In addition to the need to print beautiful pictures, the production of cartons requires processing such as crepe paper, die-cutting, forming and kneading paper.
The quality of each process is directly affected by the quality of the final product. Therefore, every process is very important. At present, many cartons in China are processed by a folder-gluer, but there are still many small-scale processing plants. produce.
        First, the process points of the folder gluer
1. Check the production order and check the quality of the cardboard paper. The standard moisture content of the cardboard paper is 12%.
2, the preparation of adhesive, the quality ratio of each component is: white latex: water = 3:1.
3. Put the white paper inside the glue, stack the cardboard paper on the platen in front of the glue machine, and push the paper to the operators on both sides according to the speed of the glue machine. The operator will take it first. The cardboard paper is then coated with the glued paper and aligned with the two rule sides of the cardboard. When the paper is taken, the two people should cooperate with each other. A slight negligence may cause the paper to rupture or wrinkle.
4. Flatten, put the cardboard paper of the good paper into the flattening machine, set the pressure to 20MPa and the time is 5 minutes.
5, the end of production, self-test quality, count the number and hang the production identification plate, and transfer the production process.
6. Inspection items include: the cleanliness of the paper, such as glue, adhesion and cleaning.
        Second, the precautions of the folder gluer
1. Pay attention to the influence of the ratio of the adhesive on the flatness of the paper surface, and master the uniformity when applying the glue.
2, the paper must be flat, in place, pay attention to the paper can not exceed the rules of the cardboard paper.
3. The formulated adhesive should not be too thin to prevent wrinkling of the inner paper.
4. Wash your hands frequently to ensure that the paper is clean and clean.

         As one of the indispensable equipments in the packaging industry, the folder gluer is of great importance. It effectively makes the product more standardized, but in the process of use, we can not ignore an important issue. That is the traditional manual paste-to-box process, the scrap rate is very low, which is mainly due to factor control. At present, with the development of society, most enterprises use the glue-gluer equipment, which has been able to control the tension of employment, and can make production more efficient. Although the advantages of using a folder-gluing machine are numerous, the scrap rate has always been a headache for users. How should the user reduce the reject rate of the paste box when using the folder-gluer device?
         1. In order to control the reject rate of the folder gluer equipment, we know that the process and structure of each package are different, so the reasonable use of the adhesive can effectively reduce the rejection rate of the product.
         2. Control the inlet direction of the material. For example, in order to complete the cartoning process of the carton better and faster, the fiber direction of the carton or the corrugated direction of the corrugated carton should be as perpendicular as possible to the carton direction of the folder gluer. .
        3, the details of the paste box processing, including: paste box position detail design; paper edge is best designed as a straight line; large products are best designed using die-cut oblique position method; in the production process to avoid friction between the product and internal components.

         As the requirements for carton packaging materials continue to increase, the market not only requires aesthetics for the packaging carton, but also puts forward more functional and quality requirements. Due to the demand for modern high-grade products, it is no longer the original simple paper, but many new plastic materials such as coated paper, glazing paper, coated paper, aluminized paper, PP, PET, etc. The gluing process has brought new challenges.
         For ordinary paper, water-based cold glue can be well bonded, and new materials such as coated paper, glazing paper, and aluminum-plated paper may not adhere well or may not be bonded. Many domestic enterprises adopt partial coating, partial glazing, surface grinding or cutting paste line, using special special glue, etc., although these methods solve some process problems to some extent, but the process, efficiency and quality The guarantee is intangible and costs are incurred.
         In order to solve the above problems, a plasma surface treatment machine is used to perform certain physical and chemical modification on the surface film, UV coating or plastic sheet of the packaging box to improve the surface adhesion, so that it can be easily bonded as ordinary paper. The use of conventional water-based cold glue enables the film or glazing board to be reliably bonded on the folder-gluer, eliminating the need for partial filming, partial glazing, surface grinding and tangential processes, etc. Replace different special glues, etc. with different cardboard.
         After plasma surface treatment, it can not only enhance its applicability to glue, but also achieve high-quality bonding without relying on special glue. Moreover, the spreading property of the surface is improved, and the generation of bubbles or the like is prevented. The most important thing is that after atmospheric pressure plasma treatment, carton manufacturers can get high-quality products with better quality at lower cost and higher efficiency.

         In the process of printing, the folder-gluer machine will inevitably have no problem. Only in daily life, the maintenance work should be done as much as possible to improve the performance of the equipment. If problems occur, you should first find the cause and then find the corresponding solution.
         1. The adhesive is not firm, you can check the amount of glue applied. If it is a carton of UV varnish, you need to install the grinding device on the equipment, and the bonding parts can be glued to be properly bonded. Special UV oil adhesive, users can consider it).
         2, the surface of the printed product is scratched, which is related to whether the origami is using iron wire, especially the small box is often difficult to use the belt crease, the wire is easy to scratch the surface, for a small carton, such as the daily use of the comb The small box can be used to bring creases with leather.
         3, the paper is not in the right direction, which needs to adjust the position of the paper stopper and the pressure balance of each part, which can be handled by the experience of the captain of the paste box.
         4, easy to form the bell mouth, this is a comprehensive problem, it is necessary to pay attention from the die cutting stage, but if the equipment can be specially designed in the angle of the paper folding part, such as the knife origami, the problem is easy to solve And, we have lengthened the length from the paper feeding section to the folding section during the design. Making the paper feeding a gradual process makes the box shape more regular.
         The above four situations are relatively common problems. The application of the paste box machine requires mastering skills to avoid equipment failure and ensure printing results.

        There are three main reasons for the sticking of the carton of the glue box:
1. The groove of the indentation line is too wide and the pressure of the indentation is not enough, so that the pressed line is not full, and it cannot be accurately folded according to the indentation line when folded.
2. The folding transmission is improperly adjusted, and the conveying speeds of the left and right sides of the box are inconsistent, causing the sticking of the stick.
3. The groove width of the indentation line increases the indentation pressure; adjusts the folding transmission to make the conveying speed of the left and right sides of the carton consistent; reinstall the folding rod.
         Misalignment of the adhesive mouth means that the adhesive mouth is misaligned, and the misaligned paper box cannot be formed well. This phenomenon is usually caused by the accuracy of the adjustment of the machine, mainly because the operator's understanding of the box type and folder-gluer machine has not affected its operation level. Therefore, strengthening the training of operators, improving their operational skills and their understanding of complex box types can effectively avoid the problem of misalignment of the adhesive mouth.
         How to deal with the glue sticking machine: The overflow glue means that the excess adhesive flows out of the adhesive mouth. This phenomenon is mainly caused by misalignment of the adhesive mouth and excessive use of the adhesive. By grinding the adhesive mouth and reducing the amount of glue, the occurrence of glue overflow can be effectively reduced.
