AI Technical Summary
Technical Problem
During the unwinding process of woven bags, the bags are prone to shrinking back due to the tension exceeding the friction, resulting in unwinding difficulties.
Method used
An environmentally friendly plastic woven bag processing fixing device was designed. The fixing plate is controlled by a cylinder to drive the second rotating shaft to rotate. The connecting rod drives the pressure plate to flip down and press the woven bag, increasing the friction. The weight of the roller keeps it in close contact as the diameter of the woven bag roll decreases, assisting in unwinding.
Benefits of technology
It effectively avoids the shrinkage of woven bags when pulled, ensuring smooth unwinding and stability of the woven bags, and preventing loosening.

Abstract
This utility model discloses a fixing device for processing environmentally friendly plastic woven bags, relating to the technical field of woven bag processing. The utility model includes a frame, with symmetrically distributed unwinding frames mounted on one side of the frame. Unwinding shafts are mounted on the unwinding frames. Symmetrically distributed support plates are fixed on the side of the frame away from the unwinding frames, with fixing components mounted on the support plates. Auxiliary components are mounted on the unwinding frames. A cylinder controls the fixing plates to drive a second rotating shaft to rotate. The second rotating shaft, through a connecting rod, drives a pressure plate to flip downwards and press the woven bag, thus preventing the woven bag from shrinking back during the conveyor belt of the cutting device, thereby facilitating unwinding. A weight-operated roller rotates downwards around a third rotating shaft, causing the roller to gradually decrease in diameter as the woven bag roll is unwound, maintaining a close fit. This prevents the woven bag roll from becoming loose after being pulled, thus assisting in unwinding.
