How to solve the lax sealing of the film sealing machine? Four aspects to directly attack the “lax” problem?
As the weather gets colder, it is very pleasant to hold a cup of hot milk tea and soy milk. With the emergence of milk tea and soy milk machines, it not only improves the production efficiency of beverages, frees hands, but also makes product production safer and more hygienic. In particular, after being sealed by a professional sealing machine, milk tea and soy milk can not only prevent contamination by external bacteria, microorganisms, etc., and will not change their taste, but also do not have to worry about the risk of spilling drinks, which is easy to carry.
At present, milk tea, soy milk and other beverages purchased in stores usually need to be sealed. On the one hand, after strict sealing, the air “outside the cup” is isolated, which can effectively prevent the beverages from being polluted, and will not become stale or spoiled or rotten. Therefore, the purpose of prolonging the shelf life is achieved, and on the other hand, it is beneficial to avoid spillage and spillage of beverages, and is convenient for consumers to carry. However, users often complain that the sealing is unstable, or consumers report that milk tea and soy milk are not tightly sealed, resulting in spillage and other problems.
It is understood that automatic sealing machines mainly include three categories, such as plastic film sealing machines, aluminum foil sealing machines, and ink wheel sealing machines. Among them, plastic film sealing machine is divided into film continuous sealing machine, plastic film sealing machine, vertical film sealing machine, which are mostly used in the sealing of milk tea, soy milk and other beverages, that is, by directly heating and applying mechanical pressure at the sealing place, And perform automatic heat sealing to fuse the seal, make the edge of the cup and the film bond, and then automatically trim the edge to achieve the purpose of sealing.
According to users, “Compared with traditional manual sealing, the plastic film sealing machine has a high degree of automation, fast sealing speed, high efficiency, and good sealing effect.” So, why does the plastic film sealing machine still have the problem of poor sealing during the sealing operation?
According to the analysis of professional and technical personnel, there are four main reasons for the poor sealing of the plastic film sealing machine, including:
First, the heat sealing temperature, pressure and speed are not suitable. “When the plastic film sealing machine heat-seals different film materials and thicknesses, the heat-sealing temperature and pressure are different,” said a manufacturer. The author understands that as the total thickness of the film increases, the heat sealing temperature must be increased accordingly, and the pressure must be moderate, so that the clamping spring does not need to be adjusted. In addition, the heat sealing speed should not be too fast or too slow. Otherwise, the rim and film will not be able to bond and seal before they have time to heat up.
Second, the cutting blade has residue attached. Due to the long-term use of the plastic film sealing machine, the carbonization of residues cannot be avoided after the film is high temperature, which will affect the sealing quality of subsequent beverages such as milk tea and soy milk. Therefore, users should regularly maintain and clean the cutting blade of the plastic film sealing machine.
However, users should not use brute force when cleaning, but try to use warm water to soak the residue and get it off the blade first, which can not only achieve a deeper cleaning, but also avoid damaging the cutting blade with improper force.
Third, the quality of the heat-sealing film packaging is poor. The quality of the heat-sealing film packaging also directly affects the sealing effect of beverages such as milk tea and soy milk. Because the material of the heat-sealing film is poor, the original heat-sealing temperature, pressure and speed will not be able to achieve the heat-sealing effect well, and at the same time, the film material will be wasted.
Finally, if the heat-sealing film packaging material or the seal has dirt, such as moisture, dust, oil, etc., the heat-sealing film will not be able to adhere to the edge of the cup, thus affecting the sealing quality of beverages such as milk tea and soy milk.
Today, milk tea, soy milk and other beverages have been automatically sealed by film sealing machines, which greatly improves the sealing efficiency. However, users must ensure the quality of sealing during equipment operation to avoid problems such as loose sealing of beverages, so as to better facilitate consumers. , and ensure product drinking safety.
