Description

Technical Field

[0001] This utility model relates to the field of sorting machinery technology, and more specifically, to an organic rose petal sorting device. Background Technology

[0002] Currently, rose petals are widely used in the fields of organic food and high-end cosmetics due to their rich natural active ingredients. For example, rose essential oil skin care products, rose jam, rose preserves and other products require the rose petal raw materials to be sorted for impurities before processing, that is, to remove foreign objects such as coarse branches, flower stems, rotten petals, and miscellaneous leaves. They also need to meet the organic processing standards of no artificial pollution, low loss, and high precision.

[0003] Currently, the sorting of organic rose petals mainly relies on two methods: traditional manual sorting and existing mechanized sorting equipment. Both methods have significant technical drawbacks: traditional manual sorting of organic rose petals is inefficient, has high labor costs, is prone to introducing external contamination, and lacks sorting accuracy. On the other hand, existing mechanized sorting equipment has problems with low sorting accuracy, cannot effectively distinguish impurities that are similar to the characteristics of the petals, is easily misjudged due to the humidity of the petals, and lacks sorting, conveying, and collection functions.

[0040] The operating procedure for this device is as follows: 1. Raw material feeding: Slowly pour the organic rose raw materials to be sorted into the funnel-shaped hopper 3 of the pretreatment module to avoid excessive feeding at one time; 2. Automatic screening and flow restriction: The 304 stainless steel square grid screen 5 inside the hopper 3 intercepts large impurities such as coarse branches with a diameter larger than the grid size. The large impurities remaining on the grid can be cleaned manually periodically. The vibration motor 4 is started under the control of PLC, driving the hopper 3 to vibrate slightly. The raw material slides evenly along the inner wall of the hopper 3 to the outlet. If the infrared beam sensor detects that an oversized impurity such as a long flower stem is stuck at the outlet, it immediately sends a signal to the PLC. The PLC controls the vibration motor 4 to stop and triggers an audible and visual alarm. The machine resumes operation after the impurities are cleaned manually.

[0041] 3. Multi-dimensional sorting stage: The pre-treated raw materials enter the feed inlet at the left end of the air-powered sorting chamber 7 through the stainless steel channel. The high-frequency capacitive humidity sensor 8 detects the humidity of the petals and feeds it back to the PLC. If the humidity is <85%RH, the petals are dry. The PLC controls the dual-speed motor 9 to run at a low speed, and the fan blades 10 generate a weak wind. If the humidity is ≥85%RH, the petals are wet. The dual-speed motor 9 switches to a high speed, and the wind power is increased. The adjustable air guide plate 11 guides the air force to transport the sorting chamber 7 to the right end. Lightweight high-quality petals move to the right end discharge port with the airflow, while heavy impurities such as rotten petals and small mud lumps fall down the chamber wall to the bottom main waste outlet 13. The high-pressure air nozzle 14 in the main waste outlet 13 sprays air periodically to prevent impurities from adhering and clogging. Petals containing a small amount of light impurities enter the right end of the sorting chamber 7 and pass through the image recognition area. The industrial camera 15 starts shooting, and the ring LED fill light 16 is turned on simultaneously to provide fill light. The image signal is transmitted to the PLC in real time. The built-in algorithm identifies impurities such as dry leaves, broken and rotten petals, which are dark in color and irregular in shape. The corresponding high-speed electromagnetic jet valve 17 is immediately controlled to blow the impurities into the side secondary waste outlet 20. The impurities fall into the waste collection box 27 through an independent channel. The high-quality petals after screening continue to move towards the discharge port at the right end of the sorting chamber 7 and enter the petal buffer chamber 33.

[0042] 4. Flexible conveying and quantitative collection stage: The silicone soft guide curtain 34 in the petal buffer chamber 33 slows down the falling speed of the petals to prevent them from breaking due to impact; the infrared counting sensor 35 counts the number of petals falling and feeds it back to the PLC. The PLC adjusts the speed of the servo motor 25 of the flexible conveying unit. When there are many petals, the speed is increased and when there are few petals, the speed is decreased to ensure that the petals on the conveyor belt 22 are evenly distributed and do not accumulate; the petals are conveyed to the discharge end by the conveyor belt 22 and fall naturally into the weighing collection box 27 below. The pressure sensor 29 of the discharge plate 28 at the bottom of the collection box 27 detects the weight in real time. When the weight reaches the preset quantitative value of the PLC, the pressure sensor 29 sends a signal to the PLC, and the PLC controls the push cylinder 30 of the automatic box opening mechanism to push the empty carton 32 from the carton placement rack 31 to the bottom of the collection box 27. At the same time, it controls the unloading plate 28 at the bottom of the collection box 27 to open, and the full carton of petals falls into the empty carton 32. After the empty carton 32 is received, the pusher cylinder 30 is reset, and the full carton is automatically conveyed to subsequent processing steps such as washing and drying. The PLC triggers the next round of empty carton 32 push, realizing uninterrupted quantitative collection.

[0043] 5. Shutdown phase: After the raw materials are sorted, once the petals in the conveyor belt 22 and collection box 27 have been completely conveyed or collected, the control system will gradually shut down in the following order: first stop the raw material conveying, then stop the sorting components, and finally stop the control module, to prevent residual petals from deteriorating inside the equipment.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
