Description

Technical Field

[0001] This utility model relates to the field of packaging bag sealing technology, specifically to an exhaust clavicle operating mechanism. Background Technology

[0002] Self-sealing bags are compression-sealed packaging bags that can be used for packaging various products such as clothing and daily necessities. The bag opening typically features ribs (one or more ribs at the top and bottom) connected by interlocking snaps. During packaging, the product is placed inside the self-sealing bag, and air is expelled to compress the bag. Finally, the ribs are pressed to seal the bag opening, completing the sealing process.

[0003] In the existing packaging process of the above-mentioned products, the air is usually vented from the self-sealing bag and the ribs of the self-sealing bag are squeezed manually. When there are a large number of self-sealing bags to be sealed, the above manual methods require a lot of manpower and time. Utility Model Content

(2) Introducing the self-sealing bags to be sealed: The self-sealing bags containing clothing and other products are placed at the rear end of the lower conveyor belt 3. The opening of the self-sealing bag should be placed close to the side of the lower conveyor belt 3 so that the compression device 1 can compress the ribs of the bag opening. Placement position markers or placement position limiters can be set at the rear end of the lower conveyor belt 3 to better guide the placement of the self-sealing bags. Further, the self-sealing bags are conveyed forward by the lower conveyor belt 3 into the gap between the upper conveyor belt 2 and the lower conveyor belt 3. (3) Exhausting the self-sealing bags: The lower end face of the upper conveyor belt 2 is pressed down by the pressing device 4 so that the lower end face of the upper conveyor belt 2 performs planar compression on the self-sealing bags to expel the air inside the self-sealing bags. (4) Sealing the self-sealing bag: After the self-sealing bag has been degassed, it is further conveyed through the compression sealing device 1. When the upper and lower ribs of the self-sealing bag enter the gap between the upper clamping wheel 13 and the lower clamping wheel 14, the bag opening of the self-sealing bag contacts the upper clamping wheel 13 and the lower clamping wheel 14. At this time, the rotating upper clamping wheel 13 and the lower clamping wheel 14 squeeze the upper and lower ribs of the self-sealing bag to press and seal the bag opening, thereby completing the sealing process of the self-sealing bag.
