Description

Technical Field

[0001] This utility model belongs to the field of spinning machine technology, specifically relating to a heat dissipation device for the front bearing of the main motor of a spinning machine. Background Technology

[0002] With the continuous development of the spinning industry, ring spinning machines are constantly evolving towards ultra-long spindles and ultra-high speeds, which improves both output and quality. This, in turn, requires a continuous increase in the power of the main motor of the ring spinning machine, often requiring 90KW, 110KW, or even larger main motors. However, a larger main motor often means a larger size. As the main motor increases in size, the space inside the transmission housing of the ring spinning machine becomes insufficient, making the problem of poor heat dissipation of the main motor increasingly prominent.

[0003] The main motor used in a spinning machine usually has a built-in cooling fan at its tail end, which can effectively dissipate heat from the tail end and sides of the main motor. However, the cooling effect at the front of the main motor, especially at the output end, is poor, and the temperature often becomes too high. At this time, the grease in the bearing at the output end dries up, which seriously affects the service life of the main motor. Utility Model Content

[0004] In view of this, the present invention provides a front bearing heat dissipation device for the main motor of a spinning frame, which aims to partially intercept the air originally discharged from the air box exhaust port of the spinning frame air box and guide the intercepted air to the front bearing of the main motor, thereby achieving heat dissipation of the front bearing of the main motor.

[0005] A cooling device for the front bearing of the main motor of a spinning frame is installed on the frame of the spinning frame for cooling the main motor. The main motor is located on the bottom plate of the spinning frame, and the cooling device for the front bearing is located above the main motor. The output end of the main motor is provided with a front bearing.

[0006] The front bearing heat dissipation device includes:

[0007] The bellows is mounted on the frame and is located above the main motor. A bellows exhaust port is provided on one side of the bottom of the bellows. The bellows exhaust port passes through the frame and connects to the area on the bottom plate where the main motor is placed. The bellows exhausts air through the bellows exhaust port.

[0008] The air duct includes an air inlet and an air outlet. The air inlet is positioned opposite to the air box exhaust port and partially blocks the air box exhaust port, introducing part of the air output from the air box exhaust port into the air duct. The air outlet is located directly above the front bearing, blowing the air in the air duct toward the front bearing.

[0009] Preferably, the horizontal width of the air duct does not exceed the horizontal width of the frame, and the length of the air duct is the horizontal distance from the air box exhaust port to the front bearing.

[0010] Furthermore, the area of ​​the air inlet is one-third of the area of ​​the air box exhaust outlet.

[0011] Preferably, the air duct is detachably mounted on the lower surface of the frame.

[0012] Furthermore, the air duct is detachably mounted on the lower surface of the frame via clamps.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention, based on the original spinning frame, partially intercepts the air originally discharged from the air box exhaust port and guides the intercepted air to the front bearing position using an air guide pipe. This allows the front bearing heat dissipation device to complete the heat dissipation of the front bearing by relying on the configuration of the spinning frame body. This not only prevents the front bearing grease from solidifying, but also reduces the cost of building an additional heat dissipation device, which helps to extend the service life of the main motor and improve the stability of the spinning frame operation.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model; the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In addition, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0021] This technical solution provides a front bearing heat dissipation device for the main motor of a spinning frame, which is mounted on the frame 1 of the spinning frame and used to dissipate heat from the main motor 2. The main motor 2 is located on the base plate 3 of the spinning frame, and the front bearing heat dissipation device is located above the main motor 2. A front bearing 201 is provided at the output end of the main motor 2. Figure 1 As shown, the front bearing heat dissipation device includes: a fan box 4 and a duct 5.

[0022] Among them, such as Figure 1 As shown, the air box 4 is mounted on the frame 1 and is located above the main motor 2. An air box exhaust port 401 is provided on the bottom side of the air box 4. The air box exhaust port 401 passes through the frame 1 and connects with the area on the base plate 3 where the main motor 2 is placed.

[0023] It should be noted that the bellows 4 is a necessary device for all existing spinning machines, providing negative pressure for cotton suction during the spinning process. Therefore, the bellows 4 needs to exhaust air. As a result, there will always be air inside the bellows 4 during normal operation of the spinning machine, and the air will be discharged through the bellows exhaust port 401. This utility model intercepts and utilizes part of the air inside the bellows 4 bellows exhaust port 401, achieving the heat dissipation effect for the front bearing 201, while also reducing the cost of building an additional heat dissipation device.

[0024] The following section will explain how to partially intercept and guide the airflow from the bellows exhaust port 401.

[0025] like Figure 1-3As shown, the air duct 5 includes an air inlet 501 and an air outlet 502. The air inlet 501 is positioned opposite to the air box exhaust port 401 and partially blocks the air box exhaust port 401, introducing part of the air output from the air box exhaust port 401 into the air duct 5. The air outlet 502 is located directly above the front bearing 201, blowing the air in the air duct 5 towards the front bearing 201.

[0026] Specifically, the horizontal width of the air duct 5 does not exceed the horizontal width of the frame 1, the length of the air duct 5 is the horizontal distance from the air box exhaust port 401 to the front bearing 201, and the direction of the arrow in the figure is the direction of air flow.

[0027] Based on this, such as Figure 1 As shown, the air inlet 501 intercepts part of the air at the air box exhaust port 401. Therefore, the area of ​​the air inlet 501 is smaller than the area of ​​the air box exhaust port 401. In this embodiment, the area of ​​the air inlet 501 is one-third of the area of ​​the air box exhaust port 401. That is, the air duct 5 intercepts one-third of the air at the air box exhaust port 401 and guides it to dissipate heat from the front bearing 201. The remaining two-thirds of the air blows directly onto the main motor 2 for heat dissipation.

[0028] In addition, the air duct 5 is detachably mounted on the lower surface of the frame. In this embodiment, taking the clamp 6 as an example, the air duct 5 is detachably mounted on the lower surface of the frame 1 through the clamp 6, which enhances the stability of the air duct 5 during long-term use and provides a long-term heat dissipation function for the front bearing 201.

[0029] In general, this utility model, based on the original spinning machine, partially intercepts the air originally discharged from the air box 4 through the air box exhaust port 401, and uses the air guide pipe 5 to guide the intercepted air to the front bearing 201. This allows the front bearing heat dissipation device to complete the heat dissipation of the front bearing 201 by relying on the configuration of the spinning machine body. This not only prevents the grease in the front bearing 201 from solidifying, but also reduces the cost of building an additional heat dissipation device, which helps to extend the service life of the main motor 2 and improve the stability of the spinning machine operation.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
