Corrugated board grooving machine

Abstract

The invention discloses a slotting machine for corrugated cardboard, which comprises a pre-pressing slotting part and a line-pressing slotting part installed on a machine frame. The pre-pressing slotting part includes a first pre-pressing wheel set, a second The pre-pressing wheel set and the first grooving wheel set, the creasing and grooving part includes the first creasing wheel set, the second creasing wheel set and the second grooving wheel set, the output end of the first grooving wheel set is connected to the second A crimping wheel set is connected to the input end. The corrugated paper has passed multiple pre-pressing and creasing processes such as "first pre-pressing-second pre-pressing-first slotting-first crimping-second crimping-second slotting", Through step-by-step pressing down, each wheel set gradually increases the amount of pressing down, thereby eliminating the problem of bursting at the pressing line caused by one or two pre-pressings in the prior art.

Description

technical field [0001] The invention relates to the technical field of carton packaging machinery, in particular to a slotting machine for corrugated cardboard. 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 wheels cannot be adjusted automa...

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
