AI Technical Summary
When existing strapping machines are used continuously for a long time, the concentricity of the motor stator and rotor of the wire feeding mechanism decreases due to thermal deformation, which affects the reliability of wire output and the quality of strapping.
A metal bracket is installed inside the casing of the strapping machine. The stator of the wire feeding motor is connected to the metal bracket, with the stator exposed from the open part. The rotor of the wire feeding motor is connected to the metal bracket through bearings, ensuring that the stator and rotor are on the same axis, thereby enhancing heat dissipation and connection stability.
Even if the casing deforms due to heat, the concentricity of the stator and rotor of the wire feeding motor remains unchanged, ensuring smooth wire output during long-term operation of the strapping machine, thus improving wire output reliability and strapping quality.

It is operated by workers and used to bundle and fix steel bars with iron wire to ensure the stability and safety of the structure. This equipment plays an indispensable role in modern construction, and its convenience of operation and reliability of bundling directly affect the quality and efficiency of the project.
[0003] The existing bundling machine is usually composed of multiple functional units, which cooperatively complete multiple steps such as feeding, guiding, curling, holding, cutting, twisting, and releasing of wire.
