Ultra-fine wire continuous electroplating automatic production line
InactiveCN103741186BGuaranteed constant tensionFlat and beautiful wiringFilament handlingProduction lineSurface layer
The invention relates to the technical field of electroplating equipment, and in particular relates to an automatic production line for continuous electroplating of an ultrafine metal wire, which is used for a solution of equipment for electroplating a surface layer of an ultrafine metal wire with other metal plating layers in the electroplating industry. A brand new unwinding mechanism is adopted for performing constant-tension unwinding, so that the tension of the metal wire during the unwinding keeps constant; by virtue of a brand new driving mechanism, the linear speed keeps constant when the metal wire moves in the production line and can be adjusted as required so as to meet requirements of an electroplating process; a winding mechanism can be used for performing constant-torque winding during winding, and the winding torque can be adjusted according to the thickness of the metal wire; by virtue of the brand new winding mechanism, the wire can be accurately arranged according to the winding speed, so that the metal wire can be smoothly and attractively arranged; a buffer mechanism is additionally arranged between the driving mechanism and the winding mechanism, and can be used for balancing the speed difference between the driving mechanism and the winding mechanism.
