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 20202012391 3.2, 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 of the gate assembly. Each support roller group includes a pair of support rollers symmetrically arranged on the gate assembly. The outer surfaces of the pair of support rollers have inclined support outer surfaces, and the inner surfaces of the pair of support rollers have inclined support inner surfaces. The outer surface of the shuttle includes a first mating portion in the middle, second mating portions on both sides of the first mating portion, and a third mating portion on the outer side of the second mating portion. The first mating portion forms an inclined mating inner surface facing both sides, the second mating portion forms an arc-shaped surface, and the third mating portion forms an inclined mating outer surface facing inwards. When the shuttle moves in a circular motion supported on the support roller groups of the gate assembly, the outer surfaces of the pair of support rollers are supported by the second mating portions, the inner inclined support inner surfaces are supported by the first mating portions, and the outer inclined support outer surfaces are supported by the third mating portions.

[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 slots are located on the outer circumference of the upper and lower door rings.

[0009] As an improvement, a pair of support rollers are each set as two sub-rollers. The four sub-rollers have the same structure and are installed on the roller shaft in opposite directions. The inclined surfaces on one side of the four sub-rollers are arranged in sequence as the outer surface of the inclined support, the inner surface of the inclined support, the inner surface of the inclined support, and the outer surface of the inclined support.

[0010] The beneficial effects of this utility model are as follows: By combining a pair of support rollers with the outer and inner inclined support surfaces of the shuttle, a good multi-position 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 shuttle structure, reduces the cost of component manufacturing, and the structure of the shuttle and gate assembly is located on the outside, reducing the possibility of the internal yarn being crushed. Attached Figure Description

[0012] Figure 2 for Figure 1 Enlarged view of point A in the middle.

[0013] Figure 3 This is a cross-sectional view of the support roller assembly of this utility model. Detailed Implementation

[0014] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0015] like Figure 1 , 2Figure 3 shows a specific embodiment of the shuttle suspension mechanism of the circular loom of this utility model. This embodiment includes a door ring assembly 1 and several shuttles 2. The door ring assembly 1 is provided with multiple support roller groups 3 along the circumference. The support roller group 3 includes a pair of support rollers 31 symmetrically arranged on the door ring assembly 1. The outer surface of the pair of support rollers 31 is provided with an inclined support outer surface 32, and the inner surface of the pair of support rollers 31 is provided with an inclined support inner surface 33. The outer surface of the shuttle 2 includes a first mating part 21 in the middle, a second mating part 22 provided on both sides of the first mating part 21, and a third mating part 23 provided on the outer side of the second mating part 22. The first mating part 21 forms an inclined mating inner surface facing both sides, the second mating part 22 forms an arc-shaped surface, and the third mating part 23 forms an inclined mating outer surface facing inward. When the shuttle 2 is supported on the support roller group 3 of the door ring assembly 1 and performs circumferential motion, the outer surface of the pair of support rollers 31 is supported by the second mating part 22, the inner inclined support inner surface 33 is supported by the first mating part 21, and the outer inclined support outer surface 32 is supported by the third mating part 23.

[0016] When using this utility model, such as Figure 1 As shown, the gate ring assembly 1 is circular, horizontally arranged, and its central axis is vertically arranged. Multiple support roller groups 3 are evenly arranged on the inner circumference of the gate ring 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 to 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 cooperating with the shuttle wheel is also eliminated. Simultaneously, to limit the relative vertical position of the gate assembly 1 and the support roller group 3 with the shuttle 2, an inclined support outer surface 32 is provided on the outer side of the pair of support rollers 31, and an inclined support inner surface 33 is provided on the inner side. Correspondingly, the outer surface of the shuttle 2 is configured with a first mating part 21, a second mating part 22, and a third mating part 23 from the center to both sides, as shown below. Figure 3 As shown, when the support roller group 3 and the shuttle 2 are supported and cooperate, the outer surfaces of the two support rollers 31 are supported by the second cooperation part 22 to ensure radial support and stability. The outer surfaces 32 and inner surfaces 33 of the two symmetrical oblique supports form multiple structural support limits with the third cooperation part 23 and the first cooperation part 21 on both sides, thereby ensuring axial support and stability. The surface of the support roller 31 and the outer surface of the shuttle 2 are stably attached, so that the position of the shuttle 2 relative to the support roller group 3 is relatively stable when the shuttle 2 is running around the circumference at high speed, avoiding the occurrence of shaking. Thus, on the basis of simplifying the component structure and reducing the component cost, the support structure is located completely outside the shuttle 2, avoiding the occurrence of yarn crushing and ensuring the weft yarn weaving quality.

[0017] 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.

[0018] 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, which then supports and cooperates 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.

[0019] 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 with the mounting member 15 is arranged on the opposite outer side of the upper door ring 11 and the lower door ring 12.

[0020] 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, and then the roller shaft 13 is limited by the mounting parts 15 on the upper and lower outer sides to complete the installation; 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.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] like Figure 2As 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.

[0025] As an improved specific implementation, a pair of support rollers 31 are respectively configured as two sub-roller bodies 4. The four sub-roller bodies 4 have the same structure and are installed on the roller shaft 1 3 in opposite directions. Then, the inclined surfaces on one side of the four sub-roller bodies 4 are arranged in sequence as the outer surface 32 of the inclined support, the inner surface 33 of the inclined support, the inner surface 33 of the inclined support, and the outer surface 32 of the inclined support.

[0026] like Figure 2 , 3 As shown, as an optimization, a pair of support rollers 31 is implemented by four sub-rollers 4. Each sub-roller 4 has a flat outer circumferential surface and a sloping surface on one side. When two sub-rollers 4 are coaxially arranged in opposite directions, a structure with a central outer circumferential surface and sloping surfaces on both sides is formed. In this embodiment, the structure of a single support roller 31 is disassembled into two sub-rollers 4, making the manufacturing of a single sub-roller 4 more convenient. After disassembly, the axial length of a single sub-roller 4 is halved relative to a single support roller 31, making it easier to install and position the four sub-rollers 4 separately on the roller shaft 13. During installation, the four sub-rollers 4 are installed in opposite directions to form a sequential arrangement of the outer surface 32 of the inclined support, the inner surface 33 of the inclined support, the inner surface 33 of the inclined support, and the outer surface 32 of the inclined support.

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.
