Description

Technical Field

[0001] The utility model relates to the technical field of heating furnaces, in particular to a heating furnace for a continuous strapping production line. Background Art

[0002] Metal strapping is primarily used in situations where extreme strength is required, such as transporting bulk goods. They are typically made of steel and coated to prevent rust and corrosion, making them particularly suitable for use in a variety of industries, including logistics, construction, and furniture manufacturing.

[0003] Heating is a crucial step in the production of metal strapping, directly impacting the quality and performance of the product. The purpose of heating is to alter the physical and chemical properties of the metal to meet the specific strength, toughness, and durability requirements of the strapping.

[0004] The choice of heating method is crucial for ensuring product quality, improving production efficiency, and reducing production costs. Existing technology generally uses a heating furnace for induction heating of strapping tape, heating the metal through the thermal effect generated by the induced current. Induction heating devices are suitable for localized or overall heating of various metal materials. They offer advantages such as fast heating speed, easy temperature control, and minimal oxidation and decarburization, making them widely used in the production of metal strapping tape.

[0005] During the heating process of the strapping tape, it is necessary to ensure that the strapping tape passes through the heating port of the heating furnace at a uniform speed. In the prior art, two support frames are mostly fixed by bolts at the heating port of the heating furnace, and then a feed roller is rotatably arranged in the support frame. The strapping tape is clamped by the two feed rollers, and then the strapping tape is fed by the rotation of the feed roller. However, in the actual production process, the thickness of strapping tape of different models is different, which requires continuous position adjustment of the support frame. At the same time, since the support frame is fixed by bolts, it is necessary to rotate multiple bolts in sequence, which is time-consuming and labor-intensive and affects the heating efficiency of the strapping tape.
