Abstract
The invention is a dynamic tension regulating method of screening wire winder and its structure, relating to a special machine for producing electric wire, especially producing machinery for producing the screening wire of external interference signals. Its technical project as follows: dynamically regulating the change of electromagnetic force to make electromagnet on a tension device move with the tension device. Its structural project as follows: a magnetic powder brake is fixed on a core wire disc, and electromagnetic coil is fixed on a machine frame on one side of the magnetic powder brake and connected with PLC. Its structure is simple, and it can change the tension by the change of wire quantity in the core wire disc, sets a change value in the PLC, and dynamically regulates the size of tension in a state without stopping the winder to assure the winding quality and tightness of the screening wire.
Description
Technical field:
The present invention relates to a kind of special purpose machinery of the electrician's of production wire rod, refer in particular to a kind of manufacturing machine of producing the shielding conductor of shielding external interference signal.
Background technology:
Shielding conductor is the electric wire that is twining one deck copper cash at the skin of inner core electric wire tightly.When the signal of telecommunication when internal core wire transmits, because of being subjected to the shielding action of outsourcing copper cash, and be not vulnerable to the interference of external electromagnetic field, reach the clear wash rice of the signal of telecommunication of transmission and distortionless purpose.It is applied to many necks cities such as military affairs, industrial or agricultural, people's life, and day by day is widely used.And as the shielded wire winding machine of producing shielding conductor, its production efficiency but lags behind other technical machinery out and away.I had once proposed how to solve high rotating speed of shielded wire winding machine and the concrete scheme of vibrating this a pair of contradiction in 98113210.3 and 00117515.7 patent of invention, make the rotating speed of shielded wire winding machine be improved, and production efficiency improves greatly.So, we find in process of production, although the rotation of tensioner is with coaxial to the rotation of coil holder and core line disk, but the tension force of tensioner can only be regulated under the state of static state, that is to say, before wrapping machine does not rotate as yet, the elasticity that the operator reaches the standard grade according to core line disk, give the factors such as rotary speed of coil holder, thereby preestablish a constant tensile force, hardly realize, line on the core line disk is in dynamic change, minimizing gradually as the core line disk overall weight, the coil diameter that is wrapped on the core line disk diminishes, line moving up and down on core line disk etc., all directly have influence on the variation of tension force, and because the tension force of tensioner is constant, and then directly have influence on the quality of shielding conductor.
Summary of the invention:
The objective of the invention is to overcome above-mentioned weak point of the prior art, and a kind of method and structure thereof of shielded wire winding machine dynamic adjustments tension force are provided.
Method of the present invention is achieved by the following technical solution: the dynamic adjustments change of electromagnetic force makes electromagnet and tension force servo-actuated on the tensioner;
Structure of the present invention is achieved by the following technical solution: magnetic powder brake is fixed on the core line disk, and solenoid is packed on the frame of a side of magnetic powder brake, and solenoid is connected with PLC.
The present invention is simple in structure, can cause the variation of tension force to preestablish the numerical value of variation according to the variation of core line disk center line amount in PLC, and under the state that does not need to shut down the size of follow-up adjustment tensioner, guarantee the winding mass and the elasticity of shielding conductor.
Description of drawings:
Accompanying drawing is a structural representation of the present invention
Embodiment:
Method of the present invention is achieved by the following technical solution: the dynamic adjustments change of electromagnetic force makes electromagnet and tension force servo-actuated on the tensioner;
Structure of the present invention is achieved by the following technical solution: see accompanying drawing, magnetic powder brake 4 is fixed on the core line disk 3, and solenoid 5 is packed on the frame 1 of a side of magnetic powder brake 4, and solenoid 5 is connected with PLC.
Because the heart yearn 6 on the core line disk 3 is in winding process, requirement has suitable tension force to the heart yearn that is wound, because of than, when extraneous electric current passes to copper ring 52 by brush 51, again by copper ring 52 to magnetic powder brake 4 input voltages, because voltage is in the pay off rack rotation process, by the PLC automatic control and adjustment in the peripheral control unit, variation along with controllable voltage, make magnetic powder brake 4 produce different drag, and magnetic powder brake 4 to be connected with core line disk 3 be an integral body, this just makes and produces a rotary speed that changes and lag behind with the core line disk 3 of giving coil holder 2 coaxial rotations that the also just feasible heart yearn 6 that is wound has suitable tension force.
