Automatic flow meter filling machine for PET bottle personal and
home care liquid products
Main components
Bottle feeder + automatic cap elevator and unscrambler + inlet and
outlet bottle template + cap-pressing mechanism + rejection
mechanism + electrical control etc.
Bottle-feeding by screw rod
The screw rod separates the bottle and is designed with bottle-in
detection device, no bottle no cap-sending and the machine will
automatically stop and alarm, if there is bottle stuck.
Cap-feeding
Servo cap-sending greatly reduces the possibility of jamming and
improves efficiency and quality.
Cap-pressing head
The pressing head uses a contouring device depending on the special
shape of the cap.
Using the principle of vacuum suction cap, the cap is effectively
sucked into the inside of the claw head, and mechanical valve
control is used. When the pressing operation is completed, the head
releases the cap.
A cushioning mechanism is designed above the pressing head so that
the head protects the cap and the bottle during the capping process
to prevent damage.
Changeover for different products
All star wheel changes are replaced as a whole. The replacement
parts include the bottle-in star wheel, the bottle-out star wheel,
middle star wheel, the inlet and outlet guide plates, and the outer
ring.
Cap unscrambler with visual detection
The pressed cap unscrambler adopts “position” mode to arrange the
disorderly cap regularly. The camera detect the cap direction and
change it if it’s the other direction. Then, the cap is sent into
the channel in an orderly manner by a vacuum inverting device, and
then outputted from the cap channel in an orderly manner, and the
cap is supplied to the capping machine through the cap divider.
Rejecting of unqualified products
After cap-pressing, there is a double conveyor structure with an
intelligent detection device. The qualified bottles are normally
transported, and the unqualified (no cap, higher cap) bottles are
automatically shunted to another conveyor belt by using the
swinging cylinder. When there is bottle stuck, the machine
automatically stops and starts again after the problem is solved.
