First, the deviation in die-cutting processing is a common problem in production.

The precision of die-cutting machining is one of the important standards to measure die-cutting quality, and it is an important guarantee for qualified products. EffectPrecision Die CuttingThere are many reasons for machining accuracy, such as mechanical reasons, die-cutting version

ThisBody problems, but also from print problems, operating environment, personnel operation problems and so on. There are different solutions to different problems, and here's an analysis.

Second, the cardboard transmission process, the main transmission chain wear elongation, will directly affect the positioning accuracy before the die-cutting, at this time map 4 die-cutting operation to replace the chain.

Intermittent mechanism wear, resulting in tooth row in the stop or start process jitter, will also affect the precision of die-cutting machining. In this case, there is generally only an impact on positioning accuracy, at this time, the responseSecretary

BreakThe positioning distance of the positioning pendulum before and after the maintenance of the mechanism is too small. Because the length of the chain itself has a certain error, if the positioning distance is too small, the front and rear positioning can not eliminate the chainError

Poor, thus affectingPrecision Die CuttingMachining accuracy.

Third, the adjustment screw of the front positioning pendulum or the cam position of the rear positioning pendulum frame should be adjusted at this time.

1, so that the front and rear positioning frame can move the tooth row 2mm~3mm distance is appropriate on the die-cutting version or the lower die-cutting version of the positioning is not allowed. Long time use of the machine will result in the die-cutting frame or die-cutting bottom plate on the positioning block grinding

So that the mating gap is too large and the die-cutting accuracy is reduced.

2, at this time should replace the positioning block, side positioning plate wear is an important factor to prevent lateral positioning. Because the number of positioning is not enough to make up for wear and tear, it will cause the lateral positioning accuracy to become worse. This

When the side positioning plate should be replaced with paper teeth pressure is too small or uneven.

3, if the active tooth elasticity of the paper teeth due to long-term use and smaller, it will cause the paper in the transfer process slip or fall off, thus directly affecting the precision of die-cutting processing; the pressure between the paper teeth is not

Uniformity may cause the paper to skew in the die-cutting process.

4, at this time should replace the active teeth, in addition, fixed teeth in the horizontal height should also be consistent, otherwise it may also be in the paper when the paper collision or paper after the paper wrinkle, affecting the precision of die-cutting machining

5, the above points are mainly mechanical factors, the need to operate maintenance personnel on the machine to do a good job of timely inspection and maintenance of various components, and replacement of wear accessories to ensure that die-cutting machinery to reach the status.

Iv. Plate-making issues.

1, if there is a problem in the design plate making process, should choose the advanced plate making method, improve the precision of die-cutting version. Or the correction template, mainly the printing and die-cutting position to be positive. Manual

Plate making is prone to deviation, may make the printing position and die-cutting position inconsistent, if necessary, need to re-make the template;

2, the impact of the environment, mainly cardboard deformation or assertion, resulting in "overprinter" is not allowed, thus affecting die-cutting accuracy. As far as possible to ensure that die-cutting indentation and printing in the same operating environment or to ensure that

The identity of the industry environment (G mouth has the same temperature, humidity, etc.).

3, on the glazing and laminating of the impressions to be die-cutting pretreatment, to minimize the impact of paper deformation Liu Mo cutting accuracy. The right paper should be selected to reduce the defects of the material itselfDie-cutting MachiningFactoryAccuracy of

Affect the operator's impact. This includes an entire production process, from plate-making to printing die-cutting, requiring operators to operate strictly according to the process flow, improve production management requirements, and, if necessary,

Operators to train their professional skills.
