Preferably, the integrated winch is connected to a set of axisymmetric custom tension sensors; the custom tension sensors are connected to anti-slip wire guide wheels.
[0008] Preferably, the supporting hollow shaft is equipped with an electrical signal transmission module for transmitting electrical signals from a customized tension sensor. Preferably, the precision tension control stranding unit further includes a stranding motor and a drive shaft. One end of the drive shaft is connected to a pulley, and the other end is fixed to the main support frame via a support bearing seat and passes through the main support frame, connecting to the main shaft of the stranding motor via an electronic clutch. The pulley is connected to an integrated winch via a synchronous belt.

[0010] Preferably, the vacuum dust removal unit is mounted on a vacuum dust removal unit bracket and includes a negative pressure suction nozzle, a dust filter, a negative pressure generator, and a compressed air solenoid valve.

The negative pressure port of the negative pressure generator is connected to the outlet of the dust filter via a transmission pipe, and the inlet of the dust filter is connected to the negative pressure suction nozzle via a transmission pipe.
[0011] Preferably, the electrical control system is installed on the equipment push handle bracket, and includes an industrial control panel and a PLC control module. The industrial control panel and the PLC control module are electrically connected. The PLC control module is electrically connected to the magnetic powder tensioner and the electronic clutch.
[0012] A method for operating a multifunctional precision tension control stranding system for cable bundling, characterized by the following steps: (1) When the device selects the passive twisted wire mode: Step 1: The industrial control panel transmits the passive stranding electrical signal to the PLC control module. The PLC control module transmits the electronic clutch closing electrical signal to the electronic clutch. The closing of the electronic clutch ensures that the drive shaft of the precision tension control stranding and unwinding unit is in an unloaded state (cutting off the motor resistance), realizing the passive stranding mode. In this mode, the equipment only adjusts the unwinding tension. Step 2, the specific steps of this system in passive twisted wire mode are as follows: 2.1 The user installs the stranded wire onto the corresponding stranded wire fixing seat, passes the exposed end of the stranded wire through the anti-slip wire guide wheel on either side, and pulls it to the cable core to be stranded on the main production line and secures it with tape. 2.2 Vacuum dust removal unit startup: After the equipment is powered on, the PLC control module will send an electrical signal to the compressed air solenoid valve of the vacuum dust removal unit, which will introduce the compressed air source into the air inlet of the vacuum generator through the transmission air pipe, generating negative pressure. The negative pressure port of the negative pressure generator is connected to the air outlet of the dust filter through the transmission air pipe, and the air inlet of the dust filter is connected to the negative pressure suction nozzle through the transmission air pipe, so as to ensure that the vacuum dust removal unit is in working condition as soon as the equipment is turned on. 2.3 Precision tension control stranding unit starts. After the equipment is powered on, the customized tension sensor transmits the real-time monitoring electrical signal of the stranded wire tension to the PLC control module through the electrical signal transmission module. The PLC control module first transmits the calculated real-time stranded wire tension value to the industrial control screen through the real-time stranded wire tension electrical signal to realize the real-time display of the stranded wire tension. At this time, the operator sets the tension setpoint on the industrial control screen. The industrial control screen sends the set stranded wire tension electrical signal to the PLC control module. When the PLC control module internally calibrates the actual stranded wire tension value against the setpoint, it adjusts the tension electrical signal in real time and sends it to the tension controller. The tension controller outputs the adjusted power to the magnetic powder tensioner to achieve linear tension control. When the actual tension is greater than the set tension, the PLC control module controls the tension controller to reduce the output power voltage, and the tension provided by the magnetic powder tensioner decreases. When the actual tension is less than the set tension, the PLC control module controls the tension controller to increase the output power voltage, and the tension provided by the magnetic powder tensioner increases. The stranding action of the stranded wire is driven by the traction force of the main production line equipment. (2) When the equipment needs to select the active twisted wire mode: Step 1: After the equipment is powered on, select the corresponding active twisting mode on the industrial control screen. The industrial control screen will transmit the active twisting electrical signal to the PLC control module. The PLC control module will transmit the start electrical signal to the electronic clutch to ensure that the twisting motor can drive the drive shaft. Step 2, the specific steps of this system in active twisted wire mode are as follows: 2.1 The user installs the stranded wire onto the corresponding stranded wire fixing seat, passes the exposed end of the stranded wire through the anti-slip wire guide wheel on either side, and pulls it to the cable core to be stranded on the main production line and secures it with tape. 2.2 Vacuum dust removal unit startup: After the equipment is powered on, the PLC control module will open the solenoid valve of the vacuum dust removal unit to transmit the electrical signal, and introduce the compressed air source into the air inlet of the vacuum generator through the transmission air pipe to generate negative pressure. The negative pressure port of the negative pressure generator is connected to the air outlet of the dust filter through the transmission air pipe, and the air inlet of the dust filter is connected to the negative pressure suction nozzle through the transmission air pipe to ensure that the vacuum dust removal unit is in working condition as soon as the equipment is turned on. 2.3 Precision Tension Control Stranding Unit Start-up: After the equipment is powered on, the customized tension sensor transmits the real-time detected strand tension electrical signal to the PLC control module via the electrical signal transmission module. The PLC control module first transmits the calculated real-time strand tension value to the industrial control screen via the real-time strand tension electrical signal, realizing real-time display of the strand tension. At this time, the operator inputs the set strand tension on the industrial control screen, and the industrial control screen sends the set strand tension electrical signal to the PLC. When the PLC internally calibrates the actual strand tension value against the set value, it sends a real-time tension adjustment electrical signal to the tension controller. The tension controller outputs the adjusted power to the magnetic powder tensioner to achieve linearity. Tension control; simultaneously, the main production line transmits the real-time production speed electrical signal to the PLC control module of this system. The PLC control module transmits the real-time production speed electrical signal to the industrial control screen. The industrial control screen, through internal calculation and verification, sends the real-time set stranding speed signal to the PLC control module. The PLC control module sends the real-time set stranding speed electrical signal to the frequency converter controlling the stranding motor. The frequency converter outputs power to the stranding motor, and through the variable frequency power output of the frequency converter, it precisely controls the rotation of the stranding motor. The rotation of the stranding motor drives the drive shaft to rotate, and then drives the integrated winch through the synchronous belt drive, thereby realizing the stranding action of the strand.
[0013] Compared with existing technologies, it has the following beneficial effects: The precision tension control stranding unit uses a high-precision magnetic powder tensioner, which provides stable and accurate control. Furthermore, thanks to the use of a custom strand tension sensor, the unit achieves closed-loop tension control through real-time monitoring of the strand tension, truly ensuring precise tension control.
[0014] The portable rack unit has a compact structure and a dual-mode caster wheel structure at the bottom (fixed and movable). It is also equipped with a push handle, making it very convenient to temporarily attach the equipment between units and easily achieve borrowing and installation.
[0015] The vacuum dust removal unit has a novel structure. It uses a negative pressure suction nozzle to adsorb and transfer dust to a dust filter bag. The dust filter bag can be disassembled and cleaned periodically (dust is discharged in a fixed position). The components of the unit have a simple structure and reliable performance.
[0016] The electrical control system is rationally distributed, advanced in design, rich in functions, and has a clear interaction. It perfectly realizes the electrical control actions of each unit and has an open interface for the intelligent main production line.
[0017] This system can achieve lossless switching between active and passive stranding. For the first time, this system has added a dust adsorption function to daily use, which improves the environmental friendliness of the equipment. Attached Figure Description

A vacuum dust removal unit bracket 23 is connected to one side of the main support frame, and a motor support plate 24 and a device push handle bracket 25 are connected to the opposite side.
[0022] In this embodiment, the rectangular base plate is equipped with height-adjustable support wheels 26 at the four corners of the bottom, which can switch between fixed mode (working mode) and mobile mode (in fixed mode, the support columns of the support wheels are raised and the four mobile wheels are suspended in the air; in mobile mode, the support columns are retracted and the four mobile guide wheels are in contact with the ground). The equipment push handle is connected to the lower right of the main support column by welding. When the equipment needs to be moved, the support wheels are switched to mobile mode, the power and signal lines are disconnected, and the entire set of equipment can be moved directly by pushing the equipment push handle, which makes the equipment highly portable and convenient for use by various equipment in the workshop.
[0023] In this embodiment, the precision tension control stranding unit 1 includes a strand fixing seat 11, a magnetic powder tensioner 12, a supporting hollow shaft 13, and an integrated winch 14. The integrated winch 14 is fixed to the supporting hollow shaft 13 by bearings and shaft retaining springs. One end of the supporting hollow shaft is fixedly connected to the main support frame 21, and the other end is connected to the magnetic powder tensioner 12. One end of the strand fixing seat 11 is inserted into the magnetic powder tensioner 12 and fixed by locking screws.

[0025] In this embodiment, the precision tension control stranding unit 1 also includes a stranding motor 5 and a drive shaft 6. One end of the drive shaft is connected to a pulley 7, and the other end is fixed to the main support frame through a support bearing seat 8 and passes through the main support frame and is connected to the main shaft of the stranding motor through an electronic clutch 9. The pulley is connected to the integrated winch 14 through a synchronous belt 10.
[0026] In this embodiment, the stranded wire motor 5 is mounted on the motor support plate 24, and the stranded wire motor is connected to a frequency converter 27 for controlling the motor speed.
[0027] In this embodiment, the magnetic powder tensioner supports a constant tension output of 0.5N-10N and detects the real-time tension of the stranded wire using a customized stranded wire tension sensor. This real-time tension is transmitted to the PLC control module via an electrical signal. The PLC module then transmits the real-time data to an industrial control display screen. The industrial control screen sends a tension control electrical signal to the PLC according to the set tension value.

When the equipment is started, the PLC issues a solenoid valve opening command, and compressed air enters the vacuum generator to generate negative pressure. Through the connection of the transmission pipe, the negative pressure is finally transmitted to the negative pressure suction nozzle to achieve a full-time adsorption function. This ensures that during the equipment's twisting process, dust caused by pulling and wear is adsorbed by the negative pressure suction nozzle to the dust filter, greatly improving the on-site environment and demonstrating the equipment's excellent environmental performance.

Moreover, this industrial control screen supports various network protocols and can be connected to various network devices, and supports access to the intelligent factory monitoring system.
[0030] This invention also discloses a control method for a multifunctional precision tension control stranded wire system for cable bundling, comprising the following steps: (1) When the device selects the passive twisted wire mode: Step 1: The industrial control panel transmits the passive stranding electrical signal to the PLC control module. The PLC control module transmits the electronic clutch closing electrical signal to the electronic clutch. The closing of the electronic clutch ensures that the drive shaft of the precision tension control stranding and unwinding unit is in an unloaded state (cutting off the motor resistance), realizing the passive stranding mode. In this mode, the equipment only adjusts the unwinding tension. Step 2, the specific steps of this system in passive twisted wire mode are as follows: 2.1 The user installs the stranded wire onto the corresponding stranded wire fixing seat, passes the exposed end of the stranded wire through the anti-slip wire guide wheel on either side, and pulls it to the cable core to be stranded on the main production line and secures it with tape. 2.2 Vacuum dust removal unit startup: After the equipment is powered on, the PLC control module will send an electrical signal to the compressed air solenoid valve of the vacuum dust removal unit, which will introduce the compressed air source into the air inlet of the vacuum generator through the transmission air pipe, generating negative pressure.

After the equipment is powered on, the customized tension sensor transmits the real-time monitoring electrical signal of the stranded wire tension to the PLC control module through the electrical signal transmission module. The PLC control module first transmits the calculated real-time stranded wire tension value to the industrial control screen through the real-time stranded wire tension electrical signal to realize the real-time display of the stranded wire tension. At this time, the operator sets the tension setpoint on the industrial control screen. The industrial control screen sends the set stranded wire tension electrical signal to the PLC control module. When the PLC control module internally calibrates the actual stranded wire tension value against the setpoint, it adjusts the tension electrical signal in real time and sends it to the tension controller. The tension controller outputs the adjusted power to the magnetic powder tensioner to achieve linear tension control. When the actual tension is greater than the set tension, the PLC control module controls the tension controller to reduce the output power voltage, and the tension provided by the magnetic powder tensioner decreases. When the actual tension is less than the set tension, the PLC control module controls the tension controller to increase the output power voltage, and the tension provided by the magnetic powder tensioner increases. The stranding action of the stranded wire is driven by the traction force of the main production line equipment. (2) When the equipment needs to select the active twisted wire mode: Step 1: After the equipment is powered on, select the corresponding active twisting mode on the industrial control screen. The industrial control screen will transmit the active twisting electrical signal to the PLC control module. The PLC control module will transmit the start electrical signal to the electronic clutch to ensure that the twisting motor can drive the drive shaft. Step 2, the specific steps of this system in active twisted wire mode are as follows: 2.1 The user installs the stranded wire onto the corresponding stranded wire fixing seat, passes the exposed end of the stranded wire through the anti-slip wire guide wheel on either side, and pulls it to the cable core to be stranded on the main production line and secures it with tape. 2.2 Vacuum dust removal unit startup: After the equipment is powered on, the PLC control module will open the solenoid valve of the vacuum dust removal unit to transmit the electrical signal, and introduce the compressed air source into the air inlet of the vacuum generator through the transmission air pipe to generate negative pressure.

At this time, the operator inputs the set strand tension on the industrial control screen, and the industrial control screen sends the set strand tension electrical signal 3 to the PLC. When the PLC internally calibrates the actual strand tension value against the set value, it sends the real-time adjustment tension electrical signal to the tension controller. The tension controller outputs the adjusted power to the magnetic powder tensioner to achieve linearity. Tension control; simultaneously, the main production line transmits the real-time production speed electrical signal to the PLC control module of this system. The PLC control module transmits the real-time production speed electrical signal to the industrial control screen. The industrial control screen, through internal calculation and verification, sends the real-time set stranding speed signal to the PLC control module. The PLC control module sends the real-time set stranding speed electrical signal to the frequency converter controlling the stranding motor. The frequency converter outputs power to the stranding motor, and through the variable frequency power output of the frequency converter, it precisely controls the rotation of the stranding motor. The rotation of the stranding motor drives the drive shaft to rotate, and then drives the integrated winch through the synchronous belt drive, thereby realizing the stranding action of the strand.
[0031] This system's control method enables seamless switching between active and passive stranding. For the first time in daily use, it incorporates a dust adsorption function, improving the equipment's environmental friendliness. To move the equipment to the cabling production line where additional strands are needed (before moving, ensure the external power supply and signal lines are removed and the four bottom casters are set to moving mode), connect the power and signal lines. Based on the order's process requirements, select active or passive stranding mode on the control panel, set the strand tension, install the strands onto the strand fixing base, and pass the strand end through the anti-skid guide wheel on the customized tension sensor. Wrap the strand around the core passing through the hollow shaft and press the start button. The system automatically completes the stranding of the new strands, achieving intelligent operation. Its closed-loop tension control system provides more precise tension control; its lightweight structure offers excellent portability for easy workshop use; and its negative pressure dust removal unit essentially eliminates dust generated during stranding, improving the equipment's environmental friendliness. It offers a multi-functional option for both active and passive stranding.
