Reasons for the uneven coiling of the slitting line

Uneven coiling caused by insufficient tension: If the tension is weak at the beginning of the coiling, it is prone to misalignment at the end of the coiling. Therefore, the tension is increased at the beginning, and the larger the roll, the smaller the tension. The operation method can effectively prevent the occurrence of misalignment.

Dislocation caused by unbalanced coiling tension: poor straight angle when the coil head is cut, bad straight angle when occluding, incorrect width setting of the uncoiler after the plate is passed, and the steel plate is sent out after the slitting machine is cut and the steel plate is sent out for comparison. The length of the two sides of the steel coil will be different during the big movement. The short side is easy to produce tension changes. Therefore, when winding the steel coil on the expansion and contraction drum of the winder, it is best to confirm that the entire width direction of the steel coil is accurate, and it is tightly attached to the expansion and contraction drum, and then the coiling can be started.

Dislocation caused by poor bite position of the jaws in the expansion and contraction drum of the winder: When the position of the knife, the middle divider, and the bite positions in the jaws of the expansion and contraction drum of the winder are inconsistent, the change of the left and right tension of the steel coil will cause the coiling misalignment.

Coiling dislocation caused by the left and right swing of the steel belt in the looper: The left and right swing of the steel belt in the looper will cause the angle of entering the tension device to change, which will cause the winding dislocation. Use felt and other soft materials to press on the steel belt to prevent the steel belt from swinging.

Coiling misalignment caused by production line stoppage: When the production line is stopped and started, when the tension between the tension device and the winder is reduced, the contact pressure between the steel strips will be reduced, and lateral misalignment is likely to occur, which will cause coiling misalignment. Flexible use of winders and dividers can effectively prevent winding misalignment. 

Rolling misalignment caused by poor divider width setting: The general divider width setting is the width of the finished product plus the thickness of the board. If it is too wide, the steel plate will move left and right, and the coiling will be misaligned.

Slitting machine system signal conversion method

The electro-hydraulic servo control system is adopted in the slitting machine, which mainly uses the conversion between various signals to realize various actions. However, there are many ways of signal conversion, and a detailed understanding helps us to choose.

1. High-speed switching valve method

This method utilizes a high-speed response torque motor to directly or indirectly drive a fixed opening on-off valve. When the digital signal output by the computer is amplified, the front on-off valve can be controlled, so that the valve can control the two states of opening and closing. After the feedback signal is processed by the sampler, it can be transmitted back to the computer in the form of digital quantity to control the work of the slitting machine.

2. Digital-to-analog conversion method

Through the digital-to-analog converter, the digital quantity generated by the computer can be converted into an analog quantity, which is used to control the current acting on the input end of the servo valve or the proportional valve. The feedback signal can also be converted into a digital quantity through an analog-to-digital converter to enter the computer, thereby completing the conversion between the signals.

3. Stepper motor method

It relies on a conversion method realized by the stepper motor controller, which inputs the digital signal output by the computer into the converter in a pulse mode. The rotation angle of the stepping motor is converted into the opening of the valve through a set of transmission device, thus forming a digital flow valve. In addition, its outlet pressure is proportional to it to form a digital pressure valve, thus achieving the goal.
