Description

Technical Field

[0001] The utility model belongs to the technical field of rubber production, and in particular relates to a mixing device for producing rubber parts. Background Art

[0002] Rubber parts usually refer to components or products made of rubber materials. Rubber is a polymer material with good elasticity, good wear resistance, corrosion resistance, insulation and sealing properties, so it is widely used in various industrial and daily necessities.

[0003] The mixing in rubber parts production is usually carried out through a rubber mixer. The purpose of mixing is to fully mix the rubber raw materials with other additives to meet specific formulation requirements and make the rubber more plastic and uniform for subsequent molding and processing.

[0004] Patent CN219404915U discloses a rubber mixer for rubber production. When mixing rubber raw materials, the raw materials are added into a mixing tank through a feed box. Through the cooperation of a driving mechanism and a crushing mechanism, a connecting shaft can drive a crushing roller to rotate, thereby crushing the agglomerated raw materials.

[0005] Patent CN109224966A discloses a raw material mixer for rubber production, which mixes the raw materials evenly through a stirring rod on a rotating shaft. At the same time, gas can be blown into the air inlet channel through an air pump, and the gas is ejected from the air outlet hole on the stirring rod to make the additives adhered to the inner wall of the mixing cylinder fall down;

[0006] When the above scheme is used, various additives are mixed in a certain proportion and added into a mixing box through a feed box or a feed hopper. However, if the additives are only added into the mixing box through a feed box or a feed hopper, after the additives enter the mixing box, they cannot be evenly spread and the additives will accumulate on top of the rubber raw materials. After the mixing is completed, the additives mixed into the rubber raw materials at different positions will be different, resulting in uneven rubber quality. Utility Model Content

[0036] See also Figure 1 - Figure 4 As shown, a mixing device for producing rubber parts comprises a mixing box 1, and a first feeding pipe 11 is fixedly connected to the top of the mixing box 1, which is used to add rubber raw materials into the mixing box 1;

[0037] The top of the first feed pipe 11 is threadedly connected with a first sealing cover 12, which is used to seal the first feed pipe 11 to prevent impurities from entering the mixing box 1 and affecting the quality;

[0038] There are four support columns 15 in a circumferential array at the bottom of the mixing box 1 for supporting the mixing box 1;

[0039] A discharge pipe 16 is fixedly connected to the middle of the lower surface of the mixing box 1, and an electric valve 17 is arranged in the middle of the discharge pipe 16. After the rubber raw materials are mixed, the electric valve 17 is opened to discharge and collect the mixed rubber from the discharge pipe 16;

[0040] A motor 2 is provided in the middle of the upper part of the mixing box 1, and a rotating shaft 21 is connected to the output end of the motor 2. The rotating shaft 21 is rotatably connected to the inside of the mixing box 1. The rotating shaft 21 is located at the center of the mixing box 1. The motor 2 is used to drive the rotating shaft 21 to rotate;

[0041] An L-shaped mounting plate 4 is fixedly connected to the mixing box 1 at the position corresponding to the motor 2, and the motor 2 is mounted on the upper surface of the mounting plate 4 to support and fix the motor 2; the mounting plate 4 is set to be L-shaped to prevent the mounting plate 4 from obstructing the operation of the second pulley 39;

[0042] A plurality of stirring rods 22 in a circumferential array are connected to the outer side below the rotating shaft 21. The stirring rods 22 rotate in coordination with the rotating shaft 21 to mix and stir the rubber raw materials.

[0043] A scraper 23 is connected to one end of the stirring rod 22 close to the inner wall of the mixing box 1. The scraper 23 rotates with the rotating shaft 21 to scrape off the rubber raw materials adhering to the inner wall of the mixing box 1 during mixing.

[0044] Two symmetrically arranged positioning rings 3 are fixedly connected above the rotating shaft 21. The positioning rings 3 are located in the mixing box 1. A spreading plate 31 is provided between the two positioning rings 3. The middle part of the spreading plate 31 is rotatably connected to the outside of the rotating shaft 21. The positioning ring 3 is used to fix the position of the spreading plate 31 to prevent the spreading plate 31 from shifting. The spreading plate 31 is used to uniformly add additives such as vulcanizers, anti-aging agents, fillers, etc. into the mixing box 1 to mix with the rubber raw materials.

[0045] The bottom of the material spreading plate 31 is convex, so that the additives such as the vulcanizing agent, anti-aging agent, filler, etc. can be close to the inner wall of the material spreading plate 31 under the action of gravity, which plays a role in facilitating the spreading of the materials;

[0046] A plurality of partition plates 32 are arranged inside the material spreading plate 31 to divide the material spreading plate 31 into a plurality of areas. The arrangement of the partition plates 32 can prevent the additives in different areas from interfering with and crossing each other, thereby ensuring that the additives in each area remain independent during the material spreading process, and avoiding mixing and uneven distribution.

[0047] A plurality of discharge ports 33 are provided on the lower outer side of the material spreading plate 31, and each discharge port 33 is located between two adjacent partition plates 32, and is used to spread the additives from the discharge port 33;

[0048] The height of the partition plate 32 is lower than that of the material spreading plate 31, so as to prevent the additive from falling out from above the material spreading plate 31;

[0049] A second feed pipe 13 is obliquely arranged above the material spreading plate 31 for adding additives such as vulcanizing agent, anti-aging agent, filler, etc. into the material spreading plate 31;

[0050] The middle part of the second feed pipe 13 is connected to the mixing box 1, and the bottom of the second feed pipe 13 corresponds to the inside of the material spreading plate 31, ensuring that the additive can enter the material spreading plate 31;

[0051] The top of the second feed pipe 13 is threadedly connected with a second sealing cover 14, which is used to seal the second feed pipe 13 to prevent impurities from entering the mixing box 1 and affecting the quality;

[0052] A first gear 34 is fixedly connected to the outer side of the material spreading plate 31. The material spreading plate 31 can be rotated by using the first gear 34.

[0053] The first gear 34 is meshed with a second gear 35 on its outer side, and the first gear 34 can be rotated by the second gear 35;

[0054] A rotating rod 36 is fixedly connected to the middle of the upper surface of the second gear 35, and a bearing is fixedly connected to the outer side of the middle of the rotating rod 36. The bearing is installed on the top of the mixing box 1 to fix the rotating rod 36.

[0055] The upper end of the rotating rod 36 is fixedly connected to a first pulley 37, the inner side of the first pulley 37 is connected to one end of a belt 38, and the inner side of the other end of the belt 38 is connected to a second pulley 39, which is fixedly connected to the outer side above the rotating shaft 21;

[0056] During specific use, while the rotating shaft 21 rotates, it will drive the second pulley 39 to rotate, and the first pulley 37 will rotate in cooperation with the second pulley 39 and the connecting belt 38. The rotation of the first pulley 37 drives the second gear 35 to rotate. Because the second gear 35 is meshed with the first gear 34, the second gear 35 drives the first gear 34 to rotate, and the rotation direction of the second gear 35 is opposite to that of the first gear 34. The first gear 34 drives the spreading plate 31 to rotate, and the rotation direction of the spreading plate 31 is opposite to that of the rotating shaft 21. When the spreading plate 31 spreads additives, under the action of centrifugal force and gravity, the additives can be more evenly dispersed in the rubber raw material, thereby improving the quality of the product and ensuring the production of rubber products with better consistency.
