双立轴烟秆切割机构的设计与试验

设计了一种适合烟秆切割的双立轴圆盘式切割机构。在自制的烟秆切割试验台上,对切割速度、装置的前进速度、主从切割刀片的径向重叠量等进行了单因素试验和多因素正交试验。单因素试验结果表明,在切割速度350 r/min时,功耗为1 718.8 W,切断率为94.33%;在主从切割刀片的径向重叠量为15 mm时,功耗为1 500.73 W,切断率为95.6%;在装置的前进速度为0.6 m/s时,功耗为1 608.13 W,切断率为96.83%。正交试验结果表明,当切割速度为300 r/min,主从切割刀片的径向重叠量为15 mm,装置前进速度0.6 m/s时,功耗为1 480.26 W,切断率为97.21%。

Design and experimental study on the cutters with double vertical shafts for the tobacco stalks

In this paper, a disc cutter with double vertical shafts is designed to cut the tobacco stalks. The single factor and orthogonal experiments are carried out in the self-made tobacco stem cutting device for the factors of the cutting speed, the forward speed of the device, and the radial overlap gap between the active plate and the driven knife plate, etc. By the analysis of the single factor experiment, it is shown that the power consumption is 1 718.8 W, and the cutting rate is 94.33% at the cutting speed of 350 r/min. When the radial overlap gap between the active plate and the driven knife plate is 15 mm, the power consumption is 1 500.73 W and the cutting rate is 95.6%. If the forward speed of the device is 0.6 m /s, the power consumption is 1 608.13 W and the cutting rate is 96.83%. Orthogonal experiment results show that the lowest power consumption of 1 480.26 W and the highest cutting rate of 97.21% could be achieved with the radial overlap gap of 15 mm between the active plate and the driven knife plate when the forward speed of the device is 0.6 m/s.
