Description

A laser die-cutting machine capable of precise positioning and plateless cutting of arbitrary graphics

technical field

The invention relates to an in-mold decal film die-cutting machine, in particular to a laser die-cutting machine capable of precise positioning and plateless cutting of arbitrary figures.

Background technique

With the continuous innovation of printing technology, in order to pursue better product quality, an in-mold decal technology has emerged in recent years. In-mold decals and container molding are completed at one time, eliminating the process of manual transfer and secondary processing, without interrupting production. You can add and replace decals, so that the packaging production speed is faster, the product efficiency is higher, and the production efficiency can be increased by 30%. Compared with traditional thermal transfer printing, in-mold decals also have the following advantages:

1. Anti-counterfeiting function. The in-mold decal system is relatively complex, and it is difficult for ordinary printing technology to meet the standard of in-mold decals. Therefore, in-mold decals are used as anti-counterfeiting functions in China, which directly enhances the anti-counterfeiting function of products and is more in line with the brand protection needs of high-standard enterprises. , provides a very reliable brand maintenance method for plastic packaging product users and manufacturers who pursue quality, quality and brand.

2. The in-mold decals are beautifully printed. Because the decals in the film and the plastic products are naturally integrated, they can be deformed with the deformation of the bottle body, and there will be no bubbles, wrinkles, etc., and special effects such as laser and aluminum plating can be done, which greatly improves the packaging grade of the company's products.

3. Hygiene, safety and environmental protection. Ordinary thermal transfer printing needs to wait for the injection molded product to be molded again, and the in-mold decal and the container are completed at one time, which prevents the occurrence of secondary pollution and the environmental pollution caused by pasting. In addition, since the materials used for in-mold decals and injection molded products are the same, they can be recycled together, and the recycling rate is high.

4. The product decals will not fall off, wear and fade. The in-mold decal is processed in the film and integrated with the product. The decal has the properties of waterproof, oil-proof, mildew-proof, acid and alkali resistance, friction resistance, etc., and is not easy to be damaged under special conditions.

5. High efficiency and high benefit. The in-mold decal film die-cutting machine is an important equipment for the post-press processing of printed packaging products. It is not only an efficient, safe and high-quality molding equipment, but also a replacement product of the flat die-cutting and creasing machine. , which is favored by packaging and printing enterprises.

Based on the above advantages, in-mold decal technology has become more and more popular among manufacturers in recent years.

In the process of in-mold decals, in-mold embossing film is inevitably used, and the in-mold embossing film is in a whole roll state before processing.

The slitting is to cut the cut-to-length according to the pattern size by the slitting machine, and then put the cut semi-finished product on the die-cutting machine for die-cutting to obtain the required in-mold decal pattern, and then stack the obtained in-mold decal pattern and put it in the injection molding machine. to be processed.

In the process of the above in-mold flower film processing, two equipments, the slitting machine and the film cutting machine, must be used, not only the purchase cost is high and the floor area is large, but the most important thing is that the sequential separation and processing of the two equipment will involve Two positioning, it will seriously affect the processing efficiency, it is difficult to meet the needs of mass production. In addition, in the above die-cutting process, the die-cutting machine needs to be equipped with a dedicated physical die. The physical die is designed according to the actual needs of the in-die decals. Different in-die decal patterns need to be replaced with different dies, not only the die The purchase cost is high, and the constant replacement of the die will bring great inconvenience to the actual processing, and it will also reduce the production efficiency on a certain basis.
