Shoe press mechanism of paper machine

Abstract

A shoe press mechanism 100 of a paper machine includes a shoe press 11 , and a press roll 13 disposed so as to face the shoe press 11. A wet paper web to be fed is nipped by the press roll 13 and the press shoe 19 together with an annular belt. The shoe press 11 includes a supporter 15 , a press shoe 19 that is provided to the supporter 15 so as to move in the direction of approaching or being separated from the press roll 13, a pair of supporting disks 21 that is rotatably supported by the supporter 15, an annular belt 23 that is fixed to the supporting disks 21 and is disposed so as to include the press shoe 19 therein, and adjusting stay bars 25 that are disposed parallel to an axis of the annular belt 23. A mounting position of the adjusting stay bar 25 with respect to the supporter 15 can be adjusted, and the tension of the annular belt 23 is adjusted by adjusting the mounting position.

1 . A shoe press mechanism of a paper machine comprising: 
 a press roll;    a supporter of which both ends are fixed to a machine casing;    a press shoe that is provided in the supporter so as to move in the direction of approaching or being separated from the press roll;    a pair of supporting disks which is provided on both sides of the press shoe so as to be rotatably supported by the supporter, respectively;    an annular belt which is disposed so as to include the press shoe therein, of which both ends are fixed to the pair of supporting disks, and which runs while the inner periphery thereof comes in slide contact with the press shoe; and    an adjusting stay bar of which both ends are fixed to the supporter so as to be parallel to an axis of the annular belt, wherein    a wet paper web to be fed by a feeding felt is nipped by the press roll and the press shoe together with the annular belt, and    a mounting position of the adjusting stay bar with respect to the supporter is adjustable, and the tension of the annular belt is adjusted by adjusting the mounting position.    
   
   
       2 . The shoe press mechanism according to  claim 1 , wherein 
 the adjusting stay bar is a straight bar, and    the mounting position thereof is adjusted in the radial direction of the annular belt.    
   
   
       3 . The shoe press mechanism according to  claim 1 , wherein 
 the middle portion of the adjusting stay bar in the axial direction is curved like a bow, and    the tension of the annular belt is adjusted in order to tighten the middle portion of the annular belt in the width direction thereof by adjusting a rotational phase of the adjusting stay bar with respect to the supporter, and then by fixing the adjusting stay bar to the supporter.
