Honeycomb paperboard composite gluing device, gluing method and honeycomb board and honeycomb paperboard tray prepared by using honeycomb paperboard composite gluing device

Abstract

The invention discloses a honeycomb paperboard composite gluing device, a gluing method and a honeycomb board and a honeycomb paperboard tray prepared by using the device. The honeycomb paperboard composite gluing device comprises a glue spraying pipe with two through ends; a plurality of groups of paired glue spraying holes are arranged on the glue spraying pipe at equal intervals; one end of the glue spraying pipe is connected with a glue inlet joint for glue inlet of an external glue pipe; and the other end of the glue spraying pipe is connected with an end socket for plugging. According to the honeycomb paperboard composite gluing device provided by the invention, a glue spraying mode is adopted, gluing is uniform, positioning is convenient, and the glue spraying accuracy can be guaranteed; and the honeycomb paperboard, an upper composite paper (board) and a lower composite paper (board) are all made of double-sided Cobb paper, so that the paper cost is greatly reduced, and meanwhile, the processing and the preparation are convenient.

Description

technical field [0001] The invention relates to the technical field of paper trays, in particular to a composite gluing device for honeycomb paperboard, a gluing method, and a honeycomb board and a honeycomb paperboard tray prepared by using the device. Background technique [0002] The pallets used in the existing logistics storage and transportation are generally made of wood, plastic and metal materials. Plastic pallets are restricted or banned due to environmental requirements, especially in export transport packaging, and are strictly prohibited; metal pallets can only be used for certain types of pallets because of their high cost and weight several times higher than other pallets. For some special occasions; and wooden pallets belong to the field of wooden packaging. If they are exported, they need to go through strict quarantine and fumigation, which is time-consuming and complicated. At the same time, it is also contrary to the basic policy of the country to protect...

Problems solved by technology

Plastic pallets are restricted or banned due to environmental requirements, especially in export transport packaging, and are strictly prohibited; metal pallets can only be used for certain types of pallets because of their high cost and weight several times higher than other pallets. For some special occasions; and wooden pallets belong to the field of wooden packaging. If they are exported, they need to go through strict quarantine and fumigation, which is time-consuming and complicated. At the same time, it is also contrary to the basic policy of the country to protect forests.

[0003] At present, there are a large number of trays prepared with honeycomb panels as the core layer in the market, but the corrugated paper made of raw materials has weak waterproof performance, and the strength will be seriously affected after moisture absorption. No. CN201310495729.6 discloses a high-strength waterproof honeycomb paper tray, including honeycomb boards and support blocks, and support blocks are installed at even intervals along the four sides of the bottom surface of the honeycomb board, and on the four sides of the honeycomb board Guard plates are respectively installed on the walls, and waterproof layers are respectively arranged on the surfaces of the honeycomb panels, support blocks and guard plates

[0004] The above-mentioned patent installs the protective plate on the side plate of the honeycomb panel, and coats the waterproof layer on the surface of the protective plate, support block and honeycomb panel. The above-mentioned honeycomb paper tray will undoubtedly greatly increase the processing difficulty of the paper tray and greatly increase the paper tray. processing cost

[0005] In addition, at present, most of the industry adopts the method of roller coating to glue the base paper to be processed, but because the method of rubber roller gluing belongs to the secondary transfer gluing, it will cause uneven gluing, and then make the base paper of the honeycomb paperboard composite. After that, local degumming or dislocation will occur, which will cause dislocation and deformation of the hexagon of the honeycomb paperboard prepared later, which will affect the load bearing.
