Technical Field

The utility model relates to a paper tray technical field especially relates to a waterproof type honeycomb panel paper tray.

Background

The trays used in the existing logistics storage and transportation are generally made of wood, plastic and metal materials. Plastic pallets are restricted or forbidden due to environmental requirements, especially in export shipping packages; the metal tray can only be used in some special occasions due to the high manufacturing cost and the limitation that the weight of the metal tray is several times higher than that of other trays; wooden tray belongs to wooden packing field, if export need pass through strict quarantine and fumigation, and it is long and comparatively complicated consuming time, simultaneously, also contradict with the basic policy of the protection forest of country.

At present, there are a large number of trays prepared by adopting honeycomb plates as core layers on the market, but the raw material corrugated paper prepared by the trays is weaker in waterproof performance and can seriously affect the strength after moisture absorption, therefore, in order to solve the problem that the strength of the paper tray is reduced after moisture absorption, the Chinese patent No. CN201310495729.6 discloses a high-strength waterproof honeycomb paper tray, which comprises a honeycomb plate and supporting blocks, wherein the supporting blocks are respectively and evenly arranged on four edges of the bottom surface of the honeycomb plate at intervals, protective plates are respectively arranged on the side walls of four sides of the honeycomb plate, and waterproof layers are respectively arranged on the surfaces of the honeycomb plate, the supporting blocks and the protective plates.

Above-mentioned patent is through installing the backplate on the curb plate of honeycomb panel to at the surface coating waterproof layer of backplate, supporting shoe and honeycomb panel, foretell honeycomb paper tray undoubtedly can the greatly increased paper tray's the processing degree of difficulty, greatly increased paper tray's processing cost.

SUMMERY OF THE UTILITY MODEL

The present invention aims at solving at least one of the technical problems in the related art to a certain extent. Therefore, an object of the utility model is to provide a waterproof type honeycomb board paper tray, honeycomb cardboard and upper and lower face composite paper (board) all adopt two-sided waterproof paper materials to make, greatly reduced paper materials cost, also be convenient for processing preparation simultaneously.

The technical scheme of the utility model as follows:

a waterproof honeycomb board paper tray comprises a honeycomb core layer, a surface board and a bottom board, wherein the surface board and the bottom board are respectively compounded at the top and the bottom of the honeycomb core layer, and the surface board, the honeycomb core layer and the bottom board are all made of double-sided (can be made of) waterproof paper materials.

Further, the surface layer plate, the honeycomb core layer and the bottom layer plate adopt commercially available double-sided sizing kraft paper with the gram weight of 100-300g/m²。

Furthermore, the honeycomb core layer is formed by gluing and compounding a plurality of paper units in pairs.

Furthermore, the honeycomb core layer is formed by compounding 4-8 paper units in pairs.

Furthermore, each paper unit is provided with bonding surfaces extending in the longitudinal direction of the paper at equal intervals, and adhesive glue is symmetrically arranged on two end sides of each bonding surface.

The utility model has the advantages that: the surface plate, the honeycomb core layer and the bottom plate are made of double-sided waterproof paper materials, do not absorb water, and compared with the traditional corrugated paper honeycomb paperboard, the side surface of the corrugated paper honeycomb paperboard can achieve better moisture resistance without adopting a special waterproof process or a waterproof coating structure, so that higher bearing capacity can be kept for a long time, the processing is simpler, and the corrugated paper honeycomb paperboard is similar to the traditional corrugated paper honeycomb paperboard, so that the subsequent waterproof treatment can be omitted, and the cost is reduced; through being provided with two sets of adhesive glues on the both ends side of bonding face, can make two liang of compound and tensile honeycomb cardboard of each paper unit after, the hexagon of honeycomb cardboard section is comparatively regular, can not lead to the edge dislocation of the hexagon of adhesion not to be regular hexagon like the coating rubberizing that conventional roller coat caused inhomogeneous, and the adhesion face also loosens easily simultaneously and drops, leads to the bearing capacity of honeycomb panel to receive the restriction.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

Referring to fig. 1, a waterproof honeycomb board paper tray comprises a honeycomb core layer 2, a surface board 1 and a bottom board 3 which are respectively (glued) compounded at the top and the bottom of the honeycomb core layer 2, wherein the surface board 1, the honeycomb core layer 2 and the bottom board 3 are all made of double-sided waterproof (can be made of) paper, in the implementation, commercially available double-sided sizing kraft paper is adopted, and the gram weight is 100-²。
