[0002] Bound rubber, also known as carbon black gel, refers to the rubber in carbon black compound that cannot be dissolved by good solvents. Its formation occurs through two pathways: chemical adsorption and physical adsorption. The amount of bound rubber formed is affected by factors such as the specific surface area of carbon black, the number of mixing passes, temperature, rubber properties, and aging time.
[0003] The existing technology has the following drawbacks: some existing mixing tanks stir the carbon black gel in a relatively unidirectional direction. Prolonged unidirectional stirring can easily lead to sedimentation of the carbon black gel, which affects its subsequent normal use and reduces the uniformity of the carbon black gel during storage. To address this issue, an anti-settling mixing tank for EPDM carbon black compound is proposed. Utility Model Content

[0032] Furthermore, a stirring rod 6 is fixedly connected to the bottom of the second gear 5, and a sliding plate 11 is slidably connected to the outer surface of the stirring rod 6. The second gear 5, during its rotation, drives the stirring rod 6 to rotate inside the mixing tank body 1, achieving a thorough stirring effect on the items placed inside the mixing tank body 1. An electric telescopic rod 10 is fixedly connected to the bottom of the sliding plate 11, and the bottom of the electric telescopic rod 10 is fixedly connected to the top of the mixing tank body 1. A connecting rod 12 is rotatably connected to the bottom of the sliding plate 11. The operation of the electric telescopic rod 10 drives the sliding plate 11 to slide on the outer surface of the second gear 5. A scraper 8 is fixedly connected to the side wall of the stirring rod 6. The stirring rod 6 is rotatably connected inside the mixing tank body 1, and the side wall of the scraper 8 contacts the inner side wall of the mixing tank body 1. Rotating the stirring rod 6 drives the scraper 8 to rotate, and the rotating scraper 8 cleans the material remaining on the inner side wall of the mixing tank body 1. A cleaning mechanism 7 is provided on the outer surface of the stirring rod 6.
[0033] Reference Figures 1-3 The cleaning mechanism 7 includes a lifting rod 71. The bottom of the connecting rod 12 is rotatably connected to the top of the lifting rod 71. The lifting rod 71 is slidably connected to the outer surface of the stirring rod 6. When the sliding plate 11 slides on the outer surface of the second gear 5, it drives the connecting rod 12 to drive the lifting rod 71 to slide on the outer surface of the stirring rod 6. A fixing rod 72 is fixedly connected to the outer surface of the stirring rod 6. A cleaning rod 73 is hinged to the end of the lifting rod 71. During the descent, the lifting rod 71 is pushed by the fixing rod 72. After being pushed, the lifting rod 71 drives the cleaning rod 73 to slide and clean the outer surface of the stirring rod 6. The end of the fixing rod 72 is hinged to the side wall of the lifting rod 71. The cleaning rod 73 is slidably connected to the outer surface of the stirring rod 6. Stirring blades are provided on both the front and rear sides of the cleaning rod 73.

The cleaning rod 73 is used to drive the stirring blades to move during the moving process, and the stirring blades are used to fully stir the carbon black compound.
[0034] Reference Figures 2-4The feeding assembly 9 includes a rotating rod 91, the top of which is fixedly connected to the bottom of the first gear 4, and a striking plate 92 is fixedly connected to the bottom of the rotating rod 91. The rotating rod 91 is driven to rotate by the rotating first gear 4, and the rotating rod 91 drives the striking plate 92 to rotate during the rotation process. The feeding box 2 is elastically connected to the feeding plate 93 through a return spring 94. After the feeding plate 93 is struck, it compresses the return spring 94, causing the return spring 94 to deform. During the reset, the rebound of the return spring 94 drives the feeding plate 93 to slide and reset. The side wall of the striking plate 92 is in contact with the side wall of the feeding plate 93, and the feeding plate 93 is slidably connected inside the feeding box 2. The striking plate 92 during the rotation process has a rotating and striking effect on the feeding plate 93. The feeding plate 93 has a connecting hole inside, which allows the liquid inside the feeding box 2 to be fed.
[0035] Working principle: In use, the carbon black compound to be placed is put into the interior of the mixing tank 1 through the feeding port opened at the top of the mixing tank 1. Then, the servo motor 3 drives the first gear 4 to rotate, the rotation of the first gear 4 drives the second gear 5 to rotate, and the rotation of the second gear 5 drives the stirring rod 6 to rotate, thereby satisfying the mixing of the carbon black compound inside the mixing tank 1. At the same time, the rotating stirring rod 6 drives the scraper 8 to rotate, which has the effect of scraping and cleaning the inner wall of the mixing tank 1. When the carbon black compound stored inside the mixing tank 1 settles, the operation of the electric telescopic rod 10 drives the sliding plate 11 to slide on the outer surface of the stirring rod 6, thereby driving the connecting rod 12 to descend. The descent of the connecting rod 12 drives the lifting rod 71 to descend. During the descent of the lifting rod 71, it is pushed by the fixed rod 72, thereby driving the cleaning rod 73 to slide on the outer surface of the stirring rod 6, and at the same time driving the stirring plate to move, so as to fully mix the carbon black compound inside the mixing tank 1 and improve the uniformity of the carbon black compound during the mixing process.
[0036] Simultaneously, the material to be fed is fed into the inside of the feeding box 2 through the feeding port opened at the top of the feeding box 2. At the same time, the operation of the servo motor 3 drives the first gear 4 and the rotating rod 91 to rotate. The rotation of the rotating rod 91 drives the tapping plate 92 to rotate. The rotation of the tapping plate 92 taps the feeding plate 93. After being tapped, the feeding plate 93 compresses the reset spring 94 and drives the connecting hole to contact the feeding port inside the feeding box 2, thereby satisfying the requirement of discharging the material inside the feeding box 2 and achieving the effect of uniform feeding of the material.
