Description

Technical Field

[0002] In the pharmaceutical industry, capsules are a common drug dosage form with advantages such as good sealing, accurate content, high bioavailability, beautiful appearance and the ability to cover up the bad smell of drugs. The production process of capsules involves multiple links, among which the ingredients are one of the key steps. The quality of the ingredients directly affects the stability and efficacy of the final product.

[0003] Some automated batching devices have appeared on the existing market. For example, the Chinese patent with patent number CN202122547327.9 discloses a mixing device for the production of coenzyme Q10 soft capsules, including a mixing tank and a stirring motor, the stirring motor is installed in the middle of the upper end of the mixing tank, and feeding tubes are provided on both sides of the upper end of the mixing tank. The interior of the mixing tank is provided with an upper cavity, a middle cavity, and a lower cavity from top to bottom. A movable plate is provided directly below the feeding tube, and a weighing sensor is embedded in the upper end of the movable plate. A carrier plate is fixed to the upper end of the movable plate, and the top of the carrier plate is tightly attached to the bottom of the feeding tube; by pouring the raw materials into the feeding tube, the weight of the raw materials can be weighed by using the weighing sensor, and the weighed value will be displayed on the display screen. After adding to the appropriate value, the feeding is stopped, and then the motor is controlled by the button to drive the worm to rotate, so that the movable plate drives the carrier plate to no longer block the bottom of the feeding tube, so that the weighed material can be discharged into the mixing tank, which is more convenient to operate. However, this solution is to weigh the raw materials directly in the feed pipe, which is not convenient for the continuous supply of raw materials and easily leads to insufficient quantitative accuracy of the raw material supply; at the same time, the weighed raw materials in this solution directly enter the mixing tank, and the raw material powder is easily affected by moisture and agglomerates, affecting the subsequent stirring and mixing, resulting in insufficient uniformity of the mixed powder and affecting the effect of the prepared capsules.

[0043] In one embodiment of the present application, a plurality of supporting feet 18 are provided in the area of ​​the mixing drum 1 to facilitate fixing the equipment and ensure the stability of the equipment operation.

[0046] To further optimize the solution, the transmission assembly includes a plurality of give-way grooves 23 opened on the side walls of the processing chamber 21, the give-way grooves 23 are adapted to the movable screen 26, the edges of the movable screen 26 are sealed and slidably connected in the give-way grooves 23, the edges of the movable screen 26 do not separate from the give-way grooves 23, the contact rods 32 extend into the give-way grooves 23 and are arranged in transmission with the movable screen 26; a reset groove 24 is opened at one end of the give-way groove 23 away from the contact rod 32, a reset spring 25 is arranged in the reset groove 24, the reset spring 25 extends out of the reset groove 24 and is fixedly connected to one end of the movable screen 26 away from the contact rod 32.

The coordination of structures such as the weighing tube 41, the weighing block 42 and the discharge hole 43 enables the material to be discharged as needed, thus avoiding waste. When it is necessary to put material into the processing chamber 21, the amount of material required for each feed bin 4 is first input through the control module 110, and then the material is poured into the feed bin 4. The material is then sent into the weighing tube 41 and falls onto the weighing block 42. When the weight of the material falling onto the weighing block 42 reaches the requirement, the entrance of the weighing tube 41 is sealed, and no more material enters. Then, the tube 44 is started to allow the weighed material to fall from the discharge hole 43 into the processing chamber 21.
