[0002] Plastic products have become an indispensable daily necessity in people's daily lives and can be seen everywhere in production and life. PVC plastic is a polymer material that uses a chlorine atom to replace a hydrogen atom in polyethylene. Its natural color is slightly yellow and translucent, shiny, and its transparency is better than polyethylene and polypropylene, but worse than polystyrene. Depending on the amount of additives used, it is divided into soft and hard polyvinyl chloride. Soft products are soft and tough, and feel sticky. The hardness of hard products is higher than low-density polyethylene, but lower than polypropylene. Whitening will occur at the bend. Common products include: plates, pipes, soles, toys, doors and windows, wire sheaths, and stationery.

[0003] In the production process of PVC products, in order to improve the performance of its products, various additives, such as high-temperature resistant additives, are often needed. When mixing the additives with PVC, a stirring device is needed. When the existing stirring equipment is used to load the additives, the additives are generally loaded in piles. A large amount of additives accumulates inside the stirrer, which is not convenient for fully mixing the additives with the PVC raw materials, thereby reducing the production quality of PVC products. To this end, we propose a PVC high-temperature resistant additive stirring device to solve the above problems. Utility Model Content
