Description

Technical Field

[0001] The utility model relates to the technical field of enamelled wire painting, in particular to a painting device for a fine enamelled wire suspension die. Background Art

[0002] In the traditional enamelled wire production process, the method of removing the excess paint on the surface of the enamelled wire mainly relies on the mutually attached felts. However, this method has significant defects: due to the limited control accuracy of the felt attachment surface, it is difficult to ensure the uniformity of the paint thickness, resulting in uneven film thickness of the enamelled wire and seriously affecting the overall quality of the product.

[0003] In order to improve the uniformity of the paint film and the product quality, the industrial circle has gradually turned to using a suspension die for painting. The suspension die, with its precisely designed channel structure, realizes uniform painting on the surface of the enamelled wire. However, with the diversified development of the outer diameter of enamelled wire products, the fixed-specification suspension die cannot meet the painting requirements of enamelled wires with different outer diameters. Therefore, during the production process, whenever the outer diameter of the enamelled wire changes, it is necessary to frequently replace the suspension die and adjust the position of the spray head.

[0004] However, at present, the replacement operation of the suspension die mostly relies on manual labor, including steps such as disassembling the old die, installing the new die, and precisely adjusting the position of the spray head. The operation process is relatively cumbersome and inefficient, and it is difficult to meet the requirements of modern high-efficiency production. Content of the Utility Model

The examples of the embodiments are shown in the drawings, where the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model. On the contrary, the embodiments of the present utility model include all changes, modifications and equivalents falling within the spirit and connotation of the appended claims.

[0027] The following will describe a coating device for a micro enameled wire suspension mold according to an embodiment of the present utility model with reference to the drawings.

Among them, the secondary mounting frame 2 and the conical paint coating box 3 are respectively fixedly connected to the surface of the main mounting frame 1 and are arranged up and down along the Z-axis direction; the switching turntable seat 4 is rotatably connected to the surface of the secondary mounting frame 2, and a plurality of groups of suspension molds 5 are respectively slidably connected to the surface of the switching turntable seat 4 and are equidistantly arranged; the synchronous driving assembly 6 includes an external driving mechanism 61 and an internal driving mechanism 62. Among them, the external driving mechanism 61 is arranged on the surface of the secondary mounting frame 2 and is connected to the switching turntable seat 4, and the internal driving mechanism 62 is arranged on the inner wall of the conical paint coating box 3 and is connected to the external driving mechanism 61, and the paint spraying head 7 is fixedly connected to the surface of the internal driving mechanism 62; the enameled wire 8 sequentially passes through the bottom of the main mounting frame 1, the inside of the conical paint coating box 3, and the inside of the suspension mold 5 corresponding to its position from bottom to top.

[0029] It should be noted that a discharge pipe is provided at the bottom of the conical paint coating box 3 described in this embodiment, and a valve is provided on the discharge pipe.

[0030] Specifically, during use, the enameled wire 8 is sequentially passed through the bottom of the main mounting frame 1, the inside of the conical paint coating box 3, and the inside of the suspension mold 5 corresponding to its position. Then, paint is injected into the paint spraying head 7 through the paint injection end 71. The paint is sprayed by the paint spraying head 7 on the surface of the enameled wire 8 located inside the conical paint coating box 3. During the conveying process of the enameled wire 8, after the thickness of the paint on its surface is processed by the suspension mold 5, the paint is evenly distributed on the surface of the enameled wire 8 and has a uniform thickness. When painting enameled wires 8 with different outer diameters, it is necessary to switch the suspension mold 5 and change the distance between the paint spraying head 7 and the enameled wire 8. The synchronous driving assembly 6 is operated, and the synchronous driving assembly 6 operates to synchronously drive the switching turntable seat 4 to rotate and synchronously drive the paint spraying head 7 to move. The switching turntable seat 4 rotates to switch the suspension molds 5 with different inner diameters to adapt to the painting requirements of enameled wires 8 with different outer diameters. The paint spraying head 7 moves to adjust the paint supply amount by changing the spraying distance to adapt to the painting requirements of enameled wires 8 with different outer diameters. After the suspension mold 5 is adjusted, the replaced enameled wire 8 is passed through the inside of the switched suspension mold 5, and then the enameled wire 8 is continuously conveyed to achieve the painting operation.

[0031] In an embodiment of the present invention, as Figures 2 - 3As shown in the figure, U-shaped grooves 41 are evenly formed on the surface of the switching turntable base 4. Adhesive tapes 42 are respectively arranged at the outer ports of multiple groups of U-shaped grooves 41 and are fixedly bonded to the surface of the switching turntable base 4. Multiple groups of floating molds 5 are respectively slidably connected to the inner walls of multiple groups of U-shaped grooves 41. Step portions 51 are respectively arranged on the surfaces of multiple groups of floating molds 5, and the step portions 51 are slidably connected to the inner walls of the U-shaped grooves 41. Mold cavities 52 are respectively formed inside multiple groups of floating molds 5. The cross-section of the mold cavity 52 is conical, and the inner diameter sizes of the mold cavities 52 in multiple groups of floating molds 5 are different. The inner diameters of the mold cavities 52 in multiple groups of floating molds 5 are adapted to enameled wires 8 with different outer diameters.

[0032] Specifically, the U-shaped grooves 41 and the step portions 51 are provided to facilitate the floating of the floating molds 5. The adhesive tapes 42 are provided to prevent the floating molds 5 from falling off from the U-shaped grooves 41 when switching the floating molds 5. Multiple groups of floating molds 5 are provided, and the inner diameter sizes of the inner mold cavities 52 are different, which is convenient for adapting to enameled wires 8 with different outer diameters. The integrated design eliminates the need for repeated disassembly and assembly operations, effectively improving the work efficiency. By setting the floating molds 5 with corresponding weights, the impact force exerted on the floating molds 5 by the enameled wires 8 is offset by the self-gravity of the floating molds 5, that is, it is ensured that during the working state of the floating molds 5, the step portions 51 thereof can freely float along the inner walls of the U-shaped grooves 41 and will not be in mutual contact with the surface of the switching turntable base 4 due to excessive impact force. After the floating molds 5 float, the jumping and offset of the enameled wires 8 can drive the floating molds 5 to move freely in the U-shaped grooves 41, so that the enameled wires 8 can pass straight through the centers of the mold cavities 52, effectively avoiding uneven film thickness and having good use effects.

The worm 615 is connected to the internal drive mechanism 62.

[0036] Specifically, further explain the structure and connection relationship of the external drive mechanism 61. During use, turn the adjustment handle 613. The rotation of the adjustment handle 613 synchronously drives the rotation of the active gear 612, the synchronous shaft rod 614, and the worm 615.

The rectangular sliding seat 623 is threadedly connected to the outer surface of the threaded lead screw 622 and is slidably connected to the inner wall of the U-shaped fixed seat 621. One end of the threaded lead screw 622 penetrates outside the U-shaped fixed seat 621 and is fixedly connected with a worm gear 624. The worm gear 624 is located on one side of the worm 615 and meshes with each other. The paint spraying head 7 is fixedly connected to the surface of the rectangular sliding seat 623 and is arranged towards the direction of the enameled wire 8. The paint spraying head 7 is connected to the paint injection end 71 fixedly connected to the top of the conical painting tank 3 through a pipeline.

[0038] Specifically, further explain the structure and connection relationship of the internal drive mechanism 62.
