How to repair if the baler cannot be heat-sealed?

First check whether it can be evacuated, if it can be evacuated, then check whether the heating wire is heated, if the heating wire is not heated, see if the contactor controlling the heating wire is sucked, (or force the contactor to suck and see the heating wire Whether it is hot) Replace the heating wire without heating. Also check whether the heating time relay of the baler is intact and see what the setting time of the heating time relay is.

In addition, the following reasons are analyzed:

First: Maybe you changed the packing belt. The thickness of the original packing belt is relatively thick, but now it is thin. The ironing head of the semi-automatic packing machine cannot be fully in place. Solution: readjust the position of the scalding head

Second: It may be that the position of the scalding head of the semi-automatic packing machine is deviated or that the joint of the packing belt is a little deviated.

Third: It has something to do with the material of the packaging belt. You may have more ingredients in the batch of raw materials of the packaging belt. The main component of the packaging belt on the market is polypropylene, commonly known as pp. The pp content of a better packing belt should exceed 95%. Other ingredients are more complicated, such as calcium carbonate, talc, wollastonite, glass fiber and other inorganic fillers. If there are more ingredients, the hot melt viscosity is worse. It is recommended that you let the supplier provide the matching parameters.

If the above problems are eliminated, you can only judge the aging of the machine or replacement parts.
