Description

Technical Field

[0001] The present application relates to the technical field of printing press equipment, and in particular to a pressure regulating mechanism of a printing press. Background Art

[0002] A printing press is a machine used to print text and images. It can not only reproduce text and images efficiently, but also select appropriate printing technology and materials according to different needs. In order to ensure printing quality and efficiency while protecting the equipment itself, the pressure adjustment mechanism of the printing press needs to be used during the adaptation process of the printing press.

[0003] When processing paper of different thicknesses, the pressure adjustment mechanism of existing printing machines often cannot accurately adjust the applied pressure according to the specific thickness of the paper, and cannot ensure that each piece of paper can be unrolled with appropriate pressure. This uneven pressure application not only affects the printing quality, but may also cause wrinkles on the paper after unrolling. In addition, since the pressure adjustment mechanism fails to effectively adjust the applied pressure for paper of different thicknesses, the flatness of the paper after unrolling is not satisfactory. Paper with low flatness will reduce the overall texture of the printed product and affect the user experience.

[0004] Therefore, in order to solve the above problems, the present application provides a pressure adjustment mechanism for a printing press.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
