[0034] Implementation Method 1

[0035] Reference Figures 1 to 5 This embodiment is an optional embodiment of the present application, which discloses a waste cotton recycling system, including a waste cotton temporary storage box 1, the waste cotton temporary storage box 1 is an overall cylindrical structure, and its top is open, and a waste cotton grabbing module is also arranged on the waste cotton temporary storage box 1;

[0036] The waste cotton grabbing module includes a rotating arm 8, and a rotating shaft 9 and a rotating motor 10 connected in a power connection are arranged in the waste cotton temporary storage box 1. The rotating shaft 9 is coaxially arranged with the waste cotton temporary storage box 1, and the free end of the rotating shaft 9 is connected in power to the rotating arm 8, so that the rotating arm 8 is controlled to rotate around the axis of the waste cotton temporary storage box 1 by the driving motor 32;

[0037] At the same time, a support arm 12 is also provided at the free end of the rotating arm 8, and a walking roller 13 is provided at the bottom of the support arm 12. At the same time, a coaxial annular track is also provided around the outer side of the waste cotton temporary storage box 1, and the walking roller 13 is adapted to the annular slide rail 11;

[0038] In the above structure, the rotating arm 8 is controlled by the driving motor 32 to continuously rotate around the axis of the waste cotton temporary storage box 1, so as to realize uninterrupted extraction of waste cotton in different areas; on the one hand, it can help to ensure the balance of waste cotton temporary storage in different areas, while ensuring the stability and reliability of waste cotton transportation; on the other hand, the continuously moving rotating arm 8 can ensure operation in any area of ​​the waste cotton temporary storage box 1, which not only eliminates the need for manual sorting and adjustment, reduces labor consumption, but also helps to reduce the volume of the waste cotton temporary storage box 1.

[0039] Furthermore, a suction module is also provided on the rotating arm 8, and the suction module includes a suction hood 17, and the suction hood 17 is in a conical structure as a whole, and its large end is an inlet end 18, and its small end is an outlet end. The cross section of the inlet end 18 of the suction hood 17 is in a rectangular structure as a whole to increase the suction area, and the cross section of the outlet end is in a circular structure.

[0040] By setting the extraction hood 17 with a conical structure, on the one hand, the area of ​​the inlet end 18 can be expanded to ensure that the operating area is covered as much as possible at the same time. Optimally, the extraction hood 17 can cover the entire waste cotton temporary storage box 1 in the radial direction, thereby ensuring that the entire waste cotton temporary storage box 1 is covered within one rotation cycle, which helps to improve operating efficiency. At the same time, there is no need to set up a radial moving device, thereby simplifying the structure of the equipment. On the other hand, based on the Venturi effect, the setting of the conical structure can also increase the flow rate of the airflow at the outlet end, thereby ensuring the stable output of waste cotton.

[0041] Furthermore, a lifting motor 15 is also provided on the rotating arm 8, and the working end of the lifting motor 15 moves in the vertical direction. The working end of the lifting motor 15 is also connected to the lifting frame 14, and the extraction cover 17 is arranged on the lifting frame 14; preferably, a limit slide bar is also provided on the rotating arm 8, and the limit slide bar is slidably connected to the lifting frame 14;

[0042] The rotating arm 8 is also provided with a distance sensor 16 for detecting the position of the lifting frame 14;

[0043] Since the present application mainly extracts waste cotton by means of negative pressure suction, sufficient space must be reserved for air flow between the inlet end 18 of the extraction hood 17 and the top surface of the waste cotton. The height position of the lifting frame 14 can be monitored in real time through the distance sensor 16, so as to ensure that the end surface of the inlet end 18 of the extraction hood 17 and the material surface of the waste cotton temporary storage box 1 are always at a reasonable level; on the one hand, it can avoid the decrease in suction force caused by excessive gap, and on the other hand, it can ensure that the extraction force of the negative pressure suction force is reasonable, and does not affect the rotational movement of the rotating arm 8, thereby ensuring that the equipment is always in the best working condition.

[0044] Further, see Figure 5 , the lifting frame 14 is also provided with a waste cotton initial loosening device, which is arranged on the mounting frame along the rotation direction of the rotating frame, and a first rotating shaft 36 is rotatably arranged on the mounting frame, and a rotating motor 10 connected to the first rotating shaft 36 is also arranged on the mounting frame; along the axis of the first rotating shaft 36, a plurality of groups of grabbing hooks 37 are arranged on the first rotating shaft 36, and each of the grabbing hooks 37 in the same group is located on the same radial section, and each of the grabbing hooks 37 is radially arranged around the axis of the first rotating shaft 36;

[0045] The lifting frame 14 is also provided with an arc-shaped material guide plate 38 , which is located between the material extraction cover 17 and the first rotating shaft 36 . A plurality of stripping teeth 39 are also provided on the side of the material guide plate 38 facing the first rotating shaft 36 .

[0046] The stripping teeth 39 and the grabbing hooks 37 are arranged alternately;

[0047] When in use, the first rotating shaft 36 is controlled by the rotating motor 10 to rotate counterclockwise, and each of the grabbing hooks 37 can not only continuously hook the waste cotton but also loosen the top of the waste cotton. The hooked waste cotton gradually fits with the stripping teeth 39 as the first rotating shaft 36 rotates, and finally enters the extraction cover 17 from the guide plate 38.

[0048] In actual production, the compactness of waste cotton is much greater than that of new cotton, and there are also problems such as large changes in compactness, while the air flow velocity of the extraction is fixed, which causes the extraction flow rate of the waste cotton to be in a fluctuating state; as the spiral motor controls the rotation of the first rotating shaft 36, each of the grabbing hooks 37 can not only continuously hook up the waste cotton but also loosen the top of the waste cotton, thereby continuously forming a fluffy surface layer in the top area of ​​the waste cotton, reducing the difficulty of grabbing the waste cotton, which is beneficial to improving the stability of the waste cotton conveying flow rate; secondly, the fluffy waste cotton is easier to be extracted, which can effectively increase the conveying amount of the waste cotton, ensure that each device is in the best working condition, and improve the processing efficiency of the waste cotton.

[0049] Furthermore, the outlet end of the material extraction cover 17 is also connected to a material extraction fan 19, and the outlet end of the material extraction fan 19 is connected to the cotton distributor 2 through the cotton conveying pipe 3;

[0051] Further, the outer diameter of the first tube body 301 is smaller than the inner diameter of the second tube body 302, that is, the first tube body 301 is inserted into the second tube body 302, and a rolling bearing 303 is provided between the first tube body 301 and the second tube body 302;

[0052] In actual use, the first tube body 301 rotates with the rotating arm 8, while the second tube body 302 is in a stationary state, thereby ensuring the stability and reliability of the connection between the rotating arm 8 and the cotton dispenser 2 and avoiding interference between the states of the two.

[0053] Secondly, by controlling the diameters of the first tube body 301 and the second tube body 302 , waste cotton can be effectively prevented from entering the rolling bearing 303 , thereby ensuring stable operation of the equipment.

[0054] Furthermore, the cotton distributor 2 includes an adjustment box 22, and the adjustment box 22 is provided with a feed port 23 and a plurality of discharge ports 24, wherein the feed port 23 is connected to the outlet end of the second tank body;

[0055] An adjusting plate 25 is rotatably provided on each of the discharge ports 24, and a rotating shaft 9 is provided on the symmetric axis of each of the adjusting plates 25. Meanwhile, a plurality of servo motors 26 are also provided on the adjusting box 22, and each of the servo motors 26 is respectively connected to each of the rotating shafts 9;

[0056] The servo motors 26 can respectively and accurately control the rotation angle of each adjustment plate 25, thereby adjusting the opening and closing and the opening degree of each discharge port 24, so as to adjust the waste cotton conveying path and the conveying amount of different paths;

[0059] The metal fire detector 20 can detect sparks in the waste cotton flow, so that the fire source can be detected immediately to ensure the safe operation of the equipment, and the heavy object separator 21 can separate heavier debris such as metals in the waste cotton in time, thereby ensuring the smooth progress of the subsequent processes and effectively protecting the equipment.

[0060] Furthermore, each discharge port 24 of the regulating box 22 is connected to a cotton opening module through a pipeline, and the cotton opening module includes a chassis 27, and the chassis 27 is provided with a cotton inlet 28 and a cotton outlet 29;

[0061] The cotton inlet 28 is connected to the discharge port 24 of the regulating box 22 through a pipeline; a driving motor 32 is also provided at the bottom of the chassis 27, and a first roller 30 and a second roller 31 are also rotatably provided in the chassis 27, and the driving motor 32 is respectively connected to the first roller and the second roller 31 by power; along the axis direction of the first roller 30, a plurality of first beaters 33 are provided on the outer surface of the first roller 30, and each of the first beaters 33 is evenly divided into a plurality of groups, and each group of the first beaters 33 is arranged along the axis of the first roller 30, and each of the first beaters 33 in the same group is located on the same radial section and is arranged radially;

[0063] A plurality of second beaters 34 are arranged along the axis direction of the second roller 31. The second beaters 34 are also divided into a plurality of groups. The second beaters 34 of each group are arranged along the axis of the first roller 30. The second beaters 34 of the same group are located on the same radial section and are arranged radially.

[0064] Along the flow direction of the material, the first beaters 33 and the second beaters 34 are arranged alternately; each of the second beaters 34 is a corner nail.

[0065] At the same time, a slag discharge auger is also provided at the bottom of the chassis 27 . The slag discharge auger is located directly below the second roller 31 , and the slag discharge auger is connected to the driving motor 32 .

[0066] In the technical solution described in the present application, two beaters with different structures are provided, which cooperate with each other to realize the gradual opening and impurity removal of waste cotton, thereby improving the opening quality of waste cotton;

[0067] At the same time, the waste generated during the opening process can also directly fall to the bottom of the chassis 27 through the debris discharge hole 35, and finally be discharged through the auger.

[0068] Furthermore, the cotton opening module further comprises a cotton box and a cotton condenser, wherein the input end of the cotton condenser is connected to the cotton distributor, and the output end thereof is connected to the cotton box, and the outlet end of the cotton box is connected to the cotton inlet 28, and the cotton flow rate can be regulated and buffered by the cotton box, so that the cotton flow rate at the cotton inlet is more stable;

[0072] When in use, the waste cotton is evenly stacked in the waste cotton temporary storage box, and the driving motor controls the waste cotton grabbing module to rotate continuously, and the waste cotton enters the cotton conveying pipe by sucking air. During the grabbing process, as the height of the waste cotton continues to decrease, the lifting motor controls the entire waste cotton grabbing device to move downward, and then the waste cotton is distributed to different cotton opening modules through the cotton distributor, and is packaged by the baler after the cotton is opened;
