F500A High Speed Rewinding Machine Features
Precision electronic control system
Film Rewinder Machine adopts German SIEMENS SIMATIC S7-1500 motion controller for centralized management, with multi-axis coordinated response capability within 0.1 seconds, and can stably handle complex tension switching and synchronous control under high-speed operation, significantly reducing the risk of material deviation or deformation caused by electronic control delay.
Efficient servo drive configuration
Film Rewinder Machine is equipped with German SIEMENS SINAMICS servo drive system, with a main drive power of up to 7.5kW and an auxiliary drive system response speed of less than 20ms. During the unwinding and rewinding process of the entire roll of 800mm diameter material, the line speed and tension are still synchronized, improving the consistency of the final product.
Low-tension precision control
The Film Rewinder Machine is equipped with a low-tension sensor system designed for thin and light materials, which can achieve automatic tension adjustment from 5N to 80N. Whether it is BOPP, CPP film or light paper, it can ensure no deformation and wrinkling, especially suitable for packaging customers who have high requirements for the flatness of the edge of the roll.
Stable correction and positioning system
The Film Rewinder Machine adopts the German BST frame-type photoelectric correction system, with a correction repeatability of ±0.1mm. The system supports real-time tracking and correction of the substrate edge, printing reference line, punching position, etc., to ensure that the roll maintains the correct trajectory during high-speed operation and effectively avoids rewinding and misalignment.
Flexible switching of two-way operation
The Film Rewinder Machine has a forward/reverse operation switching function with a switching time of less than 1.5 seconds. This design facilitates the rapid reversal of the material path during defect correction, repeated inspection, and trimming operations, shortens the manual intervention time, and improves the overall process adaptation capability and processing efficiency.
Applied in the food packaging workshop of TPBI Group in Thailand
The F500A Film Rewinder Machine is deployed at the end of TPBI's CPP heat-sealing film production line. Through the high-speed rewinding function, the large roll of the mother roll is accurately cut into multiple specifications of finished products for sale. With the help of the optional pattern fixed length detection system, the printed pattern and the slitting size are strictly matched to meet the requirements of international food packagers.
Applied in Ningbo Asia Paper Co., Ltd. in China
Asia Paper uses Film Rewinder Machine to rewind waxed paper and silicone paper at the end, and avoids surface damage and lamination deviation through a low tension control system. The Film Rewinder Machine realizes continuous operation and uninterrupted switching, significantly reducing the time for changing workstations and improving the efficiency of the order fulfillment cycle.
Applied to the post-printing processing of PT Argha Karya Prima in Indonesia
PT Argha configures the Film Rewinder Machine in the rewinding quality inspection section of PET printed film, and combines it with the online defect detection system to automatically identify and locate problems such as missing printing and ghosting. With the reverse operation function, defects are eliminated in time, and the final product qualification rate is increased to 99.2%.
F500A High Speed Rewinding Machine Care and Maintenance
Daily cleaning of the photoelectric correction system
Use low-dust cloth to wipe the surface of the BST sensor head every day to prevent ink residue and dust coverage from affecting the detection accuracy. Use a special test strip to detect the correction response curve every two weeks to ensure that the system sensitivity and speed remain within the technical standard range.
Tension detection and calibration
Perform a tension sensor calibration once a month to ensure that the low tension reading accuracy is within ±3N. Especially for the application scenario of lightweight film materials, the upper and lower limits of tension should be set in advance before changing the roll to prevent uneven tension problems in the starting or ending stage.
Stability inspection of the electronic control system
Arrange technicians to check the operating status of all drive lines, power modules and communication ports in the SIEMENS control cabinet every quarter. The system should maintain a temperature below 30°C and humidity below 65%RH to ensure that the Film Rewinder Machine can operate continuously and stably in a high-intensity operating environment.
Lubrication and inspection of sliding components
For key parts such as the unwinding tensioning shaft, guide rollers, and knife holder crossbeams, it is recommended to use high-temperature wear-resistant lubricating oil for maintenance every 100 hours of operation to prevent sliding obstruction, gear wear, or reduced control accuracy due to dry friction.
