Description

Technical Field

[0001] This utility model relates to the technical field of die-cutting machines, and in particular to a flat-pressing and creasing die-cutting machine for pearl cotton. Background Technology

[0002] Polyethylene foam, also known as EPE pearl cotton, is a non-crosslinked closed-cell structure and a new type of environmentally friendly packaging material. It is composed of countless independent air bubbles generated by the physical foaming of low-density polyethylene resin.

[0003] While existing creasing and die-cutting machines possess relatively mature technology, unexpected indentations, dents, or bubble ruptures often occur on the surface of the EPE foam during continuous production, affecting its appearance. These problems primarily stem from uneven worktable surfaces or the presence of foreign objects (such as small particles), causing localized deformation due to pressure. Excessive die-cutting pressure, exceeding the compressive strength of the EPE foam, can also lead to bubble rupture and dents. Uneven bubble distribution within the material itself can also cause deformation in weaker areas under pressure. The type of EPE foam selected based on the process can be optimized, but maintaining a flat worktable is crucial for routine production.

[0004] The existing technology CN202420162898.1 describes a flatbed creasing and cutting machine for pearl cotton. This device allows workers to easily replace the flatbed creasing template, thereby increasing the speed of template replacement, reducing the tediousness of template replacement steps, and alleviating the workload of workers. However, this device does not provide instructions on how to keep the table flat, especially since most current equipment is open-type. During die-cutting, pearl cotton inevitably produces defective products due to foreign objects on the table.

[0005] In the current production of yarn, cotton, and other products, negative pressure devices are often installed to absorb dust and other impurities from the surrounding environment. This approach offers some insights for EPE foam flatbed creasing and die-cutting machines. However, EPE foam is a different material, and impurities generated during processing tend to adhere to the work surface; therefore, timely cleaning of these impurities is more important. Utility Model Content

[0006] The purpose of this invention is to provide a flatbed die-cutting machine for pearl cotton that can ensure the flatness of the work surface during die-cutting.

Each clamping block includes a bottom block and a limiting block. The bottom block is detachably mounted on the horizontal steel plate, and the limiting block is detachably mounted on the bottom block.

[0011] Furthermore, the bottom block is slidably connected to the horizontal steel plate via a T-slot, and the height of the limiting block is adjustable, with an adjustment range of 30-80mm.

[0017] The technical effects and advantages of this utility model: The specific implementation method of this pearl cotton flatbed creasing and die-cutting machine has many advantages, mainly reflected in the following aspects:

[0018] I. High processing precision and stable product quality: The guiding structure of the die-cutting unit consists of a mounting base and a guide slide rod. The guide slide rod slides through the sliding hole of the mounting base, and its bottom end is fixedly connected to the top of the die-cutting cutter, ensuring the stability of the cutter's up-and-down movement and reducing offset during the die-cutting process. In the moving support assembly, the screw and the internal thread seat are threaded together, and the horizontal slide and the horizontal slide rod are clearance-fitted (0.05-0.1mm), ensuring that the straightness of the carrier platform's movement is ≤0.5mm / m, making the die-cutting carrier platform more stable during movement and improving the accuracy of the die-cutting position. The power system uses a servo motor (positioning accuracy ±0.01mm) and is controlled by a PLC. The moving speed and dwell time can be preset, and it is linked with the cylinder action to achieve precise control, reducing product errors caused by manual operation or unstable equipment operation, and ensuring stable product quality.

[0019] II. High adaptability, meeting diverse needs: The die-cutting support table includes a base block and a limiting block. The base block slides to the horizontal steel plate via a T-slot, while the limiting block is fixed to the base block with bolts. The spacing between the blocks is adjustable (range 50-300mm), and the height of the limiting block is adjustable (30-80mm). Positioning can be quickly adjusted according to the size of the pearl cotton material (e.g., 600×400mm, 800×500mm), adapting to the processing of different specifications of materials. The die-cutting tools can be replaced according to processing requirements, including the YH-300 flatbed die suitable for pearl cotton with a thickness ≤5mm and the YH-500 deep die suitable for pearl cotton with a thickness of 5-10mm. The tools are connected to the cylinder piston rod via quick-release clips, with a replacement time of ≤5 minutes, meeting the processing needs of pearl cotton of different thicknesses.

[0020] III. Convenient Operation and Reduced Labor Costs: The entire processing is fully automated through PLC control. From the movement of raw materials after loading, die-cutting to material discharge, minimal manual intervention is required, reducing manual operation steps, lowering labor intensity, and saving labor costs. The material discharge auxiliary mechanism facilitates the cleaning of residual impurities after die-cutting. The sliding ring slides along the horizontal track, with an adjustable range covering the entire material discharge section. The horizontal bar slides along the vertical track, with an adjustable height (0-150mm) to accommodate different thicknesses of pearl cotton. When not in use, the hanging ring can be suspended on the hanging rod, making operation flexible and convenient, improving processing cleanliness without affecting other processes.

[0021] IV. Improved processing efficiency and continuous batch production: All components work collaboratively, with a single cycle time controllable within 5-15 seconds (adjusted according to raw material size and die-cutting complexity). This enables continuous batch production, significantly improving efficiency compared to traditional intermittent processing methods, making it suitable for large-scale production needs. The processing platform has a processing section and a discharge section on either side of the notch. The die-cutting support platform moves back and forth between these sections, driven by the moving support components. Material is loaded in the processing section and unloaded in the discharge section. Die-cutting is completed as the material passes through the support frame, ensuring smooth workflow and reducing waiting time between processes. Attached Figure Description

[0037] In this embodiment, the cylinder 11 is used in conjunction with the servo motor 214, and the PLC controls it.

[0038] In this embodiment, a material discharge auxiliary mechanism is provided on the processing platform 2 and above the material discharge section. The material discharge auxiliary mechanism 3 includes a horizontal track 30, a sliding ring 31, a vertical track 32, a crossbar 33, a brush plate 34, a hanging ring 35, and a hanging rod 36. The horizontal track 30 is provided on both sides of the processing platform 2 and has a rectangular cross-section. The sliding ring 31 is slidably provided on the horizontal track 30, and the vertical track 32 is provided on the sliding ring 31. The crossbar 33 has through holes at both ends and is slidably provided on the vertical track 32. The brush plate 34 is provided on the bottom surface of the crossbar 33, the hanging ring 35 is fixedly provided on the top surface of the crossbar 33, and the hanging rod 36 is provided on the bracket 10. The hanging ring 35 can be suspended on the hanging rod 36.

[0039] The die-cutting unit is the core processing unit of the equipment. It mainly consists of a support frame 10, which is welded from Q235 steel plate with dimensions of 2500×1200×1800mm, a cylinder 11, a die-cutting cutter, and a guide structure.

[0040] Cylinder 11 is a standard SC125×500 cylinder with a stroke of 500mm and a working pressure of 0.4-0.8MPa. It is fixed upside down on the top of bracket 10. The piston rod is detachably connected to the die-cutting tool through a flange, which can drive the tool to achieve vertical creasing and die-cutting action.

[0041] The guide structure consists of a mounting base 12 (cast iron, 50mm thick) and a guide slide rod 13 (45 steel, 30mm in diameter, 600mm in length). The mounting base 12 is symmetrically welded to both sides of the bracket 10. The guide slide rod 13 slides through the sliding hole of the mounting base 12 and is fixed at the bottom end to the top of the die-cutting tool with a bolt to ensure the stability of the tool's up and down movement.

[0042] The die-cutting cutters are replaceable according to processing requirements. Commonly used models include the YH-300 flat die (suitable for pearl cotton with a thickness of ≤5mm) and the YH-500 deep die (suitable for pearl cotton with a thickness of 5-10mm). The cutters are connected to the piston rod of cylinder 11 via quick-release clips, and the replacement time is ≤5 minutes.

[0043] The processing platform is an integral cast iron structure (3000×1500×800mm). A rectangular notch 20 (2000×800×100mm) is opened in the middle of the top. A movable support component 21 and a die-cutting carrier 22 are installed inside the notch 20. The processing section (near the loading end) and the discharge section (near the unloading end) are located on both sides of the notch 20.

[0044] The die-cutting support table 22 is a horizontal steel plate 23 (20mm thick, 1800×700mm in size). Multiple sets of locking blocks 24 are distributed in a matrix on the top, and the spacing between the locking blocks 24 is adjustable (range 50-300mm). Each set of locking blocks includes a base block 25 (nylon material, 50×50×20mm) and a limiting block 26 (rubber material, height adjustable 30-80mm). The base block 25 is slidably connected to the horizontal steel plate through a T-slot, and the limiting block 26 is fixed to the base block 25 with bolts. The positioning can be quickly adjusted according to the size of the pearl cotton raw material (such as 600×400mm, 800×500mm).

[0045] The movable support assembly 21 is used to drive the die-cutting support table 22 to move horizontally back and forth between the processing section and the unloading section. It includes: a screw 210 (trapezoidal thread, 40mm diameter, 8mm pitch, 2000mm length): both ends are rotatably mounted in the notch 20 via bearing seats (model UCP208), made of 40Cr heat-treated material. Two horizontal slide bars 211 (2 bars, 25mm diameter, 2000mm length): fixed parallel to the screw 210 on both sides of the notch 20, made of chrome-plated round steel to reduce sliding friction. An internal thread seat 212 and a horizontal slide block 213 are welded to the bottom surface of the horizontal steel plate 23. The internal thread seat 212 is threadedly engaged with the screw 210, and the sliding hole of the horizontal slide block 213 is clearance-fitted with the horizontal slide bar 211 (clearance 0.05-0.1mm) to ensure the straightness of the support table movement is ≤0.5mm / m.

[0046] The power system adopts a servo drive + mechanical transmission structure to achieve precise movement of the platform: the servo motor 214 is a Mitsubishi HG-KR73BJ (750W power, rated speed 3000rpm, positioning accuracy ±0.01mm), connected to the input shaft of the right-angle transmission gearbox 215 (model T2-1:1) via a flexible coupling. The right-angle transmission gearbox 215 is connected to one end of the screw 210 via a coupling, and the connecting shaft 216 (diameter 25mm) is supported on the bottom surface of the processing platform 2 via bearing housing 217 (model UCP205) to ensure stable power transmission. The system is controlled by a PLC (Siemens S7-1200CPU1214C), which can preset the moving speed (0-500mm / s adjustable) and dwell time (0-10s adjustable), and is linked with the cylinder 11 to achieve fully automatic processing.

[0047] The material discharge auxiliary mechanism is used to clean residual impurities after die-cutting and improve the cleanliness of the process. The mechanism includes a horizontal track 30 (aluminum alloy, 30×30mm cross-section) fixed to both sides of the processing platform 2. A sliding ring 31 (nylon material) slides along the horizontal track 30, with an adjustment range covering the entire discharge section. A vertical track 32 (same specifications as the horizontal track) is vertically fixed to the sliding ring 31. A crossbar 33 (stainless steel, 800mm long) slides along the vertical track 32 through a through hole, adjusting its height (0-150mm) to accommodate different thicknesses of pearl cotton. A brush plate 34 (with nylon brushes embedded at the bottom, 700mm long) is bolted to the bottom of the crossbar 33, effectively cleaning debris without damaging the pearl cotton surface. A hanging ring 35 (stainless steel material) is welded to the top of the crossbar 33 and can be suspended on the hanging rod 36 of the bracket 10 when not in use, avoiding interference with other processes.

[0048] Working principle 1. Feeding stage: Place the pearl cotton raw material between the clamping blocks 24 of the die-cutting support table 22. By adjusting the position of the bottom block 25 and the height of the limiting block 26, ensure that the raw material is firmly positioned (offset ≤ 1mm).

[0049] 2. Moving stage: The PLC controls the servo motor 214 to start, which drives the screw 210 to rotate through the right-angle transmission gearbox 215. The internal thread seat 212 drives the horizontal steel plate 23 to move along the horizontal slide bar 211 to the processing section. The moving speed is set according to the thickness of the raw material (300-500mm / s for thin materials, 100-300mm / s for thick materials).

[0050] 3. Die-cutting stage: When the die-cutting support platform 22 reaches the processing section (directly below the die-cutting tool), the PLC sends a signal to stop the servo motor 214. At the same time, the cylinder 11 is vented, and the piston rod drives the die-cutting tool to move downward along the guide slide 13 to perform creasing die-cutting on the pearl cotton (the pressure is set by the pressure regulating valve, with a range of 0.3-0.6MPa, using the smaller value for thin materials and the larger value for thick materials). After holding the pressure for 0.5-2s, the cylinder resets.

[0051] 4. Material Removal Stage: After die-cutting, the servo motor 214 reverses, driving the die-cutting support table 22 to move to the material removal section. The sliding bar 33 of the material removal auxiliary mechanism causes the brush plate 34 to contact the surface of the die-cutting support table 22, moving along the horizontal track 30 to clean residual impurities, ensuring a clean table surface for the next processing. Material removal is also achieved manually. 5. Cyclic Processing: Repeat the above steps to achieve continuous batch production. The single cycle time can be controlled within 5-15 seconds (adjusted according to the raw material size and die-cutting complexity).

[0052] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0053] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
