Description

Technical Field

[0001] The utility model relates to an energy-saving and environment-friendly high-speed flat wire enameling machine, belonging to the technical field of enameled flat wire production. Background Art

[0002] For the current production process of horizontal enameling machines, please refer to the attached Figure 1 The traditional flat wire enameling machine in the background technology includes a traveling guide wheel group 1, a painting mechanism, a drying furnace body, a wire running box body 1, a traveling guide wheel group 2, a wire running box body 2 and a wire guide wheel. After the flat wire enters the painting mechanism for painting, it enters the drying furnace body for baking, and then enters the wire running box body 1 and turns through the traveling guide wheel group 2 to enter the wire running box body 2. After passing through, it is painted again by the traveling guide wheel group 1. After the flat wire is painted on one side of the drying furnace body, it enters the drying furnace body for baking. After the paint film is evaporated and solidified, it is cooled by natural wind in the wire running box body after leaving the drying furnace body. After the traveling guide wheel group 1 and the traveling guide wheel group 2 are reversed, it is repeatedly painted for multiple times. After the paint film thickness requirement is reached, the painting process is completed. In order to ensure the curing and cooling time of the paint film during the production process, the running length of the enameled flat wire is relatively long, and there is a natural drooping phenomenon between the traveling guide wheel groups at both ends. The drooping degree varies according to the wire diameter and tension, and it is particularly not suitable for the high-speed production of wide flat wires. Flat wire painting is basically spraying paint on the bottom of the flat wire, and the four sides of the flat wire are painted through the painting mold. In the actual application test process, it was found that because it is liquid paint, the flat wire will not solidify immediately after painting. Due to the effect of gravity, the paint film on the lower surface is always thicker than the upper surface, resulting in a difference in the thickness of the paint film on the upper and lower wide surfaces of the flat wire. In order to meet the electrical performance requirements of the enameled wire, it is necessary to increase the overall paint film thickness, which increases the production cost. Therefore, the uniformity of the paint film thickness of the enameled wire needs to be further improved. Moreover, during the entire production process, the wiring section after the paint is cured and cooled is cooled by open natural wind. It is very easy to generate unorganized waste gas emissions during the production process, which cannot meet environmental protection requirements. In order to meet the market demand for enameled flat wires, improve the uniformity of the paint film thickness of enameled flat wires, and solve the industry problem of unorganized emissions of traditional enameling machines, it is urgent to develop a more energy-saving, environmentally friendly and efficient enameling machine production equipment for actual production. In addition, the waste gas heat in the oven body cannot be effectively utilized, wasting energy. Utility Model Content

[0028] The flat wire 12 enters the painting mechanism 15 from the lower channel 4 of the cooling section, and the painting mechanism 15 paints the flat wire lower side 12D of the flat wire 12, and then enters the interior of the baking furnace system 1, and then passes through the upper channel 2 11 of the cooling section, and after passing through, it changes direction through the reversing guide wheel 10 and enters the lower channel 2 9 of the cooling section, and enters the painting mechanism 28 from the lower channel 29 of the cooling section to paint the flat wire upper side 12U of the flat wire 12, and then enters the interior of the baking furnace system 1, and then passes through the upper channel 2 of the cooling section, and after passing through, it changes direction through the reversing guide wheel 3 and enters the next lower channel 4 of the cooling section, and multiple painting cycles are performed in this way.

[0030] See attached Figure 2 and 3 The cooling section upper channel 1 2, the cooling section lower channel 1 4, the cooling section upper channel 2 11 and the cooling section lower channel 2 9 have the same structure, and all include a circulating fan 201, a forced cooling device 1 202, a line box channel 203, a forced cooling device 2 204 and a bent pipe 205. The two ends of the forced cooling device 1 202 are respectively connected to the two ends of one side of the line box channel 203 through the corresponding bent pipes 205. The connecting end of the forced cooling device 1 202 and the line box channel 203 is provided with a circulating fan 201, and the other side of the line box channel 203 is provided with a forced cooling device 2 204. The cold source of the forced cooling device 1 202 and the forced cooling device 2 204 comes from an absorption refrigerator; when the flat wire 12 passes through the line box channel 203, the forced cooling device 1 202 and the forced cooling device 2 204 are used to force the flat wire 12 to cool, and at the same time, the exhaust gas released by the flat wire after painting is cooled in the line box channel and collected and then processed uniformly. Due to the effects of the circulating fan 201 and the arrangement of the pipeline, the line box channel 203 is always in a negative pressure state, and the waste gas released by the flat wire will not overflow, thus meeting the environmental protection requirements.

[0031] See attached Figure 5The bottom of the baking furnace system 1 is connected to the annealing device 7 through the exhaust gas pipeline 6; the annealing device 7 comprises an annealing heating tube 701 and a gas protection tube 703, and the annealing heating tube 701 and the gas protection tube 703 are arranged inside and outside to form a double-layer sleeve structure, and the exhaust gas pipeline 6 is connected to the annular channel between the annealing heating tube 701 and the gas protection tube 703, and the exhaust gas 702 in the baking furnace system 1 enters the annular channel from the exhaust gas pipeline 6, and the flat wire 12 passes through the annealing heating tube 701 and enters the lower channel 4 of the cooling section.

[0032] See attached Figure 2 The interior of the drying oven system 1 is provided with a hot air circulation fan system 101 and a hot air circulation fan system 2 102, and an air volume regulator is provided between the hot air circulation fan system 101 and the hot air circulation fan system 2 102. Through the pipeline arrangement and air volume regulation, the inlet and outlet of the drying oven body are always kept in a negative pressure state to prevent the volatile gas in the drying oven from overflowing.

[0033] See attached Figure 2 After passing through the annealing device 7, the flat wire 12 is turned by the guide wheel group and then enters the lower channel 4 of the cooling section.

[0034] See attached Figure 4 The paint mechanism 1 5 and the paint mechanism 2 8 have the same structure. The left wall, right wall and groove bottom of the paint channel of the paint mechanism 1 5 are provided with paint spraying ports to spray insulating paint on the flat wire. The paint spraying speed and flow rate of the paint spraying port can be adjusted, which is a well-known technology in the art.

[0035] The method of using the utility model includes the following steps:

[0036] ① The exhaust gas 702 inside the furnace system 1 enters the annular channel of the annealing device 7 from the exhaust gas pipe 6, pre-treats the flat wire 12 passing through the line box channel 203, and then the exhaust gas 702 in the annular channel is introduced into the absorption refrigerator, which provides a cold source for the strong cooling device 1 202 and the strong cooling device 2 204;

[0037] ② The pre-treated flat wire 12 enters the lower channel 4 of the cooling section for cooling, and then enters the painting mechanism 5, which sprays insulating paint on the flat wire bottom 12D of the flat wire 12, and then enters the baking furnace system 1 for baking;

[0038] ③ The flat wire 12 after baking enters the second channel 11 of the cooling section for cooling. After cooling, the flat wire 12 changes direction by the second reversing guide wheel 10 and enters the second channel 9 of the cooling section for cooling again. Then, the flat wire 12 enters the second painting mechanism 8. The second painting mechanism 8 sprays insulating paint on the flat wire upper surface 12U of the flat wire 12. The painted flat wire 12 enters the inside of the baking furnace system 1 for baking. The baked flat wire 12 enters the first channel 2 of the cooling section for cooling.

[0039] ④ After cooling, the flat wire 12 is reversed by the reversing guide wheel 3 and enters the next cooling section lower channel 4, and the painting is repeated for multiple times. After the painting is completed, the flat wire enters the next process.

[0040] In this embodiment, in order to achieve uniformity of the paint film on the upper and lower sides of the flat wire, a plurality of painting mechanisms 1 5 and painting mechanisms 2 8 are alternately arranged along the length direction on both sides of the baking furnace system 1, and a reversing guide wheel 1 3 is correspondingly arranged on the outer side of each painting mechanism 1 5, and a reversing guide wheel 2 10 is correspondingly arranged on the outer side of each painting mechanism 2 8. The flat wire is flipped up and down by the reversing guide wheel 1 3 and the reversing guide wheel 2 10.

[0041] The flat wire 12 enters the painting mechanism 1 5, which first paints the flat wire bottom 12D and both sides of the flat wire 12. After baking and cooling, the flat wire is flipped through the reversing guide wheel 2 10. At this time, the flat wire bottom 12D is located on the top, and the flat wire top 12U is located on the bottom. The painting mechanism 2 8 paints the flat wire top 12U and both sides, and then bakes and cools. In this reciprocating cycle, the flat wire bottom 12D and the flat wire top 12U are painted evenly for multiple times, thereby ensuring the uniformity of the paint film thickness on the upper and lower sides of the flat wire, saving materials and reducing costs.

[0042] The flat wire is moved in sequence along the cooling section lower channel 4, the painting mechanism 15, the inner cavity of the drying furnace system 1, the cooling section upper channel 2 11, the reversing guide wheel 10, the cooling section lower channel 2 9, the painting mechanism 2 8, the inner cavity of the drying furnace system 1, the cooling section upper channel 2, and the reversing guide wheel 3, i.e., it moves from bottom to top, then turns, and then moves from bottom to top, forming an X-shaped moving line mode, which can increase the tension of the flat wire and reduce the sagging degree of the flat wire, thus solving the technical problem that the horizontal machine cannot be used for the production of wide flat wires due to severe natural sagging during the moving line process.

[0043] The baking oven system 1 is used to bake the painted flat wire to complete the evaporation and solidification of the insulating paint; the cooling system is used to cool the baked flat wire. By using a strong cooling method, the cooling speed of the baked enameled wire is accelerated, which can significantly improve the overall production speed of the production line and improve production efficiency; the annealing device 7 is used for annealing pretreatment of the flat wire 12 to meet the use requirements of subsequent processes.

[0044] The cooling system 1 and the cooling system 2 are symmetrically arranged on both sides of the oven system 1. The cooling section upper channel 1 2, the cooling section lower channel 1 4, the cooling section upper channel 2 11 and the cooling section lower channel 2 9 are fully enclosed, and a special strong cooling device is installed to ensure the closed management of the unorganized residual waste gas of the enameling machine. The residual waste gas and smoke are collected and processed by strong cooling, which effectively solves the industry problem of unorganized emissions of traditional enameling machines, and has a significant environmental protection effect.

[0045] The annealing device 7 is arranged as a whole below the baking furnace system 1, cooling system 1 and cooling system 2, and is used for annealing the flat wire 12 to meet the use of subsequent processes. In view of the functional requirements of the annealing device, an electrically heated annealing heating tube 701 is used when starting the machine. After normal production, the exhaust gas 702 with a high temperature of about 550°C is directly introduced into the annealing device 7 through the exhaust gas pipeline 6 at the bottom of the baking furnace system 1, and the residual heat of the exhaust gas 702 is used to assist the annealing heating tube 701. At the same time, the exhaust gas 702 with a temperature of about 470°C after the annealing heating tube 701 is introduced into the absorption refrigerator to provide a cold source for the strong cooling device. The whole machine is energy-saving and environmentally friendly, and can realize the production of high-speed flat enameled wires. The heat of about 550°C is used to heat the annealing tube, and electric heating is used as a supplement, which has a significant energy-saving effect.
