[0003] Existing metal strip straightening equipment generally suffers from the following problems: Currently, during operation, adjustments can only be made to the gap between the upper and lower straightening rollers. However, prolonged operation can cause the upper straightening roller to deflect, resulting in the axis of the upper straightening roller not being parallel to the axis of the lower straightening roller. This leads to incomplete straightening of the metal strip, thus affecting product quality. Currently, adjustments can only be made manually by disassembling the upper straightening roller to adjust its angle, which is time-consuming, labor-intensive, has poor adjustment accuracy, and is inconvenient to operate.

[0004] Therefore, there is an urgent need for an adjustment device that can precisely adjust the height and angle of the straightening rollers to improve the accuracy and efficiency of metal strip straightening and ensure product quality. Utility Model Content

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] Example 1

[0038] The straightening rollers include a first straightening roller 1 and a second straightening roller 2. The first straightening roller 1 is located above the second straightening roller 2. The position of the second straightening roller 2 is relatively fixed, and the axis of the second straightening roller 2 extends along a first direction.

[0039] This example provides a straightening wheel adjustment device, which is used to adjust the distance between the first straightening wheel 1 and the second straightening wheel 2, and to adjust the first straightening wheel 1 so that the axis lines of the first straightening wheel 1 and the second straightening wheel 2 are parallel or nearly parallel.

[0040] The adjustment device includes a fixed frame 3, a lifting adjustment mechanism 4, and an angle adjustment mechanism 5. The lifting adjustment mechanism 4 is mounted on the fixed frame 3 and is connected to the angle adjustment mechanism 5 to drive the angle adjustment mechanism 5 to move along a second direction, causing the first straightening wheel 1 to move closer to or further away from the second straightening wheel 2, thereby adjusting the distance between the first straightening wheel 1 and the second straightening wheel 2. The first direction is defined as the X-axis, and the second direction as the Z-axis. The lifting adjustment mechanism 4 drives the angle adjustment mechanism 5 to move along the Z-axis, causing the first straightening wheel 1 to move upward or downward.

[0041] Angle adjustment mechanism 5 is used to adjust the first straightening wheel 1 so that the axis lines of the first straightening wheel 1 and the second straightening wheel 2 are parallel or nearly parallel. Angle adjustment mechanism 5 includes a first support 51, a second support 52, a first adjusting member 54, and a second adjusting member 55. The first support 51 is connected to the lifting adjustment mechanism 4. The first straightening wheel 1 is connected to the second support 52. The second support 52 and the first support 51 are rotatably connected through a central shaft 53. The central shaft 53 extends along a third direction, which is the Y-axis.

[0042] The first adjusting member 54 and the second adjusting member 55 are arranged side by side and both extend along the second direction. The first adjusting member 54 and the second adjusting member 55 are both connected to the first support member. One end of the first adjusting member 54 and one end of the second adjusting member 55 pass through the first support member 51 and press against the upper side of the second support member 52 (the upper side is horizontal). The first adjusting member 54 is used to push one end of the upper side of the second support member 52 to rotate. The rotation of the second support member 52 drives the first straightening wheel 1 to rotate. The second adjusting member 55 is used to push the other end of the upper side of the second support member 52 to rotate. The rotation of the second support member 52 drives the first straightening wheel 1 to rotate. The first direction, the second direction and the third direction are perpendicular to each other.

[0043] Referring to the figure, the first support 51 includes a first support plate 511 and a second support plate 512. The first support plate 511 is connected to the drive shaft of the angle adjustment mechanism 5, and the second support plate 512 is connected to one side of the first support plate 511. The second support plate 512 and the second support 52 (U-shaped bracket) are rotatably connected via a central shaft 53. The output ends of the first adjusting member 54 and the second adjusting member 55 both pass through the first support plate 511 and abut against the second support 52. The second support plate 512 has a first arc-shaped hole 5121 and a second arc-shaped hole 5122. The first arc-shaped hole 5121 and the second arc-shaped hole 5122 are respectively located on opposite sides of the central shaft 53. Two arc-shaped holes 5122 are distributed along the first direction, and both the first arc-shaped hole 5121 and the second arc-shaped hole 5122 protrude away from the central axis 53. One end of a fastener 56 passes through the first arc-shaped hole 5121 and the second support member 52 in sequence to fix the second support plate 512 and the second support member 52. The other end of a fastener 56 passes through the second arc-shaped hole 5122 and the second support member 52 in sequence to fix the second support plate 512 and the second support member 52. When it is necessary to operate the first adjusting member 54 and the second adjusting member 55 to adjust the first straightening wheel 1, the fastener 56 is loosened first and then the first adjusting member 54 and the second adjusting member 55 are operated. After the adjustment is completed, the fastener 56 is tightened again.

[0044] Preferably, both the first adjusting member 54 and the second adjusting member 55 are micrometer heads, and the output ends of the two micrometer heads abut against the same side of the second support member 52. By rotating the micrometer head, the micrometer head can push the second support member 52. The micrometer head has a high-precision adjustment capability, which can achieve minute angle adjustments and ensure straightening accuracy.

[0045] In a preferred embodiment, two second support plates 512 are provided, and the two second support plates 512 are respectively connected to the opposite sides of the first support plate 511, resulting in better structural stability.

[0046] In this example, the second support 52 is inverted U-shaped and includes a top plate and two side plates. The two side plates are respectively located at both ends of the same side of the top plate, forming an inverted U-shape. The opening of the inverted U-shape faces the second straightening wheel 2, and the first straightening wheel 1 is installed in the space of the second support 52. The second support 52 has high structural strength and provides a stable installation space for the first straightening wheel 1.

[0047] In some embodiments, each of the two side plates of the second support 52 is provided with a plurality of mounting holes 521 along its length, which facilitates the installation of the first straightening wheel 1 at different positions within the second support 52, thus providing greater flexibility.

[0048] In some embodiments, the first support 51 further includes a third support plate 513, which is connected to the second support plate 512. One end of the drive shaft of the lifting adjustment mechanism 4 passes through the third support plate 513 and is connected to the first support plate 511. The device also includes a first guide 10, which extends along a second direction and is disposed on the third support plate 513, allowing the third support plate 513 to move along the first guide 10. With the first guide 10 in place, when the first straightening wheel 1 moves along the second direction, the movement is smooth without deviation or wobbling, resulting in high adjustment accuracy.

[0049] In some embodiments, the adjusting device further includes a first locking member 9, which is sleeved on the drive shaft of the lifting adjusting mechanism 4. The first locking member 9 is used to lock the drive shaft of the lifting adjusting mechanism 4. Referring to the figure, the first locking member 9 can be a clamp with a U-shaped structure. The first locking member 9 can be connected to other fixed structures. Openings are provided on both opposite sides of the first locking member 9. One end of a fastening connector passes through the two openings in sequence to connect the opposite sides of the first locking member 9, so that the first locking member 9 is locked to the drive shaft of the lifting adjusting mechanism 4, and the drive shaft cannot rotate. When the lifting adjusting mechanism 4 is to be operated, the fastening connectors on both sides of the first locking member 9 are loosened first, and then the fastening connectors are tightened after the lifting adjusting mechanism 4 is operated. The first locking member 9 can fix the position of the lifting adjusting mechanism 4 after adjustment, preventing the adjustment position from changing due to vibration or other reasons during use.

[0050] In this example, the lifting adjustment mechanism 4 includes a knob and a screw. The screw extends along the Z-axis. The knob is connected to one end of the screw, and the other end of the screw is connected to the angle adjustment mechanism 5.

[0051] The specific implementation of the straightening wheel adjustment device in this example is as follows: If the first straightening wheel 1 is tilted, that is, the center lines of the first straightening wheel 1 and the second straightening wheel 2 are not parallel, such as if one end of the first straightening wheel 1 is positioned higher than the other end, the first adjusting member 54 is operated to push one end of the second support member 52 to rotate until the center lines of the first straightening wheel 1 and the second straightening wheel 2 are parallel; if the other end of the first straightening wheel 1 is positioned higher than one end, the second adjusting member 55 is operated to push one end of the second support member 52 to rotate until the center lines of the first straightening wheel 1 and the second straightening wheel 2 are parallel. If the distance between the first straightening wheel 1 and the second straightening wheel 2 increases or decreases, the lifting adjustment mechanism 4 is operated.

[0052] In this example, the operator can adjust the height of the first straightening roller 1 by rotating the knob of the lifting adjustment mechanism 4; the angle of the first straightening roller 1 can be changed by adjusting the first adjusting member 54 and the second adjusting member 55. When fine angle adjustment of the first straightening roller 1 is required, the first adjusting member 54 and the second adjusting member 55 are operated to rotate the second support member 52 around the central axis 53 to adjust the angle of the first straightening roller 1. After adjustment, the adjusted position is locked by the fastener 56 and the first locking member 9 to ensure stability and accuracy during the straightening process.

[0053] The straightening wheel adjustment device in this example has a compact structure and is easy to operate. It can achieve precise height and angle adjustment of the first straightening wheel 1, meet the straightening requirements of workpieces of different specifications, and improve straightening quality and efficiency.

[0054] Example 2

[0055] The difference between this example and Example 1 is: See [link / reference] Figure 6 The first straightening roller 1 and the second straightening roller 2 are distributed left and right, and the adjustment devices are set in different directions. The first direction is set as the Z-axis, the second direction as the X-axis, and the third direction as the Y-axis.

[0056] The lifting adjustment mechanism 4 is used to drive the angle adjustment mechanism 5 to move along the X-axis, so that the first straightening wheel 1 moves to the left or right.

[0057] The first adjusting member 54 and the second adjusting member 55 both extend along the X-axis, and the central axis 53 extends along the Y-axis. The output ends of the first adjusting member 54 and the second adjusting member 55 press against the left or right side of the second support member 52 (this side extends along the Z-axis).

[0058] Example 3

[0059] This example provides a metal strip straightening device; see [link / reference] Figure 4-56-7. The straightening device includes a first adjusting mechanism, a second adjusting mechanism, a first mounting mechanism, and a second mounting mechanism. The first adjusting mechanism cooperates with the first mounting mechanism, and the second adjusting mechanism cooperates with the second mounting mechanism. The first adjusting mechanism includes the straightening wheel adjusting device of Embodiment 1, and the second adjusting mechanism includes the straightening wheel adjusting device of Embodiment 2. The first adjusting mechanism and the second adjusting mechanism have different orientations. In the first adjusting mechanism, the first direction is the X-axis, the second direction is the Z-axis, and the third direction is the Y-axis; in the second adjusting mechanism, the first direction is the Z-axis (the center line of the straightening wheel), the second direction is the X-axis, and the third direction is the Y-axis. The metal strip wound on the collection roll is straightened sequentially by the first adjusting mechanism and the second adjusting mechanism, or the metal strip wound on the collection roll is straightened sequentially by the second adjusting mechanism and the first adjusting mechanism.

[0060] In this example, the first mounting mechanism is used to fix the second straightening wheel 2. The first mounting mechanism includes a first mounting frame 6, which is U-shaped. The second straightening wheel 2 is mounted on the first mounting frame 6 and can rotate around its own axis.

[0061] The second mounting mechanism is used to fix the second straightening wheel 2. In some embodiments, the second mounting mechanism includes a base platform 8 and a second mounting frame 7. The second mounting frame 7 is disposed on the base platform 8, and the second straightening wheel 2 is connected to the second mounting frame 7. The second straightening wheel 2 can rotate around its own axis. The equipment also includes a displacement adjustment mechanism 11, which is connected to the second mounting frame 7 and used to drive the second mounting frame 7 to move in a second direction. Through the displacement adjustment mechanism 11, the position of the second straightening wheel 2 can be adjusted to meet the straightening requirements of metal strips of different specifications.

[0062] In some embodiments, the metal strip straightening device further includes a second locking member 12, which is sleeved on the drive shaft of the displacement adjusting mechanism 11. The second locking member 12 is used to lock the drive shaft of the displacement adjusting mechanism 11, and has the same structure as the first locking member 9. The metal strip straightening device also includes a connecting block 14 and a second guide member 13. The connecting block 14 is connected to the second mounting bracket 7, and the second guide member 13 is disposed on the connecting block 14 and the base 8. The second guide member 13 extends along a second direction, and the connecting block 14 can move along the second guide member 13. The second locking member 12 can be connected to the connecting block 14. With the second guide member 13, when the second straightening wheel 2 moves along the second direction, the movement is smooth without deviation or shaking, and the adjustment accuracy is high. When the displacement adjusting mechanism 11 is to be operated, the fastening connecting members on opposite sides of the second locking member 12 are first loosened, and then the fastening connecting members are locked after the displacement adjusting mechanism 11 is operated. The connecting block 14 is then connected to the base 8.

[0063] During operation, the metal strip passes sequentially between the first adjusting mechanism and the first mounting mechanism, and between the second adjusting mechanism and the second mounting mechanism. The first and second straightening rollers apply pressure to the metal strip and guide its passage, achieving a holistic straightening effect. By adjusting the lifting and angle adjustment mechanisms within the first and second adjusting mechanisms, the height and angle of the first straightening roller can be precisely controlled. Adjusting the position of the second mounting frame via the displacement adjustment mechanism changes the position of the second straightening roller, thus adapting to the straightening requirements of metal strips of different specifications. This metal strip straightening equipment is flexible in adjustment, enabling precise straightening of the metal strip and improving straightening quality and efficiency.

They should not be construed as limiting the scope of protection of this utility model.
