1, instant coating laminator
The invention comprises three parts: gluing, drying and hot pressing. It is small in size, low in cost and flexible and convenient to operate. It is not only suitable for the bonding of large quantities of printed materials, but also suitable for the bonding of small quantities and scattered printed materials such as automated desktop office systems. It has a bright future.
The invention is suitable for laminating (laminating) color printing, wrapping paper, film, film and the like. , can make its surface bright, colorful and waterproof. The advantage of this machine is that the quality of finished products is reliable, but there is a fatal disadvantage that oily glue will produce harmful gases that affect human health during processing, so this technology has been completely banned in developed countries such as Europe and America.
2. Pre-coating press
This machine covers the film in one step, and the used consumables have been coated with glue. When laminating, the glue is melted by heating, and then the film is bonded to the printed matter by pressing. This kind of laminating equipment has the advantages of low price, simple operation and no harmful gas during operation, which is a trend of laminating development and is widely used in small batch printing and digital fast printing industries.
In today's society where more and more attention is paid to environmental protection, it is believed that this technology will one day replace the existing pre-coated film and become the main film covering technology in the domestic printing industry. Its disadvantage is that this technology is not very mature in China, and there are still some problems to be solved, such as single-sided film covering and curling, and it is difficult to cover printed matter with silicone oil.
3. Cold installation machine
Cold laminating machine refers to a thin film laminating machine that runs at room temperature without heating. It directly sticks the adhesive film to the printed matter by pressure. The machine is cheap and widely used, such as plate industry (aluminum plate, iron plate, rubber plate, wood plate, steel plate, glass plate, etc. ), decoration industry, hardware industry and so on.
4. Small film machine
Strictly speaking, this laminator is upgraded from the internal heating plastic packaging machine, but this laminator solves the problem of harmful gas produced by the instant coating laminator. Small-sized laminating machine uses internal heating rubber roller to press the film and feed the film up and down, which increases the heating time of precoated film and makes it heated evenly, so the covered film is smooth and bright, and the effect is the same as that of high-grade laminating machine.
However, the heating power of this laminator is only 500W W W. Although the temperature can be adjusted, the speed is fixed, and only 0.7-0.8 meters can be laminated per minute. Suitable for business card sticking, recipe sticking, photo sticking and graphic printing sticking, especially for some small printing houses, typing and copying shops, business card making institutions and photo studios. In order to reduce equipment investment and cost, more laminators are selected. This kind of laminator has a good market prospect, and it can be said that this kind of laminator has the highest cost performance.
Characteristics of automatic laminating machine
1. The precise design of the paper feeding head enables thick paper and thin paper to be conveyed smoothly. Adopt stepless speed change device and automatic edge control to adapt to different paper feeding methods.
2, accurate exposure, easy to adjust the relative position of exposure in the paper pile during operation, and has a unique continuous paper feeding device, which can feed paper and load paper at the same time to ensure continuous production.
3. The film reel is braked by magnetic powder to maintain a stable tension. The unique pneumatic film pulling device ensures the compactness of the film when pressing and lifting the film, and effectively prevents the film from rolling failure.
4. The invention has the characteristics of high efficiency, wrinkle resistance, easy operation, low cost and high speed. Compared with the traditional laminating machine, it can film the roll materials such as posters and wallpapers.
