Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically a wide-width edge-sealing mechanism for fabric processing. Background Technology

[0002] Wide-width fabrics, such as tarpaulins, advertising banners, geotextiles, and various industrial textiles, play an important role in modern industrial and commercial applications. In the final stage of production and processing, the edges of these fabrics must be effectively sealed to prevent the warp and weft threads from unraveling, ensuring the durability, aesthetics, and functional integrity (such as waterproofing and dustproofing) of the product.

[0003] Referring to the patent document: Patent Publication No. CN220619581U, Patent Publication Date 2024-03-19, a cutting mechanism for textile fabric is disclosed, including a platform. Two support feet are provided on each of the left and right sides of the bottom of the platform. A U-shaped plate is provided on the top of the platform, and columns are provided on each of the left and right sides of the top of the U-shaped plate. A horizontal plate is provided on the top of the left column, with one end fixedly connected to the top of the right column. This cutting mechanism for textile fabric works by placing the textile fabric on the top of the platform, above the strip-shaped holes, and then activating a first servo motor to move the frame downwards, causing two pressure plates to press the edges of the fabric. Subsequently, a dual-axis servo motor is activated to move the two pressure plates in opposite directions, thereby keeping the fabric taut. This prevents the fabric from becoming too loose, which could lead to slanted edges during cutting, thus achieving a good cutting effect.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:

[0005] Traditional edge sealing of wide fabrics is mainly done in two ways: one is traditional sewing, which involves using an industrial sewing machine to sew the edge strip to the edge of the fabric. While this method can ensure a strong connection, it can puncture the fabric itself, creating pinholes and compromising the material's integrity. For applications requiring waterproofing and sealing, this leaves a potential risk of leakage, and the processing efficiency is relatively low. The other method is mass production through heat fusion edge sealing, such as using a hot air welding gun or heated blade to directly heat and melt the fabric edge. While this method can achieve a seamless seal, the original edges of the fabric often have burrs and irregular threads. Direct heat fusion edge sealing can result in uneven and weak edge sealing, affecting the quality of the finished product. Furthermore, when facing the demand for mass production of fabrics of different widths, most existing edge sealing equipment requires manual adjustment of the edge sealing device's position or replacement of equipment, which is cumbersome and makes it difficult to ensure the uniformity of edge sealing width in mass production.

[0006] Therefore, this utility model provides a wide edge sealing mechanism for fabric processing. Utility Model Content

[0007] To address the problems of traditional wide-width fabric edge sealing processes, such as sewing damaging the fabric integrity, poor quality due to burrs in heat-sealing, and low efficiency and poor consistency due to the inability to quickly adapt to different widths, the purpose of this utility model is to provide a wide-width edge sealing mechanism for fabric processing.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a wide-width edge-sealing mechanism for fabric processing, comprising a frame, wherein a processing mechanism is provided in the middle of the frame for processing the edges of the original fabric, the processing mechanism comprising:

[0009] The edge sealing assembly includes an installation roller rotatably mounted on one side of the upper part of the frame, a winding roller rotatably mounted on the other side of the upper part of the frame, and three cooperating adjusting rollers rotatably mounted in the middle of the frame. Fabric is wound around the outside of the installation roller, the winding roller, and the adjusting rollers. Two symmetrically distributed movable plates are provided on the upper part of the adjusting rollers. A cutting blade is installed on one side of the upper part of each of the two movable plates, and a hot air welding gun is installed on the other side of each of the two movable plates.

[0010] An adjustment component, located on the upper part of the two movable plates, is used to adjust the relative position of the two movable plates.

[0011] Preferably, the adjustment assembly includes a rotating plate disposed in the middle of the two moving plates, with connecting rods mounted at both ends of the rotating plate via fisheye bearings, and the other ends of the two connecting rods mounted at the top center of the moving plate via fisheye bearings. A drive assembly is provided at the top center of the rotating plate.

[0012] Preferably, the drive assembly includes a drive motor disposed in the middle of the frame, and the top center of the rotating plate is fixedly mounted on the drive end of the drive motor.

[0013] Preferably, a collection box is provided at the lower part of each of the two moving plates, and the upper part of the two collection boxes is in contact with the outer surface of the adjusting roller.

[0014] Preferably, a protective cover is fixedly installed on the upper part of the frame, and the top of the drive motor is installed on the inner upper surface of the protective cover through a flange.

[0015] Preferably, two symmetrically distributed limiting rods are fixedly installed in the middle of the protective cover, and both ends of the two movable plates are slidably locked onto the outer surface of the limiting rods.

[0016] Beneficial effects

[0017] This utility model provides a wide-width edge-sealing mechanism for fabric processing. Compared with the prior art, it has the following advantages:

[0018] 1. During the conveying process of the fabric in this application, its two edges are first precisely cut by a high-speed steel cutting blade to effectively remove burrs and loose threads, forming a smooth initial edge. Subsequently, this edge enters the action area of ​​a hot air welding gun. The concentrated hot air released by the welding gun causes the edge of thermoplastic fabrics such as chemical fibers to melt rapidly and self-adhere. This continuous process of "cutting first and then sealing" not only prevents the warp and weft threads of the fabric edge from loosening, but also forms a strong sealed edge, significantly improving the integrity and aesthetics of the edge sealing. It also greatly improves the processing efficiency of the fabric edge sealing process.

[0019] 2. When processing fabrics of different widths, this application starts the drive motor and drives the rotating plate to rotate. The rotating plate converts the rotational motion into linear thrust through the connecting rods at both ends, driving the two moving plates to move synchronously towards or away from each other under the guidance of the limit rod. This allows the cutting blade and hot air welding gun mounted on the moving plate to move accordingly and automatically position themselves to the two edges of the current fabric. This enables rapid adjustment for fabrics of different widths, greatly enhancing the versatility, flexibility and automation of the equipment. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a wide edge-sealing mechanism for fabric processing, including a frame 1, with a processing mechanism 2 located in the middle of the frame 1 for processing the edges of the original fabric. The processing mechanism 2 includes:

[0027] The edge-sealing assembly 21 includes a mounting roller 211 rotatably mounted on one side of the upper part of the frame 1. Both ends of the mounting roller 211 are mounted on the frame 1 via deep groove ball bearings, used to install and fix the roller with the edge-sealing fabric 212 wound on it. A winding roller 213 is rotatably mounted on the other side of the upper part of the frame 1. Both ends of the winding roller 213 are also mounted on the frame 1 via deep groove ball bearings. The winding roller 213 is used to rewind the edge-sealed fabric 212 into a cylindrical shape, and the winding roller 213 is driven by a conventional servo motor. Three cooperating adjusting rollers 214 are rotatably mounted in the middle of the frame 1. Fabric 212 is wound around the outer sides of the mounting roller 211, the winding roller 213, and the adjusting rollers 214. 2. The upper part of the adjusting roller 214 is provided with two symmetrically distributed movable plates 215. A cutting blade 217 is installed on one side of the upper part of each movable plate 215. The cutting blade 217 is made of high-speed steel and is detachably connected to the movable plate 215 by bolts for easy replacement later. The cutting blade 217 can first remove burrs, threads and other defects on both sides of the fabric 212. A hot air welding gun 216 is installed on the other side of each movable plate 215. The temperature adjustment range of the hot air welding gun 216 is 50-650℃. The temperature can be adjusted according to the material of the fabric 212 (such as chemical fiber cloth, cotton and linen cloth). The air outlet of the hot air welding gun 216 contacts the edge of the fabric 212 to seal the edge of the cut fabric 212.

[0028] Adjustment component 22 is located on the upper part of the two movable plates 215 and is used to adjust the relative position of the two movable plates 215.

[0029] The adjustment assembly 22 includes a rotating plate 221 disposed in the middle of the two moving plates 215. Both ends of the rotating plate 221 are mounted with connecting rods 222 via fisheye bearings. The other ends of the two connecting rods 222 are mounted in the middle of the top of the moving plate 215 via fisheye bearings. A drive assembly is provided in the middle of the top of the rotating plate 221. With the rotation of the rotating plate 221, the two moving plates 215 can be driven to move synchronously relative to each other or in opposite directions under the transmission of the connecting rods 222. This allows the position of the cutting blade 217 and its hot air welding gun 216 to be adjusted according to the width of the fabric 212, so that they are always located at the two sides of the fabric 212.

[0030] The drive assembly includes a drive motor 223 located in the middle of the frame 1. The top center of the rotating plate 221 is fixedly mounted on the drive end of the drive motor 223. The drive motor 223 can be a three-phase asynchronous motor of model Y132S-4, which can drive the rotating plate 221 to rotate.

[0031] The lower part of each of the two moving plates 215 is provided with a collection box 218. The upper part of the two collection boxes 218 is in contact with the outer surface of the adjusting roller 214. The two collection boxes 218 are installed on both sides by snap-fit ​​to collect the debris generated during cutting.

[0032] A protective cover 219 is fixedly installed on the upper part of the frame 1, and the top of the drive motor 223 is installed on the inner upper surface of the protective cover 219 through a flange.

[0033] Two symmetrically distributed limiting rods 224 are fixedly installed in the middle of the protective cover 219. The two ends of the two movable plates 215 are slidably locked on the outer surface of the limiting rods 224. The two ends of the two movable plates 215 are slidably locked in the middle of the limiting rods 224 by means of linear bearings.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] During operation, the operator installs the roller wound with the original width of fabric 212 onto the mounting roller 211 on one side of the frame 1. Then, the end of the fabric 212 is led out and passed around the three adjusting rollers 214 in the middle of the frame 1 in a zigzag path, which effectively tensions and spreads the flat fabric 212. Finally, the end of the fabric 212 is fixed onto the winding roller 213 on the opposite side. After the threading is completed, the conventional servo motor driving the winding roller 213 provides stable traction power, so that the fabric 212 is continuously and smoothly conveyed from the mounting roller 211 to the winding roller 213. When the fabric 212 passes over the upper part of the adjusting roller 214, its two side edges pass exactly over two symmetrically distributed moving plates. Below 215, the cutting blade 217 and hot air welding gun 216 integrated on each moving plate 215 will perform operations in sequence. The cutting blade 217 first contacts the edge of the fabric 212 and removes irregular parts such as burrs and loose threads caused by cutting, forming a neat and smooth straight edge. The neat edge formed after cutting contacts the air outlet of the temperature-adjustable hot air welding gun 216. For fabric 212 made of thermoplastic materials such as chemical fibers, the hot air welding gun 216 releases high-temperature airflow, which will instantly melt the edge of the fabric 212. Under the action of surface tension and subsequent traction force, the molten fibers re-solidify and self-adhere, thereby forming a strong, sealed and pinhole-free smooth edge seal, effectively preventing the fabric edge from spreading.

[0036] When different widths of fabric 212 need to be processed, the drive motor 223 is started, and its output end drives the rotating plate 221 to rotate. The rotating plate 221 converts the rotational motion into linear motion through the connecting rods 222 (which use fisheye bearings to allow a certain angle of deflection) connected at both ends, thereby pushing or pulling the two moving plates 215. Under the constraint of the limit rod 224, the two moving plates 215 can only perform precise linear motion, realizing synchronous movement towards or away from each other. This allows the cutting blade 217 and hot air welding gun 216 mounted on the moving plate 215 to be quickly and accurately adjusted to the edge position that matches the current width of the fabric 212.
