Description

Technical Field

[0001] The utility model relates to the field of printing machines, in particular to a roll-removing device of a continuous label printing machine. Background Art

[0002] A printing press is a machine for printing text and images. A modern printing press is generally composed of mechanisms such as plate mounting, inking, embossing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate and mounted on a printing press. Then, ink is applied to the places with text and images on the printing plate by humans or a printing press, and then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass and ceramics), thereby replicating printed products identical to the printing plate. The invention and development of the printing press has played an important role in the spread of human civilization and culture. A label printing press is a type of printing press.

[0003] After the labels on the rolls in the existing label printing machines are printed, the label printing roller needs to be removed and replaced with a new roll, but the existing label printing roller cannot be quickly removed, so the replacement speed of the label roll is slow.
