Description

Technical Field

[0001] This invention relates to the field of wire and cable production and processing technology, specifically to a precision winding device for wire and cable processing. Background Technology

[0002] In the production and processing of wires and cables, the wire rewinding machine is a core piece of equipment for achieving precise winding, and its performance directly affects product quality and production efficiency. With the increasing demands from various industries for the quality and diverse specifications of wires and cables, existing wire rewinding machines have revealed many significant shortcomings in practical applications.

[0003] Existing wire rewinding machines suffer from deep-seated technical bottlenecks in practical applications, including a lack of dynamic tension control and insufficient adaptive adjustment capabilities. Firstly, in the winding tension control stage, existing equipment generally relies on fixed mechanical structures to apply guiding force to the cable, lacking a dynamic feedback mechanism for real-time cable tension. When the cable is wound to the later stages, the increased diameter of the winding reel causes non-linear changes in cable tension. Traditional mechanical structures cannot synchronously adjust the guiding pressure, easily leading to the following problems: Tension overload: The cable undergoes tensile deformation due to excessive localized stress, damaging the insulation structure and even causing wire breakage; Insufficient tension: The cable is loosely wound, the winding reel structure has poor stability, and the cable is prone to slippage or collapse during transportation. For example, in high-voltage cable production, uneven tension can lead to variations in insulation thickness, directly affecting the cable's withstand voltage rating and service life.

[0004] Secondly, regarding the precise control of the number of coils and thickness, while existing technologies can calculate the theoretical thickness using the number of turns on the winding wheel and the cable diameter, they cannot calibrate in real time the actual thickness deviation caused by factors such as cable elastic deformation and equipment vibration. Specific pain points include: static calculation error: the cable elongates elastically due to stress during winding, leading to a systematic deviation between the theoretically calculated thickness and the actual winding thickness; dynamic adjustment lag: when switching between different cable specifications, operators need to manually adjust the parameters of the cable laying mechanism, making it impossible to achieve rapid adaptive switching between multiple specifications, resulting in low production efficiency; lack of early warning mechanism: existing equipment can only judge whether the thickness meets the standard by manual measurement after winding, and cannot provide real-time feedback on the number of turns and early warning during winding. Over-winding or under-winding often leads to the scrapping of the entire spool of cable, and the traditional manual intervention mode cannot meet the precision requirements of mass production.

[0005] Furthermore, existing cable reeling machines lack specific protective structures at the cable input end. Cables are susceptible to external interference at the input end, such as obstruction by foreign objects or accidental pulling. These factors can cause twisting and knotting in the initial winding stage. Once such problems occur, as winding continues, the reel is highly likely to break apart, requiring significant time to reorganize the cable and potentially rendering the entire reel unusable, severely impacting production progress and the company's economic benefits.

[0006] Therefore, a precision winding device for wire and cable processing was proposed to solve the above problems. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a precision winding device for wire and cable processing, thereby solving the problems mentioned in the background section.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a precision winding device for wire and cable processing, comprising: a rewinding machine, an operating table on the rewinding machine, a wire guide frame on one side of the rewinding machine, a guide shaft fixedly connected to the end of the wire guide frame away from the rewinding machine, the guide shaft driving the wire guide wheel to move left and right back and forth to adjust the winding position of the cable, the wire guide wheel being slidably connected to the guide shaft, an adaptive guiding mechanism on the side of the rewinding machine where the wire guide frame is located, a cable being mounted on the adaptive guiding mechanism, and a turn tension adjustment mechanism being located inside the adaptive guiding mechanism;

[0009] The adaptive guiding mechanism is used to precisely guide one end of the cable to ensure even winding when the cable is being wound and stored.

[0010] The coil tension control mechanism is used to provide feedback on whether the number of coils has been wound to the specified thickness during the winding and storage process, so as to facilitate timely replacement and avoid cable tension overload and deflection.

[0011] Preferably, the adaptive guiding mechanism includes a positioning shaft, which is fixedly connected to one side of the rewinding machine where a cable tray is provided. A U-shaped frame is fixedly connected to the end of the positioning shaft away from the rewinding machine. A storage tray is fixedly connected inside the U-shaped frame. The cable is wound around the outer ring of the storage tray. The input end of the cable is slidably connected to the cable tray. A guide body is fixedly connected to the inner surface of the U-shaped frame away from the storage tray. A T-shaped groove is formed inside the guide body. A T-shaped slider is slidably connected inside the T-shaped groove. A ball screw is built into the guide body. The guide body is driven by a built-in motor, and the motor has a built-in encoder that is electrically connected to an external controller. The ball screw and the cable tray inside the guide body are both electrically connected and controlled by a unified controller for reciprocating motion. The middle part of the T-shaped slider is fixedly connected to the nut of the ball screw. A symmetrical linear guide rail is fixedly connected inside the guide body 25. The ball screw and the linear guide rail inside the guide body are both set in the T-shaped groove. The linear guide rail inside the guide body is slidably connected to the T-shaped slider.

[0012] Preferably, the adaptive guiding mechanism further includes an auxiliary housing, which is fixedly connected to a T-shaped slider. The auxiliary housing has a fluid cavity at the end away from the T-shaped slider, and a return spring is fixedly connected inside the fluid cavity. An auxiliary rod is fixedly connected at the end of the return spring away from the fluid cavity. The auxiliary rod is slidably connected inside the auxiliary housing, and a U-shaped guide block is fixedly connected at the end of the auxiliary rod away from the auxiliary housing. A sponge is inserted into the side of the U-shaped guide block away from the auxiliary rod.

[0013] Preferably, the tension control mechanism includes a functional slot, which is located on the side of the auxiliary rod away from the U-shaped guide block. A positioning body is fixedly connected to the bottom of the functional slot, and a contact is fixedly connected to the end of the positioning body away from the U-shaped frame. A trigger body is fixedly connected to the inner wall of the auxiliary housing, and the trigger body is located inside the functional slot and on the side of the contact away from the U-shaped guide block.

[0014] Preferably, the cable extends from the end of the cable tray and winds onto the receiving tray, which is controlled by a motor installed in the rewinding machine, and the T-shaped slider slides and is adapted to slide onto the T-shaped groove.

[0015] Preferably, the fluid cavity contains a non-Newtonian fluid, the auxiliary rod is slidably adapted to the auxiliary housing, and the sponge can be disassembled and replaced with the U-shaped guide block.

[0016] Preferably, the positioning body is inverted F-shaped, and the contact point is used in conjunction with the trigger body.

[0017] Compared with the prior art, the present invention provides a precision winding device for wire and cable processing, which has the following advantages:

[0018] 1. Through the adaptive guide mechanism, the U-shaped frame is securely installed on one side of the storage tray during the cable winding process. The sponge is fixed by a specific connection method, and with the cooperation of the T-shaped groove and T-shaped slider, the auxiliary housing moves flexibly left and right. Under the elastic support of the auxiliary housing on the auxiliary rod, the auxiliary U-shaped guide block and the sponge keep in contact with the cable. The coordinated work of multiple components and the auxiliary cable winding offset ensure that the cable can always be evenly wound on the storage tray, effectively avoiding the problem of local over-tightness or over-looseness caused by uneven winding. This greatly improves the appearance neatness and internal quality of the cable, ensuring that the cable has good flexibility and strength in subsequent use.

[0019] 2. By incorporating a sponge, dust, oil, and other impurities adhering to the cable surface are promptly removed during the precise winding process from the cable guide wheel onto the receiving reel. This not only maintains the cable's clean appearance but also prevents impurities from affecting its insulation and signal transmission performance. It effectively reduces obstacles during signal transmission, ensuring stable and efficient signal transmission. This also prevents impurities from damaging the cable's insulation layer, which could lead to safety hazards such as leakage and short circuits. Furthermore, it better maintains the integrity and performance stability of the insulation layer, ensuring safe and reliable power transmission.

[0020] 3. By setting up components such as auxiliary rods, positioning bodies, and contacts, the position of the contacts is synchronously changed as the diameter of the receiving reel changes during the cable winding process. When the number of turns reaches the standard, the contacts contact the trigger body to energize, forming a thickness verification switch. When the displacement of the auxiliary rod reaches the theoretical calculation value, the electronic counting error is forcibly calibrated through physical contact signal, reducing technical errors and avoiding the inability to detect the "virtual winding" phenomenon caused by cable tension changes when counting through the receiving reel motor encoder. This prevents inaccurate turn counts, resulting in product defects and material waste. It also addresses situations where there are gaps between cables due to insufficient tension, and the actual thickness is less than the theoretical calculation value. This significantly shortens the production cycle and makes the production process more efficient and smooth.

[0021] 4. Through the setting of the coil tension control mechanism, the auxiliary shell is filled with a thickened non-Newtonian fluid, whose dynamic viscosity increases exponentially with the shear rate. When the cable experiences a sudden acceleration due to tension overload, the auxiliary rod impacts the fluid cavity, and the non-Newtonian fluid instantly hardens into a solid structure with an elastic modulus. Through the dual action of rigidly locking the displacement of the auxiliary rod and limiting the groove of the U-shaped guide block, combined with the dynamic friction coefficient generated by the grid-like anti-slip texture on the surface of the sponge, axial sliding resistance is formed. At the same time, the contact friction between the coils of adjacent cables generates a chain limiting effect, reducing the maximum number of coils of slippage of the entire cable under the action of the collapse force. This is significantly better than the phenomenon of complete collapse of the entire cable without protection in the existing technology. This mechanism can not only quickly suppress the disorderly slippage of the cable, but also trigger the motor emergency stop program of the rewinding machine through the fluid hardening signal, realizing triple protection of 'impact sensing-rigid locking-power cutting off', fundamentally solving the problem of collapse caused by tension loss in traditional equipment.

[0039] The adaptive guiding mechanism 2 is used to precisely guide one end of the cable 24 during winding and storage, ensuring even winding. The adaptive guiding mechanism 2 includes a positioning shaft 22, which is fixedly connected to one side of the rewinding machine 1 where the cable tray 12 is located. A U-shaped frame 21 is fixedly connected to the end of the positioning shaft 22 away from the rewinding machine 1. A storage tray 23 is fixedly connected inside the U-shaped frame 21. The storage tray 23 is wound by a motor installed within the rewinding machine 1. The cable 24 is wound around the outer ring of the storage tray 23, extending from the end of the cable tray 14 and winding onto the storage tray 23. The input end of the cable 24 is slidably connected to the cable tray 14. A guide body 25 is fixedly connected to the inner surface of the U-shaped frame 21 away from the storage tray 23. A T-shaped groove 26 is formed inside the guide body 25. 6 is mainly used to assist the straight sliding of the T-shaped slider 27. The T-shaped slider 27 is slidably connected in the T-shaped groove 26. The T-shaped slider 27 is mainly used to cooperate with the cable guide wheel 14 to accurately control the winding of the cable 24. The T-shaped slider 27 and the T-shaped groove 26 are slidably adapted to each other. The guide body 25 has a built-in ball screw. The guide body 25 is driven by a built-in motor and the motor has a built-in encoder that is electrically connected to an external controller. The ball screw in the guide body 25 and the cable guide wheel 14 are electrically connected and controlled by a unified controller to reciprocate. The middle part of the T-shaped slider 27 is fixedly connected to the nut of the ball screw. The guide body 25 is fixedly connected to a symmetrical linear guide. The ball screw and the linear guide in the guide body 25 are both set in the T-shaped groove 26. The linear guide in the guide body 25 is slidably connected to the T-shaped slider 27.

[0040] The adaptive guiding mechanism 2 also includes an auxiliary housing 28, which houses a pressure sensor electrically connected to the main controller. The auxiliary housing 28 is fixedly connected to a T-shaped slider 27. A fluid cavity 29 is formed at the end of the auxiliary housing 28 furthest from the T-shaped slider 27. A return spring 210 is fixedly connected within the fluid cavity 29. The return spring 210 mainly assists in the movement and reset of the auxiliary rod 211. An auxiliary rod 211 is fixedly connected at the end of the return spring 210 furthest from the fluid cavity 29. The auxiliary rod 211 is slidably connected within the auxiliary housing 28. The internal device contains a non-Newtonian fluid. The non-Newtonian fluid in the fluid cavity 29 is mainly to prevent the cable 24 from tangling and deflecting due to excessive tension. The auxiliary rod 211 is slidably adapted to the auxiliary housing 28. A U-shaped guide block 212 is fixedly connected to the end of the auxiliary rod 211 away from the auxiliary housing 28. A sponge 213 is inserted into the side of the U-shaped guide block 212 away from the auxiliary rod 211. The surface of the sponge 213 is provided with a grid-like anti-slip texture. The sponge 213 is mainly used to adhere to the cable 24 and wipe it clean. The sponge 213 can be disassembled and replaced with the U-shaped guide block 212.

[0041] A further embodiment: Please refer to Figures 6 to 8 As shown:

[0042] The coil tension control mechanism 3 is used to provide feedback on whether the number of coils has been wound to the specified thickness during the winding process, so as to facilitate timely replacement and prevent the cable 24 from deflecting due to overload. The coil tension control mechanism 3 includes a functional slot 31, which is located on the side of the auxiliary rod 211 away from the U-shaped guide block 212. A positioning body 32 is fixedly connected to the bottom of the functional slot 31. The positioning body 32 is inverted F-shaped. A contact 33 is fixedly connected to the end of the positioning body 32 away from the U-shaped frame 21. The contact 33 is mainly used to trigger the winding to complete when it comes into contact with the trigger body 34 as the number of coils of the cable 24 gradually increases. The trigger body 34 is fixedly connected to the inner wall of the auxiliary housing 28. The trigger body 34 is located inside the functional slot 31 and on the side of the contact 33 away from the U-shaped guide block 212. The contact 33 and the trigger body 34 are used in conjunction.

[0043] The working principle of all the content in the above embodiments is as follows:

[0044] In the initial state: the cable 24 is transmitted from the side away from the cable tray 12 to the cable tray 12 and wound and transported to the storage tray 23 for winding and coiling, and the sponge 213 is in contact with the cable 24.

[0045] The following describes the working process of the adaptive guide mechanism 2, which precisely guides one end of cable 24 to ensure even winding during cable winding and storage:

[0046] In use, when the cable 24 is wound onto the storage tray 23 for winding and coiling, the U-shaped frame 21 is fixed to one side of the storage tray 23. The guide body 25 serves as the connecting carrier between the U-shaped frame 21 and the subsequent auxiliary structure. The T-shaped groove 26 inside the guide body 25, along with the T-shaped slider 27 sliding inside, provides the basic conditions for the left and right movement of the auxiliary housing 28. At this time, the return spring 210 inside the auxiliary housing 28 is in its natural state. Under the action of the return spring 210 and the sliding insertion within the auxiliary housing 28, the auxiliary rod 211 stably supports the U-shaped guide block 212, causing the sponge 213 at one end of the U-shaped guide block 212 to contact the cable 24. Then, as the storage tray 23 begins to rotate, the cable 24 gradually... The cable 24 is wound around the outer ring of the storage tray 23. During the winding process, the left and right movement of the cable guide wheel 14 causes the cable 24 to gradually wind along the outer surface of the storage tray 23, resulting in a left-right offset tendency. When the cable 24 offsets to one side, it exerts a lateral squeezing force on the sponge 213. At the same time, since the drive of the ball screw built into the guide body 25 is connected to the drive of the cable guide wheel 14 and controlled by the same controller, when the cable guide wheel 14 moves left and right, the power supply of the ball screw is started synchronously, causing it to rotate. Under the meshing action of the balls set on the ball screw and the nut, it is converted into the linear motion of the nut. The linear motion of the nut drives the T-shaped slider 27 to reciprocate linearly within the T-shaped groove 26. With the assistance of the linear guide rail installed inside the guide body 25, the T-shaped slider 27 moves smoothly in a linear motion within the T-shaped groove 26. The position signal of the T-shaped slider 27 is fed back through the encoder built into the ball screw motor. When the T-shaped slider 27 reaches the target position, the controller controls the motor to rotate in the opposite direction, thus forming a reciprocating motion. The above-mentioned combination further ensures the smooth movement of the auxiliary housing 28 through the movement of the T-shaped slider 27 and transmits the control of the sponge body 213 to guide the cable 24. Due to the movement of the auxiliary housing 28, the sponge body 213 changes synchronously with the winding deflection position of the cable 24, thereby cooperating with the cable guide wheel 14 to apply the same guiding force to the cable 24 and guide the winding direction of the cable 24. To ensure the correctness of the winding and prevent the cable 24 from deviating when it is wound on the storage reel 23, as the cable 24 gradually winds to the outer ring of the storage reel 23, the diameter of the storage reel 23 continuously expands. At this time, under the contact and resistance between the cable 24 and the sponge 213, the sponge 213 is given a resistance force to move into the auxiliary housing 28, causing the sponge 213 to push the auxiliary rod 211 to retract into the auxiliary housing 28. In this way, when the number of turns of the cable 24 wound on the storage reel 23 changes, the contact distance between the sponge 213 and the cable 24 is adjusted synchronously. At this time, the return spring 210 is compressed to help ensure the integrity of the guiding function and prevent the cable 24 from deflecting during the winding process, which would cause uneven winding of the reel.

[0047] Furthermore, during the winding process of cable 24 on the receiving reel 23, as the number of turns of cable 24 increases, the overall diameter of the receiving reel 23 gradually increases. Cable 24 slides at a constant speed, causing the auxiliary rod 211 to move slowly. The non-Newtonian fluid is in a liquid state, allowing the auxiliary rod 211 to smoothly adjust its position through fluid damping. The increased diameter causes the pressure direction of cable 24 on the sponge 213 that it is in contact with to change, thereby pushing the sponge 213, U-shaped guide block 212, and auxiliary rod 211 together to move into the auxiliary housing 28. During this process, the return spring 210 is continuously compressed, storing elastic potential energy. When the receiving reel 23 finishes storing the cable 24 and removes it, the reduced diameter causes the elastic potential energy stored in the return spring 210 to be released, causing the U-shaped guide block 212 and sponge 213 to reset, waiting for the next winding operation. Moreover, if during the winding process of cable 24, external factors or equipment failure cause the cable to be damaged, the cable 24 may be damaged. When the tension of cable 24 suddenly becomes too high, generating a collapse force that triggers a break, such as at the moment of wire breakage: this collapse force will instantly act on the auxiliary rod 211, increasing its axial velocity and causing the auxiliary rod 211 to rapidly contract and move into the auxiliary housing 28. Since the auxiliary housing 28 is filled with a non-Newtonian fluid, when the cable 24 is subjected to the high-speed impact of the auxiliary rod 211, the auxiliary rod 211 impacts the non-Newtonian fluid, and the friction between fluid molecules surges, causing the equivalent damping coefficient to increase sharply from the normal state. Within milliseconds, it rapidly hardens into a solid state, forming a rigid support structure that locks the displacement of the auxiliary rod 211, exhibiting hardening characteristics. Due to the hardening of the non-Newtonian fluid, the auxiliary rod 211 can no longer extend into the auxiliary housing 28. At this time, the auxiliary rod 211 remains in a relatively fixed state, thereby fixing the positions of the U-shaped guide block 212 and the sponge 213 connected to it. The sponge 213 has a high coefficient of friction and its contact surface with the cable 24 is a micro-arc surface (radius of curvature R = diameter of cable 24 × 1).2) During the hardening of the non-Newtonian fluid, the maximum friction of the sponge 213 and the structural constraint form a combined resistance, which counteracts the axial sliding tendency of the cable 24 (friction calculation formula: Ff=μ×Fn, where Fn is the supporting force after the non-Newtonian fluid hardens), thus counteracting the coil breakage force. Simultaneously, although a single U-shaped guide block 212 only acts on a local portion of the cable 24, multiple turns of cable 24 form a chain constraint through friction during the winding process: when a turn of cable 24 slides due to breakage force, it exerts a pulling effect on adjacent turns of cable 24; after the non-Newtonian fluid hardens, the U-shaped guide... Block 212 locks the coiled cable 24, transmitting constraint force to the entire coil of cable 24 through inter-coil friction, thus suppressing overall slippage. Furthermore, a pressure sensor within the auxiliary housing 28 monitors fluid pressure in real time. When the pressure exceeds a threshold, the motor power is quickly cut off and the electromagnetic brake is activated, stopping the rotation of the receiving tray 23. This further eliminates the risk of subsequent cable 24 slippage. This multi-pronged approach effectively prevents disorderly slippage of the cable 24 due to excessive tension, preventing the cable 24 already wound on the receiving tray 23 from becoming tangled, protecting the winding results, and avoiding production interruptions and material waste.

[0048] With the adaptive guide mechanism 2 in place, as the cable 24 is wound onto the storage tray 23, the U-shaped frame 21 is securely installed on one side of the storage tray 23, and the sponge 213 is fixed by a specific connection method. With the cooperation of the T-shaped slide 26 and the T-shaped slider 27, the auxiliary housing 28 is assisted in moving flexibly left and right. Under the elastic support of the auxiliary rod 211 by the auxiliary housing 28, the auxiliary U-shaped guide block 212 and the sponge 213 are kept in contact with the cable 24. The coordinated work of multiple components and the winding offset of the auxiliary cable 24 ensure that the cable 24 can always be wound evenly on the storage tray 23, effectively avoiding the problem of local over-tightness or over-looseness caused by uneven winding. This greatly improves the appearance neatness and internal quality of the cable 24, ensuring that the cable 24 has good flexibility and strength in subsequent use.

[0049] Furthermore, through the setting of components such as auxiliary rod 211, positioning body 32, and contact 33, according to the change in the diameter of the storage tray 23, when the diameter of the storage tray 23 changes during the winding of the cable 24, the position of the contact 33 is pushed to change synchronously. When the number of turns reaches the standard, the contact 33 contacts the trigger body 34 to conduct electricity, forming a thickness standard verification switch. When the displacement of the auxiliary rod 211 reaches the theoretical calculation value, the electronic counting error is forcibly calibrated through physical contact signal, reducing technical errors and avoiding the inability to detect the "virtual winding" phenomenon caused by the tension change of the cable 24 when counting through the motor encoder of the storage tray 23, thus preventing product defects and material waste due to inaccurate number of turns. For example, when the tension is insufficient, there are gaps between the cables 24, and the actual thickness is less than the theoretical calculation value. This significantly shortens the production cycle and makes the production process more efficient and smooth.

[0050] By incorporating the sponge 213, during the precise winding process of the cable 24 from the cable guide wheel 14 onto the receiving tray 23, dust, oil, and other impurities adhering to the surface of the cable 24 are promptly removed. This not only keeps the cable 24 clean but also prevents impurities from affecting its insulation performance and signal transmission performance. It effectively reduces obstacles during signal transmission, ensuring stable and efficient signal transmission. It also prevents impurities from damaging the cable's insulation layer, which could lead to safety hazards such as leakage and short circuits. This better maintains the integrity and performance stability of the insulation layer, ensuring safe and reliable power transmission.

[0051] Please refer to the above work process. Figures 1 to 5 .

[0052] The following describes the working process of the coil tension control mechanism 3, which is used to provide feedback on whether the number of coils has been wound to the specified thickness during the winding and storage process, so as to facilitate timely replacement and prevent cable 24 from deflecting due to tension overload:

[0053] During use, as the number of cables 24 wound on the storage tray 23 gradually increases, the diameter of the storage tray 23 increases. As this process occurs, the auxiliary rod 211 slides into the auxiliary housing 28, the return spring 210 is continuously compressed, and the functional slot 31 on the auxiliary rod 211 moves synchronously towards the auxiliary housing 28. This causes the positioning body 32 and contact 33 fixedly connected to the functional slot 31 to gradually move towards the trigger body 34 fixedly connected inside the auxiliary housing 28. As the auxiliary rod 211 moves towards the auxiliary housing 28, the contact 33 moves synchronously. As the number of turns of the cable 24 approaches the preset standard, the auxiliary rod 211 continues to move, and the contact 33 and trigger body 34 precisely engage, triggering the pre-connected circuit system. Then, under the position feedback of the built-in encoder of the ball screw motor, the ball screw continues to rotate, causing the T-shaped slider 27 to move to the other end, completing the full turn of winding. This alerts the operator that the number of turns of the cable 24 has met the requirements, and the storage tray 23 can be replaced in time to start the next round of winding.

[0054] Through the setting of the coil tension control mechanism 3, the auxiliary housing 28 is filled with a thickened non-Newtonian fluid, whose dynamic viscosity increases exponentially with the shear rate. When the cable 24 experiences a sudden acceleration due to tension overload, the auxiliary rod 211 impacts the fluid cavity 29, and the non-Newtonian fluid instantly hardens into a solid structure with elastic modulus. Through the dual action of rigidly locking the displacement of the auxiliary rod 211 and limiting the groove of the U-shaped guide block 212, combined with the dynamic friction coefficient generated by the grid-like anti-slip texture on the surface of the sponge 213, axial sliding resistance is formed. At the same time, the contact friction between the coils of adjacent cables 24 generates a chain limiting effect, which reduces the maximum number of coils of slippage of the entire cable 24 under the action of the collapse force. This is significantly better than the phenomenon of complete collapse of the entire cable without protection in the prior art. This mechanism can not only quickly suppress the disorderly sliding of the cable 24, but also trigger the motor emergency stop program of the rewinding machine 1 through the fluid hardening signal, realizing triple protection of 'impact sensing-rigid locking-power cutting off', fundamentally solving the problem of collapse caused by tension loss of traditional equipment.
