[0045] The outer wall of the first transmission shaft 11 is fixedly sleeved with a first transmission wheel 12, the outer wall of the first transmission wheel 12 is movably mounted with a first transmission belt 13, the first transmission belt 13 is movably mounted on the outer wall of the third transmission wheel 15, the third transmission wheel 15 is fixedly sleeved on the outer wall of the connecting rod 17, the connecting rod 17 is symmetrically arranged on the side wall of the extraction box 1, the outer wall of the connecting rod 17 is fixedly sleeved with a first gear 16, the two first gears 16 are meshed with each other, one of the first gears 16 is meshed with a second gear 19 mounted on the side wall, the second gear 19 is fixedly sleeved on the outer wall of the second rotating rod 18, the side wall of the extraction box 1 is fixedly connected to a second motor 23, and the side wall of the second motor 23 is movably mounted with a second rotating rod 18.

[0046] Further, the driving motor 20 is started, and the driving motor 20 drives the rotating gear 21 to rotate through the rotating shaft, and the rotating gear 21 drives the rotating gear 21 to drive the movable tooth plates 9 on both sides to move, and the movable tooth plates 9 drive the guide blocks 8 to move, so that the guide blocks 8 on the upper and lower sides of the rotating gear 21 move in opposite directions, and the guide blocks 8 drive the connecting block 10 to move, and the connecting block 10 drives the displacement block 5 to move, and the displacement block 5 drives the first transmission shaft 11 to move, and the first transmission shaft 11 drives the crushing roller 25 to move, so that the two crushing rollers 25 in the extraction box 1 are moved closer to or away from each other. By controlling the driving motor 20, the distance between the two crushing rollers 25 can be adjusted. By changing the distance between the crushing rollers 25 The distance between the two crushing rollers 25 is adjusted to adjust the degree of crushing of the plants, so that the device can adjust the distance between the two crushing rollers 25 to a suitable distance according to the plant species, thereby ensuring that the plants reach a suitable degree of crushing after crushing, and avoid the situation where the distance between the crushing rollers 25 is too large, resulting in poor plant crushing effect, making it difficult for the oil to evaporate from the inside of the plant, and the essential oil cannot be effectively extracted; and avoid the situation where the distance between the crushing rollers 25 is too small, resulting in excessive crushing of the plants, causing damage to the essential oil components inside the plants, and affecting the efficiency and purity of the essential oil extraction; the device can adjust the distance between the crushing rollers 25 according to the degree of crushing required by different plants, ensuring that the plants can reach the required degree of crushing, thereby improving the adaptability of the device;

[0047] After adjusting the crushing roller 25, the plant to be extracted and purified is placed in the extraction box 1, and the second motor 23 is started. The second motor 23 drives the second rotating rod 18 to rotate, and the second rotating rod 18 drives the second gear 19 to rotate. The second gear 19 drives one of the first gears 16 to rotate, and the first gear 16 engaged with the second gear 19 drives the other first gear 16 to rotate.

The crushing roller 25 crushes the plants to prevent the outer layer of the plants from being too thick or too hard, which makes it difficult for steam to penetrate the plant material evenly, resulting in the essential oil in some plant materials being unable to be effectively extracted, affecting the essential oil extraction efficiency. The two crushing rollers 25 are driven by one motor to ensure the synchronization of the rotation of the two crushing rollers 25, avoiding uneven plant crushing caused by fine-tuning synchronization of the dual motors, and reducing energy consumption and equipment costs.

[0048] See also Figure 1 、 Figure 2 、 Figure 4 and Figure 8, an embodiment provided by the present invention: an extraction and purification device for producing plant essential oils, comprising an extraction box 1 and a spacing adjustment component, wherein a crushing roller 25 is provided in the extraction box 1, and the spacing adjustment component is used to adjust the distance between the crushing rollers 25; the outer wall of the first transmission shaft 11 is fixedly sleeved with a first transmission wheel 12, the outer wall of the first transmission wheel 12 is movably mounted with a first transmission belt 13, the first transmission belt 13 is movably mounted on the outer wall of the third transmission wheel 15, the third transmission wheel 15 is fixedly sleeved on the outer wall of a connecting rod 17, the connecting rod 17 is symmetrically arranged on the side wall of the extraction box 1, the outer wall of the connecting rod 17 is fixedly sleeved with a first gear 16, the two first gears 16 are meshed with each other, one of the first gears 16 is meshed with a second gear 19 mounted on the side wall, the second gear 19 is fixedly sleeved on the outer wall of a second rotating rod 18, the side wall of the extraction box 1 is fixedly connected to a second motor 23, and the side wall of the second motor 23 is movably mounted with a second rotating rod 18;

[0049] The first transmission belt 13 is provided with a tension adjustment component, which is used to adjust the tension of the first transmission belt 13 itself; a second transmission wheel 14 is movably mounted on the first transmission belt 13, the second transmission wheel 14 is fixedly mounted on the outer wall of the connecting shaft 7, an adjustment block 44 is movably mounted on the outer wall of the connecting shaft 7, a tension spring 45 is fixedly connected to the side wall of the adjustment block 44, a load sensor 46 is fixedly connected to the side wall of the tension spring 45, a telescopic device 47 is fixedly connected to the side wall of the load sensor 46, a guide body 4 is fixedly connected to the side wall of the telescopic device 47, the guide body 4 is symmetrically arranged on the side wall of the extraction box 1, the guide body 4 is movably sleeved on the outer wall of the adjustment block 44, and the load sensor 46 is connected to the telescopic device 47 via Bluetooth.

[0050] Furthermore, after adjusting the distance between the two crushing rollers 25, the horizontal position of the crushing rollers 25 changes, causing the horizontal position of the first transmission shaft 11 to change, thereby changing the horizontal position of the first transmission wheel 12, and further changing the distance between the first transmission wheel 12 and the third transmission wheel 15, causing the tension of the first transmission belt 13 on the first transmission wheel 12 and the third transmission wheel 15 to change;

[0051] After the distance between the first transmission wheel 12 and the third transmission wheel 15 increases, in the absence of external force, the tension of the first transmission belt 13 itself tends to increase. At this time, the pressure exerted by the first transmission belt 13 on the second transmission wheel 14 increases accordingly. The first transmission belt 13 drives the second transmission wheel 14 to move, so that the two second transmission wheels 14 tend to approach each other. The second transmission wheel 14 drives the connecting shaft 7 and the adjusting block 44, so that the adjusting block 44 stretches the tension spring 45, so that the tension of the tension spring 45 exerted on the load sensor 46 gradually increases. When the data detected by the load sensor 46 gradually increases, When the data detected by the load sensor 46 exceeds the threshold range, the load sensor 46 controls the telescopic device 47 to extend until the data detected by the load sensor 46 reaches the threshold range, thereby releasing part of the elastic force of the tension spring 45, so that the tension applied by the tension spring 45 to the adjustment block 44 gradually decreases, thereby gradually reducing the pressure applied by the second transmission wheel 14 to the first transmission belt 13, thereby gradually reducing the tension of the first transmission belt 13 itself, thereby completing the adjustment of the tension of the first transmission belt 13 itself, and avoiding excessive tension of the first transmission belt 13, which may cause the first transmission belt 13 to break;

[0052] After the distance between the first transmission wheel 12 and the third transmission wheel 15 becomes smaller, in the absence of external force, the tension of the first transmission belt 13 itself tends to decrease. At this time, the pressure applied by the first transmission belt 13 to the second transmission wheel 14 tends to decrease, so that the force applied by the adjustment block 44 to the tension spring 45 tends to decrease, and the tension spring 45 tends to return to its original state from the stretched state, thereby gradually reducing the tension applied by the tension spring 45 to the load sensor 46. When the data detected by the load sensor 46 is lower than the threshold range, the load sensor 46 controls the telescopic device 47 to contract until the data detected by the load sensor 46 reaches the threshold range, thereby causing the telescopic device 47 to stretch the tension spring 45, thereby gradually increasing the tension applied by the tension spring 45 to the adjustment block 44, and then gradually increasing the pressure applied by the second transmission wheel 14 to the first transmission belt 13, thereby gradually increasing the tension of the first transmission belt 13 itself, thereby avoiding the situation where the tension of the first transmission belt 13 itself is too low, resulting in the first transmission belt 13 being unable to drive the first transmission wheel 12 and the third transmission wheel 15, causing the device to lose the effect of crushing the plants.

[0055] Further, the sealed door 24 on the extraction box 1 is opened, and the plants to be extracted are placed in the extraction box 1. The plants fall from the feed plate 32 onto the crushing roller 25, and the first motor 22 is started. The first motor 22 drives the first rotating rod 28 connected thereto, and the first rotating rod 28 connected to the first motor 22 drives the fourth transmission wheel 30 to rotate, and the fourth transmission wheel 30 drives the second transmission belt 31, and the second transmission belt 31 drives another fourth transmission wheel 30 to rotate, thereby driving the first rotating rod 28 not connected to the first motor 22 to rotate, so that the two first rotating rods 28 rotate synchronously, and the first rotating rod 28 drives the horizontal block 29 to move through the thread, and the horizontal block 29 drives the connecting transverse plate 27 to move, and the connecting transverse plate 27 drives the combing block 26 to move, and by controlling the first motor 22, the combing block 26 is caused to move in the crushing The combing block 26 moves back and forth above the crushing roller 25; during the movement of the combing block 26, the combing block 26 drives the plants that have not been crushed on the crushing roller 25, thereby dispersing the uncrushed plants at various positions on the crushing roller 25, preventing the plants from falling onto the crushing roller 25. Due to the local accumulation of plant materials on the crushing roller 25, the efficiency of crushing the plants is reduced, and personal injuries caused by manual dispersion of plants on the crushing roller 25 are prevented, thereby reducing labor costs and improving the safety of the device; the combing block 26 drives the uncrushed plants on the crushing roller 25, and to a certain extent avoids the problem of the crushing roller 25 being stuck due to factors such as the accumulation of plant materials and too many plants, thereby reducing downtime, eliminating the need for personnel to watch at all times, improving the efficiency of plant essential oil extraction, and avoiding the subsequent process of dispersing plant materials due to the jamming of the crushing roller 25.

The first transmission belt 13 drives the first transmission wheel 12, the first transmission shaft 11, and the crushing roller 25 to rotate, and the crushing roller 25 crushes the plants; at the same time, the second rotating rod 18 drives the worm 39 to rotate, the worm 39 drives the worm wheel 36 to rotate, the worm wheel 36 drives the central shaft 35 to rotate, and the central shaft 35 drives the rotating plate 38 and the rotating disc 34 to rotate. The plants crushed by the crushing roller 25 gradually fall onto the rotating disc 34. As the rotating disc 34 rotates , the crushed plant material is distributed throughout the rotating disc 34, and as the rotating disc 34 drives the plant material to rotate, the plant material gradually falls onto the filter plate 37 through the through slot 43, and the plant material falling from the rotating disc 34 is initially dispersed on the filter plate 37. As the rotating plate 38 rotates, the rotating plate 38 drives the plant material on the filter plate 37, thereby further dispersing the plant material; the rotating disc 34 preliminarily disperses the plant material, thereby preventing the plant material from accumulating on the filter plate 37, causing the rotating plate 38 to fail to disperse the plant material in time, causing the rotating plate 38 to get stuck and lose its dispersing effect, and avoiding the crushing roller 25 from being unable to rotate due to the stuck rotating plate 38, thereby affecting the crushing process;

[0059] The plant material is evenly dispersed on the filter plate 37 to ensure the uniformity of the dispersion of the plant material, so that during the extraction and purification process, the plant material and the steam can be fully contacted, so that the steam can effectively penetrate the plant material and fully contact the essential oil components inside the plant material, so that the steam and the essential oil can pass through the essential oil, thereby improving the extraction efficiency and avoiding the problem that the plant material only falls to the position below the gap between the two crushing rollers 25 due to the crushing of the plant by the crushing roller 25, causing the accumulation of plant material, leading to local overheating or uneven extraction.

[0060] See also Figure 3 and Figure 5 , the present invention provides an embodiment: an extraction and purification device for the production of plant essential oils, wherein a worm 39 is provided on the second rotating rod 18, and a worm gear 36 is meshedly installed on the side wall of the worm 39, and the worm gear 36 is fixedly installed on the outer wall of the central shaft 35, and the central shaft 35 is movably installed on the inner wall of the extraction box 1, and a rotating plate 38 is fixedly connected to the outer wall of the central shaft 35 at equal intervals, and a rotating disc 34 is fixedly connected to the top of the outer wall of the central shaft 35. The rotating disc 34 is located below the crushing roller 25, and through slots 43 are equidistantly opened on the rotating disc 34; the inner wall of the extraction box 1 is fixedly connected to a circular hole plate 33, and a compression spring 42 is fixedly connected to the inside of the circular hole plate 33 at equal intervals. A collision body 41 is fixedly connected to the side wall of the compression spring 42, and the outer wall of the collision body 41 is movably covered with a circular hole plate 33. The collision body 41 contacts the rotating disc 34, and the outer wall of the rotating disc 34 is fixedly connected to a hemisphere 40.

[0061] Furthermore, the crushed plants gradually fall onto the rotating disc 34. As the central shaft 35 drives the rotating disc 34 to rotate, the plant materials are distributed all over the rotating disc 34. As the rotating disc 34 rotates, the plant materials pass through the through slots 43 on the rotating disc 34 and fall below the extraction box 1. The central shaft 35 drives the rotating plate 38 to rotate, and the rotating plate 38 further disperses the plant materials. At the same time, the rotating disc 34 drives the hemisphere 40. During the circular motion of the hemisphere 40, the hemisphere 40 0 will gradually approach the collision body 41 and contact with the collision body 41. When the hemispherical body 40 contacts the collision body 41, the hemispherical body 40 drives the collision body 41 to squeeze the compression spring 42. When the hemispherical body 40 is no longer in contact with the collision body 41, the compression spring 42 returns to its original state from the compressed state. The compression spring 42 drives the collision body 41 to hit the rotating disc 34, causing the rotating disc 34 to vibrate, thereby accelerating the falling of the plant material, preventing the plant material from accumulating on the rotating disc 34, and preventing the plant material from clogging the through groove 43;

[0062] In addition, the hemispheres 40 on the rotating disk 34 are not arranged at equal intervals, so that when one of the hemispheres 40 contacts the collision body 41 arranged at equal intervals in the circular hole plate 33, there are multiple or all of the remaining hemispheres 40 that are not in contact with the collision body 41. Therefore, when the collision body 41 hits the rotating disk 34, there will be no collision bodies 41 in symmetrical positions hitting the rotating disk 34 at the same time, resulting in the forces exerted on the rotating disk 34 canceling each other out, causing the vibration amplitude of the rotating disk 34 to be too small or unable to vibrate.

[0063] See also Figure 2 An embodiment of the present invention provides: an extraction and purification device for producing plant essential oils, comprising an extraction box 1 and a spacing adjustment component, wherein the extraction box 1 is provided with crushing rollers 25, and the spacing adjustment component is used to adjust the distance between the crushing rollers 25; the outer wall of the extraction box 1 is symmetrically fixedly connected to a limiting frame 3, the limiting frame 3 is in contact with a guide block 8, and the outer wall of the extraction box 1 is symmetrically provided with displacement grooves 6, which are movably sleeved on the outer wall of the displacement block 5.

[0064] Furthermore, in the process of adjusting the distance between the crushing rollers 25, the guide block 8 moves in the limit frame 3. The limit frame 3 ensures that the guide block 8 is level when moving, avoiding the offset of the guide block 8. The limit frame 3 also provides protection for the guide block 8 to avoid damage to the guide block 8; when the displacement block 5 moves in the displacement groove 6, the displacement groove 6 limits the moving range of the displacement block 5, avoiding the two displacement blocks 5 from getting too close due to operational errors, causing the two crushing rollers 25 to collide with each other and cause damage to the crushing rollers 25; avoiding the two displacement blocks 5 from being too far away from each other, causing the two crushing rollers 25 to be too far away from each other, causing the crushing rollers 25 to lose their crushing function.

[0065] Working principle: The driving motor 20 drives the rotating gear 21, the movable tooth plate 9, the guide block 8, the connecting block 10, and the displacement block 5. The displacement block 5 drives the first transmission shaft 11 and the crushing rollers 25 to move and adjust the distance between the crushing rollers 25. The tension spring 45 drives the adjusting block 44, the connecting shaft 7, and the second transmission wheel 14. The second transmission wheel 14 squeezes the first transmission belt 13 and adjusts the tension of the first transmission belt 13.

[0066] The second motor 23 drives the second rotating rod 18, the second rotating rod 18 drives the second gear 19, the first gear 16, the connecting rod 17, and the third transmission wheel 15, the third transmission wheel 15 drives the first transmission belt 13, the first transmission wheel 12, the first transmission shaft 11, and the crushing roller 25, and the crushing roller 25 crushes the plants;

[0067] The first motor 22 drives the first rotating rod 28, the horizontal block 29, the connecting cross plate 27, and the combing block 26. The combing block 26 disperses the plants on the crushing roller 25. The second rotating rod 18 drives the worm 39, the worm gear 36, the central shaft 35, the rotating plate 38, and the rotating disc 34. The plants fall from the through groove 43 onto the filter plate 37. The rotating plate 38 disperses the material on the filter plate 37.
