回转盖板正转漏梳原因与控制

The Reason and Control of the Carding Neglect of the Positive Transfer of the Rotating Flat

为了控制盖板正转漏梳的问题,分析回转盖板正转梳理漏梳的原因及控制措施。指出:回转盖板正转梳理过程中气流、工艺、机械状态等因素影响会出现漏梳,如回转盖板后部气流正压过大、回转盖板链条伸长起浮、盖板-锡林转移梳理过程差异、预分梳能力差异等是造成漏梳的主要原因;通过合理控制后部气流、合理设计梳理区工艺、增加前后固定齿条盖板、提高预分梳能力等措施,能够达到控制回转盖板正转漏梳、提高梳理质量的目的。

In order to control the problem of the carding neglect of the positive transfer of the rotating flat,analysis is done to the reasons of the same and control measures are given. It is pointed out that factors resulting in carding neglect includes air flow, process, equipment state such as excess air positive pressure in the rear part of the flat, chain joggling of the rotating flat, the flat-cylinder carding transfer difference,and pre-gilling difference. Through proper con- trol of the rear air flow, proper carding process, increase of the front and rear flat with rack, im- provement of pre-gilling capacity,the problem of the carding neglect of the positive transfer of the rotating flat is solved with better carding quality.
