Quick-change type driving mechanism of paper indentation and trimming device

Abstract

The invention discloses a multifunctional quick-change type driving mechanism of a paper indentation and trimming device. A front fixed plate and a rear fixed plate are respectively arranged on the inner faces of a front wallboard and a rear wallboard; U-shaped blocking grooves are formed on the front fixed plate and the rear fixed plate; a front convex piece guide wheel and a rear convex piece guide wheel are respectively installed on the inner faces of the front wallboard and the rear wallboard; the front convex piece guide wheel and the rear convex piece guide wheel are respectively provided with a front convex piece and a rear convex piece which are respectively provided with a long circular groove; cam shafts which are driven by a motor are installed on the lower portions of the front wallboard and the rear wallboard in a cradle mode; each of the two cam shafts is provided with a front cam and a rear cam; a paper feeding upper rubber roller and a paper discharging lower rubber roller which are driven by the motor are arranged on the upper portions of the front wallboard and the rear wallboard in a cradle mode; a transmission gear which is driven by the motor is installed on the front wallboard; a reversing plate guide wheel is installed on the inner face of the rear wallboard; reversing driving plates are sleeved outside the reversing guide wheel and the rear convex piece guide wheel; a return tension spring and a reversing connecting rod are connected with the reversing driving plate; the reversing connecting rod is connected with an iron core of an electromagnet; and a hall sensor I is installed on the upper portion of the front wallboard. The driving mechanism is used for paper indentation and paper trimming.

Description

Background technique [0001] With the rapid development of the digital express printing industry, the amount of subsequent paper processing is increasing, and the processing requirements are getting higher and higher. For example, book covers, greeting cards, postcards, nameplates, invitations, tickets, etc. need creasing, dotted lines, trimming, horizontal cutting, vertical cutting, etc. Some thicker paper must be creasing before folding to ensure folding the quality of. [0002] The cover of the book, especially the book cover with exquisite binding, needs to process multiple indentation lines, such as the indentation line on the spine, the indentation line on the open line, the indentation line on the side edge, and the indentation line on the spine. In order to bulge upward, the indentation line of the opening line is convex downward, and the indentation line of the hemming is convex upward, which requires the processing of indentation lines in two directions, also known a...

Problems solved by technology

The usual method of creasing in two directions is: after the creasing in one direction is completed, the paper is turned over and creased again. The disadvantage of this is that the paper needs to be positioned twice when it enters the creasing machine. The positioning error of the paper and after a single creasing The deformation of the paper directly affects the error of the distance between the creasing lines

[0003] At present, there is no paper processing equipment with quick-change components, and both creasing, slitting, and cross-cutting on the market, especially paper processing equipment with bidirectional creasing function, and there is no corresponding report.
