Description

Technical Field

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

[0002] Enameled wire consists of a conductor and an insulating layer. The bare wire is annealed and softened, then painted several times and baked. Painting is the process of applying a paint liquid to a metal conductor to form a uniform paint layer of a certain thickness. By forming a uniform, insulating paint film on the conductor, the conductor is protected and its electrical performance is improved. There are currently two main methods for coating conductors: the mold method and the felt method.

[0003] When coating the enameled wire, it is necessary to produce enameled wires with different paint thicknesses according to actual use needs. For example, some enameled wires require higher breakdown voltage resistance when in use, and thus the thickness of the paint needs to be increased. The existing method is to apply several layers of paint separately several times, and then lubricate and reel in the wires. Moreover, as the thickness of the coating increases, the number and time of drying and cooling will also change accordingly. Therefore, the line speed and drying temperature need to be adjusted separately for each painting operation, otherwise the overall performance of the paint layer will be affected. Therefore, when traditional enameled wire painting devices produce enameled wires with thicker paint layers, multiple painting operations not only require a lot of manpower intervention, but also make it difficult to control the production quality and have low production efficiency. Therefore, an enameled wire painting device is needed to solve the above problems. Summary of the invention

[0027] A notch is provided at the bottom of the cooling chamber on a side away from the drying chamber, and the notch is located on the moving path of the third guide wheel.

[0028] The technical solution of the embodiment of the present invention has at least the following advantages and beneficial effects:

[0029] 1. The metal wires are wound on N groups of conductor racks in sequence, and the metal wires are distributed in a spiral shape. Due to different wire diameters or different performance requirements, the number of times the metal wires need to be painted is determined, and then the m conductor racks are pushed back, so that the metal wires between the m groups of first guide wheels and the third guide wheels enter the painting room, the drying room and the cooling room through the wire groove. Then, the metal wires are successively painted, dried and cooled for multiple times during the continuous transportation process. Compared with the traditional painting in batches, the painting efficiency is greatly improved, and the probability of the metal wires being worn by external forces in the traditional batch operation is also avoided.

[0030] 2. When the first group of wire racks moves backward a certain distance, the first group of driving sleeves abuts against the first group of cylinders, and then continues to drive the first group of wire racks to move backward into position, so that the metal between the first guide wheel and the third guide wheel above it enters the painting room and the drying room. At the same time, the driving frame is driven by the driving rod to move backward, and the driving frame drives the driving shaft to rotate 1 / N azimuth angle through the driving gear, worm and turbine in turn. At the same time, the first group of incomplete gears cooperates with the corresponding rack through the driven gear to drive the first group of first felts to move downward, so as to realize the painting operation of the metal wire on the first group of wire racks, as well as drying and cooling. When the metal wire is transported to the first guide wheel of the second group of wire racks, if it needs to be painted, The second group of driving frames can be driven to move backwards so that the metal wire between the first guide wheel and the third guide wheel above them enters the painting room. At the same time, the second group of driving sleeves on the second group of wire racks drives the second group of cylinders to move backwards. Like the first group, the second group of first felts and second felts clamp the metal wire between the first guide wheel and the third guide wheel on the second group of wire racks for the second painting. This reciprocating process can be used to drive several groups of wire racks according to the number of times paint is applied, usually up to eight times. The overall number of coatings can be controlled at will, which is convenient to adjust and the painting operation is reliable. When all N groups do not need to be coated, it is also possible not to wind N groups of wire racks. When several coatings are required, the metal wire can be wound around several groups of wire racks.

[0031] 3. Whether each group of wire racks needs to be painted and dried can be controlled according to the coating requirements of the enameled wire. For some thicker or multi-coated enameled wires, a longer drying or cooling time may be required after coating several times. The first guide member located on the same wire rack can be moved to the right by the first push cylinder. If it is moved to the painting room and the drying room, the drying and cooling can be increased. If it is moved to the cooling room, the cooling time can be increased. The drying and cooling time can be controlled according to the actual production needs of the enameled wire to ensure that the curing effect of the paint liquid on the enameled wire meets the standards.

[0032] 4. The height of the first guide wheel and the third guide wheel are controlled by the second push cylinder and the third push cylinder, and the first guide wheel can be flexibly controlled in cooperation with the first push cylinder. The position of the second guide wheel and the third guide wheel, and then the enameled wire, after being coated several times, does not need to be painted, dried and cooled, but only used for observation or at room temperature, can be controlled by the second push cylinder and the third push cylinder to move down to the bottom of the painting room and the drying room, so that when the wire rack moves backward, the metal wire on the first guide wheel and the second guide wheel will not enter the wire groove, and will not affect the subsequent wire rack to continue to guide the metal wire into the painting room.

[0033] 5. Since the metal wire of the fourth guide wheel on the previous wire rack is transported to the second guide wheel on the next wire rack, and since there is a distance between adjacent wire racks, the fourth guide wheel and the second guide wheel can be deflected to a certain direction to facilitate the guiding of the metal wire and avoid wear of the painted metal wire.

[0046] N groups of wire racks 7 are slidably arranged along the front-back direction below the drying chamber 4, and the left and right ends of the wire rack 7 are respectively provided with a first guide member 71 and a second guide member 72, the painting chamber 3 and the drying chamber 4 are located between the first guide member 71 and the second guide member 72, and the upper and lower ends of the first guide member 71 are respectively provided with a first guide wheel 73 and a second guide wheel 74, and the upper and lower ends of the second guide member 72 are respectively provided with a third guide wheel 75 and a fourth guide wheel 76;

[0047] More specifically, Figure 1-3 As shown, after the metal wire 1 comes out from the pay-off roller, it is sequentially wound around the first guide wheel 73, the third guide wheel 75 and the fourth guide wheel 76 on the first group of conductor racks 7, and then around the second guide wheel 74 on the second group of conductor racks 7, and then upwardly wound around the first guide wheel 73, the third guide wheel 75 and the fourth guide wheel 76 on the second group of conductor racks 7, and wound around the remaining N-2 groups of conductor racks 7 in this winding manner, and the metal wire 1 is led out to the take-up roller through the second guide wheel 74 located on the last group of conductor racks 7;

[0048] like Figure 1 As shown, the portion of the metal wire 1 between the first guide wheel 73 and the third guide wheel 75 is located at the same horizontal plane as the wire passage 6 .

[0049] During specific implementation, the metal wire 1 is wound on N groups of conductor racks 7 in sequence, and the metal wire 1 is distributed in a spiral shape. Due to different wire diameters or different performance requirements, the number of times m that the metal wire 1 needs to be painted is determined, and then the m conductor racks 7 are pushed backward, so that the metal wire 1 between the m groups of first guide wheels 73 and third guide wheels 75 enters the painting chamber 3, the drying chamber 4 and the cooling chamber 5 through the wire groove 6, and then the metal wire 1 is repeatedly subjected to painting, drying and cooling during the continuous transportation process. Compared with the traditional painting in batches, the painting operation efficiency is greatly improved, and the probability of the traditional metal wire 1 being worn by external forces in the traditional batch operation is also avoided.

[0050] like Figure 1 , 2 As shown in 4-6, a paint pool 31 is provided at the bottom of the paint room 3, and paint liquid is provided in the paint pool 31. N groups of paint parts 32 are arranged above the paint pool 31 at intervals along the front-to-back direction. The paint parts 32 include a first felt 321 arranged for vertical sliding and a second felt 322 arranged in the paint pool 31, and the second felt 322 is located below the first felt 321;

[0051] A U-shaped groove opening downward is provided at the bottom of the first felt 321 along the left-right direction. When the metal wire 1 enters the paint chamber 3 through the translation of the wire rack 7 and is located on the top of the corresponding second felt 322, the first felt 321 is moved down into the paint pool 31, so that the metal wire 1 enters the U-shaped groove 323 and slides between the second felt 322 and the first felt 321, and then the metal wire 1 is painted by the first felt 321 and the second felt 322, so that it is evenly stained with paint liquid and enters the drying chamber 4.

[0052] A driving shaft 33 is provided in the painting room 3 to rotate in the front-to-back direction. The painting member 32 further comprises an incomplete gear 324, a driven gear 325 and a driving seat 326. N groups of incomplete gears 324 are sleeved on the driving shaft 33 at intervals.

[0055] like Figure 1-6 As shown, in a specific implementation, after the metal wire 1 of the m-group wire rack 7 enters the paint chamber 3, the driving shaft is controlled to rotate m / N positions, and then the m-group incomplete gear 324 first drives the m-group driven gear 325 to rotate, and the m-group driven gear 325 first drives the rack 327 on the m-group driving seat 326 to move downward, and then respectively drives the U-shaped groove 323 and the second felt 322 of the m-group first felt 321 to cooperate to clamp the metal wire 1 located inside thereof, so as to facilitate the painting operation, and clamp the metal wire 1 in turn, which will not affect the metal wire 1 located at the rear when entering the paint chamber 3. On the contrary, when the first felt 321 releases the metal wire 1, the one located on the front side of the frame 2 is released first, and after its wire rack 7 moves forward and out of the paint chamber 3, the next first felt 321 releases the corresponding metal wire 1.

[0064] More specifically, a plurality of guide rods 77 are slidably arranged on the wire rack 7 in the left-right direction, and one end of the plurality of guide rods 77 is connected to the first guide member 71;

[0065] A first push cylinder 78 is horizontally arranged on the wire rack 7 , and a telescopic end of the first push rod is connected to the first guide member 71 .

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
