Description

Technical Field

[0001] This utility model relates to the field of galvanized aluminum product manufacturing technology, and more specifically, to an adjustment device for a submerged roller and a stabilizing roller. Background Technology

[0002] During the initial start-up of the submerged roll and stabilizing roll, due to the strip shaking when exiting the zinc pot, the inclined stabilizing roll is always used to stabilize the strip. Controlling the strip shaking when exiting the zinc pot causes great damage to the submerged roll and stabilizing roll during the early break-in period. In the early stage, the low pressure scraper is very prone to not rotating, jamming, or losing rotation. In the later break-in period, there are slag edges on the roll surface, which leads to unsatisfactory wear on the bearing bush and bushing, and high-frequency vibration marks appear on the stabilizing roll.

[0003] Currently, in the actual use of submerged rolls and stabilizing rolls, the distance between the two stabilizing rolls is difficult to adjust, which in turn makes it difficult to improve the break-in damage when the strip is discharged.

[0004] Therefore, in view of this, the existing structure is studied and improved to provide an adjustment device for the submerged roller and the stabilizing roller, in order to achieve a more practical purpose. Utility Model Content

[0005] 1. Technical problems to be solved To address the problems existing in the prior art, the purpose of this utility model is to provide an adjustment device for submerged rollers and stabilizing rollers. It can effectively control the shaking problem when the strip exits the zinc pot, greatly reduce the early break-in damage of the submerged rollers and stabilizing rollers, and achieve stable and symmetrical spacing adjustment. It avoids problems such as roller surface slag and wear of bearing bushes and bushings caused by shaking. At the same time, it can make the spacing adjustment of the stabilizing rollers both precise and stable, meeting different process requirements.

[0006] 2. Technical Solution To solve the above problems, the present invention adopts the following technical solution.

[0007] An adjustment device for a submerged roller and a stabilizing roller includes a double L-shaped bracket for mounting the submerged roller and the stabilizing roller. The number of stabilizing rollers is two, and they are respectively movably mounted on the horizontal end of the double L-shaped bracket through corresponding bushings. The submerged roller is movably mounted on the bottom of the vertical end of the double L-shaped bracket through corresponding bushings, and the submerged roller is located directly below one of the stabilizing rollers. A drive motor is fixedly installed on the horizontal end of the double L-shaped bracket. The output end of the drive motor is connected to a rotating arm via a coupling. A sliding groove is provided on the inner side of the rotating arm, and two long push rods are slidably connected through the sliding groove. The end of the long push rod away from the rotating arm is fixed to the corresponding bushing.

[0008] Furthermore, the drive motor is a reversible stepper motor.

[0009] Furthermore, the long push rod includes a long straight rod and a handle end, the handle end being fixed to the side of the long straight rod and engaged inside the slide groove.

[0010] Furthermore, a limiting sleeve is fixedly installed on the inner side of the double L-shaped bracket, and the long straight rod slides along the limiting sleeve.

[0011] Furthermore, the two handle ends are centrally symmetrical about the central axis of the rotating arm.

[0012] Furthermore, the angle between the rotating arm and the horizontal end of the double L-shaped bracket in space during rotation ranges from 30° to 40°.

[0013] 3. Beneficial Effects Compared with existing technologies, the advantages of this utility model are: This solution effectively controls the shaking problem when the strip exits the zinc pot by precisely adjusting the distance between the two stabilizing rollers, greatly reducing the early break-in damage of the submerged roller and the stabilizing roller. Compared with the traditional inclined top stabilizing roller method, this device can achieve smooth and symmetrical distance adjustment, avoiding problems such as roller surface slag and bearing bush wear caused by shaking. Meanwhile, the use of a stepper motor drive in conjunction with a rotating arm, slide rail, and long push rod transmission mechanism enables micron-level spacing adjustment precision. The rotation range of the rotating arm is controlled between 30° and 40°, and the mechanical transmission ratio design ensures that the spacing adjustment of the stabilizing rollers is both precise and stable, meeting various process requirements.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Example: Please see Figure 1 - Figure 4 An adjustment device for a submerged roller and a stabilizing roller includes a double L-shaped bracket 3 for mounting a submerged roller 1 and a stabilizing roller 2. The number of stabilizing rollers 2 is two, and they are respectively movably mounted on the horizontal end of the double L-shaped bracket 3 through corresponding bushings. The submerged roller 1 is movably mounted on the bottom of the vertical end of the double L-shaped bracket 3 through corresponding bushings, and the submerged roller 1 is located directly below one of the stabilizing rollers 2. A drive motor 4 is fixedly installed on the horizontal end of the double L-shaped bracket 3. The output end of the drive motor 4 is connected to a rotating arm 5 via a coupling. A slide groove 501 is provided on the inner side of the rotating arm 5, and two long push rods 6 are slidably connected through the slide groove 501. The end of the long push rod 6 away from the rotating arm 5 is fixed to the corresponding bushing.

[0018] See Figure 1 , Figure 2 Specifically, drive motor 4 is a stepper motor that can rotate in both directions.

[0019] Furthermore, the drive motor 4 is equipped with a mechanical self-locking mechanism after rotation. This locks the rotation angle after the drive motor 4 rotates a certain angle, thus preventing the rotation angle from changing under pressure or other forces.

[0020] See Figure 1 , Figure 3 , Figure 4 Specifically, the long push rod 6 includes a long straight rod 601 and a handle end 602. The handle end 602 is fixed to the side of the long straight rod 601 and is engaged inside the slide groove 501.

[0021] Specifically, a limiting sleeve 301 is fixedly installed on the inner side of the double L-shaped bracket 3, and the long straight rod 601 slides along the limiting sleeve 301.

[0022] Specifically, the two handle ends 602 are centrally symmetrical about the central axis of the rotating arm 5.

[0023] When the rotating arm 5 rotates, the same force is applied to the two handles 602 at the same time, thereby pushing the two handles 602 to move synchronously and equidistantly in opposite directions, thereby achieving the synchronous movement of the two stabilizing rollers 2 away from or towards each other.

[0024] Furthermore, during this process, the rotational motion is converted into linear motion, which allows for the adjustment of the minute distance of the stabilizing roller 2.

[0025] Specifically, the angle between the rotating arm 5 and the horizontal end of the double L-shaped bracket 3 in space during rotation is 30° to 40°.

[0026] By limiting the rotation range of the rotating arm 5, the distance adjustment range between the two stabilizing rollers 2 can ultimately be controlled.

[0027] Working principle: During the production of galvanized aluminum products, the distance between the two stabilizing rollers 2 needs to be adjusted. During this process: The drive motor 4 operates and controls the rotating arm 5 to rotate. The force exerted by the slide groove 501 on the handle end 602, combined with the sliding restriction of the limit sleeve 301 on the long straight rod 601, controls the entire long push rod 6 to move horizontally, thereby controlling the corresponding stabilizing roller 2 to move horizontally.

[0028] When the long push rod 6 moves, the two long push rods 6 move synchronously in opposite directions. In this way, the two stabilizing rollers 2 can be controlled to move closer or further apart. Since the rotational motion is converted into linear motion in this process, the small distance between the stabilizing rollers 2 can be adjusted. This allows the final distance between the two stabilizing rollers 2 to better meet the requirements of strip exiting the zinc pot, reduce vibration, and improve the final strip quality.

[0029] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
