Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 2The utility model provides an embodiment: a positioning device for cutting non-woven fabrics, including a base 1, the base 1 can support the entire device, the right part of the base 1 is rotatably connected to a support shaft 6, the support shaft 6 can support the rolled non-woven fabric so that it can be horizontally rotated and spread out for cutting, the upper part of the base 1 is fixedly connected to a fixed column 2, the fixed column 2 can support a sliding block 13 so that it can only slide vertically, the upper end of the fixed column 2 is slidably connected to a sliding block 13, the sliding block 13 is L-shaped, and can drive the positioning shaft 5 to slide vertically, the front part of the sliding block 13 is fixedly connected to a positioning shaft 5, the positioning shaft 5 is U-shaped, and can support the positioning component, and both ends of the positioning shaft 5 are threadedly connected with The positioning component includes a rotating disk 3, which can conveniently drive the threaded rod 7 to rotate, so as to facilitate the extrusion of non-woven fabrics of different thicknesses and clamping forces. The lower part of the rotating disk 3 is fixedly connected with a threaded rod 7, and the rotation of the threaded rod 7 can adjust the height of the extrusion shaft 9 and the clamping force on the non-woven fabric. The lower part of the threaded rod 7 is rotatably connected with a fixed groove 8, and the fixed groove 8 limits the internal extrusion shaft 9 to horizontal rotation. The lower end of the fixed groove 8 is internally rotatably connected with the extrusion shaft 9, and the extrusion shaft 9 can cooperate with the base 1 to clamp the non-woven fabric and prevent it from sliding. The external threads of the threaded rod 7 are connected to the inside of the two ends of the positioning shaft 5, and the positioning shaft 5 limits the threaded rod 7 to rotation and vertical sliding.

[0033] Reference Figure 1 , Figure 4 and Figure 5 The interior of the positioning shaft 5 is elastically connected with a card block 14 through a spring 15. The card block 14 is Y-shaped. A square groove is provided at the upper end of the fixed column 2 to clamp the upper and lower ends of the card block 14 to fix it. The outside of the card block 14 is slidably connected to the inside of the card block 14 and the fixed column 2 respectively. By sliding the card block 14 to push it out of the square groove and then sliding up so that the lower part of the card block 14 slides into the upper square groove, the extrusion shaft 9 can slide up quickly for convenient loading. One end of the spring 15 is fixedly connected to the interior of the positioning shaft 5, and the other end of the spring 15 is fixedly connected to the left part of the card block 14. The spring 15 is squeezed to keep the card block 14 in the square groove. The upper end of the positioning shaft 5 is slidably connected with a connecting rod 12, and the lower parts of the two ends of the connecting rod 12 are slidably connected to the upper end of the positioning shaft 5. The connecting rod 12 is limited by the positioning shaft 5 to only slide vertically, and can drive the inclined plane blocks 16 at both ends to slide up and down at the same time. The lower part of the connecting rod 12 is fixedly connected with the inclined plane block 16, and the inclined plane block 16 can squeeze the block 14 to slide into the positioning shaft 5. The outside of the inclined plane block 16 is respectively slidably connected to the inside of the two ends of the positioning shaft 5 and the left end of the block 14. The inclined plane block 16 is limited to only slide relatively vertically within a fixed distance, and a release assembly is fixedly connected in the middle of the lower end of the positioning shaft 5.

[0034] Reference Figure 1 and Figure 3The release assembly includes a U-shaped rod 4, which can support and limit the relative vertical sliding of the release rod 10 within a fixed distance. The lower parts of the two ends of the U-shaped rod 4 are fixedly connected to the middle of the positioning shaft 5. The positioning shaft 5 can drive the U-shaped rod 4 to slide up and down at the same time. The two ends of the U-shaped rod 4 are internally slidably connected with the release rod 10. The release rod 10 can drive the connecting rods 12 at both ends to slide simultaneously for easy release. The lower parts of the two ends of the release rod 10 are fixedly connected with the extrusion blocks 11. The downward movement of the extrusion blocks 11 can drive the connecting rod 12 to slide down, and the lower part of the extrusion block 11 is in contact with the upper part of the connecting rod 12.

[0035] Working principle: By rotating the rotating disk 3, the threaded rod 7 can be driven to rotate. The rotation of the threaded rod 7 can slide down under the extrusion of the positioning shaft 5. The sliding of the threaded rod 7 drives the fixed groove 8 to slide down. The sliding of the fixed groove 8 can drive the extrusion shaft 9 to slide down until it contacts and clamps the non-woven fabric. When the non-woven fabric on the upper end of the support shaft 6 is cut, the new non-woven fabric is placed in the middle of the support shaft 6, and then the release rod 10 is squeezed. The release rod 10 drives the extrusion blocks 11 at both ends to slide down. The extrusion blocks 11 drive the connecting rods 12 at both ends to slide down. The connecting rod 12 slides down and drives the inclined block 16 to slide downward at the same time. The inclined block 16 squeezes the block 14 to slide into the inside of the sliding block 13 to release the limit, and then slides up the U-shaped rod 4, and the U-shaped rod 4 drives the positioning shafts 5 at both ends to slide up , the positioning shaft 5 drives the positioning assembly to slide upward at the same time, and releases the release rod 10. When it slides to a predetermined height, the spring 15 squeezes the lower part of the block 14 to slide into the interior of the fixed column 2, and the inclined block 16 drives the connecting rod 12 to slide up, so that the extrusion block 11 and the release rod 10 slide up. After the non-woven fabric is laid to the predetermined position, the release rod 10 is squeezed again to drive the extrusion block 11 to slide down. The connecting rod 12 drives the inclined block 16 to slide down under the extrusion of the extrusion block 11. The block 14 is squeezed and slides into the interior of the sliding block 13 to squeeze the spring 15, and then the U-shaped rod 4 slides down to drive the positioning shaft 5 and the positioning assembly to slide down to the original position. At this time, the spring 15 squeezes the block 14 to slide into the square groove and keep it fixed. At this time, the extrusion shaft 9 clamps the non-woven fabric for positioning.
