[0039] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0040] Embodiment 1

[0041] A non-woven fabric cutting device, such as Figures 1 to 4As shown, it comprises a rack 1, a tension roller 2, a conveying assembly 3, a cutting assembly 4 and a suction roller 5. The rack 1 is provided with wall plates 11 on both sides, and the tension roller 2, the conveying assembly 3 and the suction roller 5 are sequentially arranged between the wall plates 11 on both sides. The non-woven fabric 6 passes through the tension roller 2, the conveying assembly 3 and the suction roller 5 in sequence.

[0042] Figure 2 and Figure 3 As shown, the cutting assembly 4 comprises a first linear module 41 arranged along the moving direction of the non-woven fabric 6, a second linear module 42 arranged perpendicular to the moving direction of the non-woven fabric 6, a third linear module 43 moving up and down, and a cutting knife 44. The second linear module 42 is connected with the first linear module 41, the third linear module 43 is connected with the second linear module 42, and the cutting knife 44 is connected with the third linear module 43. Specifically, the inner wall of the wall plate 11 is provided with a mounting plate 12, and the first linear module 41 is arranged on the mounting plate 12. The first linear module 41 can adopt a device capable of realizing linear movement such as an electric sliding table. The first linear module 41 is connected with a first connecting plate 45, and the second linear module 42 is connected with the first linear module 41 through the first connecting plate 45. The second linear module 42 can also adopt a device such as an electric sliding table. The second linear module 42 is connected with a second connecting plate 46, and the third linear module 43 is arranged on the second connecting plate 46. The third linear module 43 can adopt a device capable of realizing up and down movement such as a pneumatic cylinder or an electric push rod.

[0043] Through the first linear module 41, the cutting knife 44 moves synchronously with the non-woven fabric 6 between the conveying assembly 3 and the suction roller 5, that is, the first linear module 41 can drive the cutting knife 44 to move along the moving direction of the non-woven fabric 6, so that the cutting knife 44 remains relatively stationary with the non-woven fabric 6, thereby avoiding cutting deviation. The suction roller 5 is used to pull the non-woven fabric 6 to be cut, so that the non-woven fabric 6 remains in a tensioned state, facilitating cutting. Through the second linear module 42, the cutting knife 44 moves along the width direction of the non-woven fabric 6 to cut the non-woven fabric 6, that is, the second linear module 42 can drive the cutting knife 44 to perform cutting work in the width direction of the non-woven fabric 6. At the same time, with the movement of the non-woven fabric 6, when the cutting position of the non-woven fabric 6 moves to the suction roller 5, the cutting is just completed. At this time, the non-woven fabric 6 does not separate due to the suction effect of the suction roller 5, so that the next cutting can be performed.

[0044] The non-woven fabric cutting device of the embodiment realizes accurate cutting of the cutting knife 44 during the movement of the non-woven fabric 6 by arranging the first linear module 41, the second linear module 42 and the third linear module 43, improves the cutting efficiency, and avoids cutting deviation.

[0045] Example 2

[0046] Figure 3 and Figure 4As shown, the embodiment optimizes the mounting structure of the cutting knife 44 based on the embodiment 1. Specifically, the third linear module 43 is provided with a sliding block 47, the sliding block 47 is connected with a third connecting plate 48 arranged in the up-down direction, and the cutting knife 44 is detachably connected to the third connecting plate 48. In this way, the mounting and dismounting of the cutting knife 44 are facilitated, and the cutting knife 44 is convenient to replace or maintain.

[0047] Further, the third connecting plate 48 is provided with a sliding groove 49 in the up-down direction, and the cutting knife 44 is provided with a mounting hole. The mounting of the cutting knife 44 is realized by the bolt passing through the mounting hole and the sliding groove 49. Through the sliding groove 49, the mounting position of the cutting knife 44 on the third connecting plate 48 can be adjusted, so that the height of the cutting knife 44 can be adjusted according to actual needs, further improving the flexibility and accuracy of cutting.

[0048] Embodiment 3

[0049] Figure 4 As shown, the embodiment optimizes the cutting edge of the cutting knife 44 based on the embodiment 2. Specifically, the lower end of the cutting knife 44 is provided with an oblique cutting edge 441, and the oblique cutting edge 441 cuts the non-woven fabric 6 along the width direction of the non-woven fabric 6 through the movement of the cutting knife 44. The setting of the oblique cutting edge 441 can improve the cutting efficiency and make the cutting surface more flat.

[0050] Further, the oblique cutting edge 441 is provided with two, and the two oblique cutting edges 441 are symmetrically arranged below the cutting knife 44. In this way, after completing the cutting once, only the movement of the first linear module 41 is needed, thereby improving the cutting efficiency, making the cutting surface more uniform, and improving the cutting quality.

[0051] In summary, the non-woven fabric cutting device of the utility model realizes the accurate cutting of the cutting knife in the movement process of the non-woven fabric, improves the cutting efficiency, and avoids the cutting deviation by setting the first linear module, the second linear module and the third linear module. At the same time, the mounting structure and the cutting edge of the cutting knife are optimized, further improving the flexibility and accuracy of cutting, and the cutting quality and efficiency.
