Characteristics of knife precision engraving machine applied to post-processing of printed packaging box products

Knife precision engraving machine is the core processing equipment for making die-cutting knife plates in the post-process of printing and packaging. It is mainly used for the die-cutting of packaging boxes, color boxes, gift boxes, corrugated boxes and other products. Instead of the traditional manual sawing and milling processes, it directly engraves knife loading grooves, indentation grooves and waste removal positions on the knife plate, and cooperates with die-cutting knives and indentation lines to complete the subsequent die-cutting and indentation operations, which plays a key role in the molding accuracy and production efficiency of packaging boxes, and processes scenes in the post-process of printing packaging boxes.

First, the processing precision is high, which ensures the consistency of the molding size of the packaging box. Printing and packaging boxes have strict requirements on dimensional tolerance, especially for gift boxes and folding color boxes. The dimensional deviation will directly lead to dislocation of paste boxes, loose fastening and offset of sets. The cutter die precision engraving machine has the advantages of high positioning accuracy, accurate engraving slot size, uniform slit width and small position error between the cutter slot and the indentation slot, and can strictly match the design outline of the printed page. The carved knife template and the die-cut paper box after knife loading have square corners, uniform indentation lines and smooth folding, and there will be no batch quality problems such as large and small boxes and misaligned box mouths, which are suitable for high-demand packaging production such as high-grade color boxes, cosmetics packaging boxes and electronic product packaging boxes.

Secondly, it can realize the integrated processing of cutter groove, indentation groove and waste cleaning groove at the same time. The traditional tool die manufacturing needs to separate the milling cutter position, manually dig the indentation position and clear the waste gap, and the working procedure is cumbersome. The precision engraving machine can complete the engraving of cutter groove, indentation groove, waste hole and special-shaped notch at one time according to the design documents. Complex box types, such as special-shaped gift boxes, window color boxes and multi-fold paper boxes, and complex circular arcs, sharp corners and internal buckle structures can be directly output for processing. There is no need for multi-pass sequential processing, which reduces the error caused by manual work, shortens the manufacturing cycle of the knife mold, and can quickly output qualified knife molds when the delivery date of packaging orders is tight, shortening the overall production cycle of the printing process.

Thirdly, adapt to a variety of knife die plates, taking into account the processing needs of different packaging box materials. The packaging box covers white cards, grey boards, corrugated paper and special thick cardboard, and different paper thicknesses correspond to different die plates. The precision engraving machine of knife die can process mainstream knife die plates such as plywood, fiberboard and acrylic board. For thin cardboard color boxes, thin plates are selected for engraving, and for thick corrugated and hard gift boxes, thick plates are selected. The engraving depth is adjusted to distinguish the depth of cutter groove and indentation groove. The depth control of the indentation groove is particularly critical. If the depth is too deep, the paper will be fractured, and if the depth is not enough, the crease of the carton will not be clear. The engraving machine can accurately control the cutting depth, ensure that the indentation is soft, the paper will not burst and crack, and improve the appearance quality of the packaging box.

Fourth, digital operation, convenient version adjustment and adaptation to the trend of multi-variety and small batch packaging. The equipment directly reads the vector file of packaging design without manual drawing and lofting. When the version of the packaging box is modified, the box type is fine-tuned and the local size is changed, it is only necessary to modify the computer drawing parameters and re-export the carving, instead of re-making the knife plate by hand. Faced with the current situation of small batch, multi-order and frequent change of box type in printing industry, it can quickly make a knife mold, greatly improve the proofing efficiency of new products and reduce the cost of revision. The same equipment can quickly switch different box processing, with high flexibility, which is suitable for multi-category order production mode of packaging factory.

Fifth, the stability of the finished product of the knife die is good, and the yield of the subsequent die-cutting process is improved. The inner wall of the carved knife groove is flat and smooth, and the blade is tightly embedded and attached, and the blade is not easy to loosen and shift. In the process of mass die cutting production, the precision of the knife die decreases slowly, and its service life is better than that of the traditional manual knife die. Die-cutting production runs less, reducing die-cutting running, uneven trimming, indentation deviation and other defects. At the same time, the consistency of carving groove position is good, and the operation of knife loading is simple, which reduces the manual technical threshold of knife mold masters and reduces the dependence on senior technicians, which is conducive to the standardized production of packaging enterprises.

Sixth, effectively reduce the comprehensive production cost of the latter. The traditional manual die making takes a long time, and the labor cost is high, so it is more difficult to make complex boxes. Automatic machining of precision engraving machine greatly reduces man-hours and doubles the efficiency of making knife dies. The quality of the die is stable, the rejection rate in the die-cutting stage is reduced, and the paper loss is reduced. Although the equipment has been invested in the early stage, it can shorten the production cycle of the knife mold, reduce the rework loss and comprehensively reduce the processing cost of the packaging box under the condition of continuous multi-order production.

Generally speaking, the precision engraving machine of knife die is applied to the back of printing packaging box, and its core advantages focus on high-precision integrated processing, digital flexible production, and stable and reliable finished knife die, which solves the pain points of poor precision, long cycle and difficult processing of complex box-shaped traditional manual knife die, adapts to the development needs of multi-variety, high quality and fast delivery in the current packaging industry, and becomes an indispensable processing equipment for color boxes and gift box manufacturers.
