[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please refer to the accompanying diagrams in all instruction manuals:

[0023] A coating device for sugar coating of bisacodyl enteric tablets includes a base 1 and a coating pan 2. A frame 3 is fixedly installed on the base 1. A control button 4 is provided outside the frame 3. A blower 5 is provided inside the frame 3. An air duct 6 is fixedly installed on the frame 3. The air duct 6 is connected to the blower 5. A flip-adjustable safety component is provided between the base 1, the frame 3 and the coating pan 2.

[0024] The adjustable safety component includes a safety mechanism between the base 1 and the coating pan 2 and a groove 7 located in the frame 3. A motor 8 is fixedly installed in the groove 7. A worm gear 9 is fixedly installed on the output end of the motor 8. A rotating shaft 10 is fixedly installed in the groove 7. A support rod 11 is rotatably connected to the rotating shaft 10. A worm wheel 12 is fixedly installed on the support rod 11. The worm gear 9 and the worm wheel 12 mesh with each other. A second motor 13 is fixedly installed on the support rod 11. The output end of the second motor 13 is fixedly connected to the coating pan 2. A metal flexible hose 14 is provided on the air outlet of the air duct 6. The control button 4 is electrically connected to the first motor 8 and the second motor 13.

[0025] As described above, by controlling button 4, the operation of motor 8 and blower 5 can be controlled, which drives worm gear 9 to rotate, drives worm wheel 12 to rotate, drives support rod 11 to rotate, and drives coating pan 2 to rotate, realizing the conversion between the corresponding feeding position and working position; the worker can control metal hose 14, which can be adjusted to any shape and position. When feeding, metal hose 14 can be moved out of coating pan 2, and before rotating the coating pan, metal hose 14 can be inserted into coating pan 2. The operation is convenient, efficient and fast.

[0026] As a technical optimization of this utility model, the safety mechanism includes a support base 15 fixedly installed on the base 1. The support base 15 has an arc-shaped through hole 16 corresponding to the coating pot 2. A connecting shaft 17 is slidably connected in the arc-shaped through hole 16. Connecting rods 18 are rotatably connected to both ends of the connecting shaft 17. A tray 19 is fixedly installed on the connecting rod 18 corresponding to the coating pot 2. The tray 19 is slidably connected to the coating pot 2. A second groove 20 is symmetrically provided in the arc-shaped through hole 16. A spring 21 is symmetrically fixedly installed in the second groove 20. A telescopic rod 22 is fixedly installed on the spring 21. The telescopic rod 22 is slidably connected to the second groove 20. A pin 23 is fixedly installed on the connecting shaft 17 corresponding to the second groove 20.

[0027] As described above, the tray 19 can move with the coating pan 2. When the coating pan 2 rotates around the pivot, it will move the tray 19, which in turn moves the connecting rod 18 and the connecting shaft 17 on the arc-shaped through hole 16. The springs 21 and telescopic rods 22 at the two ends of the arc-shaped through hole 16 represent the two extreme positions of the coating pan 2 when it is rotated. The upper position represents the position when the coating work is in progress, and the lower position represents the position for feeding materials before the coating work begins. The connection between the pin 23 and the telescopic rod 22 ensures that the coating pan 2 has a relatively stable extreme environment, guaranteeing the normal operation of feeding or rotating materials and improving the stability of practical use.

[0028] As a technical optimization of this utility model, heating devices 24 are provided on both the air duct 6 and the tray 19, and the heating devices 24 are electrically connected to the control button 4.

[0029] As can be seen from the above description, the heating device 24 contains several heating wires. After being heated by the heating wires, the heat is conducted to the air duct 6 or the tray 19 to heat the airflow in the air duct 6 and the coating pan 2. This can make the sugar coating layer uniform in thickness, avoid the coated sheets from being too wet, and improve the coating efficiency.

[0030] As a technical optimization of this utility model, a ball bearing 25 is rotatably connected to the telescopic rod 22;

[0031] As can be seen from the above description, the ball bearing 25 can reduce the wear between the telescopic rod 22 and the pin 23, while not affecting the fixation between the pin 23 and the telescopic rod 22.

[0032] As a technical optimization of this utility model, the arc-shaped through hole 16 coincides with the rotation center of the rotating shaft 10;

[0033] As can be seen from the above description, the coincidence of the centers of rotation makes the protection of the tray 19 more effective when the coating pan 2 is rotating.

[0034] As a technical optimization of this utility model, a plurality of auxiliary rods 26 are uniformly fixedly installed on the support rod 11, and the other end of the auxiliary rods 26 is fixedly connected to the coating pan 2.

[0035] As can be seen from the above description, the auxiliary rod 26 can reduce the pressure on the motor 13, making the overall rigidity stronger and the overall stability better.

[0036] The working process of this utility model is as follows:

[0037] By controlling button 4, motor 8 is activated, driving worm gear 9 and worm wheel 12 to rotate, causing coating pan 2 to flip to the bottom feeding position, pouring the raw sheets into coating pan 2. Then, motor 8 is activated, causing coating pan 2 to flip upwards and enter the working position. Motor 20, blower 5, and heating device 24 are activated, and a certain amount of sugar coating liquid is poured in. Under the action of air heat and heating of the coating pan, the sugar coating layer thickness is made uniform, avoiding the coated sheets from being too wet and improving coating efficiency. During the upward and downward flipping of the coating pan, connecting shaft 17 moves in the arc-shaped through hole 16, and is connected and fixed in a snap-fit ​​state with springs 21 and telescopic rods 22 on both sides through pin 23, making the position of coating pan 2 more stable, extending the overall life and ensuring the effective operation of coating.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
