摘要
目前环模制粒机间隙人工调节时只能静态调整,调整精度低、费时,且不能实现对整个加工过程的有效监测,针对此问题提出一种环模制粒机模辊间隙智能调整机构。该机构对现有制粒系统进行结构性能改进,以弥补人工调整环模制粒机间隙的不足。首先,对SPZL600型双辊制粒机模辊间隙调整机构进行设计;其次,建立模辊间隙智能调整机构数学模型;最后,对样机进行试验。结果表明,试验测量间隙与理论间隙几乎完全重合,说明间隙智能调整系统准确性高;当检测转速输入为400 r·min^(-1)时,系统在6.0 s内完成间隙调整,系统响应具有高效性。该机构增强了生产安全系数与智能化程度,提升产品的持续竞争力,对其他制粒机具有借鉴意义。
Previously,the gap of the ring die granulator could only be adjusted statically when manually adjusted.The adjustment accuracy was low and time-consuming,and effective monitoring of the entire processing process could not be achieved.Aiming at this problem,an intelligent adjustment mechanism for the gap of the ring die granulator was proposed.The mechanism improved the structural performance of the existing granulation system to make up for the shortcomings of the previous manual adjustment of the gap of the ring die granulator.Firstly,the mold roller gap adjustment mechanism of the SPZL600 twin-roll granulator was designed.Secondly,the mathematical model of the intelligent adjustment mechanism of the die roll gap was established.Finally,the prototype was tested.The results showed that the experimental measurement gap was almost completely coincident with the theoretical gap,indicating that the accuracy of the gap intelligent adjustment system was high.When the detection speed input was 400 r·min^(-1),the system completed the gap adjustment within 6.0 s,and the system response was efficient.The mechanism enhanced the safety factor and intelligence of production,improved the continuous competitiveness of products,which had reference significance for other granulators.
