[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will combine the accompanying drawings of the embodiments of the present utility model Figures 1 - 3 to clearly and completely describe the technical solutions of the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by the present utility model.

[0026] As Figures 1 - 3 shown: It includes a conveying mechanism 100. The conveying mechanism 100 is a step conveyor. The conveying mechanism 100 includes a bracket 101 and a conveyor belt 102 provided on the bracket 101. The cardboard is placed on the conveyor belt 102. The conveyor belt 102 can rotate on the bracket 101 to drive the cardboard to move. A printing mechanism 200 is also correspondingly provided on the bracket 101 for the conveyor belt 102. The bracket 101 provides support for the printing mechanism 200. The printing mechanism 200 includes a printing roller, that is, when the printing mechanism 200 works, the printing roller can print on the paper. A gantry 300 is also provided on the bracket 101. The gantry 300 is arranged on the side of the printing mechanism 200 and close to the printing mechanism 200. A plurality of movable rods 301 are hinged on the gantry 300. The movable rods 301 can rotate on the gantry 300. In this embodiment, the movable rods 301 are provided as two and arranged at the middle position of the gantry 300. And a torsion spring 303 is also correspondingly provided on the gantry 300 for the movable rods 301. One end of the torsion spring 303 is connected to the movable rod 301, so that the torsion spring 303 can indirectly abut the end of the movable rod 301 away from the gantry 300 on the conveyor belt 102. And when the position of the movable rod 301 changes, the movable rod 301 can automatically reset through the torsion spring 303. A pressure wheel 302 is also provided at the end of the movable rod 301 away from the gantry 300. Thus, when the paper passes under the gantry 300, the pressure wheel 302 can abut on the upper surface of the paper, so that it can prevent one end of the paper from warping during the conveying process;

[0027] On both sides of the gantry 300, there are also vertically penetrating perforations 400. A slider 401 is slidably arranged in the perforation 400. A guide rod 402 is vertically arranged at the bottom of the slider 401. A guide plate 403 is arranged at the end of the guide rod 402. The guide plate 403 is of an L-shaped structure. The two guide plates 403 are symmetrically arranged, and the end with a shorter distance between the two guide plates 403 is arranged close to the printing mechanism 200. Thus, when the cardboard is on the conveyor belt 102, it will first move to the end with a longer distance between the two guide plates 403, and then, driven by the frictional force when the conveyor belt 102 rotates, the cardboard can be in contact with the inclined surface of the guide plate 403 and move to the end with a shorter distance between the two guide plates 403. The two guide plates 403 complete the adjustment of the paper position.

[0028] When producing a sterile packaging box, it is necessary to first place the raw material paper of the packaging box on the conveyor belt 102 of the conveying mechanism 100, and then the operation of the conveying mechanism 100 can make the conveyor belt 102 rotate on the bracket 101. The conveyor belt 102 can transport the paper between the two guide plates 403. The two guide plates 403 can adjust the position of the paper. And when the paper moves below the gantry 300, the pressing wheel 302 at the end of the movable rod 301 can be in contact with the upper surface of the paper. The pressing wheel 302 can prevent the paper from warping during the conveyance on the conveyor belt 102. When the paper passes below the printing mechanism 200 on the conveyor belt 102, the printing roller on the printing mechanism 200 can print the paper.

[0029] As Figure 2 、 3 shown,

[0030] The cross-section of the slider 401 is of an I-shaped structure, that is, when the slider 401 slides back and forth in the perforation 400, it will not fall off from the perforation 400. That is, when the sliding slider 401 moves in the perforation 400, it can drive the guide plate 403 to move through the guide rod 402, so that the position of the guide plate 403 can be changed, and then the paper with different widths can be limited.

[0031] As Figure 2 、 3 shown,

[0032] A threaded hole 404 is penetrated through the slider 401. A bolt is provided corresponding to the threaded hole 404. When the guide plate 403 moves to the specified position, the bolt is inserted into the threaded hole 404 until the end of the bolt abuts against the top of the gantry 300, so that the fixing effect on the slider 401 can be achieved, and then the positions of the two guide plates 403 can be fixed.

[0033] As Figure 2 shown,

[0034] A connecting piece 500 is provided at the bottom of the gantry 300 , and the connecting piece 500 is fixed to the bracket 101 by bolts. The connecting piece 500 can be fixed to the bracket 101 or removed from the bracket 101 by bolts, thereby facilitating the installation or disassembly of the gantry 300 .

[0035] like Figure 1 , 2 As shown,

[0036] The conveyor belt 102 is also provided with a plurality of friction strips 103, the spacing between each two adjacent friction strips 103 is consistent, and the cross-section of the friction strip 103 is a semicircular structure, that is, the friction strip 103 can move against the cardboard, thereby preventing the end of the paper from slipping on the conveyor belt 102 after it hits the pressure wheel 302.

[0037] As shown in 1 and 2,

[0038] A connecting rod 501 is also provided on the side of the gantry 300, and a support rod 502 is provided at the end of the connecting rod 501. The support rod 502 is horizontally arranged at the end of the connecting rod 501, and the connecting rod 501 provides support for the support rod 502. A brush layer 503 is provided at the bottom of the support rod 502. The brush layer 503 can prevent the paper from entering between the two guide plates 403 in an inclined state, thereby preventing the paper from being printed after being flipped 90 degrees.

[0039] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0040] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
