In recent ten years, there have been more and more color printing cartons. Cartons should not only protect internal products and facilitate transportation, but also display internal products to attract consumers' attention and play the role of advertising.
Cartons produced by die-cutting technology can have gorgeous shapes and elegant curves, which is very suitable for the market demand for color packaging cartons.
This is impossible for the carton produced by slotting technology, and it is precisely because of this market demand that the carton die-cutting technology has developed rapidly.
From semi-automatic die-cutting machine that needs manual feeding one by one (Guangdong is used to calling it asia pacific breweries (reading bie), I don't know if it's dangerous or not, and it's easy to hurt my hand) to full-automatic flat die-cutting machine.
From manual paper feeding chain rotary die cutter to automatic rotary die cutter and automatic paper feeding, printing and slotting integrated printing machine with die cutter.
I have seen three ways to die-cut corrugated boxes:
[If! SupportLists] 1。 [endif] flattening
[If! Support list ]2. [endif] circular flattening
[If! Support list ]3. [endif] circle pressing circle
The advantages and disadvantages of these three methods are briefly introduced below.
1. Flat die cutting
Flat die cutting adopts flat die cutting machine. When die-cutting, the blade cuts through the whole corrugated board at the same time. Die-cutting has the highest precision and is widely used. Adhesives, cardboard, corrugated cardboard and other materials can be used.
There are two types of flat die cutting machines:
[If! SupportLists] 1。 [endif] Vertical semi-automatic die-cutting machine, that is, asia pacific breweries mentioned earlier, now also has automatic feeding and receiving models.
Domestic manufacturers are mainly concentrated in Ruian, Zhejiang.
The vertical die-cutting machine has simple structure, convenient maintenance and easy operation, and it is relatively simple to replace the die-cutting indentation plate.
However, the user's labor intensity is high, and the production efficiency is low. The working times per minute are mostly 20 ~ 30 times, which are mostly used for small batch production and processing.
[If! Support list ]2. [endif] Horizontal lithographic die cutting machine
There are semi-automatic and fully automatic models.
The overall structure of the horizontal flat molding machine is similar to that of a sheet-fed offset press. The whole machine is composed of paperboard automatic input system, molding part, paperboard output part, electrical control, mechanical transmission and other parts, and some parts also have automatic waste removal devices.
The advantages are obvious: safe and reliable work, high degree of automation and high production efficiency.
The disadvantage is that the procurement cost is a bit high, which is not suitable for large-scale die-cutting operations.
2. Circular flattening die cutting
Cylindrical pressure roller is used to replace the pressure plate, generally, the pressure cutting roller is above and the die cutting plate is below, and the die cutting is carried out in a "line contact" way.
When molding, the pressure on the machine is relatively small, and the force distribution is relatively uniform, so that the load of the machine is relatively stable, and large-format die cutting can be carried out. This method is suitable for die cutting of products with different materials and thicknesses.
Circular flattening die-cutting is a working cycle of stopping or turning once or twice, so it is inefficient and rarely used at present, and it can still be seen in some small carton factories.
However, the purchase cost is relatively low and the security is not bad.
Three. Rotary die cutting
Rotary die-cutting machine has been in China for more than 20 years, and its forming drum can rotate continuously at high speed, so its production efficiency is the highest among all kinds of die-cutting and creasing machines.
The precision of die-cutting carton is high, which can be controlled within 65438 0 mm. At the same time, it has the advantages of simple operation, safety and reliability and long service life.
What plane are you using now? Or are several models being used in combination?
I am Liu Hairong, and I have been working in the corrugated box packaging industry for many years. I'm not sure what I can do, but I can learn from some experience.
