Surface Center Winding Machine Features
Intelligent centralized control system
Breathable Film Winding Machine adopts German SIEMENS SIMATIC high-end motion controller for centralized control, with multi-axis synchronous operation capability and high-speed real-time data processing function. The equipment can run at a maximum speed of 600m/min, and the operation response time is ≤ 0.5 seconds, ensuring that the coil is always in a stable winding state at high speed.
Efficient servo drive system
Breathable Film Winding Machine is equipped with a complete German SIEMENS servo drive system, which continuously and adaptively adjusts the unwinding tension, winding line speed, and coil diameter change. The maximum roll diameter is Φ1200mm, and the tension error is controlled within ±1.5N, which effectively ensures neat winding and consistent density.
Pre-drive mode improves roll changing efficiency
Breathable Film Winding Machine adopts the "preparatory shaft pre-drive mode". When the main reel has not completed winding, the spare reel can be rotated to the synchronous speed in advance to ensure that the roll changing time is shortened to less than 3 seconds. It effectively reduces downtime and is suitable for continuous and uninterrupted production lines.
Synchronous flexible winding method
The Breathable Film Winding Machine adopts "flexible synchronization" control during operation, and the angular velocity difference between the main reel and the spare reel is controlled within ±0.2rad/s to prevent excessive stretching or wrinkling of the material. This structure is particularly suitable for the stable winding of uneven thickness or composite film breathable film materials.
Low-loss material connection mode
Breathable Film Winding Machine is equipped with an automatic shearing device and a synchronous roll changing roller mechanism to automatically complete cutting and bonding without reducing speed. The length of material joint waste is controlled at ≤0.5m, saving 15%-20% of materials compared with the traditional robot roll changing method.
Can replace the original winding system
Breathable Film Winding Machine supports modular transformation, adapts to most breathable film equipment or cast film production lines, can directly replace the original backward winding unit, and supports docking with automatic feeding tracks and ERP systems. The maximum material width supports 2200mm, which improves the efficiency of the original production line by more than 30%.
Applied to the Quanzhou factory of China Hengan Group
In the breathable back film production line of Hengan Group, Breathable Film Winding Machine replaces the original domestic winding module to achieve efficient double-station switching. After the replacement, the daily material waste decreased by 12%, and the roll changing time was shortened to 1/4, which was highly praised by the engineering department.
Applied to Turkey Hayat Kimya maternal and child product line
Hayat Kimya, a well-known Turkish home care products company, introduced Breathable Film Winding Machine at its Istanbul production base for automatic end winding of baby diaper back film production. The equipment has a stable operating speed of 550m/min and supports 24-hour continuous operation, significantly reducing labor costs.
Applied to Unicharm Breathable Film Production Line in Vietnam
The Unicharm factory in Vietnam uses this equipment as the terminal winding unit of the breathable film cast line. With its high-speed switching and flexible synchronization technology, it has successfully achieved a daily output of more than 18 tons/line, becoming an important part of its transformation plan to introduce an "unmanned workshop".
Applied to DSG Factory in Thailand
DSG, a leading local sanitary product manufacturer in Thailand, introduced Breathable Film Winding Machine as the post-processing equipment for its adult diaper materials. The online bonding and pre-drive switching functions of Breathable Film Winding Machine enable it to maintain a roll change error of no more than ±5mm in multiple specifications of alternating orders, improving flexible production capacity.
Surface Center Winding Machine Care and Maintenance
Regular inspection of drive system
The servo motor and drive module need to be checked for operating status every month, including temperature rise monitoring, bearing lubrication and overload protection testing. It is recommended to replace the motor shaft end grease every 2000 hours to avoid response delays or torque abnormalities due to high temperature operation.
Control system software update and log record
SIEMENS SIMATIC controllers are recommended to perform data backup and firmware upgrades through authorized software every quarter to ensure stable operation of the control program. The operation log is exported once a week to analyze the roll change frequency, speed fluctuations and abnormal shutdown records to improve management efficiency.
Maintenance of pressure rollers and knives
The surface hardness and elasticity changes of the bonding pressure roller should be tested every 500 hours of use to prevent uneven bonding due to aging; the automatic scissors need to be sharpened or the blades replaced every 1000 cuts to ensure that the cutting surface is neat and without burrs.
Calibration of the correction and sensing system
It is recommended to perform a comprehensive calibration of the correction sensor, position encoder and tension feedback device every six months. The calibration standard refers to the ±0.1mm accuracy range, and uses standard coils as test samples to ensure sensitive correction response and accurate tension sensing.
