Description

Technical Field

[0001] The utility model relates to the field of inkjet printers, and more specifically to an impression roller for inkjet printers. 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, 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 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] For example, a metal lithographic offset printing impression roller disclosed in announcement No. CN207373898U comprises a machine body and a left roller, a right roller is arranged on the right side of the left roller, a sliding cavity is provided inside the left roller and the right roller, an extrusion block groove is provided inside the left roller near the edge of the right roller, and an extrusion block groove is also provided inside the right roller near the edge of the left roller. The roller in the metal lithographic offset printing impression roller is easy to install and remove, and the separation and matching of the roller and the locking sleeves at both ends can be achieved by separating and embedding the key block on the locking block and the key groove on the locking sleeve, which is convenient for maintenance and replacement of the roller, and the working part on the side wall of the roller is the roller sleeve, which is installed and replaced by unscrewing the spiral ring block. Since the thickness of the metal plate varies, a roller sleeve of matching thickness can be selected according to the specific situation to make it more stable during printing.

[0004] It can be seen from the above-mentioned public scheme that the current embossing roller and the embossing roller shaft are fixedly installed, and it is not easy to install embossing rollers of different styles on one shaft, which brings a lot of inconvenience to use. At the same time, multiple parts need to be loaded and unloaded when installing the shaft, which is not only troublesome but also inefficient. Utility Model Content
