12 # saw drive roller rehabilitation

2020-12 # saw drive roller rehabilitation 12 - 09 1, trouble spots: east cutting roll failure 2, problem description: bonding east sawing plate outlet roll as a power roller after long-term wear, drive roller surface is lower than the supporting roller surface, can't play a supporting role, make the plate after cutting transmission failure, big board did not move, use small crane could sew slanting, small board manual pull a time-consuming, laborious cutting workers complain a lot. Plan: to wear and replace damaged transmission roller and bearing seat, change the existing long support roller fixed installation, unable to complete disassembling repair replacement, replace the new support roller length by half, to use the channel to support roller fixed frame, increase the support roller spacing, decreasing the number of support roller, facilitate maintenance support roller replacement, reduce the invalid wear. Implementation: under the condition of no spare parts, considering the simplification of existing transmission roller, removed the unnecessary support roller, using existing wear drive roller to support transmission, the drive roller to welding position, bearing to tighten. To effect: 1, the use of the existing transmission roller wear and tear, implementation support and drive the multi-function temporarily. 2, cutting transmission roller renovation to restore saves artificial plate 30% human consumption can be used in the production promotion, avoid big board pull on safety concerns. 3, 12 # sawing transmission roller renovation to restore and running well, the estimation, can save 20% work lost time, greatly improving sawing fatigue effect, saving time and effort to obtain cutting consistent high praise. （ Emerging case board)
