Description

TECHNICAL FIELD

[0002] Plastic bags are bags made of thin plastic film, which are used to contain other objects and are essential in people's daily life. Plastic bags are widely used because of their low cost, extremely light weight, large capacity and easy storage, but they have the disadvantages of long degradation period and difficult disposal. Therefore, new degradable environment-friendly plastic bags are produced. Environment-friendly plastic bags are a short name for all kinds of biodegradable plastic bags. Environment-friendly plastic bags are one of the core products of the environmental protection industry and belong to the core track of the environmental protection material industry. In the production and manufacturing of environment-friendly plastic bags, the use of bag making machines is essential. A bag making machine is a machine for making various plastic packaging bags or packaging bags made of other materials. Its processing range includes packaging bags made of various sizes, thicknesses and specifications of plastic or other materials. Generally, plastic packaging bags are the main products.

[0003] In the processing process, the bag opening of the environment-friendly plastic bag needs to be cut to separate it into a single environment-friendly plastic bag. However, the existing cutting equipment lacks a guiding structure for the conveying process of the plastic bag, which causes the plastic bag to easily wrinkle during the conveying process, thereby causing irregular cutting. At the same time, the friction between the plastic bag and the conveying roller generates static electricity, which easily causes the plastic bag to be adsorbed on the guide roller due to static electricity and on the cutting blade after cutting, affecting the normal progress of the cutting work. In addition, cutting and heat sealing are two steps in the traditional equipment, which increases the complexity of the equipment and reduces the work efficiency.
