Many friends in the use of die-cutting machine, I found sometimes the accuracy of the phenomenon of decline, then what causes this phenomenon is it? How do we solve this problem? Xiao Bian gave an analysis.

First, the upper or the lower die-die-positioning allowed. Machine prolonged use can cause die-box positioning block or die wear on the floor, so that the gap is too large to reduce the cutting accuracy. It should replace the positioning block. Side positioning plate wear is an important factor causing side positioning inaccurate. Due to the amount of targeted toggle good enough to compensate for wear and tear, it will cause side positioning accuracy deteriorates. It should replace the side positioning plate.

Second, the front and rear positioning swing frame positioning distance is too small. Because the length of the chain itself has a certain degree of error, if the positioning distance is too small, the front, the chain can not be eliminated after positioning error, thus affecting the cutting accuracy. You should adjust the positioning before and after adjustment screw pendulum swing frame rack or positioning of the cam position, the spacers can toggle back and forth so that the tooth row 2mm ~ 3mm distance is appropriate.

Third, the gripper pressure is too small or uneven. If the activities of the gripper teeth elasticity due to long use becomes small, it will cause a paper slip or fall off in the transfer process, which directly affect the cutting precision; uneven pressure between the gripper may cause paper die the process is skewed. It should replace the activities of teeth. In addition, the tooth fixed at the level it should be consistent, otherwise it is possible to produce paper gripper after collision or wrinkled paper, affect the cutting precision when gripping.

Fourth, cardboard transfer process, the main drive chain wear elongation, will directly affect the positioning precision die before. This time to replace the chain. Intermittent wear mechanism, causing tooth row at stopping or starting the process of chattering occurs, will affect the cutting accuracy. In this case generally have an impact on the positioning accuracy, this time, to respond to timely maintenance.

These four points are die-cutting machine accuracy is not high mechanical reasons, operation and maintenance personnel need to do maintenance on the machines, timely maintenance checks to ensure the optimal functioning of the state die-cutting machine.
