Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0016] Such as figure 1 , The dripper device includes a machine base 9 on which an outer cylinder 6 is installed, and the outer cylinder 6 is provided with an oil inlet 16 and an oil outlet 20 . An inner cylinder 18 is arranged in the outer cylinder 6, and a valve 17 is installed in the inner cylinder 18. The valve 17 is connected to the cylinder 7 through a pneumatic actuator, and the lower end of the valve 17 is also connected with a sealing ring 15. The lower end of the inner cylinder 18 is connected to the base 9, and the upper end is connected to the cylinder body 4 which is also located inside the outer cylinder 6. The upper end of the cylinder body 4 is connected to the bracket 2. The upper end surface of the cylinder body 4 is on the same plane as the upper end surface of the outer cylinder 6. The cylinder body 4 has a drug feeding tub...

The invention relates to a stepping, pressure boosting and air ejecting droplet pill dropper. A machine seat is provided with an outer cylinder; the outer cylinder is provided with an inner cylinder inside, and the inner cylinder is provided with a valve inside; the lower end of the inner cylinder is connected with the machine seat; a tank body with a medicine inlet pipe is provided with a piston inside, and a piston rod is in transmission connection with a stepping motor; a cavity body of the machine seat is provided with a dropper disk with dropper nozzles inside; a fan cover is provided with a plurality of stream guiding holes of which the positions correspond to the dropper nozzles; the lower ends of the dropper nozzles pass through from the stream guiding holes, and even stream guiding gaps are reserved between the outer walls of the dropper nozzles and the inner walls of the stream guiding holes; a cavity side wall enclosed by the dropper disk, the machine seat and the fan cover is provided with a plurality of air inlet holes; the machine seat is also provided with an annular air cavity inside, and the annular air cavity is communicated with the air inlet holes; and the lower end of an air inlet pipe is communicated with the annular air cavity. The stepping motor drives the piston to pressurize medicine liquid rhythmically, and the medicine liquid flows out through the thin dropper nozzles, and then is input with air through pressure air pulse to blows off droplet pills. The droplet pill dropper is applicable to dropping the droplet pills with the diameter between 0.5 and 1.5 mg and the pill weight between 1 and 3 mg.
Description
technical field [0001] The invention relates to a novel dripper device for pill making, in particular to a step-pressurized air flushing micro-droplet pill dripper. It is mainly suitable for dripping pills with a diameter of 0.5-1.5mg and a pill weight of 1-3mg. Background technique [0002] The existing drop pill machine can only drip drop pills above 6 mg due to the tension effect of the medicinal liquid under the condition of self-weight dripping, and cannot drop micro-drop pills below 6 mg at all, which limits the development of new drug dosage forms. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned existing products, and provide a step-pressurized air-impact micro-pill dripper, which can realize the dripping of micro-pills through step-by-step pressurization and pulse blowing. [0004] In order to solve the above technical problems, the present invention adopts the fo...
