Technical Field

The invention relates to the field of stone polishing instruments, in particular to a noise reduction stone polisher.

Background

The DIY polishing is carried out on agate, jade or other stones with strange and different shapes, and the DIY polishing is gradually popular in China in recent years and becomes a preference for time spent at home by not less people; a stone grinding enthusiast usually adopts a small stone grinding machine to grind stones at home, and stones and abrasive materials to be ground are added into the stone grinding machine, so that the stones and the abrasive materials are continuously rubbed when the stone grinding machine rotates or rolls, and grinding and polishing of the stones are realized; the stone polisher is used for polishing stones, and compared with manual polishing, the efficiency is doubled; the existing small stone polisher generally comprises a roller and a roller, wherein the roller is driven to rotate when rotating, so that the aim of polishing stones is achieved, but the roller and the roller are in hard contact, and the roller can vibrate or collide when rotating, so that the polisher has large noise when rotating.

Disclosure of Invention

In order to solve the problem of high noise of the conventional stone grinding machine, the invention provides a noise-reducing stone grinding machine which comprises a double-layer damping barrel and a rotary driving mechanism for driving the double-layer damping barrel to rotate; the double-layer damping barrel is connected with the rotary driving mechanism; the double-layer damping barrel comprises a barrel body and a damping layer arranged on the outer layer of the barrel body.

Furthermore, the shock absorption layer comprises a plurality of buffer ribs; the buffering ribs are used for reducing vibration of the drum body.

Furthermore, the buffering ribs are made of rubber materials.

Further, the rotary driving mechanism comprises a motor and a roller; the rolling shaft is connected with a rotating shaft of the motor through a transmission belt.

Furthermore, the outer surface of the roller is provided with a damping material.

Further, the damping material is PU soft rubber.

Further, still include the sound-proof housing, the sound-proof housing covers to be located double-deck shock attenuation bucket and the rotary drive mechanism is outside.

According to the noise-reducing stone polisher, the damping layer is arranged outside the roller body, when the double-layer damping barrel rotates, the damping layer plays a role in buffering and damping the roller body, and vibration generated by the double-layer damping barrel is greatly weakened through the damping layer, so that noise generated by the double-layer damping barrel during rotation is reduced, noise is reduced from a noise source, the stone polisher is quiet during operation, and the noise reducing function is achieved.
