[0002] The main reason for using a dehumidifier dryer in the injection molding process is to ensure that the plastic raw materials have the right humidity before processing. Plastic raw materials, especially hygroscopic plastics such as nylon, polycarbonate, polyester, etc., easily absorb moisture from the environment, which eventually leads to significant quality problems in the injection molded products.

[0003] In order to ensure that hot air is in full contact with the plastic raw materials, some dehumidification dryers in the prior art are generally provided with a stirring structure. The stirring structure is generally a long-axis stirring structure driven by a motor to rotate, and the axis position of the stirring structure remains stationary. The stirred plastic raw materials are prone to generate vortices, and eventually a stirring dead zone is generated. The plastic raw materials in the stirring dead zone cannot be dehumidified and dried. Summary of the invention

The existence of the cantilever plate 13 creates an installation space between the top seat 12 and the base 5 for installing the central motor 11.

[0021] A material storage pot 4 is fixedly installed at the output end of the central motor 11, and a vertical rod 81 is vertically fixedly installed on the top of the extended folding frame 8. The side of the vertical rod 81 faces the stirring component for uniformly stirring the materials in various parts of the material storage pot 4. The setting of the extended folding frame 8 introduces the stirring component to the upper side of the material storage pot 4, which facilitates the stirring rod 1 in the stirring component to extend into the inner cavity of the material storage pot 4.

[0022] A support rod 10 is fixedly provided on the top of the top seat 12, and a heating arc tube 9 is fixedly provided on the top of the support rod 10.

[0023] A guide block 6 is movably inserted into the top of the stirring rod 1, and the guide block 6 is rotatably connected to the top of the side of the extension folding frame 8. The guide block 6 is provided with an empty groove for facilitating the stirring rod 1 to slide along the guide block 6. The contact position between the side wall of the empty groove and the stirring rod 1 is polished into a smooth surface to reduce the energy loss of the stirring rod 1 sliding along the guide block 6. Stirring blades 3 are equidistantly arranged at the end of the stirring rod 1. The heating arc tube 9 is filled with resistance wire. The external control device of the resistance wire is in the prior art and is therefore not disclosed in the present application document.
