Sanding Machine Common Fault Analysis And Cleaning
During operation of the machine, often present some problems, but these should be clean in time, but if it weren't handled, may affect the production and added costs. This requires operator action is necessary regulations, skilled operation, remove in a timely manner. When there's something wrong with discovery was not severe, but if not done properly, there'll be a myriad of problems, severe impact production. Under the sanding machine common fault analysis.
• Abrasive belt deviation, usually because of improper adjustment led to, the normal belt swing should swing for 15-20mm, set the frequency of 15-20/min, moderate swing speed and swing into the assumed speed of. If in an irregular situation, for a long time, perhaps deviation appearances, especially swing put speed is not common, are more likely to lead to abnormal outages appearances; damage photoelectric switch, solenoid valves, swing cylinder corruption. Poor cleaning, high concentrations of dust can affect the photoelectric cell operation, lead belt running deviation; shall promptly replace damaged parts, improved results.
• Limit failure, belt side limit switch, when swing belt failure, when running into the side, touch the limit switches, belt loosened, active suspension of the main motor, can be useful to maintain the belt. Once the failure limit can cause damage to the belt, friction rack-Mars, and even cause a fire. Thus limit switch should always check action is solid.
• Sand with up wrinkle, and sand with once up wrinkle on cannot again using, usually led to sand with up wrinkle has three species may: sand roll and Zhang tight roll wear formed, grinding wants to, and amendment roll; sand with damp soft introduction recommends wrinkle, can selection drying dried, method processing; sand light machine long-term not using sand roll appearance rust rough, sand with swing difficult introduction recommends more, now should roll tube except rust or with more fine sandpaper polished.
• Abrasive belt cracking, cracking primary belt running deviation of belt or belt wear was not replaced in time, or sanding, the load is too large, or in the process of sanding, hard objects, or the belt itself quality problems. Should try to prevent cracking, or may cause a fire. When current anomalies, should investigate the sanding belt is not blunt, if should be replaced in a timely manner.
5. plate deflection, spin, bounce, Sander adjustment request adjustments to delivery on roller pressure spring two-thirds (remaining one-third), transported on rolls and transportation roller distance should be less than after the slab thickness 1.5mm or 1mm, or result in slab deflection or skidding. Serious cause rebound, which may hurt safety.
