Paying-off mechanism of metal wire weaving machine

Abstract

The invention discloses a paying-off mechanism of a metal wire weaving machine. The paying-off mechanism comprises a paying-off rack, wherein a plurality of paying-off devices and tension control devices are arranged on the paying-off rack; each paying-off device comprises a variable-frequency motor, a transmission shaft used for fixing a wire wheel, and a wire separating roller; the variable-frequency motor drives the wire wheel fixed to the transmission shaft to rotate; metal wires pass through the wire separating roller and are output; each tension control device comprises a fixing frame, a rotating wheel, a linear guide rail, a tension wheel and a displacement sensor; the rotating wheel is fixed at the upper end of the fixing frame; the linear guide rail is vertically arranged on the fixing frame; the tension wheel can move up and down along the linear guide rail; the metal wires output through the wire separating roller are downward after passing through the rotating wheel, then are upward after passing through the tension wheel, and are output after passing through the rotating wheel finally; when the displacement of the tension wheel changes, the displacement sensor detects the displacement change of the tension wheel and outputs an electric signal; and the displacement sensor is connected with the variable-frequency motor through a control circuit. The paying-off mechanism of the metal wire weaving machine has a simple structure, and can ensure that the speed and the tension of the metal wires which are output finally are the same.

Description

technical field [0001] The invention relates to equipment used in the braiding process of metal wires, in particular to a pay-off mechanism for braiding metal wires. Background technique [0002] The metal wire braiding machine includes a pay-off mechanism, a joint mechanism and a winding mechanism. The function of the pay-off mechanism is to output multiple metal wires to the joint mechanism. The joint mechanism combines the metal wires with the same tension together, so the multiple metal wires Before sending to the plying mechanism, it is necessary to ensure that the tension of each output metal wire is the same. The pay-off mechanism includes a motor and a reel, and the metal wire wound on the reel is output under the rotation of the motor. Due to the speed of the motor and the weight change of the reel during the pay-off process, the output speed and tension of each wire vary. Different, so the metal wire behind the wire wheel needs to adjust the tension of the metal...
