[0009] Preferably, the carrier rollers and the pressure rollers of the heating roller group are water circulation heating rollers, heat conduction oil circulation heating rollers, steam heating rollers or electromagnetic induction heating rollers.

[0010] Preferably, the number of the groups of the re-pressing rollers is not less than two.

[0011] Preferably, the included angle between the spraying port on the spraying pipe and the surgical drape is 30°-60°.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The pre-pressing roller group, the heating roller group and the re-pressing roller group each comprise carrier rollers and pressure rollers which are clamped and rolling connected with each other, and the two sides of the folded surgical drape are limited during the conveying process, the effect of ironing is achieved through the humidification of the humidifier and the heating of the heating roller group, and on the basis of the heating roller group, a plurality of re-pressing roller groups are additionally arranged to extrude and keep the shape, so that the folded surgical drape is kept flat during the conveying process and the subsequent cutting section is neat, thereby solving the problems that the folded surgical drape in the prior art has no side limiting measure and is prone to cause errors in the interval of each layer of wrinkles, the side folding is not neat and the subsequent cutting section is not straight during the subsequent conveying.
