Technical Field
[0001] This invention relates to a three-axis magnetic levitation trimming device for woodworking edge banding machines, and pertains to the field of woodworking machinery manufacturing technology. Background Technology
[0002] Currently, edge banding machines on the market are woodworking machines that replace manual labor, integrating the edge banding process with feeding, gluing, cutting, front and back trimming, top and bottom trimming, top and bottom fine trimming, top and bottom scraping, and polishing into a highly automated machine. However, the trimming device uses a traditional mechanical transmission structure, which suffers from slow response speed and poor trimming accuracy when automatically tracking the trimming process, requiring further improvement. Patent CN2024119236128 discloses a single-axis tracking unit, but it only changes the bottom drive to a single-axis magnetic levitation drive, failing to further improve the speed and accuracy of chamfering.
[0003] The purpose of this invention is to provide a three-axis magnetic levitation chamfering device for a woodworking edge banding machine, which solves the defects of slow chamfering speed and poor precision of edge banding machines, and maximizes the satisfaction of the market demand for environmentally friendly automatic edge banding machines.
