[0031] Embodiment

[0032] As Figure 1 and Figure 2 As shown, the modified rubber seal mixing device proposed by the present utility model includes a bottom plate 1 and mixing rollers 3. The mixing rollers 3 are arranged on the bottom plate 1 and are used for mixing the modified rubber seal. It also includes two fixed seats 2 fixedly installed on the top of the bottom plate 1. The mixing rollers 3 are rotatably installed between the fixed seats 2. A speed reducer 8 is fixedly installed on one side of a fixed seat 2. The number of mixing rollers 3 is two and they are in transmission connection with the speed reducer 8. An installation frame 9 is fixedly installed on the top of the bottom plate 1. A rotating motor 10 with an output end in transmission connection with the speed reducer 8 is fixedly installed on the installation frame 9;

[0033] It is worth noting that the rotating motor 10 converts the high speed into a large torque force through the speed reducer 8 to drive the two mixing rollers 3 to rotate towards the opposite sides, and performs the mixing operation on the mixed raw materials;

[0034] In addition, fixing frames 4 are fixedly installed at the tops of both fixing seats 2. A support plate 5 is connected between the two fixing frames 4. A mixing bin 6 is fixedly installed on the bottom surface of the support plate 5. A feed hopper 7 is arranged on one side of the top of the mixing bin 6. The raw materials of the modified rubber seal and the additives are put into the mixing bin 6 through the feed hopper 7 for mixing. After mixing, the materials enter the tops of the two mixing rolls 3 from the discharge port at the bottom of the mixing bin 6 for mixing.

[0035] As Figures 1-4 shown, the device further includes a mixing device. The mixing device is arranged in the mixing bin 6 for uniform mixing of the raw materials. The mixing device includes a mixing rod 16 that slidably penetrates through the top of the mixing bin 6. A main stirring blade 18 is fixedly installed at the bottom end of the mixing rod 16. Two mounting blocks 19 are fixedly installed on the surface of the main stirring blade 18. Secondary stirring blades 20 are arranged on both of the two mounting blocks 19. The cooperation of the main stirring blade 18 and the secondary stirring blades 20 can make the stirring operation more uniform.

[0036] Furthermore, a chute 11 is fixedly installed on one side of the top of the support plate 5 close to the mixing bin 6. A slider 12 is slidably installed in the chute 11. A support frame 14 is fixedly connected to the slider 12. The mixing rod 16 is rotatably installed on the support frame 14. A motor 15 fixedly connected to the output shaft of the mixing rod 16 is fixedly installed at the top of the support frame 14. Starting the motor 15 can make the mixing rod 16 rotate to drive the rotation of the main stirring blade 18 and the secondary stirring blades 20, and mix and stir the raw materials inside the mixing bin 6.

[0037] Even further, a lead screw 17 threadedly connected to the slider 12 is rotatably installed in the chute 11. A drive motor 13 is fixedly installed at the top of the chute 11. The output shaft of the drive motor 13 is fixedly connected to the lead screw 17. Starting the drive motor 13 makes the lead screw 17 rotate, and the slider 12 can drive the mixing rod 16 to move downward, adjusting the stirring depth and realizing uniform stirring of the raw materials at different levels.

[0038] As Figures 2-4 shown, the device further includes a scraping device. The scraping device is connected to the mixing device for scraping the raw materials accumulated on the inner wall of the mixing bin 6. The scraping device includes a fixing rod 21 fixedly installed on the mixing rod 16 above the secondary stirring blade 20. A connecting piece 22 is installed on the fixing rod 21. A scraping rod 23 slidably connected to the inner wall of the mixing bin 6 is fixedly connected to the connecting piece 22. Multiple groups of breaking protrusions 24 are evenly arranged on the surface of the fixing rod 21.

[0039] It is worth mentioning that the slider 12 slides up and down along the slide groove 11, driving the scraper rod 23 to scrape up and down to clean the raw materials accumulated and attached on the inner wall of the mixing bin 6, avoiding the accumulation and blockage of the raw materials and affecting the discharge diameter area. At the same time, the rotation of the mixing rod 16 can also drive the breaking protrusion 24 to rotate and break up fine raw material particles, so that the mixing of the raw materials is more uniform, thereby improving the mixing effect.

[0040] like Figure 3 and Figure 4 As shown, the device also includes a dredging device, which is connected to the mixing device and is used for dredging and cleaning the bottom discharge port of the mixing bin 6. The dredging device includes a disc 25 fixedly mounted on the bottom end of the mixing rod 16, and a plurality of groups of friction protrusions 26 are arranged on the curved surface of the disc 25. A dredging needle 27 is fixedly mounted on the bottom of the disc 25. The height of the disc 25 is adjusted by the descending movement of the slider 12 so that the disc 25 is located near the discharge port at the bottom of the mixing bin 6. The dredging by the dredging needle 27 and the rotational friction of the friction protrusion 26 are combined to achieve dredging and cleaning of the bottom discharge port of the mixing bin 6, thereby improving the mixing efficiency.

[0041] Working principle: start the motor 15, so that the mixing rod 16 rotates and drives the main stirring blade 18 and the auxiliary stirring blade 20 to rotate and stir the raw materials in the mixing bin 6, so that the raw materials are stirred evenly, start the driving motor 13, so that the screw rod 17 rotates, and the slider 12 can slide along the slide groove 11, driving the mixing rod 16 to move downward to adjust the stirring depth of the main stirring blade 18 and the auxiliary stirring blade 20, so as to achieve uniform stirring of raw materials at different levels, and in the process of the slider 12 sliding up and down, the mixing rod 16 can drive the scraper 23 to scrape and clean the sticky raw materials accumulated on the inner wall of the mixing bin 6, so as to prevent the reduction of the diameter area of the mixing bin 6 from affecting the mixing efficiency, and at the same time, the horizontal height of the disc 25 can be adjusted by the descent of the slider 12, and the collision and dredging of the dredging needle 27 and the rotational friction of the friction protrusion 26 are combined to achieve the dredging and cleaning of the inner wall of the bottom discharge port of the mixing bin 6, avoid the blockage of the bottom discharge port of the mixing bin 6, and improve the overall mixing efficiency of the device.

[0042] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
