safety matters
General preventive measures
During the operation of the equipment, do not put items that are easy to slide or fall on the table, pedal or bracket.
It is generally forbidden to enter dangerous places or pay attention to signs, and do not touch the equipment unintentionally.
Put the tools back in place after use to prevent accidents caused by forgetting to put them back.
Don't put tools and articles in places that hinder your passage, such as passages.
Attention should be paid to setting off fireworks: smoking in designated places far away from equipment; Fire extinguishers should be set near the equipment for emergency use.
There are many rollers in the high-speed operation of the equipment. In order to prevent danger, attention should be paid to the clothing of operators: wear safety shoes; The coat should be stuffed into pants, and nothing should be put in the coat pocket; Don't wear gloves unless in special circumstances.
When the equipment is found to have abnormal sound or dangerous state, the equipment must be stopped immediately and the following items must be confirmed. After returning to normal state, make sure it is really safe before re-running.
When replacing defective parts, we should find out the reasons and try our best to prevent the accident from happening again.
Be sure to check the looseness of related parts, drive system and fastening bolts.
Use fretting to detect whether there is any foreign body rolling in and confirm whether it is safe.
Matters needing attention in equipment adjustment, maintenance and inspection
Parts related to equipment safety shall not be disassembled or replaced without reason.
After the operation, the bolts for installing the adjusting parts should be tightened and the fixing devices should be fixed.
When removing the safety cover and other components, be sure to restore the original state after completion.
Type of warning indication
In order to better understand the warning label of the equipment, inform the contents of the warning:
This language is used for safety precautions for parts in a more urgent and dangerous state. If this danger is not avoided, death or serious injury will occur.
This language is used in the safety precautions of potentially dangerous parts, which will cause death or serious injury if the danger is not avoided.
This language is used for safety precautions of potentially dangerous parts, such as minor injuries or moderate disabilities (if the danger is unavoidable), and matters that must be observed in order not to damage the equipment.
Overview of main components of equipment
Paper feed part
The cardboard piled up on the paper feeding table is automatically and continuously fed into the equipment without deviation. It consists of a paper feeding table, a front guide plate, a rear guide plate and a side baffle plate, a paper feeding roller that firmly grasps the cardboard from the paper feeding device and feeds the cardboard into the printing part, a paper kicking crank that makes the paper kick, and a paper feeding mechanism such as a gap device that smoothly sucks the cardboard through the front guide plate by using airflow.
Printing department
The printing part carries out specified printing on the cardboard according to the fact that the cardboard sent by the paper feeding part passes between the pressure roller and the printing plate roller with printing plates.
The printing part consists of a printing plate roller, a pressure roller, an anilox roller, an ink scraping roller, an ink supply and recovery device, an upper and lower paper feeding roller and a roller gap adjusting device.
Slotting machine department
The slotting part is a processing and forming process consisting of line pressing, slotting, trimming and pasting boxes.
The grooving part consists of a first line pressing, a second line pressing, a grooving machine, a corner cutter, a die cutter and a separating device thereof.
The rest
Folding and gluing machine part, reverse pushing part, console, operation panels of various parts, etc.
Equipment operation sequence
Operation preparation
Make sure that all switches are in manual or off state before inputting power.
Input power, first close the main power switch, and then close the sub-power switch, from big to small.
The air pressure should reach 6Mpa.
The water pressure should reach 2kg/cm2.
Prepare the required running materials, including ink, printing board, cardboard and others.
Running sequence
Install the printed board according to the contents of the production notice.
Calibrate the size of the paper feeder.
Calibrate the size of the feed table inside the print roller.
Adjust the size of the pressure groove.
Adjust the gap between ink rollers, so that ink can be transported smoothly.
According to the specifications of cardboard, adjust the gaps of each part (including paper feeding part, paper feeding roller, embossing roller, slotting and line pressing, etc.). )
Calibrate the dimensions of the stacker.
Such as Hamada printing slotted folding box bonder.

Problems existing in operation
Inclined feed
Original? Due to measures? carry out
The kick is not parallel to the front guide plate. The kick unit is not parallel to the front guide plate. Wear of ball spline shaft. Kick parallel adjusting bolt is loose. The front and rear guide plates are not parallel (the mounting bolts are loose). The height of the cardboard seat is not equal to the operating side and the driving side. The parallelism of the feed roller is poor. The upper feed roller is abnormally worn. The knurling apex of the lower feed roller is abnormally worn. The gap between the power supply side and the operation side of the front guide plate is inconsistent. The cardboard is in poor condition. The actual gap between the upper and lower feed rollers is inconsistent with the displayed gap. The surface rubber hardness of the upper feeding roller is improved. Correct to the appropriate state. ? After adjusting to the appropriate size, it is firmly fixed. After adjusting to the appropriate size, it is firmly fixed. Correct to the appropriate state. ? Correct to the appropriate state. Make a replacement. Make a replacement. Adjust to the proper clearance. ? Check the set size of the side guide and the size of the cardboard. Check that the side baffles are at right angles. Adjust the actual clearance to make it consistent with the displayed clearance. ? If the hardness exceeds 35 degrees, please replace it.
Wait a minute.
clean
Regularly clean the filter screen of the vacuum cleaner in the paper feeding department to remove the paper scraps and dust on the paper feeding baffle.
Take out the scraps of paper from the dust box.
When cleaning the anilox roller and the rubber roller, it is forbidden to wipe the surface of the rubber roller with cotton yarn, or brush the surface of the anilox roller with a brush and clean the roller with a cleaning agent. After cleaning, make sure there is no contact between the two rollers, otherwise the rollers will be damaged.
Clean the front side plate of the ink cover:
Remove the knob for installing the ink side cover, and pull the side cover forward to remove it.
Remove the upper recovery box and flush it with a hose.
Remove the knob for installing the recycling bin, pull up the recycling bin and remove it.
Remove the ink circulation hose at the lower part of the ink funnel.
Remove the knob for installing the Mo Dou, and pull the Mo Dou to the paper supply side to remove it.
The spilled ink sticks to it and becomes turbid, so it needs to be cleaned.
lubricate
For lubrication, please refer to the lubrication training materials and the lubrication nameplate on the machine.
The most demanding part in the load condition of printing machine is the kicking of paper in the paper feed part. Because kicking the ball moves back and forth, the ball spline is used at the kicking place, and the torque is great. Therefore, if we neglect to refuel this part, it will accelerate the wear of the shaft, sliding shaft, bearing and other parts, shorten the life of the machine and cause damage, so we must refuel every week. < sequence > lift the door in front of the door kicking device; Turn the coupling of the output shaft of the motor for kicking by hand, and move the kicking until the spherical spline can be supplied with oil with the lubricating oil gun; There is a lubricating oil gun to refuel the spherical spline shaft.
