[0033] The stirring mechanism is detachably mounted on the mixing tank 10. The stirring mechanism includes a mounting part 20 and a rotatably mounted stirring part 30. The mounting part 20 is located on the outer side of the top of the mixing tank 10, and the stirring part 30 extends from the feed inlet 11 into the interior of the mixing tank 10.

[0034] The mounting portion 20 comprises a connecting plate 22 and an ear plate 23, the ear plate 23 is arranged on the outer side wall of the mixing tank 10, the latch 24 is movably arranged on the ear plate 23, and the connecting plate 22 is insertedly connected with the ear plate 23 and the connecting plate 22 is insertedly connected with the latch 24.

[0035] The feeding port 11 is used for adding raw material EPDM rubber particles and other additives, the stirring portion 30 extends into the mixing tank 10 from the feeding port 11 and can rotate in the mixing tank 10 to complete the stirring action; the connecting plate 22 of the mounting portion 20 is insertedly connected with the ear plate 23 and the stability of the mounting portion 20 is ensured by the latch 24.

[0036] Since the stirring mechanism is detachable, when the production batch is replaced or the mixing tank 10 needs to be thoroughly cleaned, the stirring mechanism can be quickly removed, thereby simplifying the cleaning process and reducing the risk of cross contamination;

[0037] When the stirring mechanism needs to be repaired or replaced, it can be detached from the mixing tank 10 without complex tools, greatly shortening the downtime and reducing the maintenance cost;

[0038] Different types of stirring mechanisms can be easily replaced according to different production process requirements, such as changing the shape of the stirring portion 30 to optimize the mixing effect between EPDM rubber particles and different types of additives.

[0039] As shown in Figure 3 , Figure 4 , Figure 6 , Figure 3 Fig. 1 shows a front view of the ear plate and the latch in the embodiment; Figure 4 Fig. 2 shows a top view of the mixing tank in the embodiment; Figure 6 Fig. 3 shows a side view of the stirring mechanism in the embodiment;

[0040] The ear plate 23 is symmetrically arranged, the ear plate 23 comprises a horizontal section 231 and a vertical section 232, the horizontal section 231 is fixedly connected with the side wall of the mixing tank 10, the vertical section 232 is arranged at one end of the horizontal section 231 away from the mixing tank 10, the horizontal section 231 is provided with a first insertion hole 2311 for the connecting plate 22 to pass through, the latch 24 is movably arranged on the vertical section 232 in parallel with the horizontal section 231, and the connecting plate 22 is provided with a second insertion hole 221 for the latch 24 to pass through.

[0041] The first insertion hole 2311 is arranged on the horizontal section 231 for the connecting plate 22 to pass through, achieving the preliminary positioning of the connecting plate 22, and the connecting plate 22 is connected with the latch 24 through the second insertion hole 221, thereby completing the connection between the entire stirring mechanism and the ear plate 23.

[0042] As shown in Figure 4As shown, there are two pins 24 on each side, and the multiple pins 24 can further ensure the stability of the installation of the connecting plate 22.

[0043] The pin 24 includes a gripping block 241, which is located on the side away from the mixing tank 10. A spring 25 is sleeved on the outer part of the pin 24 and between the ear plate 23 and the gripping block 241.

[0044] Spring 25 is sleeved on the outside of pin 24 and located between ear plate 23 and gripping block 241. The two ends of spring 25 are fixedly connected to vertical section 232 and gripping block 241 respectively. Spring 25 can automatically keep pin 24 in a fixed position when there is no external force, ensuring that pin 24 will not easily loosen or fall off.

[0045] The grip block 241 makes it easier for operators to grasp and move the pin 24, especially when the mixing mechanism needs to be frequently disassembled and reassembled, thus improving work efficiency.

[0046] During installation, external force is used to move the pin 24 to a position that does not affect the insertion of the connecting plate 22 into the first socket 2311. After the connecting plate 22 is inserted into the first socket 2311, the external force is removed, and the pin 24 is inserted into the second socket 221 of the connecting plate 22. After the pin 24 is inserted into place, the spring 25 will apply a constant pressure to prevent the spring 25 from slipping out accidentally, thus enhancing the safety and stability of the equipment.

[0053] The plurality of stirring rods 32 arranged at intervals on the main shaft 31 can realize multi-level stirring of the material, which helps to improve the mixing efficiency and uniformity and ensures that all ingredients can be fully mixed.

[0054] The U-shaped scraper 33 can rotate closely to the inner wall of the mixing tank 10, effectively scraping off the material adhering to the inner wall, avoiding waste of the material and reducing the workload of subsequent cleaning.

[0055] The stirring mechanism further comprises a motor 40, which is fixedly arranged at the top of the mounting part 20, and the output shaft of the motor 40 is connected with the main shaft 31 through the mounting part 20.

[0056] The motor 40 in the prior art drives the rotation of the main shaft 31, so that the stirring part 30 realizes the stirring action.
