OSCILLATING PRESSURE SYSTEM FOR VERTICAL FORM FILL SEAL MACHINE

摘要

An apparatus for producing an oscillating force that actuates a mechanism and comprises the following components: a frame; channels attached to each of the sides of the frame; a servo motor positioned on the top of the frame; a shaft assembly having an offset slider assembly where the top end is attached to the servo motor and the bottom end is positioned adjacent to the bottom of the frame; a pusher block having a rectangular shaped opening therein and horizontal rails each attached to opposite side of the pusher block and each is slidably positioned in the channels attached to the sides of the frame and the off-set slider assembly being positioned in the rectangular shaped opening of the pusher block; an actuation mechanism attached to the pusher block that provides a forward and backward oscillating motion to the pusher block; and a heat sealing mechanism that is actuated by the actuation mechanism. This apparatus is used in conjunction with the heat sealing mechanism of a VFFS machine for forming and filling pouches.
