[0002] Aluminum alloy pipe strip refers to the original material used to produce aluminum alloy pipes. It usually exists in the form of strip or coil. High-frequency welding uses the skin effect and proximity effect of high-frequency current to highly concentrate the current on the edge of the steel strip to be welded, thereby quickly heating and reaching the welding temperature. The strip introduction device needs to be closely coordinated with the high-frequency welding unit. The high-frequency welding aluminum alloy pipe strip introduction device is mainly used to stably and accurately introduce the aluminum alloy strip into the high-frequency welding unit for subsequent welding and forming processes.

Patent document CN214602481U discloses a high-frequency welding aluminum alloy tube strip introduction device, which cannot guide and slide the two ends of the aluminum alloy strip to ensure that the aluminum alloy strip maintains a stable posture and position during the transmission process. The strip is prone to deviation or shaking during the transmission process, and the strip is easily damaged due to excessive friction or extrusion.

[0004] 2. Patent document CN211521103U discloses a copper-iron alloy tube strip material introduction device, which cannot limit the strip in the vertical direction during the horizontal introduction process. The strip will jump or deviate in the vertical direction during the transmission process.

[0005] 3. Patent document CN215508690U discloses an aluminum alloy tube strip material introduction device, which cannot stably convey the initially unwound strip material to the strip material introduction position, and cannot realize continuous and efficient transmission of the initial strip material loading, resulting in low overall production efficiency.

[0006] 4. Patent document CN113546980A discloses an aluminum alloy strip feeding guide device for an aluminum alloy high-frequency welded pipe production line. The feeding guide device cannot support the aluminum alloy strip during the introduction process.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a strip edge guide assembly on the top of the high-frequency welding machine introduction frame, and the two side ends of the aluminum alloy strip slide on the inner side of the strip edge guide wheel and move in the direction away from the guide frame to be sent to the working position of the high-frequency welding machine. The sliding limit ensures that the aluminum alloy strip maintains a stable posture and position during the transmission process, and prevents the strip from shifting or shaking during the transmission process, thereby ensuring the accuracy and quality of welding. The sliding limit can limit the sliding range and strength of the strip on the inner side of the edge guide wheel, avoid damage to the strip due to excessive friction or extrusion, and protect the surface quality of the strip. Stable strip transmission helps the high-frequency welding machine to perform welding work with higher efficiency, reduce equipment failures and downtime caused by strip deviation or shaking, and enable the high-frequency welding machine to better adapt to aluminum alloy strips of different specifications and materials, and achieve stable transmission and precise welding of different strips.

[0019] 2. The present invention provides a strip bending correction assembly on the top of the strip edge guide assembly.

The bending correction wheel cooperates with the energy absorber to guide and press down the upper surface of the aluminum alloy strip, and adjusts the winding and bending direction of the aluminum alloy strip to restore it to flatness. The anti-jumping downward pressure frame prevents the strip from jumping or deviating in the vertical direction during transmission, ensuring that the strip can smoothly enter the working position of the high-frequency welding machine. The bending correction wheel and the energy absorber are used in coordination to accurately guide and press down the upper surface of the aluminum alloy strip, which helps to eliminate defects such as waves and bends that may occur in the strip during transmission. The winding and bending direction of the strip is adjusted to restore the strip to flatness before welding, thereby further improving the flatness and consistency of welding. Stable strip transmission can reduce the impact and wear on the high-frequency welding machine and its supporting equipment. The parameters of the bending correction wheel and the energy absorber are adjusted to achieve accurate guiding and pressing down of strips of different specifications.

[0020] 3. The present invention installs a pulling guide cylinder at the telescopic end of the vertical telescopic hand rod. The pulling guide cylinder clamps and limits the upper and lower surfaces of the aluminum alloy strip, and then the guide rail seat drives the aluminum alloy strip to move. The pulling guide cylinder transfers the aluminum alloy strip to the strip edge guide assembly. The pulling guide cylinder clamps and limits the upper and lower surfaces of the aluminum alloy strip, which can effectively prevent the strip from slipping or deflecting during transmission, ensure that the strip can be stably and accurately transmitted to the position of the strip edge guide assembly, ensure that the strip maintains a constant tension and position during transmission, so that the high-frequency welder can more accurately control the welding parameters and welding position, which helps to improve the accuracy and consistency of welding and ensure the quality and performance of the welded joints. The coordinated work of the pulling guide cylinder and the guide rail seat can realize the continuous and efficient transmission of the initial loading of the strip, which helps the high-frequency welder maintain a continuous and stable working state and improves the overall production efficiency.

[0021] 4. The present invention installs a strip guiding bevel block on the top of the anti-falling guide support platform, and the anti-falling guide support platform supports the aluminum alloy strip during the process of the strip side guide wheel introducing the aluminum alloy strip, thereby preventing the outer end of the aluminum alloy strip from falling downward when it is initially introduced through one group of strip side guide wheels to another group of strip side guide wheels. The supporting effect ensures the continuity and stability of the strip transmission, and the strip guiding bevel block enables the strip to change direction smoothly when it transitions from one side guide wheel to another. The smooth transition reduces the vibration and impact of the strip during transmission, and ensures that the strip has the correct position and posture when entering the working position of the high-frequency welding machine, thereby improving the accuracy and consistency of welding, and helping to reduce welding defects and the generation of defective products. The coordinated use of the anti-falling guide support platform and the strip guiding bevel block makes the strip transmission process smoother and more efficient, reduces production pauses and delays caused by strip falling or poor transition, and improves the overall production efficiency.

The two side ends of the aluminum alloy strip 15 slide inside the strip side guide wheel 19 and move away from the guide frame 2 to be sent to the working position of the high-frequency welding machine. During the process of the strip side guide wheel 19 introducing the aluminum alloy strip 15, the anti-fall guide support platform 32 supports the aluminum alloy strip 15 to prevent the outer end of the aluminum alloy strip 15 from falling downward when it is initially introduced through one group of strip side guide wheels 19 to another group of strip side guide wheels 19. During the horizontal introduction of the aluminum alloy strip 15, the anti-jump downward pressing frame 5 limits its vertical direction, and the bending correction wheel 31 cooperates with the energy dissipator 29 to guide and press down the upper surface of the aluminum alloy strip 15, adjusting the winding and bending direction of the aluminum alloy strip 15 to restore it to flatness.
