Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a fine cotton opening machine. Background Technology

[0002] Currently common cotton opening machines utilize a fan to generate negative pressure, drawing raw cotton into the feeding channel. During movement, a stripping beater and a dust removal knife work together to remove impurities and short fibers, which are then conveyed to the next process by airflow. However, in actual use, the following problems exist: First, during the stripping process, the stripping beater easily rubs the cotton with other components, generating a large amount of lint and reducing cotton quality. Second, because the angle of the dust removal knife relative to the dust cage cannot be adjusted, it is difficult to meet the needs of different raw cotton or processes, easily leading to increased cotton waste and incomplete removal of short fibers, affecting the production quality of subsequent processes. Utility Model Content

[0003] In view of the problems of existing fine cotton opening machines, such as easy rubbing with cotton to produce tufts and the inability to adjust the angle of the dust removal blade relative to the dust cage, this utility model provides a fine cotton opening machine.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A cotton opening machine includes a machine body, a vertical fiber separator, a dust cage, a waste removal component, a cotton feeding component, a dust suction component, and a cotton outlet component.

[0006] Furthermore, the cotton feeding assembly includes a first roller, a second roller, a cylinder, and a cotton feeding roller. The first roller and the second roller are arranged opposite to each other, and the cylinder is arranged opposite to the cotton feeding roller. The diameters of the first roller and the second roller are both larger than the diameters of the cylinder and the cotton feeding roller.

[0007] Furthermore, the dust collection assembly includes a collection hopper and a dust discharge pipe, the collection hopper being located below the dust removal assembly, and the dust discharge pipe being connected to one side of the bottom of the collection hopper.

[0008] Furthermore, the cotton outlet assembly includes a cotton outlet pipe, which is a square-to-round diameter reducing pipe, with the square end of the cotton outlet pipe adjacent to the dust cage, and the upper part of the cotton outlet pipe is bent.

[0009] Furthermore, the support plate is arc-shaped and conforms to the outer contour of the dust cage. Several notches are evenly distributed along the edge of the support plate near the dust cage, forming the first rotation opening. An arc-shaped pressure plate is provided on the support plate, located at the top of the first rotation opening.

[0010] Furthermore, the adjustment plate has several elongated oval second rotating openings, and each of the second rotating openings is arranged in an arc shape that matches the outer contour of the dust cage.

[0024] This utility model discloses a fine cotton opening machine. The following describes one embodiment of this utility model in detail with reference to the accompanying drawings.

[0025] Combination Figure 1 , Figure 2 as well as Figure 3 As shown, a cotton opening machine includes a body 1, a vertical fiber separator 2, a dust cage 7, a dirt removal component, a cotton feeding component, a dust suction component, and a cotton outlet component. The dust cage 7 is installed inside the body 1, and an air duct is formed between the dust cage 7 and the baffle of the body 1. The cotton feeding component is located above the dust cage 7 and includes a first roller 3, a second roller 4, a cylinder 5, and a cotton feeding roller 6. The first roller 3 and the second roller 4 are arranged opposite each other, and the cylinder 5 and the cotton feeding roller 6 are arranged opposite each other. The first roller 3 and the second roller 4 are located above the cylinder 5 and the cotton feeding roller 6, and the diameters of the first roller 3 and the second roller 4 are both larger than the diameters of the cylinder 5 and the cotton feeding roller 6. The dust suction component includes a collection hopper 9, a dust exhaust fan, and a dust exhaust pipe 10. The collection hopper 9 is located below the dust cage 7, and the dust exhaust pipe 10 is connected to one side of the collection hopper 9. Under the action of the dust exhaust fan, negative pressure is generated through the dust exhaust pipe 10 to suck up impurities and short fibers from the material. The cotton outlet assembly includes a cotton outlet pipe 11, which is a square-to-round diameter reducing pipe. The square end of the cotton outlet pipe 11 is adjacent to the dust cage 7 and is connected to the air duct.

[0026] like Figure 4 As shown, the impurity removal components are located between the dust cage 7 and the collection hopper 9. In this embodiment, there are two sets of impurity removal components, each set containing two components. The two components in the same set are arranged symmetrically with respect to the dust cage 7, allowing the user to easily adjust the angle of the dust rod 8 from multiple directions. Both sets of impurity removal components are located below the dust cage 7 and are spaced apart from it. The impurity removal components include a support plate 13, dust rod 8, connecting rod 12, adjusting plate 15, fixing plate 22, and adjusting part. The support plate 13 is arc-shaped and matches the outer contour of the dust cage 7.

[0027] Combination Figure 5 and Figure 6 As shown, the support plate 13 has several notches evenly arranged near the edge of the dust cage 7, forming a first rotation opening. The adjusting plate 15 has several elongated second rotation openings 16, arranged in an arc shape that matches the outer contour of the dust cage 7. The adjusting plate 15 has a connecting hole 18 and two limiting holes 17, both located below the second rotation openings 16, with the connecting hole 18 positioned between the two limiting holes 17. Both the connecting hole 18 and the limiting holes 17 are elongated holes, and each limiting hole 17 is arc-shaped, matching the outer contour of the dust cage 7. The second rotation openings 16 and the connecting hole 18 are arranged vertically, while the two limiting holes 17 are arranged horizontally. A set of limiting bolts is fixedly connected to the machine body 1, each bolt positioned within a limiting hole 17 and movable relative to the limiting hole 17. Each limit bolt is used to ensure that the adjusting plate 15 moves in a preset direction and cooperates with the adjuster to clamp and fix the adjusting plate 15 to prevent the adjusting plate 15 from rotating.

[0028] like Figure 7 As shown, several dust rods 8 are evenly arranged between the support plate 13 and the fixing plate 22. One end of the dust rod 8 is fixedly connected to the connecting rod 12, and the other end is rotatably connected to the fixing plate 22. In this embodiment, the cross-section of the dust rod 8 is triangular. The connecting rod 12 is Z-shaped, with its upper part disposed in the first rotating opening, and an arc-shaped pressure plate 14 is provided at the top of each first rotating opening. The pressure plate 14 is used to prevent the connecting rod 12 from disengaging from the first rotating opening during rotation. The upper end of the connecting rod 12 is fixedly connected to the dust rod 8, and the lower end is disposed in the second rotating opening 16.

[0029] The adjustment unit includes a base 19, a handle, a rotating disk 21, and an eccentric shaft. The rotating disk 21 is disposed within the base 19. The handle is fixedly connected to the center of the rotating disk 21 via a rotating shaft 20 passing through the base 19. The rotating shaft 20 rotates relative to the base 19. The eccentric shaft is eccentric relative to the axis of the rotating disk 21 and is fixedly connected to the bottom of the rotating disk 21. The eccentric shaft is adapted to be inserted into the connecting hole 18.

[0030] In operation, the user feeds cotton or synthetic fibers into the machine body 1 through the vertical fiber separator 2. The cotton is then compressed in the cotton feeding assembly to form lumps. A fan in the machine body 1 rotates, continuously expelling air from the duct and creating negative pressure within the duct, causing the cotton to enter the outlet pipe 11. During rotation, the cotton continuously contacts and collides with the dust rod 8, removing short fibers and dust. The cleaned cotton then enters the outlet pipe 11 and exits the machine body 1. An air inlet is located near the outlet pipe 11, connected to the duct, to provide additional power to propel the cotton along the outlet pipe 11. The dust collection assembly generates negative pressure through a dust collection fan to absorb the removed short fibers and dust, which are then discharged from the machine body 1 through the dust exhaust pipe 10.

[0031] The angle of the dust bar 8 needs to be adjusted according to the type of material to achieve a balance between the cotton loss rate and the impurity removal effect. When adjusting the tilt angle of the dust bar 8, first loosen the limiting bolt, then the user rotates the handle, which in turn drives the eccentric shaft to rotate eccentrically using the rotating disk 21. During this eccentric rotation, the eccentric shaft rotates along the connecting hole 18 and pushes the adjusting plate 15 to move. As the adjusting plate 15 moves, the limiting hole 17 moves relative to the limiting bolt, causing the adjusting plate 15 to move along a preset direction. Simultaneously, during this movement, the adjusting plate 15 drives the connecting rod 12 to rotate through the second rotating port 16. The connecting rod 12 rotates relative to the first rotating port, thereby driving the dust bar 8 to rotate and adjusting the angle of the dust bar 8 relative to the dust cage 7. Finally, tighten the limiting bolt, so that the limiting bolt cooperates with the adjuster fixed to the machine body 1 to clamp and fix the adjusting plate 15, preventing it from moving under gravity.

[0032] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
