Abstract
Description
Technical Field
[0001] This invention relates to intelligent Chinese medicine cabinets, particularly a composite conveyor belt type bottom discharge unit cabinet for bulk Chinese medicinal slices. Background Technology
[0002] As a treasure of traditional Chinese medicine, Chinese medicine has played a tremendous role in the health of the Chinese people throughout its thousands of years of history. However, the Chinese medicine industry itself still has many aspects that need improvement and enhancement.
[0003] Traditional Chinese medicine dispensing is usually done manually. When a patient goes to the pharmacy to pick up their medicine, the pharmacist manually retrieves, weighs, and prepares the medicine from the corresponding drawer in the medicine cabinet according to the prescription. This manual dispensing method has disadvantages such as low efficiency, high error rate, and time and labor consumption.
[0004] Technical personnel in the field of traditional Chinese medicine (TCM) have proposed several solutions for automating TCM dispensing and administration. One solution is the "Automated TCM Dispensing Machine" (CN107200156), which consists of a weighing unit, a negative pressure collector, and a controller. The weighing unit comprises multiple weighing devices, a main dispensing pipe, and a temporary dispensing device. It independently weighs each TCM herb and uses negative pressure to collect the concentrated herbs for centralized dispensing. Another solution is the "Fully Automatic Intelligent TCM Dispensing Machine for Medicinal Herbs" (CN104828445), which has at least two rows of dispensing units on its frame. Each dispensing unit consists of a storage box, a linear motion module, a tilting hopper, and a linear feeding hopper. Controlled by a mechanical automation program, it features accurate measurement and fast dispensing speed.
[0005] None of the above technical solutions can centrally and automatically complete all operations such as adding, cleaning, retrieving, and dispensing medicine within a single medicine cabinet. Summary of the Invention
[0006] The purpose of this invention is to provide a composite conveyor belt type bottom discharge belt for bulk Chinese herbal medicine slices unit cabinet, which aims to automatically complete operations such as opening the medicine door to add medicine, pressing the medicinal slices, multiple times shaving and taking medicine, and metering and dispensing medicine within a single unit cabinet, in order to match the inventor's "Intelligent Dispensing and Dispensing System for Chinese Herbal Medicine Slices in Smart Pharmacy".
[0007] The objective of this invention is achieved as follows: A composite conveyor belt type bottom discharge unit medicine cabinet for bulk Chinese herbal medicine slices, the unit medicine cabinet is composed of a cabinet box and a hopper assembly. The hopper assembly is formed by the hopper and the top cover plate being integrated. The rectangular top cover plate is fastened to the upper end face of the top opening of the cabinet box. The hopper extends into the inner cavity of the cabinet box. The medicine addition port at the front of the top cover plate is hinged with a medicine addition door with side baffles on both sides. A baffle box for inserting the side baffle of the medicine addition door when the medicine addition door is closed is fixed on the inner side wall of the medicine addition port on both sides of the top cover plate. The front door of the cabinet is set at the front of the cabinet box via a door hinge, and the rear door for dispensing medicine is set on the rear panel of the cabinet box. The hopper rear plate is an inclined plate. Upper and lower rollers are installed on the outer walls above and below the strip groove of the hopper rear plate, respectively. The annular steel strip used to seal the strip groove is hung on the upper and lower rollers. The hinge pressure plate assembly structure is as follows: multiple pressure rods are fixed longitudinally and at equal intervals on a horizontal bar. Each pressure rod has a hinge pressure plate installed at the front via a torsion spring. The counterweight is fixed laterally on the rear of all pressure rods. When not subjected to external force, the hinge pressure plates of all pressure rods form an adjacent integral pressure plate under the force of the torsion spring. A fixed seat is fixed on the longitudinal fixed shaft fixed in the middle of the horizontal bar for bolting to the lifting mechanism. The fixed seat is equipped with a lowering limit switch and a lifting limit switch. A clamping mechanism for the gripper to grab is vertically arranged on the horizontal plate of the fixed seat: the upper and lower ends of the central shaft of the clamping fixed shaft are respectively a frustum and a disc, and an inverted frustum symmetrical to the shape of the frustum, i.e., the movable clamping shaft, is movably fitted on the central shaft. The longitudinal fixing shaft of the aforementioned hinge pressure plate assembly extends into the inner cavity of the hopper through a through hole in the annular steel strip and the strip groove of the hopper. Only the fixing block and the snap-fit mechanism of the hinge pressure plate assembly are located on the outside of the hopper. A hinged retractable frame is installed on the upper part of the rear wall of the hopper cavity; The lifting mechanism used for gripping the hinge plate assembly has the following structure: a slide rail is fixed to the outer wall of the hopper rear plate parallel to the hopper's groove; a slider is slidably mounted on the slide rail; a fixed seat for the hinge plate assembly is fixed to the slider; a lead screw is mounted on the outer wall of the hopper rear plate parallel to the slide rail via an upper bearing seat and a lower bearing seat; a driven gear is mounted on the outer end of the lead screw extending from the lower bearing seat; a drive gear mounted on the reduction motor shaft mounted on the lower bearing seat meshes with the driven gear; a nut is screwed onto the lead screw; a gripper plate is fixed to the nut; multiple gripper plate pins with springs are respectively located in openings on the side wall of the gripper plate; spring covers seal these openings; and clamping screws are screwed onto the gripper plate pins. Pressed against the spring cover, when the geared motor drives the gripper disc to move downward, the truncated cone of the locking mechanism overcomes the spring force and causes the gripper disc pin to extend outward, thereby causing the cone to rise and enter the upper chamber of the gripper disc. At the same time, the gripper disc touches the lifting limit switch, causing the geared motor to stop rotating. Under the action of the spring force, the gripper disc pin returns to its original shape and is locked under the cone, thus realizing the gripping action of the gripper disc. After the gripping action is completed, when the gripper disc continues to move downward under the drive of the geared motor, the inverted cone located in the lower chamber of the gripper disc rises and squeezes the gripper disc pin into the upper chamber of the gripper disc, and finally causes the entire locking mechanism to disengage from the upper chamber of the gripper disc, thus completing the release action of the gripper disc. The bottom discharge and medicine collection device is fixed to the opening of the horizontal bottom plate of the hopper by means of a clamping strip embedded in the clamping groove of the hopper. The structure of the bottom discharge and medicine collection device is as follows: The drive wheel is a cylindrical body with a flange on both end faces; the geared motor consists of a motor and a reducer, and the geared motor is installed on the vertical section of the outer side of the left side plate.

One end of the connecting rod is hinged to the toggle plate, and the other end of the connecting rod is hinged to the upper sealing plate.
[0015] Compared with the prior art, the present invention has the following technical features and advantages: 1. Independence: Each unit of medicine cabinet is an independent entity. As long as it is connected to an external power source and communication network, it can independently complete the tasks of adding, retrieving, and dispensing medicine.
[0016] 2. One-click connection mode: The cable trays on the cabinet are reserved channels for connecting the unit medicine cabinet to the power cord and communication line outside the cabinet. The unit medicine cabinet can be connected to the power and communication through the plug-in terminals in the cable trays.
[0017] 3. Adaptability: By using different hoppers, bottom discharge and medicine-taking devices, and counterweights of different weights, it can adapt to changes in the shape and density of medicinal materials and complete the extraction of different medicinal materials.
[0018] 4. Modular Design: All devices within the unit medicine cabinet, such as the dispensing and retrieval device, metering pusher and tilter, metering calibration device, rear door device, dosing door, and front door, adopt a modular design, possessing relatively independent functions. If a device malfunctions, it can be replaced individually, thus achieving rapid replacement and maintenance. In particular, the locking strip of the dispensing and retrieval device engages with the slot on the hopper, using locking screws and locking holes to fix the two components in place, enabling quick assembly, disassembly, and positioning of the dispensing and retrieval device.
[0019] 5. Good sealing: The unit medicine cabinet is an independent space, and all seams are sealed. The opening and closing interfaces of frequently opened devices such as the medicine door, front door, back door, and top cover are all sealed with rubber strips, making the unit medicine cabinet a closed space with a good mosquito and insect prevention effect.
[0020] 6. Precise Dispensing: The dispensing device uses a specially designed composite conveyor belt. Through careful design of the belt's width, the height and size of the steel teeth, and the action of a shearing mechanism and an elastic pressing mechanism, difficult-to-separate medicinal materials are separated and smoothly dropped into the weighing pan, thus achieving accurate dispensing. The elastic pressing mechanism can be adjusted vertically according to the quantity of medicinal materials at the dispensing port, effectively compressing the materials.
[0021] 7. Fast dispensing speed: The entire herb-dispensing and material-shaving device may seem complex, but it works closely together, is fast and efficient, and can meet the purpose of quickly picking up medicinal materials and slices.
[0022] 8. Eliminate material bridging: Under the action of its own weight and counterweight, the pressure plate mechanism compacts the loose medicinal materials, causing the medicinal materials to slide down in the hopper as they are removed, thus avoiding the phenomenon of empty bridges in the medicinal materials.
[0023] 9. Self-cleaning capability: The inside of the bottom-discharge medicine-collecting device is designed with a cleaning scraper, which can sweep the medicine residue and dust adhering to the inside of the composite tape through the residue inlet into the residue cover, and finally accumulate in the residue bag. Only periodic cleaning of the residue in the residue bag is required.
[0024] 10. Excellent heat dissipation: The front door of the cabinet has ventilation mesh holes corresponding to the control panel, ensuring heat dissipation of the control panel; the rear of the cabinet has air intake mesh holes with dustproof mesh, and the front of the cabinet has heat dissipation exhaust mesh holes with exhaust fans installed on the mesh holes. When the exhaust fan is running, fresh air enters from the rear air intake mesh holes of the cabinet, carrying away the heat generated by the intermediate motor, and then the hot air is exhausted by the exhaust fan, thereby achieving the purpose of heat dissipation.
[0025] 11. The operating status of the unit medicine cabinet is obvious: the operating status of the unit medicine cabinet can be judged by observing the color of the medicine shortage indicator and the fault indicator on the front door of the cabinet.
[0026] 12. Advantages of modular unit medicine cabinets: Modular unit medicine cabinets separate the hopper from the cabinet body. The hopper positioning pins on the hopper match the hopper positioning slots on the cabinet body for positioning and assembly, and are then secured to the hopper via fixing holes on the cabinet body. Therefore, the hopper and cabinet body are easy to assemble and disassemble, allowing for easy replacement of other types of hoppers without changing the cabinet body.
[0027] 13. Preventing spillage during drug addition: Side baffles are installed on both sides of the drug addition door to prevent medicinal materials from accidentally falling outside the hopper during the drug addition process; the side baffles of the drug addition door are inserted into the side baffle box of the drug addition door, and a sealing brush strip is installed inside the side baffle box to prevent medicinal materials from accidentally falling into the side baffle box.
[0028] 14. Prevention of contamination: The control panel is covered with a control panel box, which isolates the control panel from the internal space of the cabinet, preventing the dust from the medicine inside the cabinet from contaminating the control panel. Some unit medicine cabinets may generate a lot of medicine dust during the dispensing process, which may contaminate the inside of the unit medicine cabinet. To prevent this dust contamination, a dustproof isolation panel (or dustproof isolation mesh) can be installed to divide the inside of the cabinet into two areas: the upper area is the heat dissipation area and the lower area is the medicine dispensing area. This reduces the space for medicine dust contamination. The two areas are isolated from each other and do not affect each other. The medicine dust generated in the dispensing area, which generates more medicine dust, will not contaminate the heat dissipation area. The dispensing area should be cleaned regularly during use.
[0029] 15. Manual unlocking: The electric locks of the cabinet front door and the dosing door are designed with a manual mechanical unlocking part. In the event of failure of the electric lock, the cabinet front door and the dosing door can be opened manually.
[0030] 16. Periodic calibration of measurement error: A calibration device is installed above the corresponding metering push-turn device in the unit medicine cabinet. The upper-level system can periodically control the calibration device through the unit medicine cabinet control board driver to calibrate the metering accuracy of the metering push-turn device, thereby ensuring the metering accuracy of the metering push-turn device.
[0031] 17. Sealing of the hopper: When the pressure plate mechanism moves up and down, the sealing steel strip moves up and down with the pressure plate mechanism, and the steel strip pressure plate always presses down on the sealing steel strip, so that the sealing steel strip covers the strip groove of the hopper and achieves the function of sealing the hopper.
[0032] 18. Suitable for different types of medicinal materials: The composite conveyor belt type bottom discharge unit for bulk Chinese medicinal materials is suitable for lightweight medicinal materials that are prone to clumping together and have some entanglement between individual pieces, such as chrysanthemum and inula.

[0098] Figure 22 The illustration shows a composite conveyor belt type bottom discharge unit cabinet for bulk Chinese herbal medicine slices. The unit cabinet consists of a cabinet box 1 and a hopper assembly. The hopper assembly is formed by an integrated hopper 5 and a top cover 7. The rectangular top cover is fastened to the upper end face of the top opening of the cabinet box. The hopper extends into the inner cavity of the cabinet box. The medicine addition port at the front of the top cover is hinged with a medicine addition door 8 with side baffles 26 on both sides. A baffle box 9 is fixed on the left and right inner side walls of the medicine addition port of the top cover for inserting the side baffles of the medicine addition door when closing the medicine addition door. The front door 13 is set at the front of the cabinet box via a door hinge 19, and the rear door for dispensing medicine is set on the rear panel of the cabinet box. The hopper rear plate is an inclined plate. Upper rollers 50a and lower rollers 50b are respectively installed on the outer walls above and below the strip groove 5b of the hopper rear plate. An annular steel strip 50c, used for sealing the strip groove, is threaded onto the upper and lower rollers. The hinge pressure plate assembly 800 has the following structure: multiple pressure rods 802 are fixed longitudinally and at equal intervals to a horizontal bar. Each pressure rod has a hinged pressure plate 803 installed at its front end via a torsion spring 804. A counterweight 805 is laterally fixed to the rear of all pressure rods. When not subjected to external force, the hinged pressure plates of all pressure rods are held in place by the torsion springs. When force is applied, an integral pressure plate is formed that is adjacent to each other. A fixed seat 801 is fixedly connected to the longitudinal fixed shaft in the middle of the horizontal bar for use as a bolt connection with the lifting mechanism. A lowering limit switch 709 and a lifting limit switch 710 are installed on the fixed seat. A clamping mechanism for the gripping disc 706 to grip is vertically arranged on the horizontal plate of the fixed seat. A frustum 707 and a disc are respectively located at the upper and lower ends of the central shaft of the clamping fixed shaft 722. An inverted frustum 708, which is symmetrical to the shape of the frustum, is a movable clamping shaft 723 that is movably fitted on the central shaft. The longitudinal fixed shaft of the aforementioned hinge pressure plate assembly 800 extends into the inner cavity of the hopper through a through hole 50d in the annular steel strip and the strip groove 5b of the hopper. Only the fixing block 801 and the snap-fit mechanism of the hinge pressure plate assembly are located on the outside of the hopper. A hinged retractable frame 806 is installed on the upper part of the rear wall of the hopper cavity; The lifting mechanism 700 used for gripping the hinge plate assembly has the following structure: a slide rail 703 is fixed to the outer wall of the hopper rear plate parallel to the hopper groove; a slider 702 is slidably mounted on the slide rail; a fixing seat 801 of the hinge plate assembly is fixedly connected to the slider; a lead screw 704 is mounted on the outer wall of the hopper rear plate parallel to the slide rail via an upper bearing seat 713 and a lower bearing seat 714; a driven gear 716 is mounted on the outer end of the lead screw extending from the lower bearing seat 714; a drive gear 715 mounted on the shaft of a reduction motor 712 mounted on the lower bearing seat meshes with the driven gear; a nut 705 is screwed onto the lead screw; a gripping disc 706 is fixed to the nut; multiple gripping disc pins 721 for mounting springs 718 are respectively set in openings on the side wall of the gripping disc; and a spring cover 719 is used to seal them. On the opening, the clamping screw 720 is screwed onto the gripping plate nail and pressed onto the spring cover. When the geared motor drives the gripping plate to move downward, the truncated cone 707 of the locking mechanism overcomes the spring force and causes the gripping plate nail 721 to extend outward, thereby causing the cone to move upward and enter the upper chamber of the gripping plate. At the same time, the gripping plate touches the lifting limit switch and causes the geared motor to stop rotating. The turntable nail returns to its original shape under the action of the spring force, and the cone is pressed against the gripping plate nail, thereby realizing the gripping action of the gripping plate. After the gripping action is completed, when the gripping plate continues to move downward under the drive of the geared motor, the inverted cone 708 located in the lower chamber of the gripping plate moves upward and squeezes the gripping plate nail into the upper chamber of the gripping plate, and finally causes the entire locking mechanism to disengage from the upper chamber of the gripping plate, thereby completing the release action of the gripping plate. Figures 36-39 This demonstrates the detailed process of the lifting mechanism grabbing the plate: 1. In the lifting device, the gripper plate moves downward, and the clamping shaft 722 (i.e., the frustum 707, which is a truncated cone at the top and a disc at the bottom) passes into the hole below the gripper plate. Figure 36 ); 2. As the gripper plate continues to move downwards, the inclined surface on the locking shaft compresses the gripper plate pins outwards, causing the gripper plate pins to compress the springs. Figure 37 ); 3. The gripper plate continues to move downwards until the inclined surface of the clamping shaft has completely passed the upper end of the gripper plate pin, at which point the spring and gripper plate pin return to their original positions. At this point, the gripper plate can lift the fixed shaft, achieving the gripping effect. The lower edge of the gripper plate then touches the lifting limit switch. Figure 38 ; 4. The gripping plate and pressure plate mechanism move upwards together. Figure 39 ).
[0099] Figures 42-46 The detailed process of the lifting mechanism lowering the plate is shown: 1. Initial state ( Figure 42 ); 2. As the gripper plate continues to move downwards, the movable shaft 723 (i.e., the inverted frustum) squeezes the gripper plate pin, causing the gripper plate pin to move outwards and compress the spring of the gripper plate pin. Figure 43 ).
[0100] 3. Figure 44 The gripper plate continues to move downwards. After the upper surface of the gripper plate pin passes the upper surface of the bayonet movable shaft, the spring and gripper plate pin return to their original positions. At this time, the upper edge of the gripper plate touches the lowering limit switch. Figure 47 ).
[0101] 4. As the gripper plate continues to move upward, the gripper plate pin lifts the movable shaft of the latch and moves it upward. After the movable shaft of the latch is in contact with the fixed shaft of the latch, it continues to move upward, causing the gripper plate pin to move outward and compress the spring of the gripper plate pin. Figure 45 ).
[0102] 5. After the gripper pin passes the lower end face of the bayonet fixing shaft, the gripper plate disengages from the bayonet shaft, achieving the effect of lowering; for example... Figure 46 .
[0103] The gripper plate continues to move upward, the gripper plate pin lifts the jaw movable shaft and moves it upward. The bottom discharge and medicine collection device 200 is fixed to the opening of the horizontal bottom plate of the hopper 5 by being embedded in the slot 49 of the hopper by the locking strip 2027.

One end of the connecting rod 39 is hinged to the toggle plate, and the other end of the connecting rod is hinged to the upper sealing plate.
[0112] When the control system controls the rear door to open, the motor drives the actuation disc to rotate. The actuation disc drives the connecting rod to push outward, which in turn pushes the upper and lower rear door sealing plates open. After opening to a certain angle, the actuation disc touches the rear door limit sensor, and the motor stops rotating. At this time, the rear door is in the open state. When the control system controls the rear door to close, the motor drives the actuation disc to rotate backward, which in turn pulls the connecting rod inward. The connecting rod pushes the upper and lower rear door sealing plates close, and the lower and upper rear door sealing plates close. The actuation disc touches the rear door reset sensor, and the motor stops rotating.
[0113] A calibration method for the aforementioned calibration device includes the following steps: (1) The control system issues a "metering calibration" command; (2) The unit medicine cabinet control board controls the metering push and flipping device to zero the weighing pan metering; (3) The unit medicine cabinet control board controls the motor of the metering calibration device to work, driving the spring wire winding bar and the weight wire winding device to rotate; (4) The weight wire reel releases the weight wire and gently lowers the weight. At the same time, the weight releases the reset touch switch, and the unit medicine cabinet control board detects that the weight has been activated. (5) At the same time as the weights move, the winding bar of the mainspring coils the mainspring, pulls the mainspring out of the mainspring coil, turns it through the pulley, passes through the small hole at one end of the spring plate, and winds it into the groove of the winding bar of the mainspring coil. (6) The weight continues to descend until it falls into the weighing pan of the metering push and flipping device. The weight is no longer under any tension. The motor continues to work for a certain period of time and then stops. The weight wire winder continues to rotate for a certain period of time to release more weight wire, so that the extra weight wire is suspended in the air and does not affect the accuracy of the weight. The length of "the motor continues to work for a certain period of time" is controlled by the positioning section on the spring wire and needs to be set in advance. (7) After the weight falls into the weighing pan of the metering push and flipping device, the positioning joint fixed on the spring line passes through the pulley and reaches the spring plate. Since the positioning joint is larger than the small hole of the spring plate, the spring line continues to be wound up, which will push the spring plate. The spring plate will press the weight into place and touch the switch. The unit medicine cabinet control board detects that the weight has reached the predetermined position and controls the motor to stop rotating. (8) When the weight specified by the metering calibration device falls into the weighing pan of the metering push-turn device, the metering device will read the measurement data of the weight in the weighing pan and send it to the unit medicine cabinet control board. The unit medicine cabinet control board will compare the measurement data with the weight data of the weight that has been entered in advance. If the comparison error is within the specified error range, the metering device is deemed to be qualified. If the comparison error exceeds the specified error range, the metering device is deemed to be unqualified. The unit medicine cabinet control board will alarm the upper-level system and prompt that the metering device in the metering push-turn device needs to be replaced. (9) After the automatic measurement and calibration of the control metering push device is completed, the control motor is reversed. The weight wire winder winds up the weight wire and lifts the weight. The spring wire winder releases the spring wire. The spring wire is pulled by the spring wire and wound into the spring coil. The positioning joint goes back with the spring wire. The spring plate rebounds and releases the weight into place and touches the switch. The control system detects that the weight has started to return. (10) The weight continues to rise and enters the weight reset fixing seat. The weight is fixed and the lever of the weight reset touch switch is pressed. The system detects that the weight has reached the initial fixed position and controls the motor to stop rotating. (11) Measurement calibration completed.
[0114] A control method for the metering push-flipping device includes the following steps: (1) Before weighing, the measurement data on the control circuit board of the electronic scale in the upper system is reset to zero. (2) The weighing pan receives the medicinal materials and processed medicinal slices output by the medicine dispensing device; (3) The electronic scale sensor under the weighing pan detects the weight of the medicinal materials in the weighing pan in real time and uploads the weight data to the upper system through the electronic scale control circuit board in real time. (4) Once the weight of the medicinal materials reaches the required weight, the material taking device stops taking out the material, and the metering, pushing and turning equipment waits for the next action instruction. (5) When the metering push-turning device receives the tilting command from the upper system, the motor of the metering push-turning device drives the lead screw to rotate, which pushes the T-flange nut to move. The T-flange nut drives the slider to move linearly on the slide rail. The slider is connected to the weighing pan rotating plate. The slider drives the weighing pan rotating plate to move linearly, thereby driving the weighing pan to move linearly. When the weighing pan moves to a certain position, the gear and rack on the weighing pan rotating plate mesh, so that the weighing pan has a turning motion on the basis of linear motion. When the weighing pan moves linearly to the designated position, the limit lever touches the limit touch switch and stops moving. At this time, the turning motion of the weighing pan just turns the weighing pan to a certain angle, so that the medicinal materials in the weighing pan are tilted out, and the medicine is discharged. After the weighing pan stays in the tilting state for a few seconds, the motor rotates in the opposite direction, driving the weighing pan to rotate back to the horizontal state and then move linearly back to the initial starting point. The motor stops moving after the limit lever touches the reset touch switch. (6) The weighing pan is reset and the weighing is zeroed, waiting for the next operation.
[0115] Figure 18 , Figure 19 In the middle, the control panel is covered with a control panel box, which isolates the control panel from the internal space of the cabinet and prevents the dust from the medicine inside the cabinet from contaminating the control panel. Some unit medicine cabinets may generate a lot of medicine dust during the dispensing process of the medicines and decoction pieces, which may contaminate the inside of the unit medicine cabinet. To prevent this dust contamination, a dustproof isolation panel (or dustproof isolation mesh) can be installed to divide the inside of the cabinet into two areas: the upper area is the heat dissipation area and the lower area is the medicine dispensing area. This reduces the space for medicine dust contamination. The two areas are isolated from each other and do not affect each other. The medicine dust generated in the dispensing area, which generates more medicine dust, will not contaminate the heat dissipation area. The dispensing area should be cleaned regularly during use.
[0116] The front door of the cabinet has ventilation mesh holes corresponding to the control panel to ensure heat dissipation of the control panel; the rear of the cabinet has air intake mesh holes with dustproof mesh, and the front of the cabinet has heat dissipation exhaust mesh holes with exhaust fans installed on the mesh holes. When the exhaust fan is running, fresh air enters from the rear air intake mesh holes of the cabinet, carrying away the heat generated by the intermediate motor, and then the hot air is exhausted by the exhaust fan, thereby achieving the purpose of heat dissipation.
[0117] Work process: Adding medication: 1. The control board receives a command from the upper-level system requesting the unlocking of the dosing door. 2. The control board driver program controls the rotation of the geared motor in the lifting mechanism, which drives the lead screw to rotate via gears. The lead screw pushes the gripper plate fixed on the lead screw nut to move downwards. When the gripper plate moves downwards and passes through the gripper plate fixing tower cap (i.e., the frustum 707), it touches the lifting limit switch. The control board driver program then controls the geared motor to stop rotating, and the gripper plate stops moving downwards. At this time, the gripper plate pin pops out under the action of the gripper plate spring, locking the gripper plate fixing tower cap. Thus, the gripping action of the gripper plate is completed.
[0118] 3. After the grabbing disc completes the grabbing action, the control board driver program controls the reduction motor in the lifting mechanism to start rotating in the opposite direction immediately. The grabbing disc moves upward, driving the pressure plate mechanism to move upward together, and driving the sealing steel belt to rotate in the opposite direction to ensure the sealing of the hopper.
[0119] 4. When the pressure plate mechanism is raised to the top of the hopper, the hinge pressure plate in the pressure plate mechanism enters the hinge retracting frame and the hinge pressure plate retracts. At this time, the grab plate touches the limit switch of the lifting mechanism, and the control board driver controls the reduction motor to stop moving, and the lifting mechanism and the pressure plate mechanism stop rising.
[0120] 5. The control board driver program controls the electric lock of the dosing door to be powered on and unlocked. The dosing door automatically pops open under the action of the spring plate and remains open.
[0121] 6. The user loads the medicinal herbs into the hopper.
[0122] 7. The user manually closes the dosing door.
[0123] 8. The geared motor of the lifting mechanism rotates, the gripper moves downward, and the pressure plate mechanism moves downward under its own weight and the action of the gripper. The hinge pressure plate retracts from the hinge retraction frame and unfolds into a 180° flat plate under the action of the torsion spring. As the gripper and the pressure plate mechanism continue to move downward, the hinge pressure plate contacts the top of the medicinal materials in the hopper until the entire weight of the pressure plate mechanism presses the medicinal materials. At this point, the pressure plate mechanism will no longer move downward.
[0124] After the pressure plate mechanism stops moving, the lifting mechanism continues to move downwards. The grab plate moves downwards with the lifting mechanism, passing through the movable cap (inverted frustum 708) of the grab plate. After passing through the movable cap, the grab plate touches the lowering limit switch, and the reduction motor starts to rotate in the opposite direction. The lifting mechanism begins to move upwards, and the grab plate moves upwards with the lifting mechanism, passing through the movable cap and the fixed cap, causing the grab plate to disengage from the pressure plate mechanism. This completes the grab plate release action. The lifting mechanism continues to move upwards, and the grab plate touches the lifting mechanism limit switch. The control board driver stops the reduction motor, and the lifting mechanism stops rising. The lifting mechanism then awaits the next grabbing task.
[0125] 9. The dosing operation is complete.
[0126] Pick up the medicine: 1. After receiving the medicine picking instruction from the upper-level system, the control board driver controls the metering and pushing device to start metering, the control board driver controls the lower discharge and medicine picking device to start operating, and the control board driver controls the planing mechanism to start working.
[0127] 2. The geared motor in the bottom discharge and medicine taking device drives the composite conveyor belt to rotate, and the steel nails on the composite conveyor belt carry out the medicinal materials.
[0128] 3. As the medicinal herbs are carried out, the height of the herbs in the hopper decreases. The pressure plate mechanism with counterweights also descends under its own weight, maintaining continuous pressure on the herbs. At the same time, the pressure plate mechanism drives the sealing steel belt to rotate in the forward direction, ensuring the hopper is sealed.
[0129] 4. The process of one-time herb removal and material preparation: After the composite conveyor belt rotates continuously for a specified time, the reduction motor in the herb removal device stops working under the control of the control board driver. Simultaneously, the control board driver controls the gear reduction motor in the material preparation mechanism to operate. The driving gear drives the driven gear and the cam behind the driven gear to rotate together. During the rotation of the driven gear, the cam behind the driven gear presses the upper plate of the movable pressure block downwards. The upper plate of the movable pressure block drives the movable pressure block to move downwards, pressing the herb slices in the outlet. Under the action of the cam, long spring, and short spring behind the driven wheel, the herb slices remain in a compressed state for a period of time during the rotation of the driven wheel. At the same time, the herb slices... During the compaction process, the driving gear rotates the driven gear, which in turn drives the planing gear via the synchronous pulley and belt. This planing gear, in turn, drives two planing driven gears to rotate in the same direction, simultaneously rotating the rake linkage fixed to the two planing driven gears. The rake linkage then drives the toothed rake to rotate, grabbing and planing the medicinal herbs protruding from the movable pressing block downwards and backwards, separating these herbs from the compressed herbs. (If any herbs adhere to the toothed rake during the planing process, the toothed scraper will scrape them off as the rake rotates past the toothed scraper.) The separated herbs fall through the discharge port into the weighing pan of the metering and pushing tilting device. This completes one round of herb removal and planing.
[0130] 5. After repeated processing of the medicine and material, once the required weight is reached, the metering, pushing, and turning device stops metering, the lower discharge and medicine-collecting device stops operating, and the material-shaving mechanism resets and stops working. The machine then waits for the medicine to be discharged.
[0131] Dispensing medicine: 1. After receiving the dispensing command from the upper system, the control board driver controls the motor in the rear door device to rotate outward, which in turn drives the connecting rod and sensor actuation plate to rotate outward. The connecting rod lifts the upper sealing plate of the rear door and drives the lower sealing plate of the rear door to open. When the sensor actuation plate rotates to a certain angle, it touches the rear door limit sensor, the motor stops rotating, and the rear door device remains open.
[0132] 2. While the control board driver controls the operation of the rear door device, it also controls the operation of the metering push and flipping device. The motor in the metering push and flipping device starts to rotate, pushing the weighing pan towards the rear door. After moving horizontally for a certain distance, the gears and racks on the weighing pan turn plate mesh, so that the weighing pan also has a flipping motion on the basis of horizontal movement, and begins to pour out the medicinal materials. Until the weighing pan flips to a certain angle and touches the limit switch, the motor stops rotating and the weighing pan stops flipping. At this time, the medicinal materials can be completely poured out.
[0133] 3. After the weighing pan maintains its tilt angle for a certain period of time, the control board driver program controls the motor in the metering push and flipping device to start rotating in the opposite direction. The weighing pan rotates back to a horizontal state, then moves horizontally back. After touching the limit switch, the motor stops rotating and the weighing pan resets.
[0134] 4. After the metering push flipping device is reset, the control board driver controls the motor in the rear door device to rotate inward, which in turn drives the connecting rod and sensor actuation plate to rotate inward. The connecting rod drives the upper and lower sealing plates of the rear door to rotate and close. When the sensor actuation plate rotates to a certain angle, the sensor actuation plate touches the rear door reset sensor, the motor stops rotating, and the rear door device is in the closed state.
[0135] 5. Wait for the next dose of medication.

Each of the horizontal sections at the top of the left and right side plates has a quick-locking hole (2030) for quick locking with the hopper using screws; The large square head of the steel nail has the same shape as the large square head on the lower stop strip, both being cubic; the thickness of the steel strip is 0.1mm to 2mm, and the thickness of the PU silicone layer is 1mm to 10mm; The lifting structure (700) used as the hinge clamping plate assembly is as follows: the slide rail (703) is fixed to the outer wall of the hopper rear plate parallel to the hopper slot; the slider two (702) is slidably mounted on the slide rail; the fixing seat (801) of the hinge clamping plate assembly is fixedly connected to the slider two; the lead screw (704) is mounted on the outer wall of the hopper rear plate parallel to the slide rail through the upper bearing seat (713) and the lower bearing seat (714); a driven gear (716) is mounted on the outer end of the lead screw extending from the lower bearing seat (714); the drive gear (715) mounted on the shaft of the reduction motor (712) mounted on the lower bearing seat meshes with the driven gear; the nut (705) is screwed onto the lead screw; the gripper plate (706) is fixed on the nut; and multiple gripper plate pins (721) for mounting springs (718) are respectively set in the openings on the side wall of the gripper plate. In the middle, the spring cover (719) seals the opening, and the clamping screw (720) is screwed onto the gripping plate nail and pressed onto the spring cover. When the geared motor drives the gripping plate to move downward, the truncated cone (707) of the clamping mechanism overcomes the spring force and causes the gripping plate nail (721) to extend outward, thereby causing the truncated cone to move upward and enter the upper chamber of the gripping plate. At the same time, the gripping plate touches the lifting limit switch and causes the geared motor to stop rotating. The gripping plate nail returns to its original state under the action of the spring force and is pressed under the truncated cone (707), thereby realizing the gripping action of the gripping plate. After the gripping action of the gripping plate is completed, when the gripping plate continues to move downward under the drive of the geared motor, the inverted truncated cone (708) located in the lower chamber of the gripping plate moves upward and squeezes the gripping plate nail into the upper chamber of the gripping plate, and finally causes the entire clamping mechanism to disengage from the upper chamber of the gripping plate, thereby completing the release action of the gripping plate. A main intermediate beam (2017) is fixed to the lower position of the support wheel assembly between the left and right sides of the plate by fixing screws (2022); a secondary intermediate beam (2023) is also fixed to the lower position of another support wheel between the left and right sides of the driven wheel by screws. The stainless steel nail-type composite conveyor belt (500) has the following structure: the two wide sides of the steel belt (501) are set at the same angle to the two parallel long sides, and the two wide sides are parallel to each other. Several rows of holes are evenly spaced along the long side of the steel belt, with small square holes and large square holes alternating in each row. The two wide side seams of the steel belt are aligned and laser-welded into one piece. The lower stop bar (502) has the following structure: small square holes and large square heads are evenly spaced and alternating on the surface of the plate with an arc-shaped cross-section. The bottom of the plate has one or more grooves (502a). The position of each row of holes of the steel belt is as follows: A lower baffle is provided: the large square head on the lower baffle passes through the large square hole in the row of holes on the steel belt, and the steel nail is composed of a small square head and a large square head integrated together. The small square heads of multiple steel nails (503) pass through the small square holes in the row of holes on the steel belt from top to bottom and are inserted into the small square holes on the lower baffle, and are laser welded together with the lower baffle. A PU silicone layer (504) is covered and fixed on the bottom surface of the steel belt with the lower baffle to form a composite conveyor belt. The steel belt, the lower baffle and the steel nail are all made of food-grade 304 stainless steel or food-grade 316 stainless steel. The steel strip has an odd number of holes in each row, starting with and ending with a small square hole.

8. A metering calibration method for a metering calibration device of a composite conveyor belt type lower discharge belt for bulk Chinese herbal medicine slices unit cabinet as described in any one of claims 2-7, characterized in that, Includes the following steps: (1) The control system issues a metering calibration command; (2) The unit medicine cabinet control board controls the metering push and flipping device to zero the weighing pan metering; (3) The unit medicine cabinet control board controls the motor of the metering calibration device to work, driving the spring wire winding bar and the weight wire winding device to rotate; (4) The weight wire reel releases the weight wire and gently lowers the weight. At the same time, the weight releases the reset touch switch, and the unit medicine cabinet control board detects that the weight has been activated. (5) At the same time as the weights move, the winding bar of the mainspring coils the mainspring, pulls the mainspring out of the mainspring coil, turns it through the pulley, passes through the small hole at one end of the spring plate, and winds it into the groove of the winding bar of the mainspring coil. (6) The weight continues to descend until it falls into the weighing pan of the metering push and flipping device. The weight is no longer under any tension. The motor of the metering calibration device continues to work for a certain period of time and then stops. The weight wire winder continues to rotate for a certain period of time to release more weight wire, so that the extra weight wire is suspended in the air and does not affect the accuracy of the weight. The length of time the motor continues to work is controlled by the positioning section on the spring wire and needs to be set in advance. (7) After the weight falls into the weighing pan of the metering push and flipping device, the positioning joint fixed on the spring wire passes through the pulley and reaches the spring plate. Since the positioning joint is larger than the small hole of the spring plate, the spring wire continues to be wound up, which will push the spring plate. The spring plate will press the weight into place and touch the switch. The unit medicine cabinet control board detects that the weight has reached the predetermined position and controls the motor of the metering calibration device to stop rotating. (8) When the weight specified by the metering calibration device falls into the weighing pan of the metering push-turn device, the metering device will read the measurement data of the weight in the weighing pan and send it to the unit medicine cabinet control board. The unit medicine cabinet control board will compare the measurement data with the weight data of the weight that has been entered in advance. If the comparison error is within the specified error range, the metering device is deemed to be qualified. If the comparison error exceeds the specified error range, the metering device is deemed to be unqualified. The unit medicine cabinet control board will alarm the upper-level system and prompt that the metering device in the metering push-turn device needs to be replaced. (9) After the automatic measurement and calibration of the control metering push device is completed, the control motor is reversed. The weight wire winder winds up the weight wire and lifts the weight. The spring wire winder releases the spring wire. The spring wire is pulled by the spring wire and wound into the spring coil. The positioning joint goes back with the spring wire. The spring plate rebounds and releases the weight into place and touches the switch. The control system detects that the weight has started to return. (10) The weight continues to rise and enters the weight reset fixing seat. The weight is fixed and the lever of the weight reset touch switch is pressed. The system detects that the weight has reached the initial fixed position and controls the motor of the metering calibration device to stop rotating. (11) Measurement calibration completed.
9. A control method for the metering, pushing, and flipping device of the composite conveyor belt type bottom discharge belt for bulk Chinese herbal medicine slices unit cabinet as described in any one of claims 1-7, characterized in that, Includes the following steps: (1) Before weighing, the measurement data on the control circuit board of the electronic scale in the upper system is reset to zero. (2) The weighing pan in the metering push-turning device receives the medicinal materials and decoction pieces output by the medicine dispensing device; (3) The electronic scale sensor under the weighing pan detects the weight of the medicinal materials in the weighing pan in real time and uploads the weight data to the upper system through the electronic scale control circuit board in real time. (4) Once the weight of the medicinal materials reaches the required weight, the material taking device stops taking out the material, and the metering, pushing and turning equipment waits for the next action instruction. (5) When the metering push-turning device receives the tilting command from the upper system, the motor of the metering push-turning device drives the lead screw to rotate, which pushes the T-flange nut to move. The T-flange nut drives the slider one to move linearly on the slide rail. The slider one is connected to the weighing pan rotating plate. The slider one drives the weighing pan rotating plate to move linearly, thereby driving the weighing pan to move linearly. When the weighing pan moves to a certain position, the gear and rack on the weighing pan rotating plate mesh, so that the weighing pan has a turning motion on the basis of linear motion. When the weighing pan moves linearly to the designated position, the limit lever touches the limit touch switch and stops moving. At this time, the turning motion of the weighing pan just turns the weighing pan to a certain angle, so that the medicinal materials in the weighing pan are tilted out, and the medicine is discharged. After the weighing pan stays in the tilting state for a few seconds, the motor rotates in the opposite direction, driving the weighing pan to rotate back to the horizontal state and then move linearly back to the initial starting point. The motor stops moving after the limit lever touches the reset touch switch. (6) The weighing pan is reset and the weighing is zeroed, waiting for the next operation.
10. A control method for a control board of a medicine cabinet for a composite conveyor belt type bottom discharge bulk Chinese herbal medicine slice unit as described in any one of claims 1 to 9, characterized in that, Includes the following steps: Adding medication: (1) The control board receives a command from the upper-level system requesting the unlocking of the dosing door. (2) The control board driver controls the speed reduction motor of the metering push and flipping device in the lifting mechanism to rotate, and drives the screw to rotate through the gear. The screw pushes the gripper fixed on the screw nut to move downward. When the gripper moves downward to pass through the gripper fixing tower cap, i.e., the truncated cone (707), it touches the lifting limit switch. The control board driver controls the speed reduction motor to stop rotating, and the gripper stops moving downward. At this time, the gripper pin pops out under the action of the gripper spring and locks the gripper fixing tower cap. Thus, the gripping action of the gripper is completed. (3) After the grabbing disc completes the grabbing action, the control board driver controls the reduction motor in the lifting mechanism to start rotating in the opposite direction immediately, the grabbing disc moves upward, and at the same time drives the pressure plate mechanism to move upward, and drives the sealing steel belt to rotate in the opposite direction to ensure the sealing of the hopper. (4) When the pressure plate mechanism is lifted to the top of the hopper, the hinge pressure plate in the pressure plate mechanism enters the hinge retracting frame and the hinge pressure plate retracts. At this time, the grab plate touches the limit switch of the lifting mechanism, and the control board driver controls the reduction motor to stop moving, and the lifting mechanism and the pressure plate mechanism stop rising. (5) The control board driver program controls the electric lock of the dosing door to be powered on and unlocked. The dosing door automatically pops up and opens under the action of the spring plate and remains open. (6) The user loads the medicinal herbs into the hopper; (7) The user manually closes the dosing door; (8) The geared motor of the lifting mechanism rotates, the grab plate moves downward, and the pressure plate mechanism moves downward under its own weight and the action of the grab plate. The hinge pressure plate exits the hinge retractor and unfolds into a 180° flat plate under the action of the torsion spring. As the grab plate and the pressure plate mechanism continue to move downward, the hinge pressure plate contacts the top of the medicinal materials in the hopper until the entire weight of the pressure plate mechanism presses the medicinal materials. At this time, the pressure plate mechanism will no longer move downward. After the pressure plate mechanism stops moving, the lifting mechanism continues to move downwards. The grab plate moves downwards with the lifting mechanism, passing through the movable cap of the grab plate, i.e., the inverted truncated cone (708). After passing through the movable cap of the grab plate, the grab plate touches the lowering limit switch, and the reduction motor starts to rotate in the opposite direction. The lifting mechanism starts to move upwards, and the grab plate moves upwards with the lifting mechanism, passing through the movable cap of the grab plate and the fixed cap of the grab plate, causing the grab plate of the lifting mechanism to disengage from the pressure plate mechanism. At this point, the release action of the grab plate is completed. The lifting mechanism continues to move upwards, and the grab plate touches the lifting mechanism limit switch. The control board driver program controls the reduction motor to stop moving, and the lifting mechanism stops rising. The lifting mechanism waits for the next grabbing task. (9) The dosing work is completed; Pick up the medicine: (1) After the control board receives the medicine picking instruction from the upper system, the control board driver controls the metering and pushing device to start metering, the control board driver controls the lower discharge medicine picking device to start operating, and the control board driver controls the planing mechanism to start working. (2) The speed reduction motor in the lower discharge and medicine taking device drives the composite conveyor belt to rotate, and the steel nails on the composite conveyor belt carry out the medicinal materials; (3) As the medicinal materials are carried out, the height of the medicinal materials in the hopper decreases, and the pressure plate mechanism with counterweight also decreases under its own weight, maintaining continuous pressure on the medicinal materials; at the same time, the pressure plate mechanism drives the sealing steel belt to rotate in the positive direction to ensure the hopper is sealed. (4) The process of one-time medicine taking and cutting: After the composite conveyor belt rotates continuously for a specified time, the reduction motor in the medicine taking device under the control of the control board driver stops working; at the same time, the control board driver controls the gear reduction motor in the cutting mechanism to move, the driving gear drives the driven gear and the cam behind the driven gear to rotate together. During the rotation of the driven gear, the cam behind the driven gear presses the top plate of the movable pressure block downward, the top plate of the movable pressure block drives the movable pressure block to move downward, the movable pressure block presses the medicinal slices in the outlet tightly, and under the action of the cam, long spring and short spring behind the driven wheel, the medicinal slices are kept in a pressed state for a period of time during the rotation of the driven wheel; at the same time, during the process of the medicinal slices being pressed While the driving gear drives the driven gear to rotate, the driving gear also drives the planing driving gear to rotate via the synchronous pulley and synchronous belt. The planing driving gear drives two planing driven gears to rotate in the same direction, and at the same time drives the rake connecting rod, which is fixed to the two planing driven gears, to rotate. The rake connecting rod drives the toothed rake to rotate, grabbing and planing the medicinal materials protruding from the movable pressing block backward and downward, so that these medicinal materials are separated from the pressed medicinal materials. If medicinal materials are stuck to the toothed rake during the process of grabbing and planing, the toothed scraper will scrape off these stuck medicinal materials when the toothed rake rotates and passes through the toothed scraper. The separated medicinal materials fall into the weighing pan of the metering and pushing flipping device through the discharge port. Thus, one round of medicinal material removal and planing is completed. (5) After repeated drug taking and cutting operations, when the required weight of drugs is reached, the metering, pushing and turning device stops metering, the lower discharge drug taking device stops operating, and the cutting mechanism resets and stops working; waiting for drug to be discharged. Dispensing medicine: (1) After the control board receives the medicine dispensing command from the upper system, the control board driver controls the motor in the rear door device to rotate outward, and drives the connecting rod and sensor actuation plate to rotate outward. The connecting rod lifts the upper sealing plate of the rear door and drives the lower sealing plate of the rear door to open. When the sensor actuation plate rotates to a certain angle, the sensor actuation plate touches the rear door limit sensor, the motor stops rotating, and the rear door device remains open. (2) While the control board driver controls the operation of the rear door device, it also controls the operation of the metering push and flipping device. The motor in the metering push and flipping device starts to rotate, pushing the weighing pan to move towards the rear door. After moving horizontally for a certain distance, the gear and rack on the weighing pan turn plate mesh, so that the weighing pan has a flipping motion on the basis of horizontal movement, and begins to pour out the medicinal herbs. Until the weighing pan flips to a certain angle and touches the limit switch, the motor stops rotating and the weighing pan stops flipping. At this time, the medicinal herbs can be completely poured out. (3) After the weighing pan maintains the tilt angle for a certain period of time, the control board driver controls the motor in the metering push and flipping device to start rotating in the opposite direction. The weighing pan rotates back to the horizontal state, and then moves horizontally back. After touching the limit switch, the motor stops rotating and the weighing pan resets. (4) When the metering push flipping device is reset, the control board driver controls the motor in the rear door device to rotate inward, and drives the connecting rod and sensor toggle disc to rotate inward. The connecting rod drives the upper and lower sealing plates of the rear door to rotate and close. When the sensor toggle disc rotates to a certain angle, the sensor toggle disc touches the rear door reset sensor, the motor stops rotating, and the rear door device is in the closed state. (5) Wait for the next dose of medicine.
