Description

TECHNICAL FIELD

[0001] The utility model relates to heating roller technical field, concretely relates to a kind of multistage gradient type energy-saving heating roller structure for enameled wire coating machine. BACKGROUND

[0002] ‌Enameled wire is a main variety of winding wire, which is composed of a conductor and an insulating layer. After annealing and softening, the bare wire is coated with paint multiple times and baked to form an enameled wire. However, it is not easy to produce a product that meets 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 mechanical properties, chemical properties, electrical properties, and thermal properties. Enameled wire is a main raw material for products such as motors, electrical appliances, and household appliances. To improve the winding efficiency of enameled wire, manufacturers continuously increase the winding speed, which requires reducing the friction coefficient of enameled wire. Therefore, a process of coating the finished enameled wire with a lubricant is needed. The main coating material is paraffin wax. Since the melting point of paraffin wax is around 60°C, it is solid at room temperature and cannot be evenly coated on the enameled wire. The common practice is to dissolve paraffin wax in liquid cyclohexane to prepare a mixed lubricating liquid, and then apply it to the finished enameled wire through a dripping method.

[0003] After searching, a kind of enameled wire hot wax automatic coating device (publication number: CN214320685U) is disclosed in the prior art. The top of the machine is fixedly installed with an adjusting device. The inside of the adjusting device includes a fixed table, a rotating shaft is arranged inside the fixed table, one end of the rotating shaft is movably connected with the inner wall of the fixed table, the other end of the rotating shaft is fixedly connected with an adjusting plate, the end of the adjusting plate away from the rotating shaft is provided with an adjusting shaft, one end of the adjusting shaft is movably connected with one end of the adjusting plate, and the outer wall of the adjusting shaft is movably connected with a heating roller. The device can rotate and tighten the enameled wire through the adjusting device, control the feeding speed of the enameled wire, and the enameled wire passes through the adjusting device. The rotating shaft can drive the adjusting plate to rotate, the adjusting plate drives the adjusting shaft to move, and the heating roller outside the adjusting shaft can preheat the enameled wire. When the enameled wire is too long, the adjusting plate drives the heating roller to rotate, clamps and fixes the enameled wire, and the heating roller can prevent the paraffin wax from rapidly solidifying when it contacts the enameled wire. The uneven distribution of the enameled wire affects the product quality, but the heating area on the surface of the heating roller in the device cannot be graded, so that the same batch of heating rollers can only use one temperature to heat the paraffin wax on the outside of the enameled wire, which leads to the fact that the paraffin wax cannot gradually wrap and solidify on the outside of the enameled wire through the corresponding temperature change curve, and the heat in some areas of the surface of the heating roller is wasted because it does not contact the enameled wire. This is not conducive to the energy saving of the heating roller, and the use of the heating roller in the device is not flexible enough. UTILITY MODEL CONTENT
