Description

Slitting cutter holder structure and slitting machine

Technical Field

The application relates to printing industry web product is cut, especially relates to a divide cutter holder structure and divide strip machine.

Background

The slitting machine is also called a slitting machine and is used for longitudinally slitting the strip-shaped printing paper and rewinding the slit narrow strips into rolls. The core of branch strip machine is cutting tool, cutting tool including divide cutter holder structure and with divide cutter holder structure shearing complex branch cutter blade structure, divide cutter holder structure include a length direction with the direction of delivery vertically blade holder roller of printing paper and follow the several sword base that blade holder roller length direction interval set up forms the sword groove between every two adjacent sword bases, divide cutter blade structure include with the cutter base one-to-one complex divides cutter blade. Referring to fig. 1, fig. 1 shows a mating structure of one of the cutting blades 101 and the corresponding first and second blade mounts 102 and 103. In fig. 1, it can be seen that the knife slot 104 is formed between the first knife base 102 and the second knife base 103, and the width of the knife slot 104 is matched with the thickness of the cutting blade 101 and is slightly wider than the thickness of the cutting blade 101. Among the adjacent first and second blade bases 102 and 103, the edge angle between the side surface and the top surface of the second blade base 103 adjacent to the first blade base 102, which is not in shear fit with the slitting blade 101, is 90 degrees. After the printing paper is cut by the slitting blade 101 due to the small-width knife slot 104 and the 90-degree corner angle, the slitting paper 105 on the second knife base 103 is pressed downwards by the slitting blade 101 and attached to the corner angle, the corner angle enables the corresponding part of the slitting paper 105 to generate a crease part 106 with the width of about 3cm, and the current processing method is to cut the crease part 106 again to guarantee the flatness of each slitting paper and guarantee the qualification rate of each slitting paper.
