[0009] Preferably, an annular protrusion is provided on the inner wall of the mixing tank, and an annular groove is provided on the outer side of the inner gear ring.

[0010] Preferably, the scraper is a spiral structure.

[0011] Preferably, three scrapers are provided, and the three scrapers are evenly distributed along the circumference of the stirring tank.

[0012] Preferably, three groups of blades are provided on the stirring shaft, and the three groups of blades are evenly distributed along the height direction of the stirring shaft.

[0013] Beneficial technical effects of the utility model:

[0014] This utility model installs a scraper inside the mixing tank. The rotation of the agitator shaft drives the scraper to rotate synchronously, effectively scraping off the reclaimed rubber ingredients adhering to the inner wall of the mixing tank and mixing them with other reclaimed rubber ingredients in the tank, thereby achieving a more uniform mixing effect. The scraper adopts a spiral design. This structure not only helps to improve scraping efficiency, but also promotes the smooth separation of the scraped reclaimed rubber ingredients from the scraper surface, reducing the reclaimed rubber ingredients remaining on the scraper, and further improving the mixing quality and efficiency.

[0020] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0021] like Figure 1-Figure 4As shown, the device for uniformly mixing recycled rubber ingredients provided in this embodiment includes a stirring tank 1, a stirring shaft 2 is provided in the stirring tank 1, a main gear 3 is provided on the stirring shaft 2, an inner gear ring 4 is meshed on the outer periphery of the main gear 3, a scraper 5 is provided on the bottom surface of the inner gear ring 4, the outer side of the scraper 5 is attached to the inner wall of the stirring tank 1, a motor 6 connected to the stirring shaft 2 is provided on the outer side of the stirring tank 1, a feeding pipe 7 is provided on the top of the stirring tank 1, and a discharging pipe 8 is provided at the bottom of the stirring tank 1. When in use, the recycled rubber ingredients are added into the stirring tank 1 from the feeding pipe 7, and the motor 6 is started to make the stirring shaft 2 start stirring. At the same time, through the transmission of the main gear 3 and the inner gear ring 4, the scraper 5 starts to rotate, scraping off the recycled rubber ingredients adhering to the inner wall of the stirring tank 1, thereby achieving more uniform stirring.

[0022] In this embodiment, if Figure 4 As shown, an upper baffle 9 and a lower baffle 10 are respectively provided on the upper and lower sides of the inner gear ring 4. An upper through hole 11 and a lower through hole 12 for inserting the feed pipe 7 are respectively provided on the upper baffle 9 and the lower baffle 10, which protect the main gear 3 and the inner gear ring 4 and prevent the recycled rubber ingredients from entering and affecting the transmission.

[0023] In this embodiment, if Figure 3 As shown, two sub-gears 13 are symmetrically arranged between the main gear 3 and the inner ring gear 4, which improves the efficiency and stability of the transmission and ensures the continuity and consistency of the stirring process. A sub-gear positioning column 14 is arranged between the upper baffle 9 and the lower baffle 10 to fix the position of the sub-gear 13 and prevent dislocation due to vibration or impact.

[0024] In this embodiment, if Figure 2 As shown, an annular protrusion 15 is provided on the inner wall of the mixing tank 1, and an annular groove 16 is provided on the outer side of the inner gear ring 4 to provide support for the inner gear ring 4 and ensure that the inner gear ring 4 can rotate smoothly.

[0025] In this embodiment, if Figure 3 As shown, the scraper 5 is a spiral structure, which not only helps to scrape the material on the inner wall of the mixing tank 1, but also promotes the up and down flipping of the material to make the mixing more uniform.

[0026] In this embodiment, if Figure 3 As shown, three scrapers 5 are provided, and the three scrapers 5 are evenly distributed along the circumference of the mixing tank 1 to improve the scraping efficiency.

[0027] In this embodiment, if Figure 3 As shown, three groups of blades 17 are provided on the stirring shaft 2. The three groups of blades 17 are evenly distributed along the height direction of the stirring shaft 2, stirring the materials more comprehensively and improving the uniformity and efficiency of mixing.

[0028] In summary, in this embodiment, a scraper 5 is provided within the mixing tank 1. The rotation of the stirring shaft 2 drives the scraper 5 to rotate synchronously, effectively scraping off the reclaimed rubber ingredients adhering to the inner wall of the mixing tank 1 and mixing them with other reclaimed rubber ingredients within the tank, thereby achieving a more uniform stirring effect. The scraper 5 adopts a spiral design. This structure not only helps to improve scraping efficiency, but also promotes the smooth separation of the scraped reclaimed rubber ingredients from the surface of the scraper 5, reducing the reclaimed rubber ingredients remaining on the scraper 5, and further improving the stirring quality and efficiency.

[0029] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention based on the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
