[0002] Plastic powder is the material for the spraying process. Simply put, plastic powder is heated at high temperature and then sprayed onto the surface of the material by the air given by compressed air. During the production of plastic powder, raw materials such as solid resin, pigments, fillers, and additives need to be mixed in proportion.

[0003] After retrieval, the publication number is CN219051179U, which discloses a raw material mixing and proportioning device for plastic powder. By loading the raw materials into the shunt barrel and discharging them while rotating, various raw materials can fall more evenly at the bottom of the mixing tank, avoiding the accumulation of a single raw material in one place, thus greatly reducing the pressure of stirring and mixing, having a good mixing effect, and improving the mixing efficiency.

[0004] In the process of implementing the present utility model, the inventor found that at least the following problems in the prior art have not been solved. In the above case during use, the discharge amount of the plastic powder raw materials inside the shunt barrel cannot be controlled. If the plastic powder raw materials are discharged too fast, they will still pile up together, affecting the mixing effect.

[0005] Therefore, we propose a raw material proportioning device for plastic powder, which can solve the above problems. Content of the Utility Model

The feeding chute is annularly and evenly opened on the inner wall of the top of the proportioning cavity, a connecting groove is opened in the middle of the upper end of the proportioning housing, the outer side of the large gear is engaged with the small gear, one end of the first connecting rod placed inside the connecting groove vertically penetrates through the middle of the large gear and is fixedly connected to the large gear, one end of the second connecting rod placed inside the connecting groove on the top inner wall of the feeding chute penetrates through the middle of the small gear and is fixedly connected to the small gear, and a spiral conveyor blade is fixedly connected to the outer side of the lower end of the second connecting rod.

The middle part of the bottom side of the raw material cylinder penetrates and is fixedly installed with a material guiding pipe, and the discharging end of the material guiding pipe communicates with the upper end of the material guiding groove.

[0009] As an alternative solution of the technical solution of the present application, a valve is arranged inside the material guiding pipe, and the raw material cylinder communicates with the material guiding groove through the material guiding pipe.
