DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0038] In an embodiment: refer to Figures 1-8 , the air suction device relates to the technical field of textile machinery, and mainly comprises a gantry 1, a U-shaped moving frame 4, a blowing structure, an air suction structure and a reciprocating structure.

[0039] refer to Figure 1 and Figure 2, the gantry 1 is provided with a groove 2 at the top, and a lead screw 3 is rotatably connected in the groove 2. A U-shaped moving frame 4 is slidably connected at the top of the gantry 1, and a nut block is fixed in the U-shaped moving frame 4 and threadedly connected with the lead screw 3. When the lead screw 3 rotates, the U-shaped moving frame 4 can move linearly at the top of the gantry 1. In actual application, the rotation of the lead screw 3 can be driven by a motor, and the motor is connected with one end of the lead screw 3 through a coupling. The forward and reverse rotation of the motor can realize the reciprocating movement of the U-shaped moving frame 4 at the top of the gantry 1. For example, when the motor rotates forward, the lead screw 3 drives the U-shaped moving frame 4 to move in one direction; when the motor reverses, the lead screw 3 drives the U-shaped moving frame 4 to move in the opposite direction. This moving mode enables the U-shaped moving frame 4 to cover most of the area of the spinning machine, providing a moving basis for subsequent cleaning work.

[0040] With reference to Figure 1 and Figure 2 , two wave plates 44 are fixed on the two sides of the gantry 1. The wave plate 44 is in a wave shape, and cooperates with the related parts on the U-shaped moving frame 4 during the movement of the U-shaped moving frame 4 to realize a specific motion effect, which will be described in detail later.

[0041] With reference to Figure 3 and Figure 4 , the blowing structure is arranged in the U-shaped moving frame 4 and is mainly used for blowing the lint attached to the spinning machine. The blowing structure includes a base 5 fixed to the inner wall of the top of the U-shaped moving frame 4, and a plurality of first rotating cylinders 6 are rotatably connected in the base 5 and arranged in an up-down manner. An L-shaped plate 12 is slidably connected to the inner wall of one side of the U-shaped moving frame 4 and can slide up and down in the vertical direction. A plurality of first connecting rods 13 are rotatably connected to one side of the L-shaped plate 12, and one end of each of the first connecting rods 13 is rotatably connected with one end of an adjacent first rotating cylinder 6. When the L-shaped plate 12 moves up and down, the first rotating cylinders 6 can be driven to swing up and down through the transmission of the first connecting rods 13. This swinging mode enables the airflow discharged from the first rotating cylinders 6 to blow towards the spinning machine at different angles, thereby fully cleaning the gaps of the spinning machine and improving the cleaning effect.

[0042] With reference to Figure 2 and Figure 4The moving rod 15 is slidably arranged in the base 5, one end of the moving rod 15 is rotatably connected with a guide wheel 16, and the guide wheel 16 cooperates with the wave plate 44. When the U-shaped moving frame 4 moves, the guide wheel 16 rolls along the wave surface of the wave plate 44, and due to the ups and downs of the wave surface, the guide wheel 16 drives the moving rod 15 to move linearly back and forth. The top of the L-shaped plate 12 is rotatably connected with a second connecting rod 14, and the top end of the second connecting rod 14 is rotatably connected with the moving rod 15. When the moving rod 15 moves back and forth, through the transmission of the second connecting rod 14, the L-shaped plate 12 can be driven to move up and down back and forth. For example, when the moving rod 15 moves outward, the L-shaped plate 12 is driven upward by the second connecting rod 14; when the moving rod 15 moves in the opposite direction, the L-shaped plate 12 is driven downward.

[0043] With reference to Figure 4 The uppermost first rotating cylinder 6 is fixedly connected with the air injection hose 11, and the other end of the air injection hose 11 is connected with an external air blower. The external air blower injects air into the uppermost first rotating cylinder 6 through the air injection hose 11, and the air is sequentially transmitted to the lower first rotating cylinders 6 through the connecting hose 10. One end of each first rotating cylinder 6 is fixedly connected with an air outlet pipe 7, and the air is discharged through the air outlet pipe 7 to blow the lint attached to the spinning machine, which is convenient for the later adsorption and removal of the lint.

[0044] With reference to Figure 5 The air outlet pipe 7 is slidably connected in the first rotating cylinder 6, and a plurality of spiral guide vanes 8 are fixedly arranged on the inner wall of the air outlet pipe 7 close to one end. When the air is discharged from the air outlet pipe 7 to the outside, the spiral guide vanes 8 force the airflow to flow along a spiral path, forming a rotating jet vortex. This flow mode can reduce the frictional resistance of the airflow to the pipe wall, avoid the boundary layer separation phenomenon commonly seen in traditional straight blowing airflow, thereby reducing energy loss, improving outlet air speed, and improving the blowing effect of the lint. In addition, since the air outlet pipe 7 is located at different distances from the position where the lint accumulates on the spinning machine, in order to fully blow the lint, the length of the air outlet pipe 7 can be controlled by pulling out the air outlet pipe 7, so that the air outlet pipe 7 is close to the position to be cleaned. One end of the first rotating cylinder 6 is fixedly connected with a rubber ring 9, and the rubber ring 9 is arranged on the outer wall of the air outlet pipe 7. The friction between the rubber ring 9 and the air outlet pipe 7 can ensure the stability of the position of the air outlet pipe 7, so that the air outlet pipe 7 remains stable after being extended to a specified length. For example, when it is necessary to clean the lint accumulation position far away, the air outlet pipe 7 can be pulled outwards so that the air outlet pipe 7 is close to the position, and then the friction between the rubber ring 9 and the air outlet pipe 7 can prevent the air outlet pipe 7 from moving randomly, thereby ensuring the blowing effect.

[0045] With reference to Figure 2 , Figure 3 andFigure 7 The suction structure is arranged on both sides of the U-shaped moving frame 4, mainly used for adsorbing and cleaning the lint blown up. The suction structure comprises a plurality of suction pipes 18 fixedly penetrating the U-shaped moving frame 4 and a filter box 20 fixed on one side of the U-shaped moving frame 4. The bottom of the filter box 20 is fixed with a communication pipe 19, and one end of each of the plurality of suction pipes 18 is fixedly communicated with the communication pipe 19. A filter plate 22 is fixed in the filter box 20, and the filter plate 22 is used to filter the lint in the air entering the filter box 20. A suction hose 21 located above the filter plate 22 is fixed on one side of the filter box 20, and the suction hose 21 is communicated with an external suction pump. After the lint on the spinning frame is blown up by the air outlet pipe 7, the external suction pump can suck the lint floating in the air into the filter box 20 through the cooperation of the suction hose 21, the communication pipe 19 and the suction pipe 18, and the filter plate 22 filters the lint, so that the lint is left below the filter plate 22, and the clean air is discharged above the filter plate 22.

[0046] With reference to Figure 7 Both sides of the filter box 20 are fixed with a collection box 26, and both sides of the filter box 20 are provided with a discharge port 27 communicated with the collection box 26. The inner wall of the bottom of each of the two discharge ports 27 is fixed with a guide plate 28, which is used to guide the lint to the collection box 26 for collection when the lint is scraped off by the scraper 25.

[0047] With reference to Figure 4 , Figure 6 , Figure 7 and Figure 8 The reciprocating structure is mainly used for cleaning and collecting the lint adsorbed and filtered in the filter box 20. The reciprocating structure comprises a threaded rod 23 rotating in the filter box 20, and the threaded rod 23 is located above the filter plate 22. A wind shield 24 located at the top of the filter plate 22 is slidingly connected in the filter box 20, and a nut block is fixed in the wind shield 24, and the wind shield 24 is threadedly connected with the threaded rod 23 through the nut block. When the threaded rod 23 rotates, the wind shield 24 can move linearly in the filter box 20. A scraper 25 located at the bottom of the filter plate 22 is slidingly connected in the filter box 20, and a plurality of magnets are embedded in the top of the scraper 25 and the bottom of the wind shield 24, and magnetic attraction is generated between the upper and lower adjacent magnets. When the wind shield 24 moves, the scraper 25 can be moved by the magnetic force between the magnets to scrape off the lint adsorbed at the bottom of the filter plate 22. The wind shield 24 is located directly above the scraper 25, and the width of the wind shield 24 is greater than the width of the scraper 25. This design can reduce the force of the lint adsorbed on the filter plate 22 above the scraper 25 when the scraper 25 scrapes off the lint, facilitating the cleaning of the lint by the scraper 25.

[0048] With reference to Figure 7The side of the filter box 20 is fixed with a gearbox 29 through the frame, and the output shaft of the gearbox 29 is fixedly connected with one end of the threaded rod 23. The input shaft of the gearbox 29 is fixed with a spur gear 30, and the top of the moving rod 15 is fixed with a rack 17 engaged with the spur gear 30. When the moving rod 15 reciprocates, the input shaft of the gearbox 29 can be driven to rotate through the cooperation of the spur gear 30 and the rack 17. The gearbox 29 drives the threaded rod 23 to rotate after adjusting the rotating speed, and the threaded rod 23 drives the wind shield 24 to reciprocate. For example, when the moving rod 15 moves in one direction, the rack 17 drives the spur gear 30 to rotate, the spur gear 30 drives the threaded rod 23 to rotate through the gearbox 29, and the threaded rod 23 drives the wind shield 24 to move in one direction; when the moving rod 15 moves in the opposite direction, the wind shield 24 moves in the opposite direction. The scraper 25 is driven to move by the magnetic force between the corresponding two magnets, and the lint attached to the bottom of the filter plate 22 can be scraped off, and then discharged into the collection box 26 through the guide plate 28, which not only facilitates unified treatment later, but also avoids clogging of the filter plate 22.

[0049] Referring to Figure 7 The two sides of the scraper 25 are provided with downwardly bent bending parts, and when the scraper 25 scrapes the lint, the lint will move to above the discharge port 27 along the bending parts, so that the lint can be collected into the collection box 26.

[0050] Referring to Figure 2 The two sides of the U-shaped moving frame 4 are fixed with shielding plates 43, which are used to avoid the lint floating to a higher position when the first rotating cylinder 6 blows the lint, so as to facilitate the lint being adsorbed by the air suction pipe 18 later.

[0051] In another embodiment, referring to Figure 9 and Figure 10 Based on the embodiment 1, the bottom two ends of the U-shaped moving frame 4 are rotatably connected with second rotating cylinders 31, the outer wall of the second rotating cylinder 31 is fixedly provided with a closed plate 36, and the bottom of the closed plate 36 is slidably connected with an air suction box 37. The top of the air suction box 37 is provided with a rectangular accommodation groove 38, the bottom end of the second rotating cylinder 31 extends into the rectangular accommodation groove 38, the rectangular accommodation groove 38 is used to accommodate the movement of the second rotating cylinder 31, and the closed plate 36 is used to close the rectangular accommodation groove 38. The bottom of the air suction box 37 is fixedly provided with a plurality of air suction nozzles 41, which are used to adsorb the lint on the ground.

[0052] The top of the second rotating cylinder 31 is rotationally connected with a connecting pipe 32, and the top end of the connecting pipe 32 is fixedly communicated with the bottom end of the communicating pipe 19. The outer wall of the second rotating cylinder 31 is fixedly sleeved with a bevel gear ring 33, and the U-shaped moving frame 4 is fixedly provided with a driving motor 34, and the output shaft of the driving motor 34 is fixedly provided with a bevel gear 35 engaged with the bevel gear ring 33. When the driving motor 34 works, the second rotating cylinder 31 can be driven to rotate through the cooperation of the bevel gear 35 and the bevel gear ring 33.

[0053] The inner wall of the top of the air suction box 37 is slidably connected with two guide rods 39, and the ends of the two guide rods 39 close to each other are fixedly connected with the two sides of the second rotating cylinder 31, respectively. The outer walls of the two guide rods 39 are both sleeved with springs 40, and the parameter ranges of the springs 40 are as follows: the wire diameter of the spring 40 is between 0.5-2mm, the outer diameter is between 5-20mm, the free length is between 20-100mm, and the spring stiffness is between 1-10N / mm. The ends of the two springs 40 close to each other are both fixedly connected with the second rotating cylinder 31 through spring seats, and the ends of the springs 40 away from the second rotating cylinder 31 are fixedly connected with the air suction box 37 through spring seats. The spring 40 is used to reset the air suction box 37 after displacement between the air suction box 37 and the second rotating cylinder 31.

[0054] The two sides of the air suction box 37 are both fixedly provided with arc-shaped plates 42, which are used to move and give way when the air suction box 37 encounters obstacles during rotation. When the driving motor 34 works, the second rotating cylinder 31 is driven to rotate through the cooperation of the bevel gear 35 and the bevel gear ring 33, the air suction box 37 is driven to rotate by the guide rod 39, and then the lint on the ground is adsorbed. When the air suction box 37 encounters obstacles during rotation, the arc-shaped plate 42 can drive the air suction box 37 to move to one side under the action of the obstacle, the second rotating cylinder 31 moves in the rectangular giving way slot 38, and the closing plate 36 always closes the rectangular giving way slot 38, so that the self-adaptive effect can be achieved when encountering obstacles, and the air suction box 37 can smoothly adsorb lint. After passing through the obstacle, the air suction box 37 is reset under the action of the spring 40, so that the second rotating cylinder 31 is located at the center position of the air suction box 37, and the adsorption of lint continues.
