Description

Pellet manufacturing device with a rotary speed reducer for detachable pellet die The present invention relates to a pellet manufacturing apparatus for manufacturing raw materials into pellets. Generally, pellet manufacturing devices produce pellets by extruding raw materials through a pellet die. In order to manufacture pellets in various shapes or sizes according to the raw materials or consumer requirements, the pellet manufacturing device is installed by replacing the pellet dies. The pellet die is connected to the drive unit for rotating the pellet die by a clamp; however, since the clamp is formed of a relatively high-strength metal to support the relatively heavy weight of the pellet die, the clamp is also heavy, which presented a problem in that it was not easy to attach or detach. To solve this problem, a "pellet manufacturing device equipped with a safety clamp assembly for safely attaching and detaching a molding die" was disclosed in the prior art of Korean Registered Patent Publication No. 10-2727978 (November 5, 2024). The aforementioned conventional pellet manufacturing device could easily detach the pellet die by separating the clamp from the pellet die without completely separating the clamp for fixing the pellet die through a safety clamp assembly. However, conventional pellet manufacturing devices have multiple clamps attached around the perimeter of the pellet die by individual bolts, requiring all bolts to be loosened to detach the pellet die. Since the pellet die is heavy and cannot be easily rotated due to its engagement with the drive system, operators must rotate to dismantle the bolts, which not only requires a large number of personnel but also results in a long time required for the detachment of the pellet die.
