[0062] Please refer to Figure 4 and Figure 8 In some embodiments of the present application, the connecting bracket 11 is provided with a limiting groove 114, and the magnetic attraction member 13 is arranged in the limiting groove 114. By such arrangement, the magnetic attraction member 13 is limitedly installed in the limiting groove 114, the position is stable, the combination strength is high, and the connecting bracket 11 can also protect the magnetic attraction member 13. Optionally, the limiting groove 114 can be located on the side of the mounting groove 111, or the limiting groove 114 can be located on the side of the mounting groove 111 away from the cutting end of the cutter 12 in the following embodiments.

[0063] Please refer to Figure 4 and Figure 8 In an embodiment, the limiting groove 114 is located on the side of the mounting groove 111 away from the cutting end.

[0064] In the embodiment, the magnetic attraction member 13 is installed on the side of the cutter 12 away from the cutting end, so that the direction of the magnetic attraction force acting on the cutter 12 is the same as the direction of the cutter 12 inserted into the mounting groove 111, which can utilize the magnetic attraction force to make the cutter 12 slide into the mounting groove 111 when the cutter 12 is installed, or can increase the magnetic attraction force acting on the cutter 12 in the direction of insertion and pulling out, thereby reducing the risk of the cutter 12 sliding out of the mounting groove 111.

[0065] Please refer to Figure 6In an embodiment, the installation groove 111 is in communication with the limiting groove 114, and the cutter 12 abuts against the magnetic member 13. In this arrangement, the distance between the magnetic member 13 and the cutter 12 is short, the magnetic force acting on the cutter 12 is increased, and the stability of the cutter 12 is improved, so that the cutter 12 is less likely to slide out of the installation groove 111.

[0066] Referring to Figure 4 In an embodiment, the cutter assembly 1 further comprises a pressing member 14, which is arranged on the connecting bracket 11 and located at one side of the cutter 12. The pressing member 14 extends out of the connecting bracket 11 and in the same direction as the cutter 12.

Alternatively, a connecting hole can be provided on the connecting bracket 11, and the connecting shaft 15 is inserted into the connecting hole and fixed by a shaft hole tight fit or bonded to the connecting hole. Optionally, the pressing member 14 can be provided as a rolling member, and the pressing member 14 is rotatably connected to the connecting shaft 15, so that the pressing member 14 can rotate relative to the connecting bracket 11, and the roller can roll on the surface of the printing material when cutting the printing material. For example, a bolt roller bearing can be provided, which includes a bolt, a bearing outer ring and a bearing inner ring rotatable relative to each other, the bolt is inserted into the bearing inner ring and fixedly connected to the bearing inner ring, which can be a tight fit or bonded, and the bolt serves as the connecting shaft 15 connected to the connecting bracket 11, and the bearing outer ring serves as the pressing member 14. Optionally, a soft rubber sleeve can be provided on the bearing outer ring.

[0074] In addition, in some embodiments, the connecting shaft 15 can also be rotatably connected to the connecting bracket 11, and the pressing member 14 can also be rotatable relative to the connecting bracket 11, so that the roller can also roll on the surface of the printing material when cutting the printing material.

[0075] Please refer to Figure 7 In an embodiment, the cutter assembly 1 further includes a fixing member 16 provided on the connecting bracket 11, and the connecting shaft 15 is connected to the fixing member 16 to fix the pressing member 14 to the connecting bracket 11.

[0076] In the present embodiment, the fixing member 16 can be provided as a nut, and the connecting shaft 15 is screwed to the nut to fix the pressing member 14 to the connecting bracket 11. Optionally, the pressing member 14 can be provided as a rolling member, and the pressing member 14 is rotatably connected to the connecting shaft 15, so that the pressing member 14 can rotate relative to the connecting bracket 11, and the roller can roll on the surface of the printing material when cutting the printing material. For example, a bolt roller bearing can be provided, which includes a bolt, a bearing outer ring and a bearing inner ring rotatable relative to each other, the bolt is inserted into the bearing inner ring and fixedly connected to the bearing inner ring, which can be a tight fit or bonded, and the bolt serves as the connecting shaft 15 connected to the fixing member 16, and the bearing outer ring serves as the pressing member 14.

[0077] In addition, the fixing member 16 can also be a bearing, for example, a rolling bearing, the outer ring of the bearing is fixed on the connecting support 11, and the connecting shaft 15 is connected with the inner ring of the bearing, for example, interference fit or bonding, so that the connecting shaft 15 is rotatably connected with the connecting support 11, so that the pressing member 14 is rotatably arranged. Of course, the fixing member 16 can also be a shaft sleeve or other structure, which is not limited here.

[0078] Optionally, the connecting shaft 15 can be arranged in different areas of the cutter 12, or a structure such as a clearance 121 can be arranged on the cutter 12, so that the connecting shaft 15 is arranged in the clearance 121, which is not limited here.

[0079] In combination with Figure 6 and Figure 8 In an embodiment, the cutter 12 is provided with a clearance 121, the clearance 121 penetrates to the end edge of the cutter 12 away from the cutting end, and the connecting shaft 15 is arranged in the clearance 121.

[0080] In this embodiment, the connecting shaft 15 of the pressing member 14 is arranged in the area where the cutter 12 is arranged. This arrangement can reduce the size of the connecting support 11, thereby reducing the volume of the cutter assembly 1 and miniaturizing the cutter assembly 1. In addition, the connecting shaft 15 of the pressing member 14 can be used to limit the cutter 12, so as to prevent the cutter 12 from being inserted too deeply into the mounting groove 111.

[0081] In addition, the clearance 121 arranged on the cutter 12 for the connecting shaft 15 to pass through penetrates to the end edge of the cutter 12 away from the cutting end. In this way, when the cutter 12 is inserted or pulled out, the cutter 12 avoids the connecting shaft 15 through the clearance 121, so that the connecting shaft 15 can be inserted into or pulled out of the clearance 121 from the end opening of the cutter 12 away from the cutting end, thereby eliminating the need to remove the pressing member 14 when the cutter 12 is disassembled, and improving the convenience of disassembling the cutter 12.

Optionally, the pressing member 14 can be rotatably arranged, so that it can roll on the surface of the printing material when cutting the printing material, further reducing the friction between the pressing member 14 and the printing material, and making the cutting process more smooth and stable.

[0084] In an embodiment, the pressing member 14 is rotatably connected to the connecting bracket 11. In this way, when the cutting assembly 1 is applied to cut the printing material, the pressing member 14 can roll on the surface of the printing material, further reducing the friction between the pressing member 14 and the printing material, and making the cutting process more smooth and stable.

[0085] Referring to Figure 8 In an embodiment, the connecting bracket 11 is of an integral structure. In this way, the connecting bracket 11 is simple in structure, and the assembly process can be reduced.

[0086] Referring to Figure 9 and Figure 10 In an embodiment, the connecting bracket 11 comprises at least two sub-structures connected to each other.

[0087] In the present embodiment, the connecting bracket 11 can also be formed by at least two sub-structures connected to each other, for example, the connecting bracket 11 comprises a first part 112 and a second part 113 connected to each other. The two sub-structures connected to each other in the connecting bracket 11 can be inserted, bolted or buckled.

Further, the cutting module 10 and the inkjet module 20 can be integrated into a whole structure to be connected to the same translation assembly 300 and driven by the same translation assembly 300. Since the cutter assembly 1 of the printing module can be retracted, even if the inkjet module 20 and the printing module move together, when inkjet printing is performed without cutting, the cutter assembly 1 only needs to be moved to the retracted position to avoid scratching the printing material during printing. In this way, the number of components in the inkjet printer 1000 can be reduced, and the structure of the inkjet printer 1000 can be simplified.

[0094] The cutter assembly 1 is connected to the driving mechanism 2 and the mounting bracket 3 through the connecting bracket 11.
