Description

Technical Field

[0001] The invention relates to the technical field of enameled wire production equipment, and in particular to an enameled wire surface lubricating liquid coating device. Background Art

[0002] During the production process, the enameled wire is coated with lubricating liquid on its surface to prevent the surface of the enameled wire from being mechanically damaged during the process of paying off or taking up the enameled wire, and to improve the smoothness of paying off and taking up the enameled wire. The viscosity of the lubricating liquid used for lubricating the surface of the enameled wire is usually 200-250cst at 40°C. When the enameled wire is coated with lubricating liquid, due to the relatively poor uniformity of the coated lubricating liquid, when there is more lubricating liquid coated on a certain part of the surface of the enameled wire, it will drip under the action of gravity, causing waste of lubricating liquid, and it will also make it difficult to predict the timing of the excess lubricating liquid dripping on the enameled wire, and the lubricating liquid will drip on the subsequent conveying path of the enameled wire, increasing the workload of subsequent cleaning.

[0003] In order to solve the above technical problems, the existing patent application No. 202311252033.0 discloses a coating and coating method of enameled wire lubricant. The device adopts an adjustable upper and lower pressure plates arranged relatively up and down, and coating blocks are arranged on the opposite surfaces of the upper and lower pressure plates. The spacing between the two relative coating blocks can be adjusted so that the lubricant pumped between the coating blocks by the pump body can be evenly coated on the surface of the enameled wire, thereby improving the coating uniformity of the lubricant, and allowing excess lubricant to fall to the top of the partition and flow back through the guide pipe at the center of the partition to achieve the circulation of the lubricant and avoid excess lubricant being carried to the outside of the box. However, since the lubricant used in the enameled wire is a high-grade viscosity index lubricant, its fluidity is poor. As the lubricant coating time increases, the lubricant is easily blocked at the top of the partition, which has a greater impact on the circulation efficiency of the lubricant. Summary of the invention

[0004] In view of this, the purpose of the present invention is to propose an enameled wire surface lubricant coating device to solve the problem that as the lubricant coating time increases, the lubricant is easily blocked on the top of the partition and has a significant impact on the circulation efficiency of the lubricant.

[0019] The residual liquid scraper disposed between the line inlet and the line outlet is rotated.

[0020] A scraper strip is transversely fixed in the line inlet, and one end of the scraper strip is inserted into the residual liquid scraper bucket and overlapped on the inner wall of the residual liquid scraper bucket.

[0021] A telescopic cylinder is arranged on the top of the threading box.

[0043] like Figures 1 to 4 As shown, a lubricating liquid coating device for the surface of an enameled wire comprises a lubricating liquid supply box 1 for containing lubricating liquid, and the lubricating liquid coating device for the surface of an enameled wire further comprises:

[0044] The lubricating liquid coating mechanism 2 is arranged at the top of the lubricating liquid supply box 1, and is used to evenly coat the lubricating liquid on the surface of the enameled wire passing through the inside thereof and remove the lubricating liquid dripping on the surface of the enameled wire.

[0045] The supply part 3 is arranged between the lubricating liquid supply tank 1 and the lubricating liquid coating mechanism 2. The supply part 3 includes a supply pump arranged in the lubricating liquid supply tank 1 and a supply pipe arranged between the output end of the supply pump and the inside of the liquid separator box 24. The supply part 3 is used to continuously supply the lubricating liquid contained in the lubricating liquid supply tank 1 to the lubricating liquid coating mechanism 2.

[0046] like Figures 2 to 4 As shown, the lubricating liquid coating mechanism 2 includes:

[0047] A bottomless box 21 is fixedly arranged on the top of the lubricating liquid supply tank 1 .

[0048] A plurality of coating boxes 25 are fixed in parallel on the top of the bottomless box 21 , a wire inlet hole 22 is provided between the inside of the coating box 25 and one of the vertical surfaces of the bottomless box 21 , and a wire outlet hole 27 is provided on the vertical surface of the coating box 25 away from the wire inlet hole 22 .

[0049] A liquid separation box 24 is fixedly arranged on the top of the bottomless box 21 , and a plurality of liquid outlet holes 26 are arranged in parallel at the bottom of the liquid separation box 24 .

[0050] A plurality of sealing rubber strips 23 are circumferentially fixedly arranged in the wire inlet hole 22 . The sealing rubber strips 23 are used to seal the gap between the wire inlet hole 22 and the enameled wire when the enameled wire crosses the wire inlet hole 22 .

[0051] The wire inlet hole 22 and the wire outlet hole 27 are coaxial in the transverse direction, and the wire inlet hole 22 and the wire outlet hole 27 are respectively located on two relatively vertical surfaces of the coating box 25.

[0052] The liquid outlet 26 corresponds to the coating box 25 , and the liquid outlet 26 is used to transport the lubricating liquid continuously supplied by the supply part 3 into the coating box 25 .

[0053] With such a design, when the enameled wire is continuously conveyed, the lubricating liquid can be continuously added to the coating box 25 through the supply part 3, so that the interior of the coating box is always in a saturated state, so that when the enameled wire passes through the coating box 25, the lubricating liquid can be fully attached to the surface of the enameled wire, completing the initial coating operation of the lubricating liquid and avoiding omissions in the coating of the lubricating liquid.

[0054] like Figures 2 to 7 As shown, the lubricating liquid coating mechanism 2 also includes:

[0055] An embedded groove 28 is provided on the bottomless box 21, and a residual liquid cleaning portion 29 is provided in the embedded groove 28. The residual liquid cleaning portion 29 is used to clean the excess lubricating liquid on the enameled wire and spread the lubricating liquid on the enameled wire evenly.

[0056] The residual liquid removal unit 29 includes:

[0057] A wire threading box 291 is vertically inserted into the embedded groove 28 , and a plurality of wire inlets 292 are arranged in parallel on one vertical surface of the wire threading box 291 , and a plurality of wire outlets 293 are arranged in parallel on a vertical surface of the wire threading box 291 away from the wire inlets 292 .

[0058] The residual liquid scraper 294 disposed between the line inlet 292 and the line outlet 293 is rotated.

[0059] A scraper strip 295 is transversely fixed in the line inlet 292 , and one end of the scraper strip 295 is inserted into the residual liquid scraper bucket 294 and overlapped on the inner wall of the residual liquid scraper bucket 294 .

[0060] A telescopic cylinder 297 is provided on the top of the threading box 291 .

[0061] The transmission member 296 is used to link the output end of the telescopic cylinder 297 and a plurality of residual liquid scrapers 294. The transmission member 296 includes a transmission tooth 2961 rotatably arranged in the threading box 291 and a gear ring 2962 fixedly sleeved on the outside of the residual liquid scraper 294. The threading box 291 is rotatably provided with a double gear rod 2963 inside and on the top. A second belt 2965 is sleeved between the two double gear rods 2963. A rack is slidably provided between the double gear rod 2963 located at the top of the threading box 291 and the top of the threading box 291. 2966, one end of the rack 2966 is fixed on the output end of the telescopic cylinder 297, and a first batch of belts 2964 are sleeved between the transmission gear 2961, the double-toothed rod 2963 located inside the threading box 291, and a plurality of toothed rings 2962, so that by controlling the reciprocating extension and retraction of the output end of the telescopic cylinder 297, a plurality of residual liquid scrapers 294 can be synchronously driven to rotate back and forth alternately, so that the accumulated lubricating liquid inside the plurality of residual liquid scrapers 294 can be synchronously scraped off, thereby improving the efficiency of the lubricating liquid reflux.

[0062] like Figure 4 As shown, the wire box 291 is located in the bottomless box 21 near the wire outlet hole 27, and the wire box 291 is bottomless. This design makes it easy to quickly find the fault point and facilitate maintenance when the transmission member 296 fails.

[0063] like Figures 1 to 4 As shown, the inner diameter of the outlet 293 is smaller than that of the inlet 292 , and the inner diameters of the outlet 293 and the inlet 292 are respectively equal to the inner diameters of both ends of the residual liquid scraper 294 .

[0064] The wire inlet 292 and the wire outlet 293 are coaxial in the transverse direction, and the wire inlet 292 is coaxial with the wire outlet hole 27 in the transverse direction.

[0065] Such a design makes it easy to thread the enameled wire along the axis when threading the enameled wire, so that the enameled wire can be coaxial with the wire inlet hole 22, the wire outlet hole 27, the wire inlet port 292, the residual liquid scraper 294 and the wire outlet 293 at the same time. In this way, when the enameled wire passes out of the coating box 25 and enters the residual liquid scraper 294, the residual liquid scraper 294 is designed to gradually reduce the inner diameter of the residual liquid scraper 294 along the enameled wire conveying direction, so that the excess lubricating liquid coated on the surface of the enameled wire can be scraped off in a centralized manner, and the enameled wire can be completely The lubricating liquid on the surface of the enameled wire is evenly smoothed in all directions to improve the uniformity of the lubricating liquid coating. The telescopic cylinder 297 and the transmission member 296 can be used in conjunction to synchronously drive a plurality of residual liquid scrapers 294 to rotate back and forth alternately, so that the scraper bar 295 can drop the lubricating liquid in the residual liquid scraper 294 into the lubricating liquid supply box 1 to prevent the lubricating liquid from accumulating too much in the residual liquid scraper 294 and being squeezed out from the wire outlet 293, thereby affecting the uniformity of the lubricating liquid coating.

[0066] Working principle: First, start the supply pump to continuously add lubricating liquid into the coating box until the lubricating liquid is full. The excess lubricating liquid will flow out directly from the outlet hole 27 and directly fall into the lubricating liquid supply box 1 to avoid excessive accumulation of lubricating liquid in other components, which will cause blockage and retention and affect the circulation efficiency of the lubricating liquid. Then, the enameled wire will pass through the inlet hole 22, the coating box 25, the outlet hole 27, the inlet port 292, the residual liquid scraper 294 and the outlet port 293 in a horizontal straight line in sequence, and the enameled wire and the inlet hole 22, the outlet hole 27, the inlet port 292, the residual liquid scraper 294 and the outlet port 293 are connected. The hole 27, the wire inlet 292, the residual liquid scraper 294 and the wire outlet 293 are in a coaxial relationship. The sealing rubber strip 23 in the wire inlet hole 22 undergoes elastic deformation and fits tightly to the surface of the enameled wire to prevent the lubricant from flowing out of the wire inlet hole 22. When the enameled wire passes through the coating box 25 filled with lubricant, the lubricant will fully adhere to the surface of the enameled wire, and excess lubricant will be brought out by the enameled wire in a linear conveying state. The excess lubricant on the enameled wire will drip into the lubricant supply box 1 under the action of gravity. The inner diameter of the residual liquid scraper 294 gradually decreases along the conveying direction of the enameled wire. The residual liquid scraper 294 with a gradually decreasing inner diameter evenly scrapes away the excess lubricant on the surface of the enameled wire, and can simultaneously and comprehensively smooth the lubricant on the surface of the enameled wire, thereby improving the uniformity of the lubricant coating. At the same time, the output end of the telescopic cylinder 297 is controlled to reciprocate and telescopically move at a fixed distance, and the power is synchronously transmitted to a plurality of residual liquid scrapers 294 through the transmission member 296, so that the positive and negative rotations are alternately performed, so that the inner wall of the residual liquid scraper 294 and the scraper strip 295 are aligned with each other. Relative movement is formed between them, so that the scraper bar 295 scrapes off the lubricating liquid gathered in the residual liquid scraper 294, and makes the lubricating liquid fall directly into the lubricating liquid supply box 1, thereby improving the efficiency of the circulation of the lubricating liquid, and when the diameter of the enameled wire is changed, the residual liquid cleaning part 29 can be easily removed from the embedded groove 28 by pulling up, and then the residual liquid cleaning part 29 with an inner diameter of the outlet 293 matching the diameter of the replaced enameled wire can be inserted into the embedded groove 28, so that the synchronous replacement of the residual liquid cleaning part 29 can be completed, and the operation is simple and efficient.
