Description

Technical Field

[0001] This utility model relates to the field of bubble film processing technology, and more specifically, to a wear-resistant bubble film processing, transmission and tensioning device. Background Technology

[0002] Bubble wrap is a product made primarily of high-pressure polyethylene, with added whitening agents, opening agents, and other auxiliary materials, extruded and vacuum-formed into bubbles at approximately 230 degrees Celsius. It is a lightweight, transparent, non-toxic, and odorless new type of plastic packaging material that provides moisture protection, cushioning, and insulation for products. It is also called bubble pad.

[0003] In the production and processing of bubble wrap, the finished bubble wrap needs to be transported and wound up. To improve the winding effect, tensioning equipment is required to tension the bubble wrap. However, the bubble wrap processing and conveying tensioning equipment currently on the market still has some shortcomings. During the conveying and winding process, the linear speed of the winding roller and the unwinding roller changes as the conveying progresses, causing the internal tension of the bubble wrap to change during the tensioning process. However, most of the bubble wrap processing and conveying tensioning equipment on the market has a simple structure and is not convenient for automatically adjusting the tension of the bubble wrap during the conveying process, which makes the bubble wrap prone to stretching and deformation during transport. Therefore, we propose a wear-resistant bubble wrap processing and conveying tensioning equipment to solve the above-mentioned problems. Utility Model Content
