[0026] The screening assembly 1 includes a screening bin 101, a separation rod 102, a mounting plate 103, a vibrating screen plate 104, a vibration motor 105, a movable push plate 106, a cylinder 107 and a discharge chute 108. The screening bin 101 is fixedly connected to the top of the support frame 2, the separation rod 102 is fixedly connected to the inside of the screening bin 101, the mounting plate 103 is installed at both ends inside the screening bin 101, the vibrating screen plate 104 is fixedly connected to the bottom of the mounting plate 103, the vibration motor 105 is screwed to the outside of the screening bin 101, the movable push plate 106 is arranged on the outside of the separation rod 102, the cylinder 107 is screwed to one side of the screening bin 101, and the discharge chute 108 is opened on the side of the screening bin 101 away from the cylinder 107. The separated materials enter the inside of the screening bin 101, and the ordinary cloth, buttons, etc. are initially screened by the separation rod 102. The cloth is separated and falls on the vibrating screen plate 104. Then the vibrating motor 105 drives the vibrating screen plate 104 to vibrate, and granular and block-like items such as buttons and zippers are screened. The movable push plate 106 is driven by the cylinder 107 to push the cloth from the discharge trough 108 to the collecting bin 4 for screening, thereby reducing the workload of manual screening. The size of the plate body 110 is consistent with the size of the inner wall of the sub-screening bin 101, so it can cover the inside of the sub-screening bin 101, and push the auxiliary materials in the sub-screening bin 101 into the collecting bin 4. The separation rods 102 are grouped into two and are evenly distributed above the inside of the sub-screening bin 101, ensuring that the cloth strips and block-like auxiliary materials can be well separated. An inclined plate is provided at the bottom of the discharge trough 108, and the inclined plate is inclined toward the inside of the collecting bin 4, so that auxiliary materials such as cloth can fall onto the top of the second conveyor belt 5.
[0027] The movable push plate 106 includes a plate body 110, a cleaning mechanism 111, a bottom push plate 112 and a cleaning rotating tube 113.

[0029] The crushing head 120 includes a housing 130, a fixed shaft 131, a first crushing roller 132, a second crushing blade 133, a connecting block 134 and a first transmission belt 135. The housing 130 is fixedly connected to one end of the driving block 121, the fixed shaft 131 is fixedly connected to the inside of the housing 130, the first crushing roller 132 is rotatably connected to the inside of the fixed shaft 131, the second crushing blade 133 is fixedly connected to one end of the first crushing roller 132, the connecting block 134 is fixedly connected to one end of the second crushing blade 133, and the first transmission belt 135 is connected to the first crushing roller 132. A transmission belt 135 is sleeved and connected to the outside of the connecting block 134. The first transmission belt 135 drives the connecting block 134 to rotate, so that the connecting block 134 drives the second crushing blade 133 and the first crushing roller 132 to rotate, and the cloth entering the crushing head 120 is crushed. After the double crushing by the first crushing roller 132 and the second crushing blade 133, the cloth is discharged from the cloth trough provided at the bottom of the shell 130. For the cloth strips not wound around the separation rod 102, the push plate 106 can be moved to push the cloth strips off.
[0030] The driving block 121 includes a protective block 140, a driving motor 141, a heat dissipation groove 142, a mounting frame 143, a fan 144, a rotating circle 145 and a second transmission belt 146. The protective block 140 is fixedly connected to the inside of the plate body 110, the driving motor 141 is fixedly connected to the inside of the protective block 140, the heat dissipation groove 142 is opened on both sides of the protective block 140, the mounting frame 143 is fixedly installed on one side of the driving motor 141, the fan 144 is arranged inside the mounting frame 143, the rotating circle 145 is rotatably connected to one end inside the protective block 140, the second transmission belt 146 is sleeved and connected to the outside of the rotating circle 145, and the output shaft of the driving motor 141 is sleeved and connected to the inside of the other end of the second transmission belt 146. Therefore, the driving motor 141 can drive the crushing head 120 to work. Through the action of the fan 144 and the heat dissipation groove 142, the heat generated by the driving motor 141 working in the protective block 140 can be discharged, thereby extending the service life of the heat dissipation groove 142.
[0031] The fixed rotating shaft 131 includes a tube body 150 and a rotating rod 151. The tube body 150 is fixedly connected to the inside of the outer shell 130, and the rotating rod 151 is rotatably connected to the inside of the tube body 150. The outside of the first crushing roller 132 is rotatably connected to the rotating rod 151, so that the first crushing roller 132 can rotate within the fixed rotating shaft 131, thereby crushing and cleaning the cloth strips wrapped around the separation rod 102.
[0032] In summary, when the device is in use, the auxiliary material is poured into the interior of the screening bin 101, separated by the separation rod 102, and then falls on the vibrating screen plate 104, the vibration motor 105 is started, driving the vibrating screen plate 104 to vibrate, and the auxiliary material is separated, and then the cylinder 107 is started, driving the moving push plate 106 to move in the screening bin 101, pushing the auxiliary material on the vibrating screen plate 104, allowing the auxiliary material to fall into the collecting bin 4, and the separated auxiliary material is transported to the next production link through the action of the first conveyor belt 3 and the second conveyor belt 5.
[0033] When auxiliary materials fall into the screening bin 101, the separation rod 102 may be entangled with cloth strips, thread ends, etc., which are difficult to clean. Therefore, when the push plate 106 is moved, the driving motor 141 is started, thereby driving the rotating circle 145 to rotate. The rotating circle 145 is fixedly connected to the connecting block 134, thereby driving the connecting block 134 to rotate, so that the fixed rotating shaft 131 and the second crushing blade 133 rotate, and the cloth strips and thread ends wrapped around the separation rod 102 are cut, reducing the work of manual cleaning.
