Description

Technical Field

[0001] The invention relates to the technical field of medical capsule production, in particular to a medicine powder filling device for capsule production. Background Art

[0002] Drugs packed in capsules are usually powders or granules that are irritating to the esophagus and gastric mucosa, or have a bad taste, are easy to volatilize, are easily decomposed by saliva in the mouth, or are easily inhaled into the trachea. Putting these drugs into capsules not only protects the drug properties from being destroyed, but also protects the digestive organs and respiratory tract. Removing the capsule shell may cause drug loss, drug waste, and reduced efficacy. In addition, some drugs need to be dissolved and absorbed in the intestines, and capsules are a kind of protection to protect the drugs from being destroyed by gastric acid. The existing devices still have defects when producing capsules. The structure of the existing devices is relatively complex, and energy loss will occur when the equipment is operating. Even if filled by intelligent machines, a small amount of weight shortage will occur, which will lead to the appearance of defective capsules and affect the overall production quality. Therefore, it is urgent to develop and design a capsule powder filling machine with a sophisticated structure and a high degree of automation. Summary of the invention

The control member can control the filling operation in an orderly manner, and can achieve safe, orderly, qualified and standardized filling operations.

[0021] like Figure 1 , 5 As shown, an assembly plate 701 is provided on one side of the receiving plate 7, and the assembly plate 701 is fixedly connected to the side wall of the supporting plate 2 through a threaded rod, and a receiving tube 703 is provided in the middle of the receiving plate 7, and a bell mouth 702 is provided at the top of the receiving tube 703, and the bell mouth 702 and the receiving tube 703 constitute a receiving space for storing capsules to be filled, and the capsules to be filled are placed one by one into the receiving space constituted by the bell mouth 702 and the receiving tube 703 for storing the capsules to be filled, and the bell mouths 702 at the top of a row of receiving plates 7 will receive the medicine powder and enter the capsules to be filled.

[0022] like Figure 1 , 4As shown, the linear propulsion assembly includes two planar shaft seats 501 on the side wall of the frame 1, and positioning rollers 502 are rotatably installed on one side of the two planar shaft seats 501. The positioning rollers 502 are connected by a carrying belt 5. The positioning roller 502 at the left end is installed on the output end of the stepper motor 503. The carrying belt 5 and the top surface of the carrying plate 2 are connected by a connecting bridge 504. The stepper motor 503 drives the carrying belt 5 to run a short distance through the positioning roller 502, and then the carrying plate 2 moves together with the carrying belt 5 through the connecting bridge 504. The two rows of accommodating plates 7 can be rotated to arrive at the work, and the row of accommodating plates 7 that is not at the work station can disassemble the capsules to be filled, saving operation time.

[0023] like Figure 1 , 2 As shown in , 4, the feeding mechanism includes a power pump 6 on the side wall of the frame 1, and a towing hose 601 is provided at the output end of the power pump 6.

Each inner wall of the accommodating cylinder 703 is provided with a scale. When the medicine powder is filled to a specified amount, timely feedback is given to the control part to stop the filling operation. The program controls the filling accurately, efficiently and without error, so the filling efficiency can be greatly improved.

[0026] like Figure 1 , 5 As shown, the auxiliary parts also include a micro vibration motor. A micro vibration motor is installed in each accommodating tube 703. When the powder in the capsule is filled, the vibration of the motor can make the powder flat, which is convenient for subsequent operations.

[0027] like Figure 1 , 5 As shown, the metering scale, power pump 6 and micro vibration motor are all electrically connected to the control component, and the cooperation between the four enables the entire device to achieve efficient and error-free operation.

[0028] Working principle: After the left row is filled, the carrier plate 2 will move back and forth in the frame 1 for a short distance, and the holding plates 7 on the left and right rows of the carrier plate 2 can take turns to reach the material receiving station below the powder supply tube 402, and the vertical rod 201 at the top of the carrier plate 2 will provoke the notch frame 401, and then the loading platform 4 and the powder supply tube 402 at its bottom will be pushed a short distance in the longitudinal direction, and the powder supply tube 402 will be aligned with the other row of holding plates 7 for filling operations.
