[0027] Reference Figures 1 to 3 , an electric sandblasting drum device, comprising a base 10, a placement frame 20, a driving device 30, a first detection device 40 and a second detection device 50;

[0028] The base 10 is provided with a rotating shaft 60, and the rotating shaft 60 is provided with an axially penetrating detection groove 61;

[0029] The placement rack 20 is connected to the front end of the rotating shaft 60 and is used to place the roller 70;

[0030] The driving device 30 is disposed on the base 10 and connected to the rotating shaft 60, and is used to drive the rotating shaft 60 to rotate;

[0031] The first detection device 40 is disposed in the detection slot 61 and is used to detect whether there is a roller 70 on the placement rack 20;

[0032] The second detection device 50 is disposed on the base 10 and is used to detect the angle of the rotating shaft 60 .

[0033] In the present invention, the sandblasting machine includes a feeding device, a material moving device and a plurality of sandblasting machine bodies. The material moving device is preferably a manipulator. The feeding device is used to transport a roller 70 loaded with a workpiece and a roller 70 that has been sandblasted. The electric sandblasting roller device is installed in the sandblasting machine body. The roller 70 in the feeding device is transferred to the electric sandblasting roller device in the sandblasting machine body by the manipulator. Specifically, the roller 70 is placed on the placement rack 20. Since the placement rack 20 is provided with a detection hole arranged opposite to the first detection device 40, the first detection device 40 can detect whether there is a roller 70 on the placement rack 20 through the detection hole; secondly, when the manipulator exits the sandblasting machine body, the driving device 30 is started to drive the rotating shaft 60 on the machine base 10 to rotate, so that the rotating shaft 60 drives the first detection device 40 to drive ... The device 40 rotates together, and the sandblasting gun is started to sandblast the workpiece in the drum 70; when the sandblasting is completed, the driving device 30 continues to operate until the second photoelectric sensor 52 detects the trigger sheet 51, thereby judging the angle of the rotating shaft 60 (the placement rack 20), and then feeding back to the controller, which can provide an accurate grasping position for the manipulator (avoiding the side ears on the drum 70), and the manipulator takes out the sandblasted drum 70 from the sandblasting machine body, re-grabs another drum 70 to be sandblasted and places it in the electric sandblasting drum device, and so on. The advantage of the utility model is that: through the above structure, it is possible to detect whether there is a drum and the angle of the drum, so as to cooperate with the material moving device of the transfer drum to realize automatic material taking and unloading, and then it is suitable for a fully automatic sandblasting machine, and has very good practicality.

[0034] In one embodiment, the driving device 30 includes a motor 31 and a reducer 32 connected to the output end of the motor 31, and the rotating shaft 60 is passed through the reducer 32 and connected to the reducer 32; in this setting, the reducer 32 preferably adopts a worm gear structure to change the speed ratio, and then reduces the speed of the motor 31 and outputs it to the rotating shaft 60, so as to prevent the roller 70 from rotating too fast and causing the workpiece to be thrown out.

[0035] In one embodiment, a conductive slip ring 80 is disposed at the rear end of the rotating shaft 60 , and the lead wires of the first detection device 40 are connected to the conductive slip ring 80 ; this arrangement can prevent the lead wires of the first detection device 40 from being twisted together while following the rotation of the rotating shaft 60 .

[0036] In one embodiment, the placement rack 20 has a placement cavity 21 with a non-circular transverse cross-sectional profile, and the roller 70 is placed in the placement cavity 21; this setting enables the roller 70 to limit its position by relying on its own structure, and no additional connecting structure is required to fix the roller 70 and the placement rack 20 together.

[0037] In one embodiment, the inner diameter of the placement rack 20 gradually decreases from front to back; this setting enables the roller 70 to self-fit by relying on the change in the inner diameter when in contact with the placement rack 20, thereby improving the fit between the roller 70 and the placement rack 20, which is beneficial to improving the stability of the roller 70 when rotating.

[0038] As a preferred embodiment of the first detection device 40, the first detection device 40 is configured as a first photoelectric sensor.

[0039] As a preferred embodiment of the second detection device 50 , the second detection device 50 includes a trigger piece 51 disposed at the rear end of the rotating shaft 60 and a second photoelectric sensor 52 disposed on the base 10 .
