When the automatic die-cutting machine is producing products, why does the product size appear deviation and vary in size? The most common one is that the carton rocking cover is big here and small there after printing and die-cutting. What is the reason? Generally speaking, the size of automatic die-cutting machine is caused by the following two problems.

Automatic die cutting machine

First, the speed difference caused by the automatic die-cutting machine stick

Causes of speed difference: When the pressure of the automatic die-cutting machine is too high, the cardboard slows down when it is transported, and the speed difference will occur when the upper and lower sticks are fast and slow. When the corrugated board just entered the die-cutting, the die-cutting pressure began to increase. At this time, because the board just entered, the whole rotation speed was even, so the size of the first board was correct. Because the cardboard is under heavy pressure for a long time, the rotation speed of the upper and lower sticks changes, so the size of the cardboard at the tail changes, resulting in different sizes of the upper and lower rocker covers.

Secondly, the diameter of the whole drum becomes smaller due to the wear of the Youli rubber pad, which leads to the inconsistency of the upper and lower speeds.

When the circumference of die-cutting rubber cushion changes, the die-cutting size of carton will also change, so when the die-cutting rubber cushion wears too much, it must be ground or replaced to ensure the die-cutting size accuracy. Thus, in the process of die-cutting production, the selection of die-cutting rubber mats is very critical, and life and quality should be considered comprehensively when purchasing die-cutting rubber mats. The faster the die-cutting rubber pad wears, the greater the probability of your accuracy error. Therefore, the pressure of die cutting should be reduced as much as possible in operation, which is beneficial to the life of the mold and Youli rubber pad.
