Technical Field

[0001] This utility model relates to the field of post-spinning two-traction motors, specifically to a heat dissipation structure for a post-spinning two-traction motor. Background Technology

[0002] The existing secondary spinning motor has a motor shaft that extends away from the output end, and a fan blade is installed at the extension. When the motor rotates, it drives the fan blade to rotate to cool the secondary spinning motor. However, the vibration generated when the secondary spinning motor rotates can easily damage the fan blade, and the fan blade and the motor will resonate, damaging the motor.

[0003] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Summary of the Invention

[0004] The purpose of this invention is to provide a heat dissipation structure that avoids damage to the motor and fan blades.

[0005] To achieve the above objectives, this utility model adopts the following technical solution:

[0006] A heat dissipation structure for a secondary spinning motor includes a fan arranged coaxially with the secondary spinning motor. The secondary spinning motor and the fan do not contact each other. A ventilation port is provided on the end of the secondary spinning motor that is away from the output shaft of the secondary spinning motor. The ventilation port is connected to the air outlet of the fan through a flexible ventilation component.

[0007] Preferably, the diameter of the air outlet of the fan is greater than or equal to the diameter of the ventilation opening.

[0008] Preferably, the outer side of the housing of the secondary spinning motor has a plurality of grooves arranged around the housing, and one end of the flexible ventilation component fixed to the secondary spinning motor covers each of the grooves.

[0009] Preferably, multiple air ducts are fixed on the outer side of the housing of the secondary spinning motor, and one end of the flexible ventilation component fixed on the secondary spinning motor covers each of the air ducts.

[0010] Preferably, the air duct is a PVC pipe.

[0011] Preferably, the fan includes fan blades and a fan motor for driving the fan blades to rotate, the fan motor being fixedly connected between the fan blades and the air outlet of the fan.

[0012] Preferably, at least one air guide ridge is provided on the side of the fan blade facing the fan motor.

[0013] Preferably, each blade of the fan blade is provided with three air guide ridges.

[0014] Preferably, the flexible ventilation component is a flexible fabric.

[0015] Preferably, the flexible ventilation component is fixed to the fan and the secondary spinning motor by a flexible belt.

[0016] By adopting the aforementioned design scheme, the beneficial effects of this utility model are as follows: This application separates the secondary spinning motor from the fan used for heat dissipation and uses a flexible ventilation component to connect the secondary spinning motor to the air outlet of the fan, which effectively avoids the fan blades of the fan resonating with the secondary spinning motor and damaging the secondary spinning motor. This can effectively improve the service life of the secondary spinning motor, and also avoid motor vibration damaging the fan blades, thereby reducing production costs. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0027] The second traction motor in this embodiment refers to the second traction motor of the spinning equipment. If it is a newly manufactured motor, the fan in the motor can be omitted, and the heat dissipation structure provided in this embodiment can be directly connected to the motor. If it is an old motor that has been modified, the fan in the old motor can be removed and then connected to the heat dissipation structure provided in this embodiment.

[0028] Example 1

[0029] like Figure 1-3 As shown, a heat dissipation structure for a secondary spinning motor includes a fan 20 coaxially arranged with the secondary spinning motor 10. The secondary spinning motor 10 and the fan 20 do not contact each other. A ventilation port is provided on the end of the secondary spinning motor 10 corresponding to the end away from the output shaft of the secondary spinning motor. The ventilation port and the air outlet of the fan are connected by a flexible ventilation component 30. In this embodiment, the fan 20 is placed or fixed on a frame a, so that the fan 20 and the secondary spinning motor 10 are coaxial. The flexible ventilation component 30 is a conventional flexible fabric. The flexible ventilation component 30 is fixed to the fan and the secondary spinning motor by a flexible belt. The flexible belt can be a flexible plastic belt, a flexible rope, etc.

[0030] In this embodiment, the diameter of the air outlet of the fan 20 is greater than or equal to the diameter of the ventilation opening, so that the fan 20 can dissipate heat from the entire secondary spinning motor 10, thereby ensuring the cooling effect of the fan 20 on the secondary spinning motor 10.

[0031] As a preferred embodiment, the outer side of the housing of the secondary spinning motor 10 has a plurality of grooves 11 arranged around the housing. One end of the flexible ventilation component 30 fixed to the secondary spinning motor 10 covers each groove 11, so that the fan 20 can dissipate heat from the housing of the secondary spinning motor 10, thereby further improving the heat dissipation effect.

[0032] In a preferred embodiment, the fan 20 includes a fan blade 21 and a fan motor 22 for driving the fan blade 21 to rotate. The fan motor 22 is fixedly connected between the fan blade 21 and the air outlet of the fan 20 so that the fan 20 can dissipate heat from its own fan motor 22.

[0033] In a preferred embodiment, at least one air guide ridge 23 is provided on the side of the fan blade 21 facing the fan motor 22. In this embodiment, each blade of the fan blade 21 is provided with three air guide ridges 23 to increase the contact area between the fan blade 21 and the air and increase the wind speed.

[0034] Example 2

[0035] like Figure 4-5As shown, the difference between this embodiment and embodiment 1 is that the outer side of the housing of the second spinning traction motor 10 is not provided with a groove 11. Multiple air ducts 12 are fixed to the outer side of the housing of the second spinning traction motor 10 by pasting or locking. One end of the flexible ventilation component 30 fixed to the second spinning traction motor 10 covers each air duct 12. In this embodiment, the air duct 12 is a PVC pipe. By fixing multiple ventilation ducts 12 to the outer side of the housing, a ventilation groove is formed between two adjacent ventilation ducts 12. The ventilation duct 12 itself is also a hollow pipe, which can better cool the housing of the second spinning traction motor 10 and improve the heat dissipation effect.

[0036] In summary, this application effectively avoids the situation where the fan blades 21 of the fan 20 resonate with the second spinning traction motor 10 and the fan 20 used for heat dissipation, and connects the second spinning traction motor 10 and the air outlet of the fan 20 with a flexible ventilation component 30. This effectively prevents the second spinning traction motor 10 from being damaged due to resonance between the fan blades 21 of the fan 20 and the second spinning traction motor 10. It can effectively improve the service life of the second spinning traction motor 10, and at the same time avoid the motor vibration damaging the fan blades 21, thereby reducing production costs.

[0037] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
