Description

Technical Field

[0001] The utility model relates to the technical field of film winding, in particular to a winding device used for plastic film production. Background Art

[0002] The plastic film winding device is an important device in the plastic production process, which is used to complete the winding operation of the plastic film after it is formed.

[0003] Publication number: CN 212402834 U proposes a winding device for plastic film production. In this case, an annular plate is sleeved on the outer wall of the drum, and then an electric telescopic rod fixed on one side pushes the pushing block. The pushing block at the end of the electric telescopic rod is limited by the drum, so that the cylinder end drives the second support plate to move to the right, that is, the annular plate is driven to move to the right by the fixed rod, so as to adjust the width of the drum, so as to make it suitable for winding films of different sizes. However, during the winding process, the surface of the film will dry and carry some static electricity, which is easy to absorb a lot of impurities and dust, thereby affecting the winding quality of the film. In addition, during the winding process, the film is prone to wrinkles and looseness, which is not conducive to the winding operation. Therefore, it is necessary to propose a winding device for plastic film production to solve the above problems. Utility Model Content
