Carton printing equipment purchase precautions
For carton printing equipment, accuracy is an important indicator, which is mainly determined by the nature of the Corrugated Box
produced by the company. What aspects of precision do you have?
Many bosses pay more attention to the accuracy of printing overprinting when purchasing equipment. There is nothing wrong with this, but the accuracy of paper feeding, the accuracy of the position before and after slotting, and the accuracy of the position before and after die cutting are also the advantages and disadvantages of constant equipment. Important indicators. Let's talk about it separately.
1. Paper feeding accuracy China Sourcing agent for Printing machine
The accuracy of the position before and after feeding is directly related to the accuracy of the position of the printed content.
The accuracy error of paper-type printing equipment feeding is large, what is the reason?
The paper feeding method of this type of machine relies on manual work. The difference in the size of the paper causes the strength of the paper to be different, and the strength of each piece of paper placed is different.
There is one more important factor: the speed of the machine. The faster the machine speed, the greater the force of pushing the paper and the different running positions.
So the skill of the operator is critical.

It is normal to control the accuracy of paper feeding in chain-type printing equipment within ±5mm.
It is normal to control the accuracy of the paper feed of the automatic paper feed within ±1mm.
It should be specially noted here that the accuracy of the paper-feeding position of the curved cardboard has a great relationship with the speed of the machine, and there is a big difference between the upper and lower curved cardboard. Where is the reason?
The automatic paper feeding model handles the bending of the cardboard (three-layer single-pitch cardboard is easy to appear), and it is largely necessary to rely on the wind to absorb the cardboard, forming a vacuum to attach the cardboard to the feeding surface, and then pushing The cardboard or leading edge feed roller is fed into the traction roller.
The bent cardboard is easy to handle, and if the bent cardboard is relatively hard, it is difficult to form a vacuum when the suction is not smooth, and the uneven paper feeding position after the air leakage is relatively large.
2. Printing accuracy Chinese Sourcing agent forPrinting machine
If the company produces beautifully-printed high-grade corrugated boxes, it should purchase high-precision printing equipment. The overprinting error of the equipment is controlled within ±0.5mm or higher.
However, most of the product requirements on the market are not too high, so the overprinting error of the printing equipment can be controlled within ±1mm to meet the printing requirements of ordinary corrugated boxes.
This standard is actually very loose, and qualified printer manufacturers should be able to do it.
3. Slotted die cutting accuracy
The accuracy of the front, rear, left and right movements of the slotting die-cutting of the equipment is intuitively reflected in whether the carton is easy to form and whether it is square.
This accuracy also affects the smooth completion of the rear nail Box
and the glue box process, especially the fully automatic nail box or glue box.
Whether the carton after molding is beautiful, whether there is a large or small mouth when the cover is up and down, and whether it is skewed or not, is related to this precision.
Accuracy error control within ±1.5mm is acceptable.

These accuracies are not only reflected in the process of constant speed, but also in the process of the highest speed and lowest speed of the machine, and also in the process of shifting.
Testing with these methods can reflect the accuracy and stability of the machine. profisional sourcing agent for Printing machine Sourcing
