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
