Description

Technical Field

[0001] This utility model relates to the field of tablet veterinary drug production technology, and in particular to a tablet veterinary drug coating and drying device. Background Technology

[0002] The tablet veterinary drug coating and drying device is a special equipment used in the veterinary drug production process. It is mainly used for the continuous and automated processing of tablet veterinary drugs for coating and drying and solidification.

[0003] Patent publication number CN212235314U discloses a coating roller and coating machine, including a main body box. A feed pipe is installed inside the feed inlet of the main body box. A dehumidifying heating device and a coating device are installed sequentially from right to left inside the main body box. The feed end of the dehumidifying heating device corresponds to the discharge outlet of the feed pipe. A conveyor plate is fixedly connected to the dehumidifying heating device, and the discharge end of the dehumidifying heating device corresponds to the feed end of the conveyor plate. Although the above patent uses a dehumidifying heating device to dehumidify and dry tablets, allowing for better adhesion between the tablets and the coating agent, this coating machine lacks an internal wall cleaning mechanism. After each batch is discharged or before the end of the production cycle, some coating liquid may adhere to the inner wall of the main body box and the internal surface of the device, which cannot be automatically removed. Long-term use can easily lead to material accumulation, affecting equipment operating efficiency and potentially causing cross-contamination between different batches, thus limiting its application in multi-variety, continuous production.

[0004] Therefore, there is a need for a tablet veterinary drug coating drying device with an automatic cleaning function. Utility Model Content

[0005] To overcome the shortcomings of existing patents that do not have an internal wall cleaning mechanism, where some coating liquid may adhere to the inner wall of the main body box and the internal surface of the device after each batch is discharged or before the end of the production cycle, and cannot be automatically removed, long-term use can easily cause material accumulation, which not only affects the operating efficiency of the equipment, but may also lead to cross-contamination between different batches, thus limiting its application in multi-variety, continuous production, this utility model provides a tablet veterinary drug coating and drying device with an automatic cleaning function.

[0006] The technical solution is as follows: A tablet veterinary drug coating and drying device includes a base, a drying cylinder, an atomizer, a connecting pipe, an air inlet hood, a heat dissipation plate, a stirring mechanism, and a driving mechanism. The drying cylinder is fixedly connected to the base. Multiple atomizers are installed at the top of the drying cylinder, and the multiple atomizers are connected to the connecting pipe. An air inlet hood is fixedly connected to the front of the drying cylinder, and a heat dissipation plate is installed inside the air inlet hood. A stirring mechanism is installed inside the drying cylinder to stir the tablets. A discharge mechanism is installed at the bottom of the drying cylinder. The driving mechanism is used to automatically open or close the drying cylinder. The discharge port at the bottom of the drying cylinder also includes a mounting frame, a screw, a dual-shaft motor, a guide rod, a sliding plate, and a scraper. The mounting frame is fixedly connected to the upper part of the drying cylinder, and the dual-shaft motor is installed at the rear of the drying cylinder. The two output shafts of the dual-shaft motor are connected to the screw via couplings. The end of the screw away from the dual-shaft motor is rotatably connected to the mounting frame. The guide rod is fixedly connected to the front of the mounting frame, and two sliding plates are slidably installed on the guide rod. Sliding plates are also threaded on the screw. The two vertically aligned sliding plates are fixedly connected to the scraper, which contacts the inner wall of the drying cylinder.

[0007] Preferably, the stirring mechanism includes a stirring frame and a servo motor. The stirring frame is rotated inside the drying cylinder, and the servo motor is installed on the left side of the drying cylinder. The output shaft of the servo motor is connected to the stirring frame.

[0008] Preferably, the drive mechanism includes an electric guide rail, an electric slider, and a baffle. Two electric guide rails are installed on both the front and rear sides of the drying cylinder. Electric sliders are installed on the electric guide rails. Two vertically aligned electric sliders are jointly equipped with a baffle, which blocks the discharge port of the drying cylinder.

[0009] Preferably, the device also includes a fixed frame, a feeding cylinder, a feeding rack, a drive motor, and a storage cylinder. The fixed frame is fixedly connected to the top of the drying cylinder, the feeding cylinder is provided at the bottom of the fixed frame, the discharge pipe of the feeding cylinder is connected to the drying cylinder, the feeding rack is rotatably provided inside the feeding cylinder, the drive motor is installed on the left side of the feeding cylinder, and the storage cylinder is provided at the top of the fixed frame, and the storage cylinder is connected to the feeding cylinder.

[0010] As a preferred option, it also includes a limiting plate, with two limiting plates fixedly connected to the base.

[0011] Preferably, a collection box is also included, with the collection box placed in the center of the base.

[0012] Compared with the prior art, this utility model provides a tablet veterinary drug coating and drying device, which has the following beneficial effects: 1. By starting the dual-shaft motor, the dual-shaft motor drives the screw to rotate synchronously. Since one end of the sliding plate is slidably engaged with the guide rod and the other end is threadedly connected to the screw, the rotation of the screw causes the two sliding plates to move left and right synchronously. The scraper then moves back and forth along the inner wall of the drying cylinder, scraping off the material adhering to the inner wall, keeping the drying cylinder clean, avoiding the possibility that some coating liquid may adhere to the inner wall of the drying cylinder, and preventing material accumulation and cross-contamination.

[0013] 2. By starting the servo motor, the stirring rack is driven to rotate continuously inside the drying cylinder to turn and stir the tablets, prevent tablets from piling up, and ensure that each tablet can fully contact the atomized droplets and hot air, thereby improving the uniformity of coating and drying.

[0014] 3. By adjusting the rotation speed of the feeding rack, the feeding rate can be precisely controlled, avoiding material accumulation in the drying drum, thereby improving drying efficiency and processing uniformity. Attached Figure Description

[0022] 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.

[0023] Example 1: A tablet veterinary drug coating and drying device, please refer to [link / reference]. Figures 1-6 The system includes a base 1, a drying cylinder 2, an atomizer 3, a connecting pipe 301, an air inlet hood 4, a heat dissipation plate 5, a stirring mechanism, and a drive mechanism. The drying cylinder 2 is fixedly connected to the base 1. Five atomizers 3 are installed on the top of the drying cylinder 2, and all five atomizers 3 are connected to the connecting pipe 301. An air inlet hood 4 is fixedly connected to the front of the drying cylinder 2, and a heat dissipation plate 5 is installed inside the air inlet hood 4. A stirring mechanism is installed inside the drying cylinder 2 to stir the tablets. The stirring mechanism includes a stirring frame 6 and a servo motor 601. The stirring frame 6 is rotatably installed inside the drying cylinder 2. A servo motor 601 is installed on the left side of the drying cylinder 2, and the output shaft of the servo motor 601 is connected to the stirring frame 6. A discharge mechanism is installed at the bottom of the drying cylinder 2. The drive mechanism is used to automatically open or close the discharge port at the bottom of the drying cylinder 2. The drive mechanism includes an electric guide rail 7, an electric slider 701, and a baffle 8. Two electric guide rails 7 are installed on both the front and rear sides of the drying cylinder 2, and electric sliders 701 are installed on the electric guide rails 7. The two vertically aligned electric sliders... The 701 assembly includes a baffle 8 that blocks the outlet of the drying cylinder 2. It also includes a mounting frame 9, a screw 10, a dual-shaft motor 11, a guide rod 12, a sliding plate 13, and a scraper 14. The mounting frame 9 is fixedly connected to the upper part of the drying cylinder 2. The dual-shaft motor 11 is mounted on the rear side of the drying cylinder 2. Both output shafts of the dual-shaft motor 11 are connected to the screw 10 via couplings. The end of the screw 10 furthest from the dual-shaft motor 11 is rotatably connected to the mounting frame 9. The guide rod 12 is fixedly connected to the front side of the mounting frame 9. The device is equipped with two sliding plates 13, and a sliding plate 13 is also threaded onto the screw 10. The two vertically aligned sliding plates 13 are fixedly connected to a scraper 14, which contacts the inner wall of the drying cylinder 2. Two limiting plates 20 are fixedly connected to the base 1, and a collection box 21 is placed in the middle of the base 1 to collect the dried tablets for easy transfer. The limiting plates 20 contact the side of the collection box 21 to position the collection box 21, prevent it from shifting, and ensure that the material falls into the collection box 21.

[0024] When this device is needed, first connect the coating solution supply system to the connecting pipe 301, and connect the air supply equipment (such as a blower) to the air inlet hood 4. After the tablets enter the drying cylinder 2, the coating solution is delivered by the coating solution supply system to multiple atomizers 3 through the connecting pipe 301. The atomizers 3 atomize the coating solution into fine droplets, which are evenly sprayed onto the surface of the tablets to complete the coating operation. At the same time, the air supply equipment is activated, sending outside air into the air inlet hood 4. The air is heated by the heat dissipation plate 5 inside the air inlet hood 4 to form hot air, which enters the drying cylinder 2 and blows the tablets that have just been sprayed with coating solution, accelerating solvent evaporation and achieving rapid drying. During this process, the servo motor 601 is activated, driving the stirring rack 6 to rotate continuously inside the drying cylinder 2, turning and stirring the tablets to prevent tablet accumulation and ensure that each tablet can fully contact the atomized droplets and hot air, thereby improving the coating and drying process. To ensure uniformity, after the drying process is completed, the electric guide rail 7 is activated, controlling the electric slider 701 to slide synchronously in opposite directions, which in turn drives the connected baffle 8 to slide synchronously in opposite directions, thereby opening the discharge port at the bottom of the drying cylinder 2. Under the assistance of gravity and the stirring rack 6, the tablets are discharged from the discharge port and fall into the collection box 21 below, achieving automatic discharge. After each batch of discharge or before the end of the production cycle, the dual-shaft motor 11 is activated. The dual-shaft motor 11 drives the screws 10 on both sides to rotate synchronously through the coupling. Since one end of the sliding plate 13 is slidably engaged with the guide rod 12 and the other end is threadedly connected to the screw 10, the rotation of the screw 10 causes the two sliding plates 13 to move synchronously left and right. The scraper 14 then moves back and forth along the inner wall of the drying cylinder 2, scraping off the material adhering to the inner wall, keeping the drying cylinder 2 clean, and preventing some coating liquid from adhering to the inner wall of the drying cylinder 2, thus preventing material accumulation and cross-contamination.

[0025] Example 2: Based on Example 1, please refer to... Figure 1 and Figure 5 It also includes a fixed frame 15, a feeding cylinder 16, a feeding rack 17, a drive motor 18, and a storage cylinder 19. The fixed frame 15 is fixedly connected to the top of the drying cylinder 2. The feeding cylinder 16 is provided at the bottom of the fixed frame 15. The discharge pipe of the feeding cylinder 16 is connected to the drying cylinder 2. The feeding rack 17 is rotatably provided inside the feeding cylinder 16. The drive motor 18 is installed on the left side of the feeding cylinder 16. The storage cylinder 19 is provided at the top of the fixed frame 15 and is connected to the feeding cylinder 16.

[0026] When the work begins, the drive motor 18 is started first, which drives the feeding rack 17 inside the feeding cylinder 16 to rotate. Then, the tablet veterinary drugs are put into the storage cylinder 19. The material flows into the feeding cylinder 16 by gravity and is continuously and quantitatively conveyed into the drying cylinder 2 under the action of the rotating feeding rack 17. By adjusting the rotation speed of the feeding rack 17, the feeding rate can be precisely controlled to avoid the accumulation of material in the drying cylinder 2, thereby improving the drying efficiency and processing uniformity.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
