Description

Technical Field

[0001] The present invention relates to the technical field of PVC film recycling, and specifically to a waste recycling device for a PVC film calender that can be slit. Background Art

[0002] PVC film recycling refers to the process of recycling the waste materials generated during the production of a PVC film calender. During the production of a PVC film calender, some waste materials such as products that do not meet the expected quality requirements, scraps, and chips are generated. If these waste materials are directly discarded, it will not only cause waste of resources but also may pollute the environment. Moreover, such PVC film waste materials are dirty, wrinkled, and damaged, and need to be slit and broken for subsequent recycling and processing.

[0003] The utility model with the publication number CN218857431U discloses a PVC film waste recycling device. Through the transmission of a worm and worm gear and the transmission of gears, the rotation speeds of the first crushing wheel and the second crushing wheel are faster, so that the PVC film can be crushed more quickly, thereby improving the recycling efficiency of the PVC film. The crushed PVC film is heated to preheat the PVC film, and then the stacked PVC film is extruded by an electric push rod to make the PVC film into blocks.

[0004] The utility model with the publication number CN204322353U discloses a waste recycling device for a PVC film calender. The edge materials generated by the calender are pressed by a pressing roller and guided to a feeding roller, then sent to a cutting roller for cutting and crushing, and finally recovered into a recovery bucket. With this structural design, the edge materials can be easily crushed without the need to additionally increase crushing equipment.

[0005] However, the above-mentioned recycling devices for PVC film waste still have the following problems in actual use: Although the crushing mechanism can assist in the recycling of PVC film waste, such PVC film waste is not recycled immediately. During the static storage process, it is easy to stick to dust and become dirty, and then it will carry impurities after being directly crushed during recycling, affecting the purity of the recycled materials. At the same time, due to wrinkles and damage of the PVC film waste, it occupies an area during recycling, affecting the efficiency of reprocessing.

[0006] Therefore, a waste recycling device for a PVC film calender that can be slit is proposed to solve the problems mentioned above. Summary of the Invention
