Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, and in particular to a coating device for the production of vonoprazan fumarate tablets. Background Technology

[0002] Vonoprazan fumarate improves mood and reduces anxiety by inhibiting the reuptake of neurotransmitters norepinephrine and serotonin, thereby increasing their concentration in the brain. Coating machines are mainly used for coating tablets, capsules, etc. By forming a uniform film on the surface of the tablet core, the stability of the drug can be increased, unpleasant odors can be masked, and side effects can be reduced. The main working principle of the coating machine is to spray the coating solution onto the surface of the rolling tablet core, and then evaporate the solvent through the evaporation of hot air, thereby forming a polymer film on the surface of the tablet core.

[0003] A pill coating device, disclosed in CN221600659U, includes two support plates. A device body is fixedly mounted on the top of each support plate. A coating pan body is positioned above one side of the device body. A discharge plate is located on the lower side of the outer surface of the coating pan body. Through the coordinated use of the coating pan body, the discharge plate, protrusions, limiting plates, sliding plates, limiting blocks, limiting grooves, springs, arc-shaped sliding grooves, and fixed plates, the discharge plate solves the problem of inconvenient pill removal. The discharge plate makes the pill removal process more convenient and faster. With its reasonable design and limiting structure, the discharge plate can be operated when pill removal is needed. However, existing coating devices generally have poor tablet turning effects, and tablets located at the bottom of the pan cannot be well coated, often requiring rework, wasting a lot of time and affecting production efficiency.

[0022] like Figure 1-3As shown, this utility model discloses a coating device for producing vonoprazan fumarate tablets, comprising: a coating pan 1 connected to a mounting box 2, with a control box inside the mounting box 2; a base 3 connected below the mounting box 2, with a placement platform 4 on the base 3; a dispersion mechanism 5 disposed inside the coating pan 1; and a spraying mechanism 6 connected inside the mounting box 2 and connected to a pan cover 7. The dispersion mechanism 5 includes a drive motor 51 connected to the mounting box 2 and connected to a drive shaft 52. The drive shaft 52 is connected to one end of an arc-shaped dispersion rod 54 via a mounting block 53. The arc-shaped dispersion rod 54 is connected to one end of a dispersion straight rod 55, and the other end of the dispersion straight rod 55 is connected to the drive shaft 52. A dispersion inclined rod 56 connects the dispersion straight rod 55 and the arc-shaped dispersion rod 54. An auger 57 is disposed on the drive shaft 52.

[0023] In this embodiment, by controlling the drive motor 51 to work, the drive shaft 52 can be rotated, which in turn drives the arc-shaped dispersing rod 54, the straight dispersing rod 55, and the inclined dispersing rod 56 to rotate, stirring the tablets for uniform coating. The arc-shaped dispersing rod 54, the straight dispersing rod 55, and the inclined dispersing rod 56 can change the coating direction of the tablets, making the tablets uniformly coated. The drive shaft 52 drives the auger 57 to rotate, which can turn the tablets at the bottom of the coating pan 1 upward, so that the tablets at the bottom are coated in place, enhancing the coating effect and improving production efficiency.

[0024] Among them, the arc-shaped dispersing rod 54 disperses the bottom tablets, the dispersing straight rod 55 disperses the top tablets, and the dispersing inclined rod 56 disperses the middle tablets, and supports the arc-shaped dispersing rod 54 and the dispersing straight rod 55.

[0025] like Figure 1 and Figure 3 As shown, specifically, the pot lid 7 is detachably connected to the coating pot 1 by bolts 8. The pot lid 7 is provided with a feeding port 9, and a baffle 10 connected to the pot lid 7 is provided on the outside of the feeding port 9. The bolts 8 facilitate the installation and removal of the pot lid 7 for easy maintenance. The feeding port 9 facilitates the addition of materials. The baffle 10 can also be used to observe the coating effect of the tablets and to seal the feeding port 9 to prevent the tablets from falling out.

[0026] The lid 7 is equipped with a fan and an air outlet. The fan improves the drying process during coating and enhances the coating effect.

[0027] like Figure 1 and Figure 2 As shown, specifically, a discharge pipe 11 is provided below the coating pan 1, and a sealing cover 12 is provided on the discharge pipe 11. A collection box 13 is provided on the placement platform 4. The staff only needs to operate to open the sealing cover 12 to quickly unload the tablets in the coating pan and collect them through the collection box 13.

[0028] Among them, a cover plate adapted to the feed end of the discharge pipe 11 can be provided above the sealing cover 12, so that when the coating pan 1 is working, no part of the tablets will fall into the discharge pipe 11.

[0029] like Figure 2 and Figure 3 As shown, specifically, the spraying mechanism 6 includes a coating agent storage tank 61, which is connected to the mounting box 2. A miniature diaphragm pump 62 is installed on the coating agent storage tank 61. The miniature diaphragm pump 62 is detachably connected to the nozzle assembly 64 via a conduit 63. The nozzle assembly 64 is detachably connected to the pot lid 7. The nozzle assembly 64 includes a spray pipe 65, and multiple atomizing nozzles 66 are arranged circumferentially on the spray pipe 65. By operating the miniature diaphragm pump 62, the coating agent in the coating agent storage tank 61 can be sprayed into the coating pot 1 through the multiple atomizing nozzles 66. The multiple atomizing nozzles 66 arranged circumferentially on the spray pipe 65 can make the coating agent evenly sprayed into the coating pot 1, thereby enhancing the tablet coating effect and accelerating the tablet coating efficiency.

[0030] like Figure 1 and Figure 3 As shown, specifically, the arc-shaped dispersing rod 54 is in close contact with the inner wall of the coating pan 1; by having the arc-shaped dispersing rod 54 in close contact with the inner wall of the coating pan 1, the tablets can also be prevented from adhering to the pan wall.

[0031] like Figure 1 and Figure 2 As shown, specifically, casters 14 are provided below the base 3, and a mounting groove 15 is provided at the bottom of the base 3. An electric lifting rod 16 is connected inside the mounting groove 15, and the lower part of the electric lifting rod 16 is connected to the fixed seat 17. When the electric lifting rod 16 is working, it can drive the fixed seat 17 to rise and fall. When it is necessary to move the device, the fixed seat 17 is raised by controlling the electric lifting rod 16, so that the device can be moved easily by the casters 14. The fixed seat 17 is lowered by controlling the electric lifting rod 16, so that the fixed seat 17 is in close contact with the ground, increasing the friction between the fixed seat 17 and the ground, and facilitating the fixation of the device.

[0032] Working principle: The operator controls the drive motor 51 to drive the drive shaft 52 to rotate, which in turn drives the arc-shaped dispersing rod 54, the straight dispersing rod 55, and the inclined dispersing rod 56 to rotate, stirring the tablets for uniform coating. The arc-shaped dispersing rod 54, the straight dispersing rod 55, and the inclined dispersing rod 56 can change the coating direction of the tablets, ensuring uniform coating. The drive shaft 52 drives the auger 57 to rotate, which can flip the tablets at the bottom of the coating pan 1 upwards, ensuring that the tablets at the bottom are coated in place, enhancing the coating effect and improving production efficiency.
