Description

Technical Field

[0001] The utility model relates to the technical field of steel coil processing, in particular to a feeding device for steel coil production. Background Art

[0002] To facilitate transportation and storage, manufacturers typically coil thin steel sheets into coils. These coils typically weigh between 10 and 20 tons and have an outer diameter of up to 2 meters. Therefore, before the steel is subsequently processed into various products, the large coils must be cut horizontally or vertically into smaller sheets or coils. Due to the significant weight and volume of the coils, special equipment is required to transfer them to the uncoiler. Chinese utility model patent application number 201921525084.5, entitled "A New Type of Feeding Trolley," discloses a coil feeding trolley that supports the coils using two rollers. The rollers consist of a mandrel and a roller body mounted on the outside of the mandrel. Two inner bearings are positioned at opposite ends of the mandrel, with the outer rings of the inner bearings fixedly connected to the inner wall of the roller body. This allows the roller body to rotate about the mandrel, allowing the coil to rotate on the two rollers, thereby facilitating adjustment of the coil head's orientation. However, this technology presents the following technical issues:

[0003] Since the roller body is a tube structure (see the appendix of the specification of the above patent Figure 3 ), and in the length direction of the roller body, only the two ends are supported by internal bearings, and the rest is in a suspended state. As a result, when a steel coil weighing more than ten tons or even more than twenty tons is loaded on the roller body, the huge gravity of the steel coil can easily cause the middle part of the roller body to bend and deform, making it impossible for the roller body to rotate smoothly. This brings great inconvenience to the orientation adjustment of the steel coil head, increases the difficulty of positioning the steel coil and the uncoiler, and thus reduces the production efficiency of the entire steel coil cutting device. Therefore, during use, it is necessary to frequently check and replace the roller body or the winding roller in a timely manner, which makes the maintenance cost of the entire device high.

[0004] In view of the above technical problems still existing in the prior art, the applicant believes that it is very necessary to make technical improvements thereto in order to provide a feeding device for steel coil production that is not easily deformed and has low maintenance costs. Utility Model Content

[0005] The purpose of the present utility model is to solve the above-mentioned problems and shortcomings, and to provide a feeding device for steel coil production, which divides the roller into at least two roller units, and the two ends of each roller unit are rotatably connected to the central axis through bearing units, thereby greatly improving the load-bearing capacity of the roller unit, preventing it from bending and deformation, thereby extending the maintenance period of the device and reducing the equipment maintenance cost.

[0006] The technical solution of the present utility model is achieved as follows: a feeding device for steel coil production, comprising a moving mechanism and a steel coil carrying mechanism installed on the top of the moving mechanism, two roller assemblies are arranged side by side on the top of the steel coil carrying mechanism, and the roller assembly includes a central axis and a roller member sleeved on the outside of the central axis. Its characteristics are: the roller member is composed of at least two roller monomers, and each roller monomer is sleeved on the central axis in sequence along the length direction of the central axis, and the two ends of each roller monomer are rotatably connected to the central axis through a bearing member.

[0007] Furthermore, the steel coil carrying mechanism includes a carrying plate and two side positioning plates, the two side positioning plates are respectively arranged at the two ends of the carrying plate, and the two ends of the central axis are respectively installed on the two side positioning plates; at least one intermediate positioning plate for the central axis to bear is also provided on the carrying plate located between the two side positioning plates, and the roller unit is mounted on the central axis between the side positioning plate and the intermediate positioning plate or between the two intermediate positioning plates.

[0008] Furthermore, each side positioning plate and the top of the middle positioning plate are respectively provided with a positioning notch for the central axis to be embedded.

[0009] Furthermore, a plurality of reinforcing plates are provided on the surface of the bearing plate.

[0010] Furthermore, a polyurethane coating layer is provided on the surface of the roller unit.

[0011] Furthermore, the moving mechanism includes a mounting frame and at least one guide rod; the guide rod is vertically arranged at the bottom of the steel coil carrying mechanism, and a vertically penetrating guide hole is opened on the mounting frame, and the lower end of the guide rod can be vertically slidably inserted into the guide hole.

[0012] Furthermore, a guide tube is vertically embedded on the mounting frame, the upper end of the guide tube protrudes from the top of the mounting frame, a plurality of reinforcing ribs are arranged between the top surface of the mounting frame and the outer wall of the upper end of the guide tube, and the inner hole of the guide tube constitutes a guide hole.

[0013] The beneficial effects of the present invention are as follows: the present invention divides the roller into at least two roller units, and there are bearings between the two ends of the roller unit and the central axis to provide support; in this way, on the one hand, the length of the roller unit is small, and the degree of its deformation caused by pressure can be greatly reduced; on the other hand, the bearings can provide support at both ends of the roller unit, which is equivalent to adding multiple support points to the roller unit, thereby greatly improving the load-bearing capacity of the roller unit, and effectively preventing the roller unit from bending and deforming during use, thereby eliminating the need for frequent maintenance and replacement of the roller unit, and greatly reducing the maintenance cost of the equipment; even after long-term use, the present invention can still make the orientation adjustment of the steel coil head and the positioning of the steel coil and the uncoiler very convenient and accurate, BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0018] like Figure 1 、 2 As shown, the present application provides a feeding device for steel coil production, comprising a moving mechanism 1, a steel coil carrying mechanism 2 mounted on top of the moving mechanism 1, two roller assemblies 3 arranged side by side on top of the steel coil carrying mechanism 2, the roller assembly 3 comprising a central shaft 31 and a roller member 32 mounted outside the central shaft 31. To achieve the purpose of the present application, the roller member 32 is composed of at least two roller units 321, each roller unit 321 being mounted on the central shaft 31 in sequence and side by side along the length of the central shaft 31, with both ends of each roller unit 321 being rotatably connected to the central shaft 31 via bearing members 33. This greatly enhances the load-bearing capacity of the roller unit 32, and even if the roller unit 32 is subjected to the heavy pressure of the steel coil for a long time, it is not prone to bending or deformation, thereby enabling more stable adjustment of the orientation of the steel coil strip head, accurately positioning the steel coil and the uncoiler, and improving production efficiency.

[0019] like Figure 1 、 2As shown, the steel coil carrying mechanism 2 includes a carrying plate 21 and two side positioning plates 22. The two side positioning plates 22 are respectively arranged at the two ends of the carrying plate 21, and the two ends of the center shaft 31 are respectively installed on the two side positioning plates 22; at least one intermediate positioning plate 23 for supporting the center shaft 31 is also provided on the carrying plate 21 located between the two side positioning plates 22, and the roller unit 321 is mounted on the center shaft 31 between the side positioning plate 22 and the intermediate positioning plate 23 or between the two intermediate positioning plates 23. The number of intermediate positioning plates 23 can be determined according to actual conditions, preferably two. If the width of the steel coil to be processed is very large, the number can be increased as appropriate. In this way, the two side positioning plates 22 and the intermediate positioning plate 23 can provide support for both ends and the middle of the central axis 31, thereby enhancing the load-bearing capacity of the entire roller assembly 3, and further preventing the roller part 32 from bending and deforming during use. Even after long-term use, the roller part 32 can rotate very smoothly, thereby extending the maintenance cycle of the device and the replacement cycle of spare parts. At the same time, it can also greatly improve the stability of the device, more accurately and conveniently realize the docking of the steel coil and the uncoiler, and improve the transportation efficiency of the steel coil.

[0020] like Figure 2 As shown, the tops of the side positioning plates 22 are provided with positioning notches 221 for the center shaft 31 to fit into. There are two positioning notches 221, one side by one side, on the top of each side positioning plate 22. This allows the center shaft 31 to be directly inserted into the positioning notches 221 from above, thereby enabling rapid assembly of the two roller assemblies 3 and the side positioning plates 22. Similarly, the top surface of the middle positioning plate 23 also has two positioning notches 221 (not shown) for the center shaft 31 to fit into, side by side.

[0021] like Figure 1 As shown, a plurality of reinforcing plates 24 are provided on the surface of the bearing plate 21 , which can further enhance the mechanical strength of the bearing plate 21 and prevent the bearing plate 21 from bending or deforming under the heavy pressure of the steel coil.

[0022] like Figure 1 As shown, the bearing assembly 33 is composed of at least two bearing units 331 arranged side by side. The two or more bearing units 331 support each other, reducing the load on a single pair of bearing units 331 and significantly increasing the bearing capacity of the bearing assembly 33. Furthermore, the mutual support of the two or more bearing units 331 prevents axial and radial displacement of the bearing units 331, significantly improving the rotational stability of the bearing assembly 33. This allows the present invention to operate very smoothly even when subjected to the weight of steel coils weighing tens or even hundreds of tons for extended periods of time.

[0023] like Figure 1As shown, the surface of the roller unit 321 is provided with a polyurethane coating 34. In the present invention, the roller unit 321 is a steel structure, and the polyurethane coating 34 is provided on the steel structure. This prevents hard contact between the steel coil and the roller unit 321 when the steel coil is placed on the steel coil support mechanism 2. This not only prevents scratches on the steel coil surface, but also cushions the impact on the roller unit 321 when the steel coil is lowered, reducing damage to the roller unit 321, thereby helping to extend the service life of the roller unit 321 and the steel coil support mechanism 2.

[0024] like Figure 1 、 2 As shown in Figures 3 and 4, the movable mechanism 1 includes a mounting frame 11 and at least one guide rod 12. The guide rod 12 is vertically mounted at the bottom of the coil support mechanism 2. A guide hole 13 extending vertically through the mounting frame 11 is defined, into which the lower end of the guide rod 12 is vertically slidably inserted. When the hydraulic cylinder 17 drives the coil support mechanism 2 to move vertically, the guide rod 12 provides guidance and support for the coil support mechanism 2, maintaining its balance. This prevents friction and wear between the piston rod and the cylinder body of the hydraulic cylinder, thereby extending the service life of the hydraulic cylinder 17.

[0025] like Figure 1-Figure 3 As shown, a guide tube 14 is vertically embedded in the mounting frame 11. The upper end of the guide tube 14 protrudes from the top of the mounting frame 11. A number of reinforcing ribs 15 are provided between the top surface of the mounting frame 11 and the outer wall of the upper end of the guide tube 14. The inner hole of the guide tube 14 forms the guide hole 13. The support of the reinforcing ribs 15 enhances the mechanical strength of the upper end of the guide tube 14, thereby better guiding the guide rod 12, better maintaining the balance of the steel coil carrying mechanism 2, and further protecting the hydraulic cylinder 17.

[0026] like Figure 1-Figure 3 As shown, bearing reinforcement rings 16 are further provided on the left and right side walls of the mounting frame 11. Also mounted on the mounting frame 11 are guide wheels 19 for horizontally moving the moving mechanism 1, as well as a drive motor 18. The guide wheels 19 are movably connected to the left and right sides of the mounting frame 11 via an axis. The left and right side walls of the mounting frame 11 are rotatably connected to the axis via bearings. Because this connection needs to withstand a large force, bearing reinforcement rings 16 are provided on the side walls of the mounting frame 11 located next to the axis to enhance the mechanical strength of this area, prevent deformation and cracking of the mounting frame 11, and thus improve the reliability and service life of the present invention.
