Blowing device used on movable sliding block mechanism of glass substrate detection stress gauge

The invention discloses a blowing device for a glass substrate detection stress gauge moving slider mechanism, which comprises a moving guide rail and a moving slider slidably mounted on the moving guide rail, the moving guide rail is internally provided with a conveying pipeline, and the conveying pipeline is provided with an air inlet at the front end of the moving guide rail. A communicating pipe is installed at the top of the moving guide rail and communicates with the conveying pipeline, two sets of air pipes are installed on the communicating pipe and are arranged in the X-axis direction of the moving guide rail, and mounting grooves matched with the air pipes are formed in the moving sliding blocks; an air channel matched with the air pipe is formed in the movable sliding block, and an air outlet matched with the air channel is formed in the movable sliding block. And dust and glass fragments are prevented from influencing the operation of the movable sliding block, so that the failure rate of equipmen
