The utility model discloses an automatic tool for PVC (
polyvinyl chloride) ground coiled material seam treatment, which relates to the technical field of PVC coiled material paving, and comprises a driving trolley, a movable arm, a positioning wheel, a mounting buckle, a hot melting
welding machine and a
welding wire frame. Automatic tracking of the
welding path is achieved, and the deviation problem in manual operation is effectively avoided. The thermofussion welding
machine adopts inclined installation design, the best welding wire melting angle is ensured, meanwhile, the fastening mode that the installation buckles are matched with the rubber pads is adopted, the equipment stability is ensured, and the thermofussion welding
machine can be rapidly disassembled and assembled conveniently. The welding wire holder realizes automatic supply of the welding wire through the winding mechanism capable of adjusting the
friction force, so that the tedious operation of manual wire feeding is avoided.
