Description

Technical Field

[0001] This invention relates to the field of medicinal herb processing technology, and in particular to a fully automatic drum-type stir-frying machine for medicinal herbs. Background Technology

[0002] A stir-frying machine is a specialized piece of equipment used for the stir-frying and processing of materials, particularly Chinese medicinal herbs. It's used in the early stages of processing these herbs, heating and turning them to achieve drying, ripening, aroma enhancement, and property modification. It replaces traditional manual stir-frying methods, enabling mechanized and standardized operation, significantly improving processing efficiency and quality stability.

[0003] The principle of the drum-type stir-frying machine is that the motor drives the drum connecting shaft through the speed transmission, so that the drum rotates under the support of the support roller. At the same time, the drum is heated by the electromagnetic coil or other heat sources. The rotation and heating make the material inside the drum evenly heated, thereby achieving the purpose of stir-frying. When the drum rotates, the spiral plate rotates clockwise to stir-fry the material, and the drum reverses to discharge the material.

[0004] The currently used herb-frying machines mainly operate through dynamic heating. During the heating process, they require enclosed insulation, making it inconvenient to switch states to achieve input and output through the same port, thus hindering global automated control and stable gas extraction, exhaust, and liquid addition.

[0008] Optionally, a driven gear is fixedly installed on the rear side of the central pipe at a position between the wrapper housing and the stir-frying cylinder; a gear is installed on the rotor end of the reversing motor to mesh with the driven gear.

[0009] Optionally, a trigger is fixedly installed at the rear end of the central pipe, which can trigger the proximity sensor; two sets of partitions are fixedly installed outside the central pipe, the partitions are located on both sides of the long guide hopper, and an air extraction hole is opened in the rear partition; the long guide hopper and the input hopper are staggered vertically, with the opening of the long guide hopper facing upward and the opening of the input hopper facing downward; the rear partition is aligned with the middle of both sides of the stir-frying cylinder, and the rear partition does not contact the stir-frying cylinder.

[0010] Optionally, a heat insulation ring is fixedly provided at the rear end of the stir-frying cylinder, and a stir-frying gear ring is fixedly provided at the rear end of the heat insulation ring; a stir-frying motor is fixedly provided at the lower rear of the rear support frame, and a gear is provided at the rotor end of the stir-frying motor to mesh with the stir-frying gear ring.

[0012] Optionally, two sets of docking telescopic cylinders are fixedly installed on the rear side of the inner side of the wrapping machine housing, and the telescopic ends of the two sets of docking telescopic cylinders are respectively fixed on both sides of the rear end of the docking ring; when the two sets of docking telescopic cylinders are extended, the docking ring is fastened to the rear outside of the air extraction hole; and air intake grooves are opened on both sides of the lower part of the wrapping machine housing.

[0016] This invention solves the problems of dynamic heating and heat insulation in traditional herbal stir-frying machines, and the difficulty in simultaneously handling input and output at the same port. By using a reversing motor to drive the central pipe to rotate, and with the precise positioning of sensors, the port states of the input hopper and the long guide hopper can be switched. No manual intervention is required, and it works in conjunction with conveying, stir-frying and other processes to achieve global automation while ensuring heating and sealing, thus improving the continuity of operation.

[0017] This invention solves the problem that some medicines require the addition of additives during stir-frying and that the liquid addition is unstable in a dynamic heating and closed environment. It retains the function of adding additives through the dosing tube and can stably add liquid in a dynamic heating and closed environment. The equipment structure can be matched with different production scenarios, whether it is conventional stir-frying, processing that requires the addition of additives, or production of different scales, and can cope with them, thus enhancing the adaptability to various scenarios.

[0018] This invention solves the problem of pressure imbalance caused by exhaust in traditional herbal stir-frying machines under closed heating conditions. During the stir-frying process, the exhaust fan continuously draws out the fumes from the stir-frying cylinder and discharges them efficiently through the exhaust pipe, preventing fumes from lingering and affecting the processing environment. The openings on both sides of the machine casing naturally introduce air, achieving air circulation. The air first provides sufficient oxygen to the long-row gas stove to ensure stable and efficient heating, and then replenishes the inside of the stir-frying cylinder to maintain its internal and external pressure balance, thereby ensuring the quality of the stir-fried herbs.

[0030] Example 1: Please refer to the accompanying drawings in the instruction manual. Figures 1 to 8 As shown:

[0031] This invention proposes a fully automatic drum-type herbal stir-frying machine, comprising: a base plate 1, with a casing 2 fixedly mounted on the top of the base plate 1; two sets of supporting rotating frames 3 fixedly mounted on both sides of the top of the base plate 1, with the casing 2 fitting snugly around the outside of the supporting rotating frames 3; four sets of bearing frames 101 fixedly mounted on the top of the base plate 1 and the inside of the casing 2, with T-shaped bearing wheels 102 rotatably mounted on adjacent surfaces of the front and rear bearing frames 101; a central pipe 4 rotatably mounted between the two sets of supporting rotating frames 3 with a bearing; a stir-frying cylinder 5, with inwardly curved annular baffles on both sides of the stir-frying cylinder 5; and stir-frying plates 501 fixedly mounted at equal intervals on the inner arc surface of the stir-frying cylinder 5. The stir-frying cylinder 5 is set at an angle; the outside of the stir-frying cylinder 5 is attached between the upper, lower, front and rear sets of T-shaped support wheels 102; two sets of long-row gas stoves 6 are fixedly installed on the top of the bottom plate 1, and the two sets of long-row gas stoves 6 are connected to the gas source by pipes; the burners of the long-row gas stoves 6 are aligned with the bottom of the stir-frying cylinder 5; a long-row guide bucket 401 is integrally installed in the position of the central pipe 4 inside the stir-frying cylinder 5, and a spiral propeller 402 is rotatably installed in the middle of the central pipe 4; a conveying motor 403 is fixedly installed at the front end of the central pipe 4, and the conveying motor 403 is connected to the spiral propeller 402 for transmission; an input bucket 404 is integrally installed at the front end of the central pipe 4 outside the casing 2.

[0032] Among them, a motor frame 301 is fixedly installed on the rear external side of the rear support frame 3, and a reversing motor 302 is fixedly installed on the external side of the motor frame 301; a proximity sensor 303 is fixedly installed on the top of the motor frame 301.

[0033] Among them, a driven gear 405 is fixedly installed on the rear side of the central pipe 4 at the position between the wrapper shell 2 and the stir-frying cylinder 5; a gear is installed on the rotor end of the reversing motor 302 to mesh with the driven gear 405.

[0034] The central pipe 4 is fixedly equipped with a trigger 406 at its rear end, which can trigger the proximity sensor 303. Two sets of partitions 407 are fixedly installed outside the central pipe 4. The partitions 407 are located on both sides of the long guide bucket 401, and the rear partition 407 has an air extraction hole 408. The long guide bucket 401 and the input bucket 404 are staggered, with the opening of the long guide bucket 401 facing upward and the opening of the input bucket 404 facing downward. The rear partition 407 is aligned with the middle of both sides of the stir-frying cylinder 5, and the rear partition 407 does not contact the stir-frying cylinder 5.

[0035] Among them, a heat insulation ring 502 is fixedly installed at the rear end of the stir-frying cylinder 5, and a stir-frying gear ring 503 is fixedly installed at the rear end of the heat insulation ring 502; a stir-frying motor 8 is fixedly installed at the lower rear of the rear support frame 3, and a gear is provided at the rotor end of the stir-frying motor 8 to mesh with the stir-frying gear ring 503.

[0036] Among them, an exhaust device 7 is fixedly installed on the upper rear side of the packaging shell 2, and an exhaust fan 701 driven by a motor is mounted in the middle of the exhaust device 7; a corrugated pipe 702 is fixedly installed at the front end of the exhaust device 7, and a docking ring 703 is fixedly installed at the front end of the corrugated pipe 702; and an exhaust pipe 704 is fixedly installed at the rear end of the exhaust device 7.

[0037] The packaging machine housing 2 has two sets of docking telescopic cylinders 201 fixedly installed on the rear side inside. The telescopic ends of the two sets of docking telescopic cylinders 201 are respectively fixed on both sides of the rear end of the docking ring 703. When the two sets of docking telescopic cylinders 201 are extended, the docking ring 703 is fastened to the rear outside of the air extraction hole 408. Air intake slots are opened on both sides of the lower part of the packaging machine housing 2.

[0038] The inside of the packaging machine housing 2 is fixedly equipped with a dosing pipe 9, which passes through the gap between the partition 407 and the stirring cylinder 5; side nozzles 901 are fixedly installed on both sides of the dosing pipe 9, and an external pipe is fixedly connected to the front end of the dosing pipe 9.

[0039] Among them, the commutator motor 302, the conveyor motor 403 and the stir-fry motor 8 are all servo motors capable of controlling forward and reverse rotation.

[0040] Drug administration procedure:

[0041] Staff press Figure 3 The handheld medicine box is in a state of continuous medicine feeding from input hopper 404, and the medicine will enter the central pipe 4;

[0042] Start the conveyor motor 403, which will drive the screw propeller 402 to rotate. With the rotational force of the screw propeller 402, the medicine will be continuously conveyed backward and finally discharged from the long guide bucket 401. The medicine will continuously fall into the stir-frying cylinder 5 to complete the drug delivery.

[0043] After the medication is dispensed, place the medicine box under the input hopper 404.

[0044] Stir-frying process:

[0045] Start the stir-frying motor 8 to drive the stir-frying gear ring 503 to rotate. When the stir-frying gear ring 503 rotates, it will drive the stir-frying cylinder 5 to rotate synchronously. At the same time, the long-row gas stove 6 is ignited to continuously heat the stir-frying cylinder 5, so as to stir-fry the medicine.

[0046] When the stirring cylinder 5 rotates, the medicine is moved by the obtuse angle side of the stirring plate 501. Since the medicine is easy to fall off the plate when the obtuse angle side is pushed, a continuous stirring effect is formed.

[0047] If additives (such as alcohol, rice wine, alkaline water, plant essential oil, etc.) need to be added when stir-frying medicines, the dosing tube 9 can be connected to the additive source in advance. During the stir-frying process, the medicine liquid is introduced through the dosing tube 9 and sprayed out from the side nozzle 901 to complete the dosing operation.

[0048] Therefore, the herb-frying machine can be adapted to the production needs of different types of medicines and meet the usage scenarios of different production workshops or manufacturers.

[0049] Fume treatment and air circulation:

[0050] During the stir-frying process, the exhaust fan 701 is activated to draw air from inside the stir-frying cylinder 5, while oil fumes and other substances are continuously discharged from the exhaust pipe 704.

[0051] The openings on the lower sides of the casing 2 are air intake channels: after air enters through the openings, it first contacts the long-row gas stove 6 to ensure combustion oxygen supply, and then replenishes the inside of the stirring cylinder 5 to maintain the internal pressure balance of the equipment.

[0052] Automatic medicine collection operation:

[0053] After stir-frying, retract the telescopic cylinder 201 to disengage the docking ring 703 from the vent 408; start the reversing motor 302 to drive the driven gear 405 to rotate half a turn, and the central pipe 4 will rotate half a turn accordingly (e.g., Figure 4 (Status), at this time the opening of the long guide bucket 401 is facing upwards, and the opening of the input bucket 404 is facing downwards;

[0054] The reverse stirring motor 8 drives the stirring gear ring 503 and the stirring cylinder 5 to reverse: at this time, the acute angle side of the stirring plate 501 moves the medicine. Only when the stirring plate 501 rises to the height of the stirring cylinder 5 will the medicine fall and fall into the long guide bucket 401.

[0055] The reverse conveyor motor 403 drives the screw propeller 402 to rotate in the opposite direction, generating a forward conveying force. The medicine is discharged through the input hopper 404 and falls naturally into the medicine box placed below, completing the automatic collection.

[0056] The proximity sensor 303 works in conjunction with the trigger 406 to provide a positioning function and precisely control the position adjustment of the central pipe 4.

[0057] After the medicine is discharged, reverse and reset the central pipe 4, and restore all components to their initial state, and then proceed with the next round of medicine frying.

[0058] The above process, through the coordinated operation of various components of the equipment, achieves automated operation from drug administration, stirring, adding drugs to drug collection, while taking into account the processing needs of different drugs and operational safety.

[0059] Example 2: Based on Example 1, the specific type of the docking telescopic cylinder 201 can be selected according to actual needs. Electric cylinders, electric push rods, pneumatic cylinders, hydraulic cylinders, or any other actuators with the same function can be used to achieve the docking effect. It can be selected and used interchangeably according to the workshop environment. For example, if there is a compressed air pipeline in the workshop, a pneumatic cylinder can be used directly, and if there is only an electrical circuit, an electric cylinder can be used.

[0060] Example 3: Based on Example 1, two sets of long-row gas stoves 6 are equipped with gas pipes connected to the outside and use gas heating. The long-row gas stoves 6 only provide heating effect and can be replaced as needed.

[0061] The long-row gas stove 6 can be disassembled and replaced with a resistance heater, solar heater, or waste heat utilization equipment, etc., for stir-frying medicinal herbs.

[0062] The specific usage and function of this embodiment: In this invention, when used, according to... Figure 3 In this state, the staff holds the medicine box and continuously feeds the medicine into the input hopper 404, where it enters the central pipe 4. The conveyor motor 403 is started to drive the screw propeller 402 to rotate, and the screw propeller 402 continuously conveys the medicine backward, which is discharged from the long guide hopper 401. The medicine continuously falls into the inside of the stir-frying cylinder 5, completing the medicine feeding. Then, the medicine box is placed below the input hopper 404.

[0063] The stir-fry motor 8 is started, which drives the stir-fry gear ring 503 to rotate. During the rotation of the stir-fry gear ring 503, the stir-fry cylinder 5 rotates synchronously. At the same time, the long-row gas stove 6 is ignited to continuously heat the stir-fry cylinder 5, thus achieving stir-frying. During the rotation of the stir-fry cylinder 5, the obtuse angle side of the stir-fry plate 501 is used to move the medicine. During the movement of the stir-fry plate 501, the medicine is easily dropped, thus achieving continuous stir-frying.

[0064] Some types of medicines require the continuous or intermittent addition of additives during the stir-frying process, such as alcohol, rice wine, alkaline water, and plant essential oils. The additives are pre-connected to the dosing pipe 9. During the stir-frying process, the medicine liquid is input into the dosing pipe 9 and sprayed out from the side nozzle 901 to achieve the addition of medicines. Therefore, the stir-frying machine can be used to produce different types of medicines and can be matched with different production workshops or manufacturers.

[0065] During stir-frying, the exhaust fan 701 draws air from the inside of the stir-frying cylinder 5 and continuously discharges oil fumes and other substances from the exhaust pipe 704; the openings on both sides of the casing 2 facilitate air intake, and the air enters the inside of the casing 2 from the openings of the casing 2, first contacting the long-row gas stove 6 to ensure oxygen supply, and then replenishing the inside of the stir-frying cylinder 5 to maintain pressure balance.

[0066] After stir-frying, the retractable telescopic cylinder 201 disengages the docking ring 703 from the air extraction port 408, and the reversing motor 302 drives the driven gear 405 to rotate half a turn, thus rotating the position of the central pipe 4 half a turn. Figure 4 In this state, the opening of the long guide bucket 401 faces upward, and the opening of the input bucket 404 faces downward;

[0067] At this time, the reverse stirring motor 8 drives the stirring gear ring 503 to rotate, and the stirring cylinder 5 reverses. The acute angle side of the stirring plate 501 drives the medicine to move. When the stirring plate 501 rises to the height of the stirring cylinder 5, the medicine carried by the stirring plate 501 will fall into the long guide hopper 401. The reverse conveying motor 403 drives the screw propeller 402 to rotate, generating a forward conveying force, which discharges the medicine from the input hopper 404, allowing it to fall naturally into the medicine box for automatic collection.

[0068] The proximity sensor 303 and trigger 406 provide a positioning effect and can control the position adjustment of the central pipe 4;

[0069] After the medicine is discharged, reverse the central pipe 4 again and reset all components to allow the medicine to be stir-fried again.
