Description

Technical Field

[0001] This utility model relates to the field of submerged roller technology, specifically a submerged roller that adapts to load changes. Background Technology

[0002] Submerged rolls are key equipment in the hot-dip galvanizing process. Located inside the zinc pot, their main function is to guide the strip steel into the molten zinc and complete the galvanizing process. Submerged rolls are usually designed as hollow rolls, and both their inner and outer surfaces are subjected to the force of the molten zinc. This helps to reduce the buoyancy of the submerged roll, but it also increases the calculation difficulty. Inside the zinc pot, the submerged rolls are subjected to high temperatures and corrosion from the molten zinc, so they need to be made of high-temperature resistant and corrosion-resistant materials.

[0003] An adaptive load-changing submerged roll is a specially designed submerged roll that can automatically adjust its working state according to changes in load to maintain the stability and efficiency of the galvanizing process.

[0004] When the submerged roll guides the strip through the galvanizing process, its guiding speed needs to be matched with parameters such as the strip tension, speed, and tension to ensure the uniformity of the galvanizing process and the quality of the strip surface. If the guiding speed of the submerged roll is too fast or too slow, it will cause wear on the strip surface. Therefore, an adaptive load-varying submerged roll is proposed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an adaptive submerged roll that adapts to load changes, in order to solve the problem that if the guiding speed of the submerged roll is too fast or too slow, it will cause wear on the surface of the strip.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] An adaptive load-changing submersible roller includes a drive motor 1 and an adaptive component 2. The drive motor 1 has an adaptive component 2 fixedly connected to the end of its main shaft. A submersible roller assembly 3 is rotatably connected to the inner side of the adaptive component 2. The adaptive component 2 includes a cylindrical column 21 with a spring groove 22 and a retaining groove 23 on its inner side. A shaft hole 25 is provided on the inner side of the cylindrical column 21 near the submersible roller assembly 3. A bearing 24 is fixedly connected to the inner side of the shaft hole 25 in the cylindrical column 21. The submersible roller assembly 3 includes a rotating roller 31 with a submersible roller shaft column 32 fixedly connected to one side. A submersible roller body column 33 is fixedly connected to the outer side of the submersible roller shaft column 32. A spring-loaded spring 34 is fixedly connected to the outer side of the submersible roller body column 33. A retaining plate 35 is fixedly connected to one side of the spring-loaded spring 34.

[0027] As a further implementation of this solution, the main shaft of the drive motor 1 is fixedly connected to one side of the cylinder 21. The center of the main shaft of the drive motor 1 and the center of the cylinder 21 are on the same horizontal line, which helps to reduce energy loss during transmission and improve transmission efficiency. At the same time, it can also ensure that the connection between the drive motor 1 and the cylinder 21 is more secure and reduce the risk of failure due to unstable connection.

[0028] As a further implementation of this solution, the column 21 is a hollow cylinder, the spring groove 22 is a two-section cylinder, and the end of the column 21 near the roller 31 is a through-hole opening, which not only reduces the weight of the device and the material cost, but also provides enough space to accommodate other components.

[0029] As a further implementation of this scheme, the spring groove 22 is connected to the shaft hole 25, and the number of bearings 24 is set in two sets, with two bearings in each set. The inner side of the bearing 24 is fixedly connected to the outer side of the roller 31. This design helps to distribute the load, reduce the wear of individual components, and thus extend the service life of the entire device.

[0030] As a further implementation of this solution, the slot 23 is trapezoidal in shape. The slot 23 is connected to the spring groove 22 in the column 21. The inner side of the slot 23 engages with the outer side of the plate 35, ensuring the tightness and reliability of the engagement. At the same time, the engagement between the plate 35 and the slot 23 facilitates the rotation of the roller 31 when the column 21 rotates.

[0031] As a further implementation of this solution, two rotating rollers 31 are fixed at both the front and rear ends of the submerged roller shaft column 32. The rotating rollers 31 are cylindrical in shape. A spring 34 is embedded in the spring groove 22 opened in the column cylinder 21 and is sleeved on the outside of the rotating roller 31. The clamping plate 35 is trapezoidal in shape. There are two springs 34 and two clamping plates 35. The rotation speed of the submerged roller body column 33 can be automatically adjusted to ensure that the submerged roller body column 33 maintains a uniform speed to guide the strip steel. At the same time, it prevents friction between the submerged roller body column 33 and the strip steel due to excessive speed of the column cylinder 21, thus preventing damage to the surface of the strip steel.

[0032] Workflow: During the galvanizing process guided by the submerged roller, to prevent friction between the submerged roller and the strip due to excessively fast or slow speeds, one side of the strip is in contact with the outer side of the submerged roller body column 33. The submerged roller body column 33 guides the strip for galvanizing. The drive motor 1 is started, driving the column cylinder 21 to rotate. The rotation of the column cylinder 21, through the engaging plate 35, drives the spring 34 to rotate. At this time, the spring 34 is in an elastically contracted state. As the spring 34 reaches its elastic limit, it drives the rotating roller 31 to rotate. The rotation of the rotating roller 31 drives the submerged roller shaft column 32 and the submerged roller body column 33 to rotate. Due to friction, the submerged roller body column 33 guides the strip. When the drive motor 1 drives the column cylinder 21 to rotate too fast, the column cylinder 21 will rapidly pull the spring 34 due to the rotational speed. When the pulling force is greater than the frictional force between the clamping plate 35 and the clamping groove 23, the clamping plate 35 will disengage from the inside of the clamping groove 23 and engage with another clamping groove 23 in the next step. This prevents the submerged roller body column 33 from rubbing against the strip due to excessive rotation speed. When the rotation speed of the column 21 is slow, the spring spring 34 will loosen elastically. Under the action of the torque of the spring spring 34, the roller 31 will rotate rapidly, thereby causing the submerged roller body column 33 to rotate rapidly. This ensures that the rotation speed of the submerged roller body column 33 is consistent with the speed of the strip. The device can automatically adjust the rotation speed of the submerged roller body column 33 to ensure that the submerged roller body column 33 maintains a uniform speed guidance for the strip, while preventing friction between the submerged roller body column 33 and the strip due to excessive speed of the column 21, thus preventing damage to the surface of the strip.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
