[0037] S1. Hang the feeding ton bag 102 in the frame member 101 in the feeding device 100, open the bag mouth and feed the material into the feeding hopper 104, use the material-moving rod 701 and the downward moving member 704 in the unloading mechanism 700 to move and unload the material downward, and quickly unload the waste fibers at the bag mouth to avoid the waste fibers from being blocked at the bag mouth of the feeding ton bag 102. The unloading mechanism 700 can assist the unloading of the waste fibers during the feeding process, and the waste fibers will not block the bag mouth and cause intermittent unloading, thereby ensuring the continuity of the feeding of the waste fibers, and relatively leveling the unloaded waste fibers, so that the amount of waste fibers entering the crushing device later is uniform and convenient for being fully crushed, thereby improving the efficiency of the waste fiber crushing processing;

[0038] S2, when the waste fibers are fed into the feeding hopper 104, the waste fibers in the feeding hopper 104 are assisted to be fed onto the flat conveyor 103 by using the feeding rod 701 and the feeding hook 706, and then the waste fibers on the flat conveyor 103 are fed to be relatively flat and uniform by using the leveling member 705, so that the subsequent waste fibers can be uniformly fed into the primary crushing device 200, and the waste fibers fed are uniformly crushed more uniformly;

The material shifting hook 706 and the material shifting rod 701 form a vertical upward arrow structure. The material shifting hook 706 moves upward and extends into the feeding ton bag 102, which is not easy to hang on the waste fibers. The material shifting hook 706 moves downward, and can hook the waste fibers below the material shifting hook 706 downward out of the bag opening, which is convenient for rapid unloading of the waste fibers.

[0042] In this embodiment, preferably, a supporting cross plate 707 is horizontally arranged at the lower end of the material shifting rod 701, which passes through the feeding hopper 104 and is exposed to the outside. A vertical rectangular hole is arranged on the side of the feeding hopper 104. The supporting cross plate 707 passes through the vertical rectangular hole. The front and rear surfaces of the supporting cross plate 707 fit the inner wall of the vertical rectangular hole. The two cooperate to limit the front and rear directions of the supporting cross plate 707 without affecting the upward or downward movement of the supporting cross plate 707. In addition, elastic filling blocks 708 for filling the inner wall of the vertical rectangular hole are arranged on the upper and lower surfaces of the supporting cross plate 707. The filling blocks 708 can be sponge blocks, which do not affect The support cross plate 707 can move and fill the gap of the vertical rectangular hole to reduce the discharge of waste fibers. The right end of the support cross plate 707 is connected to the piston rod inside the driving cylinder 703. A stand 1041 is provided on the side of the feeding hopper 104 to support the feeding hopper 104. A certain space is left between the feeding hopper 104 and the flat conveyor 103 to facilitate the outward transportation of the waste fibers fallen on the flat conveyor 103. A side mounting frame 702 is provided on the right side of the stand 1041 to support the driving cylinder 703. The side mounting frame 702 is a bow-shaped frame to facilitate the installation of the driving cylinder 703.

The upper surface of the fixed wedge block 7042 is also provided with a mounting slide 7043 and a limit bolt mounted on the fixed vertical plate 7044, which is convenient for adjusting the matching distance between the fixed wedge block 7042 and the isosceles wedge block 7041, convenient for adapting to the size of the bag opening, and convenient for supporting the horizontal plate 707 to move to a certain position and then move downward.

[0044] In this embodiment, preferably, a reset member 709 is provided between the driving cylinder 703 and the side mounting frame 702. The reset member 709 can be used to reset after the support cross plate 707 moves downward, so that the material-dispensing rod 701 and the material-dispensing hook 706 move downward and then move upward to re-extend into the feeding ton bag 102. The reset member 709 includes a support seat 7091 sleeved on the driving cylinder 703, and a side bottom plate 7092 located below the support seat 7091 is provided on the right side of the side mounting frame 702. Two limit stops are provided above the side bottom plate 7092. Bottom rail 7093, the limiting bottom rail 7093 is symmetrically located at the front and rear of the driving cylinder 703, a telescopic column 7094 is arranged between the limiting bottom rail 7093 and the side bottom plate 7092, the telescopic column 7094 can be retracted under pressure, a reset member 7095 is sleeved on the telescopic column 7094, the upper and lower ends of the reset member 7095 are respectively fixed on the surface of the side bottom plate 7092 and the limiting bottom rail 7093, the support seat 7091 is slidably sleeved on the limiting bottom rail 7093, and the support seat 7091 cooperates with the limiting bottom rail 7093 without limiting the movement of the supporting cross plate 707.

[0045] In this embodiment, preferably, a leveling component 705 for leveling the waste fibers on the surface of the flat conveyor 103 is provided below the feeding hopper 104. The leveling component 705 can be used to drive the deflection plate 7055 and the leveling column 7056 to rotate back and forth on the flat conveyor 103 while the leveling rod 701 moves left and right to assist in unloading, so that the waste fibers piled on the flat conveyor 103 are spread outward and leveled. The waste fibers are relatively uniform on the flat conveyor 103, so that they can be evenly fallen into the crushing device for crushing. The leveling component 705 includes a fixed top plate 7052 fixed to the front surface of the fixed vertical plate 7044, and a rotatable rotating shaft 7053 is embedded in the fixed top plate 7052. The rotating shaft 7053 The upper sleeve is provided with a deflection gear 7054, and the deflection gear 7054 is located on the right side of the feeding hopper 104. A U-shaped frame 7051 cooperating with the deflection gear 7054 is provided on the lower surface of the supporting cross plate 707. The front surface of the horizontal end of the U-shaped frame 7051 is provided with teeth meshing with the deflection gear 7054.

[0046] In summary, when in use, the feeding ton bag 102 is hung on the frame member 101 through the existing hooks, etc., and is located above the feeding hopper 104. When the bag mouth is opened, the material removal rod 701 and the uppermost material removal hook 706 are located in the bag mouth of the feeding ton bag 102. During the feeding process, the driving cylinder 703 is operated. When the piston rod inside the driving cylinder 703 is extended, the supporting cross plate 707 is driven to move to the left, so that the material removal rod 701 moves to the left. The movement of the material removal rod 701 will allow the waste textile fibers in the bag mouth and the feeding hopper 104 to move. The isosceles wedge 7041 moves to the fixed wedge 7042 on the left, and the inclined surfaces of the two fit together. As the supporting cross plate 707 continues to move, the isosceles wedge 7041 moves downward along the inclined surface, and the supporting cross plate 707 and the downward moving driving cylinder 703, the material-dispensing rod 701 and the material-dispensing hook 706 move downward, which has the effect of pressing the waste fibers in the bag mouth and the feeding hopper 104 downward, allowing the waste fibers to be discharged. The bag 7091 moves downward from the bag opening and from the feeding hopper 104 to the flat conveyor 103. When the driving cylinder 703 moves downward, the supporting seat 7091 moves downward, the limiting bottom rail 7093 moves downward, the telescopic column 7094 contracts, the reset member 7095 compresses, and an upward reset trend is generated. When the piston rod in the driving cylinder 703 retracts, the supporting cross plate 707 moves leftward, the isosceles wedge block 7041 moves leftward and separates from the fixed wedge block 7042 on the left, and the reset member 7095 recovers its elasticity and drives the driving cylinder 703 to move downward. The movable cylinder 703, the supporting cross plate 707 and the material shifting rod 701 move upward and extend into the bag opening, and the isosceles wedge block 7041 moves to the right to cooperate with the fixed wedge block 7042 on the right, and the waste fibers are shifted to the right again while being pressed downward. As the supporting cross plate 707 moves left and right, the material shifting rod 701 and the material shifting hook 706 shift and press the materials left and right in the bag opening and the feeding hopper 104, which increases the convenience and continuity of the waste fiber unloading, does not interrupt the unloading, and improves the crushing efficiency of the waste fibers.

[0047] Embodiment 2

[0048] Reference Figure 7 and Figure 8 , which is the second embodiment of the present invention.

[0049] In this embodiment, preferably, the frame member 101 includes a top frame 1011, and the feeding ton bag 102 is suspended on the top frame 1011. A lower support leg 1012 is provided on the lower surface of the top frame 1011, and a fixed support leg 1014 is provided on the outer side of the lower support leg 1012, and an adjusting cylinder 1013 is provided on the inner side of the fixed support leg 1014. The piston rod inside the adjusting cylinder 1013 is fixed to the outer side of the lower support leg 1012, and the height of the top frame 1011 can be adjusted to facilitate adaptation to feeding ton bags 102 of different sizes and to facilitate the bag mouth of the feeding ton bag 102 to extend into the feeding hopper 104.

[0050] In the present embodiment, preferably, a bag opening adjustment mechanism 800 is provided on the outer side of the two fixed legs 1014 on the same side. The bag opening adjustment mechanism 800 can be used to change the size of the bag opening according to the feed amount requirement of the crushing device, thereby adjusting the discharge amount of the bag opening of the feeding ton bag 102, avoiding the situation where too much waste textile fiber is discharged and affecting the sufficient crushing, increasing the convenience of waste textile fiber discharge and crushing and improving the crushing effect. The two bag opening adjustment mechanisms 800 are relatively located on both sides of the bag opening, and the bag opening adjustment mechanism 800 includes a mounting cross plate 802 longitudinally located between the two fixed legs 1014 on the same side, and a telescopic cylinder 801 connected to the mounting cross plate 802 is provided on the side of the fixed legs 1014. A bidirectional screw rod 804 is arranged above the mounting cross plate 802, and a stabilizing seat for supporting the bidirectional screw rod 804 is arranged at the center of the upper surface of the mounting cross plate 802, and a bearing is embedded between the stabilizing seat and the bidirectional screw rod 804, and two clamping plates 803 for clamping the bag opening are sleeved on the bidirectional screw rod 804, and the left ends of the two clamping plates 803 are located at the front and rear surfaces of the bag opening, and the clamping plates 803 are threadedly connected with the bidirectional screw rod 804, and a driving motor 806 connected to one end of the bidirectional screw rod 804 is arranged on the upper surface of the mounting cross plate 802, which can drive the bidirectional screw rod 804 to rotate, and a limited sliding hole is provided on the surface of the mounting cross plate 802, and a guide slider 805 cooperating with the limited sliding hole is provided on the lower surface of the left end of the clamping plate 803.

[0051] In summary, when in use, the two bag opening adjustment mechanisms 800 can completely clamp the bag opening of the feeding ton bag 102. When the bag opening needs to be opened, the driving motor 806 drives the bidirectional screw rod 804 to rotate, driving the two clamping plates 803 to move slightly back and forth to reduce the clamping force on the bag opening, and the telescopic cylinder 801 works, and the piston rod inside the telescopic cylinder 801 retracts, driving the mounting cross plate 802 to move to the left, and the clamping plate 803 to move to the left. The distance between the clamping plates 803 in the two bag opening adjustment mechanisms 800 gradually increases. When the distance is appropriate, the driving motor 80 6 drives the bidirectional screw rod 804 to reverse, and the two clamping plates 803 move relatively to clamp the bag opening tightly. After clamping, the telescopic cylinder 801 works again, and the piston rod inside the telescopic cylinder 801 in the two bag opening adjustment mechanisms 800 moves to the left again, and the bag opening of the feeding ton bag 102 moves relatively for a distance, and the unobstructed bag opening is relatively moved and opened, so that the upper end of the material-moving rod 701 can be conveniently extended into the bag opening, and the size of the bag opening can be adjusted. When you do not want to unload the material, use the clamping plate 803 to clamp the bag opening to stop unloading, thereby increasing the convenience of unloading waste spinning fibers.

[0057] In summary, the materials discharged from the secondary crushing device 600 fall on the rotating screen 902 and the flat screen 901. When the rotating screen 902 is not located at the guide inclined plate 904, the rotating screen 902 and the flat screen 901 are both horizontally in the support plate 903. As the reciprocating cylinder 905 works, the piston rod inside the reciprocating cylinder 905 is extended and retracted, driving the rotating screen 902 and the flat screen 901 to move a certain distance left and right, so that the materials inside the two are slightly shaken, so that qualified materials can be quickly dropped and collected. For unqualified materials retained on the upper surfaces of the rotating screen 902 and the flat screen 901, the extension stroke of the piston rod inside the reciprocating cylinder 905 can be increased to make the retained materials on the upper surfaces of the rotating screen 902 and the flat screen 901 shake a larger distance. During the left and right shaking process, the materials will shake to the rotating screen The material on the rotating screen 902 will fall into the collection box arranged laterally. After the collection is completed, the piston rod inside the discharge cylinder 907 will retract, driving the flat screen 901 and the rotating screen 902 to move to the left. The rotating screen 902 will gradually become horizontal and can be relocated under the lower hopper to screen the material, thereby increasing the convenience of screening and collecting the crushed materials.
