[0002] Packaging equipment is the machinery and equipment used to place products into appropriate packaging and prepare them for shipping or storage. These devices can automate the packaging process, increasing production efficiency and reducing labor costs.

[0003] During the packaging process, after the packaging bag is lifted, it is often necessary to tighten the bag opening so that the packaging bag can be tied or sealed. However, this step of tightening the bag opening often requires manual intervention, and the existing rack does not have a mechanism that can achieve this step.

[0004] This results in a low degree of automation of packaging equipment and requires excessive manual intervention. Utility Model Content

By providing a second bracket 220, the suction component is raised and higher than the bag gathering mechanism 300, so that when the bag gathering mechanism 300 gathers the bag, the bag gathering part is below the bag opening, preventing the bag gathering mechanism 300 from closing the bag opening too close to the bag opening, causing the entire packaging bag and packaging film to slip out of the bag gathering mechanism 300. By providing a film suction bracket 230 on the film suction cylinder 240, the film suction components 210 arranged on the film suction bracket 230 can be more easily arranged relative to each other, and it is also less likely that the two sides of the bag will be uneven when lifting the bag.
