The two connecting plates 8 on both sides of the same conveyor belt 5 are fixedly connected, and each connecting plate 8 is fixedly connected to the corresponding sliding bar 7 on one side close to the pulley 4. The connecting plate 8 plays a role in limiting the pulley 4 without affecting the rotation of the pulley 4. The two connecting plates 8 limit the two corresponding pulleys 4 on the left and right, so that the two can move longitudinally stably and rotate synchronously. A first motor 9 that drives the transmission shaft 3 to rotate is fixedly installed on one of the first vertical plates 2. When the first motor 9 drives a transmission shaft 3 to rotate, the two conveyor belts 5 rotate synchronously to perform conveying work.

A first bidirectional threaded rod 11 is rotatably connected between the two second vertical plates 10. The first bidirectional threaded rod 11 threads through four connecting plates 8. A second motor 12 that drives the first bidirectional threaded rod 11 to rotate is fixedly installed on the second vertical plate 10 on the rear side. When the second motor 12 drives the first bidirectional threaded rod 11 to rotate, it can drive the two pairs of connecting plates 8 to move relative to each other, thereby adjusting the distance between the two conveyor belts 5.

The lower ends of the two push plates 25 extend to a position at the same height as the upper end surface of the conveyor belt 5. The lower ends of the two limiting blocks 26 are fixedly connected to the upper ends of the two push plates 25 respectively. The limiting blocks 26 and the limiting slide play a role in limiting the push plates 25. When the fourth motor 27 drives the second bidirectional threaded rod 24 to rotate, the two push plates 25 can be driven to move relative to each other, thereby facilitating the centering of the semi-finished plastic packaging products placed on the two conveyor belts 5 and ensuring the accuracy of the subsequent folding of the packaging.
[0022] The working principle of the present invention is as follows: According to the width of the semi-finished plastic packaging products to be folded, the second motor 12 is used to adjust the spacing between the two conveyor belts 5, so that the semi-finished plastic packaging products are placed on the two conveyor belts 5, so that they are driven by the first motor 9 to be transported to the right, and when they are located below the centering mechanism, the fourth motor 27 is operated to drive the two push plates 25 to move relative to each other, so as to center the semi-finished plastic packaging products on the conveyor belt 5, so that the semi-finished plastic packaging products are transported neatly by the conveyor belt 5, until they move below the folding mechanism and stop. Stop, at this time, the four folding plates 20 in the folding mechanism are adjusted according to the specifications of the packaging box to be folded to form a rectangular structure consistent with the size of the packaging box, and then the telescopic cylinder 14 uses the supporting plate 15 to lift the semi-finished plastic packaging product above, so that it contacts the four folding plates 20 above to be stamped and folded (the semi-finished plastic packaging product is pre-cut with creases, so it can be bent without heating), forming a standardized plastic box, and then the folding plates 20 are removed, so that the plastic box can be removed by moving it down with the supporting plate 15, and the folding work is completed.
