Pneumatic sliding block device for flat air grid

Abstract

The utility model discloses a pneumatic sliding block device for a flat air grid. The pneumatic sliding block device comprises an air cylinder and a sliding block, the sliding blocks are tightly attached to the inner wall faces, provided with the air outlet holes, of the air grid bars, and the sliding blocks extend in the length direction of the air grid bars; the sliding block is provided with a plurality of through holes arranged at intervals in the length direction, and the through holes are used for being aligned with or staggered from the corresponding air outlet holes. The length of the sliding blocks is smaller than that of the air grid bars, and the sliding blocks located on the upper air grid set and the sliding blocks located on the lower air grid set are arranged in a one-to-one up-and-down corresponding mode. One end of the sliding block penetrates through one end of the air grid bar to be connected with the output end of the air cylinder. The air cylinder drives the sliding block to move in the air grid bar. The air outlet area of the flat air grid can be adjusted, so that the production requirements of quenching and tempering glass with different transverse widths are met, the cooling efficiency of the flat air grid is improved, and the energy consumption is reduced.
