Description

Technical Field

[0001] The utility model relates to the technical field of plastic film processing, in particular to a loading and unloading structure for plastic film processing. Background Art

[0002] Plastic film processing is a common plastic processing method, which is widely used in packaging, construction, agriculture and other fields. Commonly used plastic raw materials include polyethylene, polypropylene, polyvinyl chloride, etc. Suitable plastic raw materials are selected according to different product requirements. The raw materials usually exist in the form of particles or powders and need to be prepared by melting, mixing and other processing methods. People then feed the prepared plastic raw materials into the extruder. The extruder is a key equipment for plastic film processing. It is mainly composed of a hopper, a screw, a heating system and other parts. The raw materials enter the screw chamber of the extruder through the hopper. The screw heats, melts and plasticizes the plastic raw materials by rotating to make it an extrudable melt. The feeding port of the extruder is usually on the upper side of the extruder. If manual feeding is used, not only the feeding speed is slow, but also the workload of the staff will be greatly increased. If the worker's feeding is unstable, it will lead to empty squeezing in the production process, which not only wastes raw materials but also affects production efficiency. Therefore, how to make feeding easy and convenient, and stable feeding is urgently needed to be solved. Therefore, a loading and unloading structure for plastic film processing is proposed here to solve the above problems. Utility Model Content
