Technical Field

The invention relates to a flexible printing press, in particular to a plate roller component of the flexible printing press.

Background

The flexographic printing machine has the advantages of simple machine structure, strong material adaptability, small imprinting force, low printing cost, high printing speed, good quality, environmental protection and the like. The plate roller component of the prior art flexographic printing machine has the following disadvantages: the printing roller can not realize independent clutch pressure control, and the printing roller is simultaneously separated from the anilox roller and the stamping roller when the printing roller is stopped, so that ink on the printing roller is easy to dry when ink is printed, the re-starting printing can be influenced under the condition that effective treatment cannot be obtained, and in addition, the structure for adjusting the printing pressure of the printing roller in the prior art is also complex.

Disclosure of Invention

In view of the defects of the prior art, the invention aims to provide a printing plate roller component of a printing machine, which can ensure that the printing plate roller and an anilox roller are contacted before a stamping roller is separated during shutdown, the ink on the printing plate roller is printed for several more times to consume the ink on the printing plate roller, and then the printing plate roller is separated from the stamping roller.

In order to solve the technical problems, the invention adopts the following technical scheme to complete:

printing machine version roller part locates the version roller of anilox roller and embossing roller top including the printing during operation, and the inboard swing of frame wallboard is equipped with carries out the petal body about supporting to the front and back axle head of version roller, its characterized in that: the lower parts of the left petal body and the right petal body are connected with a frame wallboard in a swinging mode, the left petal body and the right petal body are pushed by respective front and rear clutch pressing mechanisms to carry out independent clutch pressing adjustment on the printing roller, and when the clutch pressing mechanisms act, the printing roller can be in contact with the anilox roller before the embossing roller is disengaged. Clutch pressure mechanism includes clutch cylinder, voussoir, slider and pin, and clutch cylinder installs on the frame wallboard, and the frame wallboard is equipped with horizontal spout, and in the spout was located to the slider horizontal activity, the medial surface of slider was relative with the pin, the lateral surface was equipped with the inclined plane and the voussoir is relative, and the pin joint is on the upper portion of the petal body, and the dead weight that the pin relied on the petal body compresses tightly on the slider, and the voussoir freely passes in and out the spout is promoted by clutch cylinder.

By adopting the technical scheme, the invention can realize the independent clutch pressure control of the plate roller, the contact between the plate roller and the anilox roller is released before the stamping roller when the printing machine is stopped, the printing ink on the plate roller is printed for a plurality of more plates to consume the printing ink on the plate roller, and then the plate roller is separated from the stamping roller, so that the problem that the printing ink cannot be processed on the surface of the plate roller and is easy to dry is solved, and the start-up printing is not influenced. The specific action process of the clutch pressure is as follows: when the machine is stopped, the front clutch pressing mechanism and the rear clutch pressing mechanism on one side of the left petal body (anilox roller) firstly act, the clutch cylinder pushes the wedge block to move forward, the wedge block pushes the sliding block to slide transversely, the sliding block pushes the pin to act, and the pin enables the left petal body to swing upwards, so that the left petal body lifts the printing roller upwards from the bottom of the left side in a single edge direction, the printing roller is separated from the contact with the anilox roller, and the printing roller is still in contact with the stamping roller at the moment; the plate roller continues to rotate, ink on the plate roller is used up quickly, at the moment, the front clutch pressure mechanism and the rear clutch pressure mechanism on one side of the right petal body (stamping roller) act, the clutch cylinder pushes the wedge block to move forward, the wedge block pushes the sliding block to transversely slide, the sliding block pushes the pin to act, and the pin enables the right petal body to swing upwards, so that the right petal body lifts up the plate roller from the bottom of the right side in a single-side mode, the plate roller is separated from contact with the stamping roller, the plate roller stops rotating, single clutch pressure control of the plate roller is achieved, and the structure is simple.

Preferably, the printing pressure of the printing roller is independently adjusted by a pressure adjusting mechanism, the pressure adjusting mechanism comprises an adjusting screw, the adjusting screw is manually adjusted by an adjusting hand wheel, one side of the tops of the left petal body and the right petal body is provided with a leaning surface, and the leaning surface presses the adjusting screw by the self weight of the petal body. Through the design, when the position of the adjusting screw on one side of the left petal body or the right petal body is independently adjusted manually, the contact pressure between the printing roller and the anilox roller or the stamping roller can be changed to adjust the printing pressure of the printing roller, and the structure is very simple.
