Description
Technical Field
The invention belongs to the technical field of enameled wire production, and particularly relates to an enameled wire production coating device.
Background
The enameled wire is a main variety of winding wire and consists of a conductor and an insulating layer, and a bare wire is annealed and softened and then is subjected to painting and baking for multiple times. The processing steps of the bare wire after being drawn into proper thickness are as follows: painting → baking → cooling (returning to the first step of painting until the painting thickness reaches the requirement and then proceeding to the subsequent step) → lubrication → take-up.

That is, when the customer desires to enhance certain effects, such as breakdown voltage, it is necessary to increase the thickness of the wire after coating. At present, attempts to improve certain properties of wire without increasing the thickness of the wire have been largely unachievable.

The invention has the advantage that the breakdown voltage resistance value of the finished enameled wire at room temperature is obviously increased while the coating thickness of the enameled wire is hardly changed.
In order to achieve the purpose, the invention adopts the following technical scheme:

Preferably, the top of the first painting member is provided with a concave part for the wire to pass through, and the concave part is provided with a nozzle communicated with the paint supply part; the nozzle of the second painting part is positioned on the upper side of the wire; a filtrate piece used for scraping off redundant coating liquid on the wire rod is arranged on the rear side of the second painting part along the wire rod conveying direction; the distance between the second painted part and the filtrate part is smaller than the distance between the second painted part and the first painted part.
Preferably, the coating enhancement mechanism further comprises a residual liquid collecting tank, the first painted part and the second painted part are both arranged in the residual liquid collecting tank, the bottom surface of the residual liquid collecting tank is a liquid drainage surface, and a liquid drainage hole for draining redundant coating liquid to the coating supply part is arranged on the liquid drainage surface; and a single wire groove for a wire to pass through is formed in the plate surface on the wire outlet side of the residual liquid collecting groove, and the filtrate piece is fixedly arranged in the single wire groove.
Preferably, the reinforcing coating mechanism is further provided with a cover which covers the coating material supply part, the top surface of the cover is an inclined surface, and the inclined surface is gradually inclined from high to low along the wire conveying direction; the wire outlet side of the inclined surface is close to the drying box, and the drying box is located on the wire outlet side of the reinforcing coating mechanism.
Preferably, a flow guide structure is arranged on the outlet side of the inclined surface, and an outlet of the flow guide structure is arranged towards the outer side of the cover cap and enables the coating liquid sprayed onto the inclined surface to flow to the outside of the cover cap.
Preferably, the device also comprises a cooling mechanism arranged on the wire outlet side of the drying box.
Preferably, the cooling mechanism comprises a frame body, a cover body, a fan, an air pipe and an air outlet, the frame body is a frame-shaped structure formed by the cover body at the upper part and a bottom plate at the lower part, a cooling channel is formed between the cover body and the bottom plate, and the fan is fixedly arranged on the frame body; the air pipe is fixedly arranged in the cooling channel and is positioned below the wire rods, the length direction of the air pipe is vertical to the transmission direction of the wire rods, the air pipe is communicated with the air outlet of the fan (), and the air pipe is arranged near the wire inlet of the frame body; the air outlet is formed in the air pipe facing the air outlet side of the frame body along the length direction of the air pipe; the cooling mechanism further comprises a guide piece which is arranged in the frame body and is positioned below the wire rods, the guide piece is arranged from low to high along the wire rod conveying direction, the bottom end of the guide piece is arranged on the air pipe below the air outlet, and the top end of the guide piece is close to the lower portion of the wire rods.
The invention has the advantages that:
(1) in the existing production of enameled wires, in order to improve the breakdown voltage resistance of the enameled wire, only a technical means of increasing the thickness of the enamel layer of the enameled wire can be adopted. Through continuous research and experiments of workers, the enhanced coating mechanism can obviously improve partial performances of the enameled wire, such as enhanced coated enameled wire is more resistant to breakdown at room temperature, but the thickness of the enameled wire is not increased nearly (see the comparison between table 1 and table 2). The production device effectively improves the performance of the enameled wire and increases the income of enterprises on the basis of simple change.
(2) In the prior art, when a wire is coated, only a first painting part for coating the wire is arranged in the painting step. The reinforcing coating mechanism is additionally provided with a second painting part. In the coating process, the first painting part coats the wire in an upwelling mode from bottom to top, the second painting part coats the wire in a shower coating mode from top to bottom, and finally, the filtrate part filters out redundant paint liquid.
Although only the second painted part is added, the performance of the wire after the enhanced painting is greatly improved because: in the original coating process, after the wire is coated by the first painting part, the first painting part and the filtrate part have a certain distance, so that the wire does not come out from the first painting part and before the filtrate part, paint liquid on the wire slides from top to bottom, the thickness of the paint layer on the wire is slightly different from top to bottom, and the roundness index of the finally-formed enameled wire is poor after the wire is wiped by the filtrate part. According to the invention, the second painting part is additionally arranged, the wire rod is coated again by the second painting part after coming out of the first painting part, and because the second painting part is coated in a curtain coating mode, the curtain coated paint liquid is accumulated above the enameled wire and has a tendency of sliding from top to bottom.
It is also particularly emphasized that the paint liquid on the wire is slightly solidified after the wire comes out of the first painting part, and the slightly solidified paint liquid surface is supplemented by the curtain painting paint liquid after the second painting part is additionally arranged, so that the paint layer finally formed on the surface of the wire has high thickness and roundness indexes and high compactness, and the performance of the enameled wire is obviously improved.
(3) In the reinforced coating mechanism, redundant oil can be instantly returned to a coating material supply part through the use of a residual liquid collecting groove and a liquid discharge surface, and a enameled wire which is not required to be coated again can pass through a single-line groove without a filtrate piece.
(4) When a wire is coated, if it is exposed to air, the coating liquid may be inevitably doped with impurities under the influence of a factory environment, the performance of the wire after coating is affected, and the impurities are also increased by the coating liquid being reflowed. The invention is additionally provided with the cover cap which can isolate impurities, so that the function of isolating impurities can be achieved. The inclined surface arranged on the cover cap enables the coating liquid to flow downwards along the inclined direction of the cover cap, and the phenomenon that a small amount of coating liquid sprayed to the inner top of the cover cap is accumulated and then inversely drips to the wire can be avoided, so that the roundness and the quality of the enameled wire are ensured.
(5) According to the invention, the flow guide structure arranged in the cover cap can guide the coating liquid to the outside of the cover cap, so that the coating liquid is convenient to recover and reuse.
(6) The cooling mechanism in the invention is used for cooling the dried enameled wire. Through the use of the frame body, the cover body, the fan, the air pipe, the guide piece and the air outlet, the enameled wire is continuously in the process of air-blowing cooling in the whole process of passing through the cooling channel. The guide piece can enable wind to blow to the enameled wire in an inclined mode, the area of a blowing opening of the enameled wire blown by the wind is reduced, wind power is concentrated, and the wind speed is higher. The cover body avoids dust falling back above the wires, and meanwhile, the air can be ensured to be blown out of the wire outlet of the frame body all the time, and the cooling effect is good.
