Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum coil production technology, specifically to an automatic winding device for an aluminum coil production line. Background Technology
[0002] In the aluminum coil production process, winding is a key subsequent processing step. Its quality directly determines the shape, compactness, and end face neatness of the finished aluminum coil, which in turn has a significant impact on the product's storage, transportation efficiency, and subsequent deep processing performance.
[0003] In the existing technology, at the beginning stage of aluminum coil winding, due to the lack of an efficient and reliable fixing mechanism for the ends of the aluminum plate, the aluminum plate is very prone to warping, slipping, axial displacement or even loosening on the coil, resulting in loose inner rings and irregular coil shape, which seriously affects the overall quality of the coil. Secondly, during the continuous winding process, there is often a lack of real-time monitoring and automatic correction functions for strip deviation, making it impossible to accurately align and control the edge position of the aluminum plate, resulting in uneven winding end faces, which not only reduces the product grade but may also cause quality defects such as scratches. In addition, the unloading process after winding up the aluminum coils relies heavily on manual operation, which is labor-intensive, inefficient, and poses a high safety risk when handling heavy aluminum coils. Utility Model Content
[0004] The purpose of this invention is to provide an automatic winding device for an aluminum coil production line to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic winding device for an aluminum coil production line, comprising a fixed frame, on which a tensioning coil is mounted via bearings, wherein the tensioning coil can be an existing mechanically or hydraulically tensioning coil product; a winding motor is mounted on the fixed frame and is connected to the tensioning coil for transmission; a retaining edge is provided on the surface of the tensioning coil, and a slot is formed between the retaining edge and the surface of the tensioning coil; two sets of pressure rollers are symmetrically arranged above the tensioning coil; a mounting plate is provided at the top of the fixed frame; a lifting adjustment structure is provided between the pressure rollers and the mounting plate; an edge detection camera is provided behind the pressure rollers; a moving adjustment structure is provided between the edge detection camera and the mounting plate; and an aluminum plate limiting structure is provided behind the edge detection camera.
[0006] The present invention is further configured such that a push plate is non-contactly sleeved on one end of the tensioning roll connecting fixing frame, and a material unloading push assembly is provided on the fixing frame in conjunction with the push plate. After the aluminum plate is wound up, the unloading of the wound aluminum roll on the tensioning roll can be achieved by controlling the movement of the push plate.
[0007] The present invention is further configured such that the unloading pushing assembly includes a pushing frame, the fixed frame has a through groove, the inner end of the pushing frame slides through the through groove and is symmetrically connected to the pushing plate, and the outer end of the pushing frame is connected to a pushing control structure. The through groove allows the pushing frame to slide on the fixed frame, and the pushing frame can then cooperate with the pushing control structure to drive the movement of the pushing plate.
[0008] The present invention is further configured such that the push control structure includes a drive seat, which is installed on the side of the fixed frame away from the tensioning coil. A second ball screw is mounted on the drive seat via a bearing, and a second screw nut and a second screw motor are provided in conjunction with the second ball screw. The tail end of the push frame is connected to the top end of the second screw nut. When the second screw motor is started, the operation of the second ball screw is controlled by the second screw motor, so that the second screw nut can drive the push frame to move horizontally. The push frame can control the movement of the push plate, thereby realizing the push unloading of the wound aluminum coil and improving the convenience of unloading.
[0009] The present invention is further configured such that the lifting and adjusting structure includes a first electric push rod, a pressure detector is provided at the bottom end of the first electric push rod, and a mounting frame is installed at the bottom end of the pressure detector. The pressing roller is symmetrically installed at the bottom end of the mounting frame through bearings. Activating the first electric push rod controls the lifting and lowering of the mounting frame, which in turn controls the lifting and lowering of the pressing roller. The lifting and lowering of the pressing roller enables the aluminum sheet to be pressed during winding, improving the compactness of the aluminum coil after winding. The pressure detector uses an existing pressure sensor product, which can detect the pressure of the pressing roller during pressing in a timely manner, avoiding over-pressuring or insufficient pressing force.
[0010] The present invention is further configured such that the movable adjustment structure includes a first ball screw, which is mounted on the bottom end of the mounting plate through the cooperation of a bearing seat and a bearing. A first screw nut and a first screw motor are mounted on the first ball screw. The edge detection camera is mounted on the bottom end of the first screw nut. When the first screw motor is started, the operation of the first ball screw can be controlled by the first screw motor, thereby enabling the first screw nut to drive the edge detection camera to move horizontally. This allows for flexible adjustment of the detected edge position according to the different widths of the wound aluminum sheet, improving adaptability to use.
[0011] The present invention is further configured such that the aluminum plate limiting structure includes an inner limiting plate and an outer limiting plate, and a second electric push rod is provided on the fixing frame. The output end of the second electric push rod is provided with a mounting shaft. The inner limiting plate and the outer limiting plate are both mounted on the corresponding mounting shaft through bearings. By controlling the extension and retraction of the second electric push rod, the extension and retraction of the corresponding mounting shaft can be controlled, thereby controlling the extension and retraction of the corresponding inner limiting plate and the outer limiting plate. This allows for edge limiting of the aluminum plate during winding, enabling flexible fine-tuning of the aluminum plate winding and improving the accuracy and stability of the edge alignment during winding.
[0012] The present invention is further configured such that a limiting telescopic rod is provided between the mounting frame and the mounting top plate. The limiting telescopic rod is located on both sides of the first electric push rod and extends and retracts synchronously with the first electric push rod. By setting the limiting telescopic rod, the load of the first electric push rod can be shared, thereby improving the stability of the first electric push rod when controlling the movement of the mounting frame and the stability of the pressing roller when pressing the coiled aluminum plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. Improved winding stability and tightness: This utility model achieves initial positioning of the aluminum plate during winding by using the retaining edge and slot on the surface of the tensioning roller, preventing the aluminum plate from warping, slipping, or shifting during winding. The two sets of upper pressure rollers, in conjunction with the lifting and adjusting structure, can precisely control the height through the first electric push rod. The pressure detector provides real-time feedback on the clamping force to prevent over-pressure or insufficient pressure. Furthermore, the tensioning roller expands after winding, enhancing the fit with the aluminum coil and significantly improving the tightness and overall stability of the aluminum coil after winding.
[0014] 2. Ensuring Edge Accuracy and Adaptability During Winding: The edge detection camera is equipped with a movable adjustment structure. The first lead screw motor can drive the camera to move horizontally, adapting to the edge monitoring needs of aluminum plates of different widths. When an aluminum plate offset is detected, the second electric push rod can control the extension and retraction of the inner and outer limit plates to correct the deviation. In this invention, both the inner and outer limit plates are installed via bearings, forming rolling friction with the aluminum plate to reduce wear, effectively ensuring the edge alignment of the aluminum plate during winding and improving winding accuracy. 3. Improved unloading convenience and efficiency: This invention features a push plate fitted onto one end of the tensioning reel, working in conjunction with the unloading push assembly. A second lead screw motor drives a second ball screw, which in turn moves the push frame and push plate. After winding, the tensioning reel retracts, releasing the pressure on the aluminum coil. The pressure roller moves upward and resets, and the push plate automatically pushes the aluminum coil off the tensioning reel without manual disassembly, significantly reducing manual labor intensity and improving unloading efficiency and convenience.

[0023] Please see Figures 1-7 As one implementation of the movable adjustment structure: the movable adjustment structure includes a first ball screw 19, which is installed at the bottom of the mounting top plate 7 through the cooperation of a bearing seat and a bearing. A first screw nut 20 and a first screw motor 21 are installed on the first ball screw 19. An edge detection camera 8 is installed at the bottom of the first screw nut 20.

This allows for flexible adjustment of the detected edge position according to the different widths of the wound aluminum sheet, improving adaptability. When performing edge detection, the edge detection camera 8 can feed back the detection data to the PLC control system, and the PLC control system can adjust the aluminum sheet limit structure.
[0024] Please see Figures 1-7 As one implementation of the aluminum plate limiting structure: the aluminum plate limiting structure includes an inner limiting plate 22 and an outer limiting plate 23. A second electric push rod 24 is provided on the fixing frame 1. The output end of the second electric push rod 24 is provided with a mounting shaft 25. The inner limiting plate 22 and the outer limiting plate 23 are both mounted on the corresponding mounting shaft 25 through bearings. The extension and retraction of the second electric push rod 24 can be controlled according to the data fed back by the edge detection camera 8. By controlling the extension and retraction of the second electric push rod 24, the extension and retraction of the corresponding mounting shaft 25 can be controlled, thereby controlling the extension and retraction of the corresponding inner limiting plate 22 and the outer limiting plate 23. In this way, the edge of the aluminum plate can be limited during winding. In this way, the winding situation of the aluminum plate can be flexibly fine-tuned, improving the accuracy and stability of the aluminum plate winding.
[0025] Please see Figures 1-7As one embodiment of the mounting bracket 18: a limiting telescopic rod 26 is provided between the mounting bracket 18 and the mounting top plate 7. The limiting telescopic rod 26 is located on both sides of the first electric push rod 16 and extends and retracts synchronously with the first electric push rod 16. The setting of the limiting telescopic rod 26 can share the load of the first electric push rod 16, improve the stability of the first electric push rod 16 when controlling the movement of the mounting bracket 18, and improve the stability of the pressure roller 6 when pressing the rolled aluminum plate.
[0026] In summary, the working principle and specific workflow of this utility model are as follows: When using this utility model, the free end of the aluminum plate to be wound can be inserted into the slot 5. In this way, when the tensioning roller 2 rotates, the connecting end of the aluminum plate and the inner wall of the slot 5 press against each other, realizing the initial positioning of the aluminum plate when it is wound on the tensioning roller 2. In this way, when the tensioning roller 2 rotates, the aluminum plate can be well wrapped around the surface of the tensioning roller 2 to achieve winding. Then, the first electric push rod 16 is extended, and the mounting frame 18 is controlled by the first electric push rod 16 to drive the pressure roller 6 to descend, so as to achieve the top of the aluminum plate being pressed when it is rolled up. The pressing force can be flexibly adjusted according to the data fed back by the pressure detector 17. At the same time, the aluminum sheet is wound up by controlling the rotation of the tensioning shaft 2 through the winding motor 3. After the initial winding, the expansion of the tensioning roller 2 can be controlled to make the connection between the tensioning roller 2 and the aluminum coil tighter; Here, existing tension rollers, guide rollers, guide frames, cutting equipment, etc. used in the aluminum plate conveying process can be installed at the feeding end of the fixed frame 1 for conveying the aluminum plate and cutting it after winding. This part can be achieved by existing products and structures, and this utility model will not elaborate on it. During the winding process described above, the edge position of the aluminum plate being conveyed can be monitored by the edge detection camera 8, and the data can be fed back to the PLC control system. When the edge of the aluminum plate deviates, the second electric push rod 24 can control the mounting shaft 25 to move the corresponding inner limit plate 22 or outer limit plate 23 in time to correct the deviation during the aluminum plate conveying process and improve the edge accuracy and stability when the aluminum plate is rolled up. Here, the inner limiting plate 22 and the outer limiting plate 23 are installed by the cooperation of the mounting shaft 25 and the bearing, so that the aluminum plate being conveyed can form rolling friction with the inner limiting plate 22 or the outer limiting plate 23 instead of sliding friction. This can reduce the sliding wear at the edge of the aluminum plate. After winding is completed, it can be cut using the existing cutting structure and then unloaded. During unloading, the expanded tensioning shaft 2 retracts back to its original position, which relieves the pressure of the tensioning shaft 2 on the inner wall of the aluminum coil, so as to better achieve the unloading of the aluminum coil. During unloading, the first electric push rod 16 controls the mounting frame 18 to move the pressure roller 6 to its original position, and starts the second lead screw motor 15. The second lead screw motor 15 controls the operation of the second ball screw 13, so that the second lead screw nut 14 can drive the push frame 10 to move horizontally. The push frame 10 can control the movement of the push plate 9, and the push plate 9 pushes the aluminum coil off the tensioning shaft 2, realizing the unloading of the coiled aluminum coil and improving the convenience of unloading. In this utility model, both the first ball screw 19 and the second ball screw 13 can be surface protected by existing corrugated cover products. In this utility model, the operation of related electrical components such as motors and electric push rods can be controlled by a PLC control system according to a set program. The specific working process and working principle of this utility model have been described in detail. Based on the above working process and working principle, those skilled in the art should know the specific circuit connection relationship and implement it through existing technology. Furthermore, the circuit connection relationship between related electrical components and the specific driver program are not the subject of protection of this utility model, and this utility model will not elaborate on them.
