Referring to fig. 10, in order to better show the process of the thermal welding apparatus for preventing human body injury, the present embodiment provides an implementation method of the thermal welding apparatus for preventing human body injury, including the following steps:

s101: feeding, namely bending two workpieces to be welded and placing the two workpieces in a joint shape in a gap between the left baffle mechanism 400 and the right baffle mechanism 500;

s102: contraposition, the horizontal position of the welding pressing block 367 is adjusted through the adjusting cylinder 362 and the driving assembly 340 until the welding pressing block 367 is positioned at two sides of the workpiece;

s103: and in the fusion welding, the pushing cylinder 365 extends forwards to drive the fusion welding pressing blocks 367 on the two sides of the workpiece to approach each other until fusion welding raw materials between the two workpieces are fused at high temperature.

In summary, the following steps: according to the hot-melt welding device for preventing human body from being damaged and the implementation method thereof, the left baffle mechanism 400 and the right baffle mechanism 500 are matched with each other to form a space capable of accommodating the welding mechanism 300, so that a protective barrier for protecting a human body is formed; the semi-closed structure fixed outside forms a hot-melt welding device through internal fusion, so that the alignment deviation generated in the fusion process can be conveniently adjusted, and the accurate execution of hot-melt welding is facilitated; the hot-melt welding is realized by mutually extruding the double-welding pressing blocks 367, so that the local precision of the hot-melt welding can be improved, the hot-melt welding area is prevented from being enlarged, and the operation can be simplified.
