Description

Technical Field

[0001] The utility model belongs to the technical field of low-pressure plastic bag processing, in particular to an anti-deviating cutting device for low-pressure plastic bag processing. Background Art

[0002] Plastic bags refer to bags made of plastic as the main raw material, which are often used to hold other items. Low-pressure plastic bags belong to the category of plastic bags. Low-pressure plastic bags refer to plastic bags produced using low-density polyethylene as raw material. In the production process of low-pressure plastic bags, workers need to operate the cutting device to cut the low-pressure plastic bags. The cutting device for low-pressure plastic bag processing is mainly composed of a workbench, a unwinding roller, a winding roller, a drive motor and a cutting machine.

[0003] After searching, a patent document with patent announcement number CN213006803U discloses a bag cutting device for plastic bag production, which belongs to the technical field of plastic bag cutting equipment, including a workbench, a first mounting seat and a second mounting seat are respectively fixed on both sides of the top of the workbench, a first motor is installed on the outer surface of the first mounting seat, and a guide roller is connected to the output end of the first motor through a first rotating shaft sleeve; by providing a slag drop hole, a collection box, a slider, a slide groove, and a pull rod, when the cutting knife cuts the plastic bag, the generated debris will fall into the slag drop hole through the cutting hole, and fall into the collection box through the slag drop hole, so that the collection box can collect the debris, which is convenient for the user to clean the debris later, and when the debris in the collection box needs to be cleaned, the user pulls the pull rod, the pull rod moves to drive the collection box to move, the collection box moves to make the slider slide in the slide groove, and when the slider slides out of the slide groove, the user can clean the debris in the collection box.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. The existing plastic bag cutting device for production, during use, uses a pressing roller to press the moving plastic bag against the workbench, thereby preventing the plastic bag from shifting during the movement, thereby facilitating the subsequent cutting and processing of the plastic bag. However, the plastic bag body will directly contact and rub against the workbench during the movement, thereby causing wear of the plastic bag, thereby reducing the quality of the plastic bag;

[0006] 2. In the use of the existing plastic bag cutting device, the waste generated in the plastic bag cutting process is collected by the set collection box, thereby effectively preventing the plastic bag waste from falling everywhere and effectively reducing the cleaning workload of the subsequent staff. However, when cleaning the plastic bag waste inside the collection box, the entire collection box needs to be disassembled and assembled, which will increase the workload of the staff and bring inconvenience to the cleaning of the plastic bag waste.
