Abstract
The utility model relates to a printing machinery, especially to an offset-press inking-roller pressure regulation device, including an eccentric wheel, a connecting rod, an inking-roller glue frame arm, a regulation axis, a first universal coupling, a universal linking rod, a second universal coupling and a worm gear pair. The connecting rod which is drove by the eccentric wheel drives the inking-roller glue frame arm to move. The regulation axis is arranged in the wall panel and is connected with the first universal coupling which is connected with the second universal coupling through the universal coupling rod, meanwhile the second universal coupling is connected with the worm rod. One end of eccentric wheel is arranged in the gear axis hole, and the eccentric wheel is drove to move by the worm gear pair. The utility model is compact in structure, good in self-lock, convenient and reliable in pressure regulation, and the utility model creates condition for appearance designation of printing unit.
Description
(1) technical field
The utility model relates to printing machinery, relates in particular to offset press inking roller pressure-regulating device.
(2) background technology
Inking roller pressure-regulating device in the existing offset press is to regulate the adjusting knob place the printing unit outside by operating personnel to pay to the pair of straight gear transmission of power and drive eccentric shaft and rotate, the eccentric shaft drivening rod moves inking roller glue boom by link motion and realizes the pressure adjustment of inking roller and plate cylinder.But in actual use, because adjusting knob is positioned at printing unit lateral surface support plate one end, with position, the inboard measuring pressure place of printing machine certain distance is arranged, the one man operation is very inconvenient when adjusting pressure.And support plate occupies very big position, and adjusting knob is an external again, has limited the improvement of unit appearance design.Adopt straight-tooth gear to pay transmission, adjust difficulty during its assembling, though locking function is arranged, the pressure phenomenon of walking about happens occasionally, and has influenced printing quality.
(3) summary of the invention
The utility model has overcome the defective of prior art, and a kind of novel inking roller pressure-regulating device is provided.The combining form that this inking roller pressure-regulating device employing universal coupling and gear on worm are paid, compact conformation, self-locking performance is good, and it is convenient, reliable to regulate pressure, and is that condition has been created in the appearance design of printing unit.
The utility model is achieved in that a kind of inking roller pressure-regulating device, comprise eccentric shaft, connecting rod, inking roller glue boom, the eccentric shaft drivening rod, connecting rod drives inking roller glue boom and moves, it is characterized in that this inking roller pressure-regulating device also comprises regulating shaft, first universal coupling, the universal joint shaft bar, second universal coupling, gear on worm is paid, regulating shaft places in the wallboard and with first universal coupling and links, the universal joint shaft bar connects first universal coupling and second universal coupling, second universal coupling connects worm screw, spindle nose one end of eccentric shaft places in the gear axis hole, and gear on worm is paid and driven the eccentric shaft rotation.
Above-mentioned inking roller pressure-regulating device, described gear are helical gear, and gear on worm is paid to worm and helical gear and paid.
Operation principle of the present utility model is the combining form of adopting universal coupling and gear on worm to pay, regulating shaft is housed on wallboard, regulating shaft connects universal coupling, universal coupling connects worm screw, paying the drive eccentric shaft through worm and helical gear rotates, move through connecting rod and then drive inking roller glue boom, realize the pressure adjustment of inking roller and plate cylinder.Adopt the universal coupling structure to save parts such as support plate, guide pile, compact conformation, and be that condition has been created in the appearance design of printing unit; Worm and helical gear is paid transmission and is had self-locking performance preferably, can eliminate the pressure phenomenon of walking about; Regulating shaft places between unit near and the position, the inboard measuring pressure place of wallboard, and the comparatively convenient and safety of single adjusting pressure in practical operation can be fast, correctly pressure is adjusted to desirable value, and it is convenient, reliably to regulate pressure.
(4) description of drawings
Fig. 1 is the utility model inking roller pressure-regulating device structural representation, and Fig. 2 is that the A-A of Fig. 1 is to cross-sectional schematic.
Among the figure: 1 regulating shaft, 2 first universal couplings, 3 universal joint shaft bars, 4 lobe plates, 5 plate cylinders, 6 second universal couplings, 7 bearings, 8 inking rollers, 9 inking roller glue booms, 10 worm screws (worm and helical gear is paid), 11 plate cylinder centers, 12 wallboards, 13 connecting rods, 14 eccentric shafts.
(5) specific embodiment
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2, a kind of inking roller pressure-regulating device comprises that eccentric shaft 14, connecting rod 13, inking roller glue boom 9, regulating shaft 1, first universal coupling 2, universal joint shaft bar 3, second universal coupling 6, gear on worm pay 10.Regulating shaft 1 places in the wallboard 12 and with first universal coupling 2 and links, universal joint shaft bar 3 connects first universal coupling 2 and second universal coupling 6, second universal coupling 6 connects worm screw 10, spindle nose one end of eccentric shaft 14 places in the gear axis hole, and gear on worm is paid 10 and driven eccentric shaft 14 rotations.Gear is a helical gear, and gear on worm is paid to worm and helical gear and paid 10.Eccentric shaft 14 drivening rods 13, connecting rod 13 drives inking roller glue boom 9 and moves, and realizes the pressure adjustment of inking roller 8 and plate cylinder 5.
For making the rotation that connects the back universal coupling flexible, the working face place that should make first, second shaft coupling two ends during assembling at grade.For guaranteeing the stability of pressure, worm and helical gear is paid and should be assembled into zero sideshake.
Claims (2)
1. inking roller pressure-regulating device, comprise eccentric shaft, connecting rod, inking roller glue boom, the eccentric shaft drivening rod, connecting rod drives inking roller glue boom and moves, it is characterized in that this inking roller pressure-regulating device also comprises regulating shaft, first universal coupling, the universal joint shaft bar, second universal coupling, gear on worm is paid, regulating shaft places in the wallboard and with first universal coupling and links, the universal joint shaft bar connects first universal coupling and second universal coupling, second universal coupling connects worm screw, spindle nose one end of eccentric shaft places in the gear axis hole, and gear on worm is paid and driven the eccentric shaft rotation.
