Servo side-pressing paper feeder

Abstract

The invention provides a servo side-pressing paper feeder. The servo side-pressing paper feeder is characterized in that a paper feeding mechanism comprises a vacuum suction speed-changing paper feeding mechanism and a vacuum suction constant-speed side-pressing paper advance mechanism; two side-pressing wheels are installed on a side-pressing paper feeding wheel shaft arranged above constant-speed paper feeding wheels in the middle; a gap with the width less than the thickness of a cardboard is formed between each side-pressing wheel and the constant-speed paper feeding wheels in the middle. The two side-pressing wheels can be moved on the side-pressing paper feeding wheel shaft for adjustment of the separation distance. Under control of a control system, the vacuum suction servo speed-changing paper feeding mechanism conveys corrugated boards in the mode of accelerating at first, then keeping a constant speed and finally decelerating and stopping, and the feeding accuracy and the feeding efficiency of the cardboards are improved. Due to vacuum air suction boxes, the corrugated boards are tightly attached to paper feeding wheels and conveyed forwards through friction force; the side-pressing paper feeding wheels only achieve the auxiliary side-pressing effect, and the flattening effect of the side-pressing paper feeding wheels on the corrugated boards is reduced, so that the strength of the corrugated boards will not be lowered substantially.

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.
