The old clothes dropped from the delivery bin 10 are carried by two symmetrically distributed supporting metal sheets 610, and then the supporting frame 601 is driven to vibrate by four vibration motors 603, so that the two supporting metal sheets 610 vibrate up and down, and the old clothes stacked on the surface of the supporting metal sheets 610 are shaken and loosened, so that the old clothes are evenly distributed on the surfaces of the two supporting metal sheets 610.

[0023] Four support grooves 611 are provided on the inner side of the support frame 601, and the end of the sliding support rod 609 is slidably engaged with the inner side of the support groove 611. A return spring 612 is also installed on the inner side of the support groove 611.

The guide screw 404 passes through the threaded hole and is threadedly connected to the guide screw 404. After the adjusting motor 405 is powered on and started, the position of the lifting bar 402 can be changed by driving the guide screw 404 to rotate, thereby realizing the opening or closing of the delivery port 2.

[0025] Two rotating plates 403 are provided between the fixed bar 401 and the lifting bar 402, and the ends of the rotating plates 403 contacting the fixed bar 401 and the lifting bar 402 are penetrated and plugged with rotating shafts, and the two ends of the rotating shafts are rotatably connected with the fixed bar 401 and the lifting bar 402, and the angle between the two rotating plates 403 is an obtuse angle, and the middle of the ends of the two rotating plates 403 contacting each other are provided with docking grooves 406, and a rotating connecting piece 407 is provided between the two docking grooves 406, and the two ends of the rotating connecting piece 407 are both half-circular arc surfaces, and the two ends of the rotating connecting piece 407 are penetrated and plugged with rotating pins 408, and the ends of the rotating pins 408 are rotatably plugged into the inside of the rotating plates 403. The two rotating plates 403 distributed at an obtuse angle, when the lifting bar 402 moves upward, the two rotating plates 403 are squeezed and the angle between them is reduced. At this time, the two rotating plates 403 are close to each other, so that the delivery port 2 closed by the two rotating plates 403 is opened, which is convenient for users to put in old clothes.

[0026] like Figure 3 , Figure 5 and Figure 6 As shown, a weighing structure 5 is installed on the inner side of the delivery bin 10, and the weighing structure 5 includes an adjustable electric telescopic rod 501 and a rotating support plate 502. One end of the rotating support plate 502 is rotatably connected to the inner side of the rotating groove 8, and the bottom end of the adjustable electric telescopic rod 501 is fixedly inserted into the inside of the recycling box body 1 and the overall inclination of the adjustable electric telescopic rod 501 is adjusted. A storage groove 504 is provided on the bottom surface of the rotating support plate 502, and the top end of the adjustable electric telescopic rod 501 is connected to the inner side of the storage groove 504. A square groove is provided on the surface of the rotating support plate 502, and a weighing scale 503 is inlaid on the inner side of the square groove. The electric telescopic rod 501 is adjusted to adjust the inclination angle of the rotating support plate 502 and the weighing scale 503, and the delivery bin 10 can be closed, and the used clothes delivered are carried and weighed by the rotating support plate 502 and the weighing scale 503.

[0027] A sliding rod 506 is inserted through the top of the adjustable electric telescopic rod 501, and two symmetrically distributed sliding grooves 505 are provided on the inner side of the storage groove 504. The two ends of the sliding rod 506 are respectively clamped on the inner sides of the two sliding rods 506, and the ends of the sliding rod 506 are rotatably connected to the rotating support plate 502. The connection between the adjustable electric telescopic rod 501 and the rotating support plate 502 is realized by the sliding rod 506, so that when the end of the adjustable electric telescopic rod 501 is recovered or extended, the angle of the rotating support plate 502 is changed, and the existence of the sliding rod 506 enables the end of the adjustable electric telescopic rod 501 to change its position inside the storage groove 504, so that the fixed position of the adjustable electric telescopic rod 501 does not affect the rotation of the rotating support plate 502.

[0028] Working principle: first, the power of the old clothes recycling box is turned on, and then the user scans the QR code from the square metal nameplate on the outside of the recycling box body 1 and starts the recycling program of the old clothes recycling box. After the recycling program is started, the adjustment motor 405 on the side where the user stands is powered on and started, and the adjustment motor 405 drives the guide screw 404 to rotate and makes the lifting bar 402 move upward along the axis direction of the guide screw 404. At this time, the lifting bar 402 approaches the fixed bar 401. As the lifting bar 402 moves, the two rotating plates 403 gradually approach each other until the lifting bar 402 reaches a limited position. At this time, the delivery port 2 is opened, and the user delivers the old clothes into the delivery bin 10 through the delivery port 2; After the old clothes enter the delivery bin 10, they are accumulated inside the weighing meter 503 on the surface of the rotating support plate 502. After all the old clothes are delivered, the user selects the delivery completion option in the recycling program through the mobile phone. After the option is selected, the motor 405 is adjusted to rotate in the opposite direction and drive the lifting bar 402 to reset, so that the two rotating plates 403 are reset and the delivery port 2 is closed again. After the delivery port 2 is closed, the weighing meter 503 weighs the total weight of the old clothes. After the weighing is completed, the weight data is fed back to the user's mobile phone terminal and the data storage terminal of the old clothes recycling box. The user knows the weight of the delivered old clothes through the data received by the mobile phone terminal; After weighing is completed, the end of the electric telescopic rod 501 is adjusted to pull the rotating support plate 502 downward. After the rotating support plate 502 rotates downward, a gap appears between the rotating support plate 502 and the inner wall of the delivery bin 10. As the rotating support plate 502 gradually rotates, the old clothes leave the delivery bin 10 from the bottom of the delivery bin 10 along the gap and fall on the surfaces of the two supporting metal sheets 610. After the old clothes on the surface of the rotating support plate 502 completely fall off, the electric telescopic rod 501 is adjusted to drive the rotating support plate 502 to rotate and reset. At this time, the four vibration motors 603 on the surface of the support frame 601 are started at the same time. After the vibration motor 603 is started, it drives the support frame 601 to vibrate up and down, so that the support frame 601 repeatedly impacts the shaking spring 604 up and down. At this time, the support frame 601 shakes up and down due to the vibration of the vibration motor 603 and the elastic force of the shaking spring 604, so that the old clothes piled on the surfaces of the two supporting metal sheets 610 are loosened due to the up and down shaking, and the old clothes are gradually evenly distributed on the surfaces of the two supporting metal sheets 610. After the old clothes are evenly distributed on the surfaces of the two supporting metal sheets 610, the vibration motor 603 stops running and waits for the support frame 601 to return to a stable state. Then the reeling motor 613 is powered on and starts to drive the rotating rod 606 and the reeling rod 605 to rotate, so that the reeling rod 605 is a pair of supporting metal sheets 610 that are retracted. At this time, the supporting metal sheets 610 pull the moving rod 608 and the sliding supporting rod 609, so that the sliding supporting rod 609 slides inside the supporting groove 611 and compresses the reset spring 612. As the gap between the two supporting metal sheets 610 gradually increases, the old clothes on the surfaces of the two supporting metal sheets 610 fall down and enter the inside of the storage bin 7, so that the old clothes are evenly distributed inside the storage bin 7 and piled up, making full use of the internal space of the storage bin 7 and avoiding waste of the internal space of the storage bin 7.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
