Description

A dust-absorbing grinding device for a dust-free stone carving grinding system

This invention is a divisional application of the invention patent "a dust-free stone carving grinding system". The original application date is June 19, 2014. The original application number is 2014102743757. A dust-free stone carving grinding system".

technical field

The invention relates to the field of stone carving grinding, in particular to a dust-free stone carving grinding system with a dust removal function machine and an enhanced motor cooling function.

Background technique

Jade, jade, crystal, agate, tianhuangshi, bloodstone and other high-end stone ornaments, handles, handicraft decorations, etc. have been high-end consumer goods and collectibles since ancient times. In the field of stone carving technology, with the development of technology and technology, mechanical carving has replaced the original manual carving, and mechanical carving uses mechanical grinding as the main processing technology.

Existing mechanical engraving equipment is mainly based on hanging grinding equipment. The hanging grinding equipment is a mechanical equipment that uses a motor as a power source, transmits power with a flexible shaft, and cuts stone with a grinding tool rotating at a high speed. Hanging grinding is mainly responsible for coarse grinding, fine grinding, drilling, grinding, polishing and other processes.

Although the amount of dust generated by mechanical grinding is not much when operating the hanging mill for processing, the dust particles are fine and easily fly in the air, causing great harm to the body of the operator.

A solution in the prior art is that the operator generally removes dust from the dripping part of the stone surface. Although this method reduces part of the dust, it has the disadvantage of mud splashing caused by grinding tools. At the same time, the hands of the operator must be Long-term contact with water will cause the skin of the hand to swell, affect the touch of the hand, and reduce the accuracy of the operation. In severe cases, the skin of the hand will induce dermatitis; when the operator operates in winter, the hand will be in contact with low-temperature water for a long time, which will further affect the processing. precision. Even if the operator adopts the method of dripping water to remove dust, when the operator operates for a long time, part of the dust splashed from the side will still cause respiratory discomfort.

Another solution in the prior art is to install an additional set of dust collectors in addition to the hanging and grinding equipment, and the additional dust collectors can perform large-scale dust removal on the entire operation surface, so there are high equipment investment costs, high power consumption, and high noise. , In winter, the operator's hands are cold and other disadvantages.

The motor of the hanging mill generates heat during use. Although there are fan blades at the rear end of the motor, the fan rotates with the motor shaft to generate wind to dissipate heat. The heat dissipation mode of this motor has the defect that the wind blows out in all directions and is not concentrated on the surface of the motor, which is not conducive to the rapid heat dissipation of the motor.
