They are an indispensable part of modern industry and are widely used in many fields such as home appliances, automobiles, electronics, medical equipment, etc. Plastic parts have the advantages of light weight, short molding cycle and high molding precision.

[0003] After plastic parts are injected, they are dried to remove moisture and oil on the surface of the plastic parts and improve the surface quality and gloss of the plastic parts. Currently, plastic parts are dried by plastic dryers. Plastic dryers use hot air circulation to evenly blow hot air to the surface and inside of plastic parts, thereby quickly evaporating and removing residual moisture. At the same time, the dryer can also control temperature and humidity to ensure that the plastic parts will not be damaged during the drying process.

[0004] There are two feeding methods for plastic dryers currently in use:

[0005] 1. Shelf type: There are several shelves in the plastic dryer. Before drying, the shelves need to be taken out, the plastic parts placed, and then the shelves are put back, which is inefficient;

[0006] 2. Cart type: Place the plastic parts on the rack on the cart and push the cart into the dryer. However, the cart needs to be lifted to enter the dryer. The lifting process is unstable and the plastic parts placed on it are prone to shaking or even falling, affecting the quality of the plastic parts. Summary of the invention
