Description

Technical Field

[0001] This utility model relates to the technical field of enameled wire production equipment, and in particular to an online surface lubricant coating device for enameled wire. Background Technology

[0002] Enameled wire, a key type of winding wire, consists of a conductor and an insulation layer. Its production process includes annealing and softening the bare wire, followed by multiple coatings and baking. However, producing enameled wire that meets standards and customer requirements is quite challenging. This is because its quality is affected by many factors, such as the quality of raw materials, process parameters, production equipment, and environment, resulting in different quality characteristics for different enameled wires. However, they generally encompass four key properties: mechanical properties, chemical properties, electrical properties, and thermal properties.

[0003] In the actual production of enameled wire, applying lubricant to its surface using a coating device is a crucial step. In the past, the lubricant coating process for enameled wire has frequently encountered difficulties. On the one hand, if the enameled wire bends during coating, the coating effect is easily compromised, failing to ensure that the lubricant evenly and completely covers the wire surface, thus affecting subsequent processing and product quality. On the other hand, after coating, the lubricant dripping from the enameled wire often falls directly to the ground, not only causing unnecessary waste of precious lubricant resources but also contradicting current environmental protection principles and potentially causing environmental pollution problems.

[0004] Although existing technologies have explored solutions to these problems, such as the online surface lubricant coating device for enameled wire disclosed in Chinese utility model patent CN 112295792 A, which alleviates some of the difficulties to a certain extent, significant shortcomings still exist. During the coating operation, this device struggles to achieve comprehensive, seamless coating of the enameled wire, resulting in insufficient lubrication on some wire surfaces and affecting the overall product performance. Furthermore, the device lacks an efficient drainage mechanism for excess lubricant generated during the coating process, failing to promptly remove it. This leads to lubricant accumulation within the device, interfering with the coating process and hindering the continuous and stable operation of the equipment. It is ill-suited to the practical need for rapid online surface lubricant coating of enameled wire, and a more optimized coating device is urgently needed to overcome these challenges.

The lower inlet of the exhaust fan 8 is connected to the upper right opening of the coating cavity 2.

[0021] like Figure 2 and Figure 3As shown, the specific structure of the liquid feeding mechanism 4 includes a motor 41, a mounting base 42, a driving gear 43, a driven gear 44, a movable tube 45, a flow guide 46, a liquid feeding hole 47, a transmission gear 48, an annular inner groove 49, a screw rod 410, a conveying hole 411, a liquid inlet hole 412, a liquid outlet hole 413, and a second drain hole 414. The mounting base 42 is fixedly connected to the left side of the coating chamber 2. The top of the mounting base 42 is fixedly connected to the motor 41, and the driving gear 43 is fixedly connected to the output shaft of the motor 41. The lower side of the mounting base 42 has a vertical conveying hole 411 inside, and the right side of the central inner wall of the mounting base 42 has an annular inner groove 49. The left side of the movable tube 45 is movably connected to the center of the mounting base 42. Several flow guides 46 are fixedly connected to the left side of the movable tube 45. 5. Several drainage holes 414 are provided around the right side. A driven gear 44 is fixedly connected to the outside of the left side of the movable tube 45, and the upper side of the driven gear 44 is connected to the driving gear 43. The outside of the right side of the movable tube 45 is movably connected to the inside of the left opening of the coating guide hole 10. There are several liquid inlet holes 47, which are all located inside the annular inner groove 49 and are evenly distributed around the inside of the left side of the movable tube 45. A spiral rod 410 is movably connected inside the conveying hole 411, and a transmission gear 48 is fixedly connected to the upper end of the spiral rod 410. The transmission gear 48 is connected to the lower side of the driven gear 44. A liquid outlet hole 413 is provided on the upper right side of the conveying hole 411, and the upper opening of the liquid outlet hole 413 is connected to the inside of the annular inner groove 49. Several liquid inlet holes 412 are provided around the lower side of the conveying hole 411.

[0022] The motor 41 is a servo motor or a variable frequency motor; the top surface of the guide plate 3 is a slope that is higher on the left and lower on the right; air filters are provided at the upper inlet of the fan 6 and the upper outlet of the exhaust fan 8.

[0023] The utility model is used as follows: It features a reasonable and simple structure, low production cost, convenient installation, and complete functions. In use, the enameled wire first enters the coating chamber 2 through the wire hole 9 on the left side, preparing for lubricant coating. Then, the motor 41 is started. The output shaft of the motor 41 drives the drive gear 43 to rotate. The drive gear 43 meshes with the driven gear 44, causing the movable tube 45 to rotate inside the center of the mounting base 42. The left side of the movable tube 45 is movably connected to the mounting base 42, and the right side is movably connected to the inside of the left opening of the coating guide hole 10. The driven gear 44 drives the transmission gear 48 to rotate, thereby causing the spiral rod 41 to rotate. The lubricant rotates within the delivery hole 411. The inlet holes 412 around the lower side of the delivery hole 411 draw lubricant from the coating chamber 2 into the delivery hole 411. The lubricant then flows into the annular inner groove 49 through the outlet hole 413, and enters the interior of the movable tube 45 through the upper liquid hole 47 on the left side. The guide shroud 46 on the left side inside the movable tube 45 directs the incoming lubricant towards the center, ensuring full contact with the outer perimeter of the enameled wire within the movable tube 45. This achieves complete encapsulation of the enameled wire by the lubricant. Simultaneously, the rotation of the movable tube 45 causes the lubricant to move around the enameled wire, ensuring full contact between the wire and the lubricant. As the enameled wire moves to the right and the lubricant... As the lubricant continues to flow, excess lubricant enters the right side of the movable tube 45. The drainage holes 414 around the right side of the movable tube 45 rotate, quickly dislodging most of the excess lubricant. The remaining lubricant on the surface of the enameled wire enters the coating guide hole 10 along with the wire. The coating membrane 12 inside the coating guide hole 10 coats the enameled wire and scrapes off excess lubricant. The blower 6 is then started. The lower outlet of the blower 6 connects to the cavity 7 inside the center of the fixed base 5. The connecting hole 11 at the bottom of the cavity 7 connects to the inside of the coating guide hole 10. The airflow generated by the blower 6 forces the scraped lubricant through the drainage hole 13 on the bottom surface of the coating guide hole 10. The lubricant is blown out, improving the efficiency of excess lubricant discharge. The guide plate 3 on the lower left side of the coating chamber 2 is a sloped surface with the left side higher than the right side, which can guide the lubricant in the coating chamber 2 to the filter screen 14 on the lower right side, which plays the role of filtering and collecting the lubricant. The enameled wire that has completed coating and removal of excess lubricant is output through the wire hole 9 on the right side for the next processing. Air filters are provided at the upper inlet of the blower 6 and the upper outlet of the exhaust fan 8 to filter the incoming and outgoing air, ensuring the cleanliness of the air inside the device, preventing impurities from entering and affecting the coating effect or damaging the device, and also preventing the exhaust gas from containing impurities such as lubricant and polluting the environment.
