[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. With the paper located inside the base, pull the squeezing frame upward within the two sets of moving plates. When the squeezing frame moves upward, it pulls the first spring connected to one end of the moving plate and the squeezing frame. The moving frame drives the two sets of moving plates to move within the convex groove. Adjust the paper cutting distance, release the squeezing frame, and use the reaction force of the first spring to push the squeezing frame against the paper.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please refer to Figure 1-4 As shown, this utility model provides a cutting device for a digital printing machine, including a base 1, with convex grooves 2 on both sides of the base 1, and movable plates 3 slidably connected inside the two sets of convex grooves 2, and extrusion frames 5 slidably connected inside the two sets of movable plates 3, with a first spring 4 connected to one end of each set of movable plates 3 and extrusion frames 5.

[0022] The bottom of the extrusion frame 5 is provided with a slide groove 6, and a moving block 7 is slidably connected inside the slide groove 6. A reset component is installed inside the moving block 7, and a cutter 10 is installed at the bottom of the reset component.

[0023] Specifically, with the paper located inside the base 1, the squeezing frame 5 is pulled upward within the two sets of moving plates 3. When the squeezing frame 5 moves upward, it pulls the first spring 4 connected to one end of the moving plate 3 and the squeezing frame 5. The moving frame 5 drives the two sets of moving plates 3 to move within the convex groove 2, adjusting the paper cutting distance. The squeezing frame 5 is released, and the reaction force of the first spring 4 pushes the squeezing frame 5 against the paper. The reset component installed inside the moving block 7 is pressed, causing the reset component to push the cutter 10 against the bottom of the base 1. The moving block 7 moves within the slide groove 6, allowing the cutter 10 to cut the paper.

[0024] The movable block 7 has a cavity 8 inside, and a lower pressure block 9 is slidably connected inside the cavity 8. The cutting blade 10 is installed at the bottom of the lower pressure block 9, and a reset component is installed between the cavity 8 and the lower pressure block 9. By pressing the lower pressure block 9, the lower pressure block 9 moves downward in the slide groove 8. The lower pressure block 9 drives the cutting blade 10 installed at the bottom to press against the bottom of the base 1 to cut the paper. The reset component installed between the cavity 8 and the lower pressure block 9 can drive the lower pressure block 9 to reset after moving, and the cutting blade 10 is retracted into the cavity 8.

[0025] The reset assembly includes a movable cavity 11, a movable plate 12, and a second spring 13. Two movable cavities 11 are respectively opened on both sides of the cavity 8. Two movable plates 12 are respectively installed on both sides of the lower pressure block 9 and are slidably connected in the movable cavity 11. Two second springs 13 are respectively connected between the movable cavity 11 and the movable plate 12. By pressing the lower pressure block 9 downward, the movable plates 12 installed on both sides move in the movable cavity 11. The movable plate 12 moves and stretches the second spring 13. When the pressing is released, the reaction force of the second spring 13 drives the movable plate 12 upward, so that the lower pressure block 9 is reset.

[0026] Wherein: magnets 14 are installed on both sides of the movable block 7, and magnet seats 15 are installed on both sides of the inside of the extrusion frame 5. The movable block 7 abuts against one end of the extrusion frame 4, and the magnets 14 installed on one side of the extrusion frame 5 are magnetically attracted to the magnet seats 15, thus fixing the movable block 7.

[0027] Among them: the bottom of the extrusion frame 5 is equipped with an anti-slip pad 16, which abuts against the top of the paper. The extrusion frame 5 drives the anti-slip pad 16 installed at the bottom to abut against the paper and prevent the paper from shifting.

[0028] Working Principle: This utility model provides a cutting device for a digital printing machine. During use, the paper is positioned within the base 1. Pulling the extrusion frame 5 upwards within the two sets of moving plates 3 pulls the first spring 4 connected to one end of the moving plate 3. The moving frame 5 then drives the two sets of moving plates 3 to move within the convex groove 2, adjusting the paper cutting distance. Releasing the extrusion frame 5, the reaction force of the first spring 4 pushes the extrusion frame 5 against the paper, pressing down the pressure block 9. The pressure block 9 moves downwards within the slide groove 8, simultaneously driving the two sets of moving plates 2... The movable plate 12 mounted on the side moves within the movable cavity 11. The movement of the movable plate 12 stretches the second spring 13, and the lower pressure block 9 drives the bottom-mounted cutting blade 10 to press against the bottom of the base 1. The moving block 7 moves within the slide groove 6, allowing the cutting blade 10 to cut the paper. Releasing the pressure utilizes the reaction force of the second spring 13 to move the movable plate 12 upward, causing the lower pressure block 9 to reset and retracting the cutting blade 10 into the cavity 8. Content not described in detail in this description belongs to the prior art known to those skilled in the art.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
