Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a device for preventing elastic yarn from being twisted and woven into a cloth surface. Background Art

[0002] Stretch yarn fabrics are smooth and breathable, with good comfort and hygiene, and are ideal clothing fabrics for all seasons. However, stretch yarns have high twist and are unstable, and are prone to kinking during the weaving process, resulting in defective products with many kinks and weaving defects on the surface.

[0003] The reasons why stretch yarns get tangled during the weaving process are: 1. The yarn twist is high, which makes it easy to curl and become unstable during the weaving process; 2. The yarn tension is inevitably relaxed and tangled when the weft yarn is unwound during the weaving process.

[0004] In the prior art, the device for unwinding the yarn has high manufacturing cost and complex structure. Therefore, it is necessary to prevent the yarn from being tangled and woven into the cloth surface by a friction device with simple structure and low manufacturing cost at the beginning of the yarn unwinding.

[0023] The present invention is described in detail below in conjunction with specific embodiments.

[0024] In the present utility model, when directional words appear, they are used to facilitate the description of the utility model and simplify the description, rather than to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific protection scope of the present utility model.

[0025] In the present invention, unless otherwise specified and limited, when terms such as "disposed on", "connected" and "connected" appear, these terms should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection; it can be directly connected, or it can be connected through an intermediate medium, or the two elements can be internally connected. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] like Figures 1 to 3 As shown, a device for preventing elastic yarn from being twisted and woven into a fabric surface comprises a bobbin sleeve 10, a wire tube 20 and a connecting support 30.

[0027] The bobbin seat 10 is in a truncated cone shape, and is used to facilitate the installation of the bobbin 3 wound with the yarn 1 on the bobbin seat 10 . A through hole 11 is vertically provided at the center of the bobbin seat 10 for connecting the wire tube 20 .

[0028] The wire tube 20 is passed through the through hole 11 at the upper and lower ends of the bobbin sleeve 10. The inside of the wire tube 20 is a hollow structure, and the yarn 1 is wound around the wire tube 20 when the yarn 1 is withdrawn from the bobbin 3 to increase the friction force, and then the yarn 1 is led out to connect the weft storage device 2 after passing through the wire tube 20. The wire tube 20 can be a single integral structure wire tube 20, or a split structure wire tube 20 can be passed through the through hole 11 of the bobbin sleeve 10.

[0029] The connecting support 30 is vertically connected to the bottom of the bobbin sleeve 10 to support and elevate the bobbin sleeve 10. A fixed connecting hole 33 is provided at the bottom of the connecting support 30 for fixed connection to the mobile frame to facilitate movement and use.

[0030] In a specific implementation, the yarn bobbin 3 wound with the yarn 1 is installed on the bobbin sleeve 10, the yarn 1 is led out, and is wound on the wire tube 20 at the upper end of the bobbin sleeve 10 in a spiral manner to increase the friction when the yarn is withdrawn, and then the yarn 1 is inserted into the wire tube 20, and the yarn 1 is led out from the wire tube 20 at the lower end of the bobbin sleeve 10 into the weft storage device 2, so that when the yarn 1 is withdrawn from the yarn bobbin 3, the tension of the yarn 1 can be effectively prevented from being relaxed, clumped and tangled, and the device has a simple structure, a low manufacturing cost and strong practicality.

[0031] In this embodiment, the wire tube 20 includes an upper wire tube 21 and a lower wire tube 22 . The length of the upper wire tube 21 is greater than or equal to the length of the lower wire tube 22 . The lower end of the upper wire tube 21 and the upper end of the lower wire tube 22 are both inserted into the through hole 11 .

[0032] The upper wire tube 21 and the lower wire tube 22 are adjustably and telescopically arranged in the through hole 11, so that the yarn 1 can be wound around the upper wire tube 21 for more turns to increase the friction force when the yarn is withdrawn.

[0033] Specifically, the lower end of the upper wire tube 21 and the upper end of the lower wire tube 22 are connected to the through hole 11 through threads, and the upper wire tube 21 and the lower wire tube 22 are rotated to perform telescopic adjustment in the through hole 11.

[0034] In addition, in order to prevent the yarn 1 from being worn when being introduced into and led out of the wire tube 20, the inner and outer peripheral edges of the lower end of the upper wire tube 21 and the upper end of the lower wire tube 22 are both provided with rounded corners.

[0035] In this embodiment, the connecting support 30 includes a support rod 31 and a base plate 32. The support rod 31 is relatively spaced apart on both sides of the wire tube 20 to avoid interference with the yarn 1 led out of the lower wire tube 22. The lower end of the support rod 31 is vertically connected to the base plate 32, and a fixed connecting hole 33 is arranged on the base plate 32.

[0036] Compared with the prior art, the utility model provides a device for preventing elastic yarn from being twisted and woven into a fabric. When the yarn 1 is unwound on the yarn tube 3, the yarn 1 can be effectively prevented from being loosened, clumped and twisted. The device has a simple structure, low manufacturing cost and strong practicality.

[0037] In the absence of conflict, the above-mentioned embodiments and features thereof may be combined with each other.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
