[0041] When in use, the adjusting assembly 300 is adjusted by the adjuster 500 according to the diameter of the easy-open lid to be screwed, specifically by turning the knob 502. The rotation of the knob 502 will drive the adjusting shaft 501 to rotate. The adjusting shaft 501 is connected to the first connecting plate 205 through a thread. When the adjusting shaft 501 rotates, it moves in the first connecting plate 205. When the adjusting shaft 501 moves, it drives the adjusting block 503 to move. When the adjusting block 503 moves upward, the adjusting block 503 moves and contacts with the first wedge block 303. The four first wedge blocks 303 above the adjustment block 503 are synchronously driven to move outward. At this time, the first wedge block 303 will drive the third limiting rod 310 and the second spring 307 to move. When the third limiting rod 310 moves, it will move in the fourth connecting hole 210 of the connecting ring 207. The movement of the second spring 307 will push the third connecting plate 306 to move. The movement of the third connecting plate 306 will drive the hemming wheel 308 to move.

[0042] When the adjusting block 503 moves downward, the third spring 311 between the movable limit plate 301 and the connecting ring 207 is always in a compressed state, and the third spring 311 will provide a force to the movable limit plate 301 and push the movable limit plate 301 inward.

[0043] During the movement of the movable limit plate 301 and the third connecting plate 306, the first sliding fins 302 fixedly installed on both sides of the movable limit plate 301 and the second sliding fins 309 fixedly installed on both sides of the third connecting plate 306 both move in the limit groove 212. When the second sliding fins 309 move to the outermost side, the hem spinning wheel 308 is located at the edge of the movable groove 211. When the first sliding fin 302 moves to the innermost side, the movable limit plate 301 is located at the edge of the movable groove 211. Therefore, the limit groove 212 has a limiting effect on the movable limit plate 301 and the hem spinning wheel 308, and is convenient for maintaining the stability of the adjustment assembly 300 when adjusting the hem spinning wheel 308.

[0044] The edge spinning component 400 is adjusted by the regulator 500 according to the diameter of the easy-open lid to be edge-spinned, specifically, the knob 502 is rotated. The rotation of the knob 502 will drive the adjusting shaft 501 to rotate. The adjusting shaft 501 is connected to the third connecting plate 402 by a thread. When the adjusting shaft 501 rotates, it will move in the third connecting plate 402. When the adjusting shaft 501 moves, it will drive the adjusting block 503 to move. When the adjusting block 503 moves downward, the adjusting block 503 will drive the second wedge block 408 that fits with the adjusting block 503 to move outward. When the second wedge block 408 moves outward, it will drive the connecting rod 407 to move outward. The outward movement of the connecting rod 407 will move the extruding wheel 411 outward, thereby changing the distance between the extruding wheel 411 and the edge spinning wheel 308. The extruding wheel 411 is moved to a suitable position to spin the easy-open lids with different diameters.

[0045] When the adjusting block 503 moves upward, the fourth spring 409 between the second wedge block 408 and the fourth connecting plate 403 is always in a compressed state, and the fourth spring 409 will provide a force to the second wedge block 408 and push the second wedge block 408 inward, and the second wedge block 408 will move toward the adjusting block 503 and fit with the adjusting block 503, and the second wedge block 408 will drive the connecting rod 407 to move inward, and the connecting rod 407 will drive the extrusion wheel 411 and the sixth limit block 410 to move inward, so that the extrusion wheel 411 can be moved to a suitable position to spiral the edge of the easy-pull lids of different diameters, and the sixth limit block 410 can limit the connecting rod 407 so that the extrusion wheel 411 is always on the outside of the fourth connecting plate 403.

[0046] After the hemming assembly 400 and the adjusting assembly 300 are adjusted, the hemming process can be performed on the easy-open lid. Specifically, the telescopic rod 405 is adjusted to drive the lower pressing plate 406 to clamp the easy-open lid between the lower pressing plate 406 and the third connecting plate 306, and the motor in the connecting rod 407 is started to drive the extrusion wheel 411 to rotate. At the same time, the first motor 112 is started. The rotation of the first motor 112 will drive the second rotating shaft 113 to rotate. The rotation of the second rotating shaft 113 will drive the second gear 114 to rotate. The rotation of the second gear 114 will drive the first gear 109 to rotate.
