Description

A winding machine for producing galvanized steel coils Technical Field

[0001] This utility model relates to the field of winding machine technology, specifically a winding machine for producing galvanized steel coils. Background Technology

[0002] Galvanized steel coil is a steel product produced by hot-dip galvanizing. Its main characteristic is that its surface is covered with a layer of zinc. This treatment can effectively prevent the steel from corroding when exposed to the atmosphere, thereby extending its service life. After the rough processing of the steel coil is completed, it needs to be finely processed, such as being cut into size and rewound. Traditional winding devices often do not have a central clamping limit to prevent the steel coil from shifting during the winding process, resulting in poor winding effect. In order to improve this situation, a winding machine for the production of galvanized steel coil is proposed.

[0003] For example, the winding machine for producing galvanized steel coils disclosed in the authorization announcement number CN221875931U includes a main bearing platform of the winding machine, a main drive motor, a movable bearing platform, a split bearing block, a movable roller, a main winding bearing shaft, a main winding shaft mounting platform, a No. 4 bevel gear, a No. 2 bevel gear, a No. 1 bevel gear, a sliding drive rod, a lower gear connecting platform, a split block adjusting block, a transition gear shaft, a positioning screw, and an adjusting linkage rod. The main drive motor is connected to the rear of the main bearing platform of the winding machine, the No. 1 bevel gear is connected to the front of the main drive motor, the upper part of the No. 2 bevel gear is connected to the main bearing platform of the winding machine, the No. 2 bevel gear meshes with the No. 1 bevel gear, the bottom of the No. 2 bevel gear is connected to the sliding drive rod, the bottom of the sliding drive rod is connected to the main winding shaft mounting platform, and the bottom of the transition gear shaft is connected to the main winding shaft mounting platform.

[0004] Although it achieves the lowering of the main winding shaft mounting platform controlled by the lifting hydraulic cylinder, causing the split-type bearing block and the main winding bearing column connector to descend as a whole, the completed galvanized steel coil is placed on the upper part of the movable bearing platform. The movable bearing platform supports the galvanized steel coil, and the steel coil itself is no longer pressed against the side of the split-type bearing block. By loosening the positioning screws, the split-type bearing block is retracted, which makes it easy to remove the galvanized steel coil. During the removal process, the steel coil itself does not have excessive friction with the split-type bearing block, making the recycling process of the galvanized steel coil safer.

[0005] However, it does not solve the problem that existing winding machines are not conducive to convenient linkage and pressure limiting of steel coils to prevent steel plates from uncoiling during the winding process, nor are they conducive to centering and clamping the steel plates to prevent them from deviating, thus affecting the quality of steel plate winding. Summary of the Invention

[0006] The purpose of this utility model is to provide a winding machine for producing galvanized steel coils, so as to solve the problems mentioned in the background art, which are that the winding machine is not convenient to link and press the steel coil to prevent the steel plate from uncoiling during the winding process, and is not conducive to centering and clamping the steel plate to prevent the steel plate from deviating, thus affecting the quality of steel plate winding.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a winding machine for producing galvanized steel coils, comprising a flattening frame and a roller conveyor. A roller conveyor is provided on one side of the flattening frame, and a winding frame is provided on one side of the roller conveyor. A servo motor is installed on the outer wall of the roller conveyor, and a bidirectional lead screw is installed at the output end of the servo motor. The bidirectional lead screw is movably connected to the roller conveyor. Two sets of threaded sleeves are fitted on the surface of the bidirectional lead screw, and the threaded sleeves are threadedly connected to the bidirectional lead screw. Two sets of integrated frames are slidably installed at the top of the roller conveyor, and the integrated frames are connected to the threaded sleeves. Multiple sets of equally spaced limiting wheels are movably installed inside each integrated frame.

[0008] Preferably, an L-shaped frame is installed on one side of the winding frame, a drive mechanism is installed on the outer wall of the winding frame, and a winding roller is installed at the power output end of the drive mechanism, and the winding roller is movably connected to the winding frame.

[0009] Preferably, a second hydraulic cylinder is symmetrically and movably mounted on the side wall of the L-shaped frame, and a second push arm is mounted on the output end of each of the second hydraulic cylinders.

[0010] Preferably, the end of the second push arm away from the second hydraulic cylinder is provided with a linkage arm, and the side of the linkage arm close to the second push arm is provided with a linkage shaft, and the linkage arm is movably connected to the second push arm through the linkage shaft.

[0011] Preferably, each of the linkage arms is provided with a hinge shaft at one end near the L-shaped frame, and the linkage arm is movably connected to the L-shaped frame through the hinge shaft, and a pressure roller is movably installed between the two sets of linkage arms.

[0012] Preferably, three sets of lower leveling rollers with equal spacing are movably installed inside the leveling frame, and two sets of first hydraulic cylinders are symmetrically installed on the inner wall of the leveling frame.

[0013] Preferably, each of the first hydraulic cylinders has a first push arm installed at its output end, and a lower pressure block is provided on the outside of the first hydraulic cylinder, and the lower pressure block is connected to the first push arm.

[0014] Preferably, two sets of upper leveling rollers are provided on one side of the lower pressing block, and the upper leveling rollers are movably connected to the lower pressing block.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the winding machine not only realizes the convenient linkage pressing and limiting of the steel coil to prevent the steel plate from unwinding during the winding process, but also facilitates the centering, clamping and limiting of the steel plate to prevent it from deviating, and improves the quality of steel plate winding.

[0016] (1) The galvanized steel sheet passes between the lower and upper leveling rollers, between the two sets of integrated frames, and connects with the take-up roller. The second hydraulic cylinder drives the second push arm to move, and the second push arm drives the linkage arm to rotate around the hinge axis via the linkage shaft. The linkage arm drives the pressure roller to rotate, so that the pressure roller rotates and contacts the surface of the galvanized steel sheet. The pressure roller applies pressure and limits the galvanized steel sheet. The drive mechanism drives the take-up roller to rotate, and the take-up roller coils the steel sheet. As the diameter of the steel coil gradually increases, the second hydraulic cylinder also works synchronously to drive the second push arm to gradually retract, thereby bringing... The moving pressing rollers move gradually to better adapt to steel coils of different diameters. During the coiling process, to prevent displacement of the steel plate and improve its coiling accuracy, a servo motor drives a bidirectional lead screw to rotate. The bidirectional lead screw drives two sets of threaded sleeves to move closer to each other. The threaded sleeves drive the integrated frame and the limiting wheel to move closer to each other and make the limiting wheel contact the two sides of the steel plate to center, clamp, and limit the steel plate to prevent it from deviating. This achieves convenient linkage pressing and limiting of the steel coil to prevent the steel plate from uncoiling during the coiling process and facilitates centering, clamping, and limiting the steel plate to prevent it from deviating.

[0017] (2) During the movement of the steel plate, the first hydraulic cylinder drives the first push arm to move, the first push arm drives the lower pressure block to move downward, and the lower pressure block drives the upper leveling roller to move downward, so that the upper leveling roller contacts the upper surface of the steel plate and the lower leveling roller contacts the lower surface of the steel plate. Under the staggered contact of the upper and lower leveling rollers, the steel plate is rolled flattened to improve the flatness of the steel plate and thus improve the quality of the steel plate coiling.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please refer to Figures 1-5. One embodiment of this utility model is provided: a winding machine for producing galvanized steel coils, including a flattening frame 1 and a roller conveyor 2. The roller conveyor 2 is provided on one side of the flattening frame 1, and a winding frame 3 is provided on one side of the roller conveyor 2. A servo motor 20 is installed on the outer wall of the roller conveyor 2, which serves as a power drive. A bidirectional lead screw 21 is installed at the output end of the servo motor 20, and the bidirectional lead screw 21 is movably connected to the roller conveyor 2. Two sets of threaded sleeves 22 are fitted on the surface of the bidirectional lead screw 21, and the threaded sleeves 22 are threadedly connected to the bidirectional lead screw 21. Two sets of integrated frames 6 are slidably installed on the top of the roller conveyor 2, and the integrated frames 6 are connected to the threaded sleeves 22. Multiple sets of equidistant limit wheels 19 are movably installed inside the integrated frames 6.

[0026] An L-shaped frame 13 is installed on one side of the winding frame 3, a drive mechanism 12 is installed on the outer wall of the winding frame 3, and a winding roller 4 is installed at the power output end of the drive mechanism 12, and the winding roller 4 is movably connected to the winding frame 3.

[0027] The second hydraulic cylinders 15 are symmetrically and movably installed on the side wall of the L-shaped frame 13. The second hydraulic cylinders 15 serve as power drives, and the output end of each second hydraulic cylinder 15 is equipped with a second push arm 16. The end of each second push arm 16 away from the second hydraulic cylinder 15 is provided with a linkage arm 18. The side of each linkage arm 18 close to the second push arm 16 is provided with a linkage shaft 17, and the linkage arm 18 is movably connected to the second push arm 16 through the linkage shaft 17.

[0028] Each of the linkage arms 18 is provided with a hinge shaft 14 at one end near the L-shaped frame 13, and the linkage arms 18 are movably connected to the L-shaped frame 13 through the hinge shaft 14. A pressure roller 5 is movably installed between the two sets of linkage arms 18.

[0029] The galvanized steel sheet is passed between the lower leveling roller 7 and the upper leveling roller 8, through the two sets of integrated frames 6, and connected to the take-up roller 4. The second hydraulic cylinder 15 is opened, which drives the second push arm 16 to move. The second push arm 16 drives the linkage arm 18 to rotate around the hinge shaft 14 via the linkage shaft 17. The linkage arm 18 drives the pressure roller 5 to rotate, so that the pressure roller 5 contacts the surface of the galvanized steel sheet, and the pressure roller 5 applies pressure and limits the galvanized steel sheet. Then, the drive mechanism 12 is opened, which drives the take-up roller 4 to rotate, and the take-up roller 4 winds up the steel sheet. As the diameter of the steel coil gradually increases, the second hydraulic cylinder 15 also works synchronously to drive the second push arm 16 to gradually retract, thereby driving the pressure roller 5 to gradually move. This allows for better adaptation to steel coils of different diameters. To prevent displacement of the steel plate during the coiling process and improve coiling accuracy, the servo motor 20 can be turned on. The servo motor 20 drives the bidirectional lead screw 21 to rotate. With the threaded connection between the bidirectional lead screw 21 and the threaded sleeve 22, and the sliding cooperation between the integrated frame 6 and the roller frame 2, the bidirectional lead screw 21 drives the two sets of threaded sleeves 22 to approach each other. The threaded sleeves 22 drive the integrated frame 6 and the limiting wheel 19 to approach each other and make the limiting wheel 19 contact the two sides of the steel plate to center, clamp, and limit the steel plate to prevent it from deviating. This achieves convenient linkage, pressure, and limiting of the steel coil to prevent the steel plate from uncoiling during the coiling process, and facilitates centering, clamping, and limiting the steel plate to prevent it from deviating.

[0030] The flattening frame 1 has three sets of equally spaced lower flattening rollers 7 installed inside. Two sets of first hydraulic cylinders 9 are symmetrically installed on the inner wall of the flattening frame 1. The output end of each first hydraulic cylinder 9 is equipped with a first push arm 10, and a lower pressure block 11 is provided on the outside of the first hydraulic cylinder 9. The lower pressure block 11 is connected to the first push arm 10.

[0031] Two sets of upper leveling rollers 8 are provided on one side of the lower pressure block 11, and the upper leveling rollers 8 are movably connected to the lower pressure block 11.

[0032] Meanwhile, in order to ensure the flatness of the steel plate during the coiling process, the first hydraulic cylinder 9 is opened during the movement of the steel plate. The first hydraulic cylinder 9 drives the first push arm 10 to move, the first push arm 10 drives the lower pressure block 11 to move downward, and the lower pressure block 11 drives the upper leveling roller 8 to move downward, so that the upper leveling roller 8 contacts the upper surface of the steel plate and the lower leveling roller 7 contacts the lower surface of the steel plate. Under the staggered contact of the upper leveling roller 8 and the lower leveling roller 7, the steel plate is rolled flat to improve the flatness of the steel plate, thereby improving the quality of steel plate coiling.

[0033] Working principle: The galvanized steel sheet passes between the lower leveling roller 7 and the upper leveling roller 8, through the two integrated frames 6, and connects to the take-up roller 4. The second hydraulic cylinder 15 drives the second push arm 16 to move. The second push arm 16 drives the linkage arm 18 to rotate around the hinge shaft 14 via the linkage shaft 17. The linkage arm 18 drives the pressure roller 5 to rotate, so that the pressure roller 5 contacts the surface of the galvanized steel sheet. The pressure roller 5 presses and limits the galvanized steel sheet. The drive mechanism 12 drives the take-up roller 4 to rotate, and the take-up roller 4 winds up the steel sheet. As the diameter of the steel coil gradually increases, the second hydraulic cylinder 15 also works synchronously to drive the second push arm 16 to gradually retract, which in turn drives the pressure roller 5 to gradually move, so as to better adapt to steel coils of different diameters. During the winding process, in order to avoid displacement of the steel sheet and improve the accuracy of winding, the servo motor 20 drives the bidirectional lead screw 21 to rotate. In the process of coiling, under the sliding cooperation of the integrated frame 6 and the roller frame 2, the two sets of threaded sleeves 22 are driven by the double screw 21 to move closer to each other. The threaded sleeves 22 drive the integrated frame 6 and the limiting wheel 19 to move closer to each other and make the limiting wheel 19 contact the two sides of the steel plate to center and clamp the steel plate to prevent it from deviating. At the same time, in order to ensure the flatness of the steel plate during the coiling process, the first hydraulic cylinder 9 drives the first push arm 10 to move during the movement of the steel plate. The first push arm 10 drives the lower pressure block 11 to move downward, and the lower pressure block 11 drives the upper leveling roller 8 to move downward, so that the upper leveling roller 8 contacts the upper surface of the steel plate and the lower leveling roller 7 contacts the lower surface of the steel plate. Under the staggered contact of the upper leveling roller 8 and the lower leveling roller 7, the steel plate is rolled flat to improve the flatness of the steel plate and thus improve the quality of the steel plate coiling. The above is the complete usage of the coiling machine for galvanized steel coil production.
