[0015] The technical advantages of this utility model are as follows: The product has a reasonable and ingenious structure, specifically addressing the problem that existing conveyor structures can only be used with bags of a certain height. By installing a conveyor lifting component at the bottom of the conveyor frame, the height of the conveyor frame can be adjusted, thus accommodating bags of various heights. When the bag height is low, the conveyor frame rises to ensure the bag opening reaches the packaging machine's discharge port; when the bag height is high, the conveyor frame adjusts downwards so that the bag opening is precisely positioned at the packaging machine's discharge port to receive the material. Simultaneously, to ensure reliable and stable conveying of the bags on the conveyor belt after loading, width-adjustable guardrails are installed on both sides of the conveyor frame to limit the width of the loaded bags, thereby ensuring reliable and stable forward conveying.
