Currently, in the packaging industry, single pouch packaging, dual bags, and triple bags do not meet the needs of actual packaging. Especially in the pesticide package industry, with several regulations issued by the ministry of agriculture, invisible components cannot be involved in pesticide packages, namely specific components of each component of a product in the pesticide package need to be clearly explained on an outer package, so that the components in the pesticide package are often required to be packaged independently, and the independent packages of different components are connected together to form a multi-bag product for convenient sale and convenient use by users. However, to achieve good results, actual pesticide products often contain more than three of multiple components, which puts packaging demands on four-pack or even more-pack products in the pesticide packaging industry.

In the prior art, a full-automatic soft bag packaging machine mainly comprises a film rolling and unwinding device, a forming and guiding device, a bottom sealing device, a vertical sealing device, a traction device, a shearing device, an automatic opening device, a trolley moving device, a filling device, a top sealing device and a bag grabbing mechanical arm. The main working process is as follows: the plastic roll film is unreeled by a roll film unreeling device, then is folded and formed by a forming guide device, and the vertical edges are heat-sealed at the vertical sealing device to form a conjoined bag body belt with an upward opening; the traction device is used for traction of the packaging bag belt in the bag making process to smoothly complete the bag making process; after bag making is finished, the connected bag body belts are cut into product packaging bags by a cutting device, and the product packaging bags can be cut into single packaging bags, double-linkage bags and triple-linkage bags according to the packaging requirements; then the cut product packaging bags move forward under the driving of a trolley moving device, and are filled by a filling device after the top opening is opened by an automatic opening device; and after filling, the top is sealed by a transverse sealing device, and finally, finished product blanking is completed by a bag grabbing mechanical arm and the finished product is grabbed out of the packaging machine.
