Paper output mechanism that supports double-sided printing

Abstract

The invention provides a paper outlet mechanism supporting double-sided printing. The paper outlet mechanism comprises a rack and a conveying channel, a control center is arranged in a printing module, and the paper outlet mechanism further comprises a transmission chain driven by a motor, a first rolling wheel set and a first sensor. The first rolling wheel set is arranged on one side of a paper outlet of the printing module and in transmission with the transmission chain, and the first sensor is arranged between the first rolling wheel set and the paper outlet of the printing module and used for detecting whether paper passes through the transmission channel or not. The first rolling wheel set comprises a fixed rolling wheel and a movable rolling wheel which are arranged on the two sides of the conveying channel in an opposite rolling mode, and a rolling wheel lifting device, and the rolling wheel lifting device is instructed by the control center and can lift the movable rolling wheel to enable the movable rolling wheel and the fixed rolling wheel to be out of opposite rolling arrangement. The paper outlet mechanism can assist in paper conveying of the printing module, and cooperates to carry out paper conveying according to a single-sided printing instruction or a double-sided printing construction to support and achieve double-sided printing, and the paper outlet mechanism is simple in structure and modular.

Description

technical field [0001] The invention relates to a paper output mechanism of a printer, in particular to a paper output mechanism supporting double-sided printing. Background technique [0002] There is generally a long distance between the printing outlet of the printing module and the paper outlet of the panel, and it is necessary to set up a paper ejection mechanism to assist paper ejection. The paper ejection mechanism in the prior art generally cannot recognize the difference between the two printing situations, and does not support double-sided printing. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a paper output mechanism that can cooperate with the printing module to transfer corresponding paper according to single-sided printing or double-sided printing instructions, thereby supporting double-sided printing. [0004] The technical solution of the present invention to solve the above-mentioned techni...
