Today, ROYAL, a professional folder gluer manufacturer, will introduce some basic knowledge of folder gluers. The article will introduce in detail the working principle, classification, maintenance, technology, application, and characteristics of folder gluers in six aspects to help you more comprehensively and meticulously Get to know the folder gluer.
In the packaging and printing industry, the application of the folder-gluer is the last process of packaging box processing. It is to fold the printed and die-cut cardboard into a shape and glue it. The machine-glued box replaces the manual box-gluing method, reducing Labor costs and improving efficiency.
Folder gluer parts are divided into the paper feeding part, pre-folding part, hook bottom part, forming part, and box pressing part. According to the function, the folder gluer can be divided into smooth sticky box gluer, hook bottom box gluer, etc. The general box gluer does not have the groove bottom function or even does not have pre-folding, and the better ones have pre-folding. Both are pre-folded. Of course, a groove-bottom box-gluer must be used to make hook-bottom boxes. A box-gluer with better functions can also make hexagonal and heterosexual boxes, but it needs to be equipped with a glue spraying system and other devices.
1 Working principle of folder gluer
The working principle of the automatic folder gluer is that after the power is turned on, the entire conveyor belt starts to move, and the die-cut semi-finished carton is placed in the paper-feeding position. To the middle belt (such as semi-finished cartons with a surface treatment such as coating or polishing), after entering the middle, the corresponding cartons can be glued on the inner edge by the glue gun at the same time) the conveyor belt transports the cartons to the back glued part for pressure packaging.

3 Maintenance of folder gluer
1 The machine should be kept clean and cleaned frequently.
2 Wipe the mechanical belt with clean water to keep it clean and prevent slipping, especially to prevent sticking to the belt. The rubber wheel and the plastic box at the bottom of the hook must be cleaned after getting off work every day, otherwise, the glue in the plastic box will freeze and affect the gluing effect.
3. The plastic box of this folding part should be kept clean and cleaned frequently.
4 It is strictly forbidden to adjust the speed when the governor is stopped, otherwise the belt will be seriously worn.
5 The brackets, shafts, and rods of the inner row boards should be cleaned frequently. It is best to use a mixture of lubricating oil and butter and shake it from side to side to prevent rust.
6. It is best to drive slowly before starting the machine and check whether the machine is abnormal.
4 Folder-gluer technology development
At present, the proportion of hand-glued boxes in the domestic market is still quite large, accounting for half of the box-glued market. However, as there are more and more special-shaped boxes on the market, and it is still growing, this demand has greatly promoted the application of automatic folder-gluers and improved the production efficiency of enterprises. In 2007, the output value of my country's packaging and decoration printing industry reached 140 billion yuan, accounting for 31.82% of the total output value of the printing industry that year. With the rapid development of the national economy, the packaging industry has maintained a good momentum of development. Folder-gluer is the last process of packaging box processing, and it is a device that folds and glues printed and die-cut cardboard together. Domestic development The domestic automatic folder-gluer manufacturing industry started relatively late, and only began to develop in the 1980s and 1990s. At present, the product quality is still relatively low, roughly equivalent to the level of foreign advanced enterprises in the 1960s. Most automatic folder-gluer manufacturers are imitating foreign equipment. Of course, there are also some domestic manufacturers who introduce advanced foreign technology at any cost and conduct independent research and development. Card.
5 application analysis of folder gluer
In the packaging and printing industry, the folder gluer is one of the important post-press processing equipment. At present, with the rapid development of my country's packaging and printing industry, the application of box-loading machines is becoming more and more extensive. Packaging boxes for food, medicine, health care products, cosmetics, wine, light industrial products, etc., are basically processed by box-sticking machines. However, for a long time, the industry has paid far less attention to folder-gluers than pre-press and printing equipment, and the understanding of folder-gluers is far from enough. Many packaging and printing companies still have some misunderstandings when purchasing folder gluers. How to correctly treat the gap between domestic laminating machines and imported laminating machines? How do domestic folder-gluer manufacturers respond to the challenge? How does a packaging and printing factory choose a fully automatic folder gluer? What is the future development prospect and direction of folder gluer? This article will discuss these topics with you.
Comparison of domestic and imported
Domestic folder-gluers have an advantage in price, generally around 30,000 to 100,000 yuan, while the price of imported folder-gluers far exceeds this figure. For example, the price of the BOBST MEDIA series automatic box loading machine is more than 1.2 million yuan. However, there is still a big gap between domestic gluing machines and imported gluing machines in terms of quality and performance, and it is difficult to compete with imported gluing machines, which is mainly reflected in the following aspects.
(1) In terms of box type adaptability
The function of the domestic box glue machine is relatively simple, and it is generally only suitable for one or two general box types. At present, it can only produce ordinary box-shaped square boxes. However, foreign box glue machine manufacturers pay special attention to customers' processing requirements for complex box shapes. Therefore, the imported box glue machine can adapt to more diverse box types, such as hexagonal boxes, octagonal boxes, and special-shaped boxes.
(2) In terms of scalability and flexibility
The imported box-sticking machine is more scalable and adopts a modular design so that users can stick boxes according to the specific conditions of the product. Install the corresponding functional modules or components on the machine, without having to modify the machine model structure, with high flexibility. In contrast, domestic luggage glue manufacturers are much inferior. For example, some box gluers can only be used as ordinary linear boxes or bottom boxes with locks. Adding additional functionality is more difficult and the structure of the model must be modified.
(3) In terms of stability
In terms of stability, imported folder gluers also win. The failure rate of domestic folder gluers is relatively high. Therefore, many people choose domestic equipment for packaging. Printing plants generally have multiple self-made folder-gluers, so as not to affect normal production and delay delivery due to machine maintenance.
(4) In terms of gluing speed
The normal production speed of the gluing machine can reach 450m/min or 500m/min, and the maximum can reach 650m/min
(5) In terms of the degree of automation
In terms of automation, domestic folder-gluers cannot be compared with imported folder-gluers. For example, after a product is produced, another different box is replaced. In the case of high-end products, the adjustment of domestic laminating machines is more troublesome, and it is basically done manually, which is time-consuming and labor-intensive. The imported laminating machine adopts automatic control and can display specific values on the display screen.
For the degree of automation of folder gluers, foreign labor costs are relatively high. Therefore, foreign users have more prominent requirements for the degree of automation of the folder gluer. The high degree of automation of the equipment means that the number of employees can be reduced. cut the expenses. This is not the case in China, where labor costs are relatively cheap, which is a feature of the domestic market. Therefore, domestic users do not pay much attention to the automation of folder-gluers, which is also one of the factors restricting the development of domestic folder-gluers.
(6) In terms of operability
In terms of operability, imported folder-gluers are simpler and more humane than domestic folder-gluers, while domestic folder-gluers are humane. Aspects are worse and look more "stiff". Many folder gluer manufacturers and users think that as long as the machine can run normally, everything will be fine. As for human nature, they give little thought. Some folder-gluer manufacturers don't even think it's worth the effort.
(7) In terms of service life
The service life of domestic folder-gluers is not as good as that of imported folder-gluers, mainly because the materials and processing technology used by domestic folder-gluers lag behind foreign countries. caused.
Although there is still a considerable gap between domestic gluing machines and imported gluing machines, domestic gluing machine carton machines are more adaptable to paper. The quality of paper used abroad is relatively good, while the quality of domestic paper is relatively poor. Therefore, the paper of the domestic automatic folder-gluer has a wider range of adaptations.
6 Development Trend of Folder Gluer
1. Versatility and mobility
From the perspective of international market share, linear boxes account for about 60%, lock-back boxes account for about 30%, hexagonal boxes, octagonal boxes, special-shaped boxes, etc. account for about 10%, and the proportion of linear boxes is declining, and the proportion of special-shaped boxes is gradually increasing. Increase. At present, standard linear packaging boxes are still widely used in my country's packaging market. With the acceleration of economic globalization and the intensification of market competition, consumers and packaging users have higher and higher requirements for packaging boxes. In order to increase the added value of products, the box-shaped designs of packaging boxes are becoming more and more diverse. The demand for some advanced automatic bottom-locking color boxes is also increasing, including toy boxes, wine boxes, medicine boxes, etc. This kind of complex box type cannot be produced effectively by manual or simple box glue machines. In terms of box type adaptability, domestic fully automatic folder gluers are far inferior to imported ones, especially in the production of special-shaped boxes. At present, domestic fully automatic folder-gluers are still not up to the requirements, and domestic manufacturers need to redouble their efforts.
2. High speed and high output
As a color box supplier, whether it can provide instant production and delivery has become the prerequisite for customers to choose from. On-time delivery, a sufficient quantity of cartons in the shortest time will help to get the order. The folder-gluer is required to be easy to adjust and fast in production. Of course, stability is also essential, as manufacturers need to be ready for production at all times.
3. Adapt to the production of small-batch packaging boxes
Currently, there are more and more small-batch jobs. my country's small batches of plastic boxes mainly rely on manual work. If the automatic folder-gluer can be used in the future, if a breakthrough is made in small batch production, it will be more conducive to the promotion and application of the automatic folder-gluer.
4. Increase the degree of automation
The printing industry as a whole is moving towards tighter deadlines, shorter operating cycles, more job changeovers, and the need to reduce set makeready times. face increasing pressure. The higher the degree of automation of the automatic folder-gluer, the lower the dependence on the operator, and at the same time, it can improve production efficiency and reduce the labor intensity of the operator. In terms of operability, it will become more and more humanized, reflecting the "people-oriented" design concept.
