Multiple pre-pressing and indentation grooving machine for corrugated paper

Abstract

The invention discloses a multiple pre-pressing and indentation grooving machine for corrugated paper. The multiple pre-pressing and indentation grooving machine for the corrugated paper comprises a pre-pressing grooving portion and an indentation grooving portion which are installed on a machine frame. The pre-pressing grooving portion comprises a first pre-pressing wheel set, a second pre-pressing wheel set and a first grooving wheel set through which the corrugated paper passes sequentially. The indentation grooving portion comprises a first indentation wheel set, a second indentation wheelset and a second grooving wheel set. The output end of the first grooving wheel set is connected with the input end of the first indentation wheel set. The corrugated paper is subjected to multiple pre-pressing and indentation procedures including primary pre-pressing, secondary pre-pressing, primary grooving, primary indentation, secondary indentation and secondary grooving. The pressing amountsof all the wheel sets increase step by step through step-by-step progressive pressing, and therefore the problem that the indentation position breaks due to one time or two times of pre-pressing in the prior art is eliminated.

Description

technical field [0001] The invention relates to the technical field of carton packaging machinery, in particular to a corrugated paper multiple pre-pressing creasing and slotting machine. Background technique [0002] In the process of corrugated box manufacturing, the cardboard after the printing process needs to be processed in subsequent processes such as creasing, slotting, trimming, and corner cutting. Among them, corrugated cartons must be folded into cartons, and the folds must be crimped. Whether the setting of the creasing device is reasonable or not directly affects the forming quality of corrugated boxes. If the creasing and scoring lines are not suitable, when the folding carton is formed, the cardboard will not be folded along the creasing line, and folding deviation will occur, making it difficult to form a box; at the same time, the existing Crimping usually uses a set of crimping devices, without multiple pre-pressing, the distance between the creasing wheel...

Problems solved by technology

Whether the setting of the creasing device is reasonable or not directly affects the forming quality of corrugated boxes. If the creasing and scoring lines are not suitable, when the folding carton is formed, the cardboard will not be folded along the creasing line, and folding deviation will occur, making it difficult to form a box; at the same time, the existing Crimping usually uses a set of crimping devices, without multiple pre-pressing, the distance between the creasing wheels cannot be adjusted automatically, resulting in easy bursting of corrugated paper creasing and scoring lines, resulting in waste of cartons, wasting manpower and material resources, causing rising cost
