Description

Technical Field

[0001] This utility model relates to the technical field of knitted fabric napping treatment device, specifically a knitted fabric napping treatment device. Background Technology

[0002] In the textile industry, especially in the processing of knitted fabrics, napping is a key process for improving product texture, functionality, and market competitiveness. As consumer demand for the softness, warmth, and appearance of knitted fabrics continues to rise, the application of napping technology has expanded from traditional sweatshirt fabrics and fleece fabrics to niche markets such as infant underwear, home textiles, and high-end apparel, placing higher demands on the uniformity of napping, fabric protection, and equipment compatibility.

[0003] Currently, the raising of knitted fabrics mainly involves the raising roller and the conveying roller rotating in opposite directions. This allows the fine needles on the raising roller to hook up the pile of the knitted fabric located on the conveying roller, thereby forming a pile layer on the surface of the knitted fabric and achieving the raising effect. For example, a Chinese patent with publication number CN211772094U discloses a knitted fabric raising device, which uses multiple raising machines connected in parallel and series, and sets sensors between adjacent raising machines. This connection method makes the entire raising process standardized and intelligent, eliminates the phenomenon of fabric breakage and equipment damage, standardizes the process, improves efficiency, and saves energy.

[0004] In the aforementioned literature, due to the static electricity generated by friction between knitted fabrics and various materials during the production process, existing napping devices cannot eliminate the static electricity on knitted fabrics. The presence of static electricity causes the formed fuzz to adhere to the surface of the fabric, thereby affecting the appearance quality and warmth retention of the fabric. Furthermore, it is impossible to perform pre-treatment on the fabric before napping. When the fabric fibers are tightly woven, the direct strong napping by the napping wheel can easily lead to fabric damage and affect the fabric quality. Therefore, a napping device for knitted fabrics is proposed to address the above problems. Utility Model Content

On the base plate 1, a take-up roller 116 is provided on the side opposite to the equipment box 11 of the second extrusion assembly 4. The two guide shafts 113, the fourth guide shaft 112, the first guide shaft 14, and the take-up roller 116 are all located on the same horizontal plane.

The first copper plate 114 is fixed to the bottom of the plurality of second limiting rods 42 in another second pushing assembly 4.

[0022] Each of the second limiting rods 42 is fitted with a second spring 43. One of the second springs 43 in the second pushing assembly 4 is located between the second copper plate 115 and the bracket 41, and the other second spring 43 in the second pushing assembly 4 is located between the first copper plate 114 and the bracket 41. Each of the ends of the second limiting rods 42 is fixedly connected to a second baffle 44. Both the first copper plate 114 and the second copper plate 115 are grounded through wires.

[0023] The first pushing assembly 2 includes a first slider 21 slidably disposed in the second through groove 111, and two sanding rollers 19 are respectively rotatably installed between two opposite first sliders 21 in the two first pushing assemblies 2. A fixing plate 22 is fixedly connected to the first slider 21. A first limiting rod 23 is fixedly connected below the fixing plate 22 at the end of one of the sanding rollers 19. A sliding plate 24 is slidably disposed on the first limiting rod 23, and the sliding plate 24 is fixed below the opening of the corresponding second through groove 111. The first limiting rod 23 at the end of the other sanding roller 19 is fixed above the fixing plate 22 in its corresponding first pushing assembly 2, and the sliding plate 24 is fixed above the opening of the corresponding second through groove 111.

[0024] Each of the first limiting rods 23 is fitted with a first spring 25, and the first spring 25 is located between the fixed plate 22 and the sliding plate 24. Each of the first limiting rods 23 is fixedly connected to a first baffle 26. Each of the first sliders 21 is fixed with a motor 117 on its side, and the output ends of the two motors 117 are respectively connected to the rotation center shaft of the two sanding rollers 19.

[0025] Each end of the first pressure roller 17 has a first through groove 110 on the side wall of the equipment box 11. Each first through groove 110 is provided with an adjustment component 3. The adjustment component 3 includes a second slider 31 that is slidably disposed in the first through groove 110. The first pressure roller 17 is rotatably mounted between the two second sliders 31. A fixing seat 32 is fixed to the side of the second slider 31. A pressure sensor 33 is fixed on the fixing seat 32. An electric telescopic rod 34 is installed on the pressure sensor 33 and fixed to the outer wall of the equipment box 11.

[0026] During operation, knitted fabrics generate static electricity through friction with various materials during production. Existing napping devices cannot eliminate this static electricity, causing fuzz to adhere to the fabric surface, affecting its appearance and warmth. Furthermore, pre-treatment before napping is impossible. When the fabric fibers are tightly woven, direct, forceful napping by the napping rollers can easily damage the fabric, impacting its quality. In this solution, the first push at the ends of the two sanding rollers 19 in their initial state... Component 2 pushes the two sanding rollers 19 to the upper and lower sides respectively. The first spring 25 in the first pushing component 2 at the end of the two sanding rollers 19 pushes the fixed plate 22 upward and downward respectively, so as to drive the first slider 21 to slide upward and downward in the corresponding second through groove 111 respectively, thereby causing the two sanding rollers 19 to be misaligned vertically. The second spring 43 in the two second pushing components 4 pushes the first copper plate 114 and the second copper plate 115 upward and downward respectively, so as to cause the first copper plate 114 and the second copper plate 115 to be misaligned vertically. In use, the fabric is fed into the equipment box 11 through the feed port 12, then wound up through the first guide shaft 14 and fed upwards. Then it is wound through the second guide shaft 15 on the side away from the first pressure roller 17. The fabric is then wound back and forth in an S-shape on multiple licker rollers 16. Then it is wound through another second guide shaft 15 and fed downwards. Then it is wound under the first pressure roller 17 and wound and fed above the third guide shaft 18 on the side close to the first pressure roller 17. Then the fabric is wound in an S-shape through two sanding rollers 19. After being wound under the fourth guide shaft 112, it is led out from the discharge port 13. After the fabric is led out, it passes between the two fifth guide shafts 113, the lower surface of the first copper plate 114 and the upper surface of the second copper plate 115 in sequence. Finally, the end of the fabric is fixed on the take-up roller 116 for take-up to complete the take-up connection of the fabric. Under the winding action of the take-up roller 116, the fabric weaving drives multiple quilling rollers 16 to rotate. While the quilling rollers 16 prevent needle punctures, they lightly puncture the fabric surface, loosening the fiber structure and preventing subsequent strong pilling that could damage the fabric surface. During the fabric winding process, two motors 117 are controlled to operate. When the motors 117 operate, they drive two sanding rollers 19 to rotate, and the rotation direction of the two sanding rollers 19 is opposite to the winding direction of the fabric. This allows the sandpaper on the surface of the sanding rollers 19 to rub against the fabric fibers. Through sandpaper friction, the fibers break and stand up to form a pile layer. Furthermore, due to the different mesh sizes of the sandpaper, the coefficient of friction varies. Different sandpapers have different frictional forces on the fabric, so different lengths of pile layers can be formed by changing the sandpaper with different mesh sizes. In addition, under the action of the first spring 25, the two sandpaper rollers 19 are made to fit tightly against the fabric surface to ensure the friction effect. During the fabric winding process, the first pressure roller 17 will be pushed upward under the action of the fabric winding tension. The first pressure roller 17 will then transmit the thrust to the pressure sensor 33 to monitor the tension of the fabric winding. By controlling the extension and retraction of the electric telescopic rod 34, the first pressure roller 17 can be moved up and down, thereby adjusting the winding tension of the fabric. Furthermore, the fabric will form static electricity adsorption when it is rubbed by the sanding roller 19. As the fabric is wound, it will be conveyed to the bottom of the first copper plate 114 and the top of the second copper plate 115. Under the action of the second spring 43, the first copper plate 114 and the second copper plate 115 will be attached to the upper and lower surfaces of the fabric respectively. Under the conductive effect of the first copper plate 114 and the second copper plate 115, the static electricity on the surface of the fabric will be discharged to achieve the effect of static electricity elimination, thereby ensuring the appearance quality of the fabric. The combination achieves the effect of raising the fabric, effectively preventing the fabric from being damaged under the strong action of the raising wheel, and can also eliminate static electricity generated during the fabric production process, thereby ensuring the appearance quality and warmth retention of the fabric.
