A spray gun structure of an automatic sandblasting machine

Abstract

The invention discloses a blasting gun structure of an automatic sand blasting machine. The blasting gun structure comprises an upper plate, a lower plate, a main pipe, a sand blasting head and a promoting pipe, wherein the upper plate and the lower plate are connected through guiding columns; lower ends of the guiding columns are fixedly connected with the lower plate; upper ends of the guiding columns penetrate through the upper plate, and limiting portions are arranged at the upper portion of the upper plate; springs are arranged on the guiding columns between the upper plate and the lower plate; the lower portion of the main pipe is connected and fixed with the lower plate, the upper portion of the main pipe is sleeved with the upper plate in a sliding mode, and a sand inlet is formed in the outer side of the middle portion of the main pipe; the sand blasting head is connected and fixed with the lower end of the main pipe; and the lower end of the promoting pipe is connected and fixed with the upper end of the main pipe, a locator transmitter is arranged at the upper end of the promoting pipe, and a speed increasing air inlet is formed in the side wall of the promoting pipe. According to the blasting gun structure, automatic sand blasting can be achieved; positioning of sand blasting is accurate; obtained sand layers are high in uniformity, and filming is not required; 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 a spray gun structure of 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. Theref...

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.
