Plastic bag packer

Abstract

The invention discloses a plastic bag packer used for packing low-cost plastic bags produced by a bag making machine. The plastic bag packer mainly comprises a rack, a feeding device, a support plate swinging device and a lifting sucking disc device, and is characterized by further comprising a bag conveying device and a bag making device; the bag making device is characterized in that an output mechanism is used for inputting package films on film rolls to the operation position of a thermal sealing mechanism and the operation position of a cutting mechanism, then the package films are thermally sealed and cut to form package bags, the package bags are output to a bag storage disc of the bag conveying device; the bag storage disc is used for conveying the package bags to a predetermined operation position of the packer along with a bag-conveying operation mechanism; a suction disc is arranged on the bag storage disc, is used for fixing the bottom layers of open ends of the package bags, and cooperates with the lifting sucking disc to open the openings of the bags. The plastic bag packer has the advantages that the structure is simple and compact, the bags are fed and conveyed stably and reliably in sequence, the technical problem that the bags are taken unstably in sequence of the plastic bag packer in the prior art is solved, the plastic bag packer also has a function of automatically making the bags, and the package cost is saved.

Description

technical field [0001] The invention relates to a packaging machine. Specifically, it is a plastic bag packaging machine that wraps plastic bags with packaging bags. Background technique [0002] The utility model relates to a plastic bag packing machine, which is used for packing the cost plastic bags produced by the bag making machine into the packing bags, so as to facilitate storage, sale and use. Application publication number CN103935567A, published on July 23, 2014, discloses a plastic bag folding and packaging machine (hereinafter referred to as reference document 1), which mainly includes: a folding and loading device, an opening device, and a clamping and output device. Application publication number CN104003027A, published on August 27, 2014, discloses an automatic bagging device for plastic bags (hereinafter referred to as reference document 2). It mainly includes bagging device, bag clamping device, bag supporting device, lifting pallet, bag lifting tray and l...

AI Technical Summary

Problems solved by technology

But the problem caused by this is: the suction plate swings above the bag storage tray. When absorbing the top packaging bag in the storage bag tray, due to electrostatic adsorption, repeated bag extrusion, etc., the gap between the packaging bags will be caused. Adhesion between them, sometimes two or more bags will be sucked up at one time

The problem is that, firstly, it can be clearly seen from the drawings disclosed in comparative documents 1, 2, and 3 that the left side of the bag opening device of the plastic bag packaging machine is provided with a lifting pallet and a supporting plate device, and a bag making device cannot be installed; There is an output device on the upper right side, and the place where the bag making device can be installed is only in the narrow L-shaped space below the output device

However, the bag-making device of the prior art is complex in structure, bulky, and high in cost, so it is difficult to match it.

Second, the packaging speed of the plastic bag packaging machine is fast and the action is complicated

Third, the packaging bag made by the bag making device is light in weight and easy to drift. It is difficult to fix the packaging bag immediately after ou
