Analysis on Safety Screw Fracture of Paper Cutter
The program controlled paper cutter is one of the necessary equipment in printing plant.
Its function is to deal with paper cutting before and after printing. With the development of science and technology, the function of paper cutter is more and more, operation is more and more simple, labor intensity is reduced, cutting accuracy is higher and safer.
In the course of using, there are often the following problems. Next, take the digital display cutter as an example, and simply analyze the reason why the safety screws of the digital display cutter are easy to break.
Lengthening the service life of the paper cutting machine
1, the blade's edge is not sharp enough.
2, the sliding blocks on both sides of the cutter seat wear out.
3, not often to fasten the insurance screws.
4, the installation direction of the insurance screw is wrong.
5, the two ends of the connecting screws are not smooth due to deformation.
6, the blade inserting knife is too deep or the grinding of the knife edge is uneven.
In addition to the above reasons, there are electrical and other reasons. In case of failure, we should solve it in time so as not to delay normal production.
During daily equipment inspection on the production floor, I often notice frequent breakage of safety screws on our program-controlled paper cutters. To resolve this recurring issue, I have summarized practical improvement measures based on on-site maintenance experience.
First, I regularly check the cutting blades and sharpen or replace dull ones to reduce unnecessary cutting resistance during paper processing. I also inspect the slide blocks on both sides of the cutter seat; once they show obvious wear, I replace them in time and adjust the fitting gap to guarantee flexible mechanical movement. In daily maintenance, I manually fasten all safety screws and strictly confirm their installation direction to avoid assembly errors.
Furthermore, I carefully examine the connecting screws. Any deformed screws with rough, uneven ends will be repaired or directly replaced to prevent jamming and abnormal friction. I also make fine adjustments to the blade insertion depth and regrind unbalanced cutting edges, ensuring smooth and even cutting conditions.
Apart from mechanical parts, I routinely check internal electrical components and wiring to eliminate hidden electrical faults. Throughout daily production, I keep track of the equipment operating status, handle minor failures immediately, and avoid continuous overloading and abnormal mechanical stress. These on-site maintenance operations effectively extend the service life of the paper cutter and maintain stable, uninterrupted production progress.
