Paper grooving cutter

Abstract

The invention discloses a paper grooving cutter. The paper grooving cutter comprises an upper cutter holder, a lower cutter holder, an upper cutter and a lower cutter, wherein the upper cutter and thelower cutter are rotatably arranged on the upper cutter holder and the lower cutter holder respectively, the upper cutter holder and the lower cutter holder are distributed up and down, so that a first grooving space for allowing paper to pass therethrough for grooving is formed between the upper cutter and the lower cutter, the upper cutter and the lower cutter are of roller structures, two cutting edges are arranged on the wheel edge of the lower cutter, the two cutting edges are arranged at intervals to form a second grooving space between the two cutting edges, and the wheel edge of the upper cutter is matched with the second grooving space to groove paper. According to the paper grooving cutter, through the arrangement of the upper cutter and the lower cutter, a cutting groove can beeffectively formed in the paper, thus, the situation that the position of the cut paper needs to be adjusted so as to form a bending space is avoided, and the structure of a film laminating machine is effectively simplified.

Description

technical field [0001] The invention relates to a cutting knife, more specifically to a paper slotting knife. Background technique [0002] In order to extend the shelf life and make the cover look brighter and more beautiful, the paper used as the cover generally chooses to cover the cover paper with a layer of film to protect the cover paper and increase the beauty of the cover paper. [0003] However, the existing cover of a book requires bending of the cover paper to achieve the effect that the cover paper can be turned over because it needs to be turned over. However, if the coated paper is bent, it will It is easy to cause a gap between the film and the paper, which will cause white marks on the cover, which will affect the appearance and the air will enter the gap to reduce the shelf life of the paper. Therefore, in the prior art, the part of the cover paper that needs to be bent is cut off and only left The method of lowering the film is used to solve the above prob...

AI Technical Summary

Problems solved by technology

[0003] And existing as the cover of book, because need to carry out page-turning operation, therefore just need to bend cover paper, to achieve the effect that cover paper can be turned page, but after the paper after lamination is bent, will It is easy to cause a gap between the film and the paper, which will cause white marks on the cover, which will affect the appearance and the air will enter the gap to reduce the shelf life of the paper. Therefore, in the prior art, the part of the cover paper that needs to be bent is cut off and only left The method of lowering the film is used to solve the above problems. However, the laminating machines in the prior art can only realize the laminating effect. If a cutter is directly installed to cut the paper, it will cause edge trimming between the two papers in the subsequent cutting. The problem of unevenness, at the same time, the distance between the two sheets of paper needs to be adjusted through the subsequent distance adjustment device after cutting, so it is necessary to install the distance adjustment device, which makes the structure of the laminating machine more complicated
