Abstract
Description
Technical Field
[0001] This utility model relates to the field of material conveying, and in particular to a rolling mill feeding structure that is easy to adjust. Background Technology
[0002] In the metal rolling process, the metal billet to be processed needs to be stably and accurately transported between the rolls of the rolling mill through the mill feeding structure to ensure the smooth progress of the rolling process and the quality of the rolled products.
[0003] In traditional rolling mill feeding methods, the feed rolls are typically installed in a fixed position. This fixed installation method has many limitations when dealing with metal billets of different specifications and thicknesses. For example, when rolling billets of different thicknesses, because the position of the feed rolls cannot be adjusted, the billet may not make close contact with the feed rolls during transport, leading to unstable feeding, slippage, and consequently affecting rolling accuracy and product quality. Moreover, fixed feeding structures are difficult to adapt to diverse production needs. When production tasks change and require processing billets of different sizes, complex adjustments to the entire feeding system or even replacement of some components are often necessary. This not only increases production costs but also consumes a significant amount of time and manpower, reducing production efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a rolling mill feeding structure that is easy to adjust, solving the problem that traditional feeding structures are difficult to adapt to billets of different specifications due to the fixed position of the feeding rollers.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A mill feeding structure that is easy to adjust includes a support frame. Vertical plates are symmetrically fixedly connected to the top of the support frame. Vertical grooves are equidistantly opened on the surface of the vertical plates. The top of the vertical grooves is open. Two movable seats are slidably connected inside the vertical grooves. A driving roller and a driven roller are provided between the vertical grooves of the two vertical plates. The two ends of the driving roller and the driven roller are rotatably connected to the corresponding movable seats. A conveying sleeve is fitted on the outside of the driving roller and the driven roller. Positioning sleeves are also fitted on both ends of the conveying sleeves on the outside of the driving roller and the driven roller. Annular grooves are symmetrically opened on the outside of the driving roller and the driven roller. Positioning rings are fitted on the outside of the annular grooves.
[0006] Preferably, the movable seat is equipped with bearings, and the two ends of the driving roller and the driven roller are slidably inserted into the corresponding bearings. The bearings reduce the rotational friction between the driving roller, the driven roller and the movable seat, and the insertion method also facilitates disassembly and installation.
[0007] Preferably, each of the vertical slots on the upright plate is fixedly connected to a fixed seat. The fixed seat is internally threaded with a threaded rod. The bottom of the threaded rod is rotatably connected to a fixed strip. The bottom of the fixed strip is fixedly connected to the corresponding movable seat. By rotating the threaded rod, the threaded rod will move up or down relative to the fixed seat using the threaded transmission principle between the threaded rod and the fixed seat, thereby adjusting the movable seat.
[0008] Preferably, the two ends of the fixing base are fixedly connected to the upright plate by bolts. This connection method has the advantage of convenient installation and disassembly.
[0009] Preferably, support rods are fixedly connected at equal intervals between the tops of the uprights. The presence of the support rods effectively disperses the force borne by the uprights and improves the load-bearing capacity of the uprights.
[0010] Preferably, both the driving roller and the driven roller have strip-shaped grooves on their outer sides, and the inner wall of the conveying sleeve has protrusions. The protrusions are slidably connected to the corresponding strip-shaped grooves, so that the conveying sleeve can rotate synchronously with the driving roller and the driven roller, and avoid relative sliding between the conveying sleeve and the driving roller and the driven roller.
[0011] Preferably, the positioning ring includes an upper semi-circular ring and a lower semi-circular ring. The upper and lower semi-circular rings are rotatably connected at one end and fixedly connected at the other end by bolts. The structure of the upper and lower semi-circular rings being rotatably connected and fixed by bolts makes installation and disassembly very convenient.
[0012] Compared with the prior art, the advantages of this utility model are as follows:
[0013] This invention allows for easy adjustment of the distance between the active and driven rollers by sliding the movable seat within the vertical groove of the upright plate, thus adapting to the feeding requirements of materials of different thicknesses. Furthermore, the screw drive between the threaded rod and the fixed seat enables precise adjustment of the movable seat's position, making operation simple.
[0014] This utility model's conveyor sleeve is slidably connected to the strip-shaped grooves on the outside of the driving and driven rollers via a raised strip. During installation and disassembly, it is only necessary to slide the raised strip into or out of the strip-shaped groove. This facilitates the replacement of conveyor sleeves of specific specifications according to the characteristics of different materials, thereby improving the versatility and adaptability of the equipment.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Please see Figures 1 to 4 This embodiment provides an easily adjustable mill feeding structure, including a support 1. A vertical plate 2 is symmetrically fixedly connected to the top of the support 1. Vertical grooves 21 are equidistantly spaced on the surface of the vertical plate 2. The top of each vertical groove 21 is open. Two movable seats 3 are slidably connected inside each vertical groove 21. A driving roller 4 and a driven roller 5 are provided between the vertical grooves 21 of the two vertical plates 2. Both ends of the driving roller 4 and the driven roller 5 are rotatably connected inside their respective movable seats 3. A conveying sleeve 6 is fitted on the outer side of both the driving roller 4 and the driven roller 5. Positioning sleeves 7 are also fitted on both ends of the conveying sleeve 6 on the outer side of both the driving roller 4 and the driven roller 5. Annular grooves 8 are symmetrically spaced on the outer side of both the driving roller 4 and the driven roller 5. Positioning rings 9 are fitted on the outer side of the annular grooves 8.
[0022] When it is necessary to adjust the distance between the driving roller 4 and the driven roller 5, the operator can push the movable seat 3 with external force, so that the movable seat 3 slides up and down along the vertical groove 21, thereby driving the driven roller 5 to move, so as to adjust the distance between it and the driving roller 4. The conveying sleeve 6 is used to directly contact the material and convey it. According to the characteristics of different materials, the conveying sleeve 6 of a specific specification can be replaced to meet the diverse feeding requirements. After installing the conveying sleeve 6, first put the positioning sleeve 7 on the driving roller 4 and the driven roller 5 and abut against the end of the conveying sleeve 6. Then, insert the positioning ring 9 into the annular groove 8 so that the positioning ring 9 contacts the positioning sleeve 7, thereby fixing the conveying sleeve 6 tightly in the designated position of the driving roller 4 and the driven roller 5, ensuring that the conveying sleeve 6 will not shift during the feeding process.
[0023] The power system of the rolling mill drives the drive roller 4 to rotate. The drive roller 4 contacts the material through the conveying sleeve 6 fitted on its outer side. When the drive roller 4 rotates, the friction will drive the conveying sleeve 6 and the material in contact with it to move together. The driven roller 5 is also fitted with the conveying sleeve 6. Driven by the material, the driven roller 5 will rotate with the rotation of the material and the drive roller 4, playing the role of assisting in conveying and supporting the material, ensuring that the material can be conveyed forward smoothly and continuously.
[0024] The movable seat 3 is equipped with a bearing 10. The two ends of the driving roller 4 and the driven roller 5 are slidably inserted into the corresponding bearing 10. The bearing 10 can reduce the rotational friction between the driving roller 4, the driven roller 5 and the movable seat 3, so that the driving roller 4 and the driven roller 5 can rotate more smoothly under the drive of the drive device, thereby achieving efficient feeding. At the same time, the two ends of the driving roller 4 and the driven roller 5 are slidably inserted into the bearing 10, which facilitates the disassembly and installation of the driving roller 4 and the driven roller 5.
[0025] The top of the vertical groove 21 of the upright plate 2 is fixedly connected to a fixed seat 11. The fixed seat 11 is internally threaded with a threaded rod 12. The bottom of the threaded rod 12 is rotatably connected to a fixed strip 13. The bottom of the fixed strip 13 is fixedly connected to the corresponding movable seat 3. When it is necessary to adjust the vertical position of the driving roller 4 and the driven roller 5, the operator rotates the threaded rod 12. Under the action of the threaded transmission, the threaded rod 12 will move up or down relative to the fixed seat 11. The up and down movement of the threaded rod 12 will drive the fixed strip 13 and the movable seat 3 to move synchronously along the vertical groove 21, thereby realizing the adjustment of the vertical position of the driving roller 4 and the driven roller 5 to meet the feeding requirements of materials of different thicknesses.
[0026] The two ends of the fixed base 11 are fixedly connected to the upright plate 2 by bolts. The connection method of using bolts to connect the two ends of the fixed base 11 to the upright plate 2 has the advantages of convenient installation and disassembly. During installation, the fixed base 11 is placed in a suitable position on the upright plate 2, and then the bolts are passed through the preset holes on the fixed base 11 and the upright plate 2 in sequence and tightened to achieve a stable connection between the fixed base 11 and the upright plate 2.
[0027] Support rods 14 are fixedly connected at equal intervals between the tops of the vertical plates 2. The support rods 14 can enhance the structural strength and stability of the entire feeding structure, so that the vertical plates 2 are not easily deformed or shaken when subjected to the gravity of the driving roller 4, driven roller 5 and materials, ensuring the positional accuracy and operational stability of each component during the feeding process, thereby improving the quality and efficiency of mill feeding.
[0028] Both the driving roller 4 and the driven roller 5 have strip-shaped grooves 15 on their outer sides, and the inner wall of the conveying sleeve 6 has protrusions 16. The protrusions 16 are slidably connected to the corresponding strip-shaped grooves 15. When installing the conveying sleeve 6, the protrusions 16 on the inner wall of the conveying sleeve 6 are aligned with the strip-shaped grooves 15 on the outer sides of the driving roller 4 and the driven roller 5. Then, the conveying sleeve 6 is pushed so that the protrusions 16 slide into the strip-shaped grooves 15. Through this structure, when the driving roller 4 and the driven roller 5 rotate, the strip-shaped grooves 15 can limit and guide the protrusions 16, so that the conveying sleeve 6 can rotate synchronously with the driving roller 4 and the driven roller 5, avoiding relative sliding between the conveying sleeve 6 and the driving roller 4 and the driven roller 5, thereby ensuring the stability and accuracy of material conveying. At the same time, this sliding connection method also facilitates the installation and disassembly of the conveying sleeve 6, and makes it convenient to replace the conveying sleeve 6 with the appropriate specification according to different materials.
[0029] The positioning ring 9 includes an upper semi-circular ring 91 and a lower semi-circular ring 92. The upper semi-circular ring 91 and the lower semi-circular ring 92 are rotatably connected at one end and fixedly connected at the other end by bolts. When installing the positioning ring 9, since the upper semi-circular ring 91 and the lower semi-circular ring 92 are rotatably connected at one end, the lower semi-circular ring 92 can be placed first at the corresponding position of the annular groove 8 of the driving roller 4 or the driven roller 5. Then, the upper semi-circular ring 91 is rotated around the rotatable connection point to close it with the lower semi-circular ring 92. At this point, the positioning ring 9 is initially positioned. The upper half-ring 91 and the lower half-ring 92 are fitted onto the annular groove 8. Then, the bolts are passed through the pre-set holes at the other ends of the upper half-ring 91 and the lower half-ring 92 and tightened to secure the upper half-ring 91 and the lower half-ring 92 together. This securely installs the positioning ring 9 in the annular groove 8, further limiting the position of the conveying sleeve 6. When it is necessary to remove the positioning ring 9, simply loosen the bolts and open the upper half-ring 91 around the rotating connection point to easily remove the positioning ring 9 from the annular groove 8. The operation is simple and quick.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
