Technical Field

[0001] This utility model relates to the technical field of cotton cleaning machines, specifically a multi-stage airflow cotton cleaning machine. Background Technology

[0002] Lint is cotton fiber obtained directly from cotton plants after being harvested and processed through a ginning process, separating it from cotton seeds. This fiber is unprocessed and retains its original form, making it a commonly used natural cotton raw material in the textile industry. Lint often needs to be cleaned before processing to remove impurities such as dust, dead fibers, and leaf debris that may be present on the lint, in order to ensure the normal progress of subsequent processing.

[0003] However, existing methods for removing impurities from cotton lint have the following problems: because some impurities are located inside the cotton lint, existing cleaning machines have difficulty effectively cleaning impurities inside the cotton lint, affecting the cleaning effect. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content

[0020] 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.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a multi-stage airflow cotton cleaning machine, including a machine body 1, a conveyor 2, a sawtooth turning assembly, a swing-type airflow dispersing mechanism, and a negative pressure suction assembly. The machine body 1 has air inlets 3 on both its left and right sides and two sets of discharge outlets 4 at its bottom. A feed inlet 5 is located below the right-side air inlet 3. The conveyor 2 is horizontally installed at the feed inlet 5. The sawtooth turning assembly is located on one side of the feed inlet 5 and installed inside the machine body 1. The sawtooth turning assembly includes a motor 6. A rotating roller 7 is installed at the power output end of motor 6. Several sets of toothed blades 8 are installed on the surface of the rotating roller 7. A separator 9 is also installed on the lower left side of the sawtooth turning assembly. A discharge chamber 10 is opened on the left side of the separator 9. The discharge chamber 10 is connected to one of the discharge ports 4. A horizontal plate 11 is installed at the air inlet 3 on the right side. The swing-type airflow dispersing mechanism and the negative pressure suction assembly are both installed at the bottom of the horizontal plate 11. The swing-type airflow dispersing mechanism includes a bracket 12, a support plate 13, and an air guide plate. 14. A swing plate 15, a driver 16, and a return spring 17 are provided. Two sets of brackets 12 are symmetrically mounted on the horizontal plate 11. A support plate 13 is mounted at the bottom of the two sets of brackets 12 and has a ventilation channel 18 in the middle. A guide plate 14 covers the support plate 13 and is connected to the horizontal plate 11 via a pipe. A blower 19 is mounted on the right end of the horizontal plate 11. The swing plate 15 is movably mounted at the bottom of the support plate 13. The driver 16 is mounted at one end of the support plate 13. The return spring 17 is located on the support plate 11. At the other end of the support plate 13, the swing plate 15 is located between the driver 16 and the return spring 17. The negative pressure suction assembly includes a suction hood 20, a guide pipe 21, an impurity guide cavity 22, a suction fan 23, and a filter screen 24. The upper end of the suction hood 20 is connected to the impurity guide cavity 22 through the guide pipe 21. The bottom of the impurity guide cavity 22 is connected to the discharge port 4, and the left side is connected to the air inlet 3. The suction fan 23 is installed at the corner of the impurity guide cavity 22, and the filter screen 24 is set on the suction fan 23.

[0022] Further improvements, such as Figure 1 As shown, the horizontal plate 11 has a hollow structure and a partition plate 25 is provided in the middle. A cavity 26 is formed on the left side of the partition plate 25 and a cavity 27 is formed on the right side. The cavity 26 is connected to the guide pipe 21 and the impurity guide cavity 22 respectively. The cavity 27 is connected to the blower 19 and is used for airflow guidance.

[0023] Further improvements, such as Figure 2 and 3 As shown, the swing plate 15 includes a plate body 29 with several sets of air guide holes 28 evenly distributed on its surface and several sets of agitating brushes 30 evenly installed at the bottom of the plate body 29. The upper end of the air guide holes 28 is connected to the air vent 18. With this design, the cotton can be opened by agitating the brushes 30 and air can be appropriately introduced into the cotton through the air guide holes 28, so that the cotton is loosened and opened, which facilitates the subsequent negative pressure suction treatment of internal impurities.

[0024] Further improvements, such as Figure 3 As shown, the driver 16 includes a motor 31 and a rotating wheel 32 mounted on the power output end of the motor 31. A toggle block 33 is fixed on the edge of the rotating wheel 32. The toggle block 33 has a fan-shaped structure and one end is narrower than the other end. The motor 31 drives the rotating wheel 32 to rotate. During the rotation, the rotating wheel 32 drives the toggle block 33 to rotate synchronously and reciprocate in conjunction with the return spring 17.

[0025] Further improvements, such as Figure 5 As shown, the separator 9 includes a second motor 34 and a rotating rod 35 installed at the power output end of the second motor 34. Several sets of peeling rods 36 are evenly installed on the surface of the rotating rod 35. The peeling rods 36 have a rod-shaped structure and are used in conjunction with the toothed plate 8. The second motor 34 drives the rotating rod 35 to rotate counterclockwise, which separates the cotton on the saw tooth turning assembly and puts it into the discharge cavity 10 for external discharge.

[0026] Specifically, the suction hood 20 is set at an angle and is located at the upper left corner of the rotating roller 7. The lower end of the suction hood 20 has a suction port 37. The suction hood 20 can be used to perform negative pressure suction treatment on the impurities exposed inside the cotton.

[0027] In use: When cleaning cotton lint is required, the worker places the cotton lint on the conveyor 2, which feeds the cotton lint into the machine body 1 from the feed inlet 5. First, the motor 6 drives the rotating roller 7 to rotate counterclockwise. During the rotation, the toothed plate 8 flips the cotton lint counterclockwise along the rotating roller 7. When the cotton lint reaches the position of the swing-type airflow opening mechanism, the blower 19 guides the airflow into the cavity 27 and into the support plate 13 through the pipe. The airflow is appropriately introduced into the cotton lint through the air guide hole 28, causing the cotton lint to loosen and open. At the same time, the driver 16 actuates the swing plate 13 to swing, thereby agitating the fibers. Brush 30 separates the cotton lint, opening its interior. As it moves further, when it reaches the negative pressure suction assembly, the suction fan 23 applies negative pressure to remove any impurities that may be inside the cotton lint. The impurities are drawn along the suction hood 20, guide pipe 21, cavity 1 26, and impurity guide cavity 22, finally exiting through the left discharge port. After cleaning, when the cotton lint reaches the separator 9, motor 2 34 drives the rotating rod 35 to rotate counterclockwise, separating the cotton lint from the sawtooth turning assembly and sending it into the discharge cavity 10 for external discharge, thus achieving efficient cleaning of the cotton lint's interior.
