Rotary press roller clutch press with novel eccentric bushing device

Abstract

The invention relates to a rotary press roller clutch press with a novel eccentric bushing device. An eccentric bushing cover of a rubber roller A is arranged on the outer wall of an eccentric bushing of the rubber roller A; an A type wallboard hole bushing is arranged on the inner wall of an A type wallboard hole; a support bearing of the rubber roller A is mounted in an eccentric bushing inner hole of the rubber roller A; a roller shaft head of the rubber roller A is mounted in a support bearing inner hole of the rubber roller A; the eccentric bushing cover of the rubber roller A fits the A type wallboard hole bushing; an eccentric bushing cover of a plate cylinder B is arranged on the outer wall of an eccentric bushing of the plate cylinder B; a B type wallboard hole bushing is arranged on the inner wall of a B type wallboard hole; a support bearing of the plate cylinder B is mounted in an eccentric bushing inner hole of the plate cylinder B; a roller shaft head of the plate cylinder B is mounted in a support bearing inner hole of the plate cylinder B; and the eccentric bushing cover of the plate cylinder B fits the B type wallboard hole bushing. The rotary press roller clutch press with novel eccentric bushing device simplifies the repairing process of the eccentric bushing of the rubber roller A and the eccentric bushing of the plate cylinder B, shortens the repairing stop time, and guarantees the printing quality.

Description

technical field [0001] The invention relates to the technical field of printing machine equipment, in particular to a cylinder clutch pressure of a rotary printing machine with a novel eccentric sleeve device. Background technique [0002] The clutch pressure mechanism and printing pressure adjustment device in the rotary printing machine generally adopt the eccentric mechanism, and the eccentric sleeve is an important part of the eccentric mechanism. The main function of the eccentric sleeve is to support the printing cylinder, realize the clutch pressure, and adjust the printing pressure. In order to ensure the quality of the printed product, the pressure adjustment must be sensitive and accurate. The size and shape of the eccentric sleeve require high precision. The basic principle of the eccentric sleeve mechanism is to place the shaft head of the printing cylinder in the inner hole of the eccentric sleeve. The circumferential position in the hole can change the center ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to aim at the existing eccentric sleeve device applied to the cylinder clutch pressure of the rotary printing machine, when the wallboard is in direct contact with the eccentric sleeve, when the wallboard hole and the eccentric sleeve are worn out, and the wallboard hole wears out and an elliptical hole needs to be repaired , can only adopt the repair plan of enlarging the bore of the wallboard hole, and then matching it with an eccentric sleeve that is compatible with it, resulting in technical problems such as large repair costs, high cost, and long cycle. A new type of eccentric sleeve device is provided. Rotary printing machine cylinder clutch pressure, to ensure that the maintenance method after the wear of the eccentric sleeve is simple, the equipment downtime is short, the maintenance efficiency is improved, and the maintenance cost is reduced
