Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, specifically a mixing device based on the production of raw materials for self-healing tires. Background Technology

[0002] Self-sealing tires are a type of tire product that achieves their function by attaching a layer of soft, solid, gel-like polymer composite material (such as a special sealant layer) to the inner wall of the tire. When the tire is punctured by a sharp object, such as a nail, which is usually no more than 5 millimeters in diameter, this material can use its adhesiveness and elasticity to quickly wrap the foreign object or instantly seal the puncture after it is pulled out, preventing air leakage. This improves driving safety, reduces the hassle of tire repair, and helps to save space by eliminating the need for a spare tire. The raw materials required for producing self-sealing tires need to be mixed in a mixing tank, and the mixing device is one of the important components of the mixing tank.

[0003] However, current double S-type mixers generally use dead zones at the sides and bottom of the container, leading to material settling and uneven mixing. Therefore, those skilled in the art have provided a mixing device based on raw materials for producing self-healing tires to solve the problems mentioned in the background section. Summary of the Invention

[0004] The purpose of this invention is to provide a mixing device based on the production of raw materials for self-healing tires, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A mixing device for producing raw materials for self-healing tires includes a rotating shaft. At least one set of guide members are arranged circumferentially on the rotating shaft. Each guide member includes a top guide plate and a bottom guide plate, both of which are inclined in the same direction. A support plate is vertically arranged at the end of the guide member away from the rotating shaft. Several side guide plates are inclined on the support plate. The inclination direction of the side guide plates is opposite to that of the top and bottom guide plates.

[0006] As a further improvement of this utility model: a number of internal guide plates are installed between the top guide plate and the bottom guide plate on a set of guide components, and all of them are inclined around the vertical center line of the internal guide plate.

[0007] As a further improvement of this utility model, the two adjacent internal guide plates on the same set of guide components are tilted in opposite directions. This angle design can optimize the flow direction and speed of the material on the guide plate, effectively reduce flow resistance, improve stirring efficiency, and ensure that a stable circulating flow field can be formed in both forward and reverse rotation.

[0008] As a further embodiment of this utility model: the rotating shaft is provided with at least two sets of guide members in the circumferential direction, wherein the top guide plate and bottom guide plate in one set of guide members are inclined in opposite directions to the top guide plate and bottom guide plate in the other set of guide members.

[0009] As a further improvement of this utility model, the side guide plate, top guide plate, internal guide plate and bottom guide plate are rectangular, trapezoidal or fan-shaped, which provides flexibility for the specific design and manufacturing of the device. The most suitable guide plate form can be selected according to different material characteristics and the shape of the mixing tank to achieve the best stirring effect.

[0010] As a further improvement of this invention, the top end of the rotating shaft is connected to the output shaft of the drive motor, providing stable and controllable rotational power for the entire stirring device.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The top baffle collects and guides the material from the top to move downwards, while the bottom baffle and the side baffles at its ends scrape up and guide the material from the bottom and side walls. This combination ensures that the material can form an effective circulation within the mixing container, which can solve the problems of material sedimentation and uneven mixing, while avoiding dead zones in the mixing and effectively preventing component segregation or sedimentation.

[0014] 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.

[0015] Example 1: Please refer to Figures 1-4 In this embodiment of the invention, the rotating shaft 2 is circumferentially provided with two sets of guide members. Each guide member includes a top guide plate 3 and a bottom guide plate 5, both inclined in the same direction. The main function of the top guide plate 3 is to control the flow direction of the upper material. The inclined top guide plate 3 can effectively collect and guide the material at the top of the container to move downwards, thereby breaking any potential surface eddies and allowing the material to enter the main mixing area from above. The bottom guide plate 5 can handle materials that easily settle at the bottom of the container. Its inclined design allows it to scrape up and guide the material accumulated at the bottom and side walls upwards during rotation. This is crucial for preventing high-density or easily settling raw materials from forming sediment at the bottom of the container, ensuring sufficient vertical circulation of the material. A support plate is vertically arranged at the end of the guide member away from the rotating shaft 2. Several side guide plates 1 are inclinedly arranged on the support plate. The tilt direction of plate 1 is opposite to that of the top guide plate 3 and the bottom guide plate 5. The top guide plate 3 and the bottom guide plate 5 in one set of guide components are tilted in the opposite direction to the top guide plate 3 and the bottom guide plate 5 in another set of guide components. The side guide plate 1 is installed on the bearing plate at the end of the guide component. This reverse design enables it to guide the material flowing towards the side wall of the container. In conjunction with the main guide plate, it further eliminates the stirring dead corner near the container wall and enhances the local turbulence effect, improving the mixing uniformity. The symmetrical layout can ensure that the rotating shaft 2 is balanced when rotating, reducing vibration and energy consumption, improving the stability and service life of the device, and ensuring that the material is evenly transported to all sides. Several internal guide plates 4 are installed between the top guide plate 3 and the bottom guide plate 5 on one set of guide components, and they are all tilted around the vertical center line of the internal guide plate 4.

[0016] It should be noted that the two adjacent internal guide plates 4 on the same set of guide components are tilted in opposite directions. This angle design can optimize the flow direction and speed of the material on the guide plate, effectively reduce flow resistance, improve stirring efficiency, and ensure that a stable circulating flow field can be formed in both forward and reverse rotation.

[0017] Specifically, the side guide plate 1, top guide plate 3, inner guide plate 4, and bottom guide plate 5 are rectangular, trapezoidal, or fan-shaped, which provides flexibility for the specific design and manufacturing of the device. The most suitable guide plate form can be selected according to different material characteristics and the shape of the mixing tank to achieve the best mixing effect.

[0018] The top of the rotating shaft 2 is connected to the output shaft of the drive motor, providing stable and controllable rotational power for the entire stirring device.

[0019] In this embodiment, due to the symmetrical layout of the two sets of guide components, when the motor rotates in only one direction, one set of guide components generates upward flow, while the other set generates downward flow simultaneously. This naturally forms a pair of opposing and mutually impacting circulating flow fields inside the barrel. This allows the device to achieve omnidirectional mixing without the motor reversing direction. A bidirectional flow field can be generated simultaneously when the motor rotates in a single direction, resulting in higher mixing efficiency and shorter mixing time. The symmetrical layout of the guide components helps to balance the force on the rotating shaft 2 during rotation, reducing vibration and noise, and improving the stability and service life of the equipment.

[0020] It should be noted that the motor can also operate in forward and reverse rotation modes. In this case, the flow field will be periodically enhanced, resulting in a better mixing effect.

[0021] Example 2: The difference between this embodiment and embodiment 1 is that this embodiment only sets up one set of flow guides. The design points of this set of flow guides and their matching side flow guide 1 and internal flow guide 4 are the same as those of embodiment 1.

[0022] In this embodiment, with a set of guide components, the difference from embodiment 1 is that this embodiment requires the forward and reverse rotation of the motor to achieve the best stirring effect. Specifically, when the motor rotates forward, the bottom guide plate 5 and the side guide plate 1 work together to push the material at the bottom and edge of the bucket upward, while the top guide plate 3 guides the upper material to the center and conveys it downward. At the same time, the adjacent internal guide plates 4 with opposite inclination directions generate strong shearing and mixing in the middle of the bucket, forcing the material to form a circulating flow field from bottom to top and then from top to bottom in the vertical plane.

[0023] It should be noted that when the motor reverses, the flow direction is completely reversed. The top guide plate 3 and the side guide plate 1 work together to push the material towards the side and top of the barrel, while the bottom guide plate 5 lifts the material from the bottom center area upwards. The reverse-positioned internal guide plate 4 continues to ensure that the material in the middle of the barrel is fully mixed.

[0024] By rotating the motor in both directions, the material circulation direction within the mixing tank is periodically reversed. Combined with the reverse tilting design of the adjacent internal guide plate 4, this embodiment can very effectively break the flow layer and prevent the material from flowing along a fixed path within the tank, thereby greatly reducing mixing dead zones. It is particularly suitable for self-healing tire raw materials that are prone to sedimentation or have high viscosity. This configuration provides powerful mixing capabilities.

[0025] Example 3: Please see Figures 1-4 In this embodiment of the present invention, the difference between this embodiment and embodiment 2 is that the two adjacent internal guide plates 4 on the same group of guide members have the same tilt direction.

[0026] It should be noted that the vertical circulation flow field formed by the top, bottom and side guide plates during forward and reverse rotation is similar to that in Example 2. However, since all the internal guide plates 4 are tilted in the same direction, they will guide the material to flow in one main direction during stirring. The resulting flow field has relatively less flow resistance compared to Example 2. It is suitable for materials that are sensitive to shear force and require relatively gentle but continuous circulation mixing. At the same time, by switching the forward and reverse rotation of the motor, the directional deposition of materials in a single direction can still be effectively avoided.

[0027] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
