Description

Technical Field

[0001] This invention relates to the field of equipment technology for the production and processing of traditional Chinese medicine, and in particular to a medicinal material processing device for processing traditional Chinese medicine. Background Technology

[0002] In the fields of traditional Chinese medicine preparations, decoction piece processing, and natural drug extraction, pressing is an indispensable key pre-processing step for many medicinal materials (especially seed-based medicinal materials). Its main objectives include: First, reducing the toxicity and moderating the medicinal properties of the materials. For example, for seed-based medicinal materials with high oil content, such as croton and sesame seeds, the oil often has a strong laxative effect or is irritating. Pressing to remove some of the oil to produce a "cream" can significantly reduce its toxic side effects and ensure clinical safety. Second, separating different medicinal parts to maximize their utilization. After pressing, the oil (or juice) and fibrous residue of some medicinal materials have drastically different medicinal effects and uses, requiring separate collection and utilization. A typical example is the "castor oil" obtained from pressing castor seeds and the residue "castor cake." Third, reducing the volume of the medicinal materials facilitates subsequent preparations. After removing excess oil, the medicinal materials are easier to pulverize and conveniently made into pills, powders, and other dosage forms.

[0003] Currently, conventional Chinese medicinal herb pressing equipment and processes generally suffer from low pressing efficiency and unsatisfactory oil yield. Most devices employ a simple single-pass pressing mode, where the material is pressurized only once, failing to fully extract the effective components. The cake-like structure formed after the first pressing still retains a significant amount of oil, but existing technologies lack efficient and continuous repressing methods for secondary or multiple deep pressings, resulting in incomplete oil extraction and waste of medicinal resources. Furthermore, in the pursuit of higher pressing efficiency in repressing process designs, achieving automatic material transfer and stable and reliable operation of the pressing components—such as ensuring the sealing of the receiving base plate and structural stability during the pressing process—has become a technical challenge affecting the degree of automation and production efficiency.

[0004] Therefore, developing a medicinal material processing device for traditional Chinese medicine that can achieve continuous and efficient pressing and has a stable locking mechanism is of great significance for improving the level of pre-processing technology for traditional Chinese medicine. Summary of the Invention

[0005] In order to overcome the shortcomings of existing Chinese medicine pressing equipment, such as incomplete pressing, low efficiency and poor stability of pressing containers, the technical problem of the present invention is to provide a medicinal material processing device for Chinese medicine processing.

[0007] In a preferred embodiment of the present invention, a linkage component for automatically opening and closing the bottom plate mechanism and discharging materials is further included; the linkage component includes connecting rods, fixed racks, worm gears, connecting gears, turbines, and nets; four connecting rods are vertically fixed between the inner side of the bottom wall of the support frame and the limiting frame, and a fixed rack is fixedly connected to each connecting rod; worm gears are symmetrically rotatably connected to the left and right sides of the storage box, and a connecting gear is coaxially fixed to one end of each worm gear; the two ends of the rotating shafts of the first rotating box and the second rotating box extend to the outside of the storage box and are fixedly connected to turbines, and each turbine meshes with the adjacent worm gear; a fixed ring is fixedly connected to the outer side of the bottom of the storage box, and the net is suspended on the fixed ring and located below the storage box.

[0008] In a preferred embodiment of the present invention, an oil collection and guiding structure is further included; an oil outlet pipe is fixedly connected to the outer edge of both the first rotating box and the second rotating box; a vertically arranged guide column is fixedly connected to the support frame, and each oil outlet pipe is inserted into the corresponding guide column and can slide up and down; the bottom wall of the support frame is designed as a slope structure, and an oil guide port is provided on one side of the slope bottom.

[0009] In a preferred embodiment of the present invention, the base plate mechanism is provided with an overlapping locking structure; specifically, the right edge of the first rotating box is provided with an overlapping protrusion, and the left edge of the second rotating box is provided with a matching overlapping slot; when the first rotating box and the second rotating box are closed, the overlapping protrusion is embedded in the overlapping slot.

[0010] In a preferred embodiment of the present invention, an automatic locking assembly for locking the base plate mechanism under load is further included; the automatic locking assembly includes a guide rod, a limiting frame, a connecting spring, a fixing rod, and a trapezoidal plate; the storage box is symmetrically fixedly connected to the front and rear sides with guide rods, the limiting frame is slidably sleeved between the two guide rods on the same side, and is elastically connected to the side wall of the storage box through the connecting spring; the first rotating box and the second rotating box have locking grooves on their sides that match the limiting frame; the bottom of the limiting frame is fixedly connected to a fixing rod, and the inner side of the fixing rod is provided with an inclined surface; each connecting rod is fixedly connected to a trapezoidal plate that cooperates with the inclined surface of the fixing rod.

[0011] In a preferred embodiment of the present invention, an automatic material distribution and shaking mechanism for uniformly distributing residue on the first filter plate is further included; the automatic material distribution and shaking mechanism includes a fixed seat, a rotating rod, a cam, a transmission wheel, a synchronous belt, a fixed frame, a rotating gear, a synchronous wheel, and a connecting rack; two fixed seats are fixed to the inner side of the bottom wall of the support frame and located below the first filter plate, and each fixed seat is rotatably connected to a rotating rod via a bearing, one end of the rotating rod is fixedly connected to a cam acting on the bottom of the first filter plate, and the other end is fixedly connected to a transmission wheel, the two transmission wheels being connected by a synchronous belt; the fixed frame is fixed to the rear side of the support frame, and a rotating gear is rotatably mounted on it, the shaft of the rotating gear is fixedly connected to a synchronous wheel, and the synchronous wheel is connected to a transmission wheel via another synchronous belt; the connecting rack is fixed to the pressure plate and meshes with the rotating gear.

[0012] In a preferred embodiment of the present invention, in the automatic locking assembly, the limiting frame tends to move inward and insert into the locking slot under the elastic force of the connecting spring; the inclined surface of the fixing rod cooperates with the trapezoidal plate on the connecting rod, so that the lifting movement of the storage box can be converted into the lateral movement of the limiting frame, thereby realizing the automatic unlocking and locking of the base plate mechanism.

[0013] In a preferred embodiment of the present invention, in the automatic material distribution and shaking mechanism, the lifting motion of the pressure plate is converted into the rotational motion of the rotating rod through the meshing of the connecting rack and the rotating gear and the transmission of the synchronous belt; the cam rotates with the rotating rod, thereby driving the first filter plate to produce periodic up and down displacement.

[0014] The beneficial effects are as follows: This device effectively solves the problem of insufficient oil extraction caused by the dense cake structure in traditional single-pass pressing through a continuous process of "one-time pressing to form cakes - lifting and crushing residues - closing and secondary pressing". The uniquely designed linkage discharge component (gear and rack and worm gear system) and the crushing structure (net bag with first filter plate) automatically complete the discharge, crushing and re-pressing of residues without manual intervention, which significantly improves the oil extraction efficiency and oil yield. It is especially suitable for the detoxification and oil removal treatment of oil-containing seed medicinal materials.

[0015] To improve the reliability and safety of equipment operation, this device integrates multiple locking and stabilizing mechanisms. The bottom plate mechanism is equipped with overlapping bosses and slots to ensure that a flat and sealed pressure-bearing surface is formed after closure. The added automatic locking component (limiting frame, spring and inclined plane linkage mechanism) can provide additional mechanical locking when the storage box is under load to prevent the bottom plate from opening accidentally, and automatically unlocks during material discharge. This achieves high stability in the pressing process and smooth linkage in the material discharge process, improving the overall safety and automation level of the equipment.

[0016] To address the issue of uneven residue distribution affecting pressing efficiency before secondary pressing, this device innovatively incorporates an automatic material-leveling and shaking mechanism driven by the main drive. This mechanism cleverly transforms the lifting motion of the pressing plate into the periodic lifting of the first filter plate by a cam through rack, pinion, and synchronous belt transmission, generating high-frequency vibration that automatically evens out the residue. This design ensures uniform pressure distribution during secondary pressing, further improving oil yield, and requires no additional power, achieving functional integration and energy efficiency optimization.

Detailed Implementation

[0025] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0026] Example 1: A medicinal material processing device for processing traditional Chinese medicine, such as... Figure 1 As shown, it includes a support frame 1 as the main load-bearing body. A cylinder 11, which serves as a power source, is installed on the top of the support frame 1. A pressure plate 12, which can reciprocate in the vertical direction, is fixed to the lower end of the piston rod of the cylinder 11. A storage box 14 for holding materials is slidably connected to the support frame 1 in the vertical direction. The storage box 14 has a cylindrical structure with both the top and bottom open.

[0027] To enable the lifting and linkage of the pressure plate 12 with the storage box 14, four connecting frames 13, symmetrically arranged on the left and right and distributed front and back, are fixedly connected to the top of the storage box 14; each connecting frame 13 has a hook at its top. Correspondingly, the pressure plate 12 is provided with a crossbar that can be hooked by the hook, so that the storage box 14 can be detachably suspended below the pressure plate 12 via the connecting frames 13. When the cylinder 11 drives the pressure plate 12 downward to press, the pressure plate 12 directly acts on the material in the storage box 14; when the cylinder 11 drives the pressure plate 12 upward, the storage box 14 is lifted together via the connecting frames 13.

[0028] The storage box 14 is equipped with an openable and closable bottom plate mechanism. For example... Figures 3-5As shown, the mechanism consists of a first rotating box 113 and a second rotating box 114, which are symmetrically distributed and have identical structures. The first rotating box 113 and the second rotating box 114 are rotatably connected to opposite side walls of the bottom of the storage box 14 via a rotating shaft, allowing them to be flipped open around their respective shafts. In the closed state, the inner sides of the first rotating box 113 and the second rotating box 114 abut against each other, jointly sealing the bottom opening of the storage box 14 to form a material-receiving base plate. To separate the oil immediately during the pressing process, a second filter plate 115 is fixedly connected to the opening of both the first rotating box 113 and the second rotating box 114.

[0029] The device is equipped with a receiving mechanism for repressing the residue after pressing and collecting the oil. For example... Figure 1 As shown, specifically, a first filter plate 112 is placed at the bottom of the support frame 1. A limiting frame 116 is fixed to the inner side of the bottom wall of the support frame 1. The first filter plate 112 is embedded in the limiting frame 116, and its top surface is flush with the top surface of the limiting frame 116, together forming a flat pressure-bearing plane for receiving the storage box 14 placed there and performing secondary pressing.

[0030] The device also includes a discharge assembly for automatically opening the bottom plate and discharging residue. This assembly includes a transmission mechanism and an actuator. Figures 2-4 As shown, the transmission mechanism specifically comprises: four vertically and symmetrically distributed connecting rods 15 fixedly connected between the inner side of the bottom wall of the support frame 1 and the limiting frame 116, with a fixed rack 16 fixedly connected to each connecting rod 15. Worms 18 are symmetrically and rotatably connected to the outer sides of the left and right side walls of the storage box 14, with a connecting gear 17 coaxially fixed to the outer end of each worm 18. The actuation mechanism is a turbine 19 and worm 18 system: both ends of the rotating shafts of the first rotating box 113 and the second rotating box 114 extend to the outer side of the storage box 14 and are fixedly connected to turbines 19, with each turbine 19 meshing with an adjacent worm 18.

[0031] When the storage box 14 is lifted upward by the pressure plate 12, the storage box 14 drives the worm gear 18 and connecting gear 17 on it to move upward together. During this process, each connecting gear 17 will mesh with the fixed rack 16 at the corresponding position, thereby driving the worm gear 18 to rotate, which in turn drives the shafts of the first rotating box 113 and the second rotating box 114 to rotate through the turbine 19, so that the two rotating boxes can be flipped downward and opened to discharge the pressed residue.

[0032] like Figure 2As shown, to collect and facilitate the transfer of solid residue discharged from the storage tank 14 after pressing, eight evenly distributed fixing rings 110 are fixed to the outer bottom of the storage tank 14. A flexible net bag 111 with an open top has its opening edge connected to the fixing rings 110 by ropes, thereby detachably suspending the net bag 111 directly below the storage tank 14. Initially and during the pressing process, the suspended net bag 111 is loosely stacked on the top surface of the first filter plate 112.

[0033] like Figure 2 and Figure 5 As shown, to further optimize the oil collection path and achieve complete separation and guided collection from solid residue, oil outlet pipes are fixedly connected to the outer edges of the first rotating box 113 and the second rotating box 114, which are far apart from each other. Correspondingly, vertically arranged guide columns 117 are fixedly connected to the support frame 1, which are symmetrically distributed from left to right. The outer end of each oil outlet pipe is inserted into the inner opening of the corresponding guide column 117, and can slide up and down in the inner cavity of the guide column 117 as the storage box 14 rises and falls, forming a sliding seal. In addition, the bottom wall of the support frame 1 is designed with a sloping structure, and an oil guide port is provided on one side of the slope to collect and discharge the oil produced by pressing.

[0034] Initially, the first rotating box 113 and the second rotating box 114 are closed to form a sealed bottom plate of the storage box 14. The medicinal materials to be processed are placed into the storage box 14 and laid flat on the second filter plate 115. The cylinder 11 is activated, driving the pressure plate 12 downward. Since the storage box 14 is suspended from the pressure plate 12 by the connecting frame 13, the two move downward synchronously until the bottom of the storage box 14 is pressed against the first filter plate 112. After that, the pressure plate 12 continues to move downward and gradually disengages from the connecting frame 13, eventually applying pressure directly to the medicinal materials in the storage box 14.

[0035] Under pressure, the oil in the medicinal material is squeezed out, passes through the second filter plate 115, and flows along the inclined bottom surfaces of the first rotating box 113 and the second rotating box 114 into the oil outlet pipe. It is then guided by the guide column 117 to the sloping bottom wall of the support frame 1 and finally collected by the oil guide port. Solid residue is trapped on the second filter plate 115, forming a cake-like structure after the first pressing.

[0036] After the initial pressing, cylinder 11 drives the pressure plate 12 to move upward and reset. Once the pressure plate 12 is reattached to the connecting frame 13, it causes the storage box 14 to rise as a whole. During the ascent, the connecting gear 17 meshes with the fixed rack 16, driving the first rotating box 113 and the second rotating box 114 to flip outward and open via the worm gear 18 and turbine 19. The cake-shaped residue falls from the bottom of the storage box 14 into the net bag 111 suspended below. Because the bottom of the net bag 111 is always supported by the first filter plate 112, the residue falls from a certain height and impacts the first filter plate 112, achieving physical breakage. The net bag 111 effectively prevents the residue from splashing.

[0037] After the residue is completely discharged, cylinder 11 drives pressure plate 12 to move downwards again, causing storage box 14 to move down. During the downward movement, connecting gear 17 and fixed rack 16 re-engage, driving the first rotating box 113 and the second rotating box 114 to flip inwards and reset, closing again to form the bottom plate of storage box 14. Storage box 14 continues to move downwards, and its bottom plate compacts the broken residue in mesh bag 111 onto the first filter plate 112. Pressure plate 12 continues to move downwards, applying secondary pressure to the residue through the bottom plate of storage box 14, further squeezing out residual oil. The oil produced by this pressing mainly flows through the first filter plate 112 into the sloping bottom wall below for collection.

[0038] After the second pressing, the press plate 12 moves upward, causing the storage box 14 to rise, and the net bag 111 returns to its natural hanging state. The workers can remove the net bag 111 filled with the final residue from the fixing ring 110, empty the residue, and hang the empty net bag 111 back. The device then returns to its initial state, ready for the next round of operation.

[0039] This device effectively solves the technical problem of insufficient oil extraction in a single pressing due to the densification of the cake structure, through a continuous process of "one-time pressing to form cakes—lifting and crushing the residue at the open bottom—closing the bottom for secondary pressing." The mechanically linked opening and closing bottom cover and crushing design achieve automatic crushing and re-pressing of the residue without manual intervention, significantly improving oil extraction efficiency and yield. It is particularly suitable for the detoxification, oil removal, or separation of oil-containing seed medicinal materials.

[0040] To ensure that the first rotating box 113 and the second rotating box 114 form a stable and flat pressure-bearing surface after closing, and to prevent interference during rotation, their structure has been specially designed. Specifically, an overlapping boss extending along the length of the first rotating box 113 is provided on its right edge, and correspondingly, an overlapping slot matching the shape of the overlapping boss is provided on the left edge of the second rotating box 114. When the two rotating boxes are driven to rotate upward to the closed position, the overlapping boss is precisely inserted into the corresponding overlapping slot, achieving lateral positioning and mutual support between the two.

[0041] The overlapping structure serves two purposes: firstly, it ensures a tight fit between the inner edges of the first rotating box 113 and the second rotating box 114, effectively preventing leakage of material or oil from the joint during pressing; secondly, it together forms a continuous and flat pressure surface, ensuring that pressure is evenly applied to the residue below during secondary pressing. Furthermore, the cooperative design of the boss and the slot ensures that the movement trajectories of the two plates do not interfere with each other when they rotate and open around their respective axes, improving the reliability of the mechanism's movement.

[0042] When the storage box 14 is filled with heavy medicinal materials, its bottom plate, consisting of two rotating boxes, can be initially closed by the self-locking mechanism of the turbine 19 and worm gear 18. However, under heavy material loads, there is still a risk of it accidentally tipping over and opening, causing material leakage during the pressing process, posing a safety hazard and affecting the normal operation of the pressing process. Therefore, an auxiliary limiting mechanism is needed that can provide reliable mechanical locking for the bottom plate under load-bearing conditions and automatically unlock during the discharge process to ensure the stability and safety of the pressing process and achieve linkage and coordination with the automatic opening and closing mechanism.

[0043] To ensure that the bottom plate (composed of the first rotating box 113 and the second rotating box 114) of the storage box 14 can be reliably locked when the medicinal materials are pressed, and to prevent accidental opening due to the gravity of the materials, the device is equipped with an automatic locking component.

[0044] like Figure 3 and Figure 4 As shown, specifically, guide rods 21 are symmetrically fixed to the front and rear side walls of the storage box 14. A limiting frame 2 is slidably fitted between the two guide rods 21 on each side. The limiting frame 2 is elastically connected to the side wall of the storage box 14 through symmetrically arranged connecting springs 22. Each connecting spring 22 is respectively fitted on the corresponding guide rod 21, and its elastic force normally drives the limiting frame 2 to move towards the center of the storage box 14.

[0045] The first rotating box 113 and the second rotating box 114 have locking slots on their sides (corresponding to the positions of the limiting frame 2) that match the shape of the limiting frame 2. When the base plate is in the closed state, the limiting frame 2 extends inward under the action of the spring and inserts into the locking slots on the sides of the two rotating boxes, forming a mechanical pin-type lock. This provides additional load-bearing protection for the base plate and prevents it from rotating only under the self-locking of the worm gear 18 and the worm 19.

[0046] To achieve automatic linkage between the locking assembly and the base plate's opening and closing action, a horizontal fixing rod 23 is fixedly connected to both the left and right sides of the bottom of the limiting frame 2, located below the worm gear 18. The inner side of the fixing rod 23 is machined with an inclined surface. Correspondingly, on each vertical connecting rod 15, at a position along the movement path of the fixing rod 23, a trapezoidal plate with a guide inclined surface is fixedly connected.

[0047] When the storage box 14 is lifted upwards, it first causes the guide rod 21, the limiting frame 2, and the fixing rod 23 to rise synchronously. The inclined surface at the end of the fixing rod 23 contacts the inclined surface of the trapezoidal plate on the connecting rod 15. Under the guidance of the inclined surface, the fixing rod 23 is pushed outwards, thereby causing the limiting frame 2, which is fixed to it, to overcome the elastic force of the connecting spring 22 and slide outwards along the guide rod 21, so that it exits from the locking slots of the first rotating box 113 and the second rotating box 114, completing the mechanical unlocking of the bottom plate. Subsequently, the storage box 14 continues to rise, and the connecting gear 17 meshes with the fixed rack 16, thereby driving the worm gear 18 and the turbine 19 to flip the bottom plate downwards and open, realizing the discharge of materials.

[0048] As the storage box 14 moves downwards in preparation for repressurization, the connecting gear 17 first engages with the fixed rack 16, driving the base plate to flip upwards and close. The storage box 14 continues to move downwards, and the guide rod 21 and fixed rod 23 descend accordingly. When the fixed rod 23 moves down to separate from the trapezoidal plate on the connecting rod 15, the external guiding force applied to the fixed rod 23 disappears. At this time, the compressed connecting spring 22 releases its elasticity, driving the limiting frame 2 to slide inwards along the guide rod 21 to reset. Its end re-inserts into the locking slots of the closed first rotating box 113 and second rotating box 114, mechanically locking the base plate again, preparing for the next load-bearing press.

[0049] Example 2: After the initial pressing, regardless of whether the residue is in the form of a dense cake or loose granules, it may accumulate locally or be unevenly distributed when it falls from a height onto the first filter plate 112. This uneven material layer will lead to uneven pressure distribution during the second pressing, with insufficient pressure in some areas, thus affecting further oil extraction and reducing the overall oil yield. Existing technologies typically rely on manual leveling, which is inefficient and inconsistent. Therefore, an auxiliary mechanism is needed that can automatically and evenly level the residue on the first filter plate 112 to ensure uniform pressure transmission during the second pressing, thereby improving the efficiency of oil extraction during the second pressing.

[0050] To ensure that the residue on the first filter plate 112 is evenly distributed before the second pressing, the device is equipped with an automatic material distribution and shaking mechanism.

[0051] like Figure 6 and Figure 7As shown, specifically, two fixed seats 38 are fixedly connected to the inner side of the bottom wall of the support frame 1, located inside the first filter plate 112. Each fixed seat 38 is rotatably connected to a horizontally arranged rotating rod 32 via a bearing. One end of each rotating rod 32 extends downwards towards the first filter plate 112, and a cam 37 is fixedly connected to that end; the other end of the rotating rod 32 extends outwards, passes through the side wall of the support frame 1 and forms a rotatable engagement with it, and a transmission wheel 35 is fixedly connected to the exposed end. The two transmission wheels 35 are connected by a synchronous belt 36 to ensure that the two rotating rods 32 can rotate synchronously.

[0052] To convert the vertical reciprocating motion of the pressure plate 12 into the rotational motion of the rotating rod 32, a fixed frame 34 is fixedly connected to the rear side of the support frame 1, on which a rotating gear 31 is rotatably mounted. One end of the rotating shaft of the rotating gear 31 extends outward and is fixedly connected to a synchronous pulley 33. This synchronous pulley 33 is connected to an adjacent transmission pulley 35 via another synchronous belt 36. At the same time, a vertically arranged connecting rack 3 is fixedly connected to the pressure plate 12, which meshes with the rotating gear 31, thus forming a rack and pinion transmission system. When the pressure plate 12 rises and falls, the two rotating rods 32 and their cams 37 can be driven to rotate synchronously through this transmission chain.

[0053] When the pressure plate 12 moves up and down, the connecting rack 3 fixed to it moves accordingly, driving the rotating gear 31 to rotate. The rotating gear 31 drives one rotating rod 32 to rotate through the synchronous pulley 33 and the synchronous belt 36, and then drives another rotating rod 32 to rotate synchronously through the transmission pulley 35 and the synchronous belt 36. The two rotating rods 32 drive the cam 37 on them to rotate synchronously.

[0054] During rotation, when the cam 37 reaches its highest point, it lifts the first filter plate 112 upwards, causing it to rise briefly against gravity. After the cam 37 passes its highest point, the first filter plate 112 and the residue it carries quickly fall back under its own weight. As the cam 37 continues to rotate, the first filter plate 112 produces continuous, periodic up-and-down vibrations.

[0055] Under this high-frequency vibration, the residue accumulated on the surface of the first filter plate 112, whether it is blocky residue after falling or granular residue that has slid down, is redistributed due to inertia and micro-throwing effect, achieving automatic leveling. After the material layer reaches a uniformly leveled state, when the pressure plate 12 performs secondary pressing on it through the bottom plate of the storage box 14, the connecting rack 3 and the rotating gear 31 no longer mesh, the first filter plate 112 no longer vibrates, and the pressure of the pressure plate 12 is evenly transmitted to all parts of the residue, avoiding the problem of insufficient local pressing caused by uneven force, thereby significantly improving the oil extraction efficiency and oil yield in the secondary pressing stage.

[0056] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
