Reasons, countermeasures and effects of BOPP film slitting quality ---
two. Wrinkles (wrinkles, vertical wrinkles, cross wrinkles, wrinkles)
With the continuous improvement of slitting technology, the length of wrinkle is becoming less and less, and the products of individual manufacturers have achieved zero wrinkle, which undoubtedly grasps the opportunities in the fierce competition environment. It is worth noting that the wrinkles that we sometimes appear are not caused by the unreasonable setting of the cutting parameters, but because our operators are not responsible for the work, and the film is not attached to the paper tube but is free. After the film is put on the paper tube, it is turned on and cut, and the quality of the wrinkle is artificially created. It must be paid attention to, eliminate the defects of human quality and improve the quality of the product.

Slitting machine parts ---
1. Type of inspection system for the tension and speed of the slitting machine:
1 Tension sensor detection: The tension sensor is installed under the bearing of the tension detecting roller, converts the detected aluminum foil tension into an electrical signal, sends it to the tension adjuster, compares it with the original set tension signal, performs PID calculation, and then inputs The winding motor controller achieves the purpose of controlling the tension and rotation speed of the winding roller.
2Floating roller indirect tension detecting system: a set of floating roller is installed in front of the aluminum foil tracking roller. The position of the floating roller is detected by a potentiometer. The tension control method is to keep the tension constant by keeping the position of the floating roller as constant as possible. .
3 The magnetic powder clutch is used to control the rotational torque of the input winding roller to achieve tension control: the magnetic powder clutch is composed of an active part and a driven part, and is connected to the winding roller through a transmission mechanism such as a universal joint, and the fine ferromagnetic powder is filled in the middle. As a torque transmission medium. A magnetic field is formed by applying a constant current to the exciting coil, and the magnetic powder is magnetized. The magnetized magnetic powder attracts each other to form a chain arrangement. When the active part rotates at a constant speed, the coupling force between the magnetic powders is broken to form a circumferential tangential force, and the product of the tangential force and the radius of the magnetic ring is the driving driven part. The winding torque of the winding realizes the coupling of the output torque from the active part to the driven part in continuous rotation, thereby achieving the purpose of controlling the tension.
4 slitting Unwinding capacity and speed detection system: The magnetic powder tension brake is mainly used to control the unwinding force and speed. The working principle is: the coupling is installed in the magnetic powder brake, and the input parts and output with magnetic coils are installed. component. Below the magnetic coil is an annular groove, the underside of which is an annular rotor or output member. The annular groove is located at the center of the output member and is filled with magnetic powder. When there is excitation current in the magnetic coil, the coil generates magnetic flux to align the magnetic powder in the direction of the magnetic field, thus generating damping between the input member and the output member, and transmitting the torque. If the tension and speed applied to the aluminum foil are increased or decreased, the magnitude of the exciting current can be changed, or the magnitude of the current applied to the coupling coil by the varying amplifier can be effectively controlled.
