[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1 to 5 As shown in this embodiment, a multi-axis PVC particle sorting device includes a vibrating screen frame 1. A base for supporting the vibrating screen frame 1 is elastically installed at the bottom of the vibrating screen frame 1. Vibrating motors and other components for sorting are fixed on the vibrating screen frame 1. The vibrating screen frame 1 includes an upper vibrating screen 111 and a lower vibrating screen 222. The upper vibrating screen 111 is fixedly installed on top of the lower vibrating screen 222. A screen mesh 2 is provided in the middle of the upper vibrating screen 111. Discharge ports are provided at the ends of both the upper vibrating screen 111 and the lower vibrating screen 222. A pusher plate 3 is slidably installed inside the upper vibrating screen 111, and the pusher plate 3 can rise and fall with the movement of the pusher plate 3. A lifting plate 4 is slidably installed inside the lower vibrating screen 222. The upper surface of the screen 4 is uniformly fixed with top posts 5. The top posts 5 can pass through the screen holes in the screen 2, and several top posts 5 are set with several screen holes in the screen 2. During the screening and sorting process, the pusher plate 3 can be intermittently controlled to push the PVC particles above the screen 2 to the feeding end of the upper vibrating screen 111. The pusher plate 3 can be intermittently raised and lowered to push the PVC particles multiple times, which can improve the screening and sorting effect of PVC particles. Efficient screening and sorting can be achieved without an excessively long vibrating screen frame 1. By controlling the lifting plate 4 to rise, the top posts 5 on the lifting plate 4 will pass through the screen holes in the screen 2, which can push the PVC particles stuck in the screen holes of the screen 2 to clean the screen holes and improve the screening and sorting effect of the screen 2 on PVC particles.

[0024] like Figures 1 to 5 As shown, side frames 6 are welded to both sides of the upper vibrating screen 111. A movable seat 7 is slidably installed between the two side frames 6. A first limiting rod 8 is symmetrically slidably installed inside the movable seat 7. The bottom ends of the two first limiting rods 8 are welded and fixed to the push plate 3. A guide rod 9 is welded and fixed between the top ends of the two first limiting rods 8. A first return spring 10 is sleeved on the outer side of the bottom end of the first limiting rod 8. When the first return spring 10 is in its normal state, the first return spring 10 pushes the first limiting rod 8 and controls the guide rod 9 to be in the middle position of the two inclined sides of the parallelogram guide groove 11. One end of the first return spring 10 is fixedly connected to the push plate 3, and the other end of the first return spring 10 is fixedly connected to the lower surface of the movable seat 7. A parallelogram guide groove 11 is opened on the inner side of the two side frames 6. The parallelogram guide groove 11 is an oblique parallelogram mechanism. The end of the guide rod 9 is slidably installed inside the parallelogram guide groove 11.

[0025] By intermittently moving the movable seat 7 left and right, the guide rod 9 is positioned inside the lower edge of the parallelogram guide groove 11. At this time, the first return spring 10 is in a stretched state, and the bottom of the pusher plate 3 is close to but not in contact with the upper surface of the screen 2. This allows the PVC particles above the screen 2 to be pushed to the feeding end of the upper vibrating screen 111. When the guide rod 9 moves to the lower corner of the parallelogram guide groove 11 near the feeding end of the PVC particles, the movement of the pusher plate 3 stops, and then the pusher plate 3 moves in the opposite direction. Simultaneously, the upward pull of the first limit rod 8 by the first return spring 10 causes the guide rod 9 to move vertically upward, moving it along the inclined side of the parallelogram guide groove 11. The guide rod 9 is then controlled to move upward along the parallelogram guide groove 11. The upper straight edge of the parallelogram guide groove 11 moves, at which time the first return spring 10 is in a compressed state. When the guide rod 9 moves to the upper corner of the parallelogram guide groove 11 near the end where the PVC particles are fed, it stops moving the pusher plate 3. Then, it drives the pusher plate 3 to move forward again. At the same time, the push of the first limit rod 8 by the first return spring 10 will drive the guide rod 9 to move downward in the vertical direction. It will drive the guide rod 9 to move downward and upward along the inclined side of the parallelogram guide groove 11. Then, it will control the guide rod 9 to move along the upper straight edge of the parallelogram guide groove 11, so as to push the PVC particles above the screen 2 to the feeding end of the upper vibrating screen 111 again. The multiple pushes of the PVC particles can improve the screening and sorting effect of the PVC particles.

[0026] like Figures 1 to 5 As shown, positioning rods 12 and screws 13 are fixedly installed on the two side frames 6 respectively and rotated through bearings. One end of the movable seat 7 is slidably connected to the positioning rods 12, and the other end of the movable seat 7 is threadedly connected to the screws 13.

[0027] By controlling the rotation of the screw 13, the moving seat 7 is driven to move horizontally along the trajectory of the positioning rod 12 through the threaded connection between the moving seat 7 and the screw 13.

[0028] like Figures 1 to 5 As shown, a driven bevel gear 14 is fixedly installed at one end of the screw 13, and a motor 15 is fixedly installed on one side of the upper vibrating screen 111 at the position corresponding to the driven bevel gear 14. A driving bevel gear 16 is fixedly installed on the output shaft of the motor 15, and the driving bevel gear 16 is meshed with the driven bevel gear 14.

[0029] By controlling the operation of the motor 15, the output shaft of the motor 15 will drive the drive bevel gear 16 to rotate, and the meshing of the drive bevel gear 16 and the driven bevel gear 14 will drive the screw 13 to rotate.

[0030] like Figures 1 to 5As shown, a rotating shaft 17 is rotatably mounted in the middle of the lower vibrating screen 222 via a bearing. A cam 18 is fixedly mounted in the middle of the rotating shaft 17. Second limiting rods 19 are symmetrically fixedly mounted inside the lower vibrating screen 222. The lifting plate 4 is slidably mounted on the outside of the four second limiting rods 19. The cam 18 is located below the lifting plate 4 and is in contact with the lower surface of the lifting plate 4. A second return spring 20 is sleeved on the outside of the second limiting rod 19. One end of the second return spring 20 is fixedly connected to the outer wall of the middle end of the second limiting rod 19, and the other end of the second return spring 20 is fixedly connected to the lower surface of the lifting plate 4.

[0031] The control drives the rotating shaft 17 to rotate. The protruding position of the cam 18 on the rotating shaft 17 will intermittently press the lower surface of the lifting plate 4, which will drive the lifting plate 4 to slide upward along the four second limit rods 19. At this time, the second return spring 20 is in the stretched state, and the top column 5 on the lifting plate 4 will pass through the screen hole in the screen 2. When the rotating shaft 17 continues to rotate, the lifting plate 4 can be driven to descend and reset by the pull of the second return spring 20.

[0032] like Figures 1 to 5 As shown, the output shaft of the motor 15 is fixedly mounted with a first pulley 21, and one end of the rotating shaft 17 is fixedly mounted with a second pulley 22. A transmission belt 23 is installed between the second pulley 22 and the first pulley 21.

[0033] When the motor 15 is running, the transmission belt 23 will synchronously drive the rotating shaft 17 to rotate through the transmission belt 23 to the second pulley 22 and the first pulley 21.

[0034] like Figures 1 to 5 As shown, the lifting plate 4 has through holes 24 equidistantly arranged in the middle. The through holes 24 are through holes.

[0035] The perforation 24 can be used to continuously drop PVC particles falling from the sieve holes of the screen 2.

[0036] This utility model provides a multi-axis PVC particle sorting device, the specific working principle of which is as follows:

[0037] In use, PVC particles are poured into one end of the upper vibrating screen 111. The vibration of the device is controlled by the operation of a vibrating motor, enabling the PVC particles to vibrate and move within the upper vibrating screen 111. The PVC particles are screened and sorted through the screen 2 on the upper vibrating screen 111. Small particles fall through the screen holes of the screen 2 into the lower vibrating screen 222. The PVC particles inside the upper vibrating screen 111 and the lower vibrating screen 222 are discharged through the discharge port at the end. The screening and sorting principle described above is the same as that of the vibrating screen frame 1 in the prior art. During the above screening and sorting process of PVC particles... The motor 15 can be intermittently controlled to operate. The output shaft of the motor 15 will drive the active bevel gear 16 to rotate. Through the meshing of the active bevel gear 16 and the driven bevel gear 14, the screw 13 will rotate. Through the threaded connection between the movable seat 7 and the screw 13, the movable seat 7 will move along the trajectory of the positioning rod 12. At this time, the guide rod 9 is inside the lower side of the parallelogram guide groove 11, and the first return spring 10 is in the stretched state. The bottom of the push plate 3 is close to but not in contact with the upper surface of the screen 2, which can push the PVC particles above the screen 2 to the feeding end of the upper vibrating screen 111. When the guide rod 9 moves close to the feeding end of the PVC particles... When the guide rod reaches the lower corner of the parallelogram guide groove 11 at one end, it stops moving the pusher plate 3. Then, by controlling the output shaft of the motor 15 to rotate in the reverse direction, the pusher plate 3 moves in the reverse direction. At the same time, the first return spring 10 pulls the first limit rod 8 upward, which drives the guide rod 9 to move upward in the vertical direction. This drives the guide rod 9 to move upward along the inclined side of the parallelogram guide groove 11. Then, the guide rod 9 moves along the upper straight side of the parallelogram guide groove 11. At this time, the first return spring 10 is in a compressed state. When the guide rod 9 moves to the upper corner of the parallelogram guide groove 11 near the PVC particle feeding end, it stops moving the pusher plate 3. The material is moved, and then the output shaft of the motor 15 is rotated forward again to drive the pusher plate 3 to move forward. At the same time, the first limit rod 8 is pushed by the first reset spring 10 to drive the guide rod 9 to move downward in the vertical direction. The guide rod 9 will move downward and upward along the inclined side of the parallelogram guide groove 11. Then, the guide rod 9 will be controlled to move along the upper straight side of the parallelogram guide groove 11, so as to push the PVC particles above the screen 2 to the feeding end of the upper vibrating screen 111 again. The multiple pushes of the PVC particles can improve the screening and sorting effect of PVC particles, and efficient screening and sorting can be achieved without the need for an excessively long vibrating screen frame 1.

[0038] When the motor 15 is running, the transmission belt 23 drives the second pulley 22 and the first pulley 21 to rotate the shaft 17. The protruding position of the cam 18 on the shaft 17 will intermittently press the lower surface of the lifting plate 4, which will drive the lifting plate 4 to slide upward along the four second limit rods 19. At this time, the second return spring 20 is in the stretched state, and the top column 5 on the lifting plate 4 will pass through the screen hole in the screen 2, which can push the PVC particles stuck in the screen hole of the screen 2 to clean the screen hole and improve the screening and sorting effect of the screen 2 on PVC particles. When the shaft 17 continues to rotate, the second return spring 20 pulls the lifting plate 4 to drive the lifting plate 4 to descend and reset.
