Description

Technical Field

[0001] This utility model relates to the field of zongzi leaf screening technology, specifically, to a zongzi leaf grading and screening device. Background Technology

[0002] Bamboo leaves are an essential ingredient in "zongzi," the food eaten on the Dragon Boat Festival. Scientifically known as *Imperata cylindrica* leaves, they contain abundant chlorophyll and various amino acids beneficial to the human body, and have a fragrant aroma that evokes a sense of returning to nature. Bamboo leaves are not only used for wrapping zongzi, but also for packaging other foods, serving as table decorations and garnishes, weaving utensils, making lunch boxes, and cutting them into various shapes. Because bamboo leaves grow naturally, are non-toxic, pollution-free, and can be harvested year after year, season after season, they possess the characteristics of being "disposable" and pollution-free, thus playing an irreplaceable role in the food packaging industry.

[0003] The processing of zongzi leaves requires pre-treatment such as screening and grading after harvesting, followed by drying, storage, and transportation before they can be sold and used in the market. Currently, the screening and grading of zongzi leaves rely entirely on manual labor, which is difficult to do effectively and accurately with the naked eye. A zongzi leaf grading and screening device is needed to solve this problem. Utility Model Content

[0020] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0021] Example 1

[0022] refer to Figures 1 to 2 Example 1 describes a device including a base 1 located at the bottom of the entire device. An angle adjustment assembly is installed inside the base 1, and a cylinder 17 is mounted on the angle adjustment assembly. A pneumatic rod 18 is mounted on the output end of the cylinder 17, and the other side of the cylinder 17 is fixedly mounted on a stop block 19. A connecting block 22 is fixedly mounted on the stop block 19, and a moving rod 3 is fixedly mounted on the top of the connecting block 22. An adjusting plate 4 is slidably connected to the moving rod 3, and a conveying device 5 is mounted on the adjusting plate 4. A detection box 6 is fixedly mounted on the conveying device 5, and an alarm 7 is mounted on the top of the detection box 6. The measuring box 6 is equipped with a rectangular fiber optic probe 11 and a control module 12. A graded storage box 10 is provided on one side of the conveying device 5. The graded storage box 10 is rectangular. A support column 16 is fixedly installed on the base 1. The support column 16 is located on the U-shaped part 13 at the bottom of the adjusting plate 4. The U-shaped part 13 and the support column 16 are rotatably connected by a rotating shaft 14. A conveyor belt 8 is installed on the conveying device 5. A panel 9 is fixedly installed on the front of the conveying device 5. The rectangular fiber optic probe 11 and the cylinder 17 are controlled by the panel 9. The control module 12 consists of a main control chip and a battery.

[0023] In this embodiment, the detection box 6 uses an internal rectangular fiber optic probe 11 to detect a single zongzi leaf. The length and width of the zongzi leaf are calculated based on the time it takes to pass through the rectangular fiber optic probe 11 and the speed at which the zongzi leaf is transported, thereby identifying whether the detected zongzi leaf is qualified.

[0024] Example 2

[0025] refer to Figures 2 to 3 Example 2 is described below. This embodiment further describes Example 1. It includes a connecting block 22 on the angle adjustment assembly that passes through the slot 2 on the base 1 and connects to the moving rod 3. The moving rod 3 is slidably connected to the bottom slide rail of the adjustment plate 4 through a sliding protrusion. A slider 20 is fixedly installed at the bottom of the stop block 19. A slide groove 21 is provided in the base 1. The slide groove 21 is slidably connected to the slider 20 at the bottom of the stop block 19.

[0026] In this embodiment, the angle adjustment component is set to adjust the position of the moving rod 3 at the top of the connecting block 22 on the stop block 19 by driving the air rod 18 through the cylinder 17, thereby adjusting the angle of the conveying device 5.

[0027] In practical applications, the grading and screening device of this apparatus places the zongzi leaves to be graded and screened in the grading storage box 10. The zongzi leaves to be screened are manually placed onto the conveyor belt 8 on the conveyor device 5. The conveyor device 5 is located on the angle adjustment component. The cylinder 17 drives the air rod 18 to adjust the position of the moving rod 3 at the top of the connecting block 22 on the stop block 19, thereby adjusting the angle of the conveyor device 5 according to actual needs. The zongzi leaves pass through the detection box 6 and are detected by the internal rectangular fiber optic probe 11. The length and width of the zongzi leaves are calculated based on the time it takes to pass through the rectangular fiber optic probe 11 and the speed at which the zongzi leaves are conveyed, thereby identifying whether the detected zongzi leaves are qualified. The qualified value is set. When the set value is met, an alarm signal is issued by the alarm 7. The unqualified zongzi leaves are then manually selected. The qualified zongzi leaves are transported to the designated location by the conveyor device 5 for unified processing. This semi-automatic grading and screening method greatly improves efficiency compared to the traditional purely manual method.
