Description

Technical Field

[0001] This invention relates to a lubrication coating machine and coating method for enameled wire, belonging to the field of enameled wire production and processing technology. Background Technology

[0002] Enamelled wire refers to a metallic conductor with an insulating varnish coating used for winding electromagnetic coils; it is also called electromagnetic wire. It is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then undergoes multiple coatings and baking processes. However, producing products that meet both standard requirements and customer demands is not easy. It is affected by factors such as raw material quality, process parameters, production equipment, and the environment. Therefore, the quality characteristics of various enamelled wires differ, but they all possess four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties.

[0003] The lubrication of enameled wire has a significant impact on the tightness of the winding. The lubricant used for enameled wire should be able to make the surface of the wire smooth, without harming the wire, without affecting the strength of the winding spool, and without affecting the user's use. Ideally, the amount of oil applied should be enough to make the enameled wire feel smooth to the touch, but without visible oil on the hand.

[0004] To achieve surface lubrication coating of enameled wire, lubrication coating devices have emerged. The invention patent "A Surface Lubrication Coating Device for Enameled Wire" (application number 201910592193.7) from Guangdong Jingdalia Special Enameled Wire Co., Ltd. includes a base, a coating device body, and a lifting plate. The coating device body has first slide rails fixedly mounted on both sides of its interior. A first slider slides on the surface of the first slide rails. A lifting plate is fixedly mounted on one side of the first slider. A third slide rail is mounted on the upper surface of the lifting plate. A third slider slides on the upper surface of the third slide rail. A scissor structure is located at the upper end of the third slider. A first rotary motor is mounted on the upper end of the scissor structure. A threaded rod is driven on one side of the first rotary motor. A second rotary motor indirectly drives a second rotary shaft and a lubrication coating roller to rotate via a belt and pulley. At this time, the lubrication coating roller comes into contact with lubricating oil, and the coating grooves on its surface are filled with lubricating oil. The enameled wire is then coated through these grooves. Excess lubricating oil is absorbed by an anti-drip absorbent felt to prevent leakage.

[0005] However, with the transport and exhaust of hot air inside the equipment, the lubricating oil in the open oil tank will evaporate excessively, causing it to spread into the production workshop. This makes it difficult to completely solve the problem of lubricating oil evaporation. Furthermore, when transporting enameled wire, the connection of the enameled wire is required, which makes the installation of the enameled wire before traction inconvenient and increases the operational difficulty. Currently, there is no reasonably reliable enameled wire surface lubrication coating machine that has both a function to prevent lubricating oil evaporation and facilitates the connection of enameled wires. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention discloses a lubrication coating machine and method for enameled wire surfaces.

The joint of the first and second combination blocks at the top of the sealing plate is an inclined structure to facilitate a tight fit when the maintenance door is closed. The oil receiving port formed by the first and second combination blocks contains enameled wire. The oil receiving port is a truncated cone hollow structure and is correspondingly located below the clamping block. The bottom of the oil receiving port and the opening at one end of the opening are connected to the inside of the soaking tank.

[0017] The above-mentioned surface lubrication coating machine for enameled wire has a fixed ring and a motor fixedly installed on the top of the machine housing. A rotating shaft is rotatably connected inside the fixed ring. Both the fixed ring and the rotating shaft are circular ring structures. The diameters at both ends of the rotating shaft are larger than the diameter at its center. The rotating shaft is fitted and connected to the inner wall of the fixed ring. A sponge block is fixedly connected inside the rotating shaft. The rotating shaft is sleeved with the enameled wire, and the enameled wire contacts the sponge block. One end of the rotating shaft is provided with a toothed groove. The output end of the motor is fixedly connected to a gear, and the gear meshes with the toothed groove of the rotating shaft.

[0018] The above-mentioned surface lubrication coating machine for enameled wire has a filter box and a purification box fixedly installed on the inner wall of the machine housing. The filter box and the purification box are arranged side by side and fixedly installed with each other. The filter box has a filter screen that is fixedly connected to it at an angle. The bottom of the filter box is connected to a drain pipe that passes through it. The drain pipe is fixedly connected to the side wall of the machine housing and extends to the outside. The end of the drain pipe is threaded with a cap, and the drain pipe is distributed to one side of the filter screen.

[0019] In the above-mentioned enameled wire surface lubrication coating machine, the bottom of the filter box and the purification box are connected to each other through a pipe located below the filter screen. The purification box has staggered partitions fixedly installed inside, and activated carbon particles are filled between the partitions. A blower is fixedly installed on the top of the purification box, and the blower is fixedly connected to an exhaust pipe. One end of the exhaust pipe is connected to the inside of the purification box, and the other end of the exhaust pipe is connected through the machine casing.

[0020] A method for lubricating and coating the surface of enameled wire involves applying lubricating oil to the surface of the enameled wire using a machine housing. Before coating, the access door is opened, and a cylinder shortens to move the sealing plate, which in turn moves the coating roller above the immersion tank. The enameled wire is then passed between the pressure rollers and into the machine housing. The wire passes through a rotating shaft and winds around the right guide wheel. The wire is then passed through two openings and wound sequentially around two coating rollers before exiting from the top of the machine housing along the left guide wheel. One end of the wire is fixed to a traction device. The cylinder then extends to press the sealing plate tightly against the immersion tank. After closing the access door with a handle, the rotating rod is rotated to limit the access door's movement. The connecting block at the bottom of the repair door is attached to one side of the opening, and one of the combination blocks, the second one, is attached to the first one to wrap the enameled wire inside, minimizing the contact between the lubricating oil in the soaking tank and the outside air. When the enameled wire is pulled, it enters the soaking tank for immersion and coating. When the enameled wire passes the clamping block, the spring pushes the scraper to scrape off the excess lubricating oil. When the excess lubricating oil drips down the enameled wire, it is collected into the soaking tank through the oil collection port formed by the first and second combination blocks. The hot air blower exhausts hot air through the air duct to dry the lubricating oil. The liquid level in the soaking tank is detected by the liquid level gauge, and the lubricating oil in the oil storage tank is transported to the soaking tank by the oil suction pump.

[0021] While the enameled wire is being conveyed, the motor drives the gears to rotate, causing the gears to rotate the rotating shaft within the fixed ring. This causes the sponge block to contact the enameled wire and scrape off surface dust. A hot air blower draws outside air into the casing, and a blower exhausts the air from inside the casing through a filter box and a purification box. Dust on the surface of the enameled wire is filtered through the filter box, and oil and gas molecules in the air are adsorbed and purified by activated carbon particles between the partitions, allowing clean air to be discharged to improve processing quality. When the casing allows air circulation, the presence of the sealing plate prevents excessive evaporation of lubricating oil and simultaneously filters and purifies oil and gas molecules in the air, thus saving lubricating oil consumption and improving air quality.

[0022] Beneficial effects:

[0023] First, this invention uses a housing to achieve surface lubrication coating treatment for enameled wire, and uses an immersion tank to achieve immersion roller coating of enameled wire. While improving the coating effect, it can also realize the lifting and lowering of the coating roller, and can be operated quickly during enameled wire traction, thereby improving production efficiency.

[0024] Secondly, the present invention is equipped with a sealing plate to seal the top of the soaking tank, thereby avoiding the problem of excessive evaporation of lubricating oil. Combined with the scraping off of excess lubricating grease, it solves the problem of lubricating oil evaporating into the processing workshop and affecting air quality.

[0025] Third, the present invention can treat the dust on the surface of the enameled wire before coating and filter the dust to prevent dust from adhering to the enameled wire and affecting the lubrication effect. At the same time, it can absorb and purify the grease in the air and discharge clean air to improve air quality. Attached Figure Description

[0053] The following are specific embodiments of the lubrication coating method for enameled wire surfaces according to the present invention.

[0054] The specific embodiment of the enameled wire surface lubrication coating method involves applying lubricating oil to the surface of the enameled wire using a housing 1. Before coating, the inspection door 24 is opened, and the sealing plate 19 is moved by the shortening of the cylinder 18, causing it to move the coating roller 23 above the immersion tank 3. The enameled wire is then passed between the pressure rollers 43 and into the housing 1. The enameled wire passes through the rotating shaft 39 and is wound around the right guide wheel 13. The enameled wire is then passed through the two openings 20 and wound around the two coating rollers 23 in sequence before exiting from the top of the housing 1 along the left guide wheel 13. One end of the enameled wire is fixed to the traction device. The cylinder 18 is then extended to make the sealing plate 19 press tightly against the immersion tank 3. After closing the inspection door 24 using the handle 27, the rotating rod 28 is rotated to align with the inspection door 24. Limiting the position, at this time, the connecting block 25 at the bottom of the inspection door 24 is engaged with one side of the opening 20, and one of the combination blocks 26 is attached to the combination block 1 21 and wraps the enameled wire inside, minimizing the contact between the lubricating oil in the soaking tank 3 and the outside air. When the enameled wire is pulled, it enters the soaking tank 3 for soaking and coating. When the enameled wire passes the clamp block 10, the spring 11 pushes the scraper 12 to scrape off the excess lubricating oil. When the excess lubricating oil drips down along the enameled wire, it is collected into the soaking tank 3 through the oil collection port formed by combination block 1 21 and combination block 2 26. The hot air blower 6 exhausts hot air through the air pipe 7 to dry the lubricating oil. The liquid level in the soaking tank 3 is detected by the liquid level gauge 17, and the lubricating oil in the oil storage tank 2 is transported to the soaking tank 3 by the oil suction pump 15.

[0055] While the enameled wire is being conveyed, the motor 41 drives the gear 42 to rotate, causing the gear 42 to drive the rotating shaft 39 to rotate within the fixed ring 38. This causes the sponge block 40 to contact the enameled wire and scrape off surface dust. The hot air blower 6 draws outside air into the housing 1, and the blower 34 discharges the air inside the housing 1 through the filter box 29 and the purification box 30. Dust on the surface of the enameled wire is filtered through the filter box 29, and oil and gas molecules in the air are adsorbed and purified by the activated carbon particles 33 between the partitions 32, allowing clean air to be discharged to improve processing quality. When the housing 1 is able to circulate air, the presence of the sealing plate 19 prevents excessive evaporation of lubricating oil and simultaneously filters and purifies oil and gas molecules in the air, thereby saving lubricating oil consumption and improving air quality.

7. A method for lubricating the surface of enameled wire using the enameled wire surface lubrication coating machine described in claim 6, characterized in that: The enameled wire is coated with lubricating oil using the housing (1). Before coating, the inspection door (24) is opened, and the sealing plate (19) is moved by the shortening of the cylinder (18), which moves the coating roller (23) above the soaking tank (3). The enameled wire is passed between the pressure rollers (43) and enters the housing (1). The enameled wire passes through the rotating shaft (39) and is wound around the right guide wheel (13). The enameled wire is passed through the two openings (20) and wound around the two coating rollers (23) in sequence. It then passes through the left guide wheel (13) and exits from the top of the housing (1). One end of the enameled wire is fixed to the traction device. The sealing plate (19) is then pressed tightly against the soaking tank (3) by the extension of the cylinder (18). The inspection door (24) is closed by the handle (27), and the rotating rod (28) is rotated to limit the inspection door (24). At this time, the inspection door (24) is closed. 24) The bottom connecting block (25) is attached to one side of the opening (20), and one of the combination blocks two (26) is attached to the combination block one (21) to wrap the enameled wire inside, so as to minimize the contact between the lubricating oil in the soaking tank (3) and the outside air. When the enameled wire is pulled, it is put into the soaking tank (3) for soaking and coating. When the enameled wire passes the clamp block (10), the spring (11) pushes the scraper (12) to scrape off the excess lubricating oil. When the excess lubricating oil drips down along the enameled wire, it is collected into the soaking tank (3) through the oil collection port composed of combination block one (21) and combination block two (26). The hot air blower (6) exhausts hot air through the air pipe (7) to dry the lubricating oil. The liquid level in the soaking tank (3) is detected by the liquid level gauge (17), and the lubricating oil in the oil storage tank (2) is transported to the soaking tank (3) by the oil suction pump (15). While the enameled wire is being transported, the motor (41) drives the gear (42) to rotate, causing the gear (42) to drive the rotating shaft (39) to rotate within the fixed ring (38), which in turn causes the sponge block (40) to contact the enameled wire to scrape off surface dust. The hot air blower (6) introduces outside air into the housing (1), and the blower (34) discharges the air inside the housing (1) through the filter box (29) and the purification box (30). The dust on the surface of the enameled wire is filtered through the filter box (29), and the oil and gas molecules in the air are adsorbed and purified by the activated carbon particles (33) between the partitions (32), so that clean air is discharged to improve the processing quality. When the housing (1) is able to circulate air, the presence of the sealing plate (19) prevents excessive evaporation of lubricating oil, while simultaneously filtering and purifying the oil and gas molecules in the air, thereby saving lubricating oil consumption and improving air quality.
