Description

Technical Field

[0001] This utility model relates to the field of aluminum strip processing, specifically to an integrated machine for slitting and oiling aluminum coils. Background Technology

[0002] Currently, when processing aluminum coils, some coils require rust-preventive oil to be applied after slitting, as per customer demand, before being rolled up. Existing oiling methods have many drawbacks. For example, the common method of applying rust-preventive oil to aluminum strips via a drip applicator, similar to the method used in a steel plate slitting machine (publication number: CN215468397U), suffers from uneven application due to the difficulty in precisely controlling the flow and distribution of the oil. This not only affects the rust-preventive effect of the aluminum coils and reduces product quality but also easily leads to a significant waste of rust-preventive oil, increasing production costs.

[0003] Meanwhile, in actual production, customers have varying requirements for the width of aluminum sheets. To meet this demand, the cutting blade spacing of the slitting machine needs to be adjusted adaptively when producing aluminum sheets of different widths. However, existing technology requires stopping the machine to adjust the cutting blade spacing, and the entire process from stopping to restarting the equipment after the spacing adjustment is completed is time-consuming, severely hindering the continuity of slitting operations and significantly reducing slitting efficiency, thus failing to meet the requirements of large-scale, high-efficiency production. Utility Model Content

[0004] The present invention aims to provide an integrated machine for slitting and coating aluminum coils to solve the problem of uneven coating in existing slitting machines.

[0011] Preferably, as an improvement, the second bridge includes a second material pit, in which a second bridge plate is provided, the feeding end of the second plate being hinged to the frame and capable of communicating with the edge-receiving mechanism.

[0012] Preferably, as an improvement, the tension mechanism includes a tension table that is vertically slidably arranged, a lifting drive component for driving its lifting and lowering is connected to the top of the tension table, a feeding roller is arranged on the front side of the tension table, and a limit ring is detachably arranged on the feeding roller.

[0013] Preferably, as an improvement, the winding mechanism includes a winding shaft, and a pressure arm and a pressure roller are also provided above the winding shaft.

[0014] Preferably, as an improvement, a film coating mechanism is provided between the first bridge and the slitting mechanism. The film coating mechanism includes a rotatably configured film feeding and tensioning shaft, a film coating roller is provided below the film feeding and tensioning shaft, and a film tensioning roller is provided on the side of the film coating roller near the film feeding and tensioning shaft. The distance between the film tensioning roller and the aluminum strip is greater than the distance between the film coating roller and the aluminum strip. Several feeding rollers are provided on the front side of the film tensioning roller and the rear side of the film coating roller.

[0015] The principles and beneficial effects of this solution are as follows:

[0016] 1. In practical application, the aluminum coil is installed on the feeding and tensioning shaft. The head passes sequentially through the first bridge, slitting mechanism, edge-receiving mechanism, second bridge, and tensioning mechanism. As the aluminum strip passes through the slitting mechanism, it is cut into the required width. The scrap wires are manually passed through guide wheels and fixed on the edge-receiving and tensioning shaft. The tensioning mechanism then transmits the strip under tension to the oiling mechanism, where it undergoes electrostatic oiling. After oiling, it is wound onto the winding shaft, thus completing the unwinding process. During the feeding process, the bridge plates of the first and second bridges rise to form a horizontal bridge surface supporting the aluminum strip, facilitating feeding. After unwinding, the bridge plates of the first and second bridges are lowered, and the automated continuous slitting and oiling mechanism begins operation. The aluminum strip hangs suspended in the first and second feed pits to prevent straightening of the aluminum strip surface.

[0017] This solution integrates feeding, slitting, edge trimming, oiling, and winding mechanisms into a single, unified system. This effectively reduces the cumbersome operations of transferring aluminum strips between processes and lowers the risk of damage or deformation during the connection of aluminum strips between different devices. Utilizing an electrostatic oiling mechanism, the spray blade beam carries a negative charge, while the aluminum strip carries a positive charge. Based on the principle of electrostatic adsorption, the rust-preventive oil can be applied more evenly to the aluminum strip surface, solving the problem of uneven application in traditional oiling methods and improving the rust prevention effect and product quality. Simultaneously, the integrated design of the equipment improves space utilization, reduces the production floor space, and facilitates equipment layout and management within the workshop.

[0018] 2. The unloading tensioning shaft can be tightened according to the inner diameter of the aluminum coil, ensuring that the aluminum coil is stable and does not wobble during the unloading process, providing a foundation for smooth aluminum strip conveying. The setting of the pressure swing arm and pressure roller can, on the one hand, use the weight of the pressure roller itself to further tighten the aluminum coil, preventing the aluminum coil from loosening at the beginning of the unloading stage; on the other hand, as the outer diameter of the aluminum coil gradually decreases, the pressure swing arm can adaptively adjust the position of the pressure roller around the rotation point to always maintain effective pressure on the aluminum coil, ensuring the stability and continuity of the unloading process and improving the accuracy of aluminum strip conveying.

[0019] 3. The pinch roller assembly drives the aluminum strip forward with stable clamping force and rotation speed, providing continuous and stable power for the aluminum strip conveying and ensuring uniform conveying speed between different processes. The two first bridge plates of the first bridge can be raised to form a horizontal bridge surface during material feeding, greatly facilitating the feeding operation of the aluminum strip head, reducing feeding difficulty, and improving feeding efficiency. After feeding is completed, the bridge plates are lowered, and the aluminum strip hangs suspended in the material pit, avoiding frictional damage to the aluminum strip surface caused by continuous support from the bridge plates, effectively protecting the surface quality of the aluminum strip and preventing defects such as scratches. At the same time, the suspended aluminum strip retains sufficient adjustment margin, facilitating real-time adjustment of the conveying speed of various parts of the aluminum strip in conjunction with the system.

[0020] 4. The sliding design of the slitting knife holder on the slitting knife guide rail allows for flexible adjustment of the slitting knife spacing, meeting the slitting needs of aluminum strips of different widths and enhancing the equipment's versatility and processing flexibility. The design of the knife feed guide rail, knife feed slide, and knife change guide rail enables rapid knife replacement. While one slitting knife is working, another can be pre-tested off-line. When replacement is needed, the knife feed slide slide moves to align the knife change guide rail with the slitting knife guide rail, allowing for quick replacement of the original slitting knife holder and the newly tested one onto the production line. This eliminates the need for complex downtime adjustments, significantly reducing downtime, improving production efficiency, and increasing output per unit time.

[0021] 5. The edge-gathering drive unit rotates the edge-gathering tensioning shaft to wind up the waste edge wire. The guide cylinder drives the guide wheel to repeatedly rise and fall, ensuring that the waste edge wire is evenly wound onto the edge-gathering tensioning shaft during the winding process, avoiding accumulation and uneven winding of waste edge wire, and guaranteeing winding quality. When the maximum amount of waste edge wire is wound, it is cut off, and the edge-gathering tensioning shaft retracts, causing the wound waste edge wire to fall off automatically, achieving convenient unloading, improving the automation level of the edge-gathering process, reducing manual intervention, and lowering labor intensity.

[0022] 6. The second bridge plate of the second crossover bridge rises during material feeding, cooperating with the first crossover bridge to facilitate the smooth passage of the aluminum strip through multiple mechanisms and complete the feeding operation. After feeding, the bridge plate is lowered, and the aluminum strip hangs suspended in the second material pit, similar to the first crossover bridge. This effectively avoids surface scratches caused by continuous contact between the aluminum strip and the bridge plate, protecting the surface quality of the aluminum strip. Simultaneously, the second crossover bridge serves as a transition from the edge-gathering mechanism to the tensioning mechanism, ensuring the continuity of aluminum strip transmission and allowing for smooth connection between different processes, reducing problems such as jamming and deviation during the transmission process.

[0023] 7. The lifting drive precisely adjusts the height of the tension table according to the material, thickness, and winding requirements of the aluminum strip, thereby changing the pressure of the feed roller on the aluminum strip and achieving precise control of the aluminum strip tension. The removable limit ring on the feed roller can be replaced according to the width of the aluminum strip to ensure that the aluminum strip is always in the correct position during the conveying process and does not deviate. Through the action of the tension table, the aluminum strip is kept in a taut state before entering the winding mechanism, ensuring that the aluminum strip can be tightly and neatly wound on the winding shaft, improving the winding quality, avoiding winding defects such as loose aluminum strip and wrinkles, and improving the appearance quality and storage stability of the product.

[0024] 8. The take-up shaft is responsible for winding up the oiled aluminum strip, achieving the final product shape. Similar to the unwinding mechanism, the pressure arm and pressure roller above the take-up shaft apply pressure to the aluminum strip during winding, ensuring it adheres tightly to the take-up shaft and guaranteeing the tightness and uniformity of the winding. As winding progresses, the aluminum strip diameter gradually increases, and the pressure arm can adaptively adjust the position of the pressure roller to maintain effective pressure on the aluminum strip, preventing loosening or slippage during winding. This ensures the stability and reliability of the winding process, improving winding efficiency and product quality.

[0025] 9. When necessary, a coating mechanism can be used to coat the aluminum strip. The film unwinding tensioning shaft ensures the coating material remains stable during unwinding, preventing loosening or wrinkling. The film tensioning roller opens the coating material and applies tension, allowing it to adhere smoothly to the aluminum strip. The coating rollers press the coating material tightly onto the aluminum strip surface, completing the coating operation. The feeding roller assists in the smooth transport of the coating material and aluminum strip, preventing misalignment or jamming during the coating process. Coating effectively protects the aluminum strip surface from scratches and corrosion during subsequent handling, storage, and processing, extending the strip's lifespan, increasing product added value, and meeting the diverse needs of different customers.

[0038] Example 1:

[0039] like Figure 1 As shown, the aluminum coil slitting and oiling integrated machine includes, from right to left, a feeding mechanism 1, a first bridge 2, a film coating mechanism 3, a slitting mechanism 4, an edge-retracting mechanism 5, a second bridge 6, a tension mechanism 7, an electrostatic oiling mechanism 8, and a winding mechanism 9.

[0040] Combination Figure 2 As shown, the feeding mechanism 1 includes a feeding tension shaft 11 rotatably mounted on the frame, which is driven to rotate by a motor. A pressing swing arm 12 is rotatably mounted above the feeding tension shaft 11, and a pressing roller 13 is rotatably mounted on the free end of the pressing swing arm 12.

[0041] Combination Figure 3 As shown, a clamping roller assembly 21 is installed on one side of the feeding mechanism 1. The clamping roller assembly 21 is driven to rotate by a motor, and the spacing between the clamping roller assemblies 21 is adjusted by a cylinder. The clamping roller assembly 21 is used to clamp and feed the aluminum strip fixed on the feeding tensioning shaft 11 forward. Multiple feeding rollers 22 are rotatably arranged on the discharge end side of the clamping roller assembly 21, and the aluminum strip is conveyed to the first crossbridge 2 through these feeding rollers 22. The first crossbridge 2 includes a first material pit 25 and two first bridge plates 23. The ends of the two first bridge plates 23 that are far apart from each other are hinged to the frame. The free ends of the two first bridge plates 23 are arranged opposite each other and located in the first material pit 25. Multiple feeding rollers 22 are also rotatably arranged on the free ends of the first bridge plates 23 on the discharge end side of the first crossbridge 2, and the aluminum strip is conveyed to the coating mechanism 3 through these feeding rollers 22.

[0042] Combination Figure 4 As shown, the coating mechanism 3 includes a rotatably mounted film-releasing and tightening shaft 33. A coating roller 31 is positioned below the film-releasing and tightening shaft 33. A film-stretching roller 32 is rotatably mounted on the feed side of the coating roller 31. Several feeding rollers 22 are positioned in front of the film-stretching roller 32, which transport the aluminum strip from the first crossbridge 2 to the coating roller 31. Several feeding rollers 22 (not shown in the figure) are also rotatably mounted behind the coating roller 31, which transport the aluminum strip to the slitting mechanism 4. The coating mechanism 3 is an optional feature, activated when coating is required.

[0043] Combination Figure 5 and Figure 6 As shown, the slitting mechanism 4 includes a slitting knife guide rail 43 and a slitting knife holder 40 slidably mounted on the slitting knife guide rail 43. A slitting knife is rotatably mounted on the slitting knife holder 40. The slitting knife includes a knife shaft 41 and multiple knife bodies 42 detachably mounted on the knife shaft 41. The spacing of the knife bodies 42 can be adjusted as needed. A knife feeding guide rail 44 is provided on the outer side of the slitting knife guide rail 43 along the aluminum strip conveying direction. A knife feeding slide plate 45 is slidably mounted on the knife feeding guide rail 44. Two tool changing guide rails 46 that can dock with the slitting knife guide rail 43 are mounted on the knife feeding slide plate 45. The slitting knife holder 40 and the slitting knife are pushed out as a whole onto the knife feeding slide plate 45. By sliding the knife feeding slide plate 45 so that another slitting knife holder 40 pre-prepared on another tool changing guide rail 46 is aligned with the slitting knife guide rail 43, the slitting knife holder 40 to be replaced and the slitting knife attached to it can be pushed into the slitting knife guide rail 43 as a whole, thus achieving tool changing.

[0044] Combination Figure 7 As shown, the edge-gathering mechanism 5 includes a conveying assembly, which includes several feeding rollers 22. These feeding rollers 22 convey the aluminum strip from the slitting mechanism 4 to the edge-gathering mechanism 5 and then forward to the second crossbridge 6. An edge-gathering tensioning shaft 51 is vertically arranged on the outer side of these feeding rollers 22. The edge-gathering tensioning shaft 51 is connected to an edge-gathering drive component, which drives the edge-gathering tensioning shaft 51 to rotate. In this embodiment, the edge-gathering drive component is a motor. A wire-guided cylinder 52 is vertically arranged on one side of the edge-gathering tensioning shaft 51. A wire-guided wheel 54 is fixed on the piston rod 53 of the wire-guided cylinder 52, and the wire-guided wheel 54 has a wire-guided hole 55 for the edge wire to pass through. The slid aluminum strip is conveyed forward to the second crossbridge 6 by the feeding rollers 22 in the slitting mechanism 4. After passing through the second crossbridge 6, it is conveyed to the tension mechanism 7, where the waste edge wire is wound and wound by the edge-gathering tensioning shaft 51.

[0045] Combination Figure 8 As shown, the second bridge 6 includes a second material pit 62, and a second bridge plate 61 is provided in the second material pit 62. The feeding end of the second plate is hinged to the frame and communicates with the feeding roller 22 in the edge-receiving mechanism 5.

[0046] Combination Figure 9 As shown, the tension mechanism 7 includes a vertically sliding tension table 71. A lifting drive unit, using a cylinder, is connected to the top of the tension table 71 to drive its lifting and lowering. A feeding roller 72 is located on the front side of the tension table 71, and a limit ring 73 is detachably mounted on the feeding roller 72. The aluminum strip from the second crossbridge 6 is conveyed to the tension table 71 via the feeding roller 72. Multiple feeding rollers 22 (not shown in the figure) are also provided on the discharge side of the tension table 71. These feeding rollers 22 continue to convey the aluminum strip forward to the winding mechanism 9 for winding. Figure 10 As shown, the winding mechanism 9 includes a winding tension shaft 91, and a pressure arm 12 and a pressure roller 13 are also provided above the winding tension shaft 91. The forward-conveyed aluminum strip is kept taut by the pressure of the tension table 71 so that it can be wound up for subsequent winding.

[0047] Before winding, the aluminum strip passes under the electrostatic oiling mechanism 8, where it is oiled. The electrostatic oiling mechanism 8 includes a charging system, an oiling guide rail 81 positioned above the aluminum strip, and an oiling box 82 slidably connected to the oiling guide rail 81. A spray blade beam (not shown) is installed inside the oiling box 82. The charging system provides a negative charge to the spray blade beam and a positive charge to the aluminum strip. Specifically, the spray blade beam can be negatively charged by directly connecting it to the negative terminal of the charging system's power supply. The aluminum strip can be positively charged using existing methods, such as using slip rings or brushes to connect the charging system and the aluminum strip, allowing the moving aluminum strip to connect to the positive terminal of the charging system's power supply. Alternatively, a positive charge can be provided to the aluminum strip using an induction coil. When the equipment is not in use, the oiling box 82 slides off the production line along the oiling guide rail 81.

[0048] In practical application, the aluminum coil is hoisted to the unloading tensioning shaft 11. The tensioning force of the unloading tensioning shaft 11 (hydraulic tensioning is used in this embodiment) is adjusted according to the inner diameter of the aluminum coil to tighten it, thus securing the aluminum coil stably on the unloading tensioning shaft 11. The head of the aluminum coil is manually passed sequentially through the pinch roller group 21, the first crossover 2, the slitting mechanism 4, the edge-receiving mechanism 5, the second crossover 6, and the tension mechanism 7. When the aluminum strip passes through the slitting mechanism 4, it is cut into the required width. The slit waste wires are manually passed through the guide wheel 54 and fixed on the edge-receiving tensioning shaft 51. They are then conveyed under tension by the tension mechanism 7 to the area below the electrostatic oiling mechanism 8, where electrostatic oiling is applied. After oiling, the strip is wound onto the winding tensioning shaft 91, thus completing the unwinding process. During the aluminum strip feeding, the first bridge plate 23 of the first crossover 2 and the second bridge plate 61 of the second crossover 6 are raised to a horizontal position to support the aluminum strip and facilitate feeding.

[0049] After uncoiling, the drive tensioning shaft 11 slowly rotates the aluminum coil to release it. The motor of the pinch roller assembly 21 is started, and the roller speed is adjusted according to the release speed. The clamping force is also adjusted according to the aluminum strip thickness to stably clamp the aluminum strip. During the release process, as the outer diameter of the aluminum coil decreases, the position of the pressure arm 12 is adjusted in a timely manner to ensure that the pressure roller 13 always maintains good contact with the surface of the aluminum coil and provides appropriate pressure, preventing the aluminum coil from loosening during release. After uncoiling, the first bridge plate 23 and the second bridge plate 61 are lowered, allowing the aluminum strip to hang naturally in the first and second feed pits 25 and 62, and be conveyed forward in a relaxed state.

[0050] When the aluminum strip passes through the coating mechanism 3, if coating is required, the film feeding tensioning shaft 33, the film tensioning roller 32, and the coating roller 31 are driven to rotate. The motor speed is adjusted to ensure that the coating material is smoothly released from the film feeding tensioning shaft 33, tensioned by the film tensioning roller 32, and precisely bonded to the aluminum strip at the coating roller 31. The pressure between the film tensioning roller 32 and the coating roller 31, as well as the rotation speed of the coating roller 31, are adjusted according to the thickness of the coating material and the material of the aluminum strip to ensure coating quality and avoid problems such as bubbles and wrinkles. The coated aluminum strip is then conveyed to the slitting mechanism 4 by the feeding roller 22 behind the coating roller 31. If coating is not required, it is directly conveyed forward to the slitting mechanism 4, where it is slitted by a rotating slitting knife.

[0051] The slit aluminum strip is conveyed forward. During the uncoiling process, the waste edge wires generated from slitting are manually passed through the guide wheel 54 and fixed on the edge tightening shaft 51. Therefore, while being conveyed, the waste edge wires are wound around the edge tightening shaft 51 by rotation. The guide cylinder 52 is extended and retracted by a solenoid valve, causing the guide wheel 54 to move up and down to guide the edge wires to wind evenly. After a certain amount is wound, the edge wires are manually cut, and the edge tightening shaft 51 is controlled to contract, causing the edge wires to fall off.

[0052] The aluminum strip enters the second bridge 6 under the push of the feeding roller 22 of the edge-receiving mechanism 5. The aluminum strip hangs naturally in the second material pit 62, and is then conveyed to the tension mechanism 7 by the feeding roller 22. The aluminum strip enters the tension table 71 through the feeding roller 72. The limiting ring 73 on the feeding roller 72 prevents the aluminum strip from deviating during transmission. The tension of the aluminum strip is adjusted by pressing down the tension table 71. After tension adjustment, the aluminum strip is conveyed to the electrostatic oiling mechanism 8 by the feeding roller 22 on the discharge side of the tension table 71.

[0053] The charging system is activated, and appropriate voltage and current parameters are set to make the spray blade beam negatively charged and the aluminum strip positively charged according to the selected method (slip ring, brush, or induction coil connection). The aluminum strip passes under the electrostatic oiling mechanism 8 driven by the feed roller 22. The anti-rust oil sprayed by the spray blade beam is ionized under the action of static electricity to form an oil mist that is evenly coated on the surface of the aluminum strip.

[0054] After being coated with oil, the aluminum strip is conveyed forward by the feeding roller 22 and wound onto the winding tension shaft 91. As the roll diameter increases, the position of the pressure swing arm 12 is adjusted in a timely manner to ensure that the pressure of the pressure roller 13 is appropriate.

[0055] When a tool change is required, place another set of pre-adjusted slitting cutters on a tool change guide 46 on the tool feed slide 45. Then, slide the tool feed slide 45 until the empty tool change guide 46 is aligned with the slitting cutter guide 43. Next, push the slitting cutter holder 40 and the entire slitting cutter from the production line onto the empty tool change guide 46 on the tool feed slide 45. Then, slide the tool feed slide 45 to align the pre-adjusted slitting cutter holder 40 on the other tool change guide 46 with the slitting cutter guide 43. Finally, push the slitting cutter holder 40 and the entire slitting cutter on the tool feed slide 45 onto the slitting cutter guide 43 and secure it, thus completing the tool change.
