Choosing the right parting machine and cutting machine

In the corrugated board production line, the dried corrugated board is pressed, cut and cut according to the requirements and specifications of the carton making, and becomes a single corrugated cardboard. Choosing the right paper-separation press and cutting machine can improve the cutting precision of the paper blank and increase the production efficiency, and reduce the waste of the paperboard.

Double group paper separator

The double-group paper separation press consists of a set of press-line mechanisms and a set of paper mechanisms. In order to meet the requirements of specification changes and continuous production, often a two- or three-component paper pressure line device is installed on a sheet-separation machine. When one group is working, the other is based on the specifications of the next batch of cartons. Adjust the cutting knife and press the track, so that the specifications do not stop conversion.

Figure 3 is a component cutter, with the upper and lower knifes splitting the cardboard. The slitting knife can move in the axial direction, two sets of trimming, and the middle knife cuts. The cut edge of the paper is removed by a straw. The overlap between the upper and the lower is 1/2 of the cardboard thickness t plus 1mm. The linear speed of the cutting edge is 10%-20% faster than that of the corrugated cardboard to ensure that the incision is smooth and flat. However, many of the disadvantages of this dual-segment separation press line are the tendency to press the edge of the paperboard, crumpling, and delaminating the board. So thin knife cutting machine appeared.

Thin knife cutting machine

The thin knife slitting machine is a relatively advanced paper separating device developed and produced in recent years. The thin knife slitting paper board uses a high-speed driven single knife to cut the cardboard at a specified position on the corrugated board production line. The blade knife is embedded in the slotted pallet at the bottom, and the pallet supports the corrugated cardboard during the slitting, as shown in FIG. 4 . The blade knife slitting tool transmission system is independent of the indentation device transmission. When the indentation roller runs at 2%-3% of the speed of the large cardboard, the blade knife is larger than the cardboard speed by 300% to 500%.

Thin knife cutting machine can improve the cutting accuracy of paper blanks, cutting edges beautiful, and conducive to the full version of the carton printing. Therefore, the choice of thin knife slitting machine can improve product quality and increase production efficiency.
