Abstract

The invention discloses a stop mechanism for a transfer gripper in an offset press. The stop mechanism comprises a transfer roller, a transfer arm, a gripper opening and closing mechanism, and a protection mechanism. The gripper opening and closing mechanism comprises a driving gear, a gripper opening and closing control cam, a pair of driving swing bars, and a swing bar cam, wherein the driving gear and the gripper opening and closing control cam are fixedly mounted on a drive side shaft end of the transfer roller, one end of each driving swing bar is fixedly mounted on a swing bar shaft and the swing bar cam is mounted on a camshaft. The protection mechanism comprises a stop cylinder mounted on the inner side of a transmission side wallboard, a V-shaped swing bar, a stop link and a stop swing bar. The V-shaped swing bar is rotatably mounted on the inner side of a drive side wallboard through a pile head. One end of the V-shaped swing bar is hinged to a piton rod of the stop cylinder, and the other end of the V-shaped swing bar is hinged to one end of the stop link. The other end of the stop link is hinged to one end of the stop swing bar. The other end of the stop swing bar is fixed to the camshaft. The stop mechanism is capable of avoiding waste paper in case of an anomaly of paper on a discharge board.

Description

technical field

[0001] The present invention relates to an offset printing machine, in particular to a stop mechanism of the paper delivery teeth of the offset printing machine, which is used for preventing abnormal paper from entering the printing when the paper feeding mechanism is abnormal. The purpose of the unit. Background technique

[0002] The paper transfer mechanism in the offset printing machine is divided into three categories according to the route of the paper transfer: direct paper transfer, indirect paper transfer and beyond the continuous paper.

[0003] Direct paper transfer is the way that the paper is directly picked up by the tooth row on the impression cylinder after the paper feeding board is positioned.

[0004] Indirect paper transfer means that after the paper is positioned on the paper feeding board, it is first picked up by the tooth row of the paper delivery mechanism, and then delivered to the tooth row on the impression cylinder by the paper d...
