The nanofiber manufacturing device (1) is equipped with a transfer device (10), a plurality of field emission devices (20), and a main control device (60) controlling the movements of the transfer device (10) and the plurality of field emission devices (20), wherein the main control device (60) monitors the amperage supplied by each of power devices for each of the field emission devices (20), and at the same time, when a current greater than the predetermined set amperage is detected to be supplied by one or a plurality of power devices, transmits a signal to stop the current supply from the corresponding one or the plurality of power devices, and simultaneously transmits a signal for decreasing the transfer speed of the transfer device (10) to put into predetermined range the cumulative accumulation amount of the nanofibers per unit area of accumulation on the long sheets (W).
The present invention enables appropriate maintenance of at least one of environment humidity or environment temperature of a field emission device over a long period of time. The nanofiber manufacturing device (1) is equipped with a field emission device (20) for emitting nanofibers, a air supply device (70) for supplying environment-adjusted air to the field emission device (20), and a volatile component (VOC) processing device (60) for combusting and eliminating VOC generated from the field emission device (20), wherein the air supply device (70) has a dehumidifying device for generating dehumidified air dehumidified by a dehumidifying agent dried by warm air generated by the heat of combustion generated when combusting VOC using VOC processing device (60).
The present invention relates to a device for preventing the drooping of Tomson paper for a caser, and the device comprises: a base (10) which is fixed to four places in every direction on a frame of a lower mold device (5) of a caser (1); a guide rail (11) which is fixed to the top of said base (10) by a fastening screw (12); an air cylinder (15) which is fixed to a supporter that is (13) fixed to the top of said base (10) through a fastening screw (14), and has a piston rod (16); a slider (22) which is assembled on said guide rail (11), in which a bracket (23) for assembling a support plate (27) is fixed to an upper side thereof, and in which a bolt (25) for fixing a coil spring (26) that controls an angle of the support plate (27) is assembled on the rear part of the bracket (23); a joint (17) which is fixed to the front of said slider (22), and fixes said piston rod (16) by a nut (18); the support plate (27) in which a bracket (28) fixed to the bracket (23) of said slider (22) through a fastening bolt (24) is fixed to a lower side thereof, and in which an upward bending end (27a) for supporting the Tomson paper is formed on the front; the coil spring (26) which is assembled between said slider (22) and the support plate (27), and applies a force that always lowers the upward bending end (27a) of the support plate (27); a roller (21) which is fixed by a fastening pin (20) to an upper side of a vertical part (19) that is fixed to said base (10); and a placing part (29) which is fixed to a lower side of said support plate (27) through a fastening screw (30), and in which an inclined surface (29a) is formed on a side that faces said roller (21).
