[0015] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0016] Depend on Figures 1 to 6 It is known that a tablet film coating device includes a main body 1, a coating cavity 2 inside the main body 1, the center line of the coating cavity 2 forming an angle with the horizontal plane, the main body 1 is provided with a feeding port 3 and a discharging port 4 located at the bottom and top of the coating cavity 2 respectively, a placement plate 5 can be taken into the coating cavity 2 from the feeding port 3 and the discharging port 4, the placement plate 5 is provided with multiple placement cavities 6, the placement cavities 6 are provided with filter screens 7 on both sides, the placement cavities 6 are provided with an opening 8 on one side, tablets are placed into the placement cavities 6, the upper sides of the coating cavity 2 are provided with drive shafts 9 for driving the placement plate 5 to move, and the main body 1 is provided with drying fans 10 located on the upper part of the coating cavity 2.

[0017] In practical use, this utility model Place the coating slurry into the coating chamber 2, place the tablets to be coated into the storage chamber 6 of the storage plate 5, and then place the storage plate 5 into the coating chamber 2 from the feeding port 3. Start the equipment, and the drive shaft 9 will drive the storage plate 5 to move upward in the coating chamber 2. During the movement, the tablets are coated. After the storage plate 5 is removed from the coating slurry, the drying fan 10 dries the tablets. Finally, the storage plate 5 is removed from the discharge port 4, the coated tablets are removed, and new tablets are filled in.

[0018] Throughout the process, the equipment does not need to be stopped and can run continuously, which indirectly improves production efficiency.

[0019] The angle between the centerline of the coating chamber 2 and the horizontal plane is 20±5°. This ensures the height of the coating slurry, allowing the tablets to be fully coated, and also leaves some space in the upper part of the coating chamber 2 to dry the tablets.

[0020] The main body 1 has limiting grooves 11 on both sides of the coating cavity 2. The top of the shelf 5 has limiting plates 12 that cooperate with the limiting grooves 11. The drive shaft 9 is located at the bottom of the limiting groove 11. The drive shaft 9 has a spiral groove 13. The bottom of the limiting plate 12 has an arc-shaped groove 14 that cooperates with the drive shaft 9. The positioning rod 15 that is inserted into the spiral groove 13 extends from the arc-shaped groove 14. The main body 1 is equipped with a drive motor that connects to the drive shaft 9. The two drive shafts 9 rotate synchronously.

[0021] The drive motor drives the two drive shafts 9 to rotate synchronously. The rotation of the spiral groove 13 pushes the positioning rod 15 to move laterally within the spiral groove 13. That is, the placement plate 5 moves upward along the axis of the drive shaft 9. During the movement, the limiting plate 12 is located within the limiting groove 11, so that the relative position of the placement plate 5 and the drive shaft 9 remains stable, ensuring the rise of the placement plate 5. When it reaches the unloading port 4, the placement plate 5 can be taken out.

[0022] To prevent damage to the shelf 5 due to failure to remove it in time, the end of the spiral groove 13 is set to be annular at the discharge port 4, so that the shelf 5 can be stably held at the discharge port 4 and will not continue to move forward and collide with the main body 1. However, the shelf 5 must be removed before the next shelf 5 arrives. Therefore, an alarm mechanism needs to be added here. The alarm will sound after the shelf 5 stays for a certain period of time to remind the staff to remove the shelf 5.

[0023] Compared with the prior art, this utility model has the following advantages: by modifying the coating process to make a certain angle with the horizontal plane, the entire process is completed with one end in and one end out without affecting each other. Therefore, the entire process can be completed without stopping the machine, which can improve production efficiency.
