Description

Technical Field

[0001] The utility model relates to the technical field of carding needle winding belts, and specifically relates to a textile carding needle winding belt structure. Background Art

[0002] In the field of textile machinery, carding rollers play roles such as opening and carding. Carding rollers are divided into needle rollers and card clothing rollers. A needle roller is a metal cylinder with steel needles implanted on its surface, and is installed in the drafting zone to control and card fibers. It is used in the no-twist roving frames of spun silk and wool spinning, the fine spinning frames of woolen spinning, and the fine spinning frames of spun silk and core silk spinning. A card clothing roller is a roller with a grooved surface around which metal card clothing or self-locking card clothing is wound on a smooth roller.

[0003] Firstly, in terms of structure, the needle roller adopts the design of directly implanting steel needles into a metal cylinder. This design makes the replacement and repair of steel needles quite difficult. Once the steel needles are worn or damaged, the entire needle roller may need to be overhauled or replaced, which not only increases the maintenance cost but also affects the production efficiency.

[0004] Secondly, although the card clothing roller can be maintained by replacing the card clothing, the card clothing itself also has the problem of easy wear. Especially the tip part of the card clothing is extremely easy to be damaged due to long-term friction with fibers. This not only affects the carding effect but also increases the frequency and cost of replacing the card clothing. Summary of the Utility Model

[0005] The invention purpose of the utility model is to overcome the defects described in the background art, so as to realize a textile carding needle winding belt structure. The fixed design of the U-shaped steel needle and the belt insertion holes simplifies the replacement and repair process, improves the equipment operation efficiency, reduces the downtime and maintenance cost, and at the same time, the belt structure composed of multiple layers of materials also enhances the durability.

[0006] To achieve the above invention purpose, the technical solution of the utility model is: a textile carding needle winding belt structure, including a belt, and the belt is composed of five layers of materials;

[0007] The five layers of materials include two layers of nitrile rubber layers, two layers of fabric layers, and a keel frame layer located between the two fabric layers;

[0008] U-shaped steel needles, the U-shaped steel needles are processed from 70# material, shaped like a "U", with a hardness of 62HRC, and their surfaces are highly polished;

[0009] A plurality of insertion holes for the U-shaped steel needles to penetrate are evenly arranged on the belt, and the U-shaped steel needles are fixed by the friction of the rubber on the belt.

[0010] In the above textile carding needle winding belt structure, the five layers of materials of the belt are firmly combined by hot pressing or adhesives.

[0011] In the above textile comb needle winding belt structure, the height of the U-shaped steel needle matches the thickness of the belt, ensuring that it can be firmly fixed on the belt after being inserted into the insertion hole.

[0012] In the above textile comb needle winding belt structure, both ends of the belt are provided with devices for fixing or connecting, so as to wrap the belt around a roller without needles on its surface.

[0013] Compared with the prior art, the textile comb needle winding belt structure of the present utility model has at least the following beneficial effects:

[0014] By simplifying the replacement and repair process, compared with the traditional needle roller, the U-shaped steel needle of the present invention is fixed through the insertion holes on the belt, making the replacement and repair process of the steel needle simpler and faster. This not only reduces the maintenance time and labor costs, but also improves the operating efficiency of the equipment.

[0015] Due to the simplification of the replacement and repair process of the steel needle, the downtime and production losses caused by equipment failures are reduced, and the overall maintenance cost of the carding roller is reduced.

[0016] At the same time, the belt structure composed of multiple layers of materials also improves the strength and durability of the belt, further reducing the maintenance cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The textile comb needle winding belt structure of the present utility model will be described in more detail below with reference to the drawings and through specific embodiments.

[0022] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0023] In the textile carding needle winding belt structure of this embodiment, the belt 1 is a key component of the textile carding needle winding belt structure, and its design fully considers multiple aspects such as wear resistance, strength, stability, and ease of maintenance. Refer to Figure 1 and Figure 3 , including the belt 1, which is composed of five layers of materials;

[0024] The five layers of materials include two nitrile rubber layers 103, two fabric layers 102, and a keel layer 101 located between the two fabric layers 102. The five layers of materials of the belt 1 are firmly bonded by hot pressing or adhesives.

[0025] Nitrile rubber layer 103: Located on the outer side of the belt, it is in direct contact with the fibers in the working environment. This layer of nitrile rubber has excellent wear resistance and anti-aging properties, can resist the friction of fibers and the erosion of the external environment, and ensures that the belt maintains a smooth and flat appearance during long-term use.

[0026] Fabric layer 102: Close to the lower side of the nitrile rubber layer, it is made of high-strength and wear-resistant fiber fabric. This layer of fabric not only enhances the overall strength of the belt but also improves its tensile and tear resistance. At the same time, the texture structure of the fabric layer helps to increase the friction between the belt and the fibers, making the U-shaped steel needles more stably fixed on the belt.

[0027] Keel layer 101: Located between the two fabric layers, it is the skeleton part of the belt. The keel layer is made of lightweight and high-strength materials such as carbon fiber or fiberglass. It provides a solid support for the belt, effectively preventing the belt from deforming and twisting during high-speed operation. In addition, the keel layer also has good impact resistance, which can protect the internal materials from the influence of external impacts.

[0028] The five-layer structure design of the belt ensures the uniform distribution and stable fixation of the U-shaped steel needles. This enables the carding roller to maintain a uniform and stable carding effect when carding fibers, improving product quality and production efficiency.

[0029] In this embodiment, refer to Figure 1 and Figure 3 , the U-shaped steel needle 2, the U-shaped steel needle 2 is processed from 70# material, with a "U" shape, a hardness of 62HRC, and its surface is highly polished.

[0030] The U-shaped steel needle 2 is processed from 70# material. 70# material is a high-quality high-carbon steel with high strength, high hardness, and good wear resistance, which is very suitable for manufacturing components that need to withstand high stress and high wear.

[0031] In terms of shape design, the U-shaped steel needle 2 adopts a "U" shape structure. This structure not only increases the contact area with the fibers, improves the carding effect, but also makes the fixation of the steel needle on the belt more stable. In addition, the "U" shape structure also has a certain elasticity, which can provide a certain buffering effect during the carding process and reduce the damage to the fibers.

[0032] In terms of hardness, the hardness of the U-shaped steel needle 2 reaches 62 HRC. This high hardness enables the steel needle to maintain a sharp cutting edge during the carding process, effectively removing impurities and lumps in the fibers. At the same time, the high hardness also enhances the wear resistance of the steel needle and extends its service life.

[0033] In addition to the material and shape, its surface is highly polished, which not only improves the smoothness of the steel needle, reduces the friction with the fibers, but also enhances the corrosion resistance of the steel needle. This surface treatment enables the steel needle to maintain good performance even in a humid or corrosive environment.

[0034] In this embodiment, the "U" shape structure and sharp cutting edge of the U-shaped steel needle 2 make the fiber carding more uniform and thorough, effectively removing impurities and lumps in the fibers and improving the carding quality.

[0035] The U-shaped steel needle 2 is squeezed and fixed by the frictional force between the insertion holes on the belt 1 and the rubber, achieving a stable fixation effect. Even on the carding roller running at high speed, the U-shaped steel needle 2 can remain stable and is not easy to loosen or fall off. See Figure 1 and Figure 2 , a plurality of insertion holes for the U-shaped steel needle 2 to penetrate are evenly arranged on the belt 1, and the U-shaped steel needle 2 is squeezed and fixed by the frictional force of the rubber on the belt 1. The height of the U-shaped steel needle 2 matches the thickness of the belt 1 to ensure that it can be firmly fixed on the belt 1 after being inserted into the insertion holes. Both ends of the belt 1 are provided with devices for fixation or connection to wrap the belt 1 around the roller without needles on its surface.

[0036] When the U-shaped steel needle 2 is inserted into the insertion holes, the rubber material on the belt 1 plays a key role. Rubber has good elasticity and frictional force, which can squeeze and fix the U-shaped steel needle 2 in all directions. This squeezing and fixing method is not only simple and easy to implement, but also can provide a lasting fixation effect. Even on the carding roller running at high speed, the U-shaped steel needle 2 can remain stable and is not easy to loosen or fall off.

[0037] To ensure that the U-shaped steel needle 2 can be firmly fixed on the belt 1, its height matches the thickness of the belt 1. This design enables the U-shaped steel needle 2 to be completely embedded in the belt 1 after being inserted into the insertion holes, forming an integral whole with the belt 1. This close fit not only enhances the stability of the fixation, but also can reduce the friction and wear between the steel needle and the belt, and extend the service life.

[0038] In addition, both ends of the belt 1 are provided with devices for fixing or connecting. These devices can be selected and adjusted according to actual requirements so as to wrap the belt 1 around a roller without needles on its surface. This design makes the installation and disassembly of the belt 1 more convenient and rapid, and at the same time improves the flexibility and adaptability of the carding roller.
