Description

Technical Field

[0001] This utility model belongs to the technical field, and specifically relates to a device for rapid cooling of varnish during the production of winding wires. Background Technology

[0002] In the production of winding wires, the winding wires are usually drawn, followed by insulation treatment using a winding impregnation method. Because the drawing process generates a large amount of heat, the temperature of the varnish can easily rise during impregnation, affecting the effectiveness of the impregnation process. Therefore, cooling treatment is necessary for the varnish.

[0003] Existing rapid cooling devices for varnish during winding wire production, while meeting the basic requirement of cooling the varnish, typically rely on a static cooling structure. This results in insufficient cooling effect, with the cooling effect decreasing the further away from the cooling structure, leading to significant temperature differences in different areas of the varnish and thus failing to fully meet user needs. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a rapid cooling device for varnish during winding wire production. This device not only meets the basic requirements for cooling varnish but also effectively and efficiently cools the varnish through a stirring structure.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a rapid cooling device for varnish during winding wire production, comprising a storage tank for storing varnish, a spiral cooling pipe installed in the storage tank, an inlet pipe connected to the upper end of the cooling pipe installed at the upper side of the storage tank, an outlet pipe connected to the cooling pipe installed at the lower side of the storage tank, multiple temperature sensors installed at the side of the storage tank, a horizontal plate installed at the top of the storage tank, a rotating agitator module installed in the middle of the horizontal plate, and a lifting agitator module installed at the side of the horizontal plate. Through the multiple temperature sensors, the temperature of the varnish in different areas can be monitored in real time. When the temperature of the varnish in different areas is found to be the same, it indicates that the varnish in the storage tank has been sufficiently and uniformly cooled.

[0006] As a further improvement of this utility model, the rotary stirring module includes a stirring shaft that runs vertically through and is rotatably connected to the horizontal plate, and stirring blades are provided on the side end of the stirring shaft.

[0007] As a further improvement of this utility model, the lifting agitator module includes an agitator rod that runs vertically through and slides on a horizontal plate. An agitator ring plate is mounted on the agitator rod and sleeved on the outside of the cooling pipe. The agitator ring plate has a clearance notch that is misaligned with the inlet and outlet pipes. The clearance notch on the agitator ring plate is misaligned with the inlet and outlet pipes, thus avoiding interference with the inlet and outlet of the cooling pipes during agitation.

[0008] As a further improvement of this utility model, a fixing plate is provided at the upper end of the stirring rod, a spiral sleeve is fixedly connected to the bottom of the fixing plate, and a spiral rod is provided at the upper end of the stirring shaft and screwed to the spiral sleeve.

[0009] As a further improvement of this utility model, a telescopic push rod is also vertically arranged on the horizontal plate, and the output shaft of the telescopic push rod is connected to the fixed plate.

[0010] As a further improvement of this utility model, the horizontal plate is rotatably connected to the agitator shaft via a bearing. This rotatable connection between the agitator shaft and the horizontal plate ensures smooth rotation.

[0011] As a further improvement of this utility model, a connecting groove is provided through the horizontal plate, and the stirring shaft is vertically slidably connected to the connecting slot. The stirring shaft and the horizontal plate can be vertically adjusted through the connecting groove, which enhances the flexibility of the device.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Firstly, the spiral cooling pipe design increases the contact area between the cooling medium and the paint, thereby improving the heat exchange efficiency. The upper end of the cooling pipe is connected through the liquid inlet pipe, and the lower end is connected through the liquid outlet pipe, forming a circulating cooling system. The paint inside the cooling pipe can be agitated by a rotating agitator module, and the paint outside the cooling pipe can be agitated by a lifting agitator module, ensuring that the paint can be cooled evenly.

[0014] Secondly, the stirring shaft and stirring blades can drive the paint liquid to rotate and flow, so that the paint liquid can fully contact the outer wall of the cooling pipe and accelerate the cooling speed; the stirring rod and stirring ring plate can move in the vertical direction, further enhancing the mixing effect of the paint liquid and avoiding excessive local temperature difference.

[0015] Third, the spiral sleeve at the bottom of the fixed plate is screwed to the spiral rod at the upper end of the stirring shaft, realizing the linkage between the stirring rod and the stirring shaft. This design not only simplifies the operation process, but also ensures the coordination and stability of the stirring process. Attached Figure Description

Detailed Implementation

[0022] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0023] like Figure 1 , 2 As shown in Figure 3, a rapid cooling device for varnish during winding wire production includes a varnish storage tank 101. A spiral cooling pipe 102 is fixed to the varnish storage tank 101 via a fixing rod 103. An inlet pipe 104 connected to the upper end of the cooling pipe 102 is provided on the upper side of the varnish storage tank 101, and an outlet pipe 105 connected to the cooling pipe 102 is provided on the lower side of the varnish storage tank 101. Multiple temperature sensors 106 are provided on the side of the varnish storage tank 101. A horizontal plate 107 is provided on the top of the varnish storage tank 101, a rotating agitator module is provided in the middle of the horizontal plate 107, and a lifting agitator module is provided on the side of the horizontal plate 107. Through the multiple temperature sensors 106, the temperature of the varnish in different areas can be monitored in real time. When the temperature of the varnish in different areas is found to be the same, it indicates that the varnish in the varnish storage tank 101 has been sufficiently and uniformly cooled.

[0024] like Figure 1As shown, the rotary agitation module includes an agitation shaft 201 that is vertically connected to and rotatably connected to the horizontal plate 107, and agitation blades 202 are provided on the side end of the agitation shaft 201.

[0025] like Figure 1 , 2 As shown, the lifting agitator module includes an agitator rod 301 that runs vertically through and slides on the horizontal plate 107. An agitator ring plate 302 is provided on the agitator rod 301 and is sleeved on the outside of the cooling pipe 102. The agitator ring plate 302 is provided with a clearance notch 303 that is misaligned with the liquid inlet pipe 104 and the liquid outlet pipe 105.

[0026] Cooling medium (such as cooling water or refrigerant) enters the spiral cooling pipe 102 in the liquid storage tank 101 through the liquid inlet pipe 104. The cooling medium flows in from the upper end of the cooling pipe 102, and after passing through the spiral path, it flows out from the lower end of the cooling pipe 102 through the liquid outlet pipe 105, forming a circulating cooling system. The paint liquid in the storage tank 101 comes into contact with the outer wall of the cooling pipe 102, achieving initial cooling through heat exchange. A temperature sensor 106 monitors the temperature changes of the paint liquid in different areas in real time. The stirring shaft 201 is driven to rotate, thereby causing the stirring blade 202 to start rotating, which in turn causes the paint liquid inside and around the cooling pipe 102 to flow, making full contact between the paint liquid and the outer wall of the cooling pipe 102 and accelerating the cooling speed. The stirring rod 301 is driven to move vertically up and down, causing the stirring ring plate 302 to stir vertically. The clearance notch 303 on it is staggered with the inlet pipe 104 and the outlet pipe 105 to avoid interference with the inlet and outlet of the cooling pipe 102. The lifting and stirring enhances the mixing effect of the paint liquid and further eliminates local temperature differences.

[0027] Temperature sensor 106 continuously monitors the temperature changes of different areas of the paint liquid; when it is found that the paint liquid temperature is the same in different areas, it indicates that the paint liquid has reached a state of sufficient and uniform cooling and the cooling process is complete.

[0028] According to another embodiment of the present invention, such as Figure 4 As shown, a fixing plate 304 is also provided at the upper end of the stirring rod 301, and a spiral sleeve 305 is fixedly connected to the bottom of the fixing plate 304. A spiral rod 306, which is screwed to the spiral sleeve 305, is provided at the upper end of the stirring shaft 201. During the vertical movement of the stirring rod 301, it can also drive the fixing plate 304 and the spiral sleeve 305 to move vertically up and down. Because the spiral sleeve 305 is screwed to the spiral rod 306, the spiral sleeve 305 can drive the stirring shaft 201 and the stirring blade 202 to rotate during the vertical movement. This realizes the linkage between the stirring rod 301 and the stirring shaft 201. Through this linkage design, it is ensured that the rotary stirring module and the lifting stirring module work together to improve the stirring efficiency.

[0029] According to another embodiment of the present invention, such as Figure 4 As shown, a telescopic push rod 307 is also vertically arranged on the horizontal plate 107, and the output shaft of the telescopic push rod 307 is connected to the fixed plate 304. By simply driving the output shaft of the telescopic push rod 307 to extend or shorten vertically by a certain length, the fixed plate 304 can be driven to move vertically up and down.

[0030] According to another embodiment of the present invention, such as Figure 1 , 4 As shown, the horizontal plate 107 is rotatably connected to the stirring shaft 201 via a bearing 203. The outer ring of the bearing 203 is connected to the fixed plate 304, and the inner ring of the bearing 203 is connected to the outer wall of the stirring shaft 201. The rotatable connection between the stirring shaft 201 and the horizontal plate 107 via the bearing 203 ensures the smoothness of rotation.

[0031] According to another embodiment of the present invention, such as Figure 1 , 4 As shown, a connecting groove 308 is provided through the horizontal plate 107, and the stirring shaft 201 is vertically slidably connected to the connecting groove. The vertical sliding cooperation between the stirring shaft 201 and the connecting groove 308 enables the stirring rod 301 to move vertically up and down relative to the horizontal plate 107, and can prevent the telescopic push rod 307 from being easily deformed and damaged by non-vertical forces.

[0032] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
