Unreeling frame

Abstract

The invention relates to an unreeling frame which is characterized by comprising a frame body. A soleplate is arranged below two lateral plates of the frame body, a guide wheel bracket is arranged between the two lateral plates above the soleplate which is provided with at least three perpendicular unreeling shafts, a winding rubber shaft is sleeved on each unreeling shaft, a brush gasket is mounted at the upper end of each winding rubber shaft and fixed together with the winding rubber shaft and the soleplate with screws, the brush gasket comprises a backing plate, a plurality of radially distributed elastic brush bristles are symmetrically arranged on the periphery of the backing plate, and guide wheels in the same number as the unreeling shafts are arranged on the guide wheel bracket. The invention has simple and compact structure, convenient use and stable and smooth unreeling, is particularly suitable for unreeling ultrafine enameled wires and keeping the constant tension of the enameled wires between the winding rubber shaft and a wire twisting machine by the elasticity of the elastic brush bristles to avoid breaking the enameled wires, guarantee the qualities of twisted wires, improve the pass rate of products and decrease the production costs of wires.

Description

technical field [0001] The invention relates to cable production equipment, in particular to a pay-off stand used in the process of twisting enameled wires into twisted wires. Background technique [0002] In the wire and cable industry, cables are twisted from thinner enameled wires or twisted into twisted wires from thinner enameled wires and then twisted twice. In the process of twisting the thinner enameled wires into stranded wires, it is necessary to use a pay-off frame, which simultaneously releases multiple enameled wires and twists them into stranded wires by a twisting machine. With the rapid development of household appliances and electronic communication industries, the enameled wire package for making twisted wires is getting thinner and thinner. When the enameled wire is an ultra-fine enameled wire with a wire diameter of 0.03 mm or less, the existing pay-off frame is semi-automatic. Yes, the motor controls the active wire release, but because the motor contro...

Problems solved by technology

With the rapid development of household appliances and electronic communication industries, the enameled wire package for making twisted wires is getting thinner and thinner. When the enameled wire is an ultra-fine enameled wire with a wire diameter of 0.03 mm or less, the existing pay-off frame is semi-automatic. Yes, the motor controls the active wire release, but because the motor control needs to be controlled by the pull of the enameled wire, it is very easy to cause wire breakage during wire release, and it is difficult to ensure the quality of the twisted wire, which reduces the pass rate and causes cable production costs. increase

Previously, the applicant had applied for a patent on an improved pay-off stand, which mainly used a stranding machine to pull the enameled wire, so that the winding rubber shaft rotated on the pay-off shaft to passively pay off the wire. With the reduction of enameled wire on the wire, the pulling force of pulling the winding rubber shaft to passively pay off the wire is getting larger and larger, so that the tension of the enameled wire during twisting changes and affects the quality stability of the twisted wire
