Production system of definite elongation wire

Abstract

The invention discloses a production system of a definite elongation wire. The production system comprises a paying-off machine, a washing machine, an upright installation frame, a dip-coating device, an upright lower-section drying tunnel, an upright upper-section drying tunnel, a cooling roller group and a take-up machine, wherein the washing machine is arranged on the front side of the paying-off machine, the upright installation frame is arranged on the front side of the washing machine; the dip-coating device, the lower-section drying tunnel and the upper-section drying tunnel are sequentially installed on the upright installation frame from bottom to top; the upright installation frame is respectively provided with a wire inlet guide wheel and a wire outlet guide wheel bellow the dip-coating device and above the upper-section drying tunnel, the cooling roller group consists of a roller which is arranged by the side of the top of the upright installation frame and a roller which is arranged by the side of the lower part of the upright installation frame, and the take-up machine is arranged on the front side of the cooling roller group. The production system is more reasonable in structure, and a wire stock is longitudinally elongated in the coating and drying process, so that the thickness of a coating on the surface of the wire stock is more uniform. The quality of the produced definite elongation wire is stable, and the definite elongation effect is better.

Description

technical field [0001] The invention relates to the technical field of wire rod production equipment, in particular to a production system for fixed stretch wires. Background technique [0002] Cutting shrinkage is a common characteristic of plastic materials. When the plastic material is cut, the section retracts, and the ratio of the shortened length to the original length is called the cutting shrinkage. Weatherstrips are usually made of rubber, which has the property of shrinking when cut. In order to reduce the cutting shrinkage rate of the sealing strip and increase the qualified rate of the sealing strip after cutting, in the prior art, a glass fiber filament fixed stretch wire skeleton is usually arranged in the sealing strip to play the role of limiting expansion and contraction (referred to as constant stretch) . [0003] However, the constant stretch effect of the glass fiber yarn is not good enough. In the prior art, there is an urgent need for a new productio...
