Paper-based degradable plastic bag molding and processing system and molding and processing technology

Abstract

The invention relates to a paper-based degradable plastic bag molding and processing system and molding and processing technology. The paper-based degradable plastic bag molding and processing systemcomprises a bottom plate, a stretching device, a cutting device and an unwinding device, wherein the unwinding device is arranged at the left end of the bottom plate, the cutting device is arranged atthe right end of the unwinding device, and the stretching device is arranged at the lower end of the cutting device. The paper-based degradable plastic bag molding and processing system and the molding and processing technology can solve the following problems existing in the cutting of an existing rolled film that when the traditional rolled film is cut, when the film needs to be cut by hand with a cutting knife, due to the large factor of human error, the film is easy to shrink under fore during cutting, the cutting quality cannot ensured, the cutting efficiency is low, and the cut film isdifficult to reach the required size; when the traditional film cutting machine cuts the film, the film can only be cut on one side and cannot be cut at equal interval at the same time; moreover, as the film is soft, the film is often cut unevenly, and thus the appearance is affected and raw materials are wasted.

Description

technical field [0001] The invention relates to the technical field of plastic bag manufacturing and processing, in particular to a paper-based degradable plastic bag forming and processing system and a forming process. Background technique [0002] Plastic bags bring convenience to our lives, but the recycling value of plastic bags is low, causing white pollution during use, and there are also potential hazards. The plastic structure is stable and not easily degraded by natural microorganisms. The environment will not be separated for a long time, which means that if the waste plastic waste cannot be effectively recycled, it will become a permanent pollutant in the environment and accumulate continuously, which will cause great harm to the environment. With the continuous improvement of people's environmental awareness Therefore, it is the general trend to replace ordinary plastic bags with environmentally friendly plastic bags.

Problems solved by technology

[0002] Plastic bags bring convenience to our lives, but the recycling value of plastic bags is low, causing white pollution during use, and there are also potential hazards. The plastic structure is stable and not easily degraded by natural microorganisms. The environment will not be separated for a long time, which means that if the waste plastic waste cannot be effectively recycled, it will become a permanent pollutant in the environment and accumulate continuously, which will cause great harm to the environment. With the continuous improvement of people's environmental awareness Therefore, it is the general trend to replace ordinary plastic bags with environmentally friendly plastic bags. When producing environmentally friendly plastic bags, it is necessary to cut the roll film

[0003] However, the following problems exist in the cutting of roll film at present. First, when cutting the traditional roll film, it is necessary to manually hold the scissors to cut the film. Due to the large factor of human error, the film is easily subjected to force during cutting. Shrinkage, cutting quality cannot be guaranteed, labor intensity is high, cutting efficiency is low, the film cut out is difficult to reach the required size, and fingers may be accidentally cut when using a cutting knife manually; When cutting, the film can only be cut on one side, and the film cannot be cut at equal intervals at the same time, and because the film is soft, the film is often cut unevenly, which affects the appearance and wastes raw materials. The effect is good, greatly improving the efficiency and cutting effect of film cutting
