Bag taking and expanding equipment for packaging bags and bag taking and expanding method thereof

Abstract

The invention discloses bag taking and expanding equipment for packaging bags and a bag taking and expanding method thereof, and belongs to the field of packaging equipment. The bag taking and expanding equipment comprises a bag taking device, a bag expanding device and a bag opening fixing device; the bag taking device comprises a platform, a transmission belt end point in the vertical directionis arranged below the platform, a product transmission belt is arranged behind the bag taking device, and a discharging opening and the bag opening fixing device are arranged above the product transmission belt; the bag taking device comprises a bag clamping push-pull mechanism, a bag pressing mechanism, a bag dividing horizontal bar, a bag taking device mechanism and a pressing bar mechanism; thebag expanding device comprises a bag expanding mechanism and a bag expanding rotating mechanism; and the bag expanding fixing device comprises a bag opening clamping plate mechanism, a bag opening tensioning mechanism and a packaging bag baffle mechanism. The stacked packaging bags can be separated accurately, the bag falling phenomenon in the bag taking process can be prevented, the displacementphenomenon of the packaging bags on the lower layer can be avoided, wrinkles, folding corners and the like of the packaging bags can be flattened, bag openings are parallel to the rear end of a bottom plate while the packaging bags are flattened, the failure rate can be reduced, the energy consumption can be reduced, and the production efficiency can be improved.

Description

technical field

[0001] The invention relates to a bag taking and stretching device and a bag taking and stretching method thereof, in particular to a bag taking and stretching device for a packaging bag and a bag taking and stretching method thereof, belonging to the field of packaging equipment. Background technique

[0002] In the production of traditional industrial products, powdery and granular products are generally packaged in woven bags. The bagging of these products was almost done by hand. Since most of the bagged products are powdery products, they are highly polluting, Dust waves and other characteristics will bring some negative effects to the health of operators, and the labor intensity is high, so the mobility of operators engaged in this area is very high.

[0003] In recent years, with the development and growth of my country's industrial production scale, the cost of human resources has gradually increased, and some equipment has appeared to replace manual ...
