如图2(a)和(b)所示，中心螺杆8上设置有中心叶片19，中心叶片19和中心轴18固连，行星螺杆13上设置有行星叶片21，行星叶片21和行星搅拌轴20固连。As shown in Fig. 2 (a) and (b), center screw rod 8 is provided with center vane 19, and center vane 19 is fixedly connected with central shaft 18, and planetary screw 13 is provided with planetary vane 21, planetary vane 21 and planetary stirring shaft 20 fixed connections.
如图3所示，变径变螺距式行星搅拌装置具体工作流程如下：As shown in Figure 3, the specific working process of the planetary mixing device with variable diameter and variable pitch is as follows:
搅拌时，中心螺杆8顺逆时针转动时，其左右旋中心叶片19将物料向上输送，由于中心叶片19从下到上的直径逐渐减小，螺距逐渐减小，在向上输送的过程中对物料形成挤压作用，物料向行星螺杆13方向挤压运动，同时少量物料在自重作用下回落；三个行星螺杆13逆时针方向自转，其右旋行星叶片21将物料向上输送同时挤压物料，由于行星叶片21从下到上的叶片直径逐渐增大，螺距逐渐增大，行星螺杆13上部较大的行星叶片有利于汇集从行星螺杆13向上输送的物料和中心螺杆8因惯性和挤压作用向行星螺杆13运动的物料。物料向上输送同时相互作用，有助于物料充分混合。动刮板15转动将粘附在筒体16上的物料刮下，搅拌过程中物料多轨迹交叉运动，提升搅拌效率与搅拌质量。When stirring, when the central screw 8 rotates counterclockwise, its left and right rotating central blade 19 conveys the material upwards. Since the diameter of the central blade 19 gradually decreases from bottom to top, the pitch gradually decreases. During the upward conveying process, the material is The extrusion effect is formed, and the material is extruded in the direction of the planetary screw 13, and at the same time, a small amount of material falls back under the action of its own weight; the three planetary screws 13 rotate counterclockwise, and their right-handed planetary blades 21 convey the material upward and squeeze the material at the same time. The diameter of the blades of the planetary blades 21 increases gradually from bottom to top, and the pitch gradually increases. The larger planetary blades on the upper part of the planetary screw 13 are conducive to collecting the materials conveyed upwards from the planetary screw 13 and the central screw 8 due to inertia and extrusion. The material moved by the planetary screw 13. The material is transported upwards and interacts with each other, which helps the material to mix thoroughly. The moving scraper 15 rotates to scrape off the material adhering to the cylinder 16. During the mixing process, the material moves in multiple tracks and crosses, which improves the mixing efficiency and mixing quality.

The materials do small-scale circular motion and upward movement; the material moves under the action of its own weight, and the diameter and pitch of the central blade 19 gradually decrease at the same time to squeeze the material. During the mixing process, the amount of material conveyed upward by the central screw 8 changes from large to small, and the amount of material conveyed upward by the planetary screw 13 increases from small to large. The material gathers in the upper part of the mixing drum and performs extrusion and diffusion motions to the surroundings. The moving scraper 15 and gravity Under the action, it moves obliquely downward along the cylinder wall.
