1. A thin film sheet manufacturing apparatus comprising:
an extruder (A) for extruding rubber or synthetic resin to mold a thin film sheet (1) of a strip type; a cooling water tank (C) of a box form of which upper side is opened, the cooling water tank (C) storing cooling water therein to water-cool the thin film sheet (1) extruded in the extruder (A); a dehydration tank (D) of a barrel shape of which upper side is opened, the dehydration tank (D) having a punched plate (71), which is arranged inside the dehydration tank (D) and has a plurality of drain holes (71a) perforating the upper and lower sides thereof in order to remove moisture stained on the thin film sheet (1) passed the cooling water tank (C); a dehydrator (E) for second removing the moisture stained on the thin film sheet (1) passing the dehydration tank (D); and a winder (F) for winding the thin film sheet (1) passing the dehydrator (E), wherein the dehydrator (E) includes: a support frame (81) extending back and forth; a transferring roller (82) which is disposed on the support frame (81) and driven by a driving motor (82a) to transfer the thin film sheet (1); upper and lower air blowing pipes (83, 84) which are disposed in front of the transferring roller (82) to be located at the upper and lower sides of the thin film sheet (1) and have air vents (83a, 84a) formed in the circumferential surface and opened toward the thin film sheet (1); an air blower (85) connected to the upper and lower air blowing pipes (83, 84) to supply air of high pressure to the upper and lower air blowing pipes (83, 84); and a plurality of support rollers (86, 87) which are disposed in front of the upper and lower air blowing pipes (83, 84) for supporting the thin film sheet (1) to be supplied between the upper and lower air blowing pipes (83, 84). |
