The interior of the piston column 17 is provided with an air vent 31. The air vent 31 is used to connect the space between the movable cylinder 24 and the piston column 17 to the atmosphere, so that when the sealing cylinder 7 is in a negative pressure state, the atmospheric pressure can push the circular cutting knife 25 to move.

The bottom of the limit block 26 is in contact with the circular cutter 25. When the piston column 17 moves downward, the piston column 17 can drive the circular cutter 25 to move downward through the limit block 26, so that the air vent 31 can maintain movement with the space between the movable cylinder 24 and the piston column 17, and thereby the space between the movable cylinder 24 and the piston column 17 can maintain communication with the atmosphere.

[0032] In another embodiment provided by the present invention, a fixing ring 3 is fixed to the top outer wall of the rotating disk 2, and the fixing rings 3 are symmetrically distributed on the rotating disk 2, and the number of the fixing rings 3 is at least two, and a conical ring 32 is fixed to the top outer wall of the fixing ring 3, and the packaging can 4 is located inside the fixing ring 3 and the conical ring 32, and the interior of the fixing ring 3 has a rubber layer, so that the packaging can 4 cannot move horizontally inside the fixing ring 3; a retaining ring 33 is fixed to the inner wall of the sealing cylinder 7, and a sealing ring 34 located inside the sealing cylinder 7 is fixed to the bottom of the retaining ring 33, and the sealing ring 34 is made of fluororubber material, and the sealing ring 34 is adapted to the conical ring 32. When the sealing cylinder 7 contacts the conical ring 32 on the rotating disk 2, the sealing ring 34 is used to seal the sealing cylinder 7 and the rotating disk 2.

[0033] In another embodiment provided by the present invention, the driving mechanism includes a bracket 5 fixed to the base 1, a cylinder 6 is fixed to the top outer wall of the bracket 5, the output shaft of the cylinder 6 is fixed to the sealing cylinder 7, and the cylinder 6 is used to drive the sealing cylinder 7 to move up and down; a rotating shaft 10 is fixed at the bottom center of the rotating disk 2, and the bottom end of the rotating shaft 10 is connected to the base 1 through a bearing, and a motor 9 is fixed inside the base 1, and the output shaft of the motor 9 is connected to the rotating shaft 10 through a key, and the rotating disk 2 is driven to rotate by the motor 9, and the motor 9 has a built-in brake to achieve an emergency stop of the rotating disk 2, and a sensing block 14 is fixed to the bottom outer wall of the rotating disk 2, and the sensing block 14 is located at the bottom of the fixing ring 3, and the number of the sensing blocks 14 corresponds to the fixing ring 3, and a proximity sensor 13 is fixed to the top outer wall of the base 1. When the sensing block 14 corresponds to the proximity sensor 13, the center of the packaging can 4 is exactly in contact with the sealing ring 3. The center of the cylinder 7 corresponds to that of the cylinder 7. A control host 35 is fixed inside the base 1. The proximity sensor 13 and the motor 9 are electrically connected to the control host 35 through wires, and the control host 35 is used to control the motor 9 to work and stop; an air intake pipe 19 is welded to the top outer wall of the sealing cylinder 7. The air intake pipe 19 connects the interior of the cylinder 16 with the atmosphere. The top of the air intake pipe 19 is connected to a filter assembly 20. The filter assembly 20 can filter dust in the air to prevent dust from entering the interior of the cylinder 16; a support block 11 is fixed to the bottom outer wall of the rotating disk 2, and a support wheel 12 is rotatably connected to the inside of the support block 11. The bottom of the support wheel 12 is in contact with the base 1, and the support wheel 12 is used to support the rotating disk 2, so that the rotating disk 2 is more stable when rotating, and the number and position of the support wheels 12 correspond to the fixed ring 3, so that the rotating disk 2 is easy to maintain force balance.

[0034] Working principle: When it is necessary to seal the packaging can 4, first connect the solenoid valve 8 to the negative pressure system, then place the packaging can 4 inside the fixed ring 3, and then drive the rotating disk 2 to rotate through the motor 9. When the induction block 14 at the bottom of the rotating disk 2 corresponds to the proximity sensor 13, the proximity sensor 13 transmits an electrical signal to the control host 35, and the control host 35 controls the motor 9 to stop rotating and brake. At this time, the center of the packaging can 4 just corresponds to the center of the sealing tube 7. Then, place the sealing film 15 on the packaging can 4, and then through the air The cylinder 6 drives the sealing cylinder 7 to move downward, so that the bottom of the sealing cylinder 7 cooperates with the conical ring 32, and then the solenoid valve 8 is controlled by the control host 35 to connect the negative pressure system with the sealing cylinder 7, and then the negative pressure system extracts the air inside the sealing cylinder 7. At this time, the air inside the packaging can 4 is also extracted by the negative pressure, so that the inside of the sealing cylinder 7 forms a negative pressure state. At this time, the atmospheric pressure pushes the piston column 17 to move downward. At this time, the block 21 gradually compresses the spring 23 until the heating plate 18 presses the sealing film 15 and the packaging can 4 tightly, and then The sealing film 15 is heated by the heating plate 18, so that the sealing film 15 seals the packaging can 4 under negative pressure; after the heating plate 18 contacts the sealing film 15, the piston rod 17 is blocked by the packaging can 4 and stops descending. As the air pressure inside the sealing cylinder 7 continues to decrease, the atmospheric pressure pushes the movable cylinder 24 downward, and then the circular cutting knife 25 cuts off the excess part of the sealing film 15, and the cut residue is sleeved on the packaging can 4, and then the electromagnetic valve 8 is controlled by the control host 35 to connect the sealing cylinder 7 to the atmosphere. At this time, the sealing cylinder 7 The internal negative pressure is released, and the piston column 17 and the circular cutting knife 25 are reset by spring 1 23 and spring 2 30 respectively, and the sealing cylinder 7 is driven to rise by the cylinder 6. When the sealing cylinder 7 is higher than the packaging can 4, the motor 9 is controlled by the control host 35 to drive the rotary disk 2 to rotate, so that the next packaging can 4 is located at the bottom of the sealing cylinder 7. Then, the sealed packaging can 4 and the remaining sealing film 15 cut off can be removed from the rotary disk 2 together, so that the unsealed packaging can 4 is placed inside the fixed ring 3 of the rotary disk 2.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
