Title:
AUTOMATIC BALANCE ADJUSTMENT DEVICE FOR HORIZONTAL TENSION OF RAW MATERIAL USING ROLLER
Document Type and Number:
WIPO Patent Application WO/2015/037757
Kind Code:
A1
Abstract:
Disclosed is an automatic balance adjustment device for the horizontal tension of a raw material using a roller, which controls the tension of a transfer roller with a roller axis protruding from both sides thereof in which a raw material is transferred. The automatic balance adjustment device includes: a left side tension controller (20) in which a left side roller axis (11) protruding from the left side of the transfer roller (10) is combined; and a right side tension controller (30) in which a right side roller axis (12) protruding from the right side of the transfer roller (10) is combined. The left side tension controller (20) and the right side tension controller (30) move the left side roller axis (11) and the right side roller axis (12) in a symmetrical direction and control the tension of the transfer roller by symmetrically moving the left side roller axis (11) and the right side roller axis (12) in left, right, upper, and lower directions. The present invention as above may minimize a warp phenomenon generated in the transfer of the raw material because the right side tension controller and the left side tension controller are respectively combined to the left and right sides of the transfer roller axis of the transfer roller in which the raw material is transferred. The present invention smoothly controls the tension of the transfer roller by a seesaw principle because the tension of the transfer roller is controlled in the left, right, upper, and lower directions. The present invention further includes left and right movement direction control pieces and thus may move the transfer roller axis to be tilted, thereby controlling the tension by various directivity.
