[0001] This utility model belongs to the field of tire processing technology, and more specifically, relates to a raw material preparation device for rubber tires. Background Technology

[0002] Tires are circular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. Tires require multiple processing steps during production. First, the raw materials for tires need to be processed and mixed. In addition to natural rubber, the raw materials for tires also include synthetic rubber, steel cord, fiber cord, steel wire, etc. The utility model patent with application number CN201820429809.X (public number: CN208068817U) provides an extrusion device for producing solid tires, including an extruder body, a feed inlet and a feed hopper. The feed hopper is provided with a fixed rod A and a fixed rod B. A stirring device A is provided on the fixed rod A, and a stirring device B is provided directly below the stirring device A. The stirring device B is located on the fixed rod B. The positions of the stirring device B and the stirring device A are corresponding, and both the stirring device A and the stirring device B are connected to the same driving device. By setting the stirring device A and the stirring device B in the feed hopper for stirring, the stirring and extrusion effect is good. The aforementioned patent involves directly feeding materials into the hopper, which may result in excessively high local material concentrations or accumulation due to rapid feeding, making it impossible to mix the materials evenly. Utility Model Content

[0003] In view of this, the present invention provides a raw material preparation device for rubber tires, which solves the technical problem that when materials are directly fed into the hopper, the local material concentration may be too high or the material may accumulate due to the feeding speed, making it impossible to mix the materials evenly.

[0004] This utility model is implemented as follows: This utility model provides a raw material preparation device for rubber tires, which has a feeding hopper, wherein a mixing barrel is provided at the lower end of the feeding hopper, and a conveying pipe is fixedly installed in the middle of the bottom wall of the mixing barrel. The mixing barrel is rotatably connected to the support frame through the conveying pipe. The feed hopper, the mixing tank, and the conveying pipe are internally connected, and a feeding adjustment component is installed inside the feed hopper.

[0005] Based on the above technical solution, the raw material preparation device for rubber tires of this utility model can be further improved as follows: Furthermore, the feeding adjustment component includes a support plate, the support plate having a vertically penetrating through hole A in the middle, a circular plate being fixedly installed inside the through hole A, and a plurality of feeding ports arranged in a circumferential array on the circular plate.

[0006] Furthermore, an adjustment plate is provided above the circular plate and is rotatably connected to the through hole A. The adjustment plate has an adjustment port that is consistent with the discharge port.

[0007] Furthermore, the mixing tank is equipped with a rotating rod that rotates in place. The top end of the rotating rod passes through the circular plate and is fixedly connected to the middle of the adjusting plate. Multiple symmetrically arranged stirring blades are fixedly installed on the rotating rod.

[0008] Furthermore, a through hole B is provided in the middle of the top plate of the support frame, and the conveying pipe is rotatably connected in the through hole B. A roller is rotatably connected to the outer edge of the bottom wall of the mixing tank.

[0009] Furthermore, a gear ring is fixedly installed on the outer circumferential surface of the mixing tank, and a spur gear is meshed with the lower end of the gear ring. The spur gear is rotatably connected to the vertical plate.

[0010] Compared with the prior art, the beneficial effects of the raw material preparation device for rubber tires provided by this utility model are: By setting the stirring blades and the mixing tank to rotate in opposite directions, the raw materials in the mixing tank are uniformly mixed and stirred. By setting the rotating rod to be driven by a motor outside the mixing tank, the weight of the mixing tank is reduced, and excessive force is avoided during the rotation process; By adjusting the rotation of the regulating port relative to the discharge port, the degree of leakage from the discharge port can be adjusted to avoid excessive discharge. By setting up the feeding component, the material can be fed slowly under the rotation of the regulating plate, so that the raw materials gradually enter the mixing area, avoiding the impact load on the mixing blades caused by a large amount of material at once, and making the material evenly distributed in the mixing tank. By setting up a rotating rod and an adjusting plate, the linkage between the adjusting port and the stirring blade is adjusted through a drive device; Attached Figure Description

[0021] Optionally, in the above technical solution, the mixing tank 3 is provided with a rotating rod 31 that rotates in place. The top end of the rotating rod 31 passes through the circular plate 21 and is fixedly connected to the middle of the adjusting plate 23. Multiple symmetrically arranged stirring blades 32 are fixedly installed on the rotating rod 31.

[0022] Optionally, in the above technical solution, a through hole B40 is provided in the middle of the top plate of the support frame 4, and a conveying pipe 30 is rotatably connected in the through hole B40. A roller 34 is rotatably connected at the outer edge of the bottom wall of the mixing tank 3.

[0023] Optionally, in the above technical solution, a gear ring 41 is fixedly installed on the outer peripheral surface of the mixing tank 3, and a spur gear 42 is meshed with the lower end of the gear ring 41. The spur gear 42 is rotatably connected to the vertical plate 43.

[0024] The conveying pipe 30 is rotatably connected to the through hole B40 via a bearing. The conveying pipe 30 extends out of the bottom wall of the top plate of the support frame 4 and is located directly above the feed inlet of the extruder.

[0025] Preferably, a solenoid valve is installed inside the conveying pipe 30. After the raw materials are stirred by the stirring blades 32, the solenoid valve is opened to allow the mixed raw materials to be discharged through the conveying pipe 30.

[0026] Furthermore, a bracket 5 is fixedly installed on the left end of the support frame 4. The top plate of the bracket 5 is located directly above the feed hopper 1. The output shaft of the motor A51 is installed on the bottom wall of the top plate of the bracket 5 through the motor base, extending downward and connected to the top end of the connecting rod A52. The bottom end of the connecting rod A52 is fixedly installed on the adjusting plate 23. The connecting rod A52, the adjusting plate 23, and the rotating rod 31 are collinear.

[0027] Furthermore, a pad is fixedly installed on the right end of the support frame 4, and a motor B44 is fixedly installed on the pad via a motor mount. The output shaft of the motor B44 extends to the left and its end is connected to the right end of the connecting rod B45. The left end of the connecting rod B45 is fixedly connected to the spur gear 42. The connecting rod B45 is rotatably connected to the vertical plate 43 via a bearing.

[0028] Working principle: The starting motor A51 drives the adjusting plate 23 to rotate in place via the connecting rod A52. Raw materials are added through the feed inlet at the top of the feed hopper 1. During the rotation of the adjusting plate 23, the adjusting port 24 rotates in place, changing from being aligned with the discharge port 22 on the fixed circular plate 21 to being staggered (when aligned, the discharge port 22 and the adjusting port 24 correspond one-to-one, and the discharge is at its maximum). Figure 5 When the plates are misaligned, the discharge port 22 and the adjustment port 24 are displaced, meaning the adjustment port 24 is located on the plane of the circular plate 21. In this case, the discharge port 22 is blocked and material cannot be discharged. Figure 6 During the transition to the staggered process, the adjusting plate 23 gradually covers the circular plate 21, that is, the portion exposed at the discharge port 22 gradually decreases, and the discharge rate also gradually decreases, such as... Figure 7-8 This process is repeated to control the amount of raw materials entering the mixing tank 3, which can disperse the feeding, prevent impact on the mixing blades 32, prevent excessive raw materials from piling up, and make the mixing more uniform. During the rotation of the regulating plate 23, the rotating rod 31 drives the stirring blade 32 to rotate clockwise, stirring and mixing the raw materials falling into the mixing tank 3. The motor B44 is started, which drives the spur gear 42 to rotate in place through the connecting rod B45. The spur gear 42 drives the gear ring 41 that meshes with it to rotate in place around the vertical central axis of the gear ring 41, thereby driving the mixing tank 3 to rotate in place (the mixing tank 3 rotates counterclockwise). The raw materials are mixed evenly. Once the mixing is complete, the preparation process of the tire raw materials is finished. (Open the solenoid valve) and let it enter the extruder.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
