Description

Technical Field

[0001] The present invention belongs to the field of traditional Chinese medicine decocting, and specifically relates to a control method for a drum-type decocting machine. Background Art

[0002] Currently, the decocting machines on the market do not stir during the process of decocting and extracting traditional Chinese medicine. The traditional Chinese medicine pieces need to be decocted for a long time or multiple times. Otherwise, it is very difficult to extract the active ingredients as much as possible. However, with the development of modern decocting technology and the reasons of traditional Chinese medicine materials themselves, the amount of traditional Chinese medicine pieces decocted in a single time of a traditional Chinese medicine prescription is getting larger and larger, and the problem of being difficult to decoct thoroughly is more prominent. As a result, the active ingredients in the medicine remain in the medicine residue pieces and are finally lost, which reduces the efficacy of the traditional Chinese medicine liquid to a certain extent.

[0003] Decocting a large amount of medicine pieces requires a large amount of water, but the amount of added water will cause the final output of the medicine liquid to be much larger than the limit requirement of the dosage. The excess finished medicine liquid will be discarded, and reducing the amount of added water will result in the phenomenon of being difficult to decoct thoroughly or even unable to decoct.

[0004] In addition, the existing decocting machines have the problem of incomplete separation between the medicine liquid and the medicine residue, that is, some highly concentrated medicine liquid will remain in the medicine residue and finally be lost with the medicine residue. Before the next decocting operation, the cleaning is not thorough. Most of them are only washed with water, which can only wash away the surface waste liquid, and the adsorbed medicine stains on the wall and bottom basically still remain inside the machine and are decocted together with the next prescription, causing potential safety and hygiene hazards.

[0005] In view of this, the present invention is specifically proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a control method for a drum-type decocting machine to make the cleaning of the decocting machine cleaner.

[0007] To solve the above technical problem, the basic concept of the technical solution adopted by the present invention is: A control method for a drum-type decocting machine includes Receiving a cleaning program execution instruction; Injecting a first preset amount of clear water into the decocting machine; Controlling the heating device to heat the clear water, and driving the drum of the decocting machine to rotate by a motor.

[0008] Further, the step of controlling the heating device to heat the clear water and driving the drum of the decocting machine to rotate by a motor includes While controlling the heating device to work, controlling the motor to drive the drum to continuously rotate in one direction; Preferably, during the process of controlling the heating device to heat water, after monitoring that the water temperature reaches the first set temperature, the heating device is controlled to work intermittently and / or change the heating power so that the water temperature is within the preset temperature range where the first set temperature is located; Also preferably, after monitoring that the time for the motor to drive the roller to rotate reaches the first set time, if it is determined that the cleaning is completed, the motor is controlled to stop working.

[0009] Furthermore, it further includes a draining step. In response to receiving the instruction that the cleaning is completed, the draining device is controlled to work to drain the cleaning water in the roller.

[0010] Furthermore, the step of controlling the draining device to work includes Monitoring that the working time of the draining device reaches the set draining duration, then it is judged that the draining is completed.

[0011] Furthermore, the decocting machine has a decocting program. In response to the instruction of the decocting program, the heating device is controlled to work according to the obtained set decocting duration and decocting temperature.

[0012] Furthermore, the steps of the decocting process include Monitoring that the decocting working time reaches the second preset duration, then the decocting ends. During the decocting process, the motor drives the roller to rotate forward and backward intermittently, and at the same time the heating device heats.

[0013] Furthermore, the steps of the heating device heating include Controlling the heating device to heat water. After monitoring that the water temperature reaches the second set temperature, start timing, and control the heating device to work intermittently and / or change the heating power so that the water temperature is within the preset temperature range where the second set temperature is located; Monitoring that the working duration of the heating device within the preset temperature range where the second set temperature is located reaches the preset duration of the first heating stage, then control the heating device to perform the decocting of the second heating stage; Monitoring that the water temperature reaches the third set temperature, then re-start timing, and control the heating device to work intermittently and / or change the heating power so that the water temperature is within the preset temperature range where the third set temperature is located; Monitoring that the working duration of the heating device within the preset temperature range where the third set temperature is located reaches the preset duration of the second heating stage, then end the decocting program.

[0014] Furthermore, the decocting machine has a soaking program. Corresponding to the instruction of the soaking program, soaking is carried out according to the obtained set soaking duration. Pour the second preset amount of clear water into the decocting pot, and soak according to the set soaking duration. During the soaking process, the motor intermittently drives the roller to rotate forward and backward.

[0015] Furthermore, the steps of the soaking process are Inject a second preset amount of clear water into the decoction pot. After the water injection is completed, monitor the soaking time. When it reaches the third preset duration, the soaking ends. During the soaking process, the motor drives the roller to rotate intermittently in the forward and reverse directions alternately.

[0016] Furthermore, it also includes a water replenishment step. After receiving the instruction that the soaking is completed, determine whether water replenishment is needed. If so, inject a third preset amount of clear water into the decoction pot. After the injection is completed, start the decocting program; if not, directly start the decocting program.

[0017] After adopting the above technical solutions, the present invention has the following beneficial effects compared with the prior art: 1. In the cleaning program, the heating device is used to heat the cleaning water, and the motor is used to drive the roller to rotate. In the cleaning step, after heating to the set temperature by the heating device, the temperature is maintained within a range, increasing the cleaning cleanliness; 2. In the drainage step, the set drainage duration is used to control the end of drainage, simplifying the drainage monitoring scheme, and at the same time achieving the purpose of complete drainage; 3. Then, in cooperation with the decocting program, according to the set decocting duration and decocting temperature, the heating device is used to control the temperature during the decocting process, reducing manual intervention and enabling more stable temperature control by the heating device; 4. During the heating process, the temperature change is controlled by the duration of different heating stages, reducing manual monitoring, making the decocting process more convenient, and realizing automatic decocting; 5. Then, in cooperation with the soaking program, the motor intermittently drives the roller to rotate forward and backward, making the soaking more sufficient.

[0033] Specifically, a drain outlet is provided at the bottom end of the pot body 29. In one implementation, the drain outlet is connected to a three-way valve, and the three-way valve is respectively connected to a drain pipe and a medicine discharge pipe. The drain pipe and the medicine discharge pipe are respectively communicated to the outside of the box body 1. After the decocting is completed, the three-way valve connects the pot body 29 and the medicine discharge pipe, and the medicinal liquid is discharged through the medicine discharge pipe.

[0034] In a further implementation, a cylinder cover 22 is provided on the cylinder 21. The cylinder 21 has a circumferentially open cylindrical structure, and the cylinder cover 22 is covered at the opening for sealing.

[0035] Specifically, a fixing plate 211 is correspondingly attached to the opening of the cylinder 21. A limiting plate 212 protrudes from the fixing plate 211. A chute is formed by the space between the limiting plate 212 and the fixing plate 211. A part of the cylinder cover 22 is slidably located in the chute for sealing the opening of the cylinder 21. The cylinder cover 22 includes a mounting plate 213, a cover handle 23, a heat insulation plate 231 and a side plate 232. The mounting plate 213 is connected to the heat insulation plate 231. The mounting plate 213 is sized corresponding to the fixing plate 211. The mounting plate 213 is provided with a notch 214. The notch 214 is sized and positioned corresponding to the limiting plate 212, and the mounting plate 213 can pass through the notch and be located in the chute. The heat insulation plate 231 is formed by connecting a plurality of curved surfaces. Side plates 232 are connected to both ends of the curved surface, and a cover handle 23 is connected between the two side plates 232. The cylinder cover 22 places the mounting plate 213 at the bottom of the cylinder cover 22 in the chute corresponding to the notch 214 of the fixing plate 211, and then slides along the axial direction of the cylinder 21 so that the mounting plate 213 is clamped between the fixing plate 211 and the limiting plate 212 to prevent the cylinder cover 22 from falling off during the rotation of the cylinder 21.

[0036] In a further embodiment, as shown in the figure, the drum 21 includes barrel walls 25 on both axial sides. Positioning holes 233 are provided on the barrel walls 25 corresponding to pin holes 27. The barrel cover 21 is installed on the barrel walls 25 through locking pins 24 and cooperates with the fixing plate 211 to prevent the barrel cover 21 from rotating circumferentially.

[0037] In a further embodiment, a shaft hole 234 is provided at the axial position of the barrel wall 25 of the drum 21. A rotating shaft is rotatably installed in the shaft hole 234. The support base 3 is a hollow chamber formed by a bracket. A driving mechanism 7 is provided near one end along the axial direction of the drum 21. The driving mechanism 7 drives the rotating shaft to rotate, and then drives the drum 21 to rotate.

[0038] In a further embodiment, an eccentric wheel locking mechanism 8 is provided at the other end of the drum 21 corresponding to the driving mechanism 7. One end of the eccentric wheel locking mechanism 8 is connected to the other end of the drum 21 through a rotating shaft. The rotating shaft is inserted into the shaft hole 234 through the eccentric locking mechanism 8 and cooperates with the rotating shaft at the other end to rotatably place the drum 21 in the pot body 29.

[0039] Specifically, a flat plate is provided at one end of the pot body 29 corresponding to the driving mechanism 7. The eccentric locking mechanism 8 includes a lock catch 81 and a handle 82. The lock catch 81 is rotatably installed on the flat plate. The handle 82 is rotatably clamped in the lock catch 81. One end of the handle 82 is connected to a connecting rod, and the other end of the connecting rod is connected to an eccentric wheel. A shaft sleeve is provided at the shaft hole of the pot body 29. The rotating shaft is movably arranged in the shaft hole and the shaft sleeve. Two baffles are spaced apart at the end of the rotating shaft away from the drum. The eccentric wheel is located between the baffles. The connecting rod rotates to drive the eccentric wheel to rotate, and the eccentric wheel drives the rotating shaft to move axially to complete the assembly and disassembly of the drum 21. The lock catch 81 is symmetrically arranged on the flat plate along the axis of the connecting rod. The lock catch 81 is controlled to rotate and open, so that the handle 82 can rotate out of the lock catch 81 and rotate to another lock catch 81. The lock catch 81 is in a locked state under normal conditions and rotates and opens in a direction away from the handle 82 to enable the handle to rotate.

[0040] In a further embodiment, a slide rail groove 26 is provided on the barrel wall 25 of the drum 21. One end of the slide rail groove 26 extends to the shaft hole 234, and the other end extends to the outer periphery of the barrel wall 25. The rotating shaft slides in the slide rail groove 26 to complete the assembly and disassembly of the drum 21.

[0041] Specifically, the slide rail groove 26 is used for assembly. The slide rail groove 26 protrudes from the cylinder wall 25 and is arranged on the outside. One end extends to the shaft hole 234, and the other end extends to the outer periphery of the cylinder wall 25. The shaft hole 234 can penetrate the cylinder wall 25 or, relative to the depth of the slide rail groove 26, the depth of the shaft hole 234 is deeper, so that during the rotation of the drum 21, the rotating shaft will not fall off along the slide rail groove 26. During the installation process, the rotating shaft moves along the slide rail groove 26 from the outer periphery to the shaft hole 234, so that the drum 21 can rotate and be located inside the pot body 29.

[0042] In a further embodiment, a protrusion 28 is provided inside the drum 21. The protrusion 28 extends axially and is evenly spaced circumferentially. During the rotation of the protrusion 28, the tablets inside the stirring drum 21 are flipped, and at the same time, the water inside the pot body 29 is stirred to fully blend the liquid medicine. In this way, the problem that using a large amount of water to fully fry the tablets results in the output dose of the medicine being far greater than the limit requirement of the dosage for taking, and the problem that it is difficult to fully fry the tablets when reducing the amount of added water can be solved. Moreover, the provision of the protrusion 28 can also avoid the problem that the tablets cannot be fully immersed in water and cannot be fully decocted. By flipping the medicine with the protrusion 28 and stirring the liquid medicine at the same time, the tablets do not need to be fully immersed in water, nor do they need to add too much water, achieving a relative balance between fully frying the tablets, the amount of added water, and the dosage for taking.

[0043] In a further embodiment, shock-absorbing wheels 10 are provided at the bottom of the support base 3, which facilitates the movement of the decocting machine and at the same time reduces the vibration generated during the operation of the decocting machine.

[0044] Specifically, the shock-absorbing wheel 10 includes a roller and a wheel column. The wheel column is telescopically arranged on one side of the roller. During the movement, the wheel column contracts and the roller contacts the ground. After positioning and during the working process, the wheel column extends and contacts the ground surface. The wheel column has a certain elasticity and is used to reduce the vibration generated by the decocting machine during the working process.

[0045] In a further embodiment, an operation display screen 13 is also provided on the box body 1, which is used to display the working state of the decocting machine, facilitating the operator to observe and operate according to the working state of the decocting machine. An emergency stop switch is provided on one side of the display screen 13. The operator can forcibly stop the work through the emergency stop switch according to the working conditions, improving the safety of the work.

[0046] In the embodiments of the present invention, the box body 1 forms an outer appearance shell and is sleeved on the support base 3. A hollow chamber is formed inside the shell, and the upper side is provided with an opening. The pot body 29 is placed into the box body 1 from the opening. The upper side of the pot body 29 is provided with an opening, and a support plate extending outward in the circumferential direction of the opening is erected at the opening and is supported once by the box body 1. The support base 3 provides secondary support for the decocting pot assembly 2, mainly through the support base 3. A shock-absorbing wheel 6 is installed at the bottom end of the support base 3 to shock-absorb the decocting machine in the working state. The buffer pad 32 on the support base 3 provides secondary shock absorption. The roller 21 is driven to rotate by a driving motor. The roller 21 is provided with an opening, and a cylinder cover 22 is provided at the opening. A number of filter holes are provided on the roller 21. The cylinder cover 22 is provided with a cover handle 23 and an assembly plate 231, and a number of filter holes are also provided on the assembly plate 231. The medicinal liquid is discharged through the filter holes.

[0047] As Figure 8 shown, the present invention also provides a control system for the above-mentioned roller decocting machine, including a soaking control system, a temperature control system, a decocting control system, a time control system, a display control system, and a safety control system. The soaking control module controls the driving mechanism 7 to drive the roller 21 to rotate forward and backward, so that the tablets are fully soaked through. The temperature control module controls the temperature during the decocting process of the medicinal liquid and the water temperature during the cleaning process. The decocting module controls the driving mechanism 7 to drive the roller 21 to rotate forward and backward, so that the tablets are fully decocted. The dehydration module controls the driving mechanism 7 to drive the roller 21 to rotate at a high speed, so as to fully separate the medicinal liquid and the medicinal residues after the decocting is completed, and make the medicinal liquid in the medicinal tablets fully precipitate. The time control module monitors the control of the soaking time, the decocting time, and the cleaning time. The display control module realizes human-machine interaction, displays the high-temperature temperature of the decocting machine and the setting of the time, and at the same time displays various parameters during the decocting process. The safety control module ensures the absolute safety of the decocting machine during the working process, and realizes functions such as detecting whether the roller is fixed and over-temperature alarm.

[0048] Put the traditional Chinese medicine decoction pieces into the drum. On the display control module, set the soaking time, decocting time, and water injection volume of the decoction machine. Open the drum cover 22 and the pot cover 11, put the medicine pieces into the drum 21, open the solenoid valve to inject water into the pot body 29. After the water injection volume reaches the set value, start the soaking mode. The time control system monitors the soaking duration. After a period of time, it transmits a signal to the driving mechanism 7, which drives the drum 21 to turn over. After turning over, continue soaking. After the soaking is completed, the time control system transmits a signal to start decocting, controls the driving mechanism 7 to drive the drum 21 to turn over, and the time control system monitors the decocting time. After the decocting is completed, the decocted liquid is discharged through the drainage device 4. The time control system monitors the discharge time. After reaching the set time, the liquid is discharged. After the discharge, the time control system transmits a signal to the driving mechanism 7 to make the driving mechanism 7 drive the drum 21 to rotate at a high speed, so that the medicine pieces in the drum 21 are separated from the liquid. The time control system monitors the discharge time of the liquid. After the discharge is completed, a signal is transmitted to the cleaning system, and water is injected into the drum through the solenoid valve. The water injection volume is recorded by the flow meter. After the water injection volume reaches the set value, the temperature control system heats the water in the pot body 29 and monitors the temperature in the pot. After reaching the set value, a signal is transmitted to the driving mechanism 7 to drive the drum 21 to rotate for cleaning. After the cleaning is completed, it is discharged through the drainage device 4.

[0049] The present invention also discloses a control method for the above-mentioned drum-type decoction machine, which includes: Receive the cleaning program execution instruction; Inject a first preset amount of clean water into the decoction machine; Control the heating device to heat the clean water, and the motor drives the drum of the decoction machine to rotate.

[0050] Specifically, after receiving the cleaning program execution instruction, inject a first preset amount of clean water into the decoction pot, control the heating device to heat the clean water. While heating, the motor drives the drum of the decoction machine to continuously rotate at a high speed in one direction. During the process of controlling the heating device to heat the water, monitor the water temperature. After reaching the first set temperature, control the heating device to intermittently work and / or change the heating power so that the water temperature is within the preset temperature range where the first set temperature is located. After monitoring that the time for the motor to drive the drum to rotate reaches the first set time, determine that the cleaning is completed, and then control the motor to stop working. The cleaning duration is the same as the duration of the drum rotation.

[0051] In a further implementation, the decoction machine also has a decocting program. In response to the instruction of the decocting program, control the heating device to work according to the obtained set decocting duration and decocting temperature.

[0052] Specifically, set the decocting working duration to the second preset duration. When it is monitored that the decocting working duration reaches the second preset duration, the decocting ends. During the decocting process, the motor drives the drum to rotate forward and backward intermittently, and at the same time, heating is carried out through the heating device. Since the decocting does not end at the same temperature during the decocting process, there are multiple heating stages for the heating device. Here, taking two heating stages as an example, during the process of controlling the heating device to heat water, after monitoring that the water temperature reaches the second set temperature, start timing, and control the heating device to make the water temperature within the preset temperature range where the second set temperature is located by means of intermittent operation and / or changing the heating power. At the same time, monitor that the working duration of the heating device within the preset temperature range where the second set temperature is located reaches the preset duration of the first heating stage, then control the heating device to perform the decocting of the second heating stage, and control the heating device to make the water temperature within the preset temperature range where the third set temperature is located by means of intermittent operation and / or changing the heating power. After monitoring that the water temperature reaches the third set temperature, start timing again, and monitor that the working duration of the heating device within the preset temperature range where the third set temperature is located reaches the preset duration of the second heating stage, then end the decocting program. The preset duration of the second heating stage is the same as the remaining decocting duration. This embodiment is not the only decocting method. If more heating stages are required, repeat the above method.

[0053] In a further embodiment, the decocting machine has a soaking medicine program. In response to the instruction of the soaking medicine program, soak the medicine according to the obtained set soaking medicine duration, inject a second preset amount of clear water into the decocting pot, and soak the medicine according to the set soaking medicine duration. During the soaking process, the motor intermittently drives the drum to rotate forward and backward.

[0054] Specifically, the steps of the soaking process of the decocting machine are as follows: inject a second preset amount of clear water into the decocting pot. After the water injection is completed, monitor that the soaking medicine work reaches the third preset duration, then the soaking ends. During the soaking process, the motor drives the drum to rotate forward and backward alternately intermittently. Start timing from the end of the water injection, judge whether the time reaches the preset time. After reaching, control the motor to drive the drum to rotate once, and start timing again. After reaching the preset time here, control the motor to drive the drum to rotate once again until the soaking ends.

[0055] In a further embodiment, it further includes a water replenishing step. After receiving the instruction that the soaking medicine is completed, judge whether water replenishment is required. If so, inject a third preset amount of clear water into the decocting pot. After the injection is completed, start the decocting program; if not, directly start the decocting program.

[0056] Specifically, it can be judged whether water replenishment is required manually, and the water replenishment is controlled manually. It can also set the water replenishment amount, judge the required water replenishment amount through the flow meter, and automatically replenish the water. Or the decocting machine detects and judges whether water replenishment is required through the sensor.

[0057] The control method of the present invention is as follows: First, put the tablets or medicine bags to be decocted into the decocting machine, set the parameters of the soaking program, decocting program, and cleaning program on the display screen 13, then click start, and execute according to the above-mentioned soaking program. After the soaking is completed, the decocting program will be automatically executed. After the decocting program is completed, it also includes the step of discharging the medicinal liquid. Determine whether the medicinal liquid is discharged by the discharging duration. After the medicinal liquid is discharged, take out the tablets and the medicinal liquid, and then select to execute the cleaning program again, and execute the cleaning according to the above-mentioned cleaning program steps.

[0058] The tablets can be put in and taken out manually or by a robot. The robot opens the decocting machine according to the set program, puts in or takes out the medicine bag, and then operates to select the decocting or cleaning program.
