[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This adjustable packaging equipment for producing plastic bags possesses high flexibility and adaptability. In actual use, starting the first servo motor drives the first lead screw to rotate smoothly, and the first moving block moves precisely accordingly, thereby achieving height adjustment of the temporary storage box. The ingenious design lies in the fact that the distance between the temporary storage box and the top plate can be precisely controlled according to the required packaging quantity. When packaging a small number of plastic bags, the distance between the two can be reduced to ensure that the depth of the temporary storage box is suitable; while in large-scale production, increasing the distance can meet the temporary storage needs of a large number of plastic bags, greatly improving the application capability of the equipment in different production scenarios.

[0016] 2. This plastic bag production equipment has an adjustable packaging capacity. The finished plastic bags are conveyed to the guide plate by the conveyor device and stacked in the temporary storage box under the guidance of a series of structures. The first cylinder pushes the folding insert plate to press down and fold the plastic bags so that they are folded and temporarily stored in the folding slot. The rubber bands that are put on the hanging rod in advance are tied by the second servo motor. Finally, the second cylinder pushes the push plate to push out the packaged plastic bags. The whole process is smooth and efficient, which greatly improves production efficiency, reduces labor costs, and effectively ensures the efficient operation of production.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Example 1, as Figures 1-3 As shown, a packaging device for producing plastic bags with adjustable packaging quantity is provided. A first servo motor 6 is detachably connected to the upper end of a top plate 3. A coupling is provided at the output end of the first servo motor 6. The output end of the first servo motor 6 passes through the top plate 3 and is detachably connected to a first lead screw 7 through the coupling. A guide rod 8 is welded to the lower end of the top plate 3. One first moving block 9 is threadedly connected to the outer surface of the first lead screw 7, and another first moving block 9 is slidably connected to the outer surface of the guide rod 8. A temporary storage box 10 is welded between the two first moving blocks 9. The inner diameter of the temporary storage box 10 is slightly larger than the outer diameter of the rectangular guide frame 5.

[0024] The first servo motor 6 is started, which drives the first lead screw 7 to rotate smoothly. The first moving block 9 moves precisely accordingly, thereby realizing the height adjustment of the temporary storage box 10. The ingenious part of this design is that the distance between the temporary storage box 10 and the top plate 3 can be precisely adjusted according to the required packaging quantity. When a small number of plastic bags need to be packaged, the distance between the two can be reduced to ensure that the depth of the temporary storage box is suitable. In large-scale production, the distance can be increased to meet the temporary storage needs of a large number of plastic bags.

[0025] Example 2, as Figures 1-4 As shown, a packaging device for producing plastic bags with adjustable packaging quantity includes a guide plate 4 welded to the upper end of a top plate 3, a rectangular guide frame 5 welded to the lower end of the top plate 3, a through groove identical to the inner circle of the rectangular guide frame 5 opened at the center of the top plate 3, a folding slot 12 welded to the lower end of a temporary storage box 10, a first support frame 13 welded to the upper end of the top plate 3, a first cylinder 14 detachably connected to the upper end of the first support frame 13, a moving plate 15 detachably connected to the output end of the first cylinder 14, a folding insert plate 16 welded to the lower end of the moving plate 15, and a second servo motor 17 connected to the bottom plate 1. The output end of the second servo motor 17 is detachably connected to the second lead screw 18 via the coupling. The second moving block 19 is threaded to the outer surface of the second lead screw 18. The U-shaped connecting plate 20 is welded to the upper end of the second moving block 19. Two sets of hanging rods 21 are symmetrically welded to one end of the U-shaped connecting plate 20. The second support frame 22 is welded to one end of the two support columns 2. The second cylinder 23 is detachably connected to one end of the second support frame 22. The push plate 24 is detachably connected to the output end of the second cylinder 23.

[0026] The finished plastic bags are conveyed to the guide plate 4 by the conveyor device and stacked in the temporary storage box 10 under the guidance of a series of structures. The first cylinder 14 pushes the folding insert plate 16 to press down and fold the plastic bag so that it is folded and temporarily stored in the folding slot 12. The rubber bands that are put on the hanging rod 21 in advance are tied under the drive of the second servo motor 17. Finally, the second cylinder 23 pushes the push plate 24 to push out the packaged plastic bags.

[0027] It should be noted that this utility model is a packaging device for plastic bag production with adjustable packaging quantity. In use, the device is moved until the guide plate 4 is flush with and in contact with the plastic bag conveying device. Then, the first servo motor 6 is started to drive the first lead screw 7 to rotate. At this time, the first moving block 9 will rotate with the start, causing the temporary storage box 10 to adjust its height. When adjusting the distance between the temporary storage box 10 and the top plate 3, the depth of the temporary storage box 10 can be adjusted according to the required packaging quantity. After the produced plastic bags are conveyed to the guide plate 4 by the conveying device, they will fall through the through-slot opened in the center of the top plate 3 under the guidance of the guide plate 4. Then, guided by the rectangular guide frame 5, they fall into the temporary storage box 10 and are stacked. After the plastic bags are stacked to be flush with the top plate 3, the conveying stops. Then, the first cylinder 14 pushes the moving plate 15 and the folding insert 16 downwards. When the folding insert 16 moves downwards, it presses down on the center position of the stacked plastic bags and, through the rectangular guide frame 5,... The through slot 11 presses the center of the plastic bag downwards, at which point the plastic bag will fold and be temporarily stored in the folding slot 12. Here, before packaging, the binding elastic bands have been pre-attached to the outer surface of multiple hanging rods 21. After the plastic bag is folded, the second servo motor 17 starts and drives the second lead screw 18 to rotate. At this time, the second moving block 19 will move the U-shaped connecting plate 20 along with the rotation of the second lead screw 18, which in turn can move the hanging rods 21 and the elastic bands attached to their outer surface. After moving to the folding slot 12, the elastic bands will be blocked. If the movement continues, the elastic bands will be pushed out from the outer surface of multiple hanging rods 21 under the blocking action of the folding slot 12. At this time, the elastic bands will elastically contract and bind the folded plastic bag. Then, the second cylinder 23 pushes the push plate 24 to move. After the push plate 24 moves into the folding slot 12, it will push the bound plastic bag out from the direction of the second servo motor 17, completing the packaging operation of the plastic bag.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
