Description

Technical Field

[0001] The utility model belongs to the technical field of packaging bag production, and in particular relates to a rolling mechanism for PE antistatic packaging bags. Background Art

[0002] PE anti-static packaging bags are a special type of packaging bags. They are made of low-density polyethylene (LDPE) + linear low-density polyethylene (LLDPE) + anti-static masterbatch + color masterbatch + stabilizer, which are mixed and blown into a film and then heat-sealed and cut. This material feels soft and the thickness can be freely adjusted as needed. PE anti-static packaging bags have anti-static functions, which can effectively prevent the accumulation of static charges and protect electronic products from static electricity damage to electronic components due to friction between insulators. Its surface resistivity is low, which is also an important manifestation of its anti-static performance.

[0003] When producing PE anti-static packaging bags, in order to facilitate the subsequent production of packaging bags of corresponding shapes, the packaging bag rolls need to be wound and received. Most of the existing winding mechanisms cannot perform auxiliary compression processing on the packaging bag rolls when winding the packaging bag rolls. After winding, the packaging bag rolls are prone to overall looseness, which affects the overall secondary production of the packaging bags. Therefore, a winding mechanism for PE anti-static packaging bags is needed to assist in solving this problem. Utility Model Content
