In the production process of the enameled wire, various quality problems are frequently generated, and defective products are generated, wherein the surface of the enameled wire is subjected to puckery processing, which is one of the most common quality problems, and the viscosity of the enameled wire is an important process parameter influencing whether the surface of the enameled wire is subjected to puckery processing. When the viscosity of the wire enamel is too high, the fluidity of the wire enamel is poor, and uneven painting on the surface of the conductor is easily caused, so that the surface of the wire enamel is unsmooth, and the production process of the wire enamel requires that the viscosity of the wire enamel is within a certain range. In the actual production process, especially when producing big specification enameled wire under summer high temperature environment, the temperature of enameled wire conductor is higher, and it passes through circulation lacquer liquid with the heat and transmits to the paint box in continuous multichannel japanning in-process, causes the paint box high temperature to lead to the too fast evaporation of solvent of enameled wire lacquer in the paint box, finally cause the viscosity increase of enameled wire, enameled wire product surface is puckery. Therefore, when large-scale enameled wires are produced at high temperature in summer, the temperature of the paint box is controlled, the temperature of paint liquid in the paint box is ensured to be within a reasonable range, and the improvement of the surface quality of the enameled wires is very necessary.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

As shown in fig. 1, the paint box cooling device provided by the utility model comprises a box body and a water supply mechanism, wherein the box body comprises a paint box 6 and a sealing cover 7, and the sealing cover 7 is arranged outside the paint box 6; the water supply mechanism comprises a water pump 8 and a water tank 9, and the water pump 8 is connected with the water tank 9 through a first water pipe 1; wherein, the outside of sealed cowling 7 is provided with water inlet 4, and water inlet 4 passes through second water pipe 2 to be connected in water pump 8, and the outside of sealed cowling 7 still is provided with delivery port 5, and delivery port 5 is connected to basin 9 through third water pipe 3. Under the continuous work of the water pump 8, cooling water flows from the water tank 9, flows through the box body and finally returns to the water tank 9; in the working process, the cooling water takes away the heat accumulated at the box body, so that the temperature of the paint box 6 is controlled, and the temperature of the paint liquid in the paint box 6 is ensured to be within a reasonable range.

In the above embodiment, the sealing cover 7 and the paint box 6 are of an integral sealing structure. At the joint of the sealing cover 7 and the paint box 6, a welding or top capping mode is adopted to form a closed cavity between the sealing cover 7 and the paint box 6, and the cooling liquid completes heat exchange with the paint box 6 in the cavity. The integrated sealing structure can prevent foreign matters in the working environment from falling into the cavity between the sealing cover 7 and the box body, and the influence on heat dissipation is reduced.

Wherein, the position of the water outlet 5 arranged on the sealing cover is higher than the position of the water inlet 4. Delivery port 5 and water inlet 4 set up on the same lateral wall of sealed cowling, perhaps set up respectively on two adjacent or relative lateral walls of sealed cowling, and the horizontal position of delivery port 5 is higher than the horizontal position of water inlet 4, and when delivery port 5 was higher than the setting of water inlet 4, the cooling water can fill the cooling zone completely to can also play the effect that slows down the velocity of flow of cooling water, in order to reach better cooling effect.

Preferably, the cooling water contained in the water tank 9 is purified water. According to the working environment of enameled wire production, common special pure cooling water can be preferentially adopted, so that the influence on the normal operation of a paint box cooling device due to water quality is avoided; other cooling fluids meeting the requirements of industrial production environments can also be used.

Specifically, in the present embodiment, a heat dissipation water pipe 10 is disposed between the sealing cover 7 and the paint box 6, and the heat dissipation water pipe 10 is disposed in close contact with the paint box 6. As shown in fig. 2, the heat dissipation water pipes 10 are disposed around and at the bottom of the paint box 6, and the cooling water flows through the heat dissipation pipes to transfer heat and lower the temperature of the paint box. According to different production and processing technologies and installation and debugging technologies, a metal radiating pipe can be bent into a certain shape to be close to the paint box 6; a temperature-resistant heat dissipation hose can also be fixed on the inner side of the sealing cover 7, and the heat dissipation water pipe 10 is tightly attached to the paint box 6 after the sealing cover 7 and the paint box 6 are assembled. The water inlet of the heat dissipation water pipe 10 is connected with the water inlet 4 arranged on the sealing cover 7, and the water outlet of the heat dissipation water pipe 10 is connected with the water outlet 5 arranged on the sealing cover 7.

Optionally, in other embodiments, baffles are provided between the sealing boot 7 and the paint box 6. As shown in fig. 3, when the baffle plate is arranged, the cooling liquid is injected from the water inlet 4 arranged on the sealing cover 7 and flows out from the water outlet 5 arranged on the sealing cover 7, in the process, the cooling liquid directly fills the cavity between the sealing cover 7 and the paint box 6, and the cooling liquid and the paint box 6 have the largest heat dissipation contact area. According to the data fed back by the paint liquid temperature sensor in the paint box 6 and the adjustment of the production state in the actual production process, the flow rate of the cooling water is adjusted in real time, so that the paint liquid in the paint box 6 is controlled more accurately, and the temperature of the paint liquid in the paint box 6 is ensured to be within a reasonable range; when the baffle plate is used, the joint of the sealing cover 7 and the paint box 6 needs certain sealing performance to prevent the cooling liquid from leaking. When the paint box cooling device is stopped for maintenance and repair, the cooling liquid in the cavity between the sealing cover 7 and the paint box 6 can be discharged through the cleaning port 13 arranged on the sealing cover 7.

The baffle plate comprises a plurality of inserting plates 12 arranged on the paint box 6 at intervals and a plurality of partition plates 11 arranged on the sealing cover 7 at intervals, the free ends of the inserting plates 12 are inserted between the adjacent partition plates 11, and the free ends of the partition plates 11 are inserted between the adjacent inserting plates 12. The inserting plate 12 arranged on the paint box 6 and the partition plate 11 arranged on the sealing cover 7 play roles of slowing down the flow rate of cooling water, changing the flow direction of the cooling water, increasing the heat dissipation area of the paint box 6 and the like, so that more heat is transferred between the paint box 6 and the cooling water in unit time.

Further, the tank body surface of the water tank 9 is provided with a heat radiating member. When the enamelling machine carries out the production operation for a long time, the heat of the enamelling machine 6 is continuously transmitted to the water tank 9 through the cooling device of the enamelling machine 6, at the moment, the temperature of the cooling water of the water tank 9 is also increased, and the temperature accumulated by the water tank 9 can be accelerated to be diffused to the air environment through the heat dissipation element arranged on the surface of the tank body of the water tank 9.
