[0003] In the process of extracting essential oils in cosmetics processing, feeding equipment occupies a vital position, and its performance directly affects the extraction efficiency, product quality, and production cost. In the traditional essential oil extraction process, the feeding equipment usually adopts the auger feeding method, however, this traditional method has obvious limitations. Specifically, first of all, the conveyed raw materials (petals) are prone to adhesion on the inner wall of the conveying barrel, which is difficult to clean, and then cause the raw materials to rot in the barrel, pollute the conveying barrel, and are not conducive to the long-term use of the equipment. Secondly, the traditional feeding equipment fails to effectively recycle the heat generated during the extraction process, resulting in significant energy waste. Moreover, the flower stems remaining in the petals cannot be removed, which reduces the purity of the raw materials for essential oil extraction. Summary of the invention

In addition, the preheating system is used to preheat the petals, which further promotes the activity of the essential oil molecules, making the extraction process more efficient and thorough; During the heating process, the heat in the extraction tank is absorbed by the heat absorbing plate and released to the petals in the conveying cylinder for preheating in a timely manner, which not only reduces the dependence on new heat sources, but also avoids the ineffective loss of heat energy, thus achieving the goal of energy saving and emission reduction. In addition, while preheating the petals, the hot air can also remove the petals stuck on the inner wall of the conveying cylinder, keep the equipment clean, extend the service life of the equipment, reduce maintenance costs, and achieve maximum utilization of resources; The invention realizes the whole process from breaking up, separating and conveying the petals to heating extraction in the extraction tank and then recycling and utilizing the heat energy through mechanical transmission and intelligent control. This not only reduces the labor intensity and the risk of human operation errors, but also improves the stability and reliability of the entire production process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention.

[0021] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0022] Please refer to the attached Figure 1-Figure 13 As shown, this embodiment provides a feeding device for essential oil extraction, including an extraction tank 1 and a processing box 2, a controller 5 is installed on the extraction tank 1, and a discharge trough 21 and a slag discharge trough 22 are respectively opened on both sides of the processing box 2, and also includes: A pre-treatment mechanism 3, the pre-treatment mechanism 3 is arranged in the treatment box 2; The conveying mechanism 4 is arranged between the extraction tank 1 and the processing box 2, and the conveying mechanism 4 includes a feeding part 41 and a linkage part 42. When the pretreatment mechanism 3 is in operation, the linkage part 42 drives the feeding part 41 to operate and transport the pretreated raw materials to the extraction tank 1; A heat recovery mechanism 6, which is disposed on the extraction tank 1 and is used to recover heat energy generated during the extraction process; The heat recovery mechanism 6 includes an air supply unit 61 , which is disposed on the extraction tank 1 , a driving unit 62 is disposed at the bottom of the extraction tank 1 , and an air inlet unit 63 and a control unit 64 are also disposed on the air supply unit 61 .

[0023] In this embodiment, the heat recovery mechanism 6 significantly improves the energy utilization efficiency during the essential oil extraction process. The air supply unit 61 ensures that the hot air generated during the extraction process can be effectively introduced into the feed unit 41. The drive unit 62 is located at the bottom of the extraction tank 1, providing a stable power source for the entire heat recovery system.

[0024] The air inlet 63 ensures that air can enter evenly; the control unit 64 ensures the orderly operation of the heat recovery mechanism 6.

[0025] In the extraction tank 1, the raw materials processed by the pretreatment mechanism 3 are accurately fed in through the feeding part 41 of the conveying mechanism 4. The ingenious design of the linkage part 42 enables the feeding part 41 to operate synchronously with the operation of the pretreatment mechanism 3, ensuring the continuous supply and efficient conveying of the raw materials.

[0026] It should be added that the extraction tank 1 adopts a product currently available on the market, which will not be described in detail here. When selecting a model, the specifications and usage scenarios should be suitable, and the specific model specifications should be selected to meet the requirements of this application. In addition, the gas outlet provided on the extraction tank 1 should be connected to subsequent equipment for subsequent extraction work.

[0027] Next, please refer to Figure 1-Figure 4 The pre-treatment mechanism 3 includes two rotating rods 301, which are rotatably connected to the treatment box 2 through bearings. The rotating rods 301 are provided with bulk material parts 302 in an array. A trapezoidal seat 303 is fixedly connected to the inner wall of one side of the treatment box 2. The trapezoidal seat 303 is provided with ventilation slots 304 in an array, and a fan 305 is installed on the inner wall of the ventilation slots 304. A guide plate 306 is fixedly connected to the inner wall of the other side of the treatment box 2. One end of the rotating rod 301 is fixedly connected to the first transmission gear 30 7. A rotating motor 308 is fixedly installed on the front of the processing box 2, and the output shaft of the rotating motor 308 is fixedly connected to the central rotating shaft of one of the rotating rods 301; wherein, the bulk material part 302 includes a U-shaped seat 3021, the U-shaped seat 3021 is fixedly connected to the rotating rod 301, a striking rod 3022 is rotatably connected to the U-shaped seat 3021, and one end of the striking rod 3022 close to the rotating rod 301 is fixedly connected to a metal spring 3023, and the other end of the metal spring 3023 is fixedly connected to the U-shaped seat 3021.

[0028] In this embodiment, the petals are poured into the processing box 2, and the rotating motor 308 is started to drive one of the rotating rods 301 to rotate, and the first transmission gear 307 at the rear end of the two rotating rods 301 realizes the synchronous rotation of the two rotating rods 301. The rotation of the rotating rod 301 drives the bulk material part 302 to rotate and hit the petals, so as to achieve the scattering of the petals and the separation of the adhered petals, as well as the separation of the flower stems and the petals, which facilitates the subsequent screening work. The scattered petals fall downward under the action of gravity, and the fan 305 is started to blow air at the same time. The petals move to the guide plate 306 under the action of the airflow generated by the fan 305, and then are discharged from the discharge trough 21 along the guide plate 306. The flower stems or other heavier impurities fall directly to the bottom due to their own weight and are discharged through the slag discharge trough 22, thereby removing the flower stems or heavy impurities remaining in the petals, ensuring the purity of the subsequent essential oil extraction.

[0029] The bulk material part 302 is composed of a U-shaped seat 3021, a striking rod 3022 and a metal spring 3023. The metal spring 3023 gives the striking rod 3022 a certain buffering property to prevent the flower stems from being broken, improve the integrity of the flower stems, ensure the weight of the flower stems, and facilitate subsequent screening work.

[0030] It should be added that, in this embodiment, five fans 305 are provided (but not limited to this).

[0031] Next, please refer to Figure 2-Figure 3 and Figure 6-Figure 8 The feeding part 41 includes a conveying cylinder 411, which is connected to the extraction tank 1, and the other end of the conveying cylinder 411 is fixedly connected to a feed cover 412, and the feed cover 412 is connected to one side of the processing box 2. A first round rod 413 is arranged inside the conveying cylinder 411, and a spiral blade 414 is fixedly sleeved on the outer wall of the first round rod 413. Among them, the linkage part 42 includes a second round rod 421, and the back of the processing box 2 is rotatably connected to the second round rod 421 by a bracket. A first bevel gear 422 is fixedly installed at one end of the second round rod 421, and a second bevel gear 423 is fixedly installed at the rear end of one rotating rod 301, and a second transmission gear 424 is fixedly connected to the other end of the second round rod 421. A cylinder 425 is fixedly connected between the left and right sides of the processing box 2, and one end of the first round rod 413 is rotatably connected in the cylinder 425, and a third transmission gear 426 is fixedly installed at one end of the first round rod 413 away from the spiral blade 414.

[0032] In this embodiment, the petals discharged from the discharge trough 21 enter the conveying cylinder 411 through the feed cover 412. The rotation of the rotating rod 301 simultaneously drives the second bevel gear 423 to rotate, and the second round rod 421 is driven to rotate through the meshing transmission of the second bevel gear 423 and the first bevel gear 422. The rotation of the second round rod 421 drives the second transmission gear 424 to rotate, and the third transmission gear 426 and the first round rod 413 are driven to rotate through the toothed belt transmission, thereby driving the spiral blade 414 to rotate, and the petals in the conveying cylinder 411 are transported to the extraction tank 1 for extraction.

[0033] Please refer again Figure 5-Figure 10 The air supply part 61 includes a hollow cylinder 611, which is arranged on the extraction tank 1 in a ring-shaped distribution. The upper end of the hollow cylinder 611 is connected with an air outlet pipe 612, and the other end of the plurality of air outlet pipes 612 is connected with an annular tube 613, and the annular tube 613 is connected with a conveying pipeline 614. An annular groove 615 is provided on the conveying cylinder 411, and the inner circle of the annular groove 615 is provided with air outlet holes 616 in an array distribution. The lower end of the hollow cylinder 611 is rotatably connected with a third round rod 617, and a fan blade 618 is fixedly installed on the upper end of the third round rod 617. A guide plate 619 is provided on the inner wall of the hollow cylinder 611.

[0034] In this embodiment, the third round rod 617 rotates to drive the fan blade 618 to rotate for blowing. The air enters the hollow cylinder 611 through the air inlet 63 (the hollow cylinder 611 is in contact with the high-temperature medium inside the extraction tank 1, and the heat can be transferred to the hollow cylinder 611, thereby heating the internal air), and after heating, enters the annular tube 613 along the air outlet pipe 612, and then enters the annular groove 615 through the conveying pipe 614, and finally ejects from the air outlet 616. The ejected hot air preheats the petals, and at the same time removes the petals stuck on the inner wall of the conveying cylinder 411, which can recover the heat generated during extraction and keep the conveying cylinder 411 clean.

[0035] It should be added that the guide plate 619 adopts a staggered distribution design layout, which is intended to effectively extend the air flow path in the hollow tube 611, thereby increasing the contact time between the air and the heating source, ensuring that the air is evenly and fully heated, thereby ensuring the stability and consistency of the heating effect.

[0036] Please refer again Figure 6-Figure 10 The driving part 62 includes a mounting groove 621, which is opened at the lower end of the extraction tank 1. The bottom surface of the inner cavity of the mounting groove 621 is rotatably connected with a double-ring gear 622. A driving motor 623 is fixedly installed on the bottom surface of the extraction tank 1. The upper end of the output shaft of the driving motor 623 passes through the mounting groove 621 and is installed with a driving gear 624. The lower end of the third round rod 617 is fixedly connected with a fourth transmission gear 625.

[0037] In this embodiment, after the driving motor 623 is started, it drives the driving gear 624 to rotate, and the double ring gear 622 is driven to rotate by the meshing transmission between the driving gear 624 and the inner ring of the double ring gear 622. The outer ring of the double ring gear 622 meshes with the fourth transmission gear 625 to drive the third round rod 617 to rotate.

[0038] Please refer again Figure 11-Figure 12 The air inlet part 63 includes an air inlet pipe 631, which is connected to the lower end of the hollow cylinder 611. The other end of the air inlet pipe 631 is threadedly connected with a filter cover 632. The inner wall of the air inlet pipe 631 is fixedly connected with a hollow ring 633 and a support 634. The support 634 is slidably connected with a plug rod 635. One end of the plug rod 635 is fixedly connected with a first blocking plate 636, and the other end of the plug rod 635 is fixedly connected with an iron block 637. The outer wall of the plug rod 635 is sleeved with a compression spring 638, and the inner wall of the air inlet pipe 631 is also fixedly installed with an electromagnet 639.

[0039] In this embodiment, the suction force generated by the electromagnet 639 after being energized drives the iron block 637 to move, thereby moving the insertion rod 635, causing the first blocking plate 636 to move away from the hollow ring 633 and compress the compression spring 638. At this time, outside air enters through the gap between the hollow ring 633 and the first blocking plate 636.

[0040] The filter cover 632 is detachably threadedly connected to one end of the air inlet pipe 631. Due to its easy cleaning and maintenance, the device can be kept in good condition during long-term use.

[0041] Please refer again Fig.10 and Fig.13 The control unit 64 includes a heat-conducting seat 641, which is fixedly connected to the upper end of the hollow cylinder 611, and one end of the heat-conducting seat 641 extends into the extraction tank 1. A heat-absorbing plate 642 is fixedly connected to the heat-conducting seat 641. The top surface of the heat-conducting seat 641 is provided with grooves in a circular shape, and a spring 643 is fixedly connected in the groove. The upper end of the spring 643 is fixedly connected to a second blocking plate 644. A touch switch 645 is also installed at the upper end of the hollow cylinder 611.

[0042] In this embodiment, the heat inside the extraction tank 1 is absorbed by the heat absorbing plate 642 and transferred to the heat conducting seat 641. When the heat accumulates to a certain extent, the spring 643 made of memory alloy deforms, pushing the second blocking plate 644 upward, forming a gap between the heat conducting seat 641 and the second blocking plate 644, allowing air circulation. As the second blocking plate 644 continues to move upward, the touch switch 645 is triggered, and the controller 5 immediately starts the drive motor 623 and energizes the electromagnet 639.

[0043] It should be added that after the extraction is completed, the extraction tank 1 stops heating, and the heat in the hollow cylinder 611 and the heat absorbing plate 642 is gradually dissipated. When the temperature drops to a preset value, the spring 643 drives the second blocking plate 644 to move down and contact the heat-conducting seat 641, close the upper air outlet channel, and leave the touch switch 645. Then the controller 5 turns off the drive motor 623 and disconnects the power supply of the electromagnet 639. The fan blade 618 stops rotating and the air stops flowing. The iron block 637 is reset under the action of the compression spring 638, and the first blocking plate 636 contacts the hollow ring 633 to achieve blocking, preventing outside air from entering from the air inlet pipe 631, preventing the inside of the hollow cylinder 611 from getting damp and producing odor, and maintaining its cleanliness.

[0044] When the extraction tank 1 just starts to be heated and the temperature is low, the spring 643 will not be deformed, the first blocking plate 636 and the hollow ring 633 block the air inlet end, and the second blocking plate 644 contacts the heat conductive seat 641 to block the air outlet end, and the hot air in the hollow tube 611 cannot flow out, thereby reducing heat loss and accelerating the increase in the internal temperature of the extraction tank 1.

[0045] It should be noted that the spring 643 is made of a memory alloy and can be deformed by temperature. When the temperature rises, the spring 643 will gradually stretch, pushing the second sealing plate 644 upward to form a gap between the heat conducting seat 641 and the second sealing plate 644 .

[0046] When the temperature inside the extraction tank 1 reaches a preset value, the extension force of the spring 643 will be just balanced with the deadweight and resistance of the second blocking plate 644. In addition, the deformation process of the memory alloy spring 643 is also reversible. When the extraction tank 1 stops heating and the temperature gradually decreases, the spring 643 will gradually return to its original shape, driving the second blocking plate 644 to move downward, re-contact the heat-conducting seat 641, and close the upper air outlet channel. This design not only ensures the efficient operation of the system, but also greatly extends the service life of the equipment.

[0047] During the whole process, the controller 5 monitors the state of the touch switch 645 to achieve precise control of the drive motor 623 and the electromagnet 639 .

[0048] A method for extracting essential oil for cosmetics, applied to the above-mentioned feeding equipment for extracting essential oil, comprises the following steps: Step 1: first pour the petals into the processing box 2, and start the pre-processing mechanism 3 to remove the flower stems or weight impurities remaining in the petals; Step 2: The pre-treated petals are transported to the extraction tank 1 through the conveying mechanism 4 for extraction; Step 3: When the heat inside the extraction tank 1 accumulates to a certain extent, the spring 643 made of memory alloy is deformed, pushing the second blocking plate 644 upward; as the second blocking plate 644 continues to move upward, the touch switch 645 is triggered; Step 4: the controller 5 starts the driving motor 623 and energizes the electromagnet 639. At this time, the outside air enters through the gap between the hollow ring 633 and the first blocking plate 636. After the driving motor 623 is started, it drives the fan blades 618 to rotate to blow air, and the hot air in the hollow cylinder 611 is blown into the conveying cylinder 411 through the set pipeline, so as to complete the cleaning of the conveying cylinder 411 and preheat the petals in the conveying cylinder 411. Step 5: After the extraction is completed, the extraction tank 1 stops heating, and the heat in the hollow cylinder 611 and the heat absorbing plate 642 gradually dissipates. When the temperature drops to a preset value, the spring 643 drives the second blocking plate 644 to move down and contact the heat conducting seat 641, closing the upper air outlet channel and leaving the touch switch 645; then the controller 5 turns off the driving motor 623 and disconnects the power supply of the electromagnet 639. The fan blade 618 stops rotating and the air stops flowing.

[0049] The working principle of the present invention is: First, a proper amount of clean water is poured into the extraction tank 1 and heated.

[0050] Next, the petals are poured into the processing box 2, and the rotating motor 308 is started to drive one of the rotating rods 301 to rotate, and the first transmission gear 307 at the rear end of the two rotating rods 301 realizes the synchronous rotation of the two rotating rods 301. The rotation of the rotating rod 301 drives the bulk material part 302 to rotate and hit the petals, so as to achieve the separation of the petals and the separation of the petals, and the separation of the flower stems and the petals, which facilitates the subsequent screening work. The scattered petals fall downward under the action of gravity, and the fan 305 is started to blow air at the same time. The petals move to the guide plate 306 under the action of the airflow generated by the fan 305, and then are discharged from the discharge trough 21 along the guide plate 306. The flower stems or other heavier impurities fall directly to the bottom due to their own weight and are discharged through the slag discharge trough 22, thereby removing the incomplete flower stems or weight impurities remaining in the petals, and ensuring the purity of the subsequent essential oil extraction.

[0051] The petals discharged from the discharge trough 21 enter the conveying cylinder 411 through the feed cover 412. The rotation of the rotating rod 301 drives the second bevel gear 423 to rotate at the same time, and the second round rod 421 is driven to rotate through the meshing transmission of the second bevel gear 423 and the first bevel gear 422. The rotation of the second round rod 421 drives the second transmission gear 424 to rotate, and the third transmission gear 426 and the first round rod 413 are driven to rotate through the toothed belt transmission, thereby driving the spiral blade 414 to rotate, and the petals in the conveying cylinder 411 are transported to the extraction tank 1 for extraction.

[0052] The heat inside the extraction tank 1 is absorbed by the heat absorbing plate 642 and transferred to the heat conductive seat 641. When the heat accumulates to a certain extent, the spring 643 made of memory alloy is deformed, pushing the second blocking plate 644 to move upward, forming a gap between the heat conductive seat 641 and the second blocking plate 644, allowing air circulation. As the second blocking plate 644 continues to move upward, the touch switch 645 is triggered, and the controller 5 immediately starts the drive motor 623 and energizes the electromagnet 639. The suction force generated by the electromagnet 639 drives the iron block 637 to move, and then moves the rod 635, causing the first blocking plate 636 to move away from the hollow ring 633 and squeeze the compression spring 638. At this time, outside air enters through the gap between the hollow ring 633 and the first blocking plate 636.

[0053] After the driving motor 623 is started, it drives the driving gear 624 to rotate, and the double ring gear 622 is driven to rotate by the meshing transmission between the driving gear 624 and the inner ring of the double ring gear 622. The outer ring of the double ring gear 622 is meshed with the fourth transmission gear 625 to drive the third round rod 617 to rotate, thereby driving the fan blade 618 to rotate for blowing. The air enters the hollow cylinder 611 through the air inlet pipe 631, enters the annular pipe 613 along the air outlet pipe 612 after being heated, and then enters the annular groove 615 through the conveying pipe 614, and finally ejects from the air outlet 616. The ejected hot air preheats the petals, and at the same time removes the adhered petals on the inner wall of the conveying cylinder 411, which can recover the heat generated during extraction and keep the conveying cylinder 411 clean.

[0054] After the extraction is completed, the extraction tank 1 stops heating, and the heat in the hollow cylinder 611 and the heat absorbing plate 642 gradually dissipates. When the temperature drops to the preset value, the spring 643 drives the second blocking plate 644 to move down and contact the heat-conducting seat 641, close the upper air outlet channel, and leave the touch switch 645. Then the controller 5 turns off the drive motor 623 and disconnects the power supply of the electromagnet 639. The fan blade 618 stops rotating and the air stops flowing. The iron block 637 is reset under the action of the compression spring 638, and the first blocking plate 636 contacts the hollow ring 633 to achieve blocking, preventing outside air from entering from the air inlet pipe 631, preventing the inside of the hollow cylinder 611 from getting damp and producing odor, and maintaining its cleanliness.

[0055] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
