[0020] Example: Refer to Figure 1-4 The utility model provides a packaging bag cutting machine, comprising a workbench 1, a pre-scaling material assembly is arranged on one side of the workbench 1, and the pre-scaling material assembly comprises a first support frame 8 arranged on the rear side of the workbench 1, a rotating wheel 9 connected to the upper end position of the inner side wall of the first support frame 8, a high foot frame 6 arranged between the first support frame 8 and the workbench 1, a second support frame 2 arranged on one side of the upper end of the workbench 1, a rotating member connected to the inner end of the second support frame 2 and a conveyor belt 3 arranged on the other side of the second support frame 2 away from the high foot frame 6;

[0021] The rotating member includes a motor 10 arranged on the outside of the second support frame 2, an active roller 11 connected to the output end of the motor 10, a first gear plate 12 arranged at the front end of the active roller 11, a second gear plate 13 rotatably connected to the upper end of the first gear plate 12, and a driven roller 14 connected to the rear side of the second gear plate 13.

[0022] Among them: the active roller 11 and the driven roller 14 have the same shape, and a rotating shaft is connected at both ends. When the electric spindle of the motor 10 rotates, the rotating shaft connected to the two ends of the active roller 11 can rotate relative to each other, and the rotating shaft drives the active roller 11 to realize its rotatable setting. At the same time, the driven roller 14 realizes a relative rotation process by utilizing the meshing rotation of the first gear plate 12 and the second gear plate 13. The same rotating shaft is set at both ends, which greatly improves the stability of the device structure.

[0023] Among them: a plurality of fixed columns 7 are evenly arranged at the same height at the inner end of the high tripod 6. This device can generate a certain contraction force when the packaging bag is conveyed by arranging a plurality of fixed columns 7 with the same equal spacing on the inner wall of the high tripod 6, so as to realize the compression and contraction effect on the packaging bag.

[0024] Wherein: it also includes a cutting assembly, which includes a fixed plate 4 fixedly connected to the front end of the rear side of the workbench 1, a connecting plate 15 connected to the upper end of the fixed plate 4, a first electric telescopic rod 16 arranged at the end position of the front end surface of the connecting plate 15, a slider 17 connected to the bottom end of the first electric telescopic rod 16, a second electric telescopic rod 19 connected to the front end of the slider 17, and a cutting knife 20 arranged at the front end of the second electric telescopic rod 19. The fixed plate 4 of this device can support and stabilize the upper end, and the connecting plate 15 arranged at the upper end can support and stabilize the first electric telescopic rod 16 and the second electric telescopic rod 19 on the surface. At the same time, under the action of the first electric telescopic rod 16, the second electric telescopic rod 19 can realize its lifting process to ensure that its cutting process is intermittent.

[0025] Among them: a slide groove 18 is opened at the front end of the connecting plate 15, and the slider 17 slides in contact with the slide groove 18. This device can slide in contact with the slider 17 connected to the slide groove 18 through the slide groove 18 opened on the surface of the connecting plate 15, which is convenient for improving the sliding stability of the device structure.

[0026] Wherein: a placing frame 5 is provided at the bottom of the front end of the workbench 1, and the upper end of the placing frame 5 is directly opposite to the front end of the conveyor belt 3. This device facilitates the collection and placement of the packaging bags after cutting through the placing frame 5 provided below the conveyor belt 3.

[0027] The working principle of the embodiment of the utility model is as follows: when in use, the packaging bag to be cut is placed on the rotating wheel 9, and the other end is wound between the driven roller 14 and the active roller 11, and the motor 10 is started. Under the rotation of the electric spindle of the motor 10, the active roller 11 at the output end can undergo a relative rotation process, and the first toothed disc 12 arranged at the front end of the active roller 11 rotates, thereby driving the second toothed disc 13 above which is relatively engaged to undergo the same rotation process, so that the relative rotation of the driven roller 14 can be realized, thereby driving the packaging bag placed between the active roller 11 and the driven roller 14 to move forward, and the packaging bag is conveyed to the front end by the conveyor belt 3, and the first electric telescopic rod 16 is extended downward to realize the sliding process of the slider 17 at the bottom on the slide groove 18 provided on the surface of the connecting plate 15, and the second electric telescopic rod 19 at the front end of the slider 17 can realize the relative downward cutting process of the cutting knife 20 at the top, so that the lifting and cutting process can be completed, and then it is conveyed to the placement frame 5 below one end by the conveyor belt 3, and the operation can be completed.
