Description

Technical Field

[0001] This invention relates to the field of Leeds wire production technology, specifically to a surface oiling device for Leeds wire production. Background Technology

[0002] Litz wire is a type of wire specifically designed for high-frequency applications. It consists of multiple strands of fine insulated wires twisted together, with each wire individually wrapped in insulation. This effectively reduces energy loss caused by the skin effect and proximity effect, which can lead to increased resistance and reduced efficiency when high-frequency current passes through ordinary cables.

[0003] During the manufacturing process, Litz wire is made of multiple strands of fine insulated wires twisted together. These fine wires need to pass through various mechanical devices, such as guide wheels and wire drawing dies, during twisting and subsequent processing. Oiling can effectively reduce the friction between the wires and the mechanical equipment, preventing damage or wear to the wire surface. Moreover, copper or other metal materials are prone to oxidation in the air, especially in high temperature or humid environments, which can affect conductivity and shorten the product's service life. Surface oiling forms a protective film that isolates oxygen and moisture in the air, thereby preventing oxidation of the metal surface.

[0004] Chinese Patent 202321799656.5 discloses a surface oiling device for Leeds wire production. This application, by incorporating an oil tank and rotating rollers, allows the wire to pass through the inlet and exit the outlet for winding. During this process, the wire is immersed in anti-corrosion oil by the bottom surface of the rotating rollers. Additionally, a receiving box is included to collect dripping anti-corrosion oil from the surface of the wound wire. This device facilitates the application of anti-corrosion oil, minimizes manual operation, and improves oiling efficiency. However, this application shares the following shortcomings with existing oiling devices on the market:

[0005] The aforementioned application describes how the Litz wire is immersed in anti-corrosion oil in an oil tank using rotating rollers. This immersion method cannot guarantee the uniformity of the oil coating on the surface of the Litz wire. Because the Litz wire is immersed in oil, some areas may experience uneven oil coating due to the viscosity and fluidity of the oil, resulting in some parts having an excessively thick oil layer while other parts may have an excessively thin oil layer or not be completely covered. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a surface oiling device for the production of Litz wire, which has advantages such as uniform oiling and solves the problem of uneven oiling caused by the Litz wire being immersed in an oil tank by rotating rollers.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a surface oiling device for production on the Leeds line, comprising two support columns, an oiling tank, and a collection tank. The two support columns are vertically fixed on the left and right sides between opposite sides of the oiling tank and the collection tank, and the oiling tank and the collection tank are horizontally distributed vertically via the support columns.

[0024] Furthermore, two mounting plates are fixed on opposite sides of each of the two mounting plates, and the two hollow rods on the right side are rotatably connected to the mounting plates on both sides via bearings. The ends of the four connecting pipes away from the hollow rods all penetrate and extend to the outside of the oiling tank.

[0025] Furthermore, the two mounting plates are symmetrically distributed inside the oiling box, and the four hollow rods are all set with one end open and the other end closed.

[0026] Furthermore, the upper surface of the mounting plate is raised, and the center of the annular tube is coaxially arranged with the center line of the oiling box and located between the four atomizing nozzles.

[0027] Furthermore, the recycling mechanism includes a guide plate, a drip pipe, two inclined pipes, two filter boxes, four placement plates, two filter screens, a delivery pump, a three-way pipe B, and a return pipe.

[0028] The guide plate is fixed to the inner top wall of the collection box. The drip pipe is connected and fixed to the center of the lower surface of the guide plate. The two inclined pipes are fixed to the left and right sides of the drip pipe, respectively. The four placement plates are arranged in pairs and fixed to the inner walls of the left and right sides of the two filter boxes. The two filter boxes are placed on the left and right sides of the bottom wall of the collection box. The two filter screens are placed on the upper side of the two sets of placement plates. The delivery pump is fixed to the front of the collection box and its inlet end is connected and fixed to the three-way pipe B.

[0030] Furthermore, the angle between the two inclined tubes and the horizontal plane is 30 degrees, and they face the two filter boxes respectively. The cross-sectional shape of the guide plate is V-shaped.

[0031] Furthermore, the back of the collection box is missing to form a rectangular opening, and a maintenance door is hinged inside the opening. Both filter boxes are hollow cuboids with missing upper surfaces.

[0032] Furthermore, the bottom ends of the three oil drain pipes all penetrate and extend into the collection box and face the direction of the guide plate, and the length of the filter box is less than half the length of the inner cavity of the collection box.

[0033] Furthermore, a filter screen is fixed at the air inlet of the fan, and openings allowing Litz lines to pass through are provided at the center of both the left and right sides of the oiling box. The length and width of the oiling box are smaller than the length and width of the collection box.

[0034] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0035] 1. This surface oiling equipment for Litz wire production uses multiple atomizing nozzles to atomize lubricating oil and spray it evenly onto the surface of the Litz wire. The lubricating oil is further evenly coated by horizontally and vertically rotating airbags, ensuring comprehensive and uniform oiling. This not only improves oiling efficiency but also enhances the adhesion of the lubricating oil through the synergistic effect of the fan and airbags. This effectively reduces surface damage and wear on the wires caused by uneven oiling and avoids the problem of conductivity being affected by excessively thick or thin oil layers.

[0036] 2. This surface oiling equipment for the Leeds production line features a recovery mechanism that effectively guides and filters dripping oil through components such as guide plates, drip pipes, inclined pipes, and filter boxes, resulting in recycling and significantly improving oil recovery and utilization rates.

Detailed Implementation

[0042] 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.

[0043] Please see Figure 1-4 This embodiment of a surface oiling device for Leeds line production includes two support columns 1, an oiling tank 2 and a collection tank 3. The two support columns 1 are vertically fixed on the left and right sides between opposite sides of the oiling tank 2 and the collection tank 3, and the oiling tank 2 and the collection tank 3 are horizontally distributed vertically via the support columns 1. The oiling tank 2 is equipped with an oiling mechanism 20 for oiling the surface of the Leeds line, and the collection tank 3 is equipped with a recycling mechanism 5 for recycling the fallen oil droplets.

[0044] The oiling mechanism 20 includes the following:

[0045] Multiple lifting rods 200: They are divided into two groups, and the two groups of lifting rods 200 are respectively fixed to the upper and lower inner walls of the oiling tank 2;

[0046] Two mounting plates 201: Both are horizontally set and are vertically fixed to one end of each of the two sets of hangers 200;

[0047] Four hollow rods 202: They are arranged in pairs, with the two hollow rods 202 on the left being vertically connected to the opposite side of the two mounting plates 201 via bearings and close to the left side of the mounting plate 201; and the two hollow rods 202 on the right being horizontally connected to the two mounting plates 201 via bearings.

[0048] Multiple air holes 203: These are respectively opened on the outer side of the four hollow rods 202;

[0049] Four airbags 204: They are respectively connected and fixed to the outside of four hollow rods 202;

[0050] Four connecting pipes 205: They are rotatably connected to the openings of four hollow rods 202 respectively through sealed bearings;

[0051] Side pipes 206: They are fixed to the upper and lower sides of the oiling tank 2 respectively, and each side pipe 206 is connected and fixed to two connecting pipes 205;

[0052] Two exhaust valves 207: They are respectively sleeved on the outside of the two side pipes 206;

[0053] A blower 208: It is fixed to the front of the oiling tank 2;

[0054] A three-way pipe A209: one end of which is fixed to the air outlet of the fan 208, and the other two ends are connected and fixed to the two side pipes 206;

[0055] Three rows of oil pipes 210: They are uniformly and fixedly connected between the oiling tank 2 and the collection tank 3 on opposite sides;

[0056] Four support rods 211: They are respectively fixed to the four inner walls of the oiling tank 2;

[0057] A ring tube 212: which is fixed to the other end of the four support rods 211;

[0058] Four atomizing nozzles 213: They are all fixed inside the annular tube 212 and correspond to the four support rods 211 respectively.

[0059] It should be noted that the oiling mechanism 20 achieves efficient and uniform coating of lubricating oil through the coordinated operation of multiple meticulously designed components. Multiple hangers 200 and two mounting plates 201 form a stable support structure, ensuring the stability of the entire mechanism. Four hollow rods 202, in conjunction with multiple air holes 203 and four air bladders 204, utilize airflow introduced by the fan 208 and the three-way pipe A209 to achieve the expansion and rotation of the air bladders 204, driving the lubricating oil to distribute evenly. Simultaneously, four connecting pipes 205, two side pipes 206, and two exhaust valves 207 precisely control the airflow direction, further optimizing the oiling effect. Three oil pipes 210 ensure a stable supply of lubricating oil, while four support rods 211, one annular pipe 212, and four atomizing nozzles 213 ensure that the lubricating oil is precisely sprayed onto the Litz line surface in an atomized form, comprehensively improving the uniformity and efficiency of oiling.

[0060] Two mounting plates are fixed on opposite sides of the two mounting plates 201. The two hollow rods 202 on the right side are rotatably connected to the mounting plates on both sides through bearings. The ends of the four connecting pipes 205 away from the hollow rods 202 all pass through and extend to the outside of the oiling tank 2.

[0061] It should be noted that the flexible rotation of the hollow rod 202 is achieved through the cooperation of the mounting plate and bearing, enhancing the stability and reliability of the oiling mechanism 20. Simultaneously, the connecting pipe 205 extends to the outside of the oiling tank 2, ensuring smooth transmission of lubricating oil or airflow and improving the uniformity and efficiency of oiling.

[0062] Among them, the two mounting plates 201 are located inside the oiling box 2 and are symmetrically distributed vertically, and the four hollow rods 202 are all set with one end open and the other end closed.

[0063] It should be noted that the symmetrically distributed mounting plates 201 provide stable support for the oiling mechanism 20. The hollow rod 202, with one end open and the other closed, ensures the smooth passage of lubricating oil or gas while enhancing structural stability, thus contributing to uniform distribution and efficient coating of lubricating oil.

[0064] The upper surface of the mounting plate 201 is raised, and the center of the annular tube 212 is coaxially arranged with the center line of the oiling box 2 and located between the four atomizing nozzles 213.

[0065] It should be noted that the raised design on the upper surface of the mounting plate 201 helps to better support and fix other components, enhancing the stability of the entire oiling mechanism 20. The coaxial arrangement of the annular tube 212 with the center line of the oiling tank 2, and its position among the four atomizing nozzles 213, ensures that the lubricating oil can be evenly sprayed onto the Litz line surface through the atomizing nozzles 213, thereby achieving a more uniform oiling effect and improving the oiling quality.

[0066] The recycling mechanism 5 includes a guide plate 501, an oil dripping pipe 502, two inclined pipes 503, two filter boxes 504, four placement plates 505, two filter screens 506, a delivery pump 507, a three-way pipe B 508, and a return pipe 509.

[0067] The guide plate 501 is fixed to the inner top wall of the collection box 3. The drip pipe 502 is connected and fixed to the center of the lower surface of the guide plate 501. The two inclined pipes 503 are fixed to the left and right sides of the drip pipe 502 respectively. The four placement plates 505 are arranged in pairs and fixed to the inner walls of the left and right sides of the two filter boxes 504 respectively. The two filter boxes 504 are placed on the left and right sides of the bottom wall of the collection box 3 respectively. The two filter screens 506 are placed on the upper side of the two sets of placement plates 505 respectively. The delivery pump 507 is fixed to the front of the collection box 3 and its inlet end is connected and fixed to the three-way pipe B508. The other two ends of the three-way pipe B508 are both inserted and extended into the interior of the collection box 3 and are connected and fixed to the two filter boxes 504 respectively.

[0068] It should be noted that the recycling mechanism 5, through the coordinated operation of multiple carefully designed components, achieves effective collection, filtration, and recycling of fallen oil droplets. The combination of the guide plate 501 and the drip pipe 502 ensures that the oil droplets can smoothly converge and flow to the filtration system. Two inclined pipes 503 further guide the oil flow to the filter boxes 504 on both sides; this diversion design improves filtration efficiency. Four placement plates 505 provide stable support for the filter screen 506, which is responsible for removing impurities from the oil, ensuring its purity. The installation of the transfer pump 507 and the three-way pipe B508 allows the filtered oil to be effectively transported back to the oiling system, realizing oil recycling, thereby improving resource utilization, reducing production costs, and also reducing the environmental impact caused by oil waste.

[0069] The annular pipe 212 is connected and fixed to one end of the return pipe 509, and the other end of the return pipe 509 is connected and fixed to the liquid outlet of the delivery pump 507. The recovery mechanism 5 also includes control valves respectively sleeved on the outside of the two inclined pipes 503.

[0070] It should be noted that the connection and fixation between the annular pipe 212 and the return pipe 509, as well as the connection between the return pipe 509 and the outlet end of the delivery pump 507, enables efficient recycling of the filtered oil, ensuring a continuous and stable supply of lubricating oil to the oiling mechanism 20 and maintaining the smooth operation of the entire oiling system. Furthermore, the control valve outside the inclined pipe 503 in the recovery mechanism 5 provides a flexible means of controlling the oil flow direction, allowing maintenance of the filtration system without shutting down the machine, such as cleaning or replacing clogged filter screens 506. This ensures continuous and stable operation of the equipment, further improving production efficiency and equipment reliability.

[0071] The two inclined tubes 503 are at an angle of 30 degrees to the horizontal plane and face the two filter boxes 504 respectively. The cross-sectional shape of the guide plate 501 is V-shaped. The back part of the collection box 3 is missing to form a rectangular opening, and the inside of the opening is hinged with a maintenance door. The two filter boxes 504 are both hollow cuboids with missing upper surfaces.

[0072] It should be noted that the two inclined pipes 503 are at a 30-degree angle to the horizontal plane and face the filter box 504, which helps the oil flow smoothly into the filter box 504 and improves the oil recovery efficiency. The V-shaped cross-section of the guide plate 501 can effectively collect the dripping oil droplets, directing them to the drip pipe 502, further optimizing the oil collection process. The rectangular opening and maintenance door design on the back of the collection box 3 facilitates maintenance and cleaning of the filter box 504 by operators, improving the maintainability of the equipment. The cuboid structure of the filter box 504, with a missing upper surface, facilitates the installation and replacement of the filter screen 506, and also facilitates the filtration and collection of oil. These design details collectively enhance the performance and operational convenience of the entire recovery mechanism 5.

[0073] Among them, the bottom ends of the three oil drain pipes 210 all penetrate and extend into the collection box 3 and face the direction of the guide plate 501. The length of the filter box 504 is less than half the length of the inner cavity of the collection box 3. The air inlet end of the blower 208 is fixed with a filter screen 4. The center of the left and right sides of the oiling box 2 is provided with a box opening that allows the Litz line to pass through. The length and width of the oiling box 2 are both less than the length and width of the collection box 3.

[0074] It should be noted that the bottom ends of the three oil drain pipes 210 extend into the collection box 3 and face the guide plate 501. This layout ensures that the oil dripping during the oiling process can flow directly to the guide plate 501, and then be effectively collected and guided to the recovery mechanism 5, improving the efficiency and accuracy of oil recovery. The length of the filter box 504 is less than half the length of the inner cavity of the collection box 3, providing ample space for oil flow and filtration operations. It also facilitates the installation, maintenance, and cleaning of the filter box 504, ensuring efficient filtration. A filter screen 4 is fixed at the air inlet of the blower 208, which can effectively filter the air entering the blower, preventing dust and other impurities from entering the oiling system, thereby ensuring the purity of the lubricating oil, improving the oiling quality, and extending the service life of the equipment.

[0075] The working principle of the above embodiment is as follows: The Litz wire enters the oiling tank 2 from the right side and passes through the annular pipe 212. Under the action of the delivery pump 507, the lubricating oil in the return pipe 509 enters the annular pipe 212. The lubricating oil in the annular pipe 212 is atomized into fine oil droplets by four atomizing nozzles 213 and comes into uniform contact with the surface of the Litz wire. The atomized lubricating oil is evenly sprayed on the surface of the Litz wire. At the same time, the airflow generated by the fan 208 enters the four hollow rods 202 through the three-way pipe A209 and the side pipe 206. The airflow from the hollow rods 202... The air vents 203 discharge, causing the airbags 204 to inflate. The expansion size allows for auxiliary oiling of Litz wires of varying thicknesses, and ensures more even oil distribution after full contact with the wire surface. The two airbags 204 on the left rotate vertically, while the two on the right rotate horizontally. The rotating airbags 204 drive the surrounding airflow, further evenly coating the Litz wire surface with lubricant. Oil dripping from the Litz wire surface and oil droplets in the air of the oiling tank 2 flow through the drain pipe 210 onto the guide plate 501. The V-shaped cross-section of the flow plate 501 causes the oil to converge towards the center along the inclined plane. The converged oil then flows through the drip pipe 502 into two inclined pipes 503 at a 30-degree angle to the horizontal plane, facing the two filter boxes 504 respectively, guiding the oil to the filter boxes 504. The oil then flows through the inclined pipes 503 into the filter screen 506 inside the filter box 504. The filter screen 506 filters the oil, removing impurities and particles. The filtered oil flows into the bottom of the filter box 504, and the delivery pump 507 draws the filtered oil from the two filter boxes 504 through the three-way pipe B508. The extracted oil is transported back to the annular pipe 212 of the oil tank 2 through the return pipe 509, realizing the recycling of the oil. When the filter screen 506 is clogged, the oil flow direction can be switched by the control valve so that the oil passes through only one filter box 504. The clogged filter screen 506 can be cleaned or replaced without stopping the machine, ensuring the continuous and stable operation of the equipment. The maintenance door on the back of the collection box 3 can be opened to facilitate the maintenance of the filter box 504. The filter box 504 is a rectangular prism with a hollow interior and a missing upper surface, which makes it easy to remove and replace the filter screen 506.
