Description
Technical Field
[0001] The utility model relates to the technical field of vacuum can sealing machines, in particular to an anti-deviating can sealing machine. Background Art
[0002] Food cans need to be sealed with sealed packaging to block the circulation of air and prevent contamination by bacteria and water outside the can. After being sealed, the food cans can be sterilized and stored for a long time, ensuring that the food is still in a healthy state after reaching the hands of consumers. When processing canned food, the product is generally added to the can body first, and then it is vacuum sealed to complete the canning and packaging of the food. At present, vacuum canning machines are usually used for canning. Existing vacuum canning machines are usually composed of structures such as a canning head, a conveyor belt and a positioning plate. That is, the food cans to be packaged are conveyed to the positioning plate corresponding to the canning head by the conveyor belt and the placement plate thereon, and the air in the food can is extracted by the canning head, and the can is sealed.
[0003] The radius of the positioning groove in the positioning plate is usually relatively wide. When the food can is conveyed to the positioning plate via the conveyor belt, since the can body is not fixed, its own stability is relatively poor, and it is easy to shift during sealing, and it is easy to shake or tip over, which requires manual correction. At the same time, when packaging containers of different sizes are being sealed, each can only seal food cans of one specification and size. If there are multiple specifications of food cans, multiple corresponding positioning plates are required, which is inconvenient for production and increases production costs. Utility Model Content

When the packaging is completed, the food can is taken out by the robot arm, and the sliding cylinder can be driven to reset under the action of the third spring, thereby facilitating the next packaging operation. The structure is simple and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] When the anti-deviating can sealing machine of the utility model is used, the food can to be sealed is placed on the fixed plate 53 in the circular groove 41 of the slide seat 4. The inclined angle of the arc plate 61 facilitates the insertion of the food can. With the cooperation of the first spring 64, the telescopic inner rod 63 and the connecting outer tube 62, the side wall of the arc plate 61 can be clamped. At the same time, under the action of the gravity of the food can itself, the bottom of the food can contacts the suction cup 54 and pushes the sliding cylinder 52 to move downward along the fixed cylinder 51 through the fixed plate 53, and at the same time drives the connecting tube 56 to move downward along the vertical tube 55. The connecting tube 56 can gradually exhaust the air in the vertical tube 55 during the movement. When the connecting tube 56 moves to the bottom of the vertical tube 55, the connecting tube 56 can close one end of the exhaust pipe 58, so that the connecting tube 56 is closed from the outside. A certain suction force will be generated at the suction cup 54, so that the bottom of the food can can be sucked to achieve the purpose of fixing the food can. When the food can is packaged, the food can can be taken out by an external manipulator, and the sliding cylinder 52 can be reset under the action of the third spring 57. At this time, the connecting tube 56 is connected to the outside, which is convenient for the next operation.
