| 摘 要： | 目的]研究混丝加香前振动筛分机的技术改进,解决其筛网网孔在运行过程中被碎丝堵塞,造成筛网筛分效率下降、卷烟端部落丝量和烟支含末率超标的问题。方法]通过在振动筛分机的上层增加一层孔径为4.0 mm筛网,先对物料进行粗筛,第2层筛网孔径1.1 mm不变,并在筛网每格下面挂上冷卷拉伸弹簧,在弹簧上套上橡胶套管,使其在运动过程中对筛网进行敲打,防止筛网堵塞。结果]与改进前相比,改进后的混丝加香前振动筛分机烟丝整丝率提高1.69个百分点,碎丝率降低1.41个百分点;卷烟端部落丝量降低3.29 mg/支,烟支含末率降低1.02个百分点,烟支物理指标稳定性明显提高,有效解决了筛网堵塞的问题。结论]该方法简单易实施,费用较低,筛分效果好,提高了烟丝结构和烟支物理指标的稳定性,具有很好的推广使用价值。 |

Design and Test of Technology Improvement on Vibrating Grizzly before Cut Leaf Tobacco Flavoured |

| Abstract: | Objective] To study technology improvement for solving the sieve mesh plugging by tiny cut tobacco and causing sieving efficiency decreases and dust content and loss of tobacco from cigarette end exceeds of vibrating grizzly before cut leaf tobacco flavoured.Method] Added a sieve mesh for 4.0 mm diameter in the upper layer vibrating screen,sieving cut tobacco firstly;And the second sieve mesh diameter still keeped unchange,positioned spring rolls hung and rubber tube in the second sieve mesh below,knocked on sieve mesh in its athletic process,prevented the ja mming to the sieve mesh.Result] The whole silk screening machine vibration rate of improved mixed filament tobacco was 1.69 percentage points,broken wire tate decreased 1.41 percentage points,cigarettes reduced the amount of wire end tribal 3.29 mg,cigarette end rate 1.02 percentage points lower,somke support significantly improved the stability of physical indicators,effective solution to screen blockage.Conlusion] The method was simple and easy to implement,lessexpensive,screening effect,increased cigarette tobacco and physical indicators of structural stability and had a very good use value. |
