Notices for Daily Maintenance and Maintenance of Single Side Machine

The maintenance degree of paperboard production equipment affects the outage rate of equipment. The reason is simple: the more downtime, the longer downtime, then the production efficiency is very low. In many enterprises, the shutdown time of cardboard line can be as long as one hour a day. If you work for 10 hours, then only 9 hours are in production, which is equivalent to only 90% of the effective production time. The effective time of the better enterprises can reach 98%, the number of downtime is only 1-2, and the downtime is single digit.

Single-sided machine is the key single machine in the whole production line of corrugated board. Its maintenance and maintenance not only affect the production efficiency, but also directly affect the quality of corrugated board produced. Today I will focus on the maintenance of single-sided machines.

Before going to work every day, the refueling place should be refueled, especially the support axle of corrugated roll and pressure roll. Check whether there is foreign body on the corrugated roll, if there is timely cleaning.

Pass in steam, open bypass valve, release condensate, close bypass valve after 1-2 minutes. If the bypass valve has been opened the previous day, close the bypass valve before opening the steam.

The machine starts to preheat, add N32 oil to the corrugated roll, start the air compressor, and press 0.2 MPa or so, the machine starts to run empty. Pay attention to the pressure roll and strictly prohibit pressure. When the temperature reaches, the paste is input, the wind-suction motor is turned on and the paper is input.

After both sides of the paper are input, the paste is put on to make it glued, and the pressure roll is pressurized to start working normally. In normal operation, if the shutdown time is long, the paste disc withdraws from the machine and the top roll runs empty, preventing the corrugated roll from shutting down for a long time and bending deformation due to heating.

After work, start cleaning the machine. N32 engine oil empty car running on corrugated rollers. The absorption fan shuts down. Clean rubber disc, rubber scraper roll, rubber scraper roll, rubber disc and rubber scraper roll, rubber scraper roll must be clean, pay attention to car washing cold water must not be sprayed on the corrugated roll, to prevent corrugated roll deformation.

Other non-routine maintenance and maintenance considerations

The absorption hood is cleaned up every half month, the upper cover of the suction hood is opened, and all foreign bodies are cleaned up. Pay attention to the observation of air compressor water to be released in time.

Observe whether there is oil in the air compressor every day, do not refuel in time, change oil regularly.

Corrugated rollers wear out over a period of time. Especially when narrow paper is often used, the wear in the middle is more severe. Then use wide paper and foam in the middle. Then use abrasive sand to grind both ends. If the wear is serious and the height can not meet the requirements, the corrugated rollers should be repaired or replaced.

It is necessary to check the bolts on the corrugated conveyor rack on the top of the tiling machine regularly. Don't fall on the corrugated rollers to prevent corrugation from crushing.

Always check whether the scraper roll is taped. If the tape is taped, adjust the scraper.

Often observe whether the movement of each cylinder is flexible, reliable, and can ensure the pressure, otherwise it needs to be repaired.

When using narrow sheet paper, the rubber baffle should move to the middle, the same as the width of the paper, and observe whether there is glue on the pressure roll, if any, it should be removed in time. Any part of the adjustment should be parked to prevent personal and equipment accidents.

The suction trough on the main corrugated roll is cleaned up quarterly to prevent foreign bodies from affecting the adsorption effect. When cleaning, the machine must be stopped to prevent personal accidents.

The lubricating oil in the gearbox is filtered once a year and supplemented to reach the middle of the oil standard.

The main and auxiliary corrugated rollers, pressure rollers and rotating preheating rollers are lubricated with high temperature grease (above 200 C). Oiling is checked once a week.

Check the parallelism of corrugated rollers, pressure rollers, top rollers and scraper rollers once a week, and adopt "copy paper method" and "lead pressing method". Parallelism is usually 0.03 mm. If not, it should be adjusted in time.

Measure the temperature of the main and auxiliary corrugated rollers, pressure rollers and preheating rollers once a week. If the temperature difference between upper and lower, left and right is large, the siphon may be damaged and should be replaced in time.
