Description

Technical Field

[0001] This utility model relates to the field of enameled wire coating technology, and in particular to a nitrogen-free solvent-based polyamide-imide enameled wire coating device. Background Technology

[0002] Enameled wire is a major type of winding wire, widely used in refrigerator compressors, air conditioner compressors, power tools, explosion-proof motors, and motors used under conditions such as high temperature, extreme cold, radiation resistance, and overload. Enameled wire consists of two parts: a conductor and an insulation layer. The bare wire is annealed and softened, and then coated with enamel multiple times and baked by coating equipment. There are many types of coating equipment, including roller coating and spray coating.

[0003] In the prior art, when spray coating equipment coats enameled wires, it is easy to cause excessive coating. In order to prevent the excess paint from damaging the inside of the coating equipment, a recycling mechanism is generally set up inside the coating equipment. This setting makes it inconvenient to remove the recycled paint. The removal process is cumbersome and complicated, wasting time and effort, and reducing the practicality and convenience of spray coating equipment. Utility Model Content

An electric push rod 21 is fixedly installed on the upper surface of the mounting frame 2, and the electric push rod 21 penetrates the upper surface of the mounting frame 2.

The fixing bolt 26 penetrates the side wall of the fixing frame 22 and is inserted into the side wall of the uniform distribution block 23.

[0030] By setting up a support frame 20, an electric push rod 21, a fixing frame 22, a uniform distribution block 23, a locking block 24, a locking groove 25, and a fixing bolt 26, the function of conveniently and quickly assembling and disassembling the uniform distribution block 23 is realized. This improves the installation method of the uniform distribution block 23 in the existing technology, making it quick and easy to assemble and disassemble the uniform distribution block 23, thereby facilitating the replacement of the uniform distribution block 23. On the basis of the original, the convenience of the coating equipment is further improved.

[0031] Working principle: When coating enameled wire using the coating equipment, the enameled wire is first passed through the mounting frame 2, so that it is placed on the two guide rollers 8. The enameled wire passes through the inside of the liquid circulation ring 6 and is placed between the two uniform distribution blocks 23. Then, the electric actuator 21 is activated to control its extension. When the electric actuator 21 extends, it drives the uniform distribution blocks 23 above to descend through the fixing frame 22, so that the two uniform distribution blocks 23 move closer to each other. When the two uniform distribution blocks 23 contact each other, the enameled wire is placed in the grooves on the two enameled wires. Inside, the pump 4 is then started. When the pump 4 is running, it draws the paint from the inside of the storage tank 3 through the pump pipe, and then guides the paint into the inside of the liquid ring 6 through the liquid pipe 5. The paint is then sprayed out through the atomizing nozzle 7, spraying the paint onto the outer surface of the enameled wire. At the same time, the enameled wire is pulled so that it extends from the left end of the mounting bracket 2 to the right end of the mounting bracket 2. During the extension of the enameled wire, it passes through the grooves on the two uniformly distributed blocks 23, and the uniformly distributed blocks 23 spread the paint evenly on the enameled wire.

[0032] During the coating process of enameled wire, excess paint drips down into the inside of the recycling box 9 and flows down through the leakage hole, eventually flowing into the inside of the recycling box 11. As the paint flows into the recycling box 11, it passes through the filter screen 18, which filters out impurities. When too much paint accumulates inside the recycling box 11, the pull plate 14 is pulled, causing the two positioning rods 13 to extend away from the fixed frame 10, stretching and deforming the tension spring 15. After the positioning rods 13 separate from the slider 12, the fixing of the recycling box 11 is released, and then the recycling box 11 is pulled outwards, causing the recycling box 11 to remain within the fixed frame 10. The slider 12 slides inside the slide groove. When the slider 12 slides out of the slide groove, the recycling box 11 separates from the fixed frame 10. Then, the mounting frame 17 is pulled upward, so that the mounting frame 17 slides upward inside the mounting groove 16. The limiting block 19 slides inside the limiting groove. When the mounting frame 17 slides out of the mounting groove 16, the filter screen 18 is disassembled. At this time, the paint inside the recycling box 11 can be treated. During this process, the disassembled filter screen 18 can also be cleaned or replaced. After the paint treatment is completed, the above operation is reversed, and the recycling box 11 is reinstalled into the fixed frame 10.

[0033] When replacing the uniform distribution block 23, first loosen the fixing bolts 26 on the two fixing brackets 22, so that the fixing bolts 26 extend away from the fixing brackets 22. After the fixing bolts 26 separate from the uniform distribution block 23, release the fixation of the uniform distribution block 23. Then pull the two uniform distribution blocks 23 so that the two uniform distribution blocks 23 slide out of the fixing brackets 22. The locking block 24 slides inside the locking groove 25. After the locking block 24 slides out of the locking groove 25, the disassembly of the uniform distribution block 23 is completed. Then take out two matching new uniform distribution blocks 23 and reverse the above operation to fix the two new uniform distribution blocks 23, thus completing the replacement of the uniform distribution block 23. During the replacement process, the uniform distribution block 23 with the groove specification can also be selected for replacement based on the thickness of the enameled wire.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
