s7, then the tension sensor (71) senses the tension of the molybdenum wire (5) after threading, when the molybdenum wire (5) is too loose, the tension sensor (71) transmits a signal to the microcontroller (73), the microcontroller (73) controls the stroke distance of the stroke cylinder (72) according to the signal data, then the stroke cylinder (72) drives the two limit slide bars (75) to synchronously move downwards through the fixing plate (74), the two limit slide bars (75) drive the connecting plate (77) to move downwards, the connecting plate (77) drives the tension wheel (79) to move downwards in the vertical through groove through the rotating rod (78), and the tension wheel (79) is tightly attached to the molybdenum wire (5), meanwhile, the rotating rod (78) drives the T-shaped sliding block (19) to slide in the T-shaped sliding groove (18) in an auxiliary mode, and due to the characteristic that the molybdenum wire (5) is easy to break, the limit spring (76) can elastically limit the tension wheel (79) through the limit slide bars (75), the tension of the molybdenum wire (5) is accurately adjusted by the tension wheel (79);
s8, after the tension of the molybdenum wire (5) is adjusted, the electric telescopic rod (24) drives the upper pinch roller (25) to downwards compress and limit the molybdenum wire (5) through the limit transmission fit of the lower pinch roller (26), so that the molybdenum wire (5) can be normally cut and used.
