[0002] As one of the main packaging forms, flour bags are widely used in food processing, household consumption and commercial supply chains. They carry the functions of transporting, storing and distributing flour. Flour bags are usually made of paper, plastic or composite materials to ensure good strength and moisture resistance during transportation.

[0018] By starting the third motor to drive the second gear to rotate, the second gear and the rack cooperate with each other, thereby synchronously driving the rack to rotate on the inner wall of the fixed block. Under the mutual cooperation of multiple half gears and the inner gear ring, the half gears can be rotated synchronously, and the baffle is driven to open through the limiting effect of the positioning rod, so that the conveying size can be conveniently adjusted.

[0019] The present invention provides a flour bag opening mechanism, which has the following beneficial effects:

[0020] 1. The present invention drives the circulation pipeline to rise and fall through the electric slider, so that the movable ring moves, thereby pushing the connecting rotating block and the positioning rotating block to unfold the support plate, thereby opening the mouth of the flour bag, and cooperating with the electric telescopic rod to drive the limit slider to fit with the clamping plate to firmly clamp the mouth of the flour bag, thereby ensuring the stability of the flour bag during the filling process, preventing the bag mouth from slipping or tipping over, and improving the stability and safety of the operation.

[0021] 2. The present invention drives the first gear to cooperate with the limiting gear ring through the second motor, so that the limiting gear ring drives the rotating blade to rotate. The rotating blade is located at the bottom of the funnel, which effectively avoids the blockage of materials at the conveying port, avoids shutdown or failure caused by flour blockage, and improves the conveying efficiency and stability of the equipment.

[0022] 3. After the third motor is started, the second gear and the rack cooperate with each other to push the inner gear ring to rotate, thereby driving multiple half gears to cooperate with the inner gear ring, so that the half gears rotate synchronously, thereby opening or closing the baffle. In this way, the width of the conveying port is changed by the opening and closing degree of the baffle, so that the conveying size can be conveniently adjusted. BRIEF DESCRIPTION OF THE DRAWINGS
