Problems solved by technology

[0011] However, when cutting paper, the upper knife and the lower knife need to be fully matched together to complete the paper cutting function. There are slight deviations, such as: the upper knife is not rotated in place, the lower knife is not adjusted in place, and the edges of the upper knife and the lower knife are not meshed. And so on will lead to paper cutting failure

Abstract

The invention relates to a paper cutting device. The paper cutting device comprises two paper feeding rollers cooperating with each other, and two paper discharge rollers cooperating with each other;and paper cutting devices are arranged between the paper feeding rollers and the paper discharge rollers. The paper cutting device overcomes the problems of completion of paper cutting through cooperation of the an upper cutter and a lower cutter in paper cutting and unsuccessful paper cutting caused by such conditions as halfway rotation of the upper cutter, halfway adjustment of the lower cutterand halfway engagement of edges of the upper cutter and the lower cutter in the prior art.

Description

technical field [0001] The invention relates to a paper cutting device. Background technique [0002] Paper cutters are used to cut paper rolls into pieces. There are many kinds of paper cutters, such as the gate knife for cutting up and down, the swing knife for intermittent cutting, etc. Although the cutting quality of the paper edge is relatively poor Good, but the paper must be stopped, and the paper can continue to be fed after cutting. The paper feeding speed cannot be fast, and the production efficiency is very low; although the swinging knife can feed the paper continuously, the mechanical impact at the moment of cutting is relatively large, which may easily cause damage to the mechanical equipment. Damage and noise pollution, at the same time, the speed of paper feeding should not be too fast, and the length of paper sheets should not be too short, otherwise there is no time to stop the knife in the middle, resulting in inaccurate length of paper cutting. [0003] ...
