Description

Technical Field

[0001] This utility model relates to the textile printing and dyeing industry, specifically to a multi-sided abrasive roller used for abrasiveing, napping, and finishing of fabrics. Background Technology

[0002] Currently, most sanding rollers on the market use a circular roller structure. This traditional design has significant limitations in practical applications. When a circular roller comes into contact with the fabric, its sanding effect is concentrated only on the surface layer of the fabric. Due to the circumferential shape of the roller, it is difficult to penetrate deep into the internal fiber structure of the fabric. Taking knitted fabrics as an example, the pores formed by the interlacing of the yarns and the internal fiber bundles cannot be effectively treated due to the surface-level sanding characteristic of the circular roller, resulting in sparse nap and insufficient three-dimensionality on the surface of the fabric after sanding.

[0003] From a process parameter perspective, due to the limited action of circular rollers, the abrasion area and depth that a single abrasion roller can handle per unit time have an upper limit, making it difficult to meet the abrasion efficiency and density requirements for high-quality fabric production. To compensate for this deficiency, manufacturers often need to increase the number of abrasion rollers to improve the abrasion effect. However, this approach not only significantly increases equipment purchase costs and floor space but also significantly increases energy consumption. According to industry data, under the same production capacity requirements, a abrasion production line using traditional circular abrasion rollers has 30%-40% higher equipment investment costs and 25%-35% higher energy consumption than the optimized solution. Therefore, breakthroughs in abrasion roller structural design are urgently needed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a multi-sided grinding roller with higher grinding efficiency and more uniform grinding density.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a polygonal abrasive roller, characterized in that: it includes a polygonal roller body and abrasive skin; the cross-section of the polygonal roller body is a polygonal structure, and the abrasive skin is included on the surface of the polygonal roller body.

[0006] Furthermore, the polygonal roller has 3-30 sides.

[0007] Furthermore, the polygonal roller has 16, 18, or 20 sides.

[0008] Furthermore, the sandpaper is tightly wrapped around the surface of the polygonal roller body with an adhesive, and is firmly bonded to the edges of the polygon to form an integrated structure.

[0009] Furthermore, the abrasive skin is wrapped around the surface of the polygonal roller body, and the abrasive skin contacts the vertices of the polygon, with gaps between the abrasive skin and the edges of the polygon between adjacent vertices.

[0010] The beneficial effects of this utility model are as follows: This invention innovatively abandons the traditional circular grinding roller design concept, adopting a polygonal roller structure (preferably a 16 / 18 / 20-sided polygonal roller). Special abrasive is tightly wrapped around the surface of the polygonal roller. When the fabric comes into contact with the roller surface, the unique polygonal contour causes the fabric surface to produce a periodic slapping vibration effect. Compared to the smooth contact method of traditional grinding rollers, this structure significantly enhances the abrasive force through the high-frequency impact at the edges. With each rotation of the polygonal roller, the fabric surface undergoes multiple (e.g., 16, 18, or 20) precise slaps. This high-frequency mechanical action can quickly loosen the internal structure of the fabric.

[0011] When processing warp-knitted fleece fabrics, the beating process not only loosens the fibers but also precisely controls the pile height to achieve the ideal 2.5mm through the cutting action of the angular edges. Multiple experimental data show that compared to traditional equipment, this multi-roller napping machine improves napping efficiency while reducing the coefficient of variation in pile density on the fabric surface, achieving a high degree of uniformity in napping density. This innovative beating vibration structure not only significantly improves napping efficiency but also, by altering the way the fibers interact, endows the fabric with a unique, delicate touch and rich texture, significantly optimizing the quality and style of napped products.

[0016] The technical solution of this utility model will be clearly and completely described below through specific embodiments. Example 1

[0017] refer to Figure 2 This invention relates to a multi-sided roller sanding machine, the core structure of which consists of a multi-sided roller body 1 and sandpaper 2. The multi-sided roller body 1, as the core load-bearing component of the equipment, has a polygonal geometric design in its cross-section. This unique structure significantly improves the efficiency and precision of the sanding operation. The sandpaper 2 is tightly wrapped around the surface of the multi-sided roller body 1. Through special processing, a seamless fit between the sandpaper and the roller body is ensured, thereby achieving a uniform and stable sanding effect.

[0018] In the design of the polygonal roller body 1, the selection of the number of polygonal sides is crucial, and the preferred standard specifications are 16 sides, 18 sides and 20 sides.

[0019] The 16-sided polygonal roller body is suitable for basic napping of conventional fabrics and can quickly remove loose fibers from the fabric surface; the 18-sided polygonal roller body retains efficient napping capabilities while focusing on the fineness of napping, and is suitable for fine processing of mid-to-high-end fabrics; while the 20-sided polygonal roller body has extremely high napping precision and is often used for high-end fabrics with demanding surface texture requirements.

[0020] In practical industrial applications, operators can flexibly select the appropriate multi-sided roller body specifications based on different abrasion requirements such as the material characteristics of the fabric and the quality standards of the finished product, so as to achieve precise and customized operation of the abrasion process.

[0021] During operation, the abrasive roller of the polygonal roller napping machine is installed on the napping machine. When the polygonal roller body 1 rotates, the abrasive 2 wrapped around its surface rotates along with it. After the fabric surface comes into contact with the roller surface of the polygonal roller body 1, due to the polygonal structure of the roller body 1, a patting vibration effect is created. For each rotation, the roller surface pats the fabric surface the number of times it does so, equal to the number of sides of the polygon, i.e., 16, 18, or 20 times. Through this patting vibration, the fabric's structure is loosened and made easier to nap. Simultaneously, for warp-knitted fabrics, the patting effectively cuts the fibers to achieve a nap height of 2.5mm. Example 2

[0022] Unlike Example 1, in this example, the abrasive pad 2 wraps around the surface of the polygonal roller body 1, and the abrasive pad 2 only contacts the vertices of the polygon. The abrasive pad between adjacent vertices is suspended, with gaps between it and the edges of the polygon. During actual installation and debugging, the polygonal roller body is first fixed to the frame of the sanding machine using bearing seats, with the axial direction of the polygonal roller body perpendicular to the fabric conveying direction. The abrasive pad is made of a special elastic material and is precisely fixed to each vertex of the polygonal roller body using a high-strength adhesive. To ensure the stability of the abrasive pad under high-speed rotation, a positioning clamp is used to precisely position the abrasive pad before the adhesive cures, ensuring a tight and uniform fit between the abrasive pad and the vertices of the polygonal roller body.

[0023] When the abrasive pad rotates with the polygonal roller and comes into contact with the fabric, the gap between the abrasive pad and the apex causes the abrasive pad to elastically deform upon contact, creating an effect similar to an "elastic pat." The force of this elastic pat comes not only from the rotational inertia of the polygonal roller but also from the elastic recovery force of the abrasive pad itself. Compared to the structure in Example 1 where the abrasive pad is completely adhered to the polygonal roller, the elastic patting effect in this embodiment generates stronger vibration waves that can penetrate deeper into the fabric's structure.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Those skilled in the art can make various modifications or equivalent substitutions to the present utility model within its substance and protection scope, and such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present utility model's technical solution.
