【考案の詳細な説明】
本考案は、樹脂フィルムまたはシート成形において、ダ
イスから押出されたフィルムまたはシートの巾方向の温
度を均一に保持する事の出来る温度調節装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a temperature control device that can maintain uniform temperature in the width direction of a film or sheet extruded from a die during resin film or sheet molding.
一般に、樹脂フィルムまたはシートを成形する場合には
、押出機を用いて溶融温度以上の温度に加熱しダイスつ
り押出し、その後に冷却ロールで冷却する方法が採用さ
れている。Generally, when molding a resin film or sheet, a method is employed in which the resin is heated to a temperature higher than the melting temperature using an extruder, extruded through a die, and then cooled with a cooling roll.

樹脂フィルムまたはシートの温度調節装置である。That is, the present invention includes a heating device 10 comprising at least two temperature detection terminals 3 and a heating heater 4 installed in the width direction of both sides of a resin film or sheet 2 extruded from an extrusion die 1, and It consists of a temperature regulator 5 installed between the detection terminal 3 and the heating heater 4,
The temperature controller 5 receives the temperature detected by the temperature detection terminal 3,
This is a temperature control device for a resin film or sheet, which is characterized by adjusting the capacity of the heater 4 to maintain a uniform temperature in the width direction of the resin film or sheet.
以下、本考案をその１実施例を示す添付図面にもとづ゛
いて説明する。The present invention will be described below with reference to the accompanying drawings showing one embodiment thereof.
第１図、第２図は、本考案のシート温度調節装置の側断
面図及び正面断面図である。1 and 2 are a side sectional view and a front sectional view of the seat temperature adjusting device of the present invention.

ター４及び温度調節器５を１組とする８組のシート温度
調節装置を設置しである。The sheet 2 extruded from the extrusion die 1 is cooled by a cooling roll 6, and there are temperature detection terminals 3, heating heaters 4, and temperature control on both upper and lower sides of the sheet 2 in the width direction between the extrusion die 1 and the cooling roll 6. Eight sets of seat temperature control devices are installed, one set being the container 5.
第３図は、加熱装置１０の一部切欠斜視図である。FIG. 3 is a partially cutaway perspective view of the heating device 10.
加熱装置１０の本体枠１４の中央につらぬいて温度検出
端子３を突出させ、その端部はリード線１３によって温
度調節器５に接続されている。A temperature detection terminal 3 is inserted through the center of the main body frame 14 of the heating device 10 and protrudes, and its end is connected to the temperature regulator 5 by a lead wire 13.
また、加熱ヒーター４は、本体枠１４中央巾方向に設置

になる。The sheet 2 extruded from the extrusion die 1 passes between 8 sets of sheet temperature control devices installed on both upper and lower sides of the sheet 2 and in the width direction. Since the temperature controller 5 receives the temperature detected by the temperature detection terminal 3 and adjusts the capacity of the heater 4, the temperature in the width direction of the sheet 2 is maintained uniformly.
従って、本考案によると、前記したような、樹脂フィル
