Description

Integrated inner and outer bag packing machine

Technical Field

The invention belongs to the technical field of packaging, and particularly relates to an integrated inner and outer bag packaging machine.

Background

The existing automatic or semi-automatic packaging machines are various in types, and can be used for quantitatively packaging materials such as powder, grains, plastics and the like so as to be beneficial to storage and transportation.

Seeds are the reproductive system of seed plants and play an important role in continuing species. After the seeds are produced in the same year, the seeds are generally sown and used until the next year, and therefore, the seeds need to be packaged, or stored or sold.

The seed package comprises an inner bag package and an outer bag package, namely, the seeds are packaged into an inner bag, and then a plurality of inner bags packaged with the seeds are packaged together. The material feeding and inner bag forming of the existing inner bag packing machine are divided into a plurality of different processes, namely, an inner bag (not sealed) is firstly manufactured, then the manufactured inner bag (not sealed) is transferred to the lower part of a material feeding opening, and after the material feeding is finished, the inner bag is transferred to a sealing working section to seal the inner bag, so that the inner bag packing is completed. So put in the separation with inner bag preparation and material and set up and lead to packing inefficiency. The existing outer bag packaging is mostly single packaging step by step along a production line, and the packaging efficiency is low and needs to be improved. The most main existing inner bag package and outer bag package are two independent devices which are separately arranged, so that the overall packaging efficiency is low, and the occupied area is large.
