[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0036] See also Figure 1 - Figure 4 A trimming device for non-woven fabric processing includes a frame 1 and a feed roller 2, a cutting roller 3, a tensioning roller 4, a winding roller 5, a trimming mechanism, and a waste material guiding mechanism arranged in the frame 1. The feed roller 2 is arranged at the front end of the frame 1 and is used to transport the non-woven fabric raw material. The cutting roller 3 is installed on the rear side of the feed roller 2 and is used for preliminary positioning and auxiliary transportation of the non-woven fabric. The tensioning roller 4 is arranged above the cutting roller 3 to ensure that the non-woven fabric maintains appropriate tension during the cutting process to improve the cutting accuracy. The winding roller 5 is located on the rear side of the tensioning roller 4 and is responsible for winding up the non-woven fabric product that has completed trimming.

[0037] The nonwoven fabric passes sequentially through the feed roller 2, cutting roller 3, and tensioning roller 4 before being wound up on the wind-up roller 5, forming a complete production line. The trimming mechanism is located behind the cutting roller 3. Its primary function is to cut the nonwoven fabric edges wound around the cutting roller 3. The waste guide follows the trimming mechanism. After the nonwoven fabric edges are cut on the cutting roller 3, they pass through the tensioning roller 4 and enter the waste guide for processing.

[0038] Furthermore, Figure 3 and Figure 4 As shown, the trimming mechanism includes a slitter mounting post 6 and a pneumatic slitter 7. The slitter mounting post 6 is securely mounted on the rear side of the cutting roller 3, while the pneumatic slitter 7 is mounted on the slitter mounting post 6. Specifically, two pneumatic slitter blades 7 are provided, one at each end of the slitter mounting post 6. This design ensures that both sides of the nonwoven fabric are cut simultaneously, improving work efficiency.

[0039] The pneumatic slitting knife 7 is also designed with a snap-in slot 8 and a fastening screw 9. The snap-in slot 8 allows the pneumatic slitting knife 7 to be flexibly adjusted on the slitting knife mounting post 6, while the fastening screw 9 is used to firmly fix the pneumatic slitting knife 7 on the slitting knife mounting post 6 to ensure the stability of the cutting process.

[0040] The waste material guide mechanism consists of a driving rubber shaft 10 and a passive rubber shaft 11. Both are mounted on the machine frame and located behind the trimming mechanism. The driving and passive rubber shafts 10, 11 are tightly abutted against each other, forming a clamping channel. A first motor 12 is also mounted on the machine frame 1 and is in transmission connection with the driving rubber shaft 10, driving its rotation. After cutting, the nonwoven fabric scraps are fed into this clamping channel. The coordinated rotation of the driving and passive rubber shafts 10, 11, allows the scraps to be smoothly discharged.

[0041] In addition, a waste collection frame 13 is also configured in the frame 1. It is located below the waste guide mechanism and is used to collect the nonwoven fabric trimmings that are exported. Casters 14 are housed at the bottom of the waste collection frame 13 for ease of movement and cleaning.

[0042] Finally, a winding roller support drive mechanism is installed on both sides of the top of the frame 1. Each winding roller support drive mechanism includes a first support wheel 15, a second support wheel 16, and a second motor 17. The first and second support wheels 15, 16 are spaced apart and jointly support the winding roller 5. The second motor 17 is in driving connection with the first support wheel 15 or the second support wheel 16. By driving the rotation of the support wheel, the winding roller 5 is rotated, thus achieving the winding operation of the nonwoven fabric.

[0043] In summary, the edge trimming device for non-woven fabric processing of the present invention realizes efficient cutting and automatic exporting of non-woven fabric edge materials through reasonable structural design, greatly improves production efficiency, and reduces the burden of manual operation.

[0044] Obviously, the embodiments described are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art are within the scope of protection of the present invention.
