Technical Field

[0001] This invention relates to the technical field of coating apparatus, specifically to an insulating coating apparatus for electromagnetic wire processing. Background Technology

[0002] Insulating coatings, also known as insulating paints, are coatings with excellent electrical insulation properties. They possess good electrochemical, thermal, mechanical, and chemical properties, and are mostly varnishes, but colored paints are also available. Insulating varnish is a special type of paint. Based on high-molecular polymers, insulating varnish is an important insulating material that can cure into an insulating film or insulating whole under certain conditions. Insulating varnish is composed of base materials, flame retardants, curing agents, pigments, fillers, and solvents. This article details its composition, usage classifications, grade classifications, requirements, and development trends. A Chinese patent document with publication number CN109926234B discloses an ultra-fine electromagnetic wire insulating varnish spraying device. The device includes a coating tank, a first spraying pipe, a second spraying pipe, and an ultra-fine electromagnetic wire body. The coating tank has a coating inlet, and a groove is formed in the middle section of the coating tank. A sliding rod is movably connected within the groove. Both the first and second spraying pipes have through holes and are semi-annular cylindrical structures. Limiting rods are welded to opposite sides of both the first and second spraying pipes. Limiting grooves are provided on the opposite side of the first and second spraying pipes. Connecting blocks are welded to the outer side walls of the first and second spraying pipes. Connecting screws are screwed into the connecting blocks. Fixed screw rings are screwed into both ends of the connecting screws. A flexible connecting pipe is provided through the inner wall of the paint can. The middle of the flexible connecting pipe is an inner cavity. A bottom groove is provided at the bottom end of the flexible connecting pipe. A connecting groove is provided on the outer wall of the bottom groove. A connecting rod is snapped into the connecting groove. The connecting rod is welded to both sides of the connector. The connector is welded to the upper end of the spraying head. However, the spraying device in the above scheme does not recycle excess insulating coating, and the insulating coating is prone to spreading during the spraying process. This not only wastes the insulating coating, but also pollutes the workshop environment, thereby endangering the health of the workers. Therefore, this invention proposes an insulating coating device for electromagnetic wire processing to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide an insulating coating apparatus for electromagnetic wire processing, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an insulating coating device for electromagnetic wire processing, comprising: The base has a mounting bracket fixedly installed on it. The lower end of the mounting bracket is rotatably mounted with a first-level guide wheel via a first-level rotating shaft, and the upper end of the mounting bracket is rotatably mounted with a second-level guide wheel via a second-level rotating shaft. The electromagnetic wire to be coated is unwound by an unwinding mechanism, passes through the first-level guide wheel and the second-level guide wheel in sequence, and is finally wound up by a winding mechanism. A coating mechanism is fixedly mounted on a mounting bracket via a primary connecting frame, and the coating mechanism is used to apply an insulating coating to the electromagnetic wire. The coating mechanism is located on the upper end of the primary guide wheel. The drying mechanism is fixedly mounted on the mounting bracket via a secondary connecting frame. The drying mechanism is used to dry the electromagnetic wire after the insulating coating is applied. The drying mechanism is located above the coating mechanism and below the secondary guide wheel.

[0005] Preferably, the coating mechanism includes a protective shell, a top cover, and a coating spray gun. The protective shell is funnel-shaped, with a lower channel formed at its lower end. An installation groove is provided on the side wall of the protective shell, and the coating spray gun is fixedly installed in the installation groove. The top cover is fixed to the upper port of the protective shell by a primary positioning bolt, and an upper channel is formed on the top cover. The electromagnetic wire to be coated passes through the lower channel, is sprayed by the coating spray gun in the inner cavity of the protective shell, and passes through the upper channel.

[0006] Preferably, the lower end face of the protective shell is provided with a drain port, and a drain pipe is fixedly connected to the lower end of the drain port. The drain pipe is connected to the waste liquid recovery tank.

[0007] Preferably, five coating spray guns are arranged around the circumference of the protective shell, and the port of the coating spray gun is oriented towards the electromagnetic wire to be coated, and the inner end of the coating spray gun is inclined downward.

[0008] Preferably, a cleaning cotton is provided on the inner side wall of the lower channel, and an engaging groove is formed on the inner side wall of the lower channel. An engaging protrusion is integrally formed on the outer side wall of the cleaning cotton. When the cleaning cotton is actually installed, the engaging protrusion is embedded in the engaging groove. When the electromagnetic wire passes through the cleaning cotton, the cleaning cotton and the side wall of the electromagnetic wire are abutted together.

[0009] Preferably, an annular nozzle is fixedly installed on the outer wall of the upper channel by a secondary positioning bolt. The liquid inlet of the annular nozzle is connected to the water supply equipment through a connecting pipe. Spray holes are evenly opened on the outer wall of the annular nozzle, and the spray holes are set towards the inner wall of the protective shell.

[0010] Preferably, the spray holes are provided in two layers, and the two layers of spray holes are staggered, and the spray holes spray at low pressure when spraying liquid.

[0011] Preferably, both the primary and secondary rotating shafts are driven by a drive motor, and the linear speed of the primary and secondary rotating shafts is the same as the winding and unwinding speed of the electromagnetic wire.

[0012] Preferably, a transmission gear is fixedly installed at the end of the primary shaft, a third shaft is rotatably installed on the mounting bracket, a driven gear and a transmission wheel are fixedly installed on the third shaft, the driven gear meshes with the transmission gear, and a striking mechanism is fixedly installed on the outer wall of the transmission wheel.

[0013] Preferably, the striking mechanism includes a connecting spring and an impact head. The connecting spring is fixedly connected to the outer wall of the transmission wheel. The impact head has a hemispherical structure and is fixedly connected to the outer end of the connecting spring. When the transmission wheel rotates, the spherical surface of the impact head collides with the outer wall of the protective shell.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up an insulating coating coating device for electromagnetic wire processing, which consists of a base, a coating mechanism and a drying mechanism, and setting the coating mechanism to consist of a protective shell, a top cover and a coating spray gun, when the coating spray gun sprays the electromagnetic wire, the protective shell and top cover can block the diffusion of the mist coating material, thereby effectively preventing the diffusion of the mist coating material. In addition, the overall size of the protective shell and top cover is small, which facilitates the recycling of the diffused mist coating material, thereby facilitating its reprocessing and reuse, and reducing material waste. 2. By installing an annular nozzle on the outer wall of the upper channel on the top cover, water is sprayed onto the inner wall of the protective shell through the annular nozzle, thereby preventing the mist coating from drying and solidifying on the inner wall of the protective shell, thus effectively ensuring the recycling effect of the mist coating. 3. The transmission wheel drives the connecting spring, which in turn causes the impact head to collide with the protective shell, allowing the mist coating on the inner wall of the protective shell to be better retained. This prevents the mist coating from adhering for a long time and drying out, thus further ensuring the recycling effect of the mist coating. Moreover, this process does not require an additional power source, making it convenient for routine circuit inspection and maintenance of the equipment. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-11 The present invention provides the following three preferred embodiments: Example 1: An insulating coating device for processing electromagnetic wire includes a base 1, a coating mechanism 2, and a drying mechanism 3. A mounting bracket 4 is fixedly mounted on the base 1. A primary guide wheel 6 is rotatably mounted on the lower end of the mounting bracket 4 via a primary rotating shaft 5. A secondary guide wheel 8 is rotatably mounted on the upper end of the mounting bracket 4 via a secondary rotating shaft 7. The electromagnetic wire 11 to be coated is unwound by the unwinding mechanism, passes sequentially through the primary guide wheel 6 and the secondary guide wheel 8, and is finally wound up by the winding mechanism. The coating mechanism 2 is fixedly mounted on the mounting bracket 4 via a primary connecting frame 9 and is used to apply an insulating coating to the electromagnetic wire 11. The coating mechanism 2 is located above the primary guide wheel 6. The drying mechanism 3 is fixedly mounted on the mounting bracket 4 via a secondary connecting frame 10. On the bracket 4, the drying mechanism 3 is used to dry the electromagnetic wire 11 after the insulating coating is applied. The drying mechanism 3 is located above the coating mechanism 2 and below the secondary guide wheel 8. The coating mechanism 2 includes a protective shell 12, an upper cover 13, and a coating spray gun 14. The protective shell 12 is bucket-shaped, and a lower channel 16 is formed on the lower end of the protective shell 12. An installation groove 15 is opened on the side wall of the protective shell 12. The coating spray gun 14 is fixedly installed in the installation groove 15. The upper cover 13 is fixed to the upper port of the protective shell 12 by a primary positioning bolt 23. An upper channel 17 is formed on the upper cover 13. The electromagnetic wire 11 to be coated passes through the lower channel 16 and is sprayed by the coating spray gun 14 in the inner cavity of the protective shell 12, and then passes through the upper channel 17.

[0019] The lower end face of the protective shell 12 is provided with a drain port 21, and a drain pipe 22 is fixedly connected to the lower end of the drain port 21. The drain pipe 22 is connected to the waste liquid recovery tank. By setting up an insulating coating device for electromagnetic wire processing, which is composed of a base 1, a coating mechanism 2 and a drying mechanism 3, and setting the coating mechanism 2 to be composed of a protective shell 12, a top cover 13 and a coating spray gun 14, when the coating spray gun 14 sprays the electromagnetic wire 11, the diffused mist coating can be blocked by the protective shell 12 and the top cover 13, thereby effectively preventing the diffusion of the mist coating. In addition, the overall size of the protective shell 12 and the top cover 13 is small, which facilitates the recovery of the diffused mist coating, thereby facilitating its reprocessing and reuse, and reducing material waste.

[0020] Example 2: Please refer to Figure 1 and Figures 4-11 Based on Embodiment 1, five coating spray guns 14 are arranged around the protective shell 12, and the port of the coating spray gun 14 is set towards the electromagnetic wire 11 to be coated. The inner end of the coating spray gun 14 is set downward. The five angles are sprayed simultaneously to ensure the complete coverage of the electromagnetic wire 11 surface, thereby effectively ensuring the product quality of the electromagnetic wire 11.

[0021] A cleaning cotton 19 is provided on the inner side wall of the lower channel 16, and a locking groove 18 is provided on the inner side wall of the lower channel 16. A locking protrusion 20 is integrally formed on the outer side wall of the cleaning cotton 19. When the cleaning cotton 19 is actually installed, the locking protrusion 20 is embedded in the locking groove 18. When the electromagnetic wire 11 passes through the cleaning cotton 19, the cleaning cotton 19 is set to abut against the side wall of the electromagnetic wire 11. The surface of the electromagnetic wire 11 is cleaned by the cleaning cotton 19, thereby ensuring the surface cleanliness of the electromagnetic wire 11.

[0022] An annular nozzle 24 is fixedly installed on the outer wall of the upper channel 17 by a secondary positioning bolt 25. The liquid inlet of the liquid chamber 26 of the annular nozzle 24 is connected to the water supply equipment through a connecting pipe 27. Spray holes 28 are evenly opened on the outer wall of the annular nozzle 24, and the spray holes 28 are set facing the inner wall of the protective shell 12. By installing the annular nozzle 24 on the outer wall of the upper channel 17 on the upper cover 13, water is sprayed onto the inner wall of the protective shell 12 through the annular nozzle 24, thereby preventing the mist coating from drying and solidifying on the inner wall of the protective shell 12, thus effectively ensuring the recovery effect of the mist coating.

[0023] The spray nozzles 28 are provided in two layers, and the two layers of spray nozzles 28 are staggered, which can improve the spray coverage effect of the spray nozzles 28. In addition, the spray nozzles 28 spray at low pressure, which can avoid splashing water and affecting the coating process of the insulating coating.

[0024] Both the primary shaft 5 and the secondary shaft 7 are driven by a drive motor, and the linear speed of the primary shaft 5 and the secondary shaft 7 is the same as the winding and unwinding speed of the electromagnetic wire 11, so as to avoid relative friction between the electromagnetic wire 11 and the primary shaft 5 and the secondary shaft 7 and damage thereto.

[0025] Example 3: Please refer to Figures 2-3 Based on Embodiment 2, a transmission gear 29 is fixedly installed at the end of the first-stage rotating shaft 5, a third-stage rotating shaft 30 is rotatably installed on the mounting bracket 4, a driven gear 31 and a transmission wheel 32 are fixedly installed on the third-stage rotating shaft 30, the driven gear 31 is meshed with the transmission gear 29, and a striking mechanism is fixedly installed on the outer side wall of the transmission wheel 32.

[0026] The striking mechanism includes a connecting spring 33 and an impact head 34. The connecting spring 33 is fixedly connected to the outer wall of the transmission wheel 32. The impact head 34 has a hemispherical structure and is fixedly connected to the outer end of the connecting spring 33. When the transmission wheel 32 rotates, the spherical surface of the impact head 34 collides with the outer wall of the protective shell 12. The transmission wheel 32 drives the connecting spring 33, thereby causing the impact head 34 to collide with the protective shell 12. This allows the mist coating on the inner wall of the protective shell 12 to be better retained, thus preventing the mist coating from adhering for a long time and drying out. This further ensures the recycling effect of the mist coating. Moreover, this process does not require an additional power source, which facilitates the routine circuit inspection and maintenance of the equipment.
