Description

Technical Field

[0001] The utility model relates to fabric production equipment, in particular to a device for removing wrinkles from the surface of elastic fabric. Background Art

[0002] Elastic fabrics undergo post-processing during production, including a flattening and shaping process to achieve the desired dimensional stability, form, and performance. This process typically involves using heat-setting equipment to heat and roll the fabric, achieving a more uniform texture. Once the fabric cools, it maintains a flat state. However, since elastic fabrics may already be wrinkled before the flattening process, it is best not to remove wrinkles. Wrinkles in the fabric will result in serious quality defects after entering the heat-setting equipment. Therefore, there is a need for a wrinkle-removing device specifically designed for elastic fabrics that can be used to flatten the fabric before flattening and shaping. Summary of the Invention

[0003] The utility model provides a device for removing wrinkles from the surface of elastic fabrics, which solves the problem in the prior art that the fabrics need to be flattened and wrinkle-removed before being heat-set.

[0004] The above technical problems of the present invention are mainly solved by the following technical solutions: a device for removing wrinkles from the surface of elastic fabrics, comprising a bracket and two flattening modules rotatably arranged at both ends of the bracket, the two flattening modules being mirror images of the bracket; the flattening module comprising an upper cover, a lower cover and a rotating shaft vertically rotatably connected between the upper cover and the lower cover, an upper disc and a lower disc being fixed on the rotating shaft, at least four groups of clamping assemblies being distributed in a circular array between the two discs, the clamping assembly being composed of two guide rods, an upper slide seat slidably mounted on the two guide rods and a lower slide seat slidably mounted on the two guide rods, the two guide rods being vertically fixed to The cam is secured to the upper and lower surfaces of the drive shafts and is adapted to engage with the guide rails when the cam is in engagement with the guide rails, and the cams are secured to the lower and upper surfaces of the drive shafts when the cams are engaged.

[0005] The utility model can be installed at the feed end of the fabric heat setting equipment, and a number of guide rollers are set to guide the fabric into the utility model and guide the wrinkle-removed fabric out. The two flattening modules are located on both sides of the fabric, and the fabric passes between the upper and lower pressure plates, passing through the wide area and the narrow area. When in the wide area, the upper slide and the lower slide are respectively abutted against the upper pressure ring and the lower pressure ring under the push of the reset spring. At this time, the distance between the upper and lower pressure plates is the largest, and there is no clamping effect on the fabric; in the narrow area, the upper and lower pressure plates tend to abut against each other, thereby producing a certain degree of clamping effect on the fabric. Since the fabric is always in a translation state under the drive of the transmission component, the friction between the fabric and the two pressure plates will drive the clamping components, the upper disc and the lower disc to rotate synchronously. Therefore, the clamping components on the two flattening modules will continuously rotate from the wide area to the narrow area, and the clamping components in the narrow area will return to the wide area. During the rotation process, the clamping parts of the upper and lower pressing plates on the fabric will move outward, so the friction force will pull the fabric to flatten it to both sides, thereby achieving the effect of flattening and removing wrinkles on the fabric.

[0006] Furthermore, the starting point of the narrow zone is located on the connecting line between the two rotating shafts, and the curvature of the narrow zone is between 0.2π and 0.4π. Only when the clamping starting position of the upper and lower pressure plates is located in the area behind the connecting line between the two rotating shafts will the clamping part always produce an outward pulling effect. However, as the angle of the clamping part's backward rotation increases, the clamping part's radial movement speed will gradually slow down. This will cause the clamping part to generate friction on the fabric in the opposite direction of movement, which will affect the fabric's smoothness. Therefore, the curvature of the narrow zone in the present invention is set to be less than 0.5π.

[0007] Furthermore, the upper slide is provided with an upper roller that rolls against the upper pressure ring, and the lower slide is provided with a lower roller that rolls against the lower pressure ring. By providing the rollers, the friction between the upper and lower slides and the corresponding pressure rings can be greatly reduced, reducing wear between the components.

[0008] Furthermore, the upper platen is secured with an upper core shaft that faces upward and rotatably engages with the upper slide. Several raised rubber particles are provided on the pressing surface of the upper platen. A lower platen is secured with a lower core shaft that faces downward and rotatably engages with the lower slide. Several raised rubber particles are also provided on the pressing surface of the lower platen. The provision of rubber particles on both platens significantly reduces the contact area with the fabric, thereby reducing friction and minimizing the extent of localized fabric deformation.

[0009] Therefore, compared with the existing technology, the present invention has the following characteristics: 1. The movement of the fabric will drive the several clamping components on the present invention to rotate continuously and synchronously. During the rotation process, the clamping parts of the upper pressure plate and the lower pressure plate on the fabric will have the effect of moving outward, so the friction force will pull the fabric to be flattened to both sides, thereby achieving the effect of flattening and removing wrinkles on the fabric. At the same time, the present invention does not require a power source and has a more streamlined structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Example 1: See Figure 1 、 Figure 3 and Figure 4The two guide rods are fixed vertically between the two discs, and an upper pressure plate 271 is provided on the upper slide seat and is rotatable, and a lower pressure plate 281 is provided on the lower slide seat and is rotatable. The two pressure plates are arranged in a mirror image with respect to the bracket; the flattening module includes an upper cover 210, a lower cover 220 and a rotating shaft 230 connected vertically and rotatably between the upper cover and the lower cover, and an upper disc 240 and a lower disc 250 are fixed on the rotating shaft. Ten groups of clamping assemblies are distributed in a circumferential array between the two discs. The clamping assembly consists of two guide rods 260, an upper slide seat 270 slidably assembled on the two guide rods, and a lower slide seat 280 slidably assembled on the two guide rods. Linear bearings are provided at the matching parts of the two slide seats and the guide rods. The two guide rods are vertically fixed between the two discs. An upper pressure plate 271 is provided on the upper slide seat and is rotatable, and a lower pressure plate 281 is provided on the lower slide seat and is rotatable. The two pressure plates are arranged vertically opposite to each other, and a return spring 290 is also provided between the upper slide seat and the lower slide seat (see Figure 5 ), the bottom surface of the upper cover is provided with an upper pressure ring 211 coaxial with the rotating shaft, and the top surface of the lower cover is provided with a lower pressure ring 221 coaxial with the rotating shaft. The upper pressure ring abuts against the upper side of the upper slide, and the lower pressure ring abuts against the lower side of the lower slide. The spacing between the two pressure rings has a wide area 10 and a narrow area 20. When the clamping assembly is located in the narrow area, the corresponding two pressure plates are set close to each other. The starting end of the narrow area is located on the connecting line of the two rotating shafts, and the curvature of the narrow area is about 0.25π (see Figure 2 ).

[0019] This embodiment can be installed at the feed end of a fabric heat setting device, and a number of guide rollers are provided to guide the fabric into this embodiment and guide the wrinkle-removed fabric out. Two flattening modules are located on either side of the fabric, and the fabric passes between the upper and lower pressure plates, passing through wide and narrow areas. When in the wide area, the upper and lower slides, driven by the return springs, respectively abut against the upper and lower pressure rings. At this time, the distance between the upper and lower pressure plates is at its maximum, and no clamping effect is produced on the fabric. In the narrow area, the upper and lower pressure plates tend to abut against each other, thus producing a certain degree of clamping effect on the fabric. Since the fabric is in a constant translational state driven by the transmission assembly, the friction between the fabric and the two pressure plates drives the clamping assembly, the upper disc, and the lower disc to rotate synchronously. Therefore, the clamping assembly on the two flattening modules continuously rotates from the wide area to the narrow area, and the clamping assembly in the narrow area returns to the wide area. During the rotation process, the clamping parts of the upper and lower pressing plates on the fabric will move outward, so the friction force will pull the fabric to flatten it to both sides, thereby achieving the effect of flattening and removing wrinkles on the fabric.

[0020] See Figure 5 and Figure 6 The upper slide is provided with an upper roller 272 that rolls against the upper pressure ring, and the lower slide is provided with a lower roller 282 that rolls against the lower pressure ring. By arranging the rollers, the friction between the upper and lower slides and the corresponding pressure rings can be greatly reduced, reducing the wear between the components.

[0021] See Figure 5 The upper platen is secured with an upper core shaft 273, which faces upward and rotates with the upper slide. Several raised rubber particles 274 are located on its pressing surface. A lower core shaft 283, which faces downward and rotates with the lower slide, is secured with the lower platen. Several raised rubber particles are also located on its pressing surface. The presence of rubber particles on both platens significantly reduces the contact area with the fabric, thereby reducing friction and minimizing localized fabric deformation.

[0022] See Figure 3 Two positioning frames 110 are provided at both ends of the bracket. The positioning frames are composed of a connecting seat 111, an upper connecting rod 112 and a lower connecting rod 113. The upper cover is fixed on the upper connecting rod, and the lower cover is fixed on the lower connecting rod.

[0023] It is obvious to those skilled in the art that the present invention can be modified in many ways, and such modifications are not considered to depart from the scope of the present invention. All such modifications obvious to those skilled in the art are intended to be included within the scope of the present claims.
