Different Working Parameters of Biomass Processing with the Band Saw out, the Impact of Vibration Frequency and the Rate of Tooth

摘要

The MJ3310B type woodwork sawing machine as the research object, research and processing of biomass materials, and how to determine the band saw off the number of the tooth loss. The use of high precision VibSys Beijing pop vibration analyzer and vibration signal acquisition and processing software under different operating conditions, the acquisition of transverse vibration of band saw blade displacement, and the power spectrum analysis. The analysis shows that: for the MJ3310B type woodworking band sawing machine, use the 125mm width of blade, is the main factor affecting the band saw tooth loss: saw wheel speed, weight weight, feed rate. No load when the saw wheel spindle speed, RAM weight, upper and lower saw blade spacing are adjusted to the most appropriate circumstances, determination of transverse vibration frequency between 31Hz～43Hz, the saw blade has produced at least 1 lost tooth defect; the feed speed under proper cutting of poplar, determination of transverse the vibration frequency is between 33Hz～51Hz, the saw blade has produced at least 1 lost tooth defect. With the increase of the number of teeth out of band saw blade, saw blade vibration frequency increases, increases from 33Hz to 72Hz. According to the change of transverse band saw blade vibration frequency, can be inferred the number of teeth in the reverse band saw off, which can fault on-line monitoring of band-saw blade.
