Description

Technical Field

[0001] This utility model relates to the field of circular loom technology, and more specifically, it relates to an inclined track structure for a suspended circular loom. Background Technology

[0002] A circular loom is a common type of weaving equipment. The warp frame of a circular loom has many spindles. The number of warp yarns used is within a specified range according to the width of the woven fabric and the width of the flat yarn. Before the warp yarns enter the circular loom, the warp yarn frame makes a cross opening between the warp yarns. The weft shuttle moves in a circular motion through the warp yarns in the cross opening to weave into a tube fabric.

[0003] When a circular loom is working, the shuttle moves in a circular motion along the pivot on the gate ring to complete the weaving process. For example, utility model patent No. 2018216214095 discloses a gate ring assembly for a circular loom, including an upper gate ring and a lower gate ring. A roller assembly is provided between the upper and lower gate rings, with several roller assemblies arranged circumferentially along the gate ring assembly. Each roller assembly includes rollers and roller shafts. The rollers are installed between the upper and lower gate rings via the roller shafts. A warp thread passage is formed between the lower surface of the upper gate ring, the upper surface of the lower gate ring, and adjacent roller assemblies. The rollers in this assembly are cylindrical. During operation, the outer circumference of the rollers engages with the shuttle to support it. However, since this roller assembly only provides radial support to the shuttle and not axial support, it suffers from poor stability. The shuttle tends to swing up and down during circular motion, thus affecting the weaving quality. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a slanted track structure for a suspended circular loom.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0012] The present invention further comprises: an upper seat and a lower seat are respectively provided at the upper and lower ends of the mounting base, the upper seat and the lower seat are inclined relative to each other, wherein the upper guide wheel and the lower guide wheel are respectively rotatably mounted on the upper seat and the lower seat via a rotating shaft.

[0013] The present invention further comprises: the upper and lower ends of the limiting wheel are respectively installed between the upper and lower seats via the upper mounting base and the lower mounting base.

[0014] The present invention further comprises: the upper mounting base having an upper slot adapted to the lower end of the upper base, and the lower mounting base having a lower slot adapted to the upper end of the lower base.

[0026] See attached document Figures 1 to 6 The present invention provides a more detailed description of the inclined track structure of a suspended circular loom.

[0027] A slanted track structure for a suspended circular loom includes a shuttle 3 and a track for the shuttle 3 to slide on; the track includes an upper gate ring 1, a lower gate ring 2 and several guide wheel assemblies 4 arranged opposite to each other, and the guide wheel assembly 4 includes a mounting base 41, an upper guide wheel 42 and a lower guide wheel 43 and a limiting wheel 44;

[0028] The upper guide wheel 42 and the lower guide wheel 43 are respectively rotatably mounted on the upper and lower ends of the mounting base 41, wherein the upper guide wheel 42 and the lower guide wheel 43 are inclined relative to each other;

[0029] The limiting wheel 44 is rotatably disposed in the middle of the mounting base 41, and the side wall of the limiting wheel 44 is recessed inward to provide a limiting groove 441;

[0030] The shuttle 3 is provided with a limiting block 31 that matches the limiting groove 441. The upper end of the shuttle 3 is inclined with an upper sliding surface 32 that cooperates with the upper guide wheel 42, and the lower end is inclined with a lower sliding surface 33 that cooperates with the lower guide wheel 43. The upper sliding surface 32 and the lower sliding surface 33 of the shuttle 3 slide along the upper guide wheel 42 and the lower guide wheel 43 respectively, so that the shuttle 3 makes a circular motion between the upper gate ring 1 and the lower gate ring 2. During this process, the limiting block 31 on the shuttle 3 cooperates with the limiting groove 441 on the limiting wheel 44. That is, when the shuttle 3 makes a circular motion along the track, the limiting block 31 on the shuttle 3 is always placed in the limiting groove 441 of the corresponding guide wheel. At the same time, the upper guide wheel 42 and the lower guide wheel 43 press the shuttle 3 from different directions, which will limit the displacement of the shuttle 3 in the axial and radial directions, improve the stability of the shuttle 3 operation, and ensure the weaving quality of the circular loom.

[0031] The limiting groove 441 is arc-shaped, which allows the limiting block 31 to move axially more smoothly along the limiting groove 441, and allows the shuttle 3 to slide more smoothly on the track.

[0032] The outer walls of the limiting wheel 44 and the guide wheel are provided with rubber layers to prevent the limiting block 31 from directly contacting the limiting wheel 44 and to prevent the shuttle 3 from directly contacting the guide wheel and causing wear; thus improving the product's service life.

[0033] The mounting base 41 is provided with an upper base 411 and a lower base 412 at its upper and lower ends, respectively. The upper base 411 and the lower base 412 are inclined relative to each other. The upper guide wheel 42 and the lower guide wheel 43 are rotatably mounted on the upper base 411 and the lower base 412 respectively via a rotating shaft. The upper guide wheel 42 and the lower guide wheel 43 are inclined relative to each other on the mounting base 41, which generates a pressing force on the shuttle 3 in different directions, thereby limiting the shuttle 3 in the axial and radial directions.

[0034] The upper and lower ends of the limiting wheel 44 are respectively mounted between the upper seat 411 and the lower seat 412 via the upper mounting seat 5 and the lower mounting seat 6. The upper mounting seat 5 and the lower mounting seat 41 are respectively fixed to the mounting seat 41 with fastening screws. The upper mounting seat 5 is provided with an upper slot 51 that matches the lower end of the upper seat 411, and the lower mounting seat 6 is provided with a lower slot 61 that matches the upper end of the lower seat 412. When assembling the limiting wheel 44, the limiting wheel 44 is assembled between the upper mounting seat 5 and the lower mounting seat 6 via a rotating shaft. Then, the upper mounting seat 5 and the lower mounting seat 6 are respectively inserted into the lower end of the upper seat 411 and the upper end of the lower seat 412 via the upper slot 51 and the lower slot 61. Finally, the upper mounting seat 5 and the lower mounting seat 6 are fixed to the mounting seat 41 with fastening screws, which can realize the quick assembly of the limiting wheel 44.

[0035] The limiting wheel 44 and the guide wheel are both equipped with bearings 7. The limiting wheel 44 and the guide wheel are rotatably mounted on the rotating shaft through the bearings 7, which reduces the friction generated by the rotation of the limiting wheel 44 and the guide wheel relative to the rotating shaft, so that the limiting wheel 44 and the guide wheel rotate more smoothly relative to the rotating shaft.

[0036] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
