[0002] Sandblasting machine is a cleaning equipment that uses compressed air as power and medium to spray at high speed onto the surface of the workpiece. When the compressed air enters the sandblasting room through the filter, the airflow ejected by the spray gun at high speed will form countless small jets, which are used to sandblast and clean the surface of the workpiece.

[0003] For example, the utility model patent disclosed in the publication number CN220260665U, a fully automatic sandblasting machine includes: a box, a large turntable rotating in the box, a plurality of small turntables circumferentially distributed along the central axis of the large turntable and connected to the large turntable, and a spray gun arranged on one side of the small turntable. In the embodiment of the present application, the purpose of changing the spraying surface of the product is achieved by setting a rotating small turntable by rotating the product, thereby achieving the technical effect of uniform spraying of all sides of the product, thereby solving the technical problem that the back side of the product opposite to the spray gun cannot be uniformly sprayed due to the unchanged angle of the spraying surface of the product.

[0004] Although the above equipment can perform sandblasting cleaning operations on the workpiece, after the workpiece is sandblasted, the workpiece needs to be replaced manually, thereby reducing the efficiency of the equipment in sandblasting multiple groups of workpieces. Therefore, a fully automatic sandblasting machine is urgently needed to solve the above problems. Utility Model Content

[0029] The cross sections of the fixed slider 23 and the limiting rotating seat 72 are both T-shaped, and the fixed slider 23 and the limiting rotating seat 72 are slidably engaged, which can effectively improve the stability of the subsequent limiting rotation between the limiting rotating seat 72 and the fixed slider 23.

[0030] The sandblasting tube 73 is slidably connected to the driven synchronous pulley 6. The sliding connection between the sandblasting tube 73 and the driven synchronous pulley 6 can not only facilitate the subsequent driven synchronous pulley 6 to drive the sandblasting tube 73 to rotate, but also provide sufficient guiding space for the subsequent fixed cylinder 21 to drive the sandblasting tube 73 to lift up.

[0031] The sandblasting drum 71 does not contact the inner wall of the feeding slide plate 9 when rotating in a circle, and the interior of the protective box 8 is hollow, which can effectively improve the noise isolation of the equipment during sandblasting.
