Description

Technical Field

[0001] This utility model relates to the field of steel strip processing technology, and in particular to a steel strip uncoiling and straightening device. Background Technology

[0002] An uncoiler, also known as a coil unwinder, is one of the auxiliary equipment on a cold rolling mill or cold processing production line for steel plates (strips). Its function is to open the steel strip coil and draw out the end of the rolled piece so that it can enter the continuous operation unit.

[0003] Chinese Patent Application Publication No. CN219188191U discloses a steel strip uncoiling and straightening machine, including an uncoiling device and a straightening device. The uncoiling device includes an uncoiling main unit, a roll assembly, and a first pressure roller assembly. The roll assembly is rotatably mounted on the uncoiling main unit, and the first pressure roller assembly is hinged to the uncoiling main unit. The roll assembly is used to fix the steel strip roll, and the first pressure roller assembly is used to roll the steel strip roll on the roll assembly. The straightening device includes a straightening main unit and a second pressure roller assembly hinged to the straightening main unit. The straightening main unit has a straightening inlet, and the second pressure roller assembly is used to adjust the angle at which the steel strip enters the straightening inlet. When the outer ring of the steel strip roll on the roll assembly enters the straightening inlet, the first pressure roller assembly rolls the steel strip to make it enter the straightening inlet smoothly. At the same time, the second pressure roller assembly adjusts the angle at which the steel strip enters the straightening inlet to prevent the steel strip from warping and affecting the uncoiling efficiency, thereby ensuring the production quality of the steel strip and improving production efficiency.

[0004] However, the above-mentioned steel strip uncoiling and straightening machine does not have a guide structure installed. During the straightening process, due to the squeezing action of the pressure rollers and the elastic deformation of the steel strip itself, the edge of the steel strip may move irregularly in the transverse direction. This displacement may gradually accumulate, causing the overall position of the steel strip after straightening to deviate significantly from the initial position, or even exceed the processing range of subsequent processing equipment, which can easily reduce the quality of the steel strip.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1-4A steel strip uncoiling and straightening device includes a base 1, an uncoiling mechanism on the top of the base 1, a bearing plate 5 fixedly mounted on the top of the base 1, a conveying mechanism on the top of the bearing plate 5, a pressing mechanism on the top of the bearing plate 5, and a driving mechanism on the top of the bearing plate 5. A screw 22, a bidirectional threaded rod, is mounted on the top of the bearing plate 5 via the driving mechanism. The screw 22 is made of stainless steel to ensure higher structural strength and durability. The driving mechanism includes a fixed plate 17 on the top of the bearing plate 5. A second motor 18 is fixedly mounted on the left side of the fixed plate 17. A second rotating shaft 19 is fixedly mounted on the output end of the second motor 18. A third bevel gear 20 is fixedly mounted on the surface of the second rotating shaft 19. A fourth bevel gear 21 meshes with the surface of the third bevel gear 20 and is fixedly connected to the screw 22. The driving mechanism provides driving force for the rotation of the screw 22, allowing it to rotate simultaneously. The distance between the guide wheels 25 can be adjusted simultaneously. A frame 23 is rotatably connected to the surface of the screw 22, and the frame 23 is fixedly connected to the bearing plate 5. A movable plate 24 is threadedly connected to the surface of the screw 22, and the movable plate 24 is slidably connected to the frame 23. Guide wheels 25 are rotatably connected to the top of the movable plate 24. There are multiple sets of guide wheels 25, and the multiple sets of guide wheels 25 are symmetrically distributed. In this steel strip uncoiling and straightening device, during the uncoiling mechanism uncoiling the steel strip and the straightening process of the steel strip through the conveying mechanism and the extrusion mechanism, the guide wheels 25 can guide the steel strip, effectively limiting the lateral movement of the steel strip edge and ensuring that the steel strip always stays on the predetermined path during the straightening process. The drive mechanism can make the screw 22 rotate, causing the movable plate 24 to move relative to each other along the frame 23, and causing the guide wheels 25 to move relative to each other, adjusting the distance between the guide wheels 25, so that the guide wheels 25 can be better adapted to guide steel strips of different widths, improving the practicality of the device.

[0022] according to Figure 2 As shown, the uncoiling mechanism includes an uncoiling host 2, a roll assembly 3, and a pressure roller assembly 4. The uncoiling host 2 is fixedly installed on the top of the base 1. The roll assembly 3 is rotatably installed on the uncoiling host 2. The pressure roller assembly 4 is hinged to the uncoiling host 2. The roll assembly 3 is used to fix the steel strip roll, while the uncoiling host 2 causes the pressure roller assembly 4 to flip, so that the pressure roller assembly 4 contacts the steel strip roll and can roll it. The uncoiling host 2 causes the roll assembly 3 to rotate, which facilitates the uncoiling of the steel strip roll.

[0023] according to Figure 3As shown, the conveying mechanism includes a support plate 6 mounted on the top of the bearing plate 5, a mounting frame 7 fixedly mounted on the side of the support plate 6, a first motor 8 fixedly mounted on the right side of the mounting frame 7, a first rotating shaft 9 fixedly mounted on the output end of the first motor 8, a first bevel gear 10 fixedly mounted on the surface of the first rotating shaft 9, a second bevel gear 11 meshing with the surface of the first bevel gear 10, a conveying roller 12 fixedly mounted inside the second bevel gear 11, and the conveying roller 12 rotatably connected to the support plate 6. The extrusion mechanism includes a support frame 13 mounted on the top of the bearing plate 5, a hydraulic push rod 14 fixedly mounted on the top of the support frame 13, a movable frame 15 fixedly mounted on the output end of the hydraulic push rod 14, and an extrusion roller 16 rotatably connected inside the movable frame 15. The extrusion mechanism facilitates the extrusion of the steel strip and, in conjunction with the conveying mechanism, facilitates the conveying of the steel strip, thereby facilitating the straightening of the steel strip.

[0024] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0025] In use: the drum assembly 3 is used to fix the steel strip coil, while the uncoiling host 2 causes the pressure roller assembly 4 to rotate, so that the pressure roller assembly 4 contacts the steel strip coil and rolls it. The second motor 18 causes the second rotating shaft 19 to rotate, which in turn causes the third bevel gear 20 to rotate, the fourth bevel gear 21 to rotate, and the screw 22 to rotate. This causes the moving plate 24 to move relative to each other along the frame 23, and the guide wheels 25 to move relative to each other, adjusting the distance between the guide wheels 25. Then, the uncoiling host 2 rotates the drum assembly 3, which allows the steel strip coil to be rolled. Unwinding allows the steel strip coil to enter between the conveyor roller 12 and the extrusion roller 16 along the guide wheel 25. The hydraulic push rod 14 causes the movable frame 15 to move downward, which in turn causes the extrusion roller 16 to move downward and extrude the steel strip. At the same time, the first motor 8 causes the first rotating shaft 9 to rotate, which in turn causes the first bevel gear 10 to rotate, which in turn causes the second bevel gear 11 to rotate, which in turn causes the conveyor roller 12 to rotate, causing the steel strip to move to the right. This, combined with the extrusion roller 16, completes the straightening of the steel strip. During the straightening process, the guide wheel 25 guides the steel strip.
