Description
Technical field
The invention belongs to field of textile machinery, a kind of High speed cam shedding motion is related generally to.
Background technology
Present shedding motion is typically more traditional, and structure is more simple and crude, and stability is not good enough, and part is easily damaged, stops
Comprehensive flat effect can not be properly arrived at when only working.
The content of the invention
It is excessively smooth and can reach during a kind of steady when the technical problems to be solved by the invention are to provide operation, power cut-off
To the High speed cam shedding motion of comprehensive flat effect.
The present invention is achieved through the following technical solutions：
A kind of High speed cam shedding motion, comprising base, cam set and heald lifting arm group, the cam set and heald lifting arm group are respectively provided with
On base, the cam set is made up of the cam of some Heterogeneous Permutations, and the heald lifting arm group with cam number identical by carrying
Cam in comprehensive arm composition, the cam set is corresponded with the heald lifting arm in heald lifting arm group to be set, and the heald lifting arm is included and carried
Comprehensive arm top and heald lifting arm bottom, the heald lifting arm by being fixed on two rollers and cam contact at heald lifting arm bottom two ends,
The top of the heald lifting arm is used for driving the connecting rod of the adjustable length of integrated box movement to be connected, and the cam set is by camshaft
Drive and rotate, the heald lifting arm group is arranged on shedding arm axle, and the shedding arm axle two ends are equipped with eccentric wheel, one
The outside of eccentric wheel, is also associated with putting down comprehensive spanner, described to put down the separation that comprehensive spanner is used to control cam and heald lifting arm, the shedding
A spacing flat heald rod is additionally provided with below the bottom of arm and the other edge of cam contact.
Preferably, the distance between the heald lifting arm and spacing flat heald rod are 40-60mm.
More preferably, the distance between the heald lifting arm and spacing flat heald rod are 50mm.
Preferably, the High speed cam shedding motion also includes shell.
Preferably, the quantity of the cam set cam is up to 8.
Preferably, large bevel gear is fixedly installed on the camshaft, the umbellule that large bevel gear is connected with by motor shaft
Gear coordinates to be rotated with realizing that camshaft is driven by motor.
Preferably, the camshaft is provided with cam orientation disk, baseline rod, the dry number of control benchmark are provided with positioning disk
Equal to Weaving Cycle number, the cam only with phase suspension period can be just installed on same axis, the camshaft
On be additionally provided with camshaft spacer and cam shaft bush.
The High speed cam shedding motion operation principle：
During normal operation, heald lifting arm is contacted with cam by roller, because cam is shifted to install, so now per adjacent two
The heald lifting arm of piece is staggered the roller top of setting into not concordant two panels, therefore heald lifting arm is divided on not concordant two parts do not stop
It is lower staggeredly to swing, to drive integrated box movement；
When needing machine to shut down, that is, being rotated up flat comprehensive spanner makes cam be separated with heald lifting arm, specifically：When to
When comprehensive spanner is put down in upper rotation, eccentric wheel, which is driven, to be rotated up, and shedding arm axle wants upward back rotation, because heald frame passes through connecting rod
Give heald lifting arm one active force forward, heald lifting arm is first contacted with spacing flat heald rod, continue the comprehensive spanner of rotary flat with rotating eccentricity
The distance of roller and cam on wheel, heald lifting arm is more and more remote, and last embodiment is：Roller is kept completely separate with cam, heald lifting arm
Also it is all concordant, reach comprehensive flat effect.
Beneficial effects of the present invention：The High speed cam shedding motion compact overall structure of the present invention, because eccentric wheel is skilful
Wonderful to set, stability is good, easy to control, it is easy to reach flat comprehensive effect, and manufacturing cost is low, is worthy to be popularized.
