Abstract:
A Venetian blind cutting machine comprising:a mold assembly having a main block provided with a guiding slot thereon which has a closed end and an open end, a sliding block slidably received in said guiding slot, an opening formed between the closed end of the guiding slot and the sliding block for receiving slats of the Venetian blind therein; said guiding slot provided with a stopping portion adjacent to the open end for stopping said sliding block; a cutter movably installed at said main block of said mold assembly for free shifting along a direction substantially parallel to said guiding slot; at least one driving bar having one end thereof fastened to said cutter; said driving bar being substantially parallel to said guiding slot and being driven to shift along a direction substantially parallel to said guiding slot, a joint block having at least one opening for receiving said driving bar and holding said driving bar therein by friction; a connecting bar, which is substantially parallel to said driving bar, having one end thereof fastened to said joint block, and the other end thereof fastened to said sliding block; wherein, when said driving bar is driven, said cutter, said joint block and said sliding block move along with the driving bar and said sliding block presses the slats first to lock the slats in said closed end of the guiding slot while said joint block moves with the driving bar and the sliding block presses the slats, the driving force of said driving bar overcomes the friction of said joint block so that said joint block will loosen said driving bar and said driving bar will move continually and drive said cutter to move along with the driving bar.
