| 3 | Rubber extruder is a basic equipment in the rubber industry. Rubber product extrusion is a process of continuous molding through a certain shape of die under the pressure of the rubber extruder screw. Rubber extruder is mainly used to manufacture various semi-finished products such as treads, inner tubes, and tapes. It is one of the key equipment that affects product quality and plays a very important role in the production process of tires and rubber products. | ||

| 9 | After the rubber enters the feeding port, it forms a rubber mass of a certain size under the pushing action of the rotating screw. Then the rubber mass sent from the feeding section is compacted, further softened, and the air entrained in the rubber is removed. Then the rubber delivered from the compression section is further stirred. At this time, the rubber in the thread groove has formed a completely fluid state. The rotation of the screw promotes the rubber to flow and is extruded from the die head with a certain capacity and pressure. When the rubber is extruded, the receiving device works synchronously. VC is used for the receiving process of rubber, completing the traction action | ||

| 12 | |||
| 13 | Use an external tension sensor (0-10V) to perform PID adjustment to keep the receiving speed consistent with the extrusion speed. | ||
| 14 | |||
| 15 | Use an external button to control the start and stop of the VFD, requiring high speed stabilization accuracy and fast response speed. | ||

| 46 | * VC VFD provides a standard 0-10V analog interface, which is compatible with tension sensors, has strong versatility and strong anti-interference ability. | ||
| 47 | * The system uses a tension sensor (rocker), which works with the PID function of the VC to respond quickly. The rubber receiving speed is consistent with the extrusion speed, avoiding the problem of rubber being too loose or too tight. | ||
| 48 | * All-round protection function: VC VFD has overload, overcurrent, overvoltage and undervoltage protection functions, which can effectively ensure the normal operation of the entire system |
