摘要：高效锥型磨浆机打浆实质是通过机械作用，使纤维的横纵方向细纤维化。纸浆的打浆度的好坏取决于对高效锥型磨的控制效果是否优良，进而亦会影响成纸的品质。打浆度越高，成品纸张的强度和质量也相对越高，但相对浆料的脱水能力就会降低。因此，合理控制高效锥型磨浆机打浆过程是保证纸机稳定生产，这是保证成品纸质量的关键一步。

其中的进给机构就是纸张品质的核心，使之效率高、适应性强、操作灵活、打浆度控制精确等特点。本次的毕业设计课题是高效锥型磨进给机构设计，进给机构是高效锥型磨的重要组成部分，它直接影响到打浆的效果。在设计过程中，首先分析和研究了高效锥型磨进给机构的工作原理，对其部件的结构进行了设计方案论证，然后进行了结构设计、计算和校核。最后我绘制了进给机构的装配图及主要部件的零件图。

The Design of Efficiently Conical Refiner Feed Mechanism

Abstract: The efficiently conical refiner essence is through the mechanical action， cutting the fiber cross-sectional and longitudinal fine fibrosis. The higher the refiner beating degree， into the higher the strength of paper，paper evenness，the better，but the slurry dewatering capacity decrease accordingly. So reasonable control beating the refiner is guarantee the stability of efficiently conical refiner production，the key to ensure the quality of paper process.

Efficiently conical refiner control effect is good or bad directly affects the pulp beating degree，thus affect the quality of the paper，the feed mechanism is the core of the paper quality，make the high efficiency，strong adaptability，flexible operation， beating degree control precision，etc. The graduation design topic is the design of efficiently conical refiner feed mechanism，feeding mechanism is the important component of a efficiently conical refiner，which directly affects the grinding effect. First，analysis and research of the efficiently conical refiner feed mechanism，and then argument the components of the structure of the design，then has carried on the structural design，calculation and verification. Finally draw the feed mechanism assembly and the main parts.

Key words：pulp；refining；efficiently conical refiner；feed mechanism
