DETAILED DESCRIPTION

[0024] The following is combined with Figure 1-3 This application is described in further detail.

[0025] The embodiment of the present application discloses an enameled wire paint supply system.

[0026] like Figure 1 and Figure 2 As shown, the enameled wire paint supply system includes a paint storage bucket 1, a paint supply bucket 2, an enameling furnace 3 and a paint supply pipeline.

[0027] like Figure 3 As shown, the paint storage bucket 1 is used to store paint. A new paint outlet is provided near the bottom of the outer wall of the paint storage bucket 1. In order to detect the amount of paint in the paint storage bucket 1, a pressure sensor 10 is also provided in the paint storage bucket 1. The paint in the paint storage bucket 1 directly acts on the diaphragm of the pressure sensor 10, causing the diaphragm to produce a micro-displacement proportional to the medium pressure, causing the resistance of the pressure sensor 10 to change. This change is detected by an electronic circuit, and a standard signal corresponding to this pressure is converted and output to obtain the pressure at the position of the pressure sensor 10 at this time. The built-in chip of the pressure sensor 10 can obtain the depth of the position of the pressure sensor 10 at this time through the conversion formula of pressure and depth, and then obtain the real-time paint stock in the paint storage bucket 1. Since the paint has a certain viscosity, in order to improve the measurement accuracy of the pressure sensor 10, the pressure sensor 10 is set at a position of one-quarter to one-third of the total height of the paint storage bucket 1.

[0028] like Figure 1 and Figure 2 As shown, the paint supply pipeline includes a paint inlet pipeline 4, a paint return pipeline 6 and a paint supply pipeline 5, and the paint inlet pipeline 4, the paint return pipeline 6 and the paint supply pipeline 5 are all provided with a power pump 7 and a paint supply flow sensor 8.

[0029] like Figure 1-Figure 3 As shown, a heating component for heating the paint and a stirring component for stirring the paint are provided in the paint supply bucket 2, a paint receiving port and a paint return port are provided near the top of the outer wall of the paint supply bucket 2, and a paint supply port is provided near the bottom of the outer wall of the paint supply bucket 2. The new paint outlet of the paint storage bucket 1 is connected to the paint receiving port of the paint supply bucket 2 through a paint inlet pipe 4 to provide paint to the paint supply bucket 2.

[0030] like Figure 3 As shown, the stirring assembly includes a stirring motor 11 installed on the top of the paint supply bucket 2, and a stirring shaft 12 is provided at the output end of the stirring motor 11. The stirring shaft 12 passes through the top of the paint supply bucket 2 and extends into the paint supply bucket 2. A plurality of sleeves 13 are fixedly connected to the stirring shaft 12, and stirring blades 14 are provided on both sides of the sleeves 13.

[0031] Start the stirring motor 11, which can drive the stirring shaft 12 to rotate around its own axis, thereby driving the sleeve 13 and the paddles to rotate around the axis of the stirring shaft 12, thereby stirring the paint in the paint bucket 2 to ensure uniform mixing of the paint and improve the quality of the enameled wire.

[0032] like Figure 3 As shown, the heating component includes an electric heating wire installed at the bottom of the paint supply bucket 2, and the paint in the paint supply bucket 2 can be heated by the electric heating wire to reach the temperature required by the enameling furnace 3.

[0033] like Figure 3 As shown, in order to grasp the amount of paint in the paint supply bucket 2, a height ruler 17 is also provided in the paint supply bucket 2. The height ruler 17 is arranged in the vertical direction. The distance between the height ruler 17 and the stirring shaft 12 is greater than the length of the stirring blade 14, and the distance between the height ruler 17 and the stirring shaft 12 is smaller than the distance between the stirring shaft 12 and the inner wall of the paint supply bucket 2. The height ruler 17 is provided with a plurality of paint passing holes which are evenly spaced along the vertical direction, and the paint passing holes are perpendicular to the radial direction of the stirring shaft 12. A stock flow sensor 18 is provided at the paint passing hole, and the stock flow sensor 18 is connected to the signal of the power pump 7 located at the paint inlet pipe 4.

[0034] In the actual production process, since the paint is viscous, it is difficult for the traditional liquid level sensor to accurately detect the amount of paint in the paint supply bucket 2. Since the stirring component is stirring the paint, it is difficult for the pressure sensor 10 to calculate the current amount of paint in the paint supply bucket 2 by detecting the pressure. Since the stirring component will make the paint fluid in the process of stirring the paint, the present application sets a height ruler 17 in the paint supply bucket 2. The height ruler 17 is provided with a plurality of paint holes at equal intervals in the vertical direction, and the paint holes are perpendicular to the radial direction of the stirring shaft 12. The paint holes perpendicular to the radial direction of the stirring shaft 12 can enable the stirring component to drive the paint to pass through the paint holes in the process of stirring the paint. By setting the amount flow sensor 18 at the paint hole, it can detect whether there is paint passing through the paint hole at the current height position, thereby judging the amount of paint in the paint supply bucket 2. After multiple stock flow sensors 18 work together to determine the stock of paint in the paint supply bucket 2, based on the specific stock, the stock flow sensor 18 can send a signal to the power pump 7 located at the paint supply pipe 4, thereby controlling the working state of the power pump 7 located at the paint supply pipe 4 to replenish paint into the paint supply bucket 2 through the paint supply pipe 4.

[0035] In this embodiment, the stock flow sensors 18 are all traditional baffle flow sensors. Since the baffle flow sensors in this application are only used to measure whether there is paint circulation, even if the baffle flow sensors are impacted by paint for a long time and the set point drifts, it will not affect the normal operation. The paint supply flow sensors 8 are all clamp-type sensors. The paint supply pipeline is used to transfer paint. Too many pipeline interfaces are prone to paint leakage. In order to reduce the leakage risks caused by more pipeline interfaces, a clamp-type sensor is installed on the outside of the pipeline. The two ultrasonic transmitters and receivers of the clamp-type sensor are used to measure the paint flow rate by the change of the propagation time of the ultrasonic beam in the pipeline. Specifically, when the ultrasonic signal propagates in the pipeline, due to the flow of paint in the pipeline, the propagation time of the ultrasonic signal will change with the change of the paint flow rate. The clamp-type sensor can calculate the flow rate and flow of the paint by measuring the time difference between the propagation of the ultrasonic beam in the pipeline and the upstream propagation.

[0036] like Figure 1-Figure 3 As shown, a nozzle for painting copper wire is provided in the enameling furnace 3, a nozzle interface connected to the nozzle is provided at the top of the enameling furnace 3, and a secondary paint outlet is provided near the bottom of the outer wall of the enameling furnace 3. The paint supply port of the paint supply bucket 2 is connected to the nozzle interface of the enameling furnace 3 through the paint supply pipe 5 to provide paint to the enameling furnace 3. The secondary paint outlet of the enameling furnace 3 is connected to the paint return port of the paint supply bucket 2 through the paint return pipe 6 to recycle the paint not attached to the wire to the paint supply bucket 2. In order to detect the pressure in the paint supply pipe 5, a pressure gauge 9 is also provided at one end of the paint supply pipe 5 near the nozzle interface. The pressure gauge 9 can monitor the pressure change in the paint supply process in real time to ensure the stability of the nozzle operation. It can be understood that the enameling furnace 3 is also provided with a wire inlet and a wire outlet for the wire to pass through, and the enameling furnace 3 is also provided with a wheel group for winding and guiding the wire, but the wire inlet and wire outlet and the wheel group are not the focus of protection of this application, so they are not shown in the figure.

[0037] like Figure 3As shown, in order to reduce the influence of impurities on the enameled wire, a first filter 15 for filtering the paint provided by the paint storage bucket 1 and the paint discharged from the enameling furnace 3 and a second filter 16 for filtering the paint stirred in the paint supply bucket 2 are provided in the paint supply bucket 2. The first filter 15 is located lower than the paint receiving port and the paint return port in the vertical direction, and the second filter 16 is located lower than the first filter 15 in the vertical direction and higher than the paint supply port. The elevation scale 17 is located between the first filter 15 and the second filter 16. Both the first filter 15 and the second filter 16 are provided with through holes for the stirring shaft 12 to pass through. After the paint is filtered by the first filter 15, the influence of impurities on the stock flow sensor 18 can be reduced. After the paint is double filtered by the first filter 15 and the second filter 16, the purity of the paint entering the enameling furnace 3 through the supply pipe can be guaranteed, thereby ensuring the quality of the enameled wire.

[0038] In order to be able to respond to abnormal situations in time, the paint supply system also includes an alarm, which is simultaneously connected to the pressure gauge 9, the pressure sensor 10 and the paint supply flow sensor 8. The alarm may include a warning light or a buzzer. When the pressure gauge 9, the pressure sensor 10 or the paint supply flow sensor 8 detects an abnormal situation, the alarm can be issued in time through the alarm to remind the production personnel to take measures.

[0039] The implementation principle of the paint supply system for enameled wire in the embodiment of the present application is as follows: the paint supply system is started, and the heating component and the stirring component start working. After multiple stock flow sensors 18 work together to determine the stock of paint in the paint supply bucket 2, according to the specific stock, the stock flow sensor 18 sends a signal to the power pump 7 located at the paint supply pipeline 4, thereby controlling the working state of the power pump 7 located at the paint supply pipeline 4, so as to replenish the paint into the paint supply bucket 2 through the paint supply pipeline 4 until the paint stock in the paint supply bucket 2 can meet the working needs of the enameling furnace 3. At the same time as the heating component and the stirring component start working, the power pump 7 located on the paint supply pipeline 5 and the power pump 7 located on the paint return pipeline 6 start working, and the paint starts to circulate in the system until the readings of the pressure gauge 9, the pressure sensor 10 and the paint supply flow sensor 8 are all within the required working range, and then the wire starts to be supplied to the enameling furnace 3.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
