AI Technical Summary

Technical Problem

Existing paper tube cutting devices are prone to causing paper tube deformation during the cutting process, which affects quality.

Method used

A high-efficiency paper tube cutting and shaping device was designed. It uses blades on both sides to cut simultaneously, and supports the paper tube with a carrying roller and a pressing roller. Combined with a pushing mechanism and an elastic airbag to fix the paper tube, the stability of the cutting process is ensured.

Benefits of technology

This ensures uniform stress on the paper tube during the cutting process, preventing deformation and guaranteeing cutting stability and quality, while also facilitating post-cutting material handling.

Abstract

The utility model provides an efficient paper tube cutting and shaping device, and belongs to the technical field of paper tube cutting. The efficient paper tube cutting and shaping device comprises a base and a support, the support is fixedly installed on the surface of the base, a cutting mechanism is installed on the surface of the base and used for cutting paper tubes, the cutting mechanism comprises a first sliding base, a cutting machine and a bearing frame, and a pushing mechanism is installed on the surface of the base and used for pushing the paper tubes. The bearing roller is located below the paper tube and abuts against the outer wall of the paper tube. The blade abuts against the outer wall of the paper tube. According to the paper tube cutting device, the cutting mechanism and the pushing mechanism are arranged, the blades on the two sides make contact with the paper tube at the same time, the paper tube is supported by the bearing roller, the paper tube can be evenly stressed, deformation of the paper tube in the cutting process is avoided, and the cutting stability can be guaranteed.
