[0002] In the field of new energy vehicles, customers have relatively strict requirements for the paint coating effect. As one of the important indicators for evaluating the quality of enamelled wire products, the paint supply stability can directly reflect the coating effect of the enamelled wire.

[0003] The enamelled wire is coated in the paint tank inside the enamelling equipment. The internal insulating paint will be consumed during the coating process, and it is necessary to manually add insulating paint to the paint tank regularly to ensure that the enamelled wire is evenly coated with insulating paint. Manual addition is labor-intensive and very cumbersome, and the paint is easy to splash during pouring, resulting in quality problems of the enamelled wire. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an automatic paint supply device for enamelled wires to solve at least one of the problems and defects mentioned in the above background art.

[0005] An automatic paint supply device for enamelled wires includes a paint storage bucket. A first float switch, a second float switch, and a third float switch are successively arranged on the barrel wall of the paint storage bucket from low to high. The floats associated with the three float switches are all arranged inside the paint storage bucket. An electric valve communicating the inside and outside of the paint storage bucket is also arranged on the barrel wall of the paint storage bucket, and the electric valve is communicatively connected with the three float switches;

[0006] The paint storage bucket is connected to the inside of the enamelling equipment through a pipeline, and a drainage motor is arranged on the pipeline.

[0007] Further, a paint supply valve is arranged at the end of the pipeline connecting the paint storage bucket and the enamelling equipment. By adjusting the opening degree of the paint supply valve, the amount of paint output to the paint tank inside the enamelling equipment can be adjusted.

[0008] Further, a return port is opened on the paint storage bucket, and the return port is connected to the overflow port of the enamelling equipment through a pipeline. When the paint liquid in the paint tank inside the enamelling equipment is excessive, it will flow into the overflow port and flow back to the paint storage bucket through the return port to realize the circulation of the paint liquid.

[0009] Further, a bucket cover is arranged on the top of the paint storage bucket. The bucket cover is locked on the top of the paint storage bucket through a buckle, and the bucket cover can be removed by unlocking the buckle.

[0010] Further, a cleaning valve communicating the inside and outside of the paint storage bucket is arranged at the bottom of the paint storage bucket. After cleaning the paint storage bucket, the cleaning valve can be opened to drain the sewage.

[0011] Further, the paint storage bucket is installed on a mobile base, and universal wheels are arranged at the bottom of the mobile base.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In this solution, a paint storage bucket is designed to supply paint to the enameling equipment. Three float switches are designed in the paint storage bucket from low to high. An electric valve is arranged at the inlet of the paint storage bucket and is communicatively connected to the three float switches. The electric valve is connected to the paint replenishing equipment. When the paint liquid in the paint storage bucket is lower than the lowest float switch, the electric valve is activated to introduce the paint liquid into the paint storage bucket. When the paint liquid in the paint storage bucket reaches the middle float switch, the electric valve receives a signal and closes to stop the paint supply. The highest float switch is for warning design. When the middle float switch is damaged, the paint liquid will continuously rise in the paint storage bucket. When it reaches the position of the highest float switch, the highest float switch receives a signal and closes to stop the paint supply. The outlet of the paint storage bucket is connected to the internal paint tank of the enameling equipment through a pipeline. A drainage motor is arranged on the pipeline to introduce the paint liquid in the paint storage bucket into the internal paint tank of the enameling equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model, and are not used to limit the present utility model, that is, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Generally, the components of the embodiments of the present utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0018] Therefore, the detailed description of the embodiments of the present utility model provided in the drawings below is not intended to limit the scope of the present utility model to be protected, but only represents the selected embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0019] Please refer to Figure 1As shown in the figure, in the embodiment of the present utility model, an automatic paint supply device for enamelled wires includes a paint storage barrel 1. On the barrel wall of the paint storage barrel 1, a first float switch 301, a second float switch 302, and a third float switch 303 are successively arranged from low to high. The floats associated with the three float switches are all arranged inside the paint storage barrel 1. An electric valve 2 communicating the inside and outside of the paint storage barrel 1 is also provided on the barrel wall of the paint storage barrel 1. The electric valve 2 is connected to a paint replenishment device, and the electric valve 2 is communicatively connected to the three float switches. When the paint liquid in the paint storage barrel 1 is insufficient and the liquid level drops below the first float switch 301, the float associated with the first float switch 301 will sag due to the loss of buoyancy and follow gravity. The built-in switch of the first float switch 301 is triggered by the sagging of the float, and a signal is output to start the electric valve 2 to introduce the paint liquid into the paint storage barrel 1. When the paint liquid level in the paint storage barrel 1 rises to the position of the second float switch 302, the float associated with the second float switch 302 floats up to trigger the built-in switch, and a signal is output to close the electric valve 2 to stop the paint supply. The third float switch 303 serves as a warning switch. When the second float switch 302 is damaged, the paint liquid level rises to the third float switch 303 to trigger the switch, and a signal is output to close the electric valve 2 to stop the paint supply. An alarm device can be added to be linked with the third float switch 303. When the third float switch 303 is activated, a warning will be given to check for faults.

[0020] Among them, the paint storage barrel 1 is connected to the internal paint tank of the enamelling device through a pipeline. A drainage motor 6 is provided on the pipeline, and the paint liquid in the paint storage barrel 1 is introduced into the paint tank through the drainage motor 6. Through the above design, automatic paint supply to the internal paint tank of the enamelling device can be realized, so as to save energy resources, ensure the stability of paint supply, and avoid affecting the quality of enamelled wires due to paint supply.

[0021] In one embodiment, a paint supply valve 5 is provided at the end of the pipeline connecting the paint storage barrel 1 and the enamelling device. The paint supply valve 5 can be adjusted according to requirements, so as to flexibly adjust the amount of paint liquid output into the paint tank.

[0022] In one embodiment, a reflux port 7 is opened on the paint storage barrel 1. The reflux port 7 is connected to the overflow port of the enamelling device through a pipeline. The overflow port is arranged at the position of the paint tank. When the paint liquid in the paint tank is too much and exceeds the overflow port, the paint liquid will flow into the paint storage barrel 1 through the connected reflux port 7 along the pipeline to achieve automatic circulation. This design can prevent the paint liquid in the paint supply device from overflowing.

[0023] In one embodiment, a barrel cover 101 is provided on the top of the paint storage barrel 1. The barrel cover 101 is fastened to the top of the paint storage barrel 1 by a buckle. When it is necessary to clean or repair the inside of the paint storage barrel 1, only the buckle needs to be untied, and the barrel cover 101 can be removed, which is convenient for maintenance and cleaning.

[0024] In one embodiment, a cleaning valve 8 communicating the inside and outside of the paint storage bucket 1 is provided at the bottom of the paint storage bucket 1. After cleaning the inside of the paint storage bucket 1, there is no need to pour it with effort. Just open the cleaning valve 8, and the sewage can be discharged from the paint storage bucket 1.

[0025] In one embodiment, the paint storage bucket 1 is mounted on a moving base 4 through a bracket. Universal wheels are provided at the bottom of the moving base 4. The paint supply device can be moved arbitrarily according to needs through the moving base 4, which is simple and convenient.
