Does The Wear And Tear Of The Packaging Machine Have A Big Impact?

Wear and tear of packaging machine equipment

The physical wear during the use of the equipment includes both normal wear and abnormal wear caused by storage, improper use and corrosion by natural forces (caused by harsh working conditions). The result of wear and tear of the packaging machine, usually manifested as:

(1) Change the original size of the parts and components that make up the equipment. When worn to a certain extent, it will even change the geometry of parts and components.

(2) Change the nature of the mutual cooperation between parts and components, resulting in loose transmission and reduced accuracy and performance.

(3) Damage to parts, or even damage to other parts associated with it due to damage to individual parts, resulting in damage to the entire component, resulting in serious accidents.

Wear stages of packaging machine equipment

Under normal circumstances, during the use of equipment, the wear of parts and components has certain rules, which can be roughly divided into three stages:

The first stage: the initial wear stage (also called the run-in wear stage). At this stage, the macro-geometry and micro-geometry (roughness) of each part and component surface of the equipment have to undergo significant changes. The reason for this phenomenon is that in the process of machining and manufacturing, no matter what kind of precision machining, the surface of the parts still has a certain roughness. When mating with each other for relative motion, such as rough surfaces wear due to friction. The wear rate at this time is very fast, and the amount and time of wear depend on the roughness of the parts. This phenomenon generally occurs in the general assembly and commissioning of equipment manufacturing and repair, and the commissioning and initial use stages during the commissioning and initial use period.

The second stage: After the surface of the relative moving parts and components is worn in and worn, the wear enters the second stage, that is, the normal wear stage. During this stage, if the working conditions of the parts remain unchanged or change very little, the wear amount increases at a constant rate with time. That is to say, under normal circumstances, parts and components wear very slowly. When the wear reaches a certain level and the part cannot continue to work, the time at this stage is the service life of the part.

The third stage: severe wear stage. The appearance of this stage is often due to the fact that the parts have reached their lifespan and continue to be used, which destroys the normal wear relationship, aggravates the wear, and sharply increases the amount of wear, resulting in a significant decline in the accuracy, technical performance and production efficiency of machinery and equipment. For example, the mutual friction between the shaft and the sliding bearing on the machine equipment, under normal circumstances, is separated by the fluid or semi-fluid in the mutual fitting gap, so that they do not directly contact friction. When the shaft or bearing is worn to a certain extent and continues to be used, the amount of oil or grease will be insufficient due to the increased clearance, and the liquid friction will lose its effect, causing direct friction between the shaft and the bearing, and the wear will be aggravated.

Knowing this law, we can make the initial wear stage as short as possible, the normal wear stage as long as possible, and avoid severe wear stage. The initial wear stage is short, indicating that the parts and components of the equipment are of good quality.
