Problems solved by technology

[0002] For traditional gravure printing machines, the current control method of the hot air system of the whole machine is to manually adjust the opening of the air intake, exhaust, and return air valves according to the experience of the installation personnel, and there are different printing processes in the process of use. For speed or layout area, it is necessary to manually adjust the opening of each damper to meet the requirements of printing drying performance and oven negative pressure. Meet the requirements of intelligent operation

Embodiment

[0052] This embodiment provides a method for controlling the color group air door of a printing machine, the printing machine is a five-color (five color groups in total) printing machine, and the rated maximum printing speed of the printing machine is V max =300m / min, specifically follow the steps below:

[0053] Step 1: Install electric damper actuators on the air intake, exhaust and return air dampers of the color group oven;

[0054] Step 2: Preset the parameters of the effective layout area range of the color group plate roller, and preset the opening values ​​corresponding to the air inlet, exhaust, and return air damper actuators corresponding to the effective layout area of ​​different plate rollers;

[0055] Step 3: Read the effective printing layout area and total layout area of ​​the color group printing roller on the drawing of the printing roller;

[0056] Step 4: Select the damper gear corresponding to the effective layout area of ​​the color group plate roller,...

Abstract

The invention discloses a control method for color cell air doors of a printing machine. The control method is specifically implemented according to the following steps that firstly, electric air door actuators are installed on an air inlet door, an air exhaust door and an air return door of a color cell drying oven; 2, presetting parameters of an effective layout area range of the color group plate roller, and presetting opening values corresponding to air inlet, air exhaust and air return damper actuators corresponding to different effective layout areas of the plate roller; 3, reading the effective printing layout area and the total layout area of the color group plate roller on the plate roller drawing; and 4, selecting an air door gear corresponding to the effective layout area of the color group plate roller, automatically executing a preset air door opening degree by an air door executor according to the selected gear, and automatically calculating the current maximum running speed according to the total effective printing layout area, so as to complete the control on the color group of the printing machine. The opening degree of the air door can be automatically adjusted according to the effective printing layout area, and the intelligent requirement for air door control is met.
