Description

TECHNICAL FIELD

[0001] The utility model relates to paperboard indentation equipment technical field especially relates to a transverse pressure cutter structure of corrugated paperboard indentation machine. BACKGROUND

[0002] Carton is the most widely used packaging product, and the packaging carton is an indispensable part of modern logistics. Commonly used packaging cartons mainly adopt corrugated cartons and single-layer paperboard cartons. Both corrugated cartons and single-layer paperboard cartons are composed of box shapes by folding and bonding after cutting and indentation of paperboard.

[0003] Corrugated paperboard is a board composed of corrugated core layers and cover layers formed between two or more paperboards. The corrugated core layers are corrugated, and the corrugated corrugations are connected in sequence and support each other to form a triangular structure, which has good mechanical strength and can withstand a certain pressure from the plane. The existing corrugated paperboard is mostly indented by indentation equipment on the surface of the paperboard to form folding marks on the surface of the corrugated paperboard, which is convenient for subsequent folding to form cartons. In the indentation process, a pressure cutter is used to perform longitudinal indentation and transverse indentation on the surface of the corrugated paperboard. Since the corrugated corrugations of the corrugated paperboard are concave at the adjacent positions, the supportability is weak, and when the corrugated paperboard is transversely indented, the paperboard is prone to breakage, which affects the indentation effect of the paperboard.

[0004] Referring to the patent publication number "CN221366046U", the patent name "A carton indentation device", the technical scheme discloses "A carton indentation device, a support is installed on an operation table, a gas cylinder is installed on the support, a mounting seat is installed on the gas cylinder, a hollow indentation cutter is installed at the bottom of the mounting seat, a wet water structure is arranged in the hollow indentation cutter, the wet water structure is installed on the support, a positioning structure is arranged on the operation table, and the positioning structure is matched with the hollow indentation cutter; the utility model, through the setting of the wet water structure, when the paperboard is creased, the electromagnetic valve is opened, the water in the water tank flows into the buffer water box, so that the sponge can absorb water, then the gas cylinder is started, the gas cylinder drives the hollow indentation cutter to slide downward, the sponge will first contact the paperboard to moisten the paperboard, reduce the dryness of the surface, then the hollow indentation cutter continues to slide downward, the buffer water box and the sponge are squeezed into the hollow indentation cutter", although the technical scheme can indent the wet paperboard by the hollow indentation cutter, which can avoid the cracking of the paperboard during indentation and improve the processing quality, but the technical scheme cannot effectively realize the uniform pre-pressing action and indentation action on the corrugated paperboard, which affects the production quality of the carton.
