Description

Technical Field

[0001] This utility model relates to the field of die-cutting machines, specifically a cross asynchronous flatbed die-cutting machine. Background Technology

[0002] Flatbed die-cutting machines are a widely used type of post-printing processing equipment, mainly used for precise cutting and creasing of paper, cardboard, corrugated cardboard, and some plastic sheets. Traditional die-cutting machines mostly use a single feeding and die-cutting method, which has the following shortcomings:

[0003] 1. Low feeding accuracy: Existing paper feeding methods generally use synchronous chains or belts, which are prone to feeding deviation after long-term operation, resulting in inaccurate die-cutting position.

[0004] 2. Simple structural layout: The feeding and discharging directions of common die-cutting machines are mostly arranged in a straight line, which is not conducive to space utilization and also limits the combination of asynchronous feeding and multi-directional feeding.

[0005] 3. Insufficient automation: Some equipment relies on manual intervention in the feeding, die-cutting, and receiving stages, making it difficult to achieve high efficiency and stable production.

[0006] 4. Low level of safety and control: The electrical control system of traditional die-cutting machines is relatively simple, and the ability to adjust the stamping pressure, feeding speed and die-cutting accuracy is limited, which affects the processing quality.

[0007] Based on the above problems, a cross asynchronous flatbed die-cutting machine is proposed. It achieves the perpendicular intersection of the feeding and pulling directions through a unique cross arrangement. Combined with the optimized arrangement of the electronic control system and stamping components, it significantly improves the die-cutting accuracy, ease of operation and production efficiency.

[0015] Preferably, a buffer roller assembly is provided between the material pulling frame and the lower die base to reduce vibration during the material pulling process.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. High space utilization: The feeding rack and the pulling rack are arranged on both sides of the lower mold base to form a "cross" structure, which makes the overall structure of the equipment compact, occupies little space, and is suitable for a variety of production scenarios.

[0018] 2. Precise feeding: The asynchronous feeding and pulling of the workpieces is achieved through the cooperation of the feeding rack and the pulling rack, which can avoid the displacement of the workpieces during the die-cutting process and improve the die-cutting accuracy.

[0019] 3. Easy to operate: The control panel is located on the lower side of the feeding rack, which makes it easy for the operator to directly adjust parameters and monitor the operating status at the feeding position.

[0020] 4. Stable operation: The stamping components are located between the upper and lower die bases, ensuring uniform stamping pressure and a smooth die-cutting process.

[0021] 5. Electrical control safety: The electrical box is located below the equipment, which lowers the overall center of gravity, enhances operational stability, and allows for a more reasonable layout of electrical wiring, facilitating inspection and maintenance.

[0022] 6. High applicability: It can be adapted to workpieces of different thicknesses and materials, and has a wide range of applications.

[0023] 7. High level of automation: Combined with the control system and structural layout, continuous automation of feeding, die-cutting and receiving can be achieved, improving production efficiency. Attached Figure Description

[0027] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. In the embodiments of the present utility model, the different types of cross-sectional lines are not labeled according to national standards, nor do they specify material requirements for the components; they are used to distinguish the cross-sectional views of the components in the drawings.

[0028] Please see Figure 1 A cross asynchronous flatbed die-cutting machine includes an upper die base 5, a lower die base 7 installed at the lower end of the upper die base 5, and a stamping assembly 4 between the upper die base 5 and the lower die base 7. A material pulling frame 6 is installed on the right side of the lower die base 7, and a feeding frame 3 is provided on the left side of the lower die base 7. A control panel 2 is installed on the lower right side of the feeding frame 3. An electrical box 1 is provided at the bottom of the cross asynchronous flatbed die-cutting machine.

[0029] The stamping assembly 4 includes a hydraulic cylinder and a stamping head. The hydraulic cylinder is installed inside the upper die base 5, and the stamping head is movably connected above the lower die base 7.

[0030] The feed rack 3 includes a conveyor roller group and a limiting plate. The conveyor roller group is used to drive the workpiece to move in the direction of the lower mold base 7, and the limiting plate is used to prevent the workpiece from deviating.

[0031] The feeding frame 6 is equipped with guide rollers and take-up rollers. The guide rollers are used to correct the feeding direction, and the take-up rollers are used to collect the finished products.

[0032] The electrical box 1 is equipped with a PLC controller and a frequency converter driver to achieve coordinated control of feeding, stamping and pulling actions.

[0033] Among them, a buffer roller group is provided between the material pulling frame 6 and the lower die base 7 to reduce vibration during the material pulling process.

[0034] It should be noted that, firstly, the operator places the cardboard or sheet material to be processed onto the conveyor roller assembly of the feed rack 3. The conveyor roller assembly rotates under the command of the control panel 2, driving the workpiece towards the lower die base 7. A limiting plate ensures the workpiece remains in a straight line during transport, preventing lateral deviation. Simultaneously, a support platform provides support from below, allowing the workpiece to smoothly enter the working area of ​​the lower die base.

[0035] When the workpiece reaches the worktable of the lower die holder 7, the locating pins precisely position it, ensuring a fixed relative position between the workpiece and the die-cutting die. At this time, the control system sends a command through the PLC to drive the hydraulic cylinder in the upper die holder 5. The hydraulic cylinder pushes the stamping assembly 4 downward, and the stamping head closes with the die on the lower die holder, performing die-cutting or creasing on the workpiece. Because the upper and lower die holders are made of high-strength alloy steel, and the stamping pressure is adjusted by the control panel, it can ensure that the cutting edges are neat and the creasing depth is consistent.

[0036] After die cutting is completed, the punch head automatically returns to its initial position, and the workpiece is released from the lower die holder. At this time, the material puller 6 located on the other side of the lower die holder begins to work. The guide rollers in the material puller guide the workpiece to the correct direction, and then the winding rollers or conveying mechanism pull the processed workpiece out of the lower die holder area, realizing the conveying and collection of finished products.

[0037] Throughout the process, control panel 2 plays a crucial role. Operators can set the feeding speed, punching force, and pulling speed via the control panel. The system automatically coordinates the actions of each stage according to the set parameters, ensuring the continuity and stability of the die-cutting process. The built-in fault alarm module on the control panel can promptly issue alerts in abnormal situations, ensuring the safety of both the equipment and the operator.

[0038] Electrical control box 1 serves as the core of the system's electrical control, internally equipped with a PLC controller and a frequency converter. The PLC controller receives instructions from the control panel and converts them into control signals for various actuators such as motors and hydraulic cylinders. The frequency converter adjusts the speed of motors such as the conveyor roller group and the pulling roller group, thereby achieving asynchronous control of feeding and pulling. The bottom-mounted arrangement of the electrical control box effectively lowers the equipment's center of gravity, improves operational stability, and facilitates daily maintenance and heat dissipation.

[0039] Furthermore, the machine's cross-shaped arrangement, where the feeding and pulling directions intersect at 90°, offers significant advantages. In traditional linear die-cutting machines, the workpiece requires a relatively long straight-line space from feeding to output, while the cross-shaped arrangement effectively shortens the workpiece's travel path, resulting in a smaller overall footprint and a more compact layout. Simultaneously, the cross-shaped arrangement facilitates the splitting of workpiece processing in different directions, enhancing production flexibility.
