What Problems Will Be Encountered During the Production of Masks?
What Problems Will Be Encountered During the Production of Masks?


There are many factors influencing the stability of the face mask machine. One is the problem of the face mask machine itself, and the other is the problem of raw materials, which is also a major factor affecting production.


1. The fabric used in the face mask machine:


In terms of fabrics, the width and thickness of meltblown fabrics and non-woven fabrics will directly affect the normal use of the face mask machine. For example, in the actual production process, if the fabric is wider, it may exceed the machine's shaping range during the shaping process, and many problems will be encountered in the process of wrapping the ridge of the nose. In extreme cases, the defect rate caused by the reason exceeds 50%, and a lot of time, energy and materials are lost in the process of debugging, which is very terrible.


If the plastic tape is not properly shaped, it may cause the mask to be unsmoothly folded, the nose clip line folds to accumulate wrinkles, the pressure welding formed by the body  not to be good enough, or the welding action of the edge banding not to be completed, which are the common phenomena in the production of masks. Among all the bad factors, the bad rate due to shaping problems accounts for 40% to 60%.


2. The ridge of the nose used in the face mask machine:


The width, thickness, and flexibility of the ridge of the nose, whether it contains iron wire, whether it is one iron wire or two iron wires, have different effects on different face mask machines. For example, iron wire will definitely have a great influence on the wear of the knife.


The ridge of the nose is the second largest contributor to the defect rate. The problem with the ridge of the nose may be due to two reasons: One is that as mentioned before, the shaping is not good and the wrapping is not smooth; The other is that the cutting of the ridge of the nose will break the knife edge. And it will also cause a lot of other problems. For example, it cannot be cut off, or the angle of the cut is not good, resulting in accumulation or dislocation of the ridge of the nose. Because our masks require that the ridge of the nose must be centered, if the position is off, the mask is theoretically unqualified. At least when it is worn, it will cause some trouble to us.


3. Ear straps used in the face mask machine:


The elasticity, thickness, and cylinder or flat shape of the ear straps all greatly interfere with the pass rate in the actual production process.


For experienced automation engineers, it is not difficult to adjust the strapping (earband welding) machine. You can see it at a glance, and you can know the actual structure of the action. However, in actual production, there have been various minor problems such as failure to pull the wire, cutting the wire, weak welding, deflective welding, full penetration, and unqualified tensile test. A large number of defective products are produced, and many links need to be debugged and require maintenance.


The design of the face mask machine itself is the biggest factor affecting the stability and yield of the earband welding. Regardless of whether it is a linear drawstring type, a reciprocating drawstring type, or a rotary drawstring type, each has its own corresponding characteristics. You may think that the rotary type is a bit more stable, but in terms of efficiency, the drawstring type is higher. We must deploy manpower and material resources according to the purchased equipment and the characteristics of the actual operation.
