[0037] The first conveyor frame 10 is provided with a plurality of loading stations along its loading direction A;

[0038] The second conveyor frame 20 is arranged below the first conveyor frame 10 and has a plurality of unloading stations arranged along its unloading direction B;

[0039] The first conveying device 30 is arranged on the first conveying frame 10, and is used to convey the rollers to be sandblasted to pass through the loading stations in sequence;

[0040] The second conveying device 40 is disposed on the second conveying frame 20 and is used to convey the sandblasted drums to pass through the unloading stations in sequence;

[0041] The first detection device 51 is arranged at the loading station and is used to detect whether there is a roller to be sandblasted at the loading station;

[0042] The second detection device 52 is arranged at the unloading station, and is used to detect whether there is a sandblasted roller at the unloading station.

[0043] In the utility model, the sandblasting machine includes a double-layer sandblasting drum conveying device, a material moving device and a plurality of sandblasting machine bodies. The material moving device is preferably a manipulator. The double-layer sandblasting drum conveying device is used to convey the drum to be sandblasted with workpieces and the sandblasted drum that has been sandblasted. Specifically, the drums to be sandblasted on the loading station of the first conveyor rack 10 are transferred one by one to the sandblasting machine body for sandblasting by the manipulator. When the sandblasting is completed, the manipulator takes the sandblasted drum out of the sandblasting machine body and places it on the unloading station of the second conveyor rack 20, re-grabs the drum to be sandblasted on the loading station of the first conveyor rack 10 and places it in the electric sandblasting drum device, and the cycle is repeated.

[0044] Further, take the first conveyor rack 10 having three loading stations as an example: the worker first places the first roller to be sandblasted on the first conveyor rack 10 one by one along the loading direction A. When the first detection device 51 on the first loading station detects that there is a roller to be sandblasted on the first loading station, it sends a command to the controller, and the controller controls the first conveyor device 30 to drive the roller to be sandblasted to move to the second loading station; the worker then places the second roller to be sandblasted on the first loading station. When the first detection device 51 on the first loading station detects again that there is a roller to be sandblasted and there is also a roller to be sandblasted on the second loading station, it sends a command to the controller, and the controller controls the first conveyor device 30 to drive the first roller to be sandblasted to move to the third loading station and drive the second roller to be sandblasted to move to the second The worker then places the third roller to be sandblasted on the first loading station. When the first detection devices 51 on the first loading station, the second loading station and the third loading station all detect the existence of the roller to be sandblasted, a command is sent to the controller. The controller first controls the lifting device 60 to lift the first roller to be sandblasted on the third loading station to separate from the first conveying device 30, and then controls the first conveying device 30 to drive the second roller to be sandblasted to move to the third loading station and the third roller to be sandblasted to move to the second loading station. Finally, the lifting device 60 is controlled to drop the first roller to be sandblasted on the third loading station back to the third loading station, so as to avoid the first roller to be sandblasted from rubbing against the first conveying device 30 at the third loading station.

[0045] Furthermore, the sandblasted drum is placed on the second conveyor rack 20 under the grip of the robot. When the second detection device 52 detects the presence of the sandblasted drum on the first unloading station, it sends an instruction to the controller, and the controller controls the second conveying device 40 to convey the sandblasted drum along the unloading direction B.
