[0023] As Figure 1 shown in the figures, a can-sealing device for a clip includes a workbench 1 and a placing plate 2 provided thereon. In this embodiment, a number of groups of placing plates 2 are distributed on the workbench 1. The placing plate 2 is circularly arranged. A number of groups of through slots 4 for placing round boxes 26 are equidistantly opened along the circumference of the placing plate 2. A sealing cover assembly 3 is provided on the workbench 1. The sealing cover assembly 3 adopts the technical equipment commonly used by those skilled in the art. Its purpose is to press the sealing cover onto the round box 26. An arc-shaped guiding plate 5 is provided outside the placing plate 2. The guiding plate 5 is provided on the workbench 1, and an opening 6 is opened at the position directly below the sealing cover assembly 3 on the guiding plate 5. A cylinder 7 is provided on the upper side of the workbench 1 at the opening 6. The cylinder 7 is located outside the guiding plate 5, and the top end of the piston rod of the cylinder 7 is connected to a slider 8. Driven rods 9 are oppositely arranged on the left and right sides of the outer wall of the slider 8. The driven rods 9 are rotatably connected to the slider 8 through a rotating rod 10. The two ends of the two driven rods 9 away from the slider 8 are rotatably connected to a clamping block 11 through a rotating rod 16. A torsion spring 17 is sleeved on the outer wall of the rotating rod 16. Its purpose is to be able to reset after the clamping block 11 changes its position. The two ends of the two driven rods 9 away from the clamping block 11 are provided with arc-shaped plates 12. A placing groove (not marked in the drawing) is provided at the end of the slider 8 facing the cylinder 7. A gear 14 is horizontally rotatably arranged in the placing groove. A rack 13 meshing with the gear 14 is provided on the arc-shaped plate 12. In this embodiment, the center of the arc-shaped plate 12 coincides with the central axis of the rotating rod 10. Its purpose is that when the arc-shaped plate 12 is driven, the rotating rod 10 can rotate around its own central axis.

[0024] An electric motor 15 is provided on the upper side of the outer wall of the slider 8. The gear 14 is sleeved on the output shaft of the electric motor 15. Its purpose is to be able to drive the gear 14 to rotate through the electric motor 15, reducing manual operation by personnel.

[0025] As Figure 5As shown in the figure, a through hole 18 is provided in the middle of the slider 8. The top end of the piston rod of the air cylinder 7 is provided with a push rod 20. The front end of the push rod 20 passes through the through hole 18. An electromagnetic suction block 19 is arranged on the inner wall of the through hole 18. A magnetically attracted block 21 magnetically matched with the electromagnetic suction block 19 is arranged on the outer wall of the push rod 20. An electromagnetic suction block 23 is arranged on the inner wall of the opening 6. A magnetically attracted block 22 magnetically matched with the electromagnetic suction block 23 is arranged on the outer wall of the slider 8. An arc-shaped push plate 24 is arranged at one end of the push rod 20 away from the air cylinder 7. Flexible pads 25 are arranged on both the clamping block 11 and the push plate 24. The purpose is to make the contact with the outer wall of the round box 26 in the through groove 4 softer and reduce the extrusion deformation of the round box 26.

[0026] When the position adjustment of the round box 26 in the through groove 4 is not required, the air cylinder 7 is in a retracted state, the slider 8 is located outside the guide plate 5, the motor 15 is in a stopped state, the electromagnetic suction block 19 and the electromagnetic suction block 23 are in a de-energized state, and the torsion spring 17 is in an initial state without being twisted. The placement disk 2 rotates to move the round boxes 26 in the through groove 4 one by one to directly below the capping assembly 3 for capping.

[0027] When the position of the round box 26 in the through groove 4 is offset and needs to be adjusted, the round box 26 is directly below the capping assembly 3. The operator controls the electromagnetic suction block 19 to be energized through the control system. The air cylinder 7 extends. The electromagnetic suction block 19 is magnetically matched with the magnetically attracted block 21. Thus, the air cylinder 7 drives the push rod 20 to synchronously push the slider 8 to move into the opening 6, so that the two driving rods 9 pass through the opening 6 and enter the inside of the through groove 4, located at both ends of the round box 26 in the through groove 4. The air cylinder 7 stops moving briefly. At this time, the electromagnetic suction block 19 is de-energized and the electromagnetic suction block 23 is energized. Thus, the slider 8 is limited at the opening 6. The air cylinder 7 and the motor 15 start. The air cylinder 7 pushes the push plate 24 to synchronously fit the round box 26 through the push rod 20. The purpose is to make the rear end of the round box 26 fit the inner wall of the through groove 4. The motor 15 rotates forward to drive the gear 14 to mesh with the rack 13 for transmission. The arc-shaped plate 12 pushes the driving rod 9 to rotate around the central axis of the rotating rod 10, so that the front end of the driving rod 9 approaches the round box 26 in the through groove 4. The two opposite clamping blocks 11 start to contact the round box 26 and push the round box 26 to move in the through groove 4 to adjust its position, eliminating the need for manual adjustment by the operator and reducing the labor intensity of the operator.

[0028] After the round box 26 is moved, the operator can control the air cylinder 7 to retract through the control system, making the electromagnetic suction block 19 face the magnetically attracted block 21. The electromagnetic suction block 23 is de-energized and the electromagnetic suction block 19 is energized. The air cylinder 7 stops briefly. The motor 15 starts to rotate in reverse, indirectly driving the clamping block 11 to reset and not contact the outer wall of the round box 26. Then the air cylinder 7 continues to retract, causing the slider 8 to disengage from the opening 6 and be located outside the guide plate 5 to avoid interference when the placement disk 2 rotates.

[0029] The above embodiments are illustrative of the present utility model and not restrictive thereof. Any solution obtained by simply transforming the present utility model falls within the protection scope of the present utility model.
