Description

TECHNICAL FIELD

[0001] The utility model relates to the field of sanitary product packaging, especially a bag opening suction nozzle device based on a sanitary product packaging machine. BACKGROUND

[0002] With the rapid development of the sanitary product industry, the efficiency and quality requirements of sanitary product packaging machines are increasingly improved. In the packaging process of sanitary products, bag opening and suction nozzle are crucial links.

[0003] At present, the traditional sanitary product packaging machine adopts a relatively simple mechanical structure in terms of bag opening, such as forcibly opening the bag opening by mechanical clamps. This method not only easily damages the packaging bag, leading to a decrease in packaging sealing and affecting the product shelf life, but also has low bag opening efficiency, making it difficult to meet the needs of large-scale production. Currently, there are also devices on the market that use negative pressure suction nozzles to open bags. However, conventional negative pressure suction nozzles have the problem of unstable suction force, i.e., the packaging bag attached to the suction nozzle is easily detached, causing waste of packaging bags and pollution of the production environment.
