[0002] UV ink refers to the use of ultraviolet light of different wavelengths and energies to polymerize the monomers in the ink binder into polymers under ultraviolet light. During the production process of UV ink, a mixing device is required to stir the ink. The stirring structure of the existing UV ink mixing device can generally only rotate and stir in a specific area, which has poor flexibility, resulting in poor mixing efficiency and effect. In addition, the ink often adheres to the inner wall of the mixing barrel during the stirring process, affecting the stirring effect. In addition, some UV ink will remain when it is discharged, which is difficult to completely clean, resulting in certain waste.

[0003] Therefore, it is necessary to propose a UV ink mixing device to solve the above problems. Utility Model Content
