Transverse cutting mechanism

Abstract

The invention discloses a transverse cutting mechanism. The transverse cutting mechanism comprises feeding rollers, and is characterized in that the transverse cutting mechanism further comprises a rolling cutter set and a paper core stacking composite component, wherein the rolling cutter set comprises a rolling cutter I and a rolling cutter II which are matched with each other, the rolling cutter I and the rolling cutter II correspondingly comprise rotating shafts and cutters arranged on the rotating shafts; at least two pairs of cutters are arranged on the rotating shafts, and the cutters are uniformly installed on the rotating shafts in the circumferential direction of the cutters, the numbers of the cutters of the rolling cutter I and the rolling cutter II are the same and are arranged in a one-to-one correspondence mode. According to the transverse cutting mechanism, the rolling cutter set is adopted for cutting, the conveying of the paper core plate cannot be influenced during cutting, the paper core plate is enabled to be kept at a high-speed conveying state; and moreover, rolling cutting vibration is small, the stability is high, and the cutting quality is good.

Description

technical field [0001] The invention relates to an improved invention of a cross-cutting mechanism, in particular to a cross-cutting mechanism of a honeycomb paper core of a honeycomb paperboard machine. Background technique [0002] After the multi-layer core paper is compounded into a core board, it is cut into core strips by a cross-cutting mechanism, and the core strips are compounded into a continuous honeycomb paper core. The traditional cross-cutting mechanism adopts horizontal conveying and longitudinal cutting. Please refer to the Chinese patent, the patent number is 201320826424.4, and the invention patent is "A Cross-cutting Device for Honeycomb Paper Core". The paper core board in the above patent is conveyed horizontally. Cutting is realized by the cooperation of the upper knife and the lower knife. There are two problems in the existing cross-cutting device. 1. The upper knife uses a crank-link mechanism to perform repeated cutting actions. High-speed cutting ...

AI Technical Summary

Problems solved by technology

There are two problems in the existing cross-cutting device. 1. The upper knife uses a crank-link mechanism to perform repeated cutting actions. High-speed cutting will cause the knife holder to vibrate, which will affect the stability of the equipment and also affect the cutting quality; 2. The upper knife moves up and down once to realize cutting once. When cutting, the feeding stops, and then feeding is carried out after cutting. It is intermittent feeding, and the efficiency of feeding and cutting is low.
