Description

Technical Field

[0001] This application relates to the technical field of steel plate production, and more particularly to a steel plate coil leveling equipment. Background Technology

[0002] A slitting machine is a machine used to perform a series of processing operations such as uncoiling, leveling, and shearing of rolled materials (steel coils, aluminum coils, and other metal sheets).

[0003] During the unwinding process of the coil, the sheet material can be gradually output. However, since the diameter of the coil gradually decreases during unwinding, the amount of sheet material output by coils of different diameters is inconsistent at the same rotation speed. The output amount of sheet material directly affects the tension of the sheet material by the subsequent conveying mechanism. Therefore, in order to adapt to the subsequent leveling output operation, the rotation speed of the coil needs to be adjusted in real time.

[0004] Current leveling equipment typically uses servo motors and various sensors to detect the output of the sheet material in real time and precisely adjust the speed of the roll. This method has high costs and electronic components are prone to failure, so there is an urgent need to develop a high-stability and low-cost roll leveling equipment. Summary of the Invention

[0006] Therefore, one objective of this application is to provide a steel plate rolling and leveling device that, with the help of an adjustment component, allows direct control of the rolling speed to ensure that the output of the rolling plate is precisely matched with its own diameter, thereby achieving stable and efficient output of the plate. This design adopts a mechanical transmission method, which is low in cost and has high operational stability.

[0007] To achieve the above objectives, a first aspect of this application provides a steel plate coil leveling device, comprising a frame, a conveying mechanism, and an uncoiling mechanism. The frame includes a base, two first frames, and second frames. The two first frames are mounted on the base via a relative moving member. One of the first frames is connected to an extension frame.

[0008] In addition, the steel plate coil leveling equipment proposed in this application may also have the following additional technical features: In one embodiment of this application, the linear moving member includes a drive shaft, a lead screw, and a linkage seat. The drive shaft and the lead screw are parallel and movably mounted on the extension frame. One end of the drive shaft is provided with a first drive source, and one end of the lead screw is provided with a second drive source. Multiple limiting rails are circumferentially distributed on the outer side of the drive shaft, and the drive wheel is slidably sleeved on the outer side of the multiple limiting rails.

[0018] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0019] The following description, in conjunction with the accompanying drawings, describes a steel plate coil leveling device according to an embodiment of this application, which can be applied to leveling operations of coils made of materials such as steel and aluminum.

[0020] like Figures 1-5 As shown, the steel plate coil leveling equipment of this application embodiment may include a frame 10, a conveying mechanism (not shown in the figure) and an unwinding mechanism 30.

[0021] The frame 10 may include a base 11, two first frames 12, and a second frame 13. The two first frames 12 are mounted on the base 11 via relative moving parts 50, and an extension frame 14 is connected to one of the first frames 12. The two second frames 13 are fixedly mounted on the base 11.

[0022] It should be noted that the relative moving component 50 described in this embodiment has the function of controlling the two first frames 12 to move closer or further apart. The relative moving component 50 may include a first motor 51 and a bidirectional screw 52. The two ends of the bidirectional screw 52 have opposite helical directions, and the two first frames 12 are respectively threaded onto the two ends of the bidirectional screw 52. One end of the bidirectional screw 52 is connected to the output end of the first motor 51, and the other end is movably connected to the base 11. The bidirectional screw 52 is horizontally set, and it can rotate forward or reverse after being driven by the first motor 51. When rotating forward, the two first frames 12 can move closer together; when rotating in reverse, the two first frames 12 can move further apart.

[0023] The conveying mechanism may include multiple roller groups 21 arranged sequentially from left to right. Each roller group 21 may include two rotating rollers 211, one above the other, and each rotating roller 211 is movably mounted on two second frames 13. The second frames 13 are inclined towards the side facing the first frame 12, and the multiple roller groups 21 are arranged along the direction of the first frame 12. Each rotating roller 211 has a gear 22 at one end, and the two corresponding gears 22 mesh with each other. One of the gears 22 is equipped with a second motor 23. In one roller group 21, the second motor 23 can directly drive the connected gear 22 to rotate. Based on the meshing transmission relationship between the gears 22, the other gear 22 will rotate synchronously and in the opposite direction. In this way, the two rotating rollers 211 work together to smoothly convey the steel plate away from the first frame 12. Moreover, by precisely adjusting the multiple corresponding second motors 23, the rotation speed of the multiple roller groups 21 can be kept highly consistent, thereby achieving stable and efficient conveying of the steel plate.

[0024] It should be noted that the conveying mechanism described in this embodiment can convey the uncoiled steel plate. During the conveying process, the mechanism can also perform a certain degree of flattening operation on the steel plate, effectively improving the flatness of the steel plate and providing convenience for subsequent processing.

[0025] The unwinding mechanism 30 may include a control component 31 and two clamping parts 32, wherein the two clamping parts 32 are respectively movably disposed on the corresponding first frame 12. Each clamping part 32 may include a mandrel 321 and a sealing ring 322, wherein the sealing ring 322 is fixedly sleeved on the outside of the mandrel 321 and is used to clamp the steel plate coil. One end of the mandrel 321 movably passes through the corresponding first frame 12, and the mandrel 321 is connected to the drive ring.

[0026] The control assembly 31 may include two synchronous pulleys 311, a synchronous belt 312, a conical pulley 313, a drive wheel 314, and a linear moving member 315. The two synchronous pulleys 311 are located in the same vertical plane and are respectively connected to the extension frame 14 and the corresponding clamping part 32 (mandrel 321). The synchronous belt 312 is sleeved on the outside of the two synchronous pulleys 311. The conical pulley 313 is movably mounted on the extension frame 14, with one end connected to the corresponding synchronous pulley 311. The drive wheel 314 is movably mounted on the extension frame 14 via the linear moving member 315, and the drive wheel 314 is in close contact with the outside of the conical pulley 313.

[0027] It should be noted that the linear moving component 315 described in this embodiment has the function of controlling the drive wheel 314 to move linearly. During the movement, the drive wheel 314 can always be in close contact with the outer wall of the conical wheel 313. As the drive wheel 314 moves, it will successively contact different diameter parts on the conical wheel 313. Due to the unique shape characteristics of the conical wheel 313, when the rotational speed of the drive wheel 314 remains constant, the movement of its position will cause the rotational speed of the conical wheel 313 to change accordingly. Specifically, when the drive wheel 314 gradually moves from the large diameter side of the conical wheel 313 to the small diameter side, the rotational speed of the conical wheel 313 will gradually increase during the unwinding process of the steel plate coil. Under the synergistic action of the synchronous belt 312 and the two synchronous pulleys 311, the corresponding mandrel 321 can drive the steel plate coil to rotate, and the rotational speed gradually increases. This design cleverly adapts to the situation where the diameter of the steel plate coil continuously decreases during the gradual unwinding process, thereby ensuring that the steel plate can be unwound at a uniform speed, providing a strong guarantee for the stability of the production process.

[0028] It should be noted that the control component 31 described in this embodiment has the function of controlling the rotation of the clamping part 32 connected thereto. Under the action of the control component 31, the rotation speed of the clamping part 32 will gradually increase. This dynamic adjustment of the rotation speed can ensure that the unwinding process of the steel plate coil is more uniform and effectively avoid production problems caused by uneven unwinding.

[0029] The linear moving part 315 may include a drive shaft 3151, a lead screw 3152, and a linkage seat 3153. The drive shaft 3151 and the lead screw 3152 are parallel and are respectively movably mounted on the extension frame 14. One end of the drive shaft 3151 is provided with a first drive source 41, and one end of the lead screw 3152 is provided with a second drive source 42. The drive wheel 314 is driven to rotate by the drive shaft 3151, and the drive shaft 3151 is driven by the first drive source 41. Multiple limiting rails 31511 are distributed circumferentially on the outer side of the drive shaft 3151. The drive wheel 314 is slidably sleeved on the outer side of the multiple limiting rails 31511. The two ends of the linkage seat 3153 are respectively movably sleeved on the outer side of the lead screw 3152 and the outer side of the drive shaft 3151. One end of the linkage seat 3153 is provided with two support arms 31531, which are located on both sides of the drive wheel 314. Each support arm 31531 is slidably attached to the drive wheel 314. The support arm 31531 is provided with a through hole 315311, which is located on the outer side of the multiple limiting rails 31511. The limiting rails 31511 are attached to the inner wall of the through hole 315311. The other end of the linkage seat 3153 is provided with a structure that cooperates with the lead screw 3152, which can achieve a precise cooperation with the lead screw 3152. Drawing on the transmission mechanism of ball screw 3152, when screw 3152 rotates around its own axis, linkage seat 3153 will make precise and corresponding linear displacement along the axial direction of screw 3152 under the action of the screw pair.

[0030] The limiting rail 31511 described in this embodiment enables the drive shaft 3151 and drive wheel 314 to have a self-locking function in the rotation direction, which can ensure that the two always rotate synchronously during the movement. At the same time, under the drive of the linkage seat 3153, the drive wheel 314 can achieve linear sliding on the outside of the drive shaft 3151.

[0031] It should be noted that the first drive source 41 and the second drive source 42 described in this embodiment can both be servo motors, geared motors, etc., wherein the second drive source 42 has the ability to control the rotation of the lead screw 3152 connected to it. When the lead screw 3152 rotates, it will drive the linkage seat 3153 to move, and the linkage seat 3153 will in turn drive the drive wheel 314 to slide linearly on the outside of the drive shaft 3151, thereby achieving precise control of the position of the drive wheel 314.

[0032] Specifically, when leveling the coil 60 is required, personnel first use lifting tools to place the coil 60 in a suitable position between the two clamping parts 32. Then, the two first frames 12 are moved synchronously in a similar direction by the relative moving parts 50, so that the mandrels 321 on both sides are accurately inserted into the middle of the coil 60. When the sealing plates on both sides are tightly abutted against the sides of the coil 60, the two first frames 12 are stopped moving, thus achieving stable clamping of the coil 60.

[0033] Subsequently, personnel insert the leading end of the sheet material on the coil 60 between the two rotating rollers 211. Then, the control component 31 drives the connected clamping part 32 to rotate, thereby causing the steel coil to rotate and unwind. During this process, the conveying mechanism works in coordination to ensure smooth conveying of the sheet material. Furthermore, under the precise control of the control component 31, the rotational speed of the corresponding clamping part 32 can be gradually increased, ensuring a uniform and stable unwinding process and guaranteeing the smooth progress of the entire leveling operation.

[0034] In summary, the steel plate rolling and leveling equipment of this application embodiment can directly control the rolling speed with the help of the adjustment component, ensuring that the output of the rolling plate is accurately matched with its own diameter, thereby achieving stable and efficient output of the plate. This design adopts a mechanical transmission method, which is low in cost and has high operational stability.
