Displacement printing pressing force and tolerance clearance removing device of curved surface printing machine

Abstract

The invention relates to a printing machine, in particular to a displacement printing pressing force and tolerance clearance device removing of a curved surface printing machine. The device comprises a printed device, a printing host, a longitudinal moving device for removing clearance and a programmable controller, wherein the printed device is arranged on a substrate and is provided with a multistation stepping indexing turntable and a die handle, and the printing host is arranged on a host bracket and is provided with a transfer print bass drum wheel. The device is characterized in that the substrate is provided with a two-dimensional orthogonal side; the host bracket is arranged on the two-dimensional orthogonal side by a host seat plate; the programmable controller controls the longitudinal moving device for removing clearance and is provided with a touch screen; and the longitudinal moving device for removing clearance is arranged between the substrate and the host seat plate to control the host seat plate to move along the direction vertical to the axis of the die handle and remove the tolerance clearance. The displacement printing pressing force and tolerance clearance removing device of a curved surface printing machine, which is disclosed by the invention, is convenient to operate and has small vibration, the precision requirement that a print cup rotates at high speed of 450-650 per minute can be satisfied, and the operation speed is two times of that of the print cup of the existing equipment.

Description

technical field [0001] The invention relates to a printing machine, in particular to a displacement printing pressing force and gap tolerance elimination device for a curved surface printing machine. Background technique [0002] Curved surface printing machine, also known as curved surface offset printing machine, cup and bowl printing machine, circular printing machine, cylindrical curved surface printing machine, bottle cap curved surface printing machine, the traditional curved surface printing machine includes a large transfer drum wheel 1 with a transfer blanket, and The main printing machine composed of the ink units of each color version roller matched with the large transfer drum 1 is composed of a multi-station step indexing turntable 2, a mold handle 3 installed on it (the printing workpiece is installed on the mold handle 3) and a driving tray The printing device formed by the stepping and rotating driving device; the printing host and the printing device are all...

AI Technical Summary

Problems solved by technology

Since the pressure adjustment is realized by manually inching the motor, it has to be operated by experience, which cannot achieve the purpose of precise and automatic control. At the same time, it is not convenient to adjust the vertical and horizontal and angle adjustments. Machining accuracy errors in shafts, screws, nut tubes, gears, racks, rails and sliders cause large vibrations during high-speed production and cannot meet the requirements of high-precision and high-speed printing

[0004] Another patent application of the present inventor, 200820008243.X, is an automatic device for cup printing machines. There are also natural tolerances between the transmission parts, which makes it impossible to meet the high-speed operation accuracy requirements of 450-650 pieces per minute.

[0005] With regard to the defects of the above-mentioned existing curved surface printing machine due to processing accuracy errors, the vibration is very large during the high-speed production process, and cannot meet the requirements of high-precision, high-speed printing. The inventor finally created the curved surface printing machine of the present invention after repeated research and development. The advanced displacement printing pressing force and gap elimination tolerance device can not only eliminate the gap and reduce vibration, but also can collect the shooting switch, proximity switch and corona device on one side according to the upper mold on the turntable during the automatic production process. Empty cup, double cup, broken cup signal, automatically control the longitudinal displacement device to automatically and quickly clutch and move
