Description

Technical Field

[0001] The utility model relates to the technical field of KT boards, in particular to a KT board which is convenient for secondary binding. Background Art

[0002] KT board is a new type of material made of polystyrene particles that are foamed to form a board core and then coated and pressed on the surface. The board is crisp, light, not easy to deteriorate, and easy to process. It is widely used in advertising displays and promotions. In advertising displays, a layer of printed advertising film is also attached to the surface of the KT board for display. A good kt board can not only effectively display advertising content, but also have a secondary use effect, which has met the needs of multiple uses of the KT board.

[0003] The KT boards on the market are generally installed in an edge-banding manner to protect the more fragile corners of the KT boards. The edge-banding protection method makes it impossible to fully utilize the KT board layout. At the same time, some KT boards that are not installed in an edge-banding manner may fall during use, causing their corners to bend easily, which makes the content expansion of the KT board uncomfortable for the viewer. For this reason, we propose a KT board that is easy to bind twice. Utility Model Content

[0004] The utility model aims to provide a KT board which is convenient for secondary binding, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a KT board that is convenient for secondary binding, including a board body, an edge board, a hot-melt edge and a knock-out hole, the board body is surrounded by edge boards retained by hot melting, the board body is a hexagonal column structure, and a plurality of board bodies are provided, the board bodies are hot-melt edges are formed by hot cutting, and a plurality of the board bodies are evenly arranged in sequence through the hot-melt edges to form a rectangular board, and a knock-out hole is formed in the middle of the rectangular board by knocking off a board body.

[0006] Furthermore, the board body comprises a friction adhesive layer and a polystyrene board core, and the friction adhesive layer is connected to both side surfaces of the polystyrene board core by glue.

[0007] Furthermore, the friction adhesive layer and the polystyrene core are bonded to form a plate of KT material, and the plate of KT material is cut into a plurality of plate bodies by a hexagonal mesh electric heating cutting knife.

[0008] Furthermore, the plurality of plates are extruded and hot-melted together to form a rectangular plate.

[0009] Furthermore, the plate body in the middle of the rectangular plate can be knocked off through the knock-out hole, and knocking off the plate body can fill the corners of the rectangular plate.

[0010] Compared with the prior art, the utility model has the following beneficial effects: when the KT board which is convenient for secondary binding is used, friction adhesive layers are arranged on both sides of the whole board body, and the side of the friction adhesive layer away from the polystyrene board core is of friction design, which satisfies the user to connect the printed advertising paper or film with the friction adhesive layer by pasting, and the side of the friction adhesive layer close to the polystyrene board core is a glue surface, ensuring that the polystyrene board core can be effectively protected by the friction adhesive layer.

[0011] The KT board is mainly cut into several board bodies by a hexagonal mesh electric hot cutting knife, and at the same time, the hot melt edges of several board bodies that have not been completely solidified are squeezed together by an extrusion device, so that the rectangular board composed of the several board bodies becomes a KT board.

[0012] The hexagonal columnar plate body can strengthen the hardness of the KT board, so that the KT board has good anti-deformation ability, meeting the needs of KT boards for large-scale printing and display, and the middle part of the KT board adopts a hollow design. When the KT board is damaged somewhere, the user can knock off the middle plate body to fill the damaged area around the KT board, thereby meeting the reuse needs of the KT board, and because the KT board is mainly a component for advertising printing paper or film support, there is no structural damage around the KT board, which does not affect the demand for advertising printing paper or film support, ensuring the rationality of the overall structure.
