Description

Technical Field

[0001] This invention relates to the field of daylily flavonoid production technology, and in particular to a daylily flavonoid extraction raw material feeding device and method with a cleaning mechanism. Background Technology

[0002] Flavonoids are the most important class of active ingredients in daylilies. They are active substances most closely related to physiological functions such as anti-oxidation, sedation and hypnosis, and antidepression. In the extraction of flavonoids, a belt conveyor is required to feed the raw daylily.

[0003] During the conveying process, residues or dirt from daylilies will adhere to the surface of the conveyor belt, requiring regular cleaning. In existing technologies, the belt is usually cleaned manually by rinsing or brushing. Manual brushing or rinsing is physically demanding, requiring operators to hold brushes or high-pressure water guns for extended periods to clean along the length of the belt. This is especially true when the conveying distance is long or the belt width is wide, making the workload even more pronounced and prone to incomplete cleaning in certain areas. Furthermore, rinsing methods generate a large amount of wastewater containing dirt and organic residue, requiring corresponding collection and treatment facilities; otherwise, it will cause slippery ground and environmental pollution.

[0004] Therefore, it is necessary to design a feeding device and method for daylily flavonoid extraction raw material with a cleaning mechanism to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a feeding device and method for extracting flavonoids from daylilies with a cleaning mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A feeding device for extracting flavonoids from daylilies with a cleaning mechanism includes a frame. Two slide rails are provided at each end of the frame, and the four slide rails are arranged in pairs facing each other. Two first sliding plates are slidably mounted at each end of the frame, and the four first sliding plates are respectively positioned opposite the four slide rails, arranged in pairs facing each other. A rotatable transmission roller is installed between two opposing first sliding plates, and both ends of the transmission roller extend into the corresponding slide rail. The two transmission rollers are connected by a belt drive. A mounting cover is fixed to the side of one of the first sliding plates, and a first motor is mounted on the mounting cover. The output shaft of the first motor is connected to the corresponding transmission roller. A pressing component is provided on the frame. A housing is fixed on the frame, the housing stores water flow, a cleaning component is installed on the housing, and a flow guiding component and a transmission component are installed on the housing.

[0007] As a preferred embodiment of the present invention, the pressing assembly includes two vertical plates, both of which are fixed in the middle of the frame. The ends of the two vertical plates away from the frame are fixedly connected to the inner bottom surface of the housing. Each vertical plate is provided with a movable second sliding plate, and a roller is rotatably installed between the two second sliding plates.

[0008] As a preferred embodiment of the present invention, the cleaning assembly includes a rotating shaft and a second motor. The rotating shaft is rotatably installed inside the housing, with one end extending to the outside of the housing. The second motor is installed on the side of the housing, and the second motor and the rotating shaft are connected by a transmission component. A cleaning roller is fixedly sleeved on the rotating shaft, and the cleaning roller and the rotating shaft are coaxially arranged. The surface of the cleaning roller is provided with bristles.

[0009] As a preferred embodiment of the present invention, in the initial state, the two drive rollers are located at both ends of the frame, and the belt does not contact the bristles on the surface of the cleaning roller.

[0010] As a preferred embodiment of the present invention, the flow guiding component includes two slide rails, both of which are fixed inside the housing and are arranged facing each other. Each slide rail has a sliding seat slidably disposed thereon. A swingable push plate is disposed between the two sliding seats. Limit blocks are fixed to the sides of both sliding seats. An assembly plate is fixed to the side of one of the sliding seats. A connecting rod is fixed to the side of the assembly plate. The end of the connecting rod away from the assembly plate extends to the outside of the housing.

[0011] As a preferred embodiment of the present invention, in the initial state, the push plate is in contact with the two limiting blocks, and the push plate is in a vertical state.

[0012] As a preferred embodiment of the present invention, the transmission assembly includes an eccentric wheel and a connecting plate. The eccentric wheel is fixedly sleeved on one end of the rotating shaft located outside the housing, and the eccentric wheel and the rotating shaft are eccentrically positioned. The eccentric wheel and the connecting rod are connected by the connecting plate. One end of the connecting plate is rotatably connected to the edge of the eccentric wheel, and the other end of the connecting plate is rotatably connected to the surface of the connecting rod.

[0013] As a preferred embodiment of the present invention, an eccentric wheel is fixedly sleeved on the rotating shaft, and an interception assembly is provided inside the housing. The interception assembly includes a shaft, which is fixed inside the housing. An installation plate is rotatably mounted on the shaft, and several thin rods are fixed to the side of the installation plate. A float is provided on one side of the installation plate, and the installation plate and the float are connected by a second support rod. A first support rod is fixed to the side of the float.

[0014] As a preferred embodiment of the present invention, the plurality of thin rods are arranged in a linear array along the width direction of the box.

[0015] A method for using a feeding device for daylily flavonoid extraction raw materials with a cleaning mechanism includes the following steps: Step 1: Start the belt conveyor and place the daylily raw materials evenly on the belt. At the same time, turn on the second motor to make the shaft drive the cleaning roller to rotate. The cleaning roller contacts the surface of the belt and continuously brushes to remove the daylily residue and dirt attached to the belt. The cleaning wastewater and residue fall into the box. Step 2: When the shaft rotates, it drives the cam to rotate at high speed. The cam periodically presses down the first support rod, causing the float to swing downward against the buoyancy of the water surface. The float drives the mounting plate and several thin rods to swing downward together through the second support rod until the thin rods are completely submerged below the water surface. Step 3: Under the continuous high-speed rotation of the cam, the thin rod remains in the position below the water surface. At this time, the thin rod will not hinder the free movement of the floating residue in the tank to one end of the tank. The wastewater generated during cleaning carries the suspended matter smoothly to the water collection area, achieving preliminary separation. Step 4: When the loading is complete or the residue inside the box needs to be cleaned, turn off the drive motor to stop the shaft from rotating, the cam stops pressing down, and the float floats upward and resets under its own buoyancy. The second support rod drives the mounting plate and the thin rod to swing upward, and the thin rod returns to the tilted interception state. Step 5: After the thin rod is reset, it intercepts the residual raw materials and soil particles floating on the water surface, causing them to stay on one side of the tank. The staff uses a filter or scraper to collect and remove the intercepted floating objects and process them uniformly. After cleaning is completed, the device can be restarted.

[0016] The present invention has the following beneficial effects: This raw material feeding device for daylily flavonoid production, equipped with a cleaning mechanism, uses movable transmission rollers and adjustable rollers to immerse the belt in water within the tank. Combined with the rotating bristles of the cleaning rollers, automatic washing is achieved, effectively replacing manual cleaning and improving cleaning efficiency and uniformity. It also prevents contamination of the raw materials by residues on the belt surface. The flow guiding component uses a rotating shaft to drive an eccentric wheel and connecting plate to reciprocate the push plate, generating a directional water flow that pushes floating residues to one end of the tank for easy centralized cleaning without requiring an additional power source. Furthermore, the interception component, through the linkage of a cam and a float plate, allows the thin rod to automatically sink during cleaning without obstructing the movement of floating objects, and automatically floats up when the machine stops to form an interception barrier, preventing the spread of floating objects. This further enhances the convenience and automation of floating object collection. The overall structure is compact, significantly reducing the frequency and intensity of manual maintenance.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example 1: This example describes a feeding device for daylily flavonoid extraction raw material with a cleaning mechanism, as disclosed in this example. Figure 1-8The system includes a frame 1, with two slide rails 11 at each end. The four slide rails 11 are arranged in pairs facing each other, and the length direction of the slide rails 11 is consistent with the length direction of the frame 1. Two first slide plates 2 are slidably installed at each end of the frame 1. The four first slide plates 2 are respectively arranged in pairs facing each other. A rotatable transmission roller 21 is installed between the two opposing first slide plates 2. The two ends of the transmission roller 21 are rotatably connected to the two opposing first slide plates 2, so that the transmission roller 21 can move synchronously with the first slide plate 2. Both ends of the transmission roller 21 extend into the corresponding slide rail 11. This design can use the slide rails 11 to limit the movement range of the transmission roller 21 and prevent it from deviating from the preset movement trajectory. The two transmission rollers 21 are connected by a belt 5. The belt 5 is wrapped around the outer circumference of the two transmission rollers 21 and transmits power by friction.

[0021] One of the first slide plates 2 has a mounting cover 3 fixed to its side. The mounting cover 3 is used to accommodate and protect the transmission components. A first motor 31 is mounted on the mounting cover 3. The output shaft of the first motor 31 is connected to the corresponding transmission roller 21. When the first motor 31 is running, it can drive the corresponding transmission roller 21 to rotate, thereby making the two transmission rollers 21 rotate synchronously with the belt 5. When the belt 5 is running, it can transport daylilies. In the production process of daylily flavonoids, daylilies, as the main raw material, need to be continuously fed into the washing or crushing equipment. The smooth conveying of the belt 5 can effectively improve the feeding efficiency and reduce the labor intensity of manual handling.

[0022] Two vertical plates 4 are fixed in the middle of the frame 1. Each vertical plate 4 is equipped with a movable second slide plate 41. The second slide plate 41 can slide vertically on the vertical plate 4 to adjust the height of the roller 42. The roller 42 is rotatably mounted between the two second slide plates 41. The axis of the roller 42 is parallel to the axis of the transmission roller 21. The belt 5 passes over the roller 42. The roller 42 plays a role in tensioning and redirecting, causing the belt 5 to bend downward in the middle. One of the vertical plates 4 is equipped with an adjustment mechanism to adjust the position of the second slide plate 41 on it. The operator can control the distance between the roller 42 and the frame 1 by adjusting the position of the two second slide plates 41. Adjusting the position of the roller 42 can change the depth of the belt 5 immersed in water. The adjustment method of the first slide plate 2 and the second slide plate 41 is existing technology and is not shown in the figure. It will not be described in detail here. For example, a screw and nut mechanism or a manual screw adjustment mechanism can be used. The operator only needs to turn the adjustment handwheel to move the second slide plate 41 up and down. The operation is simple and reliable.

[0023] A housing 6 is fixed on the frame 1, and water is stored inside the housing 6. The ends of two vertical plates 4 furthest from the frame 1 are fixedly connected to the inner bottom surface of the housing 6. In this way, the vertical plates 4 not only support the roller 42 but also connect the frame 1 and the housing 6 as a whole, improving the rigidity of the entire device. The housing 6 is arranged along the length of the frame 1 and is equipped with a cleaning assembly, which includes a rotating shaft 71 and a second motor 74. The rotating shaft 71 is rotatably installed inside the housing 6, and both ends of the rotating shaft 71 are connected to the side wall of the housing 6 through sealed bearings to prevent water leakage from the housing 6. One end of the rotating shaft 71 extends to the outside of the housing 6. The second motor 74 is installed on the side of the housing 6 and is typically a waterproof geared motor to adapt to the cleaning process. In a humid working environment, the second motor 74 is connected to the rotating shaft 71 via a transmission component 75. The transmission component 75 can be a belt drive. A cleaning roller 72 is fixedly sleeved on the rotating shaft 71, and the cleaning roller 72 is coaxially arranged with the rotating shaft 71. The length of the cleaning roller 72 is adapted to the width of the belt 5 to ensure that it can cover the effective working area of ​​the belt 5. The surface of the cleaning roller 72 is provided with bristles 73, which can be made of nylon or pig bristles with moderate hardness. This effectively removes raw material residue and dirt from the surface of the belt 5 without damaging the surface of the belt 5. In the initial state, the two transmission rollers 21 are located at the two ends of the frame 1, and the belt 5 does not contact the bristles 73 on the surface of the cleaning roller 72, forming a... Figure 3 The state shown is an initial state suitable for the normal feeding stage. At this time, belt 5 is only used to transport daylilies, does not come into contact with water, keeps them dry, and prevents the raw materials from getting damp.

[0024] When belt 5 needs cleaning, the operator first controls the two drive rollers 21 to move closer together, while simultaneously adjusting the position of roller 42 to move roller 42 downwards, ensuring that the tension of belt 5 is moderate, ultimately forming a state as shown. Figure 8As shown, when roller 42 moves downward, the second slide plate 41 is driven to descend via the adjusting mechanism, causing the middle area of ​​belt 5 to sink into the water inside the housing 6. In this situation, the area where belt 5 contacts roller 42 will penetrate deep into the housing 6 and be submerged in water. At the same time, part of belt 5 will contact the bristles 73 on the surface of cleaning roller 72, ensuring that the contact area between bristles 73 and belt 5 is completely submerged in water. During cleaning, the operator starts the first motor 31 and the second motor 74. When the first motor 31 is running, it can drive belt 5 to move, and the second motor 74... During operation, the cleaning roller 72 rotates. As the cleaning roller 72 rotates, the bristles 73 on its surface continuously brush the surface of the belt 5. Since the contact area between the belt 5 and the bristles 73 is submerged in water, the raw materials and dirt remaining on the surface of the belt 5 will be removed from the belt 5 under the action of water immersion and brushing, thus achieving automatic cleaning of the belt 5. Compared with manual cleaning, this automatic cleaning method is not only more efficient, but also cleans evenly and thoroughly, avoiding the food safety of daylily flavonoid products due to the growth of bacteria or mold caused by residues on the belt 5.

[0025] The housing 6 is equipped with a flow guiding component and a transmission component. The flow guiding component includes two slide rails 81, both of which are fixed inside the housing 6 and are arranged facing each other. Each slide rail 81 has a sliding seat 82 slidably mounted on it. A swingable push plate 84 is arranged between the two slide seats 82. The push plate 84 has a rectangular plate structure, and its width is close to the width of the housing 6 to maximize the propulsion of the water flow. Limiting blocks 821 are fixed to the sides of the two slide seats 82. The limiting blocks 821 are used to limit the swing angle of the push plate 84, so that it can only swing to one side while the other side is blocked. In the initial state, the push plate 84 is in contact with the two limiting blocks 821 and the push plate 84 is in a vertical state. At this time, the bottom end of the push plate 84 is submerged in the water. An assembly plate 85 is fixed to the side of one of the slide seats 82. A connecting rod 86 is fixed to the side of the assembly plate 85. The end of the connecting rod 86 away from the assembly plate 85 extends to the outside of the housing 6.

[0026] The transmission assembly includes an eccentric wheel 87 and a connecting plate 88. The eccentric wheel 87 is fixedly sleeved on one end of the rotating shaft 71 located outside the housing 6, and the eccentric wheel 87 and the rotating shaft 71 are eccentrically positioned. The eccentric wheel 87 and the connecting rod 86 are connected by the connecting plate 88. One end of the connecting plate 88 is rotatably connected to the edge of the eccentric wheel 87, and the other end of the connecting plate 88 is rotatably connected to the surface of the connecting rod 86. Both ends of the connecting plate 88 are respectively equipped with spherical bearings to accommodate the change in the connection angle when the eccentric wheel 87 rotates. When the rotating shaft 71 rotates, the eccentric wheel 87 performs circular motion, which is converted into the reciprocating linear motion of the connecting rod 86 through the connecting plate 88.

[0027] When the second motor 74 drives the rotating shaft 71 to rotate, the rotating shaft 71 drives the cleaning roller 72 to rotate, and the eccentric wheel 87 on the rotating shaft 71 rotates accordingly. During the rotation, the eccentric wheel 87 can continuously pull the connecting rod 86 through the connecting plate 88, causing the connecting rod 86 to drive the corresponding slide 82 to reciprocate, thereby causing the push plate 84 to reciprocate. This linkage design does not require an additional power source; it only uses the rotation of the cleaning roller 72 itself to drive the flow guiding component, saving energy and manufacturing costs. When the push plate 84 moves towards the center of the housing 6, it can push the water flow inside the housing 6, causing the water flow to surge towards one end of the housing 6. When the push plate 84 moves away from the center of the housing 6, it will swing under the resistance of the water flow. At this time, the push plate 84 cannot push the water flow because the push plate... The push plate 84 is rotatably connected to the slide 82, and the limiting block 821 only restricts the push plate 84 from swinging to one side. When the push plate 84 moves to the other side, the resistance of the water flow will cause the push plate 84 to swing backward around the pivot 71, thereby reducing the reverse thrust on the water flow. Therefore, the push plate 84 can continuously push the water flow towards one end of the tank 6 during the reciprocating movement, so that the water flow flows from one end of the tank 6 to the other end of the tank 6, forming a wave effect. This can effectively push the light residue floating on the water surface from one end of the tank 6 to the other end. In this process, the flowing water can push the raw material residue floating on the water surface towards one end of the tank 6, which is convenient for subsequent unified cleaning of the residue. By periodically opening the cleaning component and running the flow guiding component, the operator does not need to manually retrieve the floating objects, which greatly reduces the maintenance frequency and labor intensity.

[0028] Example 2: Based on Example 1, this example discloses a feeding device and method for daylily flavonoid extraction raw material with a cleaning mechanism, such as... Figure 9 As shown, the interior of the housing 6 is equipped with an interception assembly, which includes a shaft 91 fixed inside the housing 6. The shaft 91 is typically welded to the side wall of the housing 6, located near the end of the housing 6. A mounting plate 92 is rotatably mounted on the shaft 91, and the mounting plate 92 can swing freely around the shaft 91 within a certain angle range. Several thin rods 93 are fixed to the side of the mounting plate 92, arranged in parallel to form a comb-like structure, which can intercept material residues. A float plate 94 is provided on one side of the mounting plate 92, and the mounting plate 92 and the float plate 94 are connected by a second support rod 95. The float plate 94 can float on the water surface under the action of buoyancy. The float plate 94 is made of closed-cell foam plastic or hollow plastic sheet with a density less than water, which can provide sufficient buoyancy to lift the mounting plate 92 and the thin rods 93. When the float plate 94 floats on the water surface, the thin rods 93 are all inclined, forming a structure like... Figure 3In the state shown, the end of the thin rod 93 is submerged in water, while the root is slightly above the water surface. The bottom surface of the float 94 is fixed with a first support rod 941, which extends vertically downward. A cam 711 is fixedly sleeved on the rotating shaft 71, and the cam 711 is located inside the housing 6. The cam 711 and the rotating shaft 71 are connected and fixed by a key, and rotate synchronously with the rotating shaft 71. The first support rod 941 is set directly opposite the cam 711. When the cam 711 rotates, the profile surface of the cam will periodically press down on the first support rod 941.

[0029] When the rotating shaft 71 and cleaning roller 72 rotate, the rotating shaft 71 drives the cam 711 to rotate. As the cam 711 rotates, it presses down on the first support rod 941, causing the first support rod 941 to swing the float 94 downwards. The swinging of the float 94, via the second support rod 95, drives the mounting plate 92 to swing, which in turn causes several thin rods 93 to swing downwards. Under the continuous push of the cam 711, the thin rods 93 swing to a position below the water surface. At this point, the thin rods 93 no longer obstruct the movement of floating objects on the water surface. It should be noted that, due to the rotating shaft... The rotation speed of 71 and cam 711 is very fast, and the movement speed of float 94 under the action of buoyancy is limited. Therefore, under the action of the high-speed rotating cam 711, several thin rods 93 can be kept in the submerged position. Every time cam 711 rotates, the first support rod 941 is pressed down once. However, due to the large inertia of float 94 and water as a whole, the thin rods 93 will actually be stable in a low position and will not frequently jump up and down. Under these circumstances, several thin rods 93 will not prevent the raw material residue from floating towards one end of the tank 6.

[0030] When the cleaning component is running, the flow guiding component pushes the water flow, causing floating debris to gather at one end of the tank 6. At this time, the thin rod 93 is underwater, and the floating debris can smoothly pass over the thin rod 93 to reach the end collection area. When the rotating shaft 71 stops rotating, the cam 711 no longer presses the first support rod 941. At this time, the float plate 94 will float up under the action of buoyancy, and drive several thin rods 93 to reset. After resetting, the thin rods 93 extend out of the water surface at an angle again, forming an interception barrier. When several thin rods 93 are reset in place, they can intercept the floating debris and prevent it from floating. The object remains on one side of the container 6, facilitating subsequent unified processing of the floating object. After the cleaning work is completed, the thin rod 93 automatically rises, confining the floating object that has gathered at the end to the collection area and preventing it from spreading to other parts of the container 6. In this embodiment, through the cooperation of the cam 711 and the float 94, the thin rod 93 is automatically switched between the underwater hidden state and the water surface interception state. This does not affect the guiding effect during cleaning, and can maintain the concentrated collection of floating objects in the non-cleaning state, further improving the automation level and cleaning convenience of the device.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

6. A feeding device for daylily flavonoid extraction raw material with a cleaning mechanism according to claim 1, characterized in that, Several of the aforementioned thin rods (93) are arranged in a linear array along the width of the box (6).

7. A method of using a daylily flavonoid extraction raw material feeding device with a cleaning mechanism, based on any one of claims 1-6, characterized in that, Includes the following steps: Step 1: Start the belt (5) conveyor and place the daylily raw material evenly on the belt (5). At the same time, turn on the second motor (74) to make the rotating shaft (71) drive the cleaning roller (72) to rotate. The cleaning roller (72) contacts the surface of the belt (5) and continuously brushes to remove the daylily residue and mud attached to the belt (5). The cleaning wastewater and residue fall into the box (6). Step 2: When the rotating shaft (71) rotates, it drives the cam (711) to rotate at high speed. The cam (711) periodically presses down the first support rod (941), causing the float (94) to swing downward against the buoyancy of the water surface. The float (94) drives the mounting plate (92) and several thin rods (93) to swing downward together through the second support rod (95) until the thin rods (93) are completely submerged below the water surface. Step 3: Under the continuous high-speed rotation of the cam (711), the thin rod (93) remains in the position below the water surface. At this time, the thin rod (93) will not hinder the floating residue in the tank (6) from moving freely to one end of the tank (6). The wastewater generated by cleaning carries the suspended matter smoothly to the water collection area, achieving preliminary separation. Step 4: When the loading is completed or the residue in the box needs to be cleaned, turn off the drive motor to stop the shaft (71), stop the cam (711) from pressing down, and the float (94) floats up and resets under its own buoyancy. The second support rod (95) drives the mounting plate (92) and the thin rod (93) to swing upward, and the thin rod (93) returns to the tilted interception state. Step 5: After the thin rod (93) is reset, it intercepts the residual raw materials and soil particles floating on the water surface, causing them to stay on one side of the box (6). The staff uses a filter or scraper to collect and remove the intercepted floating objects and process them uniformly. After cleaning is completed, the device can be restarted.
