DETAILED DESCRIPTION

[0020] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0021] See also Figure 1-3 According to an embodiment of the utility model, a denture sandblasting device for cleaning sand pills includes a base 1, which is located at the bottom of the entire device. A rotating feeding mechanism 2 is installed on the top of the base 1, and a sandblasting chamber 3 is installed on one side of the top of the base 1. A loading and unloading mechanism 4 is installed at the side end of the sandblasting chamber 3 and above the rotating feeding mechanism 2.

[0022] The loading and unloading mechanism 4 first loads the materials to the rotary feeding mechanism 2 , and then performs sandblasting in the sandblasting room 3 . After completion, the materials are sent out by the rotary feeding mechanism 2 and then unloaded by the loading and unloading mechanism 4 .

[0023] In this embodiment, the loading and unloading mechanism 4 includes a slide groove 5 opened on the side of the sandblasting chamber 3, and a bidirectional screw rod 6 is rotatably connected between the side walls of the slide groove 5 through a bearing. One end of the bidirectional screw rod 6 passes through the slide groove 5 and is installed on the output end of the first motor 7. The first motor 7 is fixedly installed on the outside of the sandblasting chamber 3, and both ends of the bidirectional screw rod 6 are threadedly connected with a moving block 8.

[0024] The first motor 7 drives the bidirectional screw 6 to rotate, and the bidirectional screw 6 drives a pair of moving blocks 8 to move toward or away from each other.

[0025] In this embodiment, a cylinder 9 is fixedly mounted at the end of the moving block 8, and the output end of the cylinder 9 is downward and connected to the first suction cup 10 through a piston rod.

[0026] The cylinder 9 drives the first suction cup 10 to rise and fall through the piston rod, thereby grabbing or releasing the denture.

[0027] In this embodiment, the rotary feeding mechanism 2 includes a mounting groove 11 opened on the top of the base 1, and an annular groove 12 is opened at the bottom of the mounting groove 11. Multiple groups of rollers 13 are rollingly connected to the annular groove 12, and the rollers 13 are equidistantly installed at the bottom of the turntable 14 through a rotating connecting piece.

[0028] The roller 13 is used to support the rotating disk 14 , and the annular groove 12 is used to limit the roller 13 .

[0029] In this embodiment, a second motor 15 is fixedly installed in the middle of the installation groove 11, and the output end of the second motor 15 is connected to the cavity opened at the bottom of the turntable 14 upward through a rotating rod. Installation cavities 16 are equidistantly opened around the turntable 14, and a gear 17 is rotatably connected in the installation cavity 16.

[0030] The second motor 15 drives the turntable 14 to rotate via a rotating rod.

[0031] In this embodiment, the gear 17 meshes with the gear ring 18 opened on the side wall of the installation groove 11, and a rotating shaft 19 is installed on the axis above the gear 17 and passes through the top of the rotating disk 14. A second suction cup 20 is fixedly installed on the top of the rotating shaft 19.

[0032] When the turntable 14 rotates, the gear 17 is also driven to move together. Due to the meshing gear ring 18, the gear 17 itself is also rotated, the gear 17 drives the rotating shaft 19 to rotate, the rotating shaft 19 drives the second suction cup 20 to rotate, thereby driving the denture to rotate, so that the sandblasting equipment can spray more comprehensively and thoughtfully, thereby ensuring the sandblasting effect.

[0033] In specific application, the equipment is first installed on one side of the conveyor belt for denture production, and the first motor 7 is started to drive the bidirectional screw 6 to rotate. The bidirectional screw 6 drives a pair of moving blocks 8 to move in opposite directions close to the conveyor belt in denture production. The cylinder 9 is started to drive the first suction cup 10 to descend through the piston rod. Then the first suction cup 10 on the right grabs the denture from the conveyor belt, and the first suction cup 10 on the left releases the sandblasted denture onto the conveyor belt. The above operation is repeated again, and the pair of moving blocks 8 are driven to move toward each other so that the first suction cup 10 is located directly above the second suction cup 20. The cylinder 9 is started again to drive the first suction cup 10 to descend. At this time, the first suction cup 10 on the right releases the denture to be sandblasted onto the second suction cup 20, and at the same time, the first suction cup 10 on the left grabs the denture sandblasted by the second suction cup 20. Finally, the second motor 15 is started to drive the turntable 14 to rotate through the rotating rod, thereby sending the denture into the sandblasting room 3, thereby realizing continuous production operations.
