With the rapid development of the modern logistics industry, the design of logistics packaging boxes has gradually been valued by the industry. Its processing technology, structure, materials, etc. not only affect the cost and efficiency of manufacturers, but also affect the user's experience.

In the past, logistics packaging boxes were mostly made of wood boards, but in recent years, with the rise of wood prices and the international trend of protecting the ecological environment, the industry has gradually abandoned this material, and most of the small and medium-sized logistics packaging boxes It is made of corrugated cardboard, and the technology is becoming more and more mature.

The existing corrugated cardboard packaging structure usually consists of a fixed cardboard box and an external buffer. The fixed box includes two end plates and a cylinder, which is generally composed of four side panels with glue. Or nail fixed connection, usually in a square shape, and the four side panels are all made of corrugated cardboard. However, when this corrugated cardboard is used, its paper material is susceptible to moisture and mildew, and its strength is also poor, so some industries use plastic hollow boards to replace it. Although the plastic hollow board solves the above-mentioned problems of corrugated cardboard, its own structure determines that it still has the problems of uneven force in all directions and orientation of strength, so it is now replaced by plastic honeycomb board, but plastic When the honeycomb panel is being processed, it is necessary to cut the plate, so there are the following problems: after cutting, the cutting edge of the plate is in an open state. The hidden danger of cutting the hands of the plate in the open state is one of the hidden dangers; the second is that when the plate in the open state is used for a long time, the upper and lower plate surfaces will collide with the rib structure between the two plate surfaces. The tissue is detached, which affects the quality of the product; third, the trimming of the plate in the open state will accumulate dust after long-term use, which will affect the overall appearance of the packaging box.

Therefore, how to solve the above problems becomes the problem to be solved by the present invention.
