TECHNICAL FIELD

[0001] The present application relates to the technical field of planetary mixers, in particular to a liquid silicone rubber high-efficiency dispersion planetary mixer. BACKGROUND

[0002] Liquid silicone rubber is a liquid elastomer material with polysiloxane as the main chain, which has the convenience of liquid processing and the high performance characteristics of silicone rubber. In the production process, light lifting vacuum planetary mixers disclosed in the invention patents with announcement numbers CN102961994B and CN106956363B are used to disperse liquid silicone rubber and mix it with other raw materials.

[0003] However, it is found in use that the existing planetary mixers have a relatively simple structure, and it is not convenient to clean the residual liquid silicone rubber on the stirring shaft and the side wall of the stirring barrel after stirring. In addition, the lubricating oil used in negative pressure stirring is easy to penetrate into the stirring barrel, affecting the quality of the liquid silicone rubber, resulting in poor practicality. Therefore, there is an urgent need for a liquid silicone rubber high-efficiency dispersion planetary mixer to improve the above problems. SUMMARY

Then, the hydraulic cylinder 1 (6) extends, guiding the sealing cover 1 (7) via the guide column 2, so that the sealing cover 7 covers the top of the mixing tank 3. The drive motor 1 (10) is activated, causing the connecting shaft 13 to rotate. Through the meshing of the gear ring 1 (14), gear ring 2 (15), and multiple sets of gear rings 3 (17), the connecting shaft 13 drives the mixing shaft 11 to rotate, causing the multiple sets of rotating shaft sleeves 16 to respectively... Multiple sets of stirring shafts 12 rotate, and through the sealing cover 8, they rotate on the sealing cover 7, causing the multiple sets of stirring shafts 12 to rotate around the stirring shaft 11 while rotating on their own axis. This stirs the liquid silicone rubber in the mixing tank 3. After the liquid silicone rubber is mixed with other ingredients, the discharge valve 4 is opened to quickly discharge the liquid silicone rubber from the mixing tank 3. Then, the hydraulic cylinder 6 retracts, lifting the sealing cover 7. At the same time, the drive motor 10 is turned on to align the stirring shaft 11 with the corresponding perforations on the scraper 32. The hydraulic cylinder 21 extends and is driven by the motor 25. Through gear 26 and gear ring 24, the connecting shaft 23 rotates, inserting the polygonal shaft 27 into the polygonal groove 36. The hydraulic cylinder 21 continues to extend, separating the polygonal shaft 20 from the sealing cover 7. The motor 25 then continues to rotate, causing the stirring shaft 12 to rotate. Simultaneously, the rotation angle of the stirring shaft 12 is adjusted by the position sensor 35, ensuring proper contact between the stirring shaft 12 and the scraper. The corresponding perforations on 32 are aligned, and then the continuous contraction of hydraulic cylinder 6 causes the stirring shaft 11 and stirring shaft 2 12 to pass through scraper 32. The scraper 32 lifts and scrapes off the residue on the surface of stirring shaft 11 and stirring shaft 2 12. Then, the extension of hydraulic cylinder 6 resets stirring shaft 11 and stirring shaft 2 12. Then, the contraction of hydraulic cylinder 3 21, combined with the rotation of drive motor 2 25 and the elasticity of spring 28, causes the polygonal rotating shaft 2 30 to retract into the rotating shaft sleeve 16, thereby improving the practicality of the equipment.

[0050] Example 2: A high-efficiency planetary mixer for dispersing liquid silicone rubber, which further includes the following features in Example 1:

[0051] The negative pressure mechanism includes a pressure regulating cylinder 18, a piston 19, and a second hydraulic cylinder 20. The pressure regulating cylinder 18 is installed on the top of the outer shell 9, and the top of the pressure regulating cylinder 18 is provided with a ventilation hole. The interior of the pressure regulating cylinder 18 is connected to the interior of the outer shell 9. The piston 19 is slidably installed in the pressure regulating cylinder 18. The second hydraulic cylinder 20 is fixedly installed on the pressure regulating cylinder 18, and the bottom of the second hydraulic cylinder 20 is connected to the top of the piston 19.

[0052] The pressure regulating mechanism includes a vacuum pump 37 and a booster pump 38, both of which are mounted on the base 1.

[0053] Liquid silicone rubber and other ingredients are discharged into the mixing tank 3. The hydraulic cylinder 4 (33) retracts, covering the top of the mixing tank 3 with the support ring 31. Then, the hydraulic cylinder 1 (6) extends, guiding the sealing cover 1 (7) via the guide column 2, so that the sealing cover 1 (7) covers the top of the mixing tank 3. The drive motor 1 (10) is activated, causing the connecting shaft 1 (13) to rotate. Through the meshing of the gear ring 1 (14), gear ring 2 (15), and multiple sets of gear rings 3 (17), the connecting shaft 1 (13) drives the mixing shaft 1 (11) to rotate. This causes the multiple sets of rotating shaft sleeves 16 to drive the multiple sets of mixing shafts 2 (12) to rotate. The sealing cover 2 (8) rotates on the sealing cover 1 (7), causing the multiple sets of mixing shafts 2 (11) to rotate. 2. While rotating on its own axis, it rotates around the stirring shaft 11, thereby stirring the liquid silicone rubber in the mixing tank 3. At the same time, the vacuum pump 37 operates to expel air from the mixing tank 3, creating a negative pressure environment inside the mixing tank 3 to expel air bubbles from the liquid silicone rubber. Furthermore, when the vacuum pump 37 is running, the hydraulic cylinder 20 contracts, causing the piston 19 to rise and expel some air from the outer casing 9 into the pressure regulating cylinder 18, thus creating a negative pressure environment inside the outer casing 9 to prevent lubricating oil from entering the mixing tank 3. After the liquid silicone rubber is mixed with other ingredients, the booster pump 38 operates to expel air into the mixing tank. In step 3, the discharge valve 4 is opened to quickly discharge the liquid silicone rubber in the mixing tank 3. Then, the hydraulic cylinder 6 retracts, lifting the sealing cover 7. Simultaneously, the drive motor 10 is turned on to align the mixing shaft 11 with the corresponding perforation on the scraper 32. The hydraulic cylinder 21 extends, and the drive motor 25 operates, driving the connecting shaft 23 to rotate via gear 26 and gear ring 24. This inserts the polygonal rotating shaft 27 into the polygonal groove 36. The hydraulic cylinder 21 continues to extend, separating the polygonal rotating shaft 30 from the sealing cover 7. The drive motor 25 then continues to operate, causing the mixing shaft 12 to rotate. Simultaneously, by adjusting the rotation angle of the second stirring shaft 12 via the position sensor 35, the second stirring shaft 12 is aligned with the corresponding through holes on the scraper 32. Then, by the continuous contraction of the first hydraulic cylinder 6, the first stirring shaft 11 and the second stirring shaft 12 pass through the scraper 32. The scraper 32 lifts and scrapes off the residue on the surface of the first stirring shaft 11 and the second stirring shaft 12. Then, by extending the first hydraulic cylinder 6, the first stirring shaft 11 and the second stirring shaft 12 are reset. Then, by retracting the third hydraulic cylinder 21, and by the rotation of the second drive motor 25 in conjunction with the elasticity of the spring 28, the second polygonal rotating shaft 30 is retracted into the rotating shaft sleeve 16, thereby improving the practicality of the equipment.

[0054] The main functions achieved by this invention are:

[0055] 1. By cooperating with the cleaning mechanism and the stirring shaft, residues on the mixing tank and the stirring shaft are cleaned, improving the ease of equipment cleaning;

[0056] 2. The pressure inside the outer casing is regulated by a negative pressure mechanism to prevent lubricating oil from entering the mixing tank.
