It has the advantages of simple structure, small footprint, flexible adjustment, etc.

[0045] The working principle of the utility model is as follows:

[0046] When the material is conveyed into the rotary bag-turning device, the lifting mechanism drives the bag-turning mechanism to move to a suitable position as a whole, and then the clamping driving member drives the clamping member to firmly clamp the material;

[0047] Then, the lifting mechanism drives the bag-inverting mechanism to move upward and away from the conveyor, and the rotary drive mechanism drives the bag-clamping mechanism to rotate horizontally as a whole to adjust the posture of clamping the material;

[0048] Subsequently, the lifting mechanism drives the bag-inverting mechanism to move downward as a whole, and the clamping driving member drives the clamping member to open so that the material is out of the clamping state, thus completing the posture adjustment;

[0049] Finally, the rotary drive mechanism drives the bag clamping mechanism to rotate back to the original state, and continues to repeat the above operation process for the next material.

[0062] After the bag clamping mechanism reaches a suitable height, the clamping driving member drives the clamping member to close to firmly clamp the packaging bag;
