AI Technical Summary
In existing technologies, it is difficult to effectively separate the capsule cap from the capsule mold, resulting in processing difficulties.
A capsule pre-rolling and loosening device was designed. The gear and rack mechanism driven by a motor makes the rack move left and right in the track, which drives the rotating sleeve to rotate, thereby rolling the capsule cap body sleeved on the mold needle to separate it from the mold.
This effectively prevents the capsule cap from sticking to the mold, ensuring that the capsule can be easily detached from the mold and improving production efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of capsule production tooling, and in particular to a capsule pre-rolling and loosening device. Background Technology
[0002] The main function of the capsule shell is to protect the drug from the influence of external environment such as humidity, oxygen, and light, thereby improving the drug's stability and shelf life; and to control the drug release rate and method. For example, enteric-coated capsule shells can prevent the drug from being destroyed or released prematurely in the stomach.
[0003] After the capsule cap is placed on the capsule mold, in order to prevent the capsule cap from sticking to the capsule mold, it is necessary to control the capsule cap to rotate, so that the inner surface of the capsule cap and the surface of the capsule mold are relatively displaced, so as to facilitate the subsequent processing of the capsule cap. Utility Model Content

[0006] By adopting the above technical solution, the motor drives the first rotating shaft to rotate, which in turn drives the first rotating sleeve to rotate. At the same time, it also drives the first gear to rotate, thereby controlling the rack to move left and right within the track. When the rack moves left and right, it can drive the second gear to rotate, which in turn drives the second rotating sleeve to rotate. Through the rotation of the first rotating sleeve and the second rotating sleeve, the capsule cap body sleeved on the mold needle can be rubbed, so that the capsule mold can be smoothly detached from the mold.
[0007] As a further description of the above technical solution:
[0008] A first bearing is mounted on the outer surface of the first shaft, and the first bearing is installed inside the mounting bracket.
[0009] By adopting the above technical solution, it is convenient for the first rotating shaft to rotate inside the mounting bracket.
[0010] As a further description of the above technical solution:
[0011] A second bearing is mounted on the outer surface of the second shaft, and the second bearing is installed inside the mounting bracket.
[0012] By adopting the above technical solution, it is convenient for the second rotating shaft to rotate inside the mounting bracket.
[0013] As a further description of the above technical solution:
[0014] The top of the frame is equipped with a slide rail, and the movable frame is mounted on the slide rail.
[0015] By adopting the above technical solution, the movable frame can move on the machine frame, thereby adjusting the position of the first rotating sleeve and the second rotating sleeve, which facilitates the rubbing of the capsule cap body.
[0016] As a further description of the above technical solution:
[0017] A fixing frame is fixedly connected to the top of the frame, and a fixing groove is provided on the side wall of the fixing frame.
[0018] By adopting the above technical solution, it is easy to install the mold on the fixed frame.
[0019] As a further description of the above technical solution:
[0020] A mold is movably connected inside the fixed groove, and mold pins are fixedly connected to the outer surface of the mold. There are multiple mold pins, and the position of the mold corresponds to the position of the first rotating sleeve.
[0021] By adopting the above technical solution, during production, the capsule cap will be fitted onto the mold needle for transfer and processing operations. The position of the mold corresponds to the position of the first rotating sleeve, which facilitates the rubbing of the capsule cap on the mold needle.
[0022] This utility model has the following beneficial effects:
[0023] Compared with the prior art, this capsule pre-rolling and loosening device uses a motor to drive the first rotating shaft to rotate, which in turn drives the first rotating sleeve to rotate. At the same time, it also drives the first gear to rotate, thereby controlling the rack to move left and right within the track. When the rack moves left and right, it can drive the second gear to rotate, which in turn drives the second rotating sleeve to rotate. Through the rotation of the first rotating sleeve and the second rotating sleeve, the capsule cap body fitted on the mold needle can be rolled, preventing the capsule cap body from sticking to the capsule mold and facilitating the smooth detachment of the capsule from the mold.

The mounting bracket 3 has a fixed track 8 at its inner bottom. A rack 9 is movably connected inside the track 8. The rack 9 can move within the track 8. The top of the rack 9 meshes with the side of the first gear 6 and the side of the second gear 11. The rotation of the first gear 6 drives the rack 9 to move, which in turn drives the second gear 11 to rotate. The motor 4 drives the first rotating shaft 5 to rotate, which in turn drives the first rotating sleeve 7 to rotate. At the same time, it also drives the first gear 6 to rotate, thereby controlling the rack 9 to move left and right within the track 8. When the rack 8 moves left and right, it can drive the second gear 11 to rotate, which in turn drives the second rotating sleeve 12 to rotate. Through the rotation of the first rotating sleeve 7 and the second rotating sleeve 12, the capsule cap body fitted on the mold needle of the mold 15 can be rubbed, so that the capsule mold can be smoothly detached from the mold 15.
[0033] A first bearing is installed on the outer surface of the first rotating shaft 5. The first bearing is installed inside the mounting frame 3 to facilitate the rotation of the first rotating shaft 5 inside the mounting frame 3. A second bearing is installed on the outer surface of the second rotating shaft 10. The second bearing is installed inside the mounting frame 3 to facilitate the rotation of the second rotating shaft 10 inside the mounting frame 3.
[0034] A slide rail is installed on the top of the frame 1, and a movable frame 2 is installed on the slide rail, so that the movable frame 2 can move on the frame 1 to adjust the position of the first rotating sleeve 7 and the second rotating sleeve 12, which facilitates the rubbing of the capsule cap.
[0035] A fixed frame 13 is fixedly connected to the top of the frame 1. A fixed groove 14 is provided on the side wall of the fixed frame 13. A mold 15 is movably connected inside the fixed groove 14. A mold pin is fixedly connected to the outer surface of the mold 15. There are multiple mold pins. The position of the mold 15 corresponds to the position of the first rotating sleeve 7. During production, the capsule cap will be placed on the mold pin of the mold 15 for transfer and processing operations. The position of the mold 15 corresponding to the position of the first rotating sleeve 7 facilitates the rubbing of the capsule cap on the mold pin.
[0036] Working principle: When in use, the motor 4 drives the first rotating shaft 5 to rotate, which in turn drives the first rotating sleeve 7 to rotate. At the same time, it also drives the first gear 6 to rotate, thereby controlling the rack 9 to move left and right within the track 8. When the rack 8 moves left and right, it can drive the second gear 11 to rotate, which in turn drives the second rotating sleeve 12 to rotate. Through the rotation of the first rotating sleeve 7 and the second rotating sleeve 12, the capsule cap body fitted on the mold needle of the mold 15 can be rubbed to prevent the capsule cap body from sticking to the capsule mold 15, so that the capsule mold can be easily detached from the mold 15.
