[0027] Example 1:

[0028] See Figure 1-Figure 5The present invention provides a guide wheel cooling device for a wire drawing machine, comprising a guide wheel body 1, wherein the outer circumference of the guide wheel body 1 is provided with two guide wheel grooves 11, the guide wheel groove 11 is annular and concave, for allowing the wire to pass through. The guide wheel body 1 comprises a connecting portion 12 and an outer ring body 13 coaxially arranged with the connecting portion 12, and a connecting through hole is provided in the center of the outer ring body 13, which is used to rotatably fix the guide wheel body 1 on the wire drawing machine. The connecting portion 12 and the outer ring body 13 are fixedly connected by a plurality of connecting arms 14. The outer ring body 13 is provided with a plurality of first heat dissipation grooves 131, one end of the first heat dissipation groove 131 extends to the bottom of the guide wheel groove 11, and the other end is provided on the inner ring of the guide wheel body 1, and an air guide blade 15 for cooperating with the first heat dissipation groove 131 is provided on the inner ring of the guide wheel body 1 near the first heat dissipation groove 131. The air guide blade 15 is used to guide the airflow into the first heat dissipation groove 131 when the guide wheel body 1 rotates. In this embodiment, by providing a first heat dissipation groove 131 connected to the guide wheel groove 11 on the guide wheel body 1, the heat dissipation effect of the guide wheel groove 11 can be improved, and heat accumulation in the guide wheel groove 11 that is directly in contact with the wire material can be avoided. By providing an air guide blade 15 to cooperate with the first heat dissipation groove 131, the air flow can be introduced into the first heat dissipation groove 131 and input into the guide wheel groove 11 through the first heat dissipation groove 131 when the guide wheel body 1 rotates, which can actively dissipate heat and cool down, improve the cooling effect, and ensure that the guide wheel body 1 can still maintain a low temperature during long-term operation. The guide wheel body 1 has its own cooling structure, and there is no need to provide other cooling mechanisms. The structure is simpler and the cost is lower.

[0029] Specifically, a chamfer is provided at an opening of one end of the first heat dissipation groove 131 close to the guide wheel groove 11, so as to avoid damaging the wire.

[0030] See Figure 3 The first heat dissipation slot 131 is tilted relative to the radial line of the guide wheel body 1. When the guide wheel body 1 rotates, its rotation direction corresponds to the setting direction of the first heat dissipation slot 131, which facilitates the airflow to be introduced into the first heat dissipation slot 131.

[0031] Specifically, in order to improve strength, the connecting portion 12 , the outer ring body 13 , and the connecting arm 14 are integrally formed.

[0032] Example 2:

[0033] Based on the first embodiment, the connecting arms 14 are a plurality of fan blades arranged in an annular array between the connecting portion 12 and the outer ring body 13. When the guide wheel body 1 rotates, the fan blades are used to direct air from one side of the guide wheel body 1 to the other side. Configuring the connecting arms 14 as fan blades can enhance air circulation when the guide wheel body 1 rotates, further improving the heat dissipation effect.

[0034] See Figure 1 、 Figure 2 、 Figure 4 A partition block 16 is provided between adjacent guide wheel grooves 11. A second heat dissipation channel 161 is provided within the partition block 16. One end of the second heat dissipation channel 161 extends to the outer peripheral wall of the partition block 16 and the other end extends to the inner ring of the outer ring body 13. The second heat dissipation channel 161 can guide air between the guide wheel grooves 11, further enhancing the heat dissipation effect.

[0035] Example 3:

[0036] When air cooling cannot meet the needs, refer to Figure 6 、 Figure 7 In this embodiment, the guide wheel body 1 is also provided with a liquid cooling mechanism. The liquid cooling mechanism includes a plurality of liquid cooling channels 17 evenly distributed within the guide wheel body 1. A connecting hole is centrally located within the connecting portion 12, and a support shaft 18 is connected thereto. The support shaft 18 includes a liquid inlet channel 181 and a liquid outlet channel 182 arranged along its axial direction. One end of the liquid inlet channel 181 is connected to the input end of the liquid cooling channel 17, and the other end is connected to the output end of the liquid cooling source. The liquid cooling channel 17 is connected to the output end of the liquid cooling channel 17, and the other end is connected to the input end of the liquid cooling source. The provision of the liquid cooling mechanism in this embodiment allows a low-temperature liquid cooling medium to be introduced into the liquid cooling channels 17 within the guide wheel body 1, thereby reducing the temperature of the guide wheel body 1 and achieving a more effective cooling effect.

[0037] See Figure 7 The guide wheel body 1 is rotatably connected to the support shaft 18. In order to ensure that the medium can be normally input into the liquid cooling channel 17, the inner wall of the connection hole is respectively provided with an annular liquid inlet cavity 171 and an annular liquid outlet cavity 172 that are connected to the input end of the liquid cooling channel 17. The side wall of the support shaft 18 is provided with a liquid inlet side port 183 that cooperates with the annular liquid inlet cavity 171 and a liquid outlet side port 184 that cooperates with the annular liquid outlet cavity 172. The liquid inlet side port 183 and the liquid outlet side port 184 are respectively connected to the liquid inlet channel 181 and the liquid outlet channel 182. When the guide wheel body 1 rotates relative to the support shaft 18, the annular liquid inlet cavity 171 and the annular liquid outlet cavity 172 can always remain connected to the liquid inlet side port 183 and the liquid outlet side port 184, so that the guide wheel body 1 can also perform liquid cooling normally during rotation.

[0038] See Figure 7 Three rotating sealing rings 19 are provided between the connecting hole and the supporting shaft 18 , which are used for sealing the annular liquid inlet cavity 171 and the annular liquid outlet cavity 172 , respectively.

[0039] Working process of the present invention:

[0040] During the operation of the guide wheel cooling device for a wire drawing machine of the present invention, glass fiber can pass through the guide wheel groove 11. When the guide wheel body 1 rotates, the air guide blades 15 cooperate with the first heat dissipation groove 131, and can guide the airflow into the first heat dissipation groove 131 and input the airflow into the guide wheel groove 11 through the first heat dissipation groove 131 when the guide wheel body 1 rotates. It can actively dissipate heat and reduce temperature, improve the cooling effect, and ensure that the guide wheel body 1 can still maintain a low temperature during long-term operation.
