Description

Technical Field

[0001] The utility model relates to the technical field of winding balers, in particular to a tension regulating device for a steel belt winding baler. Background Art

[0002] The steel strapping machine is a machine that uses steel strapping to wrap around products or packages, then presses the tightening button to tighten the excess steel strapping so that the steel strapping is close to the products or packages, and then connects the two sides of the steel strapping by melting it through thermal effects or using materials such as steel buckles. The main function of the steel strapping machine is to make the steel strapping close to the surface of the bundled products or packages to ensure that they do not fall apart during transportation and storage due to loose bundling. It also has the function of bundling products neatly and beautifully, avoiding messy placement and saving storage space.

[0003] Traditional balers cannot adjust the tension of the straps during packaging so that the packaging effect is not too loose or too tight to break, which causes considerable difficulties in transportation and handling. Existing balers mainly transport the straps by rotating the unwinding wheel driven by a motor. This transportation method makes it difficult to ensure that the unwinding speed of the unwinding wheel matches the winding speed of the winding mechanism, resulting in loose straps during the winding process.
