Problems solved by technology

Its shortcomings: First, when splicing plastic sheets, since the non-ferrous metal strip electrode plate is not elastic, the precision of its mechanical manufacturing cannot guarantee the contact between the high-frequency electrode plate surface and the non-ferrous metal strip electrode plate on the work table. The gap is constant. Since the high-frequency electrodes are in a short distance, the hot-melt surface is inconsistent, and there are disadvantages of partial fusion bonding and partial non-bonding. Even if the wheel surface of the setting wheel is pressed on it, the unheated The melted material is fused together, so it is inevitable to produce a small amount of splicing leakage at the splicing place, and the splicing leakage is extremely difficult to be found. Generally, people can't detect it by visual inspection; secondly, although the leakage is not Occurs frequently, but once it occurs, the leak will lead to water seepage, air leakage, etc., which will seriously affect the service life and use effect of the product, especially for long and super long splicing products, the material of the splicing place The complete fusion is particularly important, otherwise the spliced ​​products will be scrapped, especially for large and super-large color advertising light box fabrics, membrane structure houses, roof tarpaulins, container tarpaulins, membrane structure swimming pools, water beds, wind tunnels , agricultural film, salt film, and film toys, the loss is not only the splicing product itself, but the economic effect of the entire product
