Description
Technical Field
The invention relates to the technical field of non-woven fabric packaging equipment, in particular to a packaging opening device of a non-woven fabric packaging bag.
Background
The opening device of the packaging bag is arranged on the packaging machine and is used for sucking the upper layer and the lower layer of the opening part of the packaging bag, so that the packaging bag forms an opening cavity, a packaged object is filled in, the structure of the packaging bag is similar to an envelope, three-side sealing is carried out, the bottom layer of the opening end is longer than the upper layer by two and three centimeters, and a sealing tongue is formed so as to facilitate opening.
For a long time, attempts have been made to place the package in a package tray, and the tray cylinder drives the package tray up so that the sealing tongue is held against the flap. The upper and lower layers of the bag were then sucked open using a conventional vacuum chuck. But the problems are: if the packaging is carried out by using a plastic packaging bag, the plastic bag is thin and very flexible. When the vacuum sucker is pressed on the plastic packaging bag, vacuum can be formed between the suction nozzle and the packaging bag, but when the sucker is lifted slightly, the plastic packaging bag is easy to deform to form radial wrinkles, the sealing performance of the contact surface of the suction nozzle and the plastic packaging bag is damaged, air leakage is caused, the plastic packaging bag is easy to fall down, and the sucked success rate is not very high. Another case is: with the improvement of social progress and environmental awareness, packaging bags made of environment-friendly materials such as non-woven fabrics are increasingly popular with people, and the market demand is increased year by year, which is a necessary trend of market development in the future. However, the nonwoven fabric has a relatively rough surface and air permeability.
