Description

Technical Field

[0001] This utility model relates to the field of rubber product processing technology, and in particular to a uniform mixing device for producing rubber brake diaphragms. Background Technology

[0002] The rubber compound mixing device for rubber brake diaphragm production is a specialized device used to uniformly mix the rubber compound during the production process of rubber brake diaphragms. Nitrile rubber has good oil resistance, wear resistance, aging resistance and sealing performance, and can maintain stable performance under different working environments. It is suitable for components in braking systems that come into contact with hydraulic oil or other oils.

[0003] However, when using existing rubber brake diaphragm production compound uniform mixing devices, the mixing plates are used to stir the materials placed in the mixing tank, and external heating is used to achieve uniform mixing. However, the mixed materials require a long time to be fully and uniformly mixed, resulting in low working efficiency. Increasing the number or area of ​​the mixing plates will cause slow start-up and make it difficult to achieve mixing in the initial stage. Therefore, a rubber brake diaphragm production compound uniform mixing device is needed. Utility Model Content

[0004] The purpose of this invention is to provide a uniform mixing device for producing rubber brake diaphragms, which solves the problems of low mixing efficiency and long initial start-up time in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a uniform mixing device for producing rubber brake diaphragms, comprising a mixing tank for holding mixed materials, a cover plate for sealing detachably connected to the top of the mixing tank, a rotary motor mounted on the top surface of the cover plate, the output end of the rotary motor penetrating the cover plate and connected to a rotating shaft inside the mixing tank, a first stirrer and a second stirrer for mixing materials provided on the outer wall of the rotating shaft, and a scraping component at one end of the first stirrer and the second stirrer that fits against the inner wall of the mixing tank to perform a scraping function.

[0006] Preferably, the first stirrer and the second stirrer are arranged alternately.

[0007] Preferably, the first stirrer includes a mixing rod and a stirring plate, the stirring plate being rotatably sleeved on the outer wall of the mixing rod.

[0008] Preferably, the stirring plates are provided in five groups, and the five groups of stirring plates are arranged at equal intervals.

[0009] Preferably, the scraping assembly includes a scraper sleeve, a spring, and a scraper blade, with the scraper sleeve and the scraper blade forming an elastic connection via the spring.

[0010] Preferably, one side of the scraper sleeve has a groove that matches the scraper strip.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The rotating shaft driven by the rotary motor drives the first and second agitators to rotate inside the mixing tank, which can mix the materials. The mixing rod will initially stir the materials, and the mixing plate will also come into contact with the materials when the mixing rod rotates. The mixing is constantly rotating, and the first and second agitators are staggered to increase the contact area with the materials while reducing the number of parts, thereby improving the efficiency of uniform mixing of materials.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model relates to a device for uniformly mixing rubber compound for the production of rubber brake diaphragms, such as... Figure 1-5As shown, it includes a mixing tank 1. The materials to be mixed are placed inside the mixing tank 1. A cover plate 10 is detachably connected to the top of the mixing tank 1. After the materials are placed in, the cover plate 10 is installed to prevent the materials from splashing out during mixing.

[0021] Furthermore, a rotary motor 2 is installed on the top surface of the mixing tank 1. The output end of the rotary motor 2 passes through the cover plate 10 and is fixedly connected to the rotating shaft 3 inside the mixing tank 1. The rotary motor 2 can drive the rotating shaft 3 to rotate, thereby starting the mixing operation of the equipment.

[0022] Furthermore, a first stirrer 4 and a second stirrer 5 are fixedly connected to the outer wall of the rotating shaft 3. The first stirrer 4 and the second stirrer 5 are arranged alternately to reduce the number of mixing parts and increase the mixing area and the contact surface with the material, thereby improving the uniformity of mixing.

[0023] Among them, such as Figure 5 As shown, the first stirrer 4 includes a mixing rod 401 and a stirring plate 402. Five sets of stirring plates 402 are provided, and the five sets of stirring plates 402 are equidistantly sleeved on the outer wall of the mixing rod 401. The inner wall of the stirring plate 402 is rotatably connected to the outer wall of the mixing rod 401. When the mixing rod 401 stirs the material, the stirring plate 402 will rotate when in contact with the material, increasing the contact area and providing a mixing rate. The other end of the mixing rod 401 is fixedly connected to the outer wall of the rotating shaft 3. The function and structure of the second stirrer 5 are the same as those of the first stirrer 4.

[0024] Furthermore, a scraping component 6 is fixedly connected to one end of the first stirrer 4 and the second stirrer 5 away from the rotating shaft 3. When rotating, the scraping component 6 will adhere to the inner wall of the mixing tank 1 to prevent the material from adhering to the inner wall of the mixing tank 1, which would easily lead to material waste and make the material clump together after mixing and difficult to clean.

[0025] Among them, such as Figure 4 As shown, the scraping assembly 6 includes a scraper sleeve 601, a spring 602, and a scraper 603. The scraper sleeve 601 is elastically connected to the scraper 603 via the spring 602. The scraper sleeve 601 has a groove that matches the scraper 603. One end of the spring 602 is fixedly connected to the groove of the scraper sleeve 601, and the other end of the spring 602 is fixedly connected to the side wall of the scraper 603. The scraper 603 is tightly attached to the inner wall of the mixing tank 1 based on the elastic support of the spring 602, and plays the role of scraping away debris when rotating. The other side of the scraper sleeve 601 is fixedly connected to one end of the mixing rod 401.

[0026] Furthermore, a detection platform 7 is fixedly connected to the outer wall of the mixing tank 1, which can detect the operating status of the control equipment. A discharge pipe 8 is fixedly connected to the bottom middle of the mixing tank 1, which can be controlled to close by a solenoid valve, and plays the role of conveying the mixed materials. A pressure boosting pipe 9 is fixedly connected to the top of the cover plate 10. The pressure boosting pipe 9 is connected to an external pressure booster to pressurize the inside of the mixing tank 1 and accelerate the discharge of materials from the discharge pipe 8.

[0027] In practical use: the rotary motor 2 drives the rotary shaft 3 to rotate the first stirrer 4 and the second stirrer 5 inside the mixing tank 1, which can mix the materials. The mixing rod 401 will initially stir the materials, and the stirring plate 402 will also come into contact with the materials when the mixing rod 401 rotates. The stirring continuously rotates during the stirring process, and the first stirrer 4 and the second stirrer 5 are staggered to increase the contact area with the materials while reducing the number of parts, thereby improving the efficiency of uniform mixing of materials.
