[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0023] Refer to Figures 1-4 , a textile fabric cutting device, including a cutting box 1, a plurality of support legs 2 are fixedly connected to the bottom of the cutting box 1, a cylinder 3 is fixedly connected to the inner top of the cutting box 1. The working principle of the cylinder 3 is prior art and will not be elaborated in detail here. The output end of the cylinder 3 is fixedly connected with an output rod, and the end of the output rod is fixedly connected with a mounting plate 4. The mounting plate 4 is connected with a cutter 5 through a clamping mechanism. The clamping mechanism includes a connecting plate 13. The outer side wall of the connecting plate 13 is fixedly connected with the cutter 5. A receiving groove is provided on the connecting plate 13. The bottom of the receiving groove is fixedly connected with a first telescopic rod 14. One end of the first telescopic rod 14 away from the bottom of the receiving groove is fixedly connected with a bump 16. An installation opening adapted to the connecting plate 13 is provided on the mounting plate 4. The connecting plate 13 is located in the installation opening. A pressing opening adapted to the bump 16 is provided on the side wall of the mounting plate 4. The bump 16 is located in the pressing opening. By pressing the bump 16, the bump 16 can be made to leave the pressing opening, and thus the connecting plate 13 can be separated from the mounting plate 4;

[0024] A elastic spring 15 is sleeved on the outer side wall of the first telescopic rod 14. Both ends of the elastic spring 15 are fixedly connected to the inner bottom of the storage groove and the outer side wall of the convex block 16 respectively. A servo motor 6 is fixedly connected to the outer side wall of the cutting box 1. The output end of the servo motor 6 is fixedly connected with a threaded rod 7. The threaded rod 7 is connected with two symmetrically arranged L-shaped plates 8. A limiting groove 12 is opened at the inner bottom of the cutting box 1. The bottom of the L-shaped plate 8 is slidably connected to the inner side wall of the limiting groove 12. There is a threaded opening on the L-shaped plate 8, and an external thread is provided on the outer side wall of the threaded rod 7. Among them, the external threads on the threaded rod 7 are arranged in two opposite and symmetric sections. Thus, while the threaded rod 7 rotates, the two L-shaped plates 8 move towards the relative or opposite sides, and thus the distance between the two L-shaped plates 8 can be adjusted;

[0025] The inner side wall of the threaded opening is provided with an internal thread adapted to the external thread, and the inner side wall of the threaded opening is threadedly sleeved on the outer side wall of the threaded rod 7. The L-shaped plate 8 is connected with a pressing mechanism. The pressing mechanism includes a second telescopic rod 9 fixedly connected to the bottom of the L-shaped plate 8. The bottom of the second telescopic rod 9 is fixedly connected with a pressing plate 10. A buffer spring 11 is sleeved on the outer side wall of the second telescopic rod 9. Both ends of the buffer spring 11 are fixedly connected to the outer side wall of the L-shaped plate 8 and the top of the pressing plate 10 respectively. A cutting opening 17 is provided at the inner bottom of the cutting box 1, and a waste collection box 18 corresponding to the cutting opening 17 is provided at the bottom of the cutting box 1.

[0026] The specific working principle of the present utility model is as follows:

[0027] In the initial state, the distance between the two L-shaped plates 8 is adjusted according to the width of the fabric, so as to facilitate the cutting process of fabrics with different widths. The servo motor 6 is started. The working principle of the servo motor 6 is prior art and will not be elaborated in detail here. When the servo motor 6 works, the electric threaded rod 7 rotates. Through the cooperation of the threaded rod 7 and the threaded opening on the L-shaped plate 8, the position of the L-shaped plate 8 is adjusted, and thus fabrics with different widths can be fixed;

[0028] After the position of the L-shaped plate 8 is adjusted, through the combined use of the second telescopic rod 9, the pressing plate 10 and the buffer spring 11, both ends of the fabric are fixed, avoiding the phenomenon that the fabric is unstable during the cutting process and thus shifting, resulting in wrinkles in the cutting, and improving the quality of the produced fabric;

[0029] After both ends of the fabric are fixed, the air cylinder 3 is started. The air cylinder 3 works to drive the cutter 5 to move downward, and thus the fabric is cut. Among them, the waste thread ends of the material will enter the waste collection box 18 through the cutting opening 17 for recycling;

[0030] When it is necessary to replace the cutting tool 5 according to the cross-sectional area of the cutting, simply press the convex block 16 by hand. The convex block 16 moves under the action of the first telescopic rod 14, and then the connecting plate 13 is removed from the mounting plate 4, realizing the rapid replacement of the cutting tool 5, solving the problem of inconvenient replacement of the cutting tool 5 in the prior art, and improving the practicability of the device.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
