Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, and in particular to a feeding device for an uncoiler. Background Technology

[0002] Uncoiling machines are core equipment in metal sheet processing production lines. They are mainly used to smoothly and continuously unwind coiled strips, providing a stable supply of raw materials for subsequent processes such as leveling, stamping, and cutting.

[0003] Traditional uncoilers require workers to operate forklifts to place steel coils on a placement platform. Then, hydraulic cylinders are used to control the height adjustment of the placement platform to make the steel coil coaxial with the uncoiler's main shaft. The placement platform then moves to move the steel coil onto the uncoiler's main shaft to complete the loading operation.

[0004] However, when the steel coil is placed on the uncoiler's mounting table, its large weight and strong inertia make it prone to rolling and swaying, making it difficult for the coil to be coaxial with the uncoiler's main shaft and increasing the difficulty of adjustment. Manual operation requires repeated fine-tuning to align with the uncoiler's centerline, which is not only inefficient but also poses safety hazards. Utility Model Content

[0005] The purpose of this invention is to provide a feeding device for an uncoiler to solve the problems mentioned in the background art.

[0022] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] In current technology, when steel coils are placed on the uncoiler's mounting table, their large weight and strong inertia cause them to easily roll and sway, making it difficult for the coils to be coaxial with the uncoiler's main shaft and increasing the difficulty of adjustment. Manual operation requires repeated fine-tuning to align with the uncoiler's centerline, which is not only inefficient but also poses safety hazards.

[0025] like Figure 1-4As shown, this utility model embodiment provides a feeding device for an uncoiler, including a cabinet 1. A push rail 101 is fixedly connected to the bottom of the cabinet 1. A roller 102 is rotatably connected to one end of the cabinet 1. A hydraulic tank 2 is slidably connected inside the push rail 101. A hydraulic rod 201 is movably connected to the top of the hydraulic tank 2. A placement platform 202 is fixedly connected to the top of the hydraulic rod 201. A limiting mechanism 4 is slidably connected to the top of the placement platform 202. A driving mechanism 3 is fixedly connected to the bottom of the limiting mechanism 4. The limiting mechanism 4 includes a mounting frame 401. Support rods 402 are fixedly connected to both sides of the mounting frame 401. A parking block 403 is movably connected to the inner side of the support rods 402 through a fixing pin. A mounting block 404 is fixedly connected to the side of the parking block 403 near the mounting frame 401. A damper 405 is movably connected to one side of the mounting block 404 through a fixing pin. The damper 405 is hinged to the mounting frame 401 away from the mounting block 404 through a fixing pin.

[0026] The cabinet 1 serves as the overall support structure. The bottom push rail 101 slides with the hydraulic tank 2 via a linear guide rail, allowing the hydraulic tank 2 to move smoothly along the rail. The hydraulic rod 201 is installed on the top of the hydraulic tank 2 and achieves multi-stage lifting through hydraulic drive, driving the placement platform 202 to move up and down to accommodate height adjustments for steel coils of different diameters.

[0027] In use, the steel coil is placed on the placement platform 202 using a crane. Then, the motor 301 starts, driving the first transmission wheel 302 to rotate. The first transmission wheel 302 transmits power to the second transmission wheel 304 via the chain 303, which in turn drives the lead screw 305 to rotate. The lead screw 305 has threads on its surface and is threadedly connected to the moving block 306 on the limiting mechanism 4. When the lead screw 305 rotates, the moving block 306 moves axially along the lead screw 305 under the action of the threads, thereby driving the limiting mechanism 4 to move on the placement platform 202. When the limiting mechanism 4 moves to the position of the steel coil, the arc-shaped concave part of the stopping block 403... The groove conforms to the outer wall of the steel coil, providing initial support and constraint. One end of the damper 405 is movably connected to the mounting block 404 via a fixing pin, and the other end is hinged to the mounting frame 401 via a fixing pin. When the steel coil is placed on the parking block 403, the weight of the steel coil will exert pressure on the parking block 403, causing the parking block 403 to rotate at a certain angle around its connection point with the support rod 402. At this time, the damper 405 will automatically adjust its extension length according to the pressure. By adjusting the extension length of the damper 405, the impact force can be buffered, reducing the impact on the device and extending the service life of the device. ，The rotation of the parking block 403 is buffered and restricted, so that the parking block 403 can fit the steel coil at a suitable angle and force, further enhancing the stability of the steel coil. The driving mechanism 3 drives the limiting mechanism 4 to move to a suitable position, and with the coordinated action of the various parts of the limiting mechanism 4, the steel coil placed on the placement table 202 can be stably fixed, preventing the steel coil from shaking, rolling or shifting during the feeding process.

[0028] Furthermore, a barrier 203 is fixedly connected to the top of the placement platform 202, and an movable groove 204 is provided on the top of the placement platform 202, with the drive mechanism 3 located within the movable groove 204.

[0029] The 203 fencing effectively ensures the safety of the steel coils, preventing them from falling and causing damage or safety accidents.

[0030] Furthermore, the drive mechanism 3 includes a motor 301, one end of which is fixedly connected to a first transmission wheel 302, a chain 303 meshing with the surface of the first transmission wheel 302, one end of which is meshed with a second transmission wheel 304, a lead screw 305 fixedly connected to one side of the first transmission wheel 302, a moving block 306 threadedly connected to the surface of the lead screw 305, a connecting block 307 fixedly connected to the top of the moving block 306, and the connecting block 307 fixedly connected to the limiting mechanism 4.

[0031] The motor 301 drives the lead screw 305 to rotate, thereby realizing the automatic movement of the limit mechanism 4. The position of the limit mechanism 4 can be adjusted quickly and accurately to adapt to steel coils of different sizes, which improves the automation and efficiency of feeding and reduces the labor intensity and error of manual operation.

[0032] Furthermore, the top of the parking block 403 is provided with an arc-shaped groove for fitting the outer wall of the steel coil, and the dampers 405 are symmetrically distributed on both sides of the parking block 403.

[0033] When the steel coil is placed on the placement platform 202, the damper 405 of the parking block 403 undergoes elastic deformation under the pressure of the outer wall of the steel coil, so that the parking block 403 is adjusted at a certain angle according to the shape of the outer wall of the steel coil, thereby making the arc-shaped groove on the top of the parking block 403 fit better against the outer wall of the steel coil.

[0034] Furthermore, the enclosure 203 has a U-shaped structure and is set up on three sides of the placement platform 202.

[0035] Furthermore, the lead screw 305 consists of a central round rod and two threaded sections on both sides, with the threads on both sides in opposite directions.

[0036] This lead screw 305 structure design allows the two moving blocks 306 to move simultaneously to the middle or to the sides.

[0037] Furthermore, both ends of the lead screw 305 are rotatably connected to the placement platform 202 via bearing seats.

[0038] The bearing housing connection method ensures the rotational accuracy and stability of the lead screw 305, reduces the wear and wobble of the lead screw 305, and improves the reliability and service life of the drive mechanism 3.

[0039] Furthermore, the internal linear guide rail of the push track 101 cooperates with the sliding groove at the bottom of the hydraulic box 2 to achieve smooth movement, which is beneficial to the docking of the steel coil and the roller 102.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
