Description

Technical Field

[0001] This invention belongs to the field of aluminum alloy coiling technology, specifically an aluminum alloy sheet coiling device and its coiling method. Background Technology

[0002] Aluminum alloy sheet winding equipment is a key piece of equipment used to wind aluminum alloy sheets into rolls for storage, transportation, and subsequent processing. With the widespread application of aluminum alloys in aerospace, automotive, and transportation industries, the demand for sheet winding equipment is increasing daily. In the production process, traditional winding equipment suffers from several technical problems, such as unstable winding quality, difficulty in unwinding, and poor adaptability to sheets of different widths. These problems mainly stem from inconsistent support sleeve dimensions, the lack of effective limiting devices, and limitations in the equipment design.

[0003] Chinese patent application number CN202122759007.X discloses an aluminum alloy extruded sheet winding device, including a drum. A drive frame, a pusher, and a receiving component are respectively provided on the outer side of the drum. A block is provided inside the drum via a transmission component. Baffles are rotatably connected to one edge of the upper and lower ends of the block, and sliding grooves are provided at both ends of the block. Two baffles are slidably disposed on the inner wall of the drum, and connecting rods are rotatably connected to the side walls of both baffles. Slider blocks are rotatably connected to the ends of both connecting rods, and each slider slides in cooperation with one of the two sliding grooves. The beneficial effect of this solution is that it facilitates the neat winding of aluminum strips of different widths when winding aluminum strips. After winding, it makes it convenient for workers to unload heavier aluminum strip rolls, saving time and effort. However, this solution does not address how to solve or protect the aluminum alloy sheet from cracking during use.

[0004] During the cutting and conveying of aluminum alloy sheets, the binding force on the ends of the sheets on the winding assembly is sometimes lost during the cutting process, causing them to expand rapidly under stress, affecting the safety of the user. At the same time, due to the constraints of different usage conditions, the width of the sheets needs to be corrected and cut again in the later stage, which affects the efficiency of the use of aluminum alloy sheets.

[0005] Therefore, in order to solve the above-mentioned technical problems, the present invention proposes an aluminum alloy sheet winding device and a winding method thereof. Summary of the Invention

[0006] The purpose of this invention is to address the above-mentioned problems. This invention provides an aluminum alloy sheet winding device and its winding method, which has the advantages of quickly processing the wound sheet and ensuring that the coil does not loosen during the processing.

A plurality of card plates are connected to the fixing plate, and a card slot for connecting the winding component is also provided on the fixing plate. The card slot is located between the plurality of card plates.

[0013] Preferably, the winding assembly includes a connecting roller, the two ends of which are distributed along the length direction and can engage with the slot, a plurality of rotating rods are rotatably provided on the connecting roller, a plurality of arc-shaped plates are connected to the end of the rotating rod away from the connecting roller, and there is a gap between two adjacent arc-shaped plates.

[0014] Preferably, the transmission component includes a mounting rod and a connecting rod, both of which are connected to the connecting shell.

[0015] Preferably, the working component includes a slide rail, on which a plurality of sliders are slidably disposed, and a cutting part is connected to each slider.

[0016] A winding method using an aluminum alloy sheet winding device includes the following steps:

[0017] S1. Use the moving component to move the winding component so that the winding component is connected to the fixed component;

[0018] S2. When the winding assembly approaches the fixed assembly, it drives the fixed disk to rotate, so that the slot corresponds to the connecting roller in the winding assembly, ensuring that the connecting roller engages with the slot.

[0019] S3. The drive plate abuts against the inner ring of the arc plate to lock the winding assembly, while controlling the cutting assembly to move closer to the outer periphery of the winding assembly.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] like Figures 1-9As shown, this embodiment discloses an aluminum alloy sheet winding device, including two connecting shells 1 for connecting and fixing components. One end of each connecting shell 1 is connected to a fixing component 4 for constraining and connecting a winding component 3. A winding component 3, made of aluminum alloy sheet, is connected between the fixing components 4. The winding component 3 is detachably connected to the fixing components 4. One end of each connecting shell 1 is connected to a moving component 2, which allows the winding component 3 outside the winding device to be moved onto the fixing components 4 for constraint. A transmission component for processing and conveying the aluminum alloy sheet on the winding component 3 is located on the side of the winding component 3 away from the moving component 2. 5. The two ends of the transmission component 5 distributed along the length direction are connected to the connecting shell 1. The upper part of the fixing component 4 is provided with a cutting component 7 for cutting aluminum alloy sheet. The cutting component 7 is located on the outer periphery of the winding component 3. In use, the winding component 3 is moved to the target area, and then the moving component 2 is used to move the winding component 3, so that the winding component 3 is engaged with the fixing component 4. At the same time, it is ensured that the aluminum alloy sheet on the winding component 3 can be transferred to the aluminum alloy sheet processing device through the transmission component 5 to realize the processing of the aluminum alloy sheet. The cutting component 7 is used to cut the surface of the aluminum alloy sheet to ensure that the aluminum alloy sheet on the winding device can be processed normally.

[0039] To improve the safety of the aluminum alloy sheet on the winding assembly 3 during the winding process, the cutting assembly 7 includes two support plates 701 for load-bearing and restraint. Connecting blocks 702 are connected to both ends of the two support plates 701 along their length. The connecting blocks 702 are connected to the connecting plates, which support and control the height and angle of the cutting assembly 7. The connecting plates are also connected to the fixing assembly 4 to ensure the stability of the support plates 701. A protective strip 7021 is connected inside the connecting block 702. A cavity is formed within the connecting block 702, and the protective strip 7021 is housed within this cavity. One end of the protective strip 7021 is connected to one of the support plates 701. The end of the connecting block 702 furthest from the protective strip 7021 is fixedly connected to another mounting plate 701. When the aluminum alloy sheet on the winding assembly 3 is in normal use, the protective strip 7021 is hidden in the connecting block 702, and the mounting plates 701 are located at both ends of the connecting block 702. When the aluminum alloy sheet on the winding assembly 3 becomes loose during the cutting process, it may break open under the action of elasticity. At this time, the protective strip 7021 is controlled to drive the length of the mounting plate 701 to extend, causing the mounting plate 701 to move and make the mounting plate 701 come into contact with the winding assembly 3, thereby covering the outer circumference of the winding assembly 3 and preventing the aluminum alloy sheet on the winding assembly 3 from popping open and affecting the safety of the user.

[0040] It should be noted that, in order to ensure that the protective tape 7021 can move the mounting rod 701 and press and protect the sheet metal on the winding assembly 3, the material of the protective tape 7021 is set to a flexible metal material to protect the winding assembly 3.

[0041] Furthermore, to facilitate the cutting of aluminum alloy sheets and improve processing efficiency, the cutting assembly 7 also includes a slide 703. The two ends of the slide 703, distributed along its length, are connected to two connecting blocks 702 respectively. The effective cutting length of the slide 703 is greater than the winding length of the winding assembly 3, ensuring that the cutting assembly 7 can cut the coil on the winding assembly 3. A sliding seat 7031 is connected to the slide 703. The sliding seat 7031 can be driven to move along the slide 703 by electric, magnetic, or telescopic rod means. A cutting blade 7 for cutting the aluminum alloy sheet is movably mounted on the sliding seat 7031. 032, the sliding seat 7031 slides on the slide groove 703, driving the cutting blade 7032 to move and achieve the cutting of aluminum alloy sheet. At the same time, in order to prevent the cutting blade 7032 from contacting the sheet on the winding assembly 3 when stationary, the cutting blade 7032 is rotatably connected to the sliding seat 7031. When there is no need to cut the winding assembly 3, the cutting blade 7032 is adjusted to rotate on the sliding seat 7031 to a position where it does not contact the winding assembly 3. At the same time, as the thickness of the winding assembly 3 decreases, the rotation of the cutting blade 7032 on the sliding seat 7031 can also be controlled to change the cutting depth of the cutting blade 7032, thereby ensuring that the cutting blade 7032 can meet the cutting position on the winding assembly 3.

[0042] Furthermore, to achieve the relocation of the winding assembly 3 and reduce the time cost of manually changing the roll material, the moving assembly 2 includes two moving rods 201. A crossbar connects the two moving rods 201 to maintain the two moving rods 201 at the same rotation angle. The two moving rods 201 are respectively close to the two connecting shells 1. A lifting rod 202 is provided on the side of the moving rod 201 closest to the winding assembly 3. A crossbar is also connected between the lifting rods 202 to maintain a constant lifting angle of the lifting rods 202. The crossbars are all located at the rotational connection between the moving rods 201 and the lifting rods 202, and will not interfere with their rotation angle. A pneumatic telescopic rod 203 is connected to the end of the lifting rod 202 away from the moving rod 201. The angle of the lifting rod 202 changes by the extension and retraction length of the pneumatic telescopic rod 203. When the length of the pneumatic telescopic rod 203 extends, the end of the lifting rod 202 moves away from the fixed component 4. When the length of the pneumatic telescopic rod 203 shortens, the end of the lifting rod 202 moves closer to the fixed component 4. It should also be noted that both the moving rod 201 and the end of the lifting rod 202 away from the crossbar have grooves for engaging and moving the winding component 3. In use, the winding component 3 is placed near the moving rod 201. By rotating the moving rod 201, the groove on the moving rod 201 engages with the winding component 3. Then, the moving rod 201 is rotated, which simultaneously causes the lifting rod 202 to rotate towards the end near the moving rod 201. The moving rod 201 is used to rotate the winding component 3 onto the lifting rod 202, and the rotation of the lifting rod 202 engages the winding component 3 with the fixed component 4.

[0043] Furthermore, a rotating part 2011 is connected inside the connecting shell 1. The rotating part 2011 is connected to the moving rod 201. The structure of the rotating part 2011 includes, but is not limited to, a rotating motor, a linkage structure, or other components that can rotate the moving rod 201, so as to ensure that the rotation angle of the moving rod 201 can be controlled by the rotating part 2011.

[0044] Furthermore, to better constrain the position of the winding assembly 3 and ensure its proper use on the winding device, the fixing assembly 4 includes two bases 401 for connection and constraint. The two bases 401 are rotatably connected to the connecting shell 1, and a fixing plate 402 is rotatably connected to one end of each base 401 facing each other. This allows the fixing plate 402 to rotate relative to the bases 401. Multiple clamping plates 403 are connected to the fixing plate 402, and the movement of the clamping plates 403 on the fixing plate 402 allows for the adjustment of the inner ring of the winding assembly 3. To facilitate the movement of the clamping plate 403, a threaded rod is provided on the fixed disk 402 to control the position movement of the clamping plate 403. The fixed disk 402 also has a clamping groove 4021 for connecting the winding assembly 3. The clamping groove 4021 is located among multiple clamping plates 403. When the bearing of the winding assembly 3 is connected to the fixed assembly 4, the two ends of the bearing of the winding assembly 3 distributed along the length direction can respectively engage with the clamping groove 4021. Then, the clamping plate 403 moves on the fixed disk 402 to achieve the clamping of the winding assembly 3 and ensure the stable constraint of the winding assembly 3.

[0045] To ensure that the base 401 can drive the winding assembly 3 to rotate, a drive unit 8 is connected to the connecting shell 1. The drive unit 8 includes a servo motor, a transmission belt, and a bearing. The bearing is connected to the base 401, so that when the base 401 needs to rotate, the drive unit 8 drives the base 401 to rotate.

[0046] Furthermore, the winding assembly 3 includes a connecting roller 301, which is located in the middle region of the winding assembly 3. Both ends of the connecting roller 301, distributed along its length, can engage with the slots 4021. Multiple rotating rods 3021 are rotatably mounted on the connecting roller 301. Multiple arc-shaped plates 302 are connected to the ends of the rotating rods 3021 away from the connecting roller 301. The multiple arc-shaped plates 302 cooperate to cover the connecting roller 301, and there is a gap between adjacent arc-shaped plates 302 to facilitate the application of aluminum alloy. When the sheet metal is connected to the winding assembly 3, the ends of the aluminum alloy sheet metal can be clamped and constrained in the gap between the two arc plates 302, which facilitates the winding and fixing of the aluminum alloy sheet metal on the surface of the arc plate 302. In order to enable the winding assembly 3 to wind or unwind aluminum alloy sheet metal of different diameters, the rotating rod 3021 can be rotated to change the distance between the outer circumference of the connecting roller 301 and the inner ring of the arc plate 302, thereby changing the diameter of the arc plate 302 and ensuring that the winding assembly 3 can meet the usage requirements.

[0047] Furthermore, during the processing of the aluminum alloy sheet on the winding assembly 3, the transmission assembly 5 includes a mounting rod 501 and a connecting rod 502. Both the mounting rod 501 and the connecting rod 502 are connected to the connecting shell 1. The aluminum alloy sheet is sequentially connected to the mounting rod 501 and the connecting rod 502 through mutual cooperation. The transmission and movement of the aluminum alloy sheet are realized by the mutual cooperation between the mounting rod 501 and the connecting rod 502. At the same time, a working assembly 6 is provided between the mounting rod 501 and the connecting rod 502. The working assembly 6 does not contact the mounting rod 501 and the connecting rod 502. The working assembly 6 cuts and processes the sheet that has passed through the transmission assembly 5 to ensure that the aluminum alloy sheet that has passed through the working assembly 6 can meet the winding requirements.

[0048] Furthermore, the working component 6 includes a slide rail 602, on which a plurality of sliders 601 are slidably mounted. A cutting section 603 is connected to each slider 601. The position of the sliders 601 is adjusted by the slide rail 602, thereby adjusting the spacing of the cutting section 603 to ensure that the cutting by the cutting section 603 can meet the processing requirements of the board.

[0049] In use, the winding assembly 3 is placed on the side close to the moving assembly 2, thereby controlling the moving assembly 2 to move the position of the winding assembly 3. At the same time, the winding assembly 3 is moved towards the side close to the fixed assembly 4, and the fixed assembly 4 constrains the position of the winding assembly 3. Then, the cutting assembly 7 comes into contact with the surface of the winding assembly 3, and the sheet material on the winding assembly 3 is pulled out and comes into contact with the transmission assembly 5. The rotation of the transmission assembly 5 drives the sheet material on the winding assembly 3 to move, so that it is processed by the cutting of the working assembly 6.

[0050] When the winding assembly 3 approaches the moving rod 201, the rotating part 2011 drives the moving rod 201 to flip, causing the end of the moving rod 201 to contact both ends of the connecting roller 301. Then, the rotating part 2011 and the pneumatic telescopic rod 203 are controlled to rotate simultaneously, causing the end of the moving rod 201 to move closer to the lifting rod 202. At the same time, the end of the lifting rod 202 rotates closer to the moving rod 201. Thus, the moving rod 201 moves the winding assembly 3 onto the lifting rod 202. Then, the pneumatic telescopic rod 203 drives the lifting rod 202 to rotate away from the moving rod 201, bringing the winding assembly 3 closer to the fixed assembly 4.

[0051] During the rotation of the lifting rod 202, the fixed component 4 is controlled to rotate, which causes the fixed disk 402 to rotate, making the opening of the slot 4021 tilted and corresponding to the position of the lifting rod 202. As the rotation angle of the lifting rod 202 increases, the winding component 3 can slide off the lifting rod 202. At the same time, the connecting roller 301 contacts the slot 4021 and is engaged by the slot 4021. Simultaneously, the fixed disk 402 is controlled to rotate, thereby fixing the position of the winding component 3. Then, the clamping plate 403 is controlled to move, causing the clamping plate 403 to abut against the inner ring of the arc plate 302, ensuring the stability of the position of the winding component 3.

[0052] After the fixing component 4 has fixed the winding component 3, the cutting component 7 is used to protect the outside of the winding component 3 to prevent the measuring tape on the winding component 3 from popping out and affecting the normal use of the device. At the same time, the end of the plate on the winding component 3 is taken out and makes contact with the mounting rod 501 and the connecting rod 502. The rotation of the mounting rod 501 and the connecting rod 502 is used to move the plate on the winding component 3.

[0053] Furthermore, based on actual usage requirements, the spacing of the slider 601 on the slide rail 602 is adjusted, thereby achieving spacing control of the cutting section 603. When the board passes through the mounting rod 501 and the connecting rod 502, the cutting section 603 completes the cutting process of the board, ensuring that the processed board meets usage requirements. If necessary, the cutting blade 7032 on the cutting component 7 can be used to cut the board on the winding component 3, ensuring that the length of the board meets usage requirements.

[0054] When the sheet metal on the winding assembly 3 is in use, due to the stress on the sheet metal, when the sheet metal on the winding assembly 3 loses its restraint, the sheet metal on the arc plate 302 will quickly spring open, affecting the user's safety. Then, when the sheet metal on the winding assembly 3 becomes loose, the control protective belt 7021 drives the length of the mounting plate 701 to extend, causing one of the mounting plates 701 to move, causing the mounting plate 701 to come into contact with the winding assembly 3. With the cooperation of the two mounting plates 701 and the protective belt 7021, an arc shape is formed, thereby covering and locking the outer circumference of the winding assembly 3 to prevent the aluminum alloy sheet metal on the winding assembly 3 from springing open.

[0055] Example 2

[0056] Although Embodiment 1 discloses the processing and cutting of aluminum alloy sheet on the winding assembly 3, it does not describe how to use the winding assembly 3 to wind up loose sheet.

[0057] The connecting roller 301 and the arc plate 302 are connected and fixed to the fixing component 4, and the plate to be wound is pressed against the transmission component 5. The gap between the end and the arc plate 302 is locked to ensure that the aluminum alloy plate can be wound on the arc plate 302 when the fixing component 4 drives the winding component 3 to rotate. At the same time, while the aluminum alloy plate is wound on the arc plate 302, the two mounting plates 701 and the protective belt 7021 are used to press against the aluminum alloy plate on the arc plate 302 to ensure that there are no gaps between the aluminum alloy plates.

[0058] Meanwhile, according to the usage requirements of aluminum alloy sheet, the rotating rod 3021 drives the arc plate 302 to move, thereby changing the distance between the arc plate 302 and the connecting roller 301. In this way, when the aluminum alloy sheet comes into contact with the arc plate 302, the winding diameter of the aluminum alloy sheet can be changed, ensuring the convenience of the winding assembly 3 in transportation and use.

[0059] During the process of transporting aluminum alloy sheet using the transmission component 5, the aluminum alloy sheet can be cut by the cutting part 603 according to the usage requirements of the aluminum alloy sheet, so that the cut aluminum alloy sheet meets the usage requirements. At the same time, when the length of the aluminum alloy sheet on the winding component 3 meets the usage requirements, the aluminum alloy sheet is cut by the cutting blade 7032, completing the winding of the aluminum alloy sheet by the winding component 3 and fixing the end.

[0060] After the end of the aluminum alloy sheet is fixed, the control plate 403 moves to the side closer to the slot 4021, while the fixing plate 402 is flipped so that the notch of the slot 4021 is close to the moving component 2, and then the moving component 2 is used to move the wound component 3 out of the fixing component 4 for storage.

[0061] Example 3

[0062] A winding method using an aluminum alloy sheet winding device includes the following steps:

[0063] S1. Move the winding component 3 using the moving component 2 so that the winding component 3 is connected to the fixed component 4.

[0064] S2. When the winding assembly 3 approaches the fixing assembly 4, it drives the fixing disk 402 to rotate, so that the slot 4021 corresponds to the connecting roller 301 in the winding assembly 3, ensuring that the connecting roller 301 is engaged with the slot 4021.

[0065] S3, the drive plate 403 abuts against the inner ring of the arc plate 302 to lock the winding assembly 3, while controlling the cutting assembly 7 to move closer to the outer periphery of the winding assembly 3;

[0066] S4. Connect the sheet material on the winding assembly 3 to the conveying assembly 5 to ensure that the sheet material can be processed by the conveying assembly 5.

[0067] S5. During the movement of the sheet material in the winding assembly 3, the mounting plate 701 and the protective belt 7021 are used to protect the outer periphery of the winding assembly 3, while the cutting blade 7032 and the cutting part 603 are used to cut the sheet material on the winding assembly 3.
