[0013] As a further solution of the utility model: a slope conveyor belt is arranged at one end of the identification device away from the feed box.

[0014] The beneficial effects of the utility model are:

[0015] 1. The utility model sets a lever, a first magnetic block and a second magnetic block. When the PET bottle passes the detection and is transmitted to the front of the corresponding feed box, the lever is controlled to start rotating, and the PET bottle of the specified color is quickly moved toward the feed port. When the PET bottle is about to reach the feed port, the first magnetic block and the second magnetic block attract each other, so that the second rod body accelerates to move toward the feed port, thereby better pushing the bottle into the feed box.

[0016] 2. The utility model provides a retaining tube, which can prevent the bottle from rolling to the other side of the lever before reaching the feed port when the lever moves the bottle; in addition, the retaining tube is detachably mounted on the upper end of the first rod body, and can be disassembled according to the stacking situation of the PET bottles, thereby controlling the distribution density of the PET bottles and enabling the lever to move effectively.

[0017] 3. The utility model arranges a rotating push plate. When the PET bottles are cleaned and soaked in the cleaning room, the motor starts to operate, drives the rotating push plate to rotate, and pushes the PET bottles to make them fully cleaned; after cleaning, the water pump pumps the water in the cleaning room into the water pumping tank; the dryer starts to work to dry the PET bottles. During this period, the rotating push plate keeps pushing the bottles, so that the bottles are not only fully cleaned, but also the water can be fully drained. The final push makes the bottles fully dried.

[0018] 4. The utility model sets a baffle door. When the PET bottles are dried, the electric telescopic cylinder starts to work and pulls the baffle door upward, so that the PET bottles enter the conveyor belt under the push of the rotating push plate and start to be conveyed.

[0019] 5. The utility model sets up a recognition device. When the main body of the sorting device is in operation, the image recognition module collects the image of the PET bottle, analyzes the characteristics of the PET bottle based on the image analysis module, and transmits the information to the control module; the image recognition module can adopt a common image recognition device on the market to identify information characteristics such as color and size of the PET bottle. The control module controls the motor of the corresponding lever to work according to the identified characteristics, thereby driving the lever to move; the image recognition module and the control module belong to the existing technology, so they are not described in detail here.

[0020] 6. The utility model sets a slope conveyor belt. Before the PET bottles enter the identification device, they have to pass through a slope conveyor belt. When the PET bottles stacked on the upper part reach a certain height, they will return to the original point due to unstable factors and be transported again. This not only controls the number of PET bottles detected, but also prevents them from stacking, creating conditions for subsequent detection and the movement of the lever.

DETAILED DESCRIPTION

[0025] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] Example 1

[0028] A PET bottle sorting device, such as Figure 1-3 As shown, it includes: a sorting device body 18, one end of which is provided with a feed box 11; a feed port is provided on one side of the feed box 11, and a lever 9 is rotatably installed on the side of the feed box 11 with the feed port; the lever 9 includes a first rod body 14, one end of which is hinged to one side of the feed box 11, and the other end is connected to a clockwork spring 15, and one end of the first rod body 14 is connected to a second rod body 17 through the clockwork spring 15; a second magnetic block 16 is installed on the end of the second rod body 17 away from the clockwork spring 15; a first magnetic block 10 is installed on one side of the feed box 11.

[0029] By setting the lever 9, the first magnetic block 10 and the second magnetic block 16, when the PET bottle passes the detection and is transmitted to the corresponding feed box 11, the lever 9 is controlled to start rotating, and the PET bottle of the specified color is quickly moved toward the feed port. When it is about to reach the feed port, the first magnetic block 10 and the second magnetic block 16 attract each other, so that the second rod body 17 accelerates to move toward the feed port, thereby better pushing the bottle into the feed box 11.

[0030] To prevent PET bottles from stacking, such as Figure 3 As shown, circular slots are formed at equal intervals on the upper end of the first rod body 14; and a retaining tube 13 is detachably mounted on the circular slot.

[0031] By providing the blocking tube 13, when the lever 9 moves the bottle, the blocking tube 13 can prevent the bottle from rolling to the other side of the lever 9 before reaching the feed port; in addition, the blocking tube 13 is detachably installed on the upper end of the first rod body 14, and can be disassembled according to the stacking situation of the PET bottles to control the distribution density of the PET bottles, so that the lever 9 can be effectively moved.

[0032] In order to remove the residue on the surface of PET bottles, such as Figure 1, 2, a conveyor belt is installed at one end of the main body 18 of the sorting device, and a cleaning room 3 is fixed at one end of the conveyor belt; a rotating push plate 1 is rotatably installed inside the cleaning room 3; a motor 5 is installed on the outer wall of one side of the cleaning room 3, and the output end of the motor 5 is connected to the shaft of the rotating push plate 1. A dryer 12 is arranged at the upper end of the cleaning room 3; a water pumping box 4 is installed at one side of the cleaning room 3, a water pump is installed in the water pumping box 4, and a water pumping pipe is connected to the water pump and the cleaning room 3.

[0033] By setting the rotating push plate 1, when the PET bottles are washed and immersed in the washing room 3, the motor 5 starts to operate, drives the rotating push plate 1 to rotate, and pushes the PET bottles to make them fully washed; after washing, the water pump pumps the water in the washing room 3 into the water pumping tank 4; the dryer 12 starts to work to dry the PET bottles. During this period, the rotating push plate 1 keeps pushing the bottles, so that the bottles are not only fully washed, but also the water can be fully drained, and the final push makes the bottles fully dried.

[0034] In order to allow PET bottles to enter the conveyor belt, such as Figure 1 As shown in FIG2 , a baffle door 6 is movably installed on one side of the cleaning room 3 close to the conveyor belt; an electric telescopic cylinder 2 is provided on one side of the cleaning room 3 where the motor 5 is installed, and the output end of the electric telescopic cylinder 2 is connected to one end of the baffle door 6.

[0035] By setting the baffle 6, when the PET bottles are dried, the electric telescopic cylinder 2 starts to work and pulls the baffle 6 upward, so that the PET bottles enter the conveyor belt under the push of the rotating push plate 1 and start to be conveyed.

[0036] In order to identify the bottle color and control the motor of the lever, such as Figure 1 As shown in Figure 2, an identification device 8 is provided on one side of the sorting device body 18, and the identification device 8 includes an image recognition module, an image analysis module and a control module.

[0037] By setting the recognition device 8, when the sorting device body 18 is in operation, the image recognition module collects the image of the PET bottle, analyzes the characteristics of the PET bottle based on the image analysis module, and transmits the information to the control module; the image recognition module can adopt a common image recognition device on the market, such as a CCD image acquisition device, etc., to recognize the information characteristics such as the color and / or size of the PET bottle, and the control module controls the motor of the corresponding lever 9 to work according to the recognized characteristics, thereby driving the lever 9 to move; the image recognition module and the control module belong to the existing technology, so they are not described here.

[0038] To reduce the stacking of PET bottles, such as Figure 1 As shown, a slope conveyor belt 7 is provided at one end of the identification device 8 away from the feed box 11 .

[0039] By setting up the slope conveyor belt 7, the PET bottles have to pass through the slope conveyor belt 7 before entering the identification device 8. When the PET bottles stacked on the upper part reach a certain height, they will return to the original point due to unstable factors and be conveyed again. This not only controls the number of PET bottles to be detected, but also prevents them from stacking, creating conditions for subsequent detection and the movement of the lever 9.

[0040] Working principle: when the PET bottles are washed and soaked in the washing room 3, the motor 5 starts to operate, driving the rotating push plate 1 to rotate and push the PET bottles to make them fully washed; after washing, the water pump pumps the water in the washing room 3 into the water pumping tank 4; the dryer 12 starts to work to dry the PET bottles. During this period, the rotating push plate 1 has been pushing the bottles, so that the bottles are not only fully washed, but also the water can be fully drained. The final push makes the bottles fully dried; when the PET bottles are dried, the electric telescopic cylinder 2 starts to work and pulls the baffle 6 upwards, so that the PET bottles enter the conveyor belt under the push of the rotating push plate 1 and begin to be conveyed to the slope conveyor belt 7. When the PET bottles stacked on the upper part of the bottle body reach a certain height on the slope conveyor belt 7, they will be unstable. The PET bottles are returned to the origin due to the above factors and are transported again, which not only controls the number of PET bottles detected, but also prevents them from stacking. After being transported to the identification device 8 by the slope conveyor belt 7, the intelligent sorting machine starts to detect the PET bottles. The image recognition module collects the image of the PET bottles, analyzes the characteristics of the PET bottles based on the image analysis module, and transmits the information to the control module. The control module controls the motor of each lever 9 to drive the lever 9 to move. When the lever 9 moves the bottle, the blocking tube 13 can prevent the bottle from rolling to the other side of the lever 9 before reaching the feed port. In addition, the blocking tube 13 is detachably installed on the upper end of the first rod body 14, and can be disassembled according to the stacking situation of the PET bottles to control the distribution density of the PET bottles, so that the lever 9 can be effectively moved.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
