Automatic sand blasting machine

Abstract

The invention discloses an automatic sand blasting machine which comprises a rack, a sand supply system, a sand blasting system and a control system. A transverse guide rail is arranged on the rack in a length direction of the rack, and a transverse sliding table is in sliding connection with the transverse guide rail, and the transverse sliding table is driven by a transverse driving system to slide on the transverse guide rail. A positioning plate for positioning a substrate to be blasted with sand is arranged on a tabletop of the transverse sliding table. A longitudinal guide rail is erected above the positioning plate. A longitudinal sliding table is in sliding connection with the longitudinal guide rail, and the longitudinal sliding table is driven by a longitudinal driving system to slide on the longitudinal guide rail. The sand blasting system is arranged at the side, facing the positioning plate, of the longitudinal sliding table. The sand blasting system is constituted by at least one spray gun, and the sand blasting system provides the spray gun with sand for sand blasting. The sand blasting machine in the invention achieves automatic sand blasting by means of a numerical control technology, and is accurate in sand blasting positioning; the obtained sand layer is high in uniformity with no need of sticking a film; therefore, the production efficiency is greatly improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of sandblasting, in particular to an automatic sandblasting machine. Background technique [0002] Sand blasting is a process that uses high-speed airflow to spray sand particles and attach them to the surface of glass, stone and other substrates to form a patterned sand layer. The existing sandblasting generally adopts the manual sandblasting method. First, a layer of film is pasted on the surface of the substrate to be sandblasted, and then the film on the place to be sandblasted is torn off, and then the spray gun is manually aimed at the place to be sandblasted. , When the sandblasting is finished, the film is torn off, and the above-mentioned method of pasting the film for sandblasting is not only low in production efficiency and large in material loss, but also the thickness of the sand layer obtained by manual sandblasting is difficult to achieve consistency and poor uniformity. Therefore, there is an urgent n...

Problems solved by technology

The existing sandblasting generally adopts the manual sandblasting method. First, a layer of film is pasted on the surface of the substrate to be sandblasted, and then the film on the place to be sandblasted is torn off, and then the spray gun is manually aimed at the place to be sandblasted. , when the sandblasting is over, the film is torn off. Sandblasting with the above film method not only has low production efficiency and large material loss, but also the thickness of the sand layer obtained by manual sandblasting is difficult to achieve consistency and poor uniformity.
