Slitting machine operation guide ---
4 operational requirements
4.1 Preparation before cutting:
4.1.1 Before the cutting, the paper sent from the warehouse or the semi-finished products transferred from the previous process should be checked with the “production work order” to see if the paper quality, quantity, specifications, etc. meet the requirements of the work order. If problems such as quantity or quality are found, they should be promptly submitted to the dispatcher or feedback to the squad leader. After confirmation, the logo will be clearly marked and returned to the warehouse or semi-finished product area, and the qualified products will be re-sorted for cutting. If the feedback is not received, it will be deemed as acceptance. If there are quality problems such as insufficient quantity at the end, the personnel will be responsible.
4.1.2 Lubricate the equipment according to the maintenance requirements of the machine and check whether the safety protection devices of the equipment are effective.
4.1.3 Carefully check the quality of the front and back of the paper, graphics, paper, etc., to avoid the material specifications, model or quality of the products that are put into production do not match the requirements of the cut products.
4.2.1 Carefully check the accuracy and sensitivity of the electronic scale and vernier caliper, confirm whether it meets the requirements for use, and report the abnormality in time to report with the squad leader.

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.
