Automatic gel ribbon thickness adjustment device

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.
