Sand blasting machine

Abstract

The invention discloses a sand blasting machine, which comprises a sand blasting chamber. The sand blasting chamber comprises a feeding hole for feeding and discharging workpieces, and spray nozzles arranged in the sand blasting chamber; the spray nozzles are fixed on a spray nozzle drive mechanism; a feeding mechanism capable of driving the workpieces to feed and discharge is matched on the feeding hole; the spray nozzle drive mechanism comprises at least one swinging mechanism arranged in the sand blasting chamber; each swinging mechanism is provided with one spray nozzle and is driven by a first drive part to swing to the left and right; the feeding mechanism comprises a placement platform used for placing workpieces and a second drive part; and the placement platform comprises at least one positioning table used for placing the workpieces, and a sealing plate arranged behind the positioning table and matched with the feeding hole of the sand blasting chamber. A plurality of swinging mechanisms are arranged in the sand blasting chamber, and a plurality of spray nozzles can swing to blast sand on the workpieces when being used for blasting sand, so that a uniform and efficient sand blasting effect is realized; and in addition, the workpieces can be quickly fed and discharged in the sand blasting chamber through the feeding mechanism, so that the sand blasting efficiency of the workpieces is further improved.

Description

technical field [0001] The invention relates to the field of painting equipment, more specifically, it relates to a sandblasting machine. Background technique [0002] Sand blasting uses compressed air as the power to form a high-speed jet beam to spray materials: copper ore, quartz sand, corundum, iron sand, Hainan sand, etc., to the surface of the workpiece to be treated at high speed, so that the outer surface of the workpiece surface looks smoother. or change in shape. Due to the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of the workpiece can obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece can be improved, the fatigue resistance of the workpiece can be improved, and the gap between the workpiece and the coating can be increased. Excellent adhesion, prolonging the durability of the coating film, and also conducive to the leveling and decoration of...

Problems solved by technology

[0004] However, in the prior art, when sandblasting large-scale workpieces such as wheel hubs, most of them manually enter the blasting chamber for sandblasting, and a single blasting head is used for sandblasting. When the workpiece is sandblasting, most of the workpieces are manually entered into the sandblasting room to pick and place the workpiece. Not only is it difficult to control the accuracy of the workpiece placement, but the efficiency of picking and placing the workpiece is also very low.
