Extrusion molding has the following characteristics: a continuous molding production process, high production efficiency, and a wide range of applications. During the production and processing of printing consumables, the consumables need to be dried.

[0003] For example, a material dryer for the production of 3D printing consumables with patent application number CN202022136202.2 includes a shell, a drying box is provided inside the shell, a heater is installed on the top of the drying box, a heating plate is installed on the inner wall of the drying box, and a gas separation chamber is provided on the upper right side of the interior of the drying box. Compared with the prior art, by setting a vibration plate, the material flowing into the drying box can flow onto the vibration plate for drying, which can effectively improve the comprehensive drying of the material and greatly improve the drying efficiency of the material.

[0004] In the actual use of the above material dryers for 3D printing consumables production, the materials can only be dried on the surface of the vibration plate inside the drying box, causing part of the materials to be accumulated at the bottom and unable to be fully and evenly dried, resulting in low material drying efficiency. For this reason, we designed a material dryer to improve the shortcomings of the above material dryers. Utility Model Content
