The automatic conveying of the conveyor belt reduces the number of times workers manually carry plastic bags, thereby reducing labor intensity. At the same time, it can ensure that each plastic bag is delivered to the next link in accordance with certain specifications, avoiding the impact of human factors on packaging quality, thereby improving the quality consistency of the final product. The repeated pushing of the push plate ensures that the rolled plastic bags are always located at the center of the conveyor belt to avoid deviation, reducing the risk of equipment failure or bag falling due to deviation, and ensuring that the bags move stably during the entire conveying process to avoid jamming or unevenness, thereby improving the overall efficiency of the production line.

[0015] (2) The invention reasonably controls the inflow and outflow of plastic bags by opening the channel back and forth, thereby ensuring that the working rhythm of each link in the production line remains consistent, avoiding congestion or idleness, and ensuring that production will not stagnate due to excessive or insufficient accumulation of plastic bags, thereby reducing waiting time and maintaining the continuity of the production process. By moving the push plate 2 backward, the rolled plastic bags on the fixed plate are pushed into the channel of the feed box, ensuring that the plastic bags can enter the channel continuously and evenly, reducing the production stagnation time caused by accumulation, thereby improving the overall production efficiency, and avoiding excessive accumulation of plastic bags near the channel of the feed box, thereby ensuring a balanced supply of plastic bags in subsequent processing or production processes.

[0016] (3) The invention can effectively push the plastic bag from the channel of the feed box to the designated position of the conveying device by moving the push plate to the right when the plastic bag falls onto the conveyor belt through the channel, thereby ensuring that the plastic bag falls accurately on the surface of the conveyor belt or other conveying devices and preventing the plastic bag from stagnating or being delayed at the feed port, thereby improving the conveying efficiency of the entire production line. By moving the moving plate forward, the plastic bag is prevented from directly impacting the surface of the conveying device, thereby reducing wear and damage to the conveying device and avoiding waste caused by inaccurate or uneven falling of the plastic bag.
