Description

Technical Field

[0001] The present application relates to the field of pellet machines, and in particular to a swing pellet machine. Background Art

[0002] The oscillating granulator is a device commonly used in the pharmaceutical field. It is mainly used to extrude wet-mixed drug powder into uniform drug granules of a specific particle size. Specifically, the oscillating granulator includes a granulation tank and an oscillating drum. The bottom of the granulation tank is provided with a screen whose mesh size matches the particle size of the drug granules. The oscillating drum is located inside the granulation tank and fits closely to the screen. During granulation, the drug powder needs to be poured into the granulation tank. Then, by reciprocating the oscillating drum, the wet-mixed drug powder between the screen and the oscillating drum is squeezed, so that the drug powder passes through the screen and forms drug granules of a specific particle size.

[0003] In existing technologies, to facilitate control of the rate at which drug powder enters the granulation tank, a powder storage hopper is typically installed at the top of the granulation tank. A discharge port is formed through the bottom of the hopper, and a slidable opening and closing plate engages with the discharge port. Drug powder is replenished in the powder storage hopper via the powder supply equipment box. The opening and closing plate is then pushed and pulled to adjust the size of the discharge port, thereby controlling the rate at which drug powder enters the granulation tank.

[0004] Regarding the above-mentioned related technologies, during actual application, the applicant found that when pushing and pulling the material port opening and closing plate, the wet mixed drug powder would adhere and accumulate on the material port opening and closing plate, causing part of the drug powder to fall onto the table of the granulator or directly fall to the ground, resulting in waste of drug powder. Summary of the Invention

[0005] In order to reduce the waste of medicine powder, the present application provides a swing-type granulator.

[0006] The present application provides a swing type pellet machine adopting the following technical solution: A swing type granulator, comprising a medicine powder storage hopper and a granulator body, wherein the granulator body is located at the bottom of the medicine powder storage hopper; The granulator body includes a granulation tank body and a swing drum, the granulation tank body is provided with a granulation chamber, the swing drum is located inside the granulation chamber, and the swing drum reciprocates in the granulation tank body; The medicine powder storage hopper is provided with a storage chamber and a medicine powder discharge port, wherein the storage chamber is used to store medicine powder, and the medicine powder discharge port is provided through the bottom of the medicine powder storage hopper and is communicated with the storage chamber; The medicine powder storage hopper is slidably matched with an opening and closing drawer, and the opening and closing drawer is used to open and close the medicine powder discharge port. A drawer chamber is opened on the top of the opening and closing drawer.

[0007] By adopting the above technical solution, when the medicine powder discharge port is opened and closed or its opening is adjusted, the residual scattered medicine powder will fall into the drawer chamber of the opening and closing drawer, and is not easy to fall from the surrounding areas of the opening and closing drawer, thereby reducing the occurrence of medicine powder falling onto the table or the ground, which is conducive to reducing the waste of medicine powder and improving the economic benefits of production.

[0008] Optionally, a powder guide plate is provided on the top of the granulation tank body, and the powder guide plate is inclined from top to bottom toward the storage chamber.

[0009] By adopting the above technical solution, the drug powder falling from the drug powder discharge port falls onto the drug powder guide plate, and then falls along the drug powder guide plate into the granulation chamber of the granulation trough body, thereby reducing the drug powder accumulated on the table, which is beneficial to reducing drug powder waste and improving the economic benefits of production.

[0010] Optionally, the top of the powder guide plate is smoothly arranged, and the bottom of the powder guide plate is rotatably matched with the granulation tank body.

[0011] By adopting the above technical solution, for drug powder that sticks to the powder guide plate due to high humidity, the drug powder can be shaken into the granulation chamber by reciprocating the powder guide plate, thereby reducing the waste of drug powder and the cleaning workload of production personnel, with low cost and good production feedback.

[0012] Optionally, the number of storage chambers provided in the medicine powder storage hopper is plural; The oscillating granulator also includes a powder conveying pipe, which is connected to a powder feeding device. The powder feeding device is used to convey drug powder. The powder conveying pipe is rotatably matched with a powder distribution pipe. The powder distribution pipe is located at the top of the storage chamber and is tilted from top to bottom.

[0013] By adopting the above technical solution, the powder distribution tube is helpful in reducing the height difference when the drug powder falls into the storage chamber, thereby making it difficult for the drug powder to scatter around the swing granulator described in the present invention due to gravity or pressure during transportation, thereby helping to reduce the waste of drug powder.

[0014] In addition, by rotating the medicine powder distributing pipe, the supply amount of medicine powder into two adjacent storage chambers can be intervened, which is low in cost and has good production feedback.

[0015] For example, when production demand is low and only a single powder storage hopper is needed for operation, the powder distribution tube is rotated to the top of the powder storage hopper so that the drug powder is concentratedly supplied to the powder storage hopper, reducing the use of other powder storage hoppers and reducing the workload of subsequent cleaning and maintenance.

[0016] For another example, when production demand is high and multiple powder storage hoppers are needed to work, the powder distribution tube is rotated between two adjacent powder storage hoppers, so that the drug distribution tube supplies the two adjacent powder storage hoppers at the same time, reducing the situation where the processing speed of a single powder storage hopper is too slow and does not match the production demand.

[0017] Optionally, the oscillating granulator further comprises a granule conveyor belt, wherein the granule conveyor belt is used to convey the drug granules; A particle screen is provided at the bottom of the pellet machine body, and the particle screen is located on the top of the particle conveyor belt. An air blowing cleaning member is installed on the pellet machine body, and the air blowing cleaning member is used to blow gas to the particle screen.

[0018] By adopting the above technical solution, gas is blown to the particle screen through the air blowing cleaning part, which will cause the drug powder adhering to the particle screen to be quickly blown away and fall onto the particle conveyor belt, reducing the waste of drug powder. Compared with other cleaning methods, it has high cleaning efficiency, does not require production suspension during the cleaning process, and is not easy to cause adverse effects on the shape of drug powder and drug particles, and has a good production effect.

[0019] Optionally, the pellet machine body is installed with an adjustment base plate, the adjustment base plate is provided with an air blowing chute, the shape of the air blowing chute is adapted to the bottom contour of the pellet screen, and the air blowing cleaning piece is slidably fitted in the air blowing chute.

[0020] By adopting the above technical solution, when the particle screen needs to be cleaned, air is supplied to the air blowing cleaning member through an air supply device such as an air pump, and the supplied air is blown out from the air blowing cleaning member. At this time, the staff pushes and pulls the air blowing cleaning member, causing it to slide within the air blowing chute, thereby ensuring that the air blowing cleaning member always blows along the contour of the particle screen, reducing the occurrence of fluctuating blowing distances, thereby ensuring that drug particles adhering to the particle screen are quickly blown off to the particle conveyor belt.

[0021] Optionally, the medicine powder storage hopper is equipped with a medicine powder scraper, the medicine powder scraper is located inside the drawer cavity, and the medicine powder scraper fits closely to the inner wall of the drawer cavity.

[0022] By adopting the above technical solution, on the one hand, when the opening of the powder discharge port is adjusted by opening and closing the drawer, the powder scraper will prevent the medicine powder from transferring from the rear end to the front end of the drawer chamber, thereby making it difficult for the medicine powder to be transferred again after entering the drawer chamber and fall onto the table or the ground, thereby helping to reduce the waste of medicine powder.

[0023] On the other hand, when too much medicine powder accumulates in the drawer chamber, the medicine powder will be pushed to one end of the drawer chamber by the powder scraper by pushing and pulling the drawer to open and close, making it convenient for production personnel to regularly clean and maintain the drawer.

[0024] Optionally, a powder cleaning port is provided through the opening and closing drawer, the powder cleaning port is located at the rear end of the powder storage hopper, and the powder cleaning port is connected to the drawer chamber; The opening and closing drawer is rotatably matched with a cleaning opening opening and closing plate, and the cleaning opening opening and closing plate is used to open and close the medicine powder cleaning opening.

[0025] By adopting the above technical solution, after the drug powder is pushed to one end of the drawer chamber by the powder scraper, the cleaning opening and closing plate is rotated to open the drug powder cleaning port, thereby facilitating the production personnel to complete the clean discharge of the drug powder without having to disassemble the opening and closing drawer.

[0026] Optionally, the rocking drum includes a rotating disk and a plurality of extrusion rods, the rotating disk is rotatably engaged with the powder storage hopper, the plurality of extrusion rods are circumferentially distributed around the axis of the rotating disk, and the plurality of extrusion rods are all slidably engaged with the rotating disk.

[0027] By adopting the above technical solution, when the wet-mixed drug powder adheres to the extrusion rod and the extrusion rod needs to be cleaned, the extrusion rod that needs to be cleaned is slid so that the extrusion rod is away from the other adjacent extrusion rod, thereby allowing the production personnel to have sufficient operating surface to clean the extrusion rod, thereby reducing the situation where the production personnel's hands or cleaning tools are difficult to reach deep into the rocking roller for cleaning due to the small distance between the two adjacent extrusion rods.

[0028] Optionally, the rotating disk is provided with a plurality of adjusting slots, and the plurality of adjusting slots extend along the rotating direction of the rotating disk, and the plurality of extrusion rods are respectively slidably engaged with the rotating disk through the respective adjusting slots; The rotating disk is coaxially rotated with a locking ring, and the locking ring is provided with a plurality of locking blocks, and the plurality of locking blocks are respectively slidably matched with each adjusting sliding groove.

[0029] By adopting the above technical solution, when the extrusion rod needs to be slid, the locking ring is rotated so that the locking blocks in each adjustment slide groove are respectively away from each extrusion rod, so that each extrusion rod has sufficient movable space for sliding, reducing the need for production personnel to adjust the fixation and movement of the extrusion rod back and forth. Instead, the fixation and movement of each extrusion rod can be adjusted simultaneously only by rotating the locking ring, and the operation difficulty is low.

[0030] In summary, this application includes at least one of the following beneficial technical effects: 1. When the powder discharge port is opened or closed or its opening is adjusted, the residual scattered powder will fall into the drawer chamber of the opening and closing drawer, and is not easy to fall from the surrounding of the opening and closing drawer, thereby reducing the occurrence of powder falling onto the table or the ground, which is conducive to reducing the waste of powder and improving the economic benefits of production; 2. For drug powder that sticks to the powder guide plate due to high humidity, the reciprocating rotation of the powder guide plate will cause the drug powder to be shaken into the granulation chamber, reducing drug powder waste and the cleaning workload of production personnel, with low costs and good production feedback; 3. The powder distribution tube helps reduce the height difference when the powder falls into the storage chamber, thus preventing the powder from being scattered around the swing granulator due to pressure during transportation, thereby reducing powder waste. Furthermore, by rotating the powder distribution tube, the supply of powder to two adjacent storage chambers can be controlled, which is low-cost and has a good production feedback.

[0044] The following is combined with Figure 1-13 This application is described in further detail.

[0045] Example 1: Example 1 of the present application discloses a swing type pellet machine. Figure 1 The swing granulator includes a frame, a powder delivery pipe 1, a powder storage hopper 2, a granulator body 3, and a granulator conveyor belt 4. The powder delivery pipe 1, the powder storage hopper 2, the granulator body 3, and the granulator conveyor belt 4 are fixedly mounted on the frame in a vertically downward direction. The granulator conveyor belt 4 is arranged horizontally to facilitate the transportation of the drug granules formed by the granulator body 3 to the subsequent workstations.

[0046] Reference Figure 2The input end of the powder conveying tube 1 is connected to a powder supply device (not shown), which is used to convey medicinal powder. A powder dispensing tube 11 is provided at the output end of the powder conveying tube 1. This dispensing tube 11 is rotatably coupled to the powder conveying tube 1 and tilted downward from top to bottom. This allows for rotation of the powder dispensing tube 11, causing the medicinal powder to fall from the bottom of the tube 11 at different levels. This allows for adjustment of the powder's landing point to meet various practical needs. Furthermore, a handle is provided on the tube 11 to facilitate rotation by production personnel.

[0047] Reference Figure 2 The powder storage hopper 2 is located at the bottom of the powder dispensing tube 11, and is positioned close to the bottom of the powder dispensing tube 11 to prevent powder from scattering and falling onto the countertop or floor. The powder storage hopper 2 has two storage chambers 201 arranged horizontally and interconnected at their tops, allowing powder to be transported to both chambers 201 via a single powder dispensing tube 11 when production requires it.

[0048] The powder storage hopper 2 is provided with a chamber dividing rib 21, which is located between the two storage chambers 201 and at the bottom of the powder dispensing tube 11. The top of the chamber dividing rib 21 is curved. By rotating the powder dispensing tube 11, the powder falls from the top of the chamber dividing rib 21 and is guided by the chamber dividing rib 21 so that the powder is simultaneously transported to two adjacent storage chambers 201. In some embodiments, the angle of the powder dispensing tube 11 can be adjusted so that the powder supply to one adjacent storage chamber 201 is greater than that to the other adjacent storage chamber 201. This facilitates the delivery of corresponding quotas of powder to workstations with different processing capacities via the multiple granule conveyor belts 4 when multiple granule conveyor belts 4 are provided.

[0049] A powder discharge port 202 is provided at the bottom of the powder storage hopper 2, and the powder discharge port 202 is connected to the storage chamber 201. The inner diameter of the powder discharge port 202 is smaller than the inner diameter of the storage chamber 201, so that the powder in the storage chamber 201 can be supplied according to production needs by controlling the opening and closing or opening degree of the powder discharge port 202.

[0050] The powder storage hopper 2 is slidably equipped with an opening / closing drawer 22 at the location of the powder discharge port 202. By pushing and pulling the opening / closing drawer 22, the powder discharge port 202 can be opened and closed, or the opening of the powder discharge port 202 can be controlled. A drawer chamber 221 is provided at the top of the opening / closing drawer 22. The drawer chamber 221 is used to hold powder that falls from the powder discharge port 202. Specifically, when the opening / closing drawer 22 closes the powder discharge port 202, the drawer chamber 221 is entirely connected to the powder discharge port 202. When the opening / closing drawer 22 opens the powder discharge port 202, the drawer chamber 221 is no longer connected to the powder discharge port 202, or is partially connected to the powder discharge port 202. This allows the sidewalls of the drawer chamber 221 to prevent scattered powder from falling around the opening / closing drawer 22, thereby reducing the amount of powder that falls onto a countertop or the ground, thereby reducing powder waste. In addition, in order to facilitate pushing and pulling the opening and closing drawer 22, a handle is fixedly connected to the front end of the opening and closing drawer 22 to facilitate the staff to apply force.

[0051] Reference Figure 3 The granulator body 3 includes a granulation tank 31 and two rocking rollers 32. A granulation chamber 301 is defined within the granulation tank 31. The granulation chamber 301 is located at the bottom of the opening and closing drawer 22, allowing drug powder to fall from the drug powder storage hopper 2 into the granulation chamber 301. A granulation screen 33 is also provided at the bottom of the granulation tank 31. The granulation screen 33 has mesh openings whose apertures match the particle size of the drug particles.

[0052] Two oscillating rollers 32 are located within the granulation chamber 301 and are arranged horizontally. The oscillating rollers 32 are rotatably coupled to the granulation tank 31. A motor (not shown) is provided in the granulation tank 31 to reciprocate the oscillating rollers 32. By switching the oscillating rollers 32 between clockwise and counterclockwise rotation, the oscillating rollers 32 squeeze the drug powder entering the granulation tank 31 and force it through the mesh of the granulation screen 33, thereby forming drug particles of a specific size.

[0053] Reference Figure 3 A powder guide plate 34 is provided on the top of the granulation trough body 31. The bottom of the powder guide plate 34 is rotatably fitted with the granulation trough body 31, and the top of the powder guide plate 34 is smoothly set. In normal conditions, the powder guide plate 34 is tilted from top to bottom toward the storage chamber 201, so that the powder falling to the outside of the granulation chamber 301 can be guided to the inside of the granulation chamber 301 by reciprocatingly rotating the powder guide plate 34, thereby reducing the waste of powder.

[0054] The operating principle of the oscillating granulator in Example 1 of the present application is as follows: a powder supply device delivers powder to the oscillating granulator, and transfers the powder to the storage chamber 201 via the powder delivery pipe 1 and the powder distribution pipe 11. When production personnel adjust the powder discharge port 202 according to production needs, the powder is blocked by the inner wall of the drawer chamber 221, thereby preventing the powder from falling onto the surrounding countertops or the ground, thereby reducing the waste of powder and ensuring the economic benefits of production.

[0055] Example 2: Example 2 of the present application discloses a swing-type pellet machine, which has the following main differences compared to Example 1.

[0056] Difference 1: Reference Figure 4 and Figure 5 The powder storage hopper 2 is also fixedly installed with a powder scraper 23, which is located inside the drawer chamber 221, and the powder scraper 23 fits the inner wall of the drawer chamber 221, so that the drawer chamber 221 is divided by the powder scraper 23 into a rear end chamber connected to the storage chamber 201 and a front end chamber close to the handle, thereby making it difficult for medicine powder to transfer from the rear end chamber to the front end chamber during the process of pushing and pulling the drawer 22 when opening and closing, thereby reducing the occurrence of medicine powder bouncing onto the table or the ground after falling into the rear end chamber.

[0057] Reference Figure 6 and Figure 7 A powder cleaning port 222 is provided through the opening and closing drawer 22. The powder cleaning port 222 is located in the rear end chamber of the powder storage hopper 2, and the powder cleaning port 222 is connected to the drawer chamber 221, so that the medicine powder falling into the drawer chamber 221 can leave the drawer chamber 221 through the powder cleaning port 222 under the push of the powder scraper 23.

[0058] The drawer 22 is pivotally connected to a cleaning opening closure plate 223 located at the location of the powder cleaning opening 222. The cleaning opening closure plate 223 is elastic and preferably made of sheet metal. A snap-fitting slot 224 is defined at the rear end of the drawer 22. This slot 224 allows the cleaning opening closure plate 223 to snap into engagement with the drawer 22, facilitating the closing of the powder cleaning opening 222 and preventing scattered powder from falling directly onto the surrounding area of ​​the drawer 22.

[0059] Difference 2: Reference Figure 8 and Figure 9The granulator body 3 is fixedly mounted with an adjustment substrate 35, and the adjustment substrate 35 is transparent so that the adhesion of the drug particles on the particle screen 33 can be identified through the adjustment substrate 35, and it is also convenient to prevent the scattering of drug particles, thereby reducing the waste of drug powder. The adjustment substrate 35 is provided with an air blowing chute 351, and the shape of the air blowing chute 351 is adapted to the bottom contour of the particle screen 33. Specifically, in Example 2 of the present application, the air blowing chute 351 is arranged in a "W" shape to adapt to the particle screen 33 of the two particle chambers. The air blowing chute 351 is slidably matched with two air blowing cleaning parts 5, and the two air blowing cleaning parts 5 are both used to blow gas to the particle screen 33, so that the adhering drug particles are blown away by the blown gas. Moreover, when there are many drug particles adhered to the particle screen 33, the two air blowing cleaning parts 5 can be slid to the location of the single particle screen 33 through the air blowing chute 351, and then the particle screen 33 can be cleaned by the two air blowing cleaning parts 5, thereby ensuring the cleaning effect of the particle screen 33.

[0060] Reference Figure 10 and Figure 11 The adjusting base plate 35 is fixedly mounted with a fixed hook 352, and the air-blowing cleaning member 5 is rotatably matched with a cleaning member hook 51, so that when the particle screen 33 does not need to be cleaned, the air-blowing cleaning member 5 can be temporarily fixed by the cleaning member hook 51, and it is also convenient for the production staff to act as a handle to apply force when sliding the air-blowing cleaning member 5. The air-blowing cleaning member 5 is provided with an air port 501 and an air inlet 502. There are several air ports 501, and the several air ports 501 are evenly distributed on the surface of the air-blowing cleaning member 5, and the several air ports 501 extend along the front and rear direction of the particle screen 33. The output end of the air inlet 502 is connected to each air port 501, and the input end of the air inlet 502 is used to connect to an air supply device such as an air pump through an air hose (not shown in the figure), so that air can be blown to clean various areas of the particle screen 33 through the several air ports 501.

[0061] Difference 3: Reference Figure 12 and Figure 13The rocking drum 32 includes two rotating disks 321 and a plurality of extrusion rods 322. The two rotating disks 321 are coaxially rotated and engaged with the granulator body 3. The plurality of extrusion rods 322 are located between the two rotating disks 321 and are circumferentially distributed around the axis of the rotating disks 321 to facilitate sufficient extrusion of the drug powder in the granulation chamber 301. The rotating disk 321 is provided with a plurality of adjustment chutes 323. The plurality of adjustment chutes 323 are distributed around the axis of the rotating disk 321 and extend along the circumference of the rotating disk 321. The plurality of extrusion rods 322 are slidably engaged with the rotating disk 321 through each adjustment chute 323, so that the gap between two adjacent extrusion rods 322 can be adjusted through each adjustment chute 323, thereby facilitating the cleaning of the extrusion rods 322 by production personnel.

[0062] A locking ring 36 is coaxially rotated with the side of the rotating disk 321 away from the extrusion rod 322. The locking ring 36 is fixedly connected to a plurality of locking blocks 361. The plurality of locking blocks 361 are slidably engaged with each adjustment slot 323. By rotating the locking ring 36, the locking blocks 361 can be tightly engaged with the extrusion rod 322 to maintain the stability of the extrusion rod 322, or the locking blocks 361 can be moved away from the extrusion rod 322, allowing the extrusion rod 322 to slide within the adjustment slot 323 and adjust the spacing. In addition, the locking ring 36 is also penetrated by a plurality of locking holes 362. When locking the extrusion rod 322 is required, the rotating disk 321 can be locked by bolts passing through the locking holes 362 and threadedly engaged with the rotating disk 321, thereby ensuring the stability of the extrusion rod 322.

[0063] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
