Tell you in the operation of the Manual Die Cutting Machine to keep in mind a few questions
Manual Die Cutting Machine accuracy is not high or die-cutting indentation position is not accurate in the actual use will cause important impact, affecting the actual production and processing technology, can no longer have important aspects of the characteristics and value, Improve the imperfect areas, so that it has a good space for development and value, so that it has efficient production and use of power in the use of the industry to show good performance and trends.
Laser plate-making accuracy is relatively high, the design and cutting by the computer and mechanical completion, suitable for high-grade packaging die-cutting. All the Manual Die Cutting Machine itself will produce precision error, to improve die cutting indentation accuracy, we must choose high-precision Manual Die Cutting Machine. Should try to ensure that die-cutting indentation to ensure that the work environment of the same (that is, the same temperature, humidity, etc.).
Manual Die Cutting Machine die-cutting indentation line location and print product location does not match, the reasons for this failure are the following:
1, Manual Die Cutting Machine die cutter version of the production process error, can not absolutely achieve the ideal die-cutting indentation position.
2, cardboard Miao mouth different rules. Manual plate-making way to the plate of the technical level of high, plate-making machine by the technical level and experience of the plate and other factors, suitable for precision is not high in the short version of the packaging.
3, Manual Die Cutting Machine die-cutting indentation and printing of the grid is not correct, the solution is based on product requirements to re-correction die-cutting version, sets of printing and die cutting indentation, but also by the transfer paper Side positioning rules or pre-positioning rules to correct the die-cutting indentation and printing grid registration. Manual Die Cutting Machine die-cutting indentation and printing the working environment will cause different cardboard fiber deformation or extension, but also make die-cutting indentation are not allowed.
Now Manual Die Cutting Machine die-cutting version of the production methods are mainly hand-made plate and laser plate two. Therefore, to get a good precision die-cutting machine precision, you must choose to improve the older plate-making way; such as check the paperboard Miao mouth specifications error, it may be Manual Die Cutting Machine after the positioning (also known as the second positioning) Too small, can be adjusted by positioning, increase the positioning after the distance to solve.
Resulting in the accuracy of the Manual Die Cutting Machine
One, on the die-cutting or die-cutting version of the positioning are not allowed.
The use of the machine for a long time will cause die-cutting frame or die-cutting plate on the positioning block wear, so that the gap is too large and lead to Manual Die Cutting Machine to reduce the accuracy. The positioning block should be replaced at this time. Side positioning plate wear is an important factor in the side positioning is not allowed. As the positioning of the dialing is not enough to make up for good wear, it will cause poor positioning side positioning accuracy. Replace the side positioning plate at this time.
Second, before and after the positioning of the pendulum positioning distance 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 chain error, thus affecting the precision of the Manual Die Cutting Machine. At this point should be adjusted before the positioning of the pendulum screw or post-positioning pendulum cam position, so that the front and rear positioning frame to stop the teeth 2mm ~ 3mm distance is appropriate.
Third, gripper pressure is too small or uneven.
If the gusset's active dental elasticity becomes smaller due to long-term use, it will cause the paper to slip or fall off during the transfer process, which directly affects the accuracy of the Manual Die Cutting Machine. The uneven pressure between the grippers may cause the paper to Skew in die cutting process. At this time should change the active teeth. In addition, the fixed teeth in the horizontal height should also be consistent, otherwise it may be in the gripper paper collision or gripper paper wrinkles, affecting the accuracy of Manual Die Cutting Machine.
Fourth, cardboard transfer process, the main drive chain wear and tear elongation, will directly affect the positioning accuracy before die cutting.
At this point to replace the chain. Intermittent mechanism wear, resulting in tooth row in the stop or start the process of jitter, will also affect the accuracy of Manual Die Cutting Machine. In this case generally only affect the positioning accuracy, this time, should be timely maintenance.
