[0022] Embodiment 1

[0023] As Figures 1-3 shown, a raw material mixing mechanism for producing polystyrene boards according to the present invention includes a housing 1. A plurality of heating strips 16 are fixedly installed in the wall of the housing 1. The heating strips 16 are evenly distributed, making the temperature inside the housing 1 more uniform. By using the heating strips 16 to change and maintain the temperature inside the housing 1, it is more conducive to the mixing of raw materials. A feed inlet 17 is fixedly installed on the upper part of the housing 1. A cover 18 is rotatably installed on the upper end surface of the feed inlet 17. A discharge pipe 2 is provided at the lower part of the housing 1. The discharge pipe 2 is equipped with a solenoid valve 3. A connecting shaft 4 is vertically arranged inside the housing 1. A stirring screw 5 is vertically fixedly installed at the lower end of the connecting shaft 4. The stirring screw 5 extends into the discharge pipe 2. A fixed cylinder 6 is sleeved outside the discharge pipe 2. The fixed cylinder 6 is fixedly connected to the housing 1 through a connecting rod 7. The top end of the connecting shaft 4 is connected to a power mechanism. A stirring shaft 8 is vertically rotatably installed on the inner top surface of the housing 1. A plurality of L-shaped stirring members 9 are fixedly installed at the lower part of the stirring shaft 8. A driven gear 10 is fixedly installed at the upper end of the stirring shaft 8. A driving gear 11 meshing with the driven gear 10 is fixedly installed at the upper end of the connecting shaft 4. A tooth ring 12 is rotatably installed on the upper part of the inner wall of the housing 1. A cleaning member 13 is fixedly installed on the lower end surface of the tooth ring 12. The cross-section of the cleaning member 13 is wedge-shaped. The cleaning member 13 is slidably matched with the inner wall of the housing 1. The cleaning member 13 rotates to scrape the inner wall of the housing 1, cleaning the raw materials adhering to the inner wall of the housing 1 and making the cleaning of the housing 1 more convenient. The tooth ring 12 is connected to one of the driven gears 10 through a transmission mechanism. The transmission mechanism includes a transmission gear 15 rotatably installed on the inner top surface of the housing 1. The transmission gear 15 is respectively meshed with the tooth ring 12 and one of the driven gears 10. This device stirs the raw materials by setting the stirring shaft 8 and the stirring members 9, and sets the stirring screw 5 to cooperate with the fixed cylinder 6 to transport the raw materials from bottom to top, promoting the stirring and mixing of the raw materials and improving the quality of the raw materials.

[0024] Embodiment 2

[0025] As Figures 1-3 shown, the power mechanism is vertically and fixedly installed with a motor 14 on the upper wall of the housing 1. The output shaft of the motor 14 rotates through the housing 1. The output shaft of the motor 14 is fixedly connected to the top end of the connecting shaft 4. The motor 14 uses a servo motor that can rotate forward and backward. When the motor 14 rotates forward, it drives the stirring screw 5 to cooperate with the fixed cylinder 6 to work, and can transport the raw materials at the lower part of the housing 1 upward, making the raw materials move circularly, promoting stirring and blending, improving the quality of the raw materials. When the motor 14 rotates reversely, it can drive the stirring screw 5 to rotate reversely. The stirring screw 5 drives the raw materials to move downward, promoting the discharge of the raw materials, reducing blockage, and improving the discharging efficiency.

[0026] Working principle:

[0027] During use, various raw materials are fed into the housing 1 through the feed port 17. The cover 18 is closed. The heating strip 16 is controlled to start working to maintain the temperature in the housing 1 at an appropriate temperature. Then, the motor 14 is controlled to rotate forward. The motor 14 directly drives the stirring screw 5 to rotate forward through the connecting shaft 4. The stirring screw 5 cooperates with the fixed cylinder 6 to transport the raw materials at the bottom of the housing 1 upward, making the raw materials move circularly in the housing 1. The driving gear 11 rotates synchronously with the connecting shaft 4. The driving gear 11 drives the stirring shaft 8 and the stirring member 9 to rotate synchronously through the driven gear 10. The stirring shaft 8 and the stirring member 9 stir and blend the raw materials. At the same time, the driven gear 10 drives the toothed ring 12 to rotate through the transmission of the transmission gear 15. The toothed ring 12 drives the cleaning member 13 to rotate synchronously. The cleaning member 13 rotates to clean the inner wall of the housing 1. After the stirring and blending are completed, the motor 14 is controlled to rotate reversely. The solenoid valve 3 is opened, and the stirring screw 5 rotates reversely to drive the discharging.

[0028] The above is only the preferred embodiment of the present invention, and it is not intended to limit the present invention in any form; any ordinary technical personnel in the industry can smoothly implement the present invention as shown in the accompanying drawings of the specification and described above; however, any minor changes, modifications, and equivalent changes made by those skilled in the art within the scope of the technical solution of the present invention by using the technical content disclosed above are all equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications, and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
