Description

Die-cutting convex knife die with pressure adjustment function

technical field

The utility model relates to the field of printing and packaging, in particular to a die-cutting convex knife die with pressure adjustment function applied in the die-cutting process.

Background technique

Existing die-cutting dies used in the printing and packaging industry generally include a die-cutting die carrier plate and various die-cutting blades inlaid on the die-cutting die carrier plate. There are also creasing lines arranged horizontally and vertically for producing creases in the outer volume. Of course, a concave-convex die for forming a predetermined concave-convex shape on the die-cut object can also be provided in the outer volume as required. Embossing lines used to form predetermined stripes on the die-cut object and/or characters and/or patterns used to form anti-counterfeit effects on the die-cut object. The traditional method of making die-cutting dies is to use a manually operated electric wire sawing machine on the die-cutting die-cutting carrier board (generally hard wood plywood) to saw out many blade gaps and indentation line gaps, and the blade gaps and indentation lines The gap runs through the upper and lower bottom surfaces of the entire die-cutting die carrier plate, and various die-cutting blades are knocked into the gap between the blades with a rubber hammer, and the blade part of the die-cutting blade protrudes from the working surface of the die-cutting die carrier board The surface of the outer rolling knife mold is formed, and then the indentation line is set in the outer roll, and the concave-convex die, the embossing line and/or the anti-counterfeiting effect on the object can also be set in the outer roll according to the needs. text and/or graphics etc. In order to maintain the firmness of the forming blade, the width of the blade gap is generally made slightly smaller than the thickness of the forming blade (generally 1-2 wires smaller). Using this most traditional manual molding method to make molds, there are The problem of low precision and high labor intensity. The most commonly used molding method now is to use laser cutting instead of manual sawing to make the blade gap and indentation line gap, and then use the same method as in manual molding to inlay the die-cutting blade into the blade gap and press. In the crevice of the trace line, the peripheral rolling knife mold is formed, and then the indentation line is set in the peripheral roll, and the concave-convex die, embossing line and/or used to form anti-counterfeiting on the object can also be set in the peripheral roll as required. Effect text and/or patterns, etc. In short, the method of laser molding is to use laser to make the gap between the blade and the crease line, and the other steps are the same as those of manual production.

Whether it is manual molding or laser molding, the leveling of the indentation line is to first turn the die-cutting die to the back, put the gasket on the die-cutting die, and use a rubber hammer to hit the indentation line that is not in the correct position until it is adjusted normal position. However, this method has the following problems. First, it consumes a lot of energy and time of the laborers; second, there will inevitably be errors based on human observation and manual control alone, resulting in low accuracy of manual leveling, requiring multiple adjustments, which affects use; third, if Improper operation and excessive force can easily damage the indentation line or die-cutting die, or make the indentation line dull.

The die-cutting die needs to be kept in a horizontal state during use to ensure that each position is pressed with the same force as the die-cutting machine, so that the depth of the indentation of the die-cut object can be consistent, and it can be cut smoothly or according to the pre-designed pattern. , text and/or indentation lines are imprinted onto the die-cut object. If the die-cutting die is not kept level, for example if one side of the die-cutting die carrier plate is worn, causing it to tilt towards the other side, it will result in darker indentations, graphics and/or text on one side when it is pressed against the die-cutter , the other side is relatively shallow, resulting in unsightly products. At the same time, due to the strong cutting force on one side, the cutting force is weak on the other side, and the cutting force on the side with low cutting force is not complete, and some parts are stuck, which affects production efficiency. However, in the prior art, the die-cutting die is not leveled before die-cutting or external tools are needed, and the leveling method is complicated.
