[0002] Plastic is a polymer compound that is polymerized by addition polymerization or condensation polymerization with monomers as raw materials. It has a medium deformation resistance, between fiber and rubber. It is composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. The main component of plastic is resin. Resin refers to a polymer compound that has not been mixed with various additives. In the storage of plastic raw materials, plastic raw materials are easily dampened by absorbing surrounding moisture due to long-term static storage in a single environment. Moisture can also cause discoloration and strength reduction of plastic raw materials, affecting the quality of subsequent plastic processed products. Therefore, a drying device for plastic injection molding is needed, but some existing devices have low drying efficiency for plastic raw materials and are not very practical. To solve the above problems, we have launched the following device. Utility Model Content
