Equipment for synchronously producing multiple fiber insulating sleeves with ultraviolet light curing technology

Abstract

The invention discloses equipment for synchronously producing multiple glass fiber insulating sleeves with an ultraviolet light curing technology, which comprises a blank pipe guide device, a coating device, a light source system, a sleeve traction device and a resin mixing and preheating kettle, wherein the blank pipe guide device is positioned at the foremost end, and the coating device is positioned at the rear of the blank pipe guide device; the light source system is positioned above the coating device, and the sleeve traction device is positioned at the rearmost end; and the resin mixing and preheating kettle is positioned at the inclined top of the coating device and is communicated with the coating device through a feed pipe. The light source system comprises a hood, a central fluorescent tube and reflectors, and the central fluorescent tube can generate ultraviolet light. The hood forms a closed box shape, and the central fluorescent tube and the reflectors are arranged in the hood. The number of the reflectors is at least two, and the reflectors are uniformly distributed in the same plane. The cross section of each reflector is semielliptical, and one focal point of all reflectors is superposed. The central fluorescent tube is positioned at the superposed focal point. According to the equipment, the utilization ratio of light sources and energy sources is increased.

Description

technical field [0001] The invention relates to the technical field of devices for producing fiber insulating sleeves, in particular to a device for synchronously producing multiple fiber insulating sleeves using ultraviolet light curing technology. Background technique [0002] At present, domestic fiberglass bushings are generally produced by heating and baking solvent-based insulating varnishes. The disadvantages are "two highs and one low", namely high energy consumption, high pollution and low efficiency. The use of ultraviolet light curing technology and solvent-free light curing formula can solve the above problems very well, and has the advantages of "two lows and one high" such as low energy consumption, low pollution, and high efficiency. Patent CN 101665656A discloses a formula and preparation process of UV-curable insulating varnish for the production of glass fiber insulating sleeves, but it needs to complete the feeding of the tubular glass fiber, coating of th...

AI Technical Summary

Problems solved by technology

Applied to glass fiber insulating hoses Due to the requirements of mechanical properties and insulation properties, there are strict requirements on the molecular weight of the light-curing main resin, the amount of active diluent, and the thickness of the coating film (about 100 μm). Using optical fiber light curing The equipment cannot meet the requirements of glass fiber insulating hose for paint film thickness and mechanical properties

In addition, foreign countries with advanced technology have light curing equipment for complex three-dimensional configurations such as automobiles and wooden furniture. However, it is not cost-effective to apply it to ultraviolet light curing products of tubular materials such as glass fiber sleeves and enameled wires. Conducive to the improvement of efficiency

A light-curing system and method suitable for continuous production of light-cured fiberglass hose insulation sleeves, including surface coating and curing of multiple pipes, is the first to be proposed, and it is used in the production of fiber insulation sleeves by light-curing technology The equipment has not been produced or reported by relevant manufacturers
