Beam, force cell is additionally provided with the tensioning module.
Further, motor and belt support wheel, the master installed on the motor output shaft are housed on the outside of the tensioning beam
Driving wheel and belt support wheel are propped up belt is locked, and the position of the locking belt is relative with the locknut position on the tension rod
Should.
Further, the top of the jack is connected by one end of connector and tension rod, and the connector passes through
The internal thread hole at both ends is connected respectively with jack and tension rod.
The present invention has the advantages and positive effects of：Above-mentioned technical proposal, using simultaneously complete single deformed bar
Synchronous tension, single standalone sensor controls stretching force, auto lock stretching force after the completion of automatic Tensioning, realizes stretching force
Value it is uniform, stably, small error, automation instead of manual operation, improves operating accuracy, improve production efficiency, drop
Low production cost.
