Description

Technical Field

[0001] This invention relates to the field of double twisting machine equipment technology, and more specifically, to a coaxial double-wheel differential speed wire feeding device. Background Technology

[0002] In industrial fields such as multi-strand wire processing, textiles, cable manufacturing, and composite material molding, the wire feeding device is a key basic equipment. Its stability, synchronization, and controllability directly affect the processing quality and production efficiency of subsequent processes. Existing wire feeding devices mostly adopt a single-axis or single-drive structure, that is, multiple feed rollers are driven synchronously by a single power source to achieve simultaneous supply of multiple wires. However, in actual operation, due to differences in material, diameter, winding tightness, and stress state among different wires, inconsistent loads on the feed rollers can easily occur, leading to problems such as wire feeding speed deviations, tension fluctuations, and even wire breakage, making it difficult to meet the application requirements of high-precision, multi-wire parallel feeding.

[0003] To address these issues, some existing technologies have introduced multi-motor independent drive or differential control schemes. However, these schemes are often complex, with dispersed drive shafts, large overall equipment size, and high installation and maintenance costs. Furthermore, in the case of asymmetrical arrangement of multiple drive units, vibration and off-center loading are prone to occur during operation, affecting long-term operational stability. In addition, in scenarios involving parallel cable laying of multiple lines, existing devices have limited ability to constrain the cable exit direction and path, leading to easy crossing, entanglement, or interference between cables. This not only increases the risk of failure but also limits the cable supply speed and system reliability.

[0004] Therefore, it is necessary to provide a coaxial dual-wheel differential speed wire feeding device to solve the problems of existing technologies, such as complex structure, large size, high cost, easy vibration and off-center load affecting stability, limited wire constraint capacity when multiple lines are laid in parallel, easy cross-entanglement and interference increasing the risk of failure, and restricting wire feeding speed and system reliability. Summary of the Invention

[0005] In view of this, the present invention proposes a coaxial dual-wheel differential speed wire feeding device, which aims to solve the problems of existing technologies such as complex structure, large size, high cost, easy vibration and uneven load affecting stability, limited wire constraint ability when multiple lines are laid in parallel, easy cross-entanglement and interference increasing the risk of failure, and restricting wire feeding speed and system reliability.

[0006] This invention proposes a coaxial dual-wheel differential cable supply device, comprising: Power unit base; A left-side frame and a right-side frame are respectively disposed on both sides of the upper part of the power unit base, and the left-side frame and the right-side frame are coaxially arranged; wherein, a plurality of left-side cable reels are disposed on the left-side frame; A plurality of wire feeding devices are provided, and all of the wire feeding devices are arranged between the left side frame and the right side frame; wherein, the number of left threading tubes is the same as the number of wire feeding devices. The cable guide cylinder and cable guide rollers are provided. The cable guide cylinder is located on the left side of the left frame away from the right side frame. Several cable guide rollers are provided and are located on the side wall of the cable guide rollers away from the right side frame. The number of cable guide rollers is the same as that of the cable feeding device. There are several drive motors, and each drive motor is connected to a left threading drum.

[0007] Furthermore, the coaxial dual-wheel differential wire feeding device also includes a control module, which is connected to the drive motors respectively. The control module is mounted on the power base and is used to receive external control signals and independently adjust the output speed of each drive motor to achieve a wire feeding speed difference between different wire feeding devices.

[0008] Furthermore, the control module includes: Microprocessor unit, speed sensor group and drive circuit unit; The speed sensor group is connected to each drive motor in a one-to-one correspondence. The speed sensor group is used to collect the actual speed of the drive motor in real time and feed it back to the microprocessor unit. The drive circuit unit is electrically connected to the microprocessor unit and each drive motor respectively. The drive circuit unit is used to adjust the working current of the drive motor according to the control command output by the microprocessor unit. The microprocessor unit compares and analyzes the target speed set by the external control signal with the actual speed fed back by the speed sensor group, and dynamically adjusts the output speed of each drive motor through the drive circuit unit.

[0009] Furthermore, the coaxial dual-wheel differential cable supply device also includes a monitoring module, which is installed on the cable supply device; The monitoring module is used to collect parameters of the wire supply device, which are recorded as wire parameters; and transmit the wire parameters to the control module; wherein, the wire parameters include wire temperature and wire tension.

[0010] Furthermore, the process of transmitting the line parameters to the control module includes: The microprocessor unit compares the line parameters with preset standard parameters and determines whether to correct the current speed of the drive motor based on the comparison result; if it determines that correction is needed, the current speed is corrected according to the line parameters.

[0011] Furthermore, when the microprocessor unit compares the line parameters with preset standard parameters and determines whether to correct the current speed of the drive motor based on the comparison result, it includes: The preset standard parameters include standard tension range and standard temperature; The temperature and tension of the production line are compared with the standard temperature and tension ranges, and the current speed of the drive motor is adjusted based on the comparison results.

[0012] Furthermore, when comparing the yarn temperature and yarn tension with standard temperature and standard tension ranges respectively, the following steps are included: If the tension of the line is within the standard tension range, the first comparison result is that the current speed of the drive motor does not need to be corrected. If the tension of the line is not within the standard tension range, the first comparison result is that the current speed of the drive motor needs to be corrected. If the temperature of the line body is less than or equal to the standard temperature, then the second comparison result is that the current speed of the drive motor does not need to be corrected. If the temperature of the production line is greater than the standard temperature, then the second comparison result is that the current speed of the drive motor needs to be corrected.

[0013] Furthermore, when determining whether to correct the current speed of the drive motor based on the two comparison results, the following steps are included: If the first comparison result and / or the second comparison result indicate that the current speed of the drive motor needs to be corrected, then it is finally determined that the current speed of the drive motor needs to be corrected. If the tension of the yarn is less than the minimum value of the standard tension range and the temperature of the yarn is greater than the standard temperature, the coaxial dual-wheel differential yarn supply device will be controlled to stop working. If the tension of the yarn is less than the minimum value of the standard tension range, and the temperature of the yarn is less than or equal to the standard temperature, then the output speed of the corresponding drive motor is reduced. If the tension of the yarn is greater than the maximum value of the standard tension range and the temperature of the yarn is greater than the standard temperature, then the output speed of the corresponding drive motor is reduced. If the tension of the yarn is greater than the maximum value of the standard tension range, and the temperature of the yarn is less than or equal to the standard temperature, then the output speed of the corresponding drive motor is increased.

[0014] Furthermore, when correcting the current rotational speed based on the line parameters, the following steps are included: If the tension of the yarn is less than the minimum value of the standard tension range, and the temperature of the yarn is less than or equal to the standard temperature, then the current rotational speed is corrected by the first correction factor. If the tension of the yarn is greater than the maximum value of the standard tension range, and the temperature of the yarn is greater than the standard temperature, then the current rotational speed is corrected by the second correction coefficient. If the tension of the yarn is greater than the maximum value of the standard tension range, and the temperature of the yarn is less than or equal to the standard temperature, then the current rotational speed is corrected by a third correction factor. The correction coefficient ranges from the second correction coefficient to the first correction coefficient to 1 to the third correction coefficient.

[0015] Furthermore, when correcting the current rotational speed based on the line parameters, the following steps are included: The corrected rotational speed is the product of the current rotational speed and the correction factor.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: By coaxially arranging the left and right frames on the power base and arranging multiple wire feeding devices between them, the entire coaxial dual-wheel differential wire feeding device is more compact, symmetrical, and stable in its structural layout, which helps to reduce the risk of vibration and off-center load during equipment operation; the several left threading drums arranged on the left frame correspond one-to-one with the wire feeding devices and are driven by independent drive motors, enabling independent speed control of each line during the wire feeding process, avoiding the problem of asynchronous wire feeding caused by load differences or wire diameter changes under the traditional single drive method, thereby improving the uniformity and reliability of multi-line parallel wire feeding; at the same time, the wire feeding device is arranged between the left and right frames, making the force path of the wire more reasonable during the wire feeding process. This design helps reduce the swaying of the cable in the lateral and radial directions, lowering the risk of cable wear and breakage. The cable guide cylinder and multiple cable guide wheels are located on the left side of the frame away from the right side, and are the same number as the cable feeding device. This ensures that each cable has an independent, clear, and stable guiding path during the cable feeding stage, effectively avoiding problems such as multiple cables crossing, tangling, or interfering with each other, further improving the controllability and safety of the cable feeding process. Furthermore, by configuring a corresponding drive motor for each left cable feeding cylinder, differential speed cable feeding control can be achieved without changing the overall mechanical structure. This provides a good hardware foundation for the subsequent introduction of intelligent adjustment and fine control of parameters such as tension and temperature. Therefore, this coaxial dual-wheel differential speed cable feeding device possesses comprehensive advantages such as simple structure, strong scalability, good adaptability, and stable operation.

[0019] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features in the embodiments of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] In some embodiments of this application, see Figure 1-2 As shown, this embodiment provides a coaxial dual-wheel differential cable supply device, including: Power base 100; A left frame 200 and a right frame 300 are respectively disposed on both sides of the upper part of the power base 100, and the left frame 200 and the right frame 300 are coaxially disposed; wherein, a plurality of left wire-threading cylinders 210 are disposed on the left frame 200. A plurality of wire feeding devices 400 are provided, and all of the plurality of wire feeding devices 400 are arranged between the left side frame 200 and the right side frame 300; wherein, the number of left threading tubes 210 is the same as that of wire feeding devices 400; The cable guide cylinder 500 and the cable guide wheel 600 are provided. The cable guide cylinder 500 is located on the side of the left frame 200 away from the right frame 300. Several cable guide wheels 600 are provided and are located on the side wall of the cable guide wheel 600 away from the right frame 300. The number of cable guide wheels 600 is the same as that of the cable feeding device 400. Several drive motors 700 are provided, and each drive motor 700 is connected to a left threading drum 210.

[0021] Understandably, by coaxially arranging the left side frame 200 and the right side frame 300 on the power base 100, and placing multiple wire feeding devices 400 between them, the entire coaxial dual-wheel differential speed wire feeding device becomes more compact, symmetrical, and stable in its structural layout, which helps reduce vibration and off-center load risks during equipment operation. Several left wire-threading drums 210 on the left side frame 200 correspond one-to-one with the wire feeding devices 400 and are driven by independent drive motors 700, enabling independent speed control of each wire line during the wire feeding process. This avoids the problem of asynchronous wire feeding caused by load differences or wire diameter variations under traditional single-drive methods, thereby improving the uniformity and reliability of multi-line parallel wire feeding. Simultaneously, the wire feeding devices 400, positioned between the left side frame 200 and the right side frame 300, make the force path of the wire more reasonable during the wire feeding process. This design helps reduce the swaying of the cable in the lateral and radial directions, lowering the risk of cable wear and breakage. The cable guide cylinder 500 and multiple cable guide wheels 600 are located on the left side of the left frame 200 away from the right frame 300, and are the same number as the cable feeding device 400. This ensures that each cable has an independent, clear, and stable guiding path during the cable feeding stage, effectively avoiding problems such as multiple cables crossing, tangling, or interfering with each other, further improving the controllability and safety of the cable feeding process. In addition, by configuring a corresponding drive motor 700 for each left cable feeding cylinder 210, differential speed cable feeding control can be achieved without changing the overall mechanical structure. This provides a good hardware foundation for the subsequent introduction of intelligent adjustment and fine control of parameters such as tension and temperature. Thus, this coaxial dual-wheel differential speed cable feeding device has comprehensive advantages such as simple structure, strong expandability, good adaptability, and stable operation.

[0022] Specifically, the wire feeding device 400 in this embodiment has the same structure as the wire feeding device 400 in CN115559143A: A wire feeding device for a double twisting machine, and the wire threading method of this application is also the same as the wire threading method in CN115559143A: A wire feeding device for a double twisting machine; only the configuration of the drive motor 700 is different.

[0023] In some embodiments of this application, the coaxial dual-wheel differential wire feeding device further includes a control module, which is connected to the drive motor 700 and is mounted on the power base 100. The control module is used to receive external control signals and independently adjust the output speed of each drive motor 700 to achieve a wire feeding speed difference between different wire feeding devices 400.

[0024] In some embodiments of this application, the control module includes: Microprocessor unit, speed sensor group and drive circuit unit; The speed sensor group is connected to each drive motor 700 in a one-to-one correspondence. The speed sensor group is used to collect the actual speed of the drive motor 700 in real time and feed it back to the microprocessor unit. The drive circuit unit is electrically connected to the microprocessor unit and each drive motor 700 respectively. The drive circuit unit is used to adjust the working current of the drive motor 700 according to the control command output by the microprocessor unit. The microprocessor unit compares and analyzes the target speed set by the external control signal with the actual speed fed back by the speed sensor group, and dynamically adjusts the output speed of each drive motor 700 through the drive circuit unit.

[0025] Understandably, by setting a control module in the coaxial dual-wheel differential cable feeding device and connecting this control module to each drive motor 700, each drive motor 700 can achieve independent speed regulation under a unified control architecture. This overcomes the limitations of traditional cable feeding devices where multiple cable feeding units are restricted to a single drive or simple mechanical linkage, effectively improving the flexibility and accuracy of multi-line cable feeding processes. The control module adopts a closed-loop control structure consisting of a microprocessor unit, a speed sensor group, and a drive circuit unit. The speed sensor group collects the actual speed of each drive motor 700 in real time and feeds it back to the microprocessor unit, enabling the microprocessor unit to compare the actual speed with external control signals. The system continuously compares and analyzes the set target speed and outputs precise control commands accordingly. The drive circuit unit dynamically adjusts the operating current of the drive motor 700, thereby achieving rapid response and stable control of the speed of each drive motor 700. This method not only effectively eliminates speed fluctuations caused by load changes, mechanical friction, or differences in line condition, improving the accuracy and consistency of line feeding speed control, but also provides a reliable guarantee for stable and controllable differential line feeding between different line feeding devices 400. At the same time, it helps reduce line tension fluctuations and operational shocks, reduces the risk of line breakage and wear, and further improves the operational stability, automation level, and adaptability to complex working conditions of the entire line feeding device.

[0026] In this embodiment, an industrial wire feeding device for synchronous feeding of multiple strands of fine wire is used as the application scenario. The coaxial dual-wheel differential speed wire feeding device is installed at the front end of the production line. Its power base 100 is fixed on the ground. The left side frame 200 and the right side frame 300 are respectively installed on the left and right sides of the upper part of the power base 100, and the two are coaxially arranged through the same central axis. Three sets of left threading drums 210 are evenly arranged on the left side frame 200, and three sets of feeding devices 400 are correspondingly arranged. The three sets of feeding devices 400 are arranged between the left side frame 200 and the right side frame 300. Each set of feeding devices 400 is used to carry one roll of wire to be fed. Each left threading drum 210 is connected to the corresponding drive motor 700 through a coupling. The drive motor 700 is fixedly installed inside the power base 100, forming an independent wire feeding channel structure of "one motor - one threading drum - one feeding device 400". An outlet is provided on the side of the left side frame 200 away from the right side frame 300. The cable guide cylinder 500 has three cable guide wheels 600 arranged sequentially along the circumference on its outer side. This allows the three cable lines to be discharged through their respective cable guide wheels 600 after cable laying, avoiding mutual interference. The control module is installed inside the power base 100. Its microprocessor unit is pre-set with seven target cable supply speeds and collects the actual speeds of each drive motor 700 in real time through a speed sensor group. When a speed deviation is detected in a cable line due to changes in cable diameter or increased load, the microprocessor unit immediately adjusts the operating current of the corresponding drive motor 700 through the drive circuit unit, thereby individually correcting the cable supply speed of that cable line without affecting the normal operation of other cable lines. Through the above structure and control method, differential, stable, and independent cable supply control of multiple cable lines is achieved under the premise of a basically consistent overall structure. This verifies the feasibility, stability, and practical value of this coaxial dual-wheel differential cable supply device in a real production environment.

[0027] In some embodiments of this application, the coaxial dual-wheel differential cable supply device further includes a monitoring module disposed on the cable supply device; The monitoring module is used to collect parameters of the wire supply device, which are recorded as wire parameters; and transmit the wire parameters to the control module; wherein, the wire parameters include wire temperature and wire tension.

[0028] In some embodiments of this application, transmitting the line parameters to the control module includes: The microprocessor unit compares the line parameters with preset standard parameters and determines whether to correct the current speed of the drive motor 700 based on the comparison result; if it determines that correction is needed, the current speed is corrected according to the line parameters.

[0029] In some embodiments of this application, when the microprocessor unit compares the line parameters with preset standard parameters and determines whether to correct the current speed of the drive motor 700 based on the comparison result, the following steps are included: The preset standard parameters include standard tension range and standard temperature; The temperature and tension of the production line are compared with the standard temperature and tension ranges, and the current speed of the drive motor 700 is adjusted based on the comparison results.

[0030] In some embodiments of this application, the comparison of the yarn temperature and yarn tension with standard temperature and standard tension ranges respectively includes: If the tension of the line is within the standard tension range, then the first comparison result is that the current speed of the drive motor 700 does not need to be corrected. If the tension of the line is not within the standard tension range, the first comparison result is that the current speed of the drive motor 700 needs to be corrected. If the temperature of the line body is less than or equal to the standard temperature, then the second comparison result is that the current speed of the drive motor 700 does not need to be corrected. If the temperature of the production line is greater than the standard temperature, then the second comparison result indicates that the current speed of the drive motor 700 needs to be corrected.

[0031] In some embodiments of this application, the step of determining whether to correct the current speed of the drive motor 700 based on two comparison results includes: If the first comparison result and / or the second comparison result indicate that the current speed of the drive motor 700 needs to be corrected, then it is finally determined that the current speed of the drive motor 700 needs to be corrected. If the tension of the yarn is less than the minimum value of the standard tension range and the temperature of the yarn is greater than the standard temperature, the coaxial dual-wheel differential yarn supply device will be controlled to stop working. If the tension of the yarn is less than the minimum value of the standard tension range, and the temperature of the yarn is less than or equal to the standard temperature, then the output speed of the corresponding drive motor 700 is reduced. If the tension of the yarn is greater than the maximum value of the standard tension range and the temperature of the yarn is greater than the standard temperature, then the output speed of the corresponding drive motor 700 will be reduced. If the tension of the yarn is greater than the maximum value of the standard tension range, and the temperature of the yarn is less than or equal to the standard temperature, then the output speed of the corresponding drive motor 700 is increased.

[0032] In some embodiments of this application, the step of correcting the current rotational speed based on line parameters includes: If the tension of the yarn is less than the minimum value of the standard tension range, and the temperature of the yarn is less than or equal to the standard temperature, then the current rotational speed is corrected by the first correction factor. If the tension of the yarn is greater than the maximum value of the standard tension range, and the temperature of the yarn is greater than the standard temperature, then the current rotational speed is corrected by the second correction coefficient. If the tension of the yarn is greater than the maximum value of the standard tension range, and the temperature of the yarn is less than or equal to the standard temperature, then the current rotational speed is corrected by a third correction factor. The correction coefficient ranges from the second correction coefficient to the first correction coefficient to 1 to the third correction coefficient.

[0033] In some embodiments of this application, the step of correcting the current rotational speed based on line parameters includes: The corrected rotational speed is the product of the current rotational speed and the correction factor.

[0034] Understandably, in this embodiment, by setting a monitoring module on the coaxial dual-wheel differential speed wire feeding device, real-time monitoring of key parameters of each route section—wire tension and wire temperature—is achieved, and the collected parameters are fed back to the control module. The microprocessor unit compares the real-time collected wire parameters with preset standard parameters, and determines whether the current speed of each drive motor 700 needs to be corrected based on the comparison result, thus achieving closed-loop control. By setting speed correction logic for different situations, such as increasing or decreasing the speed when the tension is too low, too high, or the temperature is abnormal, and by using different correction coefficients for dynamic adjustment, the tension and temperature of each route section can be maintained within a safe and stable range during the wire feeding process. This improves the uniformity and reliability of multi-wire parallel feeding, reduces the risk of wire wear, breakage, or tangling, and avoids the shutdown of the entire equipment due to a single path abnormality, thereby improving the safety, stability, and production efficiency of the wire feeding process.

[0035] In this specific embodiment, an industrial production line uses three parallel feed lines. The coaxial dual-wheel differential feed device is equipped with three monitoring modules to collect the temperature and tension parameters of the three feed lines. The microprocessor unit presets a standard tension range of 10–15 N and a standard maximum temperature of 80°C. When the tension of the first feed line is 9 N and the temperature is 75°C, it is determined that the tension is below the standard range, but the temperature is normal. A first correction coefficient of 0.95 is used to slightly reduce the current speed of the corresponding drive motor 700 to restore the tension to the standard range. When the tension of the second feed line is 16 N and the temperature is 85°C, both tension and temperature exceed the standard. The system uses a second correction coefficient of 0.9 to reduce the speed of the corresponding drive motor 700 to ensure safety. When the tension of the third feed line is 17 N and the temperature is 78°C, the tension exceeds the standard while the temperature is normal. A third correction coefficient of 1.05 is used to appropriately increase the speed to avoid feed lag. In this way, the three feed lines can achieve independent, dynamic, and intelligent differential speed control under different operating conditions, ensuring balanced and stable operation of the multi-line feed.

[0036] The standard tension range and standard temperature are set based on the material, diameter, process requirements, and safe operating range of the production line, defining a safe and stable operating range for wire supply. Correction coefficients are set according to different deviations. In principle, when the wire tension is below the standard range, the speed is slightly reduced (coefficient slightly less than 1); when the wire tension exceeds the standard, the speed is appropriately increased or decreased (coefficient greater than or less than 1); and when the temperature is too high, the speed is reduced to avoid overheating. By comparing actual parameters with preset standard values ​​and adjusting the motor speed according to the corresponding correction coefficients, closed-loop intelligent control can be formed, maintaining the wire tension and temperature of each line within a reasonable range, achieving dynamic stability and safety in the wire supply process.

[0037] Specifically, the standard tension range is set based on the physical properties of the material used in the production line (such as elastic modulus and tensile strength), wire diameter specifications, specific process requirements (such as winding density and tension standards), and safe operating range. Its function is to define a safe tension range within which the wire can maintain a stable shape during the supply process, avoiding excessive stretching or slack. This ensures that the wire will not tangle or accumulate due to insufficient tension, nor will it break or wear excessively due to excessive tension. The standard temperature is set based on the heat resistance parameters of the wire material (such as melting point and heat distortion temperature), long-term thermal stability requirements, and the maximum allowable temperature of the equipment's operating environment. It is mainly used to define a safe temperature threshold that will prevent material degradation, strength reduction, or insulation damage due to excessively high temperatures during the supply process, preventing irreversible damage to the equipment and the wire due to abnormal temperatures.

[0038] Furthermore, the first correction factor is set based on the degree of deviation when the cable tension is lower than the minimum standard tension range and the cable temperature is less than or equal to the standard temperature, as well as the cable's sensitivity to speed changes. Its value is slightly less than 1 (e.g., 0.95 in the example). The purpose is to reduce the cable unwinding speed by slightly decreasing the output speed of the drive motor (700 rpm), thereby gradually restoring the cable tension to the standard range. The correction magnitude must ensure a smooth adjustment process to avoid excessive tension fluctuations due to a sudden drop in speed. The second correction factor is set based on the dual abnormal situation when the cable tension is greater than the maximum standard tension range and the cable temperature is greater than the standard temperature. Considering that excessively high temperatures pose a threat to cable safety, a significant reduction in speed is needed to simultaneously alleviate both excessive tension and high temperature. Therefore, its value is less than the first correction factor (e.g., 0.9 in the example) to achieve a more significant speed reduction effect, prioritizing the operational safety of the equipment and the cable. The third correction factor is set based on the degree of tension deviation and the load-bearing capacity of the yarn when the yarn tension is greater than the maximum value of the standard tension range and the yarn temperature is less than or equal to the standard temperature. Its value is greater than 1 (such as 1.05 in the example). By appropriately increasing the output speed of the drive motor 700, the yarn unloading speed is accelerated, thereby reducing the tension on the yarn and bringing it back to the standard range. The correction range needs to take into account both the tension adjustment efficiency and the smoothness of the yarn operation, and avoid excessive increase in speed causing new problems.
