A grass loom core comprising: the straw cutting machine comprises a frame 1, a straw pulling roller 2, a straw cutting mechanism 3 and a needle inserting transmission mechanism 4. The frame 1 serves as a support frame for mounting other components. The grass pulling roller 2 comprises: a rotating ring 21 and a plurality of clamping rods 22; the rotating ring 21 is rotatably arranged on the frame 1; a plurality of clamping bars 22 are evenly distributed around the circumference of the rotating ring 21, and the clamping bars 22 comprise: a movable rod 221 and a fixed rod 222; the fixing rod 222 is fixed on the rotating ring; the movable rod 221 is slidably arranged adjacent to the fixed rod 222 along the length direction of the fixed rod 222; a plurality of clamping grooves 223 are formed in the length direction of the movable rod 221 and the fixed rod 222; the intervals between adjacent clamp grooves 223 are equal. The grass silk dissection mechanism 3 includes: a cutter shaft 31 and a cutter 32; the cutter shaft 31 and the fixed rod 222 are arranged on the frame 1 in parallel, and the cutter shaft 31 is arranged at a position corresponding to the grass-drawing roller 2 for clamping the grass filaments; the cutter 32 is slidably disposed on the cutter shaft 31, and the cutter 32 extends into the grass pulling roller 2, when the cut grass is required to be cut into sections, the cutter 32 is controlled to slide along the cutter shaft 31, and then the cut grass can be cut. The puncture transmission mechanism 4 includes: a lifter and needle mounting rod 43; the needle mounting rod 43 is arranged in the grass pulling roller 2 in a lifting and sliding manner and is parallel to the fixing rod 222; the needle mounting rod 43 is provided with a plurality of needles 5 corresponding to the positions of the clamping grooves on the fixing rod 222; the lifter is in transmission connection with the needle inserting mounting rod 43 and is used for driving the needle inserting mounting rod 43 to lift.

In practical application, the grass-pulling roller 2 may be provided with a pusher at a position on the fixing ring 21 corresponding to the position where the movable rod 221 needs to be pushed, so as to push the movable rod 221 to slide. Considering that a plurality of pushers are required in this way, in order to further optimize the transmission structure, the grass roller 2 of the present embodiment is further provided with: two guide rings 23; the two guide rings 23 are symmetrically disposed at two ends of the fixing rod 222 in the length direction, and inner end surfaces of the guide rings 23 facing the fixing rod 222 are concave-convex ring surfaces. Both ends of the movable rod 221 are connected with rollers 24; the rollers 24 at both ends of the movable rod 221 slidably abut against the inner end surfaces of the two guide rings 23, respectively.

Specifically, referring to the perspective view of the guide ring shown in fig. 5, the grass can enter the clamping bar 22 from the top position of the rotating ring 21, that is, the fixed bar 222 at the top of the grass-pulling roller 2 is aligned with the clamping groove 223 on the movable bar 221; along with the rotation direction of the rotating ring 21, the inner end surfaces of the two guide rings 23 are concave-convex along the same direction, so that the movable rod 221 starts to slide along the concave-convex direction of the guide rings 23, the clamping rod 22 gradually clamps the grass, and the cutter 32 can perform a cutting process on the clamped grass; in the process that the clamped grass wires gradually rotate towards the position close to the lower portion of the pricking needle mounting rod 43, the inner end faces of the two guide rings 23 can gradually incline in the same direction in a concave-convex mode, so that the clamping rod 22 loosens the grass wires, the pricking needle mounting rod 43 is controlled to be pressed downwards at the same time, and the implantation process is completed. That is, the guide ring 23 can automatically correspond to the cutting process and the implanting process along with the rotation of the rotating ring 21 to clamp and loosen the grass filaments, thereby further simplifying the transmission structure of the grass weaving machine core.

In practical application, the control of the pressing down of the needle mounting rod 43 needs to make the time when the needle 5 contacts the grass silk consistent with the time when the grass silk is changed from clamping to loosening as much as possible; because if the time for the clamping rod 22 to loosen the grass is too early, the loosened grass can fall off; if the time for the clamping bar 22 to release the grass filaments is too late, the pressure for pressing the grass filaments by the pricking pin 5 is increased, and the pricking pin 5 is damaged. Meanwhile, in the way that the concave-convex structure on the inner end surface of the guide ring 23 pushes the movable rod 221 to slide, in order to avoid the situation that the movable rod 221 is impacted due to the over-shaking of the inclined surface of the concave-convex structure, the inclination of the concave-convex structure should not be set too high. That is, in this way, there is a process of clamping and releasing the grass by the clamping bar 22, and if the process is too short, there is a risk of the movable bar 221 striking, and if the process is too long, the time of pressing down the needle 5 is not consistent with the time of releasing the grass.

In the present embodiment, in order to make the time of pressing down the needle 5 and the time of releasing the grass string as consistent as possible, the guide ring 23 is provided with two sections of upper ring section 231 and lower ring section 232; the upper ring segment 231 is fixed on the frame 1; the lower ring segment 232 is movably disposed along the length direction of the movable rod 221.

At the same time when the pricking needle 5 is pressed down to contact with the grass filaments, the movable rod 221 can be pushed to slide by pushing the lower ring section 232, so that the clamping rod 22 is controlled to loosen the grass filaments, the temporal consistency of the movable rod and the clamping rod is controlled, and in the process that the lower ring section 232 is pushed, the rotating ring 21 stops rotating until the lower ring section 232 resets. For this purpose, a sensor may be correspondingly disposed on the lower ring segment 232, and the rotation is stopped when the motor controlling the rotation of the rotating ring 21 senses that the lower ring segment 232 is pushed to displace.

Further, in the present embodiment, in order to further ensure the consistency between the pressing time of the needle inserting mounting rod 43 and the grass releasing time, the lifter comprises: the lifting structure 41 and the curved bar transmission structure 42; the lifting structure 41 includes: a vertical rod 411 and a lifting block 412; the vertical rod 411 is fixedly arranged on the frame 1; the lifting block 412 is slidably disposed on the vertical rod 411, and the lifting block 412 is fixedly connected to the needle insertion mounting rod 43.

Specifically, when the lifting block 412 descends, the slider 422 moves down along the lifting block 412 and slides along the sliding groove 425. Because the lower extreme of curved bar 421 is to keeping away from 2 direction bending of grass-pulling roller for the upper end, and slider 422 only can remove and curved bar 421's lower extreme and axis of rotation 423 fixed connection along vertical direction, consequently along with slider 422 promotes spout 425 downwards, curved bar 421 can drive axis of rotation 423 and rotate, and then drives push rod 424 and rotate, realizes the promotion to lower ring segment 232.

In this embodiment, by disposing the sliding block 422 on the lifting block 412, the needle inserting mounting rod 43 can be pushed down and the movable rod 221 can be pushed to slide, so that the pushing time of the needle inserting 5 is consistent with the loosening time of the grass thread.
