Description

A plastic film production line

technical field

The utility model belongs to the field of plastic processing, in particular to a plastic film production line.

Background technique

Extrusion production line refers to a production line that can produce plastic pipes, plates, sheets, films and some special-shaped materials. Common types include: pipe extrusion production line, plastic extrusion production line, wood-plastic extrusion production line, composite pipe extrusion production line, granulation extrusion production line, etc. The extruder is the core of the extrusion production line. Common extruders include: parallel twin-screw extruder, SJ series new high-efficiency single-screw extruder, SJZ series conical twin-screw plastic extruder, planetary screw extruder Wait.

Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. The blow molding process began to be used to produce low-density polyethylene vials during World War II. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely used. The volume of the hollow container can reach thousands of liters, and some production has adopted computer control. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc., and the resulting hollow containers are widely used as industrial packaging containers. According to the parison production method, blow molding can be divided into extrusion blow molding and injection blow molding, and the newly developed ones are multi-layer blow molding and stretch blow molding.

The plastic film production adopts an extrusion production line. After the film is extruded from the die, it is blown into a cylindrical shape through the air ring, and then it is wound up to become the final product. In the production process of the film production line at this stage, often due to the After becoming layered, there will be wrinkles and unevenness, which will lead to defective products during winding. This is due to the unreasonable arrangement of the production line at this stage and the planar shape of the flattening rollers.
