a cutting device

Abstract

A cutting device comprises a fixed knife and a movable knife. Each of the fixed knife and the movable knife is divided into a cutting portion and a connecting portion which are connected to be a whole, the cutting portion of each of the fixed knife and the movable knife is square steel, and the movable knife can realize linear up-down moving and rotating along the connecting portion of the fixed knife. Knife bodies of the cutting device are less prone to deformation and good in cutting effect, and the cutting device is convenient to mount, so that mounting time is reduced greatly. During cutting, the movable knife does not need to be lifted highly, so that cutting efficiency and cutting strength are improved; both thin plastic woven cloth and thick plastic woven cloth can be cut, so that the cutting device is wide in application range.

Description

technical field [0001] The invention relates to the technical field of woven bag production equipment, in particular to a cutting device for quickly cutting woven bags. Background technique [0002] Plastic woven bags are widely used, especially for the packaging of chemical fertilizers, chemical raw materials, cement, and grain. Therefore, the production volume of plastic woven bags is very large, and the equipment for producing plastic woven bags has also changed from traditional manual production to automatic assembly line production, and the production efficiency has also been greatly improved. [0003] The production process of plastic woven bags usually includes cutting and sewing of woven cloth, and one of the most important process steps that directly affects production efficiency is the cutting of woven cloth. The cutting of the existing woven cloth is completed by the cooperation of the fixed cutting blade and the movable cutting blade. Wherein the fixed cutting ...

AI Technical Summary

Problems solved by technology

The installation process is complicated, and the position accuracy of the blade installation is high, and the installation efficiency is low

[0005] Second, during the long-term cutting process of the woven bag, the screw on the blade will loosen, and the blade at the position corresponding to the screw will be lifted, causing the blade to deform and affecting the cutting quality of the woven bag

[0007] Fourth, in the traditional cutting method, there are two ways of moving the blade, one is that the fixed blade does not move, one end of the movable blade is hinged to one end of the fixed blade, and the other end of the movable blade is raised and rotated around the hinged end of the fixed blade In this cutting method, the raised end of the movable blade needs to be raised to a very high height, which affects the cutting efficiency and takes up a large space; the second is that the fixed blade does not move, and the movable blade is inclined, and there is a certain angle between the fixed blade and the fixed blade. The movable blade moves up and down as a whole to complete the cutting action. This cutting method has a small cutting force and is suitable for cutting relatively thin woven bag cloth.
