[0022] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0023] like Figures 1 to 4 As shown, the nonwoven garment overall cutting device of the present invention includes a robust mounting frame 1 and an electrical box 10 for controlling the operation of the entire device. Along the transport path of the fabric (i.e., the folded nonwoven fabric), the mounting frame 1 is sequentially provided with: a plurality of fabric guide rollers 13 for guiding and flattening the fabric, a first conveying roller 8, a first cutting assembly, a second conveying roller 9, and a second cutting assembly.

[0024] The first conveyor roller 8 and the second conveyor roller 9 are responsible for providing stable traction to ensure the tension and feed speed of the fabric during the cutting process.

[0025] The first cutting assembly specifically includes a first cutting motor 7, a first anvil roller 6, a cutting roller 5, and a first transmission gear set. The first cutting motor 7 is fixedly mounted on the mounting frame 1. The first anvil roller 6 and the cutting roller 5 are arranged in parallel and rotatably connected to the mounting frame 1 through bearings and other components. The first anvil roller 6 and the cutting roller 5 achieve precise meshing transmission through the first transmission gear set, ensuring that their linear speeds are synchronized. One end of the first anvil roller 6 is connected to the output end of the first cutting motor 7 through a coupling or reduction mechanism, thereby being driven to rotate by the first cutting motor 7. A cutting blade 51 is mounted on the side of the cutting roller 5. This cutting blade 51 can be a straight blade, mainly used for preliminary cutting or trimming of the fabric.

[0026] The second cutting assembly includes a second cutting motor 4, a second anvil roller 3, a shaped cutting roller 2, and a second transmission gear set. The second cutting motor 4 is fixedly mounted on the mounting frame 1. The second anvil roller 3 and the shaped cutting roller 2 are also arranged in parallel and rotatably connected to the mounting frame 1 via bearings. Precise meshing transmission is achieved between the second anvil roller 3 and the shaped cutting roller 2 through the second transmission gear set. One end of the second anvil roller 3 is connected to the output end of the second cutting motor 4 via a coupling or reduction mechanism, and is driven to rotate by the second cutting motor 4.

[0027] The surface of the irregular-shaped cutting roller 2 is provided with raised irregular-shaped cutting edges 21. The shape of the irregular-shaped cutting edges 21 is designed according to the outer contour of the final garment (such as an isolation gown), and the external dimensions are shown in the figure. Figure 5 As shown, the shape is mirror-symmetrical along the axis of the shaped cutting roller 2. When the folded fabric passes through the pressing area between the second anvil roller 3 and the shaped cutting roller 2, the rotating shaped cutting edge 21 cooperates with the second anvil roller 3 to cut the multi-layer nonwoven fabric into the specified, complete outer contour shape of the garment in one go.

[0028] To ensure cutting quality and service life, both the second anvil roller 3 and the irregular cutting roller 2 are made of high-strength alloy steel, and the irregular cutting edge 21 is heat-treated to improve hardness and wear resistance.

[0029] The mounting frame 1 is equipped with precisely machined upper and lower roller supports and a flat working base to support and position all roller shafts, including the first conveyor roller 8, the first anvil roller 6, the cutting roller 5, the second conveyor roller 9, the second anvil roller 3, and the shaped cutting roller 2. This structure ensures that the roller axes are parallel and the spacing is stable, providing a solid mechanical foundation for continuous and precise cutting.

[0030] Both the first and second cutting components are equipped with protective covers 12 on their tops to increase operational safety.

[0031] To optimize the equipment's operating environment and protect the transmission components, gearboxes 11 are configured for the first and second transmission gear sets, respectively. The gearboxes 11 are fixedly mounted on the mounting frame 1, completely enclosing the corresponding gear sets. The gearboxes 11 have excellent sealing properties, effectively preventing dust, fabric fibers, and other contaminants from entering the gear meshing area. They also collect and reduce lubricating oil splashes, lower operating noise, extend gear life, and make the equipment appear cleaner and safer.

[0032] Work process:

[0033] First, the multi-layered folded nonwoven fabric is guided through the fabric roller 13 and pulled into the first cutting assembly area by the first conveyor roller 8. Between the first anvil roller 6 and the cutting roller 5, the cutting blade 51 performs a preliminary cut on the fabric. Subsequently, the fabric, pulled by the second conveyor roller 9, enters the second cutting assembly area. The second anvil roller 3 and the shaped cutting roller 2 rotate synchronously in opposite directions under the drive of the second cutting motor 4. The high-speed moving shaped blade 21 presses against the second anvil roller 3, instantly completing the overall shape cutting of the designated welding area of ​​the fabric. The cut semi-finished fabric is then sent out for subsequent processes.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
