Description

Technical Field

[0001] This invention relates to the field of health product manufacturing technology, specifically a fully automatic high-speed counting machine. Background Technology

[0002] In the upstream and downstream petroleum industry chain, petroleum derivatives (such as glycerol and fatty acids) are widely used as key raw materials in the manufacture of excipients and carriers for health products, driving the large-scale development of the health product industry. In the repackaging and packaging of health products, high-speed counting is required to achieve efficient and accurate counting of particulate materials (such as capsules and tablets), thereby improving production line efficiency and ensuring product consistency.

[0003] However, current high-speed grain counting machines still have the following problems during operation: 1. Granular materials (especially health product granules containing oily excipients such as glycerin and fatty acids) are prone to stickiness and dust adsorption due to their high surface viscosity. They are also easily affected by static electricity during transportation, which can cause them to stick together or agglomerate. Such sticking not only leads to poor material flow and blockage of channels, but also makes it difficult to separate individual particles, which seriously affects the subsequent counting accuracy and often causes a significant increase in counting error, making it difficult to meet the process requirements of high-speed and high-accuracy particle counting operations.

[0004] 2. Existing equipment mostly uses rigid guide channels or vibratory feeders. During high-speed conveying, particulate materials are prone to accumulation and blockage due to narrow channels, abrupt structural changes, or forced guidance. At the same time, the intense friction or impact between the hard contact surface and the particles can easily cause wear, deformation, or even cracking of the soft, oily particles. This not only affects the appearance and integrity of the product but may also cause cross-contamination or inaccurate dosage, making it difficult to achieve both high efficiency and high yield. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a fully automatic high-speed grain counting machine, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic high-speed particle counting machine, comprising: a feeding system and a material handling device; a dispersing pipe, wherein the dispersing pipe is disposed between the feeding system and the material handling device, and multiple sets are arranged in parallel along the direction perpendicular to the material conveying direction; the dispersing pipe is a flexible tubular structure capable of independently performing axial reciprocating extension and contraction, rotation around its own axis, and local radial deformation, so that the granular material passing through it is disturbed within the dynamic deformation channel; a striking plate, wherein the striking plate is disposed on the outside of the dispersing pipe, and applies multi-directional periodic impact force to its outer wall during the extension and contraction and rotation of the dispersing pipe, thereby causing the adhered granular material to separate from each other and peeling off the powder impurities attached to the surface of the particles; and a negative pressure air duct, wherein the negative pressure air duct is disposed on the inner wall of the dispersing pipe, and is used to continuously suck up the dust raised by the striking action during the passage of granular material.

[0007] Furthermore, the middle part of the dispersing pipe is a U-shaped flexible pipe, and its curved section extends along the material conveying direction, so that the particulate material rolls during the passage due to the synergistic effect of gravity and dynamic deformation of the pipe wall, thereby enhancing the deagglomeration effect of the adhering particles.

[0008] Furthermore, the middle part of the dispersion pipe is a spiral flexible pipe with its spiral axis extending along the material conveying direction, so that the particulate material is subjected to continuous centrifugal disturbance and radial compression during the passage, thereby improving the stripping efficiency of surface powder impurities.

[0009] Furthermore, the inner wall of the dispersion pipe is rotatably fitted with a plurality of ball bearings arranged in a spiral pattern.

[0010] Furthermore, the negative pressure duct includes two sets of spiral suction grooves formed on the inner wall of the dispersion pipe. The two sets of spiral suction grooves rotate in opposite directions, which are used to simultaneously suck up dust raised from different circumferential directions when particulate material passes through.

[0011] Furthermore, a conical sleeve is fixedly installed on the inner wall of the discharge end of the dispersion pipe. Multiple circumferentially evenly distributed inclined brushes are ball-jointed on the inner circumferential surface of the conical sleeve, and the bristles of the inclined brushes are inclined toward the central axis of the dispersion pipe.

[0012] Furthermore, a fixed plate is provided on the outer side of the dispersing pipe, and multiple spring telescopic rods are installed on the outer side of the fixed plate. The spring telescopic rods are arranged circumferentially along an elliptical trajectory centered on the axis of the dispersing pipe. A horizontal plate is installed at the telescopic end of the spring telescopic rods. A swing plate symmetrically distributed about the dispersing pipe is provided on the horizontal plate. The swing plate is hinged to the horizontal plate. An inclined groove plate is rotatably installed on the horizontal plate through a shaft equipped with a torsion spring. The end of the swing plate near the inclined groove plate is slidably engaged with the inclined groove plate through a pin. A pressure plate is installed at the end of the inclined groove plate near the center of the horizontal plate. A bracket is installed at the end of the swing plate away from the horizontal plate. A striking plate is hinged to the bracket.

[0013] Furthermore, connecting pulleys are fixedly fitted at both ends of the horizontal section of the dispersion pipe, and a fixed shaft is provided below the middle dispersion pipe. Drive pulleys are respectively fitted on the outside of the fixed shaft at positions corresponding to the connecting pulleys. The connecting pulleys and drive pulleys are connected by belt drive, and the connecting pulleys and drive pulleys rotate together on the same fixed frame. Two sets of spiral grooves are opened on the outer circumferential surface of the fixed shaft. The two sets of spiral grooves are respectively located at corresponding positions of the two drive pulleys and rotate in opposite directions. The inner wall of the drive pulley is equipped with a mating post that slides in connection with the spiral groove.

[0014] Furthermore, a push frame is provided on the opposite side of the drive pulleys on the left and right sides. The push frame is rotatably connected to the corresponding drive pulley. A symmetrical cam is provided between the left and right push frames. The symmetrical cam has a sliding groove that slides with the push frame. The lower end of the symmetrical cam is connected to the output shaft of the drive motor.

[0015] Furthermore, upright plates are installed between the two connecting pulleys on the same distributed pipeline on their adjacent sides, and an arc-shaped frame is provided between the upright plates. The ends of the arc-shaped frame are slidably connected to the upright plates through support plates. The inner side of the arc-shaped frame is provided with circumferentially evenly distributed arc-shaped plates, and the arc-shaped plates are slidably connected to the arc-shaped frame through spring columns.

[0016] The present invention has the following beneficial effects: (1) This fully automatic high-speed particle counting machine, by setting up a dispersion pipe that can independently realize axial reciprocating extension, rotation around its own axis and local radial deformation, applies a gentle and continuous multi-dimensional disturbance to the passing material by means of its dynamic deformation without damaging the granular material, effectively breaking the adhesion and agglomeration between particles, realizing the efficient separation of adhered individuals, and avoiding the blockage or damage problems caused by squeezing or scraping of traditional rigid structures, thus providing a stable, uniform and dispersed material flow for subsequent material handling and high-precision counting.

[0017] (2) This fully automatic high-speed particle counting machine, through the synergistic action of the beating plate and the arc plate, transforms the dynamic deformation of the dispersed pipe itself into an adaptive mechanical beating force in real time. Each spring telescopic rod is distributed circumferentially along an elliptical trajectory centered on the pipe axis, so that the beating units in different directions can respond independently when the pipe is deformed locally. Multiple beating plates act synchronously but non-uniformly on different areas of the pipe wall, forming a multi-angle, multi-point synergistic beating, which can not only apply a gentle and effective disturbance to the adhering particles, promote the disintegration of agglomerates and the shedding of surface dust, but also avoid rigid impact because the beating force is adaptively adjusted with the pipe deformation, effectively protecting the soft particles of oily auxiliary materials from damage.

[0018] (3) This fully automatic high-speed particle counting machine uses two sets of spiral suction grooves with opposite rotation directions as negative pressure air ducts. When the particle material passes through, it can simultaneously capture the dust raised by the slapping action from different circumferential directions. The tangential airflow generated by the spiral suction grooves not only enhances the dust removal effect on the particle surface, but also guides the dust to flow into the suction channel along the spiral path, significantly improving the uniformity and overall efficiency of dust removal, and effectively preventing secondary dust adhesion or accumulation in the pipeline.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] 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.

[0023] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0024] The following is based on Figures 1-10 This invention describes a fully automatic high-speed grain counting machine provided in an embodiment of the invention.

[0025] Example 1, please refer to this example. Figures 1-9 .

[0026] Please refer to Figure 1This fully automatic high-speed pellet counting machine includes a feeding system 1, a sorting device 2, a counting and detection system, and an execution and packaging mechanism (only part of the structure is shown in the figure) connected sequentially and set on the same base 4. It is used to complete the continuous conveying, orderly arrangement, accurate counting, and automatic packaging of granular materials. Among them, the feeding system 1 smoothly outputs the pellets from the hopper through vibration or spiral; the sorting device 2 uses multi-channel guide channels to guide and isolate the pellets, so that they are arranged in a single row with equal spacing, providing a stable input for subsequent counting; the counting and detection system uses a photoelectric sensor array or a high-speed vision module to identify and count the number of passing pellets in real time; when the count value reaches the preset target, the execution and packaging mechanism accurately introduces the pellets into the designated packaging container, ensuring packaging consistency and production efficiency.

[0027] Please refer to Figure 1 and Figure 2 Because particulate materials are prone to sticking together due to their own physical properties (such as oily auxiliary materials on the surface or static electricity), resulting in poor conveying and increased counting errors, they need to be effectively de-agglomerated and cleaned before entering the material handling device 2. For this purpose, a dispersion pipe 3 is set between the feeding system 1 and the material handling device 2. The particulate materials can enter the device by vibration. Multiple sets of dispersion pipes 3 are arranged in parallel along the direction perpendicular to the material conveying. Each dispersion pipe 3 corresponds to a channel guide groove in the material handling device 2. One end of the dispersion pipe 3 is rotatably connected to the outlet of the feeding system 1, and the other end is rotatably installed on the support ring 31 which is fixedly connected to the channel guide groove, so as to ensure both freedom of movement and structural stability.

[0028] The dispersion pipe 3 is made of elastic material and can independently achieve axial reciprocating expansion and contraction, rotation around its own axis, and local radial deformation. Without damaging the particles, it applies a gentle and continuous disturbance to the passing material through dynamic deformation, effectively breaking the particle agglomeration and separating the adhered individuals. At the same time, it avoids blockage caused by rigid compression, thus providing a stable, uniform, and dispersed material flow for subsequent material handling and high-precision counting.

[0029] Specifically, please refer to Figure 2 , Figure 3 and Figure 5The middle part of the dispersion pipe 3 is a U-shaped flexible pipe 32, whose curved section extends along the material conveying direction. Sufficient space is reserved between adjacent dispersion pipes 3 to ensure that they do not interfere with each other during movement. During the axial reciprocating expansion and contraction and rotation of the dispersion pipe 3, the U-shaped flexible pipe 32 deforms and generates periodic disturbances. When the particulate material passes through this area, it undergoes a rolling motion due to the combined effect of gravity and the flexible deformation of the pipe wall, which effectively weakens and breaks the adhesion between particles and significantly improves the deagglomeration effect on agglomerates. At the same time, when the U-shaped flexible pipe 32 tends to be horizontal during movement, the particles can slide out quickly and smoothly enter the downstream material handling device 2, thereby providing a more uniform, dispersed and stable material state for subsequent material handling and high-precision counting.

[0030] Please refer to Figure 8 Multiple spirally distributed ball bearings 321, made of flexible material, are rotatably installed on the inner wall of the dispersion pipe 3. During the passage of particulate material, the ball bearings 321 rotate with the rolling of the material. On the one hand, this significantly reduces the sliding friction between the particles and the pipe wall, preventing soft particles from being damaged by scratching. On the other hand, their spiral arrangement provides circumferential guidance to the particles, prompting the material to move along the spiral path and enhancing the disturbance effect. At the same time, when the dispersion pipe 3 undergoes radial deformation, the ball bearings 321 can apply localized and gentle squeezing and shearing action to the adhered particles, assisting in further separation of the particles and improving the deagglomeration efficiency.

[0031] Please refer to Figure 5 and Figure 6 To further improve the dust removal and deagglomeration efficiency of particulate materials, a fixing plate 322 is provided on the outside of the U-shaped flexible tube 32. Multiple spring telescopic rods 323 are installed on the outside of the fixing plate 322. The spring telescopic rods 323 are arranged circumferentially along an elliptical trajectory centered on the axis of the dispersing pipe 3. The initial compression of each spring telescopic rod 323 is set according to its position on the elliptical trajectory, so that its free end forms a non-circular symmetrical support profile in the reset state. During the expansion, contraction, rotation and radial deformation of the dispersing pipe 3, its outer wall comes into dynamic contact with and interacts with the spring telescopic rods 323. On the one hand, the spring telescopic rods 323 expand and contract accordingly, applying a periodic and directional external force to the U-shaped flexible tube 32 section, causing this section of the U-shaped flexible tube 32 to deform locally into an elliptical shape, which is conducive to the rolling and loosening of internal particles and smooth discharge. On the other hand, the external force is transmitted to the particles inside the tube, enhancing their movement activity, promoting the separation of adhering particles and the shedding of attached dust, thereby synergistically improving the deagglomeration and cleaning effect.

[0032] Please refer to Figure 6 and Figure 7A horizontal plate 324 is installed at the telescopic end of the spring telescopic rod 323. A swing plate 325 is symmetrically distributed about the dispersing pipe 3 on the horizontal plate 324. The swing plate 325 is hinged to the horizontal plate 324, and the hinge point is located below the center of gravity of the swing plate 325, so that the swing plate 325 tilts towards the dispersing pipe 3 in its natural state. An inclined groove plate 326 is rotatably installed on the horizontal plate 324 through a shaft fitted with a torsion spring. The end of the swing plate 325 near the inclined groove plate 326 is slidably engaged with the inclined groove plate 326 through a pin. A pressure plate 327 is installed at the end of the inclined groove plate 326 near the center of the horizontal plate 324. A bracket is installed at the end of the swing plate 325 away from the horizontal plate 324. A striking plate 329 is hinged to the bracket, and the hinge point is located above the center of gravity of the striking plate 329, so that the striking plate 329 maintains a vertical posture under the action of gravity.

[0033] When the dispersing pipe 3 compresses the spring telescopic rod 323 during its movement, it first compresses the pressure plate 327, pushing the inclined groove plate 326 to rotate around the hinge point between it and the horizontal plate 324. The rotation of the inclined groove plate 326 drives the swing plate 325 to swing around the hinge point between it and the horizontal plate 324 through the pin. The horizontal plate 324 has a clearance groove to ensure that the movement of the inclined groove plate 326 and the swing plate 325 does not interfere. When the swing plate 325 swings, it drives the support and the striking plate 329 to move synchronously towards the outer wall of the dispersing pipe 3, so that the striking plate 329 applies a directional impact to it.

[0034] Because the structure is symmetrically arranged about the dispersing pipe 3, the two side striking plates 329 can move synchronously towards each other, converting the dynamic deformation of the dispersing pipe 3 itself into an adaptive mechanical striking force. At the same time, each spring telescopic rod 323 is distributed along an elliptical trajectory, corresponding to the striking in different directions. It can respond independently when the dispersing pipe 3 deforms locally, so that multiple striking plates 329 act synchronously but non-uniformly on different areas of the outer wall of the dispersing pipe 3, forming a multi-angle, multi-point coordinated striking. This can not only apply a gentle and effective disturbance to the adhering particles, promoting the disintegration of agglomerates and the shedding of surface dust, but also avoid rigid impact because the striking force is adaptively adjusted with the deformation of the pipe, effectively protecting the soft particles of oily excipients from damage.

[0035] Please refer to Figures 2-5To achieve axial reciprocating extension and rotation of the dispersion pipe 3, connecting pulleys 331 are fixedly fitted at both ends of the horizontal section of the dispersion pipe 3. A fixed shaft 332 is provided below the middle of the dispersion pipe 3. The fixed shaft 332 is fixedly installed on the base 4. Drive pulleys 333 are respectively fitted on the outside of the fixed shaft 332 at the positions corresponding to the connecting pulleys 331. The connecting pulleys 331 and drive pulleys 333 are connected by a belt 334. The connecting pulleys 331 and drive pulleys 333 are rotatably mounted on the same fixed frame 335. The fixed frame 335 is slidably assembled on the base 4 through ribs to ensure the rigidity of the overall structure while allowing it to move smoothly along the axial direction of the fixed shaft 332. Two sets of spiral grooves 336 are opened on the outer circumferential surface of the fixed shaft 332. The two sets of spiral grooves 336 are located at the corresponding positions of the two drive pulleys 333 and rotate in opposite directions. The inner wall of the drive pulley 333 is equipped with a mating column 337 that is slidably connected to the spiral grooves 336.

[0036] In use, the two coaxially arranged drive pulleys 333 can move synchronously in opposite directions along the fixed shaft 332. Under the constraint of the fixed frame 335, their movement can be transmitted to the corresponding connecting pulleys 331, thereby driving the two ends of the dispersion pipe 3 to move synchronously. When the drive pulleys 333 move along the fixed shaft 332, the mating pins 337 on their inner walls slide into the corresponding spiral grooves 336 on the fixed shaft 332, converting the axial displacement into rotational motion, so that the drive pulleys 333 rotate synchronously during the movement. Since the two sets of spiral grooves 336 rotate in opposite directions, when the two drive pulleys 333 move towards or away from each other, the rotation direction they generate is the same, thereby driving the connecting pulleys 331 on both sides to rotate synchronously in the same direction through the belt 334. Thus, while the dispersion pipe 3 achieves overall rotation, both ends are subjected to reverse axial tension, completing the composite motion of synchronous extension and rotation.

[0037] Please refer to Figures 2-4 To achieve synchronous reverse movement of the two drive pulleys 333, push frames 338 are respectively provided on the opposite side of the drive pulleys 333 on the left and right sides. The push frames 338 are rotatably connected to the corresponding drive pulleys 333. A symmetrical cam 339 is provided between the left and right push frames 338. The symmetrical cam 339 is rotatably mounted on the base 4 and has a sliding groove that slides with the push frame 338. The track of the sliding groove extends along the contour of the symmetrical cam 339. The lower end of the symmetrical cam 339 is connected to the output shaft of the drive motor 340, which is mounted on the base 4.

[0038] During operation, the drive motor 340 drives the symmetrical cam 339 to rotate. The two protruding sections of the slide groove (i.e. the maximum radial offset area) alternately act on the push frame 338 on both sides, so that the two push frames 338 perform reciprocating linear motion in opposite directions or in opposite directions under the guidance of the slide groove, thereby driving the drive pulley 333 connected to it to move synchronously in the opposite direction along the fixed shaft 332.

[0039] Please refer to Figure 3 and Figure 5 A vertical plate 341 is installed between the two adjacent sides of the two connecting pulleys 331 on the same distributed pipe 3. An arc-shaped frame 342 is provided between the vertical plates 341. The end of the arc-shaped frame 342 is slidably connected to the vertical plate 341 through a support plate 343, so that the connecting pulleys 331 can move freely along the axial direction while rotating. A circumferentially evenly distributed arc-shaped plate 344 is provided on the inner side of the arc-shaped frame 342. The arc-shaped plate 344 is slidably connected to the arc-shaped frame 342 through a spring column 345.

[0040] During operation, when the connecting pulley 331 drives the dispersing pipe 3 to rotate, the vertical plate 341 rotates accordingly, and drives the arc frame 342 to rotate synchronously through the support plate 343. Since the support plate 343 and the vertical plate 341 are in sliding fit, the axial extension and retraction of the connecting pulley 331 is not interfered with. Under the elastic action of the spring column 345, the arc plate 344 always fits against the outer wall of the dispersing pipe 3. When the dispersing pipe 3 changes its shape due to extension, retraction or local deformation, the arc plate 344 generates an adaptive elastic displacement under the guidance of the spring column 345, applying a periodic and gentle radial force to the pipe wall, thereby disturbing the internal particulate material, promoting the separation of adhering particles, and improving the deagglomeration and dispersion effect.

[0041] Please refer to Figure 5 and Figure 6 To enable the fixed plate 322 and the spring telescopic rod 323, horizontal plate 324 and other structures installed on it to rotate synchronously with the dispersing pipe 3, a bidirectional telescopic rod 346 is provided on the fixed plate 322. The two telescopic ends of the bidirectional telescopic rod 346 are fixedly connected to the connecting pulleys 331 at the two ends of the dispersing pipe 3, respectively. When the connecting pulleys 331 rotate, the rotational motion is transmitted to the fixed plate 322 through the bidirectional telescopic rod 346, so that the whole plate rotates synchronously. At the same time, the bidirectional telescopic rod 346 allows for changes in axial length to adapt to the reciprocating expansion and contraction of the dispersing pipe 3 during operation.

[0042] Please refer to Figure 9A conical sleeve 347 is fixedly installed on the inner wall of the discharge end of the dispersing pipe 3. The small diameter end of the conical sleeve 347 faces the downstream material handling device 2. Multiple circumferentially evenly distributed inclined brushes 348 are spherically hinged on the inner circumferential surface of the conical sleeve 347. The bristles of the inclined brushes 348 are inclined towards the central axis of the dispersing pipe 3. When the granular material is discharged, it passes through the conical sleeve 347. Its gradually narrowing inner cavity plays a converging and guiding role on the material, so that the particles pass through one by one in an orderly manner. At the same time, the inclined brushes 348 elastically fit the particle surface under the adaptive adjustment of the spherical hinge, clean the residual dust, and further straighten the particle posture to ensure that the material flow entering the material handling device 2 is cleaner, more dispersed, and more stably arranged.

[0043] Furthermore, the elasticity and adjustable angle of the tilting brush 348 ensure that it only lightly touches the surface when the granular material passes through normally, without causing obstruction. Even when the dispersion pipe 3 is dynamically deformed or the granules are moving at high speed, the tilting brush 348 can follow the contour of the material to avoid jamming or sudden changes in resistance, thereby achieving effective cleaning without affecting the smooth conveying of granular materials.

[0044] Please refer to Figure 8 To continuously extract dust raised by the beating action during the passage of particulate material, a negative pressure air duct 349 is provided on the inner wall of the dispersion pipe 3. The negative pressure air duct 349 includes two sets of spiral suction grooves opened on the inner wall of the dispersion pipe 3. The two sets of spiral suction grooves rotate in opposite directions, which can simultaneously capture dust raised from different directions when the particles pass through. The tangential airflow generated by the spiral suction grooves not only accelerates the dust from the particle surface, but also guides it to quickly enter the suction channel along the spiral path, thereby improving the dust removal efficiency.

[0045] Please refer to Figures 1-3 and Figure 8 One end of the spiral suction trough near the feeding system 1 is connected to the annular air chamber 350 sleeved on the outside of the dispersion pipe 3. The annular air chamber 350 is fixed on the same mounting frame, which is fixedly installed on the base 4. The annular air chamber 350 is connected to the common negative pressure suction device 5 through the connecting pipe, so as to continuously suck and efficiently remove the dust raised by the beating action inside the dispersion pipe 3.

[0046] In actual operation (use), the granular material is fed into the dispersion pipe 3 by the feeding system 1 via vibration. After the drive motor 340 starts, it drives the symmetrical cam 339 to rotate. Through the push frame 338, the two drive pulleys 333 move synchronously towards or away from each other along the fixed shaft 332. Under the synergistic action of the mating column 337 and the spiral groove 336, the drive pulleys 333 rotate simultaneously. Through the belt 334, the connecting pulley 331 and the dispersion pipe 3 achieve a compound motion of axial reciprocating extension and retraction and rotation around the axis. During this process, the dynamic deformation of the dispersion pipe 3 squeezes the pressure plate 327. Through the inclined groove plate 326, the swing plate 325, the support and the horizontal plate 324, the dispersion pipe 3 achieves a compound motion of axial reciprocating extension and retraction and rotation around the axis. The linkage mechanism drives the tapping plate 329 to perform multi-directional adaptive tapping on the pipe wall. The spring telescopic rod 323 extends and retracts accordingly, while the arc plate 344 applies elastic radial force to the pipe under the action of the spring column 345. Together, they promote the deagglomeration of internal particles and the stripping of dust. At the same time, the negative pressure suction device 5 continuously sucks up the dust raised through the annular air chamber 350 and two sets of reverse spiral suction grooves to prevent secondary adhesion. The fully dispersed and cleaned particulate material then enters the conical sleeve 347 at the discharge end, where it is further cleaned and straightened by the inclined brush 348. Finally, it flows into the downstream material handling device 2 in a single, clean, and orderly state, laying the foundation for subsequent high-precision counting and packaging.

[0047] Example 2, please refer to this example. Figure 10 .

[0048] The difference between this embodiment and Embodiment 1 is that the middle part of the dispersion pipe 3 is a spiral flexible pipe 351, and its spiral axis extends along the material conveying direction. The three-dimensional spiral configuration causes the particulate material to be continuously subjected to the combined disturbance of centrifugal force and radial extrusion during the passage, which effectively enhances the relative movement between the particles and the pipe wall, thereby significantly improving the peeling efficiency of surface powder impurities.

[0049] In addition, related functional components such as ball bearings 321, striking plates 329, and arc plates 344 can be distributed circumferentially and axially along the spiral axis of the spiral flexible tube 351. Their installation positions are adapted to the spiral path to ensure that when the pipe expands, rotates, or undergoes local deformation, it can still apply an effective and uniform force to the pipe wall, thereby achieving full-process dynamic support and coordinated depolymerization of the spiral flexible tube 351.
