In order to meet demand, empty plastic
5 gallon containers are manufactured in high volumes. When containers are
filled and shipped, there will always be some defects that will cause leaks.
With leak detection equipment in the production line, plastic bottles are
tested as they move along the line and rejected if they are defective.
Tests conducted on empty containers
can identify leaks before bottles reach the end of the production line, significantly
reducing the possibility of a bottle recall.
The products can be used for on-line
inspection and are available in options for rang of size and capacity of empty
This equipment is comprised of the frame, the frame shell, the
seat, the spindle, the gear wheel, the carrier gear, the upper top plate.
This consists of a water tank, a leak test shelf, an inlet for the
barrel of star wheel gear, a discharge for the barrel of star wheel gear, an
outlet for the barrel of star wheel, a transmission, a motor, a pneumatic motor
component, and a conveyor chain.
A rotary leak machine with 12 workstations is used with water,
electricity, and instrument Air. As a first step, the straight conveyor
transported barrels into the barrels of star wheels. When the main engine is
running, the solenoid valve of the leak test bench opens, the control cylinder
pushes down the barrels of the leak test bench.
With the test shelf placed in the water tank and the air valve
opened to inflate the barrel simultaneously, the air pressure is 0.6-0.8MPa, and
cracked barrels or barrels with holes will bubble when they are immersed in the
water fully after 1-2 seconds. With this method, the operations staff are able
to easily spot bad barrels and remove the ones that are defective.
