A deflection guide for a weaving machine

Abstract

This utility model discloses a yarn guide for a loom, relating to the field of textile technology. It includes a cross-shaped insert rod through which a yarn guide disc is inserted. Hexagonal nuts are movably sleeved on both sides of the yarn guide disc. This utility model solves the problems of existing yarn guide devices having high contact friction with the yarn, making it difficult to ensure stability, and the yarn guide needing to fix multiple sets of weft yarns. This utility model addresses these issues by using a cross-shaped insert rod to insert the yarn guide disc. The rotation of the cross-shaped insert rod can drive multiple sets of yarn guide discs to rotate synchronously. The number of yarn guide discs is variable and can be added as needed. The corresponding arrangement of the yarn guide discs and hexagonal nuts, along with the offset grooves, reduces the contact area between the textile yarn and the discs. Rounded corners further reduce frictional resistance. The side-connecting components, combined with the hexagonal nuts, achieve double-sided fixation of the yarn guide disc, ensuring stability during rotation.

Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically to a diverting yarn guide for a loom. Background Technology

[0002] A guide yarn changer can change the direction of the weft yarn, ensuring that the weft yarn can smoothly enter the shed, thereby completing the weft yarn threading process. A guide yarn changer usually consists of a fixed frame and one or more rotatable guide wheels.

[0003] The adjustable yarn guide with authorization announcement number CN220467158U includes a limiting device, a guiding device, a yarn guide slide, a fixed guide groove, and a limiting bracket. By setting the guiding device, when the yarn is guided and adjusted at multiple angles, the connecting handwheel can drive the transmission worm gear to rotate precisely through the transmission worm. This allows the transmission worm gear to slide and limit the fixed slide, thereby driving the fixed slide to rotate precisely on the upper part of the support guide plate. This allows for precise control of the angle of yarn guidance by the positioning ring and the yarn guide slide. However, the contact friction between the guiding device and the yarn is relatively large, and the weaving direction is controlled by the handwheel, making it easy for the guiding device to turn under the control of the yarn, which makes it difficult to guarantee its stability. At the same time, the yarn guide needs to meet the function of fixing multiple sets of weft yarns.

[0004] To address the aforementioned problems, a diverting yarn guide for looms is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a steering guide for a loom, which solves the problems in the prior art where the contact friction between the existing guide device and the yarn is large, and the weaving direction is controlled by a handwheel, making it easy for the guide device to turn under the control of the yarn, making it difficult to ensure its stability. At the same time, the guide needs to meet the function of fixing multiple sets of weft yarns.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a yarn guide for a loom, comprising a cross-shaped insert rod, through which a yarn guide turntable is inserted, and hexagonal nuts are movably sleeved on both sides of the yarn guide turntable. The yarn guide turntable includes a disc, on which three sets of offset grooves are arranged in a circular array. A guide opening is correspondingly opened at the center of each offset groove. A feeding port is opened on one side of the disc. The edge of the disc is rounded. Side connecting components are provided on both sides of the disc.

[0007] Preferably, the cross-shaped insertion rod is aligned with the center of the guide wire turntable.

[0008] Preferably, the side-connecting assembly further includes cylindrical side inserts fixedly disposed on both sides of the disc, and a threaded block is fixedly disposed on one side of each cylindrical side insert.

[0009] Preferably, the threaded block has four cuts on one side.

[0010] Preferably, a limiting plate is fixedly provided on one side of the threaded block, and the radius of the limiting plate is larger than the opening of the hexagonal nut.

[0011] Preferably, the center of the disc and the side connector assembly has a cross-shaped through-hole corresponding to the cross-shaped insert.

[0012] Preferably, the side-mounted assembly is provided with two sets that are mirror-symmetrical about the disk.

[0013] Preferably, the hexagonal nut has internal threads.

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

[0015] 1. This utility model provides a yarn guide for a loom, which uses a cross-shaped insert rod to insert the yarn guide disc. The rotation of the cross-shaped insert rod can drive multiple yarn guide discs to rotate synchronously. The number of yarn guide discs is not fixed and can be added as needed, which solves the problem that the existing yarn guide device needs to meet the function of fixing multiple weft yarns.

[0016] 2. This utility model provides a yarn guide for a loom. Through the corresponding arrangement of the yarn guide turntable and the hexagonal nut, the feed port conveys the yarn to the guide port. The offset groove reduces the contact area between the yarn and the turntable. The rounded corners reduce frictional resistance. The side connection component and the hexagonal nut are used to fix the yarn guide turntable on both sides, ensuring the stability of the yarn guide turntable when it rotates. This solves the problem that the existing yarn guide device has a large contact friction with the yarn, and the weaving direction is controlled by a handwheel, making it easy for the guide device to turn under the control of the yarn, which makes it difficult to ensure its stability.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0025] Combination Figure 1 This utility model discloses a yarn guide for a loom, comprising a cross-shaped insert 1, through which a yarn guide turntable 2 is inserted. Hexagonal nuts 3 are movably sleeved on both sides of the yarn guide turntable 2. The yarn guide turntable 2 includes a disc 21, on which three sets of offset grooves 211 are arranged in a circular array. A guide opening 212 is correspondingly opened at the center of the offset grooves 211. A feeding opening 213 is opened on one side of the disc 21. The edge of the disc 21 is rounded 22. Side connecting components 23 are provided on both sides of the disc 21.

[0026] Specifically, the guide disc 2 is inserted through the cross-shaped insert 1. The rotation of the cross-shaped insert 1 can drive multiple guide discs 2 to rotate synchronously. The feeding port 213 feeds the textile thread to the guide port 212. The opening of the offset groove 211 reduces the contact area between the textile thread and the disc 21. The rounded corner 22 reduces the frictional resistance. The side connection component 23 and the hexagonal nut 3 are used to fix the guide disc 2 on both sides, ensuring the stability of the guide disc 2 when rotating. The number of guide discs 2 is not fixed and can be added according to needs. The guide disc 2 can move or turn synchronously with the cross-shaped insert 1.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example 1:

[0029] Combination Figures 2-5 The cross-shaped insertion rod 1 is aligned with the center of the guide wire turntable 2. The cross-shaped arrangement allows the fixed direction of the guide wire turntable 2 to change by ninety degrees without affecting the rotation of the guide wire turntable 2.

[0030] The side connection assembly 23 also includes cylindrical side inserts 231 fixedly disposed on both sides of the disc 21. A threaded block 232 is fixedly disposed on one side of the cylindrical side insert 231. The cylindrical side insert 231 and the threaded block 232 have the same radius at one end, which facilitates the rotational connection of the hexagonal nut 3. The side of the threaded block 232 away from the cylindrical side insert 231 has a larger radius, which facilitates the rotational compression of the hexagonal nut 3.

[0031] The threaded block 232 has four slits 233 on one side. The slits 233 make one end of the threaded block 232 adjustable. It can be pressed and fixed with the hexagonal nut 3.

[0032] A limiting plate 234 is fixedly installed on one side of the threaded block 232. The radius of the limiting plate 234 is larger than the opening of the hexagonal nut 3. The limiting plate 234 limits the hexagonal nut 3 to prevent it from leaving the fixed range of the guide wire turntable 2.

[0033] The center of the disc 21 and the side connection assembly 23 is provided with a cross-shaped through-hole 24 corresponding to the cross-shaped insertion rod 1. The opening of the cross-shaped through-hole 24 corresponds to the cross-shaped insertion rod 1, which facilitates the overall control of the guide wire turntable 2 by the cross-shaped insertion rod 1.

[0034] Example 2:

[0035] Combination Figure 4 and Figure 5 The side connection component 23 is provided in two sets that are mirror-symmetrical about the disc 21. The two sets of side connection components 23 are provided to fix the guide wire turntable 2 at both ends and maintain stability.

[0036] The hexagonal nut 3 has internal threads, which correspond to the external threads of the threaded block 232, thus completing the rotational connection.
