Description

External tensioning wire tensioning device of steel cord stranding machine {APPARATUS FOR MAINTAINING CONSTANT TENSION OF EXTERNALLY PROVIDED WIRE OF STEEL CORD TYPE STRANDER}

The present invention relates to a scheduler capable of constantly adjusting the braking force of a steel cord twister using an external supply line tension scheduler, and more particularly, to provide a braking device in a steel cord strander to adjust the braking force. The present invention relates to a tensioning device for external supply wire tensioning of a steel cord twisted pair that maintains a constant tension of external wire drawn out from an external wire supply bobbin to contribute to quality stabilization.

Generally, stranded wire for steel cord manufacturing, which is usually used as a reinforcement material for rubber products such as automobile tires and industrial belts, is a stranded wire that is manufactured so that only a specific structure can be used professionally within the range that steel cords having various structures can be produced. The transition is being made, and there is a growing need to develop steel cord stranders that can produce high quality wire products.

Conventionally, a twisted pair for manufacturing a steel cord as a vehicle tire reinforcement is divided into an external wire supply unit 10 for supplying external wires and an internal wire supply unit 20 for supplying internal wires, as shown in FIG. Winding the winding section 40 and the drawn cord with a predetermined tension to draw the cord twisted to the outside of the twisted portion 30 that twists the external wire and the internal wire supplied from the supply unit 10 and the internal wire supply unit 20 The external element wire supply unit 10 is a braking means for controlling the tension of the element wire 1 released from the second bobbin 12 in the first bobbin 11 on which the element wire 1 is wound. It consists of.

When large bobbins are used in the stranded structure, the moment of inertia is severely changed by the weight difference of the bobbin wound on the bobbins, so that different braking force should be applied at full winding and empty winding. At this time, in the case of full bobbin, the moment of inertia increases, so the braking force is increased for tension adjustment, and the moment of inertia due to weight reduction of the bobbin decreases toward the bobbin, so the braking force should be gradually reduced.

Therefore, due to the above-mentioned reason, the conventional steel cord twisted pair always controls the rotation of the bobbin with only a constant braking force, so it is difficult to apply a braking device to a large bobbin, so that it is difficult to maintain a constant tension and contribute to quality stabilization. In addition, when the operator manually adjusts the bobbin tension of the steel cord twisted pair, there is a problem that a defect such as disconnection may occur due to a misoperation or immaturity of the operator.

Therefore, the present invention has been made to solve the conventional problems as described above, the object of the present invention is to install the various braking device in the steel cord twisted pair can adjust the braking force of the twisted pair is drawn out from the external wire supply bobbin An object of the present invention is to provide a tensioning device for external supply wire tensioning of a steel cord twisted pair to maintain a constant tension of an external wire.
