Plastic bags are easy to use and have become inseparable from our daily lives. For example, patent number CN202320096528.8 is a packaging bag cutting device, which has the following shortcomings:

[0003] The device cuts the packaging bag by providing a cutting mechanism, fixes the position of the packaging bag by providing a pressing mechanism, and flattens the packaging bag by providing a flattening mechanism.

[0044] Through the above-mentioned arrangement, the slide groove 7 is slidably connected to the slide rod 8, so that the slide groove 7 can slide smoothly on the surface of the slide rod 8 and drive the top plate 31 with the slide groove 7 to move in the through hole on one side of the upper surface of the shell 2, and the scale 5 can enable the top plate 31 to more accurately adjust its position in the through hole of the shell 2, and fix the top plate 31 through the first knob 6.

[0045] Reference Figure 2 , 3 4. A plurality of vertical cutting mechanisms 3 arranged in an array are arranged in the inner cavity of the shell 2, and the plurality of vertical cutting mechanisms 3 have not only the same structure but also the same installation method, and the vertical cutting mechanism 3 includes a top plate 31 slidably arranged on the inner surface of a through groove on one side of the shell 2, and the two sides of the lower surface of the top plate 31 are fixedly connected to the upper surfaces of two first vertical connecting rods 32, and a rotating shaft is penetrated at the lower part of the two first vertical connecting rods 32, and a through groove (such as Figure 3 As shown), the rotating shaft also movably passes through the upper parts of the two oblique connecting rods 34, so this rotating shaft connects the first vertical connecting rod 32 and the oblique connecting rod 34 together.

[0046] The inner surfaces of the lower parts of the two oblique connecting rods 34 are fixedly connected to the outer surface of the first blade guard 35, and are rotatably connected to the first cutting blade 36 inside the first blade guard 35. The middle parts of the two side surfaces of the first blade guard 35 are movably penetrated by the connecting shaft 37, and the middle part of the first cutting blade 36 is also movably penetrated by the connecting shaft 37. However, the middle part of the first cutting blade 36 has two outwardly protruding rings (such as Figure 4 As shown), the circular ring allows a certain distance to exist between the first blade guard 35 and the first cutting blade 36 to prevent friction between the first cutting blade 36 and the first blade guard 35, and one end of the two first springs 38 are fixedly connected to the surface of one side of the first blade guard 35 protruding on both sides of the connecting shaft 37, and the two first springs 38 are fixedly connected to the surface of one side of the two vertical support rods 33 at one end away from the connecting shaft 37, and a fixed round rod is fixedly provided on the upper part of the two vertical support rods 33, and the two vertical support rods 33 realize longitudinal reciprocating motion in the middle through groove of the first vertical connecting rod 32 through this fixed round rod.

[0048] Through the above arrangement, the friction wheel 310 rotates to drive the belt 311 to rotate, and the belt 311 rotates to drive the first cutting blade 36 to rotate. When the first cutting blade 36 rotates, the first blade guard 35 protects the first cutting blade 36, and also prevents the first cutting blade 36 from cutting the hands of the staff during replacement or other situations. The oblique connecting rod 34 and the first vertical connecting rod 32 cooperate to provide support for the first cutting blade 36 and the first blade guard 35, and the vertical support rod 33 can drive the guide rod 312 to adjust the distance between it and the lower surface of the inner cavity of the shell 2, so as to better guide the packaging bag, and the first spring 38 can limit the first cutting blade 36, and the top plate 31 can drive the entire mechanism to move in the inner cavity of the shell 2, adjust the channel width during cutting, and ensure the efficiency of packaging bag cutting.

[0049] It should be noted that the surface material of the friction wheel 310 is consistent with the surface material of the rubber-coated roller 13, so that the friction between the friction wheel 310 and the rubber-coated roller 13 can be better, and pointers are provided on the surface of the top plate 31 and one side of the scale 5, which can help people adjust the position of the entire device more intuitively.

[0052] Reference Figure 2 , 8One side surface of the outer shell 2 is fixedly connected to the one side surface of the motor box 12, and a servo motor 10 is fixedly arranged on one side of the inner cavity of the motor box 12, and the output end of the servo motor 10 is fixedly connected to the lower surface of the cable reel 9, and the lower end of the cable reel 9 movably passes through the upper surface of the motor box 12, and the wire groove surface of the cable reel 9 is fixedly connected to one end of the thin steel wire rope 44, and AC motor 11 is fixedly arranged on both sides of the inner cavity of the motor box 12 on the opposite side of the servo motor 10, and the output end of the AC motor 11 is fixedly connected to the one side surface of the rubber-coated drum 13, and the end of the rubber-coated drum 13 fixed to the AC motor 11 movably passes through the inner cavity side wall of one side of the outer shell 2, and the other end of the rubber-coated drum 13 is rotatably connected to the inner cavity side wall of the outer shell 2, and the outer surface of the rubber-coated drum 13 is in contact with the surface of the friction wheel 310 and can rotate with each other.

[0054] It should be noted that the cutting machine body 1, AC motor 11 and servo motor 10 are all prior art, and the control system required by the servo motor 10 can be set in the control system of the cutting machine body 1. Since the above structures are all prior art, they are not described in detail here.

[0055] The implementation principle of a packaging bag cutting device in an embodiment of the present application is: before cutting, the staff determines the size of the packaging bag, and then adjusts the top plate 31 by observing the scale 5 to make the first cutting blade 36 located at the position where the packaging bag needs to be cut, and then turns the first knob 6 to fix the top plate 31, and controls the frequency of the servo motor 10 through the controller, and then the AC motor 11 and the servo motor 10 are powered on.

[0056] The output end of the AC motor 11 rotates to drive the rubber coating roller 13 to rotate, and the packaging bag is brought into the inner cavity of the shell 2. Then the rubber coating roller 13 rotates to drive the friction wheel 310 to rotate. The friction wheel 310 rotates to drive the belt 311 to rotate. The belt 311 rotates to drive the first cutting blade 36 to rotate. When the packaging bag passes the lower part of the first cutting blade 36, the rotating first cutting blade 36 will cut the packaging bag.

[0057] At this time, the output end of the servo motor 10 rotates to drive the winding drum 9 to rotate, and the winding drum 9 rotates to reel the thin steel wire rope 44.
