The front and feeding systems An online tube film packaging machine based on multi-mechanism coordinated control.

Background technique

At present, for filling and packaging of large bags of bulk materials weighing 3 to 10 kg, prefabricated bags are basically used for semi-automatic or manual filling and packaging. Generally, prefabricated bags are relatively thin and can only be filled and packaged manually. However, the main defects and disadvantages of the existing semi-automatic packaging methods of premade bags are: they can only bag according to fixed specifications of premade bags, and cannot change the bagging of multiple product specifications, and the bag opening qualification rate is not high. The lower the pass rate.

The basic process of semi-automatic packaging of premade bags is: manual bag placement - alignment - bag suction - bag opening - filling - sealing - output and other working steps. Its disadvantages are: because the premade bags are thin and smooth, in the manual bag placement process, a maximum of about 50 bags can be stacked at a time; in the alignment action, the thinner the hand-placed premade bags are, the harder it is to stack them neatly, requiring a longer period of time. The time required to line up the entire row increases auxiliary work time, and adjusting product specifications is both time-consuming and labor-intensive. There are also semi-automatic or manual filling and packaging of premade bags, which are no longer suitable for the precise and efficient work requirements of current intelligent equipment, let alone the full-process intelligent filling and packaging production line.

In order to adapt to the requirements of the entire intelligent filling and packaging production line, and to adapt to the online adjustment of bagging requirements of different specifications, we broke through the existing technology and innovatively proposed a method that inputs product specification data and centrally manages it through the PLC control system, cutting and making bags according to different specifications and sizes. , completely breaking through the prefabricated bag filling and packaging method. The length and width data of the tube film bag is input from the entire roll of film through the PLC control system, and the bagging process from cutting bag making to material filling and sealing is implemented according to the data, completing the process from bottom sealing, cutting, and bag opening A tube film packaging machine based on multi-mechanism coordinated control of filling, sealing and weighing actions.

It should be noted in this patent: The above-mentioned whole roll film uses a cylindrical plastic film without broken transverse lines and transverse sealing lines, which is used for packaging bulk materials. The use of this tube film packaging technology solution can accurately and efficiently complete material filling and packaging, thereby effectively improving the efficiency of bulk material bagging and effectively reducing labor costs in the manual or semi-automatic filling and packaging process of premade bags.
