Conveying type automatic sand-blasting machine

Abstract

The invention relates to the technical field of sand blasting, in particular to a conveying type automatic sand-blasting machine. The conveying type automatic sand-blasting machine comprises a sand-blasting mechanism and an impurity removing mechanism communicating to the sand-blasting mechanism. The sand-blasting mechanism comprises a sand-blasting rack, a sand-blasting chamber arranged in the sand-blasting rack, a conveying device arranged on the sand-blasting rack for inputting a workpiece in the sand-blasting chamber and outputting the workpiece out of the sand-blasting chamber, a spray gun device movably arranged in the sand-blasting chamber for blasting sand to the workpiece conveyed by the conveying device, an air pressure supply device for providing an air pressure to the spray gundevice, a sand material recovering device for recovering a sand material sprayed by the spray gun device and a sand extraction device arranged on the sand-blasting rack and communicating to the sandmaterial recovering device. The impurity removing mechanism communicates to the sand extraction device. The conveying type automatic sand-blasting machine can improve the degree of automation, improves the conveying efficiency of the workpiece, is good in separating effect and good in dust collecting effect, improves the sand grain recovery utilization ratio and lowers the processing cost.

Description

technical field [0001] The invention relates to the technical field of sandblasting, in particular to a conveying type automatic sandblasting machine. Background technique [0002] The sandblasting machine uses compressed air as the power to form a high-speed jet beam to spray the spray material (steel sand, quartz sand, corundum, glass sand, resin sand, etc.) change. Due to the impact and cutting effect of the spray on the surface of the workpiece, the surface of the workpiece can obtain a certain degree of cleanliness and different roughness, and the mechanical properties of the surface of the workpiece are improved, so the fatigue resistance of the workpiece is improved, and the surface and coating of the workpiece are increased. The adhesion between layers prolongs the durability of the coating film, and is also conducive to the leveling and decoration of the coating. Sand blasting can remove impurities, variegated colors and oxide layers on the surface of the workpiece...

AI Technical Summary

Problems solved by technology

[0003] However, the traditional sandblasting machine has low efficiency and low degree of automation in conveying workpieces. During the sandblasting process, workpiece debris and a large amount of dust will be generated. The dust is easy to pollute the air, and the sand can be recycled. The traditional sandblasting equipment The dust removal effect is poor, and the separation effect on the mixture of dust, workpiece debris and sand is poor, the recycling rate of sand particles is low, and the processing cost is high
