Paperboard rotary die cutting machine and die cutting process

Abstract

The invention discloses a paperboard rotary die cutting machine and a die cutting process. A template is arranged on one side of an indentation roller I. Indentation molds are arranged on one side ofthe template. An indentation roller II is arranged on one side of the lower portion of the indentation roller I. A plurality of indentation knives are arranged on one side of the template and correspond to the indentation molds in position. A die cutting roller I is arranged on one side of the indentation roller I. One side of the outer portion of the die cutting roller I is sleeved with a rubbersleeve. A die cutting roller II is arranged on one side of the lower portion of the die cutting roller I. A template is arranged on one side of the die cutting roller II. Die cutting knives are arranged on the template. According to the paperboard rotary die cutting machine, indenting and die cutting are distributed on the different rollers, the indentation molds are arranged on the indentation rollers to enhance the paperboard forming effect, bending deformation of indentations on the outer portion of a formed carton is avoided, and the forming quality of cartons is improved.

Description

technical field [0001] The invention belongs to the technical field of cardboard die-cutting, in particular to a cardboard rotary die-cutting machine and a die-cutting process thereof. Background technique [0002] Die-cutting machines are generally used for cardboard processing and forming. Die-cutting machines are mainly divided into three types: round pressing, round pressing and flat pressing according to the different embossing forms; because the drum of the round pressing round die-cutting machine rotates continuously , so its production efficiency is the highest among all kinds of die-cutting machines; figure 1 , the existing die-cutting machine generally integrates the creasing and trimming on the roller II2, and the plastic layer 24 is set on the roller I1, and the motor 7 drives the roller I1 and the roller II2 to rotate through the reducer 8, and the creasing The knife 11 realizes the indentation die-cutting process of the cardboard 21. At the same time, the die-...

[0002] Die-cutting machines are generally used for cardboard processing and forming. Die-cutting machines are mainly divided into three types: round pressing, round pressing and flat pressing according to the different embossing forms; because the drum of the round pressing round die-cutting machine rotates continuously , so its production efficiency is the highest among all kinds of die-cutting machines; figure 1 , the existing die-cutting machine generally integrates the creasing and trimming on the roller II2, and the plastic layer 24 is set on the roller I1, and the motor 7 drives the roller I1 and the roller II2 to rotate through the reducer 8, and the creasing The knife 11 realizes the indentation die-cutting process of the cardboard 21. At the same time, the die-cutting knife 12 has a certain amount of cutting into the plastic layer 24, which can protect the die-cutting knife 12 and ensure complete cutting, but the plastic layer needs to be replaced regularly 24. It not only increases the production cost of the enterprise, but the frequent replacement of the plastic layer 24 also reduces the forming efficiency of the cardboard; in order to solve this problem, the technicians replace the plastic layer 24 with the rubber sleeve 6, so that the rubber sleeve 6 is set on the roller outside the cylinder, and regularly move the position of the rubber sleeve 6 to change the cutting marks of the die cutter 12, avoiding frequent replacement of the plastic layer 24; The creasing knife can only indent one side of the cardboard. When the cardboard is folded and formed, the other side of the cardboard has no indentation or indentation is easy to produce bending deformation, which will affect the quality of the carton.
