Example 2:

[0035] Please see Figures 1-6The present invention discloses a cotton core crushing and laying mechanism and its cotton laying method based on a rotary cutting blade assembly. Compared with Embodiment 1, this embodiment further includes: a cotton laying assembly 5 comprising a second adjusting arm 51 fixedly mounted on the top of the machine base 1 by bolts and having an adjusting function; an L-shaped frame 52 fixedly mounted on the rear end of the second adjusting arm 51 by bolts; a third motor 53 having a driving function fixedly mounted on the side of the L-shaped frame 52 by bolts, and a second guide rod 54 inserted and fixedly connected to the end of the transmission shaft on the side of the third motor 53; a second rotary joint 55 having a guiding function inserted and fixedly connected to the side of the second guide rod 54; and a collar assembly 56 fixedly mounted on the top of the L-shaped frame 52.

[0036] The second rotary joint 55 on the side of the second guide rod 54 is connected to the first rotary joint 364 via a connecting pipe, and the first rotary joint 364, the second rotary joint 55, and the connecting pipe are also equipped with an air pump with a guiding function.

[0037] The collar assembly 56 includes an open ring 561 fixedly mounted on an L-shaped frame 52; an inner groove is provided on the top side inside the open ring 561, and a coil assembly 562 is fixedly mounted in the inner groove; a limit wire 563 is slidably provided inside the coil assembly 562, and the limit wire 563 is slidably positioned in the inner groove of the open ring 561; a tension spring 564 with a reset function is fixed to the left and right ends of the limit wire 563, and the tension spring 564 is fixed to the inner groove wall of the open ring 561; a microporous cover 565 with a filtering function is magnetically fixed to the outside of the limit wire 563.

[0038] The coil group 562 in the inner groove of the open ring 561 has a figure-eight structure, and C-shaped limiting wires 563 are provided on both the left and right sides of the open ring 561 and the coil group 562.

[0039] The working principle of the cotton core crushing and laying mechanism and its cotton laying method based on the above-mentioned rotary cutting blade assembly is as follows:

[0040] First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation.

[0041] Secondly, the cotton core is first fed by the placement roller 4, and then the distance between the cutting assembly 3 and the cotton core is adjusted by the lifting action of the lifting column 2. Then, the control cabinet 6 controls the second motor 39 to drive the reduction gear set 37 to reduce speed and drive multiple sets of adjusting blade shafts 35 to rotate synchronously to adjust the blade angle, thereby changing the cutting angle of the blade. Then, the first motor 33 drives the cutting blade holder 34 and the adjusting blade shafts 35 to rotate, and under the adjustment action of the lifting column 2, the directional and quantitative rotary cutting action of the cotton core is realized. Here, the second motor 39 and the second coil bearing 361 are simultaneously energized to make the cutting action possible. The blade holder 34, the rotating blade holder 362, and the first guide rod 363 achieve differential rotation. The air pump installed on the side of the first rotary joint 364 creates a relatively low-pressure air environment around the rotating blade holder 362 and the first guide rod 363. This causes the small pieces of cotton core after cutting to enter the interior of the rotating blade holder 362 due to the air pressure. Here, the small pieces of cotton core are cut and crushed again by the protrusions 366 on the inner wall and surface of the rotating blade holder 362. Then, the cotton core material that has been cut twice enters the first guide rod 363 through the opening slot 365 due to the air pressure. It is then transported to the interior of the second rotary joint 55 and the second guide rod 54 through the first rotary joint 364 on its side and related connecting pipes.

[0042] Third, the second guide rod 54 is rotated by the third motor 53. The air pump draws air in from the first guide rod 363, passes through the first rotary joint 364 and the second rotary joint 55 and the connecting pipe, and is then blown out from the second guide rod 54. As the second guide rod 54 rotates, the cotton core fragments are blown out by the airflow and gather inside the microporous cover 565. Here, the energization of the coil group 562 can be controlled, and when the cotton core fragments partially block the microporous cover 565, the distance between the second guide rod 54 and the microporous cover 565 can be adjusted under the influence of the airflow. The adjustable structure can change the thickness of the cotton core fragments. Then, under the rotation of the second guide rod 54 and the airflow guidance, the cotton core fragments gathered inside the microporous cover 565 are blocked by the L-shaped frame 52 and fall below the L-shaped frame 52. Then, the cotton core fragments are laid out under the adjustment action of the second adjusting arm 51.

[0043] This invention provides an improved cotton core crushing and laying mechanism and its laying method based on a rotary cutting blade assembly. By setting up a synergistic design of differential cutting of the cutting component 3 and the laying component 5 and instant air pressure adsorption, the problem of fiber entanglement during cotton core crushing is effectively solved, achieving efficient and fine crushing. Furthermore, with the help of a closed airflow conveying system and an electromagnetically controlled microporous cover, the lossless conveying of materials and the dynamic and precise adjustment of the laying thickness are achieved.
