Automatic register adjusting device of printing machine

Abstract

The invention provides an automatic register adjusting device of a printing machine. The automatic register adjusting device comprises a screen frame fixing adjusting assembly located on a printing machine head and used for fixing a printing plate screen frame, the screen frame fixing adjusting assembly comprises an adjusting frame used for holding and fixing the screen frame, an electric motor isarranged in the adjusting frame, and positive and negative rotation of the electric motor is used for achieving transverse or / and longitudinal moving of the screen frame relative to the machine headposition. The electric motor is arranged on a traditional adjusting screw rod, a spindle of the electric motor is connected with a thread rod for register adjusting, positive and negative rotation ofthe electric motor is used for driving the thread rod to positively and negatively rotate, positive and negative rotation of the electric motor can achieve external manual control over positive and negative rotation, through an industrial computer, positive and negative rotation can be controlled, rapid register can be achieved, in addition, a traditional outer adjusting nut is still kept, manualadjusting is achieved, and three adjusting functions are integrated.

Description

technical field [0001] The invention relates to the technical field of printing machine equipment, in particular to a printing machine plate alignment device, in particular to an automatic plate alignment adjustment device for a printing machine. Background technique [0002] As we all know, the current printing machines are mainly oval printing machines, but at present, no matter whether it is oval printing machines or other forms of printing machines, manual plate alignment is basically used. When printing the same batch of the same pattern, The use of manual labor is only a one-time labor. Of course, it also requires a lot of time and energy to perform plate alignment. However, when encountering multiple batches and multiple pattern printing, it is necessary to perform plate alignment before each new pattern is printed, which is time-consuming. strenuous. [0003] Chinese Patent Publication Patent No. 201820812618.1 is an invention patent of a pneumatic intelligent plate...

AI Technical Summary

Problems solved by technology

The common problem of manual plate alignment is that the adjustment efficiency is low. If there are 10 heads on an oval printing machine, then the corresponding printing plates on the 10 heads need to be adjusted in order to ensure that the 10 heads are printed properly. High printing accuracy, time-consuming and labor-intensive, low efficiency
