AI Technical Summary
当前,丝材涂层处理一般都采用浸涂方式,其主要存在三大技术瓶颈:一是涂层完整性缺陷,传统浸泡工艺存在“边缘效应”,丝材盘卷重叠部位涂层覆盖率低,影响润滑效果;二是烘干过程中在重力影响下,涂层物质发生迁移,导致层厚不均匀;三是生产效率低,浸涂工艺一般把涂覆和干燥进行分步处理,导致生产周期较长,每批次处理时间可达5-6小时,与此同时,转运过程会造成3-5%的丝材表面擦伤,对于稀贵金属而言,这样的处理方式会直接大幅增加生产成本
1、利用皂化液浸涂而不是喷雾涂覆,在保证丝材的涂覆更加充分和均匀的前提下,增加了皂化液的利用率。

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of metal material processing technology, and more specifically, this utility model relates to an integrated coating device. Background Technology
[0002] During the drawing process of metal wires, a coating is typically applied to improve surface smoothness and wear resistance, and reduce damage to the wire. This coating provides a lubricating effect, and its thickness and uniformity directly affect the quality of the wire. Currently, wire coating is generally done using dip coating, which has three main technical bottlenecks: First, coating integrity is compromised. Traditional dip coating processes suffer from an "edge effect," resulting in low coating coverage at overlapping areas of the coiled wire, affecting lubrication. Second, during the drying process, the coating material migrates under gravity, leading to uneven layer thickness. Third, production efficiency is low. Dip coating typically involves separate coating and drying processes, resulting in a long production cycle, with each batch taking 5-6 hours. Furthermore, the transfer process causes 3-5% surface abrasion on the wire. For rare and precious metals, this method significantly increases production costs.
[0003] To address the problems with existing solutions, some in the industry have proposed a spray coating method (also known as "spraying"), which involves atomizing the coating material and applying it evenly to the surface of the wire. While spraying is highly efficient and provides a more comprehensive and thorough coating, it suffers from "atomization loss" for wires with a diameter less than 3.0 mm, as the utilization rate of the saponification liquid is less than 60%. In addition, electromagnetic levitation drying technology can be used to address the wear and tear on the wire during transport, but its equipment cost is too high, around 2 million yuan per unit, making it unsuitable for preparing rare and precious metal wires like hafnium, which are highly sensitive to production costs. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides an integrated coating device.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An integrated coating device includes a coating section and a drying section. The coating section includes a saponification liquid box, an electric heating rod, and rollers. The electric heating rod is located at the bottom of the saponification liquid box and arranged in a U-shape. An installation rod is provided at the top of the saponification liquid box, and the rollers are mounted on the installation rod and can slide on the installation rod. The drying section includes a drying barrel and infrared heating tubes. The infrared heating tubes are evenly arranged on the inner side wall of the drying barrel.
[0006] This utility model discloses an integrated coating device, wherein the saponification liquid box and the electric heating rod are both made of stainless steel.
[0007] This utility model discloses an integrated coating device, wherein the roller is made of ceramic material.
[0008] This utility model discloses an integrated coating device, wherein the drying barrel is wrapped with an alumina fiber insulation blanket.
[0009] This utility model discloses an integrated coating device, wherein the roughness Ra of the roller is ≤0.2μm.
[0010] This utility model discloses an integrated coating device with a temperature accuracy of ±0.5°.
[0011] Compared with the prior art, the present invention has the following advantages: 1. Using saponified liquid for dip coating instead of spray coating increases the utilization rate of saponified liquid while ensuring more thorough and uniform coating of the filament.
[0012] 2. Drying and coating are connected workstations, which avoids damage to the filaments during the transfer process and shortens the production cycle.
[0013] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0015] An integrated coating device includes a coating section and a drying section. The coating section includes a saponification liquid box 4, an electric heating rod 3, and rollers 2. The electric heating rod 3 is located at the bottom of the saponification liquid box 4 and arranged in a U-shape. A mounting rod is provided at the top of the saponification liquid box 4, and the rollers 3 are mounted on the mounting rod and can slide on the mounting rod. The drying section includes a drying barrel 6 and infrared heating tubes 5, which are evenly arranged on the inner side wall of the drying barrel 6. The saponification liquid box 4 and the electric heating rod 3 are both made of stainless steel. The rollers 2 are made of ceramic. The drying barrel 6 is wrapped with an alumina fiber insulation blanket. The roughness Ra of the rollers is ≤0.2μm. The temperature accuracy of the coating device is ±0.5°.
[0016] Working principle and method The saponification liquid is continuously heated by the bottom electric heating rod 3 to keep it in a liquid state. When the wire enters the saponification liquid box 4, the whole process is kept at a constant speed. The wire is guided in multiple directions by the internal ceramic rollers 2 so that the surface of the wire is completely covered with saponification liquid. Then, the saponification liquid film is solidified by air cooling. After that, it enters the infrared heating tube 5 for heating and drying. It is kept warm in the drying barrel 6 to remove excess moisture from the surface film. After air cooling for a period of time, it can be directly molded and drawn.
