Abstract
Description
Technical Field
[0001] This utility model relates to the field of needle cloth, and more particularly to double-sided track needle cloth. Background Technology
[0002] In the textile industry, carding cloth, as a core component of carding machinery, plays a crucial role in opening, separating, removing impurities, and orienting fiber bundles. Its performance directly affects the quality and production efficiency of textiles. From early metal carding cloths to today's new composite material carding cloths, with the diversification of textile raw materials and the continuous improvement of textile quality requirements, the technological development of carding cloths has always been closely linked to industry needs. Whether it is natural fibers such as cotton, wool, silk, and linen, or various chemical fibers, they all require precise carding by carding cloths to achieve uniform fiber distribution and single-fiber formation. Therefore, the structural design and carding efficiency of carding cloths have always been key research directions in the field of textile machinery.
[0003] In existing technologies, commonly used carding cloths mainly consist of two parts: a base and needles. The base is usually made of a material with a certain degree of elasticity and strength to ensure stable operation on high-speed carding machines. The needles are mostly made of metal and are fixed to the surface of the base through processes such as welding and needle insertion, forming a regularly arranged tooth structure. The technical principle is to utilize the sharp edges and rational arrangement of the needles to tear and separate the fiber bundle into individual fibers through friction, gripping force, and relative movement between the needles and fibers as the fiber bundle passes through the carding area. This process removes impurities and short fibers while simultaneously orienting the fibers along the carding direction, providing high-quality fiber raw materials for subsequent spinning processes. Currently, commercially available carding cloths are adjusted in parameters such as tooth height, tooth density, and tooth shape depending on their application and the object being carded.
[0004] However, existing carding cloths, due to their single-structure needle tooth design, have fixed lengths and angles, making it difficult to achieve targeted carding control when dealing with fiber bundles of varying thicknesses and properties. When processing coarser, harder fiber bundles, insufficient needle tooth parameter adaptation can easily lead to excessive stretching and breakage of the fibers. Conversely, when processing finer, softer fiber bundles, insufficient carding force or insufficient application points can result in some fiber bundles not being effectively carded, leading to missed carding and affecting the uniformity of the fibers after carding and the overall carding efficiency. Therefore, a double-sided carding cloth is proposed to address these issues. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a double-sided guide plate needle cloth, which aims to improve the problem that existing products are difficult to achieve targeted combing control when facing fiber bundles of different thicknesses and characteristics.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] The double-sided guide plate needle cloth includes a woven cloth. One side of the woven cloth is fixedly connected to multiple needle teeth 1, and the other side of the woven cloth is fixedly connected to multiple needle teeth 2. Each needle tooth 1 and needle tooth 2 has multiple forked strips fixedly connected to one end. One side of the woven cloth is provided with multiple cleaning grooves 1, and the other side of the woven cloth is provided with multiple cleaning grooves 2.
[0008] As a further description of the above technical solution:
[0009] Each of the needle teeth is at a 90-degree angle to the fabric and uses a rounded corner transition.
[0010] As a further description of the above technical solution:
[0011] The distance between one end of each of the needle teeth and the fabric is 30 degrees, and a rounded corner transition is used.
[0012] As a further description of the above technical solution:
[0013] The other ends of the multiple needle teeth one and two are all made of teardrop structure, and the length of the needle tooth one is longer than that of the needle tooth two.
[0014] As a further description of the above technical solution:
[0015] The first cleaning groove is located between the first needle teeth on both adjacent sides, and the second cleaning groove is located between the second needle teeth on both adjacent sides.
[0016] As a further description of the above technical solution:
[0017] The inner walls of both cleaning groove one and cleaning groove two are circular arc structures.
[0018] This utility model has the following beneficial effects:
[0019] 1. In this utility model, by setting two types of needles with different lengths and angles, the coarse combing and fine combing are combined to achieve comprehensive combing of the fiber bundles. This solves the problem that existing single-structure card cloths are prone to over-combing or under-combing of fibers, and enhances the comprehensive processing effect on different fiber bundles. At the same time, by setting bifurcated strips on the needles, the number of combing points is increased without changing the tooth density, achieving a more refined combing effect. This solves the problem that traditional card cloths are insufficient in combing fine fibers, and enhances the control and processing capabilities of high-value-added fine fibers.
[0020] 2. In this utility model, the teardrop-shaped structure at the tip of the needle teeth transforms the piercing action on the fibers into a gentle peeling action, achieving a gentle combing effect. This solves the problem of poor yarn quality caused by fiber damage and breakage, and enhances the quality of the final yarn. In addition, by setting the rounded transition at the root of the needle teeth and the cleaning groove between the teeth, cleaning dead corners are eliminated, which prevents fiber entanglement and accumulation. This solves the problem of fiber entanglement at the root causing cleaning difficulties and machine stoppages, and enhances the self-cleaning ability of the needle cloth and the stability of continuous operation.

[0028] 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.
[0029] Reference Figures 1-5This utility model provides an embodiment of a double-sided guide plate needle cloth, comprising a woven fabric 1. Multiple needle teeth 1 2 are fixedly connected to one side of the woven fabric 1. These needle teeth 1 2, due to their relatively long length, are used to create a strong gripping effect, performing preliminary coarse combing on loosened large fiber bundles. Multiple needle teeth 2 5 are fixedly connected to the other side of the woven fabric 1. These needle teeth 2 5, due to their shorter length, can better conform to the fiber surface, improving the smoothness of the fiber surface for fine combing. Multiple branch strips 3 are fixedly connected to one end of each needle tooth 1 2 and needle tooth 2 5. These branch strips 3 are used to... By increasing the number of combing points while maintaining a high density of teeth, a finer and more thorough combing process is achieved, enhancing control over individual fibers. Multiple cleaning grooves 4 are located on one side of the fabric 1, and multiple cleaning grooves 6 are located on the other side. One end of multiple needle teeth 2 is at a 90-degree angle to the fabric 1. This angle design is used to create a strong gripping force in conjunction with the fabric's length characteristics, and a rounded transition is used. This rounded transition, along with the cleaning grooves 4, eliminates dead angles between the needle teeth and the fabric 1, solving the problem of fibers easily tangling at the root. One end of multiple needle teeth 25 is at a 30-degree angle to the fabric 1. The angled design improves smoothness by better conforming to the fiber surface, and the rounded corner transition is also incorporated. This structure, along with cleaning groove 6, enhances the self-cleaning properties of the card cloth. Multiple needle teeth 1 (2) and 2 (5) feature a teardrop structure at their other ends. This structure transforms the contact between the needle tip and the fiber from sharp piercing to gentle peeling, gently separating the fiber bundles. This solves the problem of reduced yarn quality caused by fiber breakage, enhancing the final yarn quality. Needle teeth 1 (2) are longer than needle teeth 2 (5), and this length difference allows them to work together, forming a relay coordination of "coarse combing" and "fine combing," solving the problem of fiber breakage. This design solves the problem of fiber bundles being easily over-combed or under-combed in a single structure, enhancing the overall combing effect on different fiber bundles. Cleaning groove 1 4 is located between adjacent needle teeth 1 2 on both sides, and cleaning groove 2 6 is located between adjacent needle teeth 2 5 on both sides. Together, they provide a channel for fine impurities and short fibers to slide off, solving the problem of impurities easily accumulating and getting stuck at the root. The inner walls of cleaning groove 1 4 and cleaning groove 2 6 are both arc-shaped structures. This design is used to form a smooth ramp, making it impossible for impurities to find a stable "stuck" point, thus enhancing the self-cleaning ability of the card cloth and the stability of continuous operation.
[0030] Working principle: During product use, the longer length of needle tooth 2 and its 90-degree angle with the fabric 1 create a strong gripping effect, which is used to comb loose large fiber bundles. The angle between needle tooth 2 and the fabric 1 is 30 degrees, and its length is shorter than that of needle tooth 2, allowing needle tooth 2 5 to better fit the fiber surface and improve the smoothness of the fiber surface. Through this relay cooperation of coarse and fine combing, the problem of fiber bundles being easily over-combed or under-combed in a single structure is solved, enhancing the overall combing effect on different fiber bundles. At the same time, by utilizing the multiple branch strips 3 on the surface of needle tooth 2 and needle tooth 2 5, the number of combing points is multiplied without changing the overall tooth density, enhancing the control over individual fibers and achieving finer and more thorough combing. This solves the problem of insufficient combing ability of traditional card cloth for fine fibers and enhances the ability to process high-value-added fine fibers.
[0031] In preventing fibers from entangled on the product surface, the teardrop-shaped structure at one end of needle teeth 1-2 and 2-5 transforms the contact between the needle tip and the fiber from pure sharp piercing to gentle peeling. It gently slides into the fiber bundle and separates them, rather than roughly cutting or damaging the fibers, thereby significantly reducing the short fiber rate and solving the problem of reduced yarn quality caused by fiber breakage, thus enhancing the quality of the final yarn. At the same time, the rounded transition structure between needle teeth 1-2 and 2-5 and the fabric 1, along with the cleaning grooves 1-4 and 2-6 located between adjacent needle teeth, eliminates the dead angle between the needle tooth root and the fabric 1, forming a smooth ramp. This prevents fine materials from being stably stuck when they slide to the needle tooth root, solving the problem of fibers easily entangled at the needle tooth root, causing cleaning difficulties and machine stoppages, and enhancing the self-cleaning properties of the needle cloth and the stability of continuous operation.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
