[0002] As people's requirements for quality of life increase, the technology of various label products is also gradually improving, and more and more label products are used in various products in life. Flexographic printing is a kind of relief printing process, which uses a flexible printing plate and transfers ink through an anilox roller. The image part of the flexible printing plate is raised. During printing, the anilox roller evenly applies a certain thickness of ink layer on the image part of the printing plate, and then under the pressure of the impression roller, the ink layer of the image part is transferred to the surface of the substrate to form a clear image.

[0003] The transmission device of the traditional flexographic printing machine uses the bottom roller as the power roller. The gear on the bottom roller transmits the power to the anilox roller through the intermediate gear, and another gear on the bottom roller transmits the power to the plate roller. Such a transmission bottom roller needs to be equipped with two gears and two intermediate gears. The assembly and debugging process is complicated and ink bars are prone to occur. The traditional transmission method has low precision and ink bars are prone to occur during the printing process. In addition, the cost of parts is also increased.
