A cardboard crease processing device

Abstract

The invention provides a cardboard crease processing device, which relates to the technical field of cardboard creases, a backing board and a paper folding device, a paper sheet is placed on the upper surface of the backing board, and a paper folding device is provided on the surface of the paper sheet, and the paper folding device includes a slider, a sliding The lower surface of the block is slidably connected with the backing plate, the inner wall of the table-shaped groove of the slider is threadedly connected with a spring pad, the end of the spring pad far away from the slider is fixedly connected with the rotating block, and the end of the rotating rod away from the rotating block is rotatably connected with a pressure plate, and The lower surface of the pressing plate is in contact with the paper, the side of the pressing plate close to the paper is fixedly connected with a first spring, and the end of the first spring away from the pressing plate is fixedly connected with a supporting plate, and the upper surface of the supporting plate is in contact with the paper. The present invention solves the problem that the traditional method is to bend the cardboard manually, but because the thickness of the cardboard is relatively large, it will take time and effort to bend the cardboard. When the bending force is too large, the cardboard will break, which not only causes waste of cardboard And it also greatly reduces the problem of work efficiency.

Description

technical field [0001] The invention relates to the technical field of cardboard creases, in particular to a cardboard crease processing device. Background technique [0002] Cardboard, also known as board paper, is a thick paper sheet made of various pulps and interwoven fibers. The difference between cardboard and paper is usually distinguished by quantitative and thickness, and the functions of cardboard and paper are also different. [0003] When it is necessary to bend the cardboard to obtain creases, the traditional method is to bend the cardboard artificially. However, due to the large thickness of the cardboard, it will take time and effort to bend the cardboard. When the bending force is too large, the cardboard will break. , Not only caused the waste of cardboard but also greatly reduced work efficiency. Contents of the invention [0004] The object of the present invention is to propose a cardboard crease processing device in order to solve the shortcomings in ...
