[0004] In the existing technology, CN217378169U can provide a certain buffering effect on the weft tube and the weft when the loom stops. However, when the weft is extracted, the existing weft tube has poor stability. As the weft is extracted, the weft tube will shake left and right. Therefore, a circular weft yarn tube is needed to solve the above problem. Utility Model Content

[0005] The utility model aims to provide a circular weft yarn tube, which has the advantage of improving the stability of the weft tube when the weft is drawn, and solves the problem that the weft tube will shake greatly as the weft is continuously drawn.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a circular weft yarn tube, comprising a base and a sleeve, wherein a second connecting ring and a first connecting ring are fixedly installed at the upper and lower ends of the sleeve respectively, a screw body passes through the sleeve, a first limit block is fixedly installed at the bottom end of the screw body, the top of the screw body passes through the sleeve and is movably sleeved with a second limit block, the top of the screw body passes through the second limit block and is threadedly installed with a nut body.

[0007] When using a circular weft yarn tube in the technical solution, the base is fixed to the thread taking-up position of the circular loom through the installation bolts, and the first limit block is inserted into the base through the pin, and the screw body is passed through the sleeve. At this time, the second limit block is mounted on the top of the sleeve and clamped by the nut body. At this time, the weft yarn wrapped on the sleeve is extracted by the circular loom. Since the first limit block and the second limit block clamp the sleeve, the stability of the weft yarn tube is provided when the weft yarn is extracted.

[0008] Preferably, the sleeve is made of stainless steel, and the diameters of the upper and lower ends of the sleeve are the same.

[0009] Preferably, the first limit block adopts a hemispherical structure design, the first limit block is movably mounted on the upper surface of the base, and a latch is fixedly mounted on the lower surface of the first limit block.

[0010] Preferably, holes are respectively opened at the four corners of the upper surface of the base and mounting bolts are movably installed thereon, and a limiting groove is opened in the middle of the upper surface of the base.

[0011] Preferably, the cross section of the latch adopts a hexagonal structure design, and the latch is movably inserted into a limiting groove on the upper surface of the base.

[0012] Preferably, the second limiting block adopts a spherical structure design, the outer diameter of the second limiting block matches the outer diameter of the first limiting block, and a reserved groove is opened in the second limiting block.

[0013] Preferably, the screw body passes through the second limit block through the reserved groove, and the outer wall of the screw body does not contact the inner wall of the reserved groove.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] The utility model provides a first limit block and movably inserts the first limit block on the base, thereby preventing the weft tube from falling off when the weft is drawn out. At the same time, the top of the sleeve is clamped by the second limit block, so that the sleeve can remain vertical to the base when the weft is drawn out, thereby achieving the effect of improving the stability of the weft tube when the weft is drawn out.
