Technical Field
[0001] This utility model relates to the field of winding technology, specifically to a winding machine winding drum. Background Technology
[0002] Winding machines are key pieces of equipment in industries such as metallurgy. Their main function is to continuously wind shaped sheets, strips, and other materials into coils for storage, transportation, and subsequent processing. The coil, as the core component of the winding machine, directly affects the quality and efficiency of the winding process.
[0003] In existing technology, the vast majority of winding machines use drums with a fixed length. These fixed-length drums typically consist of a rigid shaft and baffles (or flanges) fixed at both ends, and their winding width is not adjustable. Therefore, a single winding machine can usually only wind up material of a single width.
[0004] However, in actual industrial production, downstream users often need to produce products of various widths. To accommodate the winding of sheets of different widths, the current method involves equipping each width with a corresponding length of roll. When changing roll specifications, the machine must be stopped, and lifting equipment must be used to remove the old roll from the winding machine before installing the new one. This method not only requires stocking rolls of various specifications, increasing equipment and storage costs, but the changeover process is also cumbersome and time-consuming, severely impacting production line continuity and operational efficiency, and increasing the labor intensity of workers.
[0005] Existing technology has poor roll structure flexibility, low production changeover efficiency, and insufficient adaptability. There is a need for a roll that can quickly, reliably, and accurately adjust its working length to adapt to rolls of different widths. Utility Model Content

[0019] like Figure 1-3As shown, a winding machine drum includes a main shaft 1, a fixed drum 2, a pair of movable drums 4, and a pair of adjusting sleeves 10. The fixed drum 2 is fixedly disposed at the center of the main shaft 1 and is fixedly connected to the main shaft 1. Multiple second support plates 3 are arranged in a ring matrix on both sides of the fixed drum 2 near its edge. The pair of movable drums 4 are respectively sleeved on both sides of the main shaft 1 and are axially movably connected to the main shaft 1. Multiple first support plates 5 are arranged in a ring matrix on the sidewalls of the movable drums 4 corresponding to the sidewalls of the fixed drum 2 near its edge. The multiple first support plates 5 and multiple second support plates 3 are staggered and axially slidably connected to each other via sliding members. The diameter of the virtual cylinder formed by the fixed drum 2 and the second support plates 3 is equal to the diameter of the virtual cylinder formed by the movable drums 4 and the first support plates 5. The pair of adjusting sleeves 10 are rotatably connected to the sidewalls of the pair of movable drums 4 away from the fixed drum 2 via rotating members 11. The inner sidewall of the adjusting sleeve 10 is provided with... The main shaft 1 has an internal thread 12, and an external thread 13 is provided at the position corresponding to the adjusting sleeve 10. The adjusting sleeve 10 is screwed to the main shaft 1 through the cooperation of the internal thread 12 and the external thread 13. A jaw 14 is axially provided on the side surface of the fixed cylinder 2, the second support plate 3, and the moving cylinder 4. The inner ring of the moving cylinder 4 is provided with a spline 8, and the main shaft 1 is provided with a keyway 9. The spline 8 and the keyway 9 are axially slidably connected. The sliding component includes a slide bar 7 and a slide groove 6. The slide bar 7 is fixedly provided on the side wall of the first support plate 5, and the slide groove 6 is provided on the side wall of the second support plate 3. The slide bar 7 is axially slidably connected to the slide groove 6. A baffle 16 is fixedly provided on the side surface of the moving cylinder 4. The rotating component 11 adopts a plane bearing. An anti-loosening component 15 is provided on the external thread 13 of the main shaft 1 corresponding to the outer side of the adjusting sleeve 10. The anti-loosening component 15 adopts an anti-loosening nut. The fixed cylinder 2 and the second support plate 3, as well as the moving cylinder 4 and the first support plate 5, are integrally formed.
[0020] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows: According to the instruction manual Figure 1-3As can be seen, in this utility model, the two ends of the main shaft 1 are connected to the rotating mechanism of the existing winding machine, which can drive the main shaft 1 to rotate. Before operation, the positions of the pair of movable cylinders 4 are adjusted to meet the required width of the material to be wound. Since the adjusting sleeve 10 is screwed to the external thread 13 on the main shaft 1 through the internal thread 12, rotating the adjusting sleeve 10 can make it move left and right. Since the adjusting sleeve 10 is rotatably connected to the outer wall of the movable cylinder 4 through the rotating part 11, the movable cylinder 4 is staggered with the second support plate 3 on the fixed cylinder 2 through the first support plate 5 and is axially slidably connected through the sliding part. The fixed cylinder 2 is fixedly connected to the center position of the main shaft 1. Therefore, the movable cylinder 4 can only move axially. Rotating the threaded sleeve can drive the movable cylinder 4 and the first support plate 5 to move left and right, that is, move axially, thereby achieving the function of adjusting the width. The diameter of the virtual cylinder formed by the fixed cylinder 2 and the second support plate 3 is equal to the diameter of the virtual cylinder formed by the movable cylinder 4 and the first support plate 5, which can provide good support for the wound material. The material end is inserted into the jaws 14 axially arranged on the side surfaces of the fixed cylinder 2, the second support plate 3, and the moving cylinder 4. Then, the rotating mechanism of the winding machine drives the main shaft 1, the fixed cylinder 2, the second support plate 3, the first support plate 5, and the moving cylinder 4 to rotate circumferentially, thus winding the material. There is an insertion relationship and friction relationship between the material and the moving cylinder 4 through the jaws 14. Under normal circumstances, the moving cylinder 4 will not move axially. During adjustment, the adjusting sleeves 10 on both sides and the moving cylinder 4 are usually adjusted at equal distances. Of course, the existence of errors is allowed, as long as the required width of the material to be wound is met. In this utility model, the winding drum consists of a central fixed cylinder 2 and two moving cylinders 4 on both sides. The moving cylinder 4 can move on the main shaft 1. The first support plate 5 on the side wall of the moving cylinder 4 and the second support plate 3 on the side wall of the fixed cylinder 2 are staggered to ensure support for the material. The overall length of the winding drum can be adjusted without disassembly, which is flexible, improves work efficiency, and reduces the labor intensity of personnel.
[0021] The inner ring of the movable drum 4 is provided with a spline 8, and the main shaft 1 is provided with a keyway 9. The spline 8 and the keyway 9 are axially slidably connected, which further ensures that the movable drum 4 can only move axially, thereby ensuring its stability during winding.
[0022] The sliding component includes a slider 7 and a groove 6. The slider 7 is fixedly installed on the side wall of the first support plate 5, and the groove 6 is opened on the side wall of the second support plate 3. The slider 7 is axially slidably connected to the groove 6. The structure is simple and the sliding is stable.
[0023] Among them, baffles 16 are fixedly installed on the side surface of the movable drum 4 to limit the end face of the wound material and ensure that the wound material is neat.
[0024] Among them, the external thread 13 of the main shaft 1 is provided with an anti-loosening element 15 corresponding to the outer side of the adjusting sleeve 10. The anti-loosening element 15 adopts an anti-loosening nut to further ensure the axial stability of the adjusting sleeve 10 and the moving cylinder 4. The rotating part 11 adopts a plane bearing, which has a simple structure.
[0025] The fixed cylinder 2 and the second support plate 3, as well as the movable cylinder 4 and the first support plate 5, are integrally molded to increase the stability of the overall structure.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
