1: Phenomenon: When stepping on the foot switch during semi-automatic operation, the slider moves downward and then moves up, but not right. This phenomenon occurs because the proximity switch at the upper left of the vertical slide is not sensed or there is a problem with the proximity switch.
Solution: Adjust the proximity sensor above or better.
2: Phenomenon: The tabletop does not suck air. The cause of such failure is that the suction motor burns.
Solution: The contactor that controls the operation of the motor is damaged, the suction motor rotates, but the control of the suction solenoid valve failure, the suction selection switch failure, the solution is repaired or replaced.
3: Phenomenon: The rise speed of the vertical slide is slow, because the bearing of the vertical slide is free of oil or the cylinder piston is worn, and the magnetic collision causes the axis to bend;
Solution: replenish oil, replace piston password, and adjust the axis.
4: Phenomenon: When semi-automatic working, stepping on the foot switch slides down, and then rises after releasing.
Solution: This phenomenon is generally caused by the proximity switch on the left side of the slide seat being damaged or disconnected. The solution is to replace the proximity switch or switch on the switch.
5: Phenomenon: automatic, semi-automatic start does not drop. This type of failure occurs when the proximity switch on the right side of the slide carriage is faulty or not sensed, the selector switch is faulty, or the single-action switch interlock point is damaged.
Solution: adjust the proximity switch induction or replace the right side proximity switch, replace or repair the selector switch and single-action switch.
6: Phenomenon: When semi-automatic, the foot switch is not acted on, but it will act immediately.
Solution: The cause of this kind of fault is mostly caused by the damage of the foot switch or the short circuit of the foot switch socket, and the other is the problem of the manual start button switch. The repair method is to replace the new switch, socket, button switch or dismantle the related damaged parts.
7: Phenomenon: all manual and semi-automatic operations are disabled, and the power light is on. Solution: The cause of this type of failure is that the low-voltage side fuse is blown out, no gas source enters, and all the solenoid valves are faulty.
Solution: replace the low-voltage side fuse and check whether the pressure reaches 4-7kg / cm. All the solenoid valves have a small fault, and most of them are disconnected.
8: Phenomenon: When semi-automatic work, the vertical slide seat is lowered by stepping on the foot switch, and the printing seat does not move after moving to the left.
Solution: The reason for this failure is that the proximity switch on the left side of the horizontal slide is not sensed or there is a problem. The solution is to adjust the sensing point of the left proximity switch or replace the proximity switch; there is also a micro switch in the foot switch that is stuck and does not move, which can also cause this fault. The solution is to adjust, repair or replace the micro switch in the foot switch.
9: Phenomenon: the work surface does not suck, the reason is that the solenoid valve controlled is damaged or the internal block is damaged.
Solution: Replacement repair.
10: Phenomenon: Automatically unable to start, such failure is that the micro-branch switches of the upper and lower cylinders are normally closed, the contact cannot be turned on or the timer is damaged.
Solution: Repair the micro switch or replace the timer.

The use of the paper cutter must be carried out according to the regulations. What should I do? Let's take a look together with paper cutter manufacturers!
1. The safety ground wire must be connected.
2. The two-handed linkage button. When cutting paper, you need to keep pressing the lower knife switch with both hands. You cannot release it until the blade stops moving. When the paper presser returns to the highest position, you can release the two-hand switch. The starting point of this design is to protect the safety of the operator, in line with the people-oriented design concept.
3. The paper-pushing system is a slotless double guide rail, and it is not easy to tilt and shift from left to right, but also pay attention to not adding a large impact force to the paper pusher.
4. The paper cutting drive system of the paper cutter is electromagnetic clutch, gear reduction transmission, usually pay attention to keep the gear box clean, if there is paper debris, it should be cleaned in time.
5. The electromagnetic clutch is powered by carbon brushes, and the cutter should check the wear and power transmission of the carbon brush before going to work.
6. Pay attention to the lubricating of the paper screw, and if possible, check the clearance of the screw nut every quarter.
7. The back lever of the knife has been strengthened. For the upper part of the bar bushing, oil-free bearings are used (copper-based inlaid composite bearings, which can be heavily loaded without oil. Copper is centrifugally cast and has a hardness of hb245. Bite!) Maintenance is simple, as long as you occasionally add lubricating oil from the pin shaft of the knife back (nozzle is at the back), the pull-down rod uses powder metallurgy bushing, plus a drip-type oil cup, long service life and large bearing capacity.
8. The hydraulic system is designed and produced with reference to the German Bora knife system, and the system works stably. Because of the bad working environment, the valves of the hydraulic system of the machine are occasionally blocked, causing the paper presser not to press down. Don't panic if the paper presser does not press down. Remove the valve and clean it according to the instructions.
9. The clutch clearance also needs frequent attention. The surface of the brake pads must not be oily. If there is oily contamination, the source of the oily contamination should be considered. If there is too much oil stored at the front gear, stop the refueling and clean the oil sump.
10 When the operator releases the lower knife switch at any time, the blade will stop immediately. We require the operator to strictly abide by the operating rules to operate the machine.
11. Regularly check the integrity and reliability of the encoder and the forward and backward switches. The hydraulic system is relatively sensitive to hydraulic oil, please add lubricating oil according to the instructions. Generally, No. 68 is used in summer, and No. 46 wear-resistant hydraulic oil is used in winter. When replacing hydraulic oil, pay attention to clean the oil pool.
After reading the above, you now know how to use the paper cutter!
First look at which side is slanted, and then push the adjustment screw of the paper pusher forward on the wide side. If it is a manual machine, loosen the screw under the scale rod to adjust the scale rod, and then fix the screw.
The cutting of the paper cutter depends on the blade on the paper cutter, which is one of the important parts of the paper cutter. The sharpness and service life of the cutting blade greatly affect the working efficiency of the cutting machine. When using a paper cutter, pay attention to safety, so safe operation is required. Paper cutter is one of the necessary equipment for printing plants, it is mainly used for cutting paper. Nowadays, mechanized operation is generally adopted, which reduces the labor intensity of workers, and paper cutter is one of them.
What is the purpose of the paper cutter? Paper cutter is used to cut the paper before and after printing. The cutter is easy to operate and has no special requirements on the environment. As long as the power is supplied, it can work normally.
After the cutter is used for a long time, some problems will occur more or less, such as the cutter does not move, the abnormal noise, and the paper pusher does not move. This is a recurring problem encountered by printing companies. How to deal with it is not good, which is very unfavorable to printing production. Some users have reported to us that the newly installed paper cutter cuts one knife, and the edge of the knife is broken.
The choice of the blade sharpening angle of the paper cutter, the quality of the sharpening, and the blade sharpening gap time affect the flatness and smoothness of the cutting edge of the paper. The general blade angle is 19 °. If the cut paper is hard It is necessary to increase the angle of the blade. If you want to improve the quality of the blade, you must ensure that the coolant is sufficient to avoid the edge annealing. Before cutting, you can first sharpen the blade with whetstone, and on the blade Apply soap and paraffin, which can not only improve the sharpness and smoothness of the cutting edge, but also extend the service life of the cutting edge, and the quality of the finished product is better.
The reason why the cutter will collapse in actual operation is because the operator shortens the sharpening time and the coolant is insufficient, causing the edge of the blade to anneal and narrow the width. The nut must be adjusted during installation to make The blade is cut into the pad blade. If the nut is not adjusted well and the cut is too deep, it will cause chipping.
This is also a common problem with paper cutters. I hope you will pay attention when using paper cutters.
