What are the common faults of wet tissue packaging machine

Time:2021-09-16 10:37 Author:Suny Group

The wet tissue packaging machine has been used for a long time, especially under continuous operation and overload conditions, it is prone to some electrical and mechanical failures, such as: weak seal, machine stop and go, fuse blown when starting, and issued during operation" "Squeaking sound", uncontrollable temperature, deformation and bending of the finished bag at the sealing point, bubbles or irregular marks at the embossing point of the sealing knife, etc.

Portable Wet Wipes Making Machine

Combining the actual use experience of the wet tissue packaging machine, for several of the failures, the causes are analyzed, the corresponding solutions are proposed, and the maintenance problems of the continuous sealing machine are explained, hoping to help enterprises and individuals who use the continuous sealing machine.

1. The wet tissue packaging machine is not well sealed, which is one of the common failures of the continuous sealing machine. There are three meanings for the weak sealing:

The first layer means: the sealing part of the packaging bag cannot be sealed;

The main reasons for this kind of failure are as follows.

(1) The heat sealing temperature of the wet tissue machine is not enough

Under normal circumstances, when the total thickness of the composite bag with OPP as the lining is 80~90μm, the heat sealing temperature should reach 170~180℃; the total thickness of the composite bag with PE as the lining is 85~100μm At this time, the temperature should be controlled at 180~200℃. As long as the total thickness of the bag is increased, the heat sealing temperature must be increased accordingly.

(2) The heat sealing speed is too fast

The inability to seal is also related to the speed of the sealing machine. If the speed is too fast, the sealing part will be transported to the cold pressing part for cooling treatment before it can be heated in the future. Naturally, the heat sealing quality requirement will not be met.

(3) The pressure of the cold-pressed rubber wheel of the wet tissue machine is not suitable

There is one upper and lower cold-pressed rubber wheel, the pressure between them should be moderate, and only the spring needs to be clamped when adjusting the pressure.

(4) There is a problem with the quality of the heat-sealing film of the wet tissue packaging machine

The inability to seal the seal is also related to the quality of the heat-sealed film. If the corona treatment of the composite lining is uneven, the effect is not good, and it happens to be at the seal, it will definitely not be able to seal. This situation is rare, but once it occurs, the product must be scrapped. Therefore, in the color printing and packaging industry, the next process is to supervise the previous process. Once a quality problem is discovered, the cause must be analyzed and resolved in time. If there is moisture and dirt in the seal, it will also cause the seal to be weak. In short, to solve the first problem of weak sealing, generally increase the heat sealing temperature appropriately, then reduce the heat sealing speed, and increase the pressure of the cold-pressed rubber wheel at the same time.
