Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to a carbon ribbon high-speed coating machine. Background Art

[0002] Carbon ribbon is a very important material for printing. Generally speaking, the quality of carbon ribbon not only determines the life of the print head but also affects the printing effect. A good carbon ribbon can protect the print head and the effect produced can be accurately attached to the paper without spreading or falling off. The production of carbon ribbon requires the use of a carbon ribbon coating machine.

[0003] The existing carbon ribbon coating machine is basically composed of components such as a positioning roller, a coating roller, a coating box and a conveying roller. When the existing carbon ribbon coating machine is in use, the carbon ribbon is first passed through the positioning roller, the coating roller and the conveying roller. The positioning roller limits the carbon ribbon to make the carbon ribbon passing through the coating roller straight. The coating roller coats the carbon ribbon with the coating provided by the coating box, and then the coated carbon ribbon is conveyed through the conveying roller.

After one coating is completed, the carbon ribbon needs to be manually removed and replaced, and then the white film is installed on the coating machine for another coating process. This operation reduces the coating efficiency of the white film and increases manpower consumption. Utility Model Content
