Knowledge of management and maintenance of printing production equipment

<

As the saying goes: “Workers must sharpen their tools first if they want to do their best.” Equipment is one of the important hardware for printing production. It is an important factor that determines the production efficiency and product quality level. The most obtained in production and management practice Experience deeply. The production process practice shows that which factory equipment management and maintenance link is done well, its production efficiency and product quality are relatively high. In many years of work, I found that the same type of machines produced by the same manufacturer, due to the difference in operator's ideological quality and technical level, and the utilization rate and intact rate of the equipment also have obvious differences. Therefore, the high production efficiency and quality is not only a unilateral emphasis on machines that require advanced performance, but more importantly, it requires us to grasp the correct management and maintenance of equipment. This is very important, and modern enterprise management is worthy of attention and The subject of research.

Do a good job in the management of equipment procurement control

What equipment a modern enterprise uses for production largely determines the economic benefits and product quality of the factory. In recent years, China's printing production and related equipment have developed rapidly. There is also a certain gap between the technical capabilities and production scale of equipment manufacturers around the country. In this case, it is particularly important to purchase equipment correctly. Therefore, equipment procurement must be carried out step by step after the implementation of a series of management measures under the principle of "economic, applicable, efficient and high quality". After all, buying a machine is different from buying other commodities. If it is found that it is not suitable after sloppy purchase, it is too late. Therefore, when preparing to purchase a machine, you should first conduct a market inspection to fully understand and master the equipment market, initially determine its purchase intention, and then purchase after a series of reviews.

To avoid the "patriarchal" procurement method, some state-owned enterprises often purchase equipment based on the subjective will of the leading companies when they make technological transformations. As a result, they spent tens of thousands of yuan, or even one million yuan in equipment purchased, but few The month was eliminated because it was not used and became a pile of scrap iron. Because, after all, no matter how wise a person is, after all, it is just a person's wisdom. Therefore, in accordance with the ISO9001: 2000 standard to standardize equipment procurement management and control procedures, blindness in equipment procurement can be better avoided. Relatively speaking, when purchasing equipment, through the brainstorming of relevant personnel from various departments of the factory, participating in the review and determination of procurement, it is possible to more accurately purchase economic, applicable, efficient, and high-quality production equipment, which can better avoid purchase errors. Economic losses.

Prepared management, improve equipment production efficiency and product quality

Production equipment is expensive and practical, and management is important. No matter how good the performance and accuracy of the machine is, if there is no established management system or management measures are not implemented in place, the good-end machine may not be used for a long time, and it will wear out and damage there and become a broken machine, which cannot play a role. It is undeniable that in reality, some employees may inevitably pursue the output in a one-sided manner, ignoring the correct use and maintenance of the machine, or starting the production at overspeed or not refueling as required, and inspecting and handling the minor problems that exist in the machine without stopping, but reluctant Let the machine run production with disease, which is caused by the vacuum in equipment management. Therefore, to avoid and eliminate such undesirable conditions, the factory must establish a sound equipment management system and implement a series of strict management measures. The main practices are:

1. Select the right staff to operate the machine with advanced performance. After purchasing a new machine with high technical content, you must choose employees with good ideological quality, more sensitive mind and certain production experience to operate. This is related to the production efficiency and intact rate of the machine, whether it can be properly played and improved. The problem is an important link that should be considered in equipment management and production management.

2. Provide the necessary training to the operator of the machine. Necessary technical training should be carried out for the employees who operate on the machine, so that the employees understand and master the performance of the machine, be familiar with the technical requirements, operation essentials and adjustment methods of the equipment manual, regulate the operation of the equipment, prevent and reduce Abnormally damage the equipment.

3. Check and assess the use of equipment. In daily production, it is necessary to pay attention to the necessary inspection and assessment of the use and maintenance of equipment, and to incorporate it into the track linked to the economy, give appropriate rewards for the good use of equipment, and do the work of equipment use and maintenance In the case of bad, abnormal damage, it should be given economic punishment in order to play an effective restrictive role.

4. Analyze the causes of equipment accidents. Equipment accidents are common in production. There are two reasons for equipment accidents, one is a normal accident and the other is an abnormal accident. However, no matter what kind of accident, it is necessary to carry out cause analysis and find out the source of the accident in order to take measures to correct and prevent it. Generally normal accidents are mainly caused by long-term use of equipment and aging, wear and fatigue of various components. Unusual accidents are caused by operator's human factors, such as errors in machine adjustment, careless operation, long-term lubrication of the machine's lubricated parts or foreign objects caught in the machine. Therefore, only when the cause of the accident of the equipment is identified, corresponding measures can be taken to awaken to correct and prevent.

5. Determination of equipment repair level. Partial minor repairs to the equipment are simple repairs and repairs to a certain part; replacing parts with faster wear and tear, and adjusting the local mechanism of the equipment to ensure the normal operation of the equipment until the next scheduled repair time. The intermediate repair of the equipment is to partially disassemble, repair or replace some main parts of the equipment, so that the technical performance of the equipment after the intermediate repair is basically the same as the overhaul. Equipment overhaul requires disassembling most of the equipment and replacing or repairing all major components that are aging, damaged, worn, rusted, corroded and have lost their normal working performance (including car, planer, plating and other processes), so that The equipment after the overhaul basically resumes the performance required for production. Maintenance of production equipment is an important measure to improve production efficiency and product quality. Therefore, we must pay attention to lubricating, cleaning, adjusting or replacing worn parts on some parts of the equipment. This is an important measure to prevent equipment accidents. Preventive maintenance must be carried out on some parts of the equipment that are prone to failure. According to the requirements of the equipment manual, some parts of the machine should be regularly overhauled, such as worn gears, corrugated rollers, bearings, bearing bushes and other vital parts.

6. Establish equipment files. It is very necessary to establish equipment files. The original technical data of the equipment, instruction manuals, circuit diagrams, etc. must be kept by a dedicated person, and the machine can only use copies. Failures and repair schemes during the use of the equipment; the characteristics, causes and hidden dangers of the failures are all recorded in the equipment file in detail, so as to facilitate future repairs and preventive work.

Do the third-level maintenance of equipment

The maintenance of equipment in general factories is divided into three levels. The author believes that first-level maintenance is the content of daily maintenance. The operator is required to carefully check the operation of the equipment in strict accordance with the operation rules of the equipment, wipe each exposed part, and add each lubrication part. Corresponding lubricating oil keeps the equipment always clean, good lubricating state and safety performance. For equipment failures in the middle of production, they should be eliminated in time to prevent them from producing disease, and the handover of equipment operation status should be done carefully. The second-level maintenance is based on the principle that the operator is the main, and the repairman is the auxiliary. The equipment is partially disassembled, inspected and cleaned according to the plan. The work includes dredging the oil roads, pipelines and tracks, replacing or cleaning the curves, linoleum and oil filters Readjust the fit clearance of some parts of the equipment, check whether there are loose parts on the fastening parts of the equipment, check whether the moving parts are worn, check whether the mechanical parts are damaged, fill in the equipment maintenance records after the second level maintenance is completed, and pass Acceptance confirmation by relevant technical management personnel. The three-level maintenance of the equipment is mainly based on the maintenance workers. According to the equipment maintenance plan, the equipment is inspected and repaired on a large area or partly disassembled, and the worn parts are replaced or other repair measures are taken. "The parts are cleaned and oil changed. At the same time check and repair electrical parts to ensure that they maintain reliability. After the third-level maintenance is completed, the third-level maintenance record should also be filled in. After being inspected and accepted by the workshop director and technicians in conjunction with the equipment management personnel, the on-site inspection and test run operation will be integrated.

Proper use of equipment, improve equipment production efficiency and improve

In the daily production process, the wear and damage of some equipment are caused by improper use and maintenance, such as the operator is unfamiliar with its performance and use methods, blind operation, blind adjustment, poor lubrication, ultra-high-speed startup operation, etc. As long as the machine's lubrication work is done well and the machine is driven at an appropriate speed, its service life is long and its accuracy is high. The use of the machine should also pay attention to methods, such as circular flattening and circular pressure round structure printing machines, and must not perform high-speed jogging and operation under the pressure-off state to prevent wear or damage of the gear. The single-sided machine should run empty for a period of time before shutting down. After the temperature of the corrugated roller is cooled, it can be completely shut down to prevent the machine from standing still for a long time at a time to easily deform the hollow corrugated roller.

"Three Good" and "Four Meetings"

Implement a three-level maintenance system for equipment, requiring operators to achieve "three good" and "four meetings"

1. "Three good" requirements for equipment. The "three good" of the equipment first requires the equipment operator to manage the production tools, accessories, accessories, etc., the machine lines and pipelines are intact, the production tools are neatly placed, and the safety protection devices are complete and easy to use. It is necessary to abide by the equipment management system of fixed personnel and fixed machines. Special positions can only start production based on the equipment operation certificate, and do not open other people's machines indiscriminately; Run the production with disease, do not allow the equipment to be overloaded, try not to allow the equipment to be "large and small" or "precise and coarse", follow the equipment operation regulations and maintenance regulations, just like caring for your bicycle or motorcycle, Take care of the production equipment of the factory to prevent man-made damage to the equipment; third, to repair the production equipment, according to the scheduled maintenance time, the shutdown must be shut down for maintenance on time, and the operator must actively cooperate with the equipment maintenance worker to do the equipment maintenance And maintenance work.

2. The "four meetings" requirement of the equipment. The "four meetings" of the equipment is to require the equipment to use the machine. First of all, you must be familiar with the equipment structure, performance and operation methods, familiar with the production process regulations, and be able to correctly operate the equipment. Secondly, the operator is required to maintain the machine, be familiar with the content of the first-level maintenance, refuel, change the oil, keep the oil line open, keep the oil line, linoleum, and oil filter clean, and keep the inside and outside of the equipment. For cleaning, there should be no obvious grease or other dirt on the machine parts. Third, the operator is required to check the machine, be able to understand the technical specifications and performance of the device, check the device safety protection and safety device; check the production quality problems caused by the device, and make appropriate adjustments to the device or propose a device maintenance plan . Fourth, the operator is required to eliminate the fault. The fault location and cause of the equipment are determined by the sound of the machine, the temperature of the parts and the working status of the moving parts of the machine, and correct measures can be taken to eliminate the fault in time.

In summary, the use and maintenance of printing production equipment is a very deep knowledge. It is necessary to continuously sum up experience in practice and constantly improve management measures to gradually form a more scientific and reasonable management method and system, so that various The production equipment gives full play to its role in improving the production efficiency and quality of the factory.

Lip Mud

The texture of the lip mud is relatively dry compared to the Lip glaze, which can protect the lips for a long time, while correcting the contour of the lips and making the lips look better.

Features of lip mud:

1. Matte + plush

2. Matte + durable and easy to remove

3. Strong coverage

4. Literally, wet mud-like, lumpy but easy to wipe off. Blush can be made if the color is right (because it is so faint)

Compared with matte lipsticks, the lip mud has a much higher level of delicacy, and because of the use of a Lip Brush to apply makeup, the fineness is also greatly improved.

Compared with matte lip glaze, the matte effect is more extreme; and compared with matte makeup Lipstick, it has better extension. therefore

The biggest selling point of lip mud is its delicate balance between matte and delicate feeling, which is most suitable for European and American makeup lovers. After all, most matte lipsticks are difficult to control, but matte lip glaze is not so "pure". However, it is precisely because of the matte "gene" of the lip mud that there are still some "minefields" in use that require attention.
