Abstract

The invention provides label printing equipment. The label printing equipment comprises a rack. An ink addition device is arranged on the rack. The ink addition device comprises an ink addition box. A silk screen comprises a square fixing plate and a screen plate located at the bottom of the fixing plate. Ink input holes are formed in the fixing plate. Anti-flowing grooves are formed in the fixing plate. A number of anti-flowing holes communicating with the anti-flowing grooves are formed in the inner wall of the fixing plate. An ink addition cavity and an ink return cavity are formed in the ink addition box. Ink addition hoses extending into the ink input holes are connected to the ink addition cavity. An ink return groove is formed in the ink addition box. An ink return pipe is arranged in the ink return groove. One end of the ink return pipe communicates with the ink return cavity, and the other end of the ink return pipe communicates with the anti-flowing grooves. According to the label printing equipment, the ink addition box and the ink return pipe are arranged; ink flows out slowly through the ink addition hoses and is added; the output speed of ink is slower, and the ink is convenient to control and not easy to overflow; and moreover, when ink reaches a certain amount, ink backflows to the ink return cavity for storage from the ink return pipe, and thus waste caused by overflowing of ink is prevented.
