Description

Technical Field

[0001] This utility model relates to the field of de-packing machine technology, and in particular to a de-packing machine threshing structure and a de-packing machine. Background Technology

[0002] In hospital pharmacies and other similar facilities, it is often necessary to unpack large quantities of blister packs to obtain granules. This manual process is laborious, time-consuming, and inefficient.

[0003] In addition to the packaging machine, pressure rollers can be used to press the drug granules out. Different blister pack sizes result in different column spacing of drug granules. To accommodate blister packs with different spacing, the spacing of the pressure plates needs to be adjusted so that the spacing of the pressure plates matches the column spacing of the drug granules on the blister pack.

[0004] Adjusting the spacing between pressure plates usually requires manual adjustment one by one, or the pressure plates need to be removed, which is inconvenient, time-consuming, and results in inaccurate spacing. Utility Model Content

[0032] In an optional embodiment, the de-threshing structure of the de-packing machine further includes:

[0033] Two sets of positioning components are provided on the housing, wherein at least one set of positioning components is slidably disposed on the housing to adjust the distance between the two sets of positioning components according to the size of the blister pack.

Detailed Implementation

[0060] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0061] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended meaning of inclusion and that other elements / components / etc. may exist in addition to the listed elements / components / etc.

[0062] In this embodiment of the invention, front, back, left, and right are defined as follows: When the parcel locker is in use, the direction facing the user is front, and the opposite direction is back. When the user faces the parcel locker, the left side is left, and the right side is right.

[0063] See Figures 1 to 9 This utility model provides a threshing structure for a de-packing machine, including an adjusting shaft assembly 2 and multiple pressure plate assemblies 3. The adjusting shaft assembly 2 includes an adjusting shaft 21 rotatably mounted on a housing 1. The adjusting shaft 21 is rotatable relative to the housing 1. Multiple pressure plate assemblies 3 are parallel to each other and slidably mounted on the housing 1. The pressure plate assemblies 3 slide on the housing 1, allowing for adjustable spacing. The pressure plate assemblies 3 are drively connected to the adjusting shaft 21. When the adjusting shaft 21 rotates, it drives the multiple pressure plate assemblies 3 to slide, changing the spacing of the pressure plate assemblies 3 while maintaining an equal spacing. The spacing of the pressure plate assemblies 3 can be adjusted by rotating the adjusting shaft 21 without disassembling them, making it convenient, quick, and easy to operate.

[0064] See Figure 2 The adjusting shaft 21 has multiple spiral grooves 22. (See also...) Figure 3 The pressure plate assembly 3 includes a follower component 31. Each pressure plate assembly 3 corresponds to a spiral groove 22. The follower component 31 is slidably disposed within the corresponding spiral groove 22. The follower component 31 slides along the spiral groove 22 as the adjusting shaft 21 rotates, thereby causing the spacing between the pressure plate assemblies 3 to change, and the multiple pressure plate assemblies 3 maintain an equal spacing arrangement. The pressure plate assembly 3 achieves a transmission connection with the adjusting shaft 21 through the sliding engagement of the follower component 31 and the spiral groove 22. When the follower component 31 slides along the spiral groove 22, its position in the axial direction of the adjusting shaft 21 changes, thereby driving the pressure plate assembly 3 to slide along the axial direction of the adjusting shaft 21. When each pressure plate assembly 3 moves under the drive of the adjusting shaft 21, the distance it slides along the axial direction of the adjusting shaft 21 is different, so that while the spacing of the pressure plate assemblies 3 changes, the multiple pressure plate assemblies 3 maintain an equal spacing arrangement.

[0065] When the adjusting shaft 21 rotates in the first direction, the distance between the pressure plate assemblies 3 increases. When the adjusting shaft 21 rotates in the second direction, the distance between the pressure plate assemblies 3 decreases. One of the first and second directions is clockwise, and the other is counterclockwise. For example, if the adjusting shaft 21 rotates counterclockwise, the distance between the pressure plate assemblies 3 increases; if it rotates clockwise, the distance between the pressure plate assemblies 3 decreases. Based on the column spacing of the pills on the blister pack 8, the adjusting shaft 21 is rotated to make the distance between the pressure plate assemblies 3 match the column spacing of the pills. The pressure plate assemblies 3 are aligned between two rows of pills, and the pressure roller 4 squeezes one side of the blister pack, extruding the pills.

[0066] In some embodiments, see Figure 2 The starting points 221 of multiple spiral grooves 22 are arranged at equal intervals along the first generatrix on the circumference of the adjusting shaft 21, and the starting points 221 of the multiple spiral grooves 22 are arranged from the first end to the second end of the adjusting shaft 21. Multiple pressure plate assemblies 3 are arranged at equal intervals along the axial direction of the adjusting shaft 21, and the follower components 31 of the multiple pressure plate assemblies 3 are arranged along the axial direction of the adjusting shaft 21. The starting points 221 of the multiple spiral grooves 22 are on the first generatrix, and the follower components 31 of the multiple pressure plate assemblies 3 can simultaneously move along their respective spiral grooves 22 to their respective starting points 221.

[0067] The endpoints 222 of the multiple spiral grooves 22 are arranged at equal intervals along the second generatrix on the circumference of the adjusting shaft 21. The follower components 31 of the multiple pressure plate assemblies 3 can move simultaneously to their respective endpoints 222 along their respective spiral grooves 22.

[0068] The end point 222 of each spiral groove 22 is closer to the second end relative to the starting point 221. When the follower component 31 of each pressure plate assembly 3 is located at the starting point 221 of the corresponding spiral groove 22, each pressure plate assembly 3 is located at its first end closest to the adjusting shaft 21, and the distance between each pressure plate assembly 3 is at the minimum adjustable range. When the adjusting shaft 21 rotates in the first direction, the follower component 31 slides along the corresponding spiral groove 22, causing each pressure plate assembly 3 to move axially towards the second segment along the adjusting shaft 21, and the distance between each pressure plate assembly 3 gradually increases while maintaining an equal spacing. When the follower component 31 slides to the end point 222, each pressure plate assembly 3 is located at its second end closest to the adjusting shaft 21, and the distance between each pressure plate assembly 3 is at the maximum adjustable range.

[0069] Conversely, when the adjusting shaft 21 rotates in the second direction, the follower component 31 slides along the corresponding spiral groove 22 from the end point 222 to the starting point 221, causing each pressure plate assembly 3 to move axially towards the first end along the adjusting shaft 21, and the distance between each pressure plate assembly 3 gradually decreases while maintaining an equal spacing arrangement.

[0070] When the spiral groove 22 moves one unit arc in the circumferential direction, the axial distance L it moves satisfies the following formula: L = nm, where n is the sequence number of the spiral groove 22. Multiple spiral grooves 22 are ordered sequentially from 1 to the second end of the adjusting shaft 21, following the order of the starting point 221. m is the base feed amount, determined by the spiral groove 22 with sequence number 1. In this invention, the spiral groove 22 with sequence number 1 can be designed first, and then the subsequent spiral grooves can be designed sequentially, ensuring that the axial distance moved by each unit arc of the spiral groove satisfies L = nm. The specific value of one unit arc is not limited; the smaller the specific value of one unit arc, the higher the accuracy of adjusting the spacing of the pressure plate assembly 3.

[0071] In some embodiments, the lead angle of the spiral groove 22 with serial number 1 can remain constant. If the spiral groove 22 with serial number 1 moves one unit radian circumferentially, the distance it moves axially remains constant. When machining the spiral groove 22 with serial number 1 using a cutting method, the movement of the tool in the feed direction can be uniform. When machining spiral grooves 22 with subsequent serial numbers, the movement of the tool in the feed direction can be accelerated, with the acceleration gradually increasing. The change in acceleration can be determined using L = nm. The later the serial number, the greater the unit increase in the acceleration of the tool's movement in the feed direction.

[0072] In some embodiments, the lead angle of the spiral groove 22 with serial number 1 can gradually increase from the starting point 221 to the ending point 222. When machining the spiral groove 22 with serial number 1, the movement of the tool in the feed direction can be an accelerating movement with the acceleration gradually increasing.

[0073] In some embodiments, on the same generatrix, the lead angle of the spiral groove 22 with a larger serial number is greater than that of the spiral groove 22 with a smaller serial number. The larger the lead angle of the spiral groove 22, the greater the distance that the pressure plate assembly 3 can move axially by rotating the adjusting shaft 21 by a unit angle, thereby enabling multiple pressure plate assemblies 3 to maintain an equal spacing while adjusting the spacing of the pressure plate assemblies 3.

[0074] In some embodiments, see Figure 3 The pressure plate assembly 3 also includes a movable body 32 and a pressure roller 33. The movable body 32 is slidably sleeved on at least two first guide shafts 34, and the two ends of the first guide shafts 34 are respectively connected to the housing 1. The at least two first guide shafts 34 enable the pressure plate assembly 3 to move only along the axial direction of the adjusting shaft 21, and the movable bodies 32 remain parallel to each other. The first guide shafts 34 and the adjusting shaft 21 are arranged in parallel.

[0075] The pressure roller 33 is rotatably positioned at the front end of the moving body 32. During depackaging, the pressure roller 33 is located on the back of the blister pack and between two rows of pills. The pressure roller 4 can squeeze the blister pack on one side to expel the pills. The pill liner 8 is held between the pressure roller 4 and the pressure roller 33. The pressure roller 4 rotates and squeezes the pill liner 8, and under the action of friction, it drives the pill liner 8 to move, thereby expelling all the pills. When the pressure roller 4 drives the pill liner 8 to move, the pressure roller 33 rotates, which can reduce the resistance to the pill liner 8 and enable the pill liner 8 to move smoothly, avoiding tilting of the pill liner 8.

[0076] The movable body 32 can be basically a plate.

[0077] The follower component 31 is disposed on the moving body 32. The follower component 31 may be disposed at the bottom of the moving body 32. The adjusting shaft 21 is disposed below the moving body 32, and the follower component 31 is located in the corresponding spiral groove 22.

[0078] The follower component 31 may include a cam follower. In a specific implementation, the cam follower may include a bearing. The bearing makes rolling contact with the groove wall of the helical groove 22.

[0079] In an exemplary embodiment, the outer peripheral surface of the pressure roller 33 is provided with a large coating or a structure for increasing friction. By increasing the friction on the outer peripheral surface of the pressure roller 33, the pressure on the medicine plate 8 can be made more uniform. The large coating for increasing friction may include an elastic layer, and the material of the elastic layer may include rubber or silicone. The structure for increasing friction, the pressure roller 33 may include a toothed structure, a patterned structure, and a raised structure. For example, the pressure roller 33 may be a gear.

[0080] The pressure plate assembly 3 also includes an adjusting positioning component 35, which is located at the rear end of the movable body 32 and is used to position itself relative to the gap on the medicine plate 8 when adjusting the spacing of the pressure plate assembly 3. When adjusting the gap of the pressure plate assembly 3, the medicine plate 8 can be placed behind the movable body 32. As the spacing of the pressure plate assembly 3 changes, the corresponding position of the adjusting positioning component 35 and the medicine plate 8 changes. When the gap between the adjusting positioning component 35 and the medicine particles on the medicine plate 8 is aligned, the gap of the pressure plate assembly 3 is consistent with the column spacing of the medicine particles.

[0081] The adjusting positioning element 35 can be an integral structure with the moving body 32. The adjusting positioning element 35 can be a thin or slender structure formed at the rear end of the moving body 32.

[0082] Of course, when adjusting the gap of the pressure plate assembly 3, the medicine plate 8 can also be placed in front of the moving body 32, and the pressure roller 33 can be aligned with the gap on the medicine plate 8.

[0083] In some embodiments, see Figure 1The adjusting shaft assembly 2 also includes a knob 23, which is located at one end of the adjusting shaft body 21 and is used to rotate the adjusting shaft body 21. The user can turn the knob 23 by hand to rotate the adjusting shaft body 21, thereby adjusting the spacing of the pressure plate assembly 3.

[0084] In some embodiments, see Figure 4 The threshing structure of this utility model embodiment includes a pressure roller 4, which is rotatably mounted on the machine housing 1. The pressure roller 4 contacts the pressure plate assembly 3 to clamp the medicine plate 8 between the pressure roller 4 and the pressure plate assembly 3, and enables the pressure roller 4 to drive the medicine plate 8 to move.

[0085] In specific implementation, the pressure plate assembly 3 includes a pressure roller 33, and a pressure roller 4 is drivenly connected to the pressure roller 33. The cooperation between the pressure roller 4 and the pressure roller 33 enables the smooth movement of the medicine plate 8. The pressure roller 4 is parallel to the first guide shaft 34, and each pressure roller 33 is drivenly connected to the pressure roller 4, enabling the pressure roller 4 to drive the pressure roller 33 to rotate. The medicine plate 8 is clamped between the pressure roller 4 and the pressure roller 33, so that the pressure roller 4 can drive the medicine plate 8 to move, thereby removing the medicine particles from the entire medicine plate 8.

[0086] In some embodiments, the pressure roller 33 has a first tooth on its circumferential surface, and the pressure roller 4 has a second tooth on its circumferential surface that meshes with the first tooth, with the pressure roller 4 meshing with the pressure roller 33. The meshing and transmission between the pressure roller 4 and the pressure roller 33 allows the medicine plate 8 to move smoothly, preventing tilting. Furthermore, the pressure roller 4, made of a metal roller shaft with a second tooth, is less prone to wear and tear, eliminating the need for replacement and saving on operating costs.

[0087] In some embodiments, see Figure 9 The threshing structure of this embodiment includes a drive assembly 7. The drive assembly 7 may include a rocker arm, which is connected to the pressure roller 4 via a transmission connection. The pressure roller 4 is rotated by manually rotating the rocker arm.

[0088] The drive assembly 7 may include a motor, which is connected to the pressure roller 4 via a transmission connection. The motor may be connected to the pressure roller 4 via at least one of the following: gears, belts, chains, etc.

[0089] In some embodiments, see Figures 4 to 6 The adjustment structure of this embodiment further includes a locking mechanism 5, which is connected to the housing 1 and is used to circumferentially fix the adjustment shaft 21 to the housing 1, or to release the circumferential fixation between the adjustment shaft 21 and the housing 1. When adjusting the spacing of the pressure plate assembly 3, the locking mechanism is operated to release the circumferential fixation between the adjustment shaft 21 and the housing 1, allowing the adjustment shaft 21 to rotate. After adjustment, the locking mechanism is operated to circumferentially fix the adjustment shaft 21 to the housing 1, preventing the adjustment shaft 21 from rotating, and the spacing of the pressure plate assembly 3 remains unchanged.

[0090] In some embodiments, see Figure 5 and Figure 6 The locking mechanism 5 includes a first locking member 51, which is disposed on the housing 1 and can move relative to the housing 1 between a first position and a second position.

[0091] In the first position, the first locking member 51 is connected to the adjusting shaft assembly 2 to circumferentially fix the adjusting shaft assembly 2 to the housing 1.

[0092] In the second position, the first locking member 51 is not connected to the adjusting shaft assembly 2, and the adjusting shaft assembly 2 and the housing 1 can rotate.

[0093] The first locking member 51 has a locking end for connecting to the adjusting shaft assembly 2 to circumferentially lock the adjusting shaft assembly 2.

[0094] The first locking member 51 may be slidably disposed on the housing 1 and move in a direction perpendicular to the adjusting shaft 21. When moving from the second position to the first position, the locking end gradually approaches the adjusting shaft assembly 2 and connects with the adjusting shaft assembly 2 at the first position. When the first locking member 51 moves from the first position to the second position, the locking end disengages from the adjusting shaft assembly 2, and the adjusting shaft assembly 2 can rotate.

[0095] The first locking member 51 can also be rotatably mounted on the housing 1. When the first locking member 51 rotates from the second position to the first position, the locking end gradually approaches the adjusting shaft assembly 2 and connects with the adjusting shaft assembly 2 at the first position. When the first locking member 51 rotates from the first position to the second position, the locking end disengages from the adjusting shaft assembly 2, and the adjusting shaft assembly 2 can rotate.

[0096] The locking mechanism 5 may include a fixed base 53, which is connected to the housing 1.

[0097] In some embodiments, see Figure 5 and Figure 6 The locking mechanism 5 includes a retainer 54 for holding the first locking member 51 in a first position and / or a second position.

[0098] The retaining member 54 may include at least one of a magnetic component and a spring. The magnetic component may be disposed on the first locking member 51 and / or the housing 1. In an exemplary embodiment, the magnetic component includes a first magnetic attractant and a second magnetic attractant, which are respectively disposed on the first locking member 51 and the housing 1. When the first locking member 51 needs to be held in one of the first and second positions, the retaining member 54 may be provided only on one side of the rotation axis of the first locking member 51. When the first locking member 51 needs to be held in both the first and second positions, retaining members 54 may be provided on both sides of the rotation axis of the first locking member 51. For example, a set of magnetic components may be provided on both sides of the rotation axis of the first locking member 51. The connection method between the retaining member 54 and the first locking member 51 and the housing 1 includes at least one of interference fit, bonding, and threaded connection. For example, the magnetic component may be threadedly connected to the first locking member 51 or the housing 1 using a screw structure. See also Figure 5 When the first locking member 51 is in the first position, the magnetic force between the magnetic components below the rotation axis of the first locking member 51 holds the first locking member 51 in the first position. See also Figure 6 When the first locking member 51 is in the second position, the magnetic force between the magnetic components above the rotation axis of the first locking member 51 keeps the first locking member 51 in the second position.

[0099] When the first locking member 51 or the housing 1 is made of magnetic material, a permanent magnet can be provided only on the first locking member 51 or the housing 1 as the first magnetic attracting member, and the first locking member 51 or the housing 1 made of magnetic material can be used as the second magnetic attracting member. When the first locking member 51 or the housing 1 is made of non-magnetic material such as aluminum, a second magnetic attracting member can be provided separately.

[0100] The spring may include a torsion spring and a coil spring. The torsion spring may be located on the rotation axis of the first locking member 51. The coil spring may be located between the first locking member 51 and the housing 1, with one end connected to the first locking member 51 and the other end connected to the housing 1.

[0101] The first locking member 51 is connected to the adjusting shaft assembly 2, and the adjusting shaft 21 can be circumferentially fixed to the housing 1 by friction.

[0102] The first locking member 51 and the adjusting shaft assembly 2 can also be used to circumferentially fix the adjusting shaft body 21 to the housing 1 through tooth engagement. In an exemplary embodiment, the locking mechanism 5 includes a second locking member 52, which is fixed to the adjusting shaft assembly 2. The second locking member 52 has a second tooth and a first tooth on its locking end. The rotation axis of the first locking member 51 is perpendicular to the adjusting shaft body 21. In a first position, the locking end engages with the second locking member 52; in a second position, the locking end disengages from the second locking member 52.

[0103] In some embodiments, see Figure 4 and Figure 7The adjustment structure of this embodiment further includes two sets of positioning components 6, which are disposed on the housing 1. At least one set of positioning components 6 is slidably disposed on the housing 1 to adjust the distance between the two sets of positioning components 6 according to the size of the blister pack 8. Each end of the positioning component 6 has a positioning groove 61 for insertion into the sides of the blister pack 8, and the positioning grooves 61 at the ends of the two sets of positioning components 6 correspond to each other. In this embodiment, one set of positioning components 6 can be slidably disposed on the housing 1. By sliding relative to the housing 1, the distance between the two sets of positioning components 6 can be adjusted to accommodate blister packs 8 of different sizes. In use, the distance between the two sets of positioning components 6 can be adjusted first so that the sides of the blister pack 8 are inserted into the corresponding positioning grooves 61, and the inner surfaces of the positioning components 6 abut against the blister packs on the blister pack 8, thereby limiting the left and right movement of the blister pack 8. After adjusting and fixing the distance between the two sets of positioning components 6, the spacing between the pressure plate assemblies 3 is adjusted. After the spacing between the pressure plate assemblies 3 is adjusted, the unpacking operation can be performed.

[0104] The depth of the positioning groove 61 is greater than the width of the edge of the blister pack 8, so as to ensure that the inner wall surface of the positioning component 6 can abut against the blister pack when various types of blister packs 8 are inserted into the positioning groove 61.

[0105] The positioning component 6 includes a positioning block 62, which is slidably sleeved on the second guide shaft 63.

[0106] In some embodiments, see Figure 4 The positioning component 6 includes at least two second guide shafts 63, which are parallel to the housing 1 and parallel to the adjusting shaft 21. A positioning block 62 is slidably engaged with the second guide shafts 63. The positioning block 62 may be slidably sleeved on the second guide shafts 63. A linear bearing may be provided between the positioning block 62 and the second guide shafts 63. The linear bearing allows the positioning block 62 to slide smoothly.

[0107] In some embodiments, see Figure 4 The positioning component 6 includes a positioning shaft 64 and a locking mechanism 65. The positioning shaft 64 is located on the housing 1, passes through the positioning block 62, and is parallel to the adjusting shaft 21.

[0108] In some embodiments, see Figure 8 The positioning component 6 includes a locking mechanism 65, which is mounted on the positioning block 62 and used to fix the positioning block 62 relative to the housing 1. In a specific implementation, the locking mechanism 65 can be fixed to the positioning shaft 64, thereby fixing the positioning block 62 relative to the housing 1. By setting the positioning shaft 64 and the locking mechanism 65, the locking mechanism 65 can be fixed or released from the positioning shaft 64, allowing the positioning block 62 to be fixed relative to the housing 1 or to move relative to it. This ensures smooth movement of the positioning block 62 and prevents the locking mechanism 65 from damaging the second guide shaft 63, thus affecting the movement of the positioning block 62.

[0109] In some embodiments, see Figure 8 The positioning block 62 has a locking groove, and a locking cover 66 is provided at the opening of the locking groove to close the locking groove. The positioning shaft 64 passes through the locking groove. The locking mechanism 65 includes a moving block 652 and a locking wheel 651. The moving block 652 is located in the locking groove. The moving block 652 can move within the locking groove to approach or move away from the positioning shaft 64. The moving block 652 can approach and contact the positioning shaft 64, thereby fixing it relative to the positioning shaft 64. After the moving block 652 moves away from and separates from the positioning shaft 64, the positioning block 62 can move relative to the housing 1 along the second guide shaft 63.

[0110] The locking screw 651 includes a locking screw that engages with a threaded hole on the locking cover 66. The screw rotates circumferentially with the movable block 652 while remaining axially fixed, thereby causing the movable block 652 to abut against or disengage from the positioning shaft 64. When the locking screw is rotated, due to its threaded engagement with the locking cover 66, the locking screw moves axially relative to the housing 1, thereby causing the movable block 652 to move together. This allows the movable block 652 to either approach and abut against the positioning shaft 64 and remain fixed, or move away from the positioning shaft 64 and separate from it.

[0111] In some embodiments, see Figure 8 The locking mechanism 65 also includes at least two parallel guide posts 653. One end of each guide post 653 is connected to the positioning block 62, and the other end is connected to the lock cover 66. The moving block 652 is slidably mounted on the guide post 653. The guide posts 653 allow the moving block 652 to slide along them, reducing the sliding resistance of the moving block 652. A linear bearing can be installed between the moving block 652 and the guide post 653 to further reduce the sliding resistance of the moving block 652.

[0112] Of course, in this embodiment of the invention, the locking mechanism 65 may not be provided, and the positioning block 62 can be held in the target position by friction. After the positioning block 62 is moved to the target position according to the size of the blister pack 8, the positioning block 62 remains relatively stationary by friction. During the unpacking operation, the force on the positioning block 62 is insufficient to counteract the friction, thus allowing the positioning block 62 to remain relatively stationary.

[0113] See Figure 10During packaging operations, the spacing of the positioning components 6 can be adjusted according to the size of the blister pack 8. When the positioning components 6 are adjusted to the target position, the positioning block 62 is fixed relative to the housing 1 by the locking mechanism 65. The blister pack 8 is inserted into the positioning groove on one side of the adjusting positioning component. The locking mechanism is adjusted to release the circumferential fixation between the adjusting shaft 21 and the housing 1. By rotating the knob, the adjusting shaft 21 is rotated, and the follower components slide along their respective spiral grooves, thereby changing the spacing of the pressure plate assembly 3 until the adjusting positioning component 35 is aligned with the two rows of pills. The locking mechanism is adjusted again to fix the adjusting shaft 21 circumferentially to the housing 1.

[0114] See Figure 11 Insert the blister pack 8 into the positioning groove on one side of the pressure roller 33, with the blister facing the pressure roller 4. Start the motor, which drives the pressure roller 4 to rotate. The blister pack 8, held between the pressure roller 4 and the pressure roller 33, moves accordingly. The pressure roller 4 squeezes the blister, extruding the medicine particles. The extruded medicine particles are aligned with the gap between the two pressure rollers 33, thus ensuring that the medicine particles in the blister pack 8 are not crushed or flattened.

[0115] In some embodiments, a storage box is provided on the casing, located below the pressure roller, for holding the granules. A guide bar is provided above the storage box to guide the extruded granules to the storage box. The guide bar is gradually inclined upwards away from the storage box. Under the influence of gravity, the granules roll onto the inclined surface of the guide bar to the storage box. A filter plate is provided above the storage box, with grooves and / or holes for the passage of granules. The extruded granules roll along the guide bar onto the filter plate and enter the storage box through the grooves or holes in the filter plate. Empty blister packs 8 are blocked by the filter plate and slide down it. A storage box can be provided near the storage box to store empty blister packs 8.

[0117] The housing 1 may include a base and two side walls disposed opposite to each other on the base. An adjusting shaft assembly 2 is rotatably connected to the two side walls. A pressure plate assembly 3 is slidably disposed between the two side walls. A cover 11 may also be provided on the housing 1. The cover 11 may be made of a transparent or translucent material.
