Description

Technical Field

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

[0002] A printing press is a machine used to print text and images. Its working principle is to make the text and images into a printing plate, then use an ink roller to transfer ink to the printing plate, and then use an impression roller to compact the printing plate and printing materials, and finally transfer the text and images to paper or other substrates. Printing presses play an important role in the printing industry and are widely used in commercial printing, publishing printing, packaging printing and other fields.

[0003] Printing rollers are an indispensable part of the printing process. They undertake important tasks such as transferring printing materials, compacting printing plates and printing materials. Printing rollers can transfer printing materials and ink to printing plates, ensuring that the text and images on the printing plates can be accurately printed on the substrate. They can also compact printing plates and printing materials to ensure the quality of printing results.

[0004] During the printing process, the distance between the printing rollers is a factor that affects the printing effect, so the distance between the printing rollers needs to be adjusted. In addition, the amount of ink in the ink cartridge changes during use, which will cause the amount of ink on the printing roller to be inconsistent, resulting in inconsistent printing effects of the printed products, affecting the quality of the printed products. Therefore, the position of the printing roller and the ink cartridge needs to be adjusted to overcome this situation. Utility Model Content
