Description

Technical Field

[0001] This utility model relates to the technical field of fabric processing equipment, and in particular to a smoothing and winding device for composite fabrics. Background Technology

[0002] In the textile processing industry, composite fabrics, due to their multi-layered composite structure, are prone to surface wrinkles during the winding process due to uneven stress distribution, directly affecting the quality of the finished product. Traditional winding devices mostly use a mechanical structure combining guide rollers and pressure rollers, but they have the following technical defects: First, the fabric lacks a progressive tension adjustment mechanism in the conveying path, resulting in wrinkles remaining after initial guidance; second, rigid guide components are prone to friction damage when in contact with high-speed moving fabric, especially for functional composite fabrics with coatings, surface scratches will significantly reduce the product grade; third, the passive pressing mechanism in the winding stage cannot dynamically adapt to changes in roll diameter. As the roll diameter increases, the contact pressure between the traditional fixed pressure roller and the roll surface gradually becomes unbalanced, easily causing excessive stretching of the inner layer material or relaxation of the outer layer, forming "heart-shaped rolls" or "star-shaped rolls" defects.

[0003] Existing technologies such as CN209456008U propose a winding device with an elastic pressure roller, but its tension control relies on a single spring mechanism, making it difficult to achieve three-dimensional smoothing during the fabric unfolding stage. CN211310486U uses a multi-group guide roller array layout, which can improve surface smoothness, but the complex structure increases equipment maintenance costs and cannot solve the problem of pressure attenuation in the later stages of winding. In addition, traditional devices generally use a right-angle guide structure at the fabric inlet, which easily causes wear on the fabric edges under high-speed operation. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a smoothing and winding device for composite fabrics. The convex arc surface of the arc plate makes the fabric unfold in a transverse parabolic shape, which effectively eliminates longitudinal wrinkles and avoids transverse stress concentration. The smoothing roller can adaptively retreat as the winding diameter increases, maintaining the linear constant pressure on the pressing surface, and ensuring that the overall surface of the fabric is flat and the winding is stable.

[0006] To achieve the above objectives, this utility model proposes a smoothing and winding device for composite fabrics, comprising a base plate, a guide roller, a smoothing guide assembly, and a winding assembly. The base plate has a support frame on its top wall, and the guide roller is mounted on the support frame.

The fixed frame is mounted on the base plate; the conveying roller is mounted on the fixed frame; the smoothing mechanism is mounted on the fixed frame; and the winding assembly is mounted on the base plate.

[0007] The composite fabric smoothing and winding device of this utility model has a convex arc surface of the arc plate that makes the fabric unfold in a horizontal parabolic shape, which effectively eliminates longitudinal wrinkles and avoids lateral stress concentration. The smoothing roller can adaptively retreat as the winding diameter increases, maintaining the linear constant pressure on the pressing surface and ensuring that the overall surface of the fabric is flat and the winding is stable.

[0008] In addition, the smoothing and winding device for composite fabrics proposed in the above application may also have the following additional technical features:

[0009] Specifically, the smoothing mechanism includes an outer frame, rounded corners, and an arc-shaped plate, wherein the outer frame is mounted on the fixed frame; the rounded corners are located at the feed inlet of the outer frame; and the arc-shaped plate is located on the top wall of the inner cavity of the outer frame.

[0010] Specifically, the winding assembly includes a positioning bracket, a winding roller, and a driven smoothing mechanism. The positioning bracket includes a fixed bracket and a movable bracket. The fixed bracket is disposed on the base plate, and the movable bracket is movably disposed on the base plate. The winding roller is detachably disposed on the fixed bracket and the movable bracket. The driven smoothing mechanism is disposed on the fixed bracket and the movable bracket.

[0011] Specifically, the driven smoothing mechanism includes a moving block, a smoothing roller, and a reset component, wherein the moving block is movably mounted on the positioning bracket; the smoothing roller is mounted on the moving block; and the two ends of the reset component are respectively connected to the positioning bracket and the moving block.

Detailed Implementation

[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the appended spirit and connotation.

[0020] The following description, in conjunction with the accompanying drawings, describes a smoothing and winding device for composite fabrics according to an embodiment of the present invention.

[0021] like Figure 1-3 As shown, the composite fabric smoothing and winding device of this utility model embodiment includes a base plate 10, a guide roller 20, a smoothing guide component 30, and a winding component 40.

[0022] The bottom plate 10 has a support frame on its top wall, and the guide roller 20 is mounted on the support frame.

[0023] It should be noted that since the support frame is installed on the top wall of the base plate 10, the guide roller 20 is installed near the top wall of the support frame. The fabric is conveyed by the guide roller 20 during the conveying process.

[0024] The smoothing guide assembly 30 is mounted on the base plate 10. The smoothing guide assembly 30 includes a fixed frame 301, a conveying roller 302, and a smoothing mechanism 303.

[0025] The fixed frame 301 is mounted on the base plate 10, the conveying roller 302 is mounted on the fixed frame 301, the smoothing mechanism 303 is mounted on the fixed frame 301, and the winding assembly 40 is mounted on the base plate 10.

[0026] It should be noted that the height of the conveying roller 302 described in this embodiment is lower than that of the guide roller 20, while the smoothing mechanism 303 is located obliquely above the conveying roller 302. During the conveying process, the fabric passes through the guide roller 20 and the conveying roller 302 in sequence and enters the smoothing mechanism 303, and finally completes the winding on the winding assembly 40.

[0027] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the smoothing mechanism 303 includes an outer frame 3031, rounded corners 3032, and an arc plate 3033.

[0028] The outer frame 3031 is mounted on the fixed frame 301, the rounded corner 3032 is mounted at the feed inlet of the outer frame 3031, and the arc plate 3033 is mounted on the top wall of the inner cavity of the outer frame 3031.

[0029] It should be noted that the inner walls on both the upper and lower sides of the inlet of the outer frame 3031 are respectively provided with rounded corners 3032, and the arc-shaped plate 3033 is located near the outlet of the outer frame 3031. Therefore, when the fabric enters the outer frame 3031 during conveying, the wear on the fabric surface is effectively reduced. Subsequently, the fabric passes through the arc-shaped plate 3033, which smooths the fabric and removes wrinkles.

[0030] Furthermore, the curvature of the surface of the curved plate 3033 is set according to actual needs, so that the fabric passes through the surface of the curved plate 3033 and is convex in the middle and gradually curved on both sides, so that the surface of the fabric has tension when it passes through, and the fabric opens and smooths out.

[0031] In one embodiment of this utility model, such as Figure 1 As shown, the winding assembly 40 includes a positioning bracket 401, a winding roller 402, and a driven smoothing mechanism 403.

[0032] The positioning bracket 401 includes a fixed bracket and a movable bracket. The fixed bracket is mounted on the base plate 10, and the movable bracket is movably mounted on the base plate 10. The winding roller 402 is detachably mounted on the fixed bracket and the movable bracket, and the driven smoothing mechanism 403 is mounted on the fixed bracket and the movable bracket.

[0033] It should be noted that the fixed bracket and the movable bracket are respectively set on the same Y-axis of the base plate 10. The fixed bracket and the movable bracket are respectively provided with a locking rod through the bearing, and the take-up roller 402 is provided with a locking groove at both ends, so as to ensure that the take-up roller 402 can be disassembled and rotated after assembly.

[0034] Furthermore, a drive component is provided on the fixed bracket. The drive component is a stepper motor. By connecting the drive component to the power supply through the control switch, the take-up roller 402 is driven to rotate and take up the fabric.

[0035] It should be noted that, in order to ensure that the fabric is fully attached to the surface of the curved plate 3033 during the conveying process, the height of the take-up roller 402 and the angle between it and the outer frame 3031 are set according to actual needs.

[0036] In one embodiment of this utility model, such as Figure 1 As shown, the driven smoothing mechanism 403 includes a moving block 4031, a smoothing roller 4032, and a reset component 4033.

[0037] The movable block 4031 is movably mounted on the positioning bracket 401, the smoothing roller 4032 is mounted on the movable block 4031, and the two ends of the reset component 4033 are respectively connected to the positioning bracket 401 and the movable block 4031.

[0038] It should be noted that a sliding groove is provided on the movable support, the movable block 4031 slides in the sliding groove and the smoothing roller 4032 moves with the movable block 4031, and the reset component 4033 is a reset spring, which drives the movable block 4031 to reset.

[0039] Specifically, the steps for smoothing and winding the composite fabric are as follows: When the fabric is finished and undergoing final winding, the fabric passes through the guide roller 20, the conveyor roller 302 and enters the smoothing mechanism 303 in sequence. The fabric enters the outer frame 3031 and the rounded corners 3032 reduce wear on the fabric. Then the fabric passes through the arc plate 3033. The tension on the surface of the arc plate 3033 expands the fabric surface, thereby stretching the fabric and reducing wrinkles on the fabric surface. Then the fabric is wound on the winding assembly 40. The running drive component drives the winding roller 402 to rotate. During the winding process, the fabric passes through the driven smoothing mechanism 403 again. As the fabric is wound, the smoothing roller 4032 presses the surface of the fabric, making the fabric tightly adhere to the winding roller 402 and reducing the appearance of wrinkles on the fabric surface.

[0040] In summary, the smoothing and winding device for composite fabrics in this embodiment of the present invention uses the convex arc surface of the arc plate to make the fabric unfold in a transverse parabolic shape, which effectively eliminates longitudinal wrinkles while avoiding transverse stress concentration. The smoothing roller can adaptively retreat as the winding diameter increases, maintaining the linear constant pressure on the pressing surface and ensuring that the overall surface of the fabric is flat and the winding is stable.

[0041] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
