AI Technical Summary
Existing textile fabric processing equipment cannot dynamically adjust the cutting speed and feed force according to the fabric thickness, resulting in low processing efficiency for thin fabrics, rough cut surfaces for thick fabrics, and problems such as tool entanglement or fiber damage.
The hydraulic oil flow rate is controlled by the magnetic repulsion between the electromagnetic block and the permanent magnet block, which adjusts the moving speed and feed force of the cutting tool. Combined with the use of tension rollers and micro motors, this ensures that the fabric remains taut during the cutting process, adapting to the needs of fabrics of different thicknesses.
It improves the efficiency and precision of fabric cutting, avoids rapid entanglement of thin fabrics and fiber damage of thick fabrics, ensures the flatness of the cut surface and the dimensional consistency of multi-layered fabrics, and enhances safety and processing quality.

Abstract
Description
Technical Field
[0001] This invention relates to the field of fabric cutting technology, and specifically to a cutting and binding device for textile fabric processing. Background Technology
[0002] In the textile fabric processing industry, the edge cutting and binding process is a crucial step in ensuring the neatness of the finished fabric edges and preventing fraying. Its processing precision and efficiency directly affect the stability of the fabric in subsequent sewing and use. The edge cutting and binding device for textile fabric processing is a specialized automated or semi-automated equipment applied to the finishing stage of textile fabrics. Its core function is to achieve fixed-length or fixed-shape cutting of the edges of textile fabrics (such as cotton, chemical fiber, knitted fabric, woven fabric, etc.) and waterproof sheet or roll materials (such as EPDM rubber waterproof rolls, PVC waterproof rolls, elastomer modified bitumen waterproof rolls, plastomeric modified bitumen waterproof rolls, self-adhesive rubber bitumen waterproof rolls, thermoplastic polyolefin waterproof rolls, sodium bentonite waterproof blankets) by integrating two core processes: fabric cutting and edge binding. At the same time, it completes edge binding, sewing or heat-pressing fixation treatment, ultimately solving problems such as easy fraying, pilling and fraying of fabric edges, while improving the fabric processing precision and the appearance of the finished product.
[0003] Chinese patent application CN111648118A discloses a fabric edge cutting device for textile processing, including a base plate. A first vertical plate and a second vertical plate are fixedly installed on the top of the base plate. A horizontal plate is installed on the top of the first and second vertical plates. A first groove and a second groove are formed at the bottom of the horizontal plate. A first screw rod is installed in the first groove, and a second screw rod is installed in the second groove. The threads of the first and second screw rods have opposite directions. This invention is reasonably designed, practical, and facilitates adjustment of the distance between the two cutters and their height. It is suitable for edge cutting fabrics of different thicknesses and widths, improving the quality and efficiency of fabric edge cutting. Furthermore, it can absorb and remove fabric scraps, wool threads, and dust generated during fabric edge cutting, improving the air quality of the working environment and ensuring the health of workers. Although this device can achieve fabric edge cutting, it still has significant shortcomings when dealing with thick waterproof materials such as elastomeric modified bitumen waterproof membranes and plastomeric modified bitumen waterproof membranes.
[0004] In real-world applications, the cutting speed and feed force of existing cutting mechanisms are mostly fixed values, unable to be dynamically adjusted according to fabric thickness. When cutting thin fabrics, the cutting speed cannot be appropriately increased, resulting in low processing efficiency. When cutting thick fabrics, the cutting speed cannot be appropriately reduced, leading to excessive force on the cutting tool, resulting in rough cut surfaces and fabric entanglement on the cutting tool. In existing technologies, reducing the feed speed when cutting thick fabrics increases the feed force of the cutting components. Since the fiber structure of thick fabrics (such as thick canvas and plush fabric) is more compact or fluffy, if the feed speed is reduced but the feed force remains high, the cutting tool will exert prolonged compression on local fibers. Furthermore, when batch cutting multiple layers of stacked thick fabrics, high feed force can easily cause lateral thrust between layers. Summary of the Invention
[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a cutting and binding device for textile fabric processing, which effectively solves the problem that existing technologies cannot dynamically adjust according to fabric thickness.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] The present invention provides a cutting and binding device for textile fabric processing, comprising: a transport mechanism, a tensioning mechanism provided on the transport mechanism, a winding device fixed on the transport mechanism on one side of the tensioning mechanism, and a cutting mechanism provided between the tensioning mechanism and the winding device;

Multiple hydraulic telescopic rods are symmetrically arranged on the two support frames, and a pressure frame is fixed to the telescopic end of each hydraulic telescopic rod.
[0009] Preferably, the tensioning mechanism includes multiple support columns 1 fixed to the support frame, and multiple support columns 2 fixed to the support frame on the side of the support columns 1 away from the L-shaped frame. The upper ends of the support columns 1 and 2 are bolted to a top cover. The lower ends of the top cover are symmetrically fixed with elastic springs. The elastic springs contain limiting telescopic columns fixed to the lower ends of the top cover. The lower ends of the limiting telescopic columns are fixed with movable blocks. Two movable blocks on the same side are rotatably connected with a drive roller. A micro motor is fixed on one of the two movable blocks on one side. The output end of the micro motor is fixedly connected to the drive roller.
[0010] Preferably, the plurality of movable blocks are slidably connected between two support columns one and support column two.
[0011] Preferably, the cutting mechanism includes two support plates fixed to a support frame. An electric telescopic rod is fixed to the upper end of the support plate. A fixed frame is fixed to the telescopic end of the electric telescopic rod. A movable slide rail is fixedly connected between the two fixed frames. An arc-shaped groove is formed in the middle of the movable slide rail near the fixed frame. A hydraulic telescopic column fixed to the fixed frame is provided in the arc-shaped groove. A movable frame is fixed to the telescopic end of the hydraulic telescopic column. The movable frame is slidably connected to the outer surface of the movable slide rail. One of the fixed frames is provided with a drive assembly. A cutting assembly is provided below the movable frame.
[0012] Preferably, the drive assembly includes a base fixed to a mounting frame, a liquid pump fixed to the upper end of the base, a sealed housing fixed to the lower end of the base, a U-shaped tube between the input end of the liquid pump and the sealed housing, the U-shaped tube connecting the input end of the liquid pump and the sealed housing, a connecting pipe fixed to the output end of the liquid pump, and an adjustment assembly between the connecting pipe and the mounting frame.
[0013] Preferably, the cutting assembly includes a sealing tube fixed to the connecting pipe, a fixing tube fixed inside the sealing tube, a plurality of adjustment holes arrayed on the outer surface of the fixing tube, a movable cover fitted on the outer surface of the fixing tube, an electromagnetic block fixed to one end of the fixing tube near the fixing frame, a permanent magnet fixed to the inner wall of the movable cover, the electromagnetic block and the permanent magnet repelling each other, a recycling tube penetrating the movable cover and the inner wall of the sealing tube fixed to one end of the sealing tube near the fixing frame, and a baffle fixed to the inner wall of the sealing tube.
[0014] Preferably, the cutting assembly includes a top plate fixed to the lower end of the movable frame, a cutting frame fixed to the lower end of the top plate, a cutting blade rotatably connected inside the cutting frame, a motor three fixed to the lower end of the top plate, a hydraulic telescopic rod two fixed to the output end of the motor three, a connecting ring connected to the outer surface of the hydraulic telescopic rod two, a cross rod fixed to the telescopic end of the hydraulic telescopic rod two, and a cross tube fixed to the end of the cutting blade near the motor three.
[0015] Preferably, the outer surface of the connecting ring is connected to a connecting pipe, and a hydraulic oil pumping device is provided between the connecting pipe and the plurality of hydraulic telescopic rods. The hydraulic telescopic rods, the hydraulic oil pumping device, and the connecting pipe are filled with hydraulic oil.
[0016] The technical solution provided by this invention has the following advantages compared with the known prior art:
[0017] First, by controlling the current flowing into the electromagnetic block, the repulsive force between the electromagnetic block and the permanent magnet can be used to control the sliding of the movable cover along the fixed tube, changing the opening and closing area of the adjustment hole. The current of the electromagnetic block is proportional to the thickness of the material (indirectly obtained through the moving distance of the clamping frame). When processing thin materials, the opening and closing area of the adjustment hole is small, the hydraulic oil flow rate is fast, and the cutting tool moves quickly, improving processing efficiency. When processing thick materials, the opening and closing area of the adjustment hole is large, the hydraulic oil flow rate is slow, the cutting tool moves slowly, and the feed force is stable, avoiding the problems of rough cutting surface and tool entanglement in thick materials. Furthermore, when dealing with thick fabrics, reducing the feed force weakens the pressure of the blade on the fabric, preventing uneven fiber breakage and increased burrs at the edges of thick fabrics. When cutting multi-layer fabrics, it can also make the force on each layer of fabric more uniform, reducing misalignment and displacement caused by excessive thrust between layers, and ensuring dimensional consistency of multi-layer cutting.
[0018] Secondly, by driving the tensioning roller to rotate in the opposite direction via a micro motor, friction can be used to pull the material. For thick materials, the tensioning roller can be driven to move down via an electric telescopic rod to further press and tighten it, ensuring that the fixed fabric is always in a taut state. This completely solves the problem of edge skewing caused by fabric slack during cutting, improves the flatness of the cut edge, and when the clamping frame moves down to fix the material, the hydraulic oil pumping device delivers hydraulic oil to the hydraulic telescopic rod through the connecting ring, driving the cross rod to move towards the cross tube. This ensures that the cutter will only be driven when the material is fixed, eliminating the safety hazard caused by accidental motor activation. Attached Figure Description

[0038] To further explain, the following settings are implemented to increase the safety of the device during operation, such as...

A cross rod 396 is fixed to the telescopic end of the hydraulic telescopic rod 394. A cross tube 397 is fixed to the end of the cutting blade 398 near the motor 393.
[0039] The working principle of this invention is as follows: The material to be edged is transported into the device by a continuous feeding device. The material is manually placed from below the tension roller 14 to above multiple transport rollers 15. At this time, the two elastic springs 24 will always generate a force to push the movable block 26 downward, so that the material is clamped by the drive roller 27 and the transport rollers 15. According to the thickness, width and preset edged specifications of the fabric to be processed, the operator adjusts the distance between the pressure frame 17 and the transport rollers 15 by controlling the hydraulic telescopic rods 16 symmetrically distributed on the two support frames 11. This adjustment method can flexibly adapt to different fabric thicknesses from thin gauze to thick canvas, avoiding the problem of thin fabrics being easy to shift and thick fabrics being easy to stretch due to the initial fixed distance. At the same time, the electric telescopic rod 13 fixed to the top wall of the open slot of the L-shaped frame 12 is adjusted to set the tension roller 14. The initial height of 4 ensures that the fabric is not excessively loose or tight when it enters the conveying stage. According to the cutting position requirements, control the electric telescopic rod 32 fixed on the support plate 31 and adjust the overall height of the fixing frame 33 so that the cutting component 39 and the fabric conveying path maintain a suitable vertical distance. At this time, it is only necessary to ensure that the motor 1 and the tensioning mechanism 2 on the support frame 11 are working properly to transport the material placed in the device. Start the motor 1 and motor 2 to drive the conveying roller 15 and the drive roller 27 to rotate respectively. This allows the material held by the drive roller 27 and the limiting telescopic column 25 to move towards one side of the cutting component 39. It should be noted that in order to transport the material better, the motor 1 and motor 2 need to drive the drive roller 27 and the conveying roller 15 to move in opposite directions until the material moves to the corresponding position.
[0040] The surface of the drive roller 27 is covered with resistance wires for heating and is wrapped with a rubber jacket. When dealing with thermoplastic fiber fabrics and composite fabrics, heating can prevent edge frizz and fraying, and make the cut smoother. If cold cutting is used, the fibers will be loose due to the lack of fixed points. Heating can melt and solidify the edge fibers to form a locking effect. Some fabrics (such as coated fabrics) have special textures. Cold cutting can easily lead to uneven cuts or coating peeling. Heating can make the cut surface smoother and more precise. There is a certain space between the two drive rollers 27. At this time, the fabric is in a stable transport state. By adding different devices, the process of the device can be further improved. However, it is best to use auxiliary operations related to the lamination process to make the process more coordinated and rigorous.
[0041] It should be noted that the drive roller 27 can adaptively conform to fabric surfaces of different thicknesses. Even if there are local thickness differences in the fabric (such as spliced fabrics), the elasticity of the spring 24 can compensate for this, ensuring that the drive roller 27 maintains constant pressure on the material surface. Under this pressure, the drive roller 27, in conjunction with its rotation, stretches and flattens the wrinkles on the fabric surface along the conveying direction, ensuring that the fabric is in a flat and stress-free state when it enters the cutting mechanism 3. This directly avoids problems such as discontinuous cutting edges and non-adherent binding caused by wrinkles, significantly improving the accuracy of subsequent processing. Before cutting and binding the material, the hydraulic oil pump device is activated to extract hydraulic oil from multiple hydraulic telescopic rods 16, causing the multiple hydraulic telescopic rods 16 to retract simultaneously, which can drive the fixed... The clamping frame 17 at the telescopic end of the hydraulic telescopic rod 16 moves downward to press down on the material and fix it. Before this, the motors 1 and 2 on the support frame 11 will automatically shut down and start the micro motor on the L-shaped frame 12. The micro motor will drive the tension roller 14 to rotate. The rotation direction of the tension roller 14 is opposite to the previous rotation direction of the drive roller 27. The friction between the tension roller 14 and the surface of the material pulls the material, so that the fixed material is always in a taut state. When dealing with thicker materials, the electric telescopic rod 13 can be activated to continue to drive the tension roller 14 to move downward. The downward movement of the tension roller 14 will generate force on the material, ensuring that the material remains flat during cutting to the greatest extent.
[0042] During the downward movement of the clamping frame 17, the hydraulic oil pumping device transports hydraulic oil through the connecting pipe and the connecting ring 395 to the hydraulic telescopic rod 394, causing the hydraulic telescopic rod 394 to extend and drive the cross rod 396 to move towards the cross tube 397 until the cross rod 396 is fully inside the cross tube 397. It should be noted that the cross rod 396 may not perfectly match the angle of the cross tube 397 during its movement, resulting in the cross rod 396 failing to move into the cross tube 397. However, during the material cutting process, the motor 393 can be started to drive the cross rod 396 to rotate through the hydraulic telescopic rod 394. The cross rod 396 itself has an elastic telescopic function, and it will automatically extend and retract when it cannot enter the cross tube 397. When the cross rod 396 is rotated by the motor 393, a suitable angle will always be reached so that the cross rod 396 enters the cross tube 397. At this time, the cross rod 396, which is in the retracted state, will return to its original position and enter the cross tube 397, allowing the motor 393 to resume its movement. The cutting tool 398 can be rotated to perform cutting work. That is to say, when the clamping frame 17 does not press down on the material, even if the motor 393 is accidentally activated, the cutting tool 398 will not rotate, ensuring the safety of the device during use. During the cutting process, the liquid pump 382 in the drive assembly 38 is activated. The liquid pump 382 draws hydraulic oil from the sealed box 383 through the U-shaped tube 384. Through the extension and retraction of the hydraulic telescopic column 36, the movable frame 37 is driven to slide along the movable slide rail 34, so that the cutting tool 398, which is in the process of rotation, moves along the movable slide rail 34 to complete the cutting function of the entire material. It should be noted that after a section of fabric is cut and edged, all drive components (motor 1, motor 2, motor 393) stop running, and all telescopic components (hydraulic telescopic rod 16, electric telescopic rod 13, electric telescopic rod 2 32, hydraulic telescopic column 36) retract, driving the clamping frame 17, tensioning roller 14, fixed frame 33, and movable frame 37 back to their initial positions, preparing for the next section of fabric processing.
[0043] Furthermore, since the movement of the clamping frame 17 is achieved through the flow of hydraulic oil, the movement distance of the clamping frame 17, i.e., the thickness of the material, can be determined by monitoring the flow of the hydraulic oil. Current is then supplied to the electromagnetic block 3865 based on the material thickness. It should be noted that the magnitude of the current supplied to the electromagnetic block 3865 is directly proportional to the movement distance of the clamping frame 17. When current is supplied to the electromagnetic block 3865, the electromagnetic block 3865 becomes magnetic. The repulsive force between the electromagnetic block 3865 and the permanent magnet block 3866 controls the sliding of the movable cover 3864 along the fixed tube 3862, thus changing the opening and closing size of the adjusting hole 3863. Furthermore, an elastic element is provided between the fixed pipe 3862 and the movable cover 3864. When the power supply to the electromagnetic block 3865 is stopped, the elastic element will cause the movable cover 3864 to reset. The hydraulic oil used to drive the cutting tool 398 will enter the fixed pipe 3862 and the recovery pipe 3867 through the connecting pipe 385 and into the hydraulic telescopic column 36. In other words, the fixed pipe 3862 and the recovery pipe 3867 can be regarded as a sealed pipe, and the hydraulic oil will flow continuously. When cutting thinner materials, the electromagnetic block 3865 will push the permanent magnet block 3866 to move a shorter distance, so that the movable cover 3864 also moves along the fixed pipe 3862. Moving a small distance ensures a small connection area between the adjusting hole 3863 and the sealing tube 3861. At this point, hydraulic oil flows quickly into the hydraulic telescopic column 36. However, when cutting thick materials, the electromagnetic block 3865 pushes the permanent magnet block 3866 a longer distance, causing the movable cover 3864 to move a significant distance along the fixed tube 3862. This increases the connection area between the adjusting hole 3863 and the sealing tube 3861, allowing hydraulic oil to flow more slowly into the hydraulic telescopic column 36. When the cutting tool 398 is cutting, it not only moves at a slower speed but also reduces the amount of hydraulic oil flowing into the hydraulic telescopic column 36. The force applied before cutting ensures a smooth cut surface when cutting thick materials, preventing material from getting tangled on the surface of the cutting blade 398 due to excessive speed. In other words, when cutting thinner materials, the cutting blade 398 will complete the cut at a faster speed, while when cutting thicker materials, the cutting blade 398 will complete the cut more slowly. This not only ensures the cutting efficiency of the device but also guarantees a smooth cut surface. Furthermore, to minimize the force on thick materials, the rotational speed of the motor 393 is inversely proportional to the thickness of the material; the thicker the material, the lower its rotational speed. This balances cutting efficiency, prevents damage to the material, and protects the saw blade.
[0044] The winding device 5 consists of two cylinder-controlled winding rollers. After cutting, the two cylinders drive the winding rollers to move closer to each other. The transport roller 15 is located between the two winding rollers. That is, when the two winding rollers move closer to each other, they clamp and fix the cut fabric. At this time, the two winding rollers rotate simultaneously to wind up the fabric. The wound fabric can be removed manually, which makes it easier to take it to the next step. It is also easier to stack it in a more standardized manner for easy differentiation.
[0045] It should be noted that most devices need to reduce the feed speed and increase the feed force when cutting thick fabrics. However, for thick fabrics with denser or looser fiber structures, such as thick canvas and plush fabrics, the cutting tool 398 will exert prolonged pressure on local fibers under excessive feed force, resulting in uneven fiber breakage and increased burrs at the edges. Furthermore, when cutting multiple layers of stacked thick fabrics in batches, high feed force can easily create lateral thrust between layers, causing fabric shift. Due to the stacking method, even if the clamping frame 17 is used to press down before cutting, shift will still occur under significant force. By appropriately reducing the feed force and using a low feed speed to reduce the feed force, the force on each layer of fabric can be more even, reducing misalignment and shift caused by excessive thrust between layers, ensuring dimensional consistency of multi-layer cutting, and also preventing local indentations or fiber damage to the bottom layer of fabric due to the combined effects of the pressure from the upper layers and high feed force.
