Abstract
The utility model provides a broken yarn tension force retaining device comprising a tension force retaining ring on a yarn transmission track. The tension force retaining ring comprises external fixed rings and internal fixed rings co-axially arranged in the external fixed rings, wherein the inner side of each external fixed ring is provided with a kinetic energy slip ring driven to rotate via a driving device; each internal fixed ring is co-axially provided with an annular fan capable of sliding on the internal fixed ring; the external side of a large annular frame is equipped with a clutch ring component with a variable diameter; and clutch ring components are in friction cooperation with the kinetic energy slip ring on the inner side of each external fixed ring. When a yarn is broken, each clutch ring component is engaged with the kinetic energy slip rings, so the annular fan is driven to form air currents; and the yarn is blown by the air currents to form tension force, so the yarn is prevented from flying around.
Description
Affiliated technical field
The utility model relates to loom auxiliary equipment field, especially, is a kind of tension force holding device for loom broken yarn.
Background technology
Loom is all provided with Warp stop motions, and the object of this device is to survey cracked ends, sends stop sign.Their type: photo-electric type (far infrared detection), stop over posture, minute comb is rotary.Adopt stop over postures at present, its operation principle: stop over frame is contained between the back rest and heald frame, has several row stop over bars on it more.Stop over bar is that inside and outside two kinds of conductors are separated and form the conjunction opening circuit by thick plastic film, and many warp stop sheets are enclosed within on stop over bar, and each root warp thread is all alone through a slice warp stop sheet.During loom running, warp tension, by warp stop sheet pull-up, makes it not contact with stop over bar inner wire, and circuit is off-state.When cracked ends, warp stop sheet correspondingly falls by deadweight, contacts with inside and outside two conductors of stop over bar simultaneously, and circuit is connected, and sends stopping signal.
Traditional broken yarn monitoring device all carries out loom shut-down operation after yarn breakage again, therefore loom has certain delay at a moment of yarn breakage and carries out shut-down operation again, and yarn loses tension force in this course, cause yarn disorderly to fly, this just easily causes loom that improper accident occurs.
Utility model content
In order to address the above problem, the purpose of this utility model is to provide a kind of broken yarn tension force holding device, and this broken yarn tension force holding device can keep the tension force of yarn after yarn breakage.
The utility model solves the technical scheme that its technical problem adopts:
This broken yarn tension force holding device comprises the tension force retaining ring being arranged in yarn transmission locus, described tension force retaining ring comprises outer fixed ring and is coaxially arranged on the interior fixed ring in outer fixed ring, described outer fixed ring inner side is provided with the kinetic energy slip ring that drive unit drives rotation, in described interior fixed ring, be coaxially arranged with the annular fan that can slide in described interior fixed ring, described annular fan by large ring frame and little ring frame fixedly flabellum form, the arranged outside of described large ring frame have with described outer fixed ring inside the clutch ring element of variable-diameter of kinetic energy slip ring frictional fit, described clutch ring element is the clutch with described kinetic energy slip ring by control module control.
As preferably, described tension force retaining ring is arranged on the middle part of yarn transmission locus.
As preferably, in described interior fixed ring, slide and be provided with two annular fans that air blast direction is different.
As preferably, described clutch ring element adopts annular air-pocket that can inflation/deflation to realize clutch action.
The utility model has the advantage of:
Described control module is controlled described clutch ring element and the interlock of described kinetic energy slip ring when yarn breakage, makes the annular fan can be driven, the air-flow of the fan-shaped one-tenth of described annular, and air-flow brushes yarn and forms tension force, prevents that yarn from disorderly flying.
Accompanying drawing explanation
Fig. 1 is the structural representation of facing of this broken yarn tension force holding device.
Fig. 2 is the structural representation of facing of this broken yarn tension force holding device tension force retaining ring.
Fig. 3 is the side-looking structural representation of this broken yarn tension force holding device tension force retaining ring.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated:
In the present embodiment, consult Fig. 1, Fig. 2 and Fig. 3, this broken yarn tension force holding device comprises the tension force retaining ring 100 being arranged in yarn 10 transmission locus, yarn 10 transmission locus are between two pairs of deflector rolls are to 200, described tension force retaining ring 100 comprises outer fixed ring 150 and is coaxially arranged on the interior fixed ring 110 in outer fixed ring 150, described outer fixed ring 150 inner sides are provided with the kinetic energy slip ring 160 that drive unit drives rotation, in described interior fixed ring 110, be coaxially arranged with the annular fan that can slide in described interior fixed ring, described annular fan by large ring frame 131 and little ring frame 132 fixedly flabellum 120 form, the arranged outside of described large ring frame 131 has the clutch ring element 140 with the variable-diameter of described outer fixed ring 150 inner side kinetic energy slip ring 160 frictional fit, described clutch ring element 140 is the clutch with described kinetic energy slip ring 160 by control module control.
Described control module is controlled described clutch ring element 140 and described kinetic energy slip ring 160 interlocks when yarn breakage, makes the annular fan can be driven, the air-flow of the fan-shaped one-tenth of described annular, and air-flow brushes yarn and forms tension force.
Above-mentioned broken yarn tension force holding device, described tension force retaining ring 100 is arranged on the middle part of yarn 10 transmission locus.
Above-mentioned broken yarn tension force holding device, in described interior fixed ring 110, slide and be provided with two annular fans that air blast direction is different, described tension force retaining ring 100 is arranged on the middle part of yarn 10 transmission locus, when a side in tension force retaining ring 100 of the breakaway poing of yarn 10, brush the clutch ring element 140 interlock kinetic energy slip rings 160 of the annular fan of this side.
