Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum foil sealing machines, and specifically relates to a positioning mechanism for an aluminum foil sealing machine. Background Art

[0002] The electromagnetic aluminum foil sealing machine is a machine that uses the principle of electromagnetic induction heating to seal the aluminum foil lid of food or medicine containers. It applies a high-frequency electromagnetic field to the aluminum foil lid, causing the aluminum foil to generate induction heating, thereby sealing the container mouth and ensuring that the food or medicine inside the container remains sealed and fresh.

[0003] At present, a conveyor belt is usually set under the electromagnetic aluminum foil sealing machine, and then the container is placed on the conveyor belt. When the container passes under the electromagnetic aluminum foil sealing machine, the electromagnetic aluminum foil sealing machine seals the aluminum foil at the container mouth. Due to the different sizes of containers, when sealing containers of different specifications, it may be inconvenient to adjust the container to move on the central axis of the conveyor belt, which may cause deviations when sealing the container. Secondly, when sealing some containers, it may be inconvenient to stabilize the container under the electromagnetic aluminum foil sealing machine, thereby greatly reducing the accuracy of container sealing.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0029] Reference Figure 1 The lifting assembly 2 includes a first threaded rod 21 rotatably connected to the frame 1, and the outer wall of the first threaded rod 21 is threadedly connected to the first block 22. The inner wall of the first block 22 is adapted to the outer wall of the first threaded rod 21.

Through the action of the belt 73, the two transmission wheels 72 rotate at the same time, thereby causing the two second threaded rods 62 to rotate.

[0032] Working principle: First, the height of the electromagnetic aluminum foil sealing machine body 3 is adjusted according to the height of the plastic bottle. The PLC control cabinet 5 controls the operation of the motor 24, and the first threaded rod 21 rotates accordingly. The first set of blocks 22 drives the stabilizing plate 25 to move and adjust. The stabilizing plate 25 and the vertical rod 26 increase the stability of the up and down movement of the first set of blocks 22, so that the connecting plate 23 drives the electromagnetic aluminum foil sealing machine body 3 to move and adjust, thereby adjusting the vertical movement of the electromagnetic aluminum foil sealing machine body 3, and adjusting the bottom of the electromagnetic aluminum foil sealing machine body 3 to a position higher than the top height of the product. When sealing the plastic bottle, the plastic bottle is laid on the conveyor belt 4, and the PLC control cabinet 5 controls the operation of the conveyor belt 4, so that the plastic bottle is located below the electromagnetic aluminum foil sealing machine body 3 and moves horizontally. The electromagnetic aluminum foil sealing machine body 3 heats the aluminum foil seal through a high-frequency electromagnetic field, thereby bonding it to the mouth of the plastic bottle;

[0033] During the process of sealing the plastic bottles, the positions of the front and rear transmission rollers 66 are adjusted, and the turntable 71 drives one of the second threaded rods 62 to rotate. Under the action of the belt 73, the two second threaded rods 62 rotate at the same time, thereby causing the second set of blocks 63 to drive the bottom rod 64 to rotate, and the horizontal plate 65 moves toward the direction close to the electromagnetic aluminum foil sealing machine body 3, so that the transmission roller 66 moves to contact the plastic bottle transmitted on the conveyor belt 4, thereby pushing the plastic bottle to move on the central axis of the conveyor belt 4, further increasing the accuracy of the electromagnetic aluminum foil sealing machine body 3 in sealing the plastic bottle. At the same time, the position of the second set of blocks 63 can be adjusted again. When the transmission roller 66 moves to be close to the plastic bottle, the plastic bottle can be clamped and stabilized under the electromagnetic aluminum foil sealing machine body 3 to prevent the plastic bottle from tipping over during the heating process.
