The type of Die Cutting Machine and maintenance
What kind of Die Cutting Machine?
1, round pressure die cutting machine
A roller is equivalent to the impression cylinder, die cutting pressure; the other is a roller knife mold. Roller knife mold has two major categories of wood and metal, the former mainly die-cut thick corrugated cardboard, which has a chemical corrosion or electronic engraving method of processing metal drum knife mold, mainly for self-adhesive labels and trademark cutting , There is also a metal roller knife die is mainly used for high-end long-term products, the use of crush or shear type.
2, round pressure die cutting machine
Round pressure Die Cutting Machine in the market application is very small, there is no professional manufacturer, do not go into here.
3, flat pressure die cutting machine
Flat Die Cutting Machine is currently the most widely used the most common type, but also the most domestic and foreign manufacturers models.
Introduction to the Factors of Die - cutting Die Die
1, Die Cutting Machine die-cutting plate, if the shape of the complex or arranged a lot of live parts, and die-cutting point is very small, very few, it is easy to cause die-cutting when the plate. At this point should be appropriate to increase the number of points, if possible, should be the length of the length of the workpiece and the direction of the paper to keep consistent.
2, if the die-cutting version of the elastic tape (or sponge) is too soft, can not play the paper, will also cause loose version. At this time should use high hardness, good elasticity of high-quality elastic tape (or sponge).
3, the pressure row is too early to start an important reason for the release version. After the die-cutting, when the moving platform is down, although the paper has been elastic tape (sponge) from the knife line, but because the elastic tape (sponge) is generally higher than the knife line 2 to 3 mm, this time if the gripper Start the movement, it will be due to elastic tape (sponge) will still press the paper on the die-cutting floor and easy to tear the paper caused by loose version. At this point should be loose intermittent mechanism and the main shaft of the coupling sleeve to adjust, so that the moving platform from the top dead point down 7 to 8 mm (corrugated die cutting should be 10 to 15 mm), the pressure row began to move.
Die Cutting Machine die-cutting, remember to balance the pressure, die-cutting knife surface layer of a package can reduce the impact, can also be a small shredded paper out. The use of the process to keep abreast of die wear gear gear wear, if necessary, timely replacement gear. Because at the time of processing, the manufacturer intends to make the hardness of the die cutter gear slightly lower than the hardness of the anvil roll gear, so that the wear occurred on the gear of the die cutter. This will avoid frequent replacement of the more expensive and difficult to remove the anvil roll gear. This is very similar to the relative hardness of the roller cylinder and the impression cylinder gear, since the replacement roller gear is easier.
