Since each side heating plate is driven to move by the corresponding lateral moving device, the positioning device is positioned by the contact between the component and the side heating plate. Therefore, the hot melt positioning mechanism provided by the present application effectively reduces the labor intensity of the staff in processing products.

The upper surfaces of the four threaded blocks 47 are fixedly installed with hot melt components. The two threaded blocks 47 are relatively moved by the reverse double-threaded rods 43, so that the material can be positioned without using multiple positioning devices for positioning.
