IV Solution Filling Machine

SIV blow molding machine is great equipment for producing BOPP IV bottle.

The main production flow of this equipment is as below:

(1)sending pre-cool preform onto carriers by conveying system

(2) heating preform with heater

(3) sending preform into molding cavity by mechanical clamp

(4)two-step stretching and blow molding preform inside mold

(5)taking out finished bottle

(6) automatic connection device to filling machine .Adopted smart high-accurate auto voltage control system the equipment can accurately control preform temperature and greatly save manpower, raw material and energy.

Preform molding uses servo preform loading system, pneumatic mold clamp system, unique rotary convey system, preform loading system and two-step servo stretch molding system which can accurately control stroke and guarantee even bottle thickness. Besides, the equipment uses user friendly interface and has tele-diagnosis system to ensure safer and more reliable running.

The qualified plastic bottle that has been blown out by the blow molding machine is transported to the robot on the bottle washing part by a pneumatic (or conveyor belt) conveying device. After the robot grips the bottle neck, the plastic bottle is turned 180°to make the bottle mouth face down for washing.

Each of the bottle washing needles of the air washing device is provided with a separate negative ion generating device, the needle is inserted into the bottle under the guidance of the rising cam and the bottle mouth is sealed, the clean compressed air of the ionizing air gun is ionized, and the electrode tip is placed. Positive ions are generated, negative ions are generated at the tip of the negative electrode, and positive and negative ions are simultaneously generated to neutralize the surface of the object. When the surface of the charged object is positive, the negative ions will neutralize. Conversely, if the surface is negative, the positive ions will neutralize.

It is blown into the bottle by the ion air gun to eliminate the static electricity in the bottle. At the same time, the plastic particles and other debris that have been eliminated from the bottle are blown to float in the space inside the bottle, and the vacuum is arranged at the bottom of the needle. The device draws particles and debris suspended in the space into a sealed pipe and discharges it outdoors.

Since the needle is inserted into the bottle, it keeps track of the synchronous movement of the plastic bottle until it leaves the plastic bottle, ensuring that the plastic bottle has sufficient cleaning time. After the needle leaves the bottle, the robot then flips the plastic bottle 180°so that the bottle mouth is facing up and transported to the filling site.

The bottle washing station has real-time display of voltage orcurrent of the ion gun, and has online detection and alarm functions. An ion wind external washing device is arranged at the bottle opening and discharging position of the bottle turning track, and the ion wind main pipe is arranged into a curved air outlet to be aligned with the outer wall of the bottle for ion wind blowing, and is suspended by a vacuum vent hole on the machine table. The substance is drawn into the sealed pipe and discharged to the outside.

The air-washed plastic bottle is transferred from the robot to the filling part, and the filling part is filled with the plastic bottle to carry out the filling. A constant pressure liquid balance tank is arranged on the upper part of the filling part.

The liquid medicine pipe from the thin tank of the workshop is composed of an inlet pipe and a return pipe. The inlet pipe flows into the tank through the pneumatic valve at the top of the constant pressure balance tank. When the liquid in the balance tank is filled and reaches the set liquid level, the inlet pneumatic valve is closed, and the liquid is returned to the rare tank through the return line. Inside. When the pressure in the constant pressure balance tank is lower than the set liquid pressure value, the control device will issue a pneumatic valve to the upper part of the tank to automatically open it, and keep the pressure (liquid level) in the constant pressure tank constant, thus ensuring The filling process works effectively.

The filling metering is controlled by the opening time of the upper filling pneumatic valve (Gaimi) of each filling head. The opening time of each filling pneumatic valve can be set separately. The pressure is constant, the filling time is constant, and the metering control is consistent. When there is a bottle in the lower part of the filling head, the filling pneumatic valve is opened, and the metering filling is performed by time control. When the bottle is not in the lower part of the fillinghead, the filling pneumatic valve installed on the upper part of the nozzle is closed, and the liquid medicine is cut off to realize the function of no bottle filling.

The filling group consists of a plurality of pneumatic diaphragm valves, and a single control is performed. On the touch screen screen, the filling time of each pneumatic diaphragm valve can be separately set, thereby ensuring the accuracy and consistency of the loading. At the same time, it can store and fill the program of different specifications in the PLC, and directly call out the replaceable specifications, which is convenient to operate.

There is no mechanical friction in the filling process, no particles are generated, and the filling time is convenient and quick to adjust. The touch screen can be adjusted, and the adjustment precision can be up to 1/100 second to ensure accurate measurement. After the filling is completed, the filling system is fully sealed by pipe connection, and in-place cleaning (CIP) and in-position disinfection (SIP) are realized.

This part is mainly used for the sealing of the infusion bottle after the filling of the liquid in the plastic bottle infusion production process, and the double-layer heating plate is used for the non-contact hot-melt welding cap sealing. After the medicine is poured, the bottle enters the bottle neck through the bottle discharging mechanism, the delivery part, and the welding cap feeding mechanism, and the bottle cap is clamped by the handle cover and supplied to the cover rail.

When the bottle opening mechanism photo electrically opens the sensor bottle, the end cap of the cover rail is pushed out, the cap enters the capping mechanism forward, the cap plate dials out the cap, and when running to the junction, the manipulator moves down the cam curve Bottle cap. At the same time as the cap cylinder is pushed out, the propulsion cylinder of the heating mechanism is pushed out.

When the heating reaches the welding cap requirement (the cap sealing surface and the bottle end face are simultaneously heated and melted into a paste), the heating plate is withdrawn, and then the manipulator follows the cam curve. Downstream, the cap and the bottle mouth are pressed and welded together. After the welding cap is completed, the welding head is returned to the capping station, and the welding cap process is completed (the concentricity of the welding cap does not exceed 0.5 mm).

The heating sheet is equipped with monitoring voltage or current to display the temperature in real time. The parameters such as temperature and time are provided with upper and lower limits on the interface. When the temperature is over temperature, the alarm will be automatically alarmed, and the heating sheet will be in and out.

The heating plate is equipped with a circulating water tank to ensure the service life of the heating plate. At the same time, the heating sheet has the alarm function when the power is turned off, and after the sudden power failure or emergency stop, the heating sheet automatically exits. Before pressing, according to the requirements of the actual production process, through the adjustable exhaust mechanism (the exhaust method adopts the roller type exhaust, the exhaust volume can be adjusted), the appropriate amount of air in the bottle is discharged and then pressed and welded, Guarantee the quality of subsequent processes. After that, the robot moves off along the cam curve, and the bottle after the welding is sent to the bottle orbit through the bottle discharging mechanism, and enters the next process. The welded plastic bottle large infusion bottle is smoothly conveyed on the bottle orbit by the robot and output to the sterilization collection area through the bottle orbit.
