Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of insulation treatment in metal wire processing, in particular, relates to a continuous production line for enameled wire. BACKGROUND

[0002] At present, in the process of metal wire processing, some fields need to use metal wires with external insulation for electrical connection, and then need to coat paint on the outer surface of the metal wire, and then dry the paint to make it firmly adhere to the metal wire, so as to improve the insulation performance of the outer surface of the metal wire. In the process of processing, the paint is generally applied on the surface of the metal wire by coating roller or spray head, so that the whole processing procedure is continuous. However, since the coating roller or spray head is used to apply the paint, it cannot ensure that the paint can fully cover the surface of the metal wire, and it is easy to miss locally, thereby reducing the insulation and quality of the metal wire. Moreover, after the paint is coated, when the paint is dried by using drying equipment, in order to ensure the drying effect, the drying time and / or the effective drying length of the drying equipment need to be increased, thereby making the space occupied by the whole drying equipment larger, the energy consumption of the drying equipment higher, and the drying efficiency lower.

DETAILED DESCRIPTION

[0036] The preferred embodiments of the present application will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to explain and illustrate the present application, and are not used to limit the present application.

[0037] The present application discloses a continuous production line for enameled wire, such as Figures 1-17As shown, including V-type paint wrapping machine, vertical cyclone drying device 200 and reciprocating sliding type winding device 300, one or more metal wires unwound from the wire unwinder pass through the V-type paint wrapping machine and the vertical cyclone drying device 200 in turn, and are wound on the reciprocating sliding type winding device 300. The V-type paint wrapping machine of the present application comprises a V-type paint coating mechanism 100, an inclination adjusting mechanism, i.e. two wire guide mechanisms, wherein the V-type paint coating mechanism 100 is connected together with the rack through the inclination adjusting mechanism, and the two wire guide mechanisms are respectively connected at the import and export ends of the V-type paint coating mechanism 100. The present application can determine whether cooling is needed according to the temperature of the metal wire after passing through the vertical cyclone drying device 200. Generally, air cooling is used for cooling to avoid the case that the paint is dry and cracked under thermal stress before the temperature of the metal wire changes sharply. The working principle and advantages of the present application are as follows: the present application continuously coats the paint on one or multiple metal wires in parallel through the V-type paint wrapping machine, and then the metal wires are wound on one or multiple winding drums on the reciprocating sliding type winding device 300 after drying through the vertical cyclone drying device 200. The V-type paint coating mechanism 100 of the V-type paint wrapping machine adopts V-shaped design, and the inclination angle of the V-type paint coating mechanism 100 is adjusted through the inclination adjusting mechanism, so as to ensure that the paint can fully adhere to the surface of the metal wire during the process of passing through the V-type paint coating mechanism 100, and to ensure the uniformity and expected thickness of the paint layer, avoiding the cases that the paint layer is not uniform in thickness, or the paint layer is too thin or too thick. If the paint layer is too thin, the insulation performance of the metal wire is low, and if the paint layer is too thick, the weight of the metal wire is large, and the consumption of the paint increases sharply, increasing the processing cost. Moreover, after adjusting the inclination angle of the V-type paint coating mechanism 100, the two wire guide mechanisms can smoothly and smoothly guide the metal wire into and out of the V-type paint coating mechanism 100, playing the role of guiding and transitioning the metal wire. The present application adopts the vertical cyclone drying device 200, the metal wire passes through the vertical cyclone drying device 200 along the vertical direction, and the drying gas flows through the vertical cyclone drying device 200 along the vertical direction, improving the contact time and comprehensiveness of the contact between the drying gas and the metal wire, and further making the outer surface of the metal wire be fully dried. One or multiple winding drums are installed on the reciprocating sliding type winding device 300, and one or multiple metal wires are wound on the corresponding winding drums after drying, and the metal wires are uniformly wound during the reciprocating movement of the reciprocating sliding type winding device 300. In summary, the present application can effectively improve the comprehensiveness of the paint coating on the surface of the metal wire, ensure that the outer surface of the metal wire has excellent insulation, and make the paint quickly dry and solidify on the metal wire, improve the drying efficiency, reduce the energy consumption of the equipment, and reduce the space occupied by the equipment.
