First, use and maintenance
When using, first check whether the fasteners are loose, whether the power supply valve leaks, whether the operation keys are sensitive, then add lubricating oil to the lubrication part, and apply the appropriate amount of high-temperature calcium-based grease to the thin-knife transmission gear, according to the production requirements. Adjust the knife line. Here, we must pay attention to adjust the cutting distance, the slitting blade should be lifted off the sipe before moving, do not interlock with the sipe, otherwise it will easily cause the blade to deform or damage the blade. After the knife position is adjusted, the blade is slowly placed into the sipe, and the depth is 3~5mm. The blade must be centered on the sipe, and it should not be deviated. The two can't touch, otherwise the blade and the sipe will rub against each other. Burned out. The adjustment of the paper guide roller should be on the same line as the indentation line. The paper feed positioning plate should be fastened and parallel to the side line of the device. Otherwise, the cut paperboard is easy to be skewed, resulting in unnecessary wheel marks. After everything is in order, confirm the error and then manually drive the wheel. If there is no abnormality, turn on the power and turn it on.
The quality of the production medium-view blade is sharpened once every 200~50mm, keeping the paper-cutting slits clean and beautiful. At the same time, pay attention to foreign objects such as paper edges, and do not get caught in the blade drive gear to avoid damage to the gears and bearings. After the production is completed, the paper dust and oil on the equipment should be removed in time to keep the machine clean.
After using the ultra-thin knife for a period of time, re-tighten the fastening screws, especially the screws of the fixed blade, otherwise the blade is vulnerable or the flying knife hurts people. The sharpening wheel should also be adjusted in time to make it close to the blade when grinding. When the thickness of the grinding wheel is less than 2mm, the new wheel should be replaced. Replace the outer diameter of the insert when it is less than 225mm. The service life of the blade and the grinding wheel depends on its quality and the number of papers and the quality of the paper. When it is used, it is necessary to select a high-quality brand and a reputable supplier to achieve cost savings and improve product quality.
Second, common fault analysis
1. Difficult to start or unable to start
1 voltage is insufficient; 2 power supply phase loss; 3 circuit fuse is blown; 4 motor is broken; 5 drive wheel fixed key is off; 6 drive gear is stuck in foreign matter; 7 is damaged or the slot gap is too narrow, the blade is card.
2. Automatic shutdown.
1 power off; 2 variable current range adjustment is not correct; 3 drive wheel suddenly falls off; 4 computer input is wrong.
3. The sharpening wheel cannot be lifted freely.
1 Insufficient air pressure; 2 Solenoid valve is damaged; 3 The cylinder that controls the lifting and lowering of the grinding wheel is damaged, or the spring that pulls the return is loose; 4 The grinding wheel and the blade are too tightly attached, which is improperly adjusted by the grinding wheel.
4. Suddenly the machine noise increases and there is rhythm vibration.
1 Each fastener is loose; 2 the transmission gear flies into the paper edge.
Third, the analysis of the reasons for the deviation of common corrugated board
1. The tail of the cut cardboard is skewed.
1The paper feed positioning plate is improperly adjusted; the 2 minute cutter has a blunt degree, which is different from the line speed of other knives; 3 the paper guide wheel is improperly adjusted; 4 improper paper feeding.
2. Cardboard burrs
1 paper knife is blunt, should be polished; 2 blade and sipe overlap too shallow; 3 sipe is wound into the paper edge, paper hair, should be thoroughly cleaned and then turned on; 4 sipe clearance is too large, generally not more than 2.5 Mm is appropriate.
3. The creasing line is broken
1 the original paper is inferior; 2 the pressure line is too deep
4. The pressure line is not straight
1 The pressure line is too shallow, the fold line is uneven, which affects the appearance of the box; 2 the paper feed is skewed; 3 the upper and lower pressure rollers are not adjusted.
5. The cardboard cut is not vertical.
1 The tool holder angle is not correct; 2 the blade is not in the center of the sipe;
