Description

Technical Field

[0001] The utility model belongs to the technical field of steel coil packaging, and particularly relates to a steel coil edge wrapping and rewinding mechanism. Background Art

[0002] After steel coils are rolled, coated, and finished, they need to be packaged to protect the product and facilitate storage and transportation. Conventional steel coil packaging involves placing the coils on a storage saddle, and workers using pneumatic strapping machines to wrap the strapping tape around them. This is difficult due to the heavy weight of the coils, and workers constantly have to hold the pneumatic strapping machine. This is time-consuming, labor-intensive, and inefficient, and can also cause the coils to shift in weight and fall on the workers, posing a safety hazard.

[0003] To this end, a steel coil packaging device, published with publication number "CN215884339U," relates to the technical field of steel rolling equipment. It comprises two parallel tracks, a mobile lifting trolley operating on the tracks, and multiple baler supports positioned outside the tracks. Multiple storage saddles are positioned between the two tracks, and multiple sets of ultrasonic ranging sensors corresponding to the storage saddles are positioned outside the tracks. Compared to existing technologies, this device addresses the labor-intensive, low-efficiency, and safety risks inherent in existing steel coil packaging methods.

[0004] However, for the above-mentioned steel coil packaging device, although the steel coil is clamped, and then the hydraulic cylinder drives the steel coil to rise, the second encoder detects the lifting height of the electric clamp, and after it rises to the right position, a pneumatic baler is used to package the steel coil, there are still the following obvious defects during use: the above-mentioned device can only package and protect the surface of the steel coil, and can no longer complete the two side and side edge wrapping operations of the steel coil, so the packaged steel coil needs to be transported to multiple devices for side packaging and side edge wrapping, which will affect the progress of steel coil edge wrapping.

[0010] Preferably, the adsorption pump is connected to a suction pipe, and one end of the suction pipe is connected to one side of the side packaging push plate, and an electric pressure relief valve is provided on the suction pipe, so that the side packaging is pressed tightly against the side of the steel coil and the adsorption force is released through the electric pressure relief valve.

[0011] Preferably, the rotating shaft at one end of the driving roller is movable and extends to the outside of one side of the edging rolling seat, and is transmission-connected to the rotating shaft of a servo motor installed on the outside of the edging rolling seat, so that the steel coil can roll to hem the edging materials protruding at both ends at the two edges of the steel coil.

[0012] Compared with the existing technology, the technical effects and advantages of the utility model are as follows: the steel coil edge wrapping and unwinding mechanism, through the combined use of the side packaging push plate, the edge wrapping card push plate, the downward pressure folding plate, the adsorption pump and the cylinder A and the cylinder B, makes the side packaging piece positioned and adsorbed on one side of the side packaging push plate and pushed to fit on the two side faces of the steel coil, and makes the downward folding plate move down and fit on the two sides of the steel coil to fold the convex surface packaging material, and at the same time makes the steel coil edge wrapping ring piece clamped on both sides of the steel coil by the push of the edge wrapping card push plate and presses and fixes the folding part and the side packaging piece, and then makes the steel coil edge wrapping ring piece clamped on the side corners of the steel coil edge on both sides of the steel coil, thereby realizing the pneumatic edge wrapping processing of the steel coil and the packaging of the side face of the steel coil, and at the same time, the edge wrapping and side packaging can be realized in the steel coil edge wrapping and unwinding mechanism, further improving the progress of steel coil production and packaging.

[0013] By combining the edge wrapping rolling seat and multiple driven rotating rollers and servo motors arranged in the edge wrapping rolling seat, the edge wrapping rolling seat can be docked with the equipment for surface packaging of the steel coil, and the surface-packaged steel coil can be transported to the center position of the edge wrapping rolling seat by driving the transmission rollers, and the servo motor can be used to rotate two of the driven rotating rollers to rotate the surface-packaged steel coil, and the downward pressure folding plate is used to roll and fold the protruding surface packaging stripping materials at both ends of the steel coil, so that the steel coil can be rolled for folding, which is beneficial for the edge wrapping ring to be pressed and fixed during the folding, and further improves the firmness and stability of the steel coil after packaging.
