Description

Technical Field

[0001] This utility model relates to the field of fabric finishing equipment technology, and in particular to a fabric softening finishing machine. Background Technology

[0002] Fabric softening processes can be achieved through chemical and physical methods. Chemical methods use softeners to reduce the coefficient of friction between fibers, resulting in a softer effect. While effective, chemical methods require prolonged soaking of the fabric, which is inefficient and generates significant wastewater pollution, contradicting environmental protection principles. Physical methods, on the other hand, use friction, rolling, air blowing, and kneading to fatigue the fabric structure under external forces, relaxing internal stresses, reducing rigidity, and increasing softness. Physical softening processes can be completed quickly, are highly efficient, and are more environmentally friendly.

[0003] Existing physical methods for softening fabrics vary, each yielding unique results. A common method involves air-washing tension-free fabrics, where the fabric is subjected to wind force as it impacts the fence and the gaps between the fences, resulting in a loosely folded state. In this air-washing method, the fabric actively impacts the fence. The fabric, being low in density and lightweight, experiences minimal impact force. Furthermore, the impact is large-area, uniform, leading to low pressure on individual fabric sections. This makes it difficult for the fabric to release stress within these sections, resulting in poor softening effects and low processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a fabric softening finishing machine.

[0005] The technical solution to achieve the purpose of this utility model is: a fabric softening machine, which has a fabric conveying path, and a plurality of wrapping nodes are provided on the fabric conveying path. At least some of the wrapping nodes are rubbing nodes, and the rubbing nodes are distributed at intervals with their adjacent wrapping nodes. A first rubbing roller is installed on the rubbing node, and guide rollers are installed on the other wrapping nodes except for the rubbing nodes. The fabric softening machine also includes a second rubbing roller. Both the second rubbing roller and the first rubbing roller are corrugated rollers. The second rubbing roller and the first rubbing roller are located on both sides of the fabric conveying path, and the second rubbing roller and the first rubbing roller mesh with each other.

[0006] Furthermore, the number of second rubbing rollers is one, and the number of rubbing nodes is several. The first rubbing rollers on several rubbing nodes are arranged at intervals along the circumference of the second rubbing roller, and all the first rubbing rollers mesh with the same second rubbing roller. The number of rubbing nodes can be one or several. When the first rubbing rollers on several rubbing nodes simultaneously rub the fabric, the softening efficiency is higher. When the number of rubbing nodes is several, the number of second rubbing rollers can be several, with several rubbing nodes meshing with several second rubbing rollers in a one-to-one correspondence; the number of second rubbing rollers can also be one, with all the first rubbing rollers meshing with the same second rubbing roller. Compared to the former, the latter, where all the first rubbing rollers mesh with the same second rubbing roller, requires fewer second rubbing rollers, resulting in a simpler structure and more convenient fabric driving setup. Compared to several first rubbing rollers acting as driving rollers, the end of the second rubbing roller is connected to a rotation drive mechanism, making the driving setup of the fabric with one second rubbing roller as the driving roller more convenient.

[0007] Furthermore, the first rubbing roller and the guide roller are distributed at intervals along the fabric conveying path. This arrangement, with only one second rubbing roller and the first rubbing rollers at several rubbing nodes arranged at circumferential intervals along the second rubbing roller, maximizes the proportion of rubbing nodes among all fabric winding nodes, greatly utilizing the limited number of fabric winding nodes, maximizing the number of first rubbing rollers, and improving the fabric rubbing efficiency.

[0008] Furthermore, all the first kneading rollers are located on the same ring, and all the guide rollers are located radially outside the ring. This arrangement allows for more first kneading rollers to be installed in a smaller space, improving space utilization.

[0009] Furthermore, each of the first rubbing rollers is equipped with a corresponding pressure adjustment mechanism. The pressure adjustment mechanism includes a movable rod and a spring. The first rubbing roller is rotatably mounted on the corresponding movable rod, and the spring is connected to the movable rod. The spring and the movable rod exert a force that ensures the first rubbing roller always presses against the second rubbing roller and engages with it. In the pressure adjustment mechanism, the spring provides a preload, ensuring that the first rubbing roller on the movable rod always presses against the second rubbing roller and engages with it. During operation, not only can the movable rod be adjusted to accommodate fabrics of different thicknesses, but by adjusting the spring, the pressure between the first and second rubbing rollers can also be adjusted to obtain different rubbing effects.

[0010] Furthermore, the movable rod includes a screw and a nut. The nut is threaded onto the screw. A fixing block is spaced apart on the side of the nut away from the first kneading roller. The spring is a compression spring, fitted onto the screw. One end of the spring contacts the nut, and the other end contacts the fixing block. There are various ways to install the movable rod and the spring; the spring can be a tension spring or a compression spring. In the above structure, the nut, fixing block, and spring can all be located on the outside of the first kneading roller, providing more space on the outside of the first kneading roller for easier installation.

[0011] Furthermore, the axis of the second kneading roller is located on the extension line of the screw. This arrangement not only results in an aesthetically pleasing structure but also improves adjustment efficiency by allowing the screw to move radially along the second kneading roller when adjusting the pressure between the first and second kneading rollers.

[0012] Furthermore, the second kneading roller is axially movable and is connected to a linear drive mechanism, which drives it to reciprocate along its axial direction. During operation, the linear drive mechanism drives the second kneading roller to reciprocate along its axial direction. The reciprocating movement of the second and first kneading rollers rubs and pulls the fabric along its width, effectively reducing internal stress across the fabric's width and improving its kneading and softening efficiency.

[0013] Furthermore, the linear drive mechanism includes a rotating wheel and a connecting rod, with one end of the connecting rod eccentrically hinged to the rotating wheel and the other end hinged to the second kneading roller. The linear drive mechanism can be a cylinder, a lead cylinder, or an eccentric wheel / cam drive structure. Compared to cylinders and lead cylinders, the eccentric wheel / cam drive structure is simpler.

[0014] Furthermore, the first rubbing roller is a stainless steel corrugated roller, the second rubbing roller is a rubber corrugated roller, and the guide roller is a smooth roller. When the stainless steel corrugated roller and the rubber corrugated roller mesh, the deformation of the rubber corrugated roller can make the meshing surface between the stainless steel corrugated roller and the rubber corrugated roller larger, and the rubbing surface of the fabric is also larger, resulting in higher rubbing efficiency.

[0015] Furthermore, a tension sensor for detecting fabric tension is also installed on the fabric conveying path. The tension sensor can detect the fabric tension in real time, facilitating the adjustment of fabric pressure during the rubbing process.

[0016] Furthermore, the tension sensor is mounted on the guide roller. One or more guide rollers are guide rollers with tension sensors. The guide rollers provide mounting brackets for the tension sensor, simplifying the installation of the tension sensor.

[0017] Furthermore, a wide-width roller is also provided on the fabric conveying path. The wide-width roller is used to spread the fabric, prevent the fabric from wrinkling, and improve the stability of fabric operation and the uniformity of fabric rubbing.

[0018] Furthermore, the wide-width rollers are present between all adjacent rubbing nodes. This arrangement ensures that the fabric entering between each of the first and second rubbing rollers is unfolded and wrinkle-free.

[0019] This utility model relates to a fabric softening machine. Through the arrangement of a second rubbing roller and a first rubbing roller, and utilizing their meshing relationship, the machine kneads and twists the fabric passing between the second and first rubbing rollers. During this kneading and twisting, the fabric is subjected not only to radial pressure from the second and first rubbing rollers, causing fatigue and stress, but also to bending and deformation. This bending deformation causes localized stretching and fatigue of the fabric structure. The combined effect of radial pressure kneading and bending deformation rapidly fatigues the fabric, loosening its internal structure, reducing its rigidity, and completing the fabric softening process. This method is fast and efficient. Furthermore, the wavy edges of the second and first rubbing rollers of the wave roller are not only regular but also have a high density, which allows the fabric pressed between the second and first rubbing rollers to form uniform creases while also having a very high density of creases. The fabric with uniform and high crease density can be twisted in various local areas, resulting in high twisting efficiency and good softness.

[0020] In addition, in this utility model of fabric softening finishing machine, the rubbing nodes are distributed at intervals with their adjacent wrapping nodes. Under the wrapping pull of the adjacent wrapping nodes, the fabric passing through the rubbing nodes has a larger tension. When the fabric with a larger tension is rubbed and twisted by the first rubbing roller and the second rubbing roller, the fabric is subjected to a greater force. Under this greater force, the fabric structure fatigues faster and the softening process is more efficient. Attached Figure Description

[0023] The preferred embodiment of the fabric softening finishing machine of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, a fabric softening machine has a fabric conveying path 10, on which a plurality of fabric winding nodes 101 are provided. At least some of the fabric winding nodes are rubbing nodes 101'. The rubbing nodes 101' are distributed at intervals with their adjacent fabric winding nodes 101. A first rubbing roller 1 is installed on the rubbing node 101'. Guide rollers 3 are installed on all the fabric winding nodes 101 except for the rubbing nodes 101'. The fabric softening machine also includes a second rubbing roller 2. The second rubbing roller 2 and the first rubbing roller 1 are both wave rollers. The second rubbing roller 2 and the first rubbing roller 1 are located on both sides of the fabric conveying path 10, and the second rubbing roller 2 and the first rubbing roller 1 are meshed.

[0025] This utility model relates to a fabric softening and finishing machine. The fabric on the fabric conveying path 10 is sequentially wound around the first kneading roller 1 and the guide roller 3, and conveyed along the fabric conveying path 10. During the conveying process, the meshing second kneading roller 2 and the first kneading roller 1 knead and twist the passing fabric, causing fabric fatigue, loosening the internal stress of the fabric structure, reducing the rigidity of the fabric, and achieving the softening process.

[0026] This utility model relates to a fabric softening machine. Through the arrangement of the second kneading roller 2 and the first kneading roller 1, and utilizing their meshing relationship, the machine kneads and twists the fabric passing between the second and first kneading rollers. During this kneading and twisting process, the fabric is subjected not only to radial pressure from the second and first kneading rollers, causing fatigue and stress, but also to bending and deformation. This bending deformation causes localized stretching and fatigue of the fabric structure. The combined effect of radial pressure kneading and bending deformation rapidly fatigues the fabric, loosening its internal structure, reducing its rigidity, and completing the fabric softening process. This method is fast and efficient. Furthermore, the wavy edges of the second rubbing roller 2 and the first rubbing roller 1 of the wave roller are not only regular but also have a high density, which makes the fabric pressed between the second rubbing roller 2 and the first rubbing roller 1 form uniform creases while the density of the creases is also very high. The fabric with uniform and high crease density can be twisted in various local areas, resulting in high twisting efficiency and good softness.

[0027] In addition, in the fabric softening machine of this utility model, the kneading node 101' and its adjacent winding node 101 are distributed at intervals. Under the winding pull of the adjacent winding node 101, the fabric passing through the kneading node 101' has a larger tension. When the fabric with a larger tension is kneaded and twisted by the first kneading roller 1 and the second kneading roller 2, the fabric is subjected to a greater force. Under this greater force, the fabric structure fatigues faster and the softening process is more efficient.

[0028] In this invention, a fabric softening machine preferably has one second rubbing roller 2 and several rubbing nodes 101'. The first rubbing rollers 1 on the several rubbing nodes 101' are arranged at intervals along the circumference of the second rubbing roller 2, and all the first rubbing rollers 1 mesh with the same second rubbing roller 2. The number of rubbing nodes 101' can be one or several. When the first rubbing rollers 1 on several rubbing nodes 101' simultaneously rub the fabric, the softening process is more efficient. When the number of rubbing nodes 101' is several, the number of second rubbing rollers 2 can be several, with each of the several rubbing nodes 101' meshing with a corresponding number of second rubbing rollers 2; alternatively, the number of second rubbing rollers 2 can be one, with all the first rubbing rollers 1 meshing with the same second rubbing roller 2. Compared to the former, when all the first rubbing rollers 1 are engaged with the same second rubbing roller 2, the latter has fewer second rubbing rollers 2, a simpler structure, and a more convenient fabric driving setup. Compared to several first rubbing rollers 1 acting as active rollers, the end of the second rubbing roller 2 is connected to a rotation drive mechanism 20, making the fabric driving setup with one second rubbing roller 2 acting as the active roller more convenient.

[0029] In this invention, a fabric softening and finishing machine is preferably provided in which the first rubbing roller 1 and the guide roller 3 are distributed at intervals along the fabric conveying path 10. This arrangement, when the number of second rubbing rollers 2 is one, and the first rubbing rollers 1 on several rubbing nodes 101' are arranged at circumferential intervals along the second rubbing roller 2, maximizes the proportion of rubbing nodes 101' among all the wrapping nodes 101, greatly utilizing the limited number of wrapping nodes 101, maximizing the number of first rubbing rollers 1, and improving the fabric rubbing efficiency.

[0030] In this fabric softening machine, preferably, all the first rubbing rollers 1 are located on the same circular ring 11, and all the guide rollers 3 are located radially outside the circular ring 11. This arrangement allows for more first rubbing rollers 1 to be installed in a smaller space, improving space utilization.

[0031] In this invention, a fabric softening and finishing machine is preferably provided with a pressure adjusting mechanism 4 for each of the first rubbing rollers 1. The pressure adjusting mechanism 4 includes a movable rod 41 and a spring 42. The first rubbing roller 1 is rotatably mounted on the corresponding movable rod 41. The spring 42 is connected to the movable rod 41, and the spring 42 and the movable rod 41 exert a force that allows the first rubbing roller 1 to always press against and engage with the second rubbing roller 2. In the pressure adjusting mechanism 4, the spring 42 provides a preload, ensuring that the first rubbing roller 1 on the movable rod 41 always presses against and engages with the second rubbing roller 2. During operation, not only can the movable rod 41 be moved to adapt to fabrics of different thicknesses, but by adjusting the spring 42, the pressure between the first rubbing roller 1 and the second rubbing roller 2 can also be adjusted to obtain different rubbing effects.

[0032] In this invention, a fabric softening and finishing machine, preferably, the movable rod 41 includes a screw 411 and a nut 412. The nut 412 is threaded onto the screw 411. A fixing block 43 is spaced apart on the side of the nut 412 away from the first kneading roller 1. The spring 42 is a compression spring, sleeved on the screw 411. One end of the spring 42 contacts the nut 412, and the other end contacts the fixing block 43. The movable rod 41 and the spring 42 can be installed in various ways; the spring 42 can be a tension spring or a compression spring. With the above structure, the nut 412, fixing block 43, and spring 42 can all be located on the outside of the first kneading roller 1, providing more space on the outside of the first kneading roller 1 for easier installation.

[0033] In this fabric softening machine, preferably, the axis of the second rubbing roller 2 is located on the extension line of the screw 411. This arrangement not only results in an aesthetically pleasing structure but also improves adjustment efficiency by allowing the screw 411 to move radially along the second rubbing roller 2 when adjusting the pressure between the first rubbing roller 1 and the second rubbing roller 2.

[0034] In this invention, a fabric softening and finishing machine preferably includes a second rubbing roller 2 that is axially movable. The second rubbing roller 2 is connected to a linear drive mechanism 21 and is driven by the linear drive mechanism 21 to move axially reciprocally. During operation, the linear drive mechanism 21 drives the second rubbing roller 2 to move axially reciprocally. The reciprocating second rubbing roller 2 and the first rubbing roller 1 rub and pull the fabric along its width, effectively reducing internal stress across the fabric width and improving the rubbing and softening efficiency.

[0035] In this invention, a fabric softening and finishing machine is preferably provided in which the second rubbing roller 2 is axially movable. The second rubbing roller 2 is connected to a linear drive mechanism 21 and is driven by the linear drive mechanism 21 to reciprocate along the axial direction of the second rubbing roller 2. The linear drive mechanism 21 can be a cylinder, a yarn cylinder, or an eccentric wheel or cam drive structure. Compared to cylinders and yarn cylinders, the eccentric wheel or cam drive structure is simpler.

[0036] In this invention, a fabric softening and finishing machine is preferably constructed in which the first rubbing roller 1 is a stainless steel corrugated roller, the second rubbing roller 2 is a rubber corrugated roller, and the guide roller 3 is a smooth roller. When the stainless steel corrugated roller and the rubber corrugated roller mesh, the deformation of the rubber corrugated roller allows for a larger meshing surface between them, resulting in a larger rubbing surface on the fabric and higher rubbing efficiency.

[0037] Preferably, in this fabric softening machine, the fabric conveying path 10 is further equipped with a tension sensor 5 for detecting fabric tension. The tension sensor 5 can detect the fabric tension in real time, facilitating the adjustment of fabric pressure during the kneading process.

[0038] In this fabric softening machine, preferably, the tension sensor 5 is mounted on the guide roller 3. One or more guide rollers 3 are guide rollers with tension sensors. The guide roller 3 provides a mounting bracket for the tension sensor 5, simplifying the installation of the tension sensor 5.

[0039] In this invention, a fabric softening and finishing machine is preferably provided with a wide-width roller 6 on the fabric conveying path 10.
