Description

Technical Field

[0001] This application relates to the field of leveling machine equipment technology, and in particular to a leveling machine roller disassembly and assembly structure that is easy to maintain. Background Technology

[0002] In the daily use of a leveling machine, the rollers, as key components that directly contact and smooth the materials, are prone to replacement or maintenance due to wear and deformation. Currently, most leveling machine roller installation structures use a fixed installation method, such as bolting the roller mounting base to the machine frame. When this method requires roller disassembly, operators need to use specialized tools to unscrew numerous bolts one by one, a cumbersome and time-consuming process. Moreover, the difficulty of unscrewing bolts is further increased when operating space is limited. Furthermore, frequent bolt disassembly and installation can easily damage the threads, affecting the overall stability and service life of the equipment. According to incomplete statistics, replacing a roller using the traditional fixed installation method takes an average of [X] hours, significantly impacting production efficiency and increasing operating costs. Therefore, developing a leveling machine roller disassembly and assembly structure that is easy to maintain is of significant practical importance. Utility Model Content

[0003] The purpose of this utility model is to provide a convenient maintenance structure for the disassembly and assembly of rollers in a straightening machine, so as to solve the problem that the existing roller installation structure of a straightening machine is inconvenient to disassemble and install, which affects production efficiency and equipment service life.

[0004] This application provides a maintenance-friendly roller assembly and disassembly structure for a leveling machine, which adopts the following technical solution: it includes a base and two roller assemblies, the two roller assemblies are arranged opposite to each other on the base, each roller assembly includes a mounting seat and a roller body, the roller body is disposed on the mounting seat, the mounting seat is slidably disposed on the base, and the base is provided with a sliding drive mechanism for driving the mounting seat to slide.

[0005] Optionally, the sliding drive mechanism includes a slide groove disposed on the base and a slider disposed on the mounting base and adapted to the slide groove. The base is also provided with a bidirectional screw for driving the slider to slide along the slide groove. The two sides of the bidirectional screw are respectively threaded to the slider, and a rotating handle is provided at one end of the bidirectional screw.

[0006] Optionally, the mounting base is provided with a limiting mechanism that can limit the roller body. The limiting mechanism includes a limiting groove, which is opened on both sides of the roller body. The mounting base is provided with a plurality of support components that can support the roller body. The mounting base is also provided with a movable frame that can move along the axial direction of the roller body. When the movable frame moves, it can drive the support components to move.

[0014] Reference Figure 1 One embodiment shown is a maintenance-friendly roller assembly / disassembly structure for a leveling machine, comprising a base 1 and two roller assemblies 2 mounted opposite each other on the base 1. Each roller assembly 2 includes a mounting base 3 and a roller body 4. The roller body 4 is connected by a suitable method. The bottom of the mounting base 3 is equipped with a slider structure that cooperates with a sliding track. The mounting base 3 slides on the sliding track of the base 1 via the slider 7. A sliding drive mechanism 5 is also provided on the base 1 to drive the mounting base 3 to slide.

[0015] The implementation principle of the above embodiment is as follows: the distance between the two roller assemblies 2 can be adjusted through the sliding drive mechanism 5, facilitating subsequent maintenance operations such as installation and disassembly of the roller body 4. Compared with the traditional fixed installation method, this structural design can quickly adjust the spacing between the roller assemblies 2, improving the convenience of equipment maintenance and reducing maintenance time.

[0016] Reference Figure 1 , Figure 2One embodiment shown is as follows: The sliding drive mechanism 5 specifically consists of a groove 6 on the upper surface of the base 1 and a slider 7 at the bottom of the mounting base 3 that is adapted to the groove 6. The groove 6 is opened along the length of the base 1, and its shape and size are precisely matched with the slider 7 to ensure that the slider 7 can slide smoothly within the groove 6. The slider 7 at the bottom of the mounting base 3 is embedded in the groove 6 of the base 1. The slider 7 and the mounting base 3 are connected by welding or bolt fastening to ensure that the two form a stable whole, so that the mounting base 3 can move with the slider 7. A bidirectional screw 8 is also provided on the base 1. The bidirectional screw 8 is located between the two grooves 6 and is arranged parallel to the grooves 6. The two ends of the bidirectional screw 8 are respectively mounted on the base 1 through bearing seats to ensure that the bidirectional screw 8 can rotate smoothly. The two sides of the bidirectional screw 8 are respectively machined with threads of opposite directions, and the two sliders 7 are respectively threadedly connected to the threaded sections on both sides of the bidirectional screw 8. One end of the bidirectional screw 8 extends out of the base 1, and a rotating handle 9 is provided at this end. The rotating handle 9 is fixed to the bidirectional screw 8 by means of key connection or other means to ensure that the rotating handle 9 can effectively drive the bidirectional screw 8 to rotate.

[0017] The implementation principle of the above embodiment is as follows: The operator rotates the rotating handle 9 at one end of the bidirectional screw 8, which drives the bidirectional screw 8 to rotate. Since the threads on both sides of the bidirectional screw 8 have opposite directions and are threadedly connected to two sliders 7 respectively, according to the principle of thread transmission, when the bidirectional screw 8 rotates, the slider 7 threadedly connected to the left side of the bidirectional screw 8 will move to the left, and the slider 7 threadedly connected to the right side of the bidirectional screw 8 will move to the right, or vice versa. The movement of the sliders 7 causes the mounting base 3 to slide along the slide groove 6 on the base 1, thereby adjusting the distance between the two roller assemblies 2. This structural design, which drives the sliders 7 through the bidirectional screw 8, can achieve synchronous and reverse movement of the two roller assemblies 2. It is simple and convenient to operate, has a compact structure, occupies little space, and can accurately adjust the distance between the roller assemblies 2, meeting the needs of different material processing and roller maintenance for distance adjustment.

[0018] Reference Figure 4 , Figure 5One embodiment shown is as follows: A limiting mechanism 10 is provided on the mounting base 3 to limit the roller body 4. Annular limiting grooves 11 are respectively formed on both sides of the roller body 4, i.e., on both ends along the axial direction of the roller body 4. Multiple support components 12 are provided on the mounting base 3, evenly distributed along the length of the mounting base 3 and located below the roller body 4, for supporting the roller body 4. A movable frame 13 is provided above the mounting base 3, slidably connected to the mounting base 3 via a guide rail. The guide rail is arranged on the mounting base 3 along the axial direction of the roller body 4. A slider 7 cooperating with the guide rail is provided at the bottom of the movable frame 13, allowing the movable frame 13 to slide along the axial direction of the roller body 4 on the mounting base 3. Each support component 12 is connected to the movable frame 13. In this embodiment, the support component 12 and the movable frame 13 are connected by a connecting rod. One end of the connecting rod is hinged to the movable frame 13 and the other end is hinged to the support component 12. In this way, when the movable frame 13 moves, it can drive the support component 12 to move through the connecting rod.

[0019] The implementation principle of the above embodiment is as follows: When it is necessary to limit and support the roller body 4, the moving frame 13 is driven to move along the axial direction of the roller body 4. When the moving frame 13 moves, it drives the support assembly 12 to move through the connecting rod. During the movement, the support assembly 12 gradually approaches the roller body 4, and finally makes the support part of the support assembly 12 cooperate with the limiting grooves 11 on both sides of the roller body 4 to support and limit the roller body 4, ensuring the stability of the roller body 4 during operation. When it is necessary to disassemble the roller body 4, the moving frame 13 is driven in the opposite direction to disengage the support assembly 12 from the limiting grooves 11 of the roller body 4, making it easy to remove the roller body 4 from the mounting base 3. This limiting mechanism 10 can effectively limit and support the roller body 4, improve the working accuracy and stability of the equipment, and also facilitate the disassembly and maintenance of the roller body 4.

[0020] Reference Figure 5One embodiment shown is as follows: Each support assembly 12 includes a wedge block 14, which is located in a guide groove on the mounting base 3 that is aligned with the radial direction of the roller body 4, allowing the wedge block 14 to slide within the guide groove along the radial direction of the roller body 4. On the movable frame 13, a wedge rod 15 is provided corresponding to the position of each support assembly 12, and the wedge rod 15 is fixed to the movable frame 13 perpendicular to its moving direction. A compression spring 16 is provided between the wedge block 14 and the mounting base 3. One end of the compression spring 16 is fixedly connected to the mounting base 3 (e.g., via a hook welded to the mounting base 3), and the other end is fixedly connected to the wedge block 14 (e.g., via a lug welded to the wedge block 14). When the compression spring 16 is in its natural state, the wedge block 14 is located within the guide groove near the center of the mounting base 3. The wedge rod 15 has a beveled surface that matches the beveled surface of the wedge block 14. When the moving frame 13 moves the wedge rod 15, the beveled surface of the wedge rod 15 can interact with the beveled surface of the wedge block 14. At the top of the wedge block 14, a support rod 17 is fixedly installed perpendicular to the beveled surface of the wedge block 14. The top of the support rod 17 has a movable groove 18, in which a ball 19 is embedded. The ball 19 can roll freely within the movable groove 18. When the support assembly 12 is working, the ball 19 is located in the limiting grooves 11 on both sides of the roller body 4.

[0021] The implementation principle of the above embodiment is as follows: When the moving frame 13 moves axially along the roller body 4 under the action of the driving device, the wedge rod 15 on the moving frame 13 moves accordingly. During the movement of the wedge rod 15, its inclined surface pushes the inclined surface of the wedge block 14 downward. Due to the force of the inclined surface of the wedge rod 15 and the elastic force of the compression spring 16, the wedge block 14 slides outward in the guide groove along the radial direction of the roller body 4, compressing the compression spring 16. As the wedge block 14 slides outward, the ball 19 on the support rod 17 gradually approaches the limiting grooves 11 on both sides of the roller body 4, and finally enters the limiting grooves 11 to support and limit the roller body 4. When it is necessary to release the limiting position of the roller body 4, the moving frame 13 moves in the reverse direction, the wedge rod 15 disengages from the wedge block 14, the compression spring 16 returns to its original state, pulling the wedge block 14 back to its initial position, and the ball 19 slides out of the limiting groove 11, facilitating the disassembly of the roller body 4. This structural design of the support assembly 12, utilizing the inclined surface cooperation of the wedge block 14 and the wedge rod 15, as well as the elastic action of the compression spring 16, can achieve stable support and limiting of the roller body 4, and can conveniently and quickly release the limiting position when needed. It is simple to operate and highly reliable.

[0022] Reference Figure 5One embodiment is shown where a threaded hole is machined on the mounting base 3 in a direction perpendicular to the axial direction of the roller body 4, and a threaded cylinder 20 is threadedly connected to this threaded hole. One end of the threaded cylinder 20 passes through the threaded hole of the mounting base 3, and the other end inside the mounting base 3 is rotatably connected to the movable frame 13 via a bearing, so that when the threaded cylinder 20 rotates, it can drive the movable frame 13 to move along the axial direction of the roller body 4, while the movable frame 13 does not rotate with the threaded cylinder 20. At the other end of the threaded cylinder 20 located outside the mounting base 3, a rotating handwheel 21 is fixedly provided. The rotating handwheel 21 is fixed to the threaded cylinder 20 by welding or keying, ensuring that the rotating handwheel 21 can effectively drive the threaded cylinder 20 to rotate.

[0023] The implementation principle of the above embodiment is as follows: The operator rotates the handwheel 21, which drives the threaded cylinder 20 to rotate. Since the threaded cylinder 20 is threadedly connected to the mounting base 3, according to the principle of threaded transmission, the threaded cylinder 20 will move along its own axis when rotating. Because the threaded cylinder 20 is rotatably connected to the moving frame 13, the movement of the threaded cylinder 20 will drive the moving frame 13 to move along the axial direction of the roller body 4. By controlling the rotation direction and number of rotations of the handwheel 21, the moving distance of the moving frame 13 can be precisely controlled, thereby accurately adjusting the positional relationship between the support assembly 12 and the roller body 4, achieving accurate positioning and support of the roller body 4, and conveniently releasing the positioning when needed, facilitating maintenance operations on the roller body 4. This structural design, which uses the threaded cylinder 20 and the handwheel 21 to drive the moving frame 13, is simple and intuitive to operate, enabling precise control of the position of the moving frame 13, improving the ease of operation and maintenance efficiency of the equipment.

[0024] The working principle of this device is as follows: When the distance between the two roller assemblies 2 needs to be adjusted, the rotating handle 9 of the bidirectional screw 8 is rotated. The bidirectional screw 8 rotates, and because the threads on both sides are in opposite directions and are threadedly connected to the slider 7, it drives the slider 7 to slide along the slide groove 6, thereby causing the mounting base 3 to slide to change the distance. When limiting and supporting the roller body 4, the rotating handwheel 21 of the threaded cylinder 20 is rotated. The rotation of the threaded cylinder 20 drives the moving frame 13 to move along the roller axis. The wedge rod 15 of the moving frame 13 pushes the wedge block 14 to slide radially and compress the compression spring 16, so that the ball 19 on the support rod 17 enters the limiting grooves 11 on both sides of the roller. When disassembling, the handwheel 21 is rotated in the opposite direction, the compression spring 16 returns to its original position and pulls back the wedge block 14, the ball 19 disengages from the limiting groove 11, and the distance is adjusted to remove the roller. The whole process realizes convenient disassembly and assembly and stable operation of the roller.

[0025] The working principle of this device has been explained through the above embodiments. These embodiments only illustrate several implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
