Bottle caps are used to seal bottles. According to different functions, there are bottle caps with different shapes and different operation methods. Then there are two-dimensional code applications on the top of the bottle caps. In industrial production, QR codes and DM codes, especially some goods that will involve import and export, will use DM-type QR codes more, which will be more internationally applicable; if they are circulated in the country and have marketing needs, they will use more It's a QR code. The prerequisite for this kind of code is realized by the bottle cap two-dimensional code printing equipment. It is today's high-tech printing and marking equipment, and it is the new darling of product or packaging coding. It plays a role in the national industrial marking machinery and equipment. An important role, and the marking of product packaging is also an important link. Regarding the adhesion of QR code printing, in the market, as a customer or manufacturer, word of mouth reflects that the adhesion of the bottle cap QR code printing equipment is good, and the ink will dry quickly after being exposed to ultraviolet light, adding modification and erasing However, as a bottle cap coding, on the one hand, it is speed, on the other hand, it is the landing problem of installation technology, which will affect the landing implementation of UV inkjet printers. UV inkjet is a new technology. The ink bottle cap two-dimensional code inkjet printer combines the advantages of inkjet printing technology and ultraviolet curing technology. It has the convenience of inkjet technology and the efficiency advantage of adhesion curing. It is known that bottle caps are an important part of beverage packaging, which will directly affect the market demand for bottle caps. With the booming development of the beverage industry, the requirements for product packaging are becoming higher and higher, which drives the demand for bottle cap products. The bottle cap two-dimensional code printing equipment has a high adhesion and high efficiency for the printing effect of the bottle cap. It uses UV environmentally friendly ink, which is not easy to fade, and the printing effect has good gloss, strong adhesion, high DPI resolution, and feels bumps. Hand feel, simple and quick to install in high-speed production line synchronization, the printing content is irradiated by the strong light of LED-UV curing lamp, the content is sprayed and dried, which can meet the needs of a wider range of applications.
