[0036] like Figure 1 As shown, an embodiment of the present invention provides a non-woven fabric cutting device, including a base 1, wherein guide parts 2 are symmetrically arranged at both ends of the upper end surface of the base 1, and the guide parts 2 are two symmetrically arranged mounting ear structures, and a guide roller 201 is rotatably installed between the two mounting ears, and the upper end surface of the guide roller 201 is not lower than the upper end surface of the base 1.

[0037] like Figure 2 As shown, a fixed frame 3 is fixed to the middle part of the upper end of the base 1, and a cylinder 4 is fixed to the middle part of the upper end surface of the fixed frame 3. The axis of the cylinder 4 vertically passes through the top lower end surface of the fixed frame 3 and is fixed with a cloth cutting mechanism 5. The cloth cutting mechanism 5 includes a movable frame 501, and two movable blocks 6 are symmetrically slidably provided on the lower end surface of the movable frame 501, and a cutting wheel 7 is rotatably installed on the bottom of the movable block 6.

[0038] Specific cooperation Figure 3As shown, a horizontal lead screw 502 is rotatably installed on the lower end surface of the movable frame 501, and two opposite threaded sections are symmetrically constructed on the lead screw 502, which respectively pass through the middle of the two movable blocks 6, and the upper end surface of the movable block 6 slides against the lower end surface of the movable frame 501. A screw hole 601 is provided on the top of the movable block 6 for the lead screw 502 to pass horizontally, so that when the lead screw 502 rotates, the two movable blocks 6 can be driven to slide on the lower end surface of the movable frame 501, thereby driving the two cutting wheels 7 to move in a mirrored manner, thereby achieving the effect of quickly adjusting the distance between the two cutting wheels 7.

[0039] In addition, one end of the movable frame 501 extends out of the side of the movable frame 501 and is fixed with a screw cap 503. A vertical strip-shaped through-slot is opened on one side of the fixed frame 3, and the screw cap 503 passes through the strip-shaped through-slot. Therefore, it is convenient to rotate the screw 502 by screwing the screw cap 503.

[0040] Cooperate Figure 4 As shown, two symmetrically arranged mounting frames 504 are elastically mounted on both sides of the bottom of the movable frame 501 , and a tensioning roller 8 is rotatably mounted between the two symmetrically arranged mounting frames 504 . The horizontal position of the tensioning roller 8 is lower than that of the cutting wheel 7 .

[0041] In specific implementation, in this embodiment, a movable rod 505 tilted outward is inserted at one end of the mounting frame 504 away from the movable frame 501, and a fixed block 506 is fixed at the lower end of the movable rod 505. A spring 507 is sleeved on the movable rod 505, and the top end of the spring 507 is fixed on the mounting frame 504. The bottom end of the spring 507 is connected to the fixed block 506. The spring 507 elastically abuts the fixed block 506 downward, and the end of the tensioning roller 8 is rotatably installed on the side of the fixed block 506.

[0042] The working principle of the technical solution provided by the utility model is as follows:

[0043] When using the non-woven fabric cutting device, the screw 502 can be rotated by screwing the cap 503, so that the movable block 6 can move in a mirror image under the limit of the lower end surface of the movable frame 501, and then the distance between the two cutting wheels 7 can be adjusted to adapt to non-woven fabrics of different widths for cutting operations, which is easy to use.

[0044] At the same time, since tensioning rollers 8 are elastically installed on both sides of the bottom of the movable frame 501, when placing the cloth, the two tensioning rollers 8 are elastically abutted outward, so that before the movable frame 501 descends and drives the cutting wheel 7 to cut the edges, the two tensioning rollers 8 will first elastically abut and tension the cloth outward, thereby avoiding wrinkles in the cloth and ensuring the cutting effect of the non-woven fabric.

[0045] In summary, this device is not only flexible to use and can quickly and easily adjust the spacing between the two cutting wheels 7 to adapt to non-woven fabrics of different widths for cutting edges, but it can also automatically elastically tension the non-woven fabrics to avoid wrinkles and ensure the cutting effect, with good overall use effect.

[0046] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
