[0024] This invention features a storage base on one side of a second placement platform. A smooth roller is movably installed within the storage base, and the smooth roller is fitted onto a rotating rod. One end of the rotating rod is mounted on one side of a cavity within a third mounting base, and the rotating rod is diagonally inclined within the cavity, with the intervals gradually increasing. A set of rotating rods at the bottom of the cavity has a main gear, and one end of the rotating rod is connected to a motor inside the third mounting base. A set of rotating rods at the top of the cavity only rotates, while the remaining rotating rods have a driven gear at one end. The smooth roller on the rotating rods with the main and driven gears also has rotating ridges. When a long door or window panel needs to be cut into smaller sections, the longer panel is clamped by a fixing device. After the first and second shearing bases cut a portion, the fixing device releases the longer panel, and then a pusher on the top of the second mounting base... The delivery base pushes the cut window and door panels to one side of the second placement platform and slides downwards along the inclined surface of the second placement platform, contacting the smooth rollers installed inside the storage base. After the first set of smooth rollers slides the window and door panels into the storage base, the other smooth rollers, driven by a motor installed in the third mounting base, rotate counterclockwise. These smooth rollers also have rotating ridges, which transport the window and door panels to one side inside the storage base for easy collection. The smooth surface of the rotating ridges reduces friction between the window and door panels, preventing the counterclockwise rotating smooth rollers from pushing the panels upwards and affecting the normal operation of the device. Furthermore, the gradually increasing distance between the rotating rods with the rotating ridges and the cut waste and solid particles from the window and door panels helps separate the waste and solid particles from the panels, preventing them from getting stuck inside and requiring secondary cleaning.
