Description

Technical Field

[0001] The utility model relates to the technical field of PE plastic bag production, in particular to a cutting device with a protective structure. Background Art

[0002] PE plastic bags, as a storage product, have brought many conveniences to our lives and have become an indispensable product. PE plastic bags often require a lot of equipment in the process of processing and manufacturing, and cutting devices are one of them. In the production process of PE plastic bags, two layers of single-layer films need to be rewound together to form a double-layer film, and then the rewound double-layer film is cut into small pieces of plastic sheets using a cutting device. The same edges are hot-pressed later to become ordinary plastic bags.

[0003] A cutting device for producing PE plastic bags disclosed in the Chinese utility model patent application disclosure CN218398248U removes dust from PE plastic film through a dust removal cloth, thereby preventing dust particles from falling on the cut on the surface of the plastic film. The obstruction of dust particles causes the cut of the plastic film to be uneven, resulting in irregular shapes of the cut plastic bags, thereby improving the efficiency and quality of workshop production. However, the existing cutting device lacks a collecting device and a protective device, and the cut products need to be manually collected and stacked. Close contact with the cutting device is prone to dangerous events such as injuries, which reduces the safety of the device and cannot meet people's usage needs. It is urgently needed to be developed. Utility Model Content
