Description

Technical Field

[0001] The utility model relates to the technical field of paper cutters, in particular to a continuous cutting paper cutter. Background Art

[0002] Paper machine is a kind of cutting machine and is widely used in paper processing. Since printing, packaging, book binding and other production processes require paper cutters for cutting from cutting to printed products and cutting of rough copies after binding, there are many types of paper cutters on the market, and hydraulic paper cutters can cut texts on different paper types smoothly, making them very suitable for processing large quantities of documents.

[0003] For example, a precision cutting paper cutter disclosed in publication number CN220638052U drives the cutting knife and the connecting rod to cut downwards through a first electric push rod, and then the connecting rod drives the pressing paper board to press downwards, thereby pressing and fixing the paper during the paper cutting process, through the coordinated arrangement of the receiving trough and the receiving box.

[0004] However, when the cutting structure is in use, it can only press the paper underneath it during the paper cutting process. However, the paper is prone to deviation when it moves through the conveyor belt. At this time, even if the paper pressing plate is pressed down, the end of the paper cannot be prevented from tilting. In addition, the device cannot move the cut paper away after cutting, but needs to be taken away manually, which reduces the practicality of the device. In view of this, we propose a continuous cutting paper cutter. Utility Model Content

[0016] Beneficial effects:

[0017] 1. The continuous cutting paper cutter is provided with a positioning structure so as to facilitate the centering and fixing of the paper. The user drives the paper to move through the transmission structure. At this time, the paper will move on the surface of the operating table and contact the positioning frame. The user can adjust the position of the positioning frame to position the length of the paper cutting. At the same time, when the paper moves, it will squeeze and move the contact plate. At this time, the connecting block drives the sliding rod to move, and then drives the pressing frame to move downward to squeeze and support the end of the paper. Then, the paper can be pushed manually to align the paper with the positioning plate to avoid offset, and then the cutting work can be carried out.
