Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] To make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0022] Refer to Figures 1-4, the present invention provides a degradable plastic particle feeding device, which includes a box body 1. A screening cylinder 2 is rotatably connected inside the box body 1. The screening cylinder 2 is inclined. An adjusting assembly for adjusting the screening size is arranged on the circumferential side of the screening cylinder 2. A driving assembly for driving the screening cylinder 2 to rotate is installed on the side wall of the box body 1. A collecting hopper 3 is fixedly connected inside the box body 1. The collecting hopper 3 is located below the screening cylinder 2. A quantitative feeding assembly is slidably arranged inside the box body 1. The quantitative feeding assembly is correspondingly arranged with the discharging end of the collecting hopper 3. A moving assembly for driving the quantitative feeding assembly to reciprocate is arranged inside the box body 1. A transmission assembly is arranged between the moving assembly and the driving assembly. A collecting box 4 is arranged at the bottom of the box body 1. A collecting port 5 is correspondingly opened on the side wall of the box body 1 and the collecting box 4. The driving assembly drives the screening cylinder 2 to rotate, so as to screen the plastic particles passing through the screening cylinder 2, so that the plastic particles that do not meet the standard size move downward along the inclined screening cylinder 2, and the plastic particles that meet the standard size fall from the screening holes 33 on the circumferential side of the screening cylinder 2 into the collecting hopper 3 for collection; at the same time, the driving assembly drives the moving assembly to move through the transmission assembly, thereby driving the quantitative feeding assembly, so that the quantitative feeding assembly continuously transports the plastic particles in the collecting hopper 3 to the collecting box 4 for collection, thereby realizing quantitative transportation. The structure of the present invention is simple and the operation is convenient. It can screen plastic particles and can transport them quantitatively.

[0023] In a further optimized solution, the driving assembly includes a driving motor 6 fixedly connected to the side wall of the box body 1. The output shaft of the driving motor 6 is fixedly connected with a driving gear 7. A mating gear ring 8 meshing with the driving gear 7 is fixedly connected to the circumferential side of one end of the screening cylinder 2 located outside the box body 1. The axis of the output shaft of the driving motor 6 is parallel to the axis of the screening cylinder 2. The driving motor 6 drives the driving gear 7 to rotate, and then drives the screening cylinder 2 to rotate through the mating gear ring 8, so as to screen the plastic particles passing through the screening cylinder 2.

[0024] For a further optimized solution, the quantitative feeding component includes a moving plate 9 located inside the box body 1 and slidably connected to the inner wall of the box body 1. The moving plate 9 is located below the collecting hopper 3 and is in contact with the collecting hopper 3. A through hole 10 is formed in the moving plate 9, and a quantitative cylinder 11 is fixedly connected to the bottom surface of the moving plate 9. The inner diameters of the through hole 10 and the quantitative cylinder 11 are both adapted to the inner diameter of the discharge end of the collecting hopper 3; a baffle 12 is rotatably connected to the bottom surface of the quantitative cylinder 11, and a push plate 13 is fixedly connected to the inner wall of the box body 1. The push plate 13 is arranged corresponding to the baffle 12, and the top surface of the push plate 13 is in contact with the bottom surface of the baffle 12 in the horizontal state. An upward inclined surface is formed at one end of the push plate 13 close to the quantitative cylinder 11. The moving component drives the moving plate 9 to perform a reciprocating linear motion. When the through hole 10 coincides with the collecting hopper 3, the plastic particles in the collecting hopper 3 move through the through hole 10 into the quantitative cylinder 11 and fill the quantitative cylinder 11. At this time, the baffle 12 is in the horizontal state under the action of the push plate 13, and the plastic particles cannot fall. When the moving plate 9 drives the quantitative cylinder 11 to move towards the middle of the box body 1, the baffle 12 is no longer limited by the push plate 13, and the baffle 12 opens under the action of gravity, and the plastic particles in the quantitative cylinder 11 fall and move into the collecting box 4 to complete the collection.

[0025] For a further optimized solution, the moving component includes a mounting frame 14 located at the bottom of the collecting hopper 3 and fixedly connected to the inner wall of the box body 1. A turntable 15 is rotatably connected to the bottom surface of the mounting frame 14. Connecting columns are respectively fixedly connected to the circumferential side of the bottom surface of the turntable 15 and the top surface of the moving plate 9, and a connecting plate 16 is rotatably connected between the two connecting columns. The connecting plate 16 is horizontally arranged. The driving component drives the turntable 15 to rotate through the transmission component, and the turntable 15 drives the moving plate 9 to reciprocate during the rotation process through the connecting plate 16.

[0026] Further optimization solution: The transmission assembly includes a mounting block 17 fixedly connected to the bottom wall of the collection hopper 3. A first transmission shaft 18 is rotatably connected between the mounting block 17 and the inner wall of the box body 1. A second transmission shaft 19 is rotatably connected between the bottom wall of the collection hopper 3 and the inner wall of the box body 1. Both the first transmission shaft 18 and the second transmission shaft 19 are horizontally arranged. Conical blocks 20 are fixedly connected to the first transmission shaft 18 and the second transmission shaft 19 respectively. The two conical blocks 20 are symmetrically arranged. The bottom side generatrix of the conical block 20 on the first transmission shaft 18 is parallel to the top side generatrix of the conical block 20 on the second transmission shaft 19. A first bevel gear 21 is fixedly connected to the second transmission shaft 19. A second bevel gear 22 is rotatably arranged on the mounting frame 14. The first bevel gear 21 meshes with the second bevel gear 22. The second bevel gear 22 is coaxially and fixedly connected to the turntable 15. A transmission wheel 23 is rotatably arranged between the two conical blocks 20. One end of the first transmission shaft 18 penetrates through the side wall of the box body 1 and is located outside the box body 1. Third bevel gears 24 are fixedly connected to the end of the first transmission shaft 18 located outside the box body 1 and the output shaft of the drive motor 6 respectively. The two third bevel gears 24 mesh with each other. The drive motor 6 drives the two third bevel gears 24 to rotate, thereby driving the first transmission shaft 18 to rotate. The first transmission shaft 18 drives the conical block 20 to rotate. The conical block 20 drives the other conical block 20 to rotate through the transmission wheel 23, thereby driving the second transmission shaft 19 to rotate. Then, the turntable 15 is driven to rotate through the cooperation of the first bevel gear 21 and the second bevel gear 22, realizing the transmission.

[0027] Further optimization solution: A control rod 25 is arranged between the inner wall of the box body 1 and the mounting block 17. The control rod 25 is parallel to the bottom side generatrix of the conical block 20 on the first transmission shaft 18. The mounting block 17 and the control rod 25 are correspondingly provided with receiving grooves. One end of the control rod 25 is located in the receiving groove. Threads are provided on the circumferential side of the other end of the control rod 25. The end of the control rod 25 provided with threads penetrates through the side wall of the box body 1 and is in threaded cooperation with the side wall of the box body 1. The control rod 25 penetrates through the transmission wheel 23 and is in rotational cooperation with the transmission wheel 23. Strip-shaped grooves for increasing friction are respectively provided on the circumferential side of the transmission wheel 23 and the circumferential side of the conical block 20. A control assembly for controlling the rotation of the control rod 25 is fixedly connected to the outer wall of the box body 1. The control assembly drives the control rod 25 to rotate. Since the control rod 25 is in threaded cooperation with the inner wall of the box body, an axial displacement occurs, thereby driving the transmission wheel 23 to move, adjusting the position of the transmission wheel 23 on the conical block 20, thereby affecting the transmission ratio and adjusting the feeding speed.

[0028] For a further optimized solution, the control component includes an installation cylinder 26 fixedly connected to the outer wall of the box body 1. A regulating knob 27 is rotatably connected inside the installation cylinder 26. The control rod 25 passes through the regulating knob 27 and is slidably engaged with the regulating knob 27 along its axial direction. A cushion block 28 is fixedly connected to the outer wall of the box body 1. A moving block 29 is slidably connected to the cushion block 28. A limiting pin 30 is fixedly connected to the side of the moving block 29 close to the installation cylinder 26. Limiting holes are correspondingly formed in the side walls of the installation cylinder 26 and the regulating knob 27. The limiting pin 30 is located in the limiting hole. A compression spring 31 is fixedly connected between the side of the moving block 29 away from the installation cylinder 26 and the cushion block 28. The regulating knob 27 is limited by inserting the limiting pin 30 into the limiting hole to prevent the control rod 25 from rotating with the transmission wheel 23. When the control rod needs to be rotated, the moving block 29 is pushed downward to make the limiting pin 30 no longer limit the regulating knob 27, and then the regulating knob 27 is rotated. The regulating knob 27 drives the control rod to rotate.

[0029] For a further optimized solution, the adjustment component includes an adjustment cylinder 32 located outside the screening cylinder 2. The adjustment cylinder 32 is slidably engaged with the screening cylinder 2 along its axial direction. Screening holes 33 are correspondingly formed on the circumferential side of the screening cylinder 2 and the circumferential side of the adjustment cylinder 32. An installation ring 34 is fixedly connected to the circumferential side at the low end of the screening cylinder 2. A plurality of threaded rods 35 are rotatably connected to the side of the installation ring 34 close to the adjustment cylinder 32. A plurality of threaded holes 36 are correspondingly formed in the end face of the adjustment cylinder 32 for the threaded rods 35. The threaded rods 35 are located in the threaded holes 36 and are threadedly connected to the adjustment cylinder 32 through the threaded holes 36. A driven gear 37 is fixedly connected to each threaded rod 35. A rotating cylinder 38 is rotatably sleeved outside the installation ring 34. A control gear ring 39 is fixedly connected to the inner wall of the rotating cylinder 38. The control gear ring 39 meshes with a plurality of driven gears 37. A plurality of bolts 40 are threadedly connected to the circumferential side of the rotating cylinder 38. The bolts 40 pass through the rotation and abut against the installation ring 34. The rotating cylinder 38 can be fixed by abutting the bolts 40 against the installation ring 34 to prevent relative rotation with the screening cylinder 2 during the screening process. By driving the control gear ring 39 to rotate through the rotating cylinder 38, all the driven gears 37 can be driven to rotate, thereby driving all the threaded rods 35 to rotate. The threaded rods 35 perform axial movement in the threaded holes 36, thereby driving the adjustment cylinder 32 to move, so that the overlapping area between the screening holes 33 on the adjustment cylinder 32 and the screening holes 33 on the screening cylinder 2 changes, thereby adjusting the screening size.

[0030] For a further optimized solution, a diversion plate 41 is fixedly connected to the inner wall of the box body 1. The diversion plate 41 is correspondingly arranged above the collection box 4. It is convenient for the plastic particles to move into the collection box 4.

[0031] For a further optimized solution, a protective cover is fixedly connected to the outside of the box body 1. The screening cylinder 2 penetrates through the protective cover. The driving gear 7 and the third bevel gear 24 are both located inside the protective cover.

[0032] Working process of the present invention: During use, degradable plastic particles are conveyed to the higher end of the screening cylinder 2 through a conveyor belt or a feeding device. The driving motor 6 is started, and the driving motor 6 drives the driving gear 7 to rotate. Then, through the cooperation with the gear ring 8, the screening cylinder 2 is driven to rotate, so as to screen the plastic particles. During the screening process, when it is necessary to adjust the screening size, only the rotating cylinder 38 needs to be rotated. During the rotation of the rotating cylinder 38, all driven gears 37 are driven to rotate through the control gear ring 39, and then all threaded rods 35 are driven to rotate, so that the threaded rods 35 move axially in the threaded holes 36, thereby driving the adjusting cylinder 32 to rotate, and changing the overlapping size of the screening holes 33 on the adjusting cylinder 32 and the screening holes 33 on the screening cylinder 2, so as to change the screening size.

[0033] The screened plastic particles are collected by the collecting hopper 3 and gathered in the collecting hopper 3. While the driving motor 6 is rotating, two third bevel gears 24 are driven to rotate through the output shaft, and then the conical block 20 on the first transmission shaft 18 is driven to rotate. Then, through the transmission of the transmission wheel 23, another conical block 20 is driven to rotate, and then the second transmission shaft 19 is driven to rotate. The second transmission shaft 19 drives the turntable 15 to rotate through the cooperation of the first bevel gear 21 and the second bevel gear 22. During the rotation of the turntable 15, the connecting plate 16 is driven to move, and then the moving plate 9 is driven to perform a reciprocating motion. During the reciprocating motion of the moving plate 9, when the through hole 10 on the moving plate 9 coincides with the bottom of the collecting hopper 3, the plastic particles in the collecting hopper moves into the metering cylinder 11. At this time, the baffle 12 is in a horizontal state under the action of the push plate 13, so that the plastic particles can only be in the metering cylinder 11. Then, the moving plate 9 drives the metering cylinder 11 to move. After the baffle 12 loses the limit of the push plate 13, it rotates under the action of gravity and moves to a vertical state. The material particles in the metering cylinder 11 move into the collecting box 4 for collection. Since the size of the metering cylinder 11 is fixed, the plastic particles that can be contained are easy to be stable within a certain range, so as to realize quantitative conveying.

[0034] When it is necessary to adjust the conveying speed, the moving block 29 is toggled downward. The moving block 29 drives the limit pin 30 to move, so that it no longer limits the adjusting knob 27. Then, the adjusting knob 27 is rotated. The adjusting knob 27 drives the control rod 25 to rotate. Since the control rod 25 is in threaded cooperation with the box body 1, the transmission wheel 23 is driven to shift. After the position of the transmission wheel 23 changes, due to the change in the position of the conical block 20 where it is located, the transmission ratio is affected, so as to adjust the transmission ratio between the first transmission shaft 18 and the second transmission shaft 19, and then adjust the movement frequency of the moving plate 9 to adjust the conveying speed.
