Description

Technical Field

[0001] This utility model relates to the field of elastic fabric processing technology, specifically to an anti-slip fabric laying device suitable for elastic fabrics. Background Technology

[0002] Elastic fabrics are widely used in clothing, home textiles and other fields due to their excellent stretchability and fit. However, during the fabric laying process, problems such as conveyor deviation and electrostatic adsorption can easily lead to wrinkles, roller sticking and inaccurate positioning, which affect the accuracy of subsequent cutting and sewing and the quality of finished products. Therefore, a special anti-slip fabric laying device for elastic fabrics is needed to achieve efficient and stable fabric laying.

[0003] In existing technologies, elastic fabric laying devices often suffer from two core problems: conveying misalignment and electrostatic adsorption. Traditional devices use fixed-width conveying rollers with simple clamping structures. Due to the lack of dynamic limiting mechanisms during conveying, the elastic fabric is prone to lateral misalignment or longitudinal stretching, resulting in wrinkles. At the same time, the static electricity generated by the friction between the fabric and the conveying rollers can adhere to the rollers or adjacent components, causing fabric adhesion, unevenness, or even secondary wrinkles during laying. More specifically, fixed rollers cannot adapt to fabrics of different widths, and adjustments require manual intervention with low precision. Rigid clamping structures are prone to damaging the fabric or uneven clamping force, exacerbating laying defects. These problems not only reduce production efficiency and increase the defect rate but also limit the application of elastic fabrics in high-end customization, sportswear, and other scenarios with extremely high requirements for laying precision, becoming a key pain point for industry technology upgrades. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide an anti-slip fabric laying device suitable for elastic fabrics, so as to solve the problem of low laying accuracy caused by transmission offset and electrostatic adsorption in the existing elastic fabric laying devices.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an anti-slip fabric laying device suitable for elastic fabrics, comprising a first mounting frame, a fabric roll for rolling up and unrolling elastic fabric on the first mounting frame, an unwinding device for guiding and conveying the rolled elastic fabric on the first mounting frame, and an adjusting conveying roller for limiting the fabric conveyed on the unwinding device on the first mounting frame. An auxiliary fabric-laying mechanism for laying the fed elastic fabric is provided on the side of the first mounting frame. The auxiliary fabric-laying mechanism includes a second mounting frame. Two movable frames are movably arranged on the second mounting frame. A movable frame is movably arranged in each movable frame. A support plate for supporting the elastic fabric is fixed at the bottom of the movable frame. A movable plate is also movably arranged in the movable frame. When the elastic fabric is on the support plate, the movable plate slides in the movable frame, and the bottom of the movable plate contacts the elastic fabric. Preferably, the auxiliary fabric laying mechanism includes two movable blocks that slide in the second mounting frame, and the top of each movable block is fixedly connected to the bottom of one of the movable frames. The second mounting bracket is provided with a first limiting groove for the movable block to slide; Preferably, the second mounting bracket is provided with a first motor, and a bidirectional screw is driven to the output shaft of the first motor through a coupling. Two movable blocks are symmetrically arranged outside the bidirectional screw, and both movable blocks are threadedly connected to the bidirectional screw. When the bidirectional screw rotates, the two movable blocks move relative to each other or away from each other under the limitation of the first limiting groove; Preferably, a second motor is provided in the movable frame, and a threaded rod is drivenly connected to the output shaft of the second motor, and the movable frame is threadedly connected to the threaded rod; When the threaded rod rotates, the movable frame is in a movable state within the movable frame; A connecting plate is provided in the movable frame, and a slot is provided on the movable frame for the connecting plate to pass through; Preferably, the top of the movable frame is provided with a mounting base, and a telescopic rod is embedded in the mounting base. The output end of the telescopic rod is fixedly connected to the top of the movable plate. The movable frame is provided with a second limiting groove, and the movable plate is slidably disposed inside the second limiting groove; The support plate and the movable plate are both provided with soft pads on their opposite surfaces; Preferably, the first mounting frame is provided with an electrostatic elimination component for eliminating static electricity of the elastic fabric guided and conveyed by the unwinding equipment. The electrostatic elimination component includes an ion fan, an air outlet pipe is fixed to the air outlet end of the ion fan, and an ion nozzle is fixed to the side of the air outlet pipe away from the ion fan, with the ion nozzle facing the elastic fabric. Preferably, a panel is provided on the side of the adjusting conveyor roller, and the ion nozzle is provided on the ion nozzle; The position of the panel changes as the position of the adjusting conveyor roller changes.

[0006] In summary, the present invention has the following main advantages: 1. This utility model combines the dynamic limiting function of the adjustable conveyor roller to suppress lateral deviation or longitudinal stretching of the elastic fabric in the conveying path, avoiding wrinkles or positional shifts caused by the fabric's elasticity. The auxiliary fabric laying mechanism adapts to fabrics of different widths through adjustable movable frame spacing. Combined with the soft padding clamping design of the support plate and movable plate, stable clamping points are formed at the ends of the fabric, ensuring that the portion of the fabric away from the clamping side can naturally lie flat on the surface of the second mounting frame during laying. The combination of mechanical limiting and the physical properties of the elastic fabric (such as gravity sag and stretchability) achieves full-process anti-slip control from conveying and limiting to flat laying, effectively improving the flatness and positioning accuracy of the fabric.

[0007] 2. The ion blower in this invention blows ionized air onto the surface of the elastic fabric during transport via ion nozzles. This utilizes electrostatic neutralization to eliminate static electricity generated by friction, directly reducing problems such as fabric adhesion to the conveyor rollers and uneven fabric laying caused by electrostatic adsorption. The panel's design dynamically adjusts with the position of the conveyor rollers, ensuring that the ion nozzles are always aligned with the fabric transport path, achieving dynamic static elimination throughout the entire process. This synergistic effect of static elimination and anti-slip fabric laying not only reduces slippage or adhesion caused by electrostatic adsorption but also further enhances the overall stability of the fabric laying by eliminating the interference of static electricity on the fabric's flatness.

[0010] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0011] The embodiments of this utility model will be described below based on its overall structure.

[0012] Please refer to Example 1 Figures 1-5 This utility model provides a technical solution: an anti-slip fabric laying device suitable for elastic fabrics, including a first mounting frame 11, a fabric roll 12 for rolling and unrolling elastic fabric on the first mounting frame 11, an unwinding device 13 for guiding and conveying the rolled elastic fabric on the first mounting frame 11, and an adjusting conveying roller 14 for limiting the fabric conveyed on the unwinding device 13 on the first mounting frame 11; the fabric roll 12 achieves precise release of fabric through axial rotation, and the conveying path is controlled by the guide roller group structure of the unwinding device 13; the adjusting conveying roller 14 dynamically adapts to the fabric thickness through an adjustable bracket, and the three work together to ensure a smooth and non-deviation-free conveying process, providing a stable foundation for anti-slip laying of elastic fabrics; An auxiliary fabric laying mechanism 2 for laying the elastic fabric is provided on the side of the first mounting frame 11. The auxiliary fabric laying mechanism 2 includes a second mounting frame 21, on which two movable frames 22 are movably mounted. Each movable frame 22 contains a movable frame 23. The bottom of the movable frame 23 is fixed with a support plate 24 for supporting the elastic fabric. A movable plate 25 is also movably mounted in the movable frame 23. The movable frame 22 and the movable frame 23 are coordinated with the support plate 24 to form an adjustable fabric support structure. Combined with the sliding clamping function of the movable plate 25, the elastic fabric is stably supported and fixed at the end during the laying process, improving the flatness of the fabric. When the elastic fabric is on the support plate 24, the movable plate 25 slides in the movable frame 23, and the bottom of the movable plate 25 contacts the elastic fabric. The movable plate 25 forms a soft pad clamp with the support plate 24 by sliding, and uses friction to fix the end of the fabric, ensuring that the part of the fabric away from the clamping side is naturally flat when laid out, avoiding wrinkles or displacement, and enhancing the anti-slip effect. Furthermore, the auxiliary fabric laying mechanism 2 includes two movable blocks 263 that slide in the second mounting frame 21. The top of each movable block 263 is fixedly connected to the bottom of one of the movable frames 22. The second mounting frame 21 is provided with a first limiting groove 264 for the movable blocks 263 to slide. The cooperation between the movable blocks 263 and the first limiting groove 264 enables precise adjustment of the spacing between the movable frames 22, adapting to elastic fabrics of different widths, improving the adaptability of the device, and ensuring that the fabric laying process covers the entire width of the fabric. Furthermore, a first motor 261 is provided in the second mounting bracket 21. A bidirectional screw 262 is connected to the output shaft of the first motor 261 via a coupling. Two movable blocks 263 are symmetrically arranged outside the bidirectional screw 262, and both movable blocks 263 are threadedly connected to the bidirectional screw 262. When the bidirectional screw 262 rotates, the two movable blocks 263 move relative to or away from each other under the limit of the first limiting groove 264. The first motor 261 drives the bidirectional screw 262 to rotate, and drives the movable blocks 263 to move synchronously through the threaded connection, thereby realizing the automatic adjustment of the spacing of the movable frame 22 and improving the operating efficiency and adjustment accuracy. Furthermore, a second motor 271 is installed in the movable frame 22, and a threaded rod 272 is driven and connected to the output shaft of the second motor 271. The movable frame 23 is threadedly connected to the threaded rod 272. When the threaded rod 272 rotates, the movable frame 23 is in a movable state within the movable frame 22. A connecting plate 273 is installed in the movable frame 22, and a slot is provided on the movable frame 23 for the connecting plate 273 to pass through. The second motor 271 drives the threaded rod 272 to rotate, causing the movable frame 23 to move precisely within the movable frame 22. The design of the slot through the connecting plate 273 ensures the stability of the movement of the movable frame 23 and achieves efficient adjustment of the fabric clamping position. Furthermore, a mounting base 281 is provided at the top of the movable frame 23, and a telescopic rod 282 is embedded in the mounting base 281. The output end of the telescopic rod 282 is fixedly connected to the top of the movable plate 25. A second limiting groove 283 is provided on the movable frame 23, and the movable plate 25 is slidably disposed inside the second limiting groove 283. Soft pads are provided on the opposing surfaces of the support plate 24 and the movable plate 25. The telescopic rod 282 drives the movable plate 25 to slide along the second limiting groove 283, which, together with the soft pads, achieves fabric clamping without damage, ensuring that the clamping force is controllable and uniform, and improving the anti-slip performance and surface quality of the fabric during the laying process.

[0013] Please refer to Example 2 Figure 6 Furthermore, in conjunction with Embodiment 1, the first mounting frame 11 is provided with an electrostatic elimination component 3 for eliminating static electricity on the elastic fabric guided and conveyed by the unwinding device 13. The electrostatic elimination component 3 includes an ion fan 31, an air outlet pipe 32 is fixed to the air outlet end of the ion fan 31, and an ion nozzle 34 is fixed to the side of the air outlet pipe 32 away from the ion fan 31, with the ion nozzle 34 facing the elastic fabric. The ion fan 31 blows ion air onto the fabric surface through the air outlet pipe 32 and the ion nozzle 34 to neutralize the static electricity generated during the conveying process, reduce unevenness or adhesion caused by static adsorption, and improve the anti-slip fabric laying effect. Furthermore, a panel 33 is provided on the side of the adjusting conveyor roller 14, and an ion nozzle 34 is provided on the ion nozzle 34; the position of the panel 33 changes with the position of the adjusting conveyor roller 14; the panel 33 moves synchronously with the adjusting conveyor roller 14 to ensure that the ion nozzle 34 is always aligned with the fabric conveying path, realize dynamic static elimination, ensure the static control effect of the whole process, and enhance the stability of fabric laying.

[0014] The working process of this anti-slip fabric laying device for elastic fabrics is as follows: When the device is started, the elastic fabric is initially wound onto the roll 12 of the first mounting frame 11. The roll-up and unrolling of the fabric is achieved by the rotation of the roll 12. This is a common fabric roll-up and unrolling structure in the prior art. The release of the fabric is controlled by axial rotation. The released fabric is guided and conveyed by the unwinding device 13. The unwinding device 13 adopts a guide roller structure. The fabric conveying path is controlled by the pressure between the rollers and the conveying direction to ensure that the conveying process is smooth and without deviation. This is a conventional design for fabric conveying guidance in the prior art. During the conveying process, the adjustable conveying roller 14 limits the fabric. The adjustable conveying roller 14 is connected to the first mounting frame 11 through an adjustable bracket. The roller spacing can be adjusted according to the fabric thickness or conveying requirements to achieve dynamic limiting of the fabric in the conveying path and prevent the fabric from deviating or wrinkling. This is a typical design for conveying limitation in the prior art. The auxiliary fabric laying mechanism 2 on the side of the first mounting frame 11 starts working. When the first motor 261 drives the bidirectional screw 262 to rotate, the movable block 263 on the second mounting frame 21 drives the two movable frames 22 to move relative to or away from each other through the limiting action of the first limiting groove 264, thereby adjusting the spacing between the movable frames 22 to accommodate elastic fabrics of different widths. Subsequently, the second motor 271 inside the movable frame 22 drives the threaded rod 272 to rotate, causing the movable frame 23 to move within the movable frame 22, adjusting the movable frame 23. Position 3; When the elastic fabric is conveyed to the support plate 24, the movable plate 25 slides in the second limit groove 283 driven by the telescopic rod 282. The soft pad on the opposite side of the movable plate 25 contacts the fabric, and the fabric is clamped by the friction of the soft pad. After clamping, the position of the movable frame 23 is adjusted, and the elastic fabric is laid on the second mounting frame 21. Then the unwinding device 13 is turned off. With the assistance of the adjusting conveyor roller 14, the other side of the elastic fabric is clamped to complete the laying action. During this process, the static elimination component 3 works synchronously. The ion air generated by the ion fan 31 is delivered to the ion nozzle 34 through the air outlet duct 32. The ion nozzle 34 is directed towards the elastic fabric being conveyed, and the static electricity on the fabric surface is eliminated through the static neutralization effect of the ion air. The position of the panel 33 changes with the position of the adjustable conveyor roller 14 to ensure that the ion nozzle 34 is always aligned with the fabric conveying path, thereby achieving dynamic static elimination. The elimination of static electricity directly reduces problems such as uneven fabric laying and adhesion to the conveyor roller caused by static adsorption of the elastic fabric, and improves the anti-slip performance and flatness during fabric laying. In the entire workflow, each component is driven by a motor and linked with the mechanical structure to realize the full automation of the elastic fabric from rolling, conveying, limiting, clamping to laying. At the same time, the static elimination component 3 ensures the stability of the conveying process.
