As shown in FIG. 5, to ensure that the lancet 301 can pass smoothly and without interference through the lancet channel 101 and the blind hole 601 as the position of the lancet channel 101 and the blind hole 601 change, the aperture of the blind hole 601 is set larger than the aperture of the lancet channel 101 so that when the lancet 301 is in the retraction stroke, the head of the lancet 301 still has a longer buffer time to completely dislodge from the blind hole 601 than calculated from the tangential linear velocity of rotation of the lancet platform.
The working process of the device of the embodiment is as follows: the fiber web is fed between the shell 1 and the needling platform 6 at high speed, the shell 1 rotates in the counterclockwise direction, the cam 401 rotates in the clockwise direction, the needling platform 6 rotates in the clockwise direction, along with the relative rotation of the shell 1 and the cam 401, one needle plate 3 on the inner wall surface of the shell 1 starts to be pressed by the outline of the cam 401, the needles 301 on the needle plate 3 are pressed down into the extending stroke to penetrate the fiber web, when the cam 401 contacts the needle plate 3 at the maximum radial position, the needles 301 on the needle plate 3 reach the maximum extending stroke position to penetrate the fiber web, simultaneously under the synchronous rotation of the needling platform 6, the heads of the needles 301 momentarily extend into the blind holes 601 on the surface of the needling platform 6, along with the continuous relative rotation of the shell 1 and the cam 401, the pressure on the needles 301 on the needle plate 3 is gradually reduced, under the elastic force of the spring in the reset component 5, the needles 301 on the needle plate 3 upwards enter the retracting stroke, until it is extracted from the web and retracted into the housing 1, back to the initial position of the needles 301, and the next needle plate 3 begins to repeat the above steps as the housing 1 and cam 401 are further rotated relative to each other. When the fiber web moves forward at a high speed, the pricking pins 301 which are pricked into the fiber web are driven by the shell 1 to move for a short time in the same direction, so that the surface of a finished product can be well prevented from being marked by the straight up-and-down pulling movement of the pricking pins when the surface layer of the fiber web retracts, the surface smoothness of the finished product is ensured, and the production efficiency of the finished product is improved.
Example 3:
the technical scheme of the needling device of the high-speed needling machine is the same as that of the embodiment 2, and the differences are as follows: as shown in fig. 6, the transmission component 4 includes a stroke limiting element 404 and a fixed shaft 405, the stroke limiting element 404 is fixedly connected to the fixed shaft 405, the fixed shaft 405 is fixedly connected to the frame, the driving component does not include the first motor 201, that is, the relative position of the stroke limiting element 404 and the frame 7 is fixed, and the stroke limiting element 404 does not need to perform a rotational motion.

Accordingly, the needle plate 3 and the needles 301 on the needle plate 3 form the same included angle with the inner wall surface of the housing 1 to ensure that the needles 301 pass through the needle channel 101 in an unimpeded reciprocating manner. Accordingly, the blind hole 601 on the needling platform 6 is also at the above-mentioned angle with the surface of the needling platform, so that the needle 301 can pass through the blind hole 601 without hindrance, and in order to ensure that the needle 301 can pass through the needle channel 101 and the blind hole 601 smoothly and without interference when the positions of the needle channel 101 and the blind hole 601 are changed, the aperture of the blind hole 601 should be larger than that of the needle channel 101 (higher than the aperture difference between the two in embodiment 2).
