The invention discloses an ultra-micro accurate filling device which is characterized by comprising a powder hopper for containing powder, wherein the bottom of the powder hopper is provided with a sieve, a vibration platform for fixing the powder hopper, a vibrator for enabling the vibration platform to vibrate, a lifting screw rod for enabling the vibration platform to generate vertical displacement, a motor for driving the lifting screw rod, a bottle holder for supporting a bottle, a weighing head for fixing the bottle and a weight sensor for vibrating the weight of the powder in the bottle by a real-time vibrator 8. The invention can realize ultra-micro accurate filling, and the precision can reach 0.1 mg.
Description
Technical Field
The invention relates to a method for carrying out ultra-micro accurate filling on medicinal powder or other powder, belonging to the technical field of mechanical equipment.
Background
The minimum loading of the powder is usually more than 0.1 g by the current mechanical equipment. The technical bottleneck of pharmaceutical equipment is to divide the milligram-level packaging amount and to achieve accurate packaging (for example, 2 milligrams). The existing mechanical equipment is difficult to achieve corresponding accuracy.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: provides a device capable of carrying out ultra-micro accurate filling on medicinal powder or other powder.
In order to solve the above technical problems, an aspect of the present invention is to provide an ultra-micro precise filling apparatus, including:
the powder hopper is used for containing powder, and the bottom of the powder hopper is provided with a sieve;
the vibrating platform is used for fixing the powder hopper;
a vibrator for generating vibration to the vibration platform;
the lifting screw rod is used for enabling the vibration platform to generate vertical displacement;
a motor for driving the lifting screw;
a bottle holder for holding a bottle;
a weighing head for holding the bottle;
and the weight sensor is used for monitoring the weight of the powder in the vibrating bottle in real time.
Preferably, the weight sensor is fixed on the bottom frame, the lifting screw rod is fixed on the back plate, the back plate is fixedly connected with the workbench, and the weight sensor or the bottom frame is arranged in the workbench in a penetrating mode. In order to weigh without being affected by the vibrations of the worktable, the weight sensor is fixed on the underframe and does not directly contact with the worktable.
Preferably, the measurement accuracy of the weight sensor is 0.1 mg.
Preferably, the vibrator drives the vibration platform to vibrate, powder in the powder hopper is vibrated to fall into the bottle in a powder fog shape through the sieve, the weight sensor monitors in real time, when a set value is reached, a signal is sent to the vibrator, the vibrator stops vibrating, and the vibration platform and the powder hopper are driven by the motor to move up and down along with the lifting screw rod to finish ultra-micro accurate filling.
The invention can realize ultra-micro accurate filling, and the precision can reach 0.1 mg.
