Description

Technical Field

[0001] This invention relates to the field of pneumatic conveyors, specifically to a pneumatic pipeline conveyor for metering and dispensing broken-cell wall Phellinus linteus powder and its usage method. Background Technology

[0002] In the pharmaceutical, food, and health product processing industries, high-value-added ultrafine powder materials such as broken-cell wall Ganoderma lucidum spore powder and broken-cell wall Phellinus linteus powder are often transported and metered through pneumatic pipelines. Because these powders have small particle sizes (typically in the micrometer range), large specific surface areas, and are prone to electrostatic adsorption and agglomeration, they are highly susceptible to bridging, adhesion, or even complete blockage at pipe corners or bends during pneumatic conveying. This leads to transport interruptions, reduced production efficiency, difficult cleaning, and significant material waste.

[0003] To address the aforementioned problems, various anti-clogging pneumatic pipeline conveying devices have been proposed in the prior art. For example, Chinese patent CN117228339B discloses a pneumatic pipeline conveyor for powdered materials, which uses retractable material-distributing plates at the bends of the conveying pipeline to separate accumulated materials into layers before gradually dispersing them. While this solution can alleviate clogging to some extent, it still has the following shortcomings: The material distribution sealing plate needs to be directly inserted into the material column. For highly viscous ultrafine powders, problems such as the plate getting stuck, being unable to exit, or powder leakage due to wear at the sealing interface are likely to occur. This solution is mainly for temporary unblocking of a single conveying channel and lacks a multi-channel redundancy design. Online cleaning and recycling of blocked channels without stopping the machine would affect the normal conveying of powder.

[0004] In the long-term continuous operation of existing pneumatic conveying systems, the single conveying channel will inevitably become blocked due to the gradual accumulation of powder. Once a blockage occurs, it is usually necessary to stop the machine for disassembly and cleaning, which affects the continuity and efficiency of the packaging operation. Some solutions attempt to set up a backup channel, but when switching channels, the residual blockage powder in the original channel can easily be carried into the sealing interface of the switching mechanism, causing accelerated wear and leading to seal failure. Summary of the Invention

[0005] The purpose of this invention is to provide a pneumatic pipeline conveyor and its method of use for metering and dispensing broken-cell wall Phellinus linteus powder, in order to solve the problems mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: A pneumatic pipeline conveyor for metering and dispensing broken-cell wall Phellinus linteus powder, comprising a conveying pipeline support, a horizontal pipe for conveying powder fixedly installed on the conveying pipeline support, the horizontal pipe being arranged horizontally, its air inlet end being connected to a Roots blower, a hopper being arranged above the horizontal pipe and perpendicular to its axis, a vertical pipe being connected to the conveying end of the horizontal pipe, the vertical pipe being connected to an external metering and dispensing machine, and an anti-clogging arc-shaped reversing component being disposed at the connection between the horizontal pipe and the vertical pipe.

[0006] Preferably, the anti-clogging arc-shaped reversing component includes a conveying arc-shaped frame fixedly mounted on the conveying pipe support. The conveying arc-shaped frame has an inlet and an outlet, wherein the inlet is sealed and connected to the output end of the horizontal pipe, and the outlet is sealed and connected to the inlet end of the vertical pipe. An arc-shaped pipe is slidably fitted inside the conveying arc-shaped frame, and the bending radius of the arc-shaped pipe matches that of the conveying arc-shaped frame. A partition plate is fixedly mounted at the center of the arc-shaped pipe along its arc length direction. The partition plate divides the internal cavity of the arc-shaped pipe into two independent and symmetrically arranged conveying channels. Each conveying channel has an opening at its inlet end and an outlet end corresponding to the inlet and outlet of the conveying arc-shaped frame, respectively. Anti-clogging components are also respectively mounted on the outer walls of both sides of the arc-shaped pipe.

[0007] Preferably, the connection anti-blocking component includes two fixed sleeves fixedly installed on the outer wall of the arc-shaped pipe. The two fixed sleeves are distributed at intervals along the arc of the arc-shaped pipe and are slidably engaged with the corresponding side wall of the conveying arc frame. A sealing gasket is provided at the connection between each fixed sleeve and the arc-shaped pipe. A frame-shaped steel bar with a semi-open frame structure is provided inside the arc-shaped pipe at the position corresponding to the independent conveying channel. The open end of the frame-shaped steel bar passes through the arc-shaped pipe, the sealing gasket and the fixed sleeve in sequence, and then extends outward and is fixedly connected to the support of the conveying pipe.

[0008] Preferably, a pressure vibration frame is slidably fitted on the outer circumferential wall of the fixed sleeve. The inner wall of the pressure vibration frame is elastically connected to the outer wall of the fixed sleeve by a connecting spring. One end of the pressure vibration frame abuts against a sealing gasket, and the other end is connected to a vibration locking component.

[0009] Preferably, the vibration locking component includes a sliding frame slidably disposed on the conveying pipe support. The outer wall of the sliding frame is fixedly connected to the end of the corresponding fixed sleeve through a fixing bracket. A sliding guide groove is provided on the sliding frame. A guide side plate is slidably installed in the sliding guide groove. The guide side plate is fixedly connected to a pressure vibration frame slidably sleeved on the outer wall of the fixed sleeve. A through groove extending along its length is also provided on the guide side plate, and a sliding roller is rotatably disposed at the end of the through groove.

[0010] Preferably, the conveying pipe support is further provided with a driving device, the movable output end of the driving device is fixedly connected to a bearing plate, the bearing plate is slidably guided with the conveying pipe support, a fixed insert shaft is fixedly installed on the bearing plate, a plug-in plate is fixedly connected on the fixed insert shaft, the plug-in plate has a symmetrical structure with the fixed insert shaft as the axis point, and continuous guide grooves extending in a wave curve are respectively opened on both sides of it.

[0011] Preferably, a triangular baffle with an equilateral triangle profile is fixedly provided at the center of the sliding frame, and a triangular adjusting frame is rotatably mounted on the fixed insert shaft. The adjusting frame is provided with two guide rollers, which roll in cooperation with the inner wall of the sliding frame. An extension plate is also fixedly connected to the adjusting frame, and the extension plate is elastically connected to the bearing plate by a tension spring. Two stop posts are symmetrically arranged on the bearing plate with the adjusting frame as the center. An abutment plate is also fixedly provided on the inner top of the sliding frame.

[0012] Preferably, the conveying arc frame is also provided with a collection groove, which is located below the middle part of the conveying arc frame. The conveying arc frame is provided with a slot that is connected to the collection groove along its middle area. The arc pipe is provided with a material drop port corresponding to the bottom position of each conveying channel. The conveying pipe support is also provided with a spiral feeding rod that is connected to the collection groove.

[0013] Preferably, the method of using the pneumatic pipeline conveyor for metering and dispensing broken-cell wall Phellinus linteus powder includes the following steps: S1: Start the Roots blower to make the airflow flow horizontally along the horizontal pipe. The powder falls from the hopper into the horizontal pipe, is carried by the airflow through the inlet into the conveying channel at the current working position, and then enters the vertical pipe through the outlet to complete the powder conveying. S2: When it is necessary to switch the conveying channel, start the drive device to move the bearing plate and the plug plate in the vertical direction, so that the plug plate separates from the guide side plate on the side of the current working state. During the separation process, the wave-shaped continuous guide groove and the sliding roller make intermittent contact, causing the pressure shaking frame to shake slightly along the axis of the fixed sleeve. The shaking is transmitted to the side wall of the arc-shaped pipe through the sealing gasket, shaking off the attached powder. S3: The drive unit operates, and through the cooperation of the adjusting frame and the triangular baffle, the sliding frame drives the fixed sleeve and the arc-shaped pipe to slide within the conveying arc frame, moving another conveying channel to a position aligned with the inlet and outlet, thus completing the switching of the conveying channel; S4: During the sliding process of the arc-shaped pipe, the stationary frame steel bar and the arc-shaped pipe are relatively displaced, scraping and breaking the arch in the original conveying channel, pushing away the blocked powder. At the same time, the material drop port at the bottom of the conveying channel, which has been switched to the non-working position, is aligned with the slot on the conveying arc frame, so that the residual powder falls into the collection tank and is forcibly discharged by the spiral feed rod. S5: After the switch is completed, the plug plate is reinserted into the through groove of the new working side guide plate. The raised part of the wavy continuous guide groove squeezes the sliding roller, so that the pressure shaking frame maintains a constant pressure on the sealing gasket and restores the sealed conveying state.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, one end of the frame-shaped steel bar is fixed to the support of the conveying pipe, and the other end is attached to the inner wall of the arc-shaped pipe. When the arc-shaped pipe moves laterally to switch channels, the stationary frame-shaped steel bar and the moving arc-shaped pipe generate relative displacement, thereby forming a direct scraping and arch-breaking effect on the inner wall of the original conveying channel, pushing and peeling away the blocked powder. This arch-breaking method is completed synchronously with the sliding switching action, without the need for additional power, and the structure is compact and the effect is direct.

[0015] In this invention, a plug-in plate and its wavy continuous guide groove are provided in the vibration locking component, which form a rolling engagement with the sliding roller on the guide side plate. Before switching the conveying channel, the wavy guide groove and the sliding roller make intermittent contact during the withdrawal of the plug-in plate, causing the pressure vibration frame to vibrate at high frequency and micro amplitude along the axis of the fixed sleeve. The vibration shakes off the residual powder adhering to the sealing gasket and the surface of the frame steel strip, preventing the powder from being carried into the sealing interface during the subsequent sliding process, causing wear or leakage. On the other hand, the vibration is transmitted to the side wall of the arc-shaped pipe, which helps to break up the powder bridging or adhesion blockage that has been formed in advance.

[0016] In this invention, a sealing gasket is set at the connection between the fixed sleeve and the arc-shaped pipe. Through the cooperation of the pressure shaking frame, the connecting spring and the corrugated guide groove of the plug plate, a constant clamping force is applied to the sealing gasket under normal conveying conditions, which effectively prevents powder from leaking out along the movable gap between the frame steel bar and the arc-shaped pipe. The sealing force is briefly released by shaking before switching and restored after switching, realizing the dynamic adaptation of the sealing state in the two stages of conveying and switching.

[0017] In this invention, the triangular baffle, the abutment plate, and the tension spring realize the timing control of the switching between upward deflection and downward push. The entire process of first shaking and cleaning and then channel switching is completed only through the lifting action, which is suitable for anti-static production environments in the powder conveying process.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example Please see Figures 1 to 12 The present invention provides a technical solution: a pneumatic pipeline conveyor for metering and dispensing broken-cell mulberry powder, including an anti-clogging arc reversing component 2, which solves the problems of powder blockage and cleaning difficulties in a single conveying channel during long-term operation, as well as powder jamming when switching channels.

[0022] The anti-clogging arc-shaped reversing component 2 is integrated into the conveying system. The conveying system includes a conveying pipe support 1. A horizontal pipe 11 for conveying powder is fixedly installed on the conveying pipe support 1. The horizontal pipe 11 is arranged horizontally, and its air inlet end is connected to a Roots blower 12 to provide a conveying air source. A hopper 13 is arranged above the horizontal pipe 11 and perpendicular to its axis to feed powder material into the horizontal pipe 11. The conveying end of the horizontal pipe 11 is connected to a vertical pipe 14, which is connected to an external metering and dispensing machine. The anti-clogging arc-shaped reversing component 2 is configured at the connection between the horizontal pipe 11 and the vertical pipe 14 to make the airflow carrying powder smoothly transition from the horizontal direction to the vertical direction.

[0023] Specifically, the anti-clogging arc-shaped reversing assembly 2 includes a conveying arc-shaped frame 21 fixedly mounted on the conveying pipe support 1. The conveying arc-shaped frame 21 has an inlet 211 and an outlet 212. The inlet 211 is sealed and connected to the output end of the horizontal pipe 11, and the outlet 212 is sealed and connected to the inlet end of the vertical pipe 14. An arc-shaped pipe 22 is slidably fitted inside the conveying arc-shaped frame 21. The bending radius of the arc-shaped pipe 22 matches that of the conveying arc-shaped frame 21. The center of the arc-shaped pipe 22 is along... A central partition 23 is fixedly installed along the arc length direction. The central partition 23 divides the internal cavity of the arc-shaped pipe 22 into two independent and symmetrically arranged conveying channels 24. Each conveying channel 24 has an opening 25 at its inlet end and an outlet end that corresponds to the inlet 211 and outlet 212 of the conveying arc frame 21. The outer walls on both sides of the arc-shaped pipe 22 are also respectively provided with connecting anti-blocking components 3, which are used to achieve sealing vibration and blockage removal while switching conveying channels 24. After the powder falls from the hopper 13 into the horizontal pipe 11, it is carried by the airflow of the Roots blower 12 into the inlet 211 of the conveying arc frame 21. In the initial state, the arc pipe 22 selects one of the two conveying channels 24 as needed, so that the openings 25 at both ends are aligned with the inlet 211 and outlet 212 of the conveying arc frame 21, respectively, thereby forming a continuous powder flow path. The powder enters the vertical pipe 14 through the selected conveying channel 24 and is finally sent to the metering and dispensing machine.

[0024] Based on this, let's take one of the anti-blocking components 3 as an example to illustrate its function. The anti-blocking component 3 includes two fixed sleeves 31 fixedly installed on the outer wall of the arc-shaped pipe 22. The two fixed sleeves 31 are distributed at intervals along the arc of the arc-shaped pipe 22 and are slidably engaged with the corresponding side wall of the conveying arc frame 21. Each fixed sleeve 31 is provided with a sealing gasket 32 ​​at the connection between it and the arc-shaped pipe 22 to prevent powder from leaking out along the moving gap. Inside the arc-shaped pipe 22, at the position corresponding to the independent conveying channel 24, there is a frame-shaped steel bar 33 with a semi-open frame structure. The open end of the frame-shaped steel bar 33 passes through the arc-shaped pipe 22, the sealing gasket 32 ​​and the fixed sleeve 31 in sequence, and then extends outward and is fixedly connected to the conveying pipe support 1. That is, the frame-shaped steel bar 33 is stationary relative to the conveying pipe support 1, while the arc-shaped pipe 22 can slide along its outer wall. Under normal conveying conditions, the frame-shaped steel bar 33 is attached to the inner wall of the arc-shaped pipe 22 and does not interfere with the normal passage of powder. A pressure shaking frame 34 is slidably sleeved on the outer circumferential wall of the fixed sleeve 31. The inner wall of the pressure shaking frame 34 is elastically connected to the outer wall of the fixed sleeve 31 by a connecting spring 35. One end of the pressure shaking frame 34 abuts against the sealing gasket 32, and the other end is connected to the shaking locking component 4. The vibration locking component 4 includes a sliding frame 41 slidably disposed on the conveying pipe support 1. The outer wall of the sliding frame 41 is fixedly connected to the end of the corresponding fixed sleeve 31 through a fixed frame. A sliding guide groove 411 is provided on the sliding frame 41. A guide side plate 42 is slidably installed in the sliding guide groove 411. The guide side plate 42 is fixedly connected to the pressure vibration frame 34 slidably sleeved on the outer wall of the fixed sleeve 31. A through groove 421 extending along its length is also provided on the guide side plate 42. A sliding roller 422 is rotatably disposed at the end of the through groove 421. A drive device 5 is also provided on the conveying pipe support 1. The drive device 5 is preferably a screw slide module. The movable output end of the drive device 5 is fixedly connected to a bearing plate 51. The bearing plate 51 slides and guides the conveying pipe support 1. A fixed insert shaft 52 is fixedly installed on the bearing plate 51. A plug-in plate 53 is fixedly connected on the fixed insert shaft 52. The plug-in plate 53 has a symmetrical structure with the fixed insert shaft 52 as the axis point. Continuous guide grooves 54 extending in a wave curve are opened on both sides of the plug-in plate 53. When the plug-in plate 53 moves inside the sliding frame 41, it can pass through the through groove 421 on the corresponding guide side plate 42 and keep the wave-shaped continuous guide groove 54 in rolling contact with the sliding roller 422. When it is necessary to switch the conveying channel 24, the drive device 5 drives the bearing plate 51 and the fixed insertion shaft 52 to move along the vertical direction of the conveying pipe support 1. The insertion plate 53 first separates from the guide side plate 42 on the side currently in operation. During the separation process, the wave-shaped continuous guide groove 54 and the sliding roller 422 make intermittent contact, thereby causing the pressure shaking frame 34 to vibrate slightly along the axis of the fixed sleeve 31. The vibration is transmitted to the side wall of the arc-shaped pipe 22 through the sealing gasket 32. On the one hand, it shakes off the residual powder attached to the sealing gasket 32 ​​to prevent the powder from being carried into the sealing interface during the subsequent sliding process, causing wear or leakage. On the other hand, the vibration is transmitted to the inner wall of the conveying channel 24, which helps to break up the powder bridging or adhesion blockage that has been formed in advance. Subsequently, the sliding frame 41 moves horizontally, causing the fixed sleeve 31 to drive the arc-shaped pipe 22 to slide within the conveying arc frame 21, thereby moving another unused conveying channel 24 to a position aligned with the inlet 211 and outlet 212, achieving uninterrupted conveying. During the above switching process, the originally stationary frame steel bar 33 and the arc-shaped pipe 22 undergo relative displacement, thereby scraping and breaking the arch on the inner wall of the original conveying channel 24, pushing and peeling away the blocked powder. Under normal conveying conditions, the plug plate 53 on one side of the selected conveying channel 24 is inserted into the corresponding through groove 421. The protruding part of the wave-shaped continuous guide groove 54 squeezes the sliding roller 422, so that the pressure shaking frame 34 maintains a constant clamping force on the sealing gasket 32, thereby effectively preventing powder leakage along the gap between the frame steel bar 33 and the arc-shaped pipe 22 during powder conveying.

[0025] In this embodiment, in order to achieve automatic reversal during the switching process, a triangular baffle 6 with an equilateral triangle outline is fixedly provided at the center of the sliding frame 41, and a triangular adjustment frame 61 is rotatably installed on the fixed insertion shaft 52. The adjustment frame 61 is provided with two guide rollers 62, which roll in cooperation with the inner wall of the sliding frame 41. An extension plate 63 is also fixedly connected to the adjustment frame 61. The extension plate 63 is elastically connected to the bearing plate 51 by a tension spring 64. Two stop posts 65 are symmetrically provided on the bearing plate 51 with the adjustment frame 61 as the center, which are used to limit the deflection angle of the adjustment frame 61. Under the preload of the tension spring 64, the adjusting frame 61 maintains an inclined posture, so that the inclined side of the adjusting frame 61 can contact the corresponding side of the triangular baffle 6. An abutment plate 66 is also fixedly provided on the inner top of the sliding frame 41.

[0026] When the drive device 5 drives the bearing plate 51 and the fixed insert shaft 52 to rise, the guide rollers 62 on the adjusting frame 61 roll upward along the inner wall of the sliding frame 41. When the guide rollers 62 contact the abutment plate 66 at the top of the sliding frame 41, under the limiting action of the abutment plate 66, the adjusting frame 61 is forced to deflect around the fixed insert shaft 52, and at the same time, it drives the extension plate 63 to move against the elastic force of the tension spring 64. When the adjusting frame 61 deflects into place, the tension spring 64 provides a reset preload force. At this time, the two guide rollers 62 on the adjusting frame 61 deflect to the other side of the sliding frame 41, driving... When the moving device 5 drives the bearing plate 51 to move down, the adjusting frame 61 first contacts the inclined side of the triangular baffle 6. Under the guidance of the inclined surface, the triangular baffle 6 drives the entire sliding frame 41 to slide horizontally, thereby driving the fixed sleeve 31 to complete the automatic switching of the arc-shaped pipe 22 to the conveying channel 24. After the switching is completed, the inner wall of the sliding frame 41 and the two guide rollers 62 on the adjusting frame 61 re-form a stable contact, and ensure that the guide side plate 42 and the plug plate 53 are accurately plugged in, so that the pressure shaking frame 34 can press the sealing gasket 32 ​​at the corresponding conveying channel 24 again.

[0027] In this embodiment, a collection trough 7 is also provided on the conveying arc frame 21. The collection trough 7 is located below the middle part of the conveying arc frame 21. The conveying arc frame 21 has a slot 71 that is connected to the collection trough 7 along its middle region. A material drop port 72 is provided on the arc pipe 22 corresponding to the bottom position of each conveying channel 24. A spiral feeding rod 73 connected to the collection trough 7 is also provided on the conveying pipe support 1 to force the blockage material falling into the collection trough 7 to the outside.

[0028] When one of the conveying channels 24 in the arc-shaped pipe 22 becomes blocked and is switched to a non-working position, the discharge port 72 at the bottom of the conveying channel 24 is aligned with the slot 71 on the conveying arc frame 21, so that the residual or blocking powder in the conveying channel 24 falls into the collection tank 7 and is discharged in a concentrated manner by the spiral feed rod 73, preventing the blocking material from accumulating inside and avoiding interference with subsequent switching or reuse.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.

The extension plate (63) is fixedly connected to the adjustment frame (61); A tension spring (64) is elastically connected between the extension plate (63) and the bearing plate (51); Two stop posts (65) are symmetrically arranged on the bearing plate (51) with the adjusting frame (61) as the center, and are used to limit the deflection angle of the adjusting frame (61); The abutment plate (66) is fixedly installed on the inner top of the sliding frame (41); When the drive device (5) drives the bearing plate (51) to rise and fall, the adjustment frame (61) cooperates with the triangular baffle (6) and the abutment plate (66) to drive the sliding frame (41) to slide automatically horizontally, thereby realizing the automatic switching of the conveying channel (24) of the arc-shaped pipe (22).

6. A pneumatic pipeline conveyor for metering and dispensing cell wall broken Phellinus linteus powder according to claim 5, characterized in that: Also includes: The collection trough (7) is located below the center of the conveying arc frame (21); A slot (71) is opened in the middle area of ​​the conveying arc frame (21) and is connected to the collection trough (7); The material discharge port (72) is located on the arc-shaped pipe (22) at the bottom of each conveying channel (24); The spiral feed rod (73) is set on the conveying pipe support (1) and connected to the collection tank (7) to force the blockage material falling into the collection tank (7) to the outside; When the conveying channel (24) is switched to the non-working position, the discharge port (72) at its bottom is aligned with the slot (71), so that residual or clogging powder falls into the collection tank (7).

7. A method of using a pneumatic pipeline conveyor for metering and dispensing cell wall-broken Phellinus linteus powder, comprising using the pneumatic pipeline conveyor for metering and dispensing cell wall-broken Phellinus linteus powder as described in any one of claims 1-6, characterized in that, Includes the following steps: S1: Start the Roots blower (12) to make the airflow flow horizontally along the horizontal pipe (11). The powder falls from the hopper (13) into the horizontal pipe (11), is carried by the airflow through the inlet (211) into the conveying channel (24) which is currently in the working position, and then enters the vertical pipe (14) through the outlet (212) to complete the powder conveying. S2: When it is necessary to switch the conveying channel (24), start the drive device (5) to drive the bearing plate (51) and the plug plate (53) to move in the vertical direction, so that the plug plate (53) separates from the guide side plate (42) on the side of the current working state. During the separation process, the wave-shaped continuous guide groove (54) and the sliding roller (422) make intermittent contact, causing the pressure shaking frame (34) to shake slightly along the axis of the fixed sleeve (31). The shaking is transmitted to the side wall of the arc pipe (22) through the sealing gasket (32), shaking off the attached powder. S3: The drive device (5) operates, and through the cooperation of the adjusting frame (61) and the triangular baffle (6), the sliding frame (41) drives the fixed sleeve (31) and the arc-shaped pipe (22) to slide in the conveying arc frame (21), and moves the other conveying channel (24) to the position aligned with the inlet (211) and outlet (212), thus completing the switching of the conveying channel (24); S4: During the sliding process of the arc-shaped pipe (22), the stationary frame steel bar (33) and the arc-shaped pipe (22) undergo relative displacement, scraping and breaking the arch in the original conveying channel (24), dispersing the blocked powder. At the same time, the drop port (72) at the bottom of the conveying channel (24) which has been switched to the non-working position aligns with the slot (71) on the conveying arc frame (21), causing the residual powder to fall into the collection tank (7) and be forcibly discharged by the spiral feed rod (73). S5: After the switch is completed, the plug plate (53) is re-inserted into the through groove (421) of the new working side guide plate (42), and the protruding part of the wave-shaped continuous guide groove (54) squeezes the sliding roller (422), so that the pressure shaking frame (34) maintains a constant pressure on the sealing gasket (32) and restores the sealed conveying state.
