[0036] When one of the roller 17 rotates from outside to inside, since the end of each second shaft 20 away from the synchronous wheel 44 is fixedly connected with a fifth gear 45, the two fifth gears 45 are meshingly connected, so that the other roller 17 rotates from outside to inside, and then the regenerated polyester fibers previously put in are transported to the rotating drum 11 through the two rollers 17.

[0037] When the regenerated polyester fibers are transported to the inside of the processing box 10, they first fall on the outer wall of the rotating drum 11. At this time, the controller is started to start the direct current motor 29. Since the initial state, the output end of the direct current motor 29 is fixedly connected with the first gear 31, the second gear 32 is fixedly connected with the first shaft 15, the diameters of the first gear 31 and the second gear 32 are consistent, the third gear 33 and the fourth gear 34 are staggered, so as to drive the rotating drum 11 and the plurality of first nails 12 on the outer wall thereof to rotate clockwise, cooperate with the plurality of second nails 13 designed on the inner wall of the mounting chamber, effectively tear the fibers, so as to loosen them into smaller fiber bundles. At the same time, the rotating drum 11 can drive the plurality of first nails 14 to rotate clockwise. During the combing process, the plurality of first nails 14 can make the fibers gradually straighten and parallel, and remove part of the winding, lay a foundation for subsequent fine combing and yarn quality. At the same time, through the uniform grabbing and combing of the plurality of first nails 14, a fiber layer with more uniform thickness can be formed, which is beneficial to stable processing of subsequent processes and improves the yarn quality. During the opening process, impurities such as cotton seeds and sand in the fibers are separated from the opened fibers under the impact, throwing and centrifugal force of the plurality of first nails 14, and then discharged to the outside of the processing box 10 through the impurity removal hole 35 during the discharge process to the discharge port 23.

[0038] A camera (not shown in the figure) is installed above the discharge port 23 to monitor the state of the opened fibers in real time. When it is detected that the opened fiber bundles fail to be effectively decomposed into single fiber state, and white tight fiber bundles appear in the cotton roll or cotton layer, which will affect the subsequent drafting and yarn evenness. At this time, the micro motor 25 is started through the controller to drive the output end of the micro motor 25 to rotate the lead screw 24. Since the lead screw 24 is threadedly connected with the screw block 26, the screw block 26 is fixedly connected with the sliding plate 27, the sliding plate 27 is slidably connected with the two guide rails through the four slide columns 28, and the rotating assembly at the top of the sliding plate 27 is driven to slide to the end away from the processing box 10, that is, the third gear 33 is engaged with the fourth gear 34, and the first gear 31 and the second gear 32 are staggered. Since the diameter of the third gear 33 is greater than that of the fourth gear 34, the speed is increased, the rotating speed of the rotating drum 11 and the plurality of first angle nails 12 and the plurality of first carding needles 14 on the outer wall of the rotating drum 11 is further increased, the piercing and carding effect on the fibers is improved, the opening strength is improved, and the fiber clumping is prevented.

[0039] When the rotating drum 11 is switched, the sliding rod 36 is fixedly connected with one end of the L-shaped plate, the sliding rod 36 is slidably connected with the outer wall of the processing box 10, the push plate 37 is fixedly connected with the end of the sliding rod 36 away from the L-shaped plate, the first inserting rod 38 is fixedly connected with the end of the push plate 37 away from the sliding rod 36, the L-shaped rotating rod 40 is rotatably connected with the processing box 10 through a rotating shaft, the second inserting rod 39 is fixedly connected with the top end of the surrounding plate 16, the first inserting rod 38 and the second inserting rod 39 are respectively inserted into the two insertion slots, the surrounding plate 16 is slidably connected with the feeding port 18 through the four slide blocks 19, and the pressing of the second inserting rod 39 is realized through the rotation of the L-shaped rotating rod 40, so that the two roller rollers 17 at the bottom of the surrounding plate 16 are further driven to vertically descend, that is, the distance between the two roller rollers 17 and the rotating drum 11 is reduced, the holding force on the fiber bundle is improved, the opening strength is improved, and the first angle nails 12 and the first carding needles 14 on the surface of the rotating drum 11 can be inserted deeper into the fiber layer, so that the protruding, loose and short fibers in the held fiber bundle are selectively grabbed and pulled out, the whole bundle is prevented from slipping, and the change from “bundle tearing” to “fine grabbing” is realized.

[0040] When the surrounding plate 16 drives the two roller rollers 17 to vertically descend, the four reset springs 41 are changed from the initial state to the tight state, and when the surrounding plate 16 is reset, the four reset springs 41 are changed from the tight state to the initial state, which supports the surrounding plate 16 and improves the installation stability of the surrounding plate 16.

When the electric push rod 60 is started through the controller, the output end of the electric push rod 60 is extended. Since the adjusting plate 51 and the supporting plate are hingedly connected with the two ends of the electric push rod 60 respectively, the adjusting plate 51 is rotatably connected with the supporting ring through a bearing, and the supporting plate is fixedly connected with the first rotating shaft 15, so as to drive the adjusting plate 51 to rotate in a circular manner with the first rotating shaft 15 as the center. Since each slide rail 52 is fixedly connected with the supporting plate, each sliding bar 53 is slidably connected with one slide rail 52, and each third inserting rod 54 is fixedly connected with one sliding bar 53, the outer wall of the adjusting plate 51 is provided with a plurality of arc-shaped grooves 55 at equal intervals, and each third inserting rod 54 is inserted into one arc-shaped groove 55. In this way, the resistance force generated by the plurality of arc-shaped grooves 55 on the plurality of third inserting rods 54 when the adjusting plate 51 rotates is converted into the pushing force on the plurality of sliding bars 53, that is, the plurality of sliding bars 53 are driven to move away from each other.
