Description

Wire break protection device for twisting machine

technical field

The utility model belongs to the field of twisted wire production tools, in particular to a wire breakage protection device for a twisted wire machine.

Background technique

Twisted wires are widely used. Twisted wires are made of multiple single wires twisted by a twisting machine. There are two commonly used copper and aluminum wires. Copper and aluminum wires can be twisted into various cross-sections of different specifications and different types of wires and cables. Wire core.

The stranding machine is a kind of stranding mechanical equipment that can be widely used in various soft/hard conductor wires. It is a kind of equipment widely used in the wire and cable industry. It twists multiple single conductors into one strand to achieve the process of wire Require. According to the twisting method, the stranding machine can generally be divided into single stranding machine, pair stranding machine, high-speed stranding machine, untwisting machine, cage stranding machine, frame stranding machine, tubular stranding machine and disc stranding machine machine etc.

During the production process of the steel strand on the stranding machine, each strand of steel wire wound on the I-shaped pay-off wheel is tensioned and unwound under the traction of the former through the wire splitter. Because a certain tension is required in the stranding process to ensure that the steel wire The quality of the stranded wire, in the process of traction and unwinding, there will be excessive tension and broken wires or insufficient tension, and the strands will slack. If there is a broken wire and no shutdown is found, the quality of the stranded wire will be affected due to unbalanced force and lack of strands.

The existing steel strand usually needs to be detected by the operator, and then the operator stops the stranding machine for troubleshooting. This method of using human observation will inevitably fail to stop immediately due to temporary negligence, thereby affecting the stranding machine. Quality, and when the thread is suddenly broken, the tight monofilament will swing due to the sudden loss of tension, which will bring safety hazards to the operator.

Therefore need a kind of stranding machine disconnection protection device, can cut off the power supply of stranding machine in time when the stranding machine breaks out phenomenon.

Utility model content

The technical problem to be solved by the utility model is to provide a wire breakage protection device for the stranding machine, so as to solve the fault problem caused by the wire breakage phenomenon in the pulling and unwinding process of the current stranding machine.
