Sensitive brake mechanism

Abstract

The invention belongs to the technical field of tools, and particularly relates to a sensitive brake mechanism. The sensitive brake mechanism which comprises a machine frame, a traction frame is hinged to the middle of a driven roller and a lead frame on the rear side of the machine frame, the traction frame comprises a traction rod and a connecting rod, and the wire outgoing of a coil is prevented; the action of the traction rod is that when the tension of the wire outgoing is controlled by utilizing the factors of the weight of the traction rod, the traction rod can be lifted upwards, so that a brake pad is separated from a friction wheel, and the coil to rotate; when the tension disappears, the traction rod moves downwards, so that the brake pad makes contact with the friction wheel tobrake the coil. The sensitive brake mechanism has the beneficial effects that the coil can be braked in time when the pulling wire is stopped, a certain wire end reserved amount is provided for the next pulling wire, so that a cable is prevented from being in a tensioned state in the pulling wire process.

Description

technical field [0001] The invention belongs to the technical field of appliances, in particular to a sensitive braking mechanism. Background technique [0002] When the current cable is processed, the raw material cable needs to be pulled out of the coil. The current common practice of enterprises is to set a support, set a roller on the support, and then set the coil on the roller, and then directly pull the wire out and put it into the processing mechanism. When the cable is being processed, it is often not continuously pulling the wire. Instead, after a part of the wire is pulled out, the wire pulling action stops, and this part of the wire is pulled out for processing. This type of operation makes the current outlet mechanism have a defect: due to the action of pulling the wire, the coil will be rotated under the action of pulling force to exit the wire. But when the pulling action stops, the pulling force on the coil disappears, but the coil will still rotate out of ...

AI Technical Summary

Problems solved by technology

This kind of operation makes the current outlet mechanism have defects: due to the action of pulling the wire, the coil will be rotated under the action of tension to exit the wire

When the pulling force disappears, the coil still rotates out of the wire, so that the wires coming out of the coil cannot be pulled away in time, and the wires will pile up together, so that the wires are interlaced and even knotted with each other, affecting the next time the wires go out, thus affecting the entire processing
