Towing Rope Tension Adjuster

Towing Rope Tension Adjuster Using Multi-Stage Rollers and Elastic Members

This technology relates to a towing rope tension adjuster. Specifically, it is designed for use with greenhouse thermal curtains that move longitudinally to open and close. The device maintains constant tension on the towing rope—which is attached to one end of the curtain and wound or unwound by a drum—to prevent the rope from tangling or overlapping during operation. By ensuring the rope is wound and unwound with consistent tension, this invention allows for sequential winding and unwinding, preventing tangles or breakage and ensuring smooth operation of the greenhouse thermal curtain system.

Existing solutions in this field have faced structural and functional limitations that required improvement.

This towing rope tension adjuster can be applied across relevant industries to enhance performance and efficiency.

Key Features:

• A roller unit consisting of first, second, and third rollers positioned at vertical intervals, suspended and installed on the towing rope support guide pipe.
• A pipe-fixing hook composed of one or more loops, installed above the first roller to secure the device to the pipe.
• First and second fixing plates, each fitted and secured to both sides of the roller rotation shafts, featuring through-holes for the rotation shafts.
• An elastic member for tension adjustment that provides elastic force to deflect the rollers at a specific angle, thereby regulating the tension of the towing rope.
