Description

Technical Field

[0001] The invention belongs to the technical field of sleeping patch processing, and in particular relates to a plant essential oil filling device for sleeping patches. Background Art

[0002] Sleeping patch is a product that helps sleep. It usually works by absorbing substances containing sleep-inducing ingredients through the skin. The principle is to use the permeability of the skin to allow the active ingredients (such as linalool and lavender alcohol in plant essential oils) to enter the blood circulation through the stratum corneum, thereby affecting the nervous system, soothing the nerves and relaxing the body and mind, thereby helping users to fall asleep more easily. The sleeping patch is provided with a carrier layer: This is the basic part of the sleeping patch, which is generally made of materials such as non-woven fabrics, spunlace fabrics or medical tapes. Non-woven fabrics are soft and breathable, can fit the skin well, and will not cause allergic reactions. For example, spunlace fabrics are made by spraying the fiber mesh with high-pressure fine water flow to make the fibers entangled with each other. It has a delicate texture and is more comfortable when in contact with the skin. Drug or essential oil layer: This is the core part of the sleeping patch, containing sleep-inducing ingredients such as plant essential oils and Chinese medicine extracts. Plant essential oils such as lavender essential oil and chamomile essential oil are common choices. Lavender essential oil contains a variety of sedative ingredients that can relieve anxiety. Chinese herbal medicine extracts may include ingredients such as Chinese jujube seeds and Polygala tenuifolia. Saponins and flavonoids in Chinese jujube seeds have a calming effect. In the production process of the sleep patch, plant essential oils need to be poured onto the carrier layer.

[0003] However, in the production process of existing sleeping patches, when the plant essential oil is poured onto the carrier layer, the essential oil cannot be evenly distributed on the carrier layer. If the essential oil is unevenly distributed, some skin areas may be exposed to too much essential oil when the sleeping patch is used, while some areas are exposed to too little essential oil. For example, if lavender essential oil is concentrated on one side of the sleeping patch, when it is applied to the skin, only the skin on that side can better absorb the soothing ingredients of lavender essential oil, such as linalool and linalyl acetate, which have a calming effect on the nerves. The skin on the other side cannot fully benefit from the small amount of essential oil it is exposed to, thus affecting the sleep-aiding effect of the entire sleeping patch; uneven distribution may cause local over-stimulation of the skin.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] The following describes in detail the technical solution of a plant essential oil filling device for a sleep patch according to various embodiments of the present invention in conjunction with the accompanying drawings.

[0031] Reference Figures 1 to 8 As shown, an embodiment of the present invention provides a plant essential oil filling device for a sleep patch, comprising a mounting seat 1; a mounting groove 11 is provided at the bottom of the mounting seat 1; a filling moving structure 2, which is arranged at the top inner side of the mounting seat 1; two carrier filling structures 3 are provided on one side of the filling moving structure 2 for filling plant essential oils onto the carriers; an essential oil uniformly moving structure 4 for uniformly distributing the plant essential oils is provided on the other side of the filling moving structure 2; a carrier pulling structure 5, which is arranged in the mounting groove 11, and both ends of the carrier pulling structure 5 extend to the outside of both ends of the mounting seat 1; a carrier fixing structure 6, which is arranged on the carrier pulling structure 5 to fix the position of the carrier.

[0032] Specifically, the filling and pasting moving structure 2 includes an intermediate electric slide 21, a transverse electric slide 22, a moving block 23, an upper mounting block 24, a lower mounting block 25 and a moving cylinder 26. The intermediate electric slide 21 is located in the middle position of the inner top of the mounting seat 1. Both ends of the intermediate electric slide 21 are provided with slides 27. The moving block 23 slides with the two slides 27 and is connected to the moving end of the intermediate electric slide 21; the transverse electric slide 22 is installed at the bottom of the moving block 23, the upper mounting block 24 is connected to the bottom of the transverse electric slide 22, the moving cylinder 26 is arranged in the upper mounting seat 1, and the lower mounting block 25 is connected to the telescopic end of the moving cylinder 26.

[0033] The plant essential oil filling and pasting device of the present invention, through its carefully designed filling and pasting moving structure 2, realizes precise positioning capability, smooth moving performance, flexible height adjustment, structural stability and durability, and high degree of automation, which significantly improves the efficiency and quality of plant essential oil filling and pasting, and provides reliable technical guarantee for the production of sleep patches. Specifically, the middle electric slide 21 is located in the middle position of the inner top of the mounting seat 1. As the main moving platform, it forms a two-axis linkage system with the transverse electric slide 22, and is installed at the bottom of the moving block 23, realizing precise movement in the X-axis and Y-axis directions, so that the filling and pasting head can be quickly and accurately positioned to any position of the carrier, ensuring that the plant essential oil can be accurately filled and pasted to the predetermined position, improving the accuracy and efficiency of filling and pasting; the slide 27 is arranged at both ends of the middle electric slide 21, and slides with the moving block 23, reducing friction and resistance during movement, ensuring the stability of the moving block 23 during sliding, avoiding the problem of inaccurate filling and pasting caused by mechanical vibration or offset, thereby ensuring the uniform distribution of the essential oil; the moving cylinder 26 is arranged in the upper mounting seat 1, and the lower mounting block 25 is in contact with the moving block 23. The telescopic end connection of the dynamic cylinder 26 provides flexibility in height adjustment, and the height of the filling and pasting head can be quickly adjusted to adapt to carriers of different thicknesses and types, thereby enhancing the versatility and adaptability of the device; the upper mounting block 24 is connected to the bottom of the transverse electric slide 22, providing additional support and stability, and forming a solid support structure with the lower mounting block 25, thereby improving the stability and durability of the entire filling and pasting mobile structure 2, reducing vibration and wear of the equipment during operation, extending the service life of the equipment, and reducing maintenance costs; the automated design of the filling and pasting mobile structure 2 achieves precise control through a PLC controller, thereby reducing the need for manual intervention, and automated operation not only improves production efficiency, but also ensures the stability and consistency of product quality, thereby reducing human errors in the production process.

[0034] When the plant oil is poured onto the carrier, the middle electric slide 21 can drive the moving block 23 to move forward and backward on the two slideways 27, so as to drive the positions of the two automatic pouring heads 32 and the two rotating brush heads 45 to move forward and backward, and to pour and paste different front and rear positions on the carrier, and subsequently to evenly distribute the plant essential oil on the carrier. The transverse electric cylinder can drive the two automatic pouring heads 32 and the two rotating brush heads 45 to move left and right, and to pour and paste different left and right positions on the carrier, and subsequently to evenly distribute the plant essential oil on the carrier; the moving cylinder 26 can move the position of the lower mounting block 25 downward, and move the positions of the two automatic pouring heads 32 to the top of the carrier;

[0035] The filling and pasting moving structure 2 can fully realize the filling and pasting work when the carrier is filled with plant essential oil, so that each sleeping patch on the carrier is filled and pasted.

[0036] Specifically, each of the carrier filling structures 3 includes a mounting plate 31 and an automatic filling head 32 . The mounting plate 31 is horizontally arranged on the side wall of the lower mounting block 25 , and the automatic filling head 32 is vertically arranged on the mounting plate 31 .

[0037] The automatic filling head 32 belongs to the prior art. The automatic filling head 32 is connected to an external pipeline for conveying plant essential oil. When filling and pasting, the automatic filling head 32 automatically fills the plant essential oil into the middle position of the carrier.

[0038] Specifically, there are two structures 4 for evenly moving the essential oil, which are symmetrically arranged on the lower mounting block 25 and correspond to the two automatic filling heads 32; each of the structures 4 for evenly moving the essential oil includes a connecting block 41, a driving electric cylinder 42, a rotating round cover 43, an eccentric wheel 44, a rotating brush head 45 and a driving motor 46, the connecting block 41 is located on the side wall of the lower mounting block 25, the driving electric cylinder 42 is arranged on the top of the connecting block 41, a mounting shaft 47 is arranged on the telescopic end of the driving electric cylinder 42, the driving motor 46 is located in the mounting shaft 47, the rotating round cover 43 is horizontally connected to the bottom of the mounting shaft 47, the eccentric wheel 44 is eccentrically connected to the main shaft of the driving motor 46, and the rotating brush head 45 is located at the bottom of the eccentric wheel 44; the position of the rotating brush head 45 extends to the outside of the rotating round cover 43.

[0039] The essential oil uniform moving structure 4 in the plant essential oil filling and applying device of the present invention realizes the efficient uniformity of essential oil filling and applying through its unique symmetrical setting and component matching. Two essential oil uniform moving structures 4 are symmetrically arranged on the lower mounting block 25, corresponding to the two automatic filling heads 32, ensuring the simultaneous operation of both sides and improving the filling and applying efficiency. Each essential oil uniform moving structure 4 includes a connecting block 41, a driving electric cylinder 42, a rotating round cover 43, an eccentric wheel 44, a rotating brush head 45 and a driving motor 46, wherein the connecting block 41 is fixed on the side wall of the lower mounting block 25 to provide stable support for the entire structure. The driving electric cylinder 42 is arranged on the top of the connecting block 41, and the mounting shaft 47 on the telescopic end thereof is built with a driving motor 46. This design enables the driving motor 46 to directly drive the eccentric wheel 44 to achieve precise control. The rotating round cover 43 is horizontally connected to the bottom of the mounting shaft 47, which forms protection while also guiding the movement of the rotating brush head 45. The eccentric wheel 44 is eccentrically connected to the main shaft of the driving motor 46, driving the rotating brush head 45 to make eccentric movement, ensuring the uniform distribution of the essential oil during the filling process. The position of the rotating brush head 45 extends to the outside of the rotating circular cover 43, so that the essential oil can be evenly applied to the edge of the carrier, avoiding the problem of uneven filling. This ingenious design not only improves the uniformity and consistency of the essential oil filling, but also enhances the stability and durability of the device, reduces maintenance costs, and provides a strong guarantee for the high-quality production of sleep patches.

[0040] After the plant-soaked oil is poured onto the paper carrier through the automatic filling head 32, the electric cylinder 42 is driven to drive the rotating circular cover 43 to move downward, and the rotating brush head 45 is moved to the top of the plant essential oil. Thereafter, the driving motor 46 is driven to drive the eccentric wheel 44 to rotate in the rotating circular cover 43, thereby driving the rotating brush head 45 to rotate, and the plant essential oil is evenly distributed at each sleeping patch position on the carrier. The even distribution can ensure that the ingredients in the plant essential oil are absorbed in a relatively balanced concentration and dosage when in contact with the skin, and continuously and stably produce a soothing and calming effect on the nervous system, thereby better helping to relax the body and mind and promote sleep; the evenly distributed essential oil can evaporate more comprehensively and stimulate the olfactory nerves during use. When the user breathes, the evenly distributed aroma can enter the nasal cavity more fully, and be transmitted to the olfactory center of the brain through the olfactory receptors, thereby affecting the emotions and nervous system, strengthening the induction effect of essential oils on sleep, and making it easier for people to enter a relaxed sleep state; if the essential oil is too concentrated in a local area of ​​the sleep patch, it may cause the skin in that area to come into contact with too high a concentration of essential oil, thereby increasing the chance of skin allergies. Even distribution can keep the contact concentration of essential oils with the skin within a relatively safe range, reducing the possibility of allergic reactions such as itching, redness and swelling caused by high-concentration stimulation; even distribution helps control the body's absorption speed and amount of essential oils, avoiding discomfort reactions such as dizziness and nausea caused by excessive amount of local essential oils and large amounts of absorption into the human body in a short period of time, ensuring the safety of the use process.

[0041] Specifically, the carrier pulling structure 5 includes a pulling motor 51, a pulling plate 52, two slide rails 53, two sliders 54, two connecting plates 55 and two pulling seats 56. The pulling motor 51 is located in the mounting groove 11, the pulling plate 52 is located on the main shaft of the pulling motor 51, the two slide rails 53 are symmetrically arranged on the side walls of the mounting groove 11, the two sliders 54 are symmetrically slidably connected to the two slide rails 53, the two ends of the connecting plate 55 are rotatably connected to the pulling plate 52 and the slider 54, and the two pulling seats 56 are respectively connected to the side walls of the two sliders 54.

[0042] Specifically, each of the pulling seats 56 is provided with a position adjustment member 7, and each of the position adjustment members 7 includes an adjustment plate 71 and an adjustment screw 72. The adjustment plate 71 is provided with two sliding rods 73. The adjustment plate 71 is slidably connected to the pulling seat 56 through the two sliding rods 73. The adjustment screw 72 is rotatably connected to the adjustment plate 71, and the adjustment screw 72 is threadedly connected to the pulling seat 56.

[0043] The carrier pulling structure 5 in the plant essential oil filling device of the present invention realizes efficient and accurate movement of the carrier through its precise design and the coordinated work of components. The pulling motor 51 is located in the mounting groove 11, driving the pulling plate 52 to rotate, thereby driving the entire structure to move. Two slide rails 53 are symmetrically arranged on the side walls of the mounting groove 11 to provide a stable track for the sliding of the slider 54. The two sliders 54 are symmetrically slidably connected to the slide rails 53, and are connected to the pulling plate 52 through the connecting plate 55, so that the rotational movement of the pulling plate 52 is converted into the linear movement of the slider 54. Two pulling seats 56 are respectively connected to the side walls of the slider 54 to provide support for the fixation and movement of the carrier. Each pulling seat 56 is provided with a position adjustment member 7, including an adjustment plate 71 and an adjustment screw 72. The adjustment plate 71 is slidably connected to the pulling seat 56 through two slide rods 73, so as to realize fine adjustment of the position. The adjusting screw 72 is rotatably connected to the adjusting plate 71 and is threadedly connected to the pulling seat 56. By rotating the adjusting screw 72, the position of the pulling seat 56 can be accurately adjusted, thereby realizing the precise positioning of the carrier during the filling and pasting process. This design not only improves the movement accuracy and stability of the carrier, but also enhances the adaptability and flexibility of the device, provides reliable support and positioning for carriers of different sizes and shapes, significantly improves the efficiency and quality of the plant essential oil filling and pasting, and provides strong technical support for the production of sleep patches.

[0044] After fixing the two ends of the carrier, the pulling motor 51 works to drive the pulling plate 52 to rotate, thereby driving the two connecting plates 55 to rotate, so that the two sliders 54 move away from each other on the two slide rails 53, thereby driving the positions of the two pulling seats 56 to move, and the position of the carrier is preliminarily straightened and tightened. After the preliminary tightening or straightening, the adjusting screw 72 can be rotated on the pulling seat 56 to drive the position of the adjusting plate 71 to adjust the position through the positions of the two slide bars 73, so that the position of the carrier is in a straightened and tightened state.

[0045] First, avoid local accumulation: when the carrier is straightened and tightened, its surface becomes flat and smooth. During the infusion of plant essential oils, the essential oils can flow and penetrate more evenly on the flat surface; for example, if the carrier, such as the non-woven material of the sleeping patch, has wrinkles, the essential oils tend to gather at the wrinkles, resulting in excessive local essential oils and insufficient essential oils in other areas; the straightened and tightened carrier can effectively prevent this situation, so that the essential oils can be distributed in the expected manner, such as evenly covering the entire carrier surface or distributed according to a specific pattern and concentration; promote penetration and absorption: the straightened and tightened carrier fibers are arranged more neatly and orderly, which is conducive to better penetration of plant essential oils into the carrier.

[0046] Second, precise control of distribution position: The tensioned carrier has a fixed position and clear boundaries, which helps to precisely control the distribution position of the essential oil. In the automated infusion equipment, the precise positioning system combined with the tensioned carrier can accurately infuse the essential oil into the designated area. For example, in the case where different types of plant essential oils need to be infused into different areas of the carrier to achieve compound effects, the tensioned carrier can ensure that each essential oil can accurately fall into the preset position, and there will be no infusion deviation due to the relaxation of the carrier; the tensioned carrier structure is tighter, which can enhance the strength of the carrier itself and reduce the risk of damage to the carrier during infusion and subsequent processing. At the same time, the tight structure also helps prevent the essential oil from leaking from the edge or weak parts of the carrier.

[0047] Specifically, there are three carrier fixing structures 6, and the three carrier fixing structures 6 are arranged at equal intervals on the side wall of the adjustment plate 71. Each of the carrier fixing structures 6 includes a fixing plate 61, a fixing screw 62, a fixing disc 63 and an ear plate 64. The fixing plate 61 and the ear plate 64 are symmetrically arranged on the side wall of the adjustment plate 71. The fixing screw 62 is threadedly connected to the ear plate 64, and the fixing disc 63 is connected to the fixing screw 62.

[0048] When fixing the position of the carrier, the carrier is placed between the fixing plate 61 and the fixing disc 63, and then the fixing screw 62 is rotated to drive the fixing disc 63 to move downward, thereby clamping and fixing the position of the carrier so that the carrier pulling structure 5 can pull the position of the carrier so that the carrier is in a straightened state.

[0049] The three carrier fixing structures 6 can be clamped and fixed at the middle position and both sides of the two ends of the carrier, so that the carrier is evenly stressed when straightened; the three fixing structures clamp the key positions of the carrier, which can effectively resist these external forces and prevent the carrier from wrinkling, bending and other deformations; different plant essential oil products may use carriers of different shapes and sizes. The design of the three fixing structures acting on the middle and both sides of the two ends respectively makes this fixing method have better adaptability. Whether it is a rectangular, circular or other irregularly shaped carrier, effective fixation can be achieved as long as the clamping range of the fixing structure is reasonably adjusted.

[0050] Specifically, the fixing plate 61 and the fixing disc 63 are provided with anti-skid patterns 65; the setting of the anti-skid patterns 65 ensures that when the fixing plate 61 and the fixing disc 63 move relative to each other to clamp the end of the carrier, when the carrier is tightened by force, it will slip out from between the fixing plate 61 and the fixing disc 63, affecting the filling and application of the plant essential oil.

[0051] A placement groove 12 is provided at the middle position of the mounting seat 1, and a lifting electric cylinder 13 is provided in the placement groove 12. A horizontally arranged lifting plate 14 is provided on the telescopic end of the lifting electric cylinder 13, and four lifting rods 15 are provided at the bottom of the lifting plate 14. A limit block 16 that slides with the lifting rod 15 is provided on the side wall of the placement groove 12.

[0052] The plant essential oil filling and pasting device of the present invention fully considers the stability of operation and the filling and pasting effect of essential oil in the detailed design. The anti-skid pattern 65 provided on the fixed plate 61 and the fixed disc 63 effectively avoids the position deviation caused by sliding in the process of clamping the end of the carrier, ensures that the carrier can be stably fixed after being tightened, and will not slide out from between the fixed plate 61 and the fixed disc 63, thereby ensuring the accuracy and consistency of the filling and pasting of plant essential oil. In addition, the placement groove 12 provided at the middle position of the mounting seat 1, the lifting electric cylinder 13 equipped inside, and the lifting plate 14 horizontally provided on the telescopic end of the lifting electric cylinder 13, together constitute a stable lifting mechanism. The four lifting rods 15 at the bottom of the lifting plate 14 slide with the limit block 16 on the side wall of the placement groove 12, which not only provides stable support, but also realizes the precise control of the lifting height. This design not only improves the adaptability of the device to carriers of different thicknesses, but also ensures the stability of the carrier and the uniform distribution of the essential oil during the filling and pasting process, further improving the production quality and efficiency of the sleep patch.

[0053] After the position of the carrier is tightened, when the plant essential oil needs to be evenly distributed, the bottom of the carrier needs to be supported and supported. At this time, the lifting electric cylinder 13 works to drive the lifting plate 14 to move on the corresponding limit blocks 16 through four lifting rods 15, and the position of the lifting plate 14 is moved to the lower position of the carrier. The bottom position of the carrier is supported to prevent the carrier from being deformed or shifted during the process of infusing or applying the essential oil; the bottom support allows the operator to control the distribution position of the essential oil more accurately.

[0054] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
