水墨印刷机种类之横印链条式印刷开槽机
横印式的链条印刷开槽机,这种印刷机也是采用人工放纸,运用链条上固定的推纸板进入印刷组的印刷方式。
Cross printing chain printing slotting machine, this type of printing machine is also used artificial paper, the use of a chain of fixed push cardboard into the printing group.
与前面讲的直印机不同处在于,加入了开槽部分可使印刷开槽一次成型,还有的也装了圆压圆模切组。
Speaking in front of the printing machine is straight different, joined the slotting part can make printing a molding, and also with the rotary cutting group.
这种印刷机在广东以外的地区使用最为普遍,近几年迫于人工成本的压力,广东使用的也多了起来。为什么呢?
This type of printing machine is most commonly used in areas outside Guangdong, and in recent years the pressure of labor costs is forced by Guangdong. Why?
因为将印刷,开槽分开作业的工序合并后最少减少了一个人,工艺时间也节省了不少,利润也就相应的增加了。
Because the process of printing, slot separation operation combined with a minimum reduction of a person, the process time has also saved a lot, and the profits will be increased accordingly.
这种机型使用的印刷版橡胶的比较多,也可将贴有双面胶的印版放在纸板上需要的印刷位,滚入机组内直接贴在印版辊上进行印刷,但仅限于第一色。
This type of machine has many printed plates, and the printing plates with double-sided adhesive can be placed on the required printing positions on the cardboard, rolled into the machine, directly pasted on the plate roller for printing, but only for the first color.
如果是多色印刷的话,第二色以后的色组就需要分开机器贴板,然后再合机对印刷位,比较麻烦,调机的时间也长。对操作者的技能要求还是挺高的。
If it is multicolor printing, after second colors, the color group needs to separate the machine to stick the board, then the machine will be more troublesome to print bit, and the time of machine adjustment is also long. The skill requirements for the operator are still high.
纸板是横向进纸,大都比较长,链条上固定的推纸板一般都有三到四个,如果推纸板不在一条直线上,采用的又是人工放纸的方式,所以缺点也是比较明显的:纸板进纸很容易歪斜。
Cardboard is transverse paper feed. Most of them are relatively long. There are three to four push cardboards on the chain. If pushing cardboard is not in a straight line, it is also a manual way to put paper. So the drawback is also obvious: cardboard feed is easy to skew.
歪斜进纸的后果是什么呢?
What are the consequences of skewed paper?
印品内容位置的容易移动(印刷整体跑位)就不说了,更关键是斜的,到了开槽组就糟糕了,左右开槽口深度不一样,直接导致纸箱成型不好,箱高是歪斜的。
Easy to move the printing position of (printed overall Paowei) did not say, but the key is inclined, to slot group bad, around the notch depth is not the same as the direct cause carton forming is not good, is a high skew box.
异形纸箱所使用的模切组要求多半是高的,这样更增加了纸板的损耗。所以这种机型带有模切组的是很少见的。
The die cutting unit used in the special carton is mostly high, which increases the loss of cardboard. So this type of model with a die cutting group is very rare.
同时也增加了后工序钉箱(粘箱)的工作量,严重的话会无法达到要求而报废,只能当废纸卖了。
At the same time, it has also increased the workload of the post process nail box (sticky box), and the serious words will not be able to meet the requirements and scrap, only when the waste paper is sold.
开机的速度也必须是均速的,套色印刷的精度在正负1MM之内是比较正常的。
The speed of the opening must also be all speed, and the precision of the color printing is more normal in the positive and negative 1MM.
机器的设计速度大都在80张/分钟左右,人工送料的结构,速度再快也没有用,人是跟不了机器的速度的。
The design speed of the machine is mostly about 80 minutes / minutes, the structure of artificial feeding, the speed is no use, people can not keep up with the speed of the machine.
那么是不是就没有办法了呢?
So is there no way out?
简易的皮带吸风式自动送纸器应运而生,此机型利用伺服控制系统能够与印刷机同步,送纸可以从人工单张送纸变为连续送纸.
A simple belt air suction automatic paper feeder comes into being. This type of machine can synchronize with the printing machine by servo control system, and the paper delivery can be changed from artificial sheet fed paper to continuous paper feed.
保证纸板走正,不但提高工作效率,而且大副降低工人劳动强度,又降低废品率。
To ensure that the cardboard is straight, not only improve work efficiency, but also reduce the labor intensity of the workers, and reduce the rate of waste.
缺点是比较弯翘的单坑(楞)纸板及E坑(楞)无法顺畅的送出,不适合加在直车机型上。
The shortcoming is that the single crater (corrugated) board and E pit (corrugated) can not be sent out smoothly and are not suitable for the type of straight car.
