Research on cutterhead structure design and cutting force of new discchipper
Based on the current production status of the process wood chips required for fiberboard,in order to ensure the quality of the wood chips produced by the disc chipper and solve the problem of rapid replacement of the cutting knife of the disc chipper,a new type of disc chipper cutterhead is designed with a differential spiral structure to fine-tune the extension of the cutting knife and replace the knife block as a whole.In this paper,the chipping principle and cutting force of the new cutterhead are studied,and the dynamic analysis of the designed new cutterhead is car-ried out by Adams simulation software to verify the stability of the designed cutterhead at the rated speed,and the clamping force of the loading block is verified and calculated to verify the rationality of the structural design.
