Description

Technical Field

[0001] The present invention relates to the technical field of wire and cable production and processing, and specifically to a precise winding device for wire and cable processing. Background Art

[0002] In the production and processing process of wire and cable, the wire pay-off machine, as the core equipment for achieving precise winding, its performance directly affects the product quality and production efficiency. With the increasing demand for the quality and specifications of wire and cable in various industries, many obvious shortcomings have emerged in the actual application of existing wire pay-off machines.

[0003] There are deep-seated technical bottlenecks in the actual application of existing wire pay-off machines, such as the lack of dynamic tension control and insufficient adaptive adjustment ability. First, in the winding tension control link, existing equipment generally relies on a fixed mechanical structure to apply a guiding force to the cable, lacking a dynamic feedback mechanism for the real-time tension of the cable. When the cable is wound to the later stage, the increase in the diameter of the winding disc causes a non-linear change in the cable tension, and the traditional mechanical structure cannot adjust the guiding pressure synchronously, which is likely to cause the following problems: Tension overload: The cable undergoes tensile deformation due to excessive local stress, damaging the insulation layer structure and even causing a wire breakage accident; Tension insufficiency: The cable is wound loosely, the stability of the winding disc structure is poor, and the cable is prone to slip or collapse during transportation. For example, in the production of high-voltage cables, uneven tension may lead to variations in the insulation layer thickness, directly affecting the voltage withstand level and service life of the cable.

[0004] Secondly, regarding the precise control of the number of winding turns and thickness, although the existing technology can calculate the theoretical thickness through the number of turns of the winding wheel and the cable diameter, it cannot calibrate the actual thickness deviation caused by factors such as cable elastic deformation and equipment vibration in real time. The specific pain points include: Static calculation error: The cable undergoes elastic elongation due to the force during winding, resulting in a systematic deviation between the theoretical calculated thickness and the actual winding thickness; Dynamic adjustment lag: When switching to different specifications of cables, the operator needs to manually adjust the parameters of the wire arranging mechanism, unable to achieve rapid adaptive switching of multi-specification products, resulting in low production efficiency; Lack of warning mechanism: Existing equipment can only judge whether the thickness meets the standard through manual measurement after winding is completed, unable to provide real-time feedback on the progress of the number of turns and early warning during the winding process. Often, the entire coil of cable is scrapped due to over-winding or under-winding, and the traditional manual intervention mode is difficult to meet the precision requirements of mass production.

[0005] Furthermore, in terms of the protection of the cable input end, there is almost no targeted protection structure in the existing wire rewinding machine. The cable is vulnerable to external factors at the input end, such as foreign object jamming and accidental pulling. These situations may cause problems such as cable twisting and knotting at the initial stage of winding. Once such problems occur, with the continuous winding, it is very likely to cause the wire reel to become disordered, not only wasting a lot of time to re-organize the cable, but also possibly rendering the entire reel of cable scrapped, seriously affecting the production progress and the economic benefits of the enterprise.

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

[0007] In view of the deficiencies of the prior art, the present invention provides a precise wire winding device for wire and cable processing to solve the problems raised in the above background technology.

[0008] To achieve the above object, the present invention provides the following technical solution: A precise wire winding device for wire and cable processing, comprising: a rewinding machine, an operating table is arranged on the rewinding machine, a wire arranging frame is arranged on one side of the rewinding machine, a guiding shaft is fixedly connected to the end of the wire arranging frame away from the rewinding machine, the guiding shaft drives a wire arranging wheel to move left and right reciprocally to adjust the winding position of the cable, a wire arranging wheel is slidably connected to the guiding shaft, an adaptive guiding mechanism is arranged on the surface of the rewinding machine where the wire arranging frame is located, a cable is arranged on the adaptive guiding mechanism, and a number-of-turns tension control mechanism is arranged inside the adaptive guiding mechanism;

[0009] The adaptive guiding mechanism is used to precisely guide one end of the cable during wire winding and storage so that it is evenly wound;

[0010] The number-of-turns tension control mechanism is used to feedback whether the number of turns has been wound to the specified thickness during the process of winding and storage for timely replacement and to avoid deflection of the cable due to excessive tension.

[0011] Preferably, the adaptive guiding mechanism includes a positioning shaft fixedly connected to one side of the rewinding machine where the wire arranging frame is provided. One end of the positioning shaft away from the rewinding machine is fixedly connected with a U-shaped frame. A receiving disc is fixedly connected inside the U-shaped frame. The cable is wound around the outer circle of the receiving disc. The input end of the cable is slidably connected to the wire arranging wheel. A guiding body is fixedly connected to the inner surface of the U-shaped frame away from the receiving disc. A T-shaped sliding groove is formed inside the guiding body. A T-shaped sliding block is slidably connected inside the T-shaped sliding groove. A ball screw is arranged inside the guiding body. The guiding body is driven by a built-in motor, and the motor is built with an encoder electrically connected to an external controller. The ball screw and the wire arranging wheel inside the guiding body are both electrically connected and controlled by a unified controller to reciprocate. The middle part of the T-shaped sliding block is fixedly connected to the nut of the ball screw. Symmetrical linear guides are fixedly connected inside the guiding body 25. The ball screw and the linear guide arranged inside the guiding body are both arranged inside the T-shaped sliding groove. The linear guide arranged inside the guiding body is slidably connected to the T-shaped sliding block.

[0012] Preferably, the adaptive guiding mechanism further includes an auxiliary housing fixedly connected to the T-shaped sliding block. A fluid cavity is formed at one end of the auxiliary housing away from the T-shaped sliding block. A return spring is fixedly connected inside the fluid cavity. One end of the return spring away from the fluid cavity is fixedly connected with an auxiliary rod. The auxiliary rod is slidably connected inside the auxiliary housing. One end of the auxiliary rod away from the auxiliary housing is fixedly connected with a U-shaped guiding block. A sponge body is inserted into one side surface of the U-shaped guiding block away from the auxiliary rod.

[0013] Preferably, the number-of-turns tension regulating mechanism includes a functional groove formed on the side surface of one end of the auxiliary rod away from the U-shaped guiding block. A positioning body is fixedly connected to the bottom of the functional groove. One end of the positioning body away from the U-shaped frame is fixedly connected with a contact. A trigger body is fixedly connected to the inner wall of the auxiliary housing. The trigger body is located inside the functional groove and on the side of the contact away from the U-shaped guiding block.

[0014] Preferably, the cable extends from the wire arranging wheel end and is wound around the receiving disc. The receiving disc is controlled to wind by its self-configured motor installed inside the rewinding machine. The T-shaped sliding block is slidably adapted to the T-shaped sliding groove.

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

[0016] Preferably, the positioning body is in an inverted F shape, and the contact and the trigger body are used in cooperation.

[0017] Compared with the prior art, the present invention provides a precise winding device for wire and cable processing, having the following beneficial effects:

[0018] 1. Through the setting of the adaptive guiding mechanism, during the process of winding the cable onto the storage disk, the U-shaped frame is firmly installed on one side of the storage disk. The sponge body is fixed through a specific connection method, and with the cooperation of the T-shaped sliding groove and the T-shaped slider, the flexibility of the auxiliary housing moving left and right is assisted. Moreover, under the elastic support of the auxiliary housing on the auxiliary rod, the auxiliary U-shaped guiding block and the sponge body are kept in contact with the cable. The coordinated work of multiple components assists the winding deviation of the cable, ensuring that the cable can always be evenly wound on the storage disk, effectively avoiding problems such as local over-tightening or over-loosening caused by uneven winding, greatly improving the appearance neatness and internal quality of the cable, and ensuring that the cable has good flexibility and strength during subsequent use.

[0019] 2. Through the setting of the sponge body, during the process of accurately winding the cable from the direction of the wire arranging wheel onto the storage disk to form a coil, the dust, oil stains and other impurities attached to the surface of the cable are removed in a timely manner. This can not only keep the appearance of the cable clean, but also prevent the impurities from affecting the insulation performance, signal transmission performance, etc. of the cable, effectively reducing the obstacles in the signal transmission process, ensuring stable and efficient signal transmission, avoiding the situation that the impurities will damage the insulation layer of the cable, causing safety hazards such as electric leakage and short circuit, and better maintaining the integrity and performance stability of the insulation layer, ensuring the safe and reliable power transmission.

[0020] 3. Through the setting of components such as the auxiliary rod, positioning body and contact point, according to the change of the diameter of the storage disk, when the diameter of the storage disk changes during the cable winding process, the position of the contact point is synchronously pushed to change. When the number of turns reaches the standard, the contact point contacts the trigger body to conduct electricity, forming a thickness compliance verification switch. When the displacement of the auxiliary rod reaches the theoretically calculated value, the electronic counting error is forcibly calibrated through physical contact signals, reducing technical errors, avoiding the "false winding" phenomenon that cannot be sensed due to the change of cable tension when counting through the encoder of the storage disk motor during the cable winding process, thus avoiding product unqualified and raw material waste caused by inaccurate number of turns, such as the situation where there are gaps between cables when the tension is insufficient and the actual thickness is less than the theoretically calculated value, significantly shortening the production cycle and making the production process more efficient and smooth.

[0021] 4. Through the setting of the number-of-turns tension control mechanism, the auxiliary housing is filled with a thickened non-Newtonian fluid, whose dynamic viscosity exhibits an exponential growth characteristic with the shear rate. When the cable generates an instantaneous acceleration breaking force due to tension overload, the auxiliary rod impacts the inner cavity of the fluid, and the non-Newtonian fluid instantaneously hardens into an elastic modulus-like solid structure. Through the dual effects of rigidly locking the displacement of the auxiliary rod and the groove limit of the U-shaped guide block, and in conjunction with the dynamic friction coefficient generated by the grid-like anti-slip pattern on the surface of the sponge body, an axial sliding resistance is formed. At the same time, an interlocking limit effect is generated through the contact friction force between the turns of adjacent cables, reducing the maximum number of sliding turns of the entire coil of cable under the action of the breaking force, significantly superior to the phenomenon of complete disintegration without protection in the prior art. This mechanism can not only quickly suppress the disorderly sliding of the cable, but also trigger the emergency stop program of the motor of the rewinding machine through the fluid hardening signal, achieving triple protection of 'impact perception - rigid locking - power cut-off', fundamentally solving the problem of coil collapse caused by tension out-of-control in traditional equipment.

[0041] For a further embodiment: Please refer to Figures 6 to 8 as shown:

[0042] The number-of-turns tension control mechanism 3 is used to feedback whether the number of turns is wound to a specified thickness during the winding and storage process for timely replacement and to avoid deflection due to overloading of the tension of the cable 24. The number-of-turns tension control mechanism 3 includes a functional groove 31. The functional groove 31 is opened 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 groove 31. The positioning body 32 is an inverted F shape.

The contact 33 is mainly used to fit with the trigger body 34 after the number of turns of the cable 24 gradually increases to trigger a prompt that the winding is in place. 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 groove 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 cooperation.

[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 wire arranging frame 12 to the wire arranging frame 12, wound and conveyed to the storage disc 23 for winding and storing, and the sponge body 213 abuts against the cable 24.

[0045] The following is the working process of the adaptive guiding mechanism 2 for precisely guiding one end of the cable 24 to make it evenly wound when winding and storing the cable 24:

[0046] When in use, when the cable 24 is wound around the storage tray 23 for winding and closing, the U-shaped frame 21 is fixed to one side of the storage tray 23, and the guide body 25 serves as a connection carrier between the U-shaped frame 21 and the subsequent auxiliary structure. The T-shaped slide groove 26 opened inside it and the T-shaped slider 27 sliding inside it cooperate to provide basic conditions for the left and right movement of the auxiliary shell 28. At this time, the reset spring 210 in the auxiliary shell 28 is in a natural state. The auxiliary rod 211, under the action of the reset spring 210 and the sliding insertion in the auxiliary shell 28, stably supports the U-shaped guide block 212, so that the sponge 213 at one end of the U-shaped guide block 212 fits and contacts the cable 24; then as the storage tray 23 starts to rotate, the cable 24 gradually moves. The cable 24 is gradually wound around the outer ring of the storage tray 23. During the winding process, the left and right movement of the cable wheel 14 causes the cable 24 to be gradually wound along the outer surface of the storage tray 23 during the winding process, thereby generating a tendency of deviation in the left and right directions. When the cable 24 deviates to one side, it generates a lateral squeezing force on the sponge 213. At the same time, since the drive of the built-in ball screw of the guide body 25 and the drive of the cable wheel 14 are connected to the same controller for control, when the cable wheel 14 reciprocates left and right, the power supply of the ball screw is synchronously started to cause it to rotate. Under the meshing action of the ball and nut provided on the ball screw, it is converted into a linear motion of the nut. The linear motion of the nut drives the T-shaped slider 27 to reciprocate linearly in the T-shaped slide groove 26. With the assistance of the linear guide rail provided in the guide body 25, the T-shaped slider 27 is further made to smoothly perform linear motion in the T-shaped slide groove 26, and the position signal of the T-shaped slider 27 is fed back through the built-in encoder of the motor of the ball screw. When the T-shaped slider 27 reaches the target position, the controller controls the motor to rotate in the opposite direction to form a reciprocating motion. The above-mentioned coordinated use further ensures the smooth movement of the auxiliary shell 28 through the movement of the T-shaped slider 27 and transmits it to the sponge body 213 to guide the cable 24; due to the movement of the auxiliary shell 28, the sponge body 213 changes synchronously with the winding deflection position of the cable 24, thereby cooperating with the cable wheel 14 to apply the same guiding force to the cable 24, guiding the winding direction of the cable 24 The correctness of the cable 24 is avoided to avoid deviation when the cable 24 is wound on the storage tray 23. When the cable 24 is gradually wound to the outer circle of the storage tray 23, the diameter of the storage tray 23 is continuously expanded. At this time, under the contact effect of the cable 24 and the sponge 213, a contact force is given to the sponge 213 to move into the auxiliary shell 28, prompting the sponge 213 to push the auxiliary rod 211 to shrink and move into the auxiliary shell 28. In this way, when the number of turns of the cable 24 wound on the storage tray 23 changes, the distance between the sponge 213 and the cable 24 is adjusted synchronously. At this time, the reset spring 210 is compressed to help ensure the integrity of the guiding function and avoid the deflection of the cable 24 during the winding process, which leads to uneven storage of the winding disk.

[0047] Further, during the process of winding the cable 24 around the storage reel 23, as the number of winding turns of the cable 24 continuously increases, the overall diameter of the storage reel 23 gradually increases. The cable 24 slides at a constant speed, driving 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 the cable 24 against the sponge body 213 in contact with it to change, thereby pushing the sponge body 213, the U-shaped guide block 212, and the auxiliary rod 211 to move into the auxiliary housing 28 together. During this process, the return spring 210 is continuously compressed, storing elastic potential energy. When the wound cable 24 is removed after the storage reel 23 has completed storage, due to the decrease in diameter, the elastic potential energy stored in the return spring 210 is released, causing the U-shaped guide block 212 and the sponge body 213 to return to their original positions, waiting for the next winding operation. And if, during the winding of the cable 24, due to external interference or equipment failure, etc., the tension of the cable 24 suddenly becomes too large, generating a breaking force that may cause the reel to collapse, such as at the moment of wire breakage: this breaking force will instantaneously act on the auxiliary rod 211, increasing its axial speed and causing the auxiliary rod 211 to quickly contract and move into the auxiliary housing 28. Since the auxiliary housing 28 is filled with non-Newtonian fluid, when the auxiliary rod 211 impacts the non-Newtonian fluid at high speed and the cable 24 instantaneously accelerates and slides, the friction between the fluid molecules surges, and the equivalent damping coefficient suddenly increases from its normal state and quickly hardens into a solid state within milliseconds, forming a rigid support structure that locks the displacement of the auxiliary rod 211, showing a hardening characteristic. Due to the hardening of the non-Newtonian fluid, the auxiliary rod 211 cannot continue to extend and move into the auxiliary housing 28. At this time, the auxiliary rod 211 remains relatively fixed, and thus the positions of the U-shaped guide block 212 and the sponge body 213 connected to it are fixed. The friction coefficient of the sponge body 213 is relatively high, and the contact surface with the cable 24 is a micro-arc surface (curvature radius R = diameter of the cable 24 × 1.2), when the non-Newtonian fluid hardens, the maximum friction force of the sponge body 213 and the structural limit form a composite resistance to offset the axial sliding trend of the cable 24 (friction force calculation formula: Ff = μ × Fn, where Fn is the supporting force after the non-Newtonian fluid hardens), so as to offset the cable reel bursting force. At the same time, although a single U-shaped guiding block 212 only acts on a local cable 24, during the winding process, multiple turns of the cable 24 form a chain constraint through friction: when a certain turn of the cable 24 slides due to the bursting force, it exerts a pulling effect on the adjacent turn of the cable 24; after the non-Newtonian fluid hardens, the U-shaped guiding block 212 locks this turn of the cable 24, and transfers the binding force to the entire reel of cable 24 through the friction between turns to inhibit overall sliding. Furthermore, the pressure sensor in the auxiliary housing 28 is used to monitor the fluid pressure in real time. When the pressure exceeds the threshold value, the power supply of the motor is cut off at the fastest speed and the electromagnetic brake is activated to stop the storage reel 23 from rotating, further eliminating the subsequent risk of cable 24 slipping. The multiple parties cooperate effectively to prevent the cable 24 from sliding disorderly due to excessive tension, prevent the cable 24 wound on the storage reel 23 from getting chaotic, protect the winding result, and avoid production interruption and material waste.

[0048] Through the setting of the adaptive guiding mechanism 2, during the process of winding the cable 24 onto the storage reel 23, the U-shaped frame 21 is firmly installed on one side of the storage reel 23. The sponge body 213 is fixed through a specific connection method, and with the cooperation of the T-shaped chute 26 and the T-shaped slider 27, it helps to improve the flexibility of the left and right movement of the auxiliary housing 28. And under the elastic support of the auxiliary housing 28 on the auxiliary rod 211, it helps the U-shaped guiding block 212 and the sponge body 213 to keep in contact with the cable 24. The coordinated work of multiple components helps the winding deviation of the cable 24, ensuring that the cable 24 can always be evenly wound on the storage reel 23, effectively avoiding problems such as local over-tightening or over-loosening caused by uneven winding, greatly improving the appearance neatness and internal quality of the cable 24, and ensuring that the cable 24 has good flexibility and strength during subsequent use.

[0049] Furthermore, through the setting of components such as the auxiliary rod 211, the positioning body 32, and the contact 33, when the diameter of the storage reel 23 changes during the winding process of the cable 24, the position of the contact 33 is synchronously pushed to change. When the number of turns reaches the standard, the contact 33 contacts the trigger body 34 to conduct electricity, forming a thickness compliance verification switch. When the displacement of the auxiliary rod 211 reaches the theoretically calculated value, the electronic counting error is forcibly calibrated through the physical contact signal, reducing technical errors, and avoiding the "false winding" phenomenon where the cable 24 cannot be sensed due to tension changes when counting through the motor encoder of the storage reel 23, thus avoiding product unqualified and raw material waste caused by inaccurate number of turns, such as the situation where there are gaps between the cables 24 when the tension is insufficient and the actual thickness is less than the theoretically calculated value, significantly shortening the production cycle and making the production process more efficient and smooth.

[0050] Through the arrangement of the spongy body 213, during the process of accurately winding the cable 24 from the direction of the wire arranging wheel 14 onto the storage disc 23, dust, oil stains and other impurities attached to the surface of the cable 24 can be removed in time, which can not only keep the appearance of the cable 24 clean, but also prevent the impurities from affecting the insulation performance, signal transmission performance, etc. of the cable 24, effectively reducing the obstacles in the signal transmission process, ensuring the stable and efficient transmission of signals, avoiding the impurities from damaging the insulation layer of the cable and causing safety hazards such as electric leakage and short circuit, better maintaining the integrity and performance stability of the insulation layer, and ensuring the safe and reliable power transmission.

[0051] Please refer to the above working process Figures 1 to 5 。

[0052] The following is the working process of the number-of-turns tension control mechanism 3 for feeding back whether the number of turns is wound to the specified thickness during the winding and storage process to facilitate timely replacement and avoid deflection due to overloading of the tension of the cable 24:

[0053] During use, as the cable 24 wound on the storage disc 23 gradually increases, causing the diameter of the storage disc 23 to increase, the auxiliary rod 211 slides into the auxiliary housing 28, the return spring 210 is continuously compressed, and the function groove 31 opened on the auxiliary rod 211 moves synchronously towards the auxiliary housing 28, driving the positioning body 32 and the contact 33 fixedly connected to the function groove 31 to gradually approach the trigger body 34 fixedly connected to the auxiliary housing 28. When the auxiliary rod 211 moves towards the auxiliary housing 28, the contact 33 moves synchronously. As the number of turns of the cable 24 wound continuously approaches the preset standard, the auxiliary rod 211 continues to move, and the contact 33 precisely fits with the trigger body 34, triggering the pre-connected circuit system. Then, under the position feedback of the built-in encoder of the ball screw motor, the ball screw continuously rotates to drive the T-shaped slider 27 to displace to the other end, completing a full turn of winding operation, making a prompt to the operator, informing that the number of turns of the cable 24 wound has met the requirements, and the storage disc 23 can be replaced in time to start the next round of winding operation.

[0054] Through the setting of the number-of-turns 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 generates an instantaneous acceleration breaking force due to tension overload, the auxiliary rod 211 impacts the inner cavity 29 of the fluid, and the non-Newtonian fluid instantly hardens into an elastic modulus-like solid structure. Through the dual actions of rigidly locking the displacement of the auxiliary rod 211 and the groove limit of the U-shaped guide block 212, and in conjunction with the dynamic friction coefficient generated by the grid-like anti-slip pattern on the surface of the sponge body 213, an axial sliding resistance is formed. At the same time, an interlocking limit effect is generated by the contact friction force between the turns of the adjacent cables 24, reducing the maximum number of sliding turns of the entire coil of cable 24 under the action of the breaking force, significantly superior to the phenomenon of the entire coil disintegrating without protection in the prior art. This mechanism can not only quickly suppress the disorderly sliding of the cable 24, but also trigger the emergency stop program of the motor of the rewinder 1 through the fluid hardening signal, realizing triple protection of 'impact perception - rigid locking - power cut-off', fundamentally solving the problem of coil collapse caused by tension out-of-control in traditional equipment.
