On the upper end of the support frame 1 on the output side of the first-stage vibrating conveying frame 9, a second-stage vibrating conveying frame 11 is installed. The input end of the second-stage vibrating conveying frame 11 receives the food packaging conveyed by the output end of the first-stage vibrating conveying frame 9. The vibrating speed of the second-stage vibrating conveying frame 11 is greater than that of the first-stage vibrating conveying frame 9. On the upper end of the support frame 1 on the output side of the second-stage vibrating conveying frame 11, a third-stage vibrating conveying frame 12 is installed. Each conveying frame on the third-stage vibrating conveying frame 12 is in a V shape. The input end of the third-stage vibrating conveying frame 12 receives the food packaging conveyed by the output end of the second-stage vibrating conveying frame 11. The input end of the receiving conveyor belt 2 receives the food packaging output by the third-stage vibrating conveying frame 12. The vibrating speed of the third-stage vibrating conveying frame 12 is greater than that of the second-stage vibrating conveying frame 11. The output end of the first-stage vibrating conveying frame 9 is provided with a sweeping component for reducing the passing amount of food packaging. The third-stage vibrating conveying frame 12 is provided with a detection and flipping component for detecting the front and back of the food packaging and flipping the food packaging.

[0026] The sweeping component includes a silica gel sweeping wheel 8, which is horizontally arranged above the output end of the first-stage vibrating conveying frame 9. The blades of the silica gel sweeping wheel 8 convey the food packaging. Both ends of the silica gel sweeping wheel 8 are rotatably connected to a bracket 7 for supporting the silica gel sweeping wheel 8. The lower end of the bracket 7 is installed on the upper end of the support frame 1. One end of the silica gel sweeping wheel 8 passes through the bracket 7 and is installed with a motor 10 for driving the silica gel sweeping wheel 8 to rotate. The motor 10 is installed on the side wall of the bracket 7.

[0027] The detection and flipping assembly includes a mounting frame 5. On the side wall of each conveying frame of the three-stage vibrating conveying frame 12, there is installed a blowing nozzle 14 for blowing the food packaging to flip. Above the blowing nozzle 14, an auxiliary blowing pipe 13 is horizontally arranged. The two ends of the auxiliary blowing pipe 13 are connected to the upper end of the support frame 1 through a connecting plate. At the lower end of the auxiliary blowing pipe 13, there are installed auxiliary blowing nozzles corresponding to each conveying frame on the three-stage vibrating conveying frame 12 one by one.

[0028] On the side wall of the three-stage vibrating conveying frame 12 on the side of the blowing nozzle 14 away from the receiving conveyor belt 2, there is installed an optical fiber sensor 15 for detecting the food packaging. The mounting frame 5 is arranged directly above the three-stage vibrating conveying frame 12. The mounting frame 5 is connected to the fixing frame of the receiving conveyor belt 2. On the side wall of the mounting frame 5, there is installed a camera 3 for taking pictures of the food packaging on the three-stage vibrating conveying frame 12. At the upper end of the mounting frame 5, there is installed a computer 4 for receiving the data signals of the optical fiber sensor 15 and the camera 3 and controlling the blowing nozzle 14.

[0029] The working principle of a food packaging front and back flipping system:

[0030] During use, the belt elevator 6 lifts and conveys the food packaging. The belt elevator 6 conveys the food packaging to the input end of the first-stage vibrating conveying frame 9. Due to vibration, the food packaging on the first-stage vibrating conveying frame 9 moves downward. Then, the motor 10 is started. The output end of the motor 10 drives the silicone sweeping wheel 8 to rotate. The blades of the silicone sweeping wheel 8 block and convey the food packaging, controlling the number of food packaging conveyed to the second-stage vibrating conveying frame 11.

[0031] After the food packaging is conveyed to the second-stage vibrating conveying frame 11, since the vibration speed of the second-stage vibrating conveying frame 11 is greater than that of the first-stage vibrating conveying frame 9, the spacing between the food packaging on the second-stage vibrating conveying frame 11 will become larger, and the food packaging is conveyed to the third-stage vibrating conveying frame 12.

[0032] Since each conveying frame on the third-stage vibrating conveying frame 12 is in a V shape, one side of the food packaging will stick to one of the side walls of the V shape. Since the vibration speed of the third-stage vibrating conveying frame 12 is greater than that of the second-stage vibrating conveying frame 11, the spacing between the food packaging will further become larger.

[0033] When the optical fiber sensor 15 detects the food packaging, the optical fiber sensor 15 sends a signal to the computer 4. The computer 4 controls the camera 3 to take pictures. Then, the camera 3 conveys the photo data to the computer 4 for analysis. If the upward side of the food packaging is the reverse side, the computer 4 controls the blowing nozzle 14 on the side wall where the food packaging is located to blow the food packaging, so that the food packaging flips to the other side wall of the V-shaped conveying frame, thus realizing the turning over. Finally, the third-stage vibrating conveying frame 12 conveys the food packaging to the receiving conveyor belt 2.

[0034] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model.
