A kind of intermittent flat screen printing machine with back side cleaning

Abstract

The invention discloses an intermittent flat screen printing machine with edge cleaning of the back material. The structure includes a main body of the printing machine, a control panel, a working panel, a device for cleaning the back material, a moving frame, an ink return knife and an ink scraper. Beneficial effects: the present invention uses the electrostatic plate and the flat plate to fix the label under the action of the electrostatic plate when the printed label passes through the back material side cleaning device to prevent the occurrence of displacement. Position phenomenon, using the bottom scraping mechanism in the process of rotating movement, through the scraping bar to do rotating scraping on the back of the label edge under the action of rotating movement, so as to avoid a large number of spots on the back of the label after the printing is completed. The printing material thus affects the printing quality. The arc-shaped cylinder is placed above and close to the bottom scraping mechanism, and the printing material scraped by the bottom scraping mechanism is wiped when it is in contact with the rubbing cotton, and it is installed movable through the partition , which can make the cotton rubbing be utilized to the maximum degree during the rotary motion of the bottom scraping mechanism.

Description

technical field [0001] The invention relates to the field of label printing in the logistics industry, more precisely, it is an intermittent flat screen printing machine with side cleaning for back material. Background technique [0002] Labels are one of the more commonly used labels for labeling information on physical objects. Usually in the logistics industry, when they are used to briefly label the product name, weight, volume, usage and other information of the item, different label styles need to be used for posting. Because the surface of the label is smooth, when using the intermittent flat screen printing machine to print different styles of labels, due to the smooth nature of the label itself, the printed material is easier to slide on the surface, and when the printed material is finished Finally, when the squeegee is scraping off the excess printing material back and forth, the excess printing material will flow to both sides after being scraped off the label by...

[0002] Labels are one of the more commonly used labels for labeling information on physical objects. Usually in the logistics industry, when they are used to briefly label the product name, weight, volume, usage and other information of the item, different label styles need to be used for posting. Because the surface of the label is smooth, when using the intermittent flat screen printing machine to print different styles of labels, due to the smooth nature of the label itself, the printed material is easier to slide on the surface, and when the printed material is finished Finally, when the squeegee is scraping off the excess printing material back and forth, the excess printing material will flow to both sides after being scraped off the label by the squeegee to form accumulations. At this time, the label is printed When transporting by pulling backwards and forwards, the excess ink will move with the label during the forward pulling process, resulting in a thicker printing material on the edge of the label, which will form agglomerates after air drying
