Problems solved by technology

In the traditional technology, the cooling device of the fixed speed wheel of the high-speed enamelling machine adopts natural wind or strong wind for cooling. However, with this cooling method, the temperature of the fixed speed wheel is as high as 135°C, and the surface temperature of the finished enameled wire produced is as high as 61°C. The cooling effect of the enameled wire is not good. Good, its outer paint film is easily scratched, resulting in poor performance
In view of the above situation, in order to ensure the heat exchange effect between the enameled wire and the fixed speed wheel, some manufacturers can only reduce the running speed of the fixed speed wheel to ensure that the enameled wire has more time to exchange heat with the fixed speed wheel, but this is greatly reduced. The DV value of the product (unit capacity) is affected, which affects the production efficiency

Embodiment 1

[0031] See attached image 3 and Figure 4 As shown, the high-speed enamelling machine fixed speed wheel 101 cooling device of the present invention includes a fixed speed wheel 101 and a rotary joint 102, and the fixed speed wheel 101 includes an inner tube 1 and an outer tube 2, and the outer tube 2 and the inner tube 1 are mostly used A rolled steel pipe or an aluminum pipe with better thermal conductivity is preferred, and the outer pipe 2 is sleeved on the inner pipe 1 by setting positioning ends at both ends thereof. One end wall of the outer tube 2 has a water inlet 21, and the other end has a water outlet 22. When in use, because the fixed speed wheel 101 drives the enameled wire to rotate, therefore, the water inlet 21 and the water outlet 22 places should be equipped with Rotary joint 102, the structure of this type of rotary joint 102 is specifically figure 2 As shown and explained above, one end of the rotary joint 102 can rotate with the fixed wheel 101, and th...

Embodiment 2

[0033] see Figure 5 , Image 6 As shown, the present embodiment is another embodiment of the fixed speed wheel 101 of the high-speed enamelling machine according to the present invention, and its basic structure is consistent with that of the first embodiment, so it is omitted here. The difference is:

[0034] The inner wall of the outer tube 2 is provided with a circular arc groove 23 matching the heat exchange tube 4, and the heat exchange tube 4 is embedded in the circular arc groove 23, which can realize a better fit of the heat exchange tube 4 in the heat exchange cavity 3. Positioning can also increase the contact surface between the heat exchange tube 4 and the outer tube 2 and improve the heat exchange efficiency. At the same time, heat-conducting silicone grease is provided between the arc groove 23 and the wall of the heat exchange tube 4, which further improves the heat exchange efficiency of the heat exchange tube 4 through the tube wall of the outer tube 2 and t...

Embodiment 3

[0036] see Figure 7 , Figure 8 As shown, the present embodiment is the third embodiment of the fixed speed wheel 101 of the high-speed enamelling machine according to the present invention, and its basic structure is consistent with that of Embodiment 1, so it is omitted here. The difference is:

[0037] The heat exchange tube 4 is serpentinely wound on the outer wall of the inner tube 1, so that the water flow flows back and forth from the surface of the inner tube 1 along the axial direction to the two end walls of the tube, and also makes the heat exchange tube 4 communicate with the enameled wire through the outer tube 2. Better heat exchange effect.

Abstract

The invention discloses a cooling device for the speed fixer wheel of a high speed enamelling machine. The invention comprises a speed fixer wheel which is composed of an inner tube and an outer tube; the outer tube is hitched on the outer tube; a water inlet is arranged on the wall at one end of the outer tube and an water outlet is arranged at the other end. The room between the outer wall of the inner tube and the inner wall of the outer tube makes up a heat exchange cavum. The cooling device is characterized in that a heat exchanger tube is arranged in the heat exchanger cavum and is wound on the outer wall of the inner tube. One end of the heat exchange tube is in tight communication with the water inlet and the other end is in tight communication with the water outlet. Two ends of the speed fixer wheel are respectively provided with revolving joints which are in abutting joint with the water inlet or the water outlet so that the water inlet, the heat exchange tube, the water outlet and the two revolving joints are communicated, forming a current passage. The cooling device for the speed fixer wheel of the high speed enamelling machine is good in cooling effect and is good for improving production efficiency.

Description

technical field [0001] The invention relates to a cooling device for a fixed-speed wheel of a high-speed enamelling machine, which belongs to a special device for cooling the fixed-speed wheel of an enamelling machine in the enamelled wire industry, and is used for cooling the enameled wire after the enamelling process. Background technique [0002] In the existing high-speed enameled wire manufacturing industry, after the enameled wire passes through the high-temperature enameling process, the output end needs to be cooled. In this cooling process, the enameled wire is often cooled by a fixed speed wheel cooling device. In the traditional technology, the cooling device of the fixed speed wheel of the high-speed enamelling machine adopts natural wind or strong wind for cooling. However, with this cooling method, the temperature of the fixed speed wheel is as high as 135°C, and the surface temperature of the finished enameled wire produced is as high as 61°C. The cooling effec...
