Description

Technical Field

[0001] The utility model relates to the technical field of steel coil processing, in particular to an unwinding device for coil processing. Background Art

[0002] A steel coil, also known as a rolled steel, is a common product form in the iron and steel manufacturing industry. It is formed by subjecting a steel plate to hot rolling or cold rolling processes to shape it into a continuous long strip, and then coiling it into a cylindrical shape for easy storage and transportation. Steel coils are widely popular due to their ease of handling, low transportation costs, and ability to meet various processing requirements. Steel coils are widely used in multiple fields such as construction, automobiles, ships, household appliances, machinery manufacturing, and bridge construction, and have become one of the indispensable basic materials in modern industry.

[0003] When processing steel coils, an unwinding device is required. Through the unwinding device, the steel coil can be rotated to release the winding for subsequent processing.

[0004] An existing unwinding device for coil processing has the following deficiencies: the inner support mechanism for supporting the inner wall of the steel coil has only unilateral support, and unilateral support may cause the steel coil to shift or tilt during unwinding, affecting the stability and straightness of unwinding. Unbalanced support may cause the steel coil to suddenly slip or get out of control, posing a safety hazard to operators, especially during the handling of heavy steel coils, where this risk is more prominent.

[0025] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model will be given in conjunction with the drawings of the specification.

[0026] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] Secondly, the so-called "embodiment" herein refers to specific features, structures or characteristics that can be included in at least one implementation manner of the present utility model. The "in one embodiment" appearing in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments. Embodiment

[0028] Referring to Figures 1-5 , this embodiment provides a pay-off device for coil processing, including a frame, a power mechanism arranged on the frame, the output end of the power mechanism is the inner support mechanism 1, and both the inner support mechanism 1 and the power mechanism are prior arts and will not be elaborated here; a coil feeding mechanism 2 is slidably arranged on the frame, and the sliding direction of the coil feeding mechanism 2 is parallel to the axis direction of the inner support mechanism 1. When receiving a steel coil, the coil feeding mechanism 2 can be used to transport the steel coil so that the inner support mechanism 1 passes through the steel coil;

[0029] a stabilizing mechanism 3 for supporting the end of the inner support mechanism 1 far from the power mechanism is arranged on the frame, and the stabilizing mechanism 3 is located between the coil feeding mechanism 2 and the inner support mechanism 1;

[0030] The stabilizing mechanism 3 includes a first lifting mechanism disposed on both sides of the frame. The output end of the first lifting mechanism is a lifting plate 5. A power shaft 6 is rotatably installed on the lifting plate 5. As Figure 2 shown, the power shaft 6 is higher than the inner support mechanism 1 to prevent collision with it when the steel coil moves. One end of a swing arm 7 is arranged on the power shaft 6. The other end of the swing arm 7 is slidably provided with a slider 8 through an adjusting mechanism. As Figure 4 shown, support wheels 9 are rotatably installed on both sides of the slider 8. The sliding direction of the slider 8 is the length direction of the swing arm 7. The slider 8 is slidably installed on the swing arm 7. The purpose of such a setting is to adjust the end positions of the slider 8 and the support wheels 9 so that when the support wheels 9 reach the extreme positions, the two support wheels 9 are exactly tangent to the central axis of the inner support mechanism 1;

[0031] In this embodiment, during use, first rotate the power shaft 6 to make the swing arm 7 in the Figure 1 and Figure 2 states shown in the figures. Then operate the first lifting mechanism to make the support wheels 9 reach the extreme positions. Then operate the adjusting mechanism so that the support wheels 9 are tangent to the central axis of the inner support mechanism 1 and the support wheels 9 are located below the side of the central axis of the inner support mechanism 1;

[0032] When transporting the steel coil, rotate the power shaft 6 to make the swing arm 7 in a horizontal state so that it will not collide with the steel coil. Then place the steel coil on the coil feeding mechanism 2 and make the steel coil approach the inner support mechanism 1. Before the steel coil overlaps with the inner support mechanism 1, operate the coil feeding mechanism 2 to make the inner support mechanism 1 coaxial with the steel coil. Then make the steel coil approach the power mechanism until the inner support mechanism 1 passes through the steel coil and stops. Then operate the inner support mechanism 1 to fix the steel coil. Then make the coil feeding mechanism 2 return to the initial position. Then rotate the power shaft 6 to make the support wheels 9 reach directly below the central axis of the inner support mechanism 1. Then operate the first lifting mechanism to make the support wheels 9 move upward to be tangent to the central axis of the inner support mechanism 1, so that both ends of the inner support mechanism 1 are supported, improving the stability of the steel coil during rotation.

[0033] As a preferred solution of the present utility model, the adjusting mechanism includes a lead screw 10 rotatably connected to the swing arm 7. The slider 8 is slidably connected to the swing arm 7;

[0034] The lead screw 10 is threadedly connected to the slider 8; the lead screw 10 is threadedly connected with nuts. There are two nuts, respectively located on both sides of the slider 8;

[0035] In this embodiment, by rotating the lead screw 10, since the lead screw 10 is threadedly connected to the slider 8 and the slider 8 is slidably connected to the swing arm 7, rotating the lead screw 10 can make the slider 8 move along the length direction of the swing arm 7, thereby adjusting the initial position and the end position of the slider 8, and can more quickly adjust the support wheels 9 to a state tangent to the central axis of the inner support mechanism 1, which is more convenient.

[0036] As a preferred embodiment of the present utility model, the first lifting mechanism includes a fixed frame 11 fixedly connected to the frame. The lifting plate 5 is slidably connected to the fixed frame 11. More specifically, a stabilizing shaft 12 is fixed to the fixed frame 11, and the lifting plate 5 is slidably connected to the stabilizing shaft 12. The sliding direction of the lifting plate 5 is the vertical direction;

[0037] The fixed frame 11 is fixedly connected with a connecting plate 13. A first driving mechanism 14 is fixed to the connecting plate 13. The first driving mechanism 14 is a cylinder. One end of a first driving rod 16 is rotatably connected to both sides of the connecting plate 13 through a first fixed shaft 15. One end of a second driving rod 18 is rotatably connected to both sides of the bottom of the lifting plate 5 through a second fixed shaft 17. The first fixed shaft 15 is directly below the second fixed shaft 17. The output end of the first driving mechanism 14 is a push plate 19. One end of a third driving rod 20 is rotatably connected to both sides of the push plate 19. The other end of the third driving rod 20 is rotatably connected to the other end of the first driving rod 16 and the other end of the second driving rod 18 through a pin shaft 21. The first driving rod 16 and the second driving rod 18 form a V shape, and the other end of the first driving rod 16 and the other end of the second driving rod 18 face the push plate 19;

[0038] In this embodiment, as Figure 3 and Figure 5 shown, the pin shaft 21 is between the first fixed shaft 15 and the second fixed shaft 17. The first driving rod 16, the second driving rod 18, and the third driving rod 20 are all in an inclined state. When the first driving mechanism 14 drives the push plate 19 to move upward, one end of the third driving rod 20 is driven to move upward. Since the other end of the third driving rod 20 is rotatably connected to the other end of the first driving rod 16 and the other end of the second driving rod 18 through the pin shaft 21, the pin shaft 21 is pushed away from the first driving mechanism 14. When the first driving mechanism 14 reaches the limit position, at this time, the first fixed shaft 15, the second fixed shaft 17, and the pin shaft 21 are in the same straight line. When the support wheel 9 is subjected to the pressure of the inner support mechanism 1, the lifting plate 5 has a tendency to move downward. At this time, the first fixed shaft 15, the second fixed shaft 17, and the pin shaft 21 are in the same straight line, and the force received is offset, playing a self-locking role. After the support is completed, operate the first driving mechanism 14 to lower the push plate 19, and the third driving rod 20 pulls the first driving rod 16 and the second driving rod 18 to rotate, so that the lifting plate 5 and the like descend.

[0039] As a preferred embodiment of the present utility model, a driving mechanism 22 is provided at the end of the power shaft 6. The driving mechanism 22 is a servo motor. By controlling the driving mechanism 22, the rotation of the rotating shaft can be controlled, which is more convenient without manual control.

[0040] As a preferred embodiment of the present utility model, the coil feeding mechanism 2 includes a coil feeding trolley 23. On the coil feeding trolley 23, a V-shaped plate 25 for placing steel coils is installed through a second lifting mechanism 24. The second lifting mechanism 24 uses an oil cylinder. The height of the V-shaped plate 25 can be controlled through the oil cylinder. The steel coils are placed on the V-shaped plate 25, and the steel coils can be automatically positioned.

[0041] As a preferred embodiment of the present utility model, a drive shaft 26 is rotatably connected to the frame. One end of the drive shaft 26 is rotatably connected to a pressing wheel 28 through an extension bracket 27. One end of a second drive mechanism 29 is rotatably connected to the frame. One end of a fixed arm 30 is fixedly connected to the drive shaft 26. The other end of the second drive mechanism 29 is rotatably connected to the other end of the fixed arm 30. The second drive mechanism 29 uses a cylinder;

[0042] In this embodiment, by controlling the second drive mechanism 29 to rotate the drive shaft 26 and the like, the pressing wheel 28 can be pressed on the steel coils, which plays a role in preventing the steel coils from being misaligned.

[0043] As a preferred embodiment of the present utility model, a key is installed between the power shaft 6 and the swing arm 7 to prevent relative rotation between the power shaft 6 and the swing arm 7.

[0044] It should be understood that in the development process of any actual implementation, such as in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those ordinary technical personnel who benefit from this disclosure, without excessive experimentation, the development efforts will be a routine work of design, manufacturing and production.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not restrictive. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
