Manipulator capable of automatic folding and binding of plastic bag

Abstract

The invention discloses a manipulator capable of automatic folding and binding of a plastic bag. The manipulator comprises a one-fold manipulator, a two-fold manipulator, a three-fold manipulator, a four-fold manipulator, a tape winding manipulator, a tape feeding manipulator and a hot-cutting manipulator, wherein the one-fold manipulator, the two-fold manipulator, the three-fold manipulator, thefour-fold manipulator are arranged in parallel, and the one-time folding, two-time folding, three-time folding, four-time folding of the plastic bag folding is completed in sequence, the tape feedingmanipulator conveys a binding tape to the tape winding manipulator, the tape winding manipulator is used for winding the binding tape around the folded plastic bag for one circle, the tape feeding manipulator rotates reversely, the binding tape is tightened, and the hot-cutting manipulator is used for carrying out heat combination and cutting off the binding tape. The manipulator capable of automatic folding and binding of the plastic bag can produce the plastic bag with a single line or a double line, and the three-time folding or the four-time folding of the plastic bag can be chosen optionally; and the manipulator can independently be composed of the device of folding and binding of the plastic bag, the manipulator can also be the manipulator for a plastic bag producing robot, and the manipulator capable of automatic folding and binding of the plastic bag has the advantages of being simple, reliable, high in speed and capable of replacing manpower.

Description

technical field [0001] The invention relates to an automatic folding and binding device for plastic bags Background technique [0002] At present, the vast majority of flat-mouth plastic bags and vest plastic bags in China are manually folded and bundled. The increasingly high labor costs make factories hope to have automatic folding and strapping equipment for plastic bags, but there is no such equipment abroad, and only Shandong has one in China. Automatic folding and binding equipment for plastic bags produced by household patent technology This patent was proposed in 2007 (patent number CN101134377A) and related equipment was sold. After that, the inventor of this patent applied for a number of improvement patents of this patent until 2013. Patent number, name , the time is as follows: 201110081121.X, plastic bag automatic folding and binding machine 2011.03.25; CN102190102A, handle folding device of plastic bag automatic folding and binding machine, 2011.4.1; CN10304324...

AI Technical Summary

Problems solved by technology

As for the mention in the patent that "cannot adapt to the diversified needs of the market with nylon ropes and rubber bands..." it is a bit far-fetched. The actual situation is that it is good to tie it up, no matter what rope is used

Moreover, the horizontal push plate is used in the folding, which takes up the horizontal space and limits the function of the bag making machine for the double-line folding and binding equipment, which is not very ideal
