A kind of stretching and winding equipment for plastic film

Abstract

The invention relates to a stretching and winding equipment for plastic film, which includes a mounting frame, a tensioning set and a material receiving set. The tensioning set and the material receiving set are sequentially arranged on the mounting frame from left to right. The following problems often exist in the packaging process of the film: a: ​​The existing plastic film often overlaps and is not neat at both ends of the plastic film during the winding and packaging process, so that the edge of the film will be stuck in the subsequent use process The phenomenon occurs, which affects the user experience; b: When the existing plastic film is rolled and packed for a long time, the two sides of the plastic film often shrink due to the middle area, which causes the plastic film to be elongated, which in turn leads to the plastic film itself. Decreased strength reduces product quality.

Description

technical field [0001] The invention relates to the technical field of plastic film packing, in particular to a plastic film stretching and winding device. Background technique [0002] Plastic film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins. It is widely used in the field of article packaging. With the advancement of technology, plastic packaging and plastic packaging products Its share in the market is increasing, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical industry and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging, quick-frozen food packaging, cooking Food packaging, fast food packaging, etc., the above-mentioned product packaging is packaged with plastic film, so the plastic film brings great convenience to people's life, but the existing plastic film is still winding and packing. There are certain de...

Problems solved by technology

[0002] Plastic film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins. It is widely used in the field of article packaging. With the advancement of technology, plastic packaging and plastic packaging products Its share in the market is increasing, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical industry and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging, quick-frozen food packaging, cooking Food packaging, fast food packaging, etc., the above-mentioned product packaging is packaged with plastic film, so the plastic film brings great convenience to people's life, but the existing plastic film is still winding and packing. there are certain deficiencies

[0003] The existing plastic films often have the following problems in the packaging process: a: The existing plastic films often have overlapping and irregular phenomena at both ends of the plastic film during the winding and packaging process, which will cause problems in the subsequent use process. The phenomenon of film edge adhesion occurs, which affects the user experience; b: When the existing plastic film is rolled and packed for a long time, the two sides of the plastic film often shrink due to the middle area, which causes the plastic film to be elongated, which in turn causes The self-strength of the plastic film decreases, reducing product quality
