Sanding machine while it is running, and often fails, most failures can be ruled out, but if not handled properly, could affect production and increased costs.This requires the operator to be aware of common faults, rapid response, ruled out. Some fault found was not serious, but if not managed properly, it couldlead to a major fault, severely affecting production.
1 wrinkled, belt: belt once wrinkles can no longer use, generally causingwrinkle belt there are three possible. A sanding roller and tension roller inthe vertical plane is not parallel to the pad at the Center bearing cylinderrequirements and correction. Second, raised sand with a damp soft wrinkled,drying drying and other approaches can be adopted. Third, long time do not usesanding abrasive roller rough surface rust, abrasive belt swing difficultiesthrown up, rust or the roller with fine sandpaper.
2, sand-belt: belt deviation of belt fractures due to sand, abrasive beltgrinding or blunt did not promptly replaced, or sanding, the load is too largeor hard objects in the sanding process, or the belt itself caused by qualityproblems. Abrasive belt breaking should be avoided, as it may cause a fire orexplosion. When exceptions occur when sand roller counter currents shouldobserve whether the belt is blunt, if should be replaced immediately.
3, the deviation of the belt: usually caused due to improper adjustment, normalbelt swing should be a 15-20mm swing, oscillating frequency: 15-20 beats/min,moderate swing speed and swing put speed consistent. If you are in an abnormalstate, for a long time, possible deviation phenomenon, especially into put speedconsistent, easily trigger off. Deviation of the belt may be a photocellmalfunctions, swing swing cylinder valve or damage caused. Poor suction, highconcentrations of dust can affect the photocells work correctly, and may alsocause sanding belt deviation.
4, limit failure: sanding belt on both sides of limit switch, when swing beltfailure, when snaking to one side, touch the limit switches, belt loosened, mainmotor stops automatically, can effectively protect the belt. Once damages limitfailure may cause the sanding belt, friction rack-Mars, and even cause fires andexplosions. So should always check the action of the limit switch is reliable.
5 oil pressure gauge pressure abnormal, lower rack: uses the hydraulic liftbefore the next rack side there is oil pressure gauges, oil pressure gaugepressure for normal conditions 70-90kg/cm2, and relatively stable. If thepressure is frequently fluctuating between 70-90 kg/cm2, shows that the liftcylinder may leak or leaks, if pressure less than 70 kg kg/cm2 hydraulic systemdoes not normally require adjustment. If there is no pressure switch is notpressed in place. Sanding machine pressure gauge in non-normal, there may be asanded dimensionally unstable or fragile, affecting quality of sanded.
6, into the plate deflection, spin, bounce: Sander to adjust roller pressure spring loading adjustment required in the two-thirds (remaining one-third),conveyor rollers and conveyor rollers interval should be on 1.5mm or 1mm lessthan through the slab thickness, otherwise it will cause a deviation of the slabor skidding. Serious caused a backlash, and that could hurt safety. Sandingmachine
7, after changing the sanding belt sanding plate size changed: Sander boom atthe time of release or locking locking block, volatile position, normal should be less than 0.5mm. If it is too large when the locking block while lockingcantilever, the locking force of cantilever repeatability of differences thatcan make the difference, sanded size fluctuations caused by, directly affectsthe sand-sanding machine cutting precision. When the cantilever when the erroroccurs (over 0.5mm) twist lock fixing bolts should be adjusted properly,replacing the belt at the same time, the locking block locking should beconsistent.
Sanding machine cleaning and maintenance
The first life is the maintenance of the machine, a machine to normal first thing to do is care and maintenance, the following must be done:
One, clean
Fixed during the cleaning job:
Daily
· Clean and dust shield dust collection pipe.
· Clean plate and blank rounds ... Use a scrubbing brush and a rag.
· Clean the conveyor belt · The water in discharge air compressor waterfilter.
· Clean glass surface ... Use a lens cleaner and a soft cotton cloth.
· Clean machine inside and around the accumulation of dust.
Every week
· Clean dust on the elevating screw and chain.
Second, the maintenance
· Security systems before starting the machine, be sure to test all safetyswitches are normal.
Weekly inspection and testing the brake system and avoid the "emergency stop"cannot be executed.
· The main motor drive belt properly adjusted will increase transmissionefficiency and service life of the belt, for checking the time reference:
· First check: new machines or replacement of the product after 4 hours of use
· Second time: interval 1 day after the previous check
· Third: every 3 days after the last check
· Fourth check: interval last checked 5 days after
· Fifth check: every 7 days after the last check
· After the inspection: every week
Third, parts inspection
· A conveyor belt
Machine in use for some time after the conveyor belt will have a certain degreeof wear and tear. If you wear influence into the sanding quality, so we have touse grain 40 or 60, sandpaper, conveyor belts for leveling grind grind. If theband has been on several occasions when ground and a raised pattern has a nearperfect loss, it is recommended that replacement products.
· The rubber wheel
When the rubber wheel has minor wear, can use a precise thickness and flat Board(w: 300mmxL: equivalent to width) and posted 60 sandpaper in the clay, andgrinding the tire surface correction.
