Horizontal type chain printing slotting machine, this press is also a manual paper, the use of the chain to push the board into the printing group printing mode.
Different from the previous direct printing machine, the slotting part can be added to make the printing slotting molding, and there is also a circular die cutting group.
The presses are most commonly used outside Guangdong, where they have increased in recent years because of labor costs. Why?
Because the combination of printing and slotting processes reduces at least one person, saves a lot of process time and correspondingly increases profits.
This model uses a lot of printing rubber, can also be affixed with double-sided adhesive printing plate on the board needed printing position, roll into the unit directly affixed to the plate roller printing, but only the first color.
If it is multi-color printing, the color group after the second color needs to be separated by the machine and pasted on the printing position, which is troublesome and takes a long time to adjust the machine. The skill requirement for the operator is quite high.
Cardboard is transverse into paper, mostly relatively long, the chain is fixed to push cardboard generally have three to four, if the cardboard is not in a straight line, the use of artificial paper, so the shortcomings are more obvious: cardboard into paper is easy to skew.
What are the consequences of skewing into the paper?
Printing content position is easy to move (printing overall position), not to mention the key is oblique, to the slotting group is bad, the depth of the left and right grooves is not the same, directly lead to the carton molding is not good, box height is skewed.
The die-cutting group requirements used in special-shaped cartons are mostly high, which increases the loss of cardboard. So this model with die – cutting group is very rare.
At the same time, it also increases the workload of nail box (adhesive box) after the process. If it is serious, it will not meet the requirements and be scrapped, and can only be sold as waste paper.
The speed of the boot must also be uniform, and the accuracy of the color printing is more normal within plus or minus 1MM.
The design speed of the machine is mostly about 80 sheets/minute, the structure of manual feeding, the speed is no use, people can not follow the speed of the machine.
So is there no way out?
The simple belt suction type automatic paper feeder comes into being. This model can synchronize with the printing press using the servo control system. The paper feed can change from manual single sheet feed to continuous feed.
Ensure that the cardboard is correct, not only improve the work efficiency, but also reduce the labor intensity of the workers, and reduce the rate of reject.
The disadvantage is that the curved single pit (corrugated) cardboard and E pit (corrugated) can not be smoothly sent out, not suitable for straight car models.
