The utility model discloses baling equipment's work flow as follows: conveying or transporting the blocks such as books and periodicals to be packaged to the input mechanism, and orderly stacking the blocks by the input mechanism; the blocks are conveyed to a sheet conveying mechanism through a conveying belt 40, the sheet conveying mechanism cuts roll packing paper such as kraft paper into single packing paper according to the packing requirement of length, width and height, and the packing paper is wound around the whole bodies of the blocks to form a sheet roll structure 30; the sheet roll structure 30 in the semi-wrapped state continues to be fed into the creasing mechanism and stops when it reaches a position between the forward extending panel 25 and the side creasing panel 22. The first front air blowing pipe 111 and the second front air blowing pipe 113 synchronously blow air to the sheet roll structure 30, front kraft paper wound on the package is blown to the direction of the to-be-folded edge, and then the first side folding plate and the second side folding plate fold and press the front ear at the end part of the sheet roll structure 30 to the side surface attached to the book and periodical small bag. Then, the front air blowing pipe 11 stops blowing air, and the first side folding plate and the second side folding plate are reset. The first rear air blowing pipe 131 and the second rear air blowing pipe 133 start to blow air to the sheet roll structure 30, and the rear kraft paper wound on the package is blown to the direction of the to-be-folded edge; the first forward extending plate 25 and the second forward extending plate 25 symmetrically move to the width surface of the small book pocket along the transverse direction, then move forward along the conveying direction, fold and press the rear ear at the end part of the sheet roll structure 30 to be attached to the side surface of the book, the rear air blowing pipe 13 stops blowing air, and the first forward extending plate 25 and the second forward extending plate 25 reset. Subsequently, the lower edge folding mechanism and the upper edge folding mechanism act to fold and press the upper ear and the lower ear at the end of the sheet rolling structure 30 to the side surfaces attached to the block-shaped packages and press the folded front ear and the folded back ear. Then, the whole package is continuously conveyed to the rear section for bundling or gluing, and the whole packaging process is completed.

The above only is the preferred embodiment of the present invention, not so limiting the patent scope of the present invention, all under the concept of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings is utilized, or the direct/indirect application is included in other related technical fields in the patent protection scope of the present invention.
