The upper surface of the primary motor 8 is fixedly connected to the mounting bracket 1, the lower surface of the turntable 9 is rotatably connected to the positioning component 6, the output end of the primary motor 8 is fixedly connected to the turntable 9, the upper surface of the turntable 9 is fixedly connected to the fixed block 10, the inner wall of the fixed block 10 is fixedly connected to the electric telescopic rod 11, and the end of the electric telescopic rod 11 away from the fixed block 10 is fixedly connected to the anti-slip plate 12. An aluminum can 22 is provided on the upper surface of the turntable 9, and an aluminum can lid 23 is provided on the upper surface of the aluminum can 22.

[0026] The anti-pressure component 7 includes a baffle 13, a screw 14, a U-shaped frame 15, a second rotating shaft 16, and an anti-pressure wheel 17. The lower surface of the lifting plate 3 is fixedly connected to the baffle 13. The inside of the baffle 13 is threadedly connected to the screw 14. The end of the screw 14 away from the baffle 13 is rotatably connected to the U-shaped frame 15. The inside of the U-shaped frame 15 is rotatably connected to the second rotating shaft 16. The side surface of the second rotating shaft 16 is fixedly connected to the anti-pressure wheel 17. A limit plate 18 is fixedly connected inside the baffle 13. A T-shaped slider 19 is fixedly connected to the upper surface of the U-shaped frame 15. The side surface of the T-shaped slider 19 is slidably connected to the limit plate 18.

[0027] Working principle: In use, first place the aluminum can 22 on the turntable 9, then place the aluminum lid 23 at the opening of the aluminum can 22. First, activate the two electric telescopic rods 11 to push the anti-slip plate 12 to the outer wall of the aluminum can 22, so that it presses the aluminum can 22 tightly to achieve clamping and positioning. Then, rotate the screw 14. Since the screw 14 is threadedly connected to the baffle 13, the screw 14 pushes the U-shaped frame 15 and the anti-pressure wheel 17 to move closer to the U-shaped frame 15 during rotation. When the anti-pressure wheel 17 and the edge-spinning pressure wheel 5 press the edges of the aluminum can 22 and the aluminum lid 23 tightly, the required deformation is produced. When tightening the check nut 20 to limit the screw 14, start the No. 1 motor 8 to drive the can 22 and the lid 23 on the turntable 9 to rotate. During the rotation, the can is sealed by the pressure of the anti-pressure roller 17 and the rotating edge pressure roller 5. The mutual pressure of the anti-pressure roller 17 and the rotating edge pressure roller 5 can prevent the lid 23 from being flattened due to one-sided force. This makes the lid 23 less likely to be over-compressed and completely deformed during the rotating edge compression process, thereby improving the product qualification rate. The pressure can also be adjusted to achieve the processing of lids with different sealing requirements.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
