[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A nonwoven fabric production and cutting device, comprising:

[0026] Cutting table 1, with an arc-shaped groove 2 adapted to the shape of the non-woven fabric roll;

[0027] A cutting mechanism is mounted on a cutting table 1. The cutting mechanism includes a cutting seat 3 and a blade 7. The cutting seat 3 is mounted on the cutting table 1 and has a circular hole 9 that matches the arc-shaped groove 2 for the non-woven fabric roll to pass through. A cavity 8 is formed inside the cutting seat 3, connecting the cutting seat 3 and the circular hole 9. The blade 7 is slidably mounted inside the cavity 8. A hydraulic cylinder 5 for driving the blade 7 is mounted on the top of the cutting seat 3. A top plate 4 is mounted on the top of the cutting seat 3 by fixing screws. The hydraulic cylinder 5 is mounted at the top center of the top plate 4. The lower end of the hydraulic rod of the hydraulic cylinder 5 passes through the top plate 4 and is connected to a connecting plate 6. The connecting plate 6 is connected to the top of the blade 7 by fixing screws.

[0028] The cutting table 1 has a cutting groove 12 that is compatible with the blade 7.

[0029] The blade 7 has an inclined design at the bottom, with one side higher and the other side lower.

[0030] The arc-shaped groove 2 of the cutting table 1 provides a bonding support for the roll of nonwoven fabric. The round hole 9 of the cutting seat 3 is aligned with the arc-shaped groove 2 to form a through channel for the roll of material to pass through. The hydraulic cylinder 5 drives the hydraulic rod to extend and retract, and drives the blade 7 to move vertically along the cavity 8 through the connecting plate 6. The lower end of the blade 7 cooperates with the cutting groove 12 of the cutting table 1 to complete the cutting. The inclined design of the blade 7 allows the cutting contact point to gradually cut in from one side to the other, dispersing the cutting force.

[0031] It enables direct radial cutting of rolled nonwoven fabric without pre-unrolling. The matching structure of the arc groove 2 and the round hole 9 ensures stable positioning of the roll material. The tilted blade 7 reduces the impact force at the moment of cutting, avoiding deformation of the roll material or tearing of the cut. The cutting efficiency is improved compared with traditional unrolling cutting.

[0032] The inclined design of blade 7 ensures that during the cutting process, the higher side contacts the non-woven fabric first and then gradually cuts downwards, forming an oblique cutting force. This design reduces resistance during cutting, making the cutting easier and smoother, while also helping to improve the quality of the cut edge and reduce defects such as burrs.

[0033] Hydraulic cylinder 5 includes a power system:

[0034] Hydraulic pump station: It adopts a gear pump (displacement 10mL / r, rated pressure 16MPa) to supply oil, and is driven by a three-phase asynchronous motor (power 3kW, speed 1450rpm); the oil tank has a capacity of 40L and a built-in air-cooled cooler (temperature control range 35-55℃) to ensure that the system can work continuously for 8 hours without overheating.

[0035] Control circuit: A three-position four-way solenoid directional valve (center position functional type O) is used to control the hydraulic cylinder 5 to move forward and backward, and a speed regulating valve is used to achieve precise flow regulation (flow range 5-20L / min); the system pressure is set by a pilot-operated relief valve (working pressure 8-12MPa adjustable), and the equipment is automatically unloaded to protect it in case of overload.

[0036] Displacement control: Hydraulic cylinder 5 (63mm diameter, 100mm stroke) is equipped with a magnetostrictive displacement sensor (accuracy ±0.05mm) to provide real-time feedback on piston position.

[0037] For a preferred implementation, please refer to Figure 1-3 :

[0038] The inner walls on both sides of the cavity 8 are provided with guide grooves 11, and the outer walls on both sides of the upper end of the blade 7 are provided with guide blocks 10. The two sets of guide blocks 10 and the two sets of guide grooves 11 correspond to each other and slide together.

[0039] When the blade 7 slides up and down under the drive of the hydraulic cylinder 5, the guide block 10 slides in the guide groove 11. The guide groove 11 restricts the movement direction of the guide block 10, providing precise guidance for the sliding of the blade 7, preventing the blade 7 from deviating during the sliding process, ensuring that the blade 7 always cuts the non-woven fabric in the correct direction, and improving the accuracy and stability of the cutting.

[0040] For a preferred implementation, please refer to Figure 1-4 :

[0041] Both sides of the cutting seat 3 are provided with protruding plates 13 above the round holes 9. A cylinder 14 is installed on the protruding plate 13. The piston rod of the cylinder 14 passes through the protruding plate 13 and is connected to a pressure block 15. The bottom surface of the pressure block 15 is set in an arc shape that matches the arc groove 2, so as to press the two sides of the blade during cutting.

[0042] Among them, the top of the pressure block 15 is symmetrically provided with connecting rods, which are slidably inserted into the protrusion plate 13 for guidance.

[0043] When the blade 7 is ready to cut the nonwoven fabric, the cylinder 14 operates, and its piston rod extends to push the pressure block 15 downward. Since the bottom surface of the pressure block 15 is arc-shaped and matches the arc groove 2, it can closely fit the surface of the nonwoven fabric roll and press the nonwoven fabric on both sides of the blade. This prevents the nonwoven fabric from moving or deforming due to the cutting force of the blade 7 during the cutting process, ensuring the accuracy and stability of the cutting and improving the cutting quality.

[0044] When the cylinder 14 drives the pressure block 15 to move up and down, the connecting rod slides inside the convex plate 13, and the convex plate 13 restricts the movement direction of the connecting rod; it provides guidance for the up and down movement of the pressure block 15, so that the pressure block 15 can press the non-woven fabric down smoothly and accurately, avoid the pressure block 15 from shaking or deviating during the movement, and further improve the pressing effect.

[0045] The power source for cylinder 14 is a compressed air system.

[0046] Components: Air compressor (discharge capacity ≥ 0.3m³) 3 / min, pressure 0.6-0.8MPa) + air tank (volume ≥60L) + pneumatic triplet (filter, pressure reducing valve, oil mist lubricator).

[0047] Working principle: The air compressor generates compressed air, which is then pressure-stabilized by the air tank and delivered to cylinder 14 through the air pipe; the pneumatic triplet filters impurities (filtration accuracy ≤5μm), regulates air pressure (working pressure adjustable from 0.4-0.6MPa) and provides lubrication to ensure smooth operation of cylinder 14.

[0048] For a preferred implementation, please refer to Figure 1-2 :

[0049] The cutting base 3 is installed on the cutting table 1 by fixing screws. The bottom of the cutting base 3 is symmetrically provided with fixing blocks 16, and fixing holes are opened on the base corresponding to the fixing blocks 16.

[0050] During installation, place the cutting base 3 in a suitable position on the cutting table 1, align the fixing holes on the fixing block 16 with the fixing holes on the base, and then fix the cutting base 3 to the cutting table 1 with fixing screws; the top plate 4 is installed on the top of the cutting base 3 with fixing screws, and the connecting plate 6 is installed on the top of the blade 7 with fixing screws, which facilitates the installation and disassembly of various parts of the equipment, and makes the assembly, maintenance and repair of the equipment convenient.

[0051] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
