Abstract
Description
Technical Field
[0001] This utility model relates to the field of enameled wire processing technology, and in particular to an enameled wire production enameled wire supply device. Background Technology
[0002] In existing enameled wire enamel supply devices, the temperature of the enamel liquid flowing to the felt in the coating device is significantly lower than the temperature set in the enamel box. This large temperature difference affects the permeability of the felt, preventing the enamel liquid from being evenly coated on the conductor surface, resulting in uneven enamel film coating. Furthermore, relying on a enamel pump for enamel supply often leads to pump jamming or intermittent enamel supply, resulting in unstable enamel supply, which also causes uneven enamel film coating and affects the quality of the enameled wire. Utility Model Content

[0016] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0018] like Figure 1As shown, a preferred embodiment of the present invention provides a paint supply device for enameled wire production, comprising a frame (not shown) and a heating paint tank 1 and a paint supply tank 2 mounted on the frame. Both the walls of the heating paint tank 1 and the paint supply tank 2 are equipped with built-in constant-temperature heaters. A conveying pipe 3 connects the heating paint tank 1 and the paint supply tank 2. The first end of the conveying pipe 3 is connected to the bottom of the heating paint tank 1, and a regulating valve 4 is provided at the first end of the conveying pipe 3. The second end of the conveying pipe 3 is connected to the top of the paint supply tank 2. The bottom surface of the heating paint tank 1 is higher than the top surface of the paint supply tank 2. The heating paint tank 1 and the paint supply tank 2 are arranged side-by-side or front-to-back to facilitate maintenance of the paint supply tank 2 and to prevent the heating paint tank 1 from being directly above the paint supply tank 2 and affecting its maintenance. Multiple paint drip nozzles 5 are provided at the bottom of the paint supply tank 2.
[0019] The constant temperature heaters on the heating paint tank 1 and the paint supply tank 2 of this utility model can ensure that the temperature of the paint liquid delivered from the paint supply nozzle 5 is constant. The height difference between the heating paint tank 1 and the paint supply tank 2 allows the paint liquid in the heating paint tank 1 to flow into the paint supply tank 2 under the action of gravity. The opening of the regulating valve 4 on the delivery pipe 3 can control the amount of paint liquid supplied and reduce the pressure fluctuation of the paint liquid, ensuring good coating uniformity in the next process. There is no need for a paint pump to transport the paint, thus reducing equipment and operating costs.
[0020] For example, the heating paint tank 1 is equipped with a stirring motor 6, and the heating paint tank 1 is equipped with a stirring shaft 7 connected to the output end of the stirring motor 6, which effectively prevents the paint liquid in the heating paint tank 1 from settling and ensures that the paint liquid is uniform.
[0021] For example, the heating paint box 1, the conveying pipe 3 and the paint supply box 2 are all covered with a layer of heat-insulating material to prevent heat loss and increase energy consumption.
[0022] For example, the heating paint tank 1 is equipped with a liquid level sensor, which can know the liquid level in the heating paint tank 1 in real time. The amount of paint supplied to the paint supply tank 2 can be controlled by the liquid level in the heating paint tank 1. In conjunction with the opening of the regulating valve 4 on the delivery pipe 3, the amount of paint supplied can be precisely controlled.
[0023] In this embodiment, the paint inlet of the paint supply box 2 is located on the top surface of the paint supply box 2, and two conveying pipes 3 are arranged side by side on the left and right sides to enhance the conveying flexibility. The conveying pipes 3 can be inclined downwards.
[0024] For example, the paint inlet is equipped with a regulating valve 4 to further improve the accuracy of regulating the flow rate of paint entering the paint supply tank 2.
[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
