The pallet surface and the pallet foot are both composed of paper strips of uniform structural material. The paper strips are corrugated cardboards composed of several layers of vertically erected paper. The outer layers of the corrugated cardboard are respectively fixed and connected. Cardboard composed of several layers of paper, with kraft paper for edge wrapping on the outer layer of the cardboard. Patent No. 200720068569.7 is a utility model for a paper pallet, which includes a top board, a transverse leg assembly and a longitudinal leg assembly. The transverse leg assembly and the longitudinal leg assembly are respectively provided with a number of matching engaging grooves.

Contents of the invention

The purpose of this utility model is to provide a kind of composite paper made of kraft wax paper, anti-static veneer kraft paper, yellow cardboard, grass cardboard, corrugated cardboard and other paper materials, which has high hardness, waterproof, no deformation, no mildew and light weight. , Degradable composite paper tray.

The above-mentioned technical problems of the utility model are mainly solved by the following technical solutions: the composite paper tray includes a panel, a bottom plate, and a column, wherein the column is a hollow tube structure, and its thickness matches the design model of the tray. The relative position of the column is provided with a boss, and the outer diameter of the boss is an interference fit with the inner hole of the column. The assembly form of the panel and the column can be the assembly form of the bottom plate and the column, which is easy to assemble, has good strength, saves materials and is light in weight.

Preferably, the bottom plate is provided with several, such as three, and each bottom plate is provided with several bosses, such as three bosses, which cooperate with the uprights to jointly support the designed bearing load of the tray.

As a preference, the bottom plate is arranged in one piece, which is consistent with the size of the panel, and several bosses are arranged on the bottom plate, such as three rows, three in each row, nine in total.

Preferably, the circumferential surface of the boss is a rough surface, because this structure requires an interference fit between the boss and the column, and the rough surface provides a tighter assembly method, which can be properly glued Mixture, also can not glue.

As a preference, the panel is provided with a convex step at the relative position of the assembly column, and the outer diameter of the convex step is in interference fit with the inner diameter of the column. This is an embodiment of the utility model. The assembly method of the panel and the column The assembly method is the same as that of the bottom plate and the column. Of course, some glue can be applied to increase the overall structural strength.

As a preference, the panel is provided with a counterbore at the relative position of the assembling column, and the diameter of the counterbore is an interference fit with the outer diameter of the column. This is another embodiment of the present invention. If the counterbore form is adopted, then The upper plane where the column contacts the panel can be sealed to increase the contact area between the column and the panel.

As a preference, in the panel and bottom plate composite process of the present invention, the outer layer is provided with face paper, the second layer is provided with a reinforcement board, and the middle layer is provided with composite multi-layer corrugated paper, wherein the face paper adopts kraft wax paper or anti-static veneer kraft paper to strengthen The board is superimposed with multi-layer yellow cardboard and straw board paper, and the composite multi-layer corrugated paper is made of cross-superimposed and glued multi-layer single-sided corrugated paper.

Therefore, the utility model is a composite paper tray with reasonable structural design, convenient assembly, high hardness, waterproof, no deformation, no mildew, light weight and degradability.
