[0019] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0020] Embodiment:

[0021] like Figure 1-Figure 5 As shown, a packaging bag cutting device includes a packaging bag cutting machine 1, a crossbar ruler 2 is arranged inside the packaging bag cutting machine 1, a ring 3 is sleeved on the surface of the crossbar ruler 2, a knife 4 is sleeved on the surface of the ring 3, a packaging bag 5 is arranged inside the packaging bag cutting machine 1, the top end of the knife 4 penetrates the packaging bag 5 and is located outside the packaging bag 5, a fixing groove 14 is opened on the surface of the crossbar ruler 2, a card slot 13 is opened on the surface of the ring 3, a card block 6 is arranged inside the card slot 13, and a pull is arranged to connect the card block 6 and the card slot 13 Spring 15, one end of the card block 6 passes through the card slot 13 and is located inside the fixed slot 14, the surface of the collar 3 is sleeved with a knife 4, the surface of the collar 3 is provided with a limiting slot 10, the inner wall of the knife 4 is provided with a slide slot 11, the inner side of the slide slot 11 is provided with a spring 8, the top of the spring 8 is provided with a limiting block 7, the top of the limiting block 7 is located inside the limiting slot 10, the inner wall of the slide slot 11 is provided with a threaded groove 12, the bottom end of the spring 8 is provided with a screw 9, the bottom end of the screw 9 passes through the slide slot 11 and the threaded groove 12 and is located outside the knife 4;

[0022] When the existing packaging bag cutting machine 1 is rolling up the packaging bag raw material, the packaging bag raw material width is too long and needs to be cut and then rolled up. The cutting distance adjustment operation of the knife 4 is inconvenient, which easily leads to inconsistent width after cutting. By setting the cross bar ruler 2, when cutting, the card block 6 is pulled by pulling the pull ring. At this time, the tension spring 15 is stretched, and one end of the card block 6 slides out from the inner side of the fixed groove 14, and then the sleeve ring 3 is held and pushed to slide on the surface of the cross bar ruler 2. The position of the other fixed groove 14 is determined according to the centimeter scale numbers on the surface of the cross bar ruler 2, until the card block 6 is aligned with this fixed groove 14, the pull ring is released, and the tension spring 15 drives the card block 6 from the card groove 13 into the inner side of the fixed groove 14 to complete the preliminary positioning, and then the screw rod 9 is rotated. Under the action of the mutual group of threads, the screw rod 9 moves to the outside of the knife 4, releasing the extrusion of the spring 8 and the limit block 7, and the bottom end of the knife 4 is sleeved on the surface of the sleeve ring 3, which can push the knife 4 to move on the surface of the sleeve ring 3, and the knife 4 drives When the limit block 7 moves, the top end of the limit block 7 is squeezed by the limit groove 10, pushing the limit block 7 back to the inner side of the slide groove 11. At this time, the spring 8 is forced to shrink. When the limit block 7 reaches the next limit groove 10, the spring 8 pushes the limit block 7 from the slide groove 11 into the inner side of the limit groove 10. At this time, pushing the knife 4 again will have a certain resistance. Therefore, it can be determined that the knife 4 has reached a certain scale position. After adjusting the position of the knife 4 according to the millimeter scale mark on the surface of the collar 3, the screw 9 is rotated, and the screw 9 enters the inner side of the slide groove 11 from the thread groove 12 until the screw 9 squeezes the spring 8. The spring 8 squeezes the limit block 7, so that the limit block 7 cannot leave the limit groove 10, completing the final precise positioning; by setting the crossbar ruler 2 and the collar 3, the collar 3 is moved to adjust the centimeter degree, and then the knife 4 is moved to adjust the millimeter degree, so as to realize fast positioning adjustment, improve work efficiency, facilitate adjustment of any degree, and improve the applicability of the machine.
