[0002] Tires have various excellent properties, such as wear resistance, corrosion resistance, etc. However, when the service life of the tire is exhausted, these advantages become disadvantages. After waste tires are generated, due to the same properties of waste tires, their utilization has become an issue that has to be taken seriously. Recycling waste tires usually includes a series of operations such as cutting the tires, crushing, magnetic separation, fine crushing, grinding, and bagging the rubber powder. Among them, it is necessary to finely crush the waste tires, remove the steel wires and fibers incorporated inside during preparation, and then use a rubber grinder to grind the rubber particles into rubber powder.

[0029] The present invention provides a technical solution:

[0030] Embodiment 1

[0031] Combined with Figures 1 to 4 , a grinding device for waste tire rubber powder includes a main body 3 of the grinding device.

At the same time, the setting of the strong pressure spring 1402 cooperates with the supporting component 13 to limit the position of the screening box 1101, so that when the vibration mechanism 2 starts to vibrate the screening box 1101, the screening box 1101 can be reset after the force application ends, and the vibration of the screening box 1101 is completed in cooperation.

[0035] Embodiment 2

[0036] Refer to Figures 1 to 5 , and on the basis of Embodiment 1, it is further obtained that the vibration mechanism 2 includes a driving component 21, a stabilizing component 22, a transmission component 23 and a limiting component 24. The driving component 21 is arranged on the top of the base 5. The stabilizing component 22 is arranged on the left side of the driving component 21. The transmission component 23 is arranged on the top of the driving component 21. The limiting component 24 is arranged on the outer circle of the transmission component 23.

[0037] The driving assembly 21 includes a driving motor 2101, the driving motor 2101 is fixedly connected to the top of the base 5, a rotating shaft 2102 is fixedly connected to the left side of the driving motor 2101, a cam 2103 is fixedly connected to the outer ring of the rotating shaft 2102, the stabilizing assembly 22 includes a supporting rotating cylinder 2201, the supporting rotating cylinder 2201 is rotatably connected to the left end of the rotating shaft 2102, a fixing rod 2202 is fixedly connected to the bottom of the supporting rotating cylinder 2201, and the fixing rod 2202 is fixedly connected to the top of the base 5. The transmission assembly 23 includes a telescopic plate 2301, the telescopic plate 2301 is arranged on the top of the cam 2103, the bottom of the telescopic plate 2301 is in contact with the top of the outer ring of the cam 2103, a rotating frame 2302 is rotatably connected to the top of the telescopic plate 2301, and the rotating frame 2302 is fixedly connected to the bottom of the screening box 1101. The limiting assembly 24 includes a limiting sleeve frame 2401, the limiting sleeve frame 2401 is slidably connected to the outer ring of the telescopic plate 2301, fixing arms 2402 are fixedly connected to the front and rear sides of the limiting sleeve frame 2401, and the fixing arms 2402 are fixedly connected to the top of the base 5.

[0038] Furthermore: The staff only needs to start the driving motor 2101, then the cam 2103 can be driven to rotate through the rotating shaft 2102. The irregular diameter of the outer ring of the cam 2103 pushes the telescopic plate 2301 upward to complete the pushing of the screening box 1101. In cooperation with the reset component 14 that drives the screening box 1101 to reset, the vibration of the screening box 1101 is completed, so that the crushed materials entering the screening box 1101 can gradually move to the right and pass through the screening plate 1103 to complete the screening.

[0039] During the actual operation process, when this device is in use, the support legs 4 start to crush and grind the waste tires placed inside. The rubber powder materials generated after grinding are discharged through the discharge port 31 and enter the screening box 1101. Then, the driving motor 2101 is started. The driving motor 2101 drives the cam 2103 to rotate through the rotating shaft 2102. The rotation of the cam 2103 drives the left side of the screening box 1101 to swing upward regularly through the telescopic plate 2301. During the process of the cam 2103 rotating and driving the telescopic plate 2301 downward, the left side of the screening box 1101 automatically descends and restores mechanical energy under the action of the strong pressure spring 1402. As the cam 2103 rotates continuously, the screening box 1101 vibrates regularly. The vibration of the screening box 1101 drives the internal screening plate 1103 to vibrate. The vibration of the screening plate 1103 levels and screens the rubber powder materials entering the screening box 1101. The qualified and unqualified materials after screening gradually move to the right under vibration and are discharged through the sieve discharge pipe 1201 and the large particle discharge pipe 1203 respectively to complete the discharging. The qualified rubber powder can be directly processed in the next step, while the unqualified rubber powder raw materials discharged through the large particle discharge pipe 1203 can be re-injected into the support legs 4 for secondary grinding.
