Compared with the prior art, the utility model can realize the precision adjustment for pressure; meanwhile, the pressure of both ends can be adjusted synchronously with simple convenient adjustment after adopting the numerical controlled pressure regulation appliance of the offset press.
Description
Technical field:
The utility model relates to a kind of numerical controlled voltage device, particularly a kind of offset press numerical controlled voltage device.
Background technology:
In the prior art, the metallic plate offset press is made up of feeding part, pusher part, water supply part, ink guide part, printing, discharging.Metallic plate in heaps partly is separated into one by one metallic plate and is sent to the pusher part by feeding; The pusher part positions the metallic plate that feeding partly joins, and gives the impression cylinder of printing stably; Be equipped with one on the impression cylinder and arrange the mechanism of gritting one's teeth, grit one's teeth and bite metallic plate that pusher portion sends here and bring between impression cylinder and the rubber and print, arrive the output section at last, the picture and text that transfer printing is come from the plate cylinder are arranged on the rubber cylinder, by roll extrusion picture and text have been transferred on the metallic plate, have finished whole printing process with impression cylinder.Wherein, the printing of offset press is made up of plate cylinder, rubber cylinder, impression cylinder and clutch pressure mechanism, pressure regulating mechanism.Forme is housed on the plate cylinder, forme surface picture and text are partly accepted the China ink layer that ink guide part transmits, and the China ink layer is transferred to the rubber cylinder surface transfer on the metallic plate at last, in the transfer process of ink lay, in order to make the picture and text part on the forme complete truly indeformable, abundant is transferred on the metallic plate, the water route part between damping roller and the forme, between the inking roller and plate cylinder of China ink road part, between plate cylinder and the rubber cylinder, all suitable juxtaposition metamorphose to be arranged between rubber cylinder and the impression cylinder, promptly produce certain pressure, in above-mentioned several pressure, because the difference of stock plate thickness, the rubber cylinder adjusted and the pressure between the impression cylinder are changed, therefore when the metallic plate of printing different-thickness, often need to adjust the pressure between impression cylinder and the rubber cylinder aborning.Can regulate in order to make the pressure between impression cylinder and the rubber cylinder, rubber cylinder or impression cylinder are installed in the eccentric trepanning, the eccentric bushing cylindrical is installed in the fixing wallboard hole, pressure regulating mechanism is fixedly rotating a certain angle in the wallboard hole by making eccentric bushing, when eccentric bushing rotates, changing between the another one cylinder of mutual roll extrusion such as the position that is installed in the cylinder in the eccentric trepanning changes reaches pressure controlled purpose.In the prior art, metallic plate offset press and tin graphed sheet machine all adopt the mode of manual adjustments, make eccentric bushing produce rotation by certain frame for movement and regulate pressure.The shortcoming that Manual pressure is regulated is: the variation of pressure is difficult to grasp during adjusting, often needs to determine actual pressure by the mode of actual measurement, and the adjusting time is long; Because the factor of element precision and distortion, the pressure at two ends is difficult to guarantee in full accord.
Summary of the invention:
Technical problem to be solved in the utility model is: there is following shortcoming in existing offset press regulator: the size that 1, is difficult to accurately control to adjust pressure; 2, the size that needs observed pressure, the adjusting time is long; 3, pressure at two ends is difficult to consistent adjusting the synchronously.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to provide a kind of offset press numerical controlled voltage device, described offset press numerical controlled voltage device is by PLC (programmable logic controller (PLC)), stepper motor constitutes with the transmission mechanism that is connected eccentric bushing, wherein, described PLC (programmable logic controller (PLC)) is connected with described stepper motor, the output shaft of described stepper motor connects with the described transmission mechanism that is connected eccentric bushing, concrete, the transmission mechanism of described connection eccentric bushing is by worm screw, worm gear, screw axis, encoder, the screw mandrel cover, first mandrel, second mandrel, the 3rd mandrel, first connecting rod, second connecting rod, eccentric bushing and pendulum pin constitute, the output shaft of described stepper motor and described worm screw interconnect, the center line of the output shaft of described stepper motor and the center line of described worm screw overlap, described worm screw and described worm gear cooperatively interact, the center line of described worm screw is vertical mutually with the center line of described worm gear, described worm gear is arranged on the described screw axis, can be between described worm gear and the described screw axis for being threaded, the center line of described worm gear and the center line of described screw axis overlap, further, on described screw axis, also be provided with described encoder, described encoder can be fixed on the described screw axis by screw, described encoder can be angular transducer, described screw axis and described screw mandrel cover cooperatively interact, described screw mandrel cover is by described first mandrel and described first connecting rod and second connecting rod flexible connection, concrete connected mode can be for hinged, one end of described first connecting rod flexibly connects by described second mandrel and described eccentric bushing, concrete connected mode can be for hinged, described second connecting rod flexibly connects by described the 3rd mandrel and described pendulum pin, concrete connected mode can be for being articulated and connected, and described pendulum pin is fixed on the frame.
The utility model and prior art contrast, because used offset press numerical controlled voltage device, when can realize the accurate adjusting to pressure, pressure at two ends is consistent the adjusting synchronously, regulates simple and convenient.
