A fully automatic sandblasting device

Abstract

The invention relates to the technical field of workpiece sand blasting, in particular to a full-automatic sand blasting device. The full-automatic sand blasting device comprises a machine frame, a sand blasting chamber, a conveying mechanism, a sand supply mechanism and a sand blasting mechanism, wherein the sand blasting chamber, the conveying mechanism, the sand supply mechanism and the sand blasting mechanism are arranged on the machine frame; the conveying mechanism penetrates through the sand blasting chamber; the sand blasting mechanism comprises a driving assembly arranged on the machine frame, and a spray gun arranged at the tail end of the driving assembly; the sand supply mechanism comprises a sand pump, a sand stirring assembly and a sand conveying assembly; during actual use,outside workpieces are conveyed automatically by the conveying mechanism, sandy water pumped by the sand pump passes through the sand stirring assembly and the sand conveying assembly and then is sprayed out through the spray gun, the spray gun is driven by a driving mechanism to move back and forth so as to spray the sandy water sprayed by the spray gun to the workpieces, thus, automatic sand blasting treatment of the workpieces is achieved, and the workpiece sand blasting efficiency is improved; and sandy water flowing through the sand stirring assembly is sprayed into the sand blasting chamber through sand outlets of the sand stirring assembly to stir sandy water in the sand blasting chamber, the situation that sandy water settled in the sand blasting chamber is pumped by the sand pumpand sprayed out, and consequently the sand blasting effect of the workpieces is poor is avoided, and the sand blasting yield of the workpieces is increased.

Description

Technical field [0001] The invention relates to the technical field of workpiece sandblasting, and in particular discloses a fully automatic sandblasting device. Background technique [0002] In the manufacturing process of the workpiece, in order to increase the corrosion resistance of the workpiece, spraying treatment is often required. Before the spraying treatment of the workpiece, the workpiece needs to be sandblasted to improve the surface roughness of the workpiece, thereby increasing the workpiece and the coating. The adhesion between. [0003] In the process of sandblasting, the prior art mainly involves the operator first manually moving the workpiece to be sandblasted to the station to be sandblasted, and then the operator holds the sandblasting gun to perform sandblasting on the workpiece. The blasting efficiency of the workpiece is low. [0004] In addition, in order to realize the recycling of sand water, the sand water sprayed by the sand blasting gun will automatica...

[0003] In the process of sand blasting, the prior art mainly moves the workpiece to be sand blasted manually to the station to be sand blasted by the operator, and then the operator holds the sandblasting gun to perform sandblasting on the workpiece. Inefficient blasting of workpieces

[0004] In addition, in order to realize the recycling of sand and water, the sand and water ejected from the sand blasting gun will automatically flow into the sand holding tank of the sand blasting machine under the action of gravity, and the power pump will pump the sand and water in the sand holding tank to pass through the sand blasting machine again. But the sand water settles in the sand holding tank, that is, the sand material in the sand water will drop to the lower part of the sand holding tank, and the water in the sand water will rise to the upper part of the sand holding tank. At this time, the sand water pumped by the power pump If the concentration changes greatly, it will be sprayed onto the workpiece through the sandblasting gun again, which will cause poor sandblasting of the workpiece.
