Safe operation

(1) plug curtain (sail) fabric joints, should first signal, notify the material, and then plug, the host before and after the operator to work closely together, plugging the material is not allowed to wear gloves, playing slow blocking car speed.

(2) curtain calendering is strictly prohibited when anyone in the tension roller casually walking between.

(3) feed with a fist pheasant, not allowed to use fingers, to prevent fingers rolled into.

(4) rubber material piled up on both sides of the rubber blocking plate, should be hooked out of the iron hook. When adding rubber in the lower roller, it should be top with special tool, and it is forbidden to use hand.

(5) When measuring the thickness of cord fabric, the hand should be 1500px away from the rollers to prevent the hand from rolling in.

Maintenance

(1) Check all electrical contact signals and safety devices, should be sensitive and reliable.

(2) Check all lubrication parts and add them in time if found insufficient.

(3) Adjust the hydraulic pressure and lubricating oil to the required temperature according to the ambient temperature.

(4) Before starting the main machine of the calender, the lubrication system and hydraulic system should be started first to make sure that the pressure, temperature and flow are normal before starting.

(5) Check the roller distance of the calender for debris and keep the proper roller distance.

(6) Check the transmission parts for debris and whether the safety guards are firm.

(7) Check the bolts of each part for looseness.

(8) After the calender is finished working, adjust the axle crossing device to the "zero" position, enlarge the roller distance, and then take down the rubber, and stop the machine only when the roller temperature drops to below 60℃.

(9) the whole unit shut down, close the valves and power sources, the cooling system after the end of the week after the cooling system in the water off, remove the machine surface stagnant oil and debris, etc..

(10) Clean up around the machine.

Precautions

(1) system before the machine is not started, the oil pump first run for 10min. after stopping the machine should continue to run for 10min, so that all the lubricating oil back to the tank.

(2) Pay attention to the temperature of the oil return from the roller bearing of the rubber calender, if it exceeds 80℃ or if the temperature is found to have a drastic increase, stop the machine immediately to check the reason.

(3) Roller heating must be carried out slowly in low-speed operation, the heating speed is 0.5℃/min (30℃/h) when it is below 100℃, and 0.25℃/min (15℃/h) when it is above 100℃.

(4) Rubber calender roller temperature above 70 ℃, not allowed to stop, need to slowly reduce the roller surface temperature to below 60 ℃ before stopping.

(5) When using the pitch adjustment device, move the bearings at both ends at the same time as far as possible. If the difference between the two ends of the roller distance is large, the small end should be enlarged to the same as the other end and then adjusted together.

(6) When adjusting the roller pitch below 1mm, keep the roller pitch with material to avoid touching the roller and damaging the roller.

(7) When a fault occurs during the operation of the machine, the emergency stop device should be pulled immediately to cut off the power supply and stop the operation.

(8) After the machine has finished working, it should immediately enlarge the roller distance, remove the residual material, reduce the roller speed, and slowly cool down to 60 ℃ before stopping. With roller temperature control, the speed of temperature reduction is: above 100 ℃, not more than 0.5 ℃ / min; down to below 100 ℃, not more than 1 ℃ / min.

(9) Before stopping, for the calender equipped with shaft crossing device, after the roller turns to low speed operation, the roller shaft crossing device needs to be returned to zero position.

(10) When using roller shaft crossover, do not perform separate end spacing to avoid damage to the machine.
