Column-to-column die cutting machine for corrugated board

Abstract

The invention relates to the technical field of corrugated board processing, in particular to a column-to-column die cutting machine for a corrugated board. The column-to-column die cutting machine comprises a die cutting wheel set, a conveying belt, a charging device and a control unit, wherein the die cutting wheel set is composed of a die cutting wheel and a pressure wheel, the die cutting wheel set and the conveying belt are in linkage through a gear set, the discharging end of the conveying belt is close to the feeding inlet side of the die cutting wheel set, the charging device is located at the end, far from the die cutting wheel set, of the conveying belt, and the control unit is used for controlling the column-to-column die cutting machine for the corrugated board to work,. The peripheral line speeds of the die cutting wheel and the pressure wheel are the same as the conveying speed of the conveying belt. The length L of the conveying face of the conveying belt, the radius R of the die cutting wheel and the length B of a die cutter in the circumferential direction of the die cutting wheel has the relation of L=N*2 pi R-B, wherein N is a nonzero natural number, and pi is the circumference-diameter ratio. The feeding time can be strictly controlled, thus a feeding point is accurately matched with a working point of the die cutter, and the product quality is improved.

Description

technical field [0001] The invention relates to the field of corrugated cardboard processing, in particular to a corrugated cardboard rotary die-cutting machine. Background technique [0002] Corrugated cardboard is widely used in the packaging industry due to its simple production process and low cost. At present, in the process of mass processing of corrugated cardboard, rotary die-cutting machines are generally used. The pressure wheel and the die-cutting wheel of the rotary die-cutting machine need to rotate synchronously, and when feeding the working wheel group composed of the pressure wheel and the die-cutting wheel, the feeding timing must be grasped very well, premature feeding or Late feeding will cause the working wheel group to run idly or semi-idly, which will lead to incomplete processing of corrugated cardboard, or even no processing at all, and even damage the corrugated cardboard in severe cases. The current solutions generally combine complex control syst...
