A second guide rod is assembled inside the right adjustment box, and a sliding sleeve is connected to the outside of the second guide rod.

[0011] As a further technical solution of this utility model, the threaded block and the second threaded rod form a threaded connection, and the second guide rod and the sliding sleeve form a sliding connection.

[0012] As a further technical solution of this utility model, the top of the regulating box is provided with a guide groove, and the top of the sliding sleeve and the threaded block are fixed with guide blocks, and the guide blocks are connected and fixed to the bottom of the vertical rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this paper production cutting device not only improves the clamping capacity, but also improves the blade replacement and adjustment capabilities of the cutting device.

[0014] (1) The workbench is mounted in the middle of the top of the base plate, and upright plates are mounted on both sides of the top of the workbench. The top plate is fixed in the top position of the upright plates. Therefore, after the second telescopic rod works, the height position of the pressure plate can be adjusted. During this process, the slider forms a sliding guide in the slide groove. Therefore, after the paper is placed in the upper position of the workbench, when the pressure plate moves, it relies on the rubber pad to contact the paper to form a pressing operation. This improves the overall pressing capacity during the working process.

[0015] (2) By assembling the connecting seat at the bottom of the mounting plate, a mounting hole is opened in the top of the cutting blade, so the cutting blade can be inserted into the interior of the connecting seat. After inserting the locking pin in the mounting hole, the locking nut and the locking pin are used to complete the thread locking work. Therefore, it is convenient to connect and assemble the cutting blade during the working process.

[0016] (3) After the first motor works, it can drive the first threaded rod to rotate. At this time, the first threaded rod cooperates with the movable block to form a lateral movement. This process is guided by the first guide rod. After the first telescopic rod works, it can push the height position of the cutting blade to adjust. At the same time, after the second motor works, it can drive the second threaded rod to rotate. At this time, the second threaded rod and the threaded block cooperate to form a back-and-forth movement. This process is guided by the second guide rod and the sliding sleeve. This achieves the purpose of back-and-forth adjustment. Therefore, the overall adjustment capability is improved in the working process. Attached Figure Description
