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 200820008243 of the inventor. X An automation device for cup printing machines also has natural tolerances between the transmission components, 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

Embodiment 1

[0035] see figure 1 , image 3 , Figure 7 As shown, the displacement printing pressing force and gap tolerance elimination device of the curved surface printing machine of the preferred embodiment of the present invention includes a printing device with an eight-station stepping indexing turntable 2 and a mold handle 3 arranged on a base 4 And be located at the printing main frame that has transfer printing big drum wheel 1 on the main frame support 5. The base 4 is provided with a two-dimensional orthogonal sliding seat, and the main frame 5 is arranged on the two-dimensional orthogonal sliding seat through the main base plate 6; in order to solve the tolerance gap due to the longitudinal moving device in high-speed printing And the vibration that produces, also be provided with the vertically moving device 110 that eliminates gap, the embedded controller 8 with touch screen 7 that controls above-mentioned vertically moving device 110 that eliminates gap, the vertically mo...

Embodiment 2

[0042] Such as Figure 4 , Figure 5 , Figure 7 Shown is a schematic diagram of Embodiment 2 of the high-speed curved surface printing machine of the present invention. The difference between this embodiment and Embodiment 1 is: the large-scale clutch device is connected to the connecting plate 116 through the clutch cylinder 121; the large-scale clutch device also includes a large-scale clutch cylinder 171, a large-scale clutch solenoid valve 172, the cylinder block of the large-scale clutch cylinder 171 is fixed to the base 4 through the hinge support 173, and the function of the hinge support 173 is to make the large-scale clutch cylinder properly rotate around the hinge support 173. To adjust the height error between the clutch cylinder 121. The cylinder shaft of the large-scale clutch cylinder 171 is connected to the cylinder body of the clutch cylinder 121, and the cylinder shaft of the clutch cylinder 121 is connected to the connecting plate 116 through the plug con...

Embodiment 3

[0048] Image 6 , Figure 7 It is another embodiment of the longitudinal movement device for eliminating the tolerance gap in the displacement printing pressing force and gap tolerance device of the curved surface printing machine of the present invention. In this example:

[0049] The longitudinal pressing force adjustment device 130 includes a longitudinal movement motor 131, two longitudinal screw nut tube transmission devices 132 symmetrically arranged on both sides of the longitudinal movement motor 131, and two longitudinal screw nut tube transmission devices 132 arranged outside or below the two longitudinal screw nut tube transmission devices respectively. The longitudinal gap elimination cylinder 133, the gap elimination electromagnetic valve 134 and the fixed plate 135 connecting the two longitudinal gap elimination cylinders 133, the longitudinal movement motor 131 and the two longitudinal gap elimination cylinders 133 are fixed on the top of the fixed plate 135 O...
