The case body 1 is a cuboid integrally-formed structure and is composed of a case outer plate 11 and a case inner plate 12, a case hot air layer 13 is formed between the case outer plate 11 and the case inner plate 12, and a case inner cavity 14 is formed inside the case inner plate.

A cloth inlet and a cloth outlet are respectively transversely arranged on the opposite surface of the case body 1 and are respectively used for feeding and discharging cloth. The cloth inlet is transversely provided with a cloth inlet roller 6, the cloth outlet is transversely provided with a cloth outlet roller 7, and the cloth inlet roller 6 and the cloth outlet roller 7 are used for driving cloth to enter and exit.

Six circular nets 2 are arranged in the inner cavity 14 of the case, and the circular nets 2 are uniformly arranged in parallel with the cloth inlet roller 6 to the cloth outlet roller 7. The cloth feeding roller 6 and the cloth discharging roller 7 drive the spunlace nonwoven cloth to be dried to be formed in the case body 1: the process of cloth feeding → back side → front side → cloth discharging, thus increasing the detention time of the spunlace cloth in the cylinder mould drying machine, improving the drying capability of the machine and increasing the yield while not increasing the drying temperature to prevent the deformation of the material. The outer surface of the rotary screen 2 adopts the annular jointless stainless steel wire mesh, so that the spunlace cloth can be prevented from being hung and damaged, and the surface of the spunlace cloth is smooth and has no reticulate pattern print; the stainless steel honeycomb net with high air permeability and high bearing strength is adopted below the stainless steel net, so that the mechanical strength of the whole circular net is higher, as shown in fig. 5.
