Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textile production, in particular to a braid yarn eliminating device for a crawler-type warping machine. Background Art
[0002] In cotton textile production, functional filament staple fiber wrapped yarn is a new type of yarn formed by combining two or more fibers. These fibers are mostly functional polymer materials, with a core made of a filament material known for its strength, elasticity, and cut resistance. The wrapped yarn is then twisted and spun together with the corresponding functional staple fibers. This differentiated sheath-core structure combines the excellent properties of both a filament core and a staple fiber wrapper.
[0003] When warping filament staple fiber covered structural yarns before weaving, traditional V-shaped warping machines typically use a tension rod-based warping tension adjustment method. In production practice, this often results in the formation of small braids during the slow warping of covered structural yarn joints. This is because the yarn is subjected to uneven tension during unwinding, causing some yarn to relax. This, combined with internal torque or inertia, creates a kink, forming a braid-like shape that cannot be untied. These small braids significantly impact subsequent production, resulting in cosmetic defects in the finished fabric, reduced physical properties, and, in severe cases, even disrupting production. Summary of the Invention
[0004] In order to overcome the shortcomings of the existing technology, the purpose of the invention of the utility model is to provide a crawler-type warping machine to eliminate braided yarn device, so as to avoid the filament staple fiber coated structure yarn from twisting and forming braids during the warping process, affecting the subsequent product production, and improving the warping quality.
[0005] In order to achieve the above-mentioned purpose of the invention, the utility model provides a crawler-type warping machine device for eliminating small braided yarns, including a bobbin, a wire baffle, and a double-disc roller tension device. The yarn led out from the bobbin mounted on the yarn frame passes through the wire guide porcelain eye of the wire baffle, the double-disc roller tension device, and the wire guide porcelain plate in sequence and enters the warping machine head to form a warp shaft. The bobbin is covered with a warping anti-braid belt for eliminating small braided yarns.
[0006] Furthermore, the warping anti-braid belt includes a covering cloth belt and a pressure steel bar. Several pressure steel bars are fixed at equal intervals inside the covering cloth belt, and the spacing between the pressure steel bars is greater than the outer circumference of the bobbin yarn.
[0007] Furthermore, the warping and anti-braiding belt is a rectangular flat cloth bag, the width of the warping and anti-braiding belt is greater than the height of the bobbin yarn, and the warping and anti-braiding belt covers and fits tightly against the upper half of the bobbin yarn.
[0008] Furthermore, the double-disc roller tension device includes a core shaft and a tension disk, and the wire blocking plate is fixed on the column.
[0009] Compared with the prior art, the utility model can limit the yarn movement trajectory when the bobbin yarn of the short fiber filament covered structural yarn is warped and unwound, reduce the twisting effect caused by large movement of the yarn during the unwinding process, avoid the twisting effect caused by changes in vehicle speed, effectively control the occurrence of small braids caused by uneven tension, and improve the warping efficiency and the warping quality of the warp beam.

Typically, there are nine pressure steel bars 10, each equidistantly embedded and fixed within a covering tape 9. This divides the covering tape 9 into eight equal sections, covering eight bobbins (the spacing between the warping machine frame columns is uniform across the eight bobbins). The pressure steel bars 10 are φ8 mm x 15 cm, and the covering tape 9 is 20 cm wide and 419 cm long.
[0018] Preferably, the warping anti-braid belt 8 is a rectangular flat cloth bag, the width of the warping anti-braid belt 8 is greater than the height of the bobbin 2, and the warping anti-braid belt 8 covers and fits tightly against the upper half of the bobbin 2.

[0020] When in use, during the warping process of the filament staple coated structural yarn, the warping anti-braid belt 8 is covered and tightly attached to the upper half of the bobbin yarn 2, which can effectively limit the yarn unwinding activity trajectory of the bobbin yarn 2, control the large-scale movement of the yarn during unwinding to produce twisting, avoid yarn twisting caused by changes in vehicle speed, effectively avoid the occurrence of small braided yarns, and improve the warping efficiency and warp beam quality.
