Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a heat dissipation fan free of flower accumulation. Background Art

[0002] The spinning frame is the main machine in the spinning process. It is usually driven by a motor and drives the operation of various parts through a gear transmission structure. During the long-term operation of the spinning frame, the heat dissipation of the motor is of top priority.

[0003] Existing cooling fans for motor heat dissipation are usually installed at the tail end of the motor and fixed to the tail end of the main shaft. The cooling fan is driven by the rotation of the main shaft to complete the heat dissipation of the motor. Existing cooling fans, for example, an integrated motor with a forced air cooling structure disclosed in the patent document with application number CN202211295150.0, the cooling fan includes an intermediate shaft and a plurality of fan blades evenly distributed circumferentially on the outer ring of the intermediate shaft. The fan blades are driven to rotate by the intermediate shaft to complete the heat dissipation of the motor. However, when such fans are applied to spinning machine motors, due to the large number of limit stops in the spinning environment, flower accumulation is easily generated at the connection position between the cooling fan and the motor, affecting the heat dissipation effect of the cooling fan. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a heat dissipation fan without flower accumulation.

[0005] The technical solution of this utility model is as follows:

[0006] A heat dissipation fan without flower accumulation comprises a connecting mechanism which can be coaxially connected to the rear end of a motor drive shaft, a heat dissipation mechanism is arranged on the front side of the connecting mechanism, and the connecting mechanism can be driven to rotate by the rotation of the motor drive shaft, and finally the heat dissipation work of the motor is completed through the heat dissipation mechanism.

[0007] As the core technical concept of the present utility model, the heat dissipation fan also includes a protective mechanism arranged on the outer ring of the heat dissipation mechanism. Specifically, the connecting mechanism includes an annular protective plate, whose inner ring is provided with a connecting piece that can be coaxially connected to the tail end of the transmission shaft; the heat dissipation mechanism includes a plurality of fan blades circumferentially arranged on the front plate surface of the protective plate (the plate surface away from the motor side in the use state), and the protective plate is driven to rotate by the transmission shaft, thereby driving the fan blades to rotate to complete the heat dissipation work of the motor; the protective mechanism includes a ring plate connected to the front side of the plurality of fan blades and coaxially arranged with the protective plate, and the rear outer ring of the ring plate is coaxially provided with a protective tube, and the connecting mechanism and the heat dissipation mechanism are both located inside the protective tube. On the basis of this structure, the rear end of the protective tube can be contracted and sheathed on the rear end outer ring of the motor, and a heat dissipation channel separated by a plurality of fan blades is formed between the protective tube and the outer ring of the protective plate, and between the ring plate and the protective plate, thereby preventing the accumulation of fibers entering the interior of the heat dissipation fan during the rotation of the heat dissipation fan, thereby ensuring the heat dissipation effect of the heat dissipation fan.

[0008] As described above, a flower accumulation-free cooling fan is, as a preferred embodiment, the distance between the plane where the rear end of the protective tube is located and the rear plate surface of the protective plate is not less than 5 cm, so as to ensure the depth of the motor tail end extending into the protective tube, prevent fibers from entering the cooling fan from between the protective tube and the motor, and ensure the flower accumulation-free protective effect of the protective tube.

[0009] As a further preference, the inner diameter of the ring plate is smaller than the outer diameter of the protective plate, so as to prevent fibers from entering the interior of the cooling fan along the cooling channel from the front side of the cooling fan, further ensuring the anti-flowering effect of the cooling fan.

[0010] In order to further improve the fiber protection effect achieved by the cooperation between the protection plate and the ring plate, the difference between the outer diameter of the protection plate and the inner diameter of the ring plate is set to be no less than 1.5 cm.

[0011] As described above, a heat dissipation fan without flower accumulation, specifically speaking, includes a connecting tube, and the protective plate is coaxially arranged on the outer ring of the rear end of the connecting tube; a connecting plate is coaxially arranged in the middle part of the connecting tube, and a plurality of connecting holes that can be coaxially connected to the rear end of the transmission shaft are opened circumferentially on the connecting plate.

[0012] As a preferred embodiment, in order to ensure the structural strength of the connecting plate and the connection strength between the connecting plate and the connecting tube, reinforcing ribs are further connected between the connecting plate and the inner ring of the connecting tube.

[0013] In order to ensure the connection strength between the fan blades and the protective mechanism, a connection rib connected to the inner ring of the casing is further provided on the outer side of the fan blade (the side away from the axis of the protective plate) for the heat dissipation fan without flower accumulation as described above.

[0014] In order to further improve the fiber protection effect achieved by the cooperation of the protective plate and the ring plate and prevent the fibers from passing through the protective plate and the ring plate and entering the interior of the cooling fan, the distance between the front plate surface of the protective plate and the rear plate surface of the ring plate is 2-7 cm.

[0015] As a preferred implementation, the distance between the front surface of the protective plate and the rear surface of the ring plate is 3 cm.

[0016] For the above-mentioned flower-free heat dissipation fan, in order to ensure the overall structural strength of the heat dissipation fan, the connection mechanism, the heat dissipation mechanism and the protection mechanism are integrally processed and formed, for example, they can be 3D printed.

[0017] The beneficial effect of the utility model is that the utility model is a heat dissipation fan free of flower accumulation, the rear end of the protective tube can be covered on the rear end outer ring of the motor in a covering shape, and a heat dissipation channel separated by a plurality of fan blades is formed between the protective tube and the outer ring of the protective guard plate, and between the ring plate and the protective plate, thereby preventing the flower accumulation caused by fibers entering the heat dissipation fan during the rotation of the heat dissipation fan, thereby ensuring the heat dissipation effect of the heat dissipation fan.

A heat dissipation mechanism 2 is provided on the front side of the connecting mechanism 1. The rotation of the motor drive shaft can drive the connecting mechanism 1 to rotate, and finally the heat dissipation work of the motor is completed through the heat dissipation mechanism 2. The structure of the heat dissipation fan is described in detail below.

[0032] In this embodiment, the structure of the connecting mechanism 1 includes an annular protective plate 15 , and the inner ring of the protective plate 15 is provided with a connecting piece that can be coaxially connected to the rear end of the transmission shaft.

[0034] As a preferred embodiment, in order to ensure the structural strength of the connecting plate 12 and the connection strength between the connecting plate 12 and the connecting tube 11 , a reinforcing rib 14 is further connected between the connecting plate 12 and the inner circle of the connecting tube 11 .

[0035] In this embodiment, the heat dissipation mechanism 2 includes a plurality of fan blades 21 circumferentially arranged on the front surface of the protective plate 15 (the surface away from the motor side in the use state). The fan blades 21 are plate-like structures, one side of which is connected to the protective plate 15 and the plate surface is perpendicular to the protective plate 15. The protective plate 15 is driven to rotate by the transmission shaft, and then the fan blades 21 are driven to rotate, thereby completing the heat dissipation work of the motor.

[0037] Specifically speaking, the structure of the protection mechanism 3 includes an annular plate 31 connected to the front side of a plurality of blades 21 and coaxially arranged with the protection plate 15, the plate surface of the annular plate 31 is parallel to the plate surface of the protection plate 15, and a protective tube 32 is coaxially arranged on the outer ring of the rear side thereof, and the connecting mechanism 1 and the heat dissipation mechanism 2 are both located inside the protective tube 32.

[0039] As a further preference, the inner diameter of the ring plate 31 is smaller than the outer diameter of the protective plate 15, so as to prevent fibers from entering the interior of the cooling fan along the cooling channel from the front side of the cooling fan, further ensuring the anti-flowering effect of the cooling fan.

[0040] In order to further improve the fiber protection effect achieved by the cooperation between the protection plate 15 and the ring plate 31, the difference between the outer diameter of the protection plate 15 and the inner diameter of the ring plate 31 is set to be no less than 1.5 cm.
