A search revealed a rubber composition and processing method disclosed in publication number CN108329559B on May 14, 2021. This design achieves good processing performance by optimizing the ratio of the rubber matrix and necessary components, making it suitable for rubber products with high requirements for aging resistance. However, this design primarily focuses on improving the material formulation, with less emphasis on enhancing the functionality of the mixing equipment itself. Traditional equipment may have limitations, especially when dealing with the need for efficient and uniform mixing of multiple raw materials. Furthermore, this solution does not address how to solve potential problems such as localized overheating or uneven material distribution during the mixing process, which could affect the performance stability of the final product.
[0003] Therefore, there is an urgent need to design a new type of mixing equipment for rubber product manufacturing to solve the above-mentioned problems of mixing efficiency and uniformity. Utility Model Content

The guide channels are used in conjunction with the guide plate.
[0009] Furthermore, the guide plate includes a first guide plate and a second guide plate, which are symmetrically arranged on both sides of the inner wall of the distribution plate. The first and second guide plates are connected to the inner wall of the distribution plate via a rotating shaft.

[0027] In this embodiment, the specific structure of the stirring device 2 is as follows: Figure 2As shown, the device consists of a rotating shaft 201, a first stirring blade 204, a second stirring blade 205, and a drive motor 202.

The drive motor 202 is located outside the main body 1 and is connected to the rotating shaft 201 through a bevel gear set 203 to provide power. During operation, the drive motor 202 drives the rotating shaft 201 to rotate through the bevel gear set 203, thereby causing the first stirring blade 204 and the second stirring blade 205 to move in tandem to complete the mixing operation of the materials.
[0029] Example 2
[0030] A cooling system 3 is provided based on Example 1.
[0031] In this embodiment, the structural details of the cooling system 3 are as follows: Figure 4 As shown, the system includes a cooling pipe 301. The cooling pipe 301 is wound inside the main body 1 of the equipment, with an inlet and an outlet at each end. The inlet and outlet are connected to an external cooling water source tank 302 via flanges. The cooling system 3 removes heat generated during equipment operation by circulating cooling water within the cooling pipe 301. A temperature sensor is mounted on the rotating shaft 201 and connected to the inlet and outlet of the cooling system via a signal line. The signal line passes through the outer wall of the main body 1 and is equipped with a waterproof sealing sleeve, used for real-time monitoring of the internal temperature of the equipment and adjustment of the cooling water flow rate.
[0032] Example 3
[0033] A material distribution component 4 is provided based on embodiment 2.
[0034] In this embodiment, the structure of the material distribution component 4 is as follows: Figure 3 As shown, it includes a distributing plate 401 and a guide plate 402. The distributing plate 401 is fixed to the top of the main body 1 and communicates with the stirring device 2.

The guide plate 402 is disposed inside the distributing plate 401 and is connected to the distributing plate 401 through a rotating shaft.
[0035] The guide plate 402 consists of a first guide plate and a second guide plate, which are symmetrically arranged on both sides of the inner wall of the distribution plate 401 and connected to the distribution plate 401 via a rotating shaft. The inner wall of the flow channel 404 within the distribution plate 401 is provided with flow-dividing teeth 405. These teeth 405 are vertically welded to the inner wall of the flow channel 404, with a height equal to half the depth of the flow channel 404, and their surfaces are polished to reduce frictional resistance. The spacing between the flow-dividing teeth 405 is equal, ensuring that the material is uniformly dispersed before entering the mixing device 2.
[0036] Example 4
[0037] Based on Example 3, a discharge port 5 is provided.
[0038] In this embodiment, the bottom of the equipment body 1 is provided with a discharge port 5, and a control valve 501 is installed at the discharge port 5. The control valve 501 is fixedly connected to the equipment body 1 by bolts. Below the discharge port 5, a collection trough 502 is provided, and the collection trough 502 is connected to the equipment body 1 by a bracket 503. The bracket 503 is fixed to the equipment body 1 by bolts. The inner wall of the equipment body 1 is provided with an anti-stick coating. The anti-stick coating has a uniform thickness and covers the entire inner wall, with a surface roughness of less than 0.1 micrometers, so as to reduce the adhesion of materials to the inner wall of the equipment. The presence of the anti-stick coating not only improves the mixing efficiency, but also facilitates the cleaning and maintenance of the equipment.
[0039] The working process of this utility model is as follows: First, various raw materials are fed into the equipment through the feed inlet 403 of the distribution plate 401. Under the action of gravity, the raw materials enter the guide channel 404 and are initially dispersed under the action of the diversion teeth 405. The guide plate 402 adjusts the angle according to actual needs by adjusting the bolts 14 to guide the raw materials to flow evenly to the stirring device 2. After the drive motor 202 is started, the rotating shaft 201 drives the first stirring blade 204 and the second stirring blade 205 to rotate synchronously. The spiral structure of the first stirring blade 204 pushes the material to move axially, while the arc design of the second stirring blade 205 causes the material to flow radially. The two blades work together to form a complex material flow path, thereby achieving efficient mixing. During this process, the temperature sensor monitors the internal temperature of the equipment in real time and transmits the data to the cooling system 3. The cooling system 3 adjusts the cooling water flow rate according to the temperature change to ensure that no local overheating occurs during the operation of the equipment. After mixing is completed, the control valve 501 is opened, and the material enters the collection tank 502 through the discharge port 5, completing the entire mixing process.
[0040] This invention achieves efficient mixing and uniform distribution of materials through the above-mentioned structural design, solving the limitations of traditional mixing equipment in the mixing of multiple raw materials. At the same time, it avoids local overheating and uneven material distribution, significantly improving the performance stability of rubber products.
[0041] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further supplemented below with a specific application scenario.
[0042] First, various rubber raw materials are fed into the equipment through the feed inlet 403 of the distribution plate 401. Under gravity, the raw materials enter the guide channel 404 and are initially dispersed by the flow-dividing teeth 405. The flow-dividing teeth 405 are vertically welded to the inner wall of the guide channel 404, with a height half the depth of the guide channel 404, and their surfaces are polished to reduce frictional resistance. The spacing between the flow-dividing teeth 405 is equal, ensuring that the material is uniformly dispersed before entering the mixing device 2. This step, through the structural design of the flow-dividing teeth 405, achieves initial homogenization of the material, avoiding the problem of uneven mixing caused by raw material accumulation in traditional equipment.
[0043] Subsequently, the angle of the guide plate 402 is adjusted according to actual needs. The first and second guide plates are respectively connected to the inner wall of the distribution plate 401 via rotating shafts. After the angle of the guide plates is adjusted, the raw materials flow evenly to the mixing device 2 along the guide channel 404. This step, through the adjustable design of the guide plates, ensures that raw materials of different types or densities can maintain a consistent distribution when entering the mixing device 2, thereby improving the uniformity of subsequent mixing.
[0044] After the drive motor 202 starts, the rotating shaft 201 drives the first stirring blade 204 and the second stirring blade 205 to rotate synchronously. The first stirring blade 204 is spirally arranged, with a pitch greater than the arc length of the second stirring blade 205. The two blades are arranged alternately along the axial direction of the rotating shaft 201. The spiral structure of the first stirring blade 204 propels the material to move axially, while the arc design of the second stirring blade 205 causes the material to flow radially. The two blades work together to form a complex material flow path, causing the material to continuously undergo axial and radial alternating movements inside the main body of the equipment 1. This process achieves multi-directional material flow through the unique design of the stirring blade assembly, solving the problem of low mixing efficiency caused by a single stirring method in traditional equipment.
[0045] During this process, the temperature sensor monitors the internal temperature of the equipment in real time and transmits the data to the cooling system 3. The cooling system 3 adjusts the cooling water flow rate according to the temperature change, and the cooling water in the cooling pipe 301 circulates to remove the heat generated during the operation of the equipment. This step effectively reduces the risk of local overheating during the operation of the equipment through the structural optimization of the cooling system, and avoids the deterioration of material properties caused by excessive temperature.
[0046] After mixing is complete, control valve 501 opens, and the material enters collection tank 502 through outlet 5. The inner wall of the main body 1 is coated with an anti-stick coating of uniform thickness, covering the entire inner wall, with a surface roughness of less than 0.1 micrometers, to reduce material adhesion to the inner wall of the equipment. The presence of the anti-stick coating not only improves mixing efficiency but also facilitates equipment cleaning and maintenance. This step, through the application of the anti-stick coating, reduces material residue, ensuring the continuous operation of the equipment and the stability of the mixing quality.
[0047] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.
[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
