Description

Technical Field

[0001] The utility model relates to the technical field of valve bags, in particular to ultrasonic heat-sealing equipment for valve bags. Background Art

[0002] Valve bags, commonly known as paste-bottom bags, are currently popular international packaging bags. They are fed from the top or bottom valve port and use special filling equipment. After filling the materials, they are packed into cubes. The bags are neatly stacked and beautiful, and are environmentally friendly bags.

[0003] However, in the prior art, when the valve bag heat sealing device is working, the moving valve bag is in direct contact with the belt, which is prone to folding, resulting in unstable heat sealing quality and air leakage. In addition, the height of valve bags of different specifications is not always uniform and needs to be adjusted. For this reason, we propose an ultrasonic heat sealing device for valve bags.
