ABSTRACT:
A venetian blind cutting machine including a support framework, a cutter module replaceably mounted on a top of the support framework, two air cylinders for driving cutters mounted in the cutter module, two sets of quick couplings for connecting the air cylinders to an upper cutter, a strip cutter, and a lower cutter mounted in a cutter seat of the cutter module, a blind supporter pivotally connected to the support framework in front of the cutter module for stably supporting a venetian blind to be cut, and a blind locating assembly fixedly mounted behind the cutter module for adjustably deciding the length of the venetian blind to extend into the cutter module for cut. With the cutter module containing three cutters for an upper rail, strips, and a lower rail of the venetian blind and the two air cylinders connected to the cutters via the quick couplings, the cutters can be driven by the air cylinders to neatly cut the rails and strips of the blind by only one cut. Moreover, a different cutter module can be quickly replaced to cut venetian blind having differently shaped rails and strips.
