Background

Slit paper is a structural paper for packaging, and a die cutter cuts kraft paper by rotary rolling into slit-like paper that is engraved in a transverse and longitudinal array, with opposite ends of the paper extending parallel and in a row of slits forming a row of openings, and the paper is expandable. The opening unit is functionally connected to the inclined platform when the die-cut paper is extended by tearing, thereby enhancing the elasticity of the expanded paper and enhancing the cushioning protection of the article when the article is wrapped with such expanded paper.

A rotary die cutting apparatus (also known as a slot machine) is known which includes a paper supply spool and web tensioning guide which control the paper path from side to facilitate die cutting, a die cutting station where a rotary die of a knife cooperates with a hard anvil to produce the desired cut pattern. The rotary die may be driven by a conventional power source and may be belt driven or driven by gear teeth. The slit paper is then wound onto a rewind roll.

However, since the conventional rotary die-cutting machine is generally provided with a rotary die and a hard anvil which are engaged with each other during cutting operation, the tension of the raw paper entering the rotary die and the hard anvil is unstable and the raw paper is liable to wrinkle and deform.

In the existing rotary die cutting equipment (slit paper production equipment), a paper roll is loose on a feeding roller, the paper roll rotates along with a shaft, tension is insufficient, the problem that the paper roll is loose is that the kraft paper deviates left and right in the conveying process, so that the kraft paper is not aligned with a roller cutter when entering a die cutting mechanism, the cut paper is not flat, and the problem that the end surfaces of two ends of the stock paper in a winding mechanism are not parallel and level is caused; in addition, when the kraft paper of the emptying mechanism is not used up, paper splicing is sometimes needed, generally, the paper is spliced by manually gluing the paper with glue, the two ends of the kraft paper of the paper splicing are free ends, the direction is not fixed, and the paper splicing is difficult.

The tension of rolling is not constant when the existing production equipment rolls, and paper can also be loose and untight when rolling.
