Description

Technical Field

[0001] This utility model belongs to the field of metal sheet and strip post-processing, and specifically relates to a movable support device for unwinding and rewinding equipment, so as to realize the movable support of the unwinding and rewinding equipment. Background Technology

[0002] In the metal sheet and strip post-processing production line, the uncoiler / rewinder is one of the key pieces of equipment. The uncoiler / rewinder is used to support, unfold, and coil the raw steel coil. Currently, cantilever uncoilers / rewinders are mostly used in the sheet and strip post-processing production line. The movable support is used to support the drum support position of the cantilever uncoiler / rewinder to prevent the drum from sagging, so that the two ends of the drum of the uncoiler / rewinder are evenly stressed, stabilize the drum, and not affect the subsequent uncoiling and rewinding. At the same time, the movable support also needs to avoid the upper and lower winding movements and not interfere with the upper and lower winding movements.

[0003] With the development of strip processing lines, the diameter and width of strip coils are gradually increasing. The weight of the steel coils supported by the uncoilers / rewinders has reached over 20 tons, and the production line's requirements for production tension are also increasing. The forces borne by the cantilever structure of the uncoiler / rewinder drums are also increasing. If problems such as sag or instability occur in the uncoiler / rewinder drums, it will greatly affect the production line's output. Therefore, the requirements for the movable supports of the uncoiler / rewinder are becoming increasingly stringent. Currently, the commonly used movable support device on the market is a single-arm cantilever support. This structure has problems such as poor force distribution, multiple drives, heavy equipment, and high cost. It is prone to instability due to force distribution, leading to support failure, which in turn affects the production quality of the strip and the production line's efficiency. Alternatively, other support forms exist, but their structures tend to be more complex and involve more drives. Summary of the Invention

[0046] Figure 1 This is a side view of the movable support device structure of this utility model. Figure 2 This is a schematic diagram of the rotating movable support device of this utility model. (See diagram below.) Figure 1 , 2As shown, this utility model proposes a movable support device 9 for the unwinding and rewinding equipment of a strip post-processing production line. It mainly consists of a base 1, a cantilever 2, a drive mechanism 4, and components such as a rotating shaft seat, a clamping plate, a bushing, and a drive mechanism rotating shaft seat. The concave hub assembly mechanism 3 of the unwinding and rewinding equipment is fixedly installed at one end of the cantilever 2. When the movable support device 9 is in working position A, the concave hub assembly mechanism 3 cooperates with the drum support position 5 of the unwinding / rewinding machine, aligning the concave hub assembly mechanism 3 with the center of the drum support position 5. When the movable support device 9 is in non-working position B, it avoids the steel coil loading / unloading operation position of the unwinding / rewinding machine. The base 1 is fixedly installed on a reference surface P, which can be the ground, a wall, or the working surface of a work platform. The cantilever 2 is movably connected to the base 1. One end of the drive mechanism 4 is connected to the reference surface P, for example, directly to the reference surface P, or to the base 1 fixedly installed on the reference surface P. The other end of the drive mechanism 4 is connected to the cantilever 2. The drive mechanism 4 drives the cantilever 2 to rotate around the base 1 to the working position A or the non-working position B. In a specific embodiment of this utility model, the cantilever 2 includes a main arm 2-1, a swing arm 2-3, and a rotating shaft 2-3. One end of the main arm 2-1 is fixedly connected to one end of the swing arm 2-2. The rotating shaft 2-3 is located at the connection between the main arm 2-1 and the swing arm 2-2. The cantilever 2 is movably connected to the base 1 through the rotating shaft 2-3. The other end of the swing arm 2-2 is connected to the other end of the drive mechanism 4. The concave hub assembly 3 is fixedly located at the other end of the main arm 2-1. The drive mechanism 4 can be a hydraulic cylinder, a pneumatic cylinder, or a linear motor, and this utility model is not limited thereto. A safety pin 2-4 is provided on the swing arm 2-2. When the movable support device 9 is in the non-working position B, the main arm 2-1 is fixedly connected to the base 1 by the safety pin 2-4.

[0047] Figure 3A , 3B 3C is a schematic diagram of the cantilever structure of the movable support device of this utility model. (See diagram for example.) Figure 3A , 3B As shown in Figures 3C and 4C, a limiting part C is provided on one end of the main arm 2-2 of the movable support device 9 of this utility model, facing away from the non-working position B. The limiting part C is right-angled. When the main arm 2-2 rotates to the working position A (the movable support device 9 is in the working position A), the limiting part C abuts against the baffle 1-1 of the base 1. In this way, the main arm 2-1 can be restricted from continuing to rotate in the direction away from the non-working position B, which can prevent the cantilever from tipping over and at the same time reduce the selection of the drive mechanism.

[0048] Please refer to it again. Figure 1An anchor rod 6 is also provided below the base 1. The anchor rod 6 is a steel pipe or steel bar, which can be fixed to the ground or wall of the reference surface P by pre-embedding or driving in, so as to stabilize the movable support device 91, prevent the movable support device 9 from overturning, and reduce the stress at the connection point (e.g., bolt) between the movable support device 9 and the reference surface P. In the embodiment of this utility model, the anchor rod 6 is a square tube, which is welded to the bottom of the base 1.

[0049] Figure 4 This is a schematic diagram of the concave hub assembly mechanism of the unwinding and rewinding equipment. (For example...) Figure 4 As shown, the concave hub assembly mechanism 3 includes a concave hub 3-1, a concave hub bracket 3-2, a concave hub shaft 3-3, a pressure cap, an end cap, a bearing, a sealing ring, adjusting bolts, and adjusting shims. The uncoiler / rewinder is equipped with a floating cylinder and guide rails, enabling automatic centering of the strip steel. The concave hub assembly mechanism 3 was designed specifically for this feature. Through the bearings, concave hub shaft 3-3, and concave hub 3-1, it can rotate accordingly, suitable for the forward and backward movement of the uncoiler / rewinder during unwinding or rewinding. The adjusting bolts and adjusting shims prevent errors during on-site installation. Adjustments are made up-down and left-right using the adjusting bolts and adjusting shims to ensure the center of the concave hub aligns with the center of the uncoiler / rewinder's drum support 5, providing stable support.

[0050] Figure 5A , 5B This is a schematic diagram of the working state of the unwinding and rewinding equipment of this utility model. Figure 5A , 5B As shown, when the unwinding and rewinding equipment performs unwinding and rewinding operations, the cantilever 2 rotates to the working position. During the unwinding action, when the steel coil 8 needs to be transported to the drum 7-1 of the unwinding / rewinding machine 7, the cantilever 2 of the movable support device 9 rotates to the non-working position to avoid the movement of transporting the steel coil. After the coiling is completed, the cantilever 2 of the movable support device 9 rotates to the working position to support the drum support position 5 of the unwinding / rewinding machine 7, reducing the sag of the drum, and then the subsequent unwinding work is carried out. After the unwinding is completed, the auxiliary support is in the non-working position, and the sleeve on the drum is removed, and the cycle repeats. The movable support action during the rewinding operation is the same and will not be described again.

[0051] Compared with existing technologies, this utility model's movable support device has a more reasonable force distribution and more stable support, while enhancing the strength and rigidity of the movable support, improving the safety of the production line and ensuring the stability of unwinding and rewinding. It is applicable to all cantilever structure unwinding / rewinding mechanisms and can simultaneously accommodate strip post-processing production lines with large roll weight, high tension, and wide strips. Furthermore, by simplifying the structural design, it reduces the equipment's weight, the number of drives, and their size, thus lowering costs. This utility model's movable support device boasts advantages such as reliable operation, simple operation, smooth rotation, and low impact force.

[0052] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
