[0044] like Fig. 9 As shown, a base 27 is fixedly connected to the middle of the bottom of the second track 191 , and a vibrator 28 is installed on the base 27 . The vibration direction of the vibrator 28 is parallel to the axial direction of the buffer device 18 .

[0045] The driving motor 7 , the fan 16 , the stepping motor 24 , and the vibrator 28 are electrically connected to the controller, so as to realize the control of the working states of the driving motor 7 , the fan 16 , the stepping motor 24 , and the vibrator 28 .

[0046] Working principle: The staff moves the position of the second sub-screen plate 26 to the bottom of the hopper 5, starts the drive motor 7, makes the drive motor 7 rotate clockwise, the driving shaft 8 starts to rotate, and the first cutting roller 9 starts to rotate at the same time. The driving shaft 8 transmits power to the gear box 10, and the gear box 10 outputs power to the driven shaft 11. The driven shaft 11 rotates counterclockwise, driving the second cutting roller 12 to rotate counterclockwise, and the non-woven fabric is transported to the inside of the hopper 5. The blades on the first cutting roller 9 and the second cutting roller 12 crush the non-woven fabric, and the crushed non-woven fabric falls on the second sub-screen plate 26.

[0047] Start the vibrator 28, and the vibrator 28 begins to vibrate, driving the first track 19, the second track 191, the first sub-sieve plate 25, and the second sub-sieve plate 26 to vibrate, and the guide sleeve 182 moves up and down on the guide column 181 according to the frequency of the vibration; after the second sub-sieve plate 26 is shaken, small pieces of non-woven fabric are shaken off the second sub-sieve plate 26, leaving large pieces of fabric on the second sub-sieve plate 26.

[0048] At this moment, the stepper motor 24 is started to rotate forward, driving the lead screw 21 to rotate, driving the first sub-screen plate 25 and the second sub-screen plate 26 to move forward. Fig.10 As shown, when the first sub-sieve plate 25 stops at the bottom of the hopper 5, the stepper motor 24 stops rotating. At this moment, the crushed non-woven fabric falls on the first sub-sieve plate 25. Under the action of the vibrator 28, small pieces of non-woven fabric are shaken off the first sub-sieve plate 25, and the second sub-sieve plate 26 moves to the bottom of the second recovery pipe 15.

[0049] The fan 16 is turned on to suck air, and the large piece of non-woven fabric on the second sub-screen plate 26 is sucked into the recovery box 13 from the second recovery pipe 15. The large piece of non-woven fabric is affected by the airflow, pumped out from the discharge pipe 17, falls into the hopper 5, and is crushed again.

[0050] When the non-woven fabric on the second sub-sieve plate 26 is sucked out, the stepper motor 24 is reversed. When the first sub-sieve plate 25 reaches below the first recovery pipe 14, the rotation of the stepper motor 24 is stopped, and the large pieces of non-woven fabric on the first sub-sieve plate 25 and the large pieces of non-woven fabric on the second sub-sieve plate 26 are pumped into the hopper 5 in the same way for re-crushing.

[0051] It should be noted that the staff can set the forward and reverse rotation time of the stepper motor 24 according to the flow rate of the non-woven fabric raw material discharged from the bottom of the hopper 5, so that the first sub-sieve plate 25 and the second sub-sieve plate 26 can be alternately moved to the bottom of the hopper 5 to screen the non-woven fabric. At the same time, cooperate with the recovery component 3 to alternately suck large pieces of non-woven fabric into the hopper 5 for re-crushing, which can ensure that the sucked non-woven fabrics are large pieces, reduce the accidental suction of small pieces of non-woven fabrics, and improve the efficiency of the entire recycling.

[0052] The device screens the crushed non-woven fabric by providing a first sub-screen plate 25 and a second sub-screen plate 26, and recycles large pieces of non-woven fabric by providing a recovery component 3, and pumps them into the hopper 5 for re-crushing, thereby solving the technical problem that in the current non-woven fabric shredding process, large pieces of non-woven fabric are still not cut into small pieces, thereby affecting the next processing process.
