Description

Technical Field

[0001] The utility model relates to the technical field of printing and winding, in particular to a winding device for a rotary printing machine. Background Art

[0002] A printing press is a machine for printing text and images. Modern printing presses are 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, which is then mounted on a printing press. Then, ink is applied to the places on the printing plate where the text and image are, either manually or by a printing press. Then, the ink is directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass, and ceramics), thereby replicating a printed product 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.

[0003] However, the prior art still has the following problems:

[0004] First, the winding device of the rotary printing machine in the prior art is not convenient for adjusting the tightness of the printed matter entering the winding device. If the printed matter is too loose when winding, it will cause uneven winding and even wrinkles. If it is too tight when winding, it may affect the quality of the printed matter.

[0005] Secondly, the winding device of the rotary printing machine in the prior art has a winding structure that is not easy to disassemble. Since the rolled printed matter sometimes needs to be moved after winding, if the rotating shaft is not easy to disassemble, the printed matter can only be released by unwinding it again, which consumes more electricity and is more troublesome.

[0006] In view of the above problems, the inventor proposes a winding device for a rotary printing press to solve the above problems. Utility Model Content
