[0070] refer to Figure 7 , in the first embodiment, the cutter group of the paper cutter includes a five-component cutter group, which is divided into the first, second, third, third, and fifth slitting knife groups from right to left, and the first slitting knife group The second, third, fourth, and fifth slitting knife groups all use amplitude-modulated slitting knife groups. The first slitting knife group is not equipped with X-axis precise displacement devices for the workbench. , the rest of the structure is the same as the amplitude modulation cutting knife group.

[0071] In this embodiment, the openable and closable connection device is adopted as a group of connection devices connected to the docking base 19 through the docking cylinder rod 17 of the docking cylinder 18; the docking cylinder 18 and the docking base 19 are respectively installed on On the two cutter assemblies of the cutter group; the docking cylinder 18 can be installed on the active knife shell 10,...

[0092] refer to figure 1 , Figure 8 , as a variant of the present invention, in the second embodiment, the slitting knife group is divided into the first slitting knife group, the second slitting knife group, the third slitting knife group, and the fourth slitting knife group; wherein, The first and fourth slitting knife groups are fixed slitting knife groups, and the second and third slitting knife groups are amplitude-modulated slitting knife groups.

[0093] The first slitting knife group is fixedly installed at the beginning of the grating ruler 22; the first slitting knife group does not have a grating reading head 23; the displacement of the driven knife face of the first slitting knife group relative to the laser sensor measuring point is S 1 ;The X-axis width from the laser sensor measurement point of the first slitter group to the zero point of the grating ruler is L 1 , L 1 is a fixed width;

[0094] The second slitting knife group is an amplitude modulation sli...

Abstract

The invention relates to a working method of a breadth-adjustable paper cutter knife set. A target displacement Xi of a cutter worktable is calculated through a driven cutter surface displacement Si,an actual displacement Xi' of the cutter worktable, a width Di of a driven cutter surface displacement measuring point corresponding to a displacement sensor measuring point of the cutter worktable and a target breadth Ai; and then, the cutter worktable moves to the target displacement place to finish adjustment of the cutting breadth. After the cutter setting is needed after cutters are worn, tiny displacement in cutter setting is detected through sensors arranged on the side surfaces of driven cutters to compensate into a control system to correct cutter position data stored in the system, so that the cutter setting is accurate. Through the actions, the purposes of automatically detecting the displacement, adjusting the breadth and finally liberating labors can be achieved.

Description

technical field [0001] The invention relates to a paper cutting device, in particular to a working method of a paper cutting machine knife group with adjustable width. Background technique [0002] In the prior art, there are usually multiple slitting knives arranged opposite to each other on the paper cutter. During the production process, the distance between the slitting knives needs to be adjusted according to the width of the paper to be produced. And the slitting knife of the paper cutter is generally slidably arranged on the slide rail, and when adjusted to the desired position, it is fixed by a fastener. When adjusting the slitting knife, it needs to be adjusted manually, and sometimes it needs to be adjusted repeatedly, which is time-consuming and laborious, and the accuracy is relatively unstable. Contents of the invention [0003] In order to solve the above-mentioned time-consuming and labor-intensive problems of manual movement and knife setting, and unstabl...
