The bagging mechanism that above-mentioned embodiment provided, through closing bagging apparatus 70 in advancing bag sealing station department setting, after in the wrapping bag of appointed quantity material propelling charge, close bagging apparatus 70 can close bag pole 72 through the drive of rotary driving piece 71 and rotate mutually in opposite directions extremely in the target wrapping bag, the end of closing bag pole 72 supports respectively and leans on the internal surface at the opening part of target wrapping bag, is used for the tensioning open a bag board of target wrapping bag withdraws from behind the target wrapping bag, the drive of rotary driving piece 71 close bag pole 72 and continue opposite directions motion tensile the target wrapping bag is closed up to the opening to follow-up target wrapping bag execution automatic sealing operation after closing has been solved a key ring in the automatic packaging operation full-flow of material.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. The protection scope of the present invention shall be subject to the protection scope of the claims.
