Description

Technical Field

[0001] The present invention relates to the technical field of blow molding, and specifically relates to a continuous blow molding device for high-transparency PE films. Background Art

[0002] Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. With the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely used. The volume of hollow containers can reach several thousand liters, and some productions have adopted computer control. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc.

[0003] At the present stage, when producing high-transparency PE films, a blow molding device is required for forming processing. In the existing blow molding device, the feeding is prone to interruption during forming, reducing the processing efficiency.
