Description

Technical Field

[0001] The present application belongs to the technical field of glass fiber production equipment, and specifically relates to a wear-resistant wire-laying shuttle and a composite shuttle body thereof. Background Art

[0002] The wire arrangement mechanism of the direct yarn drawing machine is the core component of the wire drawing machine, especially the grooved drum (cam) has a direct impact on the yarn ball forming. Since the glass fiber direct yarn drawing and winding yarn relies on the shuttle to arrange the wires back and forth, the reciprocating motion of the shuttle depends on the positive and negative double spiral grooves on the grooved drum. The positive and negative double spiral grooves push the shuttle as the grooved drum rotates. Under the guidance of the guide plate, the shuttle reciprocates at a high frequency in the positive and negative double spiral grooves of the grooved drum to achieve linear reciprocating wire arrangement motion. However, this type of grooved drum double spiral groove wire arrangement has two fatal defects: one is that the service life of the shuttle is too short, the reversing points of the double spiral grooves of the grooved drum at both ends are easily impacted and worn, the machine needs to be shut down to replace the shuttle frequently, and the speed cannot be increased, so it cannot meet the high linear speed wire drawing process; the second is material and processing. Since the multi-point drawing process is basically adopted for wire drawing, the grooved drum must also meet the multi-point drawing process, so the grooved drum will be longer. In order to increase its own rigidity and wear resistance, the long grooved drum is usually processed and hardened in an integral form, but the overall processing is prone to deformation and the deformation is greater after hardening, which is difficult to control. There are also contradictions in material selection: since the double helical groove is suitable for milling, the inner groove is relatively small and prone to wear and chipping. However, the base material must also be resistant to strong corrosion, wear, and impact. Currently, to reduce shuttle consumption, reduce frequent shuttle downtime for replacement, and appropriately increase operating speed, fiber or resin fiber is added to the nylon shuttle material to increase wear resistance and extend shuttle life. However, while the shuttle's wear resistance is increased, its hardness is also increased, resulting in excessive impact and rapid wear at the reversing points of the spiral groove at both ends of the grooved drum.

[0016] Beneficial technical effects:

[0017] 1. This application adopts a composite shuttle body composed of a wear-resistant resin cover and a shuttle body, which can reduce the degree of wear between the shuttle body and the spacer, helping to extend the service life of the shuttle. At the same time, production maintenance can be carried out by simply replacing the composite resin cover, which helps to reduce production costs and maintenance costs.

By providing a thickened structure at the yarn guide opening or adopting a removable yarn guide nozzle, this application not only reduces the maintenance and overhaul difficulty of the yarn guide piece, but also helps reduce production and maintenance costs. Furthermore, the wear resistance of the yarn guide piece can be further increased by selecting a more wear-resistant and impact-resistant material for the yarn guide nozzle.

[0019] 3. Conventional methods typically extend the wear time of the wire guide opening by thickening the yarn guide piece. However, thickened and weighted yarn guide pieces have a large impulse, which can cause significant impact on mating components or areas on the drum during the shuttle's wire-traveling and reversing movements, making them susceptible to damage. The present invention utilizes a separately molded yarn guide mouth, allowing for a lightweight, flatter yarn guide piece. This lightweight yarn guide piece helps reduce the overall operating impulse of the shuttle, minimizing wear on the equipment and reducing power consumption.

The composite shuttle body made of a metal shuttle body and a resin wear-resistant resin cover is tightly matched, which can also avoid the occurrence of in-phase wear between the components, further reduce the degree of wear during equipment operation, and extend the service life of the equipment.

[0038] See also Figure 1-Figure 3 The wear-resistant wire arrangement shuttle disclosed in this application includes a slider 10, a spacer 20, a shuttle 30, and a yarn guide 40.

[0040] The spacer 20 is provided with a shuttle hole 210 and a blocking portion 220. The shuttle hole 210 passes through the spacer 20, and the blocking portion 220 is provided on the spacer 20 for assembling one end of the shuttle 20.

[0041] The sliding shuttle 30 includes a shuttle body 310 and a wear-resistant resin cover 320 , and the shuttle body 310 and the wear-resistant resin cover 320 are fixedly connected.

[0042] The shuttle body 310 is provided with a reciprocating drive part 3110 , a shuttle shaft 3120 , and a fastening structure 3130 ; the reciprocating drive part 3110 , the shuttle shaft 3120 , and the fastening structure 3130 are integrally formed, and the fastening structure 3130 is located between the reciprocating drive part 3110 and the shuttle shaft 3120 .

[0043] The wear-resistant resin cover 320 is provided with a shuttle shaft tight-fitting hole 3210 , a reversing drive portion 3220 , a spacer connecting portion 3230 , and a fastening fitting structure 3240 .

[0044] The shuttle shaft 3120 is fixedly disposed in the shuttle shaft tight-fitting hole 3210 , and the fastening structure 3130 is tightly fitted in the fastening fitting structure 3240 . The reciprocating drive portion 3110 extends out of the reversing drive portion 3220 .

[0045] The yarn guide plate 40 includes a square portion 440 and an arcuate portion 450, which are integrally formed. The square portion 440 is provided with an assembly hole 430, and the arcuate portion 450 is provided with a guide opening 410. A guide opening thickening structure 420 is provided at the opening of the guide opening 410. This thickening structure 420 is used to increase the wear resistance of the guide opening area. The yarn guide plate 40 is also provided with a weight-reducing structure 460.

[0046] The yarn guide piece 40 is fixedly assembled on the slider 10 through the cooperation of the assembly hole 430, the matching hole 140 and fasteners such as screws.

[0047] The spacer 20 is disposed in the spacer hole 120 on the slider 10 , and the blocking portion 220 on the spacer 20 extends out of the spacer hole 120 .

[0048] The spacer connecting portion 3230 on the wear-resistant resin cover 320 is disposed in the shuttle hole 210 on the spacer 20 , and the reciprocating driving portion 3110 and the reversing driving portion 3220 on the shuttle 30 extend out of the blocking portion 220 .

[0049] Principle and effect description:

[0050] The reciprocating drive unit 3110 and the reversing drive unit 3220 respectively drive the wire-traversing shuttle's reciprocating and reversing motions on the grooved drum. When the wire-traversing shuttle performs reciprocating and reversing motions on the grooved drum, relative motion occurs between the wear-resistant resin cover 320 and the spacer 20, preventing wear between the shuttle body 310 and the spacer 20. Furthermore, the thickened wire guide opening 420 at the wire guide opening 410 improves the wear resistance of the yarn guide 40.

[0051] Thus, because the wear resistance of the easily worn parts or areas of the cable traversing shuttle has been enhanced, the wear-resistant cable traversing shuttle provided by the present application has a longer service life. Furthermore, due to the enhanced wear resistance of the cable traversing shuttle, the wear-resistant cable traversing shuttle provided by the present application can also be adapted to the application requirements of some high-end products requiring high-speed cable traversing. Furthermore, when the shuttle 30 becomes severely worn and requires replacement, only the wear-resistant resin cover 320 needs to be replaced, without having to replace the shuttle body 310, which has relatively high material and processing costs. This also helps reduce maintenance and production costs.

[0052] Furthermore, the use of a tightly fitted metal shuttle body 310 and a wear-resistant resin cover 320 for the shuttle 30 prevents in-phase wear (wear between similar materials) between the shuttle 30 and the spacer 20, significantly reducing component wear. It is generally believed that similar friction coefficients between similar materials increase the likelihood of reaching higher temperatures and pressures during friction, leading to increased wear (increased adhesive wear).

[0053] When relative rotation occurs between the shuttle 30 and the spacer 20, the wear between the wear-resistant resin cover 320 made of resin material and the spacer 20 made of metal material is out-of-phase wear; therefore, the shuttle 30 formed by the shuttle body 310 made of metal material and the wear-resistant resin cover 320 made of resin material can also avoid the occurrence of in-phase wear between the components, further reduce the degree of wear during equipment operation, and extend the service life of the equipment.

[0054] In another embodiment of the present application, a yarn guide nozzle 470 is used to increase the wear resistance of the yarn guide piece 40. Figure 4-Figure 6 The wear-resistant thread-arranging shuttle also includes a separately formed yarn guide nozzle 470.

[0055] The opening of the yarn guide port 410 is provided with a locking groove 4110. The yarn guide nozzle 470 is provided with a yarn guide plate locking groove 4710 and a locking head 4720. The yarn guide nozzle 470 has a U-shaped structure, which provides a certain degree of structural flexibility. The yarn guide nozzle 470 is inserted into the yarn guide port 410, with both sides of the yarn guide port 410 tightly fitting into the yarn guide plate locking grooves. The locking head 4720 is then engaged with the locking groove 4110. This completes the assembly of the yarn guide nozzle 470 into the yarn guide port 410.

[0056] When the yarn guide nozzle 470 needs to be replaced due to wear and tear, it can be replaced by simply disassembling and installing it, without having to disassemble the entire yarn guide piece 40. This not only reduces the difficulty of maintenance and inspection, but also helps reduce production and maintenance costs. At the same time, the wear resistance of the yarn guide nozzle 470 can be further increased by selecting a more wear-resistant and impact-resistant material such as tungsten steel for the yarn guide nozzle 470.

[0057] Prior art methods typically extend the wear time of the wire guide opening by thickening the yarn guide piece. However, thickened and weighted yarn guide pieces have a large impulse, and when the shuttle moves through the wire and reverses, they also exert a large impact on the mating parts or parts on the groove drum, making them susceptible to damage. The present application utilizes a separately molded yarn guide mouth, allowing for a lightweight and flatter yarn guide piece. The lightweight yarn guide piece helps reduce the overall operating impulse of the shuttle, reducing equipment wear and power consumption.

[0058] The above describes the technical solution and technical effects of the present application in detail in combination with the drawings and specific embodiments of the specification. It should be noted that technicians in this field can also develop other embodiments on this basis; any simple deformation and equivalent substitution that does not deviate from the innovative concept of the present application are covered by the present application and fall within the scope of protection of this patent.
