Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0035] When the printing press is working, it is necessary to continuously feed paper to the printing press to ensure that the printing press can work without interruption. For double-sided printing machines, it is also necessary to turn the paper over to facilitate printing on both sides. The invention provides a flipping device for a paper feeder of a double-sided printing device, such as figure 1 As shown, the paper feeder includes a feeding mechanism 1 for fee...

Abstract

The invention relates to the field of paper feeders, in particular to a turnover device of a paper feeder of double-sided printing equipment. The paper feeder comprises a feeding mechanism for feeding printing paper and a conveying mechanism for conveying the printing paper, and transverse reciprocating motion mechanisms are arranged on the two sides of one end of the conveying mechanism. A longitudinal reciprocating motion mechanism is arranged between the transverse reciprocating motion mechanisms, and a printing mechanism is installed on the longitudinal reciprocating motion mechanism. Turnover mechanisms are arranged on the two sides of the other end of the conveying mechanism and achieve up-down and left-right position adjustment through a driving mechanism, a dryer is arranged between the turnover mechanisms and the longitudinal reciprocating motion mechanism, and the printing paper is turned over after passing through the dryer after being printed. The overturning mechanisms can overturn the printing paper by 180 degrees through cooperation of a vacuum suction nozzle and the driving mechanism, manual operation is not needed, the printing paper is dried during overturning, the overturned printing paper enters a second conveying belt, multi-layer stacking can be achieved, and follow-up double-face printing is facilitated.

Description

technical field [0001] The invention relates to the field of paper feeders, in particular to an overturning device for a paper feeder of double-sided printing equipment. Background technique [0002] When the printing press is working, it is necessary to continuously feed paper to the printing press to ensure that the printing press can work without interruption. For double-sided printing machines, it is also necessary to turn the paper over to facilitate printing on both sides. [0003] In the prior art, manual operations are mostly used for paper feeding operations, and the paper is sent to the bottom of the printing machine for printing, and the work efficiency is low. When performing double-sided printing, it is necessary to wait for the printing surface to dry before manually turning it over to print on the second side. The work efficiency is low and the waiting time is long, which affects printing efficiency. Contents of the invention [0004] In order to solve the...
