Abstract
The utility model discloses a kind of Jacquard head, including support frame, motor is installed on support frame as described above, the first eccentric wheel and the second eccentric wheel are separately installed with the rotating shaft of the motor, first eccentric wheel is griffed frame by first connecting rod and first and is connected, second eccentric wheel is griffed frame by second connecting rod and second and is connected, and relative to rotating shaft axial symmetry, described first, which griffes frame and second, griffes to be separately installed with frame and griffe for first eccentric wheel and the second eccentric wheel.So that stability when improving rotating shaft operation.
Description
Technical field
It the utility model is related to textile machine, and in particular to a kind of Jacquard head.
Background technology
The shedding mechanism of jacquard configures one group of perpendicular pin and one is equipped with the knife rest griffed.Knife rest by direct spindle drive Lai
The perpendicular pin of lifting.Main shaft turns around, and knife rest lifts once, forms a shed open.Warp thread passes through the harness eye of heald, and heald lower end plays
Weight, comprehensive effect is played back, the eyelet of harness cord through keevil is connected with hook, and hook upper end is first line.Perpendicular pin passes through head
Line and harness cord connect, griffed on knife rest equipped with some.When perpendicular pinhock is on griffing, knife rest moves upwards.Griffe just
Lift perpendicular nail therewith by seedling line, hook, harness cord, braid twine helad silk to lift, the warp thread lifting being through in harness eye.Knife rest rises same
When bottom plate decline no elevated perpendicular pin and decline therewith, the warp thread of control declines.The warp thread of lifting into shed open upper strata, decline
Warp thread forms shed open lower floor.The lifting that a head provides dynamic Control knife rest is configured with jacquard.But in the market head
Unstable vibrations are larger during operation.
Utility model content
The purpose of this utility model is to provide a kind of Jacquard head have the characteristics of stability is good.
In order to achieve the above object, the technical solution of the utility model is：A kind of Jacquard head, including support frame, institute
State and motor is installed on support frame, be separately installed with the first eccentric wheel and the second eccentric wheel in the rotating shaft of the motor, described
One eccentric wheel is griffed frame by first connecting rod and first and is connected, and second eccentric wheel griffes frame phase by second connecting rod and second
Even, relative to rotating shaft axial symmetry, described first, which griffes frame and second, griffes to divide on frame for first eccentric wheel and the second eccentric wheel
It is not provided with and griffes.
First eccentric wheel is circle, and the first connecting rod offers manhole, and the first connecting rod is sheathed on the
On one eccentric wheel, second eccentric wheel is circle, and the second connecting rod offers manhole, and the second connecting rod is sheathed on
On second eccentric wheel.
The beneficial effects of the utility model are：First eccentric wheel and the second eccentric wheel relative to rotating shaft axial symmetry so that
Improve stability during rotating shaft operation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment 1
As shown in figure 1, a kind of Jacquard head, including support frame 1, motor, the motor are installed on support frame as described above 1
Rotating shaft 2 on be separately installed with the first eccentric wheel 3 and the second eccentric wheel 4, first eccentric wheel 3 passes through first connecting rod 5 and
One griffe frame 6 be connected, second eccentric wheel 4 is griffed frame 8 with second by second connecting rod 7 and is connected, first eccentric wheel 3 and
Relative to the axial symmetry of rotating shaft 2, described first griffes frame 6 and second griffes to be separately installed with frame 8 and griffes 9 second eccentric wheel 4, from
And make raising rotating shaft run when stability.
First eccentric wheel 3 is circle, and the first connecting rod 5 offers manhole, and the first connecting rod 5 is sheathed on
On first eccentric wheel 3, second eccentric wheel 4 is circle, and the second connecting rod 7 offers manhole, the second connecting rod 7
It is sheathed on the second eccentric wheel 4.Centrifugal force is to first connecting rod junction when reducing the first eccentric wheel and the operation of the second eccentric wheel
Influence.
