Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic bag processing, in particular to a movable mechanism for receiving plastic bags. Background Art
[0002] When producing and packaging large plastic bags, multiple large plastic bags need to be stacked and then folded as a whole to form portions for individual sale.
[0003] During the process of placing the produced plastic bags on the platform and then waiting for folding. Since the plastic bags are too large, when stacking the plastic bags on a placement platform with one side suspended, the end of the suspended plastic bag is prone to falling and drifting, resulting in uneven stacking. Moreover, the process of rapid stacking causes the lower plastic bags not to fully fall, and is further affected by the upper plastic bags, further affecting the normal stacking of plastic bags; when the plastic bags are stacked flat on the platform, although the stacking effect is guaranteed, the entire plastic bags still need to be removed. The flat plastic bags are not conducive to the manipulator for removal operation. Even if they can be removed, a stacking station and a subsequent folding station need to be set up simultaneously, which increases the production line length and cost, and is not conducive to popularization.

A receiving area formed by a receiving belt fixed to the frame at one end realizes the full reception of plastic bags. Further, through the counterweight on one side of the receiving belt or the elastic recovery of the coil spring, the tensile force on the receiving belt is maintained during the expansion and contraction of the receiving belt. Further, through the notch provided on the output frame, the natural hanging part of the plastic bags is clamped after the reduction of the receiving area.
