Plastic body folding machine

Abstract

The invention discloses a plastic folding machine which is used for folding plastic bags. The plastic bag folding machine comprises a rack, a plastic bag conveying device, a handle folding device, a final folding device, a clamping plate device, and a discharge output device. Piles of plastic bags produced on a bag making machine are conveyed to corresponding processing positions through the conveying device. Handles of the bags are folded through the handle folding device, and then the plastic bags are folded through the final folding device and are conveyed into the clamping plate device. The clamping plate device rotates 90 degrees in a swinging mode and then moves onto a bag discharge device. The bag discharge device moves downward and is inserted into clearance of the clamping plate device so as to block or pinch the plastic bags. When the clamping plate device and the bag discharge device are in relative motion, the plastic bags are discharged onto an output device. Folding package of the plastic bags is finished after manual banding. The plastic folding machine can meet requirements of diversified markets of nylon cord banding, rubber band banding or plastic film packaging, and is simple in structure and capable of folding neatly.

Description

technical field [0001] The invention relates to a folding device for a portable plastic bag. Background technique [0002] Previously, the folding and binding process of the portable plastic bags produced by the bag making machine was done manually. The applicant once applied for an invention patent with the application number "200720151993.8" and the patent name "plastic bag folding machine", publication number: CN101134377. Attempt to implement a model that only folds plastic bags without bundling, but the folded bags tend to rebound and scatter during discharge, and cannot be reliably placed in the predetermined position. Afterwards, the applicant applied for an invention patent with the patent number "201110081121.X" and the patent name "Fully Automatic Folding and Binding Machine for Plastic Bags" and obtained authorization. The publication number is CN102167172A. This patent is to automatically bundle the folded plastic bags with plastic straps in the clamping device...

AI Technical Summary

Problems solved by technology

This patent is to automatically bundle the folded plastic bags with plastic straps in the clamping device and then discharge them, avoiding the phenomenon of unraveling during discharge. Although this invention basically automates the folding of plastic bags, the structure is complicated , the manufacturing cost is high, and the binding form is single, which cannot meet the diverse needs of the market that is tied with nylon rope, tied with rubber bands or packaged with plastic film.

Due to the different models and sizes of plastic bags, for some shorter plastic bags, it is not necessary and impossible to fold the tail. Plastic bags that have not been folded at the tail will be bundled with a plastic bag automatic folding and strapping machine. The tail is loose and upturned, and the binding heat sealing and cutting device is easy to burn the tail; there is another situation: the bag making machine will inevitably produce some unqualified products during the bag making process. It is not easy to be found after being bundled, and it is not easy to remove, which will seriously affect product quality and pass rate
