Servo side pressing and paper feeding machine

Abstract

The invention provides a servo side pressing and paper feeding machine which is characterized in that a paper feeding mechanism comprises a vacuum absorption variable-speed paper feeding mechanism and a vacuum absorption constant-speed side pressing and paper feeding mechanism; two side pressing wheels are installed on a side pressing and paper feeding wheel shaft arranged above a constant-speed paper feeding wheel in the middle, the gaps between the side pressing wheels and the constant-speed paper feeding wheel are smaller than the thickness of a paper board, and the distance between the two side pressing wheels is adjusted by moving on the side pressing and paper feeding wheel shaft. Under the control of a vacuum absorption servo variable-speed paper feeding mechanism control system, the entire delivery of the corrugated board is realized by accelerating the corrugated board at first, then moving with constant speed and decelerating to stop, and the delivery precision and the delivery efficiency of the paper board are increased. Because of the action of a vacuum bellow, the corrugated board is tightly absorbed on the paper feeding wheel and is transported forward by means of friction force. The side pressing and paper feeding wheel only has auxiliary side pressing action, the pressing action of the side pressing and paper feeding on the corrugated board is reduced, and the strength of the corrugated board can not be substantially reduced.

Description

technical field [0001] The invention relates to a paper feeding device for the printing, slotting and die-cutting processes in the corrugated cardboard processing process, which belongs to the technical field of corrugated cardboard production equipment, in particular to a servo edge feeder. Background technique [0002] In the subsequent processing of corrugated cardboard, the processed cardboard needs to be printed, slotted, and die-cut, and processed into carton boards of different specifications according to national standards to make it meet certain load-bearing and volume requirements. With the development of the industry, the requirements for dimensional accuracy and exquisite printing of corrugated boxes are getting higher and higher. Therefore, the requirements for the accuracy of carton printing machinery are also getting higher and higher. [0003] The working principle of the corrugated cardboard paper feeding device of the existing carton printing machine is: th...

AI Technical Summary

Problems solved by technology

Due to the mechanical cam structure control, the three sets of paper feeding rollers cannot convey the corrugated cardboard in the whole process, and the size of the conveyed cardboard cannot be guaranteed; due to the flattening effect of the upper and lower paper feeding rollers on the corrugated height, the strength of the corrugated cardboard is greatly reduced.
