How to choose the width of the circular press die-cutting machine when the customer is selecting it

The selection of width must match the printing machine and stamping machine. Cigarette packaging printing enterprises adopt two standards in terms of width: 650mm and 820mm. However, due to the low efficiency of the 650mm width, in recent years, the printing and stamping machines newly purchased by enterprises have chosen the 820mm width, which is also the horizontal layout of 3 small boxes or 2 strip box cigarette packs on the printing plate roller (note: the outer dimensions of hard packaged small box cigarette packs are about 245mm long and 98mm wide; the outer dimensions of strip box cigarette packs are about 375mm long and 295mm wide, and the specific dimensions are determined by the cigarette packaging machine).

Due to the inconsistent fiber orientation of the paper in China, Europe, and other countries, cigarette packaging printing can only be arranged horizontally, and vertical layout is not allowed. Therefore, the layout method of small box cigarette packaging on the die-cutting knife roller is generally horizontal three vertical eight or horizontal three vertical ten; The layout method of the cigarette pack on the die cutting knife roller is generally horizontal two vertical three or horizontal two vertical four. The principle of circular die-cutting is that the upper axis blade separates the paper from the lower axis roller, and the thickness of the die-cutting blade roller should be appropriate, that is, the circumferential layout of the die-cutting blade should not be less or more. When the circumferential layout of the small box is less than 8 pieces and the strip box is less than 3 pieces, the die-cutting knife roller is too thin, and the axial end roller pillow is pressurized during use, which can cause deformation of the die-cutting roller and result in inability to cut in the middle; When the circumferential layout of the small box is more than 10 pieces and the strip box is more than 4 pieces, the die cutting roller is too thick, which will increase the manufacturing cost and be uneconomical.
