Cutter roller set for domestic paper processor

Abstract

The invention relates to a cutter roller set for a domestic paper processor, comprising at least one fixed cutter roller and at least one bottom cutter roller. At least one fixed cutter set is designed on the fixed cutter roller; at least one bottom cutter is designed on the bottom cutter roller; and the fixed cutter of the fixed cutter set is a blade body with an arc-shaped cutter point. As the fixed cutter of the fixed cutter set is designed into a blade body structure with an arc-shaped blade, the bottom cutter and the fixed cutter are matched in an arc shape for cutting during rotation of the bottom cutter roller so that the motion trail formed at the cutting place is an even and continuous arc-shaped intersection line when the fixed cutter and the bottom cutter of the cutter roller set are crossed in an inclined way to cut original paper. Therefore, the invention ensures even stress on the fixed cutter and little abrasion of the fixed cutter and the bottom cutter, effectively prolongs the service life of the fixed cutter and the bottom cutter, reduces the cost, greatly improves the cutting effect and efficiency of the fixed cutter and the bottom cutter, improves the production efficiency and has the advantages of simple structure, easy production, strong practicability, and the like.

Description

technical field [0001] The invention relates to the technical field of household paper processing, in particular to a cutter roll set for a pump-type facial tissue machine and a paper towel machine. Background technique [0002] The cutter roll set (such as Figure 4 shown), generally consists of a fixed knife roll 4 and a bottom knife roll 2. There are generally three bed knives 1 distributed at intervals on the bed knife roll 2, and a straight knife-edge blade body (such as Figure 5 Shown, claim straight fixed knife 5) here. Since the straight fixed knife 5 on the fixed knife roller 4 is a blade body with a straight edge, in the shearing process, since the bottom knife follows the rotation of the bottom knife roller to form an arc-shaped trajectory, the fixed knife is a constant straight line However, during the shearing process, the shearing force of the fixed knife in the middle position is large, and the shearing force on both sides is small, thus causing the problem...

AI Technical Summary

Problems solved by technology

Since the straight fixed knife 5 on the fixed knife roller 4 is a blade body with a straight edge, in the shearing process, since the bottom knife follows the rotation of the bottom knife roller to form an arc-shaped trajectory, the fixed knife is a constant straight line However, during the shearing process, the shearing force at the middle position of the fixed knife is large, and the shearing force on both sides is small, resulting in the problem of uneven shearing force on the straight fixed knife 5 and the bottom knife 1 as a whole, so that The fixed knife bends and deforms once during each cutting process, which not only affects the cutting effect of the sheared paper, but also increases the wear of the straight fixed knife 5 and the bottom knife 1, and the shearing noise is large. Knife 5 is easy to wear and crack, reducing the service life of bottom knife 1 and straight fixed knife 5 and reducing production efficiency
