Problems solved by technology

In this transmission process, due to the unavoidable working gap between the transmission shaft and the gearbox, between the internal gear on the output shaft of the gearbox and the printing plate shaft head gear, there is a transmission error in the work of each plate roller during the transmission process. , and the longer the transmission distance, the greater the error, and it is difficult for the rollers to be sy

Abstract

A forme roller gap-free transmission connection device is installed on a machine frame of a printing machine and at the position corresponding to a forme roller shaft head and consists of a support plate, a sliding rail, a bearing slide block, a fixing box, a servo motor, a coupler, a connecting shaft and an air cylinder. The support plate is installed on the lateral side of the machine frame of the printing machine and is perpendicular to the machine frame, the sliding rail is installed on the support plate, the fixing box is installed on the sliding rail, and the bottom of the fixing box is connected with the sliding rail through the bearing slide block. The servo motor is installed at one end of the coupler, a bearing penetrates through the middle of the connecting shaft, and a fixing sleeve of the forme roller shaft head is designed on an end head of the connecting shaft. A connecting notch is processed on the forme roller shaft head of the printing machine and is sleeved in the fixing sleeve. The air cylinder is installed at one end of the support plate, and an air cylinder shaft of the air cylinder is installed on the lateral side of the lower end of the fixing box. After adopting the forme roller gap-free transmission connection device, the transmission accuracy of a forme roller of the printing machine is improved, and the overprinting quality of products is improved greatly.

Description

technical field [0001] The invention belongs to the technical field of printing equipment, and relates to a gapless transmission connection device for printing plate rollers, which is especially suitable for multi-color group gravure printing machines. Background technique [0002] Multiple sets of printing plate rollers are installed on a multi-color printing machine. When performing color overprinting, the color group patterns on each printing plate roller must be overprinted accurately to print a clear pattern. The relative position and rotation coordination of the color blocks on each printing plate roller have a great influence on the overprinting accuracy. The relative position of the color blocks on each printing plate roller is affected by factors such as the geometric size of the printing plate processing, the accuracy of installation, and the working environment. Influence; the transmission fit accuracy is affected by the fit clearance of the transmission connector...
