The sheet seam with hot melt adhesive can quickly and fully solidify and cool when passing between the cooling outer mold 8 and the cooling inner mold 9.

[0016] Further, in order to enable the seam welding equipment to adapt to the processing of different types of pipe diameters, the height positions of the hot air gun 2 and the glue extruding machine 3 can be adaptively adjusted according to the size of the pipe diameter, so as to ensure that the hot air gun 2 and the glue extruding machine 3 can accurately align with the seam position of the sheet. The first fixed frame 1 is provided with a vertical guide rod 10, and a guide sleeve 11 is fitted and installed on the guide rod 10. The guide sleeve 11 can be vertically lifted along the guide rod 10.

[0017] The hot air gun 2 and the glue extruding machine 3 are arranged on the guide sleeve 11. A vertical moving cylinder 12 is further arranged between the guide sleeve 11 and the first fixed frame 1. The cylinder barrel of the vertical moving cylinder 12 is arranged on the first fixed frame 1, and the piston rod of the vertical moving cylinder 12 is connected to the guide sleeve 11. The piston rod of the vertical moving cylinder 12 can be extended and retracted to synchronously lift the hot air gun 2 and the glue extruding machine 3 in the height position, and then adjust the height position of the hot air gun 2 and the glue extruding machine 3 relative to the spirally wound pipe material as needed.

[0018] Further, in order to realize the position adjustment of the guiding and clamping frame between the first fixed frame 1 and the second fixed frame 4, as shown in Figure 3 and Figure 4 The first clamping roller 5 is located at the upper side of the second clamping roller 6.

When the handle 26 is rotated, the swing rod 23 can be driven to move in extension and retraction relative to the clamping seat 25 through the matched screw rod 24 and screw hole. During the above movement, the second clamping roller 6 remains in a relatively fixed state. After the first nut 15 is loosened, the first clamping roller 5 can be adjusted in swing relative to the second clamping roller 6, thereby realizing the tight clamping and guiding of sheet materials of different thickness types.
