Description

Technical Field

[0001] The utility model relates to the technical field of printing, and belongs to a printing roller multi-tone adjustment mechanism. Background Art

[0002] A machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate mounting, inking, embossing, and paper feeding. Its working principle is: first, the text and image to be printed are made into a printing plate, mounted on a printing press, and then the ink is applied to the places with text and images on the printing plate by humans or a printing press, and then directly or indirectly transferred to paper or other substrates, thereby replicating the same printed product as the printing plate. The invention and development of printing presses play an important role in the spread of human civilization and culture. When printing, it is necessary to use basic inks of basic colors such as red, yellow, and blue and other auxiliary materials in advance to mix and adjust the color to form the required color. During the color adjustment process, the ratio between the basic inks is closely related to the final color formed. When the amount of ink of a certain color is too much, it will cause the final color to deviate from the required color.

[0003] Current printing devices lack a convenient color adjustment mechanism, which makes color adjustment during the printing process extremely inconvenient. When the color needs to be changed, the staff needs to replace the ink cartridge and perform a series of operations, which is time-consuming and labor-intensive. In addition, during the color adjustment process, the color tone is usually controlled by the amount of ink on the printing roller, but the problem of difficult control of ink output may occur, resulting in unstable ink amount on the printing roller and poor color tone.

The driving shaft 521 is fixedly connected to the multi-color ink supply cartridge 51 through an axial hole. The output end of the second motor 522 is connected to one end of the driving shaft 521 through a coupling. The second motor 522 can control the rotation of the multi-color ink supply cartridge 51, thereby replacing inks of different colors. A connecting sleeve 523 is provided on the driving shaft 521, and the connecting sleeve 523 is rotatably connected to the driving shaft 521. A connecting beam 524 is provided on the upper end of the second bracket 4, and an electric telescopic rod 525 is provided on the connecting beam 524. The output end of the electric telescopic rod 525 is connected to the connecting sleeve 523. The connecting beam 524 is used to form a support for the multi-color ink supply cartridge 51. While the electric telescopic rod 525 forms a connection between the multi-color ink supply cartridge 51 and the connecting beam 524, it can drive the multi-color ink supply cartridge 51 to move radially.

[0025] See also Figure 2 Specifically, a slide groove 41 is provided on the second bracket 4, and a slider 526 is provided on the driving shaft 521.

A ball seat 552 is connected to the ink outlet tube 551, and a ball 553 is arranged in the ball seat 552. The ball 553 is movably connected to the ball seat 552. The ball 553 rotates, which is beneficial to the uniform adhesion of the ink layer and can also control the ink output.

[0029] The working principle of the utility model is as follows: different ink separation areas 53 store inks of different colors. When it is necessary to replace inks of different colors, the second motor 522 drives the driving shaft 521 to rotate, thereby controlling the multi-color ink supply box 51 to rotate, and the different ink separation areas 53 are directed toward the printing roller 3, so as to replace inks of different colors; during the ink discharge process, the electric telescopic rod 525 drives the driving shaft 521 to approach the printing roller 3, thereby driving the multi-color ink supply box 51 to approach the printing roller 3, until the ink discharge head 55 is pressed onto the surface of the printing roller 3, the ball 553 on the ink discharge head 55 shrinks due to the pressure, and the push support member 554 moves upward, thereby the spring 5 56 is compressed, the limiting column 556 moves upward, opens the ink outlet tube 551, and the ink flows out through the ink outlet tube 551. At the same time, the printing roller 3 is driven by the first motor 31 to rotate, and the ink is attached to the printing roller 3. During this process, the ball 553 rotates, which is beneficial to the uniform adhesion of the ink layer and can also control the ink output. To control the thickness of the ink layer on the printing roller 3, the pressure between the ink outlet head 55 and the printing roller 3 can be adjusted by adjusting the displacement of the multi-color ink supply cartridge 51, thereby adjusting the outlet size between the limiting column 556 and the ink outlet tube 551 and the gap size between the ball 553 and the ball seat 552, thereby changing the ink output.
