Cooling water nozzle and glass washer

Abstract

The invention relates to the technical field of machinery, in particular to a cooling water nozzle and a glass washer. The cooling water nozzle is used for spraying cooling water onto a grinding wheeland comprises a main body and a connection seat. The main body is provided with a first arc surface and a water spray opening, the water spray opening is arranged in the first arc surface, and the first arc surface is arranged to be close to the periphery of the grinding wheel; the connection seat is connected with the main body, and the water spray opening extends to the connection seat; and theconnection seat is arranged to be connected with a source water way. Through the cooling water nozzle, the influence of airflow generated during grinding wheel rotation on cooling water spraying is reduced, it is ensured that the cooling water can be sufficiently sprayed onto the surface of the grinding wheel, accordingly, the edge grinding effect of the grinding wheel on glass is ensured, and the precision of a glass panel is guaranteed.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular, to a cooling water nozzle and a glass washing machine. Background technique [0002] Generally, in glass manufacturing, especially in the manufacture of liquid crystal panels, grinding the glass is an important step to ensure the quality of the glass. The grinding of glass is achieved by contacting the grinding wheel with the glass surface. When grinding the grinding wheel, it is necessary to spray cooling water on the surface of the grinding wheel to ensure the quality of the glass surface. [0003] With the rotation of the grinding wheel, a certain air flow will be formed outside the grinding wheel, and the air flow will increase with the increase of the rotation speed of the grinding wheel. When the grinding cooling water is sprayed on the grinding wheel, the cooling water will not be completely sprayed due to the air flow. It is poured into the grinding wheel groove, which ...

AI Technical Summary

Problems solved by technology

[0003] With the rotation of the grinding wheel, a certain air flow will be formed outside the grinding wheel, and the air flow rate will increase with the increase of the grinding wheel speed. When the grinding cooling water is sprayed on the grinding wheel, the cooling water will not be sprayed completely due to the air flow. Sprinkled into the grinding wheel groove, resulting in a decrease in the actual utilization of cooling water

[0004] The substrate glass is a high-precision processing product. Due to insufficient cooling water for grinding, it may lead to poor quality of edging and cause users to stop casting.

At the same time, due to insufficient cooling water, the loss of the grinding wheel will increase, and the frequency of repairs will increase, which will eventually lead to a decrease in the life of the grinding wheel

[0005] At present, linear nozzles are generally used in this field to reduce the influence of the air flow on the grinding cooling water when the grinding wheel rotates at a high speed with high pressure and large flow rate. However, this method consumes a lot of water and requires more energy, so the economic benefit is not good.
