Device for displacing printing pressing force and eliminating tolerance clearance of curved-surface printing machine

Abstract

The invention relates to a printing machine, in particular to a device for displacing printing pressing force and eliminating a tolerance clearance of a curved-surface printing machine. The device for displacing the printing pressing force and eliminating the tolerance clearance of the curved-surface printing machine comprises a printing device which is arranged on a base and is provided with a multi-work-position stepping indexing turntable and a mould handle, and a printing main machine which is arranged on a main machine supporting frame and provided with a transferring printing large drum, and is characterized in that a two-dimensional orthogonal sliding seat is arranged on the base, the main machine supporting frame is arranged on the two-dimensional orthogonal sliding seat through a main machine seat plate, the base is further provided with a longitudinal moving device used for eliminating the clearance, and a programmable logic controller (PLC) which is used for controlling the longitudinal moving device used for eliminating the clearance and is provided with a touch screen, and the longitudinal moving device used for eliminating the clearance is arranged between the base and the main machine seat plate, controls the main machine seat plate to move in the direction perpendicular to the axis of the mould handle, and eliminates the tolerance clearance. The device for displacing the printing pressing force and eliminating the tolerance clearance of the curved-surface printing machine is convenient to operate, is small in vibration, and meets the accuracy requirement for high-speed operation at the speed of 450-650 cups per minute in the cup printing process, and the speed of cup printing is improved by one time compared with existing equipment.

Description

[0001] The present invention is a divisional application, the original application number is: 201110006397.1, the application date is January 05, 2011, and the invention name is the divisional application of the displacement printing pressing force and gap tolerance elimination device of a curved surface printing machine. technical field [0002] 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 [0003] 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 mat...

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

[0005] 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.

[0006] 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
