What are the working principles and components of the oral liquid filling machine?

The oral liquid filling machine is mainly used for filling small doses of tincture water, syrup, etc. in pharmaceutical factories. It is one of the main components of the oral liquid washing, drying, filling and rolling unit. It can be connected online or used as a stand-alone machine. The oral liquid filling machine mainly has the following operating principles and components.

(1) Transmission principle: The motor transmits the power to the reducer worm gear shaft through the pulley, and then the worm gear shaft passes through each gear to transmit the power to the dial shaft, filling part and capping head. The filling part, capping head and each dial wheel move synchronously, and the power is transmitted to the bottle feeding dial equipment through the bevel gear.

(2) Principle of the filling part: Oral liquid bottles are sent from the bottle feeding wheel to the transition wheel, and then sent to the synchronous belt by the transition wheel. The insert on the synchronous belt drags the bottle forward at a constant speed, and the filling Under the control of the tracking mechanism, the needle is inserted into the mouth of the bottle and moves forward synchronously with the bottle to achieve tracking filling. The submersible needle rises as the liquid level rises, playing a defoaming role.

(3) Cap supply system: It consists of cap feeding track, cap management head and cap wearing mechanism. The cap sorting head adopts the principle of electromagnetic spiral oscillation to sort the messy caps into a queue and enter the cap transport track through the reversing twist channel. When passing through the cap-wearing mechanism, the caps hanging from the bottles pass through the capping plate to ensure that the caps are properly worn.

(4) Capping head: After the oral liquid bottle puts on the cap and enters the capping head turntable, the three opened knives will rotate forward with the bottle as the center, and press the cap under the control of the cam. At this time, the three capping knives will Under the action of the taper sleeve, the rolling knife is rolled toward the cover at the same time. After rolling, it is separated from the cover at the same time and returns to its original position.

(5) Tracking the filling mechanism: The oral liquid filling machine uses a servo motor to drive the gears and racks, and then drives the filling needle to reciprocate. By adjusting the relative position of the spray needle frame and the mounting frame, the filling needle can be accurately inserted into the middle of the bottle mouth.
