Full-automatic material packaging production line based on sleeved type inner-outer bags and packaging method of full-automatic material packaging production line

Abstract

The invention discloses a full-automatic material packaging production line based on sleeved type inner-outer bags and a packaging method of the full-automatic material packaging production line. The full-automatic material packaging production line comprises a bag fetching and bagging rack, a bag storage table, a bag storage box, a bag clamping and expanding rack, a machine frame, a material platform, an automatic packaging scale, a belt conveyor, a heat-seal bottom plate and a bag sewing device, and further comprises a bag fetching mechanism, a bag arranging mechanism, a bag folding mechanism, a bag clamping mechanism, a bag opening adjusting mechanism, a bag opening mechanism, a bagging mechanism, a rotating mechanism, an outer bag protecting and conveying mechanism, another bag clamping mechanism, a bag expanding mechanism, a bag sealing mechanism, a discharge hopper powdered-sugar sealing device, an air squeezing mechanism, an inner bag transferring mechanism, an opening heat-seal mechanism, an opening cooling sealing mechanism, an outer bag suction cup mechanism, a mechanism for placing the inner bag into the outer bag, and a sewing guide device. By means of the production line, the inner film bag of the sleeved bags can be loaded with small granular materials and then subjected to opening heat-sealing, and opening of the inner film bag of the sleeved bags can also automatically be disposed into the outer woven bag opening. Therefore, the invention further provides an automatic packaging method using the full-automatic material packaging production line.

Description

technical field [0001] The invention relates to the mechanical technical field of packaging materials, in particular to a fully automatic production line for packaging materials with inner and outer bags and a packaging method thereof. Background technique [0002] In consideration of factors such as reducing production costs, moisture-proof, and preventing the inner bag from being damaged during the loading process after packaging, the powder materials currently used in industries such as sugar, food, feed, chemical, starch, medicine, fertilizer, and nano-calcium carbonate, In the packaging of pellets, bagging inner and outer bags are widely used as packaging bags. The inner bag of this kind of packaging bag is plastic film, the outer bag is woven bag or paper bag, etc., the inner bag and the outer bag are set in the outer bag in a detachable way, and the length of the inner bag is about 100mm longer than the length of the outer bag. [0003] Due to the particularity of su...

AI Technical Summary

Problems solved by technology

This production process requires a lot of labor, and in many industries such as fertilizer, feed, and starch industries, the working environment is very harsh, and dust, harmful gases, etc. are very harmful to human health.

In food, sugar and other industries, direct contact with the inner bag during manual packaging, there are food safety and hygiene risks
