Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of logistics conveying equipment, specifically a cylindrical vertical rotating mechanism. Background Technology
[0002] Online buffer conveying devices are crucial equipment in logistics processes, especially in the production of cigarette sticks or filter rods, where material buffering requires the rotation of a spiral storage cylinder. Existing spiral storage cylinder rotation structures consist of several upper axial support bearings 13 and several upper radial support bearings 14 mounted on an upper fixed plate 12 above the cylinder 11, and several lower axial support bearings 15 and several lower radial support bearings 16 mounted below the cylinder 11. A drive gear 17 drives the cylinder 11 to rotate around a central support column 18. Figure 1 and Figure 2 As shown, this structure requires that the support seats of each axial bearing be of high precision and equal height, and that the radial circumferential positioning be coaxial with the cylinder. This is difficult to achieve, so manual adjustment is required during assembly. It is almost impossible for each bearing to withstand axial force, especially the radial coaxiality, which is difficult to adjust to an accuracy within 0.2mm. This is not only time-consuming and labor-intensive, but also poses a risk of unstable operation. Utility Model Content
[0003] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a cylindrical vertical rotating mechanism that is simple in structure, accurately positioned in both vertical and horizontal directions, requires no manual adjustment, and operates stably.
[0004] To solve the above-mentioned technical problems, this utility model provides a cylindrical vertical rotating mechanism, including a fixed base and a rotating cylinder. A fixed inner ring is fixed on the fixed base. The bottom of the rotating cylinder is fixedly connected to a rotating outer ring and is coaxial with the rotating outer ring. The rotating outer ring is rotatably connected to the outside of the fixed inner ring through several rolling elements. The rotating outer ring is fixed in both the vertical and horizontal directions and can only rotate. The rotating outer ring is connected to a driving mechanism, which drives the rotating outer ring to rotate around the fixed inner ring, thereby driving the rotating cylinder to rotate.
[0005] As a further description of the above technical solution, the outer side of the rotating outer ring is provided with a toothed structure, and the driving mechanism includes a driving gear. The toothed structure meshes with the driving gear, thereby driving the rotating outer ring to rotate under the drive of the driving mechanism.
[0006] As a further description of the above technical solution, the tooth structure is a straight tooth structure.
[0007] As a further description of the above technical solution, the outer side of the fixed inner ring is provided with an outer raceway that cooperates with the rolling element, and the inner side of the rotating outer ring is provided with an inner raceway that cooperates with the rolling element. The rolling element is located in the raceway cavity formed by the outer raceway and the inner raceway, and can roll along the raceway cavity.
[0008] As a further description of the above technical solution, several rolling elements are evenly distributed in one or two rings along the outer side of the fixed inner ring.
[0009] As a further description of the above technical solution, the rolling body is a sphere, cylinder, or cone.
[0010] As a further description of the above technical solution, the bottom of the fixed base is also provided with shock-absorbing and leveling feet.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This invention fixes the rotating cylinder to a rotating outer ring, restricting its vertical movement. The rotating outer ring is connected to the outside of a fixed inner ring via rolling elements. The fixed inner ring is fixed to a fixed base, restricting its horizontal movement, so that it can only rotate around the fixed inner ring, thereby driving the rotating cylinder fixedly connected to it to rotate. A toothed structure is provided on the outer side of the rotating outer ring for meshing with the drive mechanism to provide rotational power. Leveling feet are provided at the bottom of the fixed base to level the entire mechanism and reduce vibration, improving operational stability. This invention's vertical rotating cylinder mechanism has the advantages of simple structure, precise positioning in both vertical and horizontal directions, no need for manual adjustment, and stable operation.
