Analysis of chain failure in printing process of offset press
Due to the different requirements for paper, forms, books and periodicals printed by offset presses, different sizes, thicknesses and thicknesses, the machine needs to be adjusted accordingly for different papers. The following examples analyze: In the recent process of printing bills, there was a case where there was a blanking phenomenon every few sheets when starting fixed-speed printing. The paper that has been dropped is stained with oil in the machine and can no longer be used, and it will affect the normal paper passing behind. At first, I think it was caused by the instability of the feeder feeder or the failure of the double-sheet controller. However, it was found that part of the feeder feeder and the gripper paper of the feeder were very stable and normal. Go back and continue checking the chain gripper. All the chain grippers are numbered in rows, and the numbers are printed on the "spectacle case" on both sides of the chain grippers with white ink in sequence, and they are printed normally. After careful observation, they are found to be very regular. Empty sheet. After stopping, the third row of chain teeth was moved and inspected. It was found that this row of chain teeth had little contact with the dental pads and the gripping force was also small. Some dental pads were more seriously worn. In this way, the paper will be stable, and the paper will naturally drop out during the high-speed operation of the machine. Shut down carefully and carefully repair one by one, the adjustment gripping force of the adjustment gripping force, the replacement of the dental pads should be replaced with new ones. After such an adjustment, the fault was completely eliminated. 3D Panel Fence
