本文介绍原有验毡机与改造后的验毡机控制方式的比较，着重介绍改造后的验毡

This article introduces the comparison between the original felt inspection machine and the modified felt inspection machine control method, focusing on introducing the modified felt inspection machine control principle to achieve the functions already achieved, the system control is mainly completed by the PLC, by reading the touch screen set operation Data to control the running linear speed and tension of the system. The system will control the torque of the unwinding magnetic powder according to the unwinding diameter set by the operator. As the diameter of the unwinding becomes smaller, the system will maintain a constant tension unwinding.

This paper introduces the comparison of the original felt machine and the control mode of the after-reform felt machine, and focuses on the control principle of the transformed felt machine to achieve both the function, the system control is mainly completed by the PLC, by reading the operating data set by the touch screen, the operating line speed and tension of the system is controlled. The system will control the torque of the roll-up magnetic powder according to the roll diameter set by the operator, and maintain the constant tension of the system as the roll diameter becomes smaller.

This paper introduces the comparison between the control mode of the original felt inspection machine and the reformed felt inspection machine. It focuses on the control principle of the reformed felt inspection machine to realize the realized functions. The system control is mainly completed by PLC. By reading the operation data set on the touch screen, the system's operation line speed and tension are controlled. The system will control the torque of the unwinding magnetic powder according to the unwinding diameter set by the operator, and keep the constant tension of the system unwinding with the decrease of the unwinding diameter.<br>
