Description
Technical Field
The invention relates to a plastic bag bagging machine, which is mainly used for sequentially filling bundled plastic bags into a packaging bag in a row.
Background
In the production process of plastic bags, a bag making machine folds and bundles a stack of produced plastic bags, sequentially outputs a bundle of plastic bags, and then manually packs the bundle of plastic bags into a packaging bag (generally, a woven bag). The main problems in the process of filling the packaging bag are: after a row of bundled plastic bags are filled into the packaging bags, the plastic bags are irregularly scattered in the process of entering the bag bottom from the bag opening and cannot be orderly stacked according to a row of rows, so that the number of the plastic bags (the bundle number) which can be packaged in each packaging bag is greatly reduced. If the plastic bags are manually adjusted and stacked, the working efficiency is greatly reduced.
Disclosure of Invention
The invention provides a plastic bag bagging machine, which aims to solve the problems in the prior art.
The technical scheme of the invention is as follows: a plastic bag bagging machine is characterized by comprising a base, supports, bag supporting plates, a plastic bag limiting device and a plastic bag loading device, wherein the plastic bag loading device is used for loading a row of bundled plastic bags into a packaging bag; a plastic bag limiting device capable of sliding up and down is arranged on the bracket below the bag supporting plate and used for dragging the bottom of the first row of plastic bags; a plastic bag loading device is arranged above the bag supporting plate; when the plastic bag loading device loads a row of plastic bags of the packaging bag, the plastic bag limiting device moves downwards for the distance of the row of plastic bags until the packaging bag is filled with the plastic bags.
The invention has the advantages that: the two lifting rods are utilized to limit the descending position of a row of plastic bags, after a conveying device conveys a row of bundled plastic bags to the upper surfaces of two horizontal supporting plates, the supporting plates rotate by 90 degrees or synchronously move relatively in the horizontal direction, meanwhile, the upper pressing plate and the lower pressing plate move downwards to load a row of plastic bags into the openings of the packaging bags, and due to the limitation of the lifting rods, the first row of plastic bags stay at the upper part in the packaging bags; then the lifting rod moves downwards for the distance of one row of plastic bags, the first row of plastic bags move downwards synchronously, and then the second row of plastic bags are loaded on the first row of plastic bags until the packaging bags are filled. The plastic bags in a row can be neatly loaded, and the working efficiency is greatly improved.
