Abstract

The invention discloses an automatic on-off pressure device of an offset press. An impression cylinder, a rubber cylinder, a plate cylinder and an on-off pressure shaft are mounted between and on left and right wallboards, a driver is mounted at one end of the on-off pressure shaft and is fixed on the left wallboard and the right wallboard through a support shaft, shaft heads at two ends of the rubber cylinder are symmetrically provided with a left eccentric sleeve and a right eccentric sleeve, a left gear block and a right gear block are mounted on the left eccentric sleeve and the right eccentric sleeve, and a left gear and a right gear which are meshed and rotate are mounted on the left gear block and the right gear block. The driver directly drives the on-off pressure shaft to move, adjustment of printing pressure of the rubber cylinder and the impression cylinder is realized, automation level is high, cost is low, mechanical performance is reliable and stable, printing assisting time is short and labor intensity is thereby reduced.

Description

[0001] Technical field: [0002] The invention relates to an automatic clutch pressure device of an offset printing machine, which is especially suitable for adjusting the printing pressure of a rubber cylinder and an impression cylinder. Background technique: [0003] The clutch pressure device on the existing offset printing machine is to adjust the pressure of the rubber cylinder, the printing plate cylinder and the impression cylinder. The sleeve (outer eccentric sleeve) manually adjusts the pressure between the rubber cylinder and the impression cylinder through sector teeth, gears, supporting shafts, adjustment rods, handles and other parts, and the inner eccentric sleeve (inner eccentric sleeve) through Connecting rods, clutch pressing shafts, swing rods, fulcrums, swinging frames, rollers, cams and other components are used to control the pressing and releasing actions of the rubber cylinder, the printing plate cylinder and the impression cylinder. Its disadvant...
