Paper feeding mechanism of paper feeder and paper feeding method of paper feeding mechanism

Abstract

The invention discloses a paper feeding mechanism of a paper feeder and a paper feeding method. The paper feeding mechanism of the paper feeder comprises a paper separating device, a paper conveying device, a paper separating device height adjusting mechanism and a paper stack height real-time detecting and adjusting device, wherein the paper separating device is arranged above a paper feeding table, and the paper conveying device is arranged at a paper conveying station; the paper separating device height adjusting mechanism is arranged on a paper feeding head body and comprises a sliding guide assembly and an h proximity sensor; and the paper stack height real-time detecting and adjusting device is arranged below a paper conveying supporting plate and comprises a detection finger pushing mechanism, a detection finger lifting mechanism and an H proximity sensor. The paper feeding method of the paper feeding mechanism comprises the steps that when the paper is separated and conveyed, through the paper separating device height adjusting mechanism and the paper stack height real-time detecting and adjusting device, paper stacks with bent paper and warped paper can be automatically and reliably separated and stably conveyed, and good adaptability to the paper stacks is achieved; frequent shutdown of equipment is avoided, the working efficiency is improved, and the production cost is reduced; and the equipment is low in operation difficulty and low in labor intensity.

Description

technical field [0001] The invention relates to a paper feeding mechanism of a printing and packaging machine, in particular to a paper feeding mechanism of a paper feeder, and also relates to a paper feeding method of the paper feeding mechanism of a paper feeding machine, which belongs to the field of printing and packaging machinery. Background technique [0002] In printing and packaging equipment, the role of the paper feeder is to complete the continuous separation and conveyance of paper without damaging or polluting the paper, and for empty sheets that are separated and conveyed without paper, double sheets that are separated and conveyed by two sheets at the same time, and larger than Two sheets of paper are detected and controlled by multiple sheets of unqualified paper that are conveyed separately at the same time. The paper feeder is usually composed of a paper separating device, a paper conveying device, a paper feeding platform, a paper detection control device...

AI Technical Summary

Problems solved by technology

This is a supplement to the failure of the "wedge insertion" measure. Once the operator neglects to observe or fails to adjust the height of the paper separation device in time according to the warping and bending degree of the paper stack, there may be empty sheets, double sheets and multiple sheets. Waiting for unqualified paper, resulting in equipment downtime

[0005] Therefore, the defective that existing technology exists is, not only requires operating personnel to have higher professional technical quality and rich work experience, and the operation difficulty of equipment is big, and has strengthened the labor intensity of operating personnel, has increased the downtime of equipment, Reduce the operating rate of the machine, resulting in an increase in product costs and a decline in corporate competitiveness
