Description
Technical Field
[0001] The utility model relates to the technical field of abrasive granulation, and more specifically, it relates to an abrasive granulator. Background Art
[0002] In the existing technology, an abrasive granulator is a commonly used industrial equipment, which realizes the crushing and granulation of abrasives through the drive of a motor during the production process. However, there is a technical problem in the use of this equipment: when the force of the abrasive is too large and exceeds the bearing range of the motor, due to the lack of an effective anti-overload device, the motor may be damaged. This situation not only affects the normal operation of the abrasive granulator, but also may bring additional maintenance costs and production delays.

This kind of damage will not only reduce the use effect of the equipment, but also may have a negative impact on the stability and production efficiency of the entire production line. In addition, the damage of the motor may lead to expensive maintenance costs and a long downtime, further increasing the operating costs of the enterprise. Summary of the Invention

[0013] Compared with the prior art, the present utility model provides an abrasive granulator, which has the following beneficial effects:
[0014] 1.

The design of the discharge holes on the bottom plate ensures that the abrasives can be smoothly discharged after reaching a certain particle size, thus completing the granulation process. The rotating mechanism with this structure not only improves the processing efficiency of the abrasives but also ensures the consistency of the granulation quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In this embodiment, when the transmission is carried out by the motor 2, first, the transmission shaft 3 is stuck on a plurality of clamping blocks 15, and the clamping force applied by a plurality of springs 14 ensures the connection between the transmission shaft 3 and the fixed sleeve 4. Then, a plurality of tension springs 16 ensure the stability between the plurality of clamping blocks 15. When the transmission force exceeds the clamping force of the plurality of springs 14, the connection will be released, so that the motor 2 is in an idling state, thus avoiding the damage of the motor 2. When it is necessary to adjust the clamping force, the rotation of the threaded tube 17 can drive the slider 13 to slide along the shrinkage sleeve 12.

[0030] More specifically, when abrasive granulation is carried out, since the raw materials are placed in the housing 23, abrasives are made through the rotation between the bottom disk 24 and the receiving roller 26. When the raw materials meet the diameter of the discharge holes 27, they will leak out, thus completing the granulation process.
[0031] In summary, when the overall equipment is in use or operation: When the transmission is carried out by the motor 2, first, the transmission shaft 3 is stuck on a plurality of clamping blocks 15, and the clamping force applied by a plurality of springs 14 ensures the connection between the transmission shaft 3 and the fixed sleeve 4. Then, a plurality of tension springs 16 ensure the stability between the plurality of clamping blocks 15. When the transmission force exceeds the clamping force of the plurality of springs 14, the connection will be released, so that the motor 2 is in an idling state, thus avoiding the damage of the motor 2. When it is necessary to adjust the clamping force, the rotation of the threaded tube 17 can drive the slider 13 to slide along the shrinkage sleeve 12. By changing the position of the slider 13, the distance between the plurality of clamping blocks 15 is changed, and thus the clamping force is changed. When the adjustment is completed, the follower sleeve 8 is inserted into the insertion rod 10. Then, since the follower sleeve 8 is slidably connected to the vertical bar 9, the extension disk 5 is fixed. Then, the fixing of the follower sleeve 8 is ensured under the action of the push spring 7, and thus the adjustment process is completed.
[0032] When abrasive granulation is carried out, since the raw materials are placed in the outer shell 23, the abrasives are made through the rotation between the bottom plate 24 and the receiving roller 26. When the raw materials meet the diameter of the discharge hole 27, they will leak out, thus completing the granulation process.
