[0027] The material guiding and heating mechanism includes four sets of guide channels 13, which are installed at the bottom edge of the housing 1. Each set of guide channels 13 has a rotating rod 17 fitted inside its bottom. A gear 16 is mounted on the outside of the rotating rod 17, and a cam 14 is connected to the top of the rotating rod 17. An annular groove 5 extends into the interior of the four sets of guide channels 13. An internal gear ring 15 is installed at the bottom of the inner side of the annular groove 5, and the internal gear ring 15 meshes with the four sets of gears 16. The top and bottom of the interior of the guide channels 13... A guide groove 23 is provided, and a guide block 21 with sliding fit and a spring 22 elastically connected to the guide block 21 are provided on the inner side of the guide groove 23. A movable seat 18 is installed on one side of the two sets of guide blocks 21, and the movable seat 18 extends out of the outside of the guide groove 13.

[0033] When the raw materials fall into the flow guide groove 13 from the material flow channel, the heating structure of the second heating plate 12 is started, and then the raw materials are guided into the space between the four sets of movable seats 18 and the second heating plate 12 through the guide of the flow guide groove 13, during which the rotation of the annular groove 5 drives the inner ring gear 15 to mesh with the four sets of gear wheels 16, so as to drive the four sets of gear wheels 16 to rotate the rotating rod 17 and the cam 14, and the cam 14 is intermittently in contact with the movable seat 18 and is extruded, when the movable seat 18 is extruded, the guide block 21 moves in the inner side of the guide groove 23, and under the cooperation of the elastic extension structure of the spring 22, the movable seat 18 reciprocatingly displaces, so as to drive the movable seat 18 and the inclined material guide block 19 to repeatedly push the materials to the heating surface of the second heating plate 12 and the inclined heating block 20, so as to make the raw materials reciprocatingly rebound, further strengthen the heating rate and drying efficiency of the raw materials, and finally make the vertically falling materials re-enter the inside of the installed pipe 9, and the raw materials are re-fed and heated through the rotation of the spiral feeding rod 11, during which the heated moisture is discharged through the moisture discharge hole 2, so as to realize the cyclic heating of the raw materials and greatly improve the drying efficiency of the raw materials.
