Abstract
The utility model provides an effective device which can automatically realize the disengaging and engaging pressure of an offset press. A detection signal is input to an electric control part by a photoelectric detection part; instructions are then sent to an electromagnet control mechanism by the electric control part. The pickup of the electromagnet pushes through an ejector pin by the swing of a lever and lays down an African fish when an engaging pressure power rod provides the power for the African fish, thus pushing a control rod to drive the eccentric shaft of a glue roller so as to generate a turnover action and realize the engaging pressure. When a no-paper signal exists, the electromagnet acts again, the ejector pin pushes through a large-head screw which hangs on a control wedge and leads the large-head screw to be disconnected, and the glue roller recovers the original position under the action of a control rod recovery spring. The effective device which can automatically realize the disengaging and engaging pressure of an offset press has simple and smart structure and reliable function.

The specific embodiment
As shown in Figure 1, paper is transported on the paper bridge by paper feeding mechanism, whether photoelectric detection mechanism detects paper, to judge that signal flows to electric control system, control section sends instruction for the electromagnet in the mechanical actuating mechanism, adhesive and disconnection by electromagnet come the driving device clutch pressure mechanism, thereby realize the clutch pressure-controlled.
As shown in Figure 2, in the photoelectric detection system, supporting traverse 1 both sides are installed on the machine wallboard, and Photoelectric Detection probe 2 sends infrared light, and when having paper to pass through, infrared light is reflected by paper when following, and the probe recipient obtains signal, flows to electric control system; When following no paper, infrared light is not reflected, and probe is done no paper signal processing, flows to electric control system equally.
As shown in Figure 3, in the clutch piezoelectricity magnet controlling organization, when electrical control division was given electromagnet 3 and sent instruction, electromagnetic actuation pushed the clutch bar 7 that bears down on one by action lever 6 and does axial motion; When electromagnet outage, the clutch bar that bears down on one sets back under the effect of back-moving spring 1.Electromagnet 3 is installed on the support 5, is fixed on together on the wallboard 4, and action lever 6 can be swung around supporting revolving shaft 2.
As shown in Figure 4, in the clutch pressure actuator (combined pressure state), when electromagnet 6 adhesives, the clutch bar string moving 8 that bears down on one, drive control pin 10 and loosen control guide rail 11, African flake 12 rides in the guide-track groove, drives African fish 17 downward beats thereupon, at this moment, along with rotating counterclockwise of impression cylinder axle 14, combined pressure power cam 13 high points push combined pressure bearing 15, drive combined pressure power rail 16 swing counterclockwise, the power rail head withstands on African fish mouth 17, makes it produce the left-hand setback.Control lever 3 is installed on the glue cylinder eccentric shaft 18, the motion of Africa fish 17, push lever 3 produces flip-flop movement, drive fork 5 dextrad forward travels, under the effect of spring leaf 4 thrusts, major part screw 9 is just in time hided and is tangled on the inclined-plane of control skewback 7, and this moment, glue cylinder and impression cylinder, plate cylinder were drawn close the generation combined pressure simultaneously.During combined pressure, three cylinders are combined pressure in the cylinder breach, its accurately the combined pressure time comprehensively determine by photoelectric probe signal and action of cam time, avoid producing clutch in advance and press or produce overvoltage.
As shown in Figure 5, in the clutch pressure actuator (tripping state), when no paper signal, electromagnet 7 adhesive once more, the clutch bar 9 that bears down on one pushes major part screw 6 and throws off control skewbacks 8 inclined-planes, control lever 3 drives 4 deflections of glue cylinder eccentric shaft and resets under the pulling force of back-moving spring 1, arrives till the tripping limited post 2 always.At this moment, the control guide rail lifts under the effect of reduction torsion spring and resets, and drives African fish 11 and also lifts simultaneously, and combined pressure power rail 15 is done reciprocal idle stroke swing with power cam 13 under the effect of reduction torsion spring.
