The utility model provides a composite frame fence of a leaf beater, belonging to the technical field of tobacco production equipment. The composite frame fence of a leaf beater includes a frame fence body, which is divided into three areas. The rhombic hole in the first area forms a leaf tearing area with high tearing efficiency, and the circular hole in the second area forms a drainage area, so that the smaller smoke sheet material can be separated from the frame fence in time. It may reduce unnecessary secondary strikes and reduce the crushing rate. At the same time, it can avoid the over-load of the frame bar in the process of threshing, and form a secondary tearing area in the rectangular hole of the third area, so that the remaining large materials can be torn again and realize the secondary tearing. Through the frame bar, the number of pure blades that can be sorted by the first air separator is increased, and the latter stage, especially the third and fourth stage scoring equipment is entered. As the amount of tobacco material decreases, the amount of crushing decreases. The aim of controlling the large fragment rate, stably increasing the medium fragment rate and reducing the fragment rate was realized, and the uniform shape, regular edge and high middle fragment rate of smoke were ensured.
【技术实现步骤摘要】
一种打叶机复合式框栏
本技术属于烟草生产设备
,具体地说,涉及一种打叶机复合式框栏。
技术介绍
目前国内打叶机上使用的框栏主要有四种形状,分别是方格形、横条形、菱形、圆形,框栏的开孔形状均为统一的形态单元。打叶时高速旋转打辊动刀带动烟叶与框栏刃口进行接触,完成“撕打”,实现叶梗分离。框栏形状和尺寸直接影响打叶质量,目前一至三级打叶普遍使用的是菱形框栏,菱形框栏开孔率较小,采用同一规格的框栏进行打叶,打后叶片的形状不规则,中片比例偏低,综合质量不稳定,且打叶强度大,导致打叶过程中框栏过叶负荷较大,部分尺寸合格的烟片无法通过框栏,重复加工,打叶造碎增加,不利于提高烟叶的利用率。为了满足复烤后片烟形状均匀、边缘规整、中片比率高的需求,需要提供一种打叶机复合式框栏,以便降低切丝造碎,利于掺配后叶丝化学成分均匀。
