Description

Technical Field

[0001] This utility model relates to the field of circular loom technology, and in particular to a suspended circular loom track structure. 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 CN209227152U 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, and 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. Specifically, the shuttle tends to swing up and down during circular motion, affecting the weaving quality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a suspended circular loom track structure.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a suspended circular loom track structure, including a gate ring assembly and a shuttle. The gate ring assembly includes an upper gate ring and a lower gate ring, and a rotating shaft disposed between the upper gate ring and the lower gate ring. A guide wheel is provided in the middle of the rotating shaft, and at least one limiting wheel is provided at each of the upper and lower ends of the rotating shaft. The side of the limiting wheel is provided with an inwardly recessed limiting groove. The outer side of the shuttle contacts the guide wheel and is provided with a limiting protrusion corresponding to the limiting groove.

[0006] The cross-section of the limiting groove is trapezoidal.

[0007] The cross-section of the limiting protrusion is arc-shaped.

[0008] The door ring assembly also includes a mounting base, through which the pivot is mounted between the upper and lower door rings.

[0009] The mounting base includes an upper base, a lower base, and a connecting plate. The upper and lower ends of the connecting plate are connected to the upper base and the lower base, respectively. Both the upper base and the lower base are provided with shaft holes, and the upper and lower ends of the rotating shaft are rotatably disposed in the corresponding shaft holes.

[0010] The outer walls of the limiting wheel and the guide wheel are provided with a rubber layer.

[0011] The beneficial effects of this utility model are as follows: When the shuttle of this utility model makes a circular motion within the gate assembly, the outer surface of the shuttle cooperates with the guide wheel, the limiting protrusion of the shuttle cooperates with the limiting groove of the limiting wheel, the guide wheel provides radial support for the shuttle, and the limiting wheel provides axial support for the shuttle, thereby limiting the axial and radial displacement of the shuttle, improving the stability of the shuttle operation, and ensuring the weaving quality of the circular loom.

[0017] A suspended circular loom track structure includes a gate ring assembly and a shuttle 10. The gate ring assembly includes an upper gate ring 21 and a lower gate ring 22, and a rotating shaft 31 disposed between the upper gate ring 21 and the lower gate ring 22. A guide wheel 32 is provided in the middle of the rotating shaft 31. At least one limiting wheel 33 is provided at the upper and lower ends of the rotating shaft 31. The limiting wheel 33 has an inwardly recessed limiting groove 34 on its side. The outer side of the shuttle 10 contacts the guide wheel 32 and has a limiting protrusion 11 corresponding to the limiting groove 34.

[0018] The limiting groove 34 has a trapezoidal cross-section. The limiting protrusion 11 has an arc-shaped cross-section.

[0019] The door ring assembly also includes a mounting base 40, through which the rotating shaft 31 is mounted between the upper door ring 21 and the lower door ring 22. The mounting base 40 includes an upper seat 42, a lower seat 43, and a connecting plate 44. The upper and lower ends of the connecting plate 44 are connected to the upper seat 42 and the lower seat 43 respectively. Both the upper seat 42 and the lower seat 43 are provided with shaft holes 45, and the upper and lower ends of the rotating shaft 31 are rotatably disposed within the corresponding shaft holes 45. During assembly, the upper seat 42 and the lower seat 43 are first connected as a single unit via the connecting plate 44. Then, the lower limit wheel 33, the guide wheel 32, and the upper limit wheel 33 are stacked on top of each other and inserted between the upper seat 42 and the lower seat 43. Finally, the rotating shaft 31 is inserted from top to bottom into the shaft holes of the upper seat, the upper limit wheel 33, the guide wheel 32, the lower limit wheel 33, and the lower seat shaft hole. After assembly, the mounting base 40 is fixed between the upper door ring 21 and the lower door ring 22, simplifying the installation operation.

[0020] The outer walls of the limiting wheel 33 and the guide wheel 32 are provided with a rubber layer. This prevents the limiting protrusion 11 from directly contacting the limiting wheel 33 and the shuttle 10 from directly contacting the guide wheel 32, thus avoiding wear and improving the product's service life.
