Abstract

The invention relates to the field of valves and discloses an air channel switch valve and a grinding machine. The air channel switch valve comprises a seat body, a switch structure and a driving mechanism. A vent hole is formed in the seat body, the switch structure comprises a frame body arranged on the seat body and a plurality of gate plates arranged in the frame body, the frame body is arranged along the edge of an opening in one end of the vent hole, and an airflow passage is defined by the frame body and the vent hole jointly. A plurality of mounting holes are formed in the peripheral side of the frame body, each gate plate is rotationally connected with the corresponding mounting hole through a shaft body, the shaft bodies partially extend out of the frame body, when the multiple gate plates are turned over, the airflow passage in the frame body can be opened or closed selectively. The driving mechanism is used for driving all the gate plates to rotate relative to the frame body. The grinding machine comprises the air channel switch valve. The driving mechanism drives the gate plates to be turned over to achieve opening or closing of the airflow passage, the structure is simple and stable, operation is convenient, the open degree of the air channel switch valve can be controlled through the rotating angle, and thus the air flow rate is controlled.

Description

technical field [0001] The invention relates to the field of valves, in particular to an air circuit switching valve and a grinding machine. Background technique [0002] With the continuous development of electronic technology, more and more TFT-LCD (Thin Film Transistor-Liquid Crystal Display, liquid crystal display) are widely used in various electronic products, TFT-LCD display is usually made of TFT-LCD glass substrate manufacture. [0003] The post-processing production process of TFT-LCD (liquid crystal display) glass substrate is mainly the grinding of edges and chamfers. A grinder is a grinder that grinds the surface of a workpiece with a grinding tool coated or embedded with abrasives. It is mainly used for grinding high-precision planes, inner and outer cylindrical surfaces, conical surfaces, spherical surfaces, threaded surfaces and other profiles in the workpiece. The main types of grinders are disc grinders, shaft grinders and various special grinders. The ...
