[0002] PET bottles are plastic bottles made of polyethylene terephthalate and are one of the most common packaging materials in the beverage, cosmetics, and other liquid product industries. PET bottles have many advantages, such as high transparency, good heat resistance, strong cold resistance, and strong chemical corrosion resistance. Therefore, they are widely used in beverage bottles, water bottles, oil bottles, sauce bottles, shampoo bottles, etc. At the same time, because PET bottles are easy to recycle and reuse and have environmental protection advantages, they are also widely used in some countries.

[0024] The transfer platform 5 includes a support frame 9. A plurality of rollers 10 are evenly and rotatably connected to the top of the support frame 9. A conveyor belt 11 is provided on the outer surface of the rollers 10. The plurality of rollers 10 are connected by a first pulley set 12. One end of one of the rollers 10 is connected to the output end of the first motor 8.

[0025] The transmission device 4 includes a second motor 13. The output end of the second motor 13 is coaxially and fixedly connected to a second pulley set 14. The second pulley set 14 is composed of two pulleys and a transmission belt. The center position of the outer surface of one of the pulleys is fixedly connected to one end of the first transmission shaft 15. The other end of the first transmission shaft 15 is rotatably connected to the inner wall of the discharge box 2. The center position of the outer surface of the other pulley is fixedly connected to one end of the second transmission shaft 25. The other end of the second transmission shaft 25 is rotatably connected to the inner wall of the miscellaneous material box 3.

[0026] A plurality of bushings 16 are evenly sleeved on the outer surface of the first transmission shaft 15. A plurality of swing rods 17 are evenly fixedly connected to the outer surface of the bushings 16. An arc is provided at the top of the swing rod 17.

[0027] Eccentric wheels 24 are respectively fixedly connected to both ends of the second transmission shaft 25. An arc-shaped plate 21 that can move up and down is slidably connected to the bottom end of the inner wall of the discharge box 2. Leakage holes 22 are evenly provided on the upper surface of the arc-shaped plate 21. Arc-shaped blocks 23 that contact the eccentric wheels 24 are respectively fixedly connected to the bottom parts on both sides of the arc-shaped plate 21.

[0028] Limit grooves 18 are respectively provided on the inner walls of both sides of the discharge box 2. The arc-shaped plate 21 is slidably connected to the inner walls of the limit grooves 18 through sliders fixedly connected to both sides. Support plates 20 are fixedly connected to the inner walls of both sides of the discharge box 2. Springs 19 are respectively fixedly connected to the bottom surfaces of the two support plates 20. The bottom surfaces of the springs 19 are fixedly connected to both sides of the upper surface of the arc-shaped plate 21.

[0029] The working principle of this device is as follows: First, pour the PET bottles to be sorted into the feeding box 1. Then, turn on the first motor 8 and the second motor 13 respectively. When the second motor 13 works, it drives the first transmission shaft 15 and the second transmission shaft 25 through the second pulley set 14. When the first transmission shaft 15 rotates, it swings the PET bottles out of the feeding box 2 through the swing rod 17. The conveying platform 5 is placed below the discharge opening opened in the discharge box 2 to receive the swung-out PET bottles. The conveying platform 5 drives the roller 10 and the conveyor 11 through the first motor 8 to realize the conveyance of the PET bottles. Specifically, during use, the sorting worker can stand on both sides of the conveying platform 5 for sorting. During the rotation of the second transmission shaft 25, the second transmission shaft drives the arc block 23 to move up and down through the eccentric wheel 24. During the up and down movement of the arc block 23, it drives the arc plate 21 to move up and down. When the arc plate 21 moves up and down, it compresses the spring 19. The elastic force generated by the elastic deformation of the spring 19 cooperates with the eccentric wheel 24 to achieve the purpose of quickly resetting the arc plate 21. Therefore, when the arc plate 21 moves up and down, the generated vibration causes the caps or other metal impurities doped in the PET bottles to leak into the miscellaneous material box 3 through the leakage holes 22, so as to achieve the purpose of collecting the impurities.

[0030] The cooperation of the discharging mechanism 6 and the vibrating sieve mechanism 7 can quickly preliminarily screen the impurities doped in the raw material bottles, improving the purity of the materials produced during the subsequent crushing of PET bottles.

[0031] This device is simple to operate, convenient to use, ingenious in structure, novel in concept, strong in practicability, wide in application range, and conducive to popularization.

[0032] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
