[0002] The warping process is a process of parallel winding a certain number of warp yarns on a warp beam or a weaving beam according to a specified length and width. The warping requires that the tension of each warp yarn is equal, the warp yarns are uniformly distributed on the warp beam or the weaving beam, and the color yarns are arranged according to the process requirements. In the process of transporting the yarn from the bobbin mounting frame to the warping machine, a guide plate is added between the bobbin mounting frame and the warping machine to ensure the tension and neatness of the yarn. In the process of adjusting the guide plate, in order to prevent the yarn from breaking, the periphery of the yarn guide hole on the guide plate is generally provided with a certain fillet structure, or other yarn guide pieces with a fillet structure are additionally provided in the yarn guide hole. The yarn guide piece with a fillet structure is prone to wear during long-term use, and it is difficult to maintain and replace. Although there is a design of a detachable combined guide piece in the prior art, such as the detachable guide piece of the yarn guide plate of the warping machine disclosed in Chinese patent CN208121289U, for the working conditions of a thin guide plate or a small space reserved for the guide piece, the installation operation of the combined guide piece is not convenient, and the combined guide piece occupies a large space. Not only does it affect the stability of the structure of the yarn guide plate, but also it is not easy to ensure the stability of the structure of the two guide pieces during long-term use. Therefore, it is necessary to improve the structure of the thin-wall guide piece. SUMMARY

Therefore, the features defined with "first", "second" and the like can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0023] In the description of the present application, it should be noted that unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0024] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0025] A guide for a beaming machine guide plate, as shown in Figures 1 to 5 The connecting plate is integrally formed with the guide sleeve, has high structural strength and good stability. An inner end guide structure 3 is formed at the junction of the inner wall of the guide sleeve and the connecting plate, and as an example, the inner end guide structure includes an arc-shaped guide surface. The guide sleeve has an equal diameter structure, and a positioning table 4 is formed at the junction of the outer wall of the guide sleeve and the connecting plate, that is, the axial direction of the guide sleeve is perpendicular to the plane of the connecting plate.

[0026] When installed and used, the guide provided by the present application is inserted into the mounting hole of the guide plate, and positioning is formed by the positioning table between the guide sleeve and the connecting plate, so that the guide and the guide plate are reliably positioned, and the connecting plate and the guide plate 10 are fixed by using a connecting member (such as a screw), so as to ensure that the structure of the guide and the guide plate is stable and reliable.

[0027] In the scheme of fixing the connecting plate and the thread guide plate by the connecting piece, a plurality of fixing holes 5 are arranged on the connecting plate, the screw 11 is arranged in the fixing hole, and then the screw is tightened to fix the connecting plate on the thread guide plate. Of course, the connecting plate and the thread guide plate can also be fixed by gluing. When fixed by gluing, magnetic glue can be used, as long as the guide piece can be disassembled. The connection and fixing mode between the connecting plate and the thread guide plate can be selected by the person skilled in the art according to the actual needs. Since it is a conventional technical means of prior art, it will not be described here.

[0028] An outer end guide structure 6 is arranged at the inner wall of the free end of the guide sleeve. Specifically, the outer end guide structure includes a ring-shaped protrusion protruding from the inner wall of the guide sleeve. The ring-shaped protrusion includes a wire passing guide surface 7 facing the connecting plate side and a wire outlet guide surface 8 away from the connecting plate side, and an arc-shaped transition part 9 is formed at the junction of the wire passing guide surface and the wire outlet guide surface. The length of the wire passing guide surface along the axial direction of the guide sleeve is greater than the length of the wire outlet guide surface along the axial direction of the guide sleeve.

[0029] Usually, the connecting plate is fixed to the inner side of the thread guide plate. When the guide piece is installed and used, the guide sleeve passes through the guide piece mounting hole on the thread guide plate, the connecting plate abuts against the inner side surface of the thread guide plate, and the free end of the guide sleeve protrudes from the thread guide plate. As an example, the length of the free end of the guide sleeve extending out of the thread guide plate is 1-2 mm. In the case of limited radial space, the structural stability of the guide piece during use can be effectively improved by appropriately increasing the axial length, and it is ensured that the yarn only contacts the guide piece during passing and does not touch the thread guide plate. In addition, since the outer end guide structure has an inward ring-shaped protrusion, it has the effect of gathering the yarn towards the center of the guide piece during the passing of the yarn. The wire outlet end is limited and guided by the outer end guide structure, and the yarn contacts the surface of the outer end guide structure smoothly. The wire outlet process is stable, and yarn breakage is avoided.

[0030] In an optional embodiment, the length of the arc-shaped guide surface of the inner end guide structure along the axial direction of the guide sleeve is 1 / 3-3 / 4 of the thickness of the connecting plate. The inner end guide structure is designed at the thick part of the junction of the guide sleeve and the connecting plate, so the inner end guide structure has very good wear resistance. The diameter of the smallest inner diameter of the transition part is 3-5 mm smaller than the inner diameter of the guide sleeve, that is, the protrusion height of the outer guide structure on the inner wall of the guide sleeve is about 1.5-2.5 mm. Therefore, the outer end guide structure also has very good wear resistance, so that the guide piece is suitable for long-term use.

[0031] Preferably, the connecting plate is rounded at each corner. The guide sleeve is rounded at each corner. The transition between the wire guide surface and the inner wall of the guide sleeve is smooth. The transition between the wire exit guide surface and the end surface of the free end of the guide sleeve is rounded. The corners of the guide are rounded, which makes the installation smooth and does not scratch other structural components. When the yarn passes through the guide, the friction with the inner end guide structure and the outer end guide structure is very small.

[0032] The present application has simple structure and reasonable design. The connecting plate and the guide sleeve are designed in an integrated structure, which has high structural strength, is easy to install and use, and has good stability. The inner end guide structure is an arc-shaped guide surface at the thick part of the joint between the guide sleeve and the connecting plate. The outer end guide structure is a protrusion provided on the inner wall of the free end of the guide sleeve. The wear resistance is excellent, and the guide can be used stably for a long time. The yarn is guided when passing through the guide plate, and the yarn breakage is effectively avoided. Even if the guide is worn after long-term use, the guide can be individually disassembled and replaced.

[0033] The above description is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
