Sand blasting machine with dustproof function

Abstract

The invention relates to a sand blasting machine with a dustproof function. The machine comprises a main body, a workbench, a material box, a material pipe, a spray pipe, a plurality of spray heads, adustproof mechanism and a stirring mechanism, the dustproof mechanism comprises a dustproof cover, a connecting box, a first filter screen, a second filter screen, two air cylinders, two auxiliary assemblies, two air exhaust assemblies and a plurality of suction nozzles, each air exhaust assembly comprises an air exhaust pump, a first connecting pipe and a second connecting pipe, each auxiliary assembly comprises a fixing rod, a fixing plate, an air bag, a first spring, an air inlet pipe and an air outlet pipe, the stirring mechanism comprises a rotating shaft, two torsion springs, two firstbearings, two connecting assemblies and a plurality of stirring plates, and each connecting assembly comprises a connecting rope and a connecting disc. According to the sand blasting machine with thedustproof function, the shielding function is achieved through the dustproof mechanism, the situation that the surrounding air environment is affected due to overflowing of grinding materials is avoided, therefore the environmental protection property of the machine is improved, the stirring function is achieved through the stirring mechanism, the grinding materials in the material box are mixed evenly, and the sand blasting quality is improved.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a sandblasting machine with dustproof function. Background technique [0002] Sand blasting machine is a process of cleaning and roughening the surface of the substrate by the impact of high-speed sand flow. Compressed air is used as the power to form a high-speed jet beam to spray the spray material to the surface of the workpiece to be processed at high speed, so that the appearance or shape of the outer surface of the workpiece surface changes. Due to the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of the workpiece The surface has a certain degree of cleanliness and different roughness, which improves the mechanical properties of the workpiece surface, thus improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, and prolonging the durability of the coating film. It is also beneficial to the l...
