Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1 to 7 As shown, a rubber mixing device includes a rubber mixing device body 1. A circular ring seat 2 is fixedly connected to the outer surface of the rubber mixing device body 1. A sliding ring 4 is rotatably installed inside the circular ring seat 2. A gear ring 5 is fixedly installed on the outer surface of the sliding ring 4.

A top seat 6 is fixedly provided on the upper side of the gear ring 5. Two guide posts 9 are fixedly connected to the upper side of the top seat 6. A clamping plate 10 is snapped onto the outer surface of the two guide posts 9.

[0031] Two symmetrically arranged scrapers 11 are fixedly connected to the lower side of the card plate 10. Fixed plates 12 are fixedly provided at both ends of the top seat 6. Telescopic plates 13 are slidably connected to one side of the two fixed plates 12. Two positioning round blocks 15 for fixing the card plate 10 are fixedly connected to the inner side of the two telescopic plates 13. Connecting springs 14 are arrayed between the two telescopic plates 13 and the fixed plates 12.

[0032] A side plate 3 is fixedly connected to the outer surface of the main body 1 of the rubber mixing device. A gear shaft 7 is rotatably connected to the upper side of the side plate 3. The gear shaft 7 meshes with the gear ring 5. The lower side of the gear shaft 7 passes through the side plate 3 and extends to the lower side of the side plate 3. A first servo motor 8 is fixedly installed on the lower side of the gear shaft 7 through a motor mounting plate.

[0033] The outer surface of the main body 1 of the rubber mixing device is respectively fixed with a first reinforcing plate 19 and a second reinforcing plate 20. The second reinforcing plate 20 is located below the first reinforcing plate 19. A threaded rotating rod 21 is rotatably connected between the first reinforcing plate 19 and the second reinforcing plate 20. A displacement plate 22 is threadedly connected to the outer surface of the threaded rotating rod 21. An L-shaped plate 23 is fixedly connected to one side of the displacement plate 22. A round seat 24 is fixedly provided on the lower side of the L-shaped plate 23. The round seat 24 is located directly above the main body 1 of the rubber mixing device. A sealing ring 18 is fixedly connected to the upper side of the main body 1 of the rubber mixing device. The sealing ring 18 can be adapted to the round seat 24 for assembly to facilitate rubber mixing.

[0034] A drive shaft 27 is rotatably connected to the lower side of the circular base 24. A stirring blade 29 and an inclined plate 30 are respectively arrayed on the outer surface of the drive shaft 27. The inclined plate 30 is located below the stirring blade 29, and one side of the inclined plate 30 is attached to the inclined plate 30. After the stirring blade 29 and the inclined plate 30 have finished mixing the rubber, the scraper 11 can be installed for cleaning. It is convenient to use. The upper side of the drive shaft 27 passes through the circular base 24 and extends to the upper side of the circular base 24. A third servo motor 28 is fixedly connected to the upper side of the drive shaft 27 through a motor mounting plate.

[0035] A feeding pipe 31 is fixedly installed on the lower side of the main body 1 of the rubber mixing device.

Two vertical rods 26 are fixedly connected between the first reinforcing plate 19 and the second reinforcing plate 20. The outer surfaces of the two vertical rods 26 are slidably connected to the inside of the displacement plate 22. Through the setting of the vertical rods 26, the movement trajectory of the displacement plate 22 can be limited and guided, so that the round seat 24 can move up and down smoothly and is easy to use. The lower side of the threaded rotating rod 21 passes through the first reinforcing plate 19 and extends to the lower side of the first reinforcing plate 19. A second servo motor 25 is fixedly installed on the lower side of the threaded rotating rod 21 through a motor mounting plate.

[0036] One side of the scraper 11 is attached to the inner wall of the rubber mixing device body 1. One side of the telescopic plate 13 passes through the fixed plate 12 and extends to the other side of the fixed plate 12. One side of each of the two telescopic plates 13 is fixedly connected to a support plate 16. By setting the support plate 16, moving the two support plates 16 can drive the elastic positioning block 15 away from the clamping plate 10, which is used to release the limit on the clamping plate 10 so that the two scrapers 11 can be removed. In this way, rubber mixing can be carried out. One side of the clamping plate 10 is threadedly connected to a fastening bolt 17 for fixing the clamping plate 10. By setting the fastening bolt 17, rotating the fastening bolt 17 can be used to squeeze and fix the clamping plate 10, ensuring the stability of the two scrapers 11 during use.

[0037] Two matching grooves 66 are provided at both ends of the card plate 10. The matching grooves 66 are matched with the positioning blocks 15. The outer surface of the positioning blocks 15 is slidably engaged with both ends of the card plate 10 through the matching grooves 66.

[0038] The lower side of the round seat 24 is provided with an annular groove 188, which is adapted to the sealing ring 18. The upper side of the sealing ring 18 is engaged with the lower side of the round seat 24 through the annular groove 188.

[0039] The working principle of the rubber mixing device provided by this utility model is as follows:

[0040] By attaching the clamping plate 10 to the two guide posts 9 at the top seat 6, the clamping plate 10 can drive the two scrapers 11 to fit into the interior of the rubber mixing device body 1. At this time, the clamping plate 10 can squeeze the two telescopic plates 13 with connecting springs 14 installed. In this way, the elastic force of the connecting springs 14 can make the positioning block 15 automatically extend and engage with the matching groove 66 at the clamping plate 10, which is used to further securely engage and fix the two scrapers 11. Then, the output shaft of the first servo motor 8 drives the gear shaft 7 to rotate. The gear shaft 7 can drive the gear ring 5 with the sliding ring 4 installed to rotate and adjust in the ring seat 2. As the gear ring 5 rotates, it can drive the two scrapers 11 to continuously scrape off the rubber residues attached to the inner wall of the rubber mixing device, which is used to effectively clean the rubber residues, ensure the output of the mixing device during mixing, and improve the cleaning efficiency of the rubber mixing device for rubber residues.

[0041] By driving the threaded rod 21 to rotate via the output shaft of the second servo motor 25, the displacement plate 22 on the threaded rod 21 can move downwards. This allows the displacement plate 22 to lower the circular seat 24 at the L-shaped plate 23 to above the main body 1 of the rubber mixing device, facilitating rubber mixing. Next, the output shaft of the third servo motor 28 drives the active rotating shaft 27 to rotate, allowing the stirring blades 29 and inclined plates 30 on the active rotating shaft 27 to stir and mix the rubber and rubber additives. At the same time, the shape of the inclined plates 30 can better fit the bottom of the rubber mixing device to achieve uniform rubber mixing. Subsequently, when the output shaft of the third servo motor 28 drives the threaded rod 21 to reverse, the stirring blades 29 and inclined plates 30 can be raised to a higher position, making it easier to clean the residual rubber on the stirring blades 29 and inclined plates 30, preventing excessive residual rubber from affecting the rubber mixing and improving the mixing effect of the mixing device.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
