Description

Technical Field

[0001] The invention belongs to the technical field of enameled wires, and in particular relates to an automatic hot wax coating device for enameled wires. Background Art

[0002] Enameled wire is a main type of winding wire, which consists of a conductor and an insulating layer. The bare wire is annealed and softened, then painted and baked several times. However, it is not easy to produce products that meet both standard requirements and customer requirements. It is affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enameled wires are different, but they all have four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties. Enameled wire is the main raw material for products such as motors, electrical appliances, and household appliances. In particular, the power industry has achieved sustained and rapid growth in recent years, and the rapid development of household appliances has brought a wider application field for enameled wires, and higher requirements have been put forward for enameled wires. In order to improve the winding efficiency of enameled wires and continuously increase the winding speed, enameled wire manufacturers need to reduce the friction coefficient of enameled wires, and need to lubricate the finished enameled wires. The coating raw material is mainly paraffin. Since the melting point of paraffin is around 60° and it is solid at room temperature, it cannot be evenly coated on the enameled wire. The current common practice is to evenly dissolve the paraffin in liquid cyclohexane to prepare a mixed lubricant, and then lubricate and coat the finished enameled wire by dripping.

[0003] For example, a hot wax automatic coating device for enameled wire disclosed in Chinese patent CN104376925B utilizes paraffin heated and melted by an electric heating tube and transported to an oiling bucket through an oil spraying pipe. Compressed air is sent to the oiling bucket through an air jet pipe to atomize the liquid paraffin. The atomized paraffin can be sprayed more evenly on the adsorption felt. The finished enameled wire passes through the adsorption felt to achieve paraffin lubrication coating, thereby achieving the advantages of safety, environmental protection and resource conservation. However, the following problems still exist when using it:

[0004] 1. When the atomized paraffin is sprayed on the adsorption felt, the temperature of the paraffin on the inner wall of the adsorption felt will be relatively reduced, making the outer layer of the paraffin solidified, resulting in a significant reduction in its fluidity on the adsorption felt, and even clogging the felt, making it impossible to carry out the coating work normally.

[0005] 2. Because traditional devices are often unable to coat enameled wires of different diameters and are prone to uneven coating, the quality of the finished product is difficult to control.

[0006] Therefore, we designed an automatic hot wax coating device for enameled wire to solve the above problems. Summary of the invention
