Description

Technical Field

[0001] This utility model relates to the field of capsule production equipment technology, and more specifically, it relates to a drying device for pharmaceutical excipients. Background Technology

[0002] Enteric-coated capsules are pharmaceutical preparations made using a specific process. Their capsule shells contain pharmaceutical-grade enteric materials. This dosage form has the characteristics of not disintegrating in gastric juice and being released in a targeted manner through intestinal juice, thus achieving the clinical value of reducing gastric mucosal irritation and avoiding drug degradation in the stomach.

[0003] Existing enteric-coated capsule production lines typically dip the capsules in adhesive at a dipping machine and then directly dry them after dipping. For example, Chinese invention patent application number 201410736476.1 describes a process where, after initial dipping, the capsules are conveyed to an upper drying tunnel for drying, then to a lower drying tunnel, and finally to a first coating machine for a second dipping. After the second dipping, the capsules are dried in the lower drying tunnel for a period of time before entering a second coating machine for a third dipping, and finally dried again in the lower drying tunnel to produce enteric-coated capsules. This method of directly drying the capsules after dipping in the coating machine leads to uneven capsule wall thickness, affecting the stability of the enteric-coated capsules. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a drying device for pharmaceutical excipients. The device uses a first flipping mechanism and a second flipping mechanism to flip the pharmaceutical excipient plate, allowing the enteric-coated capsules on the plate to roll and be evenly coated with the pharmaceutical excipient, ensuring uniform wall thickness of the enteric-coated capsules and improving their stability.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a drying device for dipping medicine excipients, comprising: a material plate flipping mechanism, a material plate conveying mechanism, a medicine dipping mechanism, a first flipping mechanism, a second flipping mechanism, and a drying mechanism; the material plate flipping mechanism is used to receive the material plate and flip it; the material plate conveying mechanism is disposed above the material plate flipping mechanism and is used to receive the material plate flipped by the material plate flipping mechanism and sequentially convey the material plate to the medicine dipping mechanism, the first flipping mechanism, the second flipping mechanism, and the drying mechanism; the medicine dipping mechanism is disposed below the material plate conveying mechanism and is used to pump glue onto the material plate; the first flipping mechanism is used to receive the material plate after glue pumping and flip it; the second flipping mechanism is used to receive the material plate flipped by the first flipping mechanism and flip it; and the drying mechanism is used to receive the material plate flipped by the second flipping mechanism and dry it.

[0006] Specifically, when applying medication to the outside of the enteric-coated capsules, the material plate carrying the capsules is flipped by a material plate flipping mechanism so that the opening of the material plate faces downwards. A drug-applying mechanism pumps a gel-like solution containing the medication into the opening of the material plate. The gel-like solution adheres to the inside of the material plate and covers the capsules. The material plate is then conveyed by a material plate conveying mechanism to a first flipping mechanism. The first flipping mechanism first flips the material plate so that the opening of the material plate faces upwards. Then, by rotating the material plate, the capsules roll within the material plate and are coated with the gel-like solution inside the material plate, ensuring that the gel-like solution is evenly adhered to the surface of each capsule. The material plate is then conveyed to a second flipping mechanism. The second flipping mechanism rotates the material plate, causing the capsules to roll within the material plate, ensuring that the capsules are coated with as much gel-like solution as possible. This two-stage flipping improves the uniformity of capsule adhesion. After the capsules are coated, the material plate conveying mechanism conveys the material plate flipped by the second flipping mechanism to a drying mechanism for drying, achieving the drying and hardening of the drug layer corresponding to the enteric-coated capsules.

[0007] Optionally, the material plate flipping mechanism includes: a flipping motor and a flipping rack; the flipping rack is provided with a material plate support for carrying the material plate, and the output end of the flipping motor is fixed to the flipping rack.

[0008] Specifically, the rotating material rack is driven by a rotating motor to rotate the material plate support on the rotating material rack by 180°, and the material plate supported on the material plate support is flipped so that the opening of the material plate faces downward, so that the drug dipping mechanism can pump the gel solution to the side of the material plate on which the capsules are placed.

[0009] Optionally, the dipping mechanism includes a lifting cylinder, a dipping plate, and a glue pump; the dipping plate is located at the output end of the lifting cylinder, the glue pump is located below the dipping plate, and a glue injection hole is provided on the dipping plate. The output end of the glue pump passes through the glue injection hole and injects glue onto the material plate on the dipping plate.

[0010] Specifically, the material plate conveying mechanism transports the material plate with the opening facing down to the dip plate and moves it above the glue injection hole. The lifting cylinder descends, allowing the output end of the glue pump to pass through the glue injection hole, and the glue pump pumps glue into the material plate.

[0011] Optionally, the first flipping mechanism includes: a first flipping motor, a first pulley assembly, and a first flipping bracket; the input end of the first pulley assembly is coaxially connected to the output end of the first flipping motor, and the output end of the first pulley assembly is fixed to the first flipping bracket; the first flipping bracket is provided with a fitting groove corresponding to the material plate.

[0012] Specifically, the material plate conveying mechanism pushes the material plate with its opening facing downwards into the fitting groove of the first flip plate bracket. The fitting groove limits the material plate, making the center of the material plate coincide with the rotation center of the first flip plate bracket. The first flip plate motor drives the first flip plate bracket to rotate, first resetting the material plate so that the opening of the material plate faces upwards, and then making the first flip plate bracket swing left and right with a certain swing amplitude, so that the capsules in the material plate roll back and forth in the material plate, thereby adhering the gel-like solution in the material plate to the capsules.

[0013] Optionally, the second flipping mechanism includes: a second flipping motor, a second pulley assembly, and a second flipping bracket; the input end of the second pulley assembly is coaxially connected to the output end of the second flipping motor, the output end of the second pulley assembly is fixed to the second flipping bracket, and the second flipping bracket is provided with a through groove corresponding to the material plate.

[0014] Specifically, after the first flipping mechanism flips, the opening of the fitting groove and the through groove are on the same horizontal line. The material plate is moved from the fitting groove to the through groove by the material plate conveying mechanism, and the center of the material plate coincides with the rotation center of the second flipping bracket. The second flipping plate motor drives the second flipping bracket to rotate, so that the second flipping bracket swings left and right with a certain swing amplitude, further improving the uniformity of the capsule adhesive.

[0015] Optionally, the material plate conveying mechanism includes: a first conveying component and a second conveying component; the first conveying component is disposed above the material plate flipping mechanism and the medicine dipping mechanism, and is used to convey the material plate on the material plate flipping mechanism to the medicine dipping mechanism and the first flipping mechanism in sequence; the second conveying component is disposed below the first flipping mechanism and the second flipping mechanism, and is used to convey the material plate on the first flipping mechanism to the second flipping mechanism and the drying mechanism in sequence.

[0016] Specifically, the first conveying component removes the material plate from the material plate flipping mechanism, pushes the material plate from the material plate support of the material plate flipping mechanism onto the medicine-dipping plate of the medicine-dipping mechanism, and moves the material plate to the glue-injection port. After the glue is injected into the material plate, the first conveying component pushes the material plate into the fitting groove on the first flipping support of the first flipping mechanism. After the first flipping mechanism completes the flipping of the material plate, the second conveying component removes the material plate from the fitting groove and sends it into the through groove on the second flipping support of the second flipping mechanism. After the second flipping mechanism completes the flipping of the material plate, the second conveying component removes the material plate from the through groove and conveys it to the drying mechanism.

[0017] Optionally, the first conveying component includes: a first linear motor and a first pusher frame; the first linear motor is disposed above the material plate flipping mechanism and the medicine dipping mechanism, the first pusher frame is disposed at the output end of the first linear motor, and at least one first pusher is disposed on the first pusher frame, the first pusher being used to sequentially convey the material plate on the material plate flipping mechanism to the medicine dipping mechanism and the first flipping mechanism.

[0018] Specifically, when moving the material plate, the first linear motor drives the first pusher frame to move linearly. The first pusher on the first pusher frame contacts the material plate and pushes the material plate to move along the conveying direction of the first linear motor, so as to realize the sequential conveying of the material plate in the material plate flipping mechanism to the medicine dipping mechanism and the first flipping mechanism.

[0019] Optionally, the second conveying component includes: a second linear motor and a second pusher frame; the second linear motor is disposed below the first flipping mechanism and the second flipping mechanism, the second pusher frame is disposed at the output end of the second linear motor, and at least one second pusher is disposed on the second pusher frame, the second pusher being used to convey the material plate on the first flipping mechanism to the second flipping mechanism and the drying mechanism in sequence.

[0020] Specifically, when moving the material plate, the second linear motor drives the second pusher frame to move linearly. The second pusher on the second pusher frame contacts the material plate and pushes the material plate to move along the conveying direction of the second linear motor, so as to convey the material plate on the first flipping mechanism to the second flipping mechanism and the drying mechanism in sequence.

[0021] Optionally, the drying mechanism includes: a drying chamber and a conveyor wheel assembly; the conveyor wheel assembly is disposed inside the drying chamber; a plurality of material trays are disposed on the conveyor wheel assembly; a plate holder for receiving the material trays conveyed by the conveyor wheel assembly is disposed at the outlet of the drying chamber; a pusher assembly is disposed inside the drying chamber, and the pusher assembly is used to push the material trays on the plate holder out of the drying chamber.

[0022] Specifically, the material plate conveying mechanism moves the material plate to the entrance of the drying chamber. At this time, the material plate tray on the conveying wheel assembly is at the same level as the through groove of the second flipping mechanism. The material plate conveying mechanism pushes the material plate to separate it from the through groove and place it on the material plate tray. The conveying wheel assembly drives the material plate tray to move back and forth in the drying chamber to ensure the drying time of the enteric-coated capsules on the material plate. When the conveying wheel assembly conveys the material plate to the exit of the drying chamber, the two ends of the material plate overlap on the plate holder. At this time, the material plate separates from the material plate tray. Then, the push plate assembly pushes the material plate on the plate holder out of the drying chamber. The material plate and the enteric-coated capsules on the material plate enter the next process.

[0023] In summary, this invention has the following beneficial effects: When applying medication to the outside of the enteric-coated capsules, the material plate carrying the capsules is flipped by a material plate flipping mechanism so that the opening of the material plate faces downwards. A gel-like solution containing medication is pumped into the opening of the material plate by a medication-applying mechanism. The gel-like solution adheres to the inside of the material plate and covers the capsules. The material plate is then conveyed to a first flipping mechanism by a material plate conveying mechanism. The first flipping mechanism first flips the material plate so that the opening faces upwards, and then rotates the material plate to make the capsules roll within the material plate, applying the gel-like solution evenly to the surface of each capsule. The material plate is then conveyed to a second flipping mechanism, which rotates the material plate to make the capsules roll within the material plate, ensuring that the capsules absorb as much of the gel-like solution as possible. These two flipping processes improve the uniformity of the capsule adhesion. After the capsules are glued, the material plate conveying mechanism conveys the material plate flipped by the second flipping mechanism to a drying mechanism for drying, achieving the drying and hardening of the drug layer corresponding to the enteric-coated capsules.

[0034] Specifically, when applying medication to the outside of the enteric-coated capsules, the material plate 9 carrying the capsules is flipped by the material plate flipping mechanism 1 so that the opening of the material plate 9 faces downward. The medication application mechanism 3 pumps a gel-like solution containing the medication into the opening of the material plate 9. The gel-like solution adheres to the inside of the material plate 9 and covers the capsules. The material plate conveying mechanism 2 then conveys the material plate 9 to the first flipping mechanism 4. The first flipping mechanism 4 first flips the material plate 9 so that the opening of the material plate 9 faces upward. Then, by rotating the material plate 9, the capsules roll inside the material plate 9 and are coated with the gel-like solution inside the material plate 9, so that the gel-like solution is evenly adhered to the surface of each capsule. The material plate 9 is then conveyed to the second flipping mechanism 5. The second flipping mechanism 5 rotates the material plate 9 so that the capsules roll inside the material plate 9, so that the capsules are coated with the gel-like solution inside the material plate 9 as much as possible. The uniformity of the capsule adhesion is improved by flipping the material plate twice. After the capsules are glued, the material plate conveying mechanism 2 conveys the material plate 9, which has been flipped by the second flipping mechanism, to the drying mechanism 6 for drying, thereby achieving the drying and hardening of the drug layer corresponding to the enteric-coated capsules.

[0037] The tilting rack 102 is equipped with two material plate 9 supports, which limit the two ends of the material plates 9 respectively. Each material plate 9 support has a receiving groove for limiting the material plates 9. The material plates 9 enter the material plate 9 supports through the receiving grooves. After the tilting motor 101 drives the tilting rack 102 to tilt, the opening of the receiving groove faces the medicine-dipping mechanism 3. The material plate conveying mechanism 2 pushes the material plates 9 to separate them from the receiving grooves and enter the medicine-dipping mechanism 3.

[0039] Specifically, the material plate conveying mechanism 2 conveys the material plate 9 with the opening facing downwards to the dip plate 32 and moves it above the glue injection hole.

[0041] Specifically, the material plate conveying mechanism 2 pushes the material plate 9 with its opening facing downwards into the fitting groove 7 of the first flip plate bracket 43. The fitting groove 7 limits the material plate 9, so that the center of the material plate 9 coincides with the rotation center of the first flip plate bracket 43. The first flip plate motor 101 drives the first flip plate bracket 43 to rotate, first resetting the material plate 9 so that the opening of the material plate 9 faces upwards, and then making the first flip plate bracket 43 swing left and right with a certain swing amplitude, so that the capsules in the material plate 9 roll back and forth in the material plate 9, thereby adhering the gel-like solution in the material plate 9 to the capsules.

[0042] There are two first flip plate brackets 43, which are coaxially connected. Each of the two first flip plate brackets 43 is provided with a fitting groove 7, which restricts the two ends of the material plate 9 respectively.

The gel-like solution adheres to the inside of the material plate 9 and covers the capsules. The material plate conveying mechanism 2 then conveys the material plate 9 to the first flipping mechanism 4. The first flipping mechanism 4 first flips the material plate 9 so that the opening of the material plate 9 faces upward. Then, by rotating the material plate 9, the capsules roll inside the material plate 9 and are coated with the gel-like solution inside the material plate 9, so that the gel-like solution is evenly adhered to the surface of each capsule.

Each material plate 9 support has a receiving groove for limiting the material plates 9. The material plates 9 enter the material plate 9 supports through the receiving grooves. After the tilting motor 101 drives the tilting rack 102 to tilt, the opening of the receiving groove faces the medicine-dipping mechanism 3. The material plate conveying mechanism 2 pushes the material plates 9 to separate them from the receiving grooves and enter the medicine-dipping mechanism 3.

[0062] Optionally, the first conveying assembly 21 includes: a first linear motor 211 and a first pusher frame 212; the first linear motor 211 is disposed above the material plate flipping mechanism 1 and the medicine dipping mechanism 3, the first pusher frame 212 is disposed at the output end of the first linear motor 211, and at least one first pusher 213 is disposed on the first pusher frame 212, the first pusher 213 being used to sequentially convey the material plate 9 on the material plate flipping mechanism 1 to the medicine dipping mechanism 3 and the first flipping mechanism 4.

[0063] Specifically, when moving the material plate 9, the first linear motor 211 drives the first push plate frame 212 to move linearly. The first push plate 213 on the first push plate frame 212 contacts the material plate 9 and pushes the material plate 9 to move along the conveying direction of the first linear motor 211, so as to convey the material plate 9 in the material plate flipping mechanism 1 to the medicine dipping mechanism 3 and the first flipping mechanism 4 in sequence.

[0064] Optionally, the second conveying assembly 22 includes: a second linear motor 221 and a second pusher frame 222; the second linear motor 221 is disposed below the first flipping mechanism 4 and the second flipping mechanism 5, the second pusher frame 222 is disposed at the output end of the second linear motor 221, and at least one second pusher 223 is disposed on the second pusher frame 222, the second pusher 223 being used to sequentially convey the material plate 9 on the first flipping mechanism 4 to the second flipping mechanism 5 and the drying mechanism 6.

[0065] Specifically, when moving the material plate 9, the second linear motor 221 drives the second pusher frame 222 to move linearly. The second pusher 223 on the second pusher frame 222 contacts the material plate 9 and pushes the material plate 9 to move along the conveying direction of the second linear motor 221, so as to convey the material plate 9 on the first flipping mechanism 4 to the second flipping mechanism 5 and the drying mechanism 6 in sequence.

[0066] Optionally, the drying mechanism 6 includes: a drying chamber 61 and a conveyor wheel assembly 62; the conveyor wheel assembly 62 is disposed inside the drying chamber 61; a plurality of material trays 63 are disposed on the conveyor wheel assembly 62; a plate holder 64 for receiving the material plates 9 conveyed by the conveyor wheel assembly 62 is disposed at the outlet of the drying chamber 61; a pusher assembly 65 is disposed inside the drying chamber 61, and the pusher assembly 65 is used to push the material plates 9 on the plate holder 64 out of the drying chamber 61.

[0067] Specifically, the material plate conveying mechanism 2 moves the material plate 9 to the entrance of the drying chamber 61. At this time, the material plate tray 63 on the conveying wheel assembly 62 is at the same level as the through groove 8 of the second flipping mechanism 5. The material plate conveying mechanism 2 pushes the material plate 9 to separate the material plate 9 from the through groove 8 and place it on the material plate tray 63. The conveying wheel assembly 62 drives the material plate tray 63 to move back and forth in the drying chamber 61 to ensure the drying time of the enteric-coated capsules on the material plate 9. When the conveying wheel assembly 62 conveys the material plate 9 to the exit of the drying chamber 61, the two ends of the material plate 9 overlap on the plate holder 64. At this time, the material plate 9 is separated from the material plate tray 63. Then, the push plate assembly 65 pushes the material plate 9 out of the drying chamber 61 from the plate holder 64. The material plate 9 and the enteric-coated capsules on the material plate 9 enter the next process.

[0068] The conveyor wheel assembly 62 includes one driving wheel and six driven wheels. The driving wheel is connected to the output of the motor via a pulley assembly. The six driven wheels are arranged sequentially inside the drying chamber 61, with each adjacent driven wheel having a height difference. A conveyor belt is wound around the driving wheel and the six driven wheels. The material tray 63 is mounted on the conveyor belt and hinged to it, thereby keeping the material plate 9 in a horizontal position at all times. The material tray 63 is slightly smaller than the width of the material plate 9, only supporting the bottom of the material plate 9, and can pass through the hollow part of the plate holder 64, allowing the two ends of the material plate 9 to overlap on the plate holder 64. The pusher assembly 65 is a device capable of pushing the material plate 9 linearly. In this embodiment, a linear motor is used, but in other embodiments, a cylinder can also be used.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
