Description

Technical Field

[0001] The utility model belongs to the technical field of printing machines, in particular to an adjustable tension type printing machine. Background Art

[0002] A printing press is a machine that prints text and images. It is one of the most important equipment in a modern printing plant. Its main function is to transfer ink to the substrate to complete the production of printed products. There are many types of printing presses, which can be divided into many types according to different classification standards such as printing plate type, printing method, printing material, printing color, etc.

[0003] The working principle of a printing press is as follows: first, the ink is evenly applied to the printing plate through the inking device, and then the ink on the printing plate is transferred to the substrate through the pressure device. In this process, various mechanisms and systems of the printing press work together to ensure the quality and production efficiency of the printed product.

[0004] For example, a Chinese patent with publication number CN209454341U discloses a new type of printing machine, which aims to provide a new type of printing machine with the advantages of being able to automatically cut paper after printing is completed, avoiding manual transportation to the next unit, improving the overall degree of automation, and optimizing production efficiency. The key points of its technical solution are that a cutting unit is provided on the side of the machine body away from the paper feeding cylinder, the cutting unit includes a cutting table and a transition roller for conveying paper to the cutting table, a cutting knife for cutting paper and a timing drive mechanism for controlling the cutting knife to slide back and forth toward the cutting table to cut paper at a timed interval, the timing drive mechanism includes a timing gear linked to the transition roller, a timing wheel rotatably connected to the machine body, and a timing rod connected between the timing wheel and the cutting knife for controlling the movement of the cutting knife under the action of the timing wheel, which can automatically cut the paper after printing is completed, avoiding manual transportation to the next unit, improving the overall degree of automation, and optimizing production efficiency.

[0005] The above patent has the following problems:

[0006] This patent has some disadvantages when in use, such as: the above printing machine cannot adjust the tension of the paper when in use. When the tension of the paper is too small, the printed material may become loose or even wrinkled, resulting in an uneven surface of the printed product, which affects the product quality. In view of this, we propose an adjustable tension printing machine. Utility Model Content
