为了保证工业大麻剥麻机的剥麻质量,提高各运动部件传动效率及工作稳定性,开展了工业大麻剥麻机传动系统的设计工作。本研究对带传动、链传动和齿轮传动等机械传动方式进行了分析,结合工业大麻剥麻机的传动特点,确定本样机从动力到碎茎装置、多级碎茎装置之间、碎茎装置到剥麻装置、以及相互啮合的碎茎辊或剥皮滚筒分别由三角皮带传动、链传动和齿轮传动相结合的多级组合传动方式。并根据样机设计工效及接麻装置设计尺寸,确定了样机喂入线速度为1.96 m/s,麻皮抛出线速度为5.56 m/s,以上述参数为依据,根据试验结果确定了第1(2)对碎茎辊转速为288 r/min,第3(4)对碎茎辊转速为310 r/min,剥麻滚筒转速为443 r/min,此时第1对碎茎辊与第3对碎茎辊之间的线速度差为0.15 m/s,第3对碎茎辊与剥麻滚筒之间的线速度差为3.45 m/s。试验结果表明,本研究设计的样机运动部件之间的传动方式能够满足剥麻机传动部件的工作要求,试验结果表明,确定的运动参数达到了较好剥麻效果。

In order to find the economy and effective mechanical transmission between the moving parts of decorticator of hemp fresh stem, the transmission way was designed. Based on the comparison of main mechanical driving way, a transmission way of belt transmission, chain transmission and gear trans- mission ways was chosen. According to the prototype design efficiency and size, the linear velocity of prototype feeding is 1.96 m/s, and the throwing linear velocity of discharge hole is 5.56 m/s. Based on the above parameters, we con_FLrmed that first broken stem roller speed is 288 r/min, third broken stem roller speed is 310 r/min, the strip roller speed is 443 r/min, linear velocity contrast between first and third broken stem roller is 0. 15 m/s, linear velocity contrast between third broken stem roller and the stripping drum is 3.45 m/s. Test results show that transmission way of the prototype between the moving parts can satisfy work requirements, and the motion parameters can achieve satisfying work effect.
