Cutter shaft structure for paper cutter of toilet paper folding machine

Abstract

The invention provides a cutter shaft structure for a paper cutter of a toilet paper folding machine. The cutter shaft structure comprises a cutter shaft body, wherein a surface on which a paper cutter mounting position of the cutter shaft body is attached with the cutter face of the paper cutter is a diagonal plane along a length direction of the cutter shaft body; the diagonal plane inwards forms a curved first minor arc surface; a surface on which the paper cutter mounting position is attached with the cutter back of the paper cutter is a second minor arc surface which makes the cutter back of the paper cutter form an arch back; and the first minor arc surface is intersected with the second minor arc surface at the same time. Due to the scheme, the cutter shaft structure has the advantages of low manufacturing cost of the paper cutter, high paper cutting efficiency, low paper cutting noise, convenience for disassembly and assembly of the paper cutter, short time and the like; and the paper cutter can effectively cut paper and does not have a state that the paper is connected and cannot be cut off due to the time-sharing point contact between the paper cutter and a bar cutter.

Description

technical field [0001] The invention relates to the technical field of paper product processing equipment, in particular to a paper cutter shaft structure of a toilet paper folding machine. Background technique [0002] Traditional toilet paper folding machines generally use the upper and lower opposite and rotating cutter shafts and folding rollers to cooperate with paper cutting to achieve the purpose of cutting paper. Complete cutting, when the lower paper cutter on the folding roller adopts a strip knife, the paper cutter on the knife shaft must also use a strip knife. If the strip knife is not used, there will be continuous paper cutting, but when two Both of them are strip-shaped knives. When touching the tangent, the knife surfaces are in contact at the same time. For multi-layer paper with a certain thickness, there will also be a situation that it cannot be completely cut, so that the next step cannot be completed; therefore, the above-mentioned cutting The paper m...

AI Technical Summary

Problems solved by technology

The specific situation is that the paper cutter is installed vertically on the cutter shaft, and there is an angle between the paper cutter and the strip knife. At the same time, the middle part of the paper cutter and the strip knife is designed as an arc shape. Since the contact surface between the paper cutter and the strip cutter is small at the same time, the above-mentioned beneficial effects can be achieved. However, in order to meet the rigidity requirements during operation, the requirements for the materials used for the paper cutter are particularly high, which greatly improves the efficiency of paper cutting. The manufacturing cost of the knife, otherwise the knife will often break, which will seriously affect the subsequent processing and the quality of the finished product
