[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a crease-forming device for producing composite packaging bags, comprising a crease-forming device housing 1, a guide plate 2 fixedly connected to the front of the crease-forming device housing 1, a feeding roller 3 disposed inside the crease-forming device housing 1, an internal guide roller 4 disposed inside the crease-forming device housing 1, a mounting support 5 disposed inside the crease-forming device housing 1, a crease assembly disposed inside the crease-forming device housing 1, a mounting support plate 903 fixedly connected to the crease-forming device housing 1, a rotating shaft 904 rotatably connected inside the mounting support plate 903, an adjusting gear 905 fixedly connected to the rotating shaft 904, a first toothed plate 906 slidably connected to a fixed slider 908 inside the mounting support plate 903, a first fixing plate 909 fixedly connected to a second toothed plate 907, a second fixing plate 910 fixedly connected to the first toothed plate 906, and a fixed connecting plate 909. A fixed slider 908 connected to the second toothed plate 907, and the first toothed plate 906 meshing with the second toothed plate 907 are connected to the adjusting gear 905. The fixed slider 908 slides inside the mounting support plate 903. The guide plate 2 guides the creased packaging bag, the feeding roller 3 fixes the packaging bag to be creased, and the guide roller 4 guides and conveys the packaging bag. The sliding of the second fixed plate 910 drives the first toothed plate 906 to slide inside the mounting support plate 903 under the limitation of the fixed slider 908. The first toothed plate 906, in the condition of meshing with the rotating shaft 904, drives the second toothed plate 907 to slide inside the mounting support plate 903. The second toothed plate 907 pulls the first fixed plate 909 to move. The packaging bag is fixed by the compression of the first fixed plate 909 and the second fixed plate 910.

[0024] Please see Figure 4 - Figure 5In this embodiment, two mounting support plates 903 are provided, and the two mounting support plates 903 are symmetrically fixedly connected inside the housing 1 of the crease device. The two mounting support plates 903 make the first fixing plate 909 and the second fixing plate 910 more stable when fixing the packaging bag. The mounting support plate 903 has a groove corresponding to the fixed slider 908. The fixed slider 908 slides inside the groove. The groove inside the mounting support plate 903 corresponding to the fixed slider 908 limits the movement of the fixed slider 908 within the groove. The first fixing plate 909 and the second fixing plate... The first toothed plate 906 and the second toothed plate 907 are slidably connected inside the mounting support plate 903. The slidable connection of the first toothed plate 906 and the second toothed plate 907 inside the mounting support plate 903 makes it more stable when fixing the packaging bag. An air pump 901 is fixedly connected to the back of the crease device housing 1. A pneumatic telescopic rod 902 is fixedly connected to the output end of the air pump 901. The pneumatic telescopic rod 902 is fixedly connected to the second fixed plate 910. The air pump 901 drives the pneumatic telescopic rod 902 to push the second fixed plate 910 to slide inside the crease device housing 1.

[0025] Please see Figure 2 - Figure 3In this embodiment, the crease assembly includes a first motor 801 fixedly connected to the mounting support 5, a rotating rod 802 fixedly connected to the output end of the first motor 801, an adjusting rotating frame 803 fixedly connected to the rotating rod 802, a sliding limiting rod 804 slidably connected inside the mounting support 5, a first sliding seat 805 slidably connected to the sliding limiting rod 804, a second sliding seat 806 and a fixed connecting seat 807 fixedly connected to the sliding limiting rod 804, an adjusting bracket 808 disposed between the adjusting bracket 808 and the fixed connecting seat 807, a limiting mounting block 809 fixedly connected to the sliding limiting rod 804, a return spring 810 fixedly connected between the limiting mounting block 809 and the fixed connecting seat 807, and a first sliding seat 805 and a second sliding seat 806 fixedly connected to the sliding limiting rod 804. The crease block 811 on 06 is driven by the first motor 801 to rotate the rotating rod 802, which in turn drives the adjusting rotating frame 803 to rotate inside the mounting support 5. The adjusting rotating frame 803 pushes the adjusting bracket 808 to rotate and adjust. The mounting support 5 has a corresponding groove on the first sliding seat 805. The first sliding seat 805 slides inside the groove. The groove on the mounting support 5 corresponding to the position of the first sliding seat 805 makes the first sliding seat 805 more stable when sliding. There are two adjusting brackets 808, and the two adjusting brackets 808 are respectively set between the adjusting rotating frame 803, the first sliding seat 805, and the fixed connecting seat 807. The two adjusting brackets 808 make the fixed connecting seat 807 and the first sliding seat 805 more stable when adjusted.

[0026] During operation, the packaging bag is unwound by the feeding roller 3 and guided by the guide roller 4 to be positioned between the second sliding seat 806 and the first sliding seat 805. The first motor 801 drives the rotating rod 802 to rotate the adjusting rotating frame 803 inside the mounting support 5. The adjusting rotating frame 803 pushes the adjusting bracket 808 to rotate and adjust. The adjusting bracket 808 pushes the fixed connecting seat 807 to pull the sliding limit rod 804 to slide inside the mounting support 5. The sliding of the sliding limit rod 804 pulls the second sliding seat 806 towards the first sliding seat 805. The adjusting bracket 808 pushes the first sliding seat 805 to slide on the sliding limit rod 804, causing the first sliding seat 805 to move towards the second sliding seat 806, thus creating a crease in the packaging bag between the second sliding seat 806 and the first sliding seat 805. The sliding of the second fixing plate 910 causes the first toothed plate 906 to slide inside the mounting support plate 903 under the limitation of the fixed slider 908. With the first toothed plate 906 meshing with the rotating shaft 904, the second toothed plate 907 is driven to slide inside the mounting support plate 903. The second toothed plate 907 pulls the first fixing plate 909 to move. The packaging bag is fixed by the compression of the first fixing plate 909 and the second fixing plate 910.

[0027] Through the above steps, the sliding of the second fixing plate 910 drives the first toothed plate 906 and the second toothed plate 907 to fix the packaging bag by the first fixing plate 909 and the second fixing plate 910 under the condition of meshing connection of the adjusting gear 905. This solves the problem that the crease device in the production of composite packaging bags does not fix the packaging bag, which affects the appearance and performance of the packaging bag, increases production time and labor costs, and reduces production efficiency.
