Description

Technical Field

[0001] The utility model relates to the technical field of spindle slide rail discs of braiding machines, and in particular to a spindle rail disc of a braiding machine. Background Art

[0002] A braiding machine is a mechanical device that interweaves warp and weft threads or multiple strands of wire to create various woven fabrics. It is widely used in industry and daily life. One of the key components of a braiding machine is the spindle slide. This slide supports the spindle and controls its movement along a predetermined trajectory, ensuring precision and efficiency during the weaving process.

[0003] The design and quality of the spindle track disc directly impacts the performance and product quality of the braiding machine. Existing spindle track discs for braiding machines typically achieve spindle trajectory control by cutting the spindle track directly into the disc. However, this manufacturing method has significant drawbacks. Frequent contact between the spindle and the track during high-speed operation can lead to severe wear on the track surface. This wear increases over time, impacting the normal operation of the braiding machine.

[0004] Rail wear not only reduces production efficiency but can also lead to unstable product quality. When rail wear reaches a certain level, users often need to replace the entire spindle slide, which significantly increases maintenance costs and equipment downtime, significantly increasing the cost of use. Utility Model Content

[0005] The utility model provides a spindle rail disc for a braiding machine, which solves the problem in the related art that when the rail is worn to a certain extent, the entire spindle slide rail disc needs to be replaced, which greatly increases maintenance costs and equipment downtime.

[0006] The technical solution of the utility model is as follows:

[0007] A spindle track disk for a braiding machine comprises a disk body, wherein the disk body comprises a plurality of slide rail disks circumferentially arranged around the disk body and a plurality of two connecting guide blocks located between two adjacent slide rail disks, wherein the slide rail disks and the connecting guide blocks are both detachably connected to the disk body, an arc-shaped spindle track is provided in the slide rail disk, the two connecting guide blocks and the two slide rail disks on both sides thereof form an X-shaped spindle track, and the two adjacent arc-shaped spindle tracks and the X-shaped spindle track located therein form an 8-shaped spindle track, and the slide rail disk comprises an inner ring structure and an outer ring structure, wherein the inner ring structure and the outer ring structure are both detachably connected to the disk body.

[0008] Furthermore, the inner ring structure is a guide ring, which is detachably connected to the disk body, and the arc-shaped spindle track is located on the side of the guide ring away from the center of the slide disk where it is located, and the side of the guide ring away from the center of the slide disk where it is located is the inner wall of the arc-shaped spindle track.

[0009] Furthermore, the outer ring structure includes a first outer arc ring and a second outer arc ring, and the first outer arc ring and the second outer arc ring are both detachably connected to the disk body, and the ends on the same side of the first outer arc ring and the second outer arc ring are respectively abutted against two connecting guide blocks on the same side of the slide rail disk where they are located, and the arc spindle track is located on the side of the first outer arc ring and the second outer arc ring facing the center of the slide rail disk where they are located, and the side of the first outer arc ring and the second outer arc ring facing the center of the slide rail disk where they are located is the outer side wall of the arc spindle track.

[0010] Furthermore, the connecting guide block, guide ring, first outer arc ring, and second outer arc ring are all provided with screw holes and pin holes, and corresponding bolts or pins are connected in the screw holes and pin holes. The connecting guide block, guide ring, first outer arc ring, and second outer arc ring are detachably connected to the disk body by embedding pins into the screw holes or pin holes.

[0011] Furthermore, the connecting guide block has a fan-shaped structure.

[0012] Furthermore, the slide plate and the connecting guide block both include a high hardness layer, a shock absorbing layer, and a support layer. The shock absorbing layer is located between the high hardness layer and the support layer, and the shock absorbing layer is fixedly connected to the high hardness layer and the support layer.

[0014] The working principle and beneficial effects of the utility model are as follows:

[0015] The modular structure of the slideway disc and connecting guide blocks in this utility model allows for individual replacement of worn track sections, rather than replacing the entire spindle track disc. When the curved or X-shaped spindle track wears, only the corresponding inner or outer ring structure or connecting guide blocks can be replaced. This detachable, modular design significantly reduces replacement costs, and because only worn sections need to be replaced, equipment downtime is significantly reduced. This design effectively addresses the maintenance challenges and cost issues inherent in existing technologies. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] like Figures 1 to 3 As shown, Example 1 proposes a spindle track disk for a braiding machine, comprising a disk body 1, wherein the disk body 1 comprises a plurality of slide disks 2 circumferentially arranged around the disk body 1 and two connecting guide blocks 3 located between two adjacent slide disks 2, the slide disks 2 and the connecting guide blocks 3 are both detachably connected to the disk body 1, an arc-shaped spindle track 24 is arranged in the slide disk 2, the two connecting guide blocks 3 and the two slide disks 2 on both sides thereof form an X-shaped spindle track 31, the two adjacent arc-shaped spindle tracks 24 and the X-shaped spindle track 31 located therein form an 8-shaped spindle track, the slide disk 2 comprises an inner ring structure and an outer ring structure, both the inner ring structure and the outer ring structure are detachably connected to the disk body 1, and the connecting guide blocks 3 are fan-shaped structures.

[0025] The disc body 1 is the foundational structure of the entire spindle track disc, used to support and connect the various track discs and the connecting guide block 3. The slide track disc 2 is a component used to carry the spindle and guide it along a predetermined trajectory. It is internally equipped with a curved spindle track 24; this curved spindle track 24 allows the spindle to move smoothly along the track, reducing friction and resistance during operation. The modular design of the slide track disc 2 also allows for replacement of a single slide track disc 2 when the curved track wears out, rather than replacing the entire disc body 1, reducing maintenance costs. The connecting guide block 3 and the slide plate 2 form an X-shaped spindle track 31, which is mainly used to connect adjacent slide plates 2 and provide transition guidance. The design of the connecting guide block 3 enables the arc-shaped spindle track 24 of the slide plate 2 to transition smoothly, forming a continuous 8-shaped spindle track; the X-shaped spindle track 31 not only provides a transition guidance function, but also helps maintain the stable operation of the spindle, improving the overall operation stability. The modular design of the connecting guide block 3 also supports replacement and maintenance, reducing interference with the entire disk body 1; at the same time, the design of the connecting guide block 3 divides the complex track shape into a simple fan-shaped structure, which greatly reduces the difficulty of processing. The processing accuracy of the fan-shaped shape is easy to control, and the production efficiency can be improved through modular production methods.

[0026] In Example 1, the inner ring structure is a guide ring 21, which is detachably connected to the disk body 1. The arc-shaped spindle track 24 is located on the side of the guide ring 21 away from the center of the slide rail disk 2 where it is located. The side of the guide ring 21 away from the center of the slide rail disk 2 where it is located is the inner wall of the arc-shaped spindle track 24.

[0027] The guide ring 21 forms the inner ring structure of the slide plate 2, provides the basic structure of the arc-shaped spindle track 24, and is responsible for the inner support and guiding function of the spindle track. The design of the guide ring 21 ensures that the spindle always remains within the predetermined track during operation, effectively preventing the spindle from deviating from the track and improving the weaving accuracy. As the inner wall of the spindle track, the guide ring 21 increases the rigidity and stability of the overall structure, resisting external pressure and vibration. The detachable design of the guide ring 21 makes maintenance and replacement more efficient. If the guide ring 21 part of the arc-shaped spindle track 24 is worn or damaged, only the guide ring 21 part needs to be replaced without replacing the entire slide plate 2, thereby reducing maintenance costs and shortening downtime.

[0028] In Example 1, the outer ring structure includes a first outer arc ring 22 and a second outer arc ring 23, and the first outer arc ring 22 and the second outer arc ring 23 are both detachably connected to the disk body 1. The ends on the same side of the first outer arc ring 22 and the second outer arc ring 23 are respectively abutted against the two connecting guide blocks 3 on the same side of the slide rail disk 2 where they are located, and the arc spindle track 24 is located on the side of the first outer arc ring 22 and the second outer arc ring 23 facing the center of the slide rail disk 2 where they are located, and the side of the first outer arc ring 22 and the second outer arc ring 23 facing the center of the slide rail disk 2 where they are located is the outer side wall of the arc spindle track 24.

[0029] The outer ring structure, as the outer part of the slide rail disc 2, provides additional support and stability, and at the same time forms the outer side wall of the arc-shaped spindle track 24. The outer ring structure improves the strength and rigidity of the entire spindle track disc, and can better withstand the load during operation. The detachable design makes it easy to remove the outer ring when replacement or maintenance is required, reducing the complexity of maintenance. The end on the same side of the first outer arc ring 22 and the second outer arc ring 23 abuts the connecting guide block 3 on the same side of the slide rail disc 2 where they are located, providing support and connection for the arc-shaped spindle track 24. By abutting against the connecting guide block 3, the first outer arc ring 22 and the second outer arc ring 23 ensure the precise alignment between the slide rail disc 2 and the connecting guide block 3, thereby improving the stability of the overall structure.

[0030] In Example 1, the connecting guide block 3, the guide ring 21, the first outer arc ring 22, and the second outer arc ring 23 are all provided with screw holes 4 and pin holes 5, and the screw holes 4 and the pin holes 5 are connected with corresponding bolts or pins. The connecting guide block 3, the guide ring 21, the first outer arc ring 22, and the second outer arc ring 23 are detachably connected to the disk body 1 by pins embedded in the screw holes 4 or the pin holes 5.

[0031] Screw holes 4 and pin holes 5 are used to secure the guide block 3, guide ring 21, first outer arcuate ring 22, and second outer arcuate ring 23 to the disc body 1. The bolt and pin connection allows for fine-tuning during assembly, ensuring precise alignment and a secure connection between the various components. This bolt and pin connection design facilitates disassembly and replacement of the various components, improving maintenance efficiency.

[0032] Example 2

[0033] like Figure 4As shown, in Example 2, based on Example 1, the slide rail plate 2 and the connecting guide block 3 both include a high hardness layer 100, a shock-absorbing layer 200, and a support layer 300. The shock-absorbing layer 200 is located between the high hardness layer 100 and the support layer 300. The shock-absorbing layer 200 is fixedly connected to the high hardness layer 100 and the support layer 300. The high hardness layer 100 is made of 45 steel or wear-resistant powder alloy material, the shock-absorbing layer 200 is made of thermoplastic polyurethane elastomer material, and the support layer 300 is made of 450 ductile iron material.

[0034] The high-hardness layer 100 is primarily responsible for providing the spindle track disk with hardness and wear resistance. It provides a solid surface for the slide track disk 2 and the track portion connecting the guide block 3, ensuring effective spindle guidance during operation and reducing wear. The high-hardness layer 100 ensures the smoothness and stability of the spindle track, improving the overall operating accuracy and efficiency of the braiding machine. 45 steel is a high-quality carbon structural steel with high strength, good machinability, heat treatability, toughness, and low cost, making it suitable for manufacturing components that withstand medium loads. Wear-resistant powder alloys have extremely high hardness and wear resistance, which can significantly improve the wear resistance of the high-hardness layer 100 and extend its service life in high-friction or high-wear environments. At the same time, wear-resistant powder alloys can also significantly improve the wear resistance, fatigue resistance, corrosion resistance, and high-temperature resistance of the high-hardness layer 100. Using 45 steel or wear-resistant powder alloys in the high-hardness layer 100 ensures the wear resistance and precision of the spindle track, adapting to high-load working environments. The shock-absorbing layer 200 is located between the high-hardness layer 100 and the support layer 300 and is used to absorb and mitigate vibrations and impacts during the operation of the braiding machine. This reduces the transmission of vibrations to the mechanical components and protects the high-hardness layer 100 and the support layer 300. The shock-absorbing layer 200 helps reduce noise during mechanical operation, improves the comfort of the operating environment, reduces the impact of vibrations on the work environment and operators, and improves overall work comfort. Thermoplastic polyurethane elastomers have excellent elasticity and cushioning properties, effectively absorbing vibrations and impacts, reducing the burden on mechanical components. The use of TPU in the shock-absorbing layer 200 effectively reduces shock and absorbs impacts, improving the stability and comfort of the entire disc body 1. The support layer 300 provides overall structural strength and support, ensuring the stability of the high-hardness layer 100 and the shock-absorbing layer 200. It withstands loads from all directions and ensures a stable connection between the layers. 450 ductile iron is a ductile iron with a strength of 450 MPa. It combines high strength, ductility, and properties such as wear resistance, impact resistance, and corrosion resistance. The spherical graphite in the ductile iron has a good vibration absorption effect. 450 ductile iron can effectively reduce vibration during mechanical operation. Using 450 ductile iron in the support layer 300 can provide sufficient support strength and optimize mechanical properties.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
