[0005] To achieve the above purpose, the utility model provides the following technical scheme: a waste plastic sorting device, including a base, a groove is opened on the upper end surface of the base, two limiting plates located on the left and right sides of the groove are fixedly connected to the upper end surface of the base, and a conveyor is installed inside the groove;

[0006] Two sorting mechanisms are arranged on the upper end surface of the base and distributed front and back. The sorting mechanism includes a mounting plate fixedly connected to the upper end surface of the base and in an L shape. A notch is penetrated and opened on the left side of the upper end surface of the mounting plate. A rotating plate is rotatably connected inside the notch. One end of the rotating plate extends above the conveyor. A cross plate is fixedly connected to the front end surface of the mounting plate, and a color sensor is installed on the lower end surface of the cross plate;

[0007] The upper end surface of the mounting plate is rotatably connected with a telescopic cylinder through a hinge seat, and the output end of the telescopic cylinder is rotatably connected with the other end of the rotating plate;

[0008] A feeding mechanism is arranged on the left side of the base, and a feeding plate is fixedly connected between the feeding mechanism and the base.

[0009] For pushing plastic bottles, as an optimization of the waste plastic sorting device of the present utility model, the feeding mechanism includes a storage bin. The left and right inner side walls of the storage bin are both fixedly connected with inclined plates. A baffle is fixedly connected inside the storage bin between the two inclined plates. A moving plate is slidably connected inside the storage bin below the baffle. Two push plates are fixedly connected to the upper end surface of the moving plate on the left and right sides of the baffle.

[0010] For driving the moving plate to reciprocate up and down, as an optimization of the waste plastic sorting device of the present utility model, the feeding mechanism further includes a support plate fixedly connected to the lower end inside the storage bin. A rotating wheel is rotatably connected to the left side wall of the support plate. A connecting rod is rotatably connected to the eccentric shaft of the rotating wheel.

[0014] For facilitating the pushing of plastic bottles, as an optimization of the waste plastic sorting device of the present utility model, both the baffle and the push plates are arranged in a right-leaning structure.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] The disordered plastic bottles are sorted out by the feeding mechanism and neatly pushed onto the conveyor. Then the conveyor conveys the plastic bottles, making the plastic bottles move towards the sorting mechanism. When the plastic bottles move to the sorting mechanism, the plastic bottles are scanned by the color sensor. Then the data scanned by the color sensor is transmitted into the control panel, and the data is processed and analyzed by the information processing unit, thereby identifying the color of the plastic bottles.

[0017] When the plastic bottle is colored, the control panel controls the telescopic cylinder corresponding to the color sensor to start. The telescopic cylinder expands and contracts rapidly, driving the rotating plate to swing. Then, the colored plastic bottle is pushed into the discharge groove through the discharge port by the swinging rotating plate, and then discharged centrally through the discharge groove. Two sorting mechanisms can sort plastic bottles of two different colors. When there are more types of plastic bottle colors, the number of sorting mechanisms can also be increased. Then, the transparent and colorless plastic bottles are conveyed to the rear end of the base through the conveyor and discharged, so as to sort plastic bottles of different colors.

[0023] Please refer to Figures 1 to 3, a waste plastic sorting device, including a base 1, a groove 2 is provided on the upper end surface of the base 1, two limiting plates 3 located on the left and right sides of the groove 2 are fixedly connected to the upper end surface of the base 1, and a conveyor 23 is installed inside the groove 2;

[0024] Two sorting mechanisms are arranged on the upper end surface of the base 1 and are distributed front and back. The sorting mechanism includes a mounting plate 4 fixedly connected to the upper end surface of the base 1 and in an L shape. A notch 5 is penetrated and opened on the left side of the upper end surface of the mounting plate 4. A rotating plate 6 is rotatably connected inside the notch 5. One end of the rotating plate 6 extends above the conveyor 23. A cross plate 7 is fixedly connected to the front end surface of the mounting plate 4, and a color sensor 8 is installed on the lower end surface of the cross plate 7;

[0025] The upper end surface of the mounting plate 4 is rotatably connected to a telescopic cylinder 9 through a hinge seat, and the output end of the telescopic cylinder 9 is rotatably connected to the other end of the rotating plate 6;

[0026] A feeding mechanism is arranged on the left side of the base 1, and a feeding plate 10 is fixedly connected between the feeding mechanism and the base 1.

[0027] In this embodiment: during use, plastic bottles with similar sizes and specifications are placed into the feeding mechanism, and then the feeding mechanism and the conveyor 23 are started. The plastic bottles are conveyed into the feeding plate 10 through the feeding mechanism, and then the plastic bottles roll onto the conveyor 23 through the feeding plate 10. The feeding mechanism can straighten the messy plastic bottles and push the plastic bottles neatly onto the conveyor 23, facilitating the plastic to enter between the two limiting plates 3, and the limiting plates 3 can limit the plastic bottles;

[0028] Then, the conveyor 23 conveys the plastic bottles, causing the plastic bottles to move towards the sorting mechanism. When the plastic bottles move to the sorting mechanism, the color sensor 8 (the color sensor 8 is a device that can convert the color information of an object into an electrical signal. Its working principle is based on the photoelectric effect, and it identifies colors by measuring the reflected or transmitted light of different colors, which is a well-known and mature existing technology) scans the plastic bottles, and then the data scanned by the color sensor 8 is transmitted into the control panel 20. The data is processed and analyzed by the information processing unit, and then the color of the plastic bottles is identified;

[0029] When the plastic bottle is colored, the control panel 20 controls the corresponding telescopic cylinder 9 of the color sensor 8 to start. The telescopic cylinder 9 rapidly expands and contracts, and the telescopic cylinder 9 drives the rotating plate 6 to swing. Then, the colored plastic bottle is pushed into the discharge groove 22 through the discharge port 21 by the swinging rotating plate 6. Two sorting mechanisms can sort plastic bottles of two different colors. When there are more types of plastic bottle colors, the number of sorting mechanisms can also be increased. Then, the transparent and colorless plastic bottles are conveyed to the rear end of the base 1 for discharge, thereby sorting plastic bottles of different colors.

The left and right inner side walls of the storage bin 11 are fixedly connected with inclined plates 12. A baffle 13 located between the two inclined plates 12 is fixedly connected inside the storage bin 11. A moving plate 14 located below the baffle 13 is slidably connected inside the storage bin 11. Two pushing plates 15 located on the left and right sides of the baffle 13 are fixedly connected to the upper end surface of the moving plate 14.

[0031] In this embodiment: The moving plate 14 moves up and down reciprocally. The moving plate 14 drives the two pushing plates 15 to move. Through the up and down reciprocating movement of the two pushing plates 15, the disordered plastic bottles can be sorted out and pushed at the same time.

[0032] As a technical optimization solution of the present utility model, the feeding mechanism further includes a support plate 16 fixedly connected to the lower end inside the storage bin 11. A rotating wheel 17 is rotatably connected to the left side wall of the support plate 16. A connecting rod 18 is rotatably connected to the eccentric shaft of the rotating wheel 17. The other end of the connecting rod 18 is rotatably connected to the lower end surface of the moving plate 14 through a hinge seat.

[0033] In this embodiment: The rotating wheel 17 rotates, and the rotating wheel 17 cooperates with the connecting rod 18 to drive the moving plate 14 to move up and down reciprocally.

[0034] As a technical optimization solution of the present utility model, a motor 19 is installed on the right side wall of the support plate 16. The output end of the motor 19 is fixedly connected to the rotating wheel 17.

[0035] In this embodiment: The motor 19 is started, and the motor 19 drives the rotating wheel 17 to rotate, providing power for the rotation of the rotating wheel 17.

[0036] As a technical optimization solution of the present utility model, a control panel 20 is installed on the front end surface of the storage bin 11. An information processing unit is installed inside the control panel 20. The control panel 20 is electrically connected to the conveyor 23, the color sensor 8, the telescopic cylinder 9, and the motor 19 respectively.

[0037] In this embodiment: The control panel 20 facilitates the control of the conveyor 23, the color sensor 8, the telescopic cylinder 9, and the motor 19. The information processing unit can process and analyze the data scanned by the color sensor 8.

[0038] As a technical optimization solution of the present utility model, two discharge ports 21 distributed front and back are penetrated through the left side wall of the left limiting plate 3. Two discharge grooves 22 respectively communicated with the two discharge ports 21 are fixedly connected to the left side wall of the left limiting plate 3.

[0039] In this embodiment: The discharge grooves 22 can centrally discharge the sorted plastic bottles.

[0040] As a technical optimization solution of the present utility model, both the baffle 13 and the push plate 15 are arranged in a right-ward inclined structure.

[0041] In this embodiment: both the baffle 13 and the push plate 15 are arranged in a right-ward inclined structure, which can make the plastic bottle roll to the right side, facilitating the pushing of the plastic bottle.

[0042] Working principle: During use, plastic bottles of similar size and specification are placed into the feeding mechanism, and then the motor 19 and the conveyor 23 are started by controlling through the control panel 20. The motor 19 drives the runner 17 to rotate, and the runner 17 cooperates with the connecting rod 18 to drive the moving plate 14 to move up and down reciprocally. The moving plate 14 drives the two push plates 15 to move. Through the up and down reciprocating movement of the two push plates 15, the plastic bottles are conveyed into the material-passing plate 10, and then the plastic bottles roll onto the conveyor 23 through the material-passing plate 10;

[0043] Then, the conveyor 23 conveys the plastic bottles, making the plastic bottles move towards the sorting mechanism. When the plastic bottles move to the sorting mechanism, the plastic bottles are scanned by the color sensor 8, and then the data scanned by the color sensor 8 is transmitted into the control panel 20. The data is processed and analyzed by the information processing unit, thereby identifying the color of the plastic bottles;

[0044] When the plastic bottle is colored, the control panel 20 controls the telescopic cylinder 9 corresponding to the color sensor 8 to start. The telescopic cylinder 9 expands and contracts rapidly, and the telescopic cylinder 9 drives the rotating plate 6 to swing. Thus, the colored plastic bottle is pushed into the discharge groove 22 through the discharge port 21 by the swinging rotating plate 6, and then is centrally discharged through the discharge groove 22. Then, the transparent and colorless plastic bottles are conveyed to the rear end of the base 1 through the conveyor 23 and discharged, thereby sorting the colors of the plastic bottles.
