Description
Technical field
A kind of eccentric rotary upper swing type Web transfer apparatus for printing machine is the utility model is related to, belongs to printing machine equipment skill
Art field.
Background technology
From the aspects of typography flow, the technological process performed by printing machine Web transfer apparatus is to ensure printing product quality
Compare the key link;For printing machine structure composition itself, Web transfer apparatus also belongs to the core of printing machine with imprinting apparatus
Center device.
Big extension spring lower end is hung on fixed pin, then spring in the course of the work in addition to original pre-stretching, grow by stretching
Degree is constantly changing, and when resisting, tooth mechanism power performance is unfavorable.Simultaneously because spring frequent deformation, too early beyond fatigue strength
Fracture.
The stationarity and transfer precision of the transfer gripper motion of traditional Web transfer apparatus are low, transfer gripper complicated movement, design,
Manufacture, the difficulty of adjustment are very big.
The content of the invention
The purpose of this utility model is to provide a kind of eccentric rotary upper swing type Web transfer apparatus for printing machine, it is not necessary to etc.
Roller neutral gear and return in advance, can both reduce roller neutral gear and diameter of cylinder, can improve again transfer gripper motion stationarity and
Transfer precision.
The utility model to achieve these goals, adopts the following technical scheme that：
A kind of eccentric rotary upper swing type Web transfer apparatus for printing machine, it includes transfer gripper swinging axle, roller, the first pendulum
Bar, the second swing rod, connecting rod, big extension spring, chain, sprocket wheel, transfer gripper travelling gear, positioning screw, positioning centering block, cam；
Transfer gripper swinging axle is in the capacity eccentric bearing in both walls plate hole, respectively equipped with one and pressure on each capacity eccentric bearing
The print transfer gripper travelling gear that roller rotate gear is meshed, reference diameter is equal；
Also include a cam for being arranged on impression cylinder spindle nose；
Second swing rod and transfer gripper swinging axle are affixed, the other end connection connecting rod of the second swing rod, the other end connection of connecting rod
First swing rod；
The side edge of roller and cam is touched.
Further, sprocket wheel and chain are provided with transfer gripper travelling gear.
Further, big extension spring lower end is hung on fixed pin or active pin shaft, and upper end is fixed on transfer gripper swinging axle
On.
Further, the second swing rod lower end is provided with positioning centering block, it is fixed by positioning screw.
The beneficial effects of the utility model：
The utility model improves transfer gripper oscillation center in backhaul, movement locus is as a result of rotating eccentricity
" water droplet " shape closed curve, touch less than drum functions surface during return, can need not so wait roller neutral gear and return in advance, both may be used
To reduce roller neutral gear and diameter of cylinder, the stationarity and transfer precision of transfer gripper motion can be improved again.
In the utility model, extension spring is not to hang on fixed active pin shaft, but is hung on a movable bearing pin.
The bearing pin is driven by a set of tracking cam and swing-bar mechanism, extension spring is remained certain drawing in the whole motion process of transfer gripper
Elongation, produce certain pulling force.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings：
A kind of eccentric rotary upper swing type Web transfer apparatus for printing machine, it includes transfer gripper swinging axle 1, roller 2, first
Swing rod 3, the second swing rod 5, connecting rod 4, big extension spring 6, chain 7, sprocket wheel 8, transfer gripper travelling gear 9, positioning screw 10, positioning centering block
11st, cam 12；
In capacity eccentric bearing of the transfer gripper swinging axle 1 in the both walls plate hole, on each capacity eccentric bearing respectively equipped with one with
The transfer gripper travelling gear 9 that impression cylinder rotate gear is meshed, reference diameter is equal；
Also include a cam 12 for being arranged on impression cylinder spindle nose；
Second swing rod 5 and transfer gripper swinging axle 1 are affixed, the other end connection connecting rod 4 of the second swing rod 5, the other end of connecting rod 4
Connect the first swing rod 3；
The side edge of roller 2 and cam 12 is touched.
Sprocket wheel 8 and chain 7 are provided with transfer gripper travelling gear 9.
The big lower end of extension spring 6 is hung on fixed pin or active pin shaft, and upper end is fixed on transfer gripper swinging axle 1.
Positioning centering block 11 is provided with the lower end of the second swing rod 5, it is fixed by positioning screw 10.
In capacity eccentric bearing of the transfer gripper swinging axle 1 in the both walls plate hole, on each capacity eccentric bearing respectively equipped with one with
The transfer gripper transmission gear 9 that impression cylinder transmission gear is meshed, reference diameter is equal, therefore capacity eccentric bearing drives transfer gripper
Swinging axle 1 is rotated about center and rotated with the velocity reversal synchronous with impression cylinder, at the same time, installed in impression cylinder spindle nose
Cam 12 rotate, by roller 2, the first swing rod 3, connecting rod 4, drive and make to swing fortune with the second swing rod 5 of transfer gripper axle consolidation
It is dynamic, so that the transfer gripper being fixedly mounted on transfer gripper axle makees reciprocally swinging sheets relative to axle.
Therefore, the motion of transfer gripper is its oscillation center（Transfer gripper axle）, the at the uniform velocity rotation fortune made around eccentric bushing center
It is dynamic（Lead fast motion）With the oscillating motion relative to transfer gripper oscillation center driven by cam link mechanism（Relative motion）'s
Resultant motion.As a result of rotating eccentricity, improve transfer gripper oscillation center in backhaul, movement locus seals for " water droplet " shape
Closed curve, touch less than drum functions surface during return, can need not so wait roller neutral gear and return in advance, can both reduce roller
Neutral gear and diameter of cylinder, the stationarity and transfer precision of transfer gripper motion can be improved again.But due to adding the rotation fortune of bias
It is dynamic, make transfer gripper complicated movement, add mechanism design, manufacture, the difficulty of adjustment.
Above-mentioned transfer dental structure is inertia for overcoming and balancing transfer gripper swing process, and it makes linkage
Roller 2 is close to transfer gripper cam all the time, to keep force-closed and strict movement relation, impact is prevented, due to transfer gripper
Swinging axle 1 itself is made oscillating motion by cam, linkage control, is fixed on transfer gripper axle around eccentric central rotation, transfer gripper
On the extension spring active pin shaft at both ends, its position constantly changes in motion process.
In the utility model, extension spring is not to hang on fixed active pin shaft, but is hung on a movable bearing pin.
The bearing pin is driven by a set of tracking cam and swing-bar mechanism, extension spring is remained certain drawing in the whole motion process of transfer gripper
Elongation, produce certain pulling force.
