Abstract
The invention relates to an adjusting device for paper feeding length between printing unit points of a multicolor offset printer, which comprises a plurality of fixed printing units in sequential arrangement. The device is characterized in that an adjusting tension roll driven by a servo driving mechanism is arranged between each two adjacent fixed printing units, fixed driven rolls are fixed to two sides of each adjusting tension roll, and the servo driving mechanism is connected to an offset printer control system. Paper sequentially passes through the front fixed driven roll, the adjusting tension roll and the rear fixed driven roll. When the paper needs to be adjusted, positions of the adjusting tension rolls can be altered through the servo driving mechanism to change paper feeding length between each two adjacent printing unit points to meet integer multiple of printing format, and accordingly the overprinting requirements on precision can be met.
Description
Technical field
The present invention relates to a kind of multicolour offset press, paper feed length adjuster between particularly a kind of multicolour offset press printing element point.
Background technology
Rotary offset machine needs to change between adjacent printed units point and walks paper length when carrying out the printing of polychrome luffing, makes it walk the integral multiple that paper length is the printed matter breadth, otherwise can't realize polychrome printing.
The printing element dot spacing of present rotary offset machine adopts the method for mobile printing unit to realize from the paper feed length adjustment; Its shortcoming is: the heavy packages offset press is because the door width of cloth is big, speed is high; And the stability in the use etc. is had relatively high expectations; Therefore be not suitable for adopting the method for mobile printing unit, the scope of application receives certain restriction.
Summary of the invention
The technical problem that the present invention will solve provides paper feed length adjuster between the high multicolour offset press printing element point of a kind of stability.
For solving the problems of the technologies described above; Technical scheme of the present invention is: paper feed length adjuster between a kind of multicolour offset press printing element point; Comprise the fixing printing unit that several are arranged successively; Its innovative point is: be provided with the adjustment idler roller that is driven by servo-actuating device between the said adjacent fixing printing unit, said adjustment idler roller both sides are provided with fixedly driven voller, and said servo-actuating device inserts offset press control system.
The invention has the advantages that: paper passes through fixedly driven voller of last fixedly driven voller, adjustment idler roller and back one successively; In the time of need adjusting; Only need to change the position of adjustment idler roller through servo-actuating device; Make the paper length of walking between adjacent printed units point change, make its integral multiple that satisfies printing format, thereby reach the required precision of chromatography.
Description of drawings
Fig. 1 is paper feed length adjuster structural representation between multicolour offset press printing element point among the present invention.
The specific embodiment
As shown in Figure 1, comprise fixing printing unit 1, fixing printing unit 2, fixing printing unit 3, adjustment idler roller 4, fixedly driven voller 5, fixing driven voller 6.
Arrange successively in said fixing printing element 1,2,3 front and back; Be provided with the adjustment idler roller 4 that drives by servo-actuating device between the adjacent fixing printing unit; The both sides, front and back of adjustment idler roller 4 are provided with fixedly driven voller 5,6, and servo-actuating device inserts offset press control system.
