<p>At present, many companies will choose the <a href="https://www.ntjl.com/strapping-machine" rel="noopener noreferrer" target="_blank">strapping machine</a> to carry out the auxiliary work of packing, but many people find that the machine cannot be heated after a period of time or a long time. Do you know the reasons? Let's let the editor of SCGC explain it to you.</p><p><br></p><p>1. Check whether it can be vacuumed, if it can be vacuumed, then check whether the heating wire is heated, if the heating wire is not heated, check whether the contactor that controls the heating wire is sucked, (or force the contactor to suck and check heating (Whether the wire is hot) Replace the heating wire without heating. Also check whether the heating time relay of the strapping machine is intact and see what the set time of the heating time relay is.</p><p><br></p><p>2. It may be that the packing belt has been replaced recently. The original packing belt was thicker, but the current one is too thin, and the ironing head of the semi-automatic packing machine cannot be fully in place. Solution: readjust the position of the ironing head.</p><p><br></p><p>3. It may be that the position of the ironing head of the semi-automatic packing machine is off or the joint of the packing belt is a little off. At this time, only need to correct it.</p><p><br></p><p>4. It has something to do with the material of the strap. Maybe your batch of strap raw materials contains more ingredients. Now the main component of the strap on the market is polypropylene, commonly known as pp. The pp content of a better packing tape should exceed 95%. Other components are more complicated, such as blending inorganic fillers such as calcium carbonate, talc, wollastonite, and glass fiber. If there are more ingredients, the hot melt viscosity will be poor. It is recommended that the supplier provide the ratio parameters when using the machine.</p><p><br></p><p>5. If none of the above problems are found, then it is possible that the machine is aging or the accessories are damaged. At this time, the machine or accessories can only be replaced.</p><p><br></p><p>The above are the 5 major reasons why the packer cannot be heat-sealed. I hope it will help everyone.</p>
