Real-time length measuring device for spiral welded pipe cutting self-adaptation

The utility model provides a self-adaptive real-time length measuring device for spiral welded pipe cutting. According to the device, five photoelectric sensors are arranged on a steel pipe productionline respectively, the initial position of a cutting trolley is arranged at the position 8 meters away from the fifth photoelectric sensor, the five photoelectric sensors are connected with a DI module in a logic programmable logic controller (PLC) through signal cables respectively, a forming machine is arranged at one end of the steel pipe production line, and a delivery machine is arranged onone side of the forming machine. A delivery roller in the delivery machine is provided with a rotary pulse encoder, and the rotary pulse encoder is connected with a pulse receiving module in a logic programmable logic controller (PLC) through a signal cable. The device adaptively measures the real-time length of the outlet pipe of the pipe cutting station of the spiral pipe main machine, and doesnot need to manually adjust
