The glazing process classification method of the glazing machine: according to the glazing coating, it can be divided into oxidative polymerization type coating glazing, solvent volatilization type coating glazing, photocuring type coating glazing and heat curing type coating glazing; Whole surface light, partial glazing, extinction and artistic glazing;
The equipment used for glazing can be divided into: glazing on a separate glazing machine, glazing with a printing unit and a printing machine; according to the glazing coating method, it can be divided into: smear coating, printing and coating. Light and special glazing machine are coated with glazing; according to the input mode of printing, it can be divided into manual paper feeding and automatic paper feeding.

For printing and carton enterprises, choosing a glazing machine with excellent structure, stable performance, convenient operation, high production efficiency, wide applicability and good energy saving is of great significance for scientific and rational organization of production. The glazing machine is an important equipment for surface finishing processing of packaging products such as carton boxes. It plays an important role in improving the surface properties of printed products and improving the wear resistance, stain resistance and water resistance of printed products. Therefore, correctly understanding and understanding the structure and characteristics of glazing equipment, mastering the procurement control essentials of glazing machines is an important part of improving production efficiency and product quality.

Using a glazing machine, after some products are calendered, the surface is prone to cracking (thick paper is more obvious).
1. The temperature in the calendering is too high, so that the water content of the printed matter is reduced, and the paper fiber becomes brittle;
2. The pressure in the calendering is large, which makes the printability and flexibility of the print deteriorate.
3. The selection of post-processing conditions is not suitable;
4. Poor suitability after glazing coating.
The solutions for the above are:
1. Reduce the calender drying temperature and take effective measures to change the water content of the printed matter;
2. Reduce the calendering pressure;
3. Adjust the post-processing conditions to match the suitability of the printed matter (after calendering).
After the calender is calendered, the blank part of the printed matter is light-colored, and the cause of discoloration of the light-colored part is:
1. The ink is poorly dried, and the ink layer has poor solvent resistance;
2. The coating solvent has a certain dissolution effect on the ink layer;
3. The coating layer is not completely dried and the solvent residue is high.
The solution is as follows:
1. The printed matter is dried and then glazed;
2. Reduce the amount of solvent in the glazing coating (solvent that dissolves the ink), allowing the solvent to be changed or changing the coating;
3. Increase the drying temperature and reduce the residual solvent content inside the coating.

A glazing machine is a device that coats the surface of a printed product with a colorless, transparent coating that protects itself and increases the gloss of the print. The glazing process classification method of the glazing machine: according to the glazing coating, it can be divided into oxidative polymerization type coating glazing, solvent volatilization type coating glazing, photocuring type coating glazing and heat curing type coating glazing. According to the product, it can be divided into the whole surface light, partial glazing, extinction and artistic glazing.
1. The glazing head and the conveyor belt are independently controlled by a stepless speed regulating motor.
2. The main body of the drying tunnel is cooled by infrared drying and fan, which is 60% more energy efficient than traditional red line drying.
3. The main body of the drying tunnel is 2 meters longer than the market-oriented products, which improves the glazing speed of the whole machine.
4, electronic thermostat
5, special glazing rubber roller, durable and stable, suitable for a variety of varnish, calendering oil, plastic oil, vacuum oil and other oils, glazing effect is even.
6. The coating glazing adopts the straight-through form, which is easy to operate, fast and efficient.
7, the base, the wall panels are constructed of cast iron, never deformed. Fortune does not affect its structure and accuracy during use and repair of replacement parts.

           The printing glazing machine is divided into a glazing machine and a printing glazing machine. Domestic glazing machines are generally operated in a single machine, the processing speed is slow, and the quality is not high. For this reason, it is often necessary to perform calendering. The large-scale offset printing manufacturers in foreign countries mostly use the printing optical link machine to improve the speed and quality of the glazing. The printing optical ensemble is the development trend of glazing machinery.
           The basic form of the optical linker printing on the printing optical link is to use the dampening device of the last printing unit of the sheetfed offset printing machine to modify the original ink supply system, and then to print the paint; or the last printing unit in the offset printing machine. A coating roller device is attached to the blanket cylinder to apply the glazing paint to the rubber and then to the printing product.
