The present invention is applicable to the field of printing technology, and provides an anilox heat printing roller for liquid crystal light guide plate, which includes quartz rods, high temperature resistant bearings, thick-walled quartz tubes, dots, and semiconductor heating film layers; the high temperature resistant bearings are installed on the The two ends of the quartz rod, the thick-walled quartz tube is installed on the quartz rod, the inner wall of the thick-walled quartz tube is coated with the semiconductor heating film layer, and the surface of the thick-walled quartz tube is provided with bumps. The dots of the liquid crystal backlight light guide plate of the present invention no longer need ink printing, the printing size can be infinitely large or small, the scrap rate is reduced, defective products can be repaired, and dirt can be cleaned, which completely solves the current high scrap rate of the current light guide plate printing technology, ink Printing has disadvantages such as polluting the environment, and the processing cost is also greatly reduced. Since a line on the outer diameter of the roller is always in contact with the surface of the light guide plate, the curvature error can be controlled within 0.2%, and there is no need for baking or ultraviolet light at the same time.
Description
technical field [0001] The invention belongs to the technical field of printing, and in particular relates to an anilox thermal printing roller for a liquid crystal light guide plate. Background technique [0002] Now there are mainly three kinds of light guide plate printing technology: a. Injection molding technology. This technology is mainly used in small and medium sizes, below 23.6 inches. b. Screen printing technology. This technology is mainly used in 15-inch and above. It needs printing ink, and the defect rate is high. After forming, it cannot be repaired, and the scrap rate is high. The highest scrap rate of LED light guide plate printing is about 40%. c. Laser engraving technology. The technology is low in cost, good in dots, but too slow to be suitable for production. Contents of the invention [0003] The purpose of the embodiment of the present invention is to provide an anilox thermal printing roller for liquid crystal light guide plate, aiming to solve...
