Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rollers, in particular to a novel coaxial roller. Background Art
[0002] At present, the traditional rollers or guide rollers of continuous heat treatment units for aluminum and steel strips mainly adopt single roller technology, such as Figure 3-4 As shown in the figure, the roller is rotated on the fixed axis by using the built-in bearing, thus supporting and guiding the strip.
[0003] However, conventional rollers with built-in bearings have a simple structure and are easy to replace. However, due to their small size, they cannot withstand heavy loads. If the load needs to be increased, the roller size must be increased. This not only increases costs but also makes them unsuitable for applications where space is limited. Furthermore, rollers should not be designed to be too narrow or long, as they can easily bend under the weight of the rollers and the belt, thus affecting the equipment's accuracy and service life. Utility Model Content
[0004] The purpose of the utility model is to provide a novel coaxial roller to solve the problems raised in the above background technology.
[0005] The technical solutions adopted in this utility model are as follows:
[0006] A novel coaxial roller comprises a support beam, wherein a plurality of support frames are sequentially arranged on the top of the support beam from left to right, roller shafts are interspersed between the support frames, and split rollers are arranged between adjacent support frames.
[0007] Preferably, the roller shaft is arranged along the central axis of the plurality of split rollers, and both ends of the split rollers are rotatably connected to the roller shaft through bearings.
[0008] Preferably, the plurality of support frames are distributed in a linear array.
[0009] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0010] In the utility model, support is added to the main shaft of the roller, and the previous support at both ends of the main shaft is changed to multi-point support. The roller is divided into sections, and each section of the roller is installed with a separate bearing. Support points are designed between the rollers, and support beams are designed below the support points, which increases the support strength of the shaft. Under the same load, the bending moment borne by the support roller is greatly reduced, and the diameter of the support roller can be designed to be very small. Due to the coaxial design, the running accuracy will not be affected at all, and the strength of the roller is also greatly enhanced. Compared with traditional rollers, the diameter is smaller and the requirement for installation width is lower. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0017] Example:
[0018] A new type of coaxial roller, such as Figure 1-4 As shown, it includes a support beam 1, and a plurality of support frames 2 are sequentially arranged on the top of the support beam 1 from left to right. Roller shafts 2 are interspersed between the plurality of support frames 2, and split rollers 4 are arranged between adjacent support frames 2.
[0019] In a possible embodiment, the roller shaft 2 is arranged along the central axis of the plurality of split rollers 4 , and both ends of the split rollers 4 are rotatably connected to the roller shaft 2 through bearings 5 .
[0020] In a possible embodiment, a plurality of support frames 2 are distributed in a linear array.
[0021] Furthermore, the new coaxial rollers are primarily used in areas of continuous strip production lines, such as steel and aluminum alloys, where space is limited and installation of traditional passive rollers is inconvenient. The number of roller sections can be designed based on the width of the assembly line, the space available for the unit, and the load.
[0022] In a possible implementation, different structures may be selected for the lower support beam according to objective conditions such as on-site load requirements, as long as the support effect is achieved.
[0023] Furthermore, the new coaxial roller is not only used as a passive roller, but can also be used in related working occasions such as pressure rollers, steering rollers, and guide rollers.
[0024] Furthermore, several split rollers 4 correspond to the same roller shaft 3 .
[0025] Working principle, see Figure 4Increasing the length of traditional rollers inevitably increases their diameter, which in turn increases their weight and size. This is particularly problematic for some mills designed for wider strips. For example, an air cushion furnace mill producing aluminum alloys requires rollers approximately 3 meters long. To effectively support the strip, the rollers must have a diameter of at least 110 mm. However, certain specific mill sections cannot be installed if their width is less than 110 mm. Therefore, a roller that can withstand heavy loads while being narrow enough to meet production needs was needed.
[0026] Reference Figure 1 The new coaxial rollers feature additional support on the main shaft, replacing the previous two-end support with multi-point support. The rollers are segmented, each with its own bearing. Support points are placed between the rollers, with support beams positioned below them, increasing shaft support strength. Under the same load, the bending moment on the rollers is significantly reduced, allowing for very small diameter designs. The coaxial design also minimizes operational accuracy.
[0027] Reference Figure 2-3 Because the roller is designed in sections and each section has additional bearings, the roller strength can be greatly enhanced. Compared with traditional rollers, the diameter is smaller and the installation width requirement is lower.
[0028] In summary:
[0029] The improved rollers are smaller and lighter, making them easier to install in narrow machine spaces. They are also less likely to bend under heavy loads.
[0030] New coaxial rollers are primarily used to replace traditional passive rollers in specialized applications. Because the rollers are segmented, the length and diameter of each section are significantly reduced. The lighter rollers are more easily dragged by the strip, significantly reducing friction between the strip and roller surface. This prevents scratches and improves the surface quality of the strip, especially strip material.
[0031] The improved roller is shorter and easier to process, resulting in lower costs. Even if damaged, it is cheaper to repair.
[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
