Plastic bag bundling machine

Abstract

The invention discloses a plastic bag bundling machine. Plastic bags are bundled by adopting linear elastic rubber bands. The plastic bag bundling machine mainly comprises a rack, a pay-off device, abag transfer device, a connecting device, a cutting device and a doubling plate, wherein one end of a bundling line is fixed by a wire pulling clamp of the pay-off device; a pay-off valve reciprocatesrelative to the wire pulling clamp under drive of a pay-off driving mechanism so as to release one section of needed bundling line; the bag transfer device is used for transferring plastic bags to the rear of the connecting device by virtue of the pay-off device; the bundling line is wound on the plastic bags in a V shape in the transfer process, and after a pay-off mouth and the doubling plate move downwards, the bundling line further draws close, the connecting device is used for connecting two strands of bundling lines drawing close to form an O-shaped ring, the cutting device is used forcutting off positions of the bundling lines outside the connecting points, and the operation of bundling of the plastic bags is completed. The plastic bag bundling machine disclosed by the invention is simple in structure and high in efficiency.

Description

technical field [0001] The invention relates to a plastic bag binding machine, in particular to a binding device which uses a linear elastic rubber band as a binding line to bind folded plastic bags. Background technique [0002] The plastic bags produced by the bag making machine are generally placed on the pallet with dozens of bags as a stack. In order to facilitate storage, transportation, sales and use, these stacks of plastic bags generally need to be folded three or four times, folded into strips, and then tied with rubber bands in the middle of the folded strips of plastic bags . Authorized notification number CN102167172 B", discloses an invention patent called a fully automatic folding and binding machine for plastic bags (hereinafter referred to as reference document 1). The binding device involved in reference document 1 is mainly composed of a folding plate, a clamping device, Consisting of two belt feeding devices and a heat sealing device, plastic strips are...

AI Technical Summary

Problems solved by technology

The problems in comparative document 1 are: first, the binding method of comparative document 1 is to use two binding straps for binding, and there are two binding straps and two connecting points on the binding line of each plastic bag, and the more connecting points The weaker it is, and it also affects the appearance

Second, because the plastic strapping is almost inelastic, the strapping must be torn when opening the plastic bag, and once it is torn open, it cannot be bundled any more

Moreover, the binding procedure of Comparative Document 2 is cumbersome, and the structure of the binding device is complicated. It is necessary to prefabricate a rubber ring on the binding barrel, and then put the rubber ring on it, and then fix the plastic bag with a pressure plate after putting on the rubber ring, and then The bag passing manipulator is then pulled out to meet the next strapping procedure, which is inefficient
