The nozzle has a groove for fixing felt, and the groove cavity is located on the travel path of the enameled wire. The reservoir has a receiving cavity for holding lubricating fluid. The bottom of the receiving cavity is connected to the inlet of the micro-pump via a first flow channel, and the outlet of the micro-pump is connected to the felt at the nozzle via a second flow channel. Both the first and second flow channels are L-shaped pipes passing through the reservoir body, and a heating element for heating the lubricating fluid is embedded inside the L-shaped bends of each flow channel. This device is easy to install and flexible to control. It can ensure the coating quality of the product surface while saving production costs, and simultaneously eliminates harm to the human body and pollution to the environment. The operational safety of the entire coating process is significantly improved.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Existing hot wax uniform coating devices heat the lubricating oil in the delivery pipe 8 at the same temperature, resulting in heat loss and making it inconvenient to apply the lubricating oil evenly and comprehensively. In order to solve this technical problem, this embodiment discloses the following technical content.

[0029] Please see Figures 1-5 A uniform coating device for hot wax with temperature gradient control includes a protective box 1, an observation window 2, a controller 3, a material pump 4, a storage box 5, a box cover 6, a first heating plate 7, a conveying pipe 8, a control box 9, a partition 10, a second heating plate 11, a temperature sensor 12, a mounting ring 13, a screw 14, an arc-shaped shell 15, a felt 16, and a hollow ring 17.

[0030] The protective box 1 is equipped with an observation window 2 at the front end, and a storage box 5 is installed inside the protective box 1. The storage box 5 is a transparent structure, and the content of lubricating fluid inside the storage box 5 can be observed through the observation window 2.

[0031] A controller 3 is installed on the front side of the protective box 1, which controls the material pump 4, the first heating plate 7, the second heating plate 11 and the temperature sensor 12.

[0032] The top of the storage box 5 is equipped with a box cover 6, and the outer side of the storage box 5 is equipped with a first heating plate 7. The first heating plate 7 is installed at equal angles on the outside of the storage box 5. The first heating plate 7, which is set at equal angles, can fully heat the lubricating oil inside the storage box 5.

[0033] A material pump 4 is installed on the right side of the protective box 1. The output end of the material pump 4 is connected to a conveying pipe 8, and the input end of the material pump 4 is connected to a storage tank 5 through a pipe. The material pump 4 is started by the controller 3, and the lubricating oil inside the storage tank 5 is conveyed to the coating contact component through the conveying pipe 8 under the action of the material pump 4.

[0034] A temperature gradient control component is provided on the left side of the protective box 1. The temperature gradient control component can ensure the temperature of the lubricating oil in the delivery pipe 8. The temperature gradient control component includes a control box 9, a partition 10, a second heating plate 11, and a temperature sensor 12. The control box 9 is equipped with a partition 10, which divides the control box 9 into multiple heating chambers. The temperature sensor 12 is provided in each heating chamber. The delivery pipe 8 is fixed inside the partition 10. The second heating plate 11 is installed at the bottom and on the left inner wall of the control box 9.

[0035] like Figure 1 and Figure 4As shown, water pipes are installed at both the front and rear ends of the control box 9. The water pipes are connected to the external water supply equipment and water is supplied to each heating chamber through the water pipes. The water in the heating chamber is heated by the second heating plate 11. The hot water is used to maintain the temperature of the lubricating oil inside the delivery pipe 8. The right end of the delivery pipe 8 is located in the vacuum chamber formed between the protective box 1 and the storage box 5. Therefore, the part of the delivery pipe 8 located in the vacuum chamber has the lowest cooling rate. As the delivery pipe 8 gradually moves away from the storage box 5, the temperature inside the delivery pipe 8 gradually decreases. The temperature of the heating chamber in the control box 9 gradually increases from the lower right to the upper right. This ensures that the lubricating oil in the delivery pipe 8 is within the required temperature range and reduces energy consumption.

[0036] Temperature sensor 12 detects the temperature in each heating chamber and transmits the temperature information to controller 3. Controller 3 controls the heating intensity of the second heating plate 11.

[0037] The left side of the temperature gradient control component is provided with a coating contact component that can apply the coating evenly. The coating contact component includes a mounting ring 13, a screw 14, an arc-shaped shell 15, a felt 16, and a hollow ring 17. The screw 14 is internally threaded to the mounting ring 13. The arc-shaped shell 15 is rotatably connected to the inner end of the screw 14. The felt 16 is pasted to the inner side of the arc-shaped shell 15. The hollow ring 17 is fixed to the inner wall of the mounting ring 13. The nozzles are installed at equal angles at the top and bottom of the hollow ring 17.

[0038] The enameled wire passes through the mounting ring 13. The distance between the arc-shaped shell 15 and the felt 16 is adjusted according to the diameter of the enameled wire. The screw 14 is manually rotated to move the arc-shaped shell 15 and adjust the distance between the two sets of arc-shaped shells 15 to accommodate enameled wires of different diameters. Since the arc-shaped shell 15 is symmetrically arranged about the center line of the hollow ring 17 and the upper and lower sets of felt 16 of the hollow ring 17 are staggered, the upper and lower sets of felt 16 can fully wrap the enameled wire. The delivery pipe 8 delivers lubricating oil to the inside of the hollow ring 17. The lubricating oil is sprayed from the nozzle on the hollow ring 17 onto the felt 16, and the lubricating oil inside the felt 16 is evenly coated on the outer surface of the enameled wire.

[0039] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
