AI Technical Summary
In the existing technology, the position of plastic packaging bags during the bundling process needs to be manually operated. The inconsistent bundling positions of the plastic packaging bags inside the bundling machine lead to an unstable center of gravity distribution, affecting the stability and neatness of handling and storage.
Design a strapping device for producing thin-film plastic packaging bags. The device adopts a limit seat and baffle structure. The limit seat and baffle block the end of the plastic bag to keep the position of the straps consistent. The spacing of the baffles can be adjusted by screws and guide rods to adapt to bags of different sizes, thus achieving uniformity in the position of the straps.
This ensures consistency in the placement of plastic bag tie straps, improves the stability and neatness of handling and storage, and enhances market competitiveness.

The packaging bag high-efficiency folding and bundling machine includes a box body and a bundling machine. The surface of the box body is provided with a folding device. The folding device includes a first housing and a flap. The second half gear protruding part is movably connected to the through hole on the surface of the fixed block.
[0004] Although the above-mentioned device can reduce the time of pressing and bundling and improve the working efficiency of the device, in actual use, the position of the plastic packaging bag for bundling inside the bundling machine needs to be operated manually, which leads to inconsistent bundling positions of each bundle of plastic packaging bags when a large number of plastic packaging bags are bundled, resulting in a relatively dispersed distribution of the center of gravity of the stacked plastic packaging bags, which is unstable during transportation and storage and prone to collapse. The uneven bundling position makes the entire packaging look scattered and untidy, reducing market competitiveness. UTILITY MODEL CONTENTS

Drive blocks are fixedly installed at the end of each of the first and second stop pieces. Screw holes are formed in the interior of each drive block. Screws are screw-connected and installed in the interior of each of the two groups of drive blocks.
[0007] Preferably, the first and second stop pieces are symmetrically arranged about the central axis of the limiting seat, and each of the first and second stop pieces is a rectangular structure made of plastic material.
[0008] Preferably, the first baffle, the second baffle end are provided with two groups of guide holes, and the two groups of guide holes are inserted with guide rods, and the two groups of guide rods are fixedly arranged on the inner wall surface of the limiting seat.
[0009] Preferably, the limiting seat is a 'U' shaped structure made of plastic material, and two groups of mounting holes are formed in the bottom of the limiting seat.
[0010] Preferably, the rotating shaft of the screw rod is fixedly connected with the adjusting wheel through the side wall of the limiting seat, and the screw rod and the guide rod are arranged in parallel.
[0011] Preferably, the adjusting wheel is a cylindrical structure made of plastic material, and a plurality of stress strips arranged at equal intervals are uniformly fixed on the outer surface of the adjusting wheel.
[0012] Compared with the prior art, the beneficial effects of the utility model are that: the end of the bundled plastic bag is arranged between the first baffle and the second baffle and is blocked by the limiting seat, so that the positions of the bundled plastic bags on the plurality of bundled plastic bags are kept consistent, the center of gravity of each plastic bag is similar, and the plastic bags are more stable and safe during carrying and storing; the uniform and tidy position of the tie makes the whole package look more standardized and clean, and gives a good visual experience; and the utility model is helpful to enhance market competitiveness.
