Problems solved by technology

In this way, the paper feeding cycle is fixed, even if the small-sized cardboard is conveyed, the cycle is the same, the smaller the cardboard, the larger the gap between the papers, the lower the efficiency, the larger the gap, and the ink droplets on the rear end Floating ink phenomenon occurs, and the printing effect becomes poor

Embodiment Construction

[0042] The present invention provides a method for controlling the paper feeding mechanism of a digital printing machine. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] see Figure 1-12 , a method for controlling a paper feeding mechanism of a digital printing machine, comprising the following steps:

[0044] A. Connect the human-machine interface (HMI), the main controller and the motion controller to the field communication bus. The main controller acts as the communication master station to control the communication of the bus and the operation of the motion controller. The motion controller controls the bus and the lift plate through t...

Abstract

The invention provides a control method of a paper feeding mechanism of a digital printing machine. According to the control method, different optimized cam curves are used according to different paperboards, and a variable paper feeding period is adopted; high precision and high dynamic response of a servo control system are utilized to achieve an advanced plate lifting control mode, so that thepaper board gap is reduced and the production efficiency is improved on the premise that the paperboards are not damaged and the printing precision is guaranteed.

Description

technical field [0001] The invention relates to the technical field of carton printing machinery, in particular to a control method for a paper feeding mechanism of a digital printing machine. Background technique [0002] The paper feeding of traditional carton inkjet printing machines is divided into non-precise paper feeding mode (A mode) and precise paper feeding mode (B mode). Method A generally uses friction to drive the bottom cardboard through the transmission belt, and the cardboard is separated to prevent the next cardboard from being driven. In this way, the cardboard is sent to the printing part one by one. This method is simple in mechanism and low in cost. Low, but it is easy to cause damage to the edge of the cardboard, and the paper feeding cycle cannot be guaranteed. [0003] Mode B is to ensure that the cardboard is fed into the machine through the cooperation of the precise movement of the feed wheel and grid plate controlled by the servo drive and the ap...
