[0002] Electromagnetic wire, also known as winding wire, is an insulated wire used to manufacture coils or windings in electrical products.

[0047] The wind force weakening device comprises: a plurality of baffles 6 , a first moving member 7 , a second moving member 8 , an inclined plate 9 and an electric push rod 10 .

[0048] Specifically, multiple groups of baffles 6 are arranged above the heating cover 2, and the lower ends of the multiple groups of baffles 6 are rotatably connected to the heating cover 2, and the surfaces of the multiple groups of baffles 6 are provided with first slide grooves; the first moving member 7 is composed of a moving plate and multiple groups of first cylindrical pins, and the surface of the moving plate is connected to the multiple groups of first cylindrical pins; the first cylindrical pin is arranged in the first slide groove, and is slidably connected to the baffle 6 through the first slide groove.

[0049] The electric push rod 10 is adjusted so that the output end of the electric push rod 10 pushes the inclined plate 9 to move upward. The inclined plate 9 can slide between the second slide groove and the second cylindrical pin to make the second movable member 8 move horizontally outward. The second movable member 8 drives the first movable member 7 to move. The first movable member 7 can slide between the first cylindrical pin and the first slide groove to make the multiple groups of baffles 6 rotate outward along the connection with the heating cover 2, thereby changing the blowing direction of the hot air and extending the moving distance of the hot air. This method can quickly transfer heat to the internal space of the drying box shell. At the same time, the hot air will damage the wind force during the blowing process, thereby achieving the purpose of reducing the wind force while ensuring the flow of heat, thereby ensuring the flatness of the insulating film.

[0050] The electromagnetic wire paint drying and curing device also includes: two groups of air guide plates 19; the two groups of air guide plates 19 are arranged above the wind weakening device to further reduce the blowing force of the hot air.

[0051] When drying, cold air needs to be drawn in from the outside to heat and transport it to the electromagnetic wire. This drying method has low heating efficiency and cannot reuse the hot air above the electromagnetic wire.

[0055] During the drying process, a large amount of water vapor will be generated, which will reduce the drying efficiency and make it inconvenient to use.

The model of the dust conveying pump 21 is selected according to actual needs and meets the working conditions; the stainless steel filter 13 is arranged inside the hot air collection hood 11 and is located below the output end of the dust conveying pump 21. The hole size on the stainless steel filter 13 is smaller than the size of the desiccant powder, so that the desiccant powder will not fall below.

[0059] The desiccant powder in the dust storage box 20 is extracted by the dust delivery pump 21 and sent to the stainless steel filter 13, so that when the hot air passes through the stainless steel filter 13, the water vapor will be absorbed by the desiccant powder, thereby achieving separation of the water vapor.

[0060] The desiccant powder that falls on the stainless steel filter screen 13 will be piled up and cannot be fully contacted with the hot air, so the filtering efficiency of water vapor is low.

[0061] In order to solve the above problems, an implementation method of this embodiment is proposed, and the electromagnetic wire paint drying and curing device also includes: two sets of flattening devices; the two sets of flattening devices are symmetrically arranged on both sides of the hot air collection hood 11, and are used to flatten the desiccant powder on the stainless steel filter mesh 13.

[0062] Each set of paving devices includes: a screw rod 17 , a second motor 18 , a nut 16 , a cross plate 15 and a brush head 14 .

[0063] Among them, the screw 17 is arranged on the upper part of the interior of the drying box shell 1; the output end of the second motor 18 is connected to the screw 17, which is used to drive the screw 17 to rotate. The model of the second motor 18 is selected according to actual needs and meets the working conditions; the nut 16 is threadedly connected to the screw 17, and when the screw 17 rotates, the nut 16 will move horizontally; the cross plate 15 is arranged above the nut 16 and connected to the nut 16, and the nut 16 drives the cross plate 15 to move.

[0064] The second motor 18 is started, and the output end of the second motor 18 drives the screw 17 to rotate. The screw 17 causes the nut 16 to move horizontally toward the middle. The nut 16 drives the cross plate 15 to move. The cross plate 15 also drives the brush head 14 to move. The brush head 14 flattens the desiccant powder accumulated on the stainless steel filter 13, so that the desiccant powder can be evenly contacted with the hot air, thereby improving the filtration of water vapor.

[0065] The electromagnetic wire paint drying and curing device further comprises: a box door 22 ; the box door 22 is arranged on the drying box shell 1 .

[0066] Working principle:

[0067] When the electromagnetic wire paint drying and curing device is in use, first, the user passes a plurality of electromagnetic wires through the drying box shell 1, and as the electromagnetic wires move, the electric heating plate 5 is started, and the electric heating plate 5 heats the air inside the heating cover 2, and at the same time, the first motor 4 is started, and the output end of the first motor 4 drives the fan blades 3 to rotate, and the fan blades 3 blow hot air onto the electromagnetic wires to dry the electromagnetic wires. In this process, the electric push rod 10 is adjusted so that the output end of the electric push rod 10 pushes the inclined plate 9 to move upward, and the inclined plate 9 slides between the second slide groove and the second cylindrical pin, so that the second moving member 8 moves horizontally outward, and the second moving member 8 drives the first moving member 7 to move, and the first moving member 7 slides between the first cylindrical pin and the first slide groove, so that the plurality of baffles 6 rotate outward along the connection with the heating cover 2, thereby changing the blowing direction of the hot air, that is, increasing the heat transfer efficiency, and the hot air will damage the wind force during the blowing process, thereby achieving the goal of reducing the heat flow while ensuring the heat flow. The purpose of low wind force is to ensure the flatness of the insulating film. When the hot air blows onto the air guide plate 19, the air guide plate 19 further reduces the blowing force of the hot air. The hot air that has completed drying will be collected by the hot air collection hood 11 and sent back to the heating hood 2 through the heat circulation pipe 12. When the hot air passes through the stainless steel filter 13, the dust conveying pump 21 is started. The dust conveying pump 21 extracts the desiccant powder in the dust storage box 20 and sends it to the stainless steel filter 13, so that when the hot air passes through the stainless steel filter 13, the water vapor will be absorbed by the desiccant powder to achieve the separation of water vapor. Then the second motor 18 is started, and the output end of the second motor 18 drives the screw 17 to rotate. The screw 17 will move the nut 16 horizontally to the middle, and the nut 16 drives the cross plate 15 to move. The cross plate 15 also drives the brush head 14 to move. The brush head 14 will flatten the desiccant powder accumulated on the stainless steel filter 13, so that the desiccant powder can be evenly contacted with the hot air, thereby improving the filtration of water vapor and completing the use of this device.
