Abstract

The invention provides a rotary adjusting device of a printing machine duct. The rotary adjusting device aims at solving the problem that when a duct roll is adjusted to the operation angle, a large amount of time needs to be consumed on repair, and the needed effect cannot be achieved. The rotary adjusting device of the printing machine duct comprises a mounting base, a guide block, a threaded rod, a connecting rod and a clamping device used for enabling the guide block and the threaded rod to be clamped. The threaded rod is arranged on the mounting base. A threaded hole is formed in the guide block, the threaded rod is inserted into the threaded hole, and one end of the threaded rod is connected with a driving device. A duct roll angle change fulcrum connected with the guide block is arranged at one end of the connecting rod, and a one-way bearing for being connected with a duct roll is arranged at the other end of the connecting rod. According to the rotary adjusting device, the turnover angle of the duct can be precisely and conveniently controlled, and therefore the ink adding amount of the duct is controlled. The clamping device enables the guide block and the threaded rod to be clamped, and therefore the problem that due to long-term running-in of a guide block and a threaded rod, clearance looseness occurs can be solved.

Description

technical field [0001] The invention relates to a device for adjusting the rotation amount of an ink fountain roller of a flat printing machine, in particular to a device for adjusting the rotation of an ink fountain roller of a printing machine. Background technique [0002] In the prior art, the flat printing machine is mainly composed of ink, printing plate, rubber, and embossing. In the whole process, the ink is transferred through the ink fountain roller. The pattern of the printed matter is mainly based on the amount of ink and the angle of the ink fountain roller transfer. Control the ink depth. The structure of the ink fountain roller in the prior art is mainly composed of a one-way bearing, a motor servo controller, and a running angle transfer control screw; when the pc system inputs the running angle signal of the ink fountain roller to the servo drive, the motor rotates the screw to the set angle , through the reciprocating movement of the one-way assembly to fo...
