During the long-term use of the electronic shaft printing machine, the wear of the mechanical parts, the increase of the gap, and the change of the degree of coordination will directly affect the original balance, stability and reliability of the equipment, reduce the use efficiency, and even cause the machine to malfunction. operation. Therefore, the overhaul or replacement of equipment will undoubtedly increase the cost of the enterprise and affect the rational allocation of enterprise resources. So, let's take a look at the maintenance of the electronic axis printing machine.
The maintenance of the electronic axis printing machine is mainly to maintain the printing performance of the equipment and maintain the key parts of the equipment. Therefore, printing enterprises need to establish a scientific and effective machinery and equipment management mechanism, increase the daily management of equipment. Maintenance is not only cleaning and lubrication, but also includes finding hidden dangers while cleaning, eliminating them in time, and maintaining the performance of the printing press.
Key maintenance of important parts of electronic axis printing machine:
The structure of the electronic axis printing machine is more complex, the parts are many, and the processing accuracy is high. In order to make the machine play its role in good condition, the maintenance department of the enterprise must focus on the maintenance of its important parts, such as rollers, transmission gears, handover devices, paper feeding parts, bearings and electrical appliances.
The blanket cylinder, impression cylinder and plate cylinder are the main body of the printing press and are the important parts that determine the printing quality. During use, the operator must be careful to prevent paper and various foreign objects from rolling into the roller, such as screws, washers, springs, bearings, tools, etc.
The manufacturing accuracy, installation accuracy and adjustment of the roller drive gear are closely related to the printing quality. Therefore, the operator should prevent dust, garbage, paper and hard objects from rolling in to avoid damage to the gear. Electronic shaft printing machine generally adopts oil injection lubrication. The operator should always check whether the oil passage is unblocked, keep the tooth surface clean, and reduce gear wear.
The transfer device is a part of the transfer paper that ensures accurate overprinting. The operator should always check the pins and adjusting screws of the paper feed chain to prevent loosening and breaking to avoid accidents.
After the parts on the paper feeding device are loose and damaged, it will not only affect the paper feeding accuracy and increase the rejection rate, but also cause major accidents due to the loose and damaged parts entering the roller with the paper. Therefore, these parts must be checked regularly. If they are damaged, they must be replaced immediately. If the screws are found to be loose, they must be tightened immediately.
In order to meet the needs of high-speed operation of electronic shaft printing machines, bearings are often soaked in ink and liquid medicine, which is not easy to clean and lubricate. If the maintenance is not good, it is easy to drop the broken ball and crush the machine. Therefore, maintenance personnel need to apply new butter to the bearings every week to ensure good lubrication.
In terms of electricity, the electrical switch box should be cleaned regularly by designated personnel and responsible persons to prevent accidents caused by the heating of electronic components of the circuit board.
electronic axis printing machine level maintenance:
If a worker wants to do a good job, he must first sharpen his tools. The purpose of equipment management is to improve the utilization rate of equipment and prolong the service life through maintenance, so as to seek economic benefits. To this end, the company has adopted a "maintenance system". Level 1 maintenance refers to routine maintenance that requires the operator to carefully inspect the printing press during each shift. In addition to refueling the relevant parts according to regulations, it is also necessary to observe the movement of the parts at any time during the production process.
electronic axis printing machine secondary maintenance:
Regular maintenance once a week, usually on Thursdays, allows 4 hours of downtime. Some operators will carry out local disassembly and inspection of the equipment, clean the specified parts, check the oil volume of the oil circuit, check and adjust the important parts, check whether the connection is loose, and correct it if it is loose.
electronic axis printing machine maintenance:
Twice a year. Mainly by professionals, operators cooperate with each other for maintenance. It is necessary to disassemble and inspect the key parts such as the paper separation nozzle, paper feeding tooth row, paper feeding tooth row, chain roller tooth row, etc., and at the same time clean the lubrication system, refuel, and check and repair the reliability and insulation of the electrical system.
