AI Technical Summary
In the preparation of wet granules of Dendrobium officinale, due to its high viscosity caused by being rich in polysaccharides, traditional feeding methods are prone to causing the wet material to be squeezed and crushed when the valve is closed, as well as deviations in the amount of material fed, which affect the continuity and stability of the drying process.
The material is fed by forced rotation of spiral conveyor blades, combined with a diffusion cone and a vibrating drying tray. The rotation of the spiral blades and the dynamic dispersion of the diffusion cone ensure that the wet material is evenly layered and spread, avoiding adhesion and accumulation. The drying tray driven by a vibrating motor realizes high-frequency vibration and flexible adjustment of the regulating plate to ensure uniform material distribution.
It enables precise quantitative input of wet materials, avoids breakage and local accumulation, improves drying efficiency and uniformity, and ensures the continuity and stability of the drying process.

Description
Technical Field
[0001] This invention relates to the field of Dendrobium granule preparation, and more specifically, to an apparatus for preparing Dendrobium officinale compound granule formulations. Background Technology
[0002] Dendrobium officinale, with its dried stems used in traditional medicine, has the traditional effects of nourishing the stomach and promoting the production of body fluids, as well as nourishing yin and clearing heat. Modern pharmacological studies have shown that the active ingredients in Dendrobium officinale, such as polysaccharides, alkaloids, and amino acids, can promote gastric juice secretion, enhance gastrointestinal motility, and repair gastric mucosal damage. It also has a significant effect on improving symptoms of digestive system dysfunction such as spleen deficiency and abdominal distension, indigestion, and chronic gastritis. By combining Dendrobium officinale with other medicinal and edible wet materials such as yam, malt, and tangerine peel, and granulating them into granules, the active ingredients of each raw material are preserved. This formulation not only has the advantages of convenient administration, rapid absorption, and easy taste, but is also particularly suitable for daily conditioning and adjunctive treatment of people with impaired digestive function.
[0003] In the preparation process of Dendrobium officinale compound granules, after the Dendrobium officinale raw material obtained by treatment is mixed evenly with various excipients, it needs to be granulated into granules by wet granulation process. Among them, extrusion cutting granulation is a commonly used technical method. During the production process, a binder is first added to the wet material to knead it into a soft material. The powder is agglomerated by the bridging effect of the binder. Then the soft material is fed into the granulator. The wet material is forced to be extruded from the screen holes by rotating blades or screws to form cylindrical strips. Then the strips are cut into uniform granules of a certain length by external rotating cutting blades.
[0004] After granulation, the resulting wet Dendrobium officinale granules have a high moisture content, with a large amount of free water remaining on the surface and inside the granules. They need to be dried immediately to reach the specified moisture content standard. Currently, in industry, drying ovens are commonly used to dry the wet granules. During operation, the granules are placed on drying trays and pushed into the oven. When feeding the Dendrobium officinale granules into the drying trays from top to bottom, a quantitative feeding method is usually used, with a fixed amount of granules added to the drying tray each time. Therefore, traditional feeding mechanisms have valves at the discharge port to control the amount of Dendrobium officinale granules fed. However, because Dendrobium officinale granules are rich in polysaccharides and are in a wet state immediately after extrusion granulation, controlling the feeding amount by opening and closing the valve can cause the valve to cut off the Dendrobium officinale granules during the conveying process when it is closed. This results in some Dendrobium officinale granules being crushed, thus affecting the particle size and finished product quality of the dried Dendrobium officinale granules. Summary of the Invention
[0005] This invention provides a device for preparing compound granule formulations of Dendrobium officinale, which solves the technical problem in related technologies that the wet granules of Dendrobium officinale are rich in polysaccharides and have high viscosity, which causes the wet material at the bottom to be squeezed by gravity and adhere to the inner wall of the valve during the valve closure period when quantitative feeding is carried out, resulting in feeding deviation and wet material residue, and thus affecting the continuity and stability of the subsequent drying process.

[0015] In a preferred embodiment, the system further includes a transmission assembly comprising a locking block, a transmission block, a connecting rod, and a reset motor.

The bottom end of the connecting rod is fixedly connected inside the machine body. The top end of the connecting rod passes through the collar and is slidably connected inside the collar.
[0016] The beneficial effects of this invention are as follows: 1. This invention uses a spiral conveying blade to force the material to rotate, replacing the traditional valve-operated feeding method. This completely avoids the problem of compression and adhesion caused by the high viscosity of wet Dendrobium officinale granules due to their high polysaccharide content. The continuous rotation of the spiral blade pushes the material in layers, eliminating the adhesion to the pipe wall caused by the accumulation and compression of the material by its own weight. This ensures that the amount of material fed into the drying tray each time is accurate and controllable, effectively solving the problem of feeding deviation caused by material residue in the traditional feeding method, and ensuring the continuity and stability of the drying process. 2. This invention features a rotating diffusion cone at the discharge port, which dynamically disperses the concentrated falling bundles of material. Combined with the high-frequency vibration of the drying tray driven by a vibration motor, the wet particles are automatically spread into a uniform thin layer on the tray surface. This solves the problem in traditional feeding methods where the material is concentrated in the central area of the drying tray and cannot be diffused to the surrounding areas by vibration alone. It also avoids the uneven distribution of material layer in the central area and the absence of material in the edge area, thus greatly improving drying efficiency and drying uniformity.
[0017] 3. This invention uses the intermittent contact between the rotating block and the protrusion, combined with the energy storage and reset of the elastic element and the torsion spring, to make the first cone reciprocate torsion and swing. The dynamically changing throwing trajectory avoids excessive scattering caused by a single centrifugal force, and realizes adaptive adjustment of the adhesion fluctuation of different batches of materials, ensuring that the materials are always evenly dispersed in the effective area of the drying tray.
[0018] 4. This invention uses the collar in the second cone to move up and down along the screw, and the connecting arm drives the adjusting plate to swing, thereby precisely changing the vertical position of the diffusion cone and the material diffusion radius. When it is necessary to expand the coverage area, the angle between the adjusting plate and the screw is increased; when it is necessary to concentrate the material, the angle is decreased. This allows the equipment to be flexibly adjusted according to the size of the drying tray and the characteristics of the material, ensuring that the wet particles are evenly distributed on the entire surface of the drying tray and effectively avoiding the problem of local accumulation.
[0019] 5. This invention transmits the high-frequency vibration of the drying tray to the adjusting plate through the transmission component, so that the wet material adhering to the surface of the adjusting plate gradually falls off under the continuous micro-vibration, avoiding the accumulation of material after multiple feedings that affects the drying effect. At the same time, the separation between the clamping block and the mounting block ensures the cleanliness of the vibration transmission and prevents the vibration from being transmitted to the connecting shaft, thus preventing the wet material inside the feeding component from adhering to the inner wall of the conveying pipe due to vibration.

[0033] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.
[0034] like Figure 1 , Figure 2 and Figure 3 As shown, a device for preparing compound granules of Dendrobium officinale includes a body 1, inside which a vibration component 5 and a drying tray 6 are installed. The vibration component 5 is connected to the drying tray 6 and is used to drive the drying tray 6 to vibrate. A feeding component 2 is installed directly above the drying tray 6 and is fixedly connected to the top of the body 1. The feeding assembly 2 includes a feeding pipe 202, a central shaft 203, and a spiral feeding blade 204. A circular hole is provided on the top of the machine body 1. The top end of the feeding pipe 202 is fixedly connected to the inner wall of the circular hole. The central shaft 203 is driven to rotate inside the feeding pipe 202. The spiral feeding blade 204 is fixedly connected to the circumferential side of the central shaft 203. The outer side of the spiral feeding blade 204 forms an abutting connection with the inner wall of the feeding pipe 202.
[0035] It should be noted that a drying unit is also installed inside the machine body 1. The drying unit is used to dry the wet material (Dendrobium officinale granules) on the drying tray 6. The drying unit can be an electric heating structure such as a heating wire or heating tube, which is existing technology and will not be described in detail. A drive motor 7 is fixedly connected to the top of the machine body 1, and the bottom output end of the drive motor 7 is fixedly connected to the top of the central shaft 203. The vibration assembly 5 includes a vibration motor 501 and a leaf spring 502. An installation groove is opened on the inner wall of the machine body 1. The vibration motor 501 is fixedly connected inside the installation groove. The output end of the vibration motor 501 is connected to the drying tray 6. One end of the leaf spring 502 is fixedly connected to the drying tray 6, and the other end of the leaf spring 502 is fixedly connected to the inner wall of the machine body 1. The feeding assembly 2 also includes a feeding hopper 201, which is fixedly connected to the top of the machine body 1 and is connected to the central shaft 203.
[0036] It should be further explained that the machine body 1 provides mounting support for each functional component. The drying tray 6 forms a vibration drive structure through a vibration motor 501 fixedly connected to its side. This vibration drive structure is existing technology. The drying tray 6 is connected to the inner wall of the machine body 1 only through four leaf springs 502. The leaf springs 502 are long and thin, with a small moment of inertia in their cross section, easy to bend in the thickness direction, and can provide sufficient restoring force in the tensile direction. The material for making the leaf springs 502 can be spring steel or silicon manganese steel. The leaf springs 502 have high tensile strength and can withstand high-frequency alternating loads, ensuring that they will not break during long-term operation. Through the drive of the vibration motor 501 and the flexible support of the leaf springs 502, the drying tray 6 can generate high-frequency vibration when receiving wet material, so as to achieve uniform spreading of the wet material. The feeding hopper 201 is fixedly connected to the top of the machine body 1 and communicates with the central shaft 203 for feeding the material to be processed. The wet granules are fed through a conveying pipe 202, which is fixedly connected to the top of the machine body 1. The inside of the hopper 201 is connected to the inside of the conveying pipe 202, forming a downward channel for the wet granules. The drive motor 7 drives the central shaft 203 to rotate inside the conveying pipe 202, which in turn drives the spiral conveying blades 204 to rotate. The rotation forces the wet granules to be conveyed downward in a quantitative manner. The outer surface of the spiral conveying blades 204 abuts against the inner wall of the conveying pipe 202, so the wet granules on the surface of the spiral conveying blades 204 are layered by the spiral conveying blades 204. After the wet granules are layered, their weight is dispersed, and they will not be crushed due to their own weight. At the same time, the drive motor 7 controls the rotation of the central shaft 203 to start and stop, thereby controlling the amount of wet granules fed in. The wet granules can maintain their integrity inside the conveying pipe 202 and will not be crushed due to the opening and closing of traditional valves.
[0037] In this embodiment, the wet Dendrobium officinale granules obtained after extrusion granulation are fed into the hopper 201. Under gravity, the wet material enters the conveying pipe 202. The drive source drives the central shaft 203 to rotate, which in turn drives the spiral conveying blades 204 to rotate synchronously within the conveying pipe 202. Through the forced pushing action of the spiral blades, the wet granules accumulated in the conveying pipe 202 are continuously and quantitatively conveyed to the bottom, preventing blockage caused by the accumulation and compression of the wet material due to its own weight. When the wet material reaches the bottom of the conveying pipe 202, preliminary radial distribution is achieved. During operation, the drying unit heats the wet material on the drying tray 6. The vibration motor 501 drives the drying tray 6 to generate high-frequency micro-vibration, and the leaf spring 502 provides elastic support, so that the drying tray 6 receives the falling wet material under vibration. The wet particles falling into the drying tray 6 automatically flow and spread outwards under the action of vibration, forming a material layer of uniform thickness, avoiding local accumulation, thereby improving drying efficiency and drying uniformity. During the entire feeding process, the spiral conveyor blades 204 continuously rotate to force feeding, so even if the wet material has sticky characteristics, it will not stick to the pipe wall at the discharge port due to gravity compression.
[0038] like Figure 4 As shown in the above embodiment, when wet material is fed into the drying tray 6 from the feeding component 2, the material layer is evenly spread by the vibration of the drying tray 6. However, since the wet material falls in a concentrated bundle when it falls from the outlet of the feeding component 2, the wet material is concentrated in the central area of the drying tray 6. It is difficult to effectively diffuse the wet material piled in the center to the surrounding area by relying solely on the vibration of the drying tray 6. When the wet material piled up too thickly in the central area, the squeezing and adhesion between particles are enhanced, resulting in an excessively thick material layer in the central area and an excessively thin or even no material layer in the edge area, forming an uneven material layer distribution. Therefore, in order to solve this problem, in this embodiment, a diffusion cone 3 is connected to the bottom end of the central shaft 203, and the diffusion cone 3 is located directly above the drying tray 6.
[0039] It should be noted that the diffusion cone 3 is located above the drying tray 6 and directly below the spiral conveying blade 204, and at the bottom opening of the conveying pipe 202. It is used to evenly diffuse the wet material falling to the bottom in all directions, and achieve uniform material distribution in conjunction with the vibration of the drying tray 6.
[0040] In this embodiment, the feeding component 2 feeds wet material into the drying tray 6. The wet material falls onto the surface of the diffusion cone 3. The rotating diffusion cone 3 continuously and dynamically disperses the wet material, preventing it from accumulating at the outlet and ensuring that the feeding amount is accurate and continuous each time. Finally, the wet material is dispersed to various locations on the drying tray 6.
[0041] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown in the above embodiments, the adhesion of Dendrobium officinale wet granules prepared in different batches varies due to differences in moisture content, amount of binder added, and uniformity of mixing. Some Dendrobium officinale wet material may clump together from the time of extrusion, and the centrifugal force of unidirectional rotation is insufficient to effectively disperse the wet material, causing the wet material to fall in clumps. Therefore, to solve this problem, in this embodiment, the diffusion cone 3 includes a first cone portion 31 and a second cone portion 32, which are rotatably connected. The first cone portion 31 includes a cone block 311, a connecting shaft 315, a sleeve 316, an elastic element 317, and a slider 318. The top end of the connecting shaft 315 is fixedly connected to the bottom of the central shaft 203, and the circumferential side of the connecting shaft 315 is fixedly connected to one end of the sleeve 316. A groove is provided inside the sleeve 316, and the elastic element 317 is installed inside the groove. One end of the slider 318 extends into the sleeve 316 and forms a sliding guide engagement with the groove. One end of the elastic element 317 is fixedly connected to the end of the slider 318 that extends into the groove, and the other end of the elastic element 317 is fixedly connected to the inside of the sleeve 316. The conical block 311 has a through hole inside, the connecting shaft 315 is located inside the through hole, and the inner wall of the through hole has a mounting groove. The end of the slider 318 that is away from the sleeve 316 extends into the mounting groove and is slidably connected to the mounting groove. The second cone 32 is fixedly connected to the lower end of the connecting shaft 315. The first cone 31 also includes a mounting ring 312 and a protrusion. 313 and torsion spring 314, the outer side extension of mounting ring 312 is fixedly connected to the inner wall of conveying pipe 202, the bottom of mounting ring 312 is connected to the top of torsion spring 314, and the bottom end of torsion spring 314 is fixedly connected to the top of conical block 311; the inner wall of mounting ring 312 has a number of protrusions 313 arranged in a ring, and a rotating block 319 is fixedly connected to the top of slider 318. The rotating block 319 extends into the interior of mounting ring 312, and the rotating block 319 and the protrusions 313 form a limiting contact connection.
[0042] It should be further explained that the top end of the connecting shaft 315 is fixedly connected to the bottom of the central shaft 203, so that the connecting shaft 315 rotates synchronously with the central shaft 203, and the sleeve 316 rotates with the central shaft 203; the internal groove of the sleeve 316 is opened along its axial direction, that is, the slider 318 can slide telescopically within the sleeve 316, and the elastic element 317 provides a continuous outward pushing force. In this embodiment, the elastic element 317 can be a spring, elastic sheet or other elastic telescopic structure. The conical block 311 has a through hole inside, and the diameter of the connecting shaft 315 is smaller than the diameter of the through hole, that is, the connecting shaft 315 can rotate within the through hole; at the same time, the end of the slider 318 facing away from the elastic element 317 is slidably connected to the mounting groove. Inside, the rotational motion of the sleeve 316 is transmitted to the conical block 311 through the slider 318, while allowing the conical block 311 to have axial or circumferential displacement relative to the slider 318 when subjected to force; the mounting ring 312 is fixedly supported inside the feed pipe 202, keeping it stationary and not rotating; the conical block 311 is suspended below the mounting ring 312 by the torsion spring 314, which provides a circumferential restoring torque for the conical block 311; the rotating block 319 extends upward into the interior of the mounting ring 312, forming a sliding connection with the inner wall of the mounting ring 312; and during the revolution of the rotating block 319 with the central axis 203, it will intermittently abut against the protrusion 313 on the inner wall of the mounting ring 312. It is important to note that, such as Figure 8 As shown, multiple levers are arranged on the conical inclined surface of the conical block 311, which are used to touch the wet material through the swing of the levers when the conical block 311 swings back and forth, so that the clump of wet material is initially dispersed.
[0043] In this embodiment, when wet material falls from the bottom of the feed pipe 202 onto the diffusion cone 3, the wet material first lands on the surface of the cone block 311. The central shaft 203 is driven to rotate continuously, causing the connecting shaft 315 fixedly connected to its bottom and the sleeve 316 fixedly connected to its circumferential side to rotate synchronously. The slider 318 connected inside the sleeve 316 by the elastic element 317 rotates together with the sleeve 316. The end of the slider 318 is slidably connected to the mounting groove in the inner wall of the through hole of the diffusion cone 3. At the same time, the rotating block 319 at the top of the slider 318 extends into the fixed mounting ring 312. As the central shaft 203 rotates, the rotating block 319 moves in the mounting groove. The inner wall of ring 312 slides in a circular motion, while the conical block 311 rotates with the central axis 203. At this time, the torsion spring 314 at the top of the conical block 311 is rotated under force. When the rotating block 319 meets the protrusions 313 arranged in a ring array on the inner wall of the mounting ring 312, the two form an abutting connection. The protrusions 313 provide instantaneous blocking force to the rotating block 319. This blocking force forces the slider 318 to overcome the elastic force of the elastic element 317 and retract into the sleeve 316. At this time, one end of the slider 318 leaves the mounting groove, and the conical block 311 is no longer subjected to continuous rotational force. The elastic potential energy accumulated by the torsion spring 314 is released, driving the conical block 311 to rotate. Block 311 resets in the opposite direction of rotation. When rotating block 319 passes over protrusion 313 under the retraction of slider 318, the blocking effect of protrusion 313 disappears, and elastic element 317 releases its elastic force instantaneously, pushing slider 318 and rotating block 319 to reset outward. Since the central shaft 203 rotates continuously, slider 318 continues to rotate until it is inserted into another mounting slot. Each time rotating block 319 passes a protrusion 313, conical block 311 completes one reciprocating oscillation cycle. During the falling of wet material, the wet Dendrobium officinale particles conveyed by conveying pipe 202 fall onto the surface of diffusion cone 3. Due to the conical block 319... 11 is in a continuous intermittent reciprocating rotation state. The contact angle and throwing direction between the grooves on its conical surface and the wet material are constantly changing dynamically. Regardless of whether the viscosity of the wet material is high or low, the reciprocating swing of the conical block 311 causes the wet material in clumps or clusters to be initially dispersed. The initially dispersed wet material falls onto the surface of the continuously rotating second cone 32. Through the centrifugal force generated by the continuous rotation of the second cone 32, the wet material is thrown from the second cone 32 onto the surface of the drying tray 6. This process avoids excessive dispersion caused by a single centrifugal force direction. Finally, the wet material falls into the drying tray 6 below in a uniformly dispersed state, avoiding the wet material from always being dispersed in one direction.
[0044] like Figure 5 , Figure 6 and Figure 7As shown in the above embodiment, since the height positions of the feeding assembly 2 and the second cone 32 are relatively fixed, and the surface area of the drying tray 6 is large, the second cone 32 cannot evenly distribute all the wet material onto the surface of the drying tray 6, resulting in the problem of wet material accumulation during continuous feeding. Therefore, to solve this problem, in this embodiment, the second cone 32 includes a mounting block 321, an adjusting plate 322, a connecting arm 323, a collar 324, and a lead screw 325. The mounting block 321 and... The bottom of the connecting shaft 315 is connected, the outer side of the mounting block 321 is hinged to one end of the adjusting plate 322, the bottom of the adjusting plate 322 is hinged to one end of the connecting arm 323, the other end of the connecting arm 323 is hinged to the outer side of the collar 324, the collar 324 is located directly below the mounting block 321, and the collar 324 is threadedly connected to the lead screw 325; a hole is opened at the center of the drying tray 6, the bottom end of the lead screw 325 passes through the hole and is fixedly connected to the inside of the machine body 1, and the collar 324 slides along the vertical setting direction of the lead screw 325.
[0045] It should be further explained that the mounting block 321 is fixedly connected to the bottom of the connecting shaft 315, serving as the top mounting base of the second cone 32. The adjusting plate 322 can swing relative to the mounting block 321. The bottom of the adjusting plate 322 is hinged to one end of the connecting arm 323, and the other end of the connecting arm 323 is hinged to the outer side of the collar 324. Thus, a connecting rod 403 transmission mechanism is formed between the mounting block 321 and the collar 324. The lead screw 325 passes through the collar 324 and engages with the internal thread. That is, the collar 324 can slide up and down along the vertical direction of the lead screw 325 through the thread drive. The bottom end of the lead screw 325 passes through the hole and is fixedly connected to the inside of the machine body 1, keeping the lead screw 325 in a vertical fixed state. The collar 324 slides on the lead screw 325 in the vertical direction. The vertical position of the collar 324 on the lead screw 325 can be changed through the thread drive. When the collar 324 rises and falls, the adjusting plate 322 swings through the connecting arm 323.
[0046] In this embodiment, initially, the adjusting plate 322 and the drying tray 6 are parallel. As the wet material is continuously and evenly dispersed onto the surface of the adjusting plate 322 through the first cone 31, the adjusting plate 322 continuously rotates in one direction under the drive of the rotating connecting shaft 315, evenly dispersing the material into the interior of the drying tray 6. When the rotating connecting shaft 315 drives the adjusting plate 322 and the connecting arm 323 to rotate, the rotation acts on the collar 324, causing the collar 324 to move vertically up and down along the thread of the screw 325. When the collar 324 moves downward, the connecting arm 323 pulls down the bottom of the adjusting plate 322, causing the adjusting plate 322 to swing inward. The larger the angle between the adjusting plate 322 and the screw 325, the larger the material diffusion radius, covering a wider area of the drying tray 6. The smaller the angle between the adjusting plate 322 and the screw 325, the shorter the material falling distance and the more concentrated the landing point, ensuring that the wet particles are evenly distributed on the entire surface of the drying tray 6, effectively avoiding local accumulation problems.
[0047] like Figure 11 and Figure 12 As shown in the above embodiment, after a certain amount of wet material is fed into the drying tray 6 through the feeding component 2, due to the adhesive properties of the wet material, it may stick to the surface of the adjusting plate 322. After multiple feedings, the amount of wet material sticking to the surface of the adjusting plate 322 may increase, eventually affecting the drying of the wet material. Therefore, to solve this problem, this embodiment also includes a transmission component 4. The transmission component 4 includes a locking block 401, a transmission block 402, a connecting rod 403, and a reset motor 404. One end of the locking block 401 is fixedly connected to the bottom end of the connecting shaft 315. The top of the mounting block 321 has a slot, and the extension of the bottom of the mounting block 401 forms a contact connection with the inside of the slot. The top of the collar 324 is fixedly connected to the bottom of the transmission block 402. The transmission block 402 slides along the axial direction of the lead screw 325, and the transmission block 402 and the top protrusion of the drying tray 6 form a limiting contact fit. The bottom of the lead screw 325 is fixedly connected to the output end of the reset motor 404. The reset motor 404 is fixedly connected inside the machine body 1. The bottom of the connecting rod 403 is fixedly connected inside the machine body 1. The top of the connecting rod 403 passes through the collar 324 and is slidably connected inside the collar 324.
[0048] It should be further explained that the connecting shaft 315 and the mounting block 321 are connected by the locking block 401. The connecting shaft 315 rotates continuously, causing the collar 324 to slide downwards. When the adjusting plate 322 has been adjusted to its limit angle, that is, the angle between the adjusting plate 322 and the lead screw 325 is adjusted to the minimum angle, the adjusting plate 322 can no longer swing. At this time, the connecting shaft 315 is still rotating, and the locking block 401 at the bottom of the connecting shaft 315 gradually slides away from the groove inside the mounting block 321. That is, the locking block 401 slides away from the groove in the vertical direction until the locking block 401 separates from the mounting block 321. The transmission block 402 is sleeved on the lead screw 325 and forms a sliding connection in the vertical direction of the lead screw 325. That is, the transmission block 402 rises and falls synchronously with the collar 324 and maintains vertical movement under the guidance of the lead screw 325. When the drying tray 6 generates high-frequency vibration under the drive of the vibration motor 501, its top protrusion 313 periodically hits the transmission block 402, causing the drying tray to rotate. Vibrational energy is transmitted to the collar 324 through the transmission block 402, and then to the mounting block 321 and the surface of the adjusting plate 322 through the connecting arm 323, adjusting plate 322 and other connecting rods 403 mechanism. This causes the wet material adhering to the adjusting plate 322 to gradually fall off under the continuous micro-vibration and fall into the drying tray 6 below to participate in drying, thereby avoiding the long-term accumulation of material on the surface of the adjusting plate 322. When reset is required, the reset motor 404 is started to drive the lead screw 325 to rotate. Under the limiting action of the connecting rod 403, the collar 324 is driven to rise by the rotation of the lead screw 325 until the included angle between the adjusting plate 322 and the lead screw 325 is adjusted to the maximum, that is, the adjusting plate 322 and the drying tray 6 are in a parallel state. At this time, the adjusting plate 322 can no longer be adjusted upward. At this time, the collar 324 is still driven to move upward by the rotation of the lead screw 325. Therefore, the entire second cone 32 moves upward until the locking block 401 is inserted into the locking groove inside the mounting block 321.
[0049] In this embodiment, the drying tray 6 continuously generates high-frequency vibration under the drive of the vibration motor 501. When the collar 324 descends to the bottom of the lead screw 325 through the thread drive, the bottom end of the transmission block 402 contacts the top protrusion of the drying tray 6. When the drying tray 6 vibrates, its top protrusion forms an intermittent abutting connection with the bottom end or side of the transmission block 402. That is, the protrusion impacts the transmission block 402 once every time it vibrates. This impact force is transmitted to the collar 324 through the transmission block 402, causing the collar 324 to generate a weak instantaneous vibration on the lead screw 325. The vibration of the collar 324 is transmitted to the bottom of the adjusting plate 322 through the connecting arm 323, thereby causing the wet material adhering to the surface of the adjusting plate 322 to be vibrated off the adjusting plate 322, ultimately achieving the function of cleaning the adjusting plate 322. Meanwhile, since the mounting block 321 is connected to the bottom end of the connecting shaft 315 through the locking block 401, when the locking block 401 is separated from the mounting block 321, that is, when the second cone 32 is separated from the connecting shaft 315, the vibration of the second cone 32 cannot be transmitted to the feeding assembly 2 through the connecting shaft 315, thereby ensuring that the wet material inside the feeding assembly 2 is prevented from sticking to the inner wall of the conveying pipe 202 due to vibration; In summary, in this embodiment, when the collar 324 moves from the lead screw 325 to the bottom, the transmission block 402 contacts the top protrusion of the drying tray 6. At this time, the continuously vibrating drying tray 6 transmits the vibration to the surface of the transmission block 402. Through the vibration transmission, the second cone 32 vibrates as a whole, shaking the residual wet material adhering to the surface of the second cone 32 into the interior of the drying tray 6. At the same time, since the second cone 32 is disconnected from the connecting shaft 315, the vibration of the second cone 32 cannot be transmitted to the feeding assembly 2, so the vibration cannot affect the feeding assembly 2.
