[0021] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] This invention provides an automatic feeding device.

[0024] First embodiment: Please refer to the following: Figures 1 to 3 In this invention, the automatic feeding device includes: Material bin 1; The vertical feeding assembly 2 includes a vertical transmission pipe 21, a spiral conveying rod 22, and a first driving component 23. The vertical transmission pipe 21 is fixedly installed on the material box 1. The bottom of the vertical transmission pipe 21 has an inlet 210 and the top of the vertical transmission pipe 21 has an outlet 211. The spiral conveying rod 22 is rotatably installed inside the vertical transmission pipe 21. The fixing part of the first driving component 23 is fixedly installed at the bottom of the vertical transmission pipe 21. The driving shaft of the first driving component 23 passes through the vertical transmission pipe 21 and is fixedly connected to the bottom end of the spiral conveying rod 22. The connecting component 3 includes a sleeve 31, a conveying pipe 32, and an elastic support 33. The sleeve 31 is slidably mounted on the vertical transmission pipe 21. The input end of the conveying pipe 32 is fixed on the sleeve 31. The fixing part of the elastic support 33 is fixed on the vertical transmission pipe 21. The telescopic part of the elastic support 33 is fixedly connected to the sleeve 31. Vibration assembly 4 includes a first bevel gear 41, a first rotating shaft 42, a second bevel gear 43, and a cam 44. The first bevel gear 41 is fixed to the top end of the spiral conveying rod 22. The first rotating shaft 42 passes through the vertical transmission tube 21 and is rotatably connected. The second bevel gear 43 is fixed to one end of the first rotating shaft 42 and meshes with the first bevel gear 41. The cam 44 is fixed to the other end of the first rotating shaft 42, and the surface of the cam 44 abuts against the top of the sleeve 31. The input end of the conveying pipe 32 is connected to the discharge port 211 through the sleeve 31.

[0025] In this embodiment, the first driving component 23 is a motor structure, which facilitates direct driving of the spiral conveying rod 22 to achieve stable rotational adjustment within the vertical transmission pipe 21.

[0026] In this embodiment, the feed inlet 210 is aligned with the material storage area of ​​the material box 1. The material box 1 is filled with medicinal materials that need to be transported in advance or continuously, so as to facilitate the subsequent transfer and feeding of medicinal materials.

[0027] The elastic support 33 is a spring-supported tubular structure used to provide an upward elastic force to the sleeve 31, so that the top of the sleeve 31 can maintain contact with the cam 44.

[0028] The vibration principle of the conveying pipe 32: See also Figure 4 (a) to Figure 4 (b) to Figure 4 (c) and Figure 5(a) to Figure 5 (b) to Figure 5 In (c), when the cam 44 rotates clockwise, the protrusion of the cam 44 gradually separates from the sleeve 31, and the elastic support 33 adaptively moves upward under the elastic action, while maintaining the abutment between the sleeve 31 and the cam 44, until the top of the sleeve 31 completely disengages from the protrusion of the cam 44, and both the sleeve 31 and the conveying pipe 32 remain in the upward state; Similarly, as the cam 44 continues to rotate, the protrusion of the cam 44 gradually contacts the sleeve 31. After contact, the protrusion of the cam 44 abuts against the sleeve 31 and moves downward. The elastic support 33 is compressed and contracted under the pressure of the sleeve 31 until the protrusion of the cam 44 completely abuts against the sleeve 31. The sleeve 31 and the conveying pipe 32 are both maintained in the downward state. In this way, as the cam 44 rotates continuously, it drives the conveying pipe 32 to vibrate adaptively up and down, providing vibration support for the stable discharge of materials entering the conveying pipe 32.

[0029] The vertical transmission pipe 21 is connected to the material box 1 by vertical installation, which reduces the floor space occupied by the equipment during installation and use, and reduces the space required for movement and adjustment. When the first driving member 23 drives the spiral conveying rod 22 to rotate, the spiral conveying rod 22 carries the material entering the range of the vertical transmission pipe 21 upward. At the same time, the spiral conveying rod 22 drives the first bevel gear 41 to rotate, the first bevel gear 41 drives the second bevel gear 43 to rotate, and the first rotating shaft 42 drives the cam 44 to rotate synchronously, so that the cam 44 rotates and squeezes the sleeve 31. Under the elastic support of the elastic support member 33, the sleeve 31 drives the conveying pipe 32 to vibrate up and down, so as to facilitate the vibration discharge of the conveying pipe 32, so that the material enters the conveying pipe 32 and is discharged stably under the action of vibration.

[0030] In this embodiment, the vertical transmission pipe 21 can be used for feeding materials into a separate receiving device, enabling one-to-one material conveying and feeding.

[0031] In this embodiment, the bottom of the material box 1 is inclined, and the inclined surface faces the position of the feed inlet 210.

[0032] The inclined structure inside the material bin 1 allows the material entering the material bin 1 to be stably transported toward the feed inlet 210. The material can easily pass through the feed inlet 210 and enter the range of the vertical transmission pipe 21 through the inclined structure.

[0033] In this embodiment, the bottom of the material box 1 is equipped with casters 11.

[0034] By providing the movable wheels 11 at the bottom of the material box 1, it is convenient to move and adjust the material box 1 and the vertical feeding assembly 2 as a whole.

[0035] In an optional embodiment of this example, the moving wheel 11 adopts a self-braking wheel structure, which facilitates the movement of the equipment and can also brake and lock as needed.

[0036] The working principle of the automatic feeding device provided in this embodiment is as follows: A1, Equipment docking, move the material box 1, the material box 1 drives the vertical feeding component 2 to move towards the receiving device until the output end of the conveying pipe 32 is aligned with the input end of the receiving device, so that the material output by the conveying pipe 32 can enter the interior of the receiving device through the input end of the receiving device when the equipment is running. A2, Material addition: The material to be transported and fed is put into the inside of the material box 1, and the material enters the inside of the vertical transmission pipe 21 through the feed port 210; A3, material conveying and feeding: start the first driving component 23, the first driving component 23 drives the spiral conveying rod 22 to rotate, the spiral conveying rod 22 rotates and drives the material in the vertical transmission pipe 21 to be vertically conveyed upward until the material enters the interior of the conveying pipe 32 through the discharge port 211. When the spiral conveyor rod 22 rotates, it also drives the first bevel gear 41 to rotate. The first bevel gear 41 drives the second bevel gear 43 to rotate. The second bevel gear 43 drives the first rotating shaft 42 to rotate. The first rotating shaft 42 drives the cam 44 to rotate. When the cam 44 rotates continuously, it drives the sleeve 31 to vibrate up and down. The sleeve 31 drives the conveying pipe 32 to vibrate up and down, so that the material entering the conveying pipe 32 vibrates and discharges, so that the material can stably enter the interior of the receiving equipment.

[0037] Second embodiment: Please refer to the following: Figures 6 to 7 Based on the automatic feeding device provided in the first embodiment of the present invention, the second embodiment of the present invention proposes another automatic feeding device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0038] Specifically, the automatic feeding device provided in the second embodiment of the present invention differs in that the automatic feeding device further includes: The horizontal feeding assembly 5 includes a feeding pipe 51, a second drive component 52, a belt conveyor 53, multiple isolation plates 54, and a solenoid valve 55. The top of the feeding pipe 51 is hoisted onto the top beam by a hoisting assembly 6. A receiving pipe 511 is provided at the top of the feeding pipe 51, and a discharge pipe 512 is provided at the bottom of the feeding pipe 51. The second drive component 52 is installed on the feeding pipe 51. The belt conveyor 53 is rotatably installed inside the feeding pipe 51. Multiple isolation plates 54 are evenly fixed on the conveying surface of the belt conveyor 53. The solenoid valve 55 is installed on the discharge pipe 512. The drive shaft of the second drive member 52 passes through the feed pipe 51 and is fixedly connected to the shaft end of the belt conveyor 53. At least five discharge pipes 512 are provided, and each discharge pipe 512 corresponds to a solenoid valve 55.

[0039] In this embodiment, the output end of the discharge pipe 512 is aligned with the input end of the receiving device. The number of receiving devices is equal to that of the discharge pipe 512, and they are set in a one-to-one correspondence. This allows the feeding requirements of multiple receiving devices to be met by using one vertical feeding component 2 and one horizontal feeding component 5.

[0040] In this embodiment, the solenoid valve 55 is a solenoid butterfly valve, used to control the opening and closing of the discharge pipe 512; When the discharge pipe 512 is in the closed state, the material conveyed in the feeding pipe 51 will not be discharged downward through the discharge pipe 512; When the discharge pipe 512 is in the open state, the material conveyed in the feeding pipe 51 can be discharged downward through the discharge pipe 512.

[0041] In this embodiment, the receiving pipe 511 is connected to the feeding pipe 51, which facilitates the delivery of materials received by the receiving pipe 511 into the feeding pipe 51. The discharge pipe 512 is connected to the feeding pipe 51, so that the material conveyed by the belt conveyor 53 can be discharged downward through the open discharge pipe 512.

[0042] When facing the need for feeding multiple devices, by connecting the vertical feeding component 2 to the horizontal feeding component 5, feeding can be achieved at different feeding points without moving the vertical feeding component 2, reducing the space required for equipment operation and eliminating the need to frequently move the vertical feeding component 2.

[0043] In an optional embodiment of this example, the second driving member 52 may be a motor structure, used to directly drive the rotation adjustment of the belt conveyor 53, so as to facilitate the individual conveying control of the material in the feeding pipe 51.

[0044] Specifically, the belt conveyor 53 includes two rollers and a conveyor belt. The two rollers are rotatably mounted inside the feeding pipe 51, and the conveyor belt drives the two rollers. Multiple isolation plates 54 are evenly fixed on the conveyor belt. The drive shaft of the second drive member 52 is fixedly connected to any one of the rollers. The second drive member 52 facilitates the rotation of the rollers, which in turn drives the conveyor belt to rotate and transport materials. The conveyor belt drives the isolation plates 54 to rotate and transport materials around the feeding pipe 51, ensuring that materials falling on the conveyor belt are stably transported within the feeding pipe 51.

[0045] Preferably, an auxiliary support plate 56 is fixedly installed inside the feeding pipe 51, and the top of the auxiliary support plate 56 is supported on the surface of the conveyor belt. This ensures the stability of the material being conveyed by the conveyor belt.

[0046] Please refer to it again. Figure 6 The hoisting assembly 6 includes a hoisting plate 61 and a hoisting rod 62. The top of the hoisting plate 61 is fixed to the top beam, and the two ends of the hoisting rod 62 are respectively fixedly connected to the hoisting plate 61 and the feeding pipe 51.

[0047] The feeding pipe 51 can be easily hoisted and installed on the top beam (the roof beam inside the building) using the hoisting plate 61, which facilitates the hoisting and operation of the feeding pipe 51 during use, so as to accurately transfer and feed materials from the top of the receiving equipment.

[0048] Please refer to the following: Figure 6 and Figure 8 The automatic feeding device further includes a docking assembly 7, which includes a limiting cover 71, a telescopic member 72, a locking block 73, and a docking plate 74. The limiting cover 71 is fixed on the feeding pipe 51, and a shrinkage groove 711 is provided inside the limiting cover 71. The telescopic member 72 is fixed on the limiting cover 71, and the telescopic part of the telescopic member 72 passes through the limiting cover 71 and is fixedly connected to the top of the locking block 73. One end of the docking plate 74 is fixed on the vertical transmission pipe 21, and a locking groove 741 is provided on the top of the docking plate 74. When the docking plate 74 is fully inserted into the limiting cover 71, the locking block 73 is inserted into the range of the locking groove 741.

[0049] In this embodiment, when the docking plate 74 is horizontally inserted into the range of the limiting cover 71, the locking groove 741 and the shrinking groove 711 are aligned vertically, so that the locking block 73 can move down and be inserted into the range of the locking groove 741.

[0050] While the conveying pipe 32 and the receiving pipe 511 are docking, the docking plate 74 can be inserted into the limiting cover 71. Then, the telescopic member 72 controls the locking block 73 to move down and insert into the locking groove 741, so that the docking plate 74 and the limiting cover 71 are locked together. This is used to increase the stability of the connection between the vertical transmission pipe 21 and the feeding pipe 51 and to prevent the connection from loosening and separating during the operation of the equipment.

[0051] In an optional embodiment of this invention, the telescopic member 72 can be any one of an electric telescopic cylinder, a hydraulic telescopic cylinder, or a telescopic pneumatic cylinder. This allows for direct driving of the locking block 73 via the telescopic member 72, facilitating direct control of the locking or unlocking of the docking plate 74 and the limiting cover 71.

[0052] In another optional embodiment of this example, the telescopic member 72 can be a spring support tube, the bottom of the locking block 73 is provided with a first inclined surface, and the end of the docking plate 74 is provided with a second inclined surface, with the first inclined surface and the second inclined surface corresponding to each other.

[0053] To facilitate the insertion of the docking plate 74 into the range of the limiting cover 71, the telescopic member 72, under elastic action, adaptively controls the locking block 73 to be compressed and retracted before being inserted into the range of the locking groove 741, thereby achieving automatic locking and limiting after the docking plate 74 is connected to the limiting cover 71.

[0054] Specifically, during the process of inserting the docking plate 74 into the limiting cover 71, the first inclined surface first contacts the second inclined surface. When the docking plate 74 continues to be inserted, the locking block 73 adaptively retracts upward under the squeezing action, providing clearance for the docking plate 74 to be stably inserted into the limiting cover 71. When the docking plate 74 is fully inserted into the limiting cover 71, the locking groove 741 and the shrinking groove 711 are aligned vertically. Under the elastic action of the telescopic member 72, the locking block 73 is adaptively inserted into the range of the locking groove 741 to achieve automatic locking after the docking plate 74 is inserted into the limiting cover 71.

[0055] The working principle of the automatic feeding device provided in this embodiment is as follows: B1, Equipment docking: First, align the output end of the discharge pipe 512 with the input end of the corresponding receiving device, then move the material box 1. The material box 1 drives the vertical feeding component 2 to move towards the horizontal feeding component 5 until the output end of the conveying pipe 32 is aligned vertically with the input end of the receiving pipe 511. B2, material is conveyed upwards, the first driving component 23 is activated, the first driving component 23 drives the spiral conveyor 22 to rotate, and the spiral conveyor 22 conveys the material passing through the feed port 210 upwards; After being conveyed upwards, the material enters the interior of the conveying pipe 32 through the discharge port 211. While the conveying pipe 32 vibrates, it steadily conveys the material into the receiving pipe 511. The receiving pipe 511 then conveys the material to the range of the feeding pipe 51. B3, material horizontal transmission, start the second drive unit 52, the second drive unit 52 drives the belt conveyor 53 to rotate, the belt conveyor 53 rotates and drives the isolation plate 54 to rotate and convey within the range of the feeding pipe 51, so that the material falling between two adjacent isolation plates 54 is rotated and conveyed within the range of the feeding pipe 51. B4, Material feeding: Activate the corresponding solenoid valve 55. The solenoid valve 55 controls the discharge pipe 512 to open. The discharge pipe 512 discharges the material conveyed in the feeding pipe 51 downwards, so that the material is fed into the receiving equipment through the discharge pipe 512, providing feeding support for subsequent material processing.

[0056] Third embodiment: Please refer to the following: Figure 9 and Figure 10 Based on the automatic feeding device provided in the second embodiment of the present invention, the third embodiment of the present invention proposes another automatic feeding device. The third embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the third embodiment will not affect the separate implementation of the first embodiment.

[0057] Specifically, the automatic feeding device provided in the third embodiment of the present invention differs in that the second driving member 52 includes a first gear 521, a second rotating shaft 522, a second gear 523, and a transmission member 524. The first gear 521 is fixedly disposed on the shaft end of the roller, one end of the second rotating shaft 522 is rotatably mounted on the vertical transmission tube 21, the second gear 523 is fixedly disposed on the second rotating shaft 522, and the transmission member 524 is drivingly connected to the first rotating shaft 42 and the second rotating shaft 522. When the docking plate 74 is fully inserted into the limiting cover 71, the second gear 523 engages with the first gear 521.

[0058] While the output end of the conveying pipe 32 is connected to the receiving pipe 511, the second gear 523 automatically engages with the first gear 521. This allows the first driving component 23 to not only drive the spiral conveyor rod 22 to vertically feed materials, but also to simultaneously drive the conveyor pipe 32 to vibrate and discharge materials, and simultaneously drive the belt conveyor 53 to horizontally convey and feed materials.

[0059] In an optional embodiment, the transmission component 524 may include two pulleys and a belt. The belt drives the two pulleys, one pulley is fixedly connected to the first rotating shaft 42, and the other pulley is fixedly connected to the second rotating shaft 522. This allows the second rotating shaft 522 to be rotated and adjusted synchronously through the transmission component 524 while the first rotating shaft 42 is rotating.

[0060] In another optional embodiment, the transmission component 524 may include two sprockets and a chain.

[0063] The present invention also provides a method for preparing Ophiopogon japonicus extract.

[0064] Please see Figure 11 The preparation method of the Ophiopogon japonicus extract specifically includes the following steps: Step S1: Use a herbal coarse crushing device to coarsely crush the Ophiopogon japonicus herbal material to obtain coarse crushed material; Step S2: The coarse crushed material is conveyed and fed into the soaking equipment using the automatic feeding device, and soaked in water with 4 times the amount of medicinal material for 3 hours to obtain the soaking solution; Step S3: Load the soaking solution into a percolation column, percolate with 8 times the amount of water as the medicinal material, and collect the percolate; In step S4, the percolate is adsorbed by D101 macroporous resin. After loading the sample, it is eluted with 4BV water and 4BV 60% ethanol in sequence. The column buffer and the washing solution are combined and separated by passing through a ceramic membrane and a 3000D ultrafiltration membrane in sequence to obtain the small molecule functional sugar fraction of Ophiopogon japonicus. This fraction is decolorized with activated carbon, and then concentrated and dried to obtain the decolorized small molecule functional sugar fraction. Step S5: The macroporous resin 60% alcohol eluent is concentrated and dried to obtain Ophiopogon japonicus saponins and flavonoid fractions; Step S6: Then, the decolorized small molecule functional sugar fraction is combined with the saponin and flavonoid fractions to obtain the target product.

[0065] In this embodiment: Ophiopogon japonicus is extracted using water percolation, resulting in a clear percolate that facilitates subsequent processing. Macroporous resin technology and membrane separation technology are then employed to effectively separate the small-molecule functional sugar fraction from the saponin and flavonoid fractions. A 3000D ultrafiltration membrane is used for further separation to obtain specific small-molecule functional sugars. After decolorization, the product has a lighter color, making it easier to add to cosmetics. The small-molecule functional sugars, combined with saponins and flavonoids in specific proportions, contain small-molecule sugars, amino acids, saponins, and flavonoids, with total sugar content of 60.7%, protein content of 3.1%, ruscosaponin content of 0.2%, and total flavonoid content of 1.5%. This combination of small-molecule functional sugars, saponins, and flavonoids inhibits inflammation through the JAK-STAT pathway and can be used for dermatitis and eczema.

[0066] The final product is simple and practical in terms of process, has a light color, contains small molecule functional sugars of Ophiopogon japonicus with specific molecular segments, and contains some saponins and flavonoids. It can be dissolved in cosmetic systems, which solves the problems of process and product quality in the simultaneous utilization of active small molecule functional sugars of Ophiopogon japonicus with saponins and flavonoids. It can inhibit inflammation through the JAK-STAT pathway and is used for dermatitis and eczema.

[0067] Specifically, 800g of Ophiopogon japonicus (Mai Dong) was coarsely crushed and soaked in 4 times the amount of water for 3 hours. The mixture was then loaded into a percolation column and percolated with 8 times the amount of water. The percolate was collected and adsorbed onto 1.5 kg of D101 macroporous resin. After loading, the resin was eluted sequentially with 4 BV of water and 4 BV of 60% ethanol. The percolate and washings were combined and sequentially separated using a ceramic membrane and a 3000D ultrafiltration membrane. The ultrafiltration permeate was concentrated to a specific gravity of 1.15 ± 0.02 (55~60℃) under a vacuum of -0.06~-0.08 MPa at 55~60℃. 15g of activated carbon was added and decolorized at 60℃ for 3 hours. The filtrate was then obtained and vacuum-dried at a vacuum of -0.07~-0.1 MPa at 55~60℃ for 3~5 hours. The decolorized small-molecule functional sugars were obtained by pulverization; the 60% alcohol eluent from the macroporous resin was concentrated to a specific gravity of 1.15±0.02 (55~60℃), the vacuum degree was -0.06~-0.08 MPa, the temperature was 55~60℃, and then vacuum dried at a vacuum degree of -0.07~-0.1 MPa, a drying temperature of 55~60℃, and a drying time of 3~5 h. After drying, the small-molecule functional sugars were pulverized and dried to obtain the saponins and flavonoids of Ophiopogon japonicus; finally, the decolorized small-molecule functional sugars were combined with the saponins and flavonoids in a ratio of (5:1-8:1) to obtain a composition of small-molecule functional sugars, saponins, and flavonoids.
