Horizontal folding mechanism of folding machine

Abstract

The invention provides a transverse folding mechanism of a drawing folding machine. The transverse folding mechanism comprises a base (1), a driving rubber roller (2), an expanding subshaft (3), an auxiliary front shaft (4), an auxiliary rear shaft (5), a front subshaft (6), a rear subshaft (7), a belt (8), a drawing stirring jaw (9) and a sensor (20), the driving rubber roller (2) and the expanding subshaft (3) ) are symmetrically arranged relative to a perpendicular line, the auxiliary front shaft (4) and the auxiliary rear shaft (5) are symmetrically arranged relative to the same perpendicular line, the front subshaft (6) and the rear subshaft (7) are symmetrically arranged relative to the same perpendicular line, the belt (8) is closely matched with the periphery of the driving rubber roller (2), the periphery of the auxiliary rear shaft (5), the periphery of the auxiliary front shaft (4) and the periphery of the expanding subshaft (3), the lower portion of the front subshaft (6) and the lower portion of the rear subshaft (7) are pressed on the belt (8), the drawing stirring jaw (9) is used for guiding the end portions of drawings, the driving rubber roller (2) is driven by a servo motor, and the sensor (20) is arranged in the drawing feed direction. The transverse folding mechanism is used for folding the large-width drawings, folds are clear and linear, and folding widths are consistent.

Description

technical field [0001] The invention relates to a folding device suitable for drawings used in machinery, engineering, construction and other industries, in particular to a cross-folding mechanism of a folding machine. Background technique [0002] A stacking machine is a machine that specializes in folding printed and copied large-format drawings into specifications for archiving. The folding machine of the prior art generally includes a horizontal folding mechanism and a vertical folding mechanism. The horizontal folding mechanism folds the large-format drawings horizontally into the width of the archive specification, such as a width of 210mm when folded into A4 specifications, and the vertical folding mechanism vertically folds the large-format drawings. It is folded into the length of the archive standard, such as the length of 297mm folded into the A4 standard. [0003] The Chinese utility model patent with the notification number CN201087052Y discloses a stacking mac...

Problems solved by technology

[0005] Combining the above text with the accompanying drawings of the patent document, it can be seen that: (1) Before the drawing is ready to be folded, the drawing only uses the inner side of the right end plate and the rear side of the worktable as a positioning reference, and then only Placed on the workbench without specific positioning means, the drawings are prone to displacement, which affects the subsequent folding process; (2) The drawings are pressed down by the front and rear pressing boards to realize the folding of the drawings again and again. However, the front and rear press boards are hinged structures, which makes it impossible for the press ends of the front and rear press boards to completely compact the folded edges, so that the pressed creases are not real; The reciprocating movement of the rod completes the folding of the drawing. Manual operation is not only cumbersome and costly, but also the trajectory and distance of the manual operation cannot be completely consistent, which leads to the situation that the folding width is different and affects the folding quality.
