The easy movement of the content of the printed product (the overall movement of the printing) is not to be mentioned. The more important thing is that it is oblique. It is bad when it reaches the slotting group. Askew. Printing machinery
The requirements for the die-cutting group used in special-shaped cartons are mostly high, which increases the loss of cardboard. Therefore, it is rare for this model to have a die-cutting group.
At the same time, it also increases the workload of the post-process nail box (gluing box). In serious cases, it will be scrapped because it cannot meet the requirements, and it can only be sold as waste paper.
The speed of the boot must also be uniform, and the accuracy of register printing is within plus or minus 1MM is relatively normal.
The design speed of the machine is mostly about 80 sheets/minute. The structure of manual feeding, no matter how fast the speed is, it is useless. People are following the speed of the machine.
So is there no way?
Simple belt suction type automatic paper feeder came into being, this model can be synchronized with the printing press using the servo control system, and the paper feeding can be changed from manual single-sheet feeding to continuous feeding Paper.
Ensure that the cardboard is straight, not only improves work efficiency, but also reduces the labor intensity of workers and reduces the waste rate.
The disadvantage is that the more curved single-pit (corrugated) cardboard and E-pit (corrugated) cannot be sent out smoothly, and are not suitable for adding * straight car models.
