Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic packaging bag processing technology, specifically a cutting guide device for plastic packaging bags. Background Technology
[0002] Plastic packaging bags are bag-shaped containers made from plastic film used for packaging goods. Commonly used plastic materials include polyethylene, polypropylene, polyvinyl chloride, and polystyrene. They have advantages such as being lightweight, having good sealing properties, being moisture-proof, dust-proof, and resistant to chemical corrosion. They are widely used in packaging for food, daily necessities, industrial products, and other fields. They can be made into various shapes, sizes, and thicknesses as needed, and can undergo processing such as printing, bag making, and sealing. They greatly facilitate the storage, transportation, and sale of goods, but at the same time, they also bring about problems such as plastic pollution and recycling, which need to be taken seriously in the use and disposal process.
[0003] Authorization announcement number CN222769089U discloses a shearing and guiding device for plastic packaging bags. The technical solution is as follows: "It includes a base frame, a support plate fixedly installed at the bottom of the base frame, a rotary motor fixedly installed on the upper surface of the support plate, a connecting plate fixedly installed at the output end of the rotary motor, and a frame fixedly installed on the upper surface of the connecting plate." The beneficial effects are: it achieves the purpose of meeting different conveying positions of the packaging bag, and facilitates increasing the selection of movement guidance after shearing, thus avoiding the problem of only being able to convey in one direction after shearing.
[0004] The above technical solution has the following drawbacks: the discharge plate guides the cut plastic bags, but the discharge plate lacks limiting structures on both sides. Because the shearing and guiding device vibrates during operation, some plastic bags will tilt to the sides when the plastic bags are guided downwards, causing some plastic bags to fall to the ground and others to get stuck on the left side of the frame, thus affecting the efficiency of guiding and conveying the plastic bags. Therefore, a shearing and guiding device for plastic bags is proposed to solve the problems mentioned above. Utility Model Content
