Description

Technical Field

[0001] This utility model relates to the field of bow-shaped plates, and more particularly to a bow-shaped plate for a textile combing machine. Background Technology

[0002] As consumers' demands for textile quality continue to rise, the combing process plays an increasingly crucial role in removing impurities and short, coarse fibers from cotton, wool, and silk fibers. Combed fabrics are significantly superior to carded fabrics in terms of texture, durability, and appearance, and are widely used in the production of high-end textiles.

[0003] In existing technology, the arc-shaped plate of a textile combing machine is a key component of the cylinder, often forming a combing unit together with combing needles. For example, some combing machine cylinders consist of a smooth, arc-shaped arc-shaped plate and a grooved arc-shaped needle plate seat, used to comb the cotton fiber bundles held by the nipper plate. Its working principle is that, with the cylinder rotating at a non-uniform speed, the surface-mounted combing needles move rapidly during combing and slowly during pulling, achieving parallel straightening and separation of the fibers through the coordinated movement of the nipper plate and the separating rollers.

[0004] However, existing comb plates have many drawbacks. On the one hand, the comb needles are mostly fixed, making it difficult to meet the diverse needs of different textiles for comb needle length and density. Furthermore, replacing the comb plate is a complex process, undoubtedly increasing production changeover and time costs. On the other hand, after prolonged use, it is difficult to flexibly address comb needle wear; replacing the entire comb plate would easily lead to resource waste and negatively impact combing efficiency and textile quality.

[0005] Therefore, this application provides a bow-shaped plate for a textile combing machine to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a bow-shaped plate for a textile combing machine, which has a simple structure and more flexible adaptation.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A bow-shaped plate for a textile combing machine includes a mounting base. Several mounting screws are threaded to both sides of the mounting base. An arc-shaped base is fixedly provided on the outside of the mounting screws. Four locking blocks are slidably provided on the upper end of the arc-shaped base. A needle plate is slidably provided on the upper end of each of the four locking blocks. A first needle tooth, a second needle tooth, and a third needle tooth are respectively provided on the upper end of each needle plate.

[0009] Furthermore, an installation ring is fixedly installed inside the arc-shaped base.

[0010] Furthermore, several second weight-reducing grooves are provided at both ends of the arc-shaped base.

[0011] Furthermore, mounting plates are fixedly provided at both ends of the mounting base.

[0012] Furthermore, an mounting layer is fixedly provided on the upper end of the needle plate.

[0013] Furthermore, an anti-slip layer is fixedly provided on the upper end of the mounting layer.

[0014] Furthermore, two first weight-reducing grooves are fixedly provided at both ends of the four needle plates.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model proposes a bow-shaped plate for a textile combing machine, featuring multiple weight-reducing grooves on its side. These grooves effectively reduce the weight of the bow-shaped plate itself, thereby lowering the rotational load during combing machine operation, reducing power loss, and contributing to more energy-efficient and high-performance operation. Furthermore, the weight-reducing grooves optimize the structural mechanical distribution of the bow-shaped plate, ensuring its strength while improving operational flexibility, reducing vibrations caused by inertia, and making fiber combing more stable. Simultaneously, the weight-reducing grooves also aid in heat dissipation, delaying component aging, and thus extending the service life of the equipment.

[0017] 2. This utility model proposes a bow-shaped plate for a textile combing machine, employing a locking block fixing method to accommodate replaceable needle plates of different densities. Users can quickly replace needles of different densities in different parts of the machine according to different textile raw materials and process requirements, without replacing the entire equipment. This allows for flexible adaptation to diverse production scenarios and improves the equipment's versatility. Furthermore, the locking block fixing method facilitates easy assembly and disassembly, reducing the difficulty and time cost of needle plate replacement. When a section of the needle plate shows wear, it can be replaced individually, reducing resource waste while consistently maintaining combing quality. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 2 , Figure 3 One embodiment provided by this utility model:

[0026] A bow-shaped plate for a textile combing machine includes a mounting base 2. Several mounting screws 4 are threaded to both sides of the mounting base 2. An arc-shaped base 5 is fixedly installed on the outside of the mounting screws 4. Four locking blocks 11 are slidably installed on the upper end of the arc-shaped base 5. A needle plate 12 is slidably installed on the upper end of the four locking blocks 11 respectively. A first needle tooth 6, a second needle tooth 7, and a third needle tooth 8 are respectively provided on the upper end of the needle plate 12. A mounting ring 3 is fixedly installed inside the arc-shaped base 5. Mounting plates 1 are fixedly installed at both ends of the mounting base 2. Two first weight reduction grooves 9 are fixedly installed at both ends of the four needle plates 12.

[0027] Specifically, the mounting base 2 is integrally formed from high-strength aluminum alloy. The threaded holes on both sides are compatible with the mounting screws 4. The mounting base 2 is secured to the combing machine frame using M8×30mm mounting screws 4 (performance grade 8.8), with a tightening torque of 15-18 N·m. The arc-shaped base 5 has an arc-shaped structure, matching the rotation trajectory of the combing machine's bow-shaped plate. Its internal mounting ring 3 is made of 6061-T6 aluminum alloy and is connected to the arc-shaped base 5 via a tenon and mortise structure and bolts (M4×10mm stainless steel bolts, pre-tightening torque 3 N·m). This reinforces the structural strength of the arc-shaped base 5, ensuring the stability of the bow-shaped plate during high-speed operation. Mounting plates 1 are located at both ends of the mounting base 2. The mounting plates 1 are fixed to the combing machine frame with bolts, limiting the lateral displacement of the locking block 11 and the needle plate 12, facilitating precise installation and positioning with other components of the combing machine. The four needle plates 12 correspond to different combing functional areas. The first weight-reducing grooves 9 at both ends of each needle plate 12 adopt a hollow design, which reduces the weight of the needle plate 12 and optimizes the stress distribution of the needle plate 12, avoiding deformation caused by local stress concentration. The needle plate 12 is slidably connected to the arc-shaped base 5 through the locking block 11. The gap between the locking block 11 and the guide rail of the arc-shaped base 5 is ≤0.1mm, ensuring that the needle plate 12 slides smoothly without shaking. The bottom of the locking block 11 has an I-shaped groove structure, which cooperates with the guide rail at the top of the arc-shaped base 5, and can slide and adjust its position along the guide rail direction. The upper end of the I-shaped locking block 11 is used to lock the concave structure at the bottom of the needle plate 12, realizing the quick installation and removal of the needle plate 12. The first tooth 6 (density 12 teeth / cm) is the inlet section, the second tooth 7 (density 18 teeth / cm) is the working section, and the third tooth 8 (density 24 teeth / cm) is the outlet section. The tooth pitch tolerance is ±0.05mm. The inlet section guides the fibers to enter smoothly, the working section has a standard combing angle, and the outlet section reduces fiber dragging.

[0028] Reference Figure 3 Several second weight-reducing grooves 10 are provided at both ends of the arc-shaped base 5.

[0029] Specifically, the several second weight-reducing grooves 10 set at both ends of the arc-shaped base 5 are fan-shaped hollow structures (radius 20mm, central angle 60°), with a groove wall thickness ≥2mm. This not only further reduces the overall weight of the arc-shaped plate but also effectively reduces the inertia during operation. These weight-reducing grooves were designed using mechanical simulation analysis to ensure that the strength and rigidity of the arc-shaped base 5 can still be guaranteed while reducing material, meeting the requirements of high-speed operation of the combing machine.

[0030] Reference Figure 4 An installation layer 13 is fixedly provided on the upper end of the needle plate 12, and an anti-slip layer 14 is fixedly provided on the upper end of the installation layer 13.

[0031] Specifically, the mounting layer 13 at the upper end of the needle plate 12 is made of wear-resistant engineering plastic and is integrally molded with the needle plate 12 through injection molding, providing a stable mounting base for the needle teeth. The anti-slip layer 14 at the upper end of the mounting layer 13 is made of thermoplastic elastomer (TPE) material, with a surface grid pattern depth of 0.3mm, a width of 0.2mm, and a friction coefficient ≥0.8, which increases the friction with the needle teeth, prevents the needle teeth from loosening or shifting during the combing process, and ensures the stability of the combing effect.

[0032] Working Principle: In use, the bow-shaped plate is first installed into the corresponding position on the combing machine using the mounting plate 1. The mounting base 2 is then securely connected to the combing machine frame using the mounting screws 4. When it is necessary to replace the needle plates 12 with different densities, simply move the mounting plate 1, push the locking block 11 to slide along the guide rail of the arc-shaped base 5, and remove the worn or replaceable needle plate 12. Then, insert the suitable needle plate 12 into the slot of the locking block 11 and adjust it to the appropriate position. During the operation of the combing machine, the bow-shaped plate rotates non-uniformly with the cylinder. When the bow-shaped plate enters the combing stage, the first needle tooth 6, the second needle tooth 7, and the third needle tooth 8 on the needle plate 12 sequentially comb the cotton fiber bundles held by the clamping plate, separating short fibers, impurities, etc. Because the needle plate 12 adopts a replaceable design, needle plates with different needle tooth densities and arrangements can be replaced according to different raw material characteristics and product requirements to achieve the best combing effect. The weight-reducing grooves on the arc-shaped base 5 and the needle plate 12 effectively reduce the rotational inertia of the arc-shaped plate, making the cylinder more flexible during start-up, acceleration, and deceleration, and reducing power loss. At the same time, the mounting layer 13 and the anti-slip layer 14 ensure that the needle teeth remain stable under high-speed operation, avoiding the impact of loose needle teeth on combing quality, thereby ensuring the efficient and stable operation of the combing machine.

[0033] In practical production applications, the replacement strategy for the needle plate 12 is further refined for different textile raw materials. When processing cotton fibers, if producing high-end pure cotton fabrics, the requirements for fiber combing are extremely high. A needle plate 12 with a density of 10 teeth / cm for the first needle tooth 6 in the inlet section can be selected. Its sparser teeth can better guide the cotton fibers into the combing area, reducing fiber damage. The density of the second needle tooth 7 in the working section is 20 teeth / cm, increasing combing intensity and effectively removing cotton knots and impurities. The density of the third needle tooth 8 in the outlet section is 26 teeth / cm, further optimizing fiber arrangement and improving yarn quality. For hemp fibers, due to their coarseness and stiffness, a needle plate 12 with a density of 14 teeth / cm for the first needle tooth 6 in the inlet section can be selected to enhance the gripping force on the hemp fibers. The second needle tooth 7 in the working section adopts a special comb needle shape and angle design with a density of 16 teeth / cm, which is more suitable for the combing characteristics of hemp fibers and improves the combing effect. The density of the third needle tooth 8 in the outlet section is 22 teeth / cm, ensuring smooth fiber output and reducing fiber breakage. For chemical fibers, due to their smooth surface and easy sliding, the density of the first needle tooth 6 in the inlet section is 13 teeth / cm, which can effectively guide the fibers; the density of the second needle tooth 7 in the working section is 19 teeth / cm, which, together with an appropriate combing angle, improves the combing effect; the density of the third needle tooth 8 in the outlet section is 25 teeth / cm, and the needle teeth with a smooth surface treatment are used to reduce the friction between the fibers and the needle teeth and reduce the fiber dragging phenomenon.
