Analysis and solution of non-heating reason of PP packing belt production line
Edit:Qingdao Mountain Plastic extruding Equipment Co., Ltd.   PublicDate:2017-11-20

In the process of using the PP packing belt production line, sometimes the machine cannot be heat-sealed well. What should I do if this problem occurs?

First analyze whether the following reasons exist:

First: Maybe you replaced the packing belt. The thickness of the packing belt was relatively thick, but now it is too thin. The hot head of the semi-automatic packing machine cannot be completely in place. Solution: re-adjust the position of the iron

Second: It may be that the position of the hot head of the semi-automatic baler is off or the joint of the strap is slightly off. Correct it.

Third: It has something to do with the material of the packing belt. Maybe there are more ingredients in the raw materials of your batch of packing belt. The main component of the packing belt used in the market is polypropylene, commonly known as pp. Better packing belts have a pp content of more than 95%. Other ingredients are more complex, such as calcium carbonate, talc, wollastonite, glass fiber and other inorganic fillers. If there are more ingredients, the hot melt viscosity will be worse. It is recommended that you ask the supplier to provide matching parameters.

Fourth: put it on the hot iron with a strap, check whether it will melt, check whether the hot iron can reach in, how long the machine has been used, etc.

If all the above problems are eliminated, then you can only judge the problem of PP packing belt production line or change parts.

The following are the problems existing in the PP strapping production line for your reference:

1. If the equipment does not heat up, we must first check whether the inside is vacuum. If it is vacuum, we must check the heating wire. If the heating wire is not hot, the heat sealing effect is not very good, then Controlled contact with the heater and problems.

2. We need to replace the heating wire in time so that the problem can be solved, or check whether the relay is intact. The relay is also used for heating. If it is not heated, it may also be a problem with the relay.

3. Method to check the production line of PP packing belt: If the packing belt machine just used has become thin, if the ironing head of the PP packing belt production line is not in the correct position, then we must adjust the position of the ironing head and place it. It can be adjusted accurately. If there is a problem with the quality of the PP packing belt, there may be a problem with the ingredients of the ingredients. If there are too many ingredients, the hot melt viscosity will be poor. We must carefully check when buying.

4. If there is no above problem, it may be that the PP packing belt production line has aged, or some parts need to be replaced, so pay attention to the maintenance of the PP packing belt machinery in the normal use process.
