What is the reason for the weak sealing of the wet wipes packaging machine?
The wet wipes packaging machine is referred to as the wet wipes machine. The main reasons for the failure of this kind of sealing are as follows:
(1) The heat sealing temperature of the wet tissue packaging machine is not enough, as long as the heat sealing temperature is appropriately increased, the problem can be solved.

(2) The blade surface of the heat-sealing knife is not flat enough. The heat-sealing knife is divided into upper and lower parts. Usually, the thermoelectric coupling is installed in it to sense the transfer of temperature. There are three screws on the heat-sealing knife, and the middle screw is used to support and To strengthen the blade, the other two screws are equipped with pressure springs and gaskets, which are mainly used to adjust the pressure of the heat sealing knife. The upper and lower blades each have two springs. The main reason for the uneven blade surface of the heat sealing knife is the middle The screw is installed obliquely, not horizontally. Or the pressure spring of the heat sealing knife on the wet wipe machine is uneven. The solution is to re-calibrate the position of the middle screw to make it in a horizontal state. If the upper and lower heat sealing knives are unbalanced, adjust the pressure spring to achieve. Adjust it to a moderate level. When the spring is withdrawn outward, the heat sealing knife will fall downward. When the spring of the lower blade is tightened upward, the heat sealing knife will move upward.
(3) The uneven pressure of the cold-pressed rubber wheel of the wet wipes packaging machine will also cause this kind of poor sealing, and the solution is roughly the same as the first case.
Three-layer meaning: When the peeling test is performed on the sealing part, half of the sealing is firm and half is separated, and the sealing quality of such a packaging bag is still unqualified. Because the content is easy to leak through extrusion during storage and transportation, this situation often occurs when the composite lining is OPP and blow-molded PE.
There are two main reasons for the poor sealing failure of the wet wipes packaging machine
(1) The adjustment of the uneven pressure of the heat sealing knife or the uneven pressure of the cold pressing knife is exactly the same.
(2) The blade surface of the heat sealing knife is not flat enough. Refer to the corresponding solution for the second type of sealing failure.
2. The fuse of the wet wipes packaging machine is blown
The main function of the motor of the sealing machine is to drive the gearbox and the gear transmission of various components. Sometimes the sealing machine will make a "squeak" sound when it starts, and it cannot operate normally, and even the fuse on the live line is blown. To eliminate this fault, first check the power supply If it is normal, then cut off the power supply, use the resistance gear to test whether the switch is damaged, and carefully check whether the circuit and the motor are short-circuited. Usually, when the motor is short-circuited, the winding is burnt or the wire is broken, the fuse will blow as soon as the sealing machine is started. Another reason for this failure is that the fuse size is too small, and the problem can be solved by increasing its size accordingly.
The above is the solution to the tight sealing of the wet wipes machine.
