Four-color fully-automatic printing machine

Abstract

The invention provides a four-color fully-automatic printing machine comprising a frame, a rotary table, printing screen plate devices, printing scraping plate devices, a cup loading device, a cup unloading device, a six-station precise protractor and automatic vacuum suction cup devices, wherein the rotary table, the printing screen plate devices, the printing scraping plate devices, the cup loading device and the cup unloading device are arranged on the frame; the six-station precise protractor controls the rotary table to protract, position and rotate; the number of the automatic vacuum suction cup devices is six, and the automatic vacuum suction cup devices can realize the 360 degree seamless rotation of a cup body and are evenly positioned on the rotary table by the six-station precise protractor; the numbers of the printing screen plate devices and the printing scraping plate devices are respectively four, the printing screen plate devices and the printing scraping plate devices are respectively and continuously arranged above the four automatic vacuum suction cup devices and are matched with printing patterns, and the cup loading device and the cup unloading device which are used for loading and unloading cups as well as the other two automatic vacuum suction cup devices are positioned. The four-color fully-automatic printing machine has high work efficiency and safe and stable working performance and can realize seamless four-color thermal printing of 360 degrees and save large labor force.

Description

Technical field: [0001] The invention relates to a printing machine, in particular to a four-color full-automatic printing machine capable of realizing 360° seamless thermal printing. technical background: [0002] At present, most of the packaging labels on glass bottles are printed on wrapping paper or packaging molds, and then the bottle body is decaled by hand. It does not require high technology, the product appearance quality is low, and there are many processing procedures. In the existing technology, the printing of glass cone vessels usually adopts the traditional printing method: the first color is printed on a manual machine by 3 people, and the second and third colors are very slow due to the need for manual registration and positioning. Four groups of 12 people complete the work, and the fourth color positioning is even more difficult, with poorer precision and lower pass rate. [0003] In the 1970s, three sets of color printing machines were produced, which we...

Problems solved by technology

In the existing technology, the printing of glass cone vessels usually adopts the traditional printing method: the first color is printed on a manual machine by 3 people, and the second and third colors are very slow due to the need for manual registration and positioning. Four groups of 12 people will complete the work, the fourth color positioning is more difficult, the accuracy is worse, and the pass rate is lower

[0003] In the 1970s, three sets of color printing machines were produced, which were semi-automatic manual upper and lower cups. The circumference of the printed glass cone could not exceed 350 degrees, and the error of each color registration was relatively large. Slow, labor-intensive, pass rate depends on human technology and responsibility, and is extremely unstable. Although the latter uses semi-automatic instead of manual operation, 6 people are needed to complete 35 pieces / minute, but due to poor positioning accuracy, only the circumference can be printed 350°, so the products are not up to grade, and can only be sold in rural areas (such as Double Happiness, Red Lantern, etc.), and the printed pattern products cannot go abroad at all.
