Maintenance Strategy Selection of Baby Diaper Machinery

Introduction: with the continuous progress of science and technology and the rapid development of modern production, machines, as an important factor determining product production volume, quality and cost, are playing a more and more obvious role. In the process of use, the baby diaper machinery will inevitably produce varying degrees of wear, fatigue, deformation or damage. With the passage of time, the technical state of baby diaper machinery will gradually deteriorate and the use performance will also decline. As an important part of management, equipment maintenance is an important guarantee to prolong its service life, ensure the normal operation of production and prevent accidents. With the progress of production technology, enterprises have more and more types of equipment and stronger technicality. The failure rate curve is different for different. How to choose maintenance strategy for baby diaper machinery?

How to choose maintenance strategy for baby diaper machinery

Generally speaking, the larger the enterprise, the more equipment. There are many large and medium-sized enterprises. Different equipment plays different roles in the production and operation process of enterprises, and the maintenance methods are also different. When formulating the machine maintenance strategy, the importance of equipment should be classified first. There are many classification methods, among which ABC classification is a common and better method.

In a unit, the number of class a equipment is small and plays a great role, accounting for about 10% of the total. The configuration process is complex and is the key equipment in the production process of the enterprise. Once these equipment fails, it will cause significant economic losses and have a significant impact on the enterprise. Therefore, these machines need to have high reliability in the operation process. This should be the key object of maintenance work. For these key machines, appropriate repair methods should be selected from the economy of maintenance.

It is better to adopt the condition based maintenance mode for this kind of equipment, and change the planned maintenance to targeted maintenance. The implementation of condition based maintenance can greatly reduce the maintenance workload and maintenance cost, and achieve the effect of less input and more output. If there is no corresponding diagnosis configuration, or the cost of condition based maintenance method is too high, the technical and economic analysis results are inappropriate and the enterprise cannot afford it, standard maintenance method or regular maintenance method shall be adopted.

The fault information of baby diaper machinery determines the appropriate maintenance method

When repairing class B and class C equipment, appropriate repair methods shall be selected according to the equipment fault information. Fault information is the basis for determining the maintenance methods of these equipment. Through the analysis of fault information, the type of fault can be judged and the maintenance mode can be selected. Fault information mainly includes statistics on the number of equipment faults (shutdown frequency) and fault consequences (shutdown time, economic loss, etc.).

Collect statistical data on shutdown frequency (Times) and downtime of one year (or half a year, quarter and month). Plot downtime and frequency. Each unit has a large number of equipment. It is only necessary to list the equipment with the longest downtime and the most downtime, accounting for more than 80% of the total. It is planned to repair the equipment with long downtime and high frequency to completely eliminate the faults. For the equipment with low shutdown frequency but requiring a long shutdown time, the process and causes of fault shutdown shall be analyzed, and condition monitoring and condition repair shall be carried out. For equipment with high shutdown frequency and short shutdown time, the maintenance strategy is to improve the skill level of operators, which is generally completed by them. For machines with short downtime and low frequency, the way is not to break or repair.


The quality of the machine is the basis of safe production. Their operation quality requirements are very high, and the annual maintenance cost is also very high. Compared with the general mechanical maintenance strategy, it has both its commonness and particularity. The principles and viewpoints proposed in this paper need to be further deepened and refined according to the characteristics of the industry, so as to make a set of mechanical maintenance strategy suitable for baby diapers.
