Figure 4 As shown, the air duct 200 is connected with the air outlet of the centrifugal fan 100, so that the air blown by the centrifugal fan 100 passes through the air duct 200 and is blown out from the air outlet of the air duct 200, the outlet of the air duct 200 is located in the lint collecting drum, and the air blown by the centrifugal fan 100 blows up the primary felt on the lint collecting drum after passing through the air duct 200, and the primary felt blown up by the air is driven by the lint collecting drum to deviate from the air outlet of the air duct 200 by a certain distance and then falls to the subsequent conveying mechanism (not shown in the figure) under the action of gravity.

[0028] In the lint collecting machine, the air volume blown by the air duct is mostly adjusted by adjusting the power of the centrifugal fan, and in the present application, please refer to Figure 2 and Figure 3 As shown, the air duct 200 is connected with the air outlet of the centrifugal fan 100, so that the air blown by the centrifugal fan 100 passes through the air duct 200 and is blown out from the air outlet of the air duct 200, the outlet of the air duct 200 is located in the lint collecting drum, and the air blown by the centrifugal fan 100 blows up the primary felt on the lint collecting drum after passing through the air duct 200, and the primary felt blown up by the air is driven by the lint collecting drum to deviate from the air outlet of the air duct 200 by a certain distance and then falls to the subsequent conveying mechanism (not shown in the figure) under the action of gravity. Figure 5 As shown, the air duct 200 is connected with the air outlet of the centrifugal fan 100, so that the air blown by the centrifugal fan 100 passes through the air duct 200 and is blown out from the air outlet of the air duct 200, the outlet of the air duct 200 is located in the lint collecting drum, and the air blown by the centrifugal fan 100 blows up the primary felt on the lint collecting drum after passing through the air duct 200, and the primary felt blown up by the air is driven by the lint collecting drum to deviate from the air outlet of the air duct 200 by a certain distance and then falls to the subsequent conveying mechanism (not shown in the figure) under the action of gravity.

[0029] Please refer to Figure 3 and Figure 5As shown, the outer air flow port 301 is in the shape of a quadrilateral, the width of the outer air flow port 301 increases along its length, the width of the end of the outer air flow port 301 adjacent to the circular ring set 300 is greater than the width of the other end, the inner air flow port 201 is in the shape of a square, the length of the inner air flow port 201 is equal to the span of the bottom end surface of the outer air flow port 301, and the width of the inner air flow port 201 is equal to the height of the outer air flow port 301. When the centrifugal fan 100 is not working, there is no gas flowing in the air duct 200, the inner air flow port 201 and the outer air flow port 301 are staggered (there is no area where the inner air flow port 201 and the outer air flow port 301 are connected), and the inner wall of the circular ring set 300 blocks the inner air flow port 201, so that gas is only blown out of the sleeve 401. When the centrifugal fan 100 is working, the wind blown out of the centrifugal fan 100 enters the air duct 200, part of the wind is blown out of the sleeve 401, and the other part of the wind exerts pressure on the inner wall of the air duct 200 where the sleeve 401 is installed. The pressure direction of the air duct 200 is consistent with the flow direction of the wind, so that the air duct 200 moves along the flow direction of the wind, the opening of the air flow passage 302 composed of the outer air flow port 301 and the inner air flow port 201 becomes larger, and the part of the wind blown out of the centrifugal fan 100 is facilitated to flow out of the air flow passage 302, achieving the purpose that the size of the air flow passage 302 corresponds to the flow speed of the wind blown out of the centrifugal fan 100 (the faster the flow speed of the wind, the larger the size of the air flow passage 302), thereby avoiding that the wind volume is concentrated to be directly blown to the lint drum from the sleeve 401, and causing the felt to be broken in one time.

[0030] Please refer to Figure 3 As shown, the air duct 200 and the circular ring set 300 are provided with a restoring part 400, the restoring part 400 is located in the circumferential direction of the sleeve 401, the restoring part 400 is used to return the air duct 200 to the original position, the restoring part 400 is in the shape of a spiral copper wire, the air duct 200 is subjected to the wind force of the wind blown out of the centrifugal fan 100, the restoring part 400 is subjected to force contraction and serves as a restoring force, when the wind volume becomes small, the air duct 200 is returned to the original position by the restoring force of the restoring part 400, so that the position of the air duct 200 changes with the change of the wind volume (when the wind volume becomes small or the air duct 200 is not working, the air duct 200 can return to the original position).

[0031] Please refer to Figure 6 As shown, the circular ring set 300 is provided with a track 303, and the air duct 200 is provided with a protrusion 202 in sliding connection with the track 303, the direction in which the protrusion 202 moves on the track 303 is parallel to the axis of the circular ring set 300, and the air duct 200 can move relative to the circular ring set 300 through the cooperation of the protrusion 202 and the track 303. Further, please refer to Figure 4 As shown, one end of the sleeve 401 is flush with the circular ring set 300, and the other end extends into the air duct 200, which is used to compensate for the movement distance of the air duct 200 relative to the circular ring set 300.

[0032] Please refer toFigure 4 and Figure 5 As shown in FIG. 6, due to the sliding fit of the circular ring assembly 300 and the air duct 200, there is a gap between the two, the connecting hose 500 is installed between the outer air flow port 301 and the inner air flow port 201, so as to avoid the wind entering the air duct 200 from flowing into the gap between the circular ring assembly 300 and the air duct 200 through the inner air flow port 201, resulting in the loss of wind flow, and only the wind flowing out of the air flow channel 302 can enter the gap between the circular ring assembly 300 and the air duct 200 through the outer air flow port 301. Figure 5 The position of the connecting hose 500 is drawn in FIG. 6, and the position of the connecting hose 500 is not drawn in the other figures. The connecting hose 500 is made of rubber material.

[0033] Further, the connecting hose 500 is installed with a buffer plate 501 at one end, the buffer plate 501 is adjacent to the air duct 200 at one end, the buffer plate 501 is located in the outer air flow port 301, the included angle between the buffer plate 501 and the connecting hose 500 is greater than 90°, the included angle between the buffer plate 501 and the length direction of the inner air flow port 201 is less than 90°, and further, the buffer plate 501 is located in the intersection area of the outer air flow port 301 and the air flow channel 302. When the centrifugal fan 100 is not working, the connecting hose 500 is in a compressed state, the end of the buffer plate 501 not connected with the connecting hose 500 is subjected to the pulling force of the connecting hose 500, resulting in that the distance between the end of the buffer plate 501 not connected with the connecting hose 500 and the air duct 200 becomes larger. When the wind blown by the centrifugal fan 100 enters the air duct 200, the air duct 200 moves together with the moving direction of the wind, the buffer plate 501 is subjected to the partial pulling force of the connecting hose 500 and the wind force, resulting in that the pulling force of the buffer plate 501 is reduced, the distance between the end of the buffer plate 501 not connected with the connecting hose 500 and the air duct 200 becomes smaller. At this time, the wind discharged from the air flow channel 302 blows to the buffer plate 501, changes the flow direction of part of the wind discharged from the air flow channel 302, and the wind changing the flow direction plays a role of buffering the wind discharged from the air flow channel 302. When the wind amount is large, the change of the flow direction of the wind blowing to the buffer plate 501 is large, the wind amount entering the air duct 200 is effectively controlled, and it is not necessary to control the power of the centrifugal fan 100.

[0034] The specific work of the present application: the wind of centrifugal fan 100 into the wind pipe 200, the closed end of the wind pipe 200 is subjected to the wind of centrifugal fan 100, the convex 202 moves along the track 303, the moving direction of the convex 202 is same with the wind direction, the size of the airflow passage 302 composed of the outer airflow port 301 and the inner airflow port 201 becomes larger, the amount of wind discharged from the airflow passage 302 is larger in the same time, the movement of the wind pipe 200 makes the distance between the one end of the buffer plate 501 not contacted with the connecting hose 500 and the wind pipe 200 smaller, the wind direction of the part of wind discharged from the airflow passage 302 is changed through the buffer plate 501, the shunting of the amount of wind inside the wind pipe 200 is realized through the airflow passage 302, so as to achieve the control of the amount of wind acting on the primary felt, when the centrifugal fan 100 does not work, the size of the airflow passage 302 becomes smaller through the restoring part 400 between the closed end of the wind pipe 200 and the closed end of the circular ring set 300, according to the different amount of wind blown by the centrifugal fan 100, the size of the airflow passage 302 can be automatically changed, further controlling the amount of wind acting on the primary felt.

[0035] The above only describes the preferred embodiments of the present application and is not used to limit the present application, although the present application is described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement for part of the technical features.
