Description

Technical Field

[0001] This application relates to the field of aluminum sheet uncoiling technology, and in particular to an aluminum sheet loading device. Background Technology

[0002] Before use, aluminum sheets are generally processed into coils by a winding machine to form aluminum coils, thereby facilitating transportation and storage. When using aluminum sheets, aluminum sheet loading equipment is needed for unwinding, leveling and other operations.

[0003] A common aluminum sheet loading device in related technologies includes a frame with an unwinding roller rotatably mounted on the side wall of the frame. The aluminum coil is wrapped around the unwinding roller for unwinding. To ensure the stability of the aluminum coil during unwinding, a set of side baffles is usually installed on the unwinding roller. The side baffles limit and constrain the two sides of the aluminum coil to prevent the aluminum sheet on the aluminum coil from shifting along the axial direction of the aluminum coil during rotation. This is especially effective for narrower aluminum coils, as it can prevent the aluminum sheet from accidentally unwinding from the aluminum coil.

[0004] In the process of developing this application, it was found that the technology has at least the following problems: the diameter of the side baffle is fixed and the constraint range of the aluminum coil cannot be changed, while the diameter of the aluminum plate wound on the aluminum coil is different. If the diameter of the side baffle is too small, the aluminum plate on the aluminum coil may be at risk of unwinding; if the diameter of the side baffle is too large, the aluminum plate will move between the two side baffles for a long time when it is unwinding from the aluminum coil, and during this time, there is relative movement between the aluminum plate and the side baffle, which leads to a longer relative friction time between the side baffle and the aluminum plate, which may cause wear on the side wall of the aluminum plate. Utility Model Content

[0005] To facilitate the limiting of aluminum coils of different diameters, and to minimize the contact between the aluminum plate and the side baffle while ensuring that there is no risk of the aluminum plate decoiling, thereby reducing wear on the side wall of the aluminum plate, this application provides an aluminum plate loading device.

[0006] The aluminum sheet loading equipment provided in this application adopts the following technical solution:

[0007] An aluminum sheet loading device includes a frame, on which an unwinding roller is rotatably mounted. A set of side baffles are symmetrically arranged on the unwinding roller. Several grooves are evenly and spaced along the circumferential direction on the side baffles. The grooves are opened along the radial direction of the side baffles and penetrate the outer peripheral wall of the side baffles. An extension guard plate is slidably mounted in the groove. The end of the extension guard plate away from the unwinding roller can extend out of the groove. An adjustment component is also provided on the side baffles. The adjustment component is used to drive all the extension guard plates to slide and can fix the extension guard plates.

[0008] By adopting the above technical solution, when it is necessary to limit aluminum coils of different diameters, the length of the extension guard plate extending out of the slide groove can be adjusted by adjusting the component, thereby changing the constraint range of the side baffle on the aluminum coil. For aluminum coils with larger diameters, the extension guard plate can be extended appropriately to increase the lateral support of the aluminum coil and prevent the aluminum plate from unwinding. For aluminum coils with smaller diameters, the extension guard plate can be retracted appropriately to minimize the contact between the aluminum plate and the side baffle while ensuring that there is no risk of the aluminum plate unwinding.

[0009] Preferably, the adjusting assembly includes a fixed sleeve, a movable ring, a connecting rod, and a fixing member. The fixed sleeve is fixedly installed on one side of the two side baffles that are opposite to each other. The fixed sleeve coincides with the axis of the unwinding roller. The movable ring is sleeved on the fixed sleeve and can slide along the axis of the fixed sleeve. Several connecting rods are provided, each corresponding to an extension guard plate. One end of the connecting rod is hinged to the corresponding extension guard plate, and the other end of the connecting rod is hinged to the movable ring. The fixing member is used to fix the position of the connecting rod.

[0010] By adopting the above technical solution, when the extension guard plate needs to extend out of the chute, the movable ring is driven to slide and move closer to the side baffle, the distance between the movable ring and the side baffle decreases, the axial component of the connecting rod in the unwinding roller decreases, and the radial component in the unwinding roller increases, thereby driving the extension guard plate out of the chute; when the extension guard plate needs to retract into the chute, the movable ring is driven to slide and move away from the side baffle, the distance between the movable ring and the side baffle increases, the axial component of the connecting rod in the unwinding roller increases, and the radial component in the unwinding roller decreases, thereby driving the extension guard plate retract into the chute.

[0011] Preferably, the fixing element is an adjusting nut, and the peripheral wall of the fixing sleeve is threaded along the axial direction of the fixing sleeve. The adjusting nut is threadedly engaged with the fixing sleeve, and the adjusting nut is rotatably connected to the movable ring.

[0012] By adopting the above technical solution, when it is necessary to drive the extension guard plate to retract or extend from the slide groove, the adjusting nut is rotated. Since the adjusting nut is threadedly engaged with the fixed sleeve, the adjusting nut will move along the axial direction of the fixed sleeve. The adjusting nut is also rotatably connected to the movable ring. The axial sliding of the adjusting nut along the fixed sleeve will drive the movable ring to slide along the axial direction of the fixed sleeve. When the adjusting nut is adjusted to the appropriate position, the threaded engagement between the adjusting nut and the fixed sleeve fixes the position of the movable ring, thereby fixing the position of the extension guard plate and ensuring the stability of the extension guard plate position.

[0013] Preferably, the adjusting nut has a groove on its end face facing the movable ring in the circumferential direction, and the movable ring has a fixed block on its end face facing the adjusting nut. The block is embedded in the groove and can move along the opening direction of the groove.

[0014] By adopting the above technical solution, the cooperation between the insert and the groove realizes the rotational connection between the adjusting nut and the movable ring; when the adjusting nut is rotated, the insert slides in the groove, so that the rotation of the adjusting nut will not drive the movable ring to rotate, while the movement of the adjusting nut along the axial direction of the fixed sleeve can drive the movable ring to slide along the axial direction of the fixed sleeve, thereby realizing the adjustment of the position of the extension guard plate.

[0015] Preferably, a rubber pad is fixedly provided on the peripheral wall of the adjusting nut.

[0016] By adopting the above technical solution, the rubber pad increases the friction of the adjusting nut's peripheral wall. When the adjusting nut is turned, the operator's hand comes into contact with the rubber pad, making it less likely to slip, which makes the adjustment process more convenient and labor-saving, and improves the ease and comfort of operation.

[0017] Preferably, a guide groove is formed on the outer peripheral wall of the fixed sleeve along the axial direction of the fixed sleeve, and a guide block is fixedly provided on the inner wall of the movable ring, the guide block sliding in the guide groove.

[0018] By adopting the above technical solution, the guide block and guide groove provide guidance for the axial sliding of the movable ring along the fixed sleeve, ensuring that the movable ring can move stably and accurately along the axial direction of the fixed sleeve, minimizing the possibility of the movable ring shifting or shaking during movement, thereby ensuring that the sliding direction of the extension guard plate and the sliding direction of the corresponding connecting rod are always in the same plane.

[0019] Preferably, the sidewall of the extended guard plate away from the fixed sleeve is flush with the surface of the sidewall of the side baffle away from the fixed sleeve.

[0020] By adopting the above technical solution, it is ensured that the sides of the aluminum coil can receive continuous and flat support and restraint during the unwinding process; it minimizes the uneven force on the sides of the aluminum coil caused by the unevenness of the extension guard plate and the side baffle surface, and at the same time makes the aluminum plate unwinding process smoother, reduces friction and wear between the aluminum plate and the side baffle, and further improves the unwinding quality of the aluminum plate.

[0021] Preferably, the side baffle and the unwinding roller are detachably connected by connecting bolts.

[0022] By adopting the above technical solution, when it is necessary to replace the aluminum coil, the side baffle can be removed from the unwinding roller by disassembling the connecting bolts, and then reinstalled after the aluminum coil replacement operation is completed.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting side baffles, slides, extension guards, and adjustment components, the dynamic adjustment of the constraint range of the aluminum coil by the side baffles is realized. The extension guards can slide radially along the slides. The extension length of all extension guards is controlled synchronously by the adjustment components. This can provide sufficient lateral support for large-diameter aluminum coils to prevent unwinding, and reduce the contact area with the aluminum plate when unwinding small-diameter aluminum coils, thereby reducing friction and wear.

[0025] 2. By setting a fixed sleeve, a movable ring, a connecting rod, an adjusting nut, a groove, and an insert, the adjusting nut engages with the fixed sleeve through a thread, driving the movable ring to move axially. The connecting rod extends the guard plate synchronously through linkage. The connection between the groove and the insert ensures that the adjusting nut only transmits axial displacement without causing the movable ring to rotate. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses an aluminum sheet loading device. (Refer to...) Figure 1The system includes a frame 1, on which an unwinding roller 11 is rotatably mounted. A set of side baffles 2 are symmetrically arranged on the unwinding roller 11, and several grooves 21 are evenly and spaced along the circumference of the side baffles 2. The grooves 21 are opened along the radial direction of the side baffles 2 and penetrate the outer circumferential wall of the side baffles 2. Extended guard plates 22 are slidably mounted within the grooves 21, with one end of the extended guard plate 22 extending out of the groove 21 away from the unwinding roller 11. Specifically, six grooves 21 are opened on the side baffles 2, penetrating both ends of the side baffles 2. Six extended guard plates 22 are also correspondingly set, and the cross-section of the extended guard plates 22 is I-shaped, matching the cross-sectional shape of the grooves 21 in the opening direction to ensure the guiding effect of the extended guard plates 22 when sliding within the grooves 21.

[0032] Reference Figure 1 For aluminum coils 5 with larger diameters, the extension guard plate 22 can be extended appropriately beyond the slide groove 21 to increase lateral support for the aluminum coil 5 and prevent the aluminum plate 51 from unwinding. For aluminum coils 5 with smaller diameters, the extension guard plate 22 can be retracted appropriately into the slide groove 21 to minimize contact between the aluminum plate 51 and the side baffle 2, while ensuring that there is no risk of the aluminum plate 51 unwinding.

[0033] Reference Figure 1 In order to facilitate the simultaneous sliding of all the extended guard plates 22 and to fix the position of the extended guard plates 22, as shown in the figure, the side baffle 2 is also provided with an adjustment component 3. The adjustment component 3 is used to drive all the extended guard plates 22 to slide and to fix the extended guard plates 22.

[0034] Reference Figure 1 and Figure 2 Specifically, the adjusting component 3 includes a fixed sleeve 31, a movable ring 32, a connecting rod 33, and a fixing element. The fixed sleeve 31 is fixedly installed on the side of the two side baffles 2 that are opposite to each other. The fixed sleeve 31 coincides with the axis of the unwinding roller 11 and is sleeved on the unwinding roller 11. The movable ring 32 is sleeved on the fixed sleeve 31 and can slide along the axis of the fixed sleeve 31. There are several connecting rods 33. In this embodiment, there are six connecting rods 33, and they correspond one-to-one with the extension guard plate 22. One end of the connecting rod 33 is hinged to the corresponding extension guard plate 22, and the other end of the connecting rod 33 is hinged to the movable ring 32.

[0035] Reference Figure 1 and Figure 2 The fixing component, specifically the adjusting nut 34, is used to secure the position of the connecting rod 33. A thread is formed on the peripheral wall of the fixing sleeve 31 along its axial direction. The adjusting nut 34 engages with the threaded fixing sleeve 31, and is rotatably connected to the movable ring 32. A rubber pad 341 is fixedly provided on the peripheral wall of the adjusting nut 34 to increase friction when rotating it and prevent slippage.

[0036] To ensure the stability of the rotatable connection between the adjusting nut 34 and the movable ring 32, refer to... Figure 3 The adjusting nut 34 has a groove 342 circumferentially formed on its end face facing the movable ring 32. A block 321 is fixedly mounted on the end face of the movable ring 32 facing the adjusting nut 34. The block 321 is embedded in the groove 342 and can move along the direction of the groove 342. Specifically, the groove 342 is a dovetail groove circumferentially formed on the adjusting nut 34, and the block 321 is a dovetail block circumferentially formed on the movable ring 32. When the adjusting nut 34 is rotated, the block 321 moves within the groove 342, preventing the rotation of the adjusting nut 34 from causing the movable ring 32 to rotate. However, the axial movement of the adjusting nut 34 along the fixed sleeve 31 causes the movable ring 32 to slide axially along the fixed sleeve 31, thereby adjusting the position of the extension guard plate 22 and ensuring the stability of the rotatable connection between the adjusting nut 34 and the movable ring 32.

[0037] To further ensure the guiding nature of the movable ring 32 sliding along the axial direction of the fixed sleeve 31, refer to Figure 3 A guide groove 311 is formed on the outer peripheral wall of the fixed sleeve 31 along the axial direction of the fixed sleeve 31. A guide block 322 is fixedly provided on the inner wall of the movable ring 32, and the guide block 322 slides within the guide groove 311. The guide block 322 and the guide groove 311 provide guidance for the sliding of the movable ring 32, minimizing the risk of twisting or shaking of the movable ring 32 during movement, thereby improving the stability of the extension guard plate 22 and the connecting rod 33.

[0038] Reference Figure 3 When it is necessary to drive the extension guard plate 22 to slide to change the degree of extension of the extension guard plate 22 in the slide groove 21, the adjusting nut 34 is turned forward or backward, so that the extension guard plate 22 drives the movable ring 32 to move closer to or away from the side baffle 2. The included angle between the connecting rod 33 and the extension guard plate 22 decreases or increases accordingly, thereby pushing the extension guard plate further out or pulling it back into the slide groove 21.

[0039] For easier replacement of aluminum coil 5, refer to... Figure 2 The side baffle 2 and the unwinding roller 11 are detachably connected by connecting bolts 4. Specifically, connecting holes are provided on the peripheral walls of the fixing sleeve 31 and the unwinding roller 11. The connecting bolts 4 are inserted into the connecting holes on the fixing sleeve 31 and the unwinding roller 11, and are threadedly engaged with the connecting holes on the unwinding roller 11. When it is necessary to replace the aluminum coil 5, the side baffle 2 on the side away from the frame 1 on the unwinding roller 11 can be removed by disassembling the connecting bolts 4. After the aluminum coil 5 is replaced, it can be reinstalled.

[0040] Reference Figure 1 and Figure 2The side wall of the extended guard plate 22 away from the fixed sleeve 31 is flush with the side wall of the side baffle 2 away from the fixed sleeve 31. This ensures that during the unwinding process, the aluminum coil 5 and the side of the aluminum plate 51 detached from the aluminum coil 5 can receive continuous, flat support and restraint.

[0041] The implementation principle of an aluminum plate feeding device according to an embodiment of this application is as follows: When it is necessary to unwind and feed the aluminum coil 5, the side baffle 2 on the side away from the frame 1 on the unwinding roller 11 is first removed. After the aluminum coil 5 is installed on the unwinding roller 11, the side baffle 2 is then installed on the unwinding roller 11 using the connecting bolts 4. Next, the operator rotates the adjusting nut 34, which rotates and moves closer to the side baffle 2, thereby driving the movable ring 32 closer to the side baffle 2. The included angle between the connecting rod 33 and the extension guard plate 22 decreases accordingly, thereby pushing the extension guard plate 22 to extend outward along the slide groove 21. As the extension guard plate 22 extends, the restraint range of the side baffle 2 on the aluminum coil 5 expands, providing sufficient lateral support for the aluminum coil 5 and effectively preventing the aluminum plate 51 from unwinding during the unwinding process. Moreover, while ensuring that there is no risk of the aluminum plate 51 unwinding, the contact between the extension guard plate 22 and the aluminum plate 51 is minimized, reducing the possibility of wear on the side wall of the aluminum plate 51 due to friction.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
