Technical Field
[0001] The utility model relates to a knotting mechanism, in particular to a multi-layer film punching and knotting mechanism. Background Art
[0002] At present, plastic bag packaging is widely used in the carton packaging and unpacking solutions of various tobacco factories. The outer layer of the pressed cigarette sheet stacks packed in cartons is covered with plastic bags. During the unpacking process, a special mechanism is used to cut the sealed packaging bag in the middle, and the robot grabs the packaging bag and places it in the material box. Because the packaging bag is relatively light and occupies a large space, the operators need to frequently handle the plastic bags in the material box, resulting in high work intensity, which is not conducive to the development of automated and intelligent work, affects the work efficiency generated by automation, and is prone to safety accidents.
[0003] There are two methods of plastic bag treatment that are being studied in the market. One is batch compression, which means that after a batch of packaging bags are accumulated in a material box, their volume is compressed by pressure, thereby achieving a longer processing time. Another method is roller crushing, which tears large plastic bags into small pieces and then collects them in the material box. Another method is hot melting, which collects the packaging bags and then uses the principle of heating to melt the plastic bags into blocks and then collect them in the material box. The above methods of plastic bag treatment are prone to generate waste and dust. Utility Model Content
