Technical Field
[0001] This utility model relates to the field of tire raw material mixing technology, specifically a mixing device for tire production raw materials. Background Technology
[0002] Car tires are one of the most important components of a car. They come into direct contact with the road surface and, together with the car's suspension, mitigate the impacts that the car experiences while driving, ensuring good ride comfort and smooth driving. To improve the production efficiency of this device, a raw material mixing device for tire production is needed.
[0003] However, most existing mixing devices for tire production raw materials use a rotating mixing rod to mix the raw materials. However, the existing mixing method is not convenient for pouring the materials in the mixing drum. During the mixing process, the raw materials for automobile tires will stick to the inner wall of the mixing drum, so the inner wall of the mixing drum needs to be vibrated to clean them.
[0004] Therefore, we need a mixing device for tire production raw materials to solve the existing problem of mixing raw materials in tire production, and also to make the material adhering to the inner wall of the mixing tank fall off during the mixing process of tire production raw materials. Utility Model Content
[0005] The purpose of this utility model is to provide a mixing device for tire production raw materials, which solves the problem of mixing raw materials in existing tire production as mentioned in the background art, and also allows the material adhering to the inner wall of the mixing drum to fall off during the mixing process of tire production raw materials.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for tire production raw materials, including a hydraulic cylinder, the base of which is fixedly connected to the inner top surface of a support box, the output shaft end of which is provided with an integrally formed mixing blade, the surface of which is movably connected to the interior of a mixing barrel, the mixing barrel being disposed on the top surface of a bearing ring, the bottom surface of which is fixedly connected to the output shaft end of a drive motor, the base of which is fixedly connected to the inner bottom surface of the support box, and the outer surface of the mixing barrel having a retaining groove.
[0007] Preferably, the support box is provided with an integrally formed partition plate inside. The top surface of the partition plate is fixedly connected to the bottom of the bearing ring. The top surface of the bearing ring is provided with a positioning groove. A positioning rod is inserted into the surface of the positioning groove. The top surface of the positioning rod is fixedly connected to the bottom surface of the mixing tank.
[0008] Preferably, the bottom radius of the positioning rod is equal to the radius of the positioning groove, and there are four positioning rods arranged in a circular array along the central axis of the mixing tank.
[0009] Preferably, the mixing tank has an integrally formed arc-shaped protrusion inside, the surface of the arc-shaped protrusion contacts the surface of the striking ball, the surface of the striking ball is movably connected to the surface of the spring cavity, the spring cavity is opened inside the stabilizing rod, the end of the stabilizing rod is integrally formed on the surface of the output shaft of the hydraulic cylinder, and a return spring is provided on the surface of the spring cavity.
[0010] Preferably, the cross-section of the arc-shaped protrusion is arc-shaped, and there are several arc-shaped protrusions, which are evenly distributed at equal intervals along the central axis of the mixing tank.
[0011] Preferably, the cross-section of the spring cavity is convex, and the maximum radius of the surface of the spring cavity is smaller than the radius of the striking ball.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When the drive motor is started, the mixing drum on the top surface of the bearing ring rotates. A mixing blade is provided at the end of the output shaft of the hydraulic cylinder. When the hydraulic cylinder is started, the mixing blade retracts into the mixing drum. When the mixing drum rotates, the mixing blade mixes the tire material inside. After the tire material inside the mixing drum is mixed, the hydraulic cylinder is started to disengage the mixing blade at its bottom from the inside of the mixing drum. When the mixing drum rotates on the top surface of the bearing ring, it can be stably installed on the top surface of the bearing ring. Starting the drive motor allows the bearing ring to rotate automatically on the top surface of the partition, thus automatically mixing the tire material inside the mixing drum. There is no need to separately mix the material inside the mixing drum by rotating the mixing rod. The elasticity of the return spring allows the striking ball to continuously impact the surface of the arc-shaped protrusion, thus causing the tire material adhering to the inner surface of the mixing drum to fall off. This further solves the problem of raw material mixing in existing tire production processes and also enables the material adhering to the inner wall of the mixing drum to fall off during the tire production raw material mixing process.

They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] Example 1, please refer to Figures 1-5 This utility model provides a technical solution: a mixing device for tire production raw materials, including a hydraulic cylinder 3, the base of the hydraulic cylinder 3 being fixedly connected to the inner top surface of a support box 1, an integrally formed mixing blade 8 being provided at the end of the output shaft of the hydraulic cylinder 3, the surface of the mixing blade 8 being movably connected to the interior of a mixing tank 4, the mixing tank 4 being disposed on the top surface of a bearing ring 12, the bottom surface of the bearing ring 12 being fixedly connected to the end of the output shaft of a drive motor 7, the base of the drive motor 7 being fixedly connected to the inner bottom surface of the support box 1, and a retaining groove 9 being provided on the outer surface of the mixing tank 4, by fixing the end of the output shaft of the drive motor 7 to the bearing ring. The top surface of bearing ring 12 is then set with a mixing tank 4. When the drive motor 7 is started, the mixing tank 4 on the top surface of bearing ring 12 is rotated. A mixing blade 8 is set at the end of the output shaft of hydraulic cylinder 3. When hydraulic cylinder 3 is started, the mixing blade 8 can retract into the interior of mixing tank 4. When mixing tank 4 rotates, the tire material inside is mixed and stirred by the mixing blade 8. After the tire material inside mixing tank 4 is mixed and stirred, hydraulic cylinder 3 is started to disengage the mixing blade 8 at its bottom from the interior of mixing tank 4. The mixing tank 4 can be easily moved out of the support box 1 by using the snap-lock groove 9.
[0021] Example 2, see attached document Figures 1 to 5 Based on the first embodiment, in order to eliminate the need to stir the raw materials inside the mixing tank 4 by rotating the stirring rod, the support box 1 is provided with an integrally formed partition 2. The top surface of the partition 2 is fixedly connected to the bottom of the bearing ring 12. The top surface of the bearing ring 12 is provided with a positioning groove 11. A positioning rod 10 is inserted into the surface of the positioning groove 11. The top surface of the positioning rod 10 is fixedly connected to the bottom surface of the mixing tank 4.
[0022] By inserting the surface of the positioning rod 10 into the surface of the positioning groove 11, the mixing tank 4 can be stably installed on the top surface of the bearing ring 12 when the mixing tank 4 rotates on the top surface of the bearing ring 12. By starting the drive motor 7, the bearing ring 12 can be automatically rotated on the top surface of the partition plate 2. Therefore, the tire material inside the mixing tank 4 can be automatically mixed, without the need to separately mix the material inside the mixing tank 4 by rotating the mixing rod.
[0023] Example 3, refer to Appendix Figures 1 to 5 Based on Embodiment 2, in order to allow the tire material adhering to the inner surface of the mixing tank 4 to fall off, an integrally formed arc-shaped protrusion 6 is provided inside the mixing tank 4. The surface of the arc-shaped protrusion 6 contacts the surface of the striking ball 14. The surface of the striking ball 14 is movably connected to the surface of the spring cavity 13. The spring cavity 13 is opened inside the stabilizing rod 5. The end of the stabilizing rod 5 is integrally formed on the output shaft surface of the hydraulic cylinder 3. A return spring 15 is provided on the surface of the spring cavity 13.
[0024] By connecting the surface of the striking ball 14 to the surface of the spring cavity 13, and then setting a return spring 15 on the surface of the spring cavity 13, the striking ball 14 can strike the surface of the arc-shaped protrusion 6 by the elastic force of the return spring 15. When the mixing tank 4 rotates automatically on the top surface of the partition 2, the elastic force of the return spring 15 allows the striking ball 14 to continuously strike the surface of the arc-shaped protrusion 6, thus allowing the tire material adhering to the inner surface of the mixing tank 4 to fall off.
[0025] In actual use, the output shaft end of the drive motor 7 is fixedly connected to the top surface of the bearing ring 12, and then the mixing tank 4 is set on the top surface of the bearing ring 12. When the drive motor 7 is started, the mixing tank 4 on the top surface of the bearing ring 12 is rotated. A mixing blade 8 is set at the output shaft end of the hydraulic cylinder 3. When the hydraulic cylinder 3 is started, the mixing blade 8 can retract into the interior of the mixing tank 4. When the mixing tank 4 rotates, the tire material inside is mixed and stirred by the mixing blade 8. After the tire material inside the mixing tank 4 is mixed and stirred, the hydraulic cylinder 3 is started to disengage the mixing blade 8 at its bottom end from the interior of the mixing tank 4. The mixing tank 4 is then easily removed from the support box 1 by using the snap-fit groove 9. The surface of the positioning rod 10 is inserted into the surface of the positioning groove 11. When the mixing tank 4 is in the bearing ring 12... When the top surface rotates, the mixing tank 4 can be stably installed on the top surface of the bearing ring 12. By starting the drive motor 7, the bearing ring 12 can rotate automatically on the top surface of the partition 2. Therefore, the tire material inside the mixing tank 4 can be automatically mixed without the need to rotate the mixing rod to mix the material inside the mixing tank 4. By connecting the surface of the striking ball 14 to the surface of the spring cavity 13, and then setting a return spring 15 on the surface of the spring cavity 13, the elastic force of the return spring 15 can make the striking ball 14 hit the surface of the arc-shaped protrusion 6. When the mixing tank 4 rotates automatically on the top surface of the partition 2, the elastic force of the return spring 15 can make the striking ball 14 continuously hit the surface of the arc-shaped protrusion 6, so that the tire material adhering to the inner surface of the mixing tank 4 can fall off.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
