Zipper Wire production line II. Structural Features (1) Power Control: The main motor is controlled by a frequency converter for stepless speed regulation, allowing for arbitrary adjustment within the range of 50 to 180 meters per minute. The touch screen displays the current main motor speed. The motors for wire feeding, rolling, flat wire drawing, and wire winding are individually equipped with frequency converters. Through a pneumatic tension rod, the signal of resistance value change is automatically calculated under the control of PLC, instructing the frequency converter to immediately adjust the motor speed, ensuring the tension rod remains stable and adjusting to the optimal tension, maintaining uniform thickness of the outgoing wire diameter. (2) Payoff: Vertical type, active motor drive (3) Rolling mills: Precision rollers synchronously press together. (4) Wire drawing method: vertical Drum,Spray type. (5) Wire take-up method: Axial precision wire take-up (6) Use of special high-quality products: A reduction gearbox sourced from Shanghai Teni. All B bearings (NSK) are either imported or sourced from national first-tier brands (Harbin Bearing Group). 3. Performance Parameters: (1) Wire Entry Range: Wire entry 2.6-6.5MM. (2) Payoff: coils (3) Calendering Range: 250*2+180MM*2 rollers, calendering ratio within 20. (4) Mechanical speed: 180 meters/minute/Max. (Production speed is determined according to different specifications). (5) Finished products: Width 3-12M, thickness 0.8-2.8 MM , Tolerance W/T: (+0.00 & -0.02mm)
