Longitudinal cutting device of paper cutter and control method of longitudinal cutting device

Abstract

The invention relates to a longitudinal cutting device of a paper cutter and a control method of the longitudinal cutting device. The longitudinal cutting device of the paper cutter comprises a rack, an upper cutter device, upper control devices, a lower cutter device and lower control devices, wherein the upper cutter device comprises upper motors provided with upper encoders, an upper ball screw which extends perpendicular to a conveying direction of paper, and is fixedly arranged on the rack, upper nuts which are arranged on the upper ball screw and driven to rotate by the upper motors, upper shaft sleeves arranged on the upper nuts in a sleeving manner, and upper cutters which are fixedly arranged on the upper shaft sleeves and located above a paper surface; in a process that the upper nuts rotate relative to the upper ball screw, the upper shaft sleeves slide perpendicular to the conveying direction of the paper; and the upper encoders are used for detecting positions of the upper cutters and used for converting position data into a digital signal. The longitudinal cutting device of the paper cutter and the control method of the longitudinal cutting device are short in cutter adjustment time and high in adjustment precision.

Description

technical field [0001] The invention relates to a slitting device of a paper cutter and a control method thereof. Background technique [0002] In the prior art, a paper cutter usually has a plurality of upper slitting knives and lower slitting knives arranged oppositely. During the production process, the distance between each upper slitting knife and each lower slitting knife needs to be adjusted according to the size of the paper to be produced. The slitting knife of the paper cutter is generally slidably arranged on the slide bar of the paper cutter, and when adjusted to a desired position, it is fixed by a fastener. When adjusting the slitting knife, the operator first measures and determines the designated position of each cutting knife, adjusts each lower cutting knife to the designated position one by one, climbs up the machine and adjusts each upper cutting knife to the designated position. The adjustment process generally takes 6 to 10 minutes, and the cutting ac...

AI Technical Summary

Problems solved by technology

The adjustment process generally takes 6 to 10 minutes, and the cutting accuracy is ±0.5mm; the adjustment is inconvenient, and sometimes it needs to be adjusted repeatedly, and the knife holder is easy to be damaged
