绞绳机

一、概述
绞绳机是一种粗选净化设备，与水力碎浆机配套使用，使含在废纸中的杂质如铁丝、细绳、塑料、棉纱等在水力碎浆机运行过程中不断旋转缠绕，形成一根股绳并被连续拉出、排掉，使浆料得到初步净化。该机具有工作效率高，动力消耗低，结构简单，操作维修方便等优点。

二、结构原理
绞绳机由机架、电机、减速器、传动链条、上压辊及起落装置、绞轮、挂轮及导辊等部分组成（见附图）。电机经减速器通过传动链条带动绞轮缓慢转动，水力碎浆机中缠绕性杂质形成股绳被连续拉出，股绳的运行速度和方向根据工艺要求可以调节。上压辊对股绳压紧，其压力可通过起落装置加以调节。导辊对股绳起到支承作用，减少股绳运行阻力。绞绳机整机组合成一体，结构简单、紧凑。

Ragger is a kind of equipment for roughing and purifying and is used together with hydrapulper, making the impurities of the waste papers (e.g. iron wires, string, plastic, cotton yarn, etc.) constantly rotating and winding in the running process of the hydrapulper to form a rope which then is pulled out and discharged continuously, thus making the pulp stock reach a preliminary purification.

Features of Ragger:
Ragger has the following advantages: high efficiency, low power consumption, simple structure, easy operation and maintenance, etc.
