Description
Technical Field
[0001] This utility model relates to the field of support roller frame technology, and specifically to a thermal roller support roller frame with a reinforced composite structure. Background Technology
[0002] In various equipment that uses hot rollers, such as production lines in industries like papermaking, printing and dyeing, and plastics processing, the hot rollers need to rotate continuously and stably. The support roller frame with a reinforced composite structure provides reliable support for the hot rollers, ensuring that they remain stable during high-speed rotation and long-term operation, and preventing problems such as shaking or deviation that affect production quality.
[0003] The existing technology has the following problems: The existing equipment cannot install or disassemble hot rollers of any size and length during use, and is not compatible with hot rollers of different lengths. This means that the equipment can only match hot rollers of specific specifications. If it is necessary to change hot rollers of different sizes during production, it is necessary to purchase or customize special support roller frames. It cannot flexibly respond to changes in production needs. In addition, the existing equipment cannot effectively reduce vibration. Vibration reduction failure will cause the hot roller to vibrate violently during operation, resulting in uneven contact pressure between the hot roller and the processed material. This can easily lead to problems such as local overheating of the material, indentation, and thickness deviation. Even slight vibrations can cause the product to fail to meet the dimensional accuracy or surface quality standards, directly increasing the scrap rate. Utility Model Content

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific implementation methods.
[0016] like Figure 1 As shown, this utility model provides a reinforced composite structure for a hot roller support frame, including a base 1. Two shock-absorbing mechanisms 12 are arranged on the upper side of the base 1. A fixed frame 2 is arranged at the upper end of each shock-absorbing mechanism 12. Two movable frames 3 are slidably connected to the upper side of the fixed frame 2. A support 4 is fixedly connected to the upper side of each movable frame 3. A cylinder 5 is fixedly connected through the upper side of the support 4. A lifting plate 6 is fixedly connected to the output end of the cylinder 5. A rotating roller 9 is arranged on the opposite side of the two movable frames 3. The base 1 provides stable bottom support for the entire device. The shock-absorbing mechanism 12 above it connects the base 1 and the fixed frame 2, which can initially dampen the shock. The vibration during operation of the punching device is supported by two movable frames 3 slidably connected on the fixed frame 2, which are the core carriers supporting the hot roller. The bracket 4 on the upper side of the movable frame 3 fixes the cylinder 5. When it is necessary to support the rotating roller 9, the cylinder 5 is activated. The output end of the cylinder 5 will drive the lifting plate 6 to move up and down. The clamping plate 7 below the lifting plate 6 moves synchronously until the roller 11 connected to the opening 8 on the clamping plate 7 through the rotating rod 10 contacts the outer wall of the rotating roller 9. At this time, the roller 11 can rotate with the rotating roller 9, which not only achieves vertical limit support for the rotating roller 9, but also avoids the normal rotation of the rotating roller 9 due to excessive friction.
[0017] like Figure 2-3As shown, this utility model provides a technical solution: Preferably, a clamping plate 7 is fixedly connected to the lower side of the lifting plate 6. Two openings 8 are opened through the upper side of the clamping plate 7. Two rotating rods 10 are rotatably connected to the inner surface of the openings 8. Rollers 11 are fixedly connected to the outer wall of the rotating rods 10. The outer wall of the rollers 11 is movably connected to the rotating rollers 9. Two threaded rods 14 are provided on the upper side of the fixing frame 2. Two pairs of support plates 18 are fixedly connected to the upper side of the fixing frame 2. The outer wall of the threaded rods 14 is rotatably connected to the support plates 18. A motor 13 is fixedly connected to the rear end of the right threaded rod 14. A drive wheel 15 is fixedly connected to the front end of the right threaded rod 14. A synchronous belt 17 is drivenly connected to the outer wall of the drive wheel 15. A driven wheel 16 is fixedly connected to the front end of the left threaded rod 14. The inner surface of the synchronous belt 17 is... The moving frame 3 is movably connected to the driven wheel 16. When it is necessary to adjust the distance between the two moving frames 3 to match the length of the rotating roller 9, the motor 13 at the right end is started. The output end of the motor 13 drives the threaded rod 14 at the right end to rotate. At the same time, the drive wheel 15 at the front end of the threaded rod 14 at the right end drives the driven wheel 16 at the front end of the threaded rod 14 at the left end to rotate synchronously through the synchronous belt 17, so that the two threaded rods 14 rotate at the same speed and in the same direction. Since the moving frame 3 is threadedly connected to the threaded rod 14 and the moving frame 3 is slidably connected to the fixed frame 2, the rotation of the threaded rod 14 will be converted into the horizontal sliding of the moving frame 3 along the fixed frame 2. By controlling the forward and reverse rotation and the running time of the motor 13, the distance between the two moving frames 3 can be precisely adjusted, thereby accommodating rotating rollers 9 of different lengths and facilitating the installation and disassembly of the rotating roller 9.
[0018] like Figure 4-5As shown, this utility model provides a technical solution: Preferably, the shock absorption mechanism 12 includes a fixed column 121, the lower side of which is fixedly connected to the base 1, a connecting column 19 is slidably connected through the upper side of the fixed column 121, the upper end of the connecting column 19 is fixedly connected to the fixed frame 2, and a movable plate 128 is fixedly connected to the lower end of the connecting column 19. Two limiting rods 125 are fixedly connected to the lower side of the movable plate 128. Two limiting grooves 1210 are opened on the lower side of the inner surface of the fixed column 121. A limiting block 129 is slidably connected to the inner surface of the fixed column 121. A movable block 122 is fixedly connected to the upper side of the limiting block 129. A slanted groove 123 is opened through the right side of the movable block 122. The inner surface of the slanted groove 123 is slidably connected to the limiting rod 125. Multiple guide posts 126 are fixedly connected to the lower side of the inner surface of the fixed column 121. The outer wall of the guide post 126 is slidably connected to the movable plate 128. Two springs 127 are sleeved on the outer wall of the guide post 126. A damping shock absorption device 1 is provided on the opposite surface of the two movable blocks 122. 24. The shock absorption mechanism 12 achieves effective shock absorption through the synergistic effect of the mechanical structure. Its core is to convert the vertical vibration generated during the operation of the device into a lateral buffer force. When the fixed frame 2 is subjected to a downward force transmitted by vibration, the fixed frame 2 will push the connecting column 19 to slide downward along the fixed column 121. The movable plate 128 at the lower end of the connecting column 19 will move downward synchronously. The limiting rod 125 on the lower side of the movable plate 128 will slide in the inclined groove 123 as the movable plate 128 moves downward, pushing the two movable plates 128 to slide downward. Block 122 moves in the opposite direction along the limiting groove 1210 in the fixed column 121. During this process, the movable block 122 will squeeze the damping and shock absorption device 124 on the opposite side. At the same time, when the movable plate 128 slides along the guide column 126, it will compress the spring 127 on the outer wall of the guide column 126. The damping force of the damping and shock absorption device 124 and the elastic force of the spring 127 work together to consume vibration energy, thereby effectively weakening the vibration transmitted to the base 1, preventing the rotating roller 9 from shaking or shifting due to vibration, and ensuring the smooth operation of the rotating roller 9.
[0019] The working principle of the hot roller support frame of this reinforced composite structure will be explained in detail below.
[0020] like Figure 1-5As shown, when it is necessary to adjust the distance between the two movable frames 3 to match the length of the rotating roller 9, the motor 13 on the right end is started. The output end of the motor 13 drives the threaded rod 14 on the right end to rotate. At the same time, the drive wheel 15 at the front end of the threaded rod 14 on the right end drives the driven wheel 16 at the front end of the threaded rod 14 on the left end to rotate synchronously through the synchronous belt 17, so that the two threaded rods 14 rotate at the same speed and in the same direction. Since the movable frame 3 is threadedly connected to the threaded rod 14 and the movable frame 3 is slidably connected to the fixed frame 2, the rotation of the threaded rod 14 will be converted into the horizontal sliding of the movable frame 3 along the fixed frame 2. By controlling the forward and reverse rotation and the running time of the motor 13, the distance between the two movable frames 3 can be precisely adjusted, thereby accommodating rotating rollers 9 of different lengths and facilitating the installation and disassembly of the rotating roller 9. The shock absorption mechanism 12 achieves effective shock absorption through the synergistic effect of the mechanical structure. Its core is to convert the vertical vibration generated during the operation of the device into Lateral buffering force: When the fixed frame 2 is subjected to vibration and downward force, the fixed frame 2 will push the connecting column 19 to slide downward along the fixed column 121. The movable plate 128 at the lower end of the connecting column 19 will move downward synchronously. The limiting rod 125 on the lower side of the movable plate 128 will slide in the inclined groove 123 as the movable plate 128 moves downward, pushing the two movable blocks 122 to move in opposite directions along the limiting groove 1210 in the fixed column 121. During this process, the movable block 122 will squeeze the damping and shock absorption device 124 on the opposite side. At the same time, when the movable plate 128 slides along the guide column 126, it will compress the spring 127 on the outer wall of the guide column 126. The damping force of the damping and shock absorption device 124 and the elastic force of the spring 127 work together to consume vibration energy, thereby effectively weakening the vibration transmitted to the base 1, preventing the roller 9 from shaking or shifting due to vibration, and ensuring the smooth operation of the roller 9.
