Film Roll Slitting Rewinding Machine is an efficient and precise film slitting and rewinding equipment. It adopts an overall closed frame structure. The machine body is mainly composed of an automatic unwinding unit, a CCD guide correction system, a cutter assembly, a differential pressure control roller, a slip axis double rewinding mechanism and an electric control cabinet. It is supported by a high-strength welded steel structure and equipped with a large-size touch operation panel. It is widely used in the fields of disposable sanitary products and soft packaging material processing.

Intelligent control - German SIEMENS SIMATIC integrated system

Film Roll Slitting Rewinding Machine uses German Siemens high-end SIMATIC motion controller to centrally manage various modules, which can realize multi-axis linkage, tension adjustment, correction control and other functions. The control system responds faster than 1ms, ensuring that cutting accuracy and synchronization stability can be maintained even at a high-speed operation of 600m/min.

Precision drive - full set of SIEMENS servo system configuration

The drive system uses a full range of German Siemens servo motors and drivers to achieve closed-loop control of the entire process from unwinding, correction to rewinding. With servo tension feedback, the output torque can be automatically adjusted according to the material thickness, and it is suitable for a variety of plastic films, papers and other different substrates.

High-precision correction - imported CCD guide control

Film Roll Slitting Rewinding Machine is equipped with an imported CCD optical correction system, which automatically identifies the film edge, printed markings or transparent positioning patterns to achieve ±0.05mm correction accuracy. It is particularly suitable for high-precision continuous positioning cutting of transparent films and printed films such as PE and BOPP.

Fine rewinding - slip axis and automatic pressure difference control

Film Roll Slitting Rewinding Machine adopts a low-tension slip axis rewinding system, combined with pressure difference to automatically control the rewinding roller, even under the condition of the minimum slitting width of 50mm, it can achieve a flat, wrinkle-free and loose roll effect. The maximum rewinding diameter is Φ1000mm, which is suitable for long-term continuous operation.

High compatibility - multi-material high-speed slitting adaptation

Film Roll Slitting Rewinding Machine supports slitting of various materials such as OPP, CPP, PE, PET, PVC, NY, paper, etc., with a maximum width of 2500mm, a cutting speed of up to 600m/min, and a slitting width range of 50-1200mm, which can meet the needs of various industrial-grade orders.

Environmentally friendly design - online edge trimming and recycling

Film Roll Slitting Rewinding Machine is equipped with a film edge trimming device and an automatic waste edge recycling system. Without affecting the reeling of the main material, it automatically cuts off the burrs and rolls them into an independent recycling reel, effectively saving labor, improving material utilization, and being environmentally friendly and efficient.

1. Adult Incontinence Film Processing

The automatic air-shaft high-speed slitting machine is widely applied in adult hygiene product production. Windeed integrates this solution to slit breathable backsheet films for adult incontinence pads, ensuring uniform roll width, smooth edges, and stable tension control, which improves both product quality and line efficiency.

2. Sanitary Napkin Film Slitting

Qifeng applies the machine to sanitary napkin film processing, where high precision is essential for thin and delicate materials. The equipment ensures accurate slitting without damaging the film structure, supporting consistent large-scale production of feminine hygiene products.

3. Baby Pants Laminate Processing

Xinqi leverages the air-shaft slitting machine for baby training pants laminate films. The machine provides excellent roll alignment and cutting accuracy, reducing material waste and ensuring high productivity in continuous operations.

Cleaning optical components and cutters

After daily operation, the CCD lens, guide rollers and cutter blades should be cleaned with a dust-free cloth to prevent residual film dust from blocking the optical path or tool wear and failure. It is recommended to spray the main operating area with an anti-static treatment agent every week to ensure that the components are clean.

Regular inspection and grinding

Depending on the film material and operating frequency, the tool edge should be checked every 20,000 to 30,000 meters of operation. If the circular knife or flat knife is found to have burrs or wire drawing on the cut, it should be ground or replaced in time to keep the cutting edge neat.

Maintenance of light-sensing components

Check the sensitivity of the CCD deflection correction system and the lens alignment angle once a month. If deviation or inaccurate recognition is found, it should be recalibrated with a ruler to ensure high-precision line tracking capability.

Calibration of the slip axis tension system

It is recommended to calibrate the tension feedback module for zero point and linearity every three months, especially when the material is frequently changed. Calibration can ensure that the system quickly adapts to the tension characteristics of the new material to avoid film breakage or loose winding caused by tension fluctuations.

Electrical system inspection

Electricians need to check the Siemens drive, cable connectors and power modules every quarter to confirm that the voltage is stable and the port is not aged. It is recommended that the equipment be equipped with a voltage stabilizer and a lightning protection module to avoid damage to the control board caused by sudden voltage fluctuations.
