Slackening preventing device for strand take-off device

Abstract

(57)【要約】 (修正有) 【課題】 押し出し機より押し出されたストランドを弛 みがなく正常な状態でペレタイザーに送り出すこと。 【解決手段】 引取機本体1には、上部に相対向して並 設したストランド10の案内ロール2,3を設け、引取 機本体の上部に支柱を設ける。支柱に昇降杆8を有する エアーシリンダー7を装着し、昇降杆の下部に昇降押圧 ロール5を装設する。昇降押圧ロールは並設する該案内 ロールの上方の略中間部分に位置させる。
PROBLEM TO BE SOLVED: To always secure constant traveling so as to make uniform pellets by providing opposing strand guide rolls in a take-off machine main body positioned in the front of a pelletizer and a vertical movement press roll in the upper side of a strut erected in the upper part of the take-off machine main body via a vertically moving stick. SOLUTION: A take-off machine main body 1 includes guide rolls 2 and 3, strands 10,..., passing through the upper parts thereof, and an air cylinder 7 housing a vertically moving stick 8 provided in an upper side more than a strut. A vertical movement press roll 5 is axially fixed to the lower part of the vertical moving stick 8 so as to be freely rotated, and this vertical movement press roll 5 is disposed in the upper side of an intermediate portion between the guide rolls 2 and 3. The take-off machine main body 1 further includes a feed roll 11 for feeding the strands 10,..., and a motor 12 for rotating the same, an injection cylinder 16 having a nozzle 17 in its tip is provided in a push-out machine 15 and a pelletizer 18 is disposed before the strands 10 fed from the take-off machine main body 1.
