[0027] In one embodiment of the present invention, such as Figures 1-4 As shown, a containerized plastic bottle sorting station is provided for outdoor plastic bottle recycling. The containerized plastic bottle sorting station includes a sorting container 10 and a storage container 20.

[0028] The sorting container 10 includes at least two first containers 11; each first container 11 is spliced ​​together and interconnected to form a first space; the first space is provided with a first conveying device 12, a bottle sorting device 13 and a bottle blowing device 14. The first conveying device 12 is used to convey plastic bottles. The first conveying device 12 has an input end and an output end. The plastic bottles enter from the input end of the first conveying device 12 and leave from the output end of the first conveying device 12. The bottle sorting device 13 sprays high-pressure gas onto the plastic bottles falling from the output end of the first conveying device 12, causing the plastic bottles to fall into the bottle blowing device 14 along a parabolic path.

[0029] The storage container 20 includes at least two second containers 25; the second containers 25 are spliced ​​together and interconnected to form a second space; the second space is provided with a storage bin 21 for storing plastic bottles and a bottle packing device 22, the upper end of the storage bin 21 is connected to the first end of the first pipe 18, and the second end of the first pipe 18 is connected to the air outlet of the bottle blowing device 14 for conveying plastic bottles.

[0030] In this embodiment of the invention, multiple first containers 11 are spliced ​​together to form a sorting container 10 for plastic bottle sorting, and multiple second containers 25 are spliced ​​together to form a storage container 20 for plastic bottle storage. The first containers 11 and the second containers 25 work together to form a containerized plastic bottle sorting station, which is fast to set up, has a high reuse rate, low cost, and can complete plastic bottle sorting directly outdoors, changing the traditional plastic bottle sorting method.

[0031] In another embodiment of the present invention, two first containers 11 are provided, one of which is located above the other; the lower first container 11 has an opening at its front end. The first conveying device 12 includes a lifting conveying mechanism 120 and a translating conveying mechanism 121; the translating conveying mechanism 121 is located in the upper first container 11, and a visual inspection mechanism 122 is provided on the upper side of the translating conveying mechanism 121. The visual inspection mechanism 122 is electrically connected to the bottle sorting device 13. The first end of the lifting conveying mechanism 120 is located at the front end of the translating conveying mechanism 121, and the second end of the lifting conveying mechanism 120 is inclined downward and passes through the opening of the lower first container 11. Different types of plastic bottles are placed at the second end of the lifting conveyor 120 (i.e., the input end of the first conveyor 12). The lifting conveyor 120 conveys the plastic bottles at its second end toward its first end. The plastic bottles fall from the first end of the lifting conveyor 120 onto the translation conveyor 121. The translation conveyor 121 conveys the plastic bottles from its front end to its rear end. The vision inspection mechanism 122 identifies the plastic bottles placed on the translation conveyor 121. If the required plastic bottle is identified, the vision inspection mechanism 122 transmits the identified category information to the bottle sorting device. In step 13, when a plastic bottle falls from the rear end of the translational conveyor 121 (i.e., the output end of the first conveying device 12), the bottle sorting device 13 sprays high-pressure gas according to the category information sent by the vision inspection mechanism 122 to blow the plastic bottle up, causing it to fall along a parabolic path into the bottle blowing device 14. The bottle blowing device 14 then blows the plastic bottle into the first pipe 18, and after passing through the first pipe 18, the plastic bottle falls into the storage bin 21. If the required plastic bottle is not identified, the bottle blowing device 14 does not work when the plastic bottle falls from the rear end of the translational conveyor 121. It should be understood that the structure and working principle of the vision inspection mechanism 122 are well known to those skilled in the art, and therefore will not be described in detail.

[0032] In another embodiment of the present invention, a second conveying device 15 is provided in the lower first container 11. The second conveying device 15 is located below the translation conveying mechanism 121 to catch plastic bottles (plastic bottles not identified by the visual inspection mechanism 122) falling from the rear end of the translation conveying mechanism 121. The rear end of the second conveying device 15 is located below the rear end of the translation conveying mechanism 121. The rear end of the second conveying device 15 catches the plastic bottles falling from the rear end of the translation conveying mechanism 121. The second conveying device 15 continues to convey the falling plastic bottles and conveys the plastic bottles from their rear end to their front end.

[0033] In another embodiment of the present invention, the second container 25 is provided with a secondary sorting device 16 and a secondary blowing device 17. The secondary sorting device 16 is located at the front end of the second conveying device 15 and is used to transport plastic bottles on the second conveying device 15 to the secondary blowing device 17. The blowing end of the secondary blowing device 17 is connected to a second pipe 19. The storage bin 21 has a first cavity 23 and a second cavity 24. The first cavity 23 is connected to the first pipe 18, and the second cavity 24 is connected to the second pipe 19. The secondary sorting device 16 sprays high-pressure gas onto the plastic bottles falling from the second conveying device 15, causing the plastic bottles to fall along a parabolic path into the secondary blowing device 17. The bottle blowing device 14 then blows the plastic bottles into the second pipe 19, and the plastic bottles fall into the storage bin 21 after passing through the second pipe 19.

[0034] In another embodiment of the present invention, the second container 25 is provided with a waste material conveying device 30. The front end of the waste material conveying device 30 is located below the front end of the second conveying device 15 to catch plastic bottles falling from the second conveying device 15. The rear end of the waste material conveying device 30 extends out of the rear end of the second container 25 to convey the remaining plastic bottles to the outside of the distribution container.

[0035] In another embodiment of the present invention, the lower end of the first cavity 23 and the lower end of the second cavity 24 are both provided with bottle outlets, and a switch for controlling the opening or closing of the bottle outlet is provided at the bottle outlet.

[0036] In another embodiment of the present invention, the bottle packaging device 22 includes a first screw discharge mechanism 220 and a second screw discharge mechanism 221; the first screw discharge mechanism 220 is disposed at the bottle outlet of the first cavity 23 to output the plastic bottle placed in the first cavity 23, and the second screw discharge mechanism 221 is disposed at the bottle outlet of the second cavity 24 to output the plastic bottle placed in the second cavity 24.

[0037] In another embodiment of the present invention, the first screw discharge mechanism 220 and the second screw discharge mechanism 221 both include a trough 222, a screw 223 and a discharge motor; the upper end of the trough 222 is provided with an inlet 224 for plastic bottles to pass through, and the lower end of the trough 222 is provided with an outlet 225. A switch is provided at the outlet 225 to control the outlet 225 to open or close. The screw 223 is rotatably connected in the trough 222, and the discharge motor is fixedly connected to the outside of the trough 222. The output shaft of the discharge motor is drivenly connected to the screw 223 and is used to drive the screw 223 to rotate. The rotation of the screw 223 conveys the plastic bottles placed in the trough 222 to the outlet 225. Plastic bottles in the first chamber 23 fall into the tank 222 through the inlet 224. The discharge motor drives the screw 223 to rotate, and during the rotation of the screw 223, the plastic bottles in the tank 222 are sequentially conveyed to the discharge port 225. After passing through the discharge port 225, the plastic bottles in the tank 222 fall out of the tank 222. Specifically, a switch can be provided at the discharge port 225 to control the opening or closing of the discharge port 225.

[0038] In another embodiment of the present invention, the bottle packaging device 22 further includes a switching discharge mechanism; the switching discharge mechanism includes a discharge cylinder, a baffle, a cylinder and an annular positioning frame; the discharge cylinder is disposed on the lower side of the annular positioning frame, the annular positioning frame is disposed on the lower side of the first screw discharge mechanism 220 and the second screw discharge mechanism 221, and the baffle is slidably connected to the annular positioning frame; the cylinder is fixedly connected to the annular positioning frame, and the piston rod of the cylinder is connected to the baffle to push the baffle to slide between a front position and a rear position to block the discharge port 225 of the first screw discharge mechanism 220 or the discharge port 225 of the second screw discharge mechanism 221. When the baffle is in the front position, it blocks the discharge port 225 of the first discharge mechanism, and the discharge port 225 of the second discharge mechanism is opened, allowing the plastic bottles inside the second discharge mechanism to fall into the discharge cylinder. When the baffle is in the rear position, it blocks the discharge port 225 of the second discharge mechanism, and the discharge port 225 of the first discharge mechanism is opened, allowing the plastic bottles inside the first discharge mechanism to fall into the discharge cylinder.

[0039] In another embodiment of the present invention, a feeding pipe is provided on the side of the discharge cylinder, and the first end of the feeding pipe is connected to the middle of the discharge cylinder; a manual feeding port is provided on the outer side of the second container 25, and the manual feeding port is connected to the second end of the feeding pipe. Plastic bottles are placed into the feeding pipe through the manual feeding port to achieve manual feeding.

[0040] In another embodiment of the present invention, the bottle sorting device 13 includes a housing, a blower mechanism, a first storage pipe, and a second storage pipe. The housing is fixedly disposed on the rear side of the first conveying device 12, and the middle part of the housing is hollowed out. The blower mechanism, the first storage pipe, and the second storage pipe are all disposed in the middle part of the housing. The blower mechanism, the first storage pipe, and the second storage pipe are arranged sequentially in a direction away from the first conveying device 12. The blower mechanism generates high-pressure gas to blow plastic bottles that fall from the first conveying device 12 into the second storage pipe. The second storage pipe is connected to the bottle blowing device 14. Plastic bottles that are not sprayed by high-pressure gas fall into the first storage pipe. The first storage pipe transports the plastic bottles to the second conveying device 15.

[0041] In another embodiment of the present invention, solar panels are laid on the outer surfaces of the first container 11 and the second container 25. The solar panels are electrically connected to a storage battery, which is located inside the first container 11. The storage battery is electrically connected to the first conveying device 12, the bottle sorting device 13, the bottle blowing device 14, and the bottle packaging device 22, respectively, thereby providing power to the bottle sorting device 13, the bottle blowing device 14, and the bottle packaging device 22. The bottle blowing device 14 is a prior art device, which includes a housing and a blower. The middle part of the housing is located in the cavity, and the upper end of the housing has an inlet communicating with the cavity for plastic bottles to pass through. The side end of the housing has an outlet communicating with the cavity. The air outlet of the blower is placed in the cavity and faces the outlet. The high-speed airflow generated by the air outlet of the blower blows the plastic bottles in the cavity, causing the plastic bottles to pass through the outlet and enter the first pipe 18. The plastic bottles are transported along the first pipe 18 under the drive of the high-speed airflow and finally enter the storage bin 21.

[0042] In this embodiment, compared to traditional sorting devices that cannot adapt to high-speed sorting, have low production efficiency, and create bottlenecks in production volume and efficiency, and whose excessive clamping and driving functions lead to cost waste and are detrimental to enterprise development, the classification container 10 provided in this embodiment sorts and collects the goods through two methods after category screening: normal conveying and high-speed airflow blowing. On the one hand, it abandons the traditional expensive clamping and driving equipment, reducing production costs. On the other hand, the air blowing unit is easy to control, easy to operate and adjust, can cope with high-speed sorting conditions, has high practicality, and is beneficial to enterprise development.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
