Description

Technical Field

[0001] This utility model relates to the field of ginseng pressing technology, specifically to a stamping die for pressing ginseng. Background Technology

[0002] The fleshy root of ginseng is a tonic, suitable for regulating blood pressure, restoring heart function, treating neurasthenia and general weakness, and also has expectorant, stomachic, diuretic, and stimulant effects. The stems, leaves, flowers, fruits, and processing byproducts of ginseng are all raw materials for light industry, and can be processed into products such as cigarettes, alcohol, tea, crystals, and ointments containing ginseng.

[0003] A search revealed that patent application CN202121906361.4 discloses a pressing device for extracting ginseng root juice. While this device uses a combination of a pressing roller and a feeding plate to press the ginseng, and the residue is conveyed by a transmission roller and collected inside the frame to prevent mixing with the liquid and facilitate residue cleaning, achieving waste separation, the device relies solely on the pressing roller for a single pressing method. This results in insufficient extraction of ginseng root juice, a low extraction rate, and an inability to fully utilize the effective components in ginseng. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a stamping die for pressing ginseng, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A stamping die for pressing ginseng includes a hydraulic cylinder, the output end of which is a pressing rod, and the hydraulic cylinder is provided with a first oil circuit interface and a second oil circuit interface.

[0007] Below the extrusion rod are a first cylinder, a second cylinder, and a third cylinder. An end cap is installed at the end of the third cylinder. The extrusion rod includes a first telescopic rod, a second telescopic rod, and a third telescopic rod, with the diameters of the first, second, and third telescopic rods decreasing progressively. A first compression chamber is formed inside the first cylinder, a second compression chamber is formed inside the second cylinder, and a third compression chamber is formed inside the third cylinder. The inner diameters of the first, second, and third compression chambers decrease progressively. The diameters of the first, second, and third compression chambers are matched with those of the first, second, and third telescopic rods, respectively. The extrusion is performed step by step through the first compression chamber and the first telescopic rod, the second compression chamber and the second telescopic rod, and the third compression chamber and the third telescopic rod.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the bottom end of the first cylinder is provided with a first wedge, and the top end of the second cylinder is provided with a groove. The first cylinder and the second cylinder are spliced ​​together by the first wedge and the groove.

[0010] The beneficial effects of adopting the above-mentioned further solutions are:

[0011] This splicing method ensures a more precise and tight connection between the first and second cylinders. The wedge and groove engagement provides positioning during splicing, ensuring accurate relative positioning of the two cylinders and guaranteeing the coaxiality of the first and second compression chambers. This facilitates the smooth transition of the extrusion rod from the first to the second compression chamber for pressing operations, improving the assembly accuracy and operational stability of the mold. Furthermore, this splicing method facilitates disassembly and assembly, making mold maintenance, cleaning, or component replacement easier and faster, reducing maintenance costs and time.

[0012] Furthermore, the bottom end of the second cylinder is provided with a second wedge, and the third cylinder is also provided with a slot. The second cylinder and the third cylinder are spliced ​​together by the second wedge and the slot, and the included angle between the first wedge and the second wedge is ninety degrees.

[0013] The beneficial effects of adopting the above-mentioned further solutions are:

[0014] The first and second wedges are joined at a 90-degree angle, enhancing the stability and torsional resistance of the entire mold structure. During the pressing process, the ginseng is subjected to complex reaction forces. This staggered joint structure effectively disperses these forces, preventing the mold from shifting or deforming under pressure, ensuring the relative positions of the compression chambers remain constant, thus guaranteeing smooth pressing and consistent pressing results. Furthermore, it facilitates disassembly and assembly, aiding in mold maintenance and component replacement.

[0015] Furthermore, after the first, second, and third cylinders are spliced ​​together, they are locked and fixed with bolts.

[0016] The beneficial effects of adopting the above-mentioned further solutions are:

[0017] Bolt tightening provides reliable securing force to the assembled cylinders, forming a robust whole. During high-pressure pressing, it prevents loosening or displacement between the cylinders, ensuring the mold's sealing and stability and avoiding pressure leakage and poor pressing results caused by cylinder loosening. Furthermore, the bolt connection is adjustable; minor gaps or loosening during mold use can be adjusted by tightening the bolts, extending the mold's lifespan.

[0018] Furthermore, the second cylinder has a first guide cavity at the top of the second compression chamber, through which the first compression chamber transitions to the second compression chamber.

[0019] The beneficial effects of adopting the above-mentioned further solutions are:

[0020] The first guide cavity serves as a transition and guide, ensuring a smoother and more stable transition of the extrusion rod from the first compression chamber to the second compression chamber. It guides the extrusion rod, reducing deviation and wobbling during the transition, and ensuring the coaxiality of the extrusion rod and the second compression chamber. This allows pressure to be evenly transmitted to the ginseng, improving the precision and effectiveness of the pressing process. Furthermore, the guide cavity prevents the ginseng from getting stuck or blocked when entering the second compression chamber, ensuring the continuity and efficiency of the pressing process.

[0021] Furthermore, the third cylinder has a second guide cavity at the top of the third compression chamber, through which the second compression chamber transitions to the third compression chamber.

[0022] The beneficial effects of adopting the above-mentioned further solutions are:

[0023] Similar to the first guide cavity, the second guide cavity provides a smooth transition and guidance for the extrusion rod as it moves from the second compression cavity into the third compression cavity. During multi-stage pressing, the required precision of the extrusion rod's movement increases with the gradual increase in pressure. The second guide cavity ensures that the extrusion rod enters the third compression cavity accurately, further improving the precision and stability of the pressing process. Simultaneously, it helps prevent ginseng from accumulating or clogging during the transition between different compression cavities, ensuring the smooth operation of the entire pressing process.

[0024] Furthermore, the third cylinder has a third guide cavity and a storage cavity at the bottom end of the third compression cavity, and the third compression cavity transitions to the storage cavity through the third guide cavity, with the end cap installed inside the storage cavity.

[0025] The beneficial effects of adopting the above-mentioned further solutions are:

[0026] The third guide chamber provides a smooth transition channel for the pressed ginseng residue, allowing it to smoothly enter the storage chamber from the third compression chamber. The storage chamber provides a centralized space for the ginseng residue, facilitating unified collection and processing. The end caps prevent leakage of residue within the storage chamber, ensuring a clean working environment. Furthermore, the storage chamber design facilitates further processing of the residue, such as secondary pressing or other comprehensive utilization, improving resource utilization.

[0027] This utility model provides a stamping die for pressing ginseng. It has the following beneficial effects:

[0028] By using a series of compression chambers—the first compression chamber and the first telescopic rod, the second compression chamber and the second telescopic rod, and the third compression chamber and the third telescopic rod—the ginseng undergoes a gradual change in pressure. This ensures that pressure is applied evenly to all parts of the ginseng, preventing damage to its active ingredients due to excessive local pressure, maximizing the preservation of its nutritional value, and guaranteeing both the pressing effect and product quality.

[0029] The first, second, and third cylinders are joined together using wedges and slots, and then secured with bolts. This modular design makes mold assembly and disassembly extremely convenient. When the mold needs maintenance, parts replacement, or cleaning, the operation can be completed quickly, reducing downtime, improving production efficiency, and also lowering maintenance difficulty and costs.

[0030] The first guide cavity on the second cylinder, and the second and third guide cavities on the third cylinder, serve as transitional guides between the telescopic rods and compression chambers at different levels. During the pressing process, the guide cavities guide the telescopic rods accurately into the corresponding compression chambers, ensuring the precision and stability of the pressing action, reducing the probability of uneven pressing caused by positional deviations, and making the entire pressing process more reliable.

[0031] The third cylinder has a storage chamber at the bottom of the third compression chamber, where the pressed ginseng product falls directly. This not only facilitates product collection and processing but also reduces manual intervention and the risk of product contamination. Furthermore, this design helps achieve continuous production, further improving production efficiency. Attached Figure Description

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Please see Figures 1 to 5 As shown, the embodiments provided by this utility model are as follows: Example

[0043] A stamping die for pressing ginseng includes a hydraulic cylinder 1, the output end of which is a pressing rod 2. The hydraulic cylinder 1 is provided with a first oil passage interface 101 and a second oil passage interface 102. A first cylinder 3, a second cylinder 4, and a third cylinder 5 are placed below the pressing rod 2. An end cap 6 is installed at the end of the third cylinder 5. The pressing rod 2 includes a first telescopic rod 201, a second telescopic rod 202, and a third telescopic rod 203, with the diameters of the first telescopic rod 201, the second telescopic rod 202, and the third telescopic rod 203 decreasing in that order. A first compression chamber 302 is formed inside the first cylinder 3, and a compression chamber 302 is formed inside the second cylinder 4. There is a second compression chamber 403, and a third compression chamber 504 is provided inside the third cylinder 5. The inner diameters of the first compression chamber 302, the second compression chamber 403 and the third compression chamber 504 decrease in that order. The diameter of the first compression chamber 302 is matched with the diameter of the first telescopic rod 201, the diameter of the second compression chamber 403 is matched with the diameter of the second telescopic rod 202, and the diameter of the third compression chamber 504 is matched with the diameter of the third telescopic rod 203. The compression is performed step by step through the first compression chamber 302 and the first telescopic rod 201, the second compression chamber 403 and the second telescopic rod 202, and the third compression chamber 504 and the third telescopic rod 203. Example

[0044] To improve the assembly accuracy, stability, and ease of maintenance of molds, for example, such as Figures 1 to 5 As shown, this utility model also includes: a first wedge 301 at the bottom of the first cylinder 3, and a groove at the top of the second cylinder 4. The first cylinder 3 and the second cylinder 4 are spliced ​​together by the first wedge 301 and the groove. This splicing method makes the connection between the first cylinder 3 and the second cylinder 4 more precise and tight. The cooperation between the wedge and the groove can play a positioning role during splicing, ensuring the accurate relative position of the two cylinders, ensuring the coaxiality of the first compression chamber 302 and the second compression chamber 403, which is conducive to the smooth transition of the extrusion rod 2 from the first compression chamber 302 to the second compression chamber 403 for pressing operations, and improving the assembly accuracy and operational stability of the mold. Meanwhile, this splicing method facilitates disassembly and assembly, making mold maintenance, cleaning, or component replacement easier and faster, reducing maintenance costs and time. The bottom of the second cylinder 4 is equipped with a second wedge 401, and the third cylinder 5 also has a slot. The second cylinder 4 and the third cylinder 5 are spliced ​​together via the second wedge 401 and the slot, with the included angle between the first wedge 301 and the second wedge 401 being 90 degrees. This 90-degree splicing method enhances the stability and torsional resistance of the entire mold structure. During the pressing process, ginseng is subjected to complex reaction forces. This staggered splicing structure effectively disperses these forces, preventing the mold from shifting or deforming under the influence of forces, ensuring the relative positions of the compression chambers remain unchanged, thus guaranteeing the smooth progress of the pressing process and the consistency of the pressing effect. Furthermore, it is also easy to disassemble and assemble, which facilitates mold maintenance and component replacement. After the first cylinder 3, the second cylinder 4, and the third cylinder 5 are assembled, they are locked in place by bolts 7. The locking of bolts 7 provides reliable fastening force to the assembled cylinders, making the entire mold a solid whole. During high-pressure pressing, it can prevent loosening or displacement between the cylinders, ensuring the sealing and stability of the mold and avoiding pressure leakage and poor pressing effect caused by cylinder loosening. At the same time, the bolt 7 connection is adjustable. When the mold has slight gaps or loosening during use, it can be adjusted by tightening bolts 7, extending the service life of the mold. Example

[0045] To improve pressing precision, ensure the continuity of the pressing process, and facilitate residue handling, for example, such as Figures 1 to 5As shown, this utility model also includes: a second cylinder 4 with a first guide cavity 402 at the top of the second compression chamber 403. The first compression chamber 302 transitions to the second compression chamber 403 through the first guide cavity 402. The first guide cavity 402 serves as a transition and guide, making the extrusion rod 2 enter the second compression chamber 403 more smoothly and steadily from the first compression chamber 302. It can guide the extrusion rod 2, reduce the offset and shaking of the extrusion rod 2 during the transition process, and ensure the coaxiality of the extrusion rod 2 and the second compression chamber 403, so that the pressure can be evenly transmitted to the ginseng, improving the accuracy and effect of pressing. Furthermore, the guide cavity prevents ginseng from getting stuck or blocked when entering the second compression chamber 403 from the first compression chamber 302, ensuring the continuity and efficiency of the pressing process. The third cylinder 5 has a second guide cavity 501 at the top of the third compression chamber 504. The second compression chamber 403 transitions to the third compression chamber 504 through the second guide cavity 501. Similar to the first guide cavity 402, the second guide cavity 501 provides a good transition and guidance for the extrusion rod 2 as it enters the third compression chamber 504 from the second compression chamber 403. During multi-stage pressing, as the pressure gradually increases, the movement precision of the extrusion rod 2 requires higher accuracy. The second guide cavity 501 ensures that the extrusion rod 2 enters the third compression chamber 504 accurately, further improving the precision and stability of the pressing process. Simultaneously, it helps prevent ginseng from accumulating or clogging during the transition between different compression chambers, ensuring the smooth progress of the entire pressing process. The third cylinder 5, located at the bottom of the third compression chamber 504, has a third guide chamber 502 and a storage chamber 503. The third compression chamber 504 transitions to the storage chamber 503 via the third guide chamber 502. The end cap 6 is installed inside the storage chamber 503. The third guide chamber 502 provides a smooth transition channel for the pressed ginseng residue, allowing it to smoothly enter the storage chamber 503 from the third compression chamber 504. The storage chamber 503 provides a centralized storage space for the ginseng residue, facilitating unified collection and processing. The end cap 6 prevents residue leakage within the storage chamber 503, ensuring a clean working environment. Furthermore, the design of the storage chamber 503 facilitates further processing of the residue, such as secondary pressing or other comprehensive utilization, improving resource utilization.

[0046] Working principle:

[0047] First, the first cylinder 3, the second cylinder 4, and the third cylinder 5 are joined together using wedges and slots. The bottom wedge of the first cylinder 3 is embedded into the top slot of the second cylinder 4, and the bottom wedge of the second cylinder 4 mates with the slot of the third cylinder 5, with the included angle between the two wedges being 90 degrees. After the joining is completed, bolts 7 are used to tighten it to ensure the stability of the mold structure. Then, the ginseng is placed into the compression chamber of the first cylinder 3, and the hydraulic cylinder 1 is connected to the hydraulic system through the oil circuit interface to provide power for the pressing operation.

[0048] The hydraulic system is activated, and hydraulic cylinder 1 drives the extrusion rod 2 downward. The extrusion rod 2 consists of telescopic rods with progressively decreasing diameters, corresponding to a progressively decreasing inner diameter of the compression chamber inside the cylinder, which is adapted to the diameter of the telescopic rods. As the extrusion rod 2 descends, the first-stage telescopic rod enters the first compression chamber 302, performing initial pressing on the ginseng. Because the diameters of the two are matched, the pressure is evenly applied to the ginseng. At this time, the ginseng is subjected to initial compression, and some juice begins to seep out from the gap between the telescopic rod and the compression chamber.

[0049] As the extrusion rod 2 continues to move downwards, it passes through the guide cavity and enters the second compression chamber 403, further increasing the pressure on the ginseng. The guide cavity ensures that the extrusion rod accurately enters the corresponding compression chamber, making the pressure more concentrated and allowing more ginseng juice to seep out from the gaps.

[0050] As the extrusion rod 2 continues to press down, the third-stage telescopic rod, guided by the guide cavity, enters the third compression chamber 504 for deep pressing. At this time, the ginseng is subjected to high-intensity compression, and a large amount of juice seeps out through the gaps. The seeping juice is collected by a special collection device for subsequent processing.

[0051] After pressing, the ginseng residue is pushed by the extrusion rod 2 and enters the storage chamber 503 through the guide cavity at the bottom of the third compression chamber 504. The guide cavity provides a channel for the residue to enter the storage chamber 503, and the end cap 6 seals the storage chamber 503 to prevent residue leakage, thus achieving effective collection of ginseng residue.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
