AI Technical Summary
During the production of enameled flat wire, the different shapes of the conductive cores require frequent adjustments to the spray angle of the nozzle when applying insulating varnish, which makes production quite difficult.
The system employs a vertical tube structure, with the conductive wire core passing through the gap between the vertical tube and its inner wall, which is filled with insulating varnish. The adhesion of the varnish is controlled by the gap between the inner wall of the vertical tube and the wire core, eliminating the need for nozzle angle adjustment and simplifying the production process.
This reduces the need for nozzle angle adjustment, lowers production difficulty, and improves the adhesion and drying efficiency of the insulating varnish.

[0002] Enamelled flat wire is a type of enamelled wire with a larger width on the front and a smaller width on the side. During its production, the conductive core needs to be sprayed with insulating varnish and then dried. Because the shape of the front side of the enamelled flat wire is different from that of the side side, the spraying angle of the nozzle needs to be adjusted frequently during the spraying process, making the production relatively difficult.

A first partition is installed inside the housing, dividing it into an upper chamber and a lower chamber. A vertical tube for a conductive wire core to pass through is fixed to the first partition, penetrating the first partition. A varnish supply pipe is connected to the side of the vertical tube, extending beyond the housing. When the conductive wire core passes through the vertical tube, a gap exists between the conductive wire core and the inner wall of the vertical tube. A first rubber stopper is disposed on the bottom surface of the housing corresponding to the vertical tube, penetrating the bottom surface of the housing. The first rubber stopper has a first through hole for the conductive wire core to pass through, and when the conductive wire core passes through the first rubber stopper, it is in contact with the inner wall of the first rubber stopper. A second rubber stopper is disposed on the top surface of the housing corresponding to the vertical tube, penetrating the top surface of the housing. The second rubber stopper has a second through hole for the conductive wire core to pass through, and when the conductive wire core passes through the second rubber stopper, it is in contact with the inner wall of the second rubber stopper.

[0007] Preferably, a second partition is installed between the top surface of the outer shell and the first partition, the second partition dividing the upper chamber into a first upper chamber and a second upper chamber, the first upper chamber being located above the second upper chamber, and the top end of the vertical tube being located below the second partition; a third through hole for the conductive wire core to pass through is provided on the second partition corresponding to the position of the vertical tube; the electric heating device and the permeable brick are located above the second partition.

A first support rod is fixed on the first bracket, and a first rotating wheel is rotatably connected to the first support rod corresponding to the position of the paint supply pipe. A second support rod is fixed on the second bracket, and a second rotating wheel is rotatably connected to the second support rod corresponding to the position of the paint supply pipe.
[0009] Preferably, a ventilation chamber is provided between the first bracket and the outer shell, and the top surface of the outer shell and the bottom surface of the ventilation chamber share the same surface; the top surface of the ventilation chamber is provided with a fourth through hole for the conductive wire core to pass through; a second vent pipe and a third vent pipe are provided on the outer wall of the ventilation chamber, both of which are located outside the ventilation chamber; a second valve is installed on the second vent pipe, and a third valve is installed on the third vent pipe; the second vent pipe and the third vent pipe are respectively connected to the ventilation chamber.

[0012] The enameled flat wire production apparatus provided by this invention provides an insulating varnish supply to a pre-connected varnish supply device in the varnish supply pipe. The conductive wire core moves upward sequentially through the first through hole of the first rubber plug and the second through hole of the second rubber plug in the vertical tube. During the upward movement, the insulating varnish continuously flows into the vertical tube, filling the gap between the conductive wire core and the inner wall of the vertical tube. In this way, the insulating varnish adheres to the conductive wire core as it moves upward. This structure controls the contact between the insulating varnish and the conductive wire core through the gap between the inner wall of the vertical tube and the conductive wire core. When producing enameled flat wire, compared with the spraying method, it is not necessary to adjust the spraying angle of the nozzle, and the production difficulty is relatively small.

Detailed Implementation
[0014] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.
[0015] Example: This invention provides an apparatus for producing enameled flat wire, see [link to example]. Figure 1 The device includes an outer casing 10, within which a first partition 11 is installed, dividing the casing into an upper chamber 10-1 and a lower chamber 10-2. A vertical tube 12 for a conductive wire core to pass through is fixed on the first partition. The vertical tube penetrates the first partition, with its top end located in the upper chamber and its bottom end located in the lower chamber. A paint supply tube 13 is connected to the side of the vertical tube, extending beyond the outer casing. When the conductive wire core passes through the vertical tube, there is a gap between the conductive wire core and the inner wall of the vertical tube. (See manufacturing instructions for reference.) Figure 2 The cross-sectional shape of the vertical tube hole 12-1 is the same as that of the conductive wire core, and is larger than the cross-sectional area of the conductive wire core. A first rubber plug 14 is provided on the bottom surface of the outer shell corresponding to the vertical tube. The first rubber plug penetrates the bottom surface of the outer shell and has a first through hole for the conductive wire core to pass through. When the conductive wire core passes through the first rubber plug, the conductive wire core is in contact with the inner wall of the first rubber plug. A second rubber plug 15 is provided on the top surface of the outer shell corresponding to the vertical tube. The second rubber plug penetrates the top surface of the outer shell and has a second through hole for the conductive wire core to pass through. When the conductive wire core passes through the second rubber plug, the conductive wire core is in contact with the inner wall of the second rubber plug. A first vent pipe 16 is installed on the outer shell corresponding to the lower chamber, and a first valve 17 is installed on the first vent pipe.
[0016] In the above-mentioned enameled flat wire production device, the varnish supply pipe is pre-connected to the varnish supply device to provide insulating varnish, and the first vent pipe is pre-connected to the induced draft device or vacuum device. First, the conductive wire core is passed sequentially through the first through hole of the first rubber plug, the second through hole of the second rubber plug of the vertical tube, and then pulled by the traction device. During traction, the conductive wire core is kept straight. Before the wire core is to be pulled, the first valve is opened, and the induced draft device or vacuum device is started to create a negative pressure in the lower chamber. At this time, the traction device can be controlled to pull the conductive wire core upward. During the upward movement, the insulating varnish flows continuously into the vertical tube, filling the gap between the conductive wire core and the inner wall of the vertical tube. In this way, the insulating varnish adheres to the conductive wire core during the upward movement. This structure uses the shape of the tube hole of the vertical tube to control the contact between the insulating varnish and the conductive wire core. When producing enameled flat wire, compared with the spraying method, it is not necessary to adjust the spray angle of the nozzle, and the production difficulty is relatively small. After the conductive core coated with insulating varnish moves upward and protrudes from the vertical tube, it evaporates and dries in the upper chamber to form an enameled flat wire. Then, after passing through the second rubber stopper, it protrudes from the housing and is collected. During use, because the upper and lower chambers are pre-generated with negative pressure, the gas in the upper chamber is not easily sucked into the lower part of the varnish supply position of the vertical tube when the insulating varnish enters, thus avoiding mixing with the subsequently entering insulation and generating bubbles. In addition, during the evaporation and drying process, the upper chamber has a certain negative pressure, resulting in a relatively good evaporation and drying effect.
[0017] As a preferred embodiment, an electric heating device 18 is installed in the upper chamber above the vertical pipe, and a permeable brick 19 is fixed on the outer shell at a position corresponding to the upper chamber. The permeable brick penetrates the outer shell. During this drying process, the upper chamber can be heated by the electric heating device to improve the evaporation efficiency. After being heated, the permeable brick is more conducive to introducing water vapor into the outer shell.
[0018] As a preferred implementation method, see [link to relevant documentation]. Figure 7 A second partition 20 is installed between the top surface of the outer shell and the first partition, dividing the upper chamber into a first upper chamber 10-11 and a second upper chamber 10-12. The first upper chamber is located above the second upper chamber, and the top end of the vertical tube is located below the second partition. A third through hole for the conductive wire core to pass through is provided on the second partition corresponding to the position of the vertical tube. The electric heating device and the permeable brick are located above the second partition. By setting the second partition to isolate the temperature between the first and second upper chambers, it is beneficial to maintain the temperature inside the vertical tube.
[0019] In a preferred embodiment, a first bracket 21 is installed at the bottom of the housing, and a second bracket 22 is installed at the top of the housing. A first support rod 23 is fixed on the first bracket, and a first rotating wheel 24 is rotatably connected to the first support rod corresponding to the position of the paint supply pipe. A second support rod 25 is fixed on the second bracket, and a second rotating wheel 26 is rotatably connected to the second support rod corresponding to the position of the paint supply pipe. By setting the first and second rotating wheels, the insulated wire core can pass around the first rotating wheel and enter the housing during use, and then pass around the second rotating wheel after exiting the housing. This changes the direction of movement of the insulated wire. Furthermore, the positions of the first and second rotating wheels are pre-set to maintain the insulated wire core in the position of the vertical tube during use. In this embodiment, multiple devices such as the first rotating wheel, the second rotating wheel, and the vertical tube can be provided. In actual use, the suction force of the air-guiding device or the vacuum device can be adjusted according to the upward movement speed of the conductive wire core to adjust the flow rate of the insulating paint.
[0020] As a preferred implementation method, see [link to relevant documentation]. Figure 7 A ventilation chamber 10-3 is provided between the first bracket and the outer shell. The top surface of the outer shell and the bottom surface of the ventilation chamber share the same surface, meaning the top surface of the outer shell is also the bottom surface of the ventilation chamber. A fourth through hole for the conductive wire core to pass through is provided on the top surface of the ventilation chamber. A second vent pipe 27 and a third vent pipe 28 are provided on the outer wall of the ventilation chamber. Both the second and third vent pipes are located outside the ventilation chamber. A second valve 29 is installed on the second vent pipe, and a third valve 30 is installed on the third vent pipe. The second and third vent pipes are respectively connected to the ventilation chamber. By providing the ventilation chamber, the first vent pipe, and the second vent pipe, a fan can be connected to the second vent pipe during use. After the enameled flat wire enters the ventilation chamber, the second and third valves are opened, and the fan is started to generate airflow in the ventilation chamber, cooling the enameled flat wire and further drying it.
[0021] In one embodiment, the first bracket includes two first H-shaped brackets, one of which is fixed to one side of the outer casing, and the other is fixed to the other side of the outer casing; the second bracket includes two second H-shaped brackets, one of which is fixed to one side of the outer casing, and the other is fixed to the other side of the outer casing. The shapes of the first H-shaped brackets and the second H-shaped brackets are as follows: Figure 6 As shown.
[0022] As a preferred implementation method, see [link to relevant documentation]. Figures 3-5The first through hole includes a first frustum-shaped hole 14-1 and a first cylindrical hole 14-2. The diameter of one end of the first frustum-shaped hole connected to the first cylindrical hole is smaller than the diameter of the other end, and the first frustum-shaped hole is located below the first cylindrical hole. The shape of the second through hole is the same as that of the first through hole, and will not be described again here. This structure makes it easier for the conductive wire core to pass through the first through hole and the second through hole. In this embodiment, the first and second rubber plugs can be rubber plugs or silicone plugs.
