to the second opening 1111b so as to be exposed through the second opening 1111a. That is, in this embodiment, the cutter module 30 can be arranged in the accommodating cavity of the housing 10, and by providing the second opening 1111b on the working surface 1111, the cutter module 30 in the accommodating cavity can operate outward to cut the printed material printed with a preset pattern.

[0073] The working surface 1111 may be a plane formed at the bottom of the housing 10, and the shape of the first opening 1111a or the second opening 1111b may be a rectangular parallelepiped, a cube, or other shapes, which are not limited here. Optionally, the shape of the first opening 1111a may be configured to conform to the printing module 20, and the shape of the second opening 1111b may be configured to conform to the cutting module 30, so as to facilitate the positioning and assembly of the housing 10 with the printing module and the cutting module 322, respectively.

[0074] See also Figures 1 to 5In an embodiment of the present invention, the cutter module 30 includes a driving mechanism 31 and a cutter assembly 32, the driving mechanism 31 is arranged in the accommodating cavity; the cutter assembly 32 is transmission-connected with the driving mechanism 31 so that the cutter assembly 32 can move relative to the second opening 1111a; the cutter assembly 32 has a working state and a storage state. When in the working state, the cutter assembly 32 at least partially extends out of the second opening 1111a, and when in the storage state, the cutter assembly 32 is retracted into the accommodating cavity.

[0075] It should be noted that the inkjet printing device includes a driving device disposed outside the print head 100, and the print head 100 can be in transmission connection with the driving device. During use, the print head 100 can be driven by the driving device to move relative to the printing material to move to a corresponding position of the printing material, and the printing module 20 or the cutter module 30 can be used to print patterns on the printing material and cut the printing material.

[0076] When the step of pattern printing is performed, the working surface 1111 of the print head 100 and the printing material are arranged relative to each other in the vertical direction, and the printing module 20 can perform inkjet printing on the printing material below it. At the same time, the cutter module 30 can be movably arranged relative to the second opening 1111b. Therefore, when the print head 100 performs the step of pattern printing, the cutter assembly 32 can be kept in the storage state retracted to the accommodating cavity to prevent the cutter 322 from damaging the printing material during the printing process of the print head 100, thereby affecting the processing effect of the print head 100.

[0077] After completing the step of printing a pattern on the printing material, the printing module 20 stops inkjet printing on the printing material, and at the same time, the cutter assembly 32 switches to a working state in which it at least partially extends out of the second opening 1111b, so that the printing material on which the pattern printing has been completed can be cut by the part of the cutter assembly 32 extending out of the second opening 1111b.

[0078] See also Figure 6 and Figure 8 In one embodiment of the present invention, the driving mechanism 31 includes a rotating portion 311, one end of which is arranged opposite to the second opening 1111b and connected to the cutter assembly 32, and is used for rotating relative to the second opening 1111b to drive the cutter assembly 32 to rotate closer to or away from the second opening 1111b.

[0079] The rotating part 311 is a mechanism for providing power to the cutter assembly 32 to drive the cutter assembly 32 to rotate toward or away from the second opening 1111b. The rotating part 311 can provide power in a purely mechanical drive manner or in an electric drive manner. For example, the rotating part 311 can be, but is not limited to, an electric drive structure such as a rotating motor. The specific selection can be made by those skilled in the art.

[0080] Among them, the rotating part 311 can be directly connected to the cutter assembly 32 to drive the cutter assembly 32 to rotate relative to the second opening 1111b; the rotating part 311 can also be indirectly connected to the cutter assembly 32 through a transmission structure to drive the cutter assembly 32 to rotate by driving the transmission structure to move.

[0081] See also Figure 8 In some embodiments, the rotating part 311 may specifically include a driving member 3111 and a transmission member 3112. Specifically, the driving member 3111 is spaced apart and arranged at one side of the cutter assembly 32; the transmission member 3112 is rotatably arranged and includes a first connection end 3112a and a second connection end 3112b arranged opposite to each other. The first connection end 3112a of the transmission member 3112a is transmission-connected to the output end of the driving member 3111, and the second connection end 3112b is connected to the cutter assembly 32.

[0082] Driven by the driving member 3111, the second connecting end 3112b of the transmission member 3112 can rotate forward toward the second opening 1111b to drive the cutter assembly 32 to extend toward the second opening. The second connecting end 3112b can also rotate backward away from the second opening 1111b under the drive of the driving member 3111 to drive the cutter assembly 32 to retract toward the second opening 1111b.

[0083] See also Fig. 9 In another embodiment of the present invention, the driving mechanism 31 includes a translation portion 312, one end of which is arranged opposite to the second passage 1111b and connected to the cutter assembly 32, and is used for translational movement relative to the second passage 1111b to drive the cutter assembly 32 to move toward or away from the second passage 1111b.

[0084] The translation part 312 is a mechanism for providing power to the cutter assembly 32 to drive the cutter assembly 32 to move linearly toward or away from the second port 1111b. The translation part 312 can provide power in a purely mechanical drive manner or in an electric drive manner. For example, the translation part 312 can be, but is not limited to, an electric drive structure such as a linear motor or a linear module. The specific selection can be made by those skilled in the art.

[0085] Among them, the translation part 312 can be directly connected to the cutter assembly 32 to drive the cutter assembly 32 to translate toward or away from the second opening 1111b; the translation part 312 can also be indirectly connected to the cutter assembly 32 through a transmission structure to drive the cutter assembly 32 to translate by driving the transmission structure to move.

[0086] In some embodiments, the translation portion 312 may specifically include a push member 3121 and an elastic member 3122. Specifically, the push member 3121 is movably disposed on one side of the cutter assembly 32 and has an extended position and a retracted position. When the push member 3121 is in the extended position, it is used to abut against the cutter 322 to drive the cutter assembly 32 to be in the extended state. When the push member 3122 is in the extended position, it is used to disengage from the abutment with the cutter 322. The elastic member 3122 is elastically connected to the cutter assembly 32 and is used to drive the cutter assembly 32 to return to the retracted state when the push member 3121 is in the retracted position.

[0087] Among them, the push member 3122 can be set as an electric drive structure; or, the print head 100 is set to have an ejection stroke moving in the forward direction along the first direction and a reset stroke moving in the reverse direction of the first direction, and the push member is configured to be movably set along the first direction, for abutting against a collision block outside the print head 100 and moving to an extended position when the print head 100 completes the ejection stroke, so as to drive at least part of the cutter assembly 32 to extend out of the second opening 1111b, or for abutting against another collision block outside the print head 100 and moving to a retracted position when the print head 100 completes the reset stroke, so as to drive the cutter assembly 32 to retract into the second opening 1111b.

[0088] Of course, the technical solution of the present invention is not limited thereto. In some embodiments, the driving mechanism 31 may include a variety of driving structures, which may be configured as the rotating portion 311 and the translating portion in the aforementioned embodiment, so that the cutter assembly 32 can rotate or translate relative to the second opening 1111b along multiple axis directions under the drive of the driving mechanism 31, thereby improving the freedom of movement of the cutter assembly 32. The specific implementation method can be set according to actual needs and is not limited here.

[0089] See also Figures 6 to 9 In an embodiment of the present invention, the cutter assembly 32 includes a frame 321 and a cutter 322, one end of the frame 321 is transmission-connected to the driving mechanism 31; the cutter 322 is disposed at one end of the frame 321 away from the driving mechanism 31 and is detachably connected to the frame 321.

[0090] The frame 321, as a fixed structure for mounting the cutter 322, can be connected to the driving mechanism 31 in a transmission manner, so that the cutter 322 can be driven to telescopically move relative to the second opening 1111b under the drive of the driving mechanism 31. Since the cutter 322 is detachably connected to the frame 321, and the cutter assembly 32 is arranged opposite to the second opening 1111b, the user can assemble the cutter 322 to the frame 321 or disassemble it from the frame 321 through the second opening 1111b without removing the housing 10, thereby improving the convenience of assembly and disassembly of the cutter 322.

[0091] In this embodiment, the frame 321 can also be provided with a limiting groove 3211, and part of the cutter 322 can be inserted into the limiting groove 3211, so that the limiting effect of the limiting groove 3211 on the cutter 322 can be used to achieve quick positioning of the cutter 322 and the frame 321, and the connection stability between the cutter 322 and the frame 321 can be improved.

[0092] In an embodiment of the present invention, the frame 321 is provided with a mounting position; the cutter assembly 32 also includes a magnetic member 324, which is provided at the mounting position to magnetically cooperate with the cutter 322; and / or, the cutter assembly 32 also includes a fastener 325, and the mounting position is provided with a fastening hole for the fastener 325 to pass through, so that the cutter 322 can be locked to the frame 321 through the fastener 325.

[0093] It should be noted that the cutter 322 can be detachably connected to the frame 321 only by magnetic attraction. For example, the cutter 322 can be directly magnetically matched with the magnetic member 324 provided at the mounting position, or another magnetic member 324 can be provided at one end of the cutter 322 facing the frame 321, so that the cutter can be mounted to the frame 321 by magnetic attraction of the two magnetic members. Alternatively, the cutter 322 can be locked to the frame 321 only by the fastener 325, wherein the fastener 325 can be configured as a bolt, the fastening hole can be configured as a threaded hole, and the fastener 325 can penetrate the cutter 322 and be threadedly connected to the frame 321, so that the cutter 322 is locked to the frame 321. Of course, the cutter 322 can also be detachably mounted to the frame 321 by other methods, which are not limited here. Furthermore, in some embodiments, the cutter 322 can be simultaneously installed to the frame 321 by two or more detachable connection methods. For example, on the basis of the magnetic connection between the cutter 322 and the frame 321, the cutter 322 can be further locked to the frame 321 by a fastener 325. In this way, the connection stability between the frame 321 and the cutter 322 can be further improved.

[0094] See also Figure 8In an embodiment of the present invention, the cutter assembly 32 further includes a material pressing piece 323, which is disposed on one side of the cutter assembly 32. When the cutter assembly 32 is in an extended state, the material pressing piece 323 extends out of the second opening 1111b, and the material pressing piece 323 is used to press the printing material.

[0095] It is understandable that by providing a material pressing piece 323 on one side of the cutter assembly 32, when the cutter 322 cuts the printed material, the material pressing piece 323 can press the printed material from the side of the cutter 322 through its outer peripheral surface to prevent the printed material from warping and affecting the printed material cutting effect of the cutter assembly 32. The material pressing piece 323 can be a wheel structure, with its central axis direction perpendicular to the cutting surface of the cutter 322, so that the material pressing piece 323 can roll relative to the printed material without scratching the printed material; of course, the material pressing piece 323 can also be set to other shapes, which are not limited here.

[0096] Further, in the embodiment of the present invention, the cutter assembly 32 includes a frame 321 and a cutter 322, and the material pressing piece 323 and the cutter 322 are arranged side by side on the frame 321. Such arrangement, on the one hand, can facilitate the material pressing piece 323 to be arranged adjacent to the cutter 322, so that the material pressing piece 323 can have a good pressing effect on the cut printing material part when the cutter 322 cuts the printing material; on the other hand, the cutter 322 and the material pressing piece 323 can be connected to form an integral structure through the frame 321, so that only one driving mechanism 31 is required to drive the frame 321 to move relative to the second port 1111b, so as to drive the cutter 322 and the material pressing piece 323 to move synchronously relative to the second port 1111b.

[0097] In this embodiment, the side wall of the frame 321 can be protrudingly provided with a surrounding structure 3212, which is arranged at the end of the pressing piece 323 away from the second opening 1111b, and is arranged around the side of the pressing piece 323. In this way, the side wall of the surrounding structure 3212 can be limited by the outer peripheral surface of the pressing piece 323 to achieve quick positioning of the pressing piece 323 and the frame 321, and the connection stability between the pressing piece 323 and the frame 321 can be improved.

[0098] Further, the pressing piece 323 can be detachably connected to the frame 321 to facilitate maintenance or replacement of the pressing piece 323. Specifically, the pressing piece 323 can be detachably connected to the frame 321 by magnetic attraction, or by threaded connection, which is not limited here.

[0099] In a feasible implementation manner, as described in the above embodiment, the cutter assembly 32 further includes a fastener 325, and the mounting position is provided with a fastening hole for the fastener 325 to pass through. The cutter 322 and the press 323 can be locked to the frame 321 by the same fastener 325.

[0100] Specifically, the fastener 325 can be configured as a bolt, the fastening hole can be configured as a threaded hole, and the fastener 325 can sequentially penetrate the cutter 322 and the pressing piece 323 and be threadedly connected to the frame 321, so that the cutter 322 and the pressing piece 323 can be locked on the frame 321 through the same fastener 325. Of course, the cutter 322 and the pressing piece 323 can also be fixedly matched with the frame 321 through different fasteners 325, so that the cutter 322 or the pressing piece 323 can be disassembled and assembled separately according to the use requirements.

[0101] Of course, in some embodiments, the pressing piece 323 can also be set 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 to drive the cutter 322 and the pressing piece 323 to move respectively, which is not limited here.

[0102] See also Figure 6 and Figure 7 In one embodiment of the present invention, the cutter module 30 also includes a cutter housing 33, a mounting cavity is formed in the cutter housing 33, and an outer wall of the cutter housing 33 is provided with an avoidance opening 3311 connected to the mounting cavity, and the avoidance opening 3311 and the second opening 1111b are arranged opposite to each other so as to be exposed through the second 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 a working state, the cutter assembly 32 at least partially extends out of the second opening 1111b through the avoidance opening 3311.

[0103] It can be understood that by setting up the cutter housing 33, the functional components such as the drive mechanism 31 and the cutter assembly 32 of the cutter module 30 can be integrated in the installation cavity formed in the cutter housing 33 to achieve a modular setting, which is conducive to improving the assembly convenience of the cutter module 30.

[0104] The cutter housing 33 may be a box structure with a hollow interior, and it may also isolate and protect the functional components such as the drive mechanism 31 and the cutter assembly 32 placed in the installation cavity. In some embodiments, the cutter housing 33 may be a rectangular parallelepiped, a cube, or other shapes.

[0105] See also Figure 6 and Figure 7In one embodiment of the present invention, the cutter housing 324 includes a main body portion 33a and a clamping portion 33b connected in sequence, the main body portion 33a is arranged in the accommodating cavity and is arranged opposite to the second opening 1111b; one end of the clamping portion 33b is connected to the main body portion 33a, and the other end extends toward the second opening 1111b, the clamping portion 33b is at least partially clamped with the second opening 1111b to be exposed through the second opening 1111b, and an avoidance opening 3311 is provided on one side of the clamping portion 33b exposed at the second opening.

[0106] Such arrangement allows at least a portion of the cutter housing 33 to engage with the second opening 1111b on the housing 10, thereby facilitating quick positioning of the cutter module 30 and the housing 10 and thereby improving the assembly stability of the cutter module 30.

[0107] Specifically, see Figure 8 In one embodiment of the present invention, the cutter housing 33 is composed of a rear shell 331 and a front cover 332, wherein a mounting space with an opening on one side is formed in the rear shell 331, and the front cover 332 can be opened and closed to cover the opening of the rear shell 331, so as to enclose the rear shell 331 to form a mounting cavity. The rear shell 331 and the front cover 332 can be detachably connected. In addition, the bottom end of the rear shell 331 is arranged opposite to the second opening 1111b, and the end surface of the bottom end is provided with an avoidance opening 3311 connected to the mounting cavity, and at least part of the cutter assembly 32 can extend from the mounting cavity through the avoidance opening 3311 to the second opening 1111b, so as to realize the function of cutting printed materials.

[0108] See also Figures 1 to 5 In one embodiment of the present invention, two first openings 1111a are spaced apart on the working surface 1111, two printing modules 20 are provided, each printing module 20 is provided with a corresponding first opening 1111a, and the cutter module 30 is provided between the two printing modules 20, or the cutter module 30 is provided 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 heat transfer printer, and the DTF ink used by it is usually composed of CMYK4 colors and white. Correspondingly, the print head 100 is provided with two printing modules 20, one of which is a color ink printing module, which is used to realize the color ink printing function corresponding to CMYK4 colors; the other printing module 20 is a white ink printing module, which is used to realize the white ink printing function. During use, the print head 100 can first print a color pattern on the printing material through one of its printing modules 20, and then print a layer of white ink on the color pattern through the other printing module 20. In this way, by printing white ink on the printing material, the color of the printed color pattern can be made more vivid.

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

[0111] In another embodiment, the two printing modules 20 may also be closely arranged, and the cutter module 30 may be arranged on the side of one of the cutter modules 30 away from the other 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, so that the printing material can be connected with the color ink printing module, the white ink printing module and the cutter module 30 in sequence during the transmission process to complete the color ink printing, white ink printing and printing material segmentation steps in sequence. In addition, since the printing material needs to be transferred to a baking machine or a curing machine after completing the pattern printing and printing material segmentation steps to perform the subsequent printing material drying steps, and the inkjet printing device and the baking machine or the curing machine are generally connected 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 are arranged in sequence along the transmission direction of the printing material, which also facilitates the transfer of the segmented printing material to the baking machine or the curing machine.

[0112] See also Figures 1 to 5 In an embodiment of the present invention, the housing 10 includes a main shell 11 and a connecting member 12. The main shell 11 is provided with a accommodating cavity, and a working surface 1111 is formed at one end of the main shell 11; one end of the connecting member 12 is provided on the outer wall of the main shell 11, and the other end extends in a direction away from the main shell 11, and is used for an external driving device to drive the print head 100 to move under the drive of the driving device.

[0113] In this embodiment, the main housing 11 may be provided in an integral structure, which is formed by integral injection molding or integral die casting; or, the main housing 11 may be split into a plurality of housing components and assembled from the plurality of housing components.

[0114] See also Figure 5In a feasible embodiment, the main shell 11 includes a bottom shell 111 and a cover body 112, and a storage space with a top opening is formed in the bottom shell 111 for placing components such as a printing module and a cutter 322 module. The bottom shell 111 also has a working surface 1111 formed at its bottom end, and a first opening 1111a and a second opening 1111b are provided on the working surface 1111 and are arranged on the bottom wall of the bottom shell 111. The bottom shell 111 can be in the shape of a rectangular parallelepiped, a cube or other shapes. The cover body 112 is arranged above the bottom shell 111, and covers the opening at the top of the bottom shell 111, and is enclosed with the bottom shell 111 to form a storage cavity. By providing the cover body 112 to cover the opening, the various functional modules placed inside the storage cavity can be isolated and protected.

[0115] The connecting member 12 is a plate structure, one end of which is connected to the outer wall of the main housing 11, specifically, it can be fixedly connected to the outer wall of the bottom shell 111, or it can be fixedly connected to the outer part of the cover body 112, and the other end protrudes toward the side of the main housing 11. By connecting the connecting member 12 to an external drive device, the drive device can drive the connecting member 12 to drive the print head 100 to move relative to the printing material, so that the print head 100 can process different positions of the printing material. Furthermore, the connecting member 12 also has a bearing surface 121 formed on the top thereof, so that the connecting member 12 can play a role in connecting with the external drive device and can also play a role in supporting some components of the print head 100.

[0116] See also Figure 2 and Figure 3 In an embodiment of the present invention, the print head 100 also includes a main board 40, which is disposed in the accommodating cavity and connected to a cavity wall on one side of the accommodating cavity facing the connecting member 12; the main shell 11 includes a heat dissipation portion 1112, which is located on a side of the main shell 11 facing the connecting member 12 and is arranged to avoid the connecting member 12, and at least a portion of the main board 40 abuts against the heat dissipation portion 1112 to dissipate heat through the heat dissipation portion 1112.

[0117] Among them, the main shell 11 can be connected to a heat sink on its outer wall to form a heat sink 1112, and the heat sink can be but is not limited to being set as a heat sink; the main shell 11 can also be provided with a plurality of array-arranged protrusion structures on the side away from the main board 40, thereby forming heat sink fins through the main shell 11's own structure, thereby forming the heat sink 1112 of the main shell 11.

[0118] Furthermore, at least part of the connecting member 12 is flush with the heat dissipation portion 1112 in height. On this basis, an avoidance groove can be provided in the area corresponding to the heat dissipation portion 1112 on the side of the connecting member 12 facing the main housing 11, and the heat dissipation portion 1112 is provided in the avoidance groove, so that the heat dissipation portion 1112 and the connecting member 12 can be arranged to avoid each other. Of course, the heat dissipation portion 1112 and the connecting member 12 can also be arranged to be staggered in the height direction to achieve mutual avoidance between the heat dissipation portion 1112 and the connecting member 12, which is not limited here.

[0119] Further, in order to improve the heat dissipation effect, the main housing 11 is further provided with heat dissipation holes 1113 in the area corresponding to the mainboard 40. For example, see Figure 1 One or more heat dissipation holes 1113 may be respectively provided at the positions on both sides of the main housing 11 corresponding to the mainboard 40. The heat dissipation holes 1113 are connected to the accommodating cavity in the main housing 11 to ventilate and dissipate heat for the mainboard 40 and other components in the accommodating cavity.

[0120] See also Figures 1 to 5 In an embodiment of the present invention, the housing 10 further includes a mounting member 13, one end of the mounting member 13 is disposed on a side of the main housing 11 away from the connecting member 12, and the other end extends in a direction away from the main housing 11; the print head 100 further includes a camera module 50, which is mounted on the mounting member 13.

[0121] It can be understood that by setting a camera module 50 on the print head 100 to photograph the printing path of the print head 100, it is possible to detect whether the printing path of the print head 100 is a straight line, and the printing position of the print head 100 can be further calibrated based on the detection result, which is beneficial to ensure the printing quality of the print head 100.

[0122] In one embodiment of the present application, the mounting member 13 and the connecting member 12 are disposed on opposite sides of the main housing 11, and the connecting member 12 is transmission-connected to an external driving device, which can drive the print head 100 to translate along a direction perpendicular to the arrangement of the mounting member 13 and the connecting member 12. This arrangement can reduce the volume of the print head 100 in a direction perpendicular to the arrangement of the mounting member 13 and the connecting member 12, so that the print head 100 can have sufficient transfer space.

[0123] The mounting member 13 may be a box structure with a hollow interior, in which an inner cavity for accommodating the camera module 50 is formed, and the inner cavity may be connected to the accommodating cavity of the main shell 11, and the outer wall of the mounting member 13 is provided with a through hole connected to the inner cavity, so that the camera module 50 can shoot and detect outward through the through hole; or, the mounting member 13 may be a plate structure for fixing the camera module 50, and the camera module 50 may be fixed to the bottom of the plate structure. The mounting member 13 may be set separately from the main shell 11, and its material may be the same as that of the main shell 11, or different from that of the main shell 11. For example, the mounting member 11 may be set as a sheet metal material to ensure its structural strength, or the mounting member may be set as a plastic material to reduce the preparation cost of the housing 10 and help reduce the weight of the housing 10. By making the mounting member 13 separate from the main housing 11, when the mounting member 13 has a complex structure, it can be processed and formed separately to reduce the difficulty of producing the housing 10; alternatively, the mounting member 13 and the main housing 11 can be integrally provided to improve the stability of the overall structure of the print head 100.

[0124] In an embodiment of the present invention, at least part of the main housing 11 is made of plastic material. It should be noted that in the related art, the material of the housing 10 of the print head 100 is usually set to sheet metal material. In comparison, the technical solution of the present invention is conducive to reducing the weight of the housing 10 by making at least part of the main housing 11 of plastic material, so that the external drive device drives the print head 100, so that the speed adjustment of the print head 100 can have more margin. In addition, the selection of plastic material is also conducive to reducing the preparation cost of the housing 10.

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

[0126] See also Figure 10 to Figure 11 In an embodiment of the present invention, the printing module 20 includes an inkjet mechanism 21, an ink supply mechanism 22 and a leakage prevention mechanism. The inkjet mechanism 21 is arranged at the first port 1111a; the ink supply mechanism 22 is detachably connected to the inkjet mechanism 21 to transport ink to the inkjet mechanism 21; the leakage prevention mechanism is connected between the inkjet mechanism 21 and the ink supply mechanism 22, and is used to prevent the ink in the ink supply mechanism 22 from leaking when the ink supply mechanism 22 and the inkjet mechanism 21 are separated.

[0127] The ink supply mechanism 22 may be a color ink supply mechanism, such as a color ink bag, or a white ink supply mechanism, such as a white ink bag. The inkjet mechanism 21 may be configured as a nozzle for printing the ink provided by the ink bag on the printing material in an inkjet printing manner.

[0128] In one embodiment of the present application, the ink supply mechanism 22 and the inkjet mechanism 21 can be connected by plugging and matching, so that the ink supply mechanism 22 and the inkjet mechanism 21 can be quickly plugged and unplugged, thereby improving the assembly convenience of the printing module 20. Of course, the ink supply mechanism 22 and the inkjet mechanism 21 can also be detachably connected by snap connection, thread connection, or other methods, which are not limited here.

[0129] It should be noted that in a printing module 20, a plurality of ink supply mechanisms 22 may be provided, and the plurality of ink supply mechanisms 22 are connected side by side to the inkjet mechanism 21. In order to improve the connection stability between the film supply mechanism and the inkjet mechanism 21, a plurality of positioning grooves 211 may be provided on the inkjet mechanism 21, and the shape of the positioning grooves 211 is configured to imitate the inkjet mechanism 21, and each positioning groove 211 is used to cooperate with an inkjet mechanism 21 in a limited position. Of course, the inkjet mechanism 21 may also limit the ink supply mechanism 22 by other positioning structures, which are not limited here. The number of nozzles in the inkjet mechanism 21 may be consistent with the ink supply mechanism 22.

[0130] The film supply mechanism is detachably connected to the inkjet mechanism 21, that is, after the film supply mechanism is installed on the inkjet mechanism 21, it can be separated and removed to facilitate the maintenance and replacement of various structures of the printing module 20. On this basis, by connecting the anti-leakage mechanism between the inkjet mechanism 21 and the ink supply mechanism 22, it can be prevented that when the anti-leakage mechanism is removed from the inkjet mechanism 21, the ink in the ink supply mechanism 22 leaks outward and directly enters the accommodating cavity, causing contamination to other structures of the print head 100.

[0131] Among them, the leakage prevention mechanism can be specifically configured as a leakage prevention valve. When the film supply mechanism is connected to the inkjet mechanism 21, the leakage prevention valve opens to connect the ink path of the ink supply mechanism 22 and the inkjet mechanism 21; when the film supply mechanism is separated from the inkjet mechanism 21, the leakage prevention valve closes to stop the ink supply mechanism 22 from discharging ink.

[0132] In a feasible embodiment, the inkjet printing device can be a white ink heat transfer printer. Correspondingly, among the two printing modules 20 of the print head 100, one of the printing modules 20 is provided with four ink supply mechanisms 22, which are specifically configured as four color ink capsules corresponding to the four colors of CMYK; 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 capsules. 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, by printing white ink on the printing material, the color of the printed color pattern can be made more vivid.

[0133] Furthermore, in some embodiments, when the four ink supply mechanisms 22 in the printing module 20 are all white ink capsules, the four white ink capsules can be designed as a four-in-one, that is, the four white ink capsules are connected to form an integrated structure. In this way, the four white ink capsules can be disassembled and assembled with the inkjet mechanism 21 as a whole, which is conducive to improving the structural integration and disassembly convenience of the printing module 20.

[0134] See also Figure 2 and Fig.10 In some embodiments, the printing module 20 also includes an adapter plate 23, which can be electrically connected to the inkjet mechanism 21, and the input interface of the adapter plate 23 can be electrically connected to the main board 40. The adapter 23 can connect multiple nozzles in the inkjet structure 21. Therefore, when assembling the printing module 20, only one cable is required to connect the main board 4017 and the adapter plate 23 together, without setting multiple cables to connect the main board and multiple nozzles. The wiring is more convenient and the assembly is simpler.

[0135] See also Figure 1 and Figure 2 In the embodiment of the present invention, the print head 100 further includes an anti-collision mechanism 60, which is disposed on the housing 10 to prevent the housing 10 from being impacted from the outside. It can be understood that by providing the anti-collision mechanism 60 on the print head 100 to prevent the housing 10 from being impacted from the outside, the safety of the print head 100 can be improved.

[0136] Among them, the anti-collision mechanism 60 can be set on the side of the housing 10 to prevent the outer wall of the print head 100 from colliding with the external structure. For example, the print head 100 can move in the first direction, and the anti-collision mechanism 60 can be set on the opposite sides of the print head 100 along the first direction, so as to avoid the risk of the housing 10 being hit by the outside when the print head 100 moves in the first direction; or, the anti-collision mechanism 60 can also be set at the bottom of the housing 10 to prevent the printing surface at the bottom of the print head 100 from colliding with the external structure, and thereby achieve the effect of preventing the hand from being pinched; or, the anti-collision mechanism 60 can also be set on the side and bottom of the housing 10, so as to improve the comprehensiveness of the protection of the print head 100. Of course, the anti-collision mechanism 60 can also be used to realize the anti-collision function of other positions of the housing 10; the number of anti-collision mechanisms 60 provided on the housing 10 can be one, or two or more. That is, the present application does not limit the setting position and number of the anti-collision mechanism 60.

[0137] Furthermore, when the anti-collision mechanism 60 is provided on the side and the bottom of the housing 10, the anti-collision mechanism 60 provided on the side and the bottom of the housing 10 can be integrated into one, which is helpful to reduce the number of parts on the print head 100, so as to improve the structural integration and assembly efficiency of the print head 100.

[0138] In one embodiment, the anti-collision mechanism 60 can be specifically arranged on the housing 10 of the print head 100, and at least partially protrude from the outer surface of the housing 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 an external structure by means of 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 housing 10, it can contact the external structure before the housing 10, so that the housing 10 can be braked in time when the anti-collision mechanism 60 is triggered to avoid excessive movement of the housing 10 and collision with the external structure.

[0139] Alternatively, in another embodiment, the anti-collision mechanism 60 can also detect the distance between it 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, when it is detected that the distance between the anti-collision mechanism 60 and the external structure is too close, the housing 10 can be braked in time to avoid excessive movement of the housing 10 and collision with the external structure. The specific configuration can be as needed and is not limited here.

[0140] The present invention also proposes an inkjet printing device 1000, which includes a print head 100. The specific structure of the print head 100 refers to the above embodiment. Since the inkjet printing device 1000 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0141] In some embodiments, the inkjet printing device 1000 may further include a printing station 200, an ink supply module 300, a housing 700, an ink stack module, a frame 600, a drive assembly, etc., which are not listed one by one here. The inkjet printing device 1000 also includes a housing 700, and a receiving space is formed in the housing 700. The printing station 200, the ink supply module, and the print head 100 are arranged in the receiving space. The print head 100 is movably arranged on the frame 600 and connected to the drive assembly to move under the driving action of the drive assembly. The ink stack module can cooperate with the print head to achieve maintenance of the print head 100.

[0142] In some embodiments of the present application, the housing 700 may be provided with an opening 71a connected to the receiving space, the opening 71a is located above the printing table 200, and the housing 700 further includes a cover plate 71b, which may open or cover the opening 71a. The cover plate 71b may be transparent or semi-transparent, so that the printing situation inside can be directly observed through the cover plate 71b.

[0143] It should be noted that the inkjet printing device proposed in this application can be a thermal inkjet printer, a piezoelectric inkjet printer, or a white ink heat transfer printer, a white ink direct jet printer, etc., as long as it is a device used for jetting ink to perform printing operations. The printing material used for printing by the inkjet printing device can be configured as paper, film, cloth, etc., which is not limited here.

[0144] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
