The various depressions on the surface of the white cardboard gift boxes directly make the product scrapped! How to break?

    

1. Some problems occurred in the production of white cardboard gift boxes:

    

The production process of white cardboard gift boxes is a multi-process and multi-step process. Due to the long production process of white cardboard gift boxes, the control of each step is related to the quality of white cardboard gift boxes. However, there will still be some problems in the actual production of white cardboard gift boxes, which will affect the smooth production of white cardboard gift boxes.

   

     

2. Pay attention to the imprinting defects of white cardboard gift boxes together

     

Through 5 issues, the author analyzes the common problems in the process of white cardboard gift boxes - high and low angles, acne, dew, blistering, and embossing. In this issue, let's pay attention to the imprinting defects of white cardboard gift boxes. Imprinting means that after the white cardboard gift boxes are pasted, irregular, irregular and unequal-sized marks appear on the surface of the white cardboard gift boxes, most of which appear as a concave line, shallow pit or radial line. Different depressions are inlaid on the surface of white cardboard gift boxes, which seriously affects the overall effect of the product, especially on the surface of white cardboard gift boxes with dark or all black design. As long as there is embossing on the surface of white cardboard gift boxes, this The parts are reported to be scrapped, causing huge waste to the enterprise. ,    

 

   

3. So, under what circumstances will this problem occur with white cardboard gift boxes? The main reasons are summarized as follows.

    

3.1. Material defect of white cardboard gift boxes

    

Qualified white cardboard gift boxes have a smooth surface, tight fibers, no peeling, damage, delamination, shallow pits, impurities, etc., and the moisture content is between 8% and 12%.

During the random inspection, it was found that the surface flatness of some gray boards was poor, and the tightness did not meet the requirements of the craftsmanship. Slight scratches could scratch the surface, and the shallow ones did not affect, and the deep ones were unavoidable. These gray boards with surface damage Cards, mixed in between are hard to find. In this regard, first of all, we must increase the QC inspection efforts. We must strictly inspect the upper, middle and lower parts of each gray board card of the white cardboard gift boxes. If it is found that the flatness is poor, the surface has swirls, shallow pits, and irregular depressions, it will be rejected. Warehousing; the second is to increase the number of QC random inspections. The more the number of random inspections, the easier it is to find problems, so that the problems can be eliminated in the bud.

   

    

3.2. white cardboard gift boxes cut and scratched

    

During the cutting process of white cardboard gift boxes, the gray board cards should be lifted from the foot board to the paper cutter platform in turn. During the lifting process, try to avoid friction between each stack of gray board cards. Put a piece of waste cardboard at the bottom, and remove the bottom cardboard after cutting. In addition, when the gray board is placed on the foot board, a few pieces of waste cardboard should be placed at the bottom of the foot board to prevent the imprint on the surface of the gray board card due to the uneven foot board. Phenomenon, neat stacking can reduce the indentation caused by the pressure of the upper layer.

   

     

3.3. The die-cutting operation of white cardboard gift boxes is not standardized

    

During the die-cutting process of white cardboard gift boxes, the bottom plate is not clean, and some glue stains or falling paper scraps stick to the steel plate, and the surface of the gray board will be dented when pressing. At the same time, during the operation, when the gray board was taken out, it collided with the completed gray board. Although the scratch marks were not deep, it was enough to affect the flatness of the white cardboard gift boxes after they were pasted. To avoid the above problems, it is necessary to clean the bottom formwork plate, shovel off the glue stains and paper scraps that affect the flatness, and ensure that the bottom plate is flat and clean. At the same time, during the operation, it is necessary to ensure that each gray board is stacked neatly, and the waste edge cannot be allowed to fall off by itself. If the waste edge falls on the top, the previous one can also be pressed out. Pay attention to the operation gesture, as long as it does not fall off.

   

    

3.4. white cardboard gift boxes

    

White cardboard gift boxes The paper support roller of the paper feeding part of the gray board slotting machine, the angle adjustment is unreasonable, and it will also damage the edge of the gray board card. Although it is a slight trace, it is enough to affect the surface quality, which is one of the problems. .

The most important thing is that occasionally there will be sundries on the large roller. When the white cardboard gift boxes gray board is stuck in the conveying of the paper pressing belt and the surface is pressed on the sundries, due to the pressure of the belt, the sundries will be stained. The block can compress the surface of the gray board into a pit, and in such a reciprocating motion, the entire batch of products will be imprinted.

In this regard, we need to clean the surface of the roller frequently, keep it clean and smooth, and clean the surface of the belt regularly to prevent dirt from pressing the surface of the gray board. In addition, in the production process, the air gun should be used to clean the paper feeding part and the surface of the drum regularly, so as to effectively avoid the appearance of indentation.

  

    

3.5. Irregular operation of white cardboard gift boxes

   

After the white cardboard gift boxes are die-cut and slotted, the gray board card must be cleaned. If the process is brutal, it will damage the edge and four corners of the gray board card. The damage to the edge will affect the white cardboard gift boxes regardless of the size. For the quality of the pasting, when cleaning the waste paper, it should be handled gently and stacked neatly. If the waste paper is brought into the middle of the gray board, it will press out the surface of the gray board. Therefore, standardizing the waste removal operation of white cardboard gift boxes can reduce or avoid the appearance of indentation.

   

    

4. Completely eradicate the hidden dangers of white cardboard gift boxes

     

So far, the analysis of the five common defect causes of white cardboard gift boxes is over. The production scenarios of white cardboard gift boxes are ever-changing. Such changes must not only be controlled in real time, but also actively identify problems and find out the reasons. Only by establishing a rigorous work style can the hidden dangers of white cardboard gift boxes be completely eradicated.

   

    

5. The early product design planning of white cardboard gift boxes should avoid hidden quality problems:

    

Especially in the early product design and planning of white cardboard gift boxes, it is necessary to digitize the process of white cardboard gift boxes, so that every step in the production process of white cardboard gift boxes can be accurate; the inspection of materials must be based on standards. Strict implementation of the standard requirements can ensure the stability of the quality of white cardboard gift boxes; the operation in the process is also the key to management, and the standardization of process operation is the only way to improve the efficiency and quality of white cardboard gift boxes. The whole process of boxes is more scientific, orderly and smooth, and efficiency and quality can be guaranteed.
