Theory of Operation
The Smartwrapper 60™ is a single motor driven polypropylene over wrapping machine with the
built-in ability to add a tear tape for easy packaging opening. It is powered by 220 volt AC single
phase, consuming 2500 watts. The Smartwrapper 60 is adjustable to accommodate a package
size up to 30 mm high, 220 mm wide and 145 mm long. It is variable speed up to 50 pieces per
minute.
The machine utilizes a series of cams and levers to minimize the need for complex electrical
sensors and logic circuits. This allows the machine to run continuously with a minimum of
downtime for maintenance. No air is required.
The single motor drives a shaft with nine cams, each cam controls a function of the machine.
Levers running on the cams connect to the various parts of the machine to move the product
through the machine and wrap poly film around it.
The product to be wrapped is stacked in the hopper. The box lifters (one on each side of the
hopper) lift the stack of boxes, leaving one on the bottom to be pushed through the hopper exit
guides by the Pusher Bar.
