Dual-servo motor control device for flat plate type digital ink-jetting printing machine

Abstract

The invention provides a dual-servo motor control device for a flat plate type digital ink-jetting printing machine. Two high-precision servo motors 1 and 2 are adopted, wherein the servo motor 1 is used for controlling motions of a nozzle group in a width direction of a printed textile, and the servo motor 2 is used for controlling motions of a machine head subassembly in a length direction of the printed textile. Furthermore, the servo motor 2 is connected with the servo motor 1 by a signal converting device, so that the synchronous intermittent movement which is complementary in time of the servo motor 1 and the servo motor 2 is accurately traced. Therefore, the heights of the motions of the machine head subassembly are coordinated and consistent, and the high-precision requirement in printing can be effectively ensured. The device can be directly applied to the ordinary flat plate type digital ink-jetting printing machine and has the advantages of convenience for entire installation and high cost performance.

Description

technical field [0001] The present invention relates to the new technology field of digital ink-jet printing, and specifically relates to a motion control part of the head assembly of a flat-bed digital ink-jet printing machine, which realizes the coordinated movement of the head assembly through a pair of servo motor devices. device. Background technique [0002] Digital inkjet printing technology is a high-tech product that integrates machinery, computer, electronic information technology and gradually formed with the continuous development of computer technology. It first appeared in the mid-1990s. The emergence and continuous improvement of this technology , has brought a new concept to the textile printing and dyeing industry, and its advanced production principles and methods have brought an unprecedented development opportunity to textile printing and dyeing. It is known as the textile industry revolution technology in the 21st century, and it will gradually replace t...

AI Technical Summary

Problems solved by technology

In order to ensure printing accuracy, the movement of the machine head along the length of the fabric and the movement of the nozzle group along the width of the fabric must be highly coordinated. Only when the nozzle group prints a lead in the width direction of the fabric, the servo motor It will control the head assembly to move a printing width in the direction of the fabric length, otherwise it will seriously affect the printing effect
