Automatic Roll Slitter is a high-speed slitting equipment specially used for hot air non-woven fabrics and other flexible roll materials. It has the functions of automatic unwinding, precise deviation correction, synchronous slitting and efficient rewinding.

Intelligent centralized control | Accurate and efficient operation

The full set of Automatic Roll Slitter is centrally managed by the German SIEMENS SIMATIC high-end motion controller, and is equipped with a complete SIEMENS servo drive system to achieve high-speed synchronous linkage of various parts in the equipment. It supports a maximum operating speed of 300m/min, and the error is controlled within ±0.2mm throughout the process to ensure high-precision cutting.

Wide-width material support | Adapt to large roll material processing

Automatic Roll Slitter provides two models with an effective width of 2200mm to 3800mm, which is suitable for large-size hot air non-woven fabric slitting, with a maximum unwinding diameter of Φ1500mm and a maximum rewinding diameter of Φ1000mm, which is particularly suitable for the mass production needs of manufacturers of sanitary products and medical materials.

CCD deflection correction and guidance | Smooth operation of substrate

Automatic Roll Slitter is equipped with imported CCD image recognition and deflection correction system, which can identify material edges or printed logos in real time through visual signals, with an error adjustment accuracy of ±0.1mm, which can effectively avoid material deviation and serpentine trajectory, and ensure the verticality of the cut and the consistency of the cutting edge.

Double-roller surface winding structure | Easy operation and maintenance

Automatic Roll Slitter adopts a double-roller surface friction winding mechanism with automatic tension adjustment and intelligent pressure roller control functions. Compared with traditional center winding, the structure is more suitable for non-woven materials with uneven thickness or high elasticity, avoiding wrinkling or twisting of materials and improving the neatness of winding.

Specialized trimming and recycling system | Reduce loss

Automatic Roll Slitter integrates film edge trimming and edge material synchronous recycling system, automatically guides the edge material to the recycling box through a high-speed negative pressure conveying pipeline, and the edge cutting is neat, with a material utilization rate of more than 97%, saving costs and reducing the frequency of manual cleaning.

Guangdong Foshan | Daddybaby baby diaper inner material processing

Daddybaby uses the model Automatic Roll Slitter in its Foshan production base to slit hot air non-woven fabrics as the core absorption layer lining material of baby diapers. The wide 2200mm Automatic Roll Slitter supports continuous operation for more than 18 hours a day. The finished product error is less than 0.3mm, the roll is tight, the edges are smooth, and the defective rate is significantly reduced.

Indonesia Jakarta | Softex sanitary napkin adhesive film slitting

Softex installed the model Automatic Roll Slitter in its Jakarta factory for the composite cutting of hot air non-woven fabrics and leakproof bottom films. The metal probe detection system is selected to monitor the possible foreign metal contamination in the material in real time to ensure the safety of the downstream composite process.

Hanoi, Vietnam | Vina Nonwoven Medical Protective Materials Slitting

Vina Nonwoven Company applies Automatic Roll Slitter to the cutting of substrates for medical nonwovens such as protective clothing and isolation gowns. Automatic Roll Slitter supports the slitting of hot air + electrostatic composite nonwovens, equipped with a visual observation light box, so that the operator can observe the slitting status and defects in real time to ensure the cleanliness and functional integrity of the materials.

Istanbul, Turkey | Hayat Kimya Sanitary Products Packaging Film Slitting

Hayat Kimya introduced Automatic Roll Slitter for the final slitting of packaging films and liner materials for sanitary napkins and diapers. Automatic Roll Slitter cooperates with the online defect detection system to automatically mark the location of printing defects, optimize packaging accuracy, reduce manual sorting processes, and improve the efficiency of the entire line by about 21%.

CCD optical system cleaning and calibration

After daily operations, the CCD lens and reflective tape should be gently wiped with a special dust-free cloth and alcohol to prevent dust particles from affecting the recognition accuracy. It is recommended to calibrate the CCD system every 100 hours of operation to check the aging of the light source and the offset of the lens.

Maintenance of the pneumatic structure of the winding system

The pressure roller in the surface winding mechanism is pneumatically controlled. Check the cylinder seal for pressure relief every week to ensure normal operation within the pressure range of 0.45MPa~0.55MPa. If there is a problem of loose or crooked roll, check the air pipe connection and the response time of the solenoid valve.

Periodic calibration of the metal probe detection system

Automatic Roll Slitter is equipped with a metal foreign body probe, which should be tested for sensitivity by professional engineers every month. The size of the tested metal object is Φ0.5mm stainless steel beads, which must be successfully detected and alarmed during the material movement to ensure the cleanliness of the final product.

Circular knife/flat knife wear detection and replacement

After completing 500,000 meters of material cutting, all blades should be checked for wear. If the cutting edge is rough or the curling edge is not neat, the tool should be replaced immediately or the cutting spacing should be adjusted. It is recommended to replace the tool group uniformly every six months to maintain the slitting consistency.

Servo system temperature control and dust prevention

The servo drive cabinet needs to maintain a constant temperature and be clean. Clean the fan filter every 300 hours of operation and check whether the drive temperature is kept within the range of ≤60℃. If abnormal current jumps are found, the control signal and ground interference should be checked.
