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.

1. The carton sticking edge and the rubber wheel width should match. In the process of automatic paste box, the width of the adhesive mouth of the carton should meet the requirements of the folder gluer. If the width is too narrow, the quality of the paste box will be affected. If it is too narrow, it will overflow. If it is too wide, the pre-folding will be affected. In addition, the concentricity of the rubberizing wheel should ensure accurate packaging and anti-counterfeiting, and the knurling of the edge should be free of wear to ensure uniform sizing.
2. Before applying the glue, make sure that the conveying path of the carton edge is parallel to the conveyor belt.
3. The gap between the upper and lower rubber wheels and the amount of glue applied should be suitable for food packaging to ensure that the glue layer is thin and uniform.
4. The folding part is equipped with a folding transmission. If necessary, the folding transmission should be adjusted to ensure accurate positioning of the adhesive.
5, the adhesive that has been coated with adhesive must not touch other parts of the machine, otherwise the glue will accumulate in this part, and finally reach the part where it should not be glued.
6, the location of the glue should be appropriate, too far from the crease line, the box is not beautiful, too close may make the position of the glue not coated with glue binding, resulting in a difficult box.

1. The paper feeding method of the sponge belt is adopted, and the elastic adjustable paper knife is combined with the vibration motor to smoothly and accurately separate the paper embryo. The clutch under the photoelectric control controls the paper feeding transmission system to ensure that the paper embryo accurately enters the glue-on part, so that the paper is not stopped.
2. The imported hot melt adhesive system under photoelectric control can be adjusted according to the size of the paper embryo and the position of the glue, to meet the production requirements.
3. The working part of the forming department adopts the organic combination of the adjustable inner mold and the outer mold controlled by photoelectricity and cylinder to accurately and consistently complete the paper embryo forming. The inner and outer molds can also be adjusted according to the size of the paper embryo to meet the processing requirements of different sizes of paper boxes.
4. The conveying department is driven by a separate speed regulating motor, which can be adjusted according to the production speed of the main machine to ensure the orderly output of the finished carton.
5. The inverter is used to control the motor drive, the speed regulation is balanced, and the power is saved.
6. Adopt advanced timing belt and timing wheel drive to ensure accurate, stable and low noise transmission.
