Abstract

To provide a warp knitting machine of kind mentioned at the beginning, having an especially preferable structure in practical application, and capable of relatively changing the basic position of a guide needle to a knitting needle. This warp knitting machine has at least one guide bar 4 supported on a reciprocatively swingable guide lever 9. In order to relatively change the basic position of the guide needle 3 to a knitting needle 2, the swinging movement line of the guide lever can relatively and integrally be changed to a frame 21. The guide lever 9 is provided with good torsional rigidity, is linked to a common swinging shaft 10, and supports at least one guide bar 4 through axial guides 7, 8. The swinging shaft 10 is supported in the frame 21 through a rotatingly controllable eccentric bushing 14. Thereby, the practically preferable structure wherein the basic position of a guide needle 3 can relatively be changed to the knitting needle 2 is obtained.

Description

Warp knitting machine

Technical field

The present invention relates to a kind of warp knitting machine that has a sley bar at least.This sley bar is that origin is returned the guide lever supporting that can swing, and the swinging axle of guide lever can jointly be adjusted with respect to frame, so that the home position of sley point is changed with respect to knitting needle.

Background technology

A kind of like this warp knitting machine is open by patent DE-PS 959 939, promptly has the warp knitting machine of unique sley bar.Sley point both perpendicular to, also be can swing round the bearing of forming by ball journal lining and spherical journal along needle-bar.Each is supported these bearings by a spacing bar, and this spacing bar then is bearing on the adjustment axle that places in the frame.This adjustment axle is adjusted lever by means of one can swing about 45 °, and sley point is adjusted on its height and position from a position.

Can find a kind of warp knitting machine by DD-PS 44092, its sley bar is placed on the connecting rod of a hinged tetragonal part under connecting in the middle of the axial guiding device, and one of them hingedly can move with respect to frame by means of an eccentric wheel herein.Just can make sley point bring one into to help on the position that warp thread penetrates by rotating 180 ° of this eccentric wheels.

Summary of the invention

Task of the present invention just is, the warp knitting machine of the described type of this explanation beginning can in the particularly advantageous structure, be realized the variation of sley point home position with respect to knitting needle at one for practice.

Solve by following approach by this task of the present invention, guide lever is connected with a common swinging axle antitorquely, and guide lever supports one or more sley bars, wherein between sley bar and guide lever, be provided with an axial guiding device, swinging axle is bearing in the frame, wherein is provided with the eccentric bushing of rotatable adjustment between swinging axle and frame.

Can realize the adjustment of desired sley point with the common swinging axle of all sley bars by one for this structure.Can abandon using the spherical journal bearing, because the axial dipole field of sley bar can be accepted by axial guiding device.By rotating the eccentric adjusting sleeve that this is positioned at place, convenient approximated position simply, make sley point, for example on the knocking over position of knitting needle, change its home position.

Eccentric adjusting sleeve can be rotated on swinging axle also can be clamped.This rotation and clamping structurally all are to realize easily.

Also recommendable is with the eccentric adjusting sleeve fluting, and is surrounded by the clamping ring of a fluting.Because clamping ring has surrounded excentric sleeve, thereby clamping ring is just close easily.

An adjustment ring that has mark is connected with excentric sleeve antitorquely.Thereby can read each rotary angle position, and can repeatedly set up.

A kind of method of special simplification is clamping ring to be constituted adjust ring.

For a kind of preferred form of implementation, can realize wobble drive by a connecting hole by means of a push rod at least one sley bar opposite one end of guide lever.The effect of this connecting hole is exactly the point of rotation as guide lever when adjusting eccentric bushing, but its position is slightly changed.This drives for a push rod and allows.

Description of drawings

Below the present invention is described in detail according to a preferred embodiment shown in the drawings.This paper is attached two figure altogether, wherein:

Fig. 1. a pith of the warp knitting machine of the present invention that main body is represented;

Fig. 2. by the cross section of this part of warp knitting machine.

The specific embodiment

See from the working range 1 of warp knitting machine and just to have expressed knitting needle 2 and sley point 3.Sley point is an eye needle guide, and by

sley bar

4,5 and 6 supportings, the latter links to each other with guide lever 9, wherein

sley bar

4,5 and 6 and guide lever 9 between axial guiding

device

7 and 8 are set.These guide levers are sandwiched on the swinging axle 10.Realize wobble drive by a push rod, this push rod is stretched in a support of not expressing, and it for example just encloses the eccentric wheel that encases by one by bearer ring and drives in this support.Push rod acts on the hinged a chain of hole 12, and this hole is arranged in the end 13 of guide lever 9, and this end is in the opposite of sley bar 4 to 6.

For this structure, sley point 3 has been realized an oscillating motion, and this moment, it moved to the preceding lapping position of pin with the underlap position, and returned again.In order to change the home position that is occupied when sley point has reached the knocking over position in working cycles, stipulate following measure:

At swinging axle 10 upper supports an eccentric bushing 14 with a fluting 15 is arranged.This eccentric bushing 14 is surrounded by a clamping ring 16 on the part of its axial length, and this ring has a fluting 17 and pinching screw 18.Clamping ring is connected with excentric sleeve 14 antitorquely in addition, and a mark with the angle scale form is arranged, and the pointer on this scale and the machine support 21 concurs.The not clamped ring 16 of excentric sleeve 14 encloses 22 li of the deadlights that the part that encases then is placed on machine support 21 rotationally.

In order to give sley point 3 one new positions, make warp knitting machine enter its knocking over position.Clamping ring 16 unclamps and rotates one and new pass through the position that mark 19 can be read then.This moment, swinging axle 10 correspondingly moved.Pinching screw 7 is tightened again then.So just excentric sleeve 14 is fixed on the swinging axle 10.Then, warp knitting machine just is in the position work of new setting by sley point 3.
