A third feeder 4 is provided on the third support frame 13. The horizontal position at the top of the third feeder 4 is lower than the horizontal positions at the bottoms of the first support frame 11 and the second support frame 12. This structure enables the first guide pipe 22 and the second guide pipe 32 to be connected to the top of the third feeder 4. After the materials in the first feeder 2 and the second feeder 3 are mixed and stirred, they can enter the third feeder 4 through the first guide pipe 22 and the second guide pipe 32. A third stirring motor 41 is provided at the top of the third feeder 4. A feeding pipe 42 is provided at the bottom of the third feeder 4, including an extrusion pipe 5. The feeding pipe 42 is connected to the extrusion pipe 5. A controller 51 is provided on the extrusion pipe 5. The controller 51 can control the feeding amount of the feeding pipe 42. The materials are continuously stirred in the third feeder 4, and finally the materials are quantitatively fed into the extrusion pipe 5 through the feeding pipe 42. In the present utility model, the first feeder 2, the second feeder 3, and the third feeder 4 are connected in an up - and - down orientation to form a multi - stage mixing and feeding structure, reducing the time for mixing and stirring and improving the feeding efficiency.

[0022] A first feeding device 2 is provided with a first feed pipe 23, and the first feed pipe 23 is used to feed solid materials into the first feeding device 2. The first feeding device 2 can be used for mixing and stirring solid materials such as plastic particles. A plurality of first feed pipes 23 are provided, and various solid materials of different colors or various materials can be fed simultaneously.

[0023] A second feeding device 3 is provided with a second feed pipe 33, and the second feed pipe 33 is used to feed fluid materials into the second feeding device 3. The second feeding device 3 can be used for mixing and stirring fluid materials such as silicone raw materials. A plurality of second feed pipes 33 are provided, and various materials can be injected for mixing and stirring.

[0024] A third feeding device 4 is provided with a plurality of third feed pipes 43. The third feed pipes 43 can respectively inject hot water, chemical reagents, phosphor powder, etc., to adjust the consistency and color of the materials in the third feeding device 4.

[0025] A spray head 431 connected to the third feed pipe 43 is provided inside the third feeding device 4. When hot water is injected into the third feed pipe 43, the spray head 431 can be assembled to increase the spraying range.

[0026] The internal space of the third feeding device 4 is sequentially provided with three parts: an upper layer 401, a middle layer 402, and a lower layer 403. A stirring device connected to a third stirring motor 41 is provided inside the third feeding device 4, and the stirring device is sequentially provided with a first stirring paddle 44, a second stirring paddle 45, and a third stirring paddle 46. The upper layer 401 and the middle layer 402 form a first-stage funnel shape, and the middle layer 402, the lower layer 403, and the feeding pipe 42 form a second-stage funnel shape. The materials fed into the third feeding device 4 through the first guide pipe 22 and the second guide pipe 32 are continuously stirred inside the third feeding device 4. The flow rate of the feeding pipe 42 is controlled by a controller 51, so that the materials after mixing and stirring are quantitatively fed into an extrusion pipe 5. The stirring speed is fast and the feeding efficiency is high.

[0027] Specifically, the first stirring paddle 44 is located in the upper layer 401. The first stirring paddle 44 is triangular and is used to scrape off the materials fed through the first guide pipe 22 and the second guide pipe 32. One side of the first stirring paddle 44 is attached to the inner wall of the first feeding device 2, and the materials attached to the inner wall of the third feeding device 4 can be scraped off to prevent the materials from remaining in the upper layer 401.

[0028] The second stirring paddle 45 is located in the middle layer 402. The second stirring paddle 45 is columnar and is used for mixing and stirring. The middle layer 402 part inside the third feeding device 4 is the main mixing and stirring area, and the second stirring paddle 45 can mix and continuously stir the materials.

[0029] The third stirring paddle 46 is located in the lower layer 403. The third stirring paddle 46 is triangular and is used for mixing materials and cleaning the materials remaining in the lower layer 403. When the feeding pipe 42 is opened to feed the extrusion pipe 5, the third stirring motor 41 drives the third stirring paddle 46 to rotate continuously, facilitating the precise and rapid entry of viscous materials into the feeding pipe 42.

[0030] A rubber pad 14 is provided at the bottom of the fixing plate 1. Under normal circumstances, the fixing plate 1 is installed and fixed on the ground. The vibration generated after the first stirring motor 21, the second stirring motor 31, and the third stirring motor 41 are started can be alleviated by the rubber pad 14, reducing the amplitude transmitted from the fixing plate 1 to the ground, thereby reducing the noise generated by the equipment.
