Folding and bundling integrated machine for packaging bag

Abstract

The invention discloses a folding and bundling integrated machine for a packaging bag. The folding and bundling integrated machine comprises a machine frame, a bag body folding mechanism and a bundling mechanism, and is characterized in that the bag body folding mechanism comprises a supporting plate, a center positioning device, a front folding device for folding the bottom of a bag body backwards, and a rear folding device for folding a bag opening part of the bag body forwards. The front folding device and the rear folding device are arranged in front of and behind the supporting plate correspondingly. The center positioning device comprises positioning pressing plates, lifting parts driving the positioning pressing plates to rise and fall, and adjustment parts used for adjusting the transverse positions of the positioning pressing plates. The positioning pressing plates include the left pressing plate and the right pressing plate. The left pressing plate and the right pressing plate are arranged over the supporting plate and arranged on the two sides of the supporting plate correspondingly. Under the folding working condition, the bag body is arranged on the supporting plate, a front pressing plate and a rear pressing plate. According to the folding and bundling integrated machine, folding of the bag body is achieved in a center positioning and frontward-backward folding manner, the structure is simple, the machining cost is low, and the bag body folding efficiency is high.
