For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0095] As shown in Figures 1 to 22 The present application discloses a kind of micro-pressure circulation decocting traditional Chinese medicine automation production line.

[0096] Micro-pressure circulation decocting traditional Chinese medicine automation production line includes decocting pot 1, decocting and filling unit 2, cleaning unit 3 and flow transfer conveying line 4. Decocting and filling unit 2 and cleaning unit 3 are arranged along the conveying direction of flow transfer conveying line 4, and cleaning unit 3 is located downstream of decocting and filling unit 2. Flow transfer conveying line 4 is used to drive decocting pot 1 to flow between each process unit.

[0097] The micro-pressure circulation decocting traditional Chinese medicine automatic production line is also matched with a control system, the control system is connected with signals of all devices in the micro-pressure circulation decocting traditional Chinese medicine automatic production line. The control system can send control instructions to all devices in the micro-pressure circulation decocting traditional Chinese medicine automatic production line, and all devices in the micro-pressure circulation decocting traditional Chinese medicine automatic production line can obtain the control instructions sent by the control system and execute corresponding actions according to the obtained control instructions.

[0098] The decocting pot 1 comprises an outer barrel 11 with a hollow top opening, an inner barrel 12 with a hollow top opening, and a barrel cover 13 capable of closing the top barrel opening of the inner barrel 12. The outer barrel 11 is in the shape of a cylinder. The outer barrel 12 is also in the shape of a cylinder. The outer barrel diameter of the inner barrel 12 is smaller than the barrel opening diameter of the outer barrel 11. Because the outer barrel diameter of the inner barrel 12 is smaller than the barrel opening diameter of the outer barrel 11, the inner barrel 12 can be loaded into the inside of the outer barrel 11 from the barrel opening of the outer barrel 11. The barrel cover 13 covers the barrel opening of the inner barrel 12 to close the barrel opening of the inner barrel 12.

[0099] In this embodiment, the outer barrel flange 111 of the outer barrel 11 is in the form of a circular ring structure extending outward horizontally. The inner barrel flange 121 of the inner barrel 12 is also in the form of a circular ring structure extending outward horizontally. The outer diameter of the inner barrel flange 121 is greater than the barrel opening diameter of the outer barrel 11. The barrel height of the inner barrel 12 is smaller than the barrel height of the outer barrel 11. When the inner barrel 12 is loaded into the inside of the outer barrel 11 from the top barrel opening of the outer barrel 11, the inner barrel flange 121 on the inner barrel 12 is pressed on the outer barrel flange 111 of the outer barrel 11.

[0100] When the inner barrel 12 is loaded into the inside of the outer barrel 11, the inner barrel flange 121 of the inner barrel 12 is pressed on the outer barrel flange 111 of the outer barrel 11, and a distance is left between the outer surface of the barrel bottom of the inner barrel 12 and the inner surface of the barrel bottom of the outer barrel 11.

[0101] Preferably, the outer edge of the inner barrel flange 121 is provided with two extension parts 1211 extending outward horizontally, and the extension parts 1211 are integrally formed with the inner barrel flange 121. The two extension parts 1211 are centrally symmetrically arranged with respect to the central axis of the inner barrel 12. The extension parts 1211 extend to the outside of the outer edge of the outer barrel flange 111. By arranging the extension parts 1211 and extending the extension parts 1211 to the outside of the outer edge of the outer barrel flange 111, when the inner barrel 12 is taken out of the inside of the outer barrel 11, the inner barrel flange 121 can be lifted from below the extension parts 1211, thereby facilitating the lifting of the inner barrel 12 out of the inside of the outer barrel 11.

[0102] In the present embodiment, when the inner barrel 12 is placed inside the outer barrel 11, the bottom end surface of the inner barrel flange 121 is fitted with the top end surface of the outer barrel flange 111, and the outer diameter of the inner barrel 12 is smaller than the inner diameter of the outer barrel 11, so that a closed sealed cavity 14 is formed between the outer wall of the inner barrel 12 and the inner wall of the outer barrel 11. A pressure relief member 15 is installed on the inner barrel flange 121, and the pressure relief member 15 is in communication with the inside of the sealed cavity 14. When the gravity valve cap of the pressure relief member 15 is opened, the pressure relief member 15 communicates the inside of the sealed cavity 14 with the outside space of the outer barrel 11.

[0103] Specifically, the pressure relief member 15 adopts a gravity pressure limiting valve. The pressure relief member 15 includes a valve body 151 fixed on the inner barrel flange 121, and a gas passage 152 is arranged in the valve body 151. One end of the gas passage 152 is in communication with the sealed cavity 14, and the other end of the gas passage 152 is in communication with the top end surface of the valve body 151. A gravity valve cap 153 is arranged on the top of the valve body 151, and the gravity valve cap 153 covers the top of the valve body 151. The bottom of the gravity valve cap 153 is provided with a valve rod 1531 extending into the gas passage 152 to close the gas passage 152, and the valve rod 1531 is integrally formed with the gravity valve cap 153. When the gravity valve cap 153 covers the valve body 151, the valve rod 1531 closes the gas passage 152, and when the gravity valve cap 153 is removed from the valve body 151, the gas passage 152 communicates the sealed cavity 14 with the outside air, so that the air in the sealed cavity 14 can be discharged to the outside air.

[0104] A plurality of communication holes 122 are densely arranged on the bottom of the lateral barrel wall of the inner barrel 12, and the communication holes 122 penetrate the lateral barrel wall of the inner barrel 12. When the inner barrel 12 is located inside the outer barrel 11, the communication holes 122 communicate the internal space of the inner barrel 12 with the internal space of the outer barrel 11. When the inner barrel 12 is placed inside the outer barrel 11, the communication holes 122 communicate the internal space of the inner barrel 12 with the sealed cavity 14 formed between the inner barrel 12 and the outer barrel 11.

[0105] When the medicinal materials are decocted, first, the inner barrel 12 is placed inside the outer barrel 11, then the medicine bag filled with medicinal materials is put into the internal space of the inner barrel 12, and then water with a volume required for decocting the medicinal materials is added into the inner barrel 12. The water poured into the inner barrel 12 needs to ensure that the water level is above all the communication holes 122. The barrel opening of the inner barrel 12 is closed by the barrel cover 13, and finally the outer barrel 11 is heated by the electromagnetic oven.

[0106] When the existing electromagnetic stove is used to heat the decocting pot 1, the decocting pot 1 is placed on the cooking surface of the electromagnetic stove. When the electromagnetic stove is used to simmer the decocting pot 1, the outer ring of the electromagnetic stove heats the decocting pot at this time. The water in the decocting pot is heated to a higher temperature, and the water vapor generated by the heating of the water enters the inside of the sealed cavity 14. As the water vapor increases, the pressure in the sealed cavity 14 also gradually increases. When the pressure in the sealed cavity 14 is greater than the pressure in the space inside the inner barrel 12, the pressure in the sealed cavity 14 pushes the medicinal liquid through the communication hole 122 and into the inside of the inner barrel 12. The medicinal liquid that is pressed into the inside of the inner barrel 12 flushes the medicinal bag placed in the inner barrel 12.

[0107] After the medicinal liquid is pressed into the inside of the inner barrel 12, the pressure relief member 15 is opened. When the pressure relief member 15 is opened, the steam in the sealed cavity 14 is discharged through the pressure relief member 15. When the steam is gradually discharged by the pressure relief member 15, the air pressure in the sealed cavity 14 gradually decreases. When the pressure in the sealed cavity 14 is less than the pressure in the space inside the inner barrel 12, the medicinal liquid in the inner barrel 12 is pressed into the sealed cavity 14 through the communication hole 122.

[0108] By repeatedly controlling the pressure in the sealed cavity 14 and the space inside the inner barrel 12, the medicinal liquid can continuously flush the medicinal bag, and the medicinal liquid and the medicinal bag can be fully combined to ensure that the decocted medicinal soup has a greater concentration.

[0109] In this embodiment, the bottom of the outer barrel 11 is provided with a horizontally arranged rectangular bottom tray 16, and the bottom end surface of the bottom tray 16 is provided with a containing cavity 161. The barrel bottom of the outer barrel 11 vertically penetrates the bottom tray 16 from the top end of the bottom tray 16, and the barrel bottom of the outer barrel 11 extends into the inside of the containing cavity 161. The bottom tray 16 is fixedly connected with the outer barrel 11. The lateral cavity wall of the containing cavity 161 is spaced apart from the barrel bottom of the outer barrel 11. The height of the outer surface of the barrel bottom of the outer barrel 11 is higher than the bottom end surface of the bottom tray 16. When the decocting pot is placed on the shelf or the ground, the barrel bottom of the outer barrel 11 is spaced apart from the shelf or the ground, thereby protecting the outer surface of the barrel bottom of the outer barrel 11, so that the outer surface of the barrel bottom of the outer barrel 11 is not easily scratched when the outer barrel 11 is stored and taken.

[0110] In this embodiment, the decocting and filling unit 2 comprises a linearly extending track group 21, and a double-column stacker crane 22 is arranged on the track group 21. The double-column stacker crane 22 can move on the track group 21 along the extension direction of the track group 21.

[0111] Specifically, the track group 21 includes two parallel straight rails 211. The double-column stacker 22 is located on the two parallel straight rails 211 and can move along the extension direction of the straight rails 211.

[0112] A plurality of decoction mechanisms 23 are arranged on both sides of the track group 21, and the decoction mechanisms 23 on the same side of the track group 21 are arranged along the extension direction of the track group 21. The decoction mechanism 23 is used for heating the decoction pot 1 to decoct the medicinal materials and water in the decoction pot into a traditional Chinese medicine decoction.

[0113] On one side of the track group 21, a plurality of medicinal liquid filling mechanisms 24 are arranged along the extension direction of the track group 21. The medicinal liquid filling mechanism 24 adopts a medicinal liquid overturning packaging machine. After the decocted medicinal liquid is poured into the medicinal liquid overturning packaging machine, the medicinal liquid overturning packaging machine performs packaging.

[0114] On the other side of the track group 21, a plurality of static filtration mechanisms 25 are arranged along the extension direction of the track group 21. The number of the medicinal liquid filling mechanisms 24 is the same as that of the static filtration mechanisms 25. One medicinal liquid filling mechanism 24 and one static filtration mechanism 25 form a group, and the medicinal liquid filtered by the static filtration mechanism 25 is poured into the medicinal liquid filling mechanism 24 in the same group.

[0115] When the double-column stacker 22 moves along the extension direction of the track group 21, the double-column stacker 22 walks between the decoction mechanism 23, the medicinal liquid filling mechanism 24, and the static filtration mechanism 25. The double-column stacker 22 is used for grabbing and transporting the decoction pot 1, sending the decoction pot into the decoction mechanism 23, the medicinal liquid filling mechanism 24, or the static filtration mechanism 25, or taking the decoction pot 1 out of the decoction mechanism 23, the medicinal liquid filling mechanism 24, or the static filtration mechanism 25.

[0116] Specifically, the decoction mechanism 23 includes a rack 231. The rack 231 includes an upper truss 2311 and a lower truss 2312 arranged opposite to each other. The upper truss 2311 and the lower truss 2312 are parallel to each other. Both the upper truss 2311 and the lower truss 2312 are rectangular frame structures in this embodiment. The four corners of the upper truss 2311 and the four corners of the lower truss 2312 are arranged opposite to each other. A column 2313 is arranged at each corner of the upper truss 2311. The column 2313 is vertically arranged. The top of the column 2313 is fixedly connected with the upper truss 2311, and the bottom of the column 2313 is fixedly connected with the lower truss 2312. A foot 2314 is installed at the bottom end of the column 2313.

[0117] Two heating modules 232 are installed on the upper surface of the lower truss 2312 along the length direction of the lower truss 2312, and are used for heating the decoction pot. Two gland pressure regulating devices 233 are arranged along the length direction of the upper truss 2311, and correspond to the heating modules 232 one by one. The gland pressure regulating device 233 is located directly above the corresponding heating module 232. The gland pressure regulating device 233 is connected to the upper truss 2311 through a lifting control device 234, and the lifting control device 234 is vertically arranged. One end of the lifting control device 234 is fixed to the upper truss 2311, and the other end of the lifting control device 234 is connected to the gland pressure regulating device 233. The lifting control device 234 drives the gland pressure regulating device 233 to rise and fall in the vertical direction.

[0118] In the embodiment, the number of heating modules 232 and gland pressure regulating devices 233 is two, and in actual production, the number of heating modules 232 and gland pressure regulating devices 233 can be set according to the actual production output, which can be one, three or more. The number of heating modules 232 and gland pressure regulating devices 233 is the same, and one heating module 232 and one gland pressure regulating device 233 are set as a group.

[0119] When decocting medicinal materials, place the decoction pot containing medicinal materials and water above the heating module 232, and drive the lifting control device 234 to move the gland pressure regulating device 233 downward until the gland pressure regulating device 233 presses the inner barrel flange 121 of the decoction pot. After the gland pressure regulating device 233 presses the inner barrel flange 121, it applies pressure to the inner barrel flange 121, so that the inner barrel flange 121 and the outer barrel flange 111 can be tightly attached. At the same time, the gland pressure regulating device 233 can control the opening and closing of the pressure relief piece 15, so as to adjust the size of the internal pressure of the sealed cavity in the decoction pot.

[0120] In the embodiment, the heating module 232 includes a rectangular mounting bracket 2321 fixed to the lower truss 2312. The mounting bracket 2321 is internally provided with a mounting cavity 23211. The top end surface of the mounting bracket 2321 is provided with a mounting port 23212 connected to the inside of the mounting cavity 23211. An electromagnetic oven 2322 for heating the decoction pot is movably connected in the mounting cavity 23211. The electromagnetic oven 2322 is horizontally placed, and the cooktop of the electromagnetic oven 2322 faces upward. The electromagnetic oven 2322 can move vertically in the mounting cavity 23211. When the decoction pot needs to be heated, place the decoction pot on the cooktop of the electromagnetic oven 2322, and turn on the electromagnetic oven 2322 to heat the decoction pot.

[0121] The bottom end of the electromagnetic oven 2322 is provided with four vertically arranged elastic floating supports 2323, the top end of the elastic floating support 2323 is fixedly connected with the electromagnetic oven 2322. The bottom end of the elastic floating support 2323 is fixedly connected with the bottom surface of the installation cavity 23211. The elastic floating support 2323 supports the electromagnetic oven 2322. When the cooking pot is not placed on the electromagnetic oven 2322, the elastic floating support 2323 supports the electromagnetic oven 2322, and the cooking surface of the electromagnetic oven 2322 is higher than the top end surface of the installation support 2321. When the cooking pot is placed on the cooking surface of the electromagnetic oven 2322, the electromagnetic oven 2322 is gradually moved downward due to the gravity of the cooking pot 1, and the elastic floating support 2323 is compressed at this time.

[0122] Preferably, a vertical guide sleeve 23213 is fixedly arranged in the installation cavity 23211, the electromagnetic oven 2322 passes through the inner hole of the guide sleeve 23213, and the outer side wall surface of the electromagnetic oven 2322 abuts against the hole wall of the inner hole of the guide sleeve 23213. The guide sleeve 23213 provides guidance for the movement of the electromagnetic oven 2322, so that the movement of the electromagnetic oven 2322 is along the vertical direction of the guide sleeve 23213, preventing the electromagnetic oven 2322 from being skewed during movement.

[0123] In this embodiment, the installation support 2321 is fixedly provided with a baffle 2324 at the top middle position of the outer side surface of each side wall, the top end of the baffle 2324 is higher than the top end surface of the installation support 2321 and the top end surface of the electromagnetic oven 2322 when the electromagnetic oven 2322 is at the highest position. Three baffles 2324 are provided with chamfers 23241 at the top side of the side facing the electromagnetic oven 2322. When the cooking pot is placed on the electromagnetic oven 2322, the bottom plate tray 16 of the cooking pot is first clamped into the space surrounded by the four baffles 2324. The outer side surface of the four side walls of the bottom plate tray 16 abuts against the side surface of the four baffles 2324 facing the electromagnetic oven 2322 one by one. When the bottom plate tray 16 enters the space surrounded by the four baffles 2324, the cooking pot 1 is in a vertical state as a whole.

[0124] When the cooking pot 1 is lowered and placed on the cooking surface of the electromagnetic oven 2322, the bottom of the outer barrel 11 is located on the cooking surface of the electromagnetic oven 2322. The weight of the cooking pot 1 and the weight of the medicinal materials and water in the cooking pot 1 are all applied to the electromagnetic oven 2322, which is pressed to move downward, and at this time the elastic floating support 2323 is compressed to store energy until the bottom end surface of the bottom plate tray 16 abuts against the top end surface of the installation support 2321.

[0125] In the embodiment, the heating module 232 further comprises a proximity photoelectric assembly 2325 and a processor which are installed on the mounting bracket 2321. The proximity photoelectric assembly 2325 comprises a frame body 23251 which is fixed on the mounting bracket 2321, and a proximity switch 23252 which is installed on the frame body 23251 and has a detection end facing the induction cooker 2322. The proximity switch 23252 and the induction cooker 2322 are both in signal connection with the processor, and the proximity switch 23252 sends a detection signal to the processor, and the processor sends a control instruction to the induction cooker 2322 according to the detection signal of the proximity switch 23252 to control the opening and closing of the induction cooker 2322.

[0126] When the elastic floating bracket 2323 is not stressed and compressed, the induction cooker 2322 is in the highest position, and the proximity switch 23252 is below the induction cooker 2322. When the cooking pot is placed on the induction cooker 2322 to compress the elastic floating bracket 2323, the induction cooker 2322 is horizontally opposite to the proximity switch 23252. When the induction cooker 2322 is horizontally opposite to the proximity switch 23252, the proximity switch 23252 detects the induction cooker 2322, and the proximity switch 23252 sends a detection signal to the processor, and the processor sends an opening instruction to the induction cooker 2322, and the induction cooker 2322 is opened to heat the cooking pot. When the induction cooker 2322 is in the up-down misalignment state with the proximity switch 23252, the induction cooker 2322 remains in the closed state.

[0127] Preferably, an adjusting groove 232511 is formed in the frame body 23251, and the length of the adjusting groove 232511 is vertically arranged. The proximity switch 23252 is slidingly connected in the adjusting groove 232511. A fixed plate 23253 is fixed on the top of the frame body 23251, and a through hole vertically penetrating the fixed plate 23253 is formed in the fixed plate 23253. An adjusting screw 23254 vertically penetrating the through hole is slidingly connected in the through hole, and a first nut 23255 and a second nut 23256 are threadedly connected on the adjusting screw 23254, the first nut 23255 is above the fixed plate 23253 and is attached to the upper surface of the fixed plate 23253, and the second nut 23256 is below the fixed plate 23253 and is attached to the lower surface of the fixed plate 23253.

[0128] The maximum width of the first nut 23255 and the second nut 23256 is greater than the hole diameter of the through hole. When it is necessary to adjust the position of the proximity switch 23252, the first nut 23255 and the second nut 23256 are rotated to move the first nut 23255 and the second nut 23256 to the top end or the bottom end of the adjusting screw 23254, so as to drive the proximity switch 23252 to move in the vertical direction in the adjusting groove 232511 and adjust the height position of the proximity switch 23252.

[0129] In the embodiment, the gland pressure regulating device 233 comprises a horizontally arranged gland 2331, and the bottom end surface of the gland 2331 is provided with a recessed cavity 23311. When the gland 2331 abuts against the upper surface of the inner drum flange 121, the pressure relief member 15 is located inside the recessed cavity 23311. Inside the recessed cavity 23311 is arranged a mechanical mechanism 2332 for controlling the opening and closing of the pressure relief member 15, and the mechanical mechanism 2332 is fixed on the gland 2331.

[0130] Specifically, the mechanical mechanism 2332 comprises a valve body air release claw 23321 movably arranged inside the recessed cavity 23311, and a control assembly 23322 for driving the valve body air release claw 23321 to move in the horizontal direction and the vertical direction, and the control assembly 23322 is located between the gland 2331 and the valve body air release claw 23321 and is fixedly connected with the gland 2331.

[0131] Specifically, the control assembly 23322 comprises a vertically arranged vertical movement air cylinder 233221 fixed on the top end outer surface of the gland 2331. The piston rod of the vertical movement air cylinder 233221 faces downward of the gland 2331. The piston rod of the vertical movement air cylinder 233221 vertically penetrates the gland 2331 so as to extend into the recessed cavity 23311, and an opening is arranged on the top end surface of the gland 2331 for the piston rod of the vertical movement air cylinder 233221 to penetrate. A horizontally arranged horizontal movement air cylinder 233222 is fixed on the end head of the piston rod of the vertical movement air cylinder 233221, and the piston rod of the horizontal movement air cylinder 233222 faces the lateral cavity wall of the recessed cavity 23311. The valve body air release claw 23321 is fixed on the end head of the piston rod of the horizontal movement air cylinder 233222.

[0132] When the piston rod of the vertical movement air cylinder 233221 moves, the piston rod of the vertical movement air cylinder 233221 drives the horizontal movement air cylinder 233222 to lift or lower, and when the horizontal movement air cylinder 233222 lifts or lowers, the valve body air release claw 23321 lifts or lowers synchronously with the horizontal movement air cylinder 233222. When the piston rod of the horizontal movement air cylinder 233222 moves, the piston rod of the horizontal movement air cylinder 233222 drives the valve body air release claw 23321 to move in the horizontal direction.

[0133] In the present embodiment, the valve body air release claw 23321 comprises a horizontal portion 233211 in horizontal shape and a vertical portion 233212 in vertical arrangement. The vertical portion of the valve body air release claw 23321 is fixed with the piston rod of the horizontal moving cylinder 233222. A plurality of notches 233213 are arranged along the edge of the horizontal portion 233211 on the side of the horizontal portion 233211 away from the vertical portion 233212. The number of the notches 233213 is the same as the number of the pressure relief members 15. The spacing between the notches 233213 is the same as the spacing between the pressure relief members 15.

[0134] When the pressure cover 2331 is pressed on the boiling pot, the valve body air release claw 23321 is horizontally opposite to the pressure relief members 15, at this time, the horizontal portion 233211 is below the gravity valve cap 153 of the pressure relief members 15, and the notches 233213 on the horizontal portion 233211 are opposite to the pressure relief members 15 one by one. When the horizontal moving cylinder 233222 drives the valve body air release claw 23321 to approach the pressure relief members 15, the horizontal portion 233211 extends below the gravity valve cap 153. When the horizontal portion 233211 extends below the gravity valve cap 153, the vertical moving cylinder 233221 drives the horizontal moving cylinder 233222 and the valve body air release claw 23321 to rise at the same time, the horizontal portion 233211 lifts the gravity valve cap 153, thereby opening the pressure relief members 15. When it is needed to close the pressure relief members 15, the vertical moving cylinder 233221 drives the horizontal moving cylinder 233222 and the valve body air release claw 23321 to descend at the same time, the horizontal portion 233211 drops the gravity valve cap 153, thereby closing the pressure relief members 15, the horizontal moving cylinder 233222 drives the valve body air release claw 23321 to horizontally move away from the gravity valve cap 153, so that the horizontal portion 233211 is separated from the gravity valve cap 153.

[0135] Preferably, the horizontal portion 233211 and the vertical portion 233212 of the valve body air release claw 23321 are integrally formed, and the valve body air release claw 23321 is formed by bending a plate material by 90°.

[0136] In the present embodiment, the lifting control device 234 adopts a cylinder. Two lifting control devices 234 are arranged between each pressure cover 2331 and the upper truss 2311. The two lifting control devices 234 are located on the opposite sides of the pressure cover 2331. By locating the two lifting control devices 234 on the opposite sides of the pressure cover 2331, the lifting control device 234 can make the force borne by the pressure cover 2331 more uniform when driving the pressure cover 2331 to lift, and make the pressure cover 2331 more stable during lifting.

[0137] In the embodiment, a plurality of vertically arranged guide shaft assemblies 235 are arranged between the cover 2331 and the upper truss 2311, and the length of the guide shaft assemblies 235 is telescopic. The guide shaft assemblies 235 are arranged in a plurality of numbers and are arranged in a spaced manner along the circumferential direction of the cover 2331. The top end of the guide shaft assemblies 235 is fixed to the upper truss 2311, and the bottom end of the guide shaft assemblies 235 is fixed to the cover 2331. When the cover 2331 is lifted or lowered, the length of the guide shaft assemblies 235 changes with the movement of the cover 2331. By arranging a plurality of guide shaft assemblies 235 between the cover 2331 and the upper truss 2311, the guide shaft assemblies 235 can guide the movement of the cover 2331, so that the moving direction of the cover 2331 always remains vertical, avoiding the inclination of the cover 2331 during movement.

[0138] Specifically, the guide shaft assembly 235 comprises a fixed sleeve 2351 and a movable rod 2352 arranged coaxially. One end of the movable rod 2352 extends into the inner hole of the fixed sleeve 2351, and the movable rod 2352 can move in the axial direction of the fixed sleeve 2351 in the inner hole of the fixed sleeve 2351. The fixed sleeve 2351 is fixedly connected to the upper truss 2311. The end of the movable rod 2352 outside the fixed sleeve 2351 is fixed to the cover 2331.

[0139] When the cover 2331 moves in the vertical direction, the movable rod 2352 moves synchronously with the cover 2331, and the end of the movable rod 2352 extending into the inner hole of the fixed sleeve 2351 moves in the axial direction of the fixed sleeve 2351. Through the cooperation between the movable rod 2352 and the fixed sleeve 2351, the movement of the cover 2331 is guided, so that the cover 2331 is not easy to shake during vertical movement, thereby improving the stability of the vertical movement of the cover 2331.

[0140] In the embodiment, the static filter mechanism 25 comprises a main frame 251, a first conveyor 252 and a second conveyor 253. The first conveyor 252 is located outside the main frame 251. The second conveyor 253 transversely passes through the bottom of the main frame 251. The first conveyor 252 and the second conveyor 253 are arranged side by side and parallel to each other.

[0141] Both the first conveyor 252 and the second conveyor 253 are double synchronous belt conveyors, and both the first conveyor 252 and the second conveyor 253 comprise two parallel and spaced conveying belts. When the cooking pot is conveyed, the bottom of the cooking pot is pressed on the two parallel conveying belts, and the two conveying belts move synchronously to drive the cooking pot to move, so as to send the cooking pot from the upstream end of the conveying belt to the downstream end of the conveying belt.

[0142] The first lifting transfer machine 2521 is installed on the first conveyor 252 and is located between the two conveying belts of the first conveyor 252. The second lifting transfer machine 2531 is installed on the second conveyor 253 and is located between the two conveying belts of the second conveyor 253. The first lifting transfer machine 2521 and the second lifting transfer machine 2531 are horizontally opposite to each other.

[0143] When the boiling pot 1 is transferred between the first conveyor 252 and the second conveyor 253, when the boiling pot moves to the top of the first lifting transfer machine 2521, the first lifting transfer machine 2521 lifts the boiling pot from the conveying belt and moves the boiling pot to the direction of the second conveyor 253. When the first lifting transfer machine 2521 lifts the boiling pot, the second lifting transfer machine 2531 is synchronously lifted, and the upper surface of the second lifting transfer machine 2531 is flush with the upper surface of the first lifting transfer machine 2521. When the first lifting transfer machine 2521 moves the boiling pot to the direction of the second conveyor 253, the boiling pot moves to the second lifting transfer machine 2531. When the boiling pot completely moves to the second lifting transfer machine 2531, the second lifting transfer machine 2531 is lowered, and the boiling pot falls on the conveying belt of the second conveyor 253. The conveying belt of the second conveyor 253 operates to send the boiling pot to the next process.

[0144] The barrel position correcting device 254 is installed between the two conveying belts of the first conveyor 252 and is located upstream of the first lifting transfer machine 2521. The barrel position correcting device 254 is opposite to the main frame 251.

[0145] Specifically, in the present embodiment, the barrel position correcting device 254 includes a base 2541 fixed between the two conveying belts of the first conveyor 252, and the base 2541 is horizontally arranged. The base 2541 is fixed with the frame of the two conveying belts. A lifting platform 2542 parallel to the base 2541 is arranged above the base 2541, and a vertical movement driving cylinder 2543 is arranged between the lifting platform 2542 and the base 2541, and the vertical movement driving cylinder 2543 is vertically arranged. The piston rod of the vertical movement driving cylinder 2543 faces upward. The cylinder body of the vertical movement driving cylinder 2543 is fixed on the base 2541, and the piston rod of the vertical movement driving cylinder 2543 is fixedly connected with the lifting platform 2542.

[0146] When the piston rod of the vertical movement driving cylinder 2543 moves in the cylinder body, the piston rod of the vertical movement driving cylinder 2543 drives the lifting platform 2542 to move vertically to adjust the height of the lifting platform 2542.

[0147] In the embodiment, the lifting platform 2542 is provided with vertical downward extending guide columns 25421 fixedly connected with the lifting platform 2542 at the four corners of the bottom end of the lifting platform 2542. Vertical guide sleeves 25411 are fixed at the four corners of the base 2541 respectively. The four guide columns 25421 correspond to the four guide sleeves 25411 one by one, and the guide columns 25421 and the corresponding guide sleeves 25411 are coaxially opposite. The guide columns 25421 are inserted into the inner holes of the guide sleeves 25411 and can move along the axial direction of the guide sleeves 25411 in the inner holes of the guide sleeves 25411. When the guide columns 25421 are inserted into the inner holes of the guide sleeves 25411, the outer side wall surfaces of the guide columns 25421 are in close contact with the hole wall surfaces of the inner holes of the guide sleeves 25411. When the lifting platform 2542 moves up and down, the guide columns 25421 move in the inner holes of the guide sleeves 25411, which guides the lifting of the lifting platform 2542 and makes the lifting platform 2542 more stable during lifting.

[0148] In the embodiment, the upper surface of the lifting platform 2542 is slidingly connected with a translation seat 2544, and the upper surface of the translation seat 2544 is a horizontal surface. The upper surface of the translation seat 2544 is used to carry a decoction pot. A transverse movement driving cylinder 2545 is fixed on the lifting platform 2542, and the transverse movement driving cylinder 2545 is transversely arranged. The cylinder body of the transverse movement driving cylinder 2545 is fixed on the lifting platform 2542, and the piston rod of the transverse movement driving cylinder 2545 is fixedly connected with the translation seat 2544. The main body frame 251 is located in the movement direction of the translation seat 2544, and when the translation seat 2544 is moved by the transverse movement driving cylinder 2545, the translation seat 2544 can gradually approach or move away from the main body frame 251.

[0149] Specifically, the upper surface of the lifting platform 2542 is fixed with two guide rails 2546 parallel to each other. The movement direction of the piston rod of the transverse movement driving cylinder 2545 is arranged along the length direction of the two guide rails 2546. The length direction of the two guide rails 2546 is arranged along the arrangement direction of the two conveying belts of the first conveyor 252. The lower surface of the translation seat 2544 is fixed with sliding seats 2547 opposite to the two guide rails 2546. The sliding seats 2547 are clamped on the opposite guide rails 2546 and can move along the length direction of the guide rails 2546 on the connected guide rails 2546. The sliding seats 2547 are fixedly connected with the translation seat 2544.

[0150] When the driving cylinder 2545 drives the horizontal movement of the translation seat 2544, the sliding seat 2547 moves along the guide rail 2546. Through the cooperation between the sliding seat 2547 and the guide rail 2546, the stability of the translation seat 2544 during movement is improved, so that the translation seat 2544 moves more stably and the shaking of the translation seat 2544 during movement is reduced.

[0151] Specifically, the translation seat 2544 includes a first moving part 25441 and a second moving part 25442 which are parallel to each other. The first moving part 25441 and the second moving part 25442 are connected through a connecting arm 25443. One end of the connecting arm 25443 is fixed to the first moving part 25441 by a bolt, and the other end of the connecting arm 25443 is fixed to the second moving part 25442 by a bolt. The upper surface of the first moving part 25441 and the upper surface of the second moving part 25442 are located on the same horizontal plane.

[0152] In this embodiment, the translation seat 2544 of the barrel position correcting device 254 can pass between the two conveying belts of the first conveyor 252. When the lifting platform 2542 is lifted to the highest position, the upper surface of the translation seat 2544 is located at a height higher than the conveying surface of the conveying belts of the first conveyor 252. When the lifting platform 2542 is lowered to the lowest position, the upper surface of the translation seat 2544 is located at a height lower than the conveying surface of the conveying belts of the first conveyor 252.

[0153] In this embodiment, the first conveyor 252 is fixed with a positioning piece 255, which is located on the side of the barrel position correcting device 254 facing the main body frame 251. The positioning piece 255 is also located in the moving direction of the translation seat 2544. When the cooking pot is placed on the translation seat 2544, the translation seat 2544 drives the cooking pot to move in the direction of the main body frame 251, and the cooking pot can be moved to the state of abutting against the positioning piece 255. When the cooking pot abuts against the positioning piece 255, it means that the cooking pot has moved to the specified position.

[0154] In this embodiment, the side of the main body frame 251 facing the barrel position correcting device 254 is provided with a grabbing mechanism 256 which is slidingly connected to the main body frame 251. The moving direction of the grabbing mechanism 256 is vertically arranged. A vertically arranged pushing cylinder 257 is arranged above the grabbing mechanism 256, and the piston rod of the pushing cylinder 257 faces the grabbing mechanism 256. The cylinder body of the pushing cylinder 257 is fixed to the main body frame 251, and the piston rod of the pushing cylinder 257 is fixed to the grabbing mechanism 256.

[0155] Specifically, the grabbing mechanism 256 comprises a transversely arranged cross arm 2561. Two ends of the cross arm 2561 are respectively provided with longitudinally arranged longitudinal arms 2562 extending horizontally towards the direction where the barrel position correcting device 254 is located. One end of the longitudinal arm 2562 is fixedly connected with the cross arm 2561, and the other end of the longitudinal arm 2562 is a free end. The longitudinal arm 2562 is perpendicular to the cross arm 2561.

[0156] A grabbing cylinder 2563 is fixed at the free end of the longitudinal arm 2562, and the grabbing cylinders 2563 at the free ends of the two longitudinal arms 2562 are mirror-symmetrically arranged. The piston rods of the two grabbing cylinders 2563 are opposite to each other. A grabbing claw 2564 is fixed at the end of the piston rod of the grabbing cylinder 2563. When the grabbing cylinder 2563 pushes the grabbing claw 2564 to move, the two grabbing claws 2564 move towards or away from each other. When the two grabbing claws 2564 move towards each other, the inner barrel can be grabbed from the outside of the inner barrel.

[0157] Specifically, the vertical moving stroke of the grabbing mechanism 256 comprises a first height point and a second height point, and the first height point is higher than the second height point. When the grabbing mechanism 256 moves downward to the second height point, the two grabbing claws 2564 of the grabbing mechanism 256 are lowered to a state of being horizontally opposite to the top of the inner barrel of the cooking pot placed on the barrel position correcting device 254. When the two grabbing claws 2564 move towards each other, the two grabbing claws 2564 can grab and fix the top of the inner barrel. When the grabbing mechanism 256 moves upward from the second height point to the first height point, the grabbing mechanism 256 lifts the inner barrel until the inner barrel is completely separated from the outer barrel of the cooking pot and the inner barrel is higher than the top of the outer barrel by a distance. When the grabbing mechanism 256 moves to the first height point, the grabbing mechanism 256 keeps grabbing the inner barrel and keeps the inner barrel in a suspended state for a period of time. When the inner barrel is lifted and kept in the suspended state for a period of time, the medicinal liquid in the inner barrel drips into the inner barrel of the outer barrel until the inner barrel stops dripping the medicinal liquid.

[0158] In the embodiment, two vertically arranged guide rails 258 are fixed on the side wall of the main frame 251 facing the barrel position correcting device 254, and the grabbing mechanism 256 is located between the two guide rails 258. A moving seat 259 is fixed on the side surface of the grabbing mechanism 256 opposite to the guide rails 258, the moving seat 259 is clamped on the guide rails 258 and can move along the length direction of the guide rails 258. The moving seat 259 is fixedly connected with the grabbing mechanism 256, and the connection between the moving seat 259 and the grabbing mechanism 256 can be achieved by welding or bolting.

[0159] When the push cylinder 257 pushes the grabbing mechanism 256 to move vertically, the moving base 259 moves along the guide rail 258. When the grabbing mechanism 256 moves, the grabbing mechanism 256 can move more stably, the vibration generated in the moving process of the grabbing mechanism 256 is reduced, and the stability of the inner barrel in the lifting or lowering process is ensured.

[0160] In the embodiment, the main frame 251 is further provided with a liquid receiving assembly 2510. The liquid receiving assembly 2510 comprises a horizontally placed liquid receiving disc 25101 and a rodless cylinder 25102 for driving the liquid receiving disc 25101 to move horizontally. The disc opening of the liquid receiving disc 25101 faces upward. The direction of the grabbing mechanism 256 is located in the moving direction of the liquid receiving disc 25101.

[0161] The rodless cylinder 25102 is horizontally fixed on the main frame 251. The moving direction of the external moving mechanism 251021 of the rodless cylinder 25102 is arranged from the side of the main frame 251 facing the first conveyor 252 to the side away from the first conveyor 252. The external moving mechanism 251021 of the rodless cylinder 25102 faces downward. The liquid receiving disc 25101 is located below the external moving mechanism of the rodless cylinder 25102. The liquid receiving disc 25101 is fixed on the external moving mechanism 251021 of the rodless cylinder 25102.

[0162] When the grabbing mechanism 256 grabs the inner barrel and moves to the first height point, the height of the liquid receiving disc 25101 is lower than the bottom end of the inner barrel. When the external moving mechanism of the rodless cylinder 25102 drives the liquid receiving disc 25101 to move to the direction of the grabbing mechanism 256, the liquid receiving disc 25101 moves to the position directly below the inner barrel. By arranging the liquid receiving disc 25101, when the outer barrel is removed from the barrel position correcting device 254 for pouring, the liquid receiving disc 25101 can catch the liquid medicine drops falling from the inner barrel in the suspended state, so as to prevent the liquid medicine from falling on the barrel position correcting device 254.

[0163] Preferably, a liquid discharge interface 251011 extending outward is arranged at the bottom of the liquid receiving disc 25101. The liquid discharge interface 251011 is connected with the containing space of the liquid receiving disc 25101. The liquid discharge interface 251011 is integrally formed with the liquid receiving disc 25101. In the use process of the liquid receiving disc 25101, the liquid discharge interface 251011 can be blocked or connected with a liquid guide pipe. If the liquid guide pipe is connected with the liquid discharge interface 251011, the liquid medicine flowing into the containing space of the liquid receiving disc 25101 can be directly discharged through the liquid discharge interface 251011 and the liquid guide pipe.

[0164] In the embodiment, the lower side of the liquid receiving tray 25101 is further provided with a partition plate 2511 which is horizontally fixed on the main body frame 251. A conveying space is left between the partition plate 2511 and the second conveying machine 253. When the second conveying machine 253 conveys the decoction pot, the decoction pot can pass below the partition plate 2511. The side of the partition plate 2511 which is away from the grabbing mechanism 256 is vertically downward projected on the outer side of the second conveying machine 253. The side of the partition plate 2511 which is away from the grabbing mechanism 256 is fixed with a transversely arranged guide wheel 25111, the axial direction of the guide wheel 25111 is perpendicular to the moving direction of the liquid receiving tray 25101. The outer circumferential surface of the guide wheel 25111 is provided with an annular groove 251111 which is arranged along the circumferential direction of the guide wheel 25111. When the liquid guide pipe is in communication with the liquid discharge interface 251011, the liquid guide pipe passes around the annular groove 251111 on the guide wheel 25111.

[0165] The liquid receiving tray 25101 has two position states, the first state is the extended state, i.e. the state that the liquid receiving tray 25101 is moved to the position right below the inner barrel by the rodless cylinder 25102. The second state is the retracted state, i.e. the state that the liquid receiving tray 25101 is retracted into the main body frame 251 by the rodless cylinder 25102. When the liquid receiving tray 25101 is in the retracted state, the liquid receiving tray 25101 is located right above the partition plate 2511. When the liquid receiving tray 25101 is in the extended state, the partition plate 2511 can hold the liquid guide pipe and avoid the liquid guide pipe falling down to the second conveying machine 253.

[0166] When the liquid medicine and residue are separated, the decoction pot with the liquid medicine is first placed on the barrel position correcting device 254, the barrel position correcting device 254 adjusts the horizontal position and vertical height of the decoction pot, so that the position of the decoction pot is moved to the pre-set position point. After the decoction pot is moved to the set position point, the pushing cylinder 257 drives the grabbing mechanism 256 to descend to the second height point, and the grabbing mechanism 256 grabs the inner barrel of the decoction pot. After the inner barrel is grabbed and fixed, the pushing cylinder 257 drives the grabbing mechanism 256 to ascend to the first height point. With the continuous ascending of the grabbing mechanism 256, the grabbing mechanism 256 lifts the inner barrel 12. When the grabbing mechanism 256 reaches the first height point, the inner barrel 12 is in a suspended and stationary state for a period of time. During the lifting of the inner barrel 12 and the period of time when the inner barrel 12 is in the suspended and stationary state, the liquid medicine in the inner barrel 12 drips into the outer barrel 11. The length of the time when the inner barrel 12 is in the suspended and stationary state needs to be ensured to prevent the inner barrel 12 from dripping the liquid medicine into the outer barrel 11.

[0167] The outer barrel 11 is taken off from the barrel position correction device 254, and the medicinal liquid in the outer barrel 11 is poured out or sent to the medicinal liquid filling mechanism 24 for packaging. After the medicinal liquid is taken out from the outer barrel 11, the outer barrel 11 is placed back on the barrel position correction device 254, and the barrel position correction device 254 adjusts the position of the outer barrel 11 to return the position of the outer barrel 11 to the set position.

[0168] After the position of the outer barrel 11 is adjusted to the specified position point by the barrel position correction device 254, the pushing cylinder 257 drives the grabbing mechanism 256 to descend to the second height point, and the grabbing mechanism 256 places the inner barrel back into the inner part of the outer barrel 11. After the inner barrel is placed back into the inner part of the outer barrel 11, the grabbing mechanism 256 releases the inner barrel, the pushing cylinder 257 drives the grabbing mechanism 256 to return to the first height point, and the separation between the medicinal liquid and the medicinal residue is completed.

[0169] The lifting platform 2542 of the barrel position correction device 254 is lowered to the lowest position, and the decoction pot falls on the conveying belt of the first conveyor 252, and the conveying belt of the first conveyor 252 drives the decoction pot to move to the downstream end of the first conveyor 252. If it is needed to transfer the decoction pot to the second conveyor 253, the decoction pot is transferred to the second conveyor 253 through the cooperation of the first lifting transfer machine 2521 and the second lifting transfer machine 2531.

[0170] When the medicinal materials are decocted and filled, the inner part of the decoction pot 1 is filled with medicinal materials and water, the double-column stacker crane 22 uses the fork to fork the decoction pot 1, and places the decoction pot 1 on the heating module 232 of the decoction mechanism 23. The decoction mechanism 23 heats the decoction pot 1 to decoct the medicinal materials and water in the decoction pot 1 into a traditional Chinese medicine decoction.

[0171] When the medicinal materials in the decoction pot 1 are decocted, the double-column stacker crane 22 uses the fork to fork the decoction pot 1, and places the decoction pot 1 on the barrel position correction device 254 of the static filtration mechanism 25. The grabbing mechanism 256 of the static filtration mechanism 25 lifts the inner barrel 12 of the decoction pot 1 out of the outer barrel 11 to separate the medicinal materials from the medicinal liquid, and the medicinal liquid remains in the inner part of the outer barrel 11. When the medicinal liquid in the inner barrel 12 is completely dropped into the outer barrel 11, the double-column stacker crane 22 forks the outer barrel 11, and sends the outer barrel 11 to the medicinal liquid filling mechanism 24 in the same group as the static filtration mechanism 25. The medicinal liquid in the outer barrel 11 is poured into the medicinal liquid filling mechanism 24, and the medicinal liquid filling mechanism 24 packages the medicinal liquid.

[0172] In the embodiment, the automatic micro-pressure circulation decocting traditional Chinese medicine production line further comprises a prescription binding station 5 located upstream of the decocting mechanism 23. The prescription binding station 5 is provided with a code scanning device and a processing device installed with a traditional Chinese medicine information management system. After the medicine bag is filled with medicine, the staff will paste an identification code on the outside of the filled medicine bag. The identification code can be a two-dimensional code or other identifiable identification code. An identification code can also be pasted on the barrel of the decocting pot 1. The identification code can be a two-dimensional code or other identifiable identification code.

[0173] When the decocting pot 1 is sent to the prescription binding station 5, the staff scans the identification code on the medicine bag and the identification code on the barrel of the decocting pot 1 through the code scanning device, and binds the information of the medicine bag and the decocting pot 1 through the processing device installed with the traditional Chinese medicine information management system. After the information of the medicine bag and the decocting pot 1 is bound, the staff opens the decocting pot 1 and puts the medicine bag into the inner barrel 12 of the bound decocting pot 1.

[0174] The circulation conveying line 4 comprises a first conveying section 41, a second conveying section 42 and a third conveying section 43. The upstream end of the first conveying section 41 is located at the prescription binding station 5, and the downstream end of the first conveying section 41 is connected with the track group 21 of the decocting and filling unit 2. The upstream end of the second conveying section 42 is connected with the downstream sections of the first conveyor 252 and the second conveyor 253 of the static filtering mechanism 25, and the downstream end of the second conveying section 42 is connected with the upstream end of the third conveying section 43. The downstream end of the third conveying section 43 is connected with the first conveying section 41. The third conveying section 43 passes through the cleaning unit 3.

[0175] In the embodiment, an automatic cover opening and closing machine 6 is arranged on one side of the first conveying section 41, which is used to open the barrel cover 13 of the decocting pot 1. A water adding device 7 is arranged on the other side of the first conveying section 41, which is used to add water to the inside of the decocting pot 1. The automatic cover opening and closing machine 6 and the water adding device 7 are located between the prescription binding station 5 and the decocting and filling unit 2. The automatic cover opening and closing machine 6 and the water adding device 7 are arranged oppositely. When the first conveying section 41 sends the decocting pot 1 to the automatic cover opening and closing machine 6, the automatic cover opening and closing machine 6 opens the barrel cover 13 of the decocting pot 1 and temporarily stores the barrel cover 13 on the automatic cover opening and closing machine 6. The water adding device 7 adds water to the inside of the decocting pot 1 with the opened barrel cover 13 until the added water reaches the set water amount.

[0176] A medicine soaking pressing machine 8 is further arranged on one side of the first conveying section 41, which is used to press the medicine bag in the decocting pot 1 multiple times. The medicine soaking pressing machine 8 is located between the water adding device 7 and the decocting and filling unit 2.

[0177] The micro-pressure circulation decocting traditional Chinese medicine automatic production line further comprises a medicine soaking conveying line 9 located downstream of the medicine soaking and pressing machine 8. The upstream end and the downstream end of the medicine soaking conveying line 9 are connected with the first conveying section 41. When the decocting pot 1 moves to the upstream end of the medicine soaking conveying line 9 through the first conveying section 41, the first conveying section 41 sends the decocting pot 1 to the medicine soaking conveying line 9, and the decocting pot 1 moves on the medicine soaking conveying line 9 to the downstream end of the medicine soaking conveying line 9. When the decocting pot 1 moves from the upstream end to the downstream end of the medicine soaking conveying line 9, the decocting pot 1 returns to the first conveying section 41 again and is sent to the decocting and filling unit 2 through the first conveying section 41.

[0178] The soaking time of the medicinal materials in the decocting pot 1 can be determined by setting the length and the conveying speed of the medicine soaking conveying line 9. The time taken for the decocting pot 1 to move from the upstream end to the downstream end of the medicine soaking conveying line 9 is the soaking time of the medicinal materials in the decocting pot 1.

[0179] Preferably, the medicine soaking conveying line 9 extends to the side of the automatic cover opening and closing machine 6 away from the first conveying section 41. When the decocting pot 1 moves to the automatic cover opening and closing machine 6 on the medicine soaking conveying line, the automatic cover opening and closing machine 6 covers the temporarily stored barrel cover back to the decocting pot 1.

[0180] In the embodiment, the cleaning unit 3 comprises a residue overturning machine 31, a pot brushing machine 32 and a cleaning machine 33 arranged in sequence. The flow transfer conveying line 4 further comprises a second conveying section 42 located downstream of the first conveying machine 252 and the second conveying machine 253 of the static filtering mechanism 25. The downstream end of the first conveying machine 252 and the downstream end of the second conveying machine 253 are connected with the second conveying section 42. The residue overturning machine 31, the pot brushing machine 32 and the cleaning machine 33 are arranged along the extension direction of the second conveying section 42. The residue overturning machine 31 is used to overturn the medicinal bag in the inner barrel 12 after decocting from the inner barrel 12. The pot brushing machine 32 and the cleaning machine 33 are used to clean the inner barrel 12 and the outer barrel 11 of the decocting pot 1 thoroughly.

[0181] In the embodiment, the cleaning unit 3 further comprises a barrel cover buffer line 34 on which the cleaned barrel cover is placed to be temporarily stored. The extension direction of the barrel cover buffer line 34 is parallel to the extension direction of the second conveying section 42. The barrel cover buffer line 34 is used to temporarily store the barrel cover 13. When the barrel cover 13 is placed on the barrel cover buffer line 34, the barrel cover buffer line 34 drives the barrel cover 13 to move to the downstream end of the barrel cover buffer line 34.

[0182] In the embodiment, a third conveying section 43 is arranged between the downstream end of the second conveying section 42 and the upstream end of the first conveying section 41, and the downstream end of the third conveying section 43 is connected to the upstream end of the first conveying section 41. After the decocting pot 1 is cleaned by the cleaning unit 3, the clean decocting pot 1 is sent back to the first conveying section 41 by the third conveying section 43 for repeated use.

[0183] In the embodiment, the heights of the first conveying section 41, the second conveying section 42 and the third conveying section 43 are different, and a lifting machine 44 is arranged between the second conveying section 42 and the third conveying section 43 and between the third conveying section 43 and the first conveying section 41, and the lifting machine 44 is used to change the height of the decocting pot 1.

[0184] When the decocting pot 1 is conveyed from the upstream end to the downstream end of the second conveying section 42, the decocting pot 1 enters the lifting machine 44, the lifting machine 44 adjusts the height of the decocting pot 1 to the height matched with the third conveying section 43, and sends the decocting pot 1 to the third conveying section 43. The decocting pot 1 sent to the third conveying section 43 moves from the upstream end of the third conveying section 43 to the downstream end of the third conveying section 43. When the decocting pot 1 moves to the downstream end of the third conveying section 43, the lifting machine 44 between the third conveying section 43 and the first conveying section 41 adjusts the height of the decocting pot 1 to the height matched with the first conveying section 41, and sends the decocting pot 1 to the first conveying section 41.
