Description

Technical Field

[0001] The utility model belongs to the technical field of plastic film roll unloading, in particular to an improved automatic unloading device for plastic film rolls. Background Art

[0002] The inconvenience of unloading the plastic film roll means that during the production and processing, due to some reasons, the plastic film roll cannot be smoothly unloaded from the roll, which brings difficulties and inconvenience to production and processing. The main disadvantages of the inconvenience of unloading the plastic film roll are as follows:

[0003] Low production efficiency: Since plastic film rolls are inconvenient to unload, they need to be unloaded manually, which is inefficient. This not only increases production time and costs, but also affects the production efficiency and capacity of the entire production line.

[0004] Unstable unloading quality: Manual unloading is often limited by operating skills and experience, and the unloading quality is unstable, which can easily cause problems such as coil deformation, knotting, and breakage, reducing the use value and quality of the coil.

[0005] There are great safety hazards: During the manual unloading process, due to the need for manual operation, there are safety hazards, such as fingers being caught by the coil, the coil suddenly falling off, etc., which can easily cause injuries and accidents.

[0006] More waste: During the manual unloading process, due to the limitations of operating skills and experience, it is easy to cause waste of coils, resulting in waste of production costs and resources.

Therefore, in the production and processing process, appropriate measures should be taken to improve the automation and quality of unloading to improve production efficiency and reduce costs. Therefore, an improved automatic unloading device for plastic film rolls is urgently needed. Utility Model Content
