Vertical folding mechanism of folding machine

Abstract

The invention discloses a vertical folding mechanism of a folding machine. The vertical folding mechanism of the folding machine comprises a paper folding part, a sensor and a guide part, wherein the sensor is arranged on one side of the paper folding part; the sensor is used for detecting the position of graph paper to limit the stroke of a servo motor; the guide part comprises a first baffle and a second baffle; the first baffle and the second baffle are arranged between the paper folding part and the sensor; the guide par plays a guiding role in guiding the graph paper. By applying the vertical folding mechanism of the folding machine, the folding line position of the graph paper is accurate.

Description

technical field [0001] The invention relates to a vertical folding mechanism of a folding machine. Background technique [0002] Folding machine is a machine specially used to fold printed and copied large-format drawings into specifications for archiving. Folding machines in the prior art generally include a horizontal folding mechanism and a vertical folding mechanism. The horizontal folding mechanism is used to fold The large-format drawings are folded horizontally into the width of the archive specification, such as A4 size with a width of 210mm, and the vertical folding mechanism is used to vertically fold the horizontally folded drawings into a specified width, such as A4 size with a length of 297mm . [0003] The Chinese patent application with the application number 201310605621.8 discloses a vertical folding mechanism of a folding machine, which includes a driving roller, a passive roller, an upper auxiliary roller, a lower auxiliary roller and a belt. Between the...

[0003] The Chinese patent application with the application number 201310605621.8 discloses a vertical folding mechanism of a folding machine, which includes a driving roller, a passive roller, an upper auxiliary roller, a lower auxiliary roller and a belt. Between the auxiliary roller and the lower auxiliary roller, when the drawing is conveyed by the transverse conveying mechanism to the sensor that contacts the paper outlet of the transverse conveying mechanism, the controller controls the servo motor to drive the active roller to rotate forward for S distance according to the preset data, and then the controller Control the servo motor to drive the active roller to rotate in reverse, so as to press the crease on the drawing and fold the drawing. The vertical folding mechanism of the above-mentioned folding machine relies on the controller to control the rotation stroke of the servo motor to control the position of the crease on the drawing. However, the drawings often cannot be guaranteed to move synchronously with the rotation of the servo motor. After the driving roller is driven to rotate forward for S distance, the drawing cannot be transported to the predetermined position, so that the position of the crease on the drawing is deviated, making the position of the crease on the drawing inaccurate
