AI Technical Summary

Technical Problem

When the existing PE heat shrink film rolling device replaces the roll, the rolling device will directly impact the driving wheel when it falls, resulting in a large impact force. After long-term use, the driving wheel loses severely and lacks buffering devices, which makes it poor in practicality.

Method used

A PE heat shrink film rolling device is designed. By setting a spring and a driven wheel on the bracket, the fixed block compresses the spring when it slides on the slide chute, slows down the falling speed, cushions the impact force, and reduces the impact force on the driving wheel.

Benefits of technology

It effectively reduces the loss of the driving wheel, improves the practicality of the device, and extends the service life of the driving wheel.

Description

Technical Field

[0001] The utility model relates to the technical field of film material processing, in particular to a PE heat shrink film rolling device. Background Art

[0002] As we all know, PE heat shrink film is an industrial film product with high tensile strength, large elongation, good self-adhesion, high transparency and other physical properties. It can be widely used in the centralized packaging of various goods. After the processing of PE heat shrink film is completed, the PE heat shrink film needs to be rolled into a PE heat shrink film roll by the film rolling equipment.

[0003] In real life, the roller of the existing PE heat shrink film rolling device is generally movably arranged, and two lifting brackets are arranged on the connecting rod of the device. When the roller is replaced, the new roller automatically rolls to the middle of the lifting bracket. After winding the PE heat shrink film, the roller rolls down from the rotating lifting bracket for quick replacement. When the roller rolls down to the bottom of the lifting bracket, it will directly hit the driving wheel at the bottom, which will produce a large impact force on the driving wheel. After long-term use, the driving wheel will produce certain wear and tear and require regular maintenance. The device does not have a device to buffer the impact force of the roller falling, so the practicality is not very good and there is still room for improvement. Utility Model Content

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a PE heat shrink film rolling device, which has the following

[0015] Beneficial effects:

[0016] In the PE heat shrink film rolling device, when the fixed block of the rolling roller slides down the upper part of the slide groove of the bracket, it will first press on the driven wheel, drive the driven wheel to rotate downward, compress several springs and contract. At this time, the spring will generate a reaction force on the fixed block, which can buffer most of the impact force and slow down the falling speed of the fixed block. At this time, the speed at which the fixed block rolls onto the driving wheel becomes slower, reducing the impact force on the driving wheel, thereby reducing the loss of the driving wheel and further improving the practicality to a certain extent.
