As shown in fig. 11, the present embodiment has substantially the same structure as that of embodiment 2, except that a third needle bed 26 is disposed below the pad 11, a knitting needle 22 of the third needle bed 26 is disposed perpendicular to the plane of the pad 11, and a first cylinder 23 and a second cylinder 25 are fixedly mounted on both sides of the third needle bed 26. That is, in the present embodiment, the small-sized electromagnet device 24 and the first needle bed 2 provided on the second needle bed 21 side and corresponding to the needle slot of the second needle bed 21 are eliminated, as compared with embodiment 2.

The working principle of the embodiment is that initial preparation: warp yarn 91 passes through a knitting needle 22 and is introduced into a yarn guide plate, a non-woven fabric is placed between the plane of a backing plate 11 and a yarn hooking device 315, one side of the non-woven fabric is connected with a large roller and a small roller, the weft yarn on the upper layer passes through a yarn guide 411 below a fifth cylinder 41 and passes through a cutter support 421 below a sixth cylinder 42 and is clamped by a wire puller 432 of a seventh cylinder 43, and the weft yarn on the lower layer passes through a second yarn guide 614 on an eighth cylinder 61 and is fixed on one side.

During the movement process, the knitting needle 22 moves upwards under the action of the first air cylinder 21 and the second air cylinder 25, after the knitting needle penetrates through a fiber mesh layer and reaches the top stroke of the air cylinders, the thread hooking device 315 hooks warps on the knitting needle 22 out of holes with certain width under the drive of the third air cylinder 31 through the first push rod 313 and the first connecting rod 312, the fourth air cylinder 32 drives the long-handle thread clamping device 323 to pass through the holes, after the knitting needle reaches the stroke of the fourth air cylinder 32 (at the moment, the head of the long-handle thread clamping device 323 is between the fifth air cylinder 41 and the sixth air cylinder 42), the fifth air cylinder 41 drives the first thread guide 411 to move upwards, upper wefts are clamped in the process of the retraction of the long-handle thread clamping device 323, when the long-handle thread clamping device 323 retracts, the seventh air cylinder 43 drives the thread puller 432 to advance, the fifth air cylinder 41 sinks to act on the first thread guide device to move downwards again, so that the upper wefts are hooked and retracted by the thread guide 432 and clamped, after the fourth air cylinder 32 drives the long-handle thread clamping device 323 to pull the upper wefts out of a cushion plate 11 interface of the slotted hole, the sixth cylinder 42 drives the cutter 422 to cut off the upper weft, the long-handle thread clamp 323 continues to retreat to contact with the stop block 321 on the second bracket 3, the stop block 321 acts on a spring to release the thread pressing sheet 324 to release the upper weft, the third cylinder 31 drives the first connecting rod 312 and the first push rod 313 to move to return the thread hooking device 315 to an initial position, the knitting needle 22 moves downwards under the action of the first cylinder 21 and the second cylinder 25 again, after the bottom stroke of the cylinder is reached, the eighth cylinder 61 drives the second thread guide 614 to guide the lower weft to the other side of the base plate 11 from one side of the base plate 11 at the joint of the warp and the fiber mesh layer, and the driving motor 51 drives the large roller 52 to move to enable the fiber mesh layer to move forwards by a distance integrally, so that one period of control motion is completed.

Example 4

As shown in fig. 12, this embodiment discloses a method for manufacturing yarns embedded in a fiber web, in which a control system controls the small electromagnet device 24 to electrically attract the corresponding knitting needle 22, so that the small electromagnet device drives the parallel arranged warp yarns 61 to penetrate through the embedded yarn fiber web layer 9, the thread hooking device 315 moves on the upper layer of the embedded yarn fiber web layer 9 to make the warp yarns 91 attached to the knitting needle 22 form loops 94, the upper layer weft yarns 92 are introduced in the direction perpendicular to the parallel warp yarns 91, after the upper layer weft yarns 92 are introduced into the loops 94, the thread hooking device 315 returns to the original position, the knitting needle 22 moves down, the thread guide 10 pads the lower layer weft yarns 93 at the boundary of the warp yarns 91 and the embedded yarn fiber web layer 9, and the lower layer weft yarns 93 are fixed when the knitting needle 22 moves up again.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the technical solutions of the embodiments of the present invention.
