Automatic folding and rubber band bundling all-in-one machine for plastic bag

Abstract

The invention discloses an automatic folding and rubber band bundling all-in-one machine for a plastic bag. The automatic folding and rubber band bundling all-in-one machine for the plastic bag comprises a rack, a vibrating disc device, a rubber band opening device, a lifting handle folding device, a tail folding device and an inserting plate device. The automatic folding and rubber band bundlingall-in-one machine for the plastic bag is characterized in that the automatic folding and rubber band bundling all-in-one machine for the plastic bag further comprises a retreating clamping plate device and a conveying clamping plate device, the retreating clamping plate device and the conveying clamping plate device are used for oppositely folding and clamping one side of the plastic bag, the retreating clamping plate device loosens the plastic bag and retreats after the plastic bag is finalized, then one side of the plastic bag is clamped by the conveying clamping plate device, and the otherside of the plastic bag is inserted into the rubber band opening device to be bundled through relative motion of the inserting device. The automatic folding and rubber band bundling all-in-one machine for the plastic bag has the advantages that the processes from folding to bundling are almost conducted in the conveying clamping plate device and a clamping plate mechanism, integration of foldingand bundling is achieved on the condition that hand changing is not needed, therefore, the folding and bundling work is stable and reliable, and the structure is simple and compact.

Description

technical field [0001] The invention relates to an automatic folding and rubber band binding integrated machine for plastic bags, specifically a folding and binding machine that firstly automatically folds plastic bags, and then uses ring rubber bands to bind the folded plastic bags All-in-one device. Background technique [0002] The plastic bag of the present invention is a plastic convenient bag with two handles, also known as a vest bag. The plastic bags automatically produced by a bag making machine are generally dozens of plastic bags in a neat package. Put them together, and then transport them out one by one intermittently. In order to facilitate storage, sales and use, these plastics need to be folded several times. First, the two handles of the plastic bag are folded in the middle so that the two handles can cross together, and then the rear part of the plastic bag is folded two more times. to three times, and finally folded into a long strip, and then tied with ...

AI Technical Summary

Problems solved by technology

[0004] Its existing problems are: one, the handle position of the plastic bag is irregular, when a stack of plastic bags has been folded at least three times after passing through the handle folding device and the tail folding device, when the middle part is inserted When the plate press moves down at the predetermined folding line position, because the two handles have been folded to the middle once, and they are cross-folded together, and then folded again together with the front part of the plastic bag. The thickness of the plastic bag on the front side of the board is three times that of the plastic bag on the back side of the board

First of all, the space of the U-shaped transmission clip should not be too large. If the space is too large, the folded plastic bag will only have a V-shaped general outline and cannot form creases. Once released, it will rebound immediately. Strictly speaking, it has not been realized. Folding; and if the space of the U-shaped transmission clip is set smaller, then in the process of inserting the plastic bag by the plugboard, there will be a difference between the thickness of the plastic bags on both sides and the U-shaped transmission clip. The situation where the predetermined folding line deviates from the resistance

[0006] Thirdly, another problem in reference document 1 is: because the U-shaped transmission clip needs to be installed on the chain transmission mechanism, and multiple groups need to be set up, the structure is complicated

If a manipulator is designed to transfer between the folding device and the strapping device of the plastic bag, this will not only complicate the structure of the machine, but also reserve a certain movement space for the transfer path of the manipulator, which will also affect work speed and efficiency
