Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically to an anti-curling device for a printing slitting machine. Background Technology

[0002] In the printing industry, slitting is a crucial process. However, current slitting machines often experience curling of printed materials during the slitting process. This is primarily because the internal stress distribution of the paper changes during transport to the slitting machine, and factors such as the paper's own tension can also cause the edges of the printed material to curl upwards or downwards.

[0003] Curled printed materials not only affect subsequent finishing, packaging, and transportation processes, reducing production efficiency, but may also lead to quality problems such as wrinkles and scratches on the surface, affecting the aesthetics and quality of the printed materials. In existing technologies, some slitting machines use simple pressure roller devices to attempt to solve the curling problem, but the results are not ideal. The pressure roller pressure is difficult to control precisely; excessive pressure may damage the surface of the printed material, while insufficient pressure cannot effectively suppress curling. Furthermore, traditional devices cannot adaptively adjust to printed materials of different thicknesses and widths, resulting in poor versatility.

[0004] Therefore, it is necessary to invent an anti-curling device for printing slitting machines to solve the above problems. Utility Model Content

Furthermore, the leveling mechanism prevents wrinkles and curling on the surface of printed materials, improving subsequent cutting efficiency and printing results.

[0016] This utility model incorporates a tension adjustment mechanism, which allows the first motor to rotate the shaft and the fixed plate during use. The rotation of the fixed plate then drives the anti-curling roller to rotate, thereby adjusting the surface tension of the printed material in real time and preventing curling. This further improves the efficiency and effectiveness of slitting and printing. Attached Figure Description

The bidirectional lead screw 63 is rotatably connected to the inside of the sliding limiting groove 61 and its one end is fixedly connected to the output end of the second motor 62.

[0028] like Figure 3 As shown, in a preferred embodiment, the conveying mechanism 8 includes two mirror-arranged side plates 81.

[0030] Therefore, when in use, the operator first places the roll 33 with the printed material on the placement groove 32, then pulls the printed material out, passes it around the fixed roller 49, then through the tension adjustment mechanism 4, then through the fixed platen 73 and the sliding platen 75, and finally through the conveying roller 83 and the limiting roller 88 into the slitting machine.

[0031] Then, the operator turns the second handwheel 89 to drive the second adjusting screw 85 to rotate. The rotation of the second adjusting screw 85 drives the sliding block 87 to slide.

Then, the operator turns on the second motor 62 to rotate. The rotation of the second motor 62 drives the bidirectional lead screw 63 to rotate. The rotation of the bidirectional lead screw 63 drives the two sliding rods 71 ​​to move towards each other until both sides of the printed material are in contact with the baffle 76. At this time, the operator turns the first handwheel 77 to drive the first adjusting screw 74 to rotate. The rotation of the first adjusting screw 74 drives the sliding plate 75 to move until the sliding plate 75 and the fixed plate 73 are in stable contact with both sides of the printed material.

[0032] Then the operator turns on the third motor 82 to move the printed matter. During the conveying process, when the surface tension of the printed matter is low, the operator turns on the first motor 42 to drive the rotating shaft 43 to rotate. The rotating shaft 43 drives the fixed plate 44 to rotate. The rotation of the fixed plate 44 drives the anti-curling roller to rotate, thereby adjusting the surface tension of the printed matter in real time. Then, the leveling mechanism 7 can be used to level the printed matter during the conveying process to prevent the printed matter from curling and warping.
