Continuous high-frequency welding machine and welding method

Abstract

The present invention is developed on the basis of available continuous HF fusion welding machine and fusion welding method and has improved long non-ferrous metal electrode plate. Structurally, the present invention has flexible material inside the longitudinally open-mouthed section, conducting copper sheet on the flexible material and insulating layer on the conducting copper sheet; as well as wheel protecting belt below the movable HF electrode plate heat jointing and settling assembly. The present invention has the advantages of the complete fusion and adhering of the jointed material, no adhesion between the HF electrode plate heat jointing and settling assembly and the jointed material and high welding quality.

Description

Technical field: [0001] The invention relates to a high-frequency continuous welding equipment for fusion bonding of polymer membrane materials, which is mainly used to produce large and super-large color advertising light box cloth, membrane structure houses, roof tarpaulins, container tarpaulins, and membrane structures Swimming pools, water beds, wind tunnels, agricultural films, salt films, and film toys belong to the B29C65 / 00 manufacturing field. Background technique: [0002] The applicant’s all publication number CN1387992A, the name "continuous high-frequency plastic heat sealing machine", the unit is located on the guide rail, one end of the cantilever beam is connected with the automatic control power track unit, the other end is equipped with a cylinder, and the surface of the workbench or the workbench is neutralized The sides are respectively provided with a non-ferrous metal strip electrode plate and a non-ferrous metal strip plate parallel to each other. The non-f...

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
