Printing and slotting machine with all-servo paper feed system in paper feed part

Abstract

The invention relates to a printing and slotting machine with an all-servo paper feed system in a paper feed part, which comprises a front edge paper feed unit and a paper feed unit, wherein the front edge paper feed unit comprises three servo motors which respectively and independently control a paper feed idler wheel group to rotate and a vacuum adsorbing box which is configured under the idler wheel group; the paper feed unit comprises a servo motor which controls a paper feed upper roller to run and a vacuum adsorbing box which is configured on the roller; all the servo motors are connected with a coder by leads; the coder obtains the linear velocity information of a paper feed lower roller which is connected with a main drive system in a meshing drive way by a coder gear which is connected with a drive gear in the meshing drive way and feeds back the linear velocity information to the respectively independent servo motors; the servo motors adjust respective rotating speed according to the linear velocity information so that the linear velocity of a respective idler wheel and the paper feed upper roller is always synchronous and consistent with the linear velocity of the paper feed lower roller; and the two vacuum adsorbing boxes are in charge of the adsorption function of paperboards of the two paper feed units. The invention solves various problems existing when the printing and slotting machine feeds paper at high speed.

Description

technical field

[0001] The invention relates to a packaging machine, in particular to a printing slotting machine with a full servo paper feeding system in the paper feeding part. Background technique

[0002] Printing slotting machine is a widely used packaging machinery, its main structure is as follows figure 1 As shown, it includes leading edge paper feeding unit 11, paper feeding unit 12, multiple printing units 13, slotting unit 14 and die-cutting unit 15, each unit works in a unified and coordinated manner under the action of power equipment and transmission mechanism, and jointly completes Feeding, printing, slotting and die-cutting of cardboard. The paper feeding part consisting of the leading edge paper feeding unit and the paper feeding unit is equipped with a full servo paper feeding system, which uses four independent servo motors to drive three sets of paper feeding rollers and a paper feeding bottom roller respectively; And two sets of vacuum adsorption boxe...
