Description

Corrugated board packaging box

Technical Field

The utility model relates to the technical field of casting packaging boxes, in particular to a corrugated board packaging box.

Background

The castings are metal molded articles obtained by various casting methods, are often used as machine part blanks or directly used as parts of machines, have a wide application range, and are transported to various places for assembly or reprocessing after being completed in order to meet the production of various mechanical products.

Because the casting is heavy, in order to ensure stability and safety, the wooden packing box is generally adopted for packing and transporting during transportation, but the wooden packing box has high manufacturing cost and low recycling rate, and the transportation cost is high. And generally, the wooden packing box is transported in large batch, the wooden packing box cannot be folded, the loading capacity is less during transportation, the number of the used packing boxes is more, the occupied area of the wooden packing box is larger, a large-area warehouse is occupied, and the transportation efficiency is lower.

Therefore, in order to improve the transportation efficiency and reduce the transportation cost, it is necessary to provide a corrugated board packaging box.

Disclosure of utility model

The utility model aims to provide a corrugated board packing box, which is used for simplifying the structure of a foot protection board, facilitating installation and maintenance, improving the strength of the foot protection board, enabling the foot protection board to be more flexible to open and close, improving the running stability and reliability and reducing the production cost.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

The utility model mainly provides a corrugated board packing box which is low in cost, green, easy to recycle and easy to store, and can be used for containing 4 castings, about 1000Kg and overlapping on the premise of ensuring the packing and transporting quality, so that one container is ensured to be fully loaded as much as possible; and can ensure that the castings cannot be bruised in the transportation process. The warehouse utilization rate is improved, and the customer satisfaction is improved. The corrugated board packaging box comprises a tray made of plywood, wherein a lower cover made of corrugated paper is arranged on the tray, a coaming made of corrugated paper is arranged on the lower cover, and an upper cover made of corrugated paper is arranged on the coaming; a pressing plate assembly is movably arranged in the coaming, and the pressing plate assembly comprises 2 pairs of corrugated boards which are oppositely arranged; the corrugated board is of a cuboid structure, the length of the corrugated board is 950-1000mm, the width of the corrugated board is 110-150mm, the thickness of the corrugated board is 20-40mm, a limiting groove and a plurality of clamping grooves are further formed in the corrugated board, and 2 pairs of corrugated boards are sequentially connected into a square structure through the clamping grooves.

The principle and the advantages of the scheme are as follows:

Because the casting is heavy, the transportation amount is also large, and in order to ensure the transportation quality and safety, reliable and stable wooden packing boxes can be selected for packaging and transportation, and the paper package can be considered to be easily damaged and cannot be pressed and wetted for the heavy objects. But wooden packing box structure is fixed, can not fold, leads to wooden packing box occupation space big, and the volume of loading just becomes less, and wooden packing box itself manufacturing cost is higher, still is difficult for retrieving and recycle, makes it occupy the storehouse space of large tracts of land, further increases manufacturing cost.

The corrugated board is adopted as the packing box, the tray of the plywood is arranged at the bottom of the packing box so as to play a role in fixing and supporting, corrugated boards are adopted at other positions of the packing box, and reasonable selection is carried out on the material, the edge and the thickness of the boards, so that the stability of the corrugated board packing box is ensured, and the transportation quality requirement of castings is met. Through the combination of tray and corrugated container board, even if the transportation reaches the requirement, can effectively reduce package transportation cost again, and also can retrieve the recycle to corrugated container board part, do not occupy the storehouse space. The designed packaging box can be placed in an overlapping way after being loaded with castings, and the pressing plate combination and the coaming bear 1000Kg of weight above the packaging box during the overlapping; the pressing plate combination simultaneously limits the castings, avoids the castings from damaging in the transportation process, and ensures the transportation quality.
