Description

Technical Field

[0001] This utility model belongs to the field of uncoiler technology, specifically, it relates to a non-clutch rotary uncoiler for strip steel. Background Technology

[0002] In the traditional strip steel uncoiling process, most uncoilers with clutch devices are used.

[0003] Steel pipe production generally uses steel strip as raw material. During production, the steel strip needs to be unrolled, and then coiled and welded to form steel pipes. Therefore, a large number of steel strip coils need to be unrolled. However, in actual production, since the steel strip ends are usually welded to the steel strip coil, an uncoiler is needed to cut open the steel strip ends in order to unroll the steel strip.

[0004] The uncoiler mainly consists of two parts: a temporary storage unit and an uncoiling unit, which are connected by a guide plate. The temporary storage unit uses a tipping hopper to temporarily store the steel strip coils, while the uncoiling unit uses a power roller assembly and a shovel driven by a hydraulic mechanism. During operation, the steel strip coil can be placed into the tipping hopper by an overhead crane, forklift, etc. The tipping hopper then flips, causing the steel strip coil to roll onto the power roller assembly in the temporary storage unit via the guide plate. Afterward, the power roller assembly in the uncoiling unit drives the steel strip coil to rotate, and the hydraulic mechanism drives the shovel to adhere to the surface of the steel strip coil, shoveling open the steel strip head as the coil rotates.

[0005] However, existing steel strip uncoilers use a clutch to control the rotation of the material tray, switching between active and passive modes. Due to the addition of the clutch, the equipment has a high failure rate.

[0006] In view of this, this utility model is proposed. Utility Model Content

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A clutchless rotary uncoiler for strip steel includes a placement platform and support legs. A placement box and a servo motor are mounted above the placement platform. A rotating rod is fixedly installed at the output end of the servo motor. A pulley is fixedly connected to the end of the rotating rod away from the servo motor, and a conveyor belt is mounted on the pulley. Another pulley is mounted at the other end of the conveyor belt, and a first rotating rod is fixedly installed on the pulley. A first gear is fixedly installed on the first rotating rod, and a second gear meshes with the first gear. A second rotating rod is fixedly installed on the second gear. A mounting plate is fixedly connected to the end of the second rotating rod away from the second gear. A rotating drum is fixedly installed on the mounting plate. A movable plate is located at the other end of the rotating drum. A rotating rod is fixedly installed at the end of the movable plate away from the mounting plate. The end of the rotating rod away from the movable plate is rotatably connected to the support legs. An inspection door is provided on one side of the placement box.

[0009] In a preferred embodiment of the present invention, the first rotating rod and the second rotating rod are respectively provided with a first bearing and a second bearing, and an mounting bracket is fixedly installed above the first bearing and the second bearing, and the other end of the mounting bracket is fixedly connected to the upper part of the inner cavity of the placement box, and the first rotating rod and the second rotating rod respectively movably pass through the placement box.

[0010] In a preferred embodiment of the present invention, a second sliding groove is provided on the rotating drum, and a second slider is slidably installed on the second sliding groove. A second circular sliding groove is provided in the inner cavity of the moving disk, and a second slider is slidably arranged in the inner cavity of the second circular sliding groove.

[0011] In a preferred embodiment of the present invention, a first circular groove is provided at the end of the movable disk away from the mounting disk, and a first slider is slidably installed in the inner cavity of the first circular groove.

[0012] In a preferred embodiment of this utility model, a threaded rod is engaged and penetrated on the support leg, one end of the threaded rod is rotatably connected to the first slider, and the end of the threaded rod away from the first slider is fixedly connected to a handle.

[0013] In a preferred embodiment of this utility model, the diameter of the first gear is smaller than that of the second gear.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] In this invention, the operator controls the servo motor via a controller, which in turn drives the rotating rod to rotate. When the rotating rod rotates, it, with the assistance of a pulley and a conveyor belt, causes the first rotating rod to rotate. This rotation drives the first gear to rotate, and because the first and second gears mesh, they in turn drive the second gear to rotate. Since the diameter of the first gear is smaller than that of the second gear, a speed reduction effect is achieved. When the second gear rotates, it drives the mounting plate to rotate via the second rotating rod, thereby causing the rotating drum to rotate and coil the placed strip steel. The speed reduction achieved through the gear set reduces maintenance costs and equipment failure rates.

[0016] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0024] like Figures 1 to 4As shown, the strip uncoiling rotary uncoiler includes a placement platform 1 and a support leg 3. A placement box 2 and a servo motor 15 are arranged above the placement platform 1. A rotating rod 16 is fixedly installed at the output end of the servo motor 15. A pulley 17 is fixedly connected to the end of the rotating rod 16 away from the servo motor 15, and a transmission belt 18 is arranged on the pulley 17. A pulley 17 is also arranged at the other end of the transmission belt 18, and a first rotating rod 19 is fixedly installed on the pulley 17. A first gear 20 is fixedly installed on the first rotating rod 19. A second gear 21 is meshed on the first gear 20. A second rotating rod 22 is fixedly installed on the second gear 21. A mounting plate 5 is fixedly connected to the end of the second rotating rod 22 away from the second gear 21. A rotating drum 4 is fixedly installed on the mounting plate 5. A movable plate 6 is arranged at the other end of the rotating drum 4. A rotating rod 12 is fixedly installed at the end of the movable plate 6 away from the mounting plate 5. The end of the rotating rod 12 away from the movable plate 6 is rotatably connected to the support leg 3. An inspection door is arranged on one side of the placement box 2. The operator controls the servo motor 15 through the controller, which drives the rotating rod 16 to rotate. When the rotating rod 16 rotates, it can also drive the first rotating rod 19 to rotate with the assistance of the pulley 17 and the conveyor belt 18. When the first rotating rod 19 rotates, it can drive the first gear 20 to rotate. Since the first gear 20 and the second gear 21 mesh with each other, they can drive the second gear 21 to rotate. Because the diameter of the first gear 20 is smaller than the diameter of the second gear 21, it can achieve a speed reduction effect. When the second gear 21 rotates, it can drive the mounting plate 5 to rotate through the second rotating rod 22, thereby driving the rotating drum 4 to rotate and coil the placed strip steel.

[0025] In a specific embodiment, a first bearing 23 and a second bearing 24 are respectively provided on the first rotating rod 19 and the second rotating rod 22. Mounting brackets 25 are fixedly installed above the first bearing 23 and the second bearing 24, with the other end of each mounting bracket 25 fixedly connected to the upper part of the inner cavity of the placement box 2. The first rotating rod 19 and the second rotating rod 22 movably pass through the placement box 2. This design ensures that the first rotating rod 19 and the second rotating rod 22 will not fall off.

[0026] Furthermore, a second sliding groove 11 is provided on the rotating drum 4, and a second slider 14 is slidably mounted on the second sliding groove 11. A second circular sliding groove 13 is provided in the inner cavity of the moving disk 6, and the second slider 14 is slidably disposed in the inner cavity of the second circular sliding groove 13. In this configuration, it is ensured that the moving disk 6 can move horizontally and rotate.

[0027] Furthermore, a first circular groove 7 is provided at the end of the movable disk 6 away from the mounting disk 5, and a first slider 8 is slidably mounted inside the first circular groove 7. In this configuration, the positions of the first circular groove 7 and the first slider 8 are determined.

[0028] Furthermore, a threaded rod 9 is engaged and passed through the support leg 3. One end of the threaded rod 9 is rotatably connected to the first slider 8, and the end of the threaded rod 9 away from the first slider 8 is fixedly connected to a handle 10. In this configuration, the movable disk 6 can move horizontally and rotate.

[0029] Furthermore, the diameter of the first gear 20 is smaller than that of the second gear 21. In this configuration, because the first gear 20 and the second gear 21 mesh with each other, the first gear 20 can drive the second gear 21 to rotate. Since the diameter of the first gear 20 is smaller than that of the second gear 21, it can achieve a speed reduction effect.

[0030] The implementation principle of the non-clutch rotary uncoiler for strip steel uncoiling in this embodiment is as follows:

[0031] First, the worker sets one end of the strip steel onto the rotating drum 4. Once set, the worker rotates the handle 10, causing the threaded rod 9 to rotate and move forward. When the threaded rod 9 rotates and moves forward, it pushes the first slider 8, which in turn drives the moving disc 6 to move horizontally with the assistance of the second circular groove 13, the second groove 11 opened on the rotating drum 4, and the second slider 14. This allows the moving disc 6 to move to the side wall of the strip steel, thus ensuring that the strip steel will not deviate when the rotating drum 4 winds it up.

[0032] When the movable disk 6 is adjusted, the operator controls the servo motor 15 through the controller. The servo motor 15 drives the rotating rod 16 to rotate. When the rotating rod 16 rotates, it can drive the first rotating rod 19 to rotate with the assistance of the pulley 17 and the conveyor belt 18. When the first rotating rod 19 rotates, it can drive the first gear 20 to rotate. Because the first gear 20 and the second gear 21 mesh with each other, they can drive the second gear 21 to rotate. Since the diameter of the first gear 20 is smaller than the diameter of the second gear 21, it can achieve a speed reduction effect. When the second gear 21 rotates, it can drive the mounting disk 5 to rotate through the second rotating rod 22, thereby driving the rotating drum 4 to rotate and coil the placed strip steel.
