Description

Technical Field

[0001] This utility model relates to the field of uncoiler technology, specifically to an uncoiler equipped with a bidirectional leveling structure. Background Technology

[0002] Uncoiling machines are specialized equipment for metal sheet leveling lines. They are used to place metal coils to be processed and feed them to the next process. They can be combined into uncoiling, leveling, and shearing production lines and other metal sheet processing production lines according to relevant processing requirements.

[0003] Metal sheets unwound by the uncoiler must be leveled by a leveling device. Existing uncoilers do not have a leveling function; instead, the metal sheet is unwound and then fed into the leveling device for leveling. Because the two processes are performed separately, the workload increases, and multiple devices increase the space occupied. To address this, we propose an uncoiler with a bidirectional leveling structure. Utility Model Content

[0004] This utility model provides an uncoiling machine with a bidirectional leveling structure, which has the advantage that the metal coil unwound from the uncoiling mechanism directly enters the extrusion gap, so that the metal plate is leveled, thus solving the problems mentioned in the background art.

Several lower pressure rollers are rotatably mounted on the top of the lower frame. A middle frame is parallel to the lower frame, and several upper pressure rollers, staggered with the lower pressure rollers, are rotatably mounted below the middle frame. A lifting mechanism connected to the middle frame is located on the top of the support frame, allowing the lifting mechanism to move the upper pressure rollers above the lower pressure rollers. A compression gap is provided between the two, and the metal coil unwound from the uncoiling mechanism enters the compression gap. The lower pressure rollers are driven to rotate by a drive device, causing the lower pressure rollers to move the metal coils within the compression gap.

[0007] Preferably, an upper drive roller is rotatably mounted at the bottom of the middle frame near the unwinding mechanism, and a lower drive roller is rotatably mounted at the top of the lower frame near the unwinding mechanism. The lower drive roller is located directly below the upper drive roller, clamps the metal coil of the upper drive roller, and is driven to rotate by a drive device.

[0008] Preferably, the driving device includes a first driving motor disposed on the bottom support frame below the lower frame, and a second transmission wheel is respectively provided on the shaft of the first driving motor and at one end of the lower pressure roller and the lower transmission roller, and the second transmission wheels are connected to each other by a transmission belt.

[0009] Preferably, the lifting mechanism includes a top frame installed on the top of the bracket, and a second telescopic mechanism is installed vertically downward in the middle of the top frame, and the second telescopic mechanism is vertically connected to the middle of the middle frame.

[0010] The four corners of the central frame are respectively placed on the bracket, and the four corners of the central frame are respectively connected to the support rails by sliders. The support rails are respectively set on the side of the bracket.

[0011] Preferably, the unwinding mechanism includes a base, and a support sleeve is rotatably disposed inside the top of the base, the support sleeve being parallel to one side of the extrusion gap;

[0012] A drive shaft is rotatably mounted inside the support sleeve. The end of the drive shaft near the extrusion gap extends to the outside of the support sleeve. The end surface of the drive shaft has an external thread. An annular seat is coaxially mounted on the end of the drive shaft. The inner surface of the annular seat has an internal thread that matches the external thread. The annular seat is threadedly connected to the end of the drive shaft. Multiple arc-shaped plates are arranged parallel and symmetrically on the outside of the support sleeve. At least two inclined drive arms are rotatably connected to the side of the arc-shaped plates near the support sleeve. The drive arms are arranged parallel to each other. The ends of the drive arms away from the arc-shaped plates are rotatably connected to the surfaces of the annular seat and the support sleeve, respectively. The end of the support sleeve away from the annular seat is connected to a second drive motor through a flange. The shaft of the second drive motor is connected to the end of the drive shaft.

[0013] The end of the support sleeve furthest from the annular seat is also connected to the drive mechanism.

[0014] Preferably, the drive mechanism includes a third drive motor mounted on the base, with first transmission wheels mounted on both the shaft of the third drive motor and the support sleeve, and the two first transmission wheels connected by a conveyor belt; the end of the support sleeve away from the annular seat is rotatably mounted inside the top of the support seat, and the bottom of the support seat is fixed to the base.

The other end of the first telescopic mechanism is inclined downward and rotatably connected to the side of the base.

[0018] Compared with the prior art, in use, the metal coil unwound from the uncoiling mechanism enters the extrusion gap. The lower pressure roller pushes the deformed metal plate upward, while the lower pressure roller pushes the deformed metal plate downward. The metal plate moving in the extrusion gap moves continuously up and down in both directions, thereby destroying the original residual curling stress along the longitudinal direction of the metal plate, so that the metal plate is flattened. Moreover, the gap between the upper and lower pressure rollers can be adjusted by extending and retracting the second telescopic mechanism, making the operation simple and convenient.

Detailed Implementation

[0026] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Reference Figures 1 to 5 This utility model provides a technical solution: an uncoiling machine with a bidirectional leveling structure, including an uncoiling mechanism, which is set on a bottom support frame 1. The uncoiling mechanism includes a base 7, and a support sleeve 29 is rotatably mounted inside the top of the base 7. A drive shaft 26 is rotatably mounted inside the support sleeve 29, wherein both ends of the support sleeve 29 are respectively connected to the drive shaft 26 through bearings. One end of the drive shaft 26 extends to the outside of the support sleeve 29. An annular seat 31 is coaxially mounted on the end of the drive shaft 26. The annular seat 31 is threaded to the end of the drive shaft 26, that is, an external thread is provided on the end surface of the drive shaft 26, and an internal thread matching the external thread is provided on the inner surface of the annular seat 31.

[0028] Multiple arc-shaped plates 12 are arranged parallel and symmetrically on the outside of the support sleeve 29. Figure 4 The central section comprises four symmetrically distributed arc-shaped plates 12. At least two inclined drive arms 30 are rotatably connected to each arc-shaped plate 12 on the side closest to the support sleeve 29. Each arc-shaped plate requires only two drive arms 30, which must be arranged parallel to each other. Figure 5 As shown, the end of the drive arm 30 away from the arc plate 12 is rotatably connected to the surfaces of the annular seat 31 and the support sleeve 29, respectively.

[0029] The end of the support sleeve 29 furthest from the annular seat 31 is connected to a flange (e.g. Figure 5 The location indicated by the middle arrow A) is connected to the second drive motor 22. The rotating shaft of the second drive motor 22 is connected to the end of the transmission shaft 26, enabling the second drive motor 22 to drive the transmission shaft 26 to rotate within the support sleeve 29. Figure 5 As shown, when the second drive motor 22 drives the transmission shaft 26 to rotate, the transmission shaft 26 can drive the ring seat 31 to reciprocate along its axial direction, so that the ring seat 31 moves closer to the support sleeve 29 or away from the support sleeve 29. When the ring seat 31 moves closer to the support sleeve 29, the ring seat 31 can drive the drive arm 30 to lift upward, so that the arc plate 12 is spread outward. When the ring seat 31 moves away from the support sleeve 29, it will drive the drive arm 30 to move horizontally, so that the arc plate 12 is retracted inward.

[0030] like Figure 1As shown, in use, the metal coil is placed on the arc-shaped plate 12, and under the drive of the second drive motor 22, the arc-shaped plate 12 unfolds simultaneously to support the inside of the metal coil. Figure 1 and Figure 4 As shown, a support 5 is installed on one side of the base 7. A drive shaft 3 is rotatably installed inside the support 5. The drive shaft 3 is parallel to the transmission shaft 26. An arc-shaped pressure arm 8 is connected to the end of the drive shaft 3 away from the support 5. A pressure roller 9 is rotatably installed at the end of the arc-shaped pressure arm 8, and the pressure roller 9 is positioned above the metal coil. A connecting rod 4 is installed at the end of the drive shaft 3 near the support 5. A first telescopic mechanism 2 is rotatably installed at the end of the connecting rod 4. The other end of the first telescopic mechanism 2 is inclined downward and rotatably connected to the side of the base 7.

[0031] The first telescopic mechanism 2 is a cylinder. The cylinder drives the drive shaft 3 to rotate through the connecting rod 4, which allows the arc-shaped pressure arm 8 to rotate. In use, the arc-shaped pressure arm 8 is positioned on top of the metal coil, that is, the pressure roller 9 presses the free end of the metal coil to prevent the free end of the metal coil from suddenly loosening.

[0032] In actual use, the support sleeve 29 needs to rotate, thereby driving the arc plate 12 to rotate and gradually unfold the metal coil. The end of the support sleeve 29 away from the annular seat 31 is also connected to the drive mechanism. The drive mechanism includes a third drive motor 24 set on the base 7. The first transmission wheel 28 is installed on the shaft of the third drive motor 24 and on the support sleeve 29. The two first transmission wheels 28 are connected by a conveyor belt. Here, the first transmission wheel 28 is a sprocket and the conveyor belt is a chain.

[0033] To improve the support performance of the support sleeve 29 and make it more stable during rotation, the end of the support sleeve 29 away from the annular seat 31 is rotatably installed inside the top of the support seat 33. The bottom of the support seat 33 is fixed to the machine base 7, so that there are two support points on the support sleeve 29: the support seat 33 and the machine base 7, which makes the support effect of the support sleeve 29 better.

[0034] This application has a leveling mechanism on one side of the unwinding mechanism, and the leveling mechanism will be described in detail below;

[0035] like Figure 1 As shown, the leveling mechanism includes a lower frame 14, the four corners of the lower frame 14 are connected to the bracket 15 respectively, the bottom of the bracket 15 is fixed to the bottom support frame 1, and several pressure rollers 16 are rotatably installed on the top of the lower frame 14.

[0036] A middle frame 18 is parallel to the lower frame 14 above it. Several upper pressure rollers 19, staggered with the lower pressure rollers 16, are rotatably mounted below the middle frame 18. A lifting mechanism connected to the middle frame 18 is located at the top of the support 15. The lifting mechanism includes a top frame 11 mounted on the top of the support 15. A second telescopic mechanism 17 is vertically mounted downwards from the center of the top frame 11. The second telescopic mechanism 17 can be a pneumatic cylinder or a hydraulic cylinder, but a hydraulic cylinder is preferred. The second telescopic mechanism 17 is vertically connected to the center of the middle frame 18. The four corners of the middle frame 18 are positioned on the support 15 and are connected to support rails 10 via sliders. The support rails 10 are located on the sides of the support 15. This allows the middle frame 18 to move up and down via the second telescopic mechanism 17, and the four corners of the middle frame 18 move on the support rails 10, making the middle frame 18 more stable.

[0037] In use, the lifting mechanism moves the upper pressure roller 19 above the lower pressure roller 16, with a compression gap between them. This gap is parallel to one side of the support sleeve 29. The metal coil unwound from the uncoiling mechanism enters the compression gap. The lower pressure roller 16 is driven to rotate by a drive device, causing it to move the metal coil within the compression gap. During use, the lower pressure roller 16 lifts the deformed metal plate upwards and downwards. The metal plate moving within the compression gap continuously moves up and down in both directions, thereby breaking down the original residual curling stress along the longitudinal direction of the metal plate, thus flattening it. It should be noted that the gap between the upper pressure roller 19 and the lower pressure roller 16 can be adjusted by extending and retracting the second telescopic mechanism 17, which is very convenient.

[0038] Furthermore, in order to ensure that the metal plate can move forward stably, such as Figure 3 As shown, an upper drive roller 23 is rotatably mounted at the bottom of the middle frame 18 near the unwinding mechanism, and a lower drive roller 25 is rotatably mounted at the top of the lower frame 14 near the unwinding mechanism. The lower drive roller 25 is located directly below the upper drive roller 23. The lower drive roller 25 clamps the metal coil of the upper drive roller 23 and is driven to rotate by the drive device.

[0039] The driving device includes a first drive motor 21 mounted on the bottom support frame 1 below the lower frame 14. Second transmission wheels 32 are respectively mounted on the shaft of the first drive motor 21 and at one end of the lower pressure roller 16 and the lower transmission roller 25. The second transmission wheels 32 are connected by a transmission belt. Here, the second transmission wheel 32 is a sprocket and the transmission belt is a transmission chain.

[0040] Furthermore, a limiting plate 20 is provided on the side of the arc plate 12 near the base 7. The limiting plate 20 is coaxially mounted on the support sleeve 29. The limiting plate 20 can limit the metal coil on the arc plate 12.

[0041] Furthermore, during operation, the second drive motor 22 needs to rotate continuously, so the second drive motor 22 needs to be controlled during rotation. Therefore, this application also includes an energized slip ring 27. The rotor of the energized slip ring 27 is connected to the second drive motor 22 by a wire. The rotor is coaxially mounted on the support sleeve 29. The stator of the energized slip ring 27 is mounted on the support base 33, and the stator and rotor are in sliding contact.

[0042] Based on the above embodiments, further optimizations can be made, such as... Figure 1 and Figure 4 As shown, a control cabinet 13 is installed on the bracket 15. The control cabinet 13 contains a controller, which is a PLC logic controller or a host. The controller is connected to the first telescopic mechanism 2, the second telescopic mechanism 17, the first drive motor 21, the third drive motor 24, the energized slip ring 27, and the first transmission wheel 28, thereby realizing automatic control. In addition, a control panel and operation buttons are provided on the surface of the control cabinet 13.

[0043] Based on the above embodiments, further optimization can be achieved by installing a sealing cover 6 on the base 7, which covers the second drive motor and the third drive motor 24.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
