Description
Technical field
The invention belongs to field of textiles, and in particular to a kind of passive type unwinding the warp tension-adjusting gear, be interrupted for weaving
The tension force and warp let-off quantity regulating device that formula increases the special cloth cover effect fabrics such as the seersucker of warp run-in, Wrinkle fabric and installed additional.
Background technology
Warp-wise part or full width are weaved on loom to be had bubble, wrinkle effect, needs non-momentary change warp let-off tension force, and increase is sent
Warp let-off mode through amount, prior art are using mechanical cam ratchet, ratchet warp let-off mode or electricity that either crank controls
Sub- warp let-off servomotor is combined with tensile strain piece sensor, by presetting warp tension size, by steeping axle and the earth's axis
The mode of warp run-in difference realizes above-mentioned cloth cover effect.Mechanism is complicated, and weaving cost is high, maintenance is big, easily produces failure.
The content of the invention
Goal of the invention：In order to solve the deficiencies in the prior art, the invention provides a kind of passive type unwinding the warp tension force tune
Regulating device.
Technical scheme：Passive type unwinding the warp tension-adjusting gear, including unwinding beam of a loom, warp thread, retaining retaining hook, double-rod
Tension rail, gyroaxis, heald frame, spring, takers-in, beam of a loom, tension rail, pass through, weft yarn, shed open, fabric and tooth form beam disc for weaving；
The warp thread is drawn by unwinding beam of a loom and bypass double-rod tension rail, is divided into upper and lower two layers through heald frame, with weft yarns into
After fabric, drawn through takers-in；
By controlling warp tension, double-rod tension rail can be set with retaining retaining hook thereon and opened with wraparound shaft swing
Power bar, tension rail one end pocketed springs, the spring other end are fixed on loom side；
Under the pulling force effect of spring, retaining retaining hook is turned round clockwise, is tightly stuck in the tooth form beam disc for weaving of warp beam right-hand member
In tooth, engage, limitation unwinds the beam of a loom turning anticlockwise under the unwinding tension effect of warp thread counterclockwise, so as to send out
Warp thread, and now takers-in is turning round clockwise, there is the trend for deflecting from fabric, thus the unwinding beam of a loom of warp thread is wrapped with batching
Warp tension between roller can be built up, and the warp tension of increase is applied on double-rod tension rail, make it together with being set with thereon
Tension rail have the trend around gyroaxis turning anticlockwise, when tension buildup increase to a certain extent, drive be set with thereon only
Surrender tenaculum overcomes spring force turning anticlockwise together, so that retaining retaining hook is disengaged from shape with tooth form beam disc for weaving
State, unwinding resistance release, and so as to steep through unwinding beam of a loom in the presence of warp tension, turning anticlockwise, send out warp thread；
Because tension force reduces after the warp let-off, spring pulls tension rail, is returned clockwise again around gyroaxis together with retaining retaining hook
Turn, active force, which is more than, makes the warp tension of the two turning anticlockwise, retaining retaining hook thus be pressed in again on tooth form beam disc for weaving,
Its revolution is limited, and so on.
As optimization：The passive type unwinding the warp tension-adjusting gear is that warp thread is not when utilizing retaining retaining hook retaining
Send out, this stage because takers-in batch effect and increased warp tension is acted on double-rod tension rail, be allowed to counterclockwise return
When turning, retaining retaining hook disengages the passive foaming warp yarn supplying mode to be formed with tooth form beam disc for weaving.
As optimization：The size of tension force can be by the elastic force of spring, or adjusts it in the position of tension rail with adjusting force
The mode of arm is adjusted.
Beneficial effect：The present invention is that warp thread is not sent out, and this stage batches because takers-in when utilizing retaining retaining hook retaining
Effect and increased warp tension is acted on double-rod tension rail, when being allowed to turning anticlockwise, retaining retaining hook and tooth form beam of a loom
Disc disengages the passive foaming warp yarn supplying mode to be formed.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
With reference to specific embodiment, the invention will be further described.
Embodiment
As shown in figure 1, a kind of passive type unwinding the warp tension-adjusting gear, including unwinding beam of a loom 1, warp thread 2, retaining are kept
Hook 3, double-rod tension rail 4, gyroaxis 5, heald frame 6, spring 7, takers-in 8, beam of a loom 9, tension rail 10, through 11, weft yarn 12, shed open
13rd, fabric 14 and tooth form beam disc for weaving 15.Warp thread 2 is drawn by unwinding beam of a loom 1, around double-rod tension rail 4, is divided into through heald frame 6
It is lower two layers, after being woven into fabric 14 with weft yarn 12, drawn through takers-in 8.The present apparatus passively adjusts unwinding beam of a loom 1 using discontinuous
Instantaneous warp let-off tension force, so as to increase warp run-in so that warp thread is into wavy, with continuously being unwind on the beam of a loom 9 of the continuous warp let-off
Warp thread is divided into two layers up and down through heald frame by a certain percentage and with after, forms shed open 13, fabric 14 is interweaved into weft yarn 12,
Drawn through takers-in 8.
By controlling warp tension, double-rod tension rail 4 can be swung around gyroaxis 5, be set with the He of retaining retaining hook 3 thereon
Tension rail 10, one end pocketed springs 7 of tension rail 10, the other end of spring 7 is fixed on loom side, in the pulling force effect of spring 7
Under, retaining retaining hook 3 is turned round clockwise, is tightly stuck in the tooth of tooth form beam disc for weaving 15 of warp beam right-hand member, is engaged, limitation unwinding
The turning anticlockwise under the unwinding tension effect of warp thread 2 counterclockwise of beam of a loom 1, so as to can not send out warp thread, and now takers-in 8 exists
Revolution clockwise, there are the trend for deflecting from fabric, thus the warp tension being wrapped between the unwinding beam of a loom 1 of warp thread and takers-in 8
It can build up.The warp tension of increase is applied to (shown in dotted line) on double-rod tension rail 4, makes it together with the tension force being set with thereon
Bar 10 has the trend around the turning anticlockwise of gyroaxis 5, to a certain extent, drives the retaining being set with thereon to protect when tension buildup increases
Tenaculum 3 overcomes the elastic force turning anticlockwise of spring 7 together, so that retaining retaining hook 3 is disengaged from tooth form beam disc for weaving 15
State, unwinding resistance release, and so as to steep through unwinding beam of a loom in the presence of warp tension, turning anticlockwise, send out warp thread.The warp let-off
Afterwards because tension force reduces, spring 7 pulls tension rail, together with retaining retaining hook 3 around the revolution clockwise again of gyroaxis 5, active force
More than the warp tension for making the two turning anticlockwise, retaining retaining hook 3 is thus pressed on tooth form beam disc for weaving 15 again.Limit it
Revolution, and so on.
The present apparatus is that warp thread is not sent out when utilizing retaining 3 retaining of retaining hook, this stage because takers-in 8 batch effect and
Increased warp tension is acted on double-rod tension rail 4, when being allowed to turning anticlockwise, retaining retaining hook 3 and tooth form beam disc for weaving
15 disengage the passive foaming warp yarn supplying mode to be formed.
The size of tension force can be by the elastic force of spring 7, or adjusts it in the position of tension rail in a manner of adjusting the arm of force
To adjust.
The present invention is not limited to above-mentioned preferred forms, and anyone can show that other are various under the enlightenment of the present invention
The product of form, however, make any change in its shape or structure, it is every that there is skill identical or similar to the present application
Art scheme, is within the scope of the present invention.
