Eyedrops are one of the most commonly used drug dosage forms for eye diseases, and for many eye diseases, eye drops have a direct and quick therapeutic effect. As people's lifestyles and working conditions change, they spend more and more time using their eyes, such as looking at computers, playing cell phones, watching TV, playing video games and so on for long periods of time, and are prone to visual fatigue and dry eyes.

These two diseases are mainly manifested by dry eyes, so many people turn eye drops into a daily "essential medicine". In fact, eye drops, in principle, are not necessary to be used routinely.

With BOTTLINGLIFE special customized test kit filling capping machine .we can improve your production

Eye drops filling machine is suitable for pharmaceutical, chemical, food, light industry and other industries for glass, plastic, metal and other containers with vacuum negative pressure, self-priming filling equipment, the machine is used to be filled container caliber should be small, the caliber of the liquid surface up spreading stress should be greater than the liquid static pressure. Such as oral liquid plastic bottles. The wind oil essence bottle, eye drops bottle, cosmetic perfume bottle, battery liquid filling and so on.

The working principle of eye drops filling machine is.

(1) Transmission principle: The motor transmits the power to the worm wheel shaft of the reducer through the belt pulley, and then the worm wheel shaft transmits the power to the paddle wheel shaft and the filling part and the cap rolling head through each gear. The filling part, capping head and each paddle wheel move synchronously and transmit the power to the bottle feeding paddle wheel device through the bevel gear.

(2) Principle of filling part: The eye drops bottle is sent to the transition paddle wheel by the big bottle inlet paddle wheel, and then sent to the synchronous belt by the transition paddle wheel, and the bottle is dragged forward at a uniform speed by the inlay on the synchronous belt, and the filling needle is inserted into the bottle mouth under the control of the tracking mechanism, and runs forward synchronously with the bottle to realize tracking and filling. The diving needle rises with the liquid level to play the role of defoaming.

(3) Cap supply system: It is composed of cap delivery track, cap management head and cap-wearing mechanism. The lid management head adopts the principle of electromagnetic spiral oscillation to line up the messy lids and enter the lid delivery track through the reversing twist channel, and when passing through the lid-wearing mechanism, the bottle hangs on the lid and passes through the pressing plate to make the lid wear correctly.

(4)Spinning cap head: After the eye drop bottle wears the cap and enters the spinning cap head turntable, the cap is pressed under the control of the cam while the cylinder holds the bottle and the bottle does not move, at which time the spinning cap head tightens the cap and leaves the cap at the same time and returns to the original position.

• Tracking filling mechanism: The servo motor drives the gear and rack movement, which drives the filling needle to do reciprocating movement. By adjusting the relative position of the spray needle holder and the mounting frame, the filling needle can be accurately inserted into the middle of the bottle mouth.
• Simple structure, reliable and less failure.
• Adopting cone piston, with good sealing performance, accurate dispensing liquid volume and convenient liquid volume adjustment.
• The liquid touching part is made of stainless steel, and it is easy to load and unload, and can be aseptically dispensed.
• The cylinder, push rod and piston are made of stainless steel, which is corrosion and wear resistant.
• The speed is continuously adjustable, easy to operate.
