Description

Technical Field

[0001] This utility model relates to the pharmaceutical field, and more particularly to a coating device for pharmaceutical manufacturing. Background Technology

[0002] An existing patent (publication number: CN219090276U) discloses a coating device for pharmaceutical manufacturing. This pharmaceutical coating machine includes a base frame, on which a support mechanism, a stirring mechanism, and a spraying mechanism are mounted. The support mechanism includes an outer cylinder mounted on the upper end of the base frame. A first motor is mounted on the base frame, and the shaft of the first motor is connected to a rotating rod. A support plate is fixedly mounted on the upper end of the rotating rod, and a coating box is mounted on the upper end of the support plate. The stirring mechanism includes a first feed inlet located on the upper end of the outer cylinder. A sealing cover is provided on the first feed inlet, and a fixing block is mounted on the lower end of the sealing cover. A connecting rod is fixedly mounted on the lower end of the fixing block. However, this device has a clause stating that "fixing rods are distributed and installed on the connecting rods." The equipment relies on the fixing rods inside the coating box for pharmaceutical coating stirring. During pharmaceutical coating stirring, because the spraying head is located on the upper part of the coating box, it may be difficult to fully coat and mix the material deposited at the bottom of the coating box, affecting the pharmaceutical coating effect of the equipment. Utility Model Content

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a coating device for pharmaceutical manufacturing. The device utilizes a drive motor at the bottom of the drive frame to drive a gear, which in turn rotates a turning drum inside the frame. Simultaneously, a flap inside the turning drum turns the material, and a nozzle inside the drum sprays slurry. This process causes the turning drum to tumble the material inside, preventing bottom sedimentation and ensuring proper mixing, thereby enhancing the pharmaceutical coating effect.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A coating device for pharmaceutical manufacturing includes a base, a crossbeam, a frame, a drive motor, a secondary wheel, a nozzle, and a tilting roller. The frame is fixedly connected to the crossbeam on one side, and the crossbeam is fixedly connected to a central shaft on one side. The base is adapted to the central shaft and connected to it, allowing the central shaft to rotate within the base. A worm gear holder is fixedly connected to the upper part of the base, adapting to and connecting to a worm gear, allowing the worm gear to rotate within the holder. A worm frame is fixedly connected to the side of the base, and the worm frame is connected to the worm gear. The system is designed with a worm gear carrier connecting to the worm, the worm rotating inside the worm gear carrier, a worm wheel meshing on the upper part of the worm, a fixed connection between the front of the worm gear carrier and the worm motor, a fixed connection between the worm motor output shaft and the worm, a fixed connection between the support roller shaft and the support roller, a frame adapted to the support roller, the frame connected to the support roller, the support roller rotating on the side of the frame, a fixed connection between the rear of the crossbeam and the drive frame, and a drive shaft positioning groove at the lower part of the drive frame, adapted to the drive shaft, the drive shaft connecting to the drive shaft, and the drive shaft rotating inside the drive shaft positioning groove.

[0006] The lower part of the drive frame is fixedly connected to the drive motor, the output shaft of the drive motor is fixedly connected to the drive shaft, and the upper part of the drive frame has a secondary wheel shaft groove, which is adapted to the secondary wheel. The secondary wheel shaft groove is connected to the secondary wheel, and the secondary wheel rotates inside the secondary wheel shaft groove.

[0007] The front part of the drive shaft and the front part of the auxiliary wheel are both fixedly connected to gears. The inside of the drive frame is fixedly connected to the nozzle input connector. The front of the nozzle input connector is fixedly connected to the rotating shaft positioning seat. The inside of the nozzle input connector is connected to the inside of the rotating shaft positioning seat. The front of the rotating shaft positioning seat has a nozzle tube. Beneficial effects

[0008] 1. In the process of using the pharmaceutical coating device of this utility model, after the material is placed inside the turning drum, the drive motor at the bottom of the drive frame drives the gear to rotate, which in turn drives the turning drum inside the frame to rotate. At the same time, the turning plate inside the turning drum turns the material, and the nozzle inside the turning drum sprays slurry, so that the turning drum drives the material inside to tumble, avoiding bottom sedimentation and difficulty in mixing, thereby increasing the pharmaceutical coating effect of the equipment.

[0009] 2. In the process of using the pharmaceutical coating device of this utility model, the drive motor at the rear of the drive frame drives the turning drum to rotate, causing the turning drum to tumble the material inside. In conjunction with the worm motor on the side of the equipment base, the worm drives the worm wheel on the side of the central shaft to rotate. Thus, during the stirring process, the material inside the turning drum is tumbled back and forth through the central shaft, avoiding a relatively fixed material trajectory, thereby increasing the pharmaceutical coating efficiency of the equipment.

[0010] 3. During the use of the pharmaceutical coating device of this utility model, the rotating roller is driven by the drive motor at the rear of the drive frame, and the two sets of frames inside the crossbeam work together to position the rotating roller, so as to avoid gear jamming caused by unilateral force on the rotating roller, thereby increasing the stability of the equipment.
