The manual cutting method is relatively troublesome, and if a cutting structure is provided in the inkjet printer, a translation assembly needs to be additionally provided to drive the cutting structure to move for cutting, and it is also easy to scratch the printing material when no cutting is needed.

[0050] Based on the above problems, the present application provides a cutting knife module 1 applied in an inkjet printer 100.

[0051] Please refer to Figure 1The inkjet printer 100 comprises a rack 20 as a mounting base, a print head 10 and a translation assembly 30 arranged on the rack 20, the rack 20 is provided with a printing platform for carrying a printing material, the print head 10 is provided with at least an ink ejection module 2, the print head 10 is in transmission cooperation with the translation assembly 30 and is located above the printing platform, the translation assembly 30 can drive the print head 10 to translate to different positions for inkjet printing. In some embodiments, the inkjet printer 100 can also be provided with a lifting assembly, the lifting assembly can drive the print head 10 to lift to adjust the printing height. Optionally, the print head 10 can also comprise but is not limited to an image acquisition module, a sensor and the like, and a cutter module 1 can also be arranged in the print head 10.

[0052] Please refer to Figures 4 to 6 In some embodiments of the utility model, the cutter module 1 comprises a support 11, a cutter assembly 12 and a driving mechanism 13, the cutter assembly 12 is swingably arranged on the support 11 and has a cutting position and a retracted position, when in the cutting position, the cutting part of the cutter assembly 12 protrudes from the support 11, when in the retracted position, the cutting part does not protrude from the support 11 or the part of the cutting part protruding from the support 11 is less than the part of the cutting part protruding from the support 11 when in the cutting position; the driving mechanism 13 is arranged on the support 11 and is in transmission cooperation with the cutter assembly 12, for driving the cutter assembly 12 to swing, so that the cutter assembly 12 reciprocally switches between the cutting position and the retracted position.

[0053] The cutter module 1 arranged in the inkjet printer 100 is used for cutting the printing material to cut out the printing material of the required size. In the cutter module 1, the support 11 is used as a base structure for mounting and supporting the cutter assembly 12 and the driving mechanism 13 and the like; optionally, the support 11 can be arranged as a plate structure, the cutter assembly 12 and the driving mechanism 13 are arranged on the plate surface of the support 11, or the support 11 can be arranged as a frame structure or a mounting shell, the cutter assembly 12 and the driving mechanism 13 are arranged in the mounting cavity 113 of the mounting shell. In addition, the support 11 can be a bearing structure specially arranged for mounting the cutter assembly 12 and the driving mechanism 13, that is, the cutter module 1 is modularly arranged and can be integrally disassembled. In some embodiments, the structure on the inkjet printer 100 can also be used as the support 11, for example, the print head 10 of the inkjet printer 100 is provided with the ink ejection module 2, the shell of the ink ejection module 2 can be used as the support 11, or the print head 10 is provided with the shell 3 for mounting the ink ejection module 2 and the printing module, the shell 3 is used as the support 11 to mount the cutter assembly 12 and the driving mechanism 13.

[0054] The cutter assembly 12 is a functional body for contacting the printing material to cut the printing material. The cutter assembly 12 is provided with a cutter 121, which can be provided as a round blade, a sharp blade or other structures, wherein the round blade is a circular blade provided with a circumferential cutting edge, and the sharp blade is a blade structure provided with a blade tip.

[0055] The cutter assembly 12 is swingably arranged on the support 11, i.e. the cutter assembly 12 is rotationally connected with the support 11, for example, the cutter assembly 12 is rotationally connected with the support 11 through a rotating shaft 15. The cutter assembly 12 can be driven by the driving mechanism 13 to swing relative to the support 11, so as to switch the cutter assembly 12 between a cutting position and a retracted position. When the cutter assembly 12 is in the cutting position, the cutting part of the cutter assembly 12 protrudes from the support 11. When the cutter assembly 12 is in the retracted position, the cutting part does not protrude from the support 11, or when the cutter assembly 12 is in the retracted position, the part of the cutting part protruding from the support 11 is less than that when the cutter assembly 12 is in the cutting position. For example, the support 11 has a mounting surface for mounting the cutter assembly 12. The cutter assembly 12 can swing on the mounting surface. When the cutter assembly 12 is in the cutting position, the cutting part protrudes from the edge of the mounting surface. When the cutter assembly 12 is in the retracted position, the cutting part can be retracted into the area of the mounting surface, or the part of the cutting part protruding from the edge of the mounting surface can be less than that when the cutter assembly 12 is in the cutting position. Alternatively, the support 11 is provided with a mounting cavity 113 and a first opening 114 communicating with the mounting cavity 113. When the cutter assembly 12 is in the cutting position, the cutting part protrudes from the first opening 114 into the mounting cavity 113. When the cutter assembly 12 is in the retracted position, the cutting part can be retracted into the mounting cavity 113, or the part of the cutting part protruding from the mounting cavity 113 can be less than that when the cutter assembly 12 is in the cutting position.

[0056] In a specific application, the cutter module 1 is arranged on the inkjet printer 100. The height of the cutting end of the cutter assembly 12 in the cutting position is lower than that in the retracted position. When the cutter assembly 12 is in the cutting position, the cutting end can contact the printing material to cut the printing material. When the cutter assembly 12 is in the retracted position, the cutter assembly 12 does not contact the printing material. In this way, when the printing material does not need to be cut, the cutter assembly 12 can be moved to the retracted position to avoid scratching the printing material. The cutter module 1 can be arranged on the print head 10. Since the cutter assembly 12 of the print module can be retracted, even if the inkjet module 2 and the print module move together, when inkjet printing is performed without cutting, the cutter assembly 12 can be swung to the retracted position to avoid scratching the printing material during printing. In this way, the number of components in the inkjet printer 100 can be reduced, and the structure of the inkjet printer 100 can be simplified.

[0057] Optionally, the driving mechanism 13 can be set as a motor or a rotary cylinder, the output shaft of the motor or the rotating part of the rotary cylinder is directly connected with the cutter assembly 12; or the output shaft of the motor or the rotating part of the rotary cylinder can be connected with the cutter assembly 12 through at least one transmission structure such as gear transmission structure, synchronous belt transmission structure and connecting rod transmission structure. In addition, the driving mechanism 13 can also be set as a telescopic cylinder, which can be connected with the cutter assembly 12 through at least one transmission structure such as gear and rack transmission structure and connecting rod transmission structure, or the cylinder and the cutter assembly 12 can also be driven and matched through the sliding groove 1221 structure in the following embodiments, and the specific implementation manner is described below.

[0058] Optionally, referring to Figure 2 and Figure 3 The cutter module 1 can be arranged on the print head 10, for example, the cutter module 1 is fixed on the inkjet module 2, or the cutter module 1 and the inkjet module 2 are installed on the same housing 3. Of course, in some embodiments, the cutter module 1 and the print head 10 can also be driven by different moving assemblies to move respectively.

[0059] That is, the present application sets a cutter module 1 applied in an inkjet printer 100, the cutter assembly 12 of the cutter module 1 is arranged to be swingable relative to the support 11, and the driving mechanism 13 is used to drive the cutter assembly 12 to rotate to switch the cutter assembly 12 between the cutting position and the retracted position. When the printed material needs to be cut, the driving mechanism 13 drives the cutter assembly 12 to swing to the cutting position, so that the cutter assembly 12 contacts the printed material, and the printed material can be cut by moving the cutter module 1; when the printed material does not need to be cut, the cutter assembly 12 is swung to the retracted position, so that the cutter assembly 12 does not contact the printed material to scratch the printed material.
