Eccentric winding mechanism of glass fiber covered wires

Abstract

The invention relates to an eccentric winding mechanism of glass fiber covered wires, which comprises a hollow shaft, an adjusting tension handwheel, an adjusting tension conical disc, tension levers, a planetary disc, a yarn-showing ring, a yarn-showing disc, a yarn-showing wire-drawing rod, friction blocks and a friction roller. The adjusting tension handwheel and the hollow shaft are in homocentric threaded connection; the adjusting tension conical disc is homocentrically arranged at the front end of the adjusting tension handwheel and connected with the hollow shaft by a bearing for matching rotation; the planetary disc is homocentrically arranged at the front end of the adjusting tension conical disc and fixedly connected with the hollow shaft by a screw; the yarn-showing disc is homocentrically arranged at the front end of the planetary disc and fixedly connected with the planetary disc by a screw; the yarn-showing ring is homocentrically arranged between the yarn-showing disc and the planetary disc and fixed on the planetary disc by adopting a screw; the middle parts of the tension levers are alternately, evenly and fixedly connected with the planetary disc by screws; one end of each tension lever is provided with a friction block; and the tension of a fiberglass yarn group is adjusted by force which is applied to the friction roller connected with the planetary disc by the friction block. The invention has reasonable design and remarkable effect.

Description

technical field [0001] The invention relates to a production equipment for special cables, in particular to an eccentric wrapping mechanism for glass silk covered wires. Background technique [0002] At present, in the field of glass fiber covered wire production, concentric wrapping mechanisms are generally used. The disadvantages of concentric wrapping are: (1) low output; the line speed of concentric wrapping is generally 2-3 m / Minutes, and the number of revolutions of the wrapping mechanism exceeds 500RPM, the vibration of the wrapping mechanism will cause the wire to vibrate and affect the product quality. (2) The bending resistance of the wire is poor; because the pitch of the concentric wrapping is small, the tensile force in the length direction of the glass fiber insulation wire is small, which affects the bending resistance of the glass fiber covered wire. [0003] In a word, the current concentric wrapping mechanism for glass fiber-wrapped wire has the disadvant...

Problems solved by technology

[0002] At present, in the field of glass fiber covered wire production, concentric wrapping mechanisms are generally used. The disadvantages of concentric wrapping are: (1) low output; the line speed of concentric wrapping is generally 2-3 m / Minutes, and the number of revolutions of the wrapping mechanism exceeds 500RPM, the vibration of the wrapping mechanism will cause the wire to shake and affect the product quality

(2) The bending resistance of the wire is poor; because the pitch of the concentric wrapping is small, the tensile force in the length direction of the glass wire insulation wire is small, which affects the bending resistance of the glass wire covered wire

[0003] In short, the current concentric wrapping mechanism of glass fiber covered wire has the disadvantages of low product output and poor product quality.
