cloth pulling conveying motor 15 of the cloth pulling conveying mechanism 3 and the push rod driving motor 48 of the disc positioning mechanism 4 are servo motors to realize stable and accurate intermittent sectional conveying of melt-spraying cloth, and the swinging push rod 68 is arranged on the upper side of the, in the process that the reciprocating positioning guide rod 45 slides upwards along the vertical direction, the push rod swinging roller 68 can be used for conveniently and smoothly pushing the disc to block the swing rod 49 from swinging clockwise. Through the structure, the intermittent sectional drawing conveying device is reasonable in structural design, can efficiently and stably draw and convey the melt-blown fabric in a sectional manner, improves the automation degree of the melt-blown fabric conveying, and meets the requirements of production and use.

The above description of the present invention is intended to be illustrative. Various modifications, additions and substitutions for the specific embodiments described may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
