[0002] As a key equipment in modern steel production, the rolled steel coil baler plays a vital role. It is mainly responsible for rolling and packing the steel coils that have been processed by the rolling process to ensure that the steel coils can be neatly stored and safely transported. With the continuous development and progress of the global steel industry, the requirements for the quality and efficiency of steel coil packaging are also constantly increasing. Traditional rolled steel coil balers often have control redundancy in the process of tight coiling, and their mechanism design is complex, which leads to the need for cumbersome adjustments for steel coils of different diameters in actual operation. For example, the operator must adjust the stroke of the tight coil moving frame to adapt to steel coils of different sizes. This process is not only time-consuming but also prone to errors. In addition, these traditional equipment often have technical problems such as mechanism jamming and vertical rolling roller being squeezed and distorted during the tight coiling process. These problems not only directly affect the rhythm of production, but also have a negative impact on the quality of packaging. These faults not only increase the maintenance cost of the equipment, but also significantly reduce the overall work efficiency, thereby affecting the economic benefits of steel enterprises.

[0015] Technical advantages of the self-aligned tight winding device

[0016] 1. High-precision centering: The automatic centering of the steel coil is achieved through the synchronous movement of the mobile frame. The accuracy of this process is much higher than that of manual positioning operation. This high-precision centering technology ensures the accurate alignment of the steel coil during the production process, thereby improving the overall production efficiency and product quality.

[0017] 2. Efficient operation: The mobile frame adopts synchronous motion technology, which is not only fast but also responsive, which can greatly improve the efficiency of tight winding. This efficient operation method is particularly suitable for large-scale production needs and can meet the strict requirements of speed and efficiency in modern industrial production.

[0018] 3. Reduce equipment failure and damage: By eliminating the centering point spiral cylinder and its control system, the "self-locking" stuck phenomenon of the spiral structure is reduced, thus significantly reducing the occurrence of failures. This design not only extends the service life of the equipment, but also reduces maintenance costs, saving the company a lot of unnecessary expenses.

[0019] 4. Flexible adjustment: Due to the compressibility of the cylinder gas, the tight roll will no longer be damaged by hard bearing, and by adjusting the size of the air pressure, the tight roll strength can be flexibly adjusted. This adjustment method improves the reliability and adaptability of the operation, ensuring the stability of the production process and the high quality of the product.

[0031] The cylinder mechanism 4 is located outside the active moving frame, and the cylinder rod of the cylinder mechanism 4 is perpendicular to the two moving frames 2;

[0032] The vertical rolling rollers 5 are arranged on the upper surfaces of both ends of the moving frame 2 .

[0033] Specifically: the passive moving frame is mounted on the passive sliding slide 61, and the passive sliding slide includes two slide beams parallel to the chain and two fastening beams vertically connected to the two slide beams, and the two slide beams and the two fastening beams form a square shape.

[0042] A moving frame is arranged on the base, and the moving frame is placed on the sliding track of the base. In order to realize the smooth movement of the moving frame, two sets of active and passive moving frames are specially designed.

The upper side of the chain is fixed to the side of the active moving frame, and the lower side of the chain is fixed to the side of the passive moving frame to ensure the synchronization and accuracy of the moving frame.
