Description

Technical Field

[0001] This utility model relates to the field of vacuum sealing machine technology, and more specifically, to a suction cup-type vacuum machine. Background Technology

[0002] A vacuum sealing machine is used to seal food after it is placed in a packaging bag. The air inside the bag is then extracted using an air extraction device to achieve a predetermined vacuum level. By vacuuming the packaging bag, food spoilage can be effectively prevented and food can be preserved more easily.

[0003] When sealing with a separate top and bottom cover, the opening of the packaging bag is placed in the designated position, and then the top and bottom covers are pressed together by external force. The corresponding buckles on the top and bottom covers are used to lock them in place, keeping them in a pressed state. After sealing, the top and bottom covers are released from the buckle, and the sealed part of the packaging bag can be removed. In this method, the locking of the top and bottom covers usually requires manual pressing, and a certain amount of pressure is required. For people with less strength, it may be difficult to press them in place, resulting in the inability to seal the opening of the packaging bag.

[0033] The vacuum machine places the upper cover assembly 1 above the lower cover assembly 2 when performing the sealing operation, then the suction cup assembly 3 is in contact with the bonding area 4 under the action of gravity, and a space area is formed between the suction cup assembly 3 and the bonding area 4, which is communicated with the air extraction part 5; the air extraction part 5 works to extract air from the space area, so that the volume of the space area decreases under the action of negative pressure, the height of the suction cup assembly 3 decreases, and the upper cover assembly 1 and the lower cover assembly 2 are sealed and pressed together, so that the vacuum treatment of the suction cup assembly 3 can be stopped, and then the sealing operation can be performed; after the sealing operation is completed, the space area formed by the suction cup assembly 3 and the bonding area 4 is communicated with the outside atmosphere through the air release part 6, so that the air pressure in the space area is higher than the air pressure outside, so that the air pressure in the space area is increased, and the volume is increased, and the suction cup assembly 3 can be restored to the height before vacuumizing, at this time, the upper cover assembly 1 and the lower cover assembly 2 can be easily separated.

[0034] Through the above design, the air extraction part 5 extracts air from the space area formed by the suction cup assembly 3 and the bonding area 4, so that the upper cover assembly 1 and the lower cover assembly 2 can be sealed and pressed together, without manual pressing operation, which is convenient for people with less strength to use, and can ensure that the subsequent sealing operation is effectively performed, preventing the upper cover assembly 1 and the lower cover assembly 2 from being completely sealed and pressed together, which leads to the failure of sealing the packaging bag.

[0035] As shown in FIG. 1, Figure 2 In one embodiment, it further includes: a gas pipe adapter 7 connected with the suction cup assembly 3 through a first gas pipe 8, connected with the air extraction part 5 through a second gas pipe 9, and connected with the air release part 6 through a third gas pipe 10.
