Tire pad rubber cutting control method based on PLC

The invention discloses a tire pad rubber cutting control method based on a PLC. In the tire pad rubber cutting control method based on the PLC, positions and speeds of a high-speed feeding section, alow-speed feeding section and a medium-speed feeding section of a servo motor can be set through a human-computer interface connected with the external PLC, the human-computer interface can be additionally arranged, then servo alarm can be displayed on the human-computer interface in each step, so that it is guaranteed that the whole cutting process is visual and controllable; the servo motor canbe replaced with a variable-frequency motor, so that the purpose of reducing the cost is achieved; and a detection device in the method has the advantages that the structure is reasonable and simple,the production cost is low, the installation is convenient, the function is complete, through a cleaning air hole provided in the method, high-pressure gas in a gas source pipe can be uniformly blownto the surface of a product
