特徴とする押出成形用ダイリツプ調整装置。 A thermal displacement type lip adjustment device is installed in multiple die lips in the width direction of a die for extruding molten resin sheet (or film) and adjusts the lip gap by thermal expansion and contraction of adjustment bolts, which pushes and pulls the die lip. A lip adjustment bolt is provided for the die lip, and a cylindrical heater is provided to heat the bolt, and the heater is arranged so that the lip adjustment bolt is directly heated, and the lip adjustment bolt is fastened to the die lip via a heat insulating material. An adjustment screw is provided at the other end, and a cooling supply/exhaust passage is provided at the center of the adjustment bolt, and a front heater is installed on the outside of the die to prevent temperature fluctuations due to the flow of outside air and heat dissipation. A die lip adjustment device for extrusion molding characterized by being equipped with a screen.
