Description

Technical Field

[0001] This utility model belongs to the field of strip steel stabilization technology, and in particular relates to a strip steel stabilization threading device for a continuous hot-dip galvanizing production line. Background Technology

[0002] The strip stabilizing threading device is a key device installed at the entrance section of the hot-dip galvanizing production line. It is specifically designed to solve three major problems of strip deviation, shaking, and sagging during high-speed operation, ensuring that the strip enters the zinc pot with a stable posture and precision. This device directly determines the surface quality of the galvanized sheet and the speed of the production line. It is one of the key areas for breakthroughs in the core equipment technology of hot-dip galvanizing and has been applied to modern continuous hot-dip galvanizing production lines.

[0003] Based on the above, the inventors have discovered the following shortcomings in existing strip stabilizing threading devices: 1. The stabilizing roller is a single piece, which makes it difficult to disassemble and replace after pits and damage appear on the surface of the stabilizing roller. It is not convenient to make the stabilizing roller a modular type so that it can be disassembled and replaced. 2. The strip steel is prone to deviating along the axis of the stabilizing roller during the conveying process, which affects the stability of the strip steel. It is inconvenient to install double stabilization measures on the device to ensure the stable conveying effect of the strip steel. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a strip stabilizing threading device for a continuous hot-dip galvanizing production line. This solves the problems of existing integrated stabilizing rollers, which are difficult to replace after surface damage such as pits, making it inconvenient to design them as modular units for easy disassembly and replacement; and the strip's tendency to deviate along the stabilizing roller axis during transport, affecting its stability, making it inconvenient to add dual stabilizing measures to the device to ensure stable strip transport.

[0005] The purpose and effectiveness of this utility model for a strip stabilizing threading device in a continuous hot-dip galvanizing production line are achieved by the following specific technical means: A strip stabilizing threading device for a continuous hot-dip galvanizing production line includes a device body; the device body is provided with a stabilizing roller main shaft, both ends of which are provided with through insertion holes, and both ends of the stabilizing roller main shaft are provided with fixing columns. The left end face of the fixing column on the left side of the stabilizing roller main shaft is provided with a regular hexagonal prism. A semi-cylinder stabilizing roller is provided in front of the stabilizing roller main shaft. Both ends of the outer circumference of the semi-cylinder stabilizing roller are provided with stepped holes that penetrate from front to back. A combined roller semi-cylinder is installed behind the semi-cylinder stabilizing roller by bolts. Both ends of the combined roller semi-cylinder are provided with threaded holes that penetrate from front to back.

[0006] Furthermore, a strip steel auxiliary roller is installed between the fixing holes of the lifting support frame via a fixing shaft. The strip steel auxiliary roller has a rotating hole that runs through it from left to right at its center, and a wear-resistant layer is provided on the surface of the rotating hole.

[0007] Furthermore, a lifting support frame is inserted between the guide holes of the stabilizing support rod. The lifting support frame is a U-shaped rod structure with the opening facing downwards. The lower end of the upright of the lifting support frame has a fixing hole that runs through the left and right sides. The lower outer circumference of the upright of the lifting support frame is threaded. The upper outer circumference of the upright of the lifting support frame is fitted with a spring. The lower outer circumference of the upright of the lifting support frame is fitted with a nut through the thread.

[0008] Furthermore, a steel strip limiting plate is installed on the bearing ring groove of the rotary adjusting cylinder via a bearing. The upper end of the steel strip limiting plate is provided with a semi-circular head with left and right through holes, and the bottom end face of the steel strip limiting plate is provided with an arc groove.

[0009] Furthermore, the outer circumferences of both the left and right sides of the stabilizing support rod are threaded with rotating adjustment cylinders. The inner circumference of the rotating adjustment cylinder is threaded, the outer circumference of the outer end of the rotating adjustment cylinder is provided with a regular hexagonal structure, and the outer circumference of the inner end of the rotating adjustment cylinder is provided with a bearing ring groove.

[0010] Furthermore, a stabilizing support rod is installed between the insertion holes of the assembled support plate by bolts. The stabilizing support rod has a through-hole fixing hole at both ends, threads on the outer circumference of both the left and right sides, and a through-hole guide hole on both the left and right sides in the middle of the stabilizing support rod.

[0011] Furthermore, an assembly bearing plate is mounted on the fixed column of the stabilizing roller main shaft via bearings. The lower end of the assembly bearing plate has a bearing hole that extends through the left and right sides, the upper end of the assembly bearing plate has an insertion hole that extends through the left and right sides, and the top end face of the assembly bearing plate has a threaded blind hole in the middle.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The half-cylinder stabilizing roller and the combined roller half-cylinder are conveniently fastened to the outside of the stabilizing roller main shaft and locked with bolts. This facilitates the disassembly and replacement of the half-cylinder stabilizing roller and the combined roller half-cylinder, solving the problem that the stabilizing roller is a single piece, and the process of disassembling and replacing it is difficult after pits and damage appear on the surface of the stabilizing roller. It is also inconvenient to set the stabilizing roller as a combination so that the stabilizing roller can be disassembled and replaced.

[0013] It is convenient to limit the strip steel to prevent deviation by using the strip steel limit plate, and convenient to press the strip steel to prevent it from tilting by using the strip steel auxiliary roller. This achieves double stability of the strip steel and solves the problem that the strip steel is prone to deviation along the axis of the stabilizing roller during the conveying process, which affects the stability of the strip steel and makes it inconvenient to install double stabilization measures on the device to ensure the stable conveying effect of the strip steel.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0022] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown: This utility model provides a strip stabilizing threading device for a continuous hot-dip galvanizing production line, comprising a device body 1; the device body 1 is provided with a stabilizing roller main shaft 2, which facilitates the bearing of a semi-cylinder stabilizing roller 3 and a combined roller semi-cylinder 4.

Both ends of the stabilizing roller main shaft 2 are provided with fixing posts for easy assembly of the bearing plate 5 via bearings. The left end of the fixing post on the left side of the stabilizing roller main shaft 2 is provided with a regular hexagonal prism for easy docking and synchronous rotation with an external power device. A semi-cylinder stabilizing roller 3 is provided in front of the stabilizing roller main shaft 2, which can be combined with the combined roller semi-cylinder 4 to form a complete stabilizing roller. Both ends of the outer circumference of the semi-cylinder stabilizing roller 3 are provided with stepped holes for easy bolt insertion and concealment. A combined roller semi-cylinder 4 is bolted to the rear of the semi-cylinder stabilizing roller 3, which can be combined with the combined roller semi-cylinder 4 to form a complete stabilizing roller. Both ends of the combined roller semi-cylinder 4 are provided with... The assembly bearing plate 5 is provided with threaded holes that pass through the front and rear, facilitating the assembly of the half-cylinder stabilizing roller 3 by bolts. The mounting column of the stabilizing roller main shaft 2 is fitted with an assembly bearing plate 5 via bearings, facilitating the support of various components. The lower end of the assembly bearing plate 5 has bearing holes that pass through the left and right sides, facilitating the installation of the stabilizing roller main shaft 2 via bearings. The upper end of the assembly bearing plate 5 has insertion holes that pass through the left and right sides, facilitating the insertion and installation of the stabilizing bearing rod 6. A threaded blind hole is provided in the middle of the top end face of the assembly bearing plate 5, facilitating the fixing of the stabilizing bearing rod 6 by bolts. The stabilizing bearing rod 6 is installed between the insertion holes of the assembly bearing plate 5 via bolts, facilitating the support of the rotating adjusting cylinder 7 and the lifting bearing frame 9. Both ends of the stabilizing bearing rod 6 have vertically penetrating fixing holes, facilitating the fixing of the stabilizing bearing rod 6 by bolts. Threads are provided on the outer circumference of both sides of the stabilizing bearing rod 6, facilitating the installation of the rotating adjusting cylinder 7 via threads. The middle of the stabilizing bearing rod 6 has vertically penetrating guide holes on both sides, facilitating the insertion and installation of the lifting bearing frame 9.

[0023] The stabilizing support rod 6 has rotating adjusting cylinders 7 threadedly installed on the outer circumference of both sides, facilitating adjustment by threaded engagement. The inner circumference of the rotating adjusting cylinder 7 is also threaded for easy installation. The outer circumference of the rotating adjusting cylinder 7 has a regular hexagonal structure for easy rotation using tools. The outer circumference of the inner end of the rotating adjusting cylinder 7 has a bearing ring groove for easy installation of the strip steel limiting plate 8 via bearings. The strip steel limiting plate 8 is mounted on the bearing ring groove of the rotating adjusting cylinder 7 via bearings, allowing the rotating adjusting cylinder 7 to move the strip steel limiting plate 8. The upper end of the strip steel limiting plate 8 has a semi-circular head with left and right through holes for easy installation of the rotating adjusting cylinder 7 via bearings. The bottom end face of the strip steel limiting plate 8 has an arc groove for easy engagement with the outer circumference of the half-cylinder stabilizing roller 3 and the combined half-cylinder roller 4. A lifting support frame 9 is inserted between the guide holes of the stabilizing support rod 6 for easy... The lifting support frame 9 moves up and down. The lifting support frame 9 has a U-shaped rod structure with an opening facing downwards, facilitating the support of the strip auxiliary roller 10. The lower end of the upright of the lifting support frame 9 has a through-hole for easy installation of the strip auxiliary roller 10 via a fixed shaft. The lower outer circumference of the upright of the lifting support frame 9 has threads for easy installation of a nut. A spring is fitted around the upper outer circumference of the upright of the lifting support frame 9, allowing the strip auxiliary roller 10 to press downwards against the strip. A nut is threaded onto the lower outer circumference of the upright of the lifting support frame 9 to limit the lower end of the spring. The strip auxiliary roller 10 is installed between the fixed holes of the lifting support frame 9 via a fixed shaft, facilitating rotation and contact with the strip. The center of the strip auxiliary roller 10 has a through-hole for easy rotation. The surface of the rotation hole of the strip auxiliary roller 10 is provided with a wear-resistant layer to increase its service life.

[0024] The specific usage and function of this embodiment are as follows: In this utility model, such as Figure 3 As shown, the semi-drum stabilizing roller 3 and the combined semi-drum 4 are bolted to the outside of the stabilizing roller main shaft 2. This method solves the problem that the replacement process is difficult when the stabilizing roller is a single piece and its surface is damaged by pits. Thus, the stabilizing roller main shaft 2 drives the semi-drum stabilizing roller 3 and the combined semi-drum 4 to rotate, and simultaneously, the outer circumference of the semi-drum stabilizing roller 3 and the combined semi-drum 4 contacts the strip steel, thereby realizing the conveying of the strip steel. Figure 1As shown, the strip limiting plates 8 are located on the left and right sides of the strip, thereby limiting the strip and preventing it from shifting or deviating along the axis of the stabilizing roller main shaft 2, ensuring the stability of the strip. This method solves the problem that the strip is prone to deviating along the axis of the stabilizing roller during conveying, affecting the stability of the strip. At the same time, the strip auxiliary roller 10 is pressed against the top of the strip by a spring, thereby preventing the strip from losing contact with the outer circumference of the half-cylinder stabilizing roller 3 and the combined half-cylinder roller 4 and tilting up, thus enhancing the stability of the strip conveying and limiting the strip. The positioning plate 8 works in conjunction with the strip auxiliary roller 10 to achieve a dual stabilizing effect. When the strip limiting plate 8 is adjusted according to the strip width, the rotating adjusting cylinder 7 is threadedly engaged with the stabilizing bearing rod 6 by rotating the tool. This causes the rotating adjusting cylinder 7 to move to the left or right through the threaded engagement. The rotating adjusting cylinder 7 then drives the strip limiting plate 8 to move synchronously to the left or right along the outer circumference of the half-cylinder stabilizing roller 3 and the combined half-cylinder roller 4 through the bearing. This makes the spacing between the strip limiting plates 8 the same as the strip width, so that the strip limiting plate 8 can be used for strips of different widths.

[0025] Example 2: Unlike Example 1, the hexagonal structure of the rotary adjustment cylinder 7 can also be set as a regular heptagonal structure. This makes the rotary adjustment cylinder 7 require a special tool that works with the regular heptagonal structure to rotate, thus preventing non-staff members from rotating and adjusting the rotary adjustment cylinder 7.

[0026] Example 3: The difference from Example 1 is that the outer circumferential surface of the strip auxiliary roller 10 can also be set as a frosted surface, thereby increasing the friction between the outer circumferential surface of the strip auxiliary roller 10 and the strip, and preventing the strip auxiliary roller 10 from rotating and jamming.
