Description

Technical Field

[0001] The utility model belongs to the technical field of winding auxiliary of winding film, and in particular relates to a degradable PE winding auxiliary device. Background Art

[0002] Wrap film, also known as stretch film and heat shrink film, was first produced in China with PVC as the base material and DOA as the plasticizer and self-adhesive. Due to environmental issues, high cost (relatively high specific gravity of PE, small unit packaging area), poor stretchability and other reasons, it was gradually eliminated when PE stretch film was produced in China from 1994 to 1995. PE stretch film first used EVA as the self-adhesive material, but it was expensive and smelly. Later, PIB and VLDPE were used as self-adhesive materials, and the base material was mainly LLDPE, including C4, C6, C8 and metallocene PE (MPE).

[0003] The existing authorization number is CN216861904U. The utility model discloses a wrapping film auxiliary device, including a telescopic shaft unit, a first limiting unit, a second limiting unit, a handle unit and a cutting unit. When the wrapping film is packaged, the wrapping film is sleeved with the telescopic shaft unit, and the first limiting unit and the second limiting unit respectively abut against the two ends of the wrapping film, and the wrapping film is relatively rotated with the telescopic shaft unit as the axis through the handle unit; when the packaging is completed, the cutting unit is installed, and the cutting unit is used to cut and separate the wrapping film. Its advantages are that the length can be adjusted by using the telescopic shaft unit, and different specifications of wrapping films can be used; the first limiting unit and the second limiting unit can effectively fix the wrapping film to avoid falling and displacement; the handle unit is convenient for operators to hold and improve the efficiency of the wrapping film; the detachable cutting unit can quickly cut the wrapping film, which is simple and fast, and improves the efficiency of the wrapping film; the structure is simple, easy to use, and low cost. However, the existing device still has some shortcomings. The existing device is insufficient in the length adjustment mechanism, and the device cannot be used when winding films of different widths. Moreover, when the winding is completed, the existing device is a little sticky due to the characteristics of the winding film, and it is not easy to remove. Therefore, it is necessary to provide a degradable PE winding film auxiliary device to solve the above problems. Utility Model Content
