Description

A cable pay-off machine for brake power generation

technical field

The utility model relates to a pay-off machine, in particular to a cable pay-off machine for braking power generation.

Background technique

Pay-off machines can generally be divided into active back-twist pay-off machines, vertical power pay-off machines, dual-axis power pay-off machines, dual-axis multi-head drawing disc active pay-off machines, and shaftless pay-off machines. Twisting pay-off machine, mainly equipped with twisting machine for unwinding, plays a role of pre-twisting, and can realize twisting with bundles to meet customer requirements for twisted wires with small cross-sectional area; double-axis power pay-off machine, mainly used for two core wires Pay-off when twisting; dual-axis multi-head drawing disc active pay-off machine, suitable for multi-strand conductor pay-off, equipped with stranding machine and wire doubling machine for pay-off; shaftless pay-off machine, suitable for extruder It is used for reeling out cables. When the existing pay-off machine is braked, the friction brake system is generally used for braking; the traditional friction brake system will not only cause noise pollution, but also the brake parts will continue to wear during the working process, and the braking performance will continue to decline. If it is not replaced in time, it may lead to a safety accident and cause huge losses to people's lives and property. Frequent replacement of brake components will increase maintenance costs and cause a greater economic burden.
