The Best Plan of Paperboard Production--Three Elements of Paperboard Quality" (2)

External suction corrugating machine operating procedures and troubleshooting methods

â—† Open air compressor air supply;
â—† After the air pressure reaches the specified requirements, start the host to run at low speed, then warm up the equipment and drain the condensate at the same time;
â—† Open the inlet valve and open the return bypass valve to drain the condensate quickly. After a few minutes, close the bypass valve and use the trap passage to drain the condensate.
â—† Open the plastic valve to enter the plastic, pay attention to observe the amount of glue, close the valve after the rubber hits the position, and at the same time, the rubber roller motor starts to drive the idle roller to run:
â—† When the temperature reaches the production requirement, the paper is introduced into the pressure roller through the preheating roller to pressurize the corrugating roller. The corrugated paper is introduced into the corrugating roller as required and the adsorption fan is turned on to induce the wind. After the corrugated paper enters the corrugating roller, the glue is started. The switch performs squeegeeing, at the same time, the rubber roller motor stops running, immediately after the corrugated paper bypasses the corrugating roller, it is pressurized to the pressure roller, and the formed single-faced corrugated paper is introduced into the lifting scraper frame and transmitted to the overpass;
â—† Adjust the paper holder to align the paper with the paper, and adjust the brake of the holder to ensure that the paper has sufficient tension;
â—† After everything is normal, increase the speed to normal production;
â—† In normal operation, if the downtime is long, the paste tray will exit the machine and the glue roller will run empty to prevent the corrugating roller from stopping for a long time. Because of the heating, the bending deformation is prevented;
â—† After work, start cleaning the machine. Corrugated roller on the N32 oil empty vehicle running. Adsorption fans, shut down, cleaning plastic discs and rubber rollers, plastic discs and rubber rollers must be cleaned and dried. Note that car wash cold water must not be sprayed on the corrugating roller to prevent deformation of the corrugating roller;
â—† The cleaning of the suction hood is cleaned once every half-month, the lid of the suction hood is opened, and all foreign materials are cleaned;
â—† Observe whether there is oil and water in the triplets. No oil is needed to refuel, and water must be drained in time.
â—† The corrugating roller wears for a period of time. Especially when using narrow-width papers, the middle wear is more severe. Then use a wide-format paper and bubbling in the middle. Now grind the two ends with grinded sand. If the wear is severe and the height does not meet the requirements, it is necessary to re-polish the corrugating roller, or replace the new corrugating roller;
â—† Always check if the bolts on the corrugated conveyor frame on the top of the corrugator machine are loose, do not drop onto the corrugating roller to prevent the corrugating roller from being damaged;
â—† Check whether the scraper roller is always glued, and adjust the scraper plate if it is glued.
â—† Observe whether the movement of each cylinder is flexible and reliable, and whether it can maintain pressure; otherwise, maintenance should be carried out. When using narrow-width paper, the baffle plate should move to the middle, consistent with the width of the paper web, and observe whether there is glue on the pressure roller, and if necessary, remove it in time;
â—†Regardless of adjusting any parts, it should be stopped to prevent personal and equipment accidents;
â—† The suction slot on the main corrugated roller is cleaned once every quarter to prevent foreign matter from affecting the adsorption effect. It must be stopped when it is removed to prevent personal accidents.

W02E adsorption corrugating machine adjustment method

Corrugated roller parallel adjustment: In the two corrugated roller between the left, middle and right parts put 15A fuse, to the corrugated roller plus 0.2Mpa ~ 0.4Mpa pressure, the handlebar handlebars wire out, check the left wire, Whether the thicknesses of the middle and right three faults are the same or not, and whether the thickness of the two side surfaces of the tooth shape are the same, which is inconsistent with the adjustment of the eccentric mechanism until the same.

Adjust the gap of the suction hood: use a feeler gauge or corrugated paper to adjust. Open the suction cover and adjust the gap between the main corrugating roller and the front windshield. The clearance is generally between 0.1mm and 0.2mm. Adjust the gap between the pay-per-wale roller and the suction hood rear baffle. This gap is generally 0.3mm-0.5mm (in the case of not grinding the roller, the smaller the better). After adjustment, use a corrugated paper to wrap the corrugated roller. If the opener is used to see the effect of adsorption, most of the paper can be sucked on (cold test), and the steam passes the test (hot test).

The gap between the rubber roller and the corrugating roller: The gap between the main corrugating roller and the rubber roller is generally 0.1mm~O.15mm, and is measured with a feeler gauge. Adjustment method: There is a set screw on the baffle between the top roller and the main corrugated roller, which is tightly tightened with a nut. Loosen the nut and turn the screw. Measure the gap with a ruler. After the two sides are aligned, tighten the nut. If it is an electric adjustment gap, you can achieve the required digital input gap (note the location of the photoelectric switch).

The gap between the rubber roller and the rubber roller is the same as above.

Pressure roller and corrugating roller gap: It is necessary to ensure that there is a gap in the thickness of corrugated paper in order to ensure that the liner and roller are not crushed, and the positioning screw is adjusted well.

Since the overcoating roller is equipped with an overrunning clutch, it is necessary to prevent the water from squeezing to the middle, the machine and the clutch when the brush is being driven. Otherwise, malfunction may occur.
