Pressure-sensing type sandblasting gun and sandblasting machine thereof

Abstract

The invention discloses a pressure-sensing type sandblasting gun and a sandblasting machine thereof. The pressure-sensing type sandblasting gun and the sandblasting machine thereof comprises a sandblasting gun barrel and a pressure tank, a funnel-shaped sealing head is arranged at the lower end of the interior of the pressure tank, an air pressure valve is arranged at the lowest end of the centerof the sealing head, one side of the air pressure valve is connected with an output opening of the bottom end of a high-pressure air pump through an air tube, and an exhaust opening of the other end of the air pressure valve is connected with a sand conveying tube; the sandblasting gun barrel is arranged at the tail end of the sand conveying tube, a pressure sensing platform is arranged on the upper end face of the sandblasting gun barrel in a protruding mode, and a sensing cushion layer is arranged at the upper end of the pressure sensing platform; and a pressure sensitive sensor is mounted in the pressure sensing platform and is tightly attached to the lower end of the sensing cushion layer, a control module is arranged in an electric control cabinet, the control module is connected withthe pressure sensitive sensor, and a safety valve is arranged at the connecting place of the sandblasting gun barrel and the sand conveying tube. In this way, the pressure-sensing type sandblasting gun and the sandblasting machine thereof can control the size of the air pressure value of jetting of the sandblasting gun according to the pressure degree.

Description

Technical field [0001] The invention relates to the field of sandblasting machines, in particular to a pressure-sensitive sandblasting gun and a sandblasting machine. Background technique [0002] The sandblasting machine uses compressed air to transport powdery granular materials from one place to another, and a large amount of abrasives such as quartz sand and compressed air are ejected from the nozzle together. During the process of transforming kinetic energy into potential energy, it moves at a high speed. The sand blasting machine is inseparable from the processing of parts. The current sand blasting machine is developing rapidly. Excluding the old type sand blasting machine, there are many advanced electrical equipment such as CNC sand blasting machines. The equipment has also been developed and put into use. However, for general sandblasting requirements and considering cost and other factors, the improved solution for simple traditional sandblasting machines has more mar...

Problems solved by technology

[0002] The sandblasting machine uses compressed air to transport powdery granular materials from one place to another, and sprays a large amount of abrasives such as quartz sand and compressed air out of the nozzle together. In the process of converting kinetic energy into potential energy, the high-speed movement The sand scouring the surface of the object can improve the surface quality of the object. The sandblasting machine is inseparable from the processing of the parts. The current sandblasting machine is developing rapidly.
