This utility model provides a feeding compensation device for a
fully automatic film coating machine, including a supporting base plate placed on an external lifting platform for supporting materials, a plurality of placement slots equally spaced on the supporting base plate, a plurality of support rods with one end set on the supporting base plate within each placement slot and the other end located outside the placement slot, and a counterweight block set on the other end of each support rod. The length of the support rod is greater than the length of the placement slot, and the support rod is fitted with the placement slot with a clearance. By subsequently increasing the lifting
stroke of the lifting platform, the lifting frequency of the lifting platform is reduced, thereby reducing the
energy consumption of the lifting platform due to frequent start-stop.
