Driving device for printing roll of high-speed electronic shaft transmission printing machine

Abstract

The invention discloses a driving device for a printing roll of a high-speed electronic shaft transmission printing machine, which can improve the overprinting precision and make the overprinting precision stable. The driving device for the printing roll of the high-speed electronic shaft transmission printing machine comprises a servo motor (1), a shaft coupler (2), a box body (3) and a printing roll driving shaft (4), wherein the servo motor (1) is connected with the box body (3); the output shaft of the servo motor (1), the shaft coupler (2) and the printing roll driving shaft (4) are connected sequentially; the part between the two ends of the printing roll driving shaft (4) is positioned in a shaft sleeve (5); the printing roll driving shaft (4) is rotationally connected with the shaft sleeve (5); one end of the shaft sleeve (5) is connected with the box body (3); and the shaft sleeve (5) is in sliding fit with a machine frame (6) of the high-speed electronic shaft transmission printing machine.

Description

technical field [0001] The invention relates to the technical field of high-speed electronic shaft-driven printing machines, in particular to a printing plate roller driving device for high-speed electronic shaft-driven printing machines. Background technique [0002] At present, there is a high-speed (at least 200 meters per minute) electronic shaft drive printing machine printing plate roller driving device, which includes a servo motor, a coupling, a box, a transmission shaft and a printing plate roller drive shaft, the output shaft of the servo motor, The shaft device and the transmission shaft are connected in sequence. The transmission shaft is provided with a first gear, and the driving shaft of the printing plate roller is provided with a second gear connected with it through a spline. The first gear meshes with the second gear. The servo motor, transmission The shafts are all connected to the box, so that the servo motor and the drive shaft can be supported by the b...

AI Technical Summary

Problems solved by technology

[0003] It can be seen from the above that the power transmission law of the printing plate roller driving device of the high-speed electronic shaft transmission printing machine is as follows: the servo motor drives the coupling, the coupling drives the transmission shaft, the transmission shaft drives the first gear, and the first gear drives the second gear. Gear, the second gear drives the printing plate roller driving shaft, so that the printing plate roller driving shaft rotates, and the printing plate roller driving shaft can be used to drive the printing plate roller to rotate. It will gradually increase, and the accuracy will gradually decrease, which will affect the overprint accuracy during the printing process, and make the overprint accuracy not stable enough
