Description

Technical Field

[0001] The utility model relates to the technical field of blow molding machines, in particular to a PE film blow molding machine. Background Art

[0002] Packaging bags are a kind of plastic film product. They are mainly made by heating and melting the plastic raw materials into a molten state through an injection molding machine, and then inputting the plastic raw materials into the die of a film blowing machine under high pressure. Generally, the bottom of the die will be heated to keep the material in a molten state. Then, the molten material continues to move upward in the gap in the die, and the accumulated molten material gradually reduces its thickness through the gap in the die until a film of standard thickness is formed. In this process, the air ring set up on the die will also gradually cool the molten material, so that the material is in a solid film state when it is output from the die. Then, the film is rolled up through the subsequent winding device and then processed.

[0003] In the prior art, after the winding device is wound up, since the PE film has some wrinkles on its surface during production, when there are many wrinkles, the wound up PE film will become fluffy and not fit the surface of the winding device, thereby affecting the quality of the produced PE film and affecting its use.
