Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting machines, in particular to an improved dust collection system for a rotary suction dry sandblasting machine. Background Art

[0002] The rotary suction dry sandblasting machine uses compressed air as the power. Through the negative pressure formed in the spray gun by the high-speed movement of the air flow, the abrasive is sucked into the spray gun through the sand conveying pipe and ejected through the nozzle, and sprayed onto the surface to be processed to achieve the expected processing purpose. In the rotary suction dry sandblasting machine, the compressed air is both the feeding power and the accelerating power of the jet.

[0003] In the existing rotary suction dry sandblasting machine, an air suction hood is arranged at the top of the sandblasting chamber to suck away the raised dust. However, the dust collection coverage range of this fixed-position dust collection mechanism is limited. Due to the fixed position, it can only suck dust in a specific area and cannot cover all corners inside the machine, which easily leads to some dust not being sucked away in time. In addition, the air flow organization is unreasonable, which may cause local air flow blockage, affect the dust collection effect, and even cause eddy currents in some areas, resulting in local accumulation of dust. To solve the above problems, we propose an improved dust collection system for this rotary suction dry sandblasting machine. Summary of the Utility Model

[0028] In the present utility model, a second motor 23 is fixedly connected to the side wall of the treatment box 8, and the output shaft of the second motor 23 is fixedly connected to the reciprocating lead screw 16, so that the reciprocating lead screw 16 does not need to be rotated manually, thereby improving the automation degree of the device.
