Description

Technical Field

[0001] This invention relates to the field of production and processing equipment technology for color-coated aluminum coils, and specifically to a color-coated aluminum coil cutting device. Background Technology

[0002] The information disclosed in the background section of this invention is intended only to enhance the understanding of the overall background of the invention and is not necessarily to be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art.

[0003] Color-coated aluminum coils, as a type of surface-treated aluminum alloy coil, are widely used in building decoration, home appliance manufacturing, transportation, and other fields due to their excellent corrosion resistance, decorative properties, and processing performance. In practical applications, wide-width color-coated aluminum coils need to be cut into narrow-width coils of different widths or processed into irregularly shaped sheets according to specific requirements. This necessitates efficient and precise cutting and slitting equipment.

[0004] Currently, the cutting equipment for color-coated aluminum coils mainly uses mechanical blade cutting or traditional laser cutting methods. Mechanical blade cutting has the following drawbacks: First, the blades wear out quickly, requiring frequent replacement and resulting in high maintenance costs; second, burrs and curled edges are easily generated during the cutting process, affecting product quality; third, adjusting the cutting width requires stopping the machine to replace the blades or adjust the mechanical structure, making it difficult to dynamically change the cutting width in real time during production, resulting in poor production flexibility and failing to meet the flexible production needs of small batches and multiple specifications.

[0005] Therefore, developing a color-coated aluminum coil cutting device that can dynamically adjust the cutting width and perform the cutting simultaneously with the slitting process has become an urgent technical problem to be solved in this field. Summary of the Invention

[0006] In view of the problems existing in the prior art, the purpose of this invention is to provide a color-coated aluminum coil cutting device, which aims to solve the technical problem that the existing color-coated aluminum coil cutting is difficult to dynamically adapt to multi-specification coiling and irregular shape processing in continuous processing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A color-coated aluminum coil cutting device includes a frame, on the top of which a substrate roll, a first guide roll, and a second guide roll are rotatably mounted in sequence. A cutting frame is provided above the space between the first guide roll and the second guide roll. An arc-shaped mounting frame with the second guide roll as its center is provided between the top of the cutting frame and the frame.

[0009] The cutting frame is equipped with a guide drive assembly, on which two or more slides are mounted, and on which corresponding laser cutting units are mounted;

[0010] The arc-shaped mounting frame has one more cutting roll than the number of laser cutting units distributed on it; the substrate roll is used to wind the substrate color-coated aluminum coil, and the cutting roll is used to wind the corresponding cut color-coated aluminum coil.

[0011] The guide drive assembly, substrate roll, and cut roll are all equipped with corresponding power drive devices.

[0012] Preferably, the guide drive assembly includes a guide optical shaft and a lead screw assembly, wherein the lead screw sleeve of the lead screw assembly is connected and fixed to the slide block, and the slide block is provided with a slide sleeve adapted to the guide optical shaft.

[0013] Preferably, the first guide roller is also used to tension the color-coated roll located between the first guide roller and the second guide roller.

[0014] Preferably, the first guide roller is rotatably mounted on the slide plate at both ends, and the slide plate is slidably mounted on both sides of the frame; the slide plate is also connected to the output end of the tensioning drive device.

[0015] Preferably, the frame has mating holes for the first guide roller to pass through and sliding grooves for the slide plate to slide on both sides, and the slide plate is provided with a slider that matches the sliding groove.

[0016] The present invention has at least the following beneficial effects:

[0017] This invention breaks away from the existing technology of separating cutting and slitting or directly cutting color-coated aluminum coils using mechanical cutting methods. It achieves real-time cutting and slitting while the substrate color-coated aluminum coil is unrolled. After the substrate color-coated aluminum coil is unrolled from the substrate roll, it remains under closed-loop tension control. The first and second guide rollers provide a stable cutting environment and continuous, stable tension. The cutting frame cuts in real-time while the substrate is under tension, and the cut substrate is immediately and synchronously wound up by the cut-out roll on the arc-shaped mounting frame. There is no lag in the conveying path, and the substrate has no relaxation phase throughout the process, completely avoiding cutting deviations caused by wrinkles or offsets. Furthermore, continuous tension constraint prevents coating scratches when cutting thin substrates, thereby improving coating integrity.

[0018] Meanwhile, the arc-shaped mounting frame uses the second guide roller, i.e., the turning point of the cut substrate, as the center, ensuring that the distance between each cut roll and the turning point is exactly equal. This ensures that the path length of the cut substrate from the turning point to the slitting roll is consistent. Combined with the tension adjustment of the first guide roller, real-time matching of cutting tension and slitting tension can be achieved. This improves the uniformity of roll tension during slitting, resulting in no wrinkles or tensile deformation during subsequent unwinding, thereby increasing the pass rate of downstream processing steps.

[0019] This device uses a guide drive assembly to drive the slide block, which in turn drives the laser cutting unit to slide laterally. The spacing between adjacent laser cutting units can be adjusted in real time during production, allowing for dynamic changes in cutting width without stopping the machine. This dynamic adjustment capability not only quickly responds to production needs of different specifications but also, through the coordination of the lateral sliding of the laser cutting unit and the substrate conveying, directly completes the cutting of irregularly shaped color-coated aluminum sheets. This eliminates the need for additional irregular-shaped processing stations, significantly improving the equipment's adaptability to diverse production tasks. Attached Figure Description

[0025] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0026] Figures 1 to 3 A color-coated aluminum coil cutting device is presented, including a frame 100. A substrate roll 200, a first guide roll 300, and a second guide roll 400 are rotatably mounted on the top of the frame 100 in sequence. A cutting frame 500 is arranged above the first guide roll 300 and the second guide roll 400. An arc-shaped mounting frame 510 with the second guide roll 400 as the center is arranged between the top of the cutting frame 500 and the frame 100.

[0027] The cutting frame 500 is provided with a guide drive assembly 800, on which two or more slides 910 are mounted. Each slide 910 is equipped with a corresponding laser cutting unit 900. The laser cutting unit 900 can be an adapted laser cutter. The structure of the laser cutter is a mature existing technology, which should be understood by those skilled in the art, and will not be elaborated further here.

[0028] The arc-shaped mounting frame 510 has one more cutting roll 600 than the number of laser cutting units 900; the substrate roll 200 is used to wind the substrate color-coated aluminum roll 700, and the cutting roll 600 is used to wind the corresponding cut color-coated aluminum roll 710.

[0029] The guide drive assembly 800, the substrate roll 200, and the cutting roll 600 are all equipped with corresponding power drive devices, which can specifically be corresponding and compatible motors. The specific structure of the guide drive assembly 800 is as follows: it includes a guide optical shaft 810 and a lead screw assembly. The lead screw sleeve 920 of the lead screw assembly is connected and fixed to the slide block 910, and the slide block 910 is provided with a slide sleeve adapted to the guide optical shaft 810.

[0030] This device can cut the substrate color-coated aluminum coil 700 on the substrate roll 200 into different specifications, and then wind them onto their respective cut rolls 600. Since the laser cutting unit 900 can slide left and right, dynamic real-time control of the specifications of the cut color-coated aluminum coil 710 can be achieved. Moreover, the laterally sliding laser cutting unit 900 can not only be used for the specification (width) control of the cut color-coated aluminum coil 710, but also for the processing and slitting of irregularly shaped color-coated aluminum sheets.

[0031] The cut rolls 600 are distributed and installed on the arc-shaped mounting frame 510 with the second guide roll 400 as the center, which ensures that the cutting of the color-coated aluminum coil 710 is carried out synchronously, thereby ensuring dynamic real-time control of the specifications of the cutting of the color-coated aluminum coil 710.

[0032] In order to ensure the flatness of the cut and thus the cutting quality of the laser cutting unit 900, the first guide roller 300 is also used to tension the color-coated roll located between the first guide roller 300 and the second guide roller 400.

[0033] The specific implementation is as follows: the first guide roller 300 is rotatably mounted on the slide plate 310 at both ends, and the slide plate 310 is slidably mounted on both sides of the frame 100; the slide plate 310 is also connected to the output end of the tensioning drive device 320, which can be a linear telescopic component such as an electric cylinder or a hydraulic cylinder. The frame 100 has mating holes for the first guide roller 300 to pass through and sliding grooves 330 for the slide plate 310 to slide on both sides, and the slide plate 310 is provided with a slider adapted to the sliding groove 330.

[0034] Of course, in order to further ensure the smooth progress of dynamic cutting, a corresponding fine-tuning tension roller can also be set between the second guide roller 400 and the corresponding cut roll 600. It is not shown in the figure, but it is easy to implement and should be understood by those skilled in the art. It will not be elaborated further here.
