Description

Technical Field

[0001] The utility model is applied to the technical field of annealing and pickling of medium and thick stainless steel plates. More specifically, it relates to a transport roller device with a combined new rubber-coated structure used in the production line of annealing and pickling of medium and thick stainless steel plates. Background Art

[0002] In the past, the rubber sleeve of the rubber-coated roller was installed on the steel roller body without being limited at the ends. During use, the rubber sleeve expanded axially due to heat, further causing relative rotation between the rubber sleeve and the welded steel roller, resulting in the position deviation of the steel plate along the velocity direction and perpendicular to the velocity direction during transportation, affecting the position accuracy of the steel plate during transportation. Summary of the Utility Model

[0003] Aiming at the problems that the rubber sleeve of the past rubber-coated roller is prone to deviation during use and the rotation of the rubber sleeve and the steel roller is asynchronous after heating, the purpose of the utility model is to provide a new combined transport roller with a rubber-coated structure.

[0004] To achieve the above purpose, the combined transport roller with a new rubber-coated structure of the utility model at least includes a steel roller. Inner layer end rubber sleeves are sleeved at both ends of the steel roller, and a plurality of inner layer middle rubber sleeves are continuously arranged on the steel roller between the two end rubber sleeves.

[0005] Further, an outer layer end rubber sleeve is sleeved outside each inner layer end rubber sleeve.

[0006] Further, an outer layer middle rubber sleeve is sleeved outside each inner layer middle rubber sleeve.

[0007] Further, the width of the outer layer middle rubber sleeve is smaller than that of the inner layer middle rubber sleeve.

[0008] Further, the outer layer middle rubber sleeve is located at the middle position of the inner layer middle rubber sleeve.

[0009] Further, end retaining rings are installed at both ends of the steel roller through bolts, and the diameter of the end retaining rings is larger than that of the inner layer end rubber sleeves.

[0010] Further, the steel roller is a hollow roller barrel. End caps are arranged at both ends inside the roller barrel. The end retaining rings are installed on the end caps through bolts, and ventilation holes are arranged on the end caps and the corresponding end retaining rings.

[0011] Further, the end retaining rings are split end retaining rings.

[0012] Further, roller shafts are coaxially arranged at both ends of the steel roller; the two roller shafts are installed in bearing seats.

[0013] Furthermore, one of the two roller shafts is drivingly connected to a reduction motor through a coupling.

[0014] The combined end bushing and middle bushing of the present utility model have the characteristics of high positioning accuracy, not being prone to deviation during use, and good synchronous rotation of the combined bushing and the steel roller after heating. The split end retaining ring has the characteristics of being convenient for disassembly and assembly, not scratching the bearing mounting surface, not blocking the exhaust holes on the body of the welded steel roller, and effectively axially limiting the combined bushing. The above two structures are the main innovation points of the present utility model and have considerable economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0021] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0022] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, the meaning of "a plurality" is two or more.

[0023] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] Embodiment 1

[0025] As can be seen from the above Figures 1-4 It can be seen that the designed combined new type of transport roller with a rubber-coated structure in this embodiment includes an end bearing seat 1, an end retaining ring 2, a fixing screw 3, an end rubber sleeve 4, a middle rubber sleeve 5, a driving end bearing seat 6, a welded steel roller 7, a drum-shaped tooth coupling 8, and a reduction motor 9.

[0026] The end bearing seat 1 and the driving end bearing seat 6, as the supporting components of the rubber-coated roller, adopt a structure combining steel machining and welding. Both ends of the welded steel roller 7 are respectively connected to the end bearing seat 1 and the driving end bearing seat 6. A plurality of middle rubber sleeves 5 are installed on the roller body of the welded steel roller 7, and end rubber sleeves 4 are installed on both sides. All rubber sleeves are of a combined structure of an inner ring and an outer ring. The outer ring is narrow, the inner ring is wide, the inner rings are axially adjacent to each other in sequence, the outer diameter of the inner ring and the inner diameter of the outer ring are in interference fit in the radial direction, and the inner diameter of the inner ring and the outer diameter of the welded steel roller 7 are in interference fit in the radial direction. After the outer ring rubber sleeve expands due to heat, it can still be consolidated with the inner ring rubber sleeve, and the inner ring rubber sleeve hardly expands. In this way, the overall rubber sleeve has good rotational synchronism relative to the welded steel roller 7, ensuring that during the transportation process, the surface of the steel plate is not scratched and the position of the steel plate is controlled relatively accurately.

[0027] The end retaining ring 2 is connected to the end faces at both ends of the welded steel roller 7 through fixing screws. The end retaining ring 2 is a split flange structure, and the flange back contacts both the roller body end face of the welded steel roller 7 and the end face of the end rubber sleeve 4 at the same time to limit all the rubber sleeves on the roller body.

[0028] The drum-shaped tooth coupling 8 and the reduction motor 9 are connected to the driving end of the welded steel roller 7 to provide power for the roller way transportation. The combined end rubber sleeve 4 and the middle rubber sleeve 5 have the characteristics of high positioning accuracy, not being prone to deviation during use, and good rotational synchronism between the combined rubber sleeve and the steel roller after heating. The split end retaining ring 5 has the characteristics of being convenient for disassembly and assembly, not scratching the bearing installation surface, not blocking the exhaust holes on the roller body of the welded steel roller, and effectively axially limiting the combined rubber sleeve. The above two structures are the main innovation points of the present utility model.

[0029] Compared with the conventional rubber-coated roller, the structure of the present utility model is simple and practical, convenient for disassembly and assembly, low in cost, perfect in function, and high in reliability. It integrates structure optimization and cost control, and has strong market competitiveness.

[0030] The above has described the present utility model in detail with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the knowledge scope of those of ordinary skill in the art. Many other changes and modifications made without departing from the concept and scope of the present utility model should be regarded as falling within the protection scope of the present utility model.

[0031] In the description of this specification, specific features, structures, materials, or characteristics may be combined in a suitable manner in any one or more of the embodiments or examples.

[0032] As described above, the above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered by the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
