Abstract
Description
Technical Field
[0001] This utility model relates to the field of circular loom technology, and more specifically, to a rotating 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 rotating track structure for a suspended circular loom.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A rotating shaft track structure for a suspended circular loom includes a shuttle and a track for the shuttle to slide on. The track includes an upper gate ring and a lower gate ring arranged opposite each other. A plurality of rotating shafts are rotatably arranged between the upper gate ring and the lower gate ring. An upper support truncated cone and a lower support truncated cone are respectively provided at the upper and lower ends of the rotating shafts. The upper support truncated cone and the lower support truncated cone are arranged symmetrically.
[0007] The shuttle has an upper mating surface and a lower mating surface on the side facing the rotating shaft. The upper mating surface mates with the upper conical surface of the upper supporting frustum, and the lower mating surface mates with the lower conical surface of the lower supporting frustum.
[0008] The upper and lower mating surfaces of the shuttle slide on the upper and lower conical surfaces respectively, causing the shuttle to make a circular motion between the upper and lower gate rings.
[0009] The present invention is further provided that the bottom surface of the upper supporting frustum and the bottom surface of the lower supporting frustum are both located on the inner side or both located on the outer side.
[0010] The present invention further includes: a limiting groove is provided between the upper supporting frustum and the lower supporting frustum, and a limiting flange that is adapted to the limiting groove is provided on the inner side of the shuttle.
[0011] The present invention is further provided with a heat dissipation groove on the limiting flange.
[0012] The present invention further includes the following features: the upper supporting frustum, the lower supporting frustum, and the limiting groove are all provided with wear-resistant layers.
[0013] The present invention is further provided that the upper support frustum and the lower support frustum are integrally formed with the rotating shaft.
[0014] The present invention is further provided that the upper support frustum and the lower support frustum are separately provided from the rotating shaft, wherein the upper support frustum and the lower support frustum are respectively installed on the upper end and the lower end of the rotating shaft through mounting holes.
[0015] The present invention further comprises: the rotating shaft being mounted between the upper door ring and the lower door ring via a mounting base;
[0016] Both ends of the mounting base are provided with bushings, and both ends of the rotating shaft are rotatably mounted on the corresponding bushings via bearings.
[0017] The present invention is further provided with: wire separators are provided on the left and right sides of the mounting base, wherein the mounting base and the wire separators on the left and right sides together form a cavity for mounting the rotating shaft.
[0018] The beneficial effects of this utility model are as follows: The circular loom has several rotating shafts rotatably arranged between the upper and lower gate rings. Each rotating shaft has an upper supporting truncated cone and a lower supporting truncated cone at its upper and lower ends, respectively, arranged symmetrically. The shuttle has an upper mating surface and a lower mating surface on the side facing the rotating shaft. The upper mating surface mates with the upper conical surface of the upper supporting truncated cone, and the lower mating surface mates with the lower conical surface of the lower supporting truncated cone. During the circular motion of the shuttle, the upper and lower mating surfaces slide on the upper and lower conical surfaces, respectively. The upper conical surface mates with the upper mating surface, and the lower conical surface mates with the lower mating surface, mutually pressing against the shuttle's mating surfaces in the axial direction to limit the shuttle's axial displacement, thereby improving the stability of the shuttle's operation and ensuring the weaving quality of the circular loom. This utility model uses symmetrically arranged upper and lower supporting truncated cones on the rotating shafts to limit the shuttle's axial displacement, replacing the traditional method of requiring two additional upper and lower rollers on the shuttle. This results in a simpler structure and easier installation. Attached Figure Description

[0027] See attached document Figures 1 to 7 The present invention provides a more detailed description of the rotating track structure of a suspended circular loom.
[0028] A rotating shaft track structure for a suspended circular loom includes a shuttle 3 and a track for the shuttle to slide on. The track includes an upper door ring 1 and a lower door ring 2 arranged opposite to each other. A plurality of rotating shafts 4 are rotatably arranged between the upper door ring 1 and the lower door ring 2. An upper support frustum 41 and a lower support frustum 42 are respectively provided at the upper and lower ends of the rotating shafts 4. The upper support frustum 41 and the lower support frustum 42 are symmetrically arranged.
[0029] The shuttle 3 is provided with an upper mating surface 31 and a lower mating surface 32 on the side facing the rotating shaft. The upper mating surface 31 mates with the upper conical surface 411 of the upper supporting frustum 41, and the lower mating surface 32 mates with the lower conical surface 421 of the lower supporting frustum 42.
[0030] During the circular motion of the shuttle 3, the upper mating surface 31 and the lower mating surface 32 slide on the upper conical surface 411 and the lower conical surface 421, respectively. The upper conical surface 411 engages with the upper mating surface 31, and the lower conical surface 421 engages with the lower mating surface 32. They press against each other in the axial direction to limit the axial displacement of the shuttle 3, improve the stability of the shuttle 3's operation, and ensure the weaving quality of the circular loom. This utility model uses an upper support frustum 41 and a lower support frustum 42 symmetrically arranged on the rotating shaft 4 to limit the axial displacement of the shuttle 3, replacing the traditional method of setting two additional upper and lower rollers on the shuttle 3. The structure is simpler and the installation is more convenient.
[0031] The bottom surfaces of the upper supporting frustum 41 and the lower supporting frustum 42 are both located on the inner side (as shown in the attached figure). Figure 1 Appendix Figure 3 and attached Figure 6 (as shown) or simultaneously located on the outside (as shown in the attached image) Figure 2 Appendix Figure 4 and attached Figure 5 As shown, the upper conical surface 411 and the lower conical surface 421 squeeze the shuttle 3 from two directions, thereby preventing the shuttle 3 from swinging up and down.
[0032] A limiting groove 43 is provided between the upper supporting frustum 41 and the lower supporting frustum 42. The inner side of the shuttle 3 is provided with a limiting flange 33 that is adapted to the limiting groove 43. When the shuttle 3 moves circumferentially within the gate ring, the limiting flange 33 rotates along the limiting groove 43. The limiting flange 33 always cooperates with the limiting groove 43, further restricting the shuttle 3 from swinging up and down relative to the rotating shaft 4, thereby improving the stability of the circular loom. A heat dissipation groove is provided on the limiting flange 33, so that there is a gap between the limiting flange 33 and the rotating shaft 4, allowing the heat generated by friction between the limiting flange 33 and the rotating shaft 4 to be dissipated in time.
[0033] The upper support frustum 41, the lower support frustum 42, and the limiting groove 43 are all provided with a wear-resistant layer 5, which is made of rubber or polyurethane, etc.; to reduce the friction between the shuttle 3 and the shaft 4 and reduce the wear of the shuttle 3 and the shaft 4.
[0034] The upper support frustum 41 and the lower support frustum 42 are integrally formed with the rotating shaft 4, so that the upper support frustum 41 and the lower support frustum 42 always rotate concentrically with the rotating shaft 4.
[0035] The upper support frustum 41 and the lower support frustum 42 can also be separately arranged from the rotating shaft 4, wherein the upper support frustum 41 and the lower support frustum 42 are respectively installed on the upper end and the lower end of the rotating shaft 4 through mounting holes; this facilitates the production and processing of the upper support frustum 41, the lower support frustum 42 and the rotating shaft 4.
[0036] The rotating shaft 4 is installed between the upper door ring 1 and the lower door ring 2 via a mounting base 6. Both ends of the mounting base 6 are provided with bushings 61, and both ends of the rotating shaft 4 are rotatably mounted on the corresponding bushings 61 via bearings 62. The mounting base 6 is fixedly installed between the upper door ring 1 and the lower door ring 2 by fastening screws. When the rotating shaft 4 needs maintenance, the mounting base 6 can be directly removed from the door ring for maintenance, making disassembly and assembly convenient.
[0037] The mounting base 6 is provided with a wire separator plate 62 on the left and right sides, and the mounting base 6 and the wire separator plates 62 on the left and right sides together form a cavity for mounting the rotating shaft 4; the rotating shaft 4 is placed in the cavity, and the wire separator plate 62 separates the weft wire and the rotating shaft 4 to prevent the weft wire from being wrapped by the rotating shaft 4.
[0038] 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.
