Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine preparation technology, and in particular to a Chinese medicinal herb pressing machine and pressing method. Background Technology

[0002] A herbal extractor is a type of mechanical equipment specifically used in the production process of traditional Chinese medicine preparations. It is mainly used to squeeze the herbs after decocting, soaking, or extracting them, thereby separating the medicinal juice from the residue. It is commonly found in Chinese herbal medicine processing plants, pharmaceutical factories, and workshops producing prepared Chinese medicines, and is a key piece of equipment commonly used in the extraction process.

[0003] In practice, some problems still exist: 1. Currently, the extraction and pressing processes of traditional Chinese medicine are mostly completed using single-stage pressing equipment consisting of a pressing box, a feeding hopper, and basic transmission components. The common practice is to extract liquid from the medicinal materials by stirring or squeezing, and then rely on a fixed screen for one-time solid-liquid separation. When processing traditional Chinese medicine materials with high fiber content and high viscosity, the screen is easily blocked by the residue, resulting in poor liquid output and downtime for cleaning. At the same time, the residue removal process mostly relies on manual labor or simple scraping structures, and the flow path of the residue inside the residue removal box is unclear, which easily leads to residue and secondary pollution. The medicinal liquid is usually discharged through a single path with few filtration stages, making it difficult to balance flow rate and clarity. On the other hand, when the speed or pressure is increased to maintain pressing stability, the frictional heat inside the equipment will affect the preservation of heat-sensitive components, and the difficulty of cleaning and disinfection will increase, which is not conducive to the requirements of continuous and clean production.

[0004] 2. To improve the purity of the drug solution, some companies in the industry have implemented secondary filtration after solid-liquid separation. However, existing technologies mostly use manual valve switching with a single or parallel filter tube, which results in slow switching response and poor synchronization. Frequent valve start-stop leads to increased wear on seals and filter cotton, and once the filter tube becomes clogged, it often requires shutdown for maintenance, affecting the production line's cycle time. At the same time, the power and control chains in existing equipment are relatively dispersed. For example, there is a lack of coordinated control between the drive shaft and gearbox, and between the stirring rollers. This can easily cause asynchrony between the pressing and filtration stages, resulting in pulsation and backflow of the drug solution in the collection and transportation stages, such as in the collection tank and connecting pipes, thus affecting the stability of subsequent fine filtration. Summary of the Invention

[0005] (a) Technical problems to be solved In order to solve the above-mentioned problems in the prior art, the present invention provides a Chinese herbal medicine pressing machine and pressing method, which solves the problems mentioned in the background art.

[0006] (II) Technical Solution To achieve the above objectives, the main technical solution adopted by the present invention is as follows: A Chinese herbal medicine pressing machine and pressing method include a connecting frame, an auxiliary slag removal mechanism inside the connecting frame, and an auxiliary filtration mechanism on one side of the connecting frame. The auxiliary slag removal mechanism includes a screen, a scraper, a first motor, a connecting member, and a slag removal box. The interior of the slag removal box is rotatably connected to the screen. The output end of the first motor is fixedly connected to the top of the connecting member. The connecting member is fixedly connected to the middle of the screen. The bottom end of the scraper is attached to the top of the screen and fixedly connected to one side of the inner wall of the slag removal box. The auxiliary filtration mechanism includes a valve, a gear cylinder, a rack, a movable support, and a lead screw. The middle of the lead screw is threaded to the movable support. Both sides of the movable support are provided with racks. The inner sides of the two racks are meshed with gear cylinders. The bottom ends of the two gear cylinders are respectively fixedly connected to the rotating shafts of the two valves.

[0007] An installation box is fixedly connected to the other side of the connecting frame. A pressing box is fixedly connected to the top of the installation box. A feed hopper is fixedly connected to the top of the pressing box. A guide plate is fixedly connected to the inner wall of the slag removal box.

[0008] Two stirring rollers are rotatably connected to the inner wall of the pressing box, and a gearbox is fixedly connected to the inner side of the connecting frame. The two stirring rollers are respectively fixedly connected to the two output shafts of the gearbox, and the first motor is fixedly connected to the inner wall of the connecting frame.

[0009] A second motor is fixedly connected to one side of the inner wall of the connecting frame, and a connecting rod is fixedly connected to the output end of the second motor. One end of the connecting rod is connected to the inner side of the gearbox.

[0010] The inner wall of the slag removal box is fixedly connected to a collection trough, and the bottom end of the collection trough is fixedly connected to a connecting pipe. The collection trough is placed at the bottom of the screen.

[0011] One end of the connecting pipe is fixedly connected to an adapter, and both sides of the adapter are fixedly connected to guide pipes. One end of each of the two guide pipes is connected to a filter pipe, and the two filter pipes are respectively connected to one end of two valves. The other end of each of the two valves is fixedly connected to a transmission pipe.

[0012] A third motor is fixedly connected to the inner side of the adapter. The output end of the third motor is fixedly connected to one end of the lead screw. The other end of the lead screw is rotatably connected to a limit rail. One end of the limit rail is fixedly connected to the bottom of the inner side of the adapter. The bottom end of the movable support is slidably connected to the top end of the limit rail.

[0013] An extension plate is fixedly connected to the top of the movable support, and fixed plates are fixedly connected to both sides of the extension plate. One end of each of the two fixed plates is fixedly connected to the inner side of the two racks.

[0014] The front and back sides of the extension plate are fixedly connected to reinforcing plates, and one end of each reinforcing plate is fixedly connected to the middle of the inner side of the two racks.

[0015] A method for pressing traditional Chinese medicine includes the following steps: S1: Feeding Steps Users feed the pre-treated Chinese medicine raw materials into the pressing box through the feeding hopper to ensure that the raw materials are evenly fed into the equipment; S2: Preliminary pressing step The second motor is started, which drives the connecting rod to rotate. The connecting rod drives the gearbox to rotate, which in turn drives the two stirring rollers in the pressing box to rotate, squeezing and turning the incoming Chinese medicine, so that the medicinal liquid in the medicinal materials is initially extracted. S3: Residue Separation Step The first motor is started, and the first motor drives the screen to rotate through the connecting parts. The medicine residue produced by pressing rotates in the screen and is scraped off by the scraper to the bottom of the residue removal box for collection, thereby achieving the separation of medicine residue and medicine liquid. S4: Medicine Liquid Collection Steps The liquid medicine separated by the screen flows into the collection tank at the bottom of the slag removal box and is then transported to the inside of the adapter through the connecting pipe to prepare for subsequent filtration. S5: Secondary filtration step The liquid medicine enters two filter tubes through two guide tubes on the outside of the adapter for secondary filtration to remove fine impurities from the liquid medicine. S6: Valve switching procedure Start the third motor, which drives the lead screw to rotate. The lead screw drives the movable support to slide along the limit rail. The movable support drives the rack to move linearly through the extension plate and the fixed plate. The rack meshes with the gear cylinder to intermittently open or close the two valves, so that the two filter tubes work alternately. S7: Continuous Operation and Maintenance Procedures When one filter tube is in operation, the other filter tube can be closed or under maintenance to reduce the wear and tear on individual filter tubes, prevent filter cotton from clogging and causing downtime, and ensure the continuity and stability of the drug filtration process.

[0016] (III) Beneficial Effects The beneficial effects of this invention are: 1. In this invention, by setting up an auxiliary slag removal mechanism, after the Chinese herbal medicine enters the pressing box, the second motor drives the connecting rod to rotate, thereby driving the gearbox to rotate the two stirring rollers, achieving uniform pressing of the medicinal materials and ensuring full extraction of the medicinal liquid. During the separation of the medicinal liquid and the slag, the first motor drives the connecting part to continuously rotate the screen. The slag rotates with the screen, and the scraper adheres to the screen surface, effectively scraping off the residue and collecting it in the collection tank at the bottom of the slag removal box. This allows the user to easily remove the residue and perform secondary pressing. This structure not only improves the juice yield of the Chinese herbal medicine but also prevents the residue from accumulating on the screen and causing blockages, ensuring long-term stable operation of the equipment. At the same time, after separation, the medicinal liquid can directly enter the interior of the adapter through the collection tank and connecting pipe, avoiding leakage of the medicinal liquid, maintaining a clean production environment, and improving the practicality and hygiene of the equipment.

[0017] 2. In this invention, an auxiliary filtration mechanism is provided. After the liquid medicine enters the adapter through the collection tank, it enters two filter tubes through the guide pipe for secondary filtration, effectively improving the clarity of the liquid medicine. The third motor drives the lead screw to rotate, causing the moving support to slide along the limit guide rail. The moving support then drives the rack to move through the extension plate and the fixed plate. After the rack meshes with the gear cylinder, it can intermittently control the two valves to open or close alternately. This structure realizes the alternating operation of the two filter tubes. On the one hand, it avoids the wear and tear caused by long-term use of a single filter tube, extending the service life of the filter tube and the internal filter cotton. On the other hand, when one filter tube is blocked, the other filter tube can be put into use immediately without interrupting the liquid medicine filtration process, ensuring continuous output of liquid medicine and improving production efficiency. At the same time, the valve switching structure is reasonably designed, and the user can flexibly control the start and stop of the third motor to realize the free switching of the filter tubes between different working states. It has the beneficial effects of convenient maintenance, compact structure and reliable operation. Attached Figure Description

The inner sides of the two racks 304 are meshed with gear cylinders 305. The bottom ends of the two gear cylinders 305 are fixedly connected to the rotating shafts of the two valves 306 respectively.

[0022] Optionally, an installation box 204 is fixedly connected to the other side of the connecting frame 1. A pressing box 203 is fixedly connected to the top of the installation box 204, and a feed hopper 205 is fixedly connected to the top of the pressing box 203.

In actual implementation, the two stirring rollers 210 can rotate synchronously, thereby fully squeezing and turning the traditional Chinese medicine entering the pressing chamber 203, so that the medicinal liquid in the medicinal material can be quickly extracted. The stable transmission structure of the gearbox 212 ensures the efficiency and uniformity of the pressing process.

[0024] Optionally, a second motor 207 is fixedly connected to one side of the inner wall of the connecting frame 1. A connecting rod 208 is fixedly connected to the output end of the second motor 207, and one end of the connecting rod 208 is connected to the inner side of the gearbox 212. In actual implementation, after the second motor 207 starts, it transmits power to the gearbox 212 through the connecting rod 208, ensuring that the two output shafts of the gearbox 212 drive the stirring roller 210 to operate stably, thereby realizing continuous pressing of Chinese medicine raw materials. This structure has a short and direct power transmission path, reducing energy loss and improving operational reliability.

[0025] Optionally, a collection tank 214 is fixedly connected to the inner wall of the slag removal box 201, and a connecting pipe 4 is fixedly connected to the bottom end of the collection tank 214. The collection tank 214 is placed at the bottom of the screen 209. In actual implementation, the liquid medicine falls directly into the collection tank 214 after being filtered by the screen 209, avoiding liquid medicine retention or loss. The connecting pipe 4 at the bottom of the collection tank 214 can smoothly guide the liquid medicine into the adapter 301, ensuring continuous and stable liquid medicine transmission. The whole process remains clean and hygienic, reducing the intervention of manual operation.

[0026] Optionally, an adapter 301 is fixedly connected to one end of the connecting pipe 4. Both sides of the adapter 301 are fixedly connected to guide pipes 303. One end of each guide pipe 303 is connected to a filter pipe 302. Each filter pipe 302 is connected to one end of each of two valves 306. The other end of each valve 306 is fixedly connected to a transmission pipe 307. In actual implementation, the adapter 301 can evenly distribute the liquid medicine to the two guide pipes 303. The two filter pipes 302 perform secondary filtration to further remove fine impurities. The valves 306 control the flow direction of the liquid medicine, and the transmission pipes 307 smoothly transport the filtered liquid medicine to the downstream process.

One end of the limit rail 309 is fixedly connected to the bottom of the inner side of the connector 213, and the bottom end of the movable support 312 is slidably connected to the top end of the limit rail 309. In actual implementation, after the third motor starts, it can drive the lead screw 308 to rotate. The rotation of the lead screw 308 causes the movable support 312 to move along the limit rail 309, realizing intermittent control of the opening and closing of the valve 306, ensuring that the two filter tubes 302 work alternately, and effectively improving the stability and continuity of the filtration system.

[0028] Optionally, an extension plate 311 is fixedly connected to the top of the movable support 312, and fixed plates 313 are fixedly connected to both sides of the extension plate 311. One end of each fixed plate 313 is fixedly connected to the inner side of the two racks 304. In actual implementation, the extension plate 311 serves as a structural extension, driving the fixed plates 313 to reliably move in linkage. The fixed plates 313 then push the racks 304 to move linearly. The racks 304 mesh with the gear cylinder 305 to achieve the opening and closing switching of the valve 306. The entire action is coordinated and stable, ensuring the reasonable distribution of the liquid flow direction and improving the filtration efficiency.

[0029] Optionally, reinforcing plates 310 are fixedly connected to both the front and back sides of the extension plate 311, with one end of each reinforcing plate 310 fixedly connected to the inner center of each rack 304. In actual implementation, the reinforcing plates 310 enhance the stability and deformation resistance between the extension plate 311 and the rack 304, making the rack 304 more stable under stress, avoiding displacement and wear during long-term operation, and improving the overall durability and reliability of the device.

[0030] Optionally, a method for pressing traditional Chinese medicine includes the following steps: S1: Feeding Steps The user feeds the pre-treated Chinese medicine raw materials into the pressing box 203 through the feeding hopper 205 to ensure that the raw materials enter the equipment evenly; S2: Preliminary pressing step The second motor 207 is started, which drives the connecting rod 208 to rotate. The connecting rod 208 drives the gearbox 212 to rotate, thereby driving the two stirring rollers 210 in the pressing box 203 to rotate, squeezing and turning the incoming Chinese medicine, so that the medicinal liquid in the medicinal material is initially extracted. S3: Residue Separation Step The first motor 206 is started, and the first motor 206 drives the screen 209 to rotate through the connector 213. The medicine residue produced by pressing rotates in the screen 209 and is scraped off by the scraper 202 to the bottom of the residue box 201 for collection, thereby realizing the separation of medicine residue and medicine liquid. S4: Medicine Liquid Collection Steps The liquid medicine separated by the screen 209 flows into the collection tank 214 at the bottom of the slag removal box 201, and is then transported to the inside of the adapter 301 through the connecting pipe 4 to prepare for subsequent filtration. S5: Secondary filtration step The liquid medicine enters the two filter tubes 302 through the two guide tubes 303 on the outside of the adapter 301 for secondary filtration to remove fine impurities from the liquid medicine. S6: Valve 306 Switching Procedure The third motor is started, which drives the lead screw 308 to rotate. The lead screw 308 drives the movable support 312 to slide along the limit rail 309. The movable support 312 drives the rack 304 to move linearly through the extension plate 311 and the fixed plate 313. The rack 304 meshes with the gear cylinder 305 to intermittently open or close the two valves 306, so that the two filter tubes 302 work alternately. S7: Continuous Operation and Maintenance Procedures When one filter tube 302 is in operation, the other filter tube 302 can be in a closed or maintenance state to reduce the wear of a single filter tube 302, avoid clogging of the filter cotton and causing downtime, and ensure the continuity and stability of the drug filtration process.

[0031] Working Principle: This medicinal herb press mainly consists of a connecting frame 1, an auxiliary slag removal mechanism 2, an auxiliary filtration mechanism 3, a mounting box 204, a pressing box 203, a feeding hopper 205, a stirring roller 210, a gearbox 212, a first motor 206, a second motor 207, a third motor, a scraper 202, a screen 209, a slag removal box 201, a collection tank 214, a connecting pipe 4, an adapter 301, a guide pipe 303, a filter pipe 302, a valve 306, a lead screw 308, a movable support 312, an extension plate 311, a fixed plate 313, a rack 304, a gear cylinder 305, a limit rail 309, and a reinforcing plate 310. Its overall function is to achieve efficient pressing of Chinese medicinal herbs, slag collection, and multi-stage filtration of the medicinal liquid, ensuring the purity of the medicinal liquid and the continuous operation of the equipment. Okay, during the operation, the user first feeds the processed traditional Chinese medicine into the pressing box 203 through the feed hopper 205. The pressing box 203 contains two stirring rollers 210, which are connected to the gearbox 212 inside the connecting frame 1. After the second motor 207 starts, its output drives the connecting rod 208 to rotate. The connecting rod 208 then drives the gear mechanism inside the gearbox 212 to rotate, thereby rotating the two stirring rollers 210. The rotation of the stirring rollers 210 can play a preliminary role in turning and compacting, so that the traditional Chinese medicine entering the pressing box 203 is gradually squeezed under pressure, thus achieving the initial extraction of the medicinal liquid. Subsequently, the first motor 206 starts, and its output drives the screen 209 to rotate through the connecting piece 213. The screen 209 is arranged in the residue removal area. Inside the box 201, the main function is to initially separate the solid residue from the liquid medicinal juice produced after pressing the traditional Chinese medicine. As the screen 209 rotates, the residue rotates and is gradually pushed towards the scraper 202. The scraper 202 is in close contact with the top of the screen 209. During the rotation of the screen 209, the residue adhering to the screen 209 can be effectively scraped off and collected at the bottom of the slag removal box 201 for subsequent collection and secondary pressing. This ensures the cleanliness and unobstructed flow of the screen 209 surface and improves the pressing efficiency. The filtered medicinal liquid flows into the collection trough 214 located at the bottom of the slag removal box 201 after separation by the screen 209. The bottom of the collection trough 214 is connected to the adapter 301 through the connecting pipe 4. The medicinal liquid flows through the connecting pipe 4 in sequence. Inside the adapter 301, guide tubes 303 are fixedly connected to both sides of the adapter 301. The guide tubes 303 further introduce the medicine into two independent filter tubes 302. The filter tubes 302 perform secondary fine filtration to further remove fine impurities from the medicine. In the auxiliary filtration mechanism 3, valves 306 are installed at the outlet ends of both filter tubes 302. Their opening and closing states are controlled by a rack and pinion mechanism 304, a gear cylinder 305, and a lead screw 308. After the third motor starts, its output end drives the lead screw 308 to rotate. The middle part of the lead screw 308 is threadedly connected to the movable support 312. The rotation of the lead screw 308 causes the movable support 312 to slide along the limit rail 309. During the movement of the movable support 312, the extension plate 311 moves accordingly.The fixed plate 313 drives two racks 304 to make linear displacement. The movement of the racks 304 meshes with the gear cylinder 305, causing the gear cylinder 305 to rotate, thereby realizing the alternating control of the rotating shafts of the two valves 306. This design enables the intermittent opening and closing of the two valves 306, allowing the two filter tubes 302 to work alternately. Its advantages are: firstly, it effectively reduces the workload of a single filter tube 302, reducing wear caused by long-term continuous operation, thus extending the service life of the filter tubes 302 and the internal filter cotton; secondly, when a filter tube 302 becomes clogged or requires maintenance, the corresponding valve 306 can be temporarily closed while the other filter tube 302 is opened to continue working, thus avoiding the impact on the overall machine's production efficiency due to filtration system downtime. Users can turn off the third motor to fix the valve 306 state when needed, or restart the third motor for alternating switching, ensuring flexible and efficient operation.

10. A method for pressing traditional Chinese medicine, characterized in that: Applied to the press according to any one of claims 1-9, comprising the following steps: S1: Feeding Steps The user feeds the pre-treated Chinese medicine raw materials into the pressing box (203) through the feeding hopper (205) to ensure that the raw materials enter the equipment evenly; S2: Preliminary pressing step Start the second motor (207), the second motor (207) drives the connecting rod (208) to rotate, the connecting rod (208) drives the gearbox (212) to rotate, thereby driving the two stirring rollers (210) in the pressing box (203) to rotate, squeezing and turning the incoming Chinese medicine, so that the medicinal liquid in the medicinal material is initially extracted; S3: Residue Separation Step Start the first motor (206), which drives the screen (209) to rotate through the connector (213). The dregs produced by pressing rotate in the screen (209) and are scraped off by the scraper (202) to the bottom of the dregs box (201) for collection, thereby achieving the separation of dregs and liquid medicine. S4: Medicine Liquid Collection Steps The liquid medicine separated by the screen (209) flows into the collection tank (214) at the bottom of the slag removal box (201) and is transported to the inside of the adapter (301) through the connecting pipe (4) to prepare for subsequent filtration; S5: Secondary filtration step The liquid medicine enters the two filter tubes (302) through the two guide tubes (303) on the outside of the adapter (301) for secondary filtration to remove fine impurities in the liquid medicine; S6: Valve (306) switching steps Start the third motor, which drives the lead screw (308) to rotate. The lead screw (308) drives the movable support (312) to slide along the limit rail (309). The movable support (312) drives the rack (304) to move linearly through the extension plate (311) and the fixed plate (313). The rack (304) meshes with the gear cylinder (305) to intermittently open or close the two valves (306), so that the two filter tubes (302) work alternately. S7: Continuous Operation and Maintenance Procedures When one filter tube (302) is in operation, the other filter tube (302) can be in a closed or maintenance state to reduce the wear of a single filter tube (302), avoid filter cotton blockage causing downtime, and ensure the continuity and stability of the drug filtration process.
