[0029] Clamping assembly 3 is disposed inside the rotating drum 22;

[0030] The receiving component 2 also includes a turntable 27, a fixing ring 28, and a fixing post 29. The fixing ring 28 is fixedly installed at the lower end of the fixing cylinder 21. The cross-section of the turntable 27 is polygonal. Each side of the turntable 27 is rotatably connected to each driven gear 25. Multiple fixing posts 29 are provided. Each fixing post 29 is fixedly installed on the lower end face of the turntable 27, and the lower end of the fixing post 29 is slidably placed on the upper end face of the fixing ring 28.

[0031] The fixing ring 28 has a groove 281, and the lower end of the fixing post 29 has a swivel ball 291, which is rotatably placed in the groove 281.

[0032] The clamping assembly 3 includes a clamping plate 31, a slider 32, a telescopic column 33, and a spring 34. The lower inner end face of the rotating cylinder 22 has multiple moving grooves 221, which are circumferentially distributed around the axis of the rotating cylinder 22. Multiple clamping plates 31 and sliders 32 are provided. Each slider 32 is movably placed in a moving groove 221. The clamping plate 31 is fixedly installed on the upper end face of the slider 32. Multiple sets of telescopic columns 33 and springs 34 are provided. Multiple sets of telescopic columns 33 and springs 34 are provided in each set. The two ends of the telescopic column 33 and the two ends of the spring 34 are connected to the outer wall of the clamping plate 31 and the inner wall of the rotating cylinder 22. The spring 34 is sleeved on the telescopic column 33.

[0033] The inner wall of the clamping plate 31 is set in an arc shape, and the upper end of the clamping plate 31 is set in an arc shape that slopes downward.

[0034] The upper end of the rotating drum 22 has a mounting groove 222 and a heating resistance wire 223, with the heating resistance wire 223 fixedly mounted in the mounting groove 222.

[0035] Working principle and usage process of this utility model:

[0036] First, the worker presses the aluminum can to be flipped downwards from the upper end of the clamping plate 31 until the lower end face of the aluminum can is in contact with the bottom wall of the rotating cylinder 22. At this time, the slider 32 drives the clamping plate 31 to slide along the moving groove 221. Under the action of the spring 34, the outer circumference of the aluminum can is in contact with the inner circumference of the multiple clamping plates 31. In this way, the aluminum can is fixed between the multiple clamping plates 31. Subsequently, the heating resistance wire 223, after being energized, dissipates heat and heats the mouth of the aluminum can through heat transfer, thereby reducing the yield strength of the aluminum can, making it more flexible and easier to form, thus reducing the risk of cracks and breakage during the flipping process.

[0037] Then, the motor 26 after starting drives the drive gear 24 to rotate, which in turn drives multiple driven gears 25 meshing with the drive gear 24 to rotate synchronously along the gear ring 23, so that the rotating cylinder 22 placed on the upper end face of the driven gear 25 rotates around its own axis. At the same time, the fixed column 29 placed on the lower end face of the driven gear 25 also rotates along the slide groove 281. By setting the rotating ball 291, the friction between the fixed column 29 and the fixed ring 28 is reduced, thereby improving the service life of the equipment.

[0038] While the rotating drum 22 drives the aluminum can to rotate, the flanging machine 12 installed on the fixed frame 11 moves up and down intermittently. By rotating the aluminum can, the flanging force applied by the flanging machine 12 can be evenly distributed on the edge of the aluminum can, thereby achieving more uniform deformation, avoiding local stress concentration that could cause cracks or breaks in the aluminum can, ensuring a tighter fit between the aluminum can opening and the can lid, improving sealing performance, and reducing the risk of leakage.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
