Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of plastic bag processing, and particularly relates to a static electricity eliminating device with adjustable guide rollers. Background Art
[0002] In the production of plastic bags, friction, production environment and other factors will cause plastic bags to carry static electricity. Static electricity will make it difficult for plastic bags to be fully unfolded in subsequent production, causing certain inconveniences for spraying and other processes, and will increase the defective rate of plastic bags in subsequent process production. Therefore, it is necessary to eliminate static electricity from plastic bags to facilitate production and processing and improve product quality. However, most of the plastic bag static electricity elimination devices used in actual production cannot adjust the guide rollers used for static electricity elimination according to actual production. Most of the static electricity elimination guide rollers are set with two groups, and the plastic bag is passed through the two groups of guide rollers to eliminate static electricity on the outer surface of the plastic shell. However, the thickness of plastic bags produced in actual production is different, which results in the static electricity elimination device that cannot adjust the guide rollers having the same gap for plastic bags with different processing thicknesses. Plastic bags with inconsistent thicknesses have different static electricity elimination effects. For example, a wider gap may make it impossible to completely eliminate static electricity from thinner plastic bags, and the static electricity elimination effect cannot be achieved.
[0003] Secondly, if static electricity is eliminated on thicker plastic bags when the gap is narrow, the plastic bags may be over-extruded, causing some tearing of the plastic bags when passing through the two sets of guide rollers, which will have a certain impact on the quality of the plastic bags.
[0004] In summary, there are certain problems in the use of a plastic bag static elimination device whose guide roller cannot be adjusted, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
