The air blower 30 can pass through the working hole 210 of the body 21 of the heating device 20, and the non-woven fabric 40 is disposed on the outer edge surface of the air bag 31, so that the PE film 50 sheathed by the non-woven fabric 40 can be Positioned by the group 23 and the clamping group 24.

In the present creation, the inflation of the inflatable bladder 31 of the air blower 30 causes the nonwoven fabric 40 and the PE film 50 to be expanded into a cylindrical shape by the top support of the inflatable bladder 31, so that the body 21 of the heating device 20 can be used for PE. The film 50 is subjected to a heat treatment, wherein the non-woven fabric 40 is sleeved on the outer wall surface of the air bag 31, and the PE film 50 is applied to the outer wall surface of the non-woven fabric 40; when the PE hot melt machine of the present invention is operated, the outer cover is applied. The non-woven fabric 40 of the PE film 50 is sleeved on the inflatable bladder 31 and passes through the working hole 210 of the body 21 of the heating device 20, and is supported by the abutting group 23 and the clamping group 24 disposed on opposite sides of the body 21. The position of the outer wall surface of the PE film 50 is offset and clamped so that the air bag 31, the non-woven fabric 40, and the PE film 50 can be positioned to pass through the working hole 210 of the body 21, and then the heating tube is used. 211, the PE film 50 is uniformly heated to allow the PE film 50 to be attached to the outer wall surface of the nonwoven fabric 40. Since the body 21 is assembled by the power pack 25, it can be along the gantry 11 of the susceptor group 10. Moving so that the PE film 50 is coated in the processing process of the non-woven fabric 40, The heating device 20 can be opposite to the inflatable bladder 31, The weaving of the woven fabric 40 and the PE film 50 allows the heating operation of the heating pipe 211 to be quickly completed from one end of the PE film 40 toward the other end, so that the outdoor waterproofing covering material can be mass-produced.

Since the air bag 31, the non-woven fabric 40 and the PE film 50 extend a long distance, the portion of the air bag 31 away from the air blower 30 will sag due to gravity, which will hinder the heating device 20 from standing along the base group 10. 11 moves, so that the bracket 221 abuts against the outer edge of the PE film 50, so that the heating device 20 can be prevented from being disturbed by the sagging inflatable bladder 31 when traveling.

When the PE film 50 is heated and attached to the outer wall surface of the non-woven fabric 40, the operator can stop the operation of the air blower 30 and withdraw the air bladder 31 toward the end of the air blower 30, that is, the air bladder 31. The drawing is pulled toward one end of the gantry 11, and the non-woven fabric 40 and the PE film 50 are pulled toward the other end of the gantry 11, so that the non-woven fabric 40 and the PE film 50 and the inflatable bladder 31 can be separated from each other.

Since the non-woven fabric 40 and the PE film 50 are separated from the airbag 31, the operator has to perform the pulling and receiving operation on the gantry 11, so that the roller 12 is mounted through the gantry 11 to assist the non-woven fabric 40 and The movement of the PE film 50 on the gantry 11 reduces breakage of the PE film 50 due to friction on the gantry 11.

The laser detector 26 mounted on the mounting frame 22 can be detected not only as a position where the heating device 20 moves on the gantry 11, but also during the heating process of the non-woven fabric 40 and the PE film 50. If the air bag 31 causes the non-woven fabric 40 and the PE film 50 to deviate from the long axial direction of the gantry 11, so as to affect the advancement of the heating device 20, the laser detector 26 can sense that the air bag 31 deviates. In the situation, the heating device 20 is immediately stopped, and the operator adjusts the air bag 31, the non-woven fabric 40 and the PE film 50 back to the gantry 11 to remove the obstacle, and the heating device 20 can continue to operate the heating of the PE film 50. .

The above description is only a preferred embodiment of the present invention, and does not impose any form limitation on the present invention. Although the present invention has been disclosed above in the preferred embodiment, it is not intended to limit the present creation, and has any technical field. Usually the knowledge is beyond the scope of this creative technical solution.
