Discharge device of plastic bag folding machine

Abstract

The invention discloses a discharge device of a plastic bag folding machine. The discharge device of a plastic bag folding machine is mainly used on a plastic bag folding machine, including a frame, a head folding device, and a tail folding device. It is also provided with a lifting platform mechanism and a plurality of conveyor belt mechanisms, and the multiple conveyor belts are arranged side by side at intervals, and there are gaps between adjacent conveyor belts, and the folding platform is connected to the lifting mechanism. Driven by the lifting mechanism, the folding platform can reciprocate up and down from the gap. When rising, the folding platform completes the folding work together with the first folding device and the tail folding device. When falling, it can retreat into the gap. The folded plastic Bags are stranded and discharged onto a conveyor. The invention has simple structure and stable and reliable discharge operation.

Description

technical field [0001] The invention relates to a discharging device of a plastic bag folding machine. Background technique [0002] Dozens of stacks of rectangular double-layer plastic films produced on the bag making machine are punched by the punching device to form a plastic bag with two handles. In order to facilitate storage, transportation, sale, and use, these stacked plastic bags generally need to be folded multiple times, and finally folded into a rectangular shape, and then bundled or packed into packaging bags. The folding procedure is as follows: firstly, the handles of the two plastic bags need to be folded in the middle once, and then folded backward for the second time at the position of the second folding line. The applicant has also published a patent application with publication number CN102190102A titled "Handle Folding Device for Fully Automatic Folding and Binding Machine for Plastic Bags", and has also disclosed an authorized announcement number CN103...

AI Technical Summary

Problems solved by technology

And above-mentioned invention can only be bundled with plastic film, can't meet the diversified demands of market to strapping method and strapping material; And after binding, some unqualified bags are not easy to be found and are bound inside, which will seriously affect the qualified rate of the product

[0005] There is another important issue: the country has implemented the "Plastic Restriction Order" since June 1, 2008, requiring the thickness of plastic bags to reach 0.025mm, which is an increase in thickness compared with the ultra-thin plastic bags on the market before. As much as three times, the thickened plastic bag has great elasticity when folded and is not easy to fold. Therefore, with the implementation of the plastic restriction order, the folding method of plastic bags has also changed.

When at least two gear rods 42 pressed the plastic bag on the conveyor belt 53 through the tooth plate gap 39 of the fixed tooth plate 31, the plastic bag would also wrap around the toothed bar 38 and compress it on the conveyor belt 53 , which will firstly cause multi-stage concave folds in the plastic bag, the folded plastic bag is distorted and uneven, and it is easy to mess up the folded plastic bag in the process of pulling out the tooth plate 31
