In the process of converting kinetic energy into potential energy, the high-speed moving sand particles scour the surface of the object to improve the surface quality of the object. Due to the impact and cutting action of the abrasive on the workpiece surface, the sandblasting machine makes the surface of the workpiece obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the workpiece surface are improved.

The position of the positioning rod allows the two positioning rods to enter the inside of the two positioning holes. At this time, the filter plate also completely enters the inside of the sandblasting machine body. After the abrasive enters the inside of the sandblasting machine body, the rotation of the two gears will drive the two rotating shafts and the two abrasive rollers to rotate, thereby realizing the grinding of the abrasive.

[0011] Preferably, a feed hopper is connected to the top of the sandblasting machine body, and abrasive can be added into the interior of the sandblasting machine body through the feed hopper.
[0012] In summary, this application includes the following beneficial technical effects:
[0013] 1. Start the servo motor and add abrasive into the inside of the sandblasting machine body through the feed hopper. After the abrasive enters the inside of the sandblasting machine body, the cooperation of the servo motor, the rotating shaft and the two gears will drive the two grinding rollers to rotate in opposite directions, thereby grinding the abrasive.

[0014] 2. Start the forward and reverse motors. The forward and reverse motors will drive the cross bar to rotate. The rotation of the cross bar will drive the ellipsoid block to rotate. The rotation of the ellipsoid block will squeeze the filter plate and the damping rod. The damping rod will continuously expand and contract, thereby driving the filter plate to vibrate back and forth, thereby avoiding clogging of the filter plate due to excessive abrasives and increasing the filtering effect of the filter plate.
[0015] 3. The L-shaped plate can be pulled out of the sandblasting machine body by pulling the vertical plate, so that the larger particles of abrasive on the surface of the filter plate can be collected and re-grinded, thereby increasing the grinding effect. BRIEF DESCRIPTION OF THE DRAWINGS
