Failure Analysis of Breaking of Safe Pin in A4 Paper Cutter

- Jul 13, 2019-

In order to ensure the safety of the machine under unexpected overload, we can configure corresponding stable pin components on the pull rod of A4 paper cutter. But sometimes when the resistance value of cutting action is high, the stable pin will crack. At this time, in order to ensure the safety of its machine and other corresponding parts, we should stop cutting operation immediately.


Sometimes when we use A4 paper cutter to cut some scrap papers, because of its uneven sheets of paper, it is too full in the horizontal placement process, and too close to its right wall board. When we cut it, its knife bed will cause its safe selling moment because of the excessive resistance value. Cracking occurred. At this time, we can only replace the parts accordingly, but in fact, it is a very troublesome thing to stop and replace the parts.


Therefore, in order to avoid the above accidents and some unnecessary troubles, we should pay special attention to the consistency of some narrow sheets of paper while cutting them, and at the same time make them not too close to the right wall.
