technical field

The invention relates to a heating device, in particular to a paint heating device for enameled wire production.

Background technique

Enameled wire is the most representative product among electronic wires. Enameled wire is a main variety of winding wire, including the core wire and the paint layer coated on the outside of the core wire. After the bare wire is annealed and softened, it is painted and baked many times. It has four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties. The production process of enameled wire includes the steps of core wire processing, finished product drawing, painting, packaging and storage. The painting process includes pulling, annealing, painting, baking, cooling, winding, and packaging and storage after passing the inspection. Among them, in the painting process, the paint needs to be preheated to 45°C-50°C. Usually, the paint box is used for heating, and the painted wire is baked by a temperature-controlled oven, which consumes a lot of power.

More preferably, the hot water pipe is provided with a thermometer at a position connected to the cold water pipe.

Further, the outer side of the hot water pipeline passing through the baking insulation layer is wrapped with the pipeline insulation layer.

Baking is to evaporate the solvent in the paint liquid coated on the wire core through high-temperature drying, and then solidify to form a paint film, put the wire on the baking tray for baking, and the baking insulation layer is to keep the baking tray warm, so that the temperature is uniform Hengwen, due to the adoption of the above technical scheme, the paint heating device of the present invention directly uses the baking insulation layer of the baking device to heat the water, and then the water heats the paint, which saves the paint box used for heating the paint, and at the same time The excess heat energy is utilized, which not only reduces the cost, but also saves electric energy. The paint is heated by flow, which improves the efficiency. The paint heating temperature is adjusted by adjusting the mixing ratio of cold and hot water. The operation is convenient and the device structure is simple. easy and convenient.

Detailed ways

The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

With reference to accompanying drawing 1, the paint heating device in the present embodiment, it comprises baking tray 1, baking insulation layer 2, hot water pipeline 3, cold water pipeline 4, regulating switch 8 and paint pipeline 5, and baking insulation layer 2 is positioned at baking tray 1 Below, the hot water pipe 3 passes through the baking insulation layer 2, the cold water pipe 4 is connected with the hot water pipe 1, and the paint pipe 5 is inserted into the hot water pipe 3 inside.

In this embodiment, galvanized iron pipes are used for the paint pipes to avoid adhesion between the paint and the inner wall of the pipes. The hot water pipes and cold water pipes are made of PP-R water pipes with better high temperature resistance, and pipes of other materials can also be selected according to the actual situation.

Baking is to evaporate the solvent in the paint liquid coated on the wire core through high-temperature drying, and then solidify to form a paint film, put the wire on the baking tray 1 to bake, and the baking insulation layer 2 is to keep the baking tray 1 warm, so that The temperature is uniform and stable. The baking insulation layer 2 selects asbestos, a commonly used insulation material, which has good insulation effect and low cost.

The temperature of each position of the baking insulation layer 2 is different, and in the enamelled wire painting process, the paint preheating temperature is 45°C-50°C, so before installing the device, it is necessary to measure the temperature of each position of the baking insulation layer 2, Then choose the position where the temperature is above 50°C to install the hot water pipeline 3 .

The asbestos insulation layer is used for a long time, and the temperature of each position is basically constant, and the service time of the asbestos insulation layer is shorter, and the temperature of each position will change. The cold water pipes 4 are connected to mix the cold water and hot water, and the mixing ratio of the hot and cold water is adjusted by adjusting the switch 8 to control the water temperature, that is, the heating temperature of the paint, so that the temperature is maintained at 45°C-50°C. In this embodiment, the regulating switch 8 is arranged on the cold water pipe 4, and the temperature is controlled by regulating the flow of cold water. It is also possible to set a regulating switch 8 on the hot water pipe 3 to control the flow of hot water. 3. A two-way regulating switch is arranged at the joint of the cold water pipe 4 to regulate the flow of cold water and hot water at the same time.

The position where the paint pipe 5 is inserted into the hot water pipe 3 is behind the position where the hot water pipe 3 and the cold water pipe 4 join. The hot water pipeline 3 is provided with a thermometer 7 at the position behind the cold water pipeline 4, so as to monitor the temperature in real time. The outside of the hot water pipe is wrapped with a pipe insulation layer to ensure that the water temperature after mixing the hot and cold water is kept at 45°C-50°C, that is, to ensure that the paint temperature is kept at 45°C-50°C.

The outside of the pipeline at one end where the hot water flows out of the baking insulation layer is wrapped with a pipeline insulation layer 6, which is also asbestos.

As can be seen from the above examples, the paint heating device of the present invention adopts flow heating, which is an instant heating method, improves production efficiency, and directly utilizes the baking insulation layer 2 of the baking device for heating, eliminating the need for heating. The lacquer box used for painting utilizes the excess heat energy of baking at the same time, which not only reduces the cost, but also saves energy. The device has a simple structure, is convenient to operate, and is simple and convenient to implement.

The above embodiments are only to illustrate the technical concept and characteristics of the present invention. All equivalent changes or modifications shall fall within the protection scope of the present invention.
