Full-automatic shaping packing machine of bag-in-bag

Abstract

The invention relates to a bag-in-bag full automatic forming packaging machine, applicable for the bag-in-bag full automatic forming package to repack an internal bag containing powder material in an external bag, which comprises a mechanical operation system, a mechanical transmission system and a control system. The mechanical operation system comprises an internal bag forming part, an external bag forming part and a double packaging part for bag-in-bag combination. The internal bag forming part comprises a cross break former, an internal bag forming head, an internal bag forming base, a further cross break pushing plate and a side-to-side break pushing plate, which enables the internal bag containing powder to be formed. After the external bag is formed with the cross break forming device, the internal bag is pushed into the external bag by a pushing plate of internal bag packing, and then the three side openings of the external bag are heat-sealed with a heat-sealer to form the bag-in-bag structure, thus the external bag forming part is formed. The invention has the advantages of high production efficiency, low cost, and hygiene and safety.

Description

technical field [0001] The bag-in-bag automatic forming packaging machine relates to a film bag packaging machine, especially an automatic packaging machine for packaging powdery materials in film bags, which is suitable for dividing powdery materials into small bags for packaging, and belongs to the field of packaging machinery . Background technique [0002] Plastic film bag forming and packaging machines are widely used in many industries, such as pharmaceutical, food, chemical and other fields. These industries need to use packaging machines to produce powder, crystal, flake, granular or The liquid product is made of plastic film (or low quality) into plastic bags such as square or rectangular or cylindrical, and the product is packaged into required specifications and weight for sale. [0003] Some powder products need to be double-packed to ensure their hygiene and safety, dust-proof and full utilization of the packaged objects. bag, forming a bag-in-bag double packa...

AI Technical Summary

Problems solved by technology

[0009] It can be seen from the above manual packaging process that each process is completed by manual operation, and the speed and production efficiency are very low. After testing, this manual bag-in-bag double packaging method can only complete 1 to 2 products per minute per worker. First, the production efficiency is low, and it is a simple repetitive labor, the labor intensity is high, and the workers are prone to fatigue.

It is also prone to pollution in the production process, and it is difficult to guarantee hygiene and safety, so there are great shortcomings and deficiencies
