为解决PROTOS2-2卷接机组在烟支搓接成型过程中存在的搓板堵塞、皱纹烟支等问题，研制了一种搓接鼓轮自动清洁装置。在运行过程中，清洁毛刷与搓接鼓轮的转动方向相反，且清洁毛刷对搓接鼓轮的压缩量为1 mm时，可以对搓接鼓轮进行有效清洁；采用同步齿形带传动方式，将切纸轮清洁毛刷装置的动力传递给搓接鼓轮清洁毛刷；通过PLC程序控制清洁吹风口，及时清除聚集在搓接鼓轮上方的烟支，清洁吹风的工作时间为15 s，间隔时间为5 s，空气压力为0.2 MPa。结果表明：该装置实现了搓接鼓轮的自动清洁，改进后搓板堵塞减少了3.4次/班次，搓接鼓轮保养减少了3.73次/班次，降低了设备停机次数，提高了设备运行的稳定性。%In order to avoid rolling plate jam and reduce the amount of wrinkled cigarettes, an automatic cleaning device for rolling drum was designed. The cleaning brush rotated in opposite direction to the rolling drum, the drum was effectively cleaned when the brush radially overlapped the drum by 1 mm. The cleaning brush was driven by the same power of cleaning brush of cork drum via a toothed timing belt. PLC controlled air jet was used to blow off the cigarettes gathered on rolling drum for 15 s with an interval of 5 s, air pressure was 0.2 MPa. The results showed that the device cleaned rolling drum automatically; after improvement, the frequencies of rolling plate jam and rolling drum maintenance reduced by 3.4 and 3.73 times per shift, respectively.
