1. An automatic gel ribbon thickness adjustment device which controlling a thickness of a gel ribbon, the automatic gel ribbon thickness adjustment device comprising:
a driving device disposed on a spreader box for supplying liquid gelatin to a casting drum by spreading the liquid gelatin in a sheet form, a blocking plate of the spreader box being moved vertically by the driving device to adjust an opening width of an outlet;
a thickness measurement device disposed on a path through which the gel ribbon in the casting drum guided by a first guide roller is supplied to a forming machine; and
a controller configured to, based on information measured through the thickness measurement device, control the driving device disposed on the spreader box;
a fixing rod disposed in a horizontal direction on an upper rear portion of the blocking plate of the spreader box;
support rods; and
an assembling member,
wherein extension portions are provided on left and right sidewalls of the spreader box to protrude rearward of the blocking plate,
wherein the support rods crossing the blocking plate are fixed to the extension portions on the left and right sidewalls, respectively, in a state where the support rods are positioned below the fixing rod to correspond to the fixing rod,
wherein the assembling member is disposed in a space between the fixing rod and the support rod, which are positionally corresponding to each other, while being supported by an elastic body,
wherein the blocking plate is elastically supported on a box body having a hollow portion and the blocking plate is movable vertically,
wherein the driving device presses the elastically supported blocking plate to adjust the thickness of the gel ribbon while adjusting the opening width of the outlet,
wherein the driving device includes a plurality of driving motors on a mounting plate which is laterally formed by a length between the extension portions on the left and right sidewalls,
wherein each moving shaft of the driving motors protrudes downward at a same time when each driving motor is operated so that the fixing rod is pressed to move the blocking plate downward,
wherein support portions are formed by downwardly bending left and right side ends of the mounting plate corresponding to the extension portions, and
wherein the support portions are detachably assembled using a fastener in a state where the support portions are placed on the extension portions, respectively.
