Description
Technical field
Printing equipment is the utility model is related to, particularly a kind of roller is grited one's teeth axle controls device and offset press.
Background technology
Cylinder in offset printing press departs from pine by gritting one's teeth to compress to clamp paper and grit one's teeth with bite-block in printing process with bite-block
Open and the mode that paper is sent out is connected sheets.In this process, the mode master for the opening and closing operation that roller is grited one's teeth is realized
Will be by the way of single cam and stage clip combine.When high speed printing, because stage clip does not stop to be impacted, open on tooth spherical pendulum bar
The early right side in left side is slightly when opening tooth ball and easily produce small bounce and vibration in cam face, while also easily producing opening and closing
The phenomenon of the early left side in late or right side a little later, so as to have impact on printing quality, the opening and closing cycle for making to grit one's teeth changes, nothing
The accurate gripper of method, therefore be not suitable for high speed printing.
Utility model content
The tooth ball of opening opened during in order to solve high speed printing on tooth spherical pendulum bar produces small bounce and vibration in cam face
Problem asynchronous with the real time of the opening and closing of gritting one's teeth for axle left and right sides of gritting one's teeth, grited one's teeth axle the utility model proposes a kind of roller
Control device and offset press.
The utility model is for overcome the deficiencies in the prior art, there is provided a kind of roller is grited one's teeth axle controls device, including is stung
Tooth axle, left conjugate cam drive component and right conjugate cam drive component, the left conjugate cam drive component and right conjugation are convex
Wheel drive component is separately mounted to axle both ends of gritting one's teeth, synchronous to drive axle swing of gritting one's teeth.
By respectively setting a conjugate cam drive component at the both ends for axle of gritting one's teeth, when offset press works, both sides are simultaneously right
Axle of gritting one's teeth applies driving, and the stress for the axle that makes to grit one's teeth is more balanced, avoids and concentrates axle torsional deflection of gritting one's teeth caused by stress.
In the embodiment of the utility model one, the left conjugate cam drive component opens tooth ball including a left side, tooth spherical pendulum is opened on a left side
Bar and left conjugate cam；The right conjugate cam drive component opens tooth ball including the right side, the right side is kicked off swing rod and right conjugate cam；
The left conjugate cam includes left main cam and left secondary cam, is arranged on side by side near axle left end of gritting one's teeth；It is described to open
Tooth ball including left master opens tooth ball and left secondary opens tooth ball, described to open that tooth spherical pendulum bar drives tooth spherical pendulum bar including left master and left secondary opens tooth spherical pendulum
Tooth ball is opened and axle left end of gritting one's teeth is connected in bar, the both ends that left master drives tooth spherical pendulum bar with left master respectively, makes that left master opens tooth ball and left master is convex
Wheel fitting；Tooth ball is opened and axle left end of gritting one's teeth is connected in the both ends that left secondary drives tooth spherical pendulum bar with left secondary respectively, left secondary is opened tooth ball and a left side
Auxiliary cam is bonded；Left master drive tooth spherical pendulum bar and left secondary drive tooth spherical pendulum bar between form left conjugate angle；
The right conjugate cam includes right main cam and right auxiliary cam, is arranged on side by side near axle right-hand member of gritting one's teeth；It is described to open
Tooth ball including right master opens tooth ball and right pair opens tooth ball, described to open that tooth spherical pendulum bar drives tooth spherical pendulum bar including right master and right pair opens tooth spherical pendulum
Tooth ball is opened and axle right-hand member of gritting one's teeth is connected in bar, the both ends that right master drives tooth spherical pendulum bar with right master respectively, makes that right master opens tooth ball and right master is convex
Wheel fitting；Tooth ball is opened and axle right-hand member of gritting one's teeth is connected in the both ends that right pair drives tooth spherical pendulum bar with right pair respectively, right pair is opened tooth ball and the right side
Auxiliary cam is bonded；Right master drive tooth spherical pendulum bar and right pair drive tooth spherical pendulum bar between form right conjugate angle.
The opening and closing grited one's teeth are realized using conjugate cam, eliminate stage clip structure, therefore also will not be because in running at high speed
Small bounce and vibration are produced in cam face to be struck so as to out tooth ball, ensure that the operation stability of equipment.
The size of the left conjugate angle be by the periphery surface curve of left conjugate cam, left master opens tooth spherical pendulum pole length, left secondary opens tooth
Spherical pendulum pole length determines；Right conjugate angle is similarly.
In the embodiment of the utility model one, left conjugate cam is consistent with right conjugate cam structure, and left conjugate angle is equal to
Right conjugate angle.
As long as ensureing that left conjugate cam is consistent with the service cycle of right conjugate cam, according to the size of assembly space, transmission
The riding position of structure, its profile can be different, but lead to component module using the structure of size shape all same, one
With change, in part because senile abrasion occurs in long-term use when needing to change, without preparing substantial amounts of acknowledgment copy, one group of conjugation is convex
The spare part of wheel can meet the replacement of the conjugate cam of both sides；The two cam is consistent with Kai Ya spherical pendulum pole lengths, each position by
