Description

Technical Field

[0001] This utility model relates to the field of steel coil tensioning technology, specifically a steel coil tensioning mechanism for an uncoiler. Background Technology

[0002] Uncoiling machines are specialized equipment for leveling metal sheets. They are used to level steel plates and uneven plates. Depending on the configuration, they can be used to form uncoiling, leveling, and shearing production lines and other sheet metal product production lines. The design and application of the steel coil tensioning structure on the uncoiler are crucial to ensuring the stability and continuity of the uncoiling process. Currently, although the steel coil tensioning structures widely used in the market can achieve effective tensioning of steel coils to a certain extent, they still have some drawbacks. They have low adjustability and are often difficult to apply to steel coils of different diameters, resulting in low versatility and practicality of the device. Moreover, after a certain amount of uncoiling, the tensioning force is insufficient due to the smaller diameter, which can easily cause loosening and slippage, resulting in insufficient tensioning effect.

[0003] Therefore, we propose a steel coil tensioning mechanism for an uncoiler to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the current steel coil tensioning structure, although it can achieve effective tensioning of steel coils to a certain extent, still has some shortcomings. It has low adjustability and is often difficult to apply to steel coils of different diameters, resulting in low versatility and practicality of the device. Moreover, after a certain amount of coiling is unwound, the tensioning force is insufficient due to the smaller diameter, which easily causes loosening and slippage, resulting in insufficient tensioning effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a steel coil tensioning mechanism for an uncoiler, comprising: a mechanism base, wherein a mechanism cylinder and an uncoiler shaft are disposed on the mechanism base; Multiple anti-loosening structures are installed on the mechanism cylinder. Each anti-loosening structure includes an arc-shaped plate, a limit post is provided on the arc-shaped plate, and a mechanism spring is provided between the arc-shaped plate and the inner wall of the mechanism cylinder. The mechanism cylinder is provided with a limit hole that is slidably connected to the limit post. A drive mechanism is mounted on a mechanism base, and a tension steel wire is provided between the drive mechanism and the arc-shaped plate.

[0006] Furthermore, the driving mechanism includes a connecting ring and a driving motor mounted on the mechanism base. A rotating ring is mounted on the connecting ring, and a retaining tooth is provided on the outer ring surface of the rotating ring. An annular groove adapted to the connecting ring is formed on the inner ring surface of the rotating ring. A driving gear is connected to the output shaft of the driving motor, and the driving gear meshes with the retaining tooth. One end of the pulling steel wire passes through the inner wall of the mechanism cylinder and is connected to the rotating ring.

[0007] Furthermore, the mechanism cylinder has an exit opening on its side, and a pressure roller is provided at the exit opening.

[0008] Furthermore, a plurality of evenly distributed first balls are provided on the inner arc surface of the arc plate.

[0009] Furthermore, the connecting ring is provided with a plurality of evenly distributed second balls, and the inner wall of the annular groove of the rotating ring is provided with ball grooves that are adapted to the second balls.

[0010] Furthermore, the mechanism cylinder is provided with multiple guide wheels that overlap with the pulling steel wire.

[0011] Furthermore, the mechanism base is provided with a shaft hole, and a bearing adapted to the unwinding shaft is provided in the shaft hole.

[0012] The beneficial effects of this utility model are as follows: by setting a mechanism cylinder and an uncoiling shaft on the mechanism seat, the steel coil is sleeved on the uncoiling shaft, and multiple anti-loosening structures are set on the mechanism cylinder. During the uncoiling process of the steel coil, when the diameter of the steel coil decreases, the anti-loosening structures can be automatically adjusted. The arc plate abuts against the surface of the steel coil to prevent loosening and slippage, and maintains the tension effect on the steel coil during the uncoiling process.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0016] Embodiments of this utility model: like Figures 1-4 As shown, this utility model provides a steel coil tensioning mechanism for an uncoiler, including a mechanism base 1, multiple anti-loosening structures 4, and a drive mechanism. The mechanism base 1 is provided with a mechanism cylinder 2 and an uncoiling shaft 3. The mechanism cylinder 2 has an exit opening on its side, and a pressure roller 11 is provided at the exit opening. With this arrangement, the pressure roller 11 can perform preliminary leveling treatment on the steel coil during uncoiling, which facilitates the subsequent leveling work of the steel coil. The mechanism base 1 has a shaft hole, and a bearing 15 adapted to the uncoiling shaft 3 is provided in the shaft hole. With this arrangement, the uncoiling shaft 3 can be connected to an external drive device. like Figures 1-4 As shown, multiple anti-loosening structures 4 are installed on the mechanism cylinder 2. The anti-loosening structure 4 includes an arc plate 41, a limit post 42 is provided on the arc plate 41, and a mechanism spring 43 is provided between the arc plate 41 and the inner wall of the mechanism cylinder 2. A limit hole is provided on the mechanism cylinder 2 to slide and connect with the limit post 42. The arc plate 41 can always press against the surface of the steel coil under the action of the mechanism spring 43. like Figures 1-4 As shown, the drive mechanism is mounted on the mechanism base 1. A tension steel wire 5 is provided between the drive mechanism and the arc plate 41. The drive mechanism includes a connecting ring 6 and a drive motor 7 mounted on the mechanism base 1. A rotating ring 8 is mounted on the connecting ring 6. A retaining tooth 9 is provided on the outer ring surface of the rotating ring 8, and an annular groove adapted to the connecting ring 6 is provided on the inner ring surface of the rotating ring 8. A drive gear 10 is connected to the output shaft of the drive motor 7. The drive gear 10 meshes with the retaining tooth 9. One end of the tension steel wire 5 passes through the inner wall of the mechanism cylinder 2 and is connected to the rotating ring 8. When installing the steel coil, the drive motor 7 drives the drive gear 10 to rotate, causing the rotating ring 8 to rotate. The tension steel wire 5 pulls the arc plate 41 of the anti-loosening structure 4 to move. After the steel coil installation is completed, the drive motor 7 drives the drive gear 10 to reverse, causing the rotating ring 8 to reverse. The arc plate 41 of the anti-loosening structure 4 returns to its original position and moves to abut against the surface of the steel coil to prevent loosening. like Figures 1-4 As shown, a plurality of evenly distributed first balls 12 are provided on the inner arc surface of the arc plate 41, a plurality of evenly distributed second balls 13 are provided on the connecting ring 6, and a ball groove adapted to the second balls 13 is provided on the inner wall of the annular groove of the rotating ring 8. By such arrangement, friction can be reduced. like Figure 1 As shown, the mechanism cylinder 2 is equipped with multiple guide wheels 14 that overlap with the pulling steel wire 5. This arrangement can guide the pulling steel wire 5 and prevent it from becoming scattered and worn.

[0017] Specifically, the drive motor 7 drives the drive gear 10 to rotate. Under the meshing of the drive gear 10 and the clasp 9, the rotating ring 8 rotates. The traction steel wire 5 pulls the arc plate 41 of the anti-loosening structure 4 to move. Then, the steel coil is installed on the uncoiling shaft 3. The drive motor 7 drives the drive gear 10 to reverse, causing the rotating ring 8 to reverse. The arc plate 41 of the anti-loosening structure 4 returns to its original position and moves to abut against the surface of the steel coil to prevent loosening. During the uncoiling process of the steel coil, as the diameter of the steel coil decreases, the arc plate 41 can always abut against the surface of the steel coil under the action of the mechanism spring 43 to prevent loosening and slippage.
