Biodegradable plastic bags are a type of plastic bag developed in response to national environmental protection requirements. They can be decomposed by microorganisms in the natural environment. During the production of biodegradable plastic bags, because the semi-finished product is a continuous strip, it needs to be cut at specific locations using a shearing device. Existing technology publication number CN219096089U discloses a shearing device for processing biodegradable plastic bags, including a worktable. Electric telescopic rods are fixedly installed on the top of the worktable near both sides, and a top plate is fixedly installed at the top of the electric telescopic rods. A collection box is located at the bottom of the worktable. The moving mechanism includes a mounting box, with a lead screw running through the right side of the mounting box near the top. A rotary valve is fixedly installed at the right end of the lead screw, and the left end of the lead screw is rotatably connected to the left side of the inner cavity of the mounting box. Threaded sleeves are threadedly connected to the outer edge of the lead screw near both sides, and load-bearing plates are fixedly installed at the top of each threaded sleeve. However, during use, the plastic bags need to be manually placed on top of the load-bearing plates, resulting in poor work continuity and affecting processing efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a cutting device for processing food-grade environmentally friendly biodegradable plastic bags, which ensures cutting accuracy, improves work continuity, and increases processing efficiency.

[0004] This utility model discloses a cutting device for processing food-grade environmentally friendly biodegradable plastic bags, comprising a processing table, multiple support legs, four uprights, a top plate, a feeding assembly, a clamping assembly, a cutting assembly, and a conveying assembly. Support legs are fixedly connected to the four corners of the bottom of the processing table, and friction pads are provided at the bottom of the support legs. The feeding assembly is installed on the left end of the processing table. The four uprights are evenly installed on the top of the processing table, and a top plate is installed on the top of the uprights. Clamping assemblies are installed on the left and right sides of the top plate, and a cutting assembly is installed in the center of the top plate. A conveying assembly is installed on the right side of the processing table. Semi-finished plastic bags are conveyed to the top of the processing table via the feeding assembly. Conveying stops when the bags reach the cutting position. The clamping assembly clamps and fixes the left and right sides of the cutting area of ​​the semi-finished plastic bags to ensure cutting accuracy. The conveying assembly transports the cut semi-finished plastic bags, improving work continuity and processing efficiency.

[0005] Preferably, the feeding assembly includes a conveying roller, a vertical plate, two guide columns, two sliders, two springs, a pressure roller, a reducer, and a drive motor. A rotating groove is provided at the left end of the processing table, and the conveying roller is rotatably installed within it. The input end of the conveying roller is connected to the output end of the reducer, which in turn is connected to the output end of the drive motor. Vertical plates are installed on the front and rear sides of the top left end of the processing table.
