Description

Technical Field

[0001] This utility model relates to the technical field of creasing, cutting and rewinding machines, specifically a creasing, cutting and rewinding machine. Background Technology

[0002] In the field of coil processing, when processing large-diameter coils into finished products with specific shapes, such as those with regular or irregular perforated patterns, irregular edges, or stepped cut edges, not only is it necessary to cut the coil, but also to remove excess material, resulting in waste. Traditional processing equipment often leaves waste tightly adhered to the finished coil after shaping, making separation difficult. If not cleaned promptly, this waste can affect the accuracy of subsequent processing, leading to deviations in the finished product's shape. Furthermore, accumulated waste can easily entangle the equipment's transmission components, causing coil conveying jams, reducing processing efficiency, and even damaging the equipment. Moreover, existing equipment does not effectively integrate the cutting and waste removal processes in its process design, making waste removal complex and inefficient, failing to meet the demands of high-precision, high-efficiency shape processing in industrial production.

[0003] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-2 In this embodiment of the utility model, an indentation, cutting and rewinding machine achieves continuous indentation, cutting, waste cleaning and rewinding of roll material through integrated design, solving the problems of poor process connection and difficult waste cleaning in traditional equipment.

[0033] The creasing, cutting, and rewinding machine includes a frame 1. Along the material conveying direction, the frame 1 is sequentially equipped with a feeding mechanism 2, a primary creasing assembly 3, a first cutting assembly 4, a secondary creasing assembly 5, a waste material cleaning assembly 6, a second cutting assembly 7, and a rewinding mechanism 8. All components are mechanically connected via the frame 1, forming a complete processing line.

[0034] The feeding mechanism 2 includes a feeding frame 9, on which a feeding shaft 10 and a feeding power component are mounted. The feeding shaft 10 is used to mount large-diameter rolls of material, and the feeding power component (such as a motor) drives the feeding shaft 10 to rotate, thereby achieving continuous feeding of the rolls. The feeding shaft 10 is usually equipped with a tension control device (such as a magnetic powder brake) to ensure stable tension during the feeding process and avoid the impact of tension fluctuations on subsequent processing accuracy.

[0035] The primary indentation assembly 3 is mounted on the frame 1 and includes a first support bracket 11, an indentation roller 12, an indentation power component, and a spacing adjustment structure 13. The outer circumferential surface of the indentation roller 12 has indentation patterns. Driven to rotate by the indentation power component (such as a motor), it forms indentation lines of a predetermined depth on the surface of the rolled material upon contact, providing a guiding path for subsequent cutting. The spacing adjustment structure 13 (such as a lead screw and nut pair or a slide rail and slider mechanism) can adjust the contact pressure between the indentation roller 12 and the rolled material to adapt to the processing requirements of rolled materials of different thicknesses.

[0036] The first cutting assembly 4 is installed downstream of the primary creasing assembly 3 and includes a second support bracket 14, a rotatable cutting roller 15 with cutting blades on its outer circumference, a cutting power component, and a positioning adjustment structure 16. The cutting roller 15 is driven to rotate by the cutting power component (such as a motor), and its cutting blades cut the roll material along the creasing line to form a waste area to be separated (such as edge material or hollowed-out parts). The positioning adjustment structure 16 (such as a slide rail slider mechanism or a lead screw and nut pair) can adjust the lateral position of the cutting roller 15 to adapt to the cutting requirements of roll materials of different widths.

[0037] The secondary creasing assembly 5 has a similar structure to the primary creasing assembly 3 and is located downstream of the first cutting assembly 4. Its function is to creasing the cut roll material again. By adjusting the creasing depth or position of the creasing roller 12, the connection between the waste area and the finished roll material is further weakened, which facilitates subsequent waste removal.

[0038] The waste cleaning assembly 6 includes a third support bracket 17, a blowing device 18, and an air nozzle 19. The third support bracket 17 is mounted on the frame 1, and the blowing device 18 (such as a blower) is fixed on the third support bracket 17 to generate compressed airflow. At least one air nozzle 19 is connected to the blowing device 18, and its spray direction is towards the waste area on the rolled material. When the rolled material passes under the air nozzle 19, the high-pressure airflow acts on the waste area, using the impact force of the airflow to separate the waste from the finished rolled material. The frame 1 has a waste collection box 20 in the area below the waste cleaning assembly 6, which adopts a pull-out or detachable structure for easy periodic cleaning of the collected waste.

[0039] The second cutting assembly 7 is installed downstream of the waste cleaning assembly 6 and includes a blade holder 21, a movable cutter 22, and a cutting power component. The blade holder 21 is fixed to the frame 1, and the movable cutter 22 cooperates with the blade holder 21. Driven by the cutting power component (such as a cylinder or motor), it reciprocates along the direction perpendicular to the roll material conveying direction to achieve lateral cutting of the roll material and form a finished roll material segment of a predetermined length.

[0040] The winding mechanism 8 is installed downstream of the second cutting assembly 7 and includes a winding bracket 23, a winding shaft 24, and a winding power component. The winding shaft 24 is rotatably mounted on the winding bracket 23 and is driven to rotate by the winding power component (such as a motor). It is adapted to receive the roll segments cut by the second cutting assembly 7 and rewind them into small-diameter finished products. The winding shaft 24 is usually equipped with a torque control device (such as a frequency converter) to ensure uniform tension during the rewinding process and prevent wrinkles or loosening of the finished roll.

[0041] Among them, the blowing device 18 of the waste cleaning component 6 has two working modes: continuous blowing and intermittent blowing.

[0042] In continuous blowing mode, the blowing device 18 continuously operates, outputting compressed airflow. The airflow is guided by the blowing device 18 to the integrated air nozzle 19 and sprayed onto the waste area of ​​the rolled material. The orientation and angle of the air nozzle 19 are calibrated to concentrate the airflow on the waste area as much as possible, reducing the impact on the finished rolled material. Simultaneously, the airflow output by the blowing device 18 can be adjusted according to the material of the rolled material and the condition of the waste adhesion, reducing the possibility of impact deformation on the surface of the rolled material while ensuring effective separation of the waste. This mode is suitable for continuous processing scenarios with high waste generation frequency and the need for real-time cleaning.

[0043] The intermittent blowing mode operates in conjunction with sensors and a control module. Sensors (such as photoelectric sensors and proximity sensors) are placed along the roll material conveying path to monitor the location of the waste area in real time (the waste material differs from the finished roll material in edge structure (e.g., height difference, light transmittance difference, cutting separation line, etc.)). When the sensor detects that the waste area has moved below the air nozzle 19, it transmits a signal to the control module, which then starts the blowing device 18. After the waste material is cleaned and separated, the sensor detects that the waste material has detached, and the control module stops the blowing device 18. This mode reduces equipment energy consumption while achieving the waste material cleaning function and is suitable for processing conditions with frequent waste material cleaning requirements.

[0044] Working principle:

[0045] Large-diameter rolls of material are conveyed to the primary creasing assembly 3 via the feeding mechanism 2. After initial creasing, the material enters the first cutting assembly 4, forming a waste area. Subsequently, the rolls enter the secondary creasing assembly 5, where the waste area is further weakened. Then, through the airflow of the waste cleaning assembly 6, the waste is separated from the rolls and falls into the waste collection box 20. The cleaned rolls are cut to predetermined lengths by the second cutting assembly 7 and finally rewound into small-diameter finished products via the winding mechanism 8. The entire process, through the coordinated operation of each assembly, achieves continuous processing of the rolls from large to small diameter, and from raw materials to finished products.

[0046] Beneficial effects:

[0047] Highly efficient waste removal: Through a combination of processes including primary creasing, cutting, and secondary creasing, the connection between the waste area and the finished roll material is weakened. Combined with airflow cleaning, this significantly improves waste separation efficiency and reduces the impact of residual waste on subsequent processing.

[0048] Improved processing accuracy: All components are integrated through the frame 1, and the roll material conveying path is fixed, reducing positional deviations caused by process changes; the adjustment structure of the creasing roller 12 and the cutting roller 15 can precisely control the processing parameters to ensure the shape and size accuracy of the finished product.

[0049] Easy equipment maintenance: The waste collection box 20 adopts a pull-out or detachable design, which makes it easy to clean up waste; the support brackets and adjustment structures of each component are modularly designed, which reduces the difficulty and cost of equipment maintenance.

[0050] Improved production efficiency: Continuous processing reduces the transfer time of roll materials between processes, and automated waste disposal reduces manual intervention, resulting in a significant improvement in overall production efficiency.

[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
