High-precision paperboard transverse and longitudinal slitting machine

Abstract

The invention relates to paperboard slitting equipment, in particular to a high-precision paperboard transverse and longitudinal slitting machine. The high-precision paperboard transverse and longitudinal slitting machine comprises a longitudinal cutter assembly, a transverse slitting front cutter assembly, a transverse slitting rear cutter assembly, a second paper guide roller, a servo motor, a sensor and a programmable controller, wherein the transverse slitting front cutter assembly and the transverse slitting rear cutter assembly are arranged on the paper discharging side and the paper feeding side of the longitudinal cutter assembly respectively, the second paper guide roller is driven by the servo motor, the sensor is arranged at the paper feeding position of the second paper guide roller, the output end of the sensor is connected with the input end of the programmable controller, and corresponding output ends of the programmable controller are connected with the control end of the servo motor, the control end of a front cutter motor and the control end of a rear cutter motor respectively. The high-precision paperboard transverse and longitudinal slitting machine aims to achieve low waste of paperboard tailing, high working efficiency and high precision. Compared with the prior art, the high-precision paperboard transverse and longitudinal slitting machine has the advantages of being high in automation degree, capable of customizing the sizes of paperboards according to different requirements for small paperboards of customers, reducing material loss of paperboards, and meanwhile solves the problem that existing paperboard slitting machines are unsuitable for slitting narrow paperboards.

Description

technical field [0001] The invention relates to cardboard cutting equipment, in particular to a high-precision cardboard vertical and horizontal cutting machine. Background technique [0002] A cardboard slitter is a mechanical device that cuts wide paper or film into multiple narrow strips. A set of longitudinal cutter assembly is provided in the existing cardboard slitting machine, and the cardboard is longitudinally slit by the longitudinal cutter assembly when the cardboard is slitting. The existing cardboard slitting machine can only perform one-way slitting. To complete the longitudinal and transverse slitting of the cardboard, it is necessary to perform two slitting. The work efficiency is low and the manpower consumption is large; The length of the feeding direction of the slitting cardboard has certain requirements. If the length of the feeding direction of the cardboard is less than the distance between the center line of the cutter and the center line of the pape...

AI Technical Summary

Problems solved by technology

Although this patented technical solution solves the problems of low working efficiency and high manpower consumption of the cardboard slitting machine, it still has the following disadvantages: the waste of cardboard tailings is large, because the transverse paper cutting device cross-cuts the cardboard at the last knife , the paper guide roller must also carry out the necessary pressure on the paper, so the cardboard must have a sufficient length of trailing edge to ensure the accuracy of the last cardboard crosscut
