Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting machines, in particular to a die-cutting machine with adjustable guide rollers. Background Art

[0002] The guide roller of the die-cutter is used to die-cut paper during the printing process in the printing industry. The guide roller on the die-cutter guides the paper to prevent wrinkles on the paper during the die-cutting process, thereby reducing the die-cutting quality of the paper. For example, an asynchronous feeding device for a die-cutter disclosed in Chinese patent literature (patent number: CN202121199069.3) guides the paper through a guide roller and a pressing roller. However, since the guide roller cannot flexibly adjust the gap between the guide roller and the pressing roller, the die-cutting quality of the paper is reduced during the die-cutting process of the die-cutting machine for papers of different thicknesses. For example, when die-cutting thin paper, the gap between the guide roller and the pressing roller is too large, resulting in a deviation in the guidance of the paper, which easily causes wrinkles on the paper and reduces the die-cutting quality of the paper.

[0003] For this purpose, we propose a die-cutting machine with adjustable guide rollers. Utility Model Content

When die-cutting papers of different thicknesses, The first guide roller 15 needs to be adjusted. Use a tool (such as a wrench) to rotate the first bolt 10. You only need to loosen the first bolt 10 without removing it. Then loosen the second bolt 18. At this time, rotate the adjusting rod 2. The adjusting rod 2 rotates up and down through the first bolt 10 to adjust the position of the first guide roller 15. At the same time, rotate the threaded rod 7. The threaded rod 7 cooperates with the first threaded hole 6 to push the fixed shaft 4 to slide in the slide groove 3. The fixed shaft 4 drives the first guide roller 15 to move and adjust the left and right position of the first guide roller 15. After the adjustment is completed, rotate the first bolt 10 and tighten the first bolt 10. Press the adjusting rod 2 directly on the fixing frame 1 and fix the adjusting rod 2 so that the distance between the first guide roller 15 and the pressing roller 17 is adapted to the paper to be die-cut. During the die-cutting process, the flatness of the paper is ensured without wrinkles, thereby improving the die-cutting quality of the paper.

[0018] The second threaded hole 8 is provided with a second bolt 18. When the second bolt 18 is tightened, the second bolt 18 cooperates with the second threaded hole 8, and the second bolt 18 presses against the side wall of the fixing frame 1, and at the same time exerts a reaction force on the adjusting rod 2, pushing the adjusting rod 2 outward, and cooperating with the first bolt 10 to press the adjusting rod 2, thereby fixing the adjusting rod 2;

[0019] Both ends of the second guide roller 16 and the pressure roller 17 are connected to the fixed frame 1 through shafts, and the shaft and the fixed frame 1 are connected through bearings. The second guide roller 16 and the pressure roller 17 rotate through the cooperation of the shaft and the bearings;

[0020] The left end of the fixed shaft 4 passes through the first guide roller 15 and is connected to the fixed frame 1, and the fixed shaft 4 is fixedly connected to the fixed frame 1, and the fixed shaft 4 is connected to the first guide roller 15 through a bearing. The first guide roller 15 rotates through the bearing;

[0021] A bearing is arranged between the left end of the threaded rod 7 and the fixed shaft 4. The connecting part between the threaded rod 7 and the inner ring of the bearing is not provided with threads. The left end of the threaded rod 7 is fixedly connected to the inner wall of the inner ring of the bearing. The threaded rod 7 drives the fixed shaft 4 to move left and right during the movement.

[0022] Working principle: When die-cutting papers of different thicknesses, the first guide roller 15 needs to be adjusted. Use a tool (such as a wrench) to rotate the first bolt 10. It is only necessary to loosen the first bolt 10 without removing it. Then loosen the second bolt 18. At this time, rotate the adjusting rod 2. The adjusting rod 2 rotates up and down through the first bolt 10 to adjust the position of the first guide roller 15. At the same time, rotate the threaded rod 7. The threaded rod 7 cooperates with the first threaded hole 6 to push the fixed shaft 4 to slide in the slide groove 3. The fixed shaft 4 drives the first guide roller 15 to move and adjust the left and right position of the first guide roller 15. After the adjustment is completed, rotate the first bolt 10 and tighten the first bolt 10. The limiting plate 14 set on the first bolt 10 cooperates with the limiting groove 13 to directly press the adjusting rod 2 on the fixing frame 1. Fix the adjusting rod 2 so that the distance between the first guide roller 15 and the pressing roller 17 is adapted to the paper to be die-cut. The flatness of the paper is ensured during the die-cutting process, and wrinkles will not appear, thereby improving the die-cutting quality of the paper.
