The invention relates to an improved clothes folding machine and belongs to the technical field of improvement of clothes folding machines. The improved clothes folding machine comprises a motor (15) and a clothes folding machine body, wherein the clothes folding machine body comprises a fixed plate (1) and four movable plates; the four movable plates are rotatably connected with four edges of the fixed plates (1) respectively; the motor (15) is fixed below the fixed plate (1); the improved clothes folding machine is characterized by further comprising four support rods (14), four clothes folding rods and four air cylinders; one air cylinder is fixed at the upper part of each movable plate; each air cylinder is vertically connected with one clothes folding rod; when any movable plate works, the air cylinder at the upper part of the movable plate on one side, symmetrical about the fixed plate (1), of the movable plate pops up the corresponding clothes folding rod to press bent parts of clothes to be folded, and the motor (15) is used for controlling the movable plate to rotate via the support rods (14); when the clothes folding machine works, the air cylinders control the corresponding clothes folding rods to stretch out and fix folded parts of the clothes, so various folding marks or distortion of the folded parts of the clothes can be avoided.
