3. Post-print finishing technology and equipment update speed up The rapid development of surface finishing technology after printing, past surface wax coating has long been surface, the surface coating film has been partially replaced by surface coating (glazing solution). In the past, general drying of the coating was heated by a far-infrared heater (or ordinary heater), and there were disadvantages such as slow down of the product and easy deformation of the product. Recently, UV-curing coatings and inks have been rapidly promoted, and there is a tendency to gradually replace coated films and infrared heat-curing coatings.
At present, the variety and specification of surface decoration machinery and equipment after packaging and printing in China have been diversified, and the number has reached more than 100 species. In the past, some major models and models were imported. After years of digestion and absorption, most models have been able to design and produce on their own. With the application and promotion of high technology, some old-fashioned equipment and processes have gradually been eliminated. For example, surface waxing equipment and processes are gradually replaced by coating or glazing processes, so the curtain-type wax coating machine is basically in In stagnation, few manufacturers reproduce.
With the diversification of printed products, especially the use of small and exquisite handicrafts for various small and exquisite gifts, a large number of small printing equipment and accessories have a broad market and form a new category of applications. Such as multi-functional plastic (glue glue) machine has become a hot commodity in the current market. This gluing machine features include: speed adjustment, humidity and pressure control, liquid crystal display, pre-school function, bottom equipment, general plastic and cold laminating glue adjustment. Some gluing machines can also implement color hot stamping and mounting. They can achieve ideal results in posters, inkjet print documents, leaflets or large maps. In addition, there are other origami binding, bar code label printers, etc. that have also entered the market in batches and become printing post-processing equipment.
Third, the problem analysis Technical and Performance Issues China has a considerable gap in terms of the technology and equipment for finishing and printing on the surface of packaging and printing, compared with developed countries in the world, especially in the degree of automation, feasibility and adaptability of related technologies and equipment. . Judging from the application of technology and equipment, we are still at the initial stage. As for the technical problems of the film coating equipment, domestic equipment and adhesives still have some problems to varying degrees, such as deformation problems, durability problems, separation of the film from the base paper, etc., and there are still no ideal solutions. There are also glazing and glue spraying technologies and equipment for packaging and printing surfaces, which have become the mainstream of packaging surface finishing technology and equipment abroad, and our mainstream is still the surface coating, all of which we have yet to solve.
2. Device model size problem Because many modern products rely on features and personality to win in competition, and a product's best-selling cycle is getting shorter and shorter, the replacement is getting faster and faster, and enterprises engaged in packaging surface finishing want to reach a large scale possibility. Not too big, more depends on SMEs to complete. Therefore, while the equipment is improving reliability, equipment models tend to be smaller and smaller to accommodate changes in the market.
3. Energy-saving issues Printing equipment includes post-press processing equipment. The main energy consumption is its transmission and heating system, while the heating (drying) system is the one that consumes more energy. Heating and drying are mostly electric heating. In the past, heating of many devices was performed using ordinary electric heating tubes (wires), which resulted in high energy consumption and high costs. Saving energy and reducing costs are the company's goal from beginning to end. Nowadays, some equipment has adopted advanced heating and conduction methods such as chemical thermal fluids, infrared heaters, and UV heaters.
4. Functional and adaptive problems Different materials have different performance and effects. As light, some use plastic substrates, some use paper substrates, and some use synthetic substrates. This does not require its equipment to meet the glazing of these substrates and achieve the desired results. In addition, there are water-based, oily, solvent-based, etc. In addition, a new type of special coating has emerged, so the finishing equipment should be able to meet the finishing requirements of these materials, which also requires a wide range of equipment adaptability. In addition, as far as companies are required to occupy as little equipment and space as possible, as many as possible to complete a variety of finishing operations, in order to reduce processing and storage and transportation costs. As a result, multi-functional coating calenders, laminating machines, calendering machines, and glazing machines have appeared one after another.
5. Reliability issues Reliability is the first consideration in the design of any packaging and printing equipment. The fierce competition in the market requires that the equipment can quickly adjust according to customer's product requirements, replace different components and institutions, and can easily operate and reliably control and operate, so as to improve the accuracy and high efficiency of processing.
Surface finishing technology has been applied to a variety of non-professional areas. Such as all kinds of daily necessities, stationery, decorative items, handicrafts, etc., many of the staff used do not have professional skills and operate less well than professionals. This requires mature technology and reliable equipment. Reliability is an important guarantee for the extension and penetration of packaging and finishing equipment and technology to other industries and fields.
