With the advancement of process technology and changes in market demand, the adjustable hot rolling coil-pulling machine has been continuously developed and improved in terms of background technology. The technical evolution of the adjustable hot rolling coil-pulling machine has gone through several stages. The early hot rolling coil-pulling machines had a relatively simple structure and limited functions, and mainly relied on experience for adjustment and control. With the development of automation and intelligent technology, modern hot rolling coil-pulling machines have higher precision and stability, and can meet more complex process requirements. The key technologies of the adjustable hot rolling coil-pulling machine include precise control, efficient transmission, safety protection and other aspects. Among them, precise control technology is the key to achieving high quality and high stability of products; efficient transmission technology helps to improve production efficiency and reduce energy consumption; safety protection technology ensures the safety of equipment and operators.

[0003] After consulting relevant patent documents, it is found that there are still some problems with the existing adjustable hot rolling coil drawing machine. The optimization solutions currently on the market are mainly: by setting a sliding structure inside the main roller device, the drive shaft can be pulled out from the main roller, so as to take out the processed metal products. However, repeated such operations will cause the connection between the drive shaft and the main roller to loosen on the one hand, and on the other hand, when the metal product is heavy, it is difficult to manually take out the metal product, which may cause the metal to hit the transporter and cause injury. In view of the above problems, an adjustable hot rolling coil drawing machine is proposed, which can automatically close the limit area and automatically unload the processed metal products.

[0013] 1. This type of adjustable hot rolling coiling machine is provided with a closing mechanism. When the metal product is curled on the main roller, the motor is started first. At this time, the motor rotates counterclockwise to drive the driving gear to rotate. The driving gear is meshed with the tooth pattern on the ring. Therefore, the ring rotates counterclockwise at this time, driving the coupling shaft so that the coupling shaft pulls the protrusion on the closing blade, so that the closing blade rotates around the first rotating shaft toward the inner edge of the interlayer, thereby closing the restriction and preventing the metal product from falling off the main roller. When the metal processing is completed, the motor is reversed at this time, so that the coupling shaft on the ring can push the closing blade to rotate toward the outer edge of the interlayer, thereby opening the restriction. At this time, the inner part of the interlayer is hollow and unobstructed, and the finished metal product can be taken out from the main roller. It is simple, convenient and practical.

[0014] 2. This type of adjustable hot rolling coil drawing machine is equipped with connecting rods and hydraulic rods. When the metal product is processed and the closed blades are in the open state, the positioning bolts are loosened first, and then the hydraulic rod is extended to push the connecting rod to move and drive the first support rod to move in the slide groove. At the same time, the semicircular ring on the connecting rod will push the finished metal product out together, so that one end of the finished metal product is placed on the driven shaft, and the other end will be limited by the interlayer and will not shake, so that the finished metal product can be unloaded smoothly, saving labor costs, avoiding heavy metal products from falling and injuring people, and has high safety.
