Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of film unwinding devices, in particular to a PE wrapping film unwinding device. Background Art
[0002] As we all know, PE stretch film is mainly used for product packaging. With the help of the film's super strong wrapping force and retraction, PE stretch film can compactly and firmly bundle the product into a unit. Even in an unfavorable environment, the product will not be loose or separated. It also has no sharp edges and stickiness to avoid damage. When using PE stretch film packaging, the film is unwound through a film unwinding device.
[0003] In real life, when the staff pass the film on the roll through the gap between the two rollers next to it, they need to use their fingers to push the film into the gap between the two rollers. The fingers will be squeezed by the rollers. For some staff members whose fingers suffer from tenosynovitis or rheumatism, the squeezing of the fingers will cause pain. Long time working may increase the severity of the disease. Therefore, the practicality is not very good and there is room for improvement. Utility Model Content
