The utility model relates to printing machinery, relates in particular to the jockey of ink fountain and ink foundation roller in the offset press.
(2) background technology
The China ink amount size adjustment mechanism of printing machinery generally is to realize by the gap of adjusting between the ink fountain blade on ink foundation roller and the ink fountain.For general rotary press, ink fountain can directly be fixed on the spacer pedestal that is connected with the both sides wallboard with pin, and the ink fountain handle can unclamp ink fountain and clean, and ink fountain leans against on the joint surface when closing, and is in normal operating position.Ink fountain and ink foundation roller are positioned at respectively on the wallboard of both sides, guarantee that by the machined precision position between ink fountain and the ink foundation roller concerns.Because the dimension chain relatively is long and also have the action of folding, thereby be in when closing the operating position when ink fountain, the constancy of the distance between the ink fountain edge of a knife and the ink foundation roller, and the tolerance control ratio of the depth of parallelism between the two is difficult.For sheet-fed offset press, China ink amount degree of regulation requires height, and structure precision requires also high, and the structure between existing ink fountain and the ink foundation roller is not suitable for requiring the accurately occasion of adjusting of China ink amount.
(3) summary of the invention
The structure that the utility model has overcome between existing ink fountain and the ink foundation roller is not suitable for requiring the accurately occasion of adjusting of China ink amount, and a kind of ink fountain and ink foundation roller firm joint device are provided.This ink fountain adopts ink fountain directly to be connected with ink foundation roller with the ink foundation roller firm joint device, thereby improves the relative positional accuracy of the two, improves the control accuracy of China ink amount, and easy to adjust, flexible operation is installed.
The utility model is achieved in that a kind of ink fountain and ink foundation roller firm joint device, comprise ink fountain, ink foundation roller, supporting pin, ink fountain comprises the ink fountain side plate of both sides, supporting pin places ink fountain side plate lower end, it is characterized in that ink fountain and ink foundation roller firm joint device also comprise steel wire, back-up ring, bearing, screw, spring, at the ink foundation roller two ends bearing is housed, bearing outer ring is equipped with back-up ring, and the back-up ring periphery radially has a circumferential recess along ink foundation roller; Steel wire hoop is enclosed within the back-up ring circumferential recess at ink foundation roller two ends, and steel wire one end is connected on the short pin of ink fountain side plate one side, and the ink fountain side plate has the through hole that diameter differs, through hole is built-in with the piece plate, through hole is equipped with screw outward, and short pin is fixed in the piece plate, and the piece plate is held by the screw that is sleeved on the spring; The steel wire other end is connected on the swivel pin on the operating grip of ink fountain side plate opposite side, and operating grip is that minor axis is connected with the ink fountain side plate.
Above-mentioned ink fountain and ink foundation roller firm joint device, the described supporting pin that is positioned at ink fountain side plate lower end is set in the rubber shaft bearing that is fixed on the wallboard support.
Above-mentioned ink fountain and ink foundation roller firm joint device, it is disk spring that newspaper is stated spring.
Operation principle of the present utility model is to adopt ink fountain directly to be connected with ink foundation roller, be enclosed within on the back-up ring on the ink foundation roller by steel wire hoop ink fountain is connected with ink foundation roller, and the steel wire strainer is housed on the ink fountain side plate, dimension chain between ink fountain and ink foundation roller is shortened, thus the relative positional accuracy between raising ink fountain and ink foundation roller; Under the identical condition of machining accuracy, assembly precision is higher, and the control accuracy of China ink amount has improved; And easy to adjust, flexible operation is installed.
(4) description of drawings
Fig. 1 is the utility model ink fountain and ink foundation roller firm joint device structural representation, and Fig. 2 is the A-A cross-sectional schematic of Fig. 1, and Fig. 3 is existing ink fountain and ink foundation roller structural representation.
Among the figure: 1 ink fountain, 2 wallboards, 3 ink foundation rollers, 4 steel wires, 5 back-up rings, 6 bearings, 7 ink fountain side plates, 8 supporting pins, 9 rubber shaft bearings, 10 swivel pins, 11 operating grips, 12 screws, 13 disk springs (spring), 14 short pins, 15 blocks of plates, 16 through holes, 17 minor axises, 18 supports, 19 ink fountain blades, 20 pedestals, 21 handles, 22 gaps, 23 joint surfaces.
(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 ink fountain and ink foundation roller firm joint device comprise ink fountain 1, ink foundation roller 3, supporting pin 8, steel wire 4, back-up ring 5, bearing 6, screw 12, spring 13.Ink fountain 1 comprises the ink fountain side plate 7 of both sides.At ink foundation roller 3 two ends bearing 6 is housed, back-up ring 5 is equipped with in bearing 6 outer rings, and back-up ring 5 peripheries radially have a circumferential recess along ink foundation roller 3; Steel wire 4 hoops are enclosed within back-up ring 5 circumferential recess at ink foundation roller 3 two ends, steel wire 4 one ends are connected on the short pin 14 of ink fountain side plate 7 one sides, ink fountain side plate 7 has the through hole 16 that diameter differs, through hole 16 is built-in with piece plate 15, through hole is equipped with screw 12 outward, short pin 14 is fixed in piece plate 15, and piece plate 15 is held by the screw 12 that is sleeved on the spring 13, and spring 13 is a disk spring; Steel wire 4 other ends are connected on the swivel pin 10 on the operating grip 11 of ink fountain side plate 7 opposite sides, and operating grip 11 and ink fountain side plate 7 are connected for minor axis 17.Like this ink fountain 1 directly with ink foundation roller 3 location, rotation when ink foundation roller 3 work, but the back-up ring 5 on the ink foundation roller 3 do not rotate owing to be contained on the bearing 6, is convenient to the closing of ink fountain side plate 7 and back-up ring 5.Steel wire 4 is during by disk spring 13 tensionings, and ink fountain side plate 7 is close to the back-up ring 5 on the ink foundation roller 3, and ink fountain 1 is directly determined the position relation with ink foundation roller 3; If slightly circular runout of ink foundation roller 3, ink fountain 1 floats with ink foundation roller 3, can continue to keep the clearance constant of the two.
