Description

TECHNICAL FIELD

[0002] Luggage bearing plates are a crucial component in the design and manufacturing process of modern luggage, aimed at providing structural strength and support to ensure durability and stability during transportation and use. With the acceleration of globalization and the diversification of travel methods, consumers' demands for luggage are constantly increasing, and the design and materials of bearing plates have also developed.

[0003] The material selection of bearing plates is a key factor affecting their performance. In luggage, the design of bearing plates usually adopts a multi-layer structure, with the core material in the middle being a honeycomb paperboard. This honeycomb paperboard, due to its lightweight and relatively high strength characteristics, has become an ideal choice for bearing plates. The upper and lower surfaces of the honeycomb paperboard are placed with glass fiber layers and sprayed thermosetting materials, respectively, and finally molded together in a hot press.

[0004] Currently, the process of placing glass fiber layers and spraying thermosetting materials on the honeycomb paperboard requires manual operation. After the worker lays the glass fiber layer on the honeycomb paperboard, he uses a spray gun to spray the thermosetting material, then turns over the honeycomb paperboard, lays the glass fiber layer on the other side, and uses the spray gun to spray the thermosetting material. Then the honeycomb paperboard is placed in the hot press for molding. This process requires two workers, one to lay the glass fiber layer and operate the spray gun, and the other to operate the hot press. The degree of automation is low, and the labor consumption is large, so the product line needs to be improved. INVENTION CONTENTS
