detailed description

The present invention will be further described below through specific embodiments. The following examples are preferred implementation forms of the present invention, but the implementation manners of the present invention are not limited by the following examples.

As shown in Figure 1, a kind of edge banding device of thermoplastic honeycomb panel comprises workbench 1, and the two ends of described workbench are respectively provided with mold support 2, is provided with hot mold 4 and cold mold 5 on mold support 2 , the mold support 2 is connected with a linear drive mechanism 3 for driving the movement of the mold support 2 .

The hot mold 4 and the cold mold 5 are arranged up and down, the mold support 2 is provided with a bottom plate that can move up and down, the hot mold 4 and the cold mold 5 are fixedly connected to the bottom plate by screws, and the hot mold 4 and the cold mold The mold 5 has arc grooves adapted to the thickness of the thermoplastic honeycomb panel 8, and the radian of the arc groove can be designed according to the specific requirements of the thermoplastic honeycomb panel.

A linear drive mechanism 3 for driving the mold support 2 to move is connected to the mold support 2, and the linear drive mechanism 3 can be an air cylinder, an oil cylinder or a servo motor with a ball screw. A clamping device 6 for fixing the thermoplastic honeycomb panel 8 is provided on the workbench 1 to prevent the thermoplastic honeycomb panel from moving perpendicular to the advancing direction during the pressurization process.
