[0042] The working principle and beneficial effects of this invention are as follows:

[0043] When cutting a stack of digitally printed products, the stack is placed on the machine tool. Two first telescopic drive components move closer together, causing two right-angle push plates to move closer and clamp the two corners of the stack. The first telescopic drive components then extend, moving the stack to below the cutter. One push plate near the outer push plate moves away, while the other push plate continues to move forward, bringing the inner side of the stack close to the outer push plate. The push plate then moves away, and the cutter cuts downwards. After the first cut, the outer push plate pushes outwards, pushing the printed product out of the cutting position, removing the cut-off portion. After the shredded paper is cleared away, a stack of printed materials needs to be rotated 90 degrees to cut the other side. Two right-angle push plates clamp the stack of printed materials again, and then two electric rotating shafts drive the two right-angle push plates to rotate, thereby rotating the clamped printed materials 90 degrees. After rotation, the printed materials are pushed back to a position close to the outer push plate. The outer push plate then moves to adjust the size, and the cutter cuts the other side of the printed materials again, completing the cutting of the printed materials. After cutting, the outer push plate pushes the printed materials out again and clears away the shredded paper. This achieves automatic adjustment of the printed material cutting, avoiding manual operation and improving operational safety. Attached Figure Description

[0061] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0062] Example 1

[0063] like Figure 1-15 As shown, this embodiment proposes a cutting device for digital printing, including a base 1, a machine tool 2, and a platform 3. The machine tool 2 is mounted on the base 1, and the platform 3 is mounted on the top of the machine tool 2. A cutting groove is provided at the bottom of the platform 3, and a liftable cutter 4 is provided at the top of the cutting groove at the bottom of the platform 3. An outward push plate 5 is horizontally telescopically provided on the inner side of the cutting groove at the bottom of the platform 3.

[0064] It also includes an adjustment mechanism, which includes,

[0065] The first mounting bracket 10 is mounted on the machine tool 2.

[0066] Two first telescopic drive components 11 are provided, and the two first telescopic drive components 11 are slidably mounted on the first mounting bracket 10 via electric slide blocks. The telescopic ends of the first telescopic drive components 11 face the side of the base 3.

[0067] Two right-angle push plates 13 are provided, each of which is rotatably mounted on the telescopic end of one of the first telescopic drive members 11.

[0068] The right-angle push plate 13 is mounted on the telescopic end of the first telescopic drive member 11 via an electric rotating shaft seat 12.

[0069] In this embodiment, when cutting a stack of digitally printed products, the stack is placed on machine tool 2. Then, two first telescopic drive members 11 move closer to each other, causing two right-angle push plates 13 to move closer and clamp the two corners of the stack of printed products. Then, the first telescopic drive members 11 extend, and the two right-angle push plates 13 move the stack of printed products to below the cutter 4. Then, one right-angle push plate 13 near the outer push plate 5 moves away, while the other right-angle push plate 13 continues to advance, so that the inner side of the stack of printed products is close to the outer push plate 5. Then, the right-angle push plate 13 moves away, and the cutter 4 is controlled to cut downwards. After the first cut is completed, the outer push plate 5 pushes outwards, causing the printed products to be pushed out of the cutter. The cutter 4 removes the scraps of paper after cutting. At this point, a stack of printed materials needs to be rotated 90 degrees to cut the other side. The two right-angle push plates 13 clamp the stack of printed materials again, and then the two electric rotating shaft seats 12 drive the two right-angle push plates 13 to rotate, thereby causing the clamped printed materials to rotate 90 degrees. After the rotation is completed, the printed materials are pushed to a position close to the outer push plate 5. Then the outer push plate 5 moves to adjust the size, and the cutter 4 cuts the other side of the printed materials again, thus completing the cutting of the printed materials. After the cutting is completed, the outer push plate 5 pushes the printed materials out again and removes the scraps of paper. This realizes the automatic adjustment of the cutting of printed materials, avoids manual operation, and improves the safety of operation.

[0089] The shredder disposal mechanism further includes a twisting component, which includes...

[0090] Two first vertical plates 21 are provided, and the two first vertical plates 21 are installed on the top of the mounting horizontal plate 20.

[0091] Two torsion spring pivot seats 22 are provided, and the two torsion spring pivot seats 22 are respectively installed on the opposite sides of the two first vertical plates 21.

[0092] A rotating shaft 23 is mounted between the rotating shafts of the two torsion spring rotating shaft seats 22.

[0093] There are two second vertical plates 24, both of which are fixedly connected to the rotating shaft 23. The actuating plate 25 is fixedly connected to the two second vertical plates 24.

[0094] There are two second mounting plates 30, each fixedly attached to one of the two second vertical plates 24.

[0095] A connecting shaft 31 is fixedly connected between two second mounting plates 30.

[0096] There are two linkage rods 32, and the first ends of the two linkage rods 32 are rotatably connected to the connecting shaft 31.

[0097] Two limiting slide rails 35 are provided and fixedly connected to the flow guide baffle 15.

[0098] Two limiting slide blocks 34 are provided, and the two limiting slide blocks 34 are respectively slidably disposed in the two limiting slide rails 35.

[0099] There are two connecting shaft seats 33, which are respectively installed on the two limiting slide seats 34, and each connecting shaft seat 33 is rotatably connected to a linkage rod 32.

[0100] The shredder cleaning mechanism also includes a limiting component, which includes a limiting rod 26 and a limiting vertical plate 27. There are two sets of limiting rods 26, with two rods in each set. The two sets of limiting rods 26 are respectively fixed to the two side walls of the built-in mounting shell 14. There is a gap between the two limiting rods 26 in each set. There are two limiting vertical plates 27, which are respectively fixed to two second vertical plates 24. The bottom of the limiting vertical plate 27 is spaced from the top of the first vertical plate 21.

[0101] In this embodiment, after the printed product is cut once, the telescopic partition 9 will retract and open in advance, and the push plate 5 will push the printed product out to clean up its paper scraps. Then the printed product will be pushed towards the rectangular through slot of the telescopic partition 9, so that the cut side of the printed product hangs over the rectangular through slot. The hanging part is less than half the width of the printed product in that direction. Then the paper scraps of the printed product will fall from the rectangular through hole. During the falling process, the paper scraps will be collected by the wind to one side of the guide partition 15. Then the paper scraps will fall from the opening at the bottom of the inner mounting shell 14 and be collected by other containers.

[0102] After the shredded paper falls naturally, some of it gets stuck between adjacent sheets of paper during the cutting process. This causes some shredded paper to become trapped and unable to separate. At this point, the second lifting drive 16 is raised, causing the actuating plate 25 to move upwards. During this upward movement, the limiting vertical plate 27 moves upwards between the two limiting rods 26. Limited by the two limiting rods 26, the second vertical plate 24 and the actuating plate 25 remain vertical during the upward movement. In other words, the actuating plate 25 moves upwards, pushing one side of a stack of printed materials upwards, causing all the paper to rise. As the second vertical plate 24 bends, it drives the second mounting plate 30, connecting shaft 31, linkage rod 32, connecting shaft seat 33, and limiting slide 34 to move upward. That is, the limiting slide 34 moves upward in the limiting slide rail 35. The mounting horizontal plate 20 also drives the control rod 28 to move upward. When the bottom end of the limiting vertical plate 27 passes the two limiting rods 26, the limiting vertical plate 27 loses the support and restriction of the two limiting rods 26. At the same time, the limiting slide 34 moves to the top of the limiting slide rail 35 and can no longer move upward. At this time, the control rod 28 moves to the bottom surface of the wedge plate 29. The contact position is then determined, and the control rod 28 continues to move upward, moving along the inclined surface of the wedge plate 29 to the other side. This causes the mounting horizontal plate 20 to slide within the mounting slide rail 17 via the mounting slide block 19, compressing the first elastic element 18. The mounting horizontal plate 20 then causes the first vertical plate 21, torsion spring pivot seat 22, pivot rod 23, second vertical plate 24, and actuating plate 25 to move synchronously. However, due to the presence of the linkage rod 32, while the actuating plate 25 moves, the linkage rod 32 will pull the second vertical plate 24 and the actuating plate 25 through the second mounting plate 30 and connecting shaft 31. Then, the second vertical plate 24 will rotate through the rotating shaft 23 and the torsion spring rotating shaft seat 22, that is, the second vertical plate 24 and the actuating plate 25 will slowly tilt, that is, the actuating plate 25 will slowly move away from the printed product from bottom to top, and the bent paper will be pushed upward by the actuating plate 25. Starting from the first paper at the bottom, the paper will gradually leave the actuating plate 25 and pop downward, so that the paper will pop downward one by one. Then, the paper scraps stuck between the papers will fall out, realizing the intelligent separation of paper scraps stuck inside the paper, achieving a better paper scrap collection effect, and avoiding paper scraps remaining between the papers of the printed product.

[0103] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. 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.
