[0029] The power box 57 and the wire are electrically connected to the external power supply, and then the wire is electrically connected to the guide column on the upper surface of the heating plate 554, and then the heating plate 554 is set before work to perform heating treatment, and then the heat is transferred to the heat-conducting roller 55 through the action of the horizontal block 551 and the vertical block 552, so that the surface of the heat-conducting roller 55 becomes hot. When the conveying device 1 is started and the veneer is covered on the door panel, the veneer covered on the door panel is squeezed, rolled and compacted by the action of the heat-conducting roller 55, and the veneer and the door panel are heated due to the heating of the surface when the heat-conducting roller 55 is squeezed and rolled. The glue between them is dried once, and the spring 56 is set so that the heat-conducting roller 55 and the veneer are tightly fitted and compacted. At the same time, the spring 56, the vertical plate 52, the slide groove 53, and the slider 54 cooperate with each other to adapt to different types of door panel thicknesses.

[0032] The following is a detailed description of the working principle of the surface veneer equipment for fire door production.

[0033] Before use, the power box 57, the guide column, and the heating plate 554 are set to perform heating treatment, and then the heat is transferred to the heat-conducting roller 55 through the action of the horizontal block 551 and the vertical block 552, so that the surface of the heat-conducting roller 55 becomes hot. When the conveying device 1 is started, the door panel is placed on the conveyor belt, and the glue spraying head 3 starts to spray glue, thereby driving the door panel to move slowly. When the door panel moves to the appropriate position, the veneer wrapped by the reel 44 is loosened, so that the loosened veneer contacts the door panel, so that the position of the first half of the door panel is fitted with the veneer, so that the glue and the veneer are bonded. When the door panel moves in the conveying device 1, The skin is driven to loosen and rotate on the surface of the roll 44, thereby driving the roll 44 to rotate on the outer surface of the connecting shaft 43 and cover the door panel. After covering, the skin on the door panel is separated from the skin on the roll 44 by workers' cutting. When the door panel moves again, it contacts the heat-conducting roller 55, and the spring 56 is set to tightly press the heat-conducting roller 55 and perform a drying process at the same time. Then, the heating plate 554 is used to perform secondary heating, and the heating plate 554 is close to the covered skin to prevent excessive heat dissipation and thus perform secondary drying.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
