Description

Technical Field

[0001] The invention relates to the technical field of flower processing, and in particular to a photoelectric color sorting, impurity removal and grading device for jasmine flowers, aiming to efficiently and accurately achieve impurity removal and quality grading of jasmine flowers in the early stage of processing, and meet the flower industry's demand for high quality and standardization of jasmine flower raw materials. Background Art

[0002] As an important raw material for many products such as scented tea, spices, and cosmetics, the quality of jasmine flowers is directly related to the quality and market competitiveness of the end products. However, there are many difficulties in the primary processing stage after the jasmine flowers are picked. On the one hand, various impurities such as leaves, branches, soil, and insects are inevitably mixed in during the picking process. If these impurities are not removed in time, they will not only affect the purity of the jasmine flowers, but may also introduce microbial contamination during the subsequent processing process, reducing product quality; on the other hand, due to factors such as the growth environment and picking time, the quality of jasmine flowers varies, such as flower size, color brightness, and fragrance intensity. Traditional manual sorting methods are difficult to grade according to unified and precise standards, resulting in uneven product quality and unable to meet the strict requirements of the high-end market for the standardization of jasmine flower raw materials.

[0003] At present, although photoelectric color sorting technology has been adopted in some agricultural product processing fields, the existing general photoelectric color sorting equipment has poor applicability for jasmine flowers, which are delicate, relatively irregular in shape and have extremely high quality requirements. It has problems such as incomplete impurity removal, inaccurate grading, and easy damage to flowers. It cannot meet the growing high-quality processing needs of the jasmine flower industry.

[0030] As shown in the figure, a jasmine flower photoelectric color sorting, impurity removal and grading device comprises a main device 100, a feeding device 200 and a display assembly 300 are arranged on the top surface of the main device 100, and a photoelectric detection system 400, an air jet impurity removal device 500, a grading device 600 and a discharging device 700 are arranged inside the main device 100;

[0031] The feeding device 200 includes an external conveyor belt 201 and a track 202, wherein the external conveyor belt 201 is fixed on the circular track 202; the track 202 is fixed on the top of the main device 100, and an entrance is provided at the end of the track 202, which is connected to the inside of the main device 100; the discharging device 700 includes an internal conveyor belt, which is located inside the main device 100; the jasmine flowers enter the feeding device 200 and enter the discharging device 700 from the entrance; the track 202 is driven to rotate by a motor, and the front end of the track 202 is connected to the external conveyor of the flowers. A vibration mechanism is provided inside the main device 100, and the vibration mechanism is combined with the internal conveyor belt to ensure that the jasmine flowers can be evenly dispersed to avoid agglomeration and blockage.

[0032] The photoelectric detection system 400 is located inside the main device 100. The photoelectric detection system 400 includes a high-resolution optical camera, a multi-spectral light source, and an intelligent image processing unit. The high-resolution optical camera takes real-time photos of jasmine flowers from multiple angles. The multi-spectral light source emits light covering visible light and near-infrared light, penetrating the flowers to illuminate the internal structure, and assisting the camera in obtaining more comprehensive image data. For example, near-infrared light imaging can effectively distinguish differences in moisture content inside the flowers, providing more dimensional basis for quality grading. The intelligent image processing unit has a built-in advanced image recognition algorithm, which quickly analyzes and processes the collected images based on a deep learning model, accurately identifies impurities in jasmine flowers and flowers of different quality grades, and converts the recognition results into electrical signals for real-time transmission to the jet impurity removal device 500 and the grading device 600.

[0033] The jet impurity removal device 500 accurately locates the position of impurities in a very short time based on the signal from the photoelectric detection system. A row of micro jet nozzles arranged above the conveyor belt quickly sprays high-pressure gas to blow the impurities away from the conveyor belt. The jet direction, angle and strength of the jet nozzle can be precisely adjusted. For example, a soft side jet is used for lighter leaf impurities to make them fall to a collection tank on one side; for heavier branches or lumps of soil, the jet strength is increased and the jet angle is adjusted to be diagonally downward to ensure effective removal. The jet gas source is provided by an air compressor, the pressure is stable and can be intelligently adjusted according to the type of impurity and the processing speed to avoid excessive jetting that damages the jasmine flowers;

[0034] The grading device 600 performs grading based on the comprehensive characteristics of the jasmine flowers, such as color, size, shape and fragrance. Multiple sets of grading rollers with adjustable spacing are used to work in conjunction with the corresponding grading conveyor belt below. The surface of the grading rollers is wrapped with soft rubber to prevent scratching the flowers, and the spacing can be dynamically adjusted by an electric adjustment mechanism according to the preset flower size standard. When the flowers move forward to the grading area with the conveyor belt, flowers of different sizes will be stuck between the grading rollers with corresponding spacing and roll down to the corresponding lower-level grading conveyor belt to achieve preliminary size grading. At the same time, a highly sensitive aroma sensor array is installed above the grading area, which can detect the concentration and composition of the aroma emitted by the flowers in real time. Combined with the judgment of the color and shape by the photoelectric detection system, the quality grade of the flowers is comprehensively determined by the intelligent control system, and the flowers are further subdivided into different final grade conveyor belts to complete fine grading.

[0035] The display component 300 is located at the top of the main device 100 and is used to display the parameter configuration of each device. The display component 300 is a touch screen. A fill light 101 is also provided on the top of the main device 100.

First, install the vibrating feeder and conveyor belt bracket of the feeding device in sequence according to the equipment layout diagram, use a level to calibrate the horizontality of the bracket, firmly fix the vibrating feeder on the top of the bracket, adjust its vibration frequency and amplitude to the initial setting value, connect the conveyor belt and tighten it to the appropriate degree, and check the smoothness and speed regulation function of the conveyor belt. Next, install the photoelectric detection system, accurately install the high-resolution optical camera at the preset shooting position above the conveyor belt, adjust the camera focal length, aperture and other parameters at multiple angles, so that it can clearly capture the full view of the jasmine flowers; install a multi-spectral light source to ensure that the light evenly covers the surface of the conveyor belt, connect the light source controller and debug the emission intensity and switching timing of different bands of light; install the intelligent image processing unit in the control cabinet, connect the data transmission line between the camera and the light source, import the pre-trained image recognition model, test it with standard sample images, and fine-tune the model parameters to ensure that the recognition accuracy meets the design requirements.

[0037] When installing the jet impurity removal device, reasonably arrange the micro jet nozzles along the top of the conveyor belt, connect the jet pipe and the air compressor, adjust the initial jet direction and angle of the jet nozzle, set the air compressor pressure to a moderate value, test the jet impurity removal effect by simulating the placement of impurities, and optimize the jet parameters. For the grading device, install the grading rollers and their electric adjustment mechanisms, calibrate the initial value of the roller spacing, connect the grading conveyor belt below and debug its running speed synchronization; install the aroma sensor array above the grading area, connect the sensor signal acquisition line to the intelligent control system, calibrate the sensor with a standard gas of known aroma concentration, and set the aroma threshold and comprehensive judgment rules corresponding to different quality grades. Finally, install the discharging device, lay multiple discharging conveyor belts, connect the end collection box, debug the start, stop and speed regulation functions of the conveyor belt to ensure smooth discharging.
