When working, the servo motor drives the bowl tooth by the cone tooth to rotate the rod nut, and the rod moves up and down by the action of the thread, so that the heating plate module moves up and down. Because the rod moves up and down, the right-angle reduction box needs to be designed with space for the rod to move up and down. In addition, the space occupied by the right-angle reduction box formed by the bowl tooth and the cone tooth is large, the volume of the driving mechanism is large, and a relatively large space needs to be occupied above the base, so the volume and weight of the entire product are large and the cost is high.
