The specific embodiment
Operation principle of the present utility model is as follows: reel unwinding device 1 is by 9 controls of inflatable dispensing shaft.One end of inflatable dispensing shaft 9 is provided with lateral adjustments screw rod 10, the spool that is used to regulate unwinding device 1 is to the position, and the other end is equipped with magnetic powder brake 11, makes paper produce certain tension force, its tension force size is carried out by program constant tension controller or closed loop controller, reaches big volume and rouleau uniform tension in order.Deviation correcting device 12 is arranged on unwinding device 1 top, and when blowing had skew in running, the correction photometer head sent signal, and low-speed synchronous motor swings the correction axle just according to the sense command running by ball-screw, reaches the purpose of correction.
Process correcting set, photoelectric error correction device adopt Italian Re servomechanism installation and photometer head, band meta hold function, and accurate positioning is reliable.
First draw-gear 2 is made up of traction pair roller 13, pressing cylinder 14 and transmission system 15, the traction pair roller is that two pair rollers of a glue one steel are formed, wherein draw the steel rider diameter and become integral multiple with the printed matter circular pitch, transmission system 15 is differential gear reductor and power transmission shaft, and pressing cylinder 14 provides enough traction pressures for carry-over pinch rolls 13.
Dancer in the register sets 3 can realize that the secondary of die cutting mechanism and printed matter chases after the high accuracy of India and China to version, this mechanism is by unsteady roller 16, ball-screw 17 and to compositions such as version motors 18, ball wire 17 thick sticks can make the repetitive positioning accuracy of dancer remain in the 0.02mm, to reach the high accuracy secondary to version.
Second draw-gear 4 is identical with first draw-gear, 2 structures, and the group design has the two bare headed checkout gears 19 of gravure to carry out the contraposition detection in second draw-gear 4.
Rip cutting mechanism 5: in some printed matter, need vertically cut into several or trimming, carry out cross cutting, this wants the rip cutting group to finish,, rip cutting mechanism 5 comprises vertical rotor 29, cushion cover formula bottom roller 21, is installed in the vertical cutting knife 20 on the cushion cover formula bottom roller 21, leads paper tube 22, horizontal unified fine setting is housed, and edge strip is discharged by leading paper tube 22.
Disconnected cutting mechanism 6 adopts circle to press round disconnected cutting, and disconnected cutting mechanism 6 comprises pinch rollers 28, support roller 24, anvil roller 25, die cutting roller 26 and disconnected cutting knife 27.The pressure that pinch rollers 28 controls produce printed matter, support roller when the same indentation of the effect of support roller 24 is protruding, anvil roller 25 has quite high hardness, wear resistance and surface smoothness, the diameter of die cutting roller 26 identical with plate cylinder or 2 times to forme, can change fast, disconnected cutting knife 27 is finished cut-out work.
The finished product that is completed for printing is collected by collection paper platform 8.
