Description

Technical Field

[0001] The utility model relates to the technical field of paper cutting devices, in particular to a paper punching machine with adjustable thickness. Background Art

[0002] Currently, with the continuous standardization of information and archive management, relevant information of the current year needs to be bound into volumes for preservation every year. However, for documents with more than 200 pages each that are not suitable for unbinding, such as monthly assessment materials, traditional binding machines cannot meet the binding requirements. They can only be bound using a combination of punching machines and sewing threads, and can only be archived after binding is completed.

[0003] However, existing hole punching machines have limitations on the thickness of the holes they can punch, limiting the maximum perforation depth to 20 pages at a time. Binding with thread is only possible after all the holes are punched, and careful alignment of the holes is required during punching, otherwise the documents will not be neatly bound. Furthermore, punching multiple pages and then binding them is time-consuming and labor-intensive. The key issue hindering archiving is how to efficiently and quickly punch large pages, thereby enabling quick and easy binding.

[0004] A patent with announcement number CN215881807U is disclosed in the prior art. The solution includes a workbench and a machine body. A first through-hole is opened on the outer walls on both sides of the workbench. The inner wall of the first through-hole is movably connected to an adjusting rod. One end of the adjusting rod is located outside the workbench, and an L-shaped connecting rod is welded to the outer wall of the top end of the adjusting rod outside the workbench. A vertically arranged positioning plate is welded to the end of the connecting rod away from the adjusting rod. A second cylinder is fixedly installed on the top of the machine body. The second cylinder is connected downwardly to a second mounting plate, and a paper cutting mechanism is connected below the second mounting plate.

[0008] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content
