Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a high-efficiency cleaning turntable shot blasting machine. Background Art

[0002] Shot blasting machine refers to a casting equipment that uses high-speed projectiles thrown by the shot blaster to clean or strengthen the surface of the casting. The shot blasting machine can simultaneously remove sand, core and clean the casting.

[0003] After searching, a turntable shot blasting machine with the publication number CN220279359U was found. The utility model relates to a turntable shot blasting machine, which belongs to the technical field of shot blasting machines, including a shot blasting machine box, a pulse bag dust collector, a spiral elevator and a workpiece placement frame. The shot blasting machine box and the pulse bag dust collector are connected. In the utility model, the steering motor can drive the turntable and the workpiece on its top to rotate on the top of the load-bearing frame, so as to adjust the shot blasting processing position. The steel shots after shot blasting can pass through the load-bearing frame and fall to the filter screen for screening. Large pieces of workpiece rust can flow on the top of the filter screen. Smaller steel shots can pass through the filter screen and fall to the collection bucket through the return pipe and are transferred to the inner wall of the spiral elevator. The spiral elevator can transfer the steel shots to the shot blasting machine through the feeding pipe for steel shot replenishment. Such a turntable shot blasting machine structure can screen the large pieces of workpiece rust that have been peeled off to prevent them from blocking the steel shot return channel, thereby ensuring processing efficiency.

[0004] At present, shot blasting machines directly place the workpiece to be processed on the processing table, and use the impact force of the falling shot to process the rust and burrs on its surface. However, due to the large impact force when falling during the processing, the workpiece processing frame will be worn due to the impact force and needs to be replaced regularly. The general processing frame or processing table is directly fixed with bolts, which is troublesome to replace. In addition, the shot after processing needs to be manually collected and then added to the shot blasting machine. During the collection process, the shot is easy to fall, resulting in the loss of shot.

[0005] In view of the above problems, we propose an efficient cleaning turntable shot blasting machine. Utility Model Content
