Description

The present invention takes up the field of rough surface processing technology, and specifically, is an eco-type sandblasting machine for roughening a product.

At this time, in order to add properties such as adhesiveness and roughness to the product, it is necessary to roughen the product by rough surface processing technology. The most widely used technique is sandblasting, that is, a processing method in which an abrasive such as metal or ceramic grains is sprayed onto the product surface at high speed. However, this processing method is very non-eco-friendly, dust drifts in the workplace, threatens the safety of employees, and waste powder after spraying is difficult to collect and easily causes environmental pollution. In addition, when manually sandblasting during creation, it is difficult to match the spray angle and altitude, the effect of sandblasting becomes non-uniform, and also if the product is simply placed and not moved. It resonates with the effect of sandblasting.
