A cleaning and drying device for processing forsythia leaves

Abstract

This invention discloses a cleaning and drying device for processing Forsythia suspensa leaves, relating to the technical field of cleaning and drying devices. It includes a main unit comprising a cleaning frame and a water inlet pipe fixedly connected to one side of the cleaning frame. A feeding frame is fixedly connected to the upper surface of the cleaning frame. This invention utilizes the fixed frame to allow the upper and lower floating plates to swing up and down within it. When the cleaning fluid inside the cleaning frame swings, the upper and lower floating plates quickly float with the cleaning fluid. Furthermore, a connecting block connected to the lower floating plate alters the elastic potential energy of the first and second buffer springs through buoyancy. This further enhances the floating ability of the upper and lower floating plates by utilizing the elastic potential energy generated by the first and second buffer springs, thereby causing the Forsythia suspensa leaves inside to swing synchronously within the cleaning fluid to a certain extent, thus improving the cleaning effect of the equipment.

Description

Technical Field

[0001] This invention relates to the field of cleaning and drying equipment, and more particularly to a cleaning and drying device for processing forsythia leaves. Background Technology

[0002] Forsythia leaves are the tender leaves of the Forsythia plant, a member of the Oleaceae family. They are a common Chinese medicinal herb, typically used for clearing heat and detoxifying, reducing boils and carbuncles, dispersing wind-heat, and promoting urination. They can be used in combination with other Chinese medicinal herbs to treat diseases, or steeped in water for drinking, offering numerous health benefits.

[0003] Forsythia leaves grow in the wild and are usually harvested by hand. As a result, the leaves are often covered with dust and sand, and need to be washed and dried before they can be eaten. Currently, forsythia leaves are usually washed manually or by washing machine. However, the former wastes manpower and resources and increases the workload, while the latter, because the leaves are relatively light, causes all the leaves and lighter impurities to float on the surface of the water during washing, making it impossible to pick out the lighter impurities. After the leaves are washed out, they may still come into contact with lighter impurities, resulting in an unsatisfactory washing effect. Summary of the Invention

[0017] The beneficial effects of this invention are: 1. Using a cleaning frame, a feeding frame, a water inlet pipe, a sealing plate, a reciprocating motor, a traction motor, and a discharge trough, the internal structure of the floating cleaning unit is driven by the reciprocating motor and the traction motor respectively, so that the cleaning liquid can swing during the operation. Furthermore, the feeding frame allows the Forsythia leaf body to be quickly introduced into the equipment during operation. Furthermore, the water inlet pipe quickly introduces the cleaning liquid into the equipment, thereby quickly filling the cleaning frame with cleaning liquid. 2. By utilizing a fixed frame, a limiting ring plate, a first buffer spring, a lower floating plate, an upper floating plate, a connecting block, and a second buffer spring, the upper and lower floating plates can swing up and down within the fixed frame. When the cleaning fluid inside the cleaning frame swings, the upper and lower floating plates can quickly float with the cleaning fluid. Furthermore, by using the connecting block connected to the lower floating plate, the buoyancy force borne by the lower floating plate is transmitted to the first and second buffer springs. This buoyancy force changes the elastic potential energy of the first and second buffer springs. In addition, the elastic potential energy generated by the first and second buffer springs enhances the floating ability of the upper and lower floating plates, thereby causing the inner leaves of the forsythia to swing synchronously in the cleaning fluid to a certain extent, thus improving the cleaning effect of the equipment to a certain extent. 3. Utilizing a traction rope, rotating shaft, actuating plate, exhaust pipe, first conveyor belt, winding shaft, guide rod, sliding rod, connecting shaft, telescopic rod, second connecting shaft, third connecting shaft, and filter plate, the output shaft of the traction motor drives the winding shaft to rotate. The winding of the traction rope synchronously drives the upper floating plate to rotate around a fixed shaft, separating the upper and lower floating plates on one side. The forsythia leaves are then guided into the lower floating plate through the feed frame, and the upper floating plate is lowered by the traction rope. This allows the upper and lower floating plates to swing synchronously during the subsequent oscillation of the cleaning liquid. Furthermore, the rotating shaft drives the actuating plate to reciprocate, agitating the cleaning liquid and causing it to fluctuate to some extent. Simultaneously, impurities from the forsythia leaves are discharged downwards via the first conveyor belt, thus removing impurities to some extent. The sliding rod connects to the lower floating plate, allowing the lower floating plate to quickly change the position of the connecting shaft during floating, enabling the connecting shaft to slide synchronously within the lower floating plate and adapt quickly to changes in distance during the floating process. 4. Utilizing the second conveyor belt, L-shaped plate, micro push rod, connecting plate, sliding groove, telescopic rod, and second connecting shaft, after cleaning, the micro push rod drives the telescopic rod to slide in the sliding groove. Simultaneously, the telescopic structure of the telescopic rod allows the second connecting shaft to change its position relative to the micro push rod as it slides downwards. This causes the first conveyor belt to move the forsythia leaves to one side of the second conveyor belt to a certain extent. Furthermore, the electric push rod drives the sealing plate to be stored in the cleaning frame, thereby allowing the cleaning liquid carrying the forsythia leaves to be discharged into the discharge drying unit for treatment. 5. Utilizing a collection box, filter frame, drying box, air guide frame, triangular inclined plate, support rod, third conveyor belt, upper air intake pipe, lower air intake pipe, rotating shaft, air nozzle, rolling rod, drive motor, and connecting pipe, the output shaft of the drive motor drives the rotating shaft to rotate, thereby causing the third conveyor belt to simultaneously transport the forsythia leaves to one side of the drying box during rotation. Furthermore, the collection box collects and discharges the cleaning liquid, thus quickly separating the moisture to a certain extent. At the same time, the upper and lower air intake pipes inside the drying box spray gas onto the surface of the forsythia leaves, thereby rapidly drying them to a certain extent.

When the cleaning fluid inside the cleaning frame 101 swings, the upper floating plate 213 and the lower floating plate 212 can quickly float with the cleaning fluid. Furthermore, by utilizing the connecting block 216 connected to the lower floating plate 212, the buoyancy force borne by the lower floating plate 212 is transmitted to the first buffer spring 203 and the second buffer spring 217. This buoyancy force changes the elastic potential energy of the first buffer spring 203 and the second buffer spring 217. Furthermore, the elastic potential energy generated by the first buffer spring 203 and the second buffer spring 217 strengthens the floating ability of the upper floating plate 213 and the lower floating plate 212, thereby causing the inner leaves of the forsythia to swing synchronously in the cleaning fluid to a certain extent, thus improving the cleaning effect of the equipment to a certain extent. Using the traction rope 207, rotating shaft 208, actuating plate 209, exhaust pipe 210, first conveyor belt 211, take-up shaft 214, guide rod 215, sliding rod 220, connecting shaft 221, second connecting shaft 231, third connecting shaft 232, and filter plate 233, the output shaft of traction motor 106 drives the take-up shaft 214 to rotate. The winding of the traction rope 207 then synchronously drives the upper floating plate 213 to rotate around the fixed shaft 229, separating the upper floating plate 213 and the lower floating plate 212 on one side. The forsythia leaves are then guided into the lower floating plate 212 through the feed frame 102, and the upper floating plate 213 is lowered using the traction rope 207, allowing it to be placed in the subsequent cleaning liquid. During the movement, the upper floating plate 213 and the lower floating plate 212 swing synchronously. Furthermore, the rotating shaft 208 drives the agitator 209 to reciprocate, which stirs the cleaning liquid during the reciprocating motion, causing the cleaning liquid to fluctuate up and down to a certain extent. At the same time, impurities in the forsythia leaves are discharged downward through the first conveyor belt 211, thereby discharging impurities to a certain extent. The sliding rod 220 is slidably connected to the lower floating plate 212, allowing the lower floating plate 212 to quickly change the position of the connecting shaft 221 during the floating process, so that the connecting shaft 221 slides synchronously within the lower floating plate 212, allowing it to quickly adapt to distance changes during the floating process to a certain extent. Utilizing the second conveyor belt 206, L-shaped plate 222, micro push rod 223, connecting plate 224, sliding groove 225, telescopic rod 230, and second connecting shaft 231, after cleaning, the micro push rod 223 drives the telescopic rod 230 to slide within the sliding groove 225. Simultaneously, the telescopic structure of the telescopic rod 230 allows the second connecting shaft 231 to change its position relative to the micro push rod 223 as it slides downwards. This causes the first conveyor belt 211 to move the forsythia leaves towards the second conveyor belt 206 to a certain extent. Furthermore, the electric push rod 204 drives the sealing plate 205 to be retracted into the cleaning frame 101, thereby allowing the cleaning liquid carrying the forsythia leaves to be discharged into the discharge drying unit 300 for treatment. The system utilizes a collection box 301, a water filter frame 302, a drying box 303, an air guide frame 304, a triangular inclined plate 305, a support rod 306, a third conveyor belt 307, an upper air intake pipe 308, a lower air intake pipe 309, a rotating shaft 310, an air nozzle 311, a rolling rod 312, a drive motor 313, and a connecting pipe 314. The output shaft of the drive motor 313 drives the rotating shaft 310 to rotate, thereby causing the third conveyor belt 307 to simultaneously transport the forsythia leaves to one side of the drying box 303 during rotation. Furthermore, the collection box 301 collects and discharges the cleaning liquid, thereby quickly separating the moisture to a certain extent. At the same time, the upper air intake pipe 308 and the lower air intake pipe 309 inside the drying box 303 spray gas onto the surface of the forsythia leaves, thereby rapidly drying them to a certain extent.

[0033] Example 2: Refer to Figure 1 - Figure 2 and Figure 8 - Figure 9 The difference from Embodiment 1 is that: a rotating shaft 310 is rotatably connected to the inner surface of the filter frame 302, a third conveyor belt 307 is rotatably connected to the outer surface of the rotating shaft 310, and a drive motor 313 is fixedly connected to the upper surface of the collection box 301. The rotating shaft 310 is rotatably connected to the inner surface of the filter frame 302, providing support and a driving foundation for the third conveyor belt 307. The third conveyor belt 307 operates continuously under the drive of the rotating shaft 310, conveying the cleaned forsythia leaves from the filter frame 302 to the drying box 303. The drive motor 313 is fixed to the upper surface of the collection box 301, and its output shaft is connected to one of the rotating shafts 310, providing a power source for the third conveyor belt 307 and causing the third conveyor belt 307 to drip the residual water on the surface of the forsythia leaves downwards during transportation.

[0034] Furthermore, one end of the output shaft of the drive motor 313 is fixedly connected to one end of one set of rotating shafts 310. A guide frame 304 is fixedly connected to one side of the drying box 303, and a connecting pipe 314 is fixedly connected to one side of the guide frame 304. An upper air intake pipe 308 is fixedly connected to the lower surface of the drying box 303, and a jet nozzle 311 is fixedly connected to the lower surface of the upper air intake pipe 308. The drive motor 313 directly drives the rotating shaft 310 to rotate, thereby driving the third conveyor belt 307 to operate. The guide frame 304 is fixed to one side of the drying box 303 and is used to introduce external air into the drying box 303. The connecting pipe 314 is connected to the guide frame 304 to deliver gas to the guide frame 304. The upper air intake pipe 308 is fixed to the lower surface of the drying box 303, and the jet nozzles 311 evenly distributed on its lower surface spray gas downwards to blow and dry the upper surface of the forsythia leaves on the third conveyor belt 307.

[0035] Furthermore, a lower air intake pipe 309 is fixedly connected to the inner surface of the drying box 303. One end of both the upper air intake pipe 308 and the lower air intake pipe 309 is fixedly connected to one side of the air guide frame 304. A triangular inclined plate 305 is fixedly connected to one side of the drying box 303. A rolling rod 312 is rotatably connected to the inner surface of the drying box 303. The lower air intake pipe 309 is fixed to the inner surface of the drying box 303 and is located below the third conveyor belt 307. Together with the upper air intake pipe 308, it forms a bidirectional air blowing structure to simultaneously dry the upper and lower surfaces of the forsythia leaves, improving drying efficiency. One end of both the upper air intake pipe 308 and the lower air intake pipe 309 is connected to the air guide frame 304, sharing the same air source. The triangular inclined plate 309 is fixed to one side of the drying box 303. 5 is fixed to one side of the drying box 303, and its inclined surface guides the forsythia leaves output from the third conveyor belt 307 to slide smoothly into the next subsequent processing equipment or collection container; the rolling rod 312 is rotatably connected to the inner surface of the drying box 303, assisting in conveying materials when the forsythia leaves pass through, preventing material accumulation, and ensuring uniform drying.

[0036] Working principle: First, before the equipment is started, the traction motor 106 is in standby mode. The upper floating plate 213 hangs down naturally under its own weight and remains closed with the lower floating plate 212. The electric push rod 204 is in the extended state, which drives the sealing plate 205 to close the discharge trough 107 downward to prevent the cleaning liquid from leaking during the cleaning process. The water inlet pipe 103 is opened to inject cleaning liquid into the cleaning frame 101 until the liquid level reaches the preset height. During the injection of cleaning liquid, the air inlet pipe 219 introduces gas into the cleaning frame 101 through the air guide rod 218, which generates bubbles in the cleaning liquid and provides auxiliary agitation for subsequent cleaning. Secondly, before the cleaning fluid is injected, the traction motor 106 starts, and its output shaft drives the winding shaft 214 to rotate in the forward direction, winding the traction rope 207. After being guided by the guide rod 215, the traction rope 207 pulls the upper floating plate 213 upward, causing the upper floating plate 213 to rotate upward relative to the lower floating plate 212 around the fixed shaft 229. The fixed shaft 229 is fixed to the upper surface of the lower floating plate 212 by the fixing block 226. The sleeve 228 is rotatably connected to the outer surface of the fixed shaft 229 and fixedly connected to the upper floating plate 213, ensuring that the upper floating plate 213 rotates. After the upper floating plate 213 is opened to an appropriate angle, the operator puts the forsythia leaves to be cleaned into the cleaning frame 101 through the feeding frame 102. The forsythia leaves fall onto the upper surface of the lower floating plate 212. After feeding is completed, the traction motor 106 rotates in the opposite direction and slowly releases the traction rope 207. Under its own gravity, the upper floating plate 213 rotates downward around the fixed shaft 229 and gradually closes with the lower floating plate 212. The filter plate 233 fixedly connected inside the upper floating plate 213 protects the forsythia leaves inside the equipment during the falling process and keeps the leaves from floating out of the water. After the cleaning fluid is injected, the forsythia leaves are sealed in the cavity between the upper floating plate 213 and the lower floating plate 212, making full contact with the cleaning fluid. After the upper floating plate 213 and the lower floating plate 212 are closed, the reciprocating motor 105 starts, driving the rotating shaft 208 to rotate back and forth. The agitator plate 209, which is fixedly connected to the outer surface of the rotating shaft 208, swings back and forth in the cleaning fluid, generating periodic water flow disturbance. At the same time, the air inlet pipe 219 continuously introduces air bubbles into the cleaning fluid through the exhaust pipe 210, further enhancing the stirring effect. Under the combined action of the agitation of plate 209 and the bubbles, the cleaning fluid forms a wave-like motion within the cleaning frame 101. The lower floating plate 212, acting as a floating carrier, floats up and down with the liquid surface due to the buoyancy of the cleaning fluid. The floating motion of the lower floating plate 212 is transmitted to the connecting shaft 221 via the sliding rod 220. The connecting shaft 221 drives the connecting block 216 to slide within the fixed frame 201. The upper surface of the connecting block 216 is connected to a first buffer spring 203, and the lower surface is connected to a second buffer spring 217. Both are fixed to the fixed frame. At the corresponding position of 201, when the connecting block 216 slides up and down with the lower floating plate 212, the first buffer spring 203 and the second buffer spring 217 are alternately compressed and released, converting the floating energy of the lower floating plate 212 into elastic potential energy for storage and feedback. The waves of the cleaning fluid push the lower floating plate 212 to float. The lower floating plate 212 enhances the floating amplitude through the first buffer spring 203 and the second buffer spring 217. The enhanced floating further intensifies the wave disturbance of the cleaning fluid. During this process, the upper floating plate 213 and the lower floating plate 212... The plates 212 float synchronously, and the forsythia leaves between them are repeatedly submerged, lifted, and tumbled in the cleaning solution. Heavy impurities such as mud and dust adhering to the surface of the forsythia leaves are detached from the leaves under the action of gravity and settle at the bottom of the cleaning frame 101. Lighter impurities float to the water surface under the action of buoyancy and gather on the water surface above the upper floating plate 213. The filter plate 233 intercepts the forsythia leaves to prevent the leaves from floating to the water surface and ensures that the forsythia leaves always remain in the effective cleaning area between the upper floating plate 213 and the lower floating plate 212. Then, after the washing time reaches the preset time, the reciprocating motor 105 stops running, and the agitator plate 209 stops stirring. At this time, the electric push rod 204 starts, driving the sealing plate 205 to retract upwards, opening the discharge chute 107. The lower surface of the sealing plate 205 is an inclined plane, which cooperates with the inclined plane of the inner surface of the discharge chute 107, forming a smooth discharge channel after opening. The micro motor drives the first connecting shaft 227 to rotate, and the first connecting shaft 227 drives the first conveyor belt 211 to rotate. At the same time, the micro push rod 223 starts, and the telescopic rod 230 pushes the second connecting shaft 231 to slide downwards along the sliding groove 225 on the side of the connecting plate 224, causing the end of the first conveyor belt 211 to rotate downwards. The first conveyor belt 211 connects to the starting end of the second conveyor belt 206 and conveys the forsythia leaves on the lower floating plate 212 forward. The leaves fall onto the second conveyor belt 206 at the end. The second conveyor belt 206 is driven by another set of micro motors and rotates through the third connecting shaft 232 to further convey the forsythia leaves toward the discharge trough 107. The forsythia leaves slide out of the cleaning frame 101 through the discharge trough 107 and enter the discharge drying unit 300. During the discharge process, the conveying direction of the first conveyor belt 211 is matched with the water flow direction. The cleaning liquid carries the remaining impurities and is discharged from the discharge trough 107, while the forsythia leaves are intercepted and transferred under the active conveying of the conveyor belt, realizing the separation of materials and cleaning liquid. Finally, the forsythia leaves discharged from the discharge chute 107, along with the cleaning liquid, enter the filter frame 302 on the upper surface of the collection box 301. Through the filter screen structure on the surface of the third conveyor belt 307 inside the filter frame 302, the cleaning liquid flows into the collection box 301 via the third conveyor belt 307 and is collected and discharged. The forsythia leaves are intercepted above the third conveyor belt 307. The drive motor 313 starts, and its output shaft drives the rotating shaft 310 to rotate. The rotating shaft 310 drives the third conveyor belt 307 to operate. The forsythia leaves in the filter frame 302 are received by the third conveyor belt 307 and transported forward into the drying box 303. An external air source is connected to the air guide frame 304 through the connecting pipe 314. The air guide frame 304 distributes the gas to the upper air intake pipe 308 and the lower air intake pipe 309. The upper air intake pipe 308 is fixed to the lower surface of the drying box 303, and its lower surface has evenly distributed air jets. The nozzle 311 sprays gas downwards to sweep the upper surface of the forsythia leaves on the third conveyor belt 307; the lower air pipe 309 is fixed to the inner surface of the drying box 303 and located below the third conveyor belt 307 to sweep the lower surface of the forsythia leaves. The bidirectional air blowing structure ensures that the upper and lower surfaces of the forsythia leaves are simultaneously subjected to airflow, resulting in rapid evaporation of moisture and efficient drying. During the drying process, the rolling rod 312 is rotatably connected to the inner surface of the drying box 303. When the forsythia leaves pass through, the rolling rod 312 transports the leaves to prevent them from accumulating and ensures that the airflow evenly covers the leaf surface to a certain extent. The dried forsythia leaves continue to be conveyed forward with the third conveyor belt 307 and guided by the triangular inclined plate 305 fixedly connected to one side of the drying box 303, sliding down the inclined surface to the next processing equipment or collection container, thus completing the entire cleaning and drying process.
