How to offset the machine to extend the life of the equipment

In order to prolong the service life of the offset press and effectively improve the printing quality, the most important issue is to strengthen the maintenance and the maintenance of the offset press.

1. The production management system should include the following:

1 In order to reduce the wear and tear on the machine part, the required cleaning management and on-time lubrication lubrication offset printing equipment system are established.
2 Safety procedures for the prevention of damage to machine parts.

3 In order to eliminate the hidden dangers of machine accidents in a timely manner, and replace the naturally worn parts of the machine in time, the regular inspection and regular maintenance system is required.

2. The following points should be noted when refueling offset printing equipment:

1 Turn off the power while refueling the parts that need to be lubricated. Do not add fuel during start-up operation to prevent oil canisters from getting involved in the machine and causing machine or personal accidents.

2 Fill in the order of paper feeding, rules, water delivery, ink transfer, embossing, and delivery. Do not omit any holes that should be filled.

3 Do not add erroneous lubricants, avoid the use of oil as an oil, and accidentally hit the machine due to mistaken oil.

4 It should pay attention to the degree of oil cleanliness, the oil is not clean, there are impurities, it should be filtered to prevent iron scraps and dust in the oil from wearing out the parts and ensure the smoothness of the oil path of the oil pump.

3. Care and maintenance of offset printing equipment, operators and maintenance personnel must do the following:

1 The operator must have a deep understanding of the performance and structural principles of the offset printing equipment, be proficient and correctly adjusted, and ensure the proper operation of the machine. Offset of offset press should be promptly eliminated to avoid sick operation.

2 The environmental sanitation around offset printing workshop equipment should be kept clean and tidy, create a good working environment, and make all employees cultivate a good habit of civilized and healthy.

3 Timely dosing of lubricating oil, because the speed of offset printing equipment is at a high speed of 5000 sheets/hour, refueling has two roles: lubrication, and cooling. To ensure the smooth flow of oil. It is also necessary to conduct periodic inspections to inspect the wear of all major components and to avoid damage to the components due to sudden problems.

4 The offset printing shop shall formulate a set of rules for the implementation of equipment management. The equipment management shall be institutionalized and standardized, and the safety technical operation rules shall be strictly observed.

5 to strengthen the usual minor repairs, select the replacement of the parts of the material, make spare parts spare parts work, in order to shorten the maintenance time, improve equipment utilization, to ensure the integrity of offset printing equipment.

6 A technical file must be created for each offset printing device to record the wear of various maintenance components. Analyze the reasons, make corresponding conclusions, and accumulate experience from them.

7 Improve the ability to read drawings, understand the instruction manual of the offset printing equipment, the electrical schematic diagram of the offset printing equipment, master the use and maintenance of the electrical drive and the control part of the main engine, the principle of the electric drive, the engineering knowledge of the drawings, and only understand the drawings. Based on the above, the offset printing equipment can be repaired, and electric components must not be disassembled blindly.

4. In order to eliminate the hidden dangers of equipment accidents, each offset press is repaired once every six months, once in a year, and the overall inspection and analysis of the offset press is performed. The main inspection items and contents are as follows:

Check item:

1 The air pump of the paper feeding system sucks air and blows the air. The air pump is filled with vacuum oil in a timely manner. There must be no dirt fibers, dirt, etc. in the rubber tube wall of the gas transmission, so as to maintain the unobstructed gas path.

2 The grippers and their springs, the degree of fastening of the paper teeth and their springs, and the fixed adjusting screws of the plate, so as not to damage the rollers due to the escape of screws or plates.

3 The front gauge self-locking mechanism, the double-sheet controller, the safety bar on the paper feeding board, and the bearings on the ink roller prevent the rolling of the machine due to the balls falling into the gear after the bearing is broken.

4 Take-up chain pins and adjusting screws, bearings on the rollers and rollers of the water roller, ink roller, etc., components on the feeder, and components on the cardboard.

5. Check the content:

1 First, check the parts that are easy to loosen. Because the offset press runs at a high speed, the parts that are most likely to loosen and fall off are the adjustment and fixing screws of the grippers and paper feed teeth; the pins of the paper feeding machine for suction, and the delivery chain The pin and so on.

2 Check that the bearings that are worn on the bearings and parts are the most prominent ones. Severely worn parts are: roller bearings, gear bearings, balance cam bearings, and bearings on the ink roller. Worn bearings and gears must be replaced in time. Failure to do so may cause equipment failure.

3 Check whether the oil passages in the tubing, oil eye, and other locations are unobstructed.

4 Check the lifter of the paper feeder, such as the lifting and pulling of the suction iron, the pin of the delivery brace, and the shaft of the oil pump. These parts are likely to be broken due to the high possibility of breakage and should be promptly updated for all parts that are liable to break.
