Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile equipment, and more specifically to a shuttle suspension mechanism for a circular loom. Background Technology
[0002] Circular looms are used to weave tube fabric. The overall machine structure is circular, with warp yarns threaded through the top and bottom. The warp yarns cross each other through a frame, and the weft yarns are woven into tube fabric by the shuttle moving in a circular motion within these openings. Multiple shuttles are evenly arranged on a gate ring to perform circular motion, completing the weaving of multiple weft yarns. In existing technology, such as the applicant's previous utility model patent application (patent number 202020123913.2, entitled "A Plastic Circular Loom"), a ring of rollers on the gate ring supports the shuttle's movement, improving its smoothness. However, it still uses a traditional structure for shuttle positioning, with inner shuttle wheels supporting the shuttle on the gate ring at the top and bottom. This introduces complexity to the shuttle and gate ring structure, making disassembly and assembly cumbersome, and increasing the possibility of the inner shuttle wheels crushing the yarn during long-term operation or adjustment. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a shuttle suspension mechanism for a circular loom, which ensures the smooth and stable operation of the shuttle by providing structural support and limiting between the shuttle and the gate ring, while simplifying the shuttle structure.
[0004] This utility model provides the following technical solution: a shuttle suspension mechanism for a circular loom, including a gate assembly and several shuttles. Multiple support roller groups are arranged along the circumference on the gate assembly. Each support roller group includes a pair of support rollers symmetrically arranged on the gate assembly. An inclined support surface is provided on the outer side of the outer surface of the pair of support rollers. The outer side of the shuttle is configured as a first mating surface in the middle and second mating surfaces on both sides. The second mating surfaces are inclined mating surfaces extending obliquely outward from the first mating surfaces. When the shuttle is supported on the support roller group of the gate assembly and performs circular motion, the outer surfaces of the pair of support rollers are supported on the first mating surfaces, and the outer inclined support surfaces are supported on the second mating surfaces.
[0005] As an improvement, the door ring assembly includes an upper door ring, a lower door ring, and multiple rollers. The multiple rollers are arranged circumferentially between the upper and lower door rings, and each pair of support rollers is correspondingly arranged on the rollers for rotation.
[0006] As an improvement, multiple mounting grooves are evenly provided on the circumference of the upper and lower door rings, the two ends of the roller shaft are accommodated in the mounting grooves, and mounting roller shafts with rotatable mounting components are provided on the opposite outer sides of the upper and lower door rings.
[0007] As an improvement, a bearing is provided in the middle of the mounting component to cooperate with the roller shaft, and mounting holes are provided on both sides of the mounting component for fastener installation.
[0008] As an improvement, the mounting groove is located on the outer circumference of the upper and lower door rings.
[0009] The beneficial effects of this utility model are as follows: By combining a pair of support rollers with the outer inclined support surface and the two mating surfaces of the shuttle, a good support and limiting structure is formed. The shuttle can stably perform a suspended circular motion on the gate assembly under external drive to complete the weaving work. This simplifies the structure of the shuttle, reduces the cost of component manufacturing, and the structure of the shuttle and gate assembly mating is located on the outside, reducing the possibility of the internal yarn being crushed.

[0011] Figure 2 for Figure 1 Enlarged view of point A in the middle.
[0012] Figure 3 This is a cross-sectional view of the support roller assembly of this utility model. Detailed Implementation
[0013] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0014] like Figure 1 , 2 Figure 3 shows a specific embodiment of the shuttle suspension mechanism of the circular loom of this utility model. This embodiment includes a gate assembly 1 and several shuttles 2. Multiple support roller groups 3 are arranged along the circumference on the gate assembly 1. The support roller group 3 includes a pair of support rollers 31 symmetrically arranged on the gate assembly 1. The outer surface of the pair of support rollers 31 is provided with an inclined support surface 32. The outer surface of the shuttle 2 is provided with a first mating surface 21 in the middle and second mating surfaces 22 on both sides. The second mating surface 22 is an inclined mating surface that extends obliquely outward from the first mating surface 21. When the shuttle 2 is supported on the support roller group 3 of the gate assembly 1 and performs circular motion, the outer surface of the pair of support rollers 31 is supported on the first mating surface 21, and the outer inclined support surface 32 is supported on the second mating surface 22.
[0015] When using this utility model, such as Figure 1As shown, the gate assembly 1 is circular, horizontally positioned with its central axis vertically oriented. Multiple support roller groups 3 are evenly arranged on the inner circumference of the gate assembly 1 to form a circular track for the shuttle 2 to run on. The shuttle 2 is driven by an external power source, such as a motor, to perform circular motion and complete the weaving work of the circular loom. A pair of support rollers 31 are symmetrically positioned to provide stable support for the outer surface of the shuttle 2. The circumferentially arranged pairs of support rollers 31 form a stable circular inner running surface. The rotation of the support rollers 31 allows the shuttle 2 to run smoothly in a rolling state. As a simplification and optimization of the shuttle 2 structure, the original shuttle wheel of the shuttle 2 is eliminated, and consequently, the support structure of the gate assembly 1 itself that cooperates with the shuttle wheel is also eliminated. Simultaneously, to limit the relative vertical position of the gate assembly 1 and the support roller groups 3 with the shuttle 2, an inclined support surface 32 is provided on the outer side of a pair of support rollers 31. The corresponding outer surface of the shuttle 2 is configured as a first mating surface 21 in the middle and second mating surfaces 22 on both sides, as shown... Figure 3 As shown, when the support roller group 3 and the shuttle 2 support each other, the outer surfaces of the support rollers 31 on both sides support the first mating surface 21 to ensure radial support and stability, and the inclined support surfaces 32 on both sides support the second mating surface 22 to ensure axial support and stability. Thus, when the shuttle 2 runs around the circumference at high speed, it maintains a relatively stable position with the support roller group 3, avoiding swaying. Furthermore, while simplifying the component structure and reducing component costs, the support structure is located entirely outside the shuttle 2, avoiding yarn crushing and ensuring the weft yarn weaving quality.
[0016] As an improved specific implementation, the door ring assembly 1 includes an upper door ring 11, a lower door ring 12 and a plurality of rollers 13. The plurality of rollers 13 are arranged circumferentially between the upper door ring 11 and the lower door ring 12, and each pair of support rollers 31 is correspondingly arranged on the rollers 13 for rotation.
[0017] like Figure 1 , 2 As shown in Figure 3, the upper gate ring 11 and the lower gate ring 12 form a space to accommodate the support roller group 3 and the shuttle 2. Multiple roller shafts 13 are provided for the orderly installation of each pair of support rollers 31. The rotation of the roller shafts 13 synchronously drives the orderly rotation of each pair of support rollers 31, cooperating with the outer surface of the shuttle 2. Preferably, the roller shafts 13 can also be connected to an external power source, allowing selective driving of the roller shafts 13 to rotate actively, enabling the support rollers 31 to provide power for the circular motion of the shuttle 2, making the circular motion smoother.
[0018] As an improved specific implementation, multiple mounting grooves 14 are evenly arranged on the circumference of the upper door ring 11 and the lower door ring 12. The two ends of the roller shaft 13 are accommodated in the mounting grooves 14, and the mounting roller shaft 13 is rotatably mounted on the opposite outer side of the upper door ring 11 and the lower door ring 12.
[0019] like Figure 1 , 2 As shown in Figure 3, the two ends of the roller shaft 13 are installed from the mounting groove 14 on the side to the upper door ring 11 and the lower door ring 12. Then, the roller shaft 13 is limited by the mounting parts 15 on the upper and lower outer sides and the installation is completed. When it is necessary to replace a certain set of support roller group 3, convenient disassembly and assembly work can also be carried out on the upper and lower outer sides.
[0020] As an improved specific implementation, a bearing 16 is provided in the middle of the mounting part 15 to cooperate with the roller shaft 13, and mounting holes 17 are provided on both sides of the mounting part 15 for fastener installation.
[0021] like Figure 1 , 2 As shown in Figure 3, the bearing component 16, in conjunction with the mounting component 15, limits the two ends of the roller shaft 13 and allows for smooth rotation. Fasteners pass through the mounting holes 17 from the outside to stably install the mounting component 15 on the upper door ring 11 and the lower door ring 12. The space between the upper and lower parts is spacious, making disassembly and assembly convenient.
[0022] As an improved specific implementation, the mounting groove 14 is provided on the outer circumference of the upper door ring 11 and the lower door ring 12.
[0023] like Figure 2 As shown, preferably, the mounting groove 14 located on the outside allows maintenance personnel to easily remove the roller shaft 13 and the support roller group 3 on it after disassembling the fasteners at the upper and lower positions, and then replace it with a new roller shaft 13 and the support roller group 3 on it, thereby providing operational convenience for installation and maintenance.
[0024] The above are merely preferred embodiments 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 within its protection scope. 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 its protection scope.
