Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a printing roller adjusting device for printing equipment. Background Art

[0002] A printing press is a machine used to print text and images. Modern printing presses generally consist of mechanisms such as plate loading, inking, embossing, and paper feeding. Its working principle is as follows: the text and image to be printed are first made into a printing plate and mounted on the printing press. Ink is then applied to the areas of the plate where the text and image are located, either manually or by the printing machine. The ink is then directly or indirectly transferred to paper or other substrates, producing a printed product identical to the printing plate.

[0003] The printing roller is one of the main components commonly found in printing presses. It is usually made of materials such as metal or rubber and plays an important role in the printing process.

[0004] For example, the prior art Chinese patent publication number "CN217227010U" provides a pressure adjustment mechanism of a printing press, including a machine body, in which a rotatable printing roller and a pressure roller for pressing the printed matter are arranged. The pressure roller and the printing roller are arranged in parallel, and a movable groove is formed through the side walls of the machine body near both ends of the printing roller. The movable groove is arranged obliquely downward, and the highest end of the movable groove is arranged near the printing roller. A rotating wheel is fixedly connected to both ends of the pressure roller, and the two rotating wheels are respectively arranged in two movable grooves. The rotating wheels can move along the length direction of the movable groove, and a fixing component for fixing the position of the pressure roller is provided on the side wall of the rotating wheel away from the pressure roller.

[0005] The device has the effect of facilitating the adjustment of printing pressure.
