Cable Pay-Off & Take-Up Machine

What are the main structural components of a Cable Pay-Off & Take-Up Machine?

Core Structural Components of a Cable Pay-Off & Take-Up Machine:

1. High-Strength All-Steel Frame and Base: Utilizing a combination of bent and welded all-steel plates and rectangular steel tubing, the frame undergoes aging treatment to ensure rigidity and durability.

The base features a reinforced base plate with anti-slip pads, effectively resisting impacts and vibrations during operation.

2. Power and Transmission System: The main drive employs a closed-loop AC motor control with frequency converter speed regulation, achieving dynamic tension adjustment from 10-500N.

The transmission uses a high-precision gearbox or hardened gear reducer, providing high torque and low-noise drum rotation.

3. Tension Control and Measurement Unit: Employing a closed-loop tension sensor and PLC control, it achieves real-time tension monitoring and automatic compensation, ensuring uniform winding and stable tension.

Supports spool sizes from ϕ500-ϕ1250mm, compatible with copper, aluminum, and composite conductor materials.

4. Drum and Rewinding Mechanism
The dual-drum design, equipped with a shaftless opening and closing slot structure, allows for drum loading and unloading without the need for a crane.

The automatic drum loading/unloading mechanism, in conjunction with a PLC, enables 24-hour continuous operation, significantly reducing rewinding time.

5. Control Cabinet and HMI
Utilizing Siemens/Danfoss frequency converters and a touchscreen, it supports parameter setting, fault display, and remote monitoring.

How are rapid and automatic rewinding functions achieved?

Implementation Path for Rapid and Automatic Rewinding Functions

1. Shaftless Opening and Closing Slot and Cross-Layout of Dual Drums
The shaftless opening and closing slot structure, combined with a cross-layout of dual drums, enables rapid sliding in and out of the drums without the need for additional lifting equipment.

2. Automatic Drum Loading and Unloading Mechanism
Through a hydraulic or pneumatic lifting platform, in conjunction with positioning guide rails, the mechanism achieves automatic gripping, positioning, and locking of the drums, completing a "one-click rewinding change."

This device is fully integrated with the PLC, automatically calibrating tension parameters after roll change to ensure the next roll immediately enters a stable production state.

3. Collaborative Operation of PLC and Closed-Loop Control
The roll change command is issued by the PLC. The system automatically stops winding, switches drives, calibrates tension, and starts the new roll.

By monitoring the roll position sensor in real time, precise alignment during the roll change process is ensured, avoiding tension fluctuations caused by errors.

4. Example of Advantages in Roll Change Time
After adopting the above automation solution, roll change time can be shortened from the traditional 10-15 minutes to 2-3 minutes, achieving efficient 24-hour continuous operation.

How are machine safety protection measures configured?

Machine Safety Protection Measures Configuration Scheme

1. Overload Protection and Fault Warning
The frame has a built-in overload protection device, which, in conjunction with the tension sensor, monitors in real time. If the load exceeds the set range, the machine automatically stops and an alarm is triggered.

The control cabinet is equipped with fault indicator lights and audible and visual alarms, allowing operators to detect and handle abnormalities immediately.

2. Emergency Stop and Safety Door Interlock
Equipped with E-Stop buttons located at key positions on the control panel and machine body, meeting IEC 60204-1 safety standards.

Safety doors or protective covers are equipped with interlock switches; the system automatically stops operation when the door is not closed, preventing personnel from accidentally entering hazardous areas.

3. Pneumatic/Hydraulic Braking System
Utilizes a pneumatic brake valve for rapid braking during shutdown or emergency stop, preventing secondary injuries caused by the drum's inertial rotation.

4. Maintenance Early Warning and Periodic Inspection

The PLC records the operating time and temperature of critical components, automatically prompting maintenance when preset thresholds are reached.

Modular design facilitates quick replacement of worn parts, reducing maintenance downtime.
