Description

Technical Field

[0001] The utility model belongs to the technical field of rubber production, and specifically relates to a rubber production mixing and processing device. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a very small external force, and can return to its original state after the external force is removed. Mixing is a process of using a rubber mixer to mix raw rubber or plasticized raw rubber with compounding agents into a mixed rubber. It is the most important production process in rubber processing. Essentially, it is a process of uniformly dispersing compounding agents in raw rubber. The granular compounding agents are in the dispersed phase, and the raw rubber is in the continuous phase.

[0003] After retrieval, CN218857384U discloses a mixing device for the production and processing of flame-retardant silicone rubber, including a support plate. One side of the upper surface of the support plate is fixedly connected with a filter box. One side of the outer surface of the filter box is fixedly connected with a feed pipe. The feed pipe penetrates through one side of the outer surface of the filter box and extends to one side of the inner wall of the filter box. A suction pump is installed on the upper surface of the support plate. For this mixing device for the production and processing of flame-retardant silicone rubber, through the settings of the suction pump, the suction pipe, the feed pipe, the mixing box and the filter box, during specific use, after heating, stirring and mixing the silicone rubber and raw materials to be mixed in the mixing box, the suction pump can send the stirred silicone rubber raw materials in the mixing box into the filter box through the feed pipe through the suction pipe for filtration.

[0004] However, through the exploration of the inventor, it is found that this technical solution still has at least the following defects: In the above device, the mixed rubber is sent to the filter box through the set feed pipe, suction pump and suction pipe for filtration. However, the mixed rubber is a solid substance. When using a suction pump to feed the mixed rubber, there is a problem that the material pipe is blocked, resulting in the material being unable to smoothly enter the filter box for filtration.

[0005] In view of this, the present utility model is specifically proposed. Content of the Utility Model

An activity groove 6 is opened on the outer wall of the top of the substrate 1. A sealing plate 7 is slidably connected to the inner wall of the activity groove 6. The top of the sealing plate 7 is in contact with the bottom of the mixing tank 2. A push-pull plate 8 is fixedly installed on one side of the sealing plate 7. A blanking port 21 is opened at the bottom of the substrate 1. The blanking port 21 is located directly below the mixing tank 2, and the diameter of the blanking port 21 is larger than that of the mixing tank 2. Symmetrically arranged support plates 3 are fixedly connected to the outer wall of the bottom of the substrate 1. The same blanking plate 5 is vertically slidably installed on the two support plates 3. A storage groove 14 is opened on the top of the blanking plate 5. Filter holes 15 are opened at equal intervals on the storage groove 14. The blanking plate 5 is located directly below the blanking port 21. After mixing is completed, the sealing plate 7 is pulled horizontally by the provided push-pull plate 8 and activity groove 6 until the sealing plate 7 moves to one side of the mixing tank 2, so that the mixed material can smoothly fall through the blanking port 21 onto the blanking plate 5 for filtration, avoiding blockage during the blanking process and ensuring the smooth progress of the blanking process. The same rotating shaft 10 is rotatably installed on the two support plates 3. A cam seat 11 is fixedly connected to the outer wall of the rotating shaft 10. The cam seat 11 is located directly below the blanking plate 5. One side of the left support plate 3 is fixedly connected to a mounting plate 12. A second driving motor 13 is fixedly installed on one side of the mounting plate 12. The output shaft of the second driving motor 13 is connected to the end of the rotating shaft 10 through a coupling. The second driving motor 13 is started to drive the rotating shaft 10 to rotate. The rotating shaft 10 drives the cam seat 11 to rotate. When the convex position of the cam seat 11 rotates to contact the bottom of the blanking plate 5, the blanking plate 5 can be lifted, so that the blanking plate 5 can perform vertical reciprocating motion. Cooperating with the provided filter holes 15, the mixed material after mixing can be discharged through the filter holes 15, and the waste and impurities formed during the mixing process stay on the blanking plate 5, achieving the effect of vibrating and screening materials.

[0028] In a specific embodiment, mounting grooves are formed in the inner walls on opposite sides of the mixing tank 2, and heating plates 20 are fixedly connected to the inner walls of the mounting grooves. A moving hole is formed in the middle of the top of the mixing tank 2, and a mixing shaft 16 is rotatably mounted on the inner wall of the moving hole. The bottom end of the mixing shaft 16 extends to the inner side of the bottom of the mixing tank 2, and stirring rods 17 are fixedly connected to the outer wall of the mixing shaft 16 at equal intervals and arranged in a surrounding manner. Fixing rods 18 are symmetrically fixedly connected to the outer wall of the mixing shaft 16. Arc-shaped scraping plates 19 are fixedly connected to one ends of the two fixing rods 18.

The first driving motor 9 drives the mixing shaft 16 to rotate, and the mixing shaft 16 drives the stirring rods 17 to rotate. The heating plates 20 play a role in heating, and cooperate with the stirring rods 17 to mix and stir the raw rubber and compounding agents to achieve the mixing effect. At the same time, the mixing shaft 16 drives the fixing rods 18 to rotate, and the fixing rods 18 drive the arc-shaped scraping plates 19 to slide on the inner wall of the mixing tank 2, so as to scrape off the residual materials on the inner wall of the mixing tank 2.

[0029] The implementation principle of a rubber production mixing and processing device in this embodiment is as follows:

[0030] During specific use, the raw rubber and compounding agents are put into the mixing tank 2 through the feed pipe 4. After the feeding is completed, the first driving motor 9 and the heating plates 20 are simultaneously started to work. The first driving motor 9 drives the mixing shaft 16 to rotate, and the mixing shaft 16 drives the stirring rods 17 to rotate. The heating plates 20 play a role in heating, and cooperate with the stirring rods 17 to mix and stir the raw rubber and compounding agents to achieve the mixing effect. At the same time, the mixing shaft 16 drives the fixing rods 18 to rotate, and the fixing rods 18 drive the arc-shaped scraping plates 19 to slide on the inner wall of the mixing tank 2, so as to scrape off the residual materials on the inner wall of the mixing tank 2. When the mixing is completed, the sealing plate 7 is pulled horizontally by the arranged push-pull plate 8 and the moving groove 6 until the sealing plate 7 moves to one side of the mixing tank 2, so that the mixed materials can smoothly fall through the blanking port 21 onto the blanking plate 5 for filtration, avoiding blockage during the blanking process and ensuring the smooth progress of the blanking process. Then, the second driving motor 13 is started to drive the rotating shaft 10 to rotate, and the rotating shaft 10 drives the cam seat 11 to rotate. When the protruding position of the cam seat 11 rotates to contact the bottom of the blanking plate 5, the blanking plate 5 can be lifted, so that the blanking plate 5 can perform vertical reciprocating motion. Cooperating with the arranged filtering holes 15, the mixed materials after mixing can be discharged through the filtering holes 15, and the waste materials and impurities formed during the mixing process stay on the blanking plate 5, achieving the effect of vibrating and screening materials.
