DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The features and exemplary embodiments of various aspects of the present utility model will be described in detail below. To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present utility model can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present utility model by showing examples of the present utility model.
[0019] As Figure 1 and Figure 2 shown, the present utility model provides a technical solution for an uncoiler for hot rolling of steel: including a bottom plate 11. The bottom plate 11 serves as the support structure of the equipment and bears the weight of the entire equipment. The design of the bottom plate 11 adopts a symmetrical structure, which is beneficial to improving the balance performance of the equipment. The vertical plates 12 symmetrically arranged on the bottom plate 11 play a role in fixing and supporting. The space between the vertical plates 12 is used to install a leveling assembly, and the leveling assembly mainly includes a main roller 21. The shaft ends on both sides of the main roller 21 are rotationally connected to the vertical plates 12, enabling the main roller 21 to rotate freely between the vertical plates 12. This design is beneficial to improving the leveling effect and ensuring the surface quality of the processed products. On the bottom plate 11, a motor 22 is also installed. The motor 22 is the power source of the equipment, converting electrical energy into mechanical energy to drive the main roller 21 and other components to operate. The output end of the motor 22 is connected to a main belt pulley 23, and a transmission belt pulley 24 is arranged obliquely above the main belt pulley 23, and the two are in transmission cooperation through a belt 25. This design achieves a stable transmission effect and reduces the vibration and noise during the operation of the equipment. At the same time, a leveling roller 26 is arranged in the shaft hole of the transmission belt pulley 24 and is used in cooperation with the main roller 21. The leveling roller 26 is rotationally connected to the vertical plates 12 and can level the material during the operation of the equipment. This design ensures the flatness of the material during the processing process and improves the product quality and efficiency.
[0020] Through the mutual cooperation of the bottom plate 11, vertical plates 12, leveling assembly, main roller 21, motor 22, main belt pulley 23, transmission belt pulley 24, leveling roller 26, and belt 25, this solution realizes an efficient, stable, and precise processing process.
[0021] In this embodiment, the steel coil is placed between the main roller 21 and the leveling roller 26, the motor 22 is turned on, the motor 22 drives the main belt pulley 23 to operate, and through the transmission of the belt 25, the transmission belt pulley 24 and the leveling roller 26 are driven to move. The leveling roller 26 performs extrusion leveling by means of the action of the main roller 21 on the steel coil.
[0022] As Figure 1 and Figure 3As shown in the figure, fixing seats 31 are embedded on the opposite outer walls of two vertical plates 12, and the fixing seats 31 are slidably matched with the vertical plates 12. A cross plate 35 is jointly connected to the tops of the two fixing seats 31. A positioning and feeding assembly is arranged between the opposite fixing seats 31. The positioning and feeding assembly includes a plurality of positioning shafts 32. A reinforcing plate 33 is arranged between the plurality of positioning shafts 32. A plurality of positioning bearings 34 are arranged on each positioning shaft 32.
[0023] In this embodiment, during unwinding, the steel coil passes between the main roller 21 and the flattening roller 26. Through the action of the outer ring of the positioning bearing 34 on the steel coil, rotational cooperation is achieved, thereby assisting in feeding, ensuring the smoothness of the unwinding process, and improving the unwinding efficiency.
[0024] As Figure 1 and Figure 3 As shown in the figure, a driving shaft 41 is arranged at the top of the vertical plate 12, and a first bevel gear 42 is sleeved on the driving shaft 41. A stud 44 is arranged on the fixing seat 31, and a second bevel gear 43 is installed at the top end of the stud 44. The stud 44 is in threaded cooperation with the fixing seat 31, and the first bevel gear 42 is meshed with the second bevel gear 43.
[0025] In this embodiment, when the driving shaft 41 is rotated, the driving shaft 41 drives the first bevel gear 42 to rotate. Through the action of the first bevel gear 42 on the second bevel gear 43, the stud 44 is then driven to rotate. The stud 44 is threadedly connected to the fixing seat 31, and thus the fixing seat 31 can be driven to slide along the direction of the vertical plate 12 to adjust the position of the positioning shaft 32.
