Abstract
The invention discloses an automatic on-off pressure device of an offset press. An impression cylinder, a rubber cylinder, a plate cylinder and an on-off pressure shaft are mounted between and on left and right wallboards, a driver is mounted at one end of the on-off pressure shaft and is fixed on the left wallboard and the right wallboard through a support shaft, shaft heads at two ends of the rubber cylinder are symmetrically provided with a left eccentric sleeve and a right eccentric sleeve, a left gear block and a right gear block are mounted on the left eccentric sleeve and the right eccentric sleeve, and a left gear and a right gear which are meshed and rotate are mounted on the left gear block and the right gear block. The driver directly drives the on-off pressure shaft to move, adjustment of printing pressure of the rubber cylinder and the impression cylinder is realized, automation level is high, cost is low, mechanical performance is reliable and stable, printing assisting time is short and labor intensity is thereby reduced.
Description
Technical field:
The present invention relates to a kind of offset press automatic clutch pressure device, be specially adapted to the adjusting of blanket cylinder and impression cylinder squeegee pressure.
Background technology:
Clutch pressure device on existing offset press, to regulate blanket cylinder and plate cylinder, the adjusting of impression cylinder pressure, its structure is: two eccentric bushings are housed between blanket cylinder spindle nose and wallboard hole, on outer eccentric bushing (outer eccentric bushing), pass through sector, gear, fulcrum, adjusting rod, the parts such as handle are manually adjusted 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 are controlled blanket cylinder and plate cylinder, the combined pressure of impression cylinder and tripping action.Its shortcoming is: mechanism's complexity, accumulation mismachining tolerance and rigging error are larger, thereby affects the serviceability of machine, and because parts are many, cost is high, and artificial intensity is large, and printing is long non-cutting time.
Summary of the invention:
Task of the present invention is that a kind of cost of proposition is low, reduces labour intensity, and simple in structure, machine performance is stable, reliable a kind of offset press automatic clutch pressure device.
Task of the present invention 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, left and right tooth piece is installed on described left and right eccentric bushing, the left and right gear that engagement is rotated is housed on left and right tooth piece.The optional servomotor of described driver, stepper motor and electric rotating machine, the motor shaft on servomotor can link together by key and clutch last item.Described left and right tooth piece and left and right eccentric bushing are fixed together by screw.Described left and right gear is the two ends that are assemblied in clutch last item, and described gear can be gear, helical gear.
The present invention has following effect: this structure adopts driver, directly drives clutch last item to move, and realizes the adjusting of blanket cylinder and impression cylinder squeegee pressure, automaticity is large, and cost is low, and machine performance is reliable, stable, printing is short non-cutting time, thereby reduces labour intensity.
Accompanying drawing explanation:
The front view of the eccentric bushing of Tu1Shi Ben mechanism; Fig. 2 is the front view of eccentric bushing and gland combination; Fig. 3 is that A for Fig. 2 and Fig. 3 is to view.
Drawing explanation: 1, plate cylinder, 2, blanket cylinder, 3, right tooth piece, 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 piece, 15, right wallboard, 16, left wallboard.
The specific embodiment:
The technical program is, in clutch last item 8 one terminations, driver 4 is directly installed, directly drive clutch last item to rotate, thereby the left and right gear 10,7, left and right tooth piece 14,3, the engagement that drive the assembling of clutch last item two ends are rotated and are changed blanket cylinder center, it is the combination that adopts excentric sleeve 11,9, capacity eccentric bearing and left and right gland 13,12, thereby realize tripping and the combined pressure of blanket cylinder and plate cylinder 1, impression cylinder 5, by its rotation of driver control and the trace that carries out amount of spin, regulated.
Specific embodiment is as follows:
As Fig. 1, shown in Fig. 2, a left side, 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., take servomotor as example, and the motor shaft on servomotor can link 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 a left side is installed, right tooth piece 14, 3, a described left side, right tooth piece 14, 3 are fixed together by screw with left and right eccentric bushing, a left side, the left side that engagement is rotated is housed on right tooth piece, right gear 10, 7, a described left side, right gear is the two ends that are assemblied in clutch last item, and described gear can be gear, helical gear etc., a left side, right tooth piece can be respectively and a left side, right gear is corresponding is spur gear, helical gear, a left side, right gland 13, 12 are placed on a left side, right wallboard 16, in 15 hole, 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, namely servomotor work of driver 4, drive the left and right gear 10 assembling on clutch last item, 7 rotate, thereby drive left, right tooth piece 14, 3, left, right eccentric bushing 11, 9 around a left side, right wallboard 16, 15 hole center rotating, thereby change the center of blanket cylinder, when needs blanket cylinder 2 and plate cylinder 1 and impression cylinder 5 combined pressure, blanket cylinder 2 centers are near having respectively certain pressure between plate cylinder 1 and impression cylinder 5, when needs blanket cylinder 2 and plate cylinder 1 and impression cylinder 5 tripping, between blanket cylinder 2 and plate cylinder 1 and impression cylinder 5, there is respectively certain gap, by controlling driver 4(servomotor) quit work, so just can realize blanket cylinder 2 by a rear program electric automatic control moves with combined pressure and the tripping of plate cylinder and impression cylinder 5, when as needs, to blanket cylinder 2, pressure regulates during with impression cylinder 3 combined pressure, only need by electric program, the amount of spin of driver (servomotor) to be carried out suitably regulating, this device is easy to use, simple and direct, thereby reduced hand labor intensity.
