Braking adjustor for textile guide roller of spreading machine

摘要

The present invention can adjust the braking force of the fabric guide roller for guiding the fabric to improve the reliability of the operation by distinguishing the rotation / stop operation of the fabric guide roller, and part of the fabric by its own weight The present invention relates to a braking force adjusting device for a fabric guide roller of a stepper to prevent it from flowing down, one end of which is coaxially coupled to the fabric guide roller (40), and a sliding keyway (52) is formed at the other end of the opposite side. In the end face of the bearing supporter 60 with the screw shaft 50 formed in the direction, a bearing supporter 60 provided on the frame 42 to guide the screw shaft 50, and a friction pad 72 therebetween. A cross section of the bearing supporter 60 in contact with the pressure ring 70, the set screw 74 installed in the pressure ring 70 and linearly guided in the axial direction along the sliding keyway 52, and the pressure ring 70. Preload to pressurize Screwing to the screw shaft 50 to fix the adjustment nut 90 and the adjustment nut 90 for adjusting the pressing force of the preload spring 80 is screwed to the spring 80, the screw shaft 50 The lock nut 92 and the snap ring 100 which is in contact with the inner ring side of the bearing 62 installed on the bearing supporter 60 and installed on the screw shaft 50.
