  "description_excerpt": "The present invention relates to edge banding machine, and more particularly to an improved structure of edge banding machine, which can effectively reduce problem of machining error during processing.\n\nFIG. 1 illustrates a conventional edge banding machine. The edge banding machine 90 comprises a platform 91, a feeding mechanism 92, an edge band transmission mechanism 93 and a glue applicator 94. The feeding mechanism 92 comprises a feeding roller set 921 for feeding a workpiece to be processed forward, enabling the workpiece to be delivered to the edge band transmission mechanism 93 and the glue applicator 94 at the platform 91. When the workpiece is moved to the glue applicator 94, one side of the workpiece is disposed with a layer of hot melt glue for the bonding of an edge band of a predetermined length. The predetermined length of the edge band is determined according to the side length of the workpiece. In order to enable the edge banding machine to get the data of this predetermined length, the edge banding machine 90, in design, uses a workpiece driven roller 95. When the workpiece is move to the workpiece driven roller 95, the workpiece drives the workpiece driven roller to rotate, and the predetermined length is measured according to the angle of rotation of the workpiece driven roller 95.\n\nHowever, the glue-applying shaft 941 of the glue applicator 94 of the edge banding machine 90 and the edge band transferring shaft 931 of the edge band transmission mechanism 93 are respectively driven by a respective motor. After a long use of the edge banding machine 90, the workpiece driven roller 95 may wear.",
