In the process of forming corrugated boxes, the technology of gluing boxes has been used since last century. At present, it has been widely used in Europe, America and other developed countries, and it is also widely used in China. The reason why it is widely used is that the gluing process itself has many advantages in favor of the production of cartons
It is beneficial for paper enterprises to recycle old cartons. It can be beating directly without nail removal, which is beneficial to environmental protection;
Low cost. Compared with the nail box process, the cost can be greatly reduced by using adhesive. Especially in recent years, with the continuous emergence of rubber powder and new technology, and the rising price of steel, there is an account between the two;
The carton is not damaged, not damaged corrugated, can relatively improve the strength of the carton, is conducive to the long-distance transportation of packaging products;
It is more conducive to the inner packaging materials not to be scratched by nails, especially the inner soft packaging materials or liquid packaging materials, such as fresh milk boxes, etc;
It can greatly improve the production efficiency, especially the automatic gluing machine, which can save manpower. One gluing machine can replace three nailing machines;
It can be matched with the corresponding printing unit to form a carton production line "one-stop" configuration.
Harbin Fenghua Packaging Co., Ltd. is one of the first designated carton machinery manufacturers of China National Packaging Corporation. As early as the 1980s, it introduced foreign advanced carton gluing machine technology, and combined with the characteristics of China's carton industry to carry out transformation and innovation, and produced many batches of semi-automatic carton gluing machines. However, due to the slow development of China's carton industry in recent years, especially in the northern region, the backward equipment and technology, and the impact of product structure. So stick box machine, especially stick box technology popularization is not very ideal. However, with the popularization of carton gluing technology in recent years, some large and medium-sized carton enterprises also have a significant improvement in the understanding of carton gluing technology. At present, there are mainly automatic and semi-automatic gluing machines in China.
Semi automatic gluing machine
The semi-automatic gluing machine can be divided into two types: the first type is widely used in China. It is mainly used for folding, gluing, shaping, conveying, pressurizing, counting, drying and other functions of cartons. The whole machine is composed of feeding department, gluing department, shaping department, conveying and pressurizing department, receiving and counting department, etc. The operation procedure is that the workers manually fold the processed whole piece of paperboard and send it to the gluing section. The gluing section automatically applies glue on the bonding part of the paperboard and sends it to the shaping section through the roller. After shaping one by one to a certain amount, it will automatically transfer pressure, blow dry and finally complete. This kind of semi-automatic box gluing machine is suitable for the standard outer packing box with one piece of folding and rocking cover, and the carton must be pressed well along the corrugated "folding line", otherwise the glued carton may produce waste products. The machine is very suitable for the paperboard after die cutting. The maximum size of folded paperboard is 1200mm × 1200mm, the minimum size is 400mm × 400mm, and the production speed is 50-70 pieces per minute.
Another kind of semi-automatic box gluing machine is evolved from the structure of box gluing machine. This kind of box gluing machine is composed of automatic feeding part, polishing and gluing part, conveying part and manual folding and pressing part. The workers fold and press it by hand, and then put it into the air pressure department to press it after a certain amount. It is characterized by the feeding section automatic feeding speed is fast, but can not feed folded cardboard, can only feed flat, this kind of sticky box machine feeding section is similar to the front feeding structure. It is fed by special tape and roller. At the same time, it can also complete the bonding of two cartons, and can complete the bonding of special cartons such as special-shaped cartons and partial mouth cartons. Its grinding and gluing part can accurately roughen and glue the parts that need to be glued, and it can also use the nozzle of the machine to spray glue locally on the special-shaped box. There are 12 working positions on both sides of the machine, 12 workers can operate at the same time, and the production speed is also considerable.
Automatic gluing machine
The full-automatic gluing machine is to feed, fold, glue, pressurize, reshape and bind the paperboard automatically. Its characteristics are saving manpower and high efficiency. At present, Europe and the United States and other developed countries basically adopt this production mode, while China only adopts it in a few large-scale carton enterprises, so its market prospect should be good.
Reasonable purchase
The author thinks that the carton enterprises should consider the following aspects when they choose the carton gluing machine
Consider their own comprehensive processing capacity, such as how many million square meters of cartons per year;
The structure of the product. This point is very important, such as less variety, large batch, standard folding into a box, the plant area is also spacious, and there is a high-speed printing slotting unit, you should choose the automatic gluing box unit;
If the small and medium-sized carton enterprises and the product structure is very complex (refers to the variety, both ink printing carton and offset color carton), it is necessary to choose the second kind of semi-automatic gluing machine. Because it can stick two pieces of box and special-shaped box, it can adapt to a wide range;
If you don't produce offset color box at all, you should choose a semi-automatic gluing machine. It can fully meet the needs of production. For example, in Harbin and "Longdan", "Huiyuan", "Wandashan" and other brand products matching carton enterprises are basically using this kind of gluing machine. Its investment is small, generally between 60000 and 80000 yuan, which can greatly save manpower, improve efficiency and benefit. If it can be used with die-cutting machine, it is more likely to improve product quality.
