Abstract

The invention provides a yarn tension control structure. The yarn tension control structure comprises guide roller pairs used for conveying yarns. Rotary supports are arranged on the two sides of each guide roller pair. Each rotary support rotates with the conveying track of the yarns in the guide roller pairs serving as the axis. A yarn guide ring is fixed to each rotary support through a rocker arm which is arranged in the radial direction, and the yarns pass through the yarn guide rings. The yarn guide rings of the rotary supports between every two adjacent guide roller pairs rotate synchronously and correspondingly. According to the yarn tension control structure, the yarns are driven by the rotation of the yarn guide rings to rotate in a mode similar to rope jumping, the yarns keep rotating at the breaking moment, and the yarns keep tension in a certain time under the action of centrifugal force.

Description

A kind of yarn tension control structure
Affiliated technical field
The present invention relates to textile machine apparatus field, especially, is a kind of control structure of controlling yarn tension.
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, point comb is rotary.The stop over postures that adopt 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.When 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.In the time of 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 yarn is general in transmitting procedure adopts flexible pinch roller to carry out tensioner to yarn, keeps the straight property of yarn transmission locus, but once yarn ruptures, and yarn will disorderly be gone here and there, very easily causes second accident.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of yarn tension control structure, this yarn tension control structure can keep tension force after yarn breakage.
The technical solution adopted for the present invention to solve the technical problems is:
This yarn tension control structure comprises the deflector roll pair that transmits yarn, each deflector roll is provided with rotary support to both sides, described rotary support is rotated taking the transmission locus of deflector roll centering yarn as axis, described rotary support is fixed a yarn guiding ring by a rocking arm radially arranging, yarn is through described yarn guiding ring, every two adjacent deflector rolls between the synchronous corresponding rotation of yarn guiding ring of described rotary support.
As preferably, described yarn guiding ring uses wire to carry out ground connection.
As preferably, in described yarn guiding ring, be coaxially arranged with the slip ring of slip, yarn is through described slip ring.
As preferably, the outside of described yarn guiding ring rotational trajectory is enclosed with the spacing bobbin with the coaxial setting of described rotary support.
The invention has the advantages that:
After described yarn ruptures, because described yarn is under the drive of described yarn guiding ring rotation, the same rotation of similar rope skipping, also keeps rotation a moment of yarn breakage, and under the effect due to centrifugal force, described yarn keeps within a certain period of time tension force under the effect of centrifugal force.
Brief description of the drawings
Fig. 1 is the structural representation of this yarn tension control structure.
Fig. 2 is the structural representation of this yarn tension control structure rotary support and yarn guiding ring.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
In the present embodiment, consult Fig. 1 and Fig. 2, this yarn tension control structure comprises that the deflector roll that transmits yarn 10 is to 300, each deflector roll is provided with rotary support 200 to 300 both sides, described rotary support 200 is rotated as axis the transmission locus of yarn 10 in 300 taking deflector roll, described rotary support 200 is fixed a yarn guiding ring 100 by a rocking arm 210 radially arranging, yarn 10 is through described yarn guiding ring 100, the yarn guiding ring 100 synchronous corresponding rotation of every two adjacent deflector rolls to the described rotary support 200 between 300.
Above-mentioned yarn tension control structure, described yarn guiding ring 100 uses wire to carry out ground connection, prevents that friction from producing too much static.
Above-mentioned yarn tension control structure, in described yarn guiding ring 100, be coaxially arranged with the slip ring 110 of slip, yarn 10 is through described slip ring 110, due to the existence of described slip ring 110, described yarn 10 can produce static friction with described slip ring, keep fixing relative position, further reduce the friction with yarn 10.
Above-mentioned yarn tension control structure, the outside of described yarn guiding ring 100 rotational trajectories is enclosed with the spacing bobbin 400 with the coaxial setting of described rotary support 200, after yarn 10 ruptures, yarn 10 is thrown out of, described spacing bobbin 400 can limit the position of described yarn 10, yarn 10 can obtain frictional force on spacing bobbin 400 simultaneously, and this frictional force can to a certain degree assist yarn 10 to form the post-rift tension force of yarn 10.
The working method of above-mentioned yarn tension control structure and principle:
After described yarn 10 ruptures, under the drive of rotating at described yarn guiding ring 10 due to described yarn 10, the same rotation of similar rope skipping, also keep rotation a moment of yarn breakage, under effect due to centrifugal force, described yarn 10 keeps within a certain period of time tension force under the effect of centrifugal force, this time just in time transition loom run to the time delay stopping.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
