With the above structure, after the workpiece is fixed, the edge-wrapping assembly can be driven to move by the subsequent pneumatic moving assembly. During the operation, the extension rods of a pair of cylinders 13 extend first, so that when the edge-wrapping assembly moves in one direction, it can scrape a groove on the bottom of the PVC film with the cooperation of the lower roller 17. When the edge-wrapping assembly returns, the extension rods of cylinders 13 are controlled to retract, thereby causing the lower roller 17 and the grooving blades 18 to drop in height. This causes the upper pressure roller 16 and the inclined roller 26 to move downward. Specifically, the inclined roller 26 is used to press the PVC film tightly against the corner of the workpiece.
