Description
Technical field:
The utility model relates to a kind of offset press automatic clutch pressure device, is specially adapted to the adjustment of blanket cylinder and impression cylinder squeegee pressure.
Background technology:
Clutch pressure device on existing offset press, regulate blanket cylinder and plate cylinder, the adjustment of impression cylinder pressure, its structure is: two eccentric bushings are housed between blanket cylinder spindle nose and wallboard hole, outer eccentric bushing (outer eccentric bushing) passes through sector, gear, fulcrum, adjusting rod, the parts such as handle manually adjust the pressure between blanket cylinder and impression cylinder respectively, an eccentric bushing (interior eccentric bushing) of the inside passes through connecting rod, clutch last item, fork, fulcrum, swing span, roller, the parts such as cam control blanket cylinder and plate cylinder, the combined pressure of impression cylinder and tripping action.Its shortcoming is: mechanism is complicated, accumulation mismachining tolerance and rigging error larger, thus affect the serviceability of machine, and due to parts many, cost is high, and greatly, it is long to print non-cutting time for artificial intensity.
Summary of the invention:
Task of the present utility model is that a kind of cost of proposition is low, and reduce labour intensity, structure is simple, and machine performance is stablized, reliable a kind of offset press automatic clutch pressure device.
Task of the present utility model completes like this, a kind of offset press automatic clutch pressure device, it is characterized in that: between left and right wallboard He on wallboard, impression cylinder, blanket cylinder, plate cylinder and clutch last item are installed, in clutch last item one end, driver is installed, driver is fixed on left and right wallboard by fulcrum, the two ends spindle nose symmetry of blanket cylinder is equipped with left and right eccentric bushing, described left and right eccentric bushing is provided with left and right tooth block, left and right tooth block is equipped with the left and right gear of engagement rotation.The optional servomotor of described driver, stepper motor and electric rotating machine, the motor shaft on servomotor can be linked together by key and clutch last item.Described left and right tooth block and left and right eccentric bushing are fixed together by screw.Described left and right gear is the two ends being assemblied in clutch last item, and described gear can be gear, helical gear.
The utility model has following effect: this structure adopts driver, and Direct driver clutch last item moves, and realizes the adjustment of blanket cylinder and impression cylinder squeegee pressure, automaticity is large, and cost is low, and machine performance is reliable, stable, printing is short for non-cutting time, thus reduces labour intensity.
Accompanying drawing illustrates:
Fig. 1 is the front view of the eccentric bushing of mechanism; Fig. 2 is the front view that eccentric bushing and gland combine; Fig. 3 is the A direction view of Fig. 2.
Drawing illustrates: 1, plate cylinder, 2, blanket cylinder, 3, right tooth block, 4, driver, 5, impression cylinder, 6, fulcrum, 7, right gear, 8, clutch last item, 9, right eccentric bushing, 10, left gear, 11, left eccentric bushing, 12, right gland, 13, left gland, 14, left tooth block, 15, right wallboard, 16, left wallboard.
Detailed description of the invention:
The technical program is directly provided with driver 4 in clutch last item 8 one termination, Direct driver clutch last item rotates, thus drive the left and right gear 10 of clutch last item two ends assembling, 7, left and right tooth block 14,3, engagement rotation changes blanket cylinder center, be adopt excentric sleeve 11,9, the combination of capacity eccentric bearing and left and right gland 13,12, thus realize blanket cylinder and plate cylinder 1, the tripping of impression cylinder 5 and combined pressure, by driver control, it rotates and the trace that carries out amount of spin regulates.
Specific embodiment is as follows:
As Fig. 1, shown in Fig. 2, left, right wallboard 16, between 15 He on wallboard, impression cylinder 5 is installed, blanket cylinder 2, plate cylinder 1 and clutch last item 8, in clutch last item one end, driver 4 is installed, driver 4 is fixed on left and right sidesing wall plate by fulcrum 6, furtherly: the optional servomotor of driver 4, stepper motor and electric rotating machine etc., for servomotor, the motor shaft on servomotor can be linked together by key and clutch last item, and the two ends spindle nose symmetry of blanket cylinder 2 is equipped with a left side, right eccentric bushing 11, 9, a described left side, the right avertence heart puts and is provided with a left side, right tooth block 14, 3, a described left side, right tooth block 14, 3 are fixed together by screw with left and right eccentric bushing, left, a left side for engagement rotation right tooth block is equipped with, right gear 10, 7, a described left side, right gear is the two ends being assemblied in clutch last item, and described gear can be gear, helical gear etc., left, right tooth block can respectively with a left side, right gear is corresponding is spur gear, helical gear, left, right gland 13, 12 are placed on a left side, right wallboard 16, in the hole of 15, for compressing a left side, right eccentric bushing.。
During work, when machine carries out tripping or combined pressure action, plate cylinder 1 is constant with the center of plate cylinder 5, driver 4 namely servomotor work, drive the left and right gear 10 that clutch last item assembles, 7 rotate, thus drive left, right tooth block 14, 3, left, right eccentric bushing 11, 9 around a left side, right wallboard 16, the hole center rotating of 15, thus change the center of blanket cylinder, when needs blanket cylinder 2 is with plate cylinder 1 and impression cylinder 5 combined pressure, there is certain pressure blanket cylinder 2 center respectively near between plate cylinder 1 and impression cylinder 5, when needs blanket cylinder 2 is with plate cylinder 1 and impression cylinder 5 tripping, blanket cylinder 2 and have certain gap respectively between plate cylinder 1 and impression cylinder 5, by control and drive system 4(servomotor) quit work, combined pressure and the tripping action of blanket cylinder 2 and plate cylinder and impression cylinder 5 so just can be realized by a rear program electric automatic control, as needs pressure when blanket cylinder 2 and impression cylinder 3 combined pressure is regulated time, only suitably need be regulated by the amount of spin of electric program to driver (servomotor), this device is easy to use, simple and direct, thus reduce hand labor intensity.
