and a preload spring (1004) provided between the outer end of the floating seal block (1003) and the upper seal groove (1001).
10. A drawing process suitable for an IXPP foam drawing apparatus as defined in any one of claims 1 to 9, comprising the steps of:
s1, mounting a foaming cotton roll on an unreeling mechanism (1);
s2, the foam cotton enters a first group of thinning rollers (2022) to be thinned for the first time;
s3, heating and softening the foam cotton which is thinned for the first time between the upper electric heating fin plate (2032) and the lower electric heating fin plate (2033) of the first group;
s4, the foam cotton subjected to primary thinning and heating enters between a second group of thinning rollers (2022) for secondary thinning;
s5, the foam cotton subjected to secondary thinning enters between the upper electric heating fin plate (2032) and the lower electric heating fin plate (2033) of the second group to be heated and softened again;
s6, the foam cotton subjected to secondary thinning and reheating enters between a third group of thinning rollers (2022) to be thinned for three times, so that the finished foam cotton with the required thickness is obtained;
s7, guiding the finished foam cotton by a guiding mechanism (3), and feeding the finished foam cotton into a winding mechanism (4) to be wound into a roll.
