　　模块化组合‌：“子”与“母”可根据工艺需求灵活配置转速、转向及螺旋叶片形式。

　　子母螺旋输送机由‌母轴‌和‌子轴组成，两者共用或独立驱动，通过时序控制完成一个完整的称量周期：

　　快速喂料阶段（母轴主导）‌

　　在称量周期初期，‌母轴全速运转，利用大螺距或高转速产生强大的轴向推力，将物料快速输送至计量仓 。

　　此阶段目标是缩短非称量时间，提高整体生产效率，此时子机通常处于关闭或待机状态 。

　　‌精确补料阶段（子轴主导）‌

　　当物料接近目标重量时，‌母轴关闭‌停止进料，防止过量 。

　　‌子轴启动(或单独低速运行)，利用小直径、小螺距或低转速特性，对物料进行‌微量、平稳‌的推送 。

　　此阶段依靠子轴的精细推力克服物料惯性，确保蕞终落料重量精准落在允许误差范围内，满足高精度称量需求 。‌‌精度±1g，±10g，±50g，±100g，±200g，±500g以内等，按需定制。

　　Modular combination: The "child" and "parent" can be flexibly configured in terms of speed, direction, and spiral blade form according to process requirements.

　　The sub-master screw conveyor consists of a master shaft and a sub-shaft, which can be driven together or independently. It completes a complete weighing cycle through timing control:

　　Rapid feeding stage (driven by the main shaft)

　　At the beginning of the weighing cycle, the main shaft rotates at full speed, utilizing a large pitch or high rotational speed to generate strong axial thrust, rapidly conveying the material to the metering bin.

　　The goal of this stage is to shorten non-weighing time and improve overall production efficiency. At this time, the sub-machine is usually in a closed or standby state.

　　Precise feeding stage (sub-axis-driven)

　　When the material approaches the target weight, the main shaft closes to stop feeding to prevent excess.

　　The sub-shaft is activated (or operated at low speed independently), utilizing its small diameter, small thread pitch, or low rotational speed characteristics to gently and steadily push the material in small amounts.

　　At this stage, the fine thrust of the sub-axis is relied upon to overcome the inertia of the material, ensuring that the final material weight falls within the allowable error range and meets the high-precision weighing requirements. Accuracy within ±1g, ±10g, ±50g, ±100g, ±200g, ±500g, etc., can be customized as needed.
