Description

Technical Field

[0002] Bubble film is a product made of high-pressure polyethylene as the main raw material, with the addition of whitening agents, opening agents and other auxiliary materials. It is extruded and blister-formed into bubbles at high temperature. It is a new type of plastic packaging material with light texture, good transparency, non-toxicity and odorlessness. It can prevent moisture, cushion and keep heat for products. It is also called bubble pad. After production is completed, the bubble film needs to be wound. In order to avoid bending and wrinkling after winding, a tensioning device is usually used to stretch and tighten the bubble film.

[0003] After the bubble film is produced, it is necessary to conduct an anti-static test on the surface of the bubble film. However, the existing tensioning device is relatively simple and does not have the detection capability. It cannot be tested when it is wound through the tensioning device. The bubble film needs to be tested for anti-static effects separately, which is more troublesome. In addition, the existing tensioning device can only have a slight stretching and tightening effect on the bubble film, and does not have an adjustment function. Its applicability is poor. For this reason, we propose a bubble film tensioning device with a detection mechanism. Utility Model Content
