The core equipment of printing enterprises is the puzzle books printing wholesale, which has a pivotal position in printing enterprises. Therefore, to ensure the good operation of puzzle books printing wholesale is the focus of production management of printing enterprises. Only the maintenance of puzzle books printing wholesale can ensure the smooth production of printing enterprises.

In the printing production process, everyone should care about the equipment, everyone should love the equipment, and have a high sense of responsibility and mission. When the author entered the factory, the master had taught us that "the factory is the face, the equipment is the eye", "the care of the equipment should be like the care of their own eyes", so that we can first establish the concept of caring for the equipment in our minds. In the production process, the operator should always pay attention to the state of the equipment, inspection Feida, printing unit, paper receiving part, air cabinet, water tank and compressor, etc. is abnormal, once found abnormal, should stop in time, find the cause at any time, eliminate the fault, the fault will be nipped in the bud. Our factory for Heidelberg printing press, the daily maintenance of equipment mainly has the following parts.

(1) Before turning on the machine every morning, the captain should check whether the CP window, LCD screen and console of the puzzle books printing wholesale are abnormal, and observe whether the moistening liquid and powder in the moistening liquid device and powder spraying device are used up to avoid dry pumping and dry spraying of the equipment.

(2) Check whether the baffle on the ink hopper is pressed tightly to avoid ink leakage during the printing process, resulting in the accumulation of ink on the side wall of the puzzle books printing wholesale.

(3) In the production process, the cuffs and hem of the operator's clothes should be fastened, the operator should wear soft-soled sneakers, do not allow to pile debris on the equipment pedal (such as cleaning agent, oil pot, car wash water and powder, etc.), and pull gently when opening the cover of the plate machine, do not allow to throw tools.

(4) Check the cleaning state of the stamping cylinder and plate cylinder. Before there is no production in the morning, the factory is often quiet, at this time you should run the equipment at a low speed, check whether there is abnormal sound, carefully listen to the gas path of each printing unit, and check whether the gas pipe has aging cracking and cylinder leakage. Many printing companies do not pay attention to the problem of air leakage, they often ignore the air leakage will not only accelerate the aging of the air pump, but also cause the production of water, ink road pressure is not in place, ultimately affecting the quality of the print.

(5) Daily maintenance is carried out in strict accordance with the Heidelberg operation manual every day, so as to be careful and meticulous, the refueling point and the cleaning point are meticulous, and do not ignore maintenance or perfunctory because of production.

(6) Before leaving work every day, the equipment should be comprehensively cleaned, cleaning the rubber roller, plate roller and impression cylinder of the ink road and waterway, removing the ink plate base of each printing unit, cleaning the shoulder iron and ink scraper. The author has seen a printing company's ink plate base used three days to remove and clean, but it is easy to cause the ink plate base to wear through, making the ink flow to the ink key motor, resulting in ink adjustment failure, and equipment difficult to operate normally.

Daily maintenance of equipment is the key to equipment maintenance, and printing companies should pay enough attention to it. In addition, in the daily maintenance of the equipment, printing companies should also pay attention to the minor faults of the equipment, deal with it in a timely manner, and do not muddle through. Some printing companies always blindly pursue benefits, and think that the operator is "grinding" to stop and maintain the equipment. Printing enterprise managers should abandon such a concept, on the contrary, the maintenance of equipment operators should be encouraged. Small problems in equipment are like small problems in the human body, and they should be handled by "medical treatment" in time, so as not to cause the consequences of "minor illnesses dragging serious diseases and serious tigers eating people".

Periodic maintenance is essential

I plant the equipment cycle maintenance is divided into monthly maintenance and quarterly maintenance. Periodic maintenance projects should be carried out in strict accordance with the Heidelberg operating manual. The team members of our factory have received strict training before boarding the machine, including the oil eye of the equipment, refueling point, maintenance details and maintenance content specified in the manual, and can only be on the job after passing the examination. Before each maintenance, the director of the printing shop should make the corresponding maintenance plan. Taking quarterly maintenance as an example, our factory's Heidelberg printing machine quarterly maintenance time is 2 to 3 days, in the maintenance, in addition to the requirements of the Heidelberg operation manual, we will also cooperate with the equipment department technicians to solve the fault in the usual work.

(1) First, use an industrial vacuum cleaner to vacuum the whole machine, clean the main and secondary water tanks, and replace the moistening liquid and filter cotton in the water tank.

(2) For the Feida part, replace all the Feida nozzle pieces, clean the lead screw, and add oil to the pull gauge seat; Check the Feida lifting track, chain, auxiliary lifting table track, and add butter to the track, gear, chain; Unscrew the air valve for dust removal, and install it properly after cleaning; Clean suction nozzle and paper transfer nozzle; Check whether the parting brush and the parting steel sheet need to be adjusted and replaced; Check the paper feed board air pipe, bottom gauge air pipe, adjust the valve, bond the paper feed cloth tape; Check whether the paper feed wheel and brush wheel need to be replaced; Check the electric eye and clean it carefully; Clean the pull gauge suction filter and replace it after 10 months of use.

(3) For the printing part, oil all the butter nozzles of the paper delivery roller, the impression roller, the paper transfer roller, the water bucket roller, the No. 3 ink roller (flat head roller), the ink bucket roller, the measuring roller, and the ink roller with the ink roller swing shaft under the ink bucket roller; Remove the inner wall adjusting screw, handle the baffle, bracket and accumulated ink; Clean the inner wall of each group of printing units, clean the bumper, clean the adjustment screws of each part of the plate clamp, so that it can move freely; Open the cover to check the solenoid valve of each cylinder; Clean the sink of each printing unit, scrape the deposited crystalline sediment, check the clean water level probe, upper and lower water pipes; Check the roller opening ball, rotate by hand, feel its flexibility, if the hair is astringent, it needs to be replaced; Check the surface of all rollers for crystallization and ink accumulation, use a micrometer to measure the size of both ends and the middle of the roller, if inconsistent, it will indicate that the roller has wear, need to be replaced in time; Check that all roller bearings need to be replaced.

(4) For the paper receiving part, clean the paper receiving teeth, paper receiving chain, gear, and add butter to all the butter nozzle; Check whether the oil level of the chain is normal; Clean the fans and check whether each fan needs to be replaced. Brush the receiving chain groove, guide die plate and track with butter; Check whether the speed reducer is damaged, use an industrial vacuum cleaner to clean the dust on the speed reducer guide plate, and wipe it clean.

(5) Stop and check the oil level of the whole machine, such as air compressor oil level and fan oil level; Clean the air filter; Open the air cabinet to check the motor, check the air duct and each group of air supply units; Check the water tank and dust the compressor radiator; Check whether all keys of the CP window console are flexible, if not flexible, they need to be replaced; Clean the machine waste oil and rotten paper under the machine.
