Description

Multicolor press no-stopping printed matter deflection adjustment mechanism

Technical field

The utility model relates to a kind of multicolor press no-stopping printed matter deflection adjustment mechanism.

Background technology

At present, the crooked adjustment mode of multicolour press has two kinds: a kind of is to shut down crooked adjustment, and another kind is not shut down the printed matter deflection adjustment.Shut down crooked adjustment and be mostly that long to the version time, positioning accuracy is not high by operative employee's manual operation, the adjustment production efficiency of this mode is lower; Do not shut down the printed matter deflection adjustment and have plenty of by the angle of regulating the forme clamp bar and adjust the crooked of forme, this mode easily causes the site ghost image and produces waste product that percent defective is higher relatively.What have then is to make the run-off the straight of plate cylinder axis regulate the crooked purpose of forme to reach by regulating the one-sided eccentric bushing of plate cylinder, this mode then causes easily by the version ink roller and changes with the printing that plate cylinder pressure and plate cylinder cause with pressure variation between the blanket cylinder, is difficult to reach the requirement of high-grade printing.

The utility model content

The technical problems to be solved in the utility model is at above-mentioned defective; providing a kind of need not change by pressure between version ink roller and the plate cylinder and the pressure between plate cylinder and the blanket cylinder; the rate of reducing the number of rejects and seconds is adjusted rapidly multicolor press no-stopping printed matter deflection adjustment mechanism reliably.

In order to solve the problems of the technologies described above; the utility model provides a kind of multicolor press no-stopping printed matter deflection adjustment mechanism of following structure; comprise operating surface wallboard and the transfer drum between impression cylinder and two transfer drums; the drum shaft of one transfer drum is connected with printing press wall board; the angular bisector of the angle that the line of centres of the line of centres of an impression cylinder and a transfer drum and a transfer drum and two transfer drums forms is defined as Y-axis; its design feature is: the link of the drum shaft of a described transfer drum and operating surface wallboard is equipped with movable sleeve; the operating surface wallboard is provided with through hole; movable set also can be moving along y-axis shift at through hole in through hole; be fixed with on the operating surface wallboard and can make movable sleeve along the moving guider of y-axis shift; the movable sleeve top is provided with and drives movable sleeve along the moving slippage driving mechanism of y-axis shift, and the movable sleeve below is provided with the resilient supporting unit that supports movable sleeve along Y direction.

The utility model makes paper produce certain angle in transmittance process by regulating the one-sided paper amount size of holding in the month of a transfer drum in the machine operation procedure, to reach the purpose that printed matter deflection is adjusted.The utility model is changed into printing machine one transfer drum one side by the rigid bearing cover can be along the moving movable sleeve of y-axis shift, make the relative adjacent roller axis tilt of transfer drum axis certain angle, changed the one-sided paper amount size of holding in the month of a transfer drum, paper one-sided paper amount of holding in the month in transmittance process is changed, aligning is treated red ink paste used for seals picture group literary composition position, finishes the printed matter deflection adjustment.In the printing process if find printed matter deflection; under non-stop-machine state; control device instruction slippage driving mechanism action by printing machine; the slippage driving mechanism orders about movable sleeve and slides downward or upward along guider; thereby change the one-sided paper amount size of holding in the month of a transfer drum, resilient supporting unit can guarantee that the every bit that is actively set on sliding scale all is in stable status.Because the crooked adjustment of the utility model multicolor press no-stopping printed matter deflection adjustment mechanism printing product realizes by changing the one-sided paper amount size of holding in the month of a transfer drum; therefore can not change by pressure between version ink roller and the plate cylinder and the pressure between plate cylinder and the blanket cylinder; the rate of reducing the number of rejects and seconds, and it is simple to adjust rapid reliable operation.
