There will be some problems in the use of slitting line machine, and how to overcome these problems is crucial.
The servo system feeding of Slitting line machine system is completed by a set of servo, which is an open-loop system. The servo motor takes as many positions as the upper computer sends out pulses, and there is no monitoring for mechanical clearance and steel plate skidding. In the solution, a speed measuring device is installed on the steel plate after feeding, and the actual feeding speed of the steel plate is fed back to the servo driver as PID feedback from time to time. The PID given is determined by the pulse rate of the upper computer. If the PID given is equal to the feedback, the steel plate does not slip, so compensation is made. When the two are not equal, there will be slipping. The servo driver uses the built-in dynamic compensation function to dynamically supply the feeding error system from time to time. This scheme can be so simple and reliable, mainly because VEC servo has built-in dynamic compensation function, which can compensate from time to time and achieve better goals. There are also schemes to solve the accuracy problem by using PLC secondary feeding after the encoder detects the slipping length, but the scheme of PLC pulse secondary feeding reduces the working efficiency of the equipment.
Before using the Slitting line machine, we must do a good job of inspection. First, check the installation integrity of the bottom line, and determine whether their contact is in good condition. Equipped with appropriate power supply according to the specified rated parameters, and at the same time, determine the stability of the power supply to ensure that there will be no poor contact. Secondly, try to use the original accessories produced by the manufacturer, try not to refit the leveling machine, and at the same time wipe the appearance and seal of the machine regularly, so as to achieve the state of no corrosion and no oil stain as much as possible. At the same time, clean the work roller and idler to ensure that there is no crack before it can work normally. If it is found that the leveling machine smokes or makes abnormal noise at work, it is necessary to immediately close the leveling machine and stop working, otherwise there may be a fire, so the power supply must be turned off. According to the requirements of the maintenance and maintenance of the Slitting line machine, so as to prolong the service life of the slitting line machine. It is often the various parts of the slitting line machine to ensure the cleanliness of the leveling machine, so as to make the slitting line machine work better.
