　　Types and performance of domestic paper machines

　　Side push gauge paper machine. For example, Weifang Huaguang D81A, Wenzhou Weiyan YP1A3 and other machines. In this type of machine, the water roller and ink roller are separated, but there is 1 imprinting water roller and 2 imprinting ink rollers. The paper is fed by a suction nozzle for printing, and the paper is fed straight. The paper is fed with a bridge. The paper is conveyed to the The front gauge is pushed to the side to set the position. The overprint accuracy is relatively poor. In addition, the ink uniformity of the two imprinting rollers on the layout is poor. It is difficult to print color prints, especially color solid prints. Therefore, Such machines should also be included in the category of light printing equipment, priced at around 60,000 yuan.

　　Rear-nozzle type horizontal paper feeding side pull gauge paper machine. For example, Nanning color ball J801-I, Beijing Duoyuan PZ1440 and other machines. This type of machine uses a large paper machine-style rear suction nozzle to feed the paper. The paper is fed horizontally without a bridge. The paper is sent to the front gauge by the paper transfer wheel, and then the paper is positioned on the front gauge by the friction of the ball on the roller. Then, the paper is positioned by pulling the paper side by side. The front rules of this type of machine can be adjusted, which is very conducive to multi-color overprinting. It separates ink and water, 3

　　Paper machine printing was originally collectively referred to as "light printing". It means that the machine is light in weight, simple in structure, and light in pressure. The printed products can only be used as office supplies. In fact, it is not. With the continuous development and improvement of large eight-opening and six-opening machines, new technologies such as water and ink separation, double-sided drawing gauges, paper crossing bridges, and frequency conversion speed regulation are adopted. These machines print short-run magazines, samples, albums, and color Promotional materials, non-dry papermaking and other products are still competent, so they are more and more favored by small and medium printing companies.

　　At present, the paper machine used by small and medium printing plants in my country. There are both domestic and imported ones. The price of imported machines is 1 to 2 times higher than that of domestic machines. Due to capital constraints, small and medium printing companies have a large demand for domestic paper machines, and some varieties are even in short supply. It is the paper machine manufacturer’s Golden age.

　　my country has more than 20 paper machine manufacturers of various sizes, distributed in various provinces, such as Beiren, Yingkou Guanhua, and Shandong Weihaibintian. Shandong has the largest number of paper machine manufacturers. In addition to Weihaibintian, there are Weihai Printing Machinery, Weifang Huaguang, Weifang Eastern Airlines, Weifang Sanjia, and Yantai Wuzhou. Judging from the paper machines manufactured by various factories, it can be roughly divided into the following types.

　　1. Desktop eight-open paper machine. For example, Yingkou J81, Chongqing Sanke J818, etc., weighing about 70kg, use friction rollers to feed paper. Most of the machines use zinc oxide paper-based plates, and most of the products are materials, supplementary textbooks, examination papers, etc. This kind of machine is small in size and light in weight. It is a light printing equipment and costs about 16,000 yuan.

　　2. Ink and wash hybrid paper machine. For example, Yingkou 1800AWD, Weihai printing machine Y1A3 and other machines, floor type without bridge, water roller and ink roller mixed together, straight feed paper, adopt suction nozzle to feed paper, no rules, weight about 600kg, most suitable for oxidation Zinc plate printing is a short version of text. Usually the printed paper weight is 60～100g/m2, and it is difficult to print paper under 40g/m2. Therefore, this type of machine can also be called a light printing equipment, and the price is 60,000 yuan. about.
