Abstract

The invention provides an axial adjusting and controlling system of a printing plate roller of a corrugated board printer. The printing plate roller is arranged between a power side mechanical wall board and an operating side mechanism wall board. The roll shaft of the printing plate extends out of the operating side mechanism wall board to be in transmission connection with a mechanical reducing mechanism. The mechanical reducing mechanism is in transmission connection with a motor which is connected with a reversible contactor. The system is characterized in that double synchronous pulleys are arranged at the roll shaft of the printing plate. The double synchronous pulleys are respectively connected with a rotary coder and a mechanical transmission limiting system. Based on axial adjustment and electric control of current printing plate roller of the corrugated board printer unit, a mechanical axial limiting system is further arranged, so that when the axial device of the device changes out of the allowed range, the system can stop the machine under the effect of the mechanical axial limiting system to ensure the safety of the device.

Description

technical field [0001] The invention belongs to the technical field of corrugated cardboard printing machinery, and particularly relates to an axial adjustment control system of a printing plate roller of a printing press. Background technique [0002] With the development of corrugated cardboard printing press technology, servo drive high-precision corrugated cardboard printing presses are widely used, and multi-color overprinting technology is more mature. The corrugated board watermarking machine in the prior art uses a flexographic printing plate, and the printing plate is centered and hung on the printing plate roller. First of all, the vertical and horizontal registration should be carried out in the state of passing the cardboard. The vertical registration is completed by adjusting the phase of the servo motor, and the horizontal registration is completed by the axial adjustment control system of the printing plate roller; therefore, the axial movement of the printing...
