Transmission device suitable for stable take-up and pay-off of spool

Abstract

The invention discloses a transmission device suitable for stable take-up and pay-off of a spool, and belongs to the technical field of take-up and pay-off of steel wires of metal products for deep processing of wire rods and wire rods. The transmission device comprises a force transmission shaft driven by a force application device, a telescopic shaft arranged at the output end of the force transmission shaft in a sleeving mode, a magnetic power disc fixed to the output end of the telescopic shaft, a soft magnetic core embedded in the magnetic power disc, a spool rotating disc installed at the input end of a spool shaft, and the spool arranged at the output end of the spool shaft in a sleeving mode. A conductive brush is embedded in the telescopic shaft in the radial direction, one end ofthe conductive brush is communicated with the soft magnetic core, and the other end of the conductive brush is externally connected with a magnetic regulator through a wire. The magnetic power disc and the spool rotating disc are automatically attracted through the electromagnetic effect to achieve flexible connection and synchronous rotation, power or resistance can be stably transmitted to thespool, the steel wires are in the consistent tightness and constant-speed running state all the time, and the transmission device has the advantages of being stable in transmission, safe to use, highin work efficiency, clean, free of pollution, easy to operate and capable of saving time and labor.

Description

technical field [0001] The invention belongs to the technical field of wire and wire rod deep processing metal product steel wire take-up and pay-off, and more specifically relates to a transmission device suitable for smooth take-up and pay-off of an I-shaped wheel. Background technique [0002] During the drawing process, the steel wire has to go through drawing, rolling and heat treatment processes. In the handover process of the above processes, the I-shaped wheel is required: that is, the I-shaped wheel is used to actively take up the wire at the end of the previous process, and the turnaround is transferred to In the next process, the I-shaped wheel is used to passively pay off the wire. Utilizing the I-shaped wheel to take up the wire actively or passively pay off the wire all need to transmit power or resistance to the I-shaped wheel. Due to the self-weight of the I-shaped wheel and the weight of the steel wire, the I-shaped wheel needs to be rotated stably and at c...

Problems solved by technology

However, in the current existing power transmission devices, mechanical connection structures are often used between the rotating disc of the I-shaped wheel and the power transmission shaft (that is, the power shaft or the resistance shaft), such as mechanical connection transmissions such as pins, shift levers, chains or gears. On the one hand, after working for a long time, it is prone to unstable running tension and uneven winding tension; on the other hand, the sharp teeth of the gear are easy to hurt people, causing potential safety hazards; It will cause site pollution, and the greasy floor of the production workshop will easily cause operators to slip and fall
