Abstract
Description
Technical Field
[0001] The utility model relates to the field of enameled wire production, in particular to an enameling device for enameled wire. Background Art
[0002] Enameled wire is a main variety of winding wire and is the main raw material for products such as motors, electrical appliances, and household appliances. It consists of two parts, a conductor and an insulating layer. After the bare wire is annealed and softened, it is coated with paint multiple times and then dried.
[0003] In the existing enameling device for enameled wire, the enameled wire is in a horizontal state before entering the drying device. At this time, the paint liquid has not solidified, and the paint liquid will move downward under the influence of gravity, resulting in uneven paint surface of the enameled wire. Content of the Utility Model
[0004] The utility model provides an enameling device for enameled wire to solve the above technical deficiencies, so that the enameled wire is in a vertical state when leaving the paint liquid and entering the drying device, ensuring the uniformity of the paint surface.

A second guide wheel is provided in the enameling tank below the first guide wheel. A third guide wheel is provided in the enameling tank on the side of the second guide wheel away from the first guide wheel. A paint scraping device is provided in the enameling tank above the third guide wheel. The paint scraping device is divided into two parts. The lower half of the paint scraping device is a cylindrical barrel, and the upper half is a hollow cone. A paint scraping opening is vertically penetrated at the top of the hollow cone of the paint scraping device. A drying box is provided outside the enameling tank above the paint scraping device. A drying device is provided in the drying box. An inlet and an outlet are provided at the bottom of the drying box. The inlet is directly opposite to the paint scraping device. A fourth guide wheel is provided in the drying box above the inlet. The vertical height of the fourth guide wheel from the bottom of the drying box is not less than 3m. A number of fifth guide wheels are provided inside the drying box. The fifth guide wheels are arranged in a staggered manner in the vertical direction. A sixth guide wheel is provided below the outlet.
[0006] A number of air holes are provided on the side surface of the top hollow cone of the paint scraping device.
[0007] The circumferential surfaces of the first guide wheel, the second guide wheel, the third guide wheel, the fourth guide wheel, the fifth guide wheel, and the sixth guide wheel form a V-shaped concave structure inward.
[0008] The enameling device for enameled wire obtained by the utility model has an integrated setting of enameling and drying, reducing production costs. At the same time, the enameled wire is in a vertical state before the paint surface solidifies, reducing the influence of gravity on the paint surface and making the paint surface of the enameled wire more uniform. Description of the Drawings
[0009] Figure 1 is the structural schematic diagram of the present utility model;
[0010] Figure 2 is the paint scraping device;
[0011] Figure 3 is the first guide wheel. Specific embodiments
[0012] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, detail the specific embodiments, structures, features and their effects of the present utility model as follows.
[0013] Embodiment 1:
[0014] Such as Figures 1-3As shown in the figure, the utility model discloses a painting device for enameled wire, which includes a painting pool 1 filled with paint liquid. The paint liquid submerges the lower half of the second guide wheel 3, the third guide wheel 4 and the paint scraping device 5. On the upper side of one end of the painting pool 1, there is a first guide wheel 2. The first guide wheel 2 serves as the input end to introduce the copper wire into the paint liquid in the painting pool. In the axial direction of the painting pool 1 below the first guide wheel 2, there is a second guide wheel 3. Inside the painting pool 1 on the side of the second guide wheel 3 away from the first guide wheel 2, there is a third guide wheel 4 to ensure that the enameled wire is soaked in the paint liquid for sufficient time, making the paint liquid attached to the copper wire more sufficient and uniform. Inside the painting pool 1 above the third guide wheel 4, there is a vertically arranged paint scraping device 5. The third guide wheel 4 guides the copper wire to the paint scraping device 5, making the copper wire in a vertical state to reduce the influence of gravity on the paint liquid. The paint scraping device 5 is divided into two parts. The lower half of the paint scraping device 5 is a cylindrical barrel to keep the internal paint liquid stable, and the upper half is a hollow cone. At the top of the hollow cone of the paint scraping device 5, there is a vertically penetrating paint scraping opening 51. The diameter of the paint scraping opening 51 is larger than the diameter of the copper wire. The copper wire enters from below the paint scraping device 5 and leaves from the paint scraping opening 51. The copper wire scrapes off the excess paint liquid on its surface through the paint scraping opening 51. Above the paint scraping device 5 in the painting pool 1, there is a drying oven 6 to cure the paint surface of the enameled wire. Inside the drying oven 6, there is a drying device 7 which is a heating plate and is a known product in the prior art. At the bottom side of the drying oven 6, there are a feeding port 61 and a discharging port 62. The copper wire enters the drying oven 6 through the feeding port 61 for drying and leaves from the discharging port 62. The feeding port 61 is directly opposite to the paint scraping device 5, and the third guide wheel 4, the fourth guide wheel 8 and the paint scraping device 5 are in the same vertical direction, that is, the copper wire output from the third guide wheel 4 passes through the paint scraping opening 51 of the paint scraping device 5, enters the interior of the drying oven 6 through the feeding port 61, and bypasses the fifth guide wheel 8. During this process, the copper wire is always in a vertical state. The enameled wire with the excess paint surface scraped off by the paint scraping device 5 enters the drying oven 6 in a vertical state through the feeding port 61. Above the feeding port 61 in the drying device 7, there is a fourth guide wheel 8. The vertical height between the fourth guide wheel 8 and the bottom side of the drying oven 6 is not less than 3m to ensure that the enameled wire is in a vertical state during the curing of the paint surface, reduce the influence of gravity on the paint liquid, and make the paint surface more uniform. Inside the drying oven 6, there are several fifth guide wheels 9 which are arranged in a staggered manner in the vertical direction. The enameled wire bypasses the fifth guide wheels 9. Below the discharging port 62, there is a sixth guide wheel 10. The enameled wire bypasses the fourth guide wheel 8 and the fifth guide wheels 9 in the drying oven 6 for sufficient drying, leaves from the discharging port 62, and finally the sixth guide wheel 10 guides the enameled wire to the winding position.
[0015] The drying oven 6 above the painting pool 1 can be fixed by brackets to keep the relative positions of the painting pool 1 and the drying oven 6 unchanged.
[0016] A number of ventilation holes 52 are provided on the side of the hollow conical body at the top of the paint scraping device 5 to balance the air pressure inside and outside the paint scraping device 5, so that the paint surface inside the paint scraping device 5 remains stable.
[0017] The circumferential surfaces of the first guide wheel 2, the second guide wheel 3, the third guide wheel 4, the fourth guide wheel 8, the fifth guide wheel 9 and the sixth guide wheel 10 form a V-shaped concave structure inward to limit the enameled wire.
