Description

Technical Field

[0001] The present application relates to the pharmaceutical field, and in particular to a blister strip drug powder recovery device. Background Art

[0002] Powder inhalation refers to a drug dosage form in which one or more drug powders are loaded into a special drug delivery device and the drug is sprayed at the drug delivery site in the form of dry powder to exert systemic or local effects. The drug delivery devices for inhaled powder inhalation include capsule type, blister type and reservoir type. Among them, the strips produced by the adjustment before filling of blister type powder inhalation production are unqualified, and unqualified strips are also produced during the filling process. These strips also contain drug powder. Directly discarding these unqualified strips also causes waste of drug powder. Summary of the invention

[0003] The purpose of the embodiment of the present application is to provide a blister strip medicine powder recovery device for recovering medicine powder in a blister strip.

[0004] In a first aspect, an embodiment of the present application provides a blister strip drug powder recovery device, which includes a storage mechanism, a peeling mechanism, and a collection box. The storage mechanism is used to store a blister strip, and the blister strip includes a blister strip and a sealing strip that are relatively fitted. The peeling mechanism is used to peel off the blister strip and the sealing strip on the blister strip to release the drug powder in the blister strip. The collection box is used to collect the drug powder released after the blister strip is peeled off.

[0005] In this implementation, the operator stores the unqualified strips produced during the pre-filling machine adjustment and the filling process in a storage mechanism, and then peels off the sealing strip on the blister strip from the blister strip through a peeling mechanism, thereby exposing the collecting port of the blisters on the blister strip, releasing the medicine powder, and finally using a collection box to collect the medicine powder. The collected medicine powder can be recycled, reducing the waste of medicine powder and improving the utilization rate of medicine powder.

[0006] In a possible implementation, the storage mechanism includes a storage shaft, which can release or roll up the blister strip by rotation; the stripping mechanism includes a blister strip stripping shaft and a sealing strip stripping shaft, which can strip the blister strip by rotating and rolling up the blister strip and the sealing strip respectively.

[0007] In this implementation, before the operator starts to use the blister strip powder recovery device to recover the powder, he first rolls up the unqualified blister strip that needs to be recycled on the storage shaft, then manually peels off one end of the blister strip to a certain length, fixes one end of the blister strip to the blister strip stripping shaft, and fixes one end of the sealing strip to the sealing strip stripping shaft. After that, the blister strip stripping shaft and the sealing strip stripping shaft are started to rotate, the blister strip stripping shaft reels the blister strip, and the sealing strip stripping shaft cooperates to reel in the sealing strip, and then the blister strip is continuously peeled off, so that the powder in the blister strip is released and collected by the collection box. Based on the continuity of the blister strip and the sealing strip of the blister strip, the present application adopts multiple rotating shafts, namely the storage shaft, the blister strip stripping shaft and the sealing strip stripping shaft, to release the powder from the peeled blister strip in the form of rotating and reeling in the corresponding strips. The structure is simple, and the peeling process is stable and continuous.

[0008] In a possible implementation, the stripping mechanism further includes a tensioning shaft, one end of the blister strip is connected to the storage shaft, and the other end passes around the tensioning shaft and is stripped into the blister strip and the sealing strip.

[0009] In this implementation, a tensioning shaft is arranged between the storage shaft and the blister strip stripping shaft and the sealing strip stripping shaft, which can tension the blister strip so that the blister strip has a certain tension, ensuring the flatness of the blister strip before stripping, which is beneficial to improving the stability of the subsequent stripping of the blister strip.

[0010] In a possible implementation, the stripping mechanism further includes a stripping port limiting component, the stripping port limiting component is provided with a stripping channel, the blister strip passes through the stripping channel and is stripped at the end of the stripping channel; the collecting box is provided with a collecting port, the collecting port is located below the end of the stripping channel.

[0011] In this implementation, the blister strip is passed through the stripping channel on the stripping port limiting component and is stripped at the end of the stripping channel, that is, the stripping port limiting component is set to limit the stripping port of the blister strip at a specific position, and a collecting box is set below the stripping port of the blister strip, so that the collecting port of the collecting box is below the stripping port, so that most of the powder released at the stripping port of the blister strip can directly enter the collecting box under the action of gravity, effectively improving the recovery rate of the powder and reducing the dust pollution caused by the flying powder after the blister strip is stripped.

[0012] In a possible implementation, the stripping opening limiting assembly further includes a stripping guide and a rotatable stripping shaft, and the stripping guide and an outer wall of the stripping shaft are arranged relative to each other to form the stripping channel.

[0013] In this implementation, a stripping shaft and a stripping guide are provided to cooperate to define a stripping channel, which has a simple structure and is easy to implement. The blister strip passes through the stripping channel and contacts the stripping shaft, and the rotation of the stripping shaft can reduce the friction force on the blister strip and reduce the impact on the subsequent winding of the blister strip stripping shaft and the sealing strip stripping shaft.

[0014] In a possible implementation, a through hole is formed on a side of the collecting box away from the collecting port, and the blister strip passes through the collecting port and the through hole in sequence and is rolled up on the blister strip stripping shaft.

[0015] In this implementation, a collecting port and a through hole are opened on the collecting box, so that the blister strip after peeling off the blister strip can directly pass through the collecting box. Compared with opening a large collecting port directly at the upper end of the collecting box, the sealing of the collecting box is improved, and the time for the blister strip to pass through the collecting box is also prolonged, so that as much powder on the blister strip as possible can be collected in the collecting box, thereby improving the powder recovery rate.

[0016] In a possible implementation, the blister strip powder recovery device further includes a first guide shaft and a second guide shaft, wherein the first guide shaft and the second guide shaft are arranged in parallel with each other and configure a first guide channel, and the blister strip passes through the first guide channel and is rolled up on the blister strip stripping shaft.

[0017] In this implementation, a first guide shaft cooperates with a second guide shaft to form a first guide channel to guide the blister strip, thereby preventing the blister strip from flipping or angular deviation, so that the blister strip can be neatly rolled up on the blister strip stripping shaft.

[0018] In a possible implementation, the blister strip powder recovery device further includes a third guide shaft and a third guide shaft, wherein the third guide shaft and the third guide shaft are arranged in parallel with each other and are configured with a second guide channel, and the sealing strip passes through the second guide channel and is rolled up on the sealing strip stripping shaft.

[0019] In this implementation, the third guide shaft cooperates with the fourth guide shaft to form a second guide channel to guide the sealing strip, which can prevent the sealing strip from flipping or angular deviation, so that the sealing strip can be neatly rolled up on the sealing strip stripping shaft.

[0020] In a possible implementation, the blister strip medicine powder recovery device further includes a sealing box for sealingly accommodating the storage mechanism, the stripping mechanism, and the collection box.

[0021] In this implementation, the storage mechanism, the stripping mechanism and the collection box are arranged in a sealed box, so that the collection process of the medicine powder can be isolated from the outside world, thereby preventing dust from overflowing and polluting the environment.

[0022] In a possible implementation, the speed at which the receiving shaft releases the blister strip, the speed at which the blister strip stripping shaft reels the blister strip, and the speed at which the sealing strip stripping shaft reels the sealing strip are the same.

[0023] In this implementation, the speed at which the storage shaft releases the blister strip, the speed at which the blister strip stripping shaft reels the blister strip, and the speed at which the sealing strip stripping shaft reels the sealing strip are set to be the same, so that the strip portion between the storage shaft and the blister strip stripping shaft and the sealing strip stripping shaft can be kept tensioned, thereby improving the stability of blister strip stripping and the neatness of rewinding the blister strip stripping shaft and the sealing strip stripping shaft.

[0024] In a possible implementation, the stripping mechanism further includes a first driving member, a second driving member and a third driving member, wherein the first driving member is used to drive the storage shaft to rotate, the second driving member is used to drive the blister stripping shaft to rotate, and the third driving member is used to drive the sealing strip stripping shaft to rotate.

[0025] In this implementation, since the thicknesses of the blister strip, blister strip and sealing strip are inconsistent, the first drive member, the second drive member and the third drive member are provided to respectively drive the storage shaft, the blister strip stripping shaft and the sealing strip stripping shaft to rotate, and the rotation speeds of the output shafts of the first drive member, the second drive member and the third drive member can be adjusted according to the diameters of the storage shaft, the blister strip stripping shaft and the sealing strip stripping shaft and the thicknesses of the blister strip, the blister strip and the sealing strip, so that the speed at which the storage shaft releases the blister strip, the speed at which the blister strip stripping shaft reels the blister strip and the speed at which the sealing strip stripping shaft reels the sealing strip are the same.

[0031] The blister-type drug delivery device for powder aerosols generally includes a blister and a sealing sheet that seals the blister collection port. However, during the filling production process, the blister-type powder aerosol generally appears in the form of a strip. The blister strip includes a blister strip and a sealing strip that are relatively close together. Each blister strip includes a plurality of blisters connected in sequence for containing a certain amount of powder aerosol.

[0032] In the first aspect, the present application embodiment provides a drug powder recovery device for a blister strip 300, please refer to Figure 1 , Figure 1 This is a structural diagram of a blister strip drug powder recovery device provided in an embodiment of the present application. The blister strip 300 drug powder recovery device includes a storage mechanism 100, a peeling mechanism 200, and a collection box 400. The storage mechanism 100 is used to store the blister strip 300. The blister strip 300 includes a blister strip 310 and a sealing strip 320 that are relatively fitted. The peeling mechanism 200 is used to peel the blister strip 310 and the sealing strip 320 on the blister strip 300 to release the drug powder in the blister strip 300. The collection box 400 is used to collect the drug powder released after the blister strip 300 is peeled.

[0033] In this implementation, the operator stores the unqualified strips produced during the pre-filling adjustment and the filling process in the storage mechanism 100, and then peels off the sealing strip 320 on the blister strip 300 from the blister strip 310 through the peeling mechanism 200, thereby exposing the collecting port 410 of the blisters on the blister strip 310, releasing the powder, and finally uses the collection box 400 to collect the powder. The collected powder can be recycled, reducing the waste of powder and improving the utilization rate of powder.

[0034] In a possible implementation, the storage mechanism 100 includes a storage shaft 110, which can release or roll up the blister strip 300 by rotation; the stripping mechanism 200 includes a blister strip stripping shaft 210 and a sealing strip stripping shaft 220, which can strip the blister strip 300 by rotating and rolling up the blister strip 310 and the sealing strip 320 respectively.

[0035] In this implementation, before the operator starts to use the blister strip 300 powder recovery device to recover the powder, he first rolls the unqualified blister strip 300 that needs to be recycled on the storage shaft 110, and then manually peels off one end of the blister strip 300 for a certain length, fixes one end of the blister strip 310 to the blister strip stripping shaft 210, and fixes one end of the sealing strip 320 to the sealing strip stripping shaft 220, and then starts the blister strip stripping shaft 210 and the sealing strip stripping shaft 220 to rotate, the blister strip stripping shaft 210 reels the blister strip 310, and the sealing strip stripping shaft 220 cooperates to reel in the sealing strip 320, thereby continuously peeling off the blister strip 300, so that the powder in the blister strip 300 is released and collected by the collection box 400. The present application is based on the continuity of the blister strip 310 and the sealing strip 320 of the blister strip 300, and adopts multiple rotating shafts, namely the storage shaft 110, the blister strip stripping shaft 210 and the sealing strip stripping shaft 220, to release the powder from the blister strip 300 by rotating and winding the corresponding strips. The structure is simple and the stripping process is stable and continuous.

[0036] Optionally, a blister strip 310 collecting tray is provided on the blister strip stripping shaft 210 to ensure that the blister strip 310 is neatly rolled up. A blister strip 310 collecting tray is provided on the sealing strip stripping shaft 220 to ensure that the sealing strip 320 is neatly rolled up.

[0037] In a possible implementation, the stripping mechanism 200 further includes a tensioning shaft 230 , one end of the blister strip 300 is connected to the storage shaft 110 , and the other end passes around the tensioning shaft 230 and is stripped into a blister strip 310 and a sealing strip 320 .

[0038] In this implementation, a tensioning shaft 230 is arranged between the storage shaft 110 and the blister strip stripping shaft 210 and the sealing strip strip stripping shaft 220, which can tension the blister strip 300 so that the blister strip 300 has a certain tension, ensuring the flatness of the blister strip 300 before stripping, which is beneficial to improving the stability of the subsequent stripping of the blister strip 300.

[0039] In a possible implementation, the stripping mechanism 200 further includes a stripping opening limiting component 240, on which a stripping channel is provided, and the blister strip 300 passes through the stripping channel and is stripped at the end of the stripping channel; a collecting opening 410 is provided on the collecting box 400, and the collecting opening 410 is located below the end of the stripping channel.

[0040] In this implementation, the blister strip 300 is passed through the stripping channel on the stripping opening limiting component 240 and stripped at the end of the stripping channel, that is, the stripping opening limiting component 240 is set to limit the stripping opening of the blister strip 300 at a specific position, and a collecting box 400 is set below the stripping opening of the blister strip 300, so that the collecting opening 410 of the collecting box 400 is below the stripping opening, so that most of the medicine powder released at the stripping opening of the blister strip 300 can directly enter the collecting box 400 under the action of gravity, thereby effectively improving the recovery rate of the medicine powder and reducing the dust pollution caused by the flying medicine powder after the blister strip 300 is stripped.

[0041] It should be noted that the collection port 410 of the collection box 400 is located below the end of the stripping channel, including part or all of the collection port 410 of the collection box 400 is located below the end of the stripping channel.

[0042] In a possible implementation, the stripping opening limiting assembly 240 further includes a stripping guide 241 and a rotatable stripping shaft 242 , and the stripping guide 241 and the outer wall of the stripping shaft 242 are arranged opposite to each other to form a stripping channel.

[0043] In this implementation, the stripping shaft 242 and the stripping guide 241 are provided to cooperate to define the stripping channel, which has a simple structure and is easy to implement. The blister strip 300 passes through the stripping channel and contacts the stripping shaft 242. The rotation of the stripping shaft 242 can reduce the friction force on the blister strip 300 and reduce the impact on the subsequent winding of the blister strip stripping shaft 210 and the sealing strip stripping shaft 220.

[0044] Optionally, the stripping shaft 242 is a hollow shaft to prevent the blister strip 300 from being crushed.

[0045] Optionally, the thickness of the peeling channel is adapted to the thickness of the blister strip 300 . Specifically, the thickness of the peeling channel is equal to or slightly greater than the thickness of the blister strip 300 , so as to prevent the blister strip 300 from actively detaching from the peeling channel.

[0046] In a possible implementation, the stripping guide 241 is provided with an arcuate surface matched with the outer wall of the stripping shaft 242 , and the arcuate surface is arranged opposite to the outer wall of the stripping shaft 242 to form an annular stripping channel.

[0047] In this implementation, the opposing surfaces of the stripping guide 241 and the outer wall of the stripping shaft 242 are arc-shaped surfaces, forming an annular stripping channel. Therefore, the blister strip 300 passes through the stripping channel along the outer wall of the stripping shaft 242, thereby guiding the blister strip 300, allowing the blister strip 300 to be accurately stripped at the end of the stripping channel, thereby improving the accuracy of positioning the stripping port.

[0048] In a possible implementation, the stripping guide 241 can move closer to or farther from the stripping shaft 242 , thereby achieving the assembly and disassembly of the blister strip 300 .

[0049] Specifically, before recycling, when the blister strip 300 needs to pass through the stripping channel, the stripping guide 241 is moved away from the stripping shaft 242, the blister strip 300 is placed along the outer wall of the stripping shaft 242, and then the stripping guide 241 is moved close to the stripping shaft 242 to limit the blister strip 300.

[0050] Optionally, a swing arm is connected to the stripping guide 241, and one end of the swing arm away from the stripping guide 241 is fixedly mounted on other components of the drug powder recovery device of the blister strip 300, or mounted on a wall or a workbench. The number of the swing arm can be one section or multiple sections. When the swing arm has multiple sections, the multiple sections of the swing arm are connected in sequence.

[0051] In some possible implementations, the blister strip stripping axis 210 is parallel to the stripping rotating axis 242 and at the same height, so that the opening of the blister on the blister strip 310 is directed directly downward, that is, the direction of the opening is parallel to the vertical direction, which can promote the falling of the powder in the blister and reduce the residue of the powder in the blister.

[0052] In some possible implementations, the stripping shaft 242 is parallel to the tensioning shaft 230 , and the stripping shaft 242 is directly below the tensioning shaft 230 , so that the blister strip 300 enters the stripping channel vertically.

[0053] In a possible implementation, a through hole 420 is formed on a side of the collecting box 400 away from the collecting opening 410 , and the blister strip 310 passes through the collecting opening 410 and the through hole 420 in sequence and is rolled up on the blister strip stripping shaft 210 .

[0054] In this implementation, a collecting port 410 and a through hole 420 are provided on the collecting box 400, so that the blister strip 310 after the blister strip 300 is peeled off can directly pass through the collecting box 400. Compared with directly providing a large collecting port 410 at the upper end of the collecting box 400, the sealing performance of the collecting box 400 is improved, and the time for the blister strip 310 to pass through the collecting box 400 is also prolonged, so that as much powder as possible on the blister strip 310 can be collected in the collecting box 400, thereby improving the powder recovery rate.

[0055] Optionally, the size of the collecting port 410 and the size of the through hole 420 are adapted to the size of the blister strip 300. For example, the length of the through hole 420 is equal to or slightly greater than the width of the blister strip 300, and the height of the through hole 420 is equal to or slightly greater than the thickness of the blister strip 300. The horizontal extension area of ​​the collecting port 410 is equal to or slightly greater than the extension area of ​​one blister.

[0056] In a possible implementation, the drug powder recovery device of the blister strip 300 further includes a first guide shaft 251 and a second guide shaft 252 , which are arranged in parallel with each other and form a first guide channel, and the blister strip 310 passes through the first guide channel and is rolled up on the blister strip stripping shaft 210 .

[0057] In this implementation, the first guide shaft 251 cooperates with the second guide shaft 252 to form a first guide channel to guide the blister strip 310 , thereby preventing the blister strip 310 from flipping over or deviating in angle, so that the blister strip 310 can be neatly rolled up on the blister strip stripping shaft 210 .

[0058] In some embodiments, the first guide shaft 251 can move closer to or farther away from the second guide shaft 252 , thereby achieving assembly and disassembly of the blister strip 310 .

[0059] Optionally, more than one swing arm is connected to the first guide shaft 251 or the second guide shaft 252, and one end of the swing arm away from the first guide shaft 251 or the second guide shaft 252 is fixedly mounted on other components of the drug powder recovery device of the blister strip 300, or mounted on a wall or a workbench. The number of the swing arm can be one or more sections, and when the swing arm has multiple sections, the multiple sections of the swing arm are connected in sequence.

[0060] In a possible implementation, the drug powder recovery device of the blister strip 300 further includes a third guide shaft and a third guide shaft, the third guide shaft and the third guide shaft are arranged in parallel with each other and configured with a second guide channel, and the sealing strip 320 passes through the second guide channel and is rolled up on the sealing strip stripping shaft 220.

[0061] In this implementation, a third guide shaft cooperates with a fourth guide shaft to form a second guide channel to guide the sealing strip 320 , thereby preventing the sealing strip 320 from flipping or angularly deviating, so that the sealing strip 320 can be neatly rolled up on the sealing strip peeling shaft 220 .

[0062] In some embodiments, the third guide axis may be closer to or farther away from the fourth guide axis, thereby achieving assembly and disassembly of the blister strip 310 .

[0063] Optionally, one or more swing arms are connected to the third guide shaft or the fourth guide shaft, and one end of the swing arm away from the third guide shaft or the fourth guide shaft is fixedly mounted on other components of the blister strip 300 powder recovery device, or mounted on a wall or a workbench.

[0064] In a possible implementation, the drug powder recovery device of the blister strip 300 further includes a sealing box 500 for sealing and accommodating the storage mechanism 100 , the stripping mechanism 200 and the collection box 400 .

[0065] In this implementation, the storage mechanism 100, the stripping mechanism 200 and the collection box 400 are arranged in a sealed box 500, so that the collection process of the medicine powder can be isolated from the outside world, thereby preventing dust from overflowing and polluting the environment.

[0066] In a possible implementation, the drug powder recovery device of the blister strip 300 also includes a gear assembly 270 and a driving member; a first gear 261 is provided on the blister strip stripping shaft 210, and a second gear 262 is provided on the sealing strip stripping shaft 220, and the first gear 261, the gear assembly 270 and the second gear 262 are meshed in sequence; the driving member is used to drive the first gear 261, the second gear 262 or one of the gear assembly 270 to rotate.

[0067] In this implementation, a gear assembly 270 is provided to mesh with the first gear 261 and the second gear 262, so as to realize the linkage between the blister strip stripping shaft 210 and the sealing strip stripping shaft 220. When the driving member drives the gear assembly 270 and one of the first gear 261 and the second gear 262 to rotate, the synchronous rotation of the blister strip stripping shaft 210 and the sealing strip stripping shaft 220 can be realized.

[0068] In a possible implementation, the gear assembly 270 includes a third gear 271 , which is disposed on the stripping shaft 242 , and the driving member is connected to the stripping shaft 242 to drive the stripping shaft 242 to rotate.

[0069] In a possible implementation, the driving member is connected to the stripping shaft 242 to drive the stripping shaft 242 to rotate.

[0070] In a possible implementation, the gear assembly 270 further includes a fourth gear 272 , and the fourth gear 272 is meshed with the third gear 271 and the first gear 261 , respectively.

[0071] In the above implementation process, the fourth gear 272 is set between the third gear 271 and the first gear 261, which can increase the distance between the stripping shaft 242 and the blister strip stripping shaft 210, that is, increase the distance between the stripping port of the blister strip 300 and the winding position of the blister strip 310, so that the powder on the blister strip 310 has enough time to fall from the blister strip 310, and avoid the stripping port of the blister strip 300 and the winding position of the blister strip 310 being too close, so that part of the powder on the blister strip 310 does not fall but is directly wound up, thereby improving the powder recovery rate.

[0072] In a possible implementation, the first gear 261 on the blister strip stripping shaft 210 is directly meshed with the second gear 262 on the sealing strip stripping shaft 220 .

[0073] In a possible implementation, the speed at which the receiving shaft 110 releases the blister strip 300 , the speed at which the blister strip stripping shaft 210 rolls up the blister strip 310 , and the speed at which the sealing strip stripping shaft 220 rolls up the sealing strip 320 are the same.

[0074] In this implementation, the speed at which the storage shaft 110 releases the blister strip 300, the speed at which the blister strip stripping shaft 210 reels the blister strip 310, and the speed at which the sealing strip stripping shaft 220 reels the sealing strip 320 are set to be the same, so that the strip portion between the storage shaft 110 and the blister strip stripping shaft 210 and the sealing strip strip stripping shaft 220 can be kept taut, thereby improving the stability of the stripping of the blister strip 300 and the neatness of the reeling of the blister strip stripping shaft 210 and the sealing strip stripping shaft 220.

[0075] In a possible implementation, the stripping mechanism 200 further includes a first driving member, a second driving member and a third driving member, wherein the first driving member is used to drive the storage shaft 110 to rotate, the second driving member is used to drive the blister stripping shaft 210 to rotate, and the third driving member is used to drive the sealing strip stripping shaft 220 to rotate.

[0076] In this implementation, since the thicknesses of the blister strip 300, the blister strip 310 and the sealing strip 320 are inconsistent, a first driving member, a second driving member and a third driving member are provided to respectively drive the storage shaft 110, the blister strip stripping shaft 210 and the sealing strip strip stripping shaft 220 to rotate, and the rotation speeds of the output shafts of the first driving member, the second driving member and the third driving member can be adjusted according to the diameters of the storage shaft 110, the blister strip stripping shaft 210 and the sealing strip strip stripping shaft 220 and the thicknesses of the blister strip 300, the blister strip 310 and the sealing strip 320, so that the speed at which the storage shaft 110 releases the blister strip 300, the speed at which the blister strip stripping shaft 210 reels the blister strip 310 and the speed at which the sealing strip strip stripping shaft 220 reels the sealing strip 320 are the same.

[0077] Optionally, after the blister strip 300 is installed in place, the first driving member, the second driving member and the third driving member are started to operate the storage shaft 110, the blister strip stripping shaft 210 and the sealing strip strip stripping shaft 220, and the rotation speed is adjusted to observe whether there is any medicine powder in the blister strip 310 behind the collection box 400 that has not been collected by the collection box. If so, the rotation speed is slowed down to extend the time that the blister strip 310 hovers in the collection box 400.

[0078] In a possible implementation, the drug powder recovery device of the blister strip 300 further includes an automatic control system for controlling the operating states of the storage mechanism 100 and the stripping mechanism 200 .

[0079] Specifically, a sensing probe is provided in the collection box 400 for detecting the height of the medicine powder in the collection box 400. When the height of the medicine powder in the collection box 400 reaches a predetermined height, the automatic control system controls the storage mechanism 100 and the stripping mechanism 200 to stop operating, so as to facilitate the cleaning and recovery of the medicine powder.
