[0039] Embodiment 1

[0040] Please refer to Figures 1 - 10 As shown, a precise sorting and automatic conveying system and sorting method for chemical plastic bottles include a flat feeding table 1, a spiral inclined feeding table 2 and a cleaning assembly; the cleaning assembly includes a placing rack 3;

[0041] One side of the flat feeding table 1 is fixedly connected to one side of the spiral inclined feeding table 2. The bottom of the placing rack 3 is fixedly connected to the top of the flat feeding table 1. Both sides of the placing rack 3 are fixedly connected with supporting clamping plates 4. One side of the supporting clamping plate 4 is fixedly connected with a motor base 5. The top of the motor base 5 is fixedly connected with a motor 6. The output shaft of the motor 6 is fixedly connected with an active reciprocating lead screw 7 through a coupling. The surface of the active reciprocating lead screw 7 is threadedly connected with a sliding material guiding hopper 8. The surface of the sliding material guiding hopper 8 is slidably connected to the surface of the placing rack 3. The bottom end of the sliding material guiding hopper 8 is communicated with a cleaning spray head 9. The surfaces of the flat feeding table 1 and the spiral inclined feeding table 2 are drivingly connected with a round hole conveyor belt 10. Both sides of the top of the spiral inclined feeding table 2 are fixedly connected with dryers 11;

[0042] During operation, before sorting, the chemical plastic bottles are processed first, the chemical liquid inside is cleaned and washed, and the washed chemical plastic bottles are placed in the circular hole conveyor belt 10 on the plane feeding table 1, and are transported by the circular hole conveyor belt 10. The plane feeding table 1 is connected to the spiral inclined feeding table 2 to form a complete feeding mechanism. At the same time, the spiral inclined feeding table 2 gradually spirals upward and can be used for draining and reflux. The plane feeding table 1 supports the placement rack 3, and the placement rack 3 supports the supporting card plate 4. The chemical plastic bottles are placed on the circular hole conveyor belt 10 for transportation. The motor seat 5 supports the installation of the motor 6. When the motor 6 is working, the active reciprocating screw rod 7 is driven to rotate through the output shaft. After the active reciprocating screw rod 7 rotates, it drives the sliding guide hopper 8 to slide back and forth, thereby sliding back and forth along the placement rack 3, and cooperates with the cleaning nozzle 9 to clean the chemical plastic bottles. Then, the dryer 11 dries the cleaned chemical plastic bottles, and the function of secondary cleaning of the chemical plastic bottles is realized as a whole. When conveying, the cleaning nozzle 9 is used to clean the chemical plastic bottles. The chemical plastic bottle is cleaned to remove the attached chemical liquid as much as possible, and the volatilization of the smell of the chemical liquid is also avoided. During the overall work, the chemical plastic bottle is placed on the round hole conveyor belt 10, and needs to be stuck in the round hole of the round hole conveyor belt 10. Then the round hole conveyor belt 10 transports the chemical plastic bottle. In this transportation process, the surface of the chemical plastic bottle is continuously cleaned by the cleaning nozzle 9. On the one hand, the cleaning is for secondary cleaning, and on the other hand, the liquid is used to reduce the volatilization of the residual chemical liquid smell inside the chemical plastic bottle. Water stains will be generated during the cleaning process. In order to better sort and transport, these water stains need to be processed. This processing method, first, uses the spiral inclined feeding table 2 for automatic drainage treatment, and second, uses the dryer 11 to dry the surface of the chemical plastic bottle. However, the temperature of the dryer 11 needs to be set here to avoid the chemical plastic bottle from being significantly deformed due to high temperature. This solves the problem that there are still some harmful substances after a single treatment, which may cause some unnecessary damage during the transportation process, thereby improving the efficiency of sorting and transportation.

[0043] Further, one end of the active reciprocating lead screw 7 away from the motor 6 is fixedly connected with an active pulley 12. On both sides of the placing rack 3 and on both sides of the active reciprocating lead screw 7, auxiliary reciprocating lead screws 13 are rotatably connected. One end of each auxiliary reciprocating lead screw 13 is fixedly connected with a driven pulley 14. The surface of the active pulley 12 is drivingly connected with the surface of the driven pulley 14 through a belt. A reciprocating sliding seat 15 is threadedly connected to the surface of the auxiliary reciprocating lead screw 13. The surface of the reciprocating sliding seat 15 is slidably connected to the surface of the placing rack 3. The bottom of the reciprocating sliding seat 15 is fixedly connected with a connecting support rod 16. The bottom end of the connecting support rod 16 is fixedly connected with a liquid brushing plate 17. The bottom of the liquid brushing plate 17 is attached to the surface of the circular hole conveyor belt 10. The bottom of the plane feeding table 1 is fixedly connected with a liquid storage tank 18. A liquid guide pipe 19 is communicated inside the liquid storage tank 18. The top end of the liquid guide pipe 19 is communicated with the surface of the sliding material guide hopper 8. One side of the inner wall of the liquid storage tank 18 is fixedly connected with a filtering sieve plate 20. On one side of the liquid storage tank 18 and at the top of the filtering sieve plate 20, a filtrate recovery hopper 21 is communicated. The top of the filtrate recovery hopper 21 is fixedly connected with the bottom of the plane feeding table 1. The number of the reciprocating sliding seats 15 and the connecting support rods 16 is both set to two, and the two reciprocating sliding seats 15 and the connecting support rods 16 are symmetrically arranged on both sides of the placing rack 3. The bottom of one side of one of the connecting support rods 16 is fixedly connected with a rotating clamping column 22. The surface of the rotating clamping column 22 is rotatably connected with a telescopic rod 23. One end of the telescopic rod 23 is fixedly connected with a rotating table 24. The surface of the rotating table 24 is rotatably connected with the surface of the liquid storage tank 18. The surface of the rotating table 24 is fixedly connected with a rotating shaft 25. The rotating column is arranged at the bottom of the filtering sieve plate 20. The surface of the rotating shaft 25 is rotatably connected with the surface of the liquid storage tank 18. The surface of the rotating shaft 25 is fixedly connected with a vibration cam 26.

[0044] During operation, the active reciprocating lead screw 7 and the auxiliary reciprocating lead screw 13 both rotate on the placement rack 3, and the placement rack 3 supports the active reciprocating lead screw 7 and the auxiliary reciprocating lead screw 13. When the motor 6 operates, it drives the active reciprocating lead screw 7 to rotate. Since the driven pulley 14 is fixed to one end of the active reciprocating lead screw 7, the active reciprocating lead screw 7 drives the driving pulley 12 to rotate. The driving pulley 12 and the driven pulley 14 are connected by belt drive, so that after the driving pulley 12 rotates, it can drive the driven pulley 14 to rotate through the belt. The auxiliary reciprocating lead screw 13 is fixed to the driven pulley 14, so that after the driven pulley 14 rotates, it can drive the auxiliary reciprocating lead screw 13 to rotate. The rotation of the auxiliary reciprocating lead screw 13 drives the reciprocating sliding seat 15 to reciprocate. Here, the reciprocating sliding seat 15 is slidably connected to the surface of the placement rack 3, and the placement rack 3 limits the reciprocating sliding seat 3. At the same time, the reciprocating sliding seat 3 can also slide on the placement rack 3. Since the connecting support rod 16 is fixed to the bottom of the reciprocating sliding seat 15, the connecting support rod 16 and the reciprocating sliding seat 15 form an integral body. The liquid brushing plate 17 is fixed to the connecting support rod 16. When the reciprocating sliding seat 3 slides, it will drive the connecting support rod 16 to slide. As a whole, the reciprocating sliding seat 15 can cooperate with the connecting support rod 16 to drive the liquid brushing plate 17 to slide on the round-hole conveyor belt 10. Also, since the bottom of the liquid brushing plate 17 is attached to the round-hole conveyor belt 10, the liquid brushing plate 17 can scrape the liquid on the round-hole conveyor belt 10 until the liquid brushing plate 17 brushes the liquid on the round-hole conveyor belt 10 to one side of the planar feeding table 1 and falls into the filtrate recovery hopper 21, thus completing the recovery. At the same time, rectangular sliding openings are opened on both sides of the planar feeding table 1. The liquid brushing plate 17 is composed of two rectangles, one long and one short. The long part penetrates through the rectangular sliding opening, and the short part is the part for scraping the liquid, so that the cleaned liquid can be recovered faster. In addition, a liquid storage tank 18 is provided. The liquid storage tank 18 stores liquid inside. The liquid inside the liquid storage tank 18 is transported to the sliding guide hopper 8 through the liquid guide pipe 19. A water pump is provided inside the liquid storage tank 18. The water pump is communicated with the liquid guide pipe 19. One end of the liquid guide pipe 19 penetrates outside the liquid storage tank 18, so that the end of the liquid guide pipe 19 outside the liquid storage tank 18 is inside the sliding guide hopper 8, enabling the liquid inside the liquid storage tank 18 to enter the sliding guide hopper 8. Then, the chemical plastic bottles are cleaned by the cleaning nozzles 9, which is also convenient for cleaning as a whole. A filter screen plate 20 is fixed inside the liquid storage tank 18 to filter the recovered cleaning liquid.In addition, a filtrate recovery hopper 21 is provided so that the recovered cleaning liquid can be better recovered. During the entire cleaning process, a part of the cleaning liquid will directly fall on the flat feeding table 1 and then fall onto the filtrate recovery hopper 21, while the other part enters the spiral inclined feeding table 2. Since the spiral inclined feeding table 2 is arranged to spiral upward, when the chemical plastic bottle enters the spiral inclined feeding table 2, the water stains on the surface of the chemical plastic bottle will fall on the spiral inclined feeding table 2 and then continue to slide onto the flat feeding table 1 and finally still enter the filtrate recovery hopper 21. With the cleaning, whether it is the dust in the air or the impurities on the surface of the chemical plastic bottle, they will enter the filtrate recovery hopper 21 along with the liquid. In order to handle the impurities on the filtrate recovery hopper 21, a filter sieve plate 20 filters these impurities. As the impurities continue to accumulate, it may cause the filter sieve plate 20 to become blocked. Two reciprocating sliding seats 15 are provided, symmetrically arranged on both sides of the placement rack 3, and a rotating clamping column 22 is fixedly connected to the connecting support rod 16 at the bottom of one of the reciprocating sliding seats 15. The rotating clamping column 22 is used to rotatably support the telescopic rod 23, so that after the reciprocating sliding seat 15 moves, it drives the telescopic rod 23 to expand and contract and drives the telescopic rod 23 to rotate, thereby causing the rotating turntable 24 to rotate. When the rotating turntable 24 rotates, it can drive the rotating shaft 25 to rotate. After the rotating shaft 25 rotates, it drives the vibration cam 26 to rotate, so that the vibration cam 26 can slap the filter sieve plate 20 after rotation. As the vibration cam 26 continuously slaps the filter sieve plate 20, the filter sieve plate 20 can be vibrated, and the impurities accumulated on the surface of the filter sieve plate 20 can be bounced up, which can prevent the filter sieve plate 20 from being blocked. Overall, it realizes the functions of scraping the liquid on the surface of the round hole conveyor belt 10 and vibrating the filter sieve plate 20, solves the problems that the liquid is likely to remain on the round hole conveyor belt 10 after cleaning and the cleaning impurities are not easy to clean, and improves the adaptability during cleaning.

[0045] Furthermore, the bottom of both sides of the placement rack 3 is rotatably connected with a material pressing rotating rod 27, and the bottom of both sides of the placement rack 3 is sleeved with a torsion spring 28. The top and bottom of the torsion spring 28 are respectively fixedly connected to the bottom of the material pressing rotating rod 27 and the top of the flat feeding table 1. The number of the material pressing rotating rods 27 and the torsion springs 28 is set to be multiple, and the multiple material pressing rotating rods 27 and torsion springs 28 are respectively arranged in two-by-two symmetry on both sides of the top of the flat feeding table 1.

[0046] During operation, a plurality of material-blocking rotating rods 27 are arranged at the bottom of the placement rack 3, with two in a group, arranged on both sides of the placement rack 3, and a torsion spring 28 is fixed at the bottom of the material-blocking rotating rod 27. Due to the elastic force of the torsion spring 28, the initial state of the material-blocking rotating rod 27 is set at a position maintaining a forty-five degree angle with the placement rack 3. As the round-hole conveyor belt 10 conveys the chemical plastic bottles, the material-blocking rotating rod 27 is pushed away. After continuing to convey, the chemical plastic bottles are separated from the material-blocking rotating rod 27, and the material-blocking rotating rod 27 rebounds and returns to the initial position, thereby realizing the function of limiting the chemical plastic bottles as a whole, solving the problem that the chemical plastic bottles may be easily retreated along with the cleaning liquid after being separated from the round-hole conveyor belt 10 during transportation, thereby improving the stability of the conveying process.

[0047] Furthermore, a conveying platform 29 is fixedly connected to a side of the spiral inclined feeding platform 2 away from the planar feeding platform 1 , and a feeding belt 30 is drivingly connected to the surface of the conveying platform 29 .

[0048] During operation, since the conveyor table 29 is fixed on one side of the spiral inclined feeding table 2, the cleaned and dried chemical plastic bottles enter the conveyor table 29, and the other end of the conveyor table 29 is set at the position where transportation is required, so that the feeding belt 30 on the conveyor table 29 can transport the chemical plastic bottles to the designated place.

[0049] Further, the specific steps of the precise sorting and sorting method of chemical plastic bottles are:

[0050] S1: First, process the chemical plastic bottle and clean and wash the chemical liquid inside;

[0051] S2: The cleaned chemical plastic bottles are placed in the round hole conveyor belt 10 on the flat feeding table 1 and transported by the round hole conveyor belt 10;

[0052] S3: During transportation, the chemical plastic bottle is cleaned by using the cleaning nozzle 9 to remove the attached chemical liquid as much as possible and to prevent the odor of the chemical liquid from volatilizing;

[0053] S4: After cleaning, the chemical plastic bottles continue to enter the spiral inclined feeding platform 2 along the round hole conveyor belt 10, and the chemical plastic bottles are continuously drained on the spiral inclined feeding platform 2, and the dryer 11 is used to remove as much water stains on the surface of the chemical plastic bottles as possible;

[0054] S5: The chemical plastic bottles that have been finally processed enter the conveying platform 29 and are conveyed to a designated place by a feeding belt 30 on the conveying platform 29.

[0055] The basic principles, main features and advantages of the present invention have been shown and described above. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present invention.
