[0035] In some embodiments, when the device is in operation, the operator puts the regenerated slice into the filament preparation bin 3 through the feeding port 301, and the regenerated slice cut into filaments falls into the crimping bin 2 below. Under the action of the first flow guide cover 203 and the second flow guide cover 206, the regenerated slice filaments fall into the upper. Under the action of the driving swing arm 208 and the driven swing arm 207, the crimping bin 2 rotates in a circumferential direction relative to the workbench 1, and at this time, under the linkage cooperation of multiple groups of fan blades 205, the regenerated slice filaments are double kneaded and crimped. When the crimping processing is completed, the discharging motor 119 is started. When the discharging tooth ring 109 drives the abutment plate 110 to rotate, the first sealing member 115 is extruded and retracted into the first lifting cavity 113, and the second sealing member 118 is extruded and retracted into the second lifting cavity 116, at this time, the regenerated slice filaments after crimping processing fall onto the discharging mechanism 121 below through the first through hole 111 and the second through hole 112.

[0039] In some embodiments, in order to synchronize the driving of the two sets of shearing rollers 302 to rotate towards the middle, thereby cutting the regenerated sheet into shreds, intermeshing gear teeth 305 are designed.

[0040] In some embodiments, a power device is further included, and an output end of the power device is connected with one of the rotating shafts 304.

[0041] Referring to Figure 3 , the end of the kneading bin 202 away from the direction of gravity is provided with a conical first flow guide 203, the first flow guide 203 is internally provided with a kneading motor 204, and a fan blade 205 is installed at the output end of the kneading motor 204; the end of the shunt bin 201 away from the direction of gravity is provided with a conical second flow guide 206.

[0042] In some embodiments, after the regenerated sheet is cut into shreds, it falls into the curling bin 2 below. Since the arc plates 103 are circumferentially distributed at the edge of the curling cavity 102, in order to improve the curling efficiency, a second flow guide 206 is designed to guide the cut shreds onto the arc plates 103.

[0043] In some embodiments, in order to further improve the curling efficiency, a plurality of kneading motors 204 are designed. When the curling bin 2 moves circumferentially relative to the curling cavity 102, the plurality of fan blades 205 also rotate, thereby further shortening the curling time through the double extrusion and kneading structure.

[0044] In some embodiments, the fan blade 205 is made of flexible material.

[0045] Referring to Figures 3-5 , the outer wall of the curling bin 2 is provided with a plurality of driven swing arms 207, the end of the driven swing arm 207 away from the curling bin 2 is movably installed with a driving swing arm 208; the end of the driving swing arm 208 away from the driven swing arm 207 is provided with a mounting shaft 209 facing the direction of gravity, the mounting shaft 209 penetrates through the workbench 1, and the driving swing arm 208 is movably installed on the top of the workbench 1 through the mounting shaft 209.

[0046] In some embodiments, when the driving motor 107 is started, the plurality of driven swing arms 207 rotate synchronously, and drive the driving swing arm 208 and the curling bin 2 to move circumferentially relative to the workbench 1.

[0047] Referring to Figures 5-6A linkage gear 210 located inside the workbench 1 is installed on the mounting shaft 209, and a double gear ring 106 is movably installed on the inner wall of the workbench 1 on the side away from the direction of gravity; the workbench 1 also includes a drive motor 107, and a curling gear 108 is installed at the output end of the drive motor 107. The linkage gear 210 and the curling gear 108 are located on both sides of the double gear ring 106 and are both engaged with the double gear ring 106.

[0048] In some embodiments, a double gear ring 106 is provided to synchronously drive the plurality of linkage gears 210 to rotate, thereby causing the crimping chamber 2 to move circumferentially relative to the workbench 1. Under the squeezing and kneading action of the arc plate 103, the regenerated thin filaments are rapidly crimped.

[0049] See Figure 6 A track 123 is provided on the side of the double-toothed ring 106 facing away from the direction of gravity, and a mounting groove 124 is provided on the inner wall of the workbench 1 facing away from the direction of gravity. The double-toothed ring 106 is movably mounted inside the workbench 1 through the mounting groove 124.

[0050] In some embodiments, the double gear ring 106 synchronously drives the linkage gear 210 and the curling gear 108. In order to install the double gear ring 106 and ensure stability during rotation, a track 123 and a mounting groove 124 structure that cooperate with each other are designed.

[0051] See Figures 4-5 A first feeding port 104 that is intermittently opened is provided between two adjacent arc plates 103, and a plurality of second feeding ports 105 that are intermittently opened are also provided on the inner wall of the curling cavity 102 facing the direction of gravity; a feeding gear ring 109 is movably installed on the radial outer wall of the curling cavity 102, and a contact plate 110 that is in contact with the axial outer wall of the curling cavity 102 is provided in the middle part of the feeding gear ring 109; a plurality of first through holes 111 that are intermittently connected to the first feeding port 104, and a plurality of second through holes 112 that are intermittently connected to the second feeding port 105 are provided on the abutment plate 110; a first sealing member 115 that blocks the first feeding port 104 can be telescopically installed between two adjacent first through holes 111, and a second sealing member 118 that blocks the second feeding port 105 can be telescopically installed between two adjacent second through holes 112.

[0052] In some embodiments, when the discharge gear ring 109 drives the abutment plate 110 to rotate, the first sealing member 115 is squeezed and retracted into the first lifting chamber 113, at which point the first discharge port 104 communicates with the first through-hole 111. The second sealing member 118 is squeezed and retracted into the second lifting chamber 116, at which point the second discharge port 105 communicates with the second through-hole 112. The crimped regenerated filaments pass through the first through-hole 111 and the second through-hole 112 and fall onto the discharge mechanism 121 below.

[0053] Referring to Figures 4-7 The abutment plate 110 is provided with a plurality of first lifting cavities 113 between the first through holes 111, and the first lifting cavities 113 are connected with first reset members 114. The first sealing members 115 are connected to one end of the first reset members 114 away from the direction of gravity. The abutment plate 110 is provided with a plurality of second lifting cavities 116 between the second through holes 112, and the second lifting cavities 116 are connected with second reset members 117. The second sealing members 118 are connected to one end of the second reset members 117 away from the direction of gravity.

[0054] In some embodiments, when the curling processing of the regenerated flake filaments is completed, the abutment plate 110 is rotated by the blanking tooth ring 109. The first sealing members 115 are extruded and retracted into the first lifting cavities 113, and the first reset members 114 are compressed at this time. The second sealing members 118 are extruded and retracted into the second lifting cavities 116, and the second reset members 117 are compressed at this time.

[0055] In some embodiments, when the discharging is completed, the abutment plate 110 is rotated by the blanking tooth ring 109. When the first sealing members 115 rotate to the position of the first blanking port 104, the first sealing members 115 are automatically popped up and blocked the first blanking port 104 under the action of the first reset members 114. When the second sealing members 118 rotate to the position of the second blanking port 105, the second sealing members 118 are automatically popped up and blocked the second blanking port 105 under the action of the second reset members 117.

[0056] In some embodiments, the first reset members 114 and the second reset members 117 have strong elasticity. In the natural state or during kneading, the first sealing members 115 and the second sealing members 118 will not retract into the first lifting cavities 113 and the second lifting cavities 116.

[0057] In some embodiments, the first sealing members 115 and the second sealing members 118 are both provided with a rounded corner structure. This design can ensure that the first sealing members 115 and the second sealing members 118 can be stored and retracted in the direction perpendicular to the gravity when the abutment plate 110 rotates.

[0061] In some embodiments, after the curling processing of the regenerated flake filament is completed, the cutting device 122 is designed to further adjust the length of the flake filament according to requirements.

[0062] Referring to Figure 1 and Figure 4 The workbench 1 is further provided with a control panel 101.

[0063] In some embodiments, the control panel 101 is designed to facilitate the operator to control the operation of the device.

[0064] In some embodiments, the inner wall of the curling cavity 102 is further provided with a plurality of heating pipe structures (not shown), which can heat while kneading during the curling processing, thereby further improving the curling efficiency.

[0065] The technical features of the above embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not contradict, they should be considered as the scope of the description.
