Folding machine is accompanied by contemporary printing and packaging field of contemporary printing machinery and equipment, contemporary color printing plant usually includes pre-press, printing and packaging, post-press 3 production and processing processes, the key weight-bearing medium for the paper version, because of the prevalence of printing and packaging, in other material media, such as plastic products, fabrics, leather products, metal surface layer these are also prevalent, but the key medium is still to print paper accounted for absolute Ruling printing paper. The face of folding machine failure situation how we analyze because of what makes the folding machine failure? Here’s an analysis together.
1. pull gauge pull paper is not timely or print paper folds.
① cause: pull gauge tension improper. Eliminate the way: to pull the gauge to pull the page as a standard, adjust the pull gauge tension.
② cause: pull gauge pressure cardboard how much is not appropriate.
Exclusion: According to the length of the pull gauge pull paper and print paper thickness, moderate pressure cardboard height.
③ cause: the paper is not properly positioned.
Exclusion: Check the folding machine printing paper in each stage of the transmission link, in accordance with the provisions of the appropriate adjustment to ensure that the paper in a timely manner.
④ cause: the page warps or has a folded edge.
Eliminate the way: to check carefully after the impact of paper, paper loading to level.
2. The page is blocked or torn in transmission.
① Reason: skewed paper catch.
Exclusion: Check the printing paper in each stage of the transmission chain, according to the provisions of the appropriate adjustment to ensure that the paper in time.
② cause: the page has a folded edge or broken, sticky, etc..
Exclusion: Check the collision paper has a loaded paper, remove the broken printing paper.
③ cause: pressure rod, pressure wheel is too low, the page is not smoothly transmitted.
Exclusion: moderate adjustment of the distance between the high pressure lever and pressure wheel.
④ Reason: The transmission line is broken or fractured.
Exclusion: Replace the transmission line belt.
3. The perforating knife is skewed and the folding seam has error.
① cause: folding knife and folding roller position is not appropriate, skewed or not parallel.
Exclusion: Adjust the cutting edge of the folding knife to align with the gap between the two folding rollers, and ensure that the axis line with the folding roller is parallel.
② cause: skewed or obstructed when receiving paper.
Exclusion: Check the printing paper in each stage of the transmission link, in accordance with the provisions of the appropriate adjustment.
