Description

Technical Field

[0001] The utility model relates to the technical field of intermittent cartoning machines, in particular to an auxiliary box covering device and an intermittent cartoning machine. Background Art

[0002] The existing intermittent cartoning machine mainly goes through the steps of opening, loading and closing the box. Opening the box means unfolding the folded carton into shape, loading the box means loading the material into the box body of the carton. The opening of the carton is provided with side wings and main wings, and closing the box means folding the side wings and main wings to achieve the packaging of the carton.

[0003] After the box loading step is completed, the paper box containing materials needs to be intermittently advanced to multiple stations before the box closing step can be performed. Since the side wings and the main wing have not been folded, during the material transportation process after box loading and before box closing, if the materials are scattered items, the materials in the paper box are easy to slide off one side of the paper box. In addition, during the box closing process, after folding one side wing of the paper box, the other side wing cannot be folded in time, and there will be a problem of materials sliding off one side of the paper box, which will cause the paper box to be short of materials or the materials to be stuck on the frame.

[0032] like Figure 1 to Figure 2As shown, the utility model provides an auxiliary box cover device, which is used for auxiliary box cover of a paper box 100 containing a material 101 and transported along a first direction X. The auxiliary box cover device comprises a rear wing box cover assembly 1 and a front wing box cover assembly 2. The rear wing box cover assembly 1 comprises a driving member 11 and a dial wheel 12. The driving member 11 is used to drive the dial wheel 12 to rotate. The dial wheel 12 comprises a lever 121. During the rotation of the dial wheel 12, the lever 121 can bend the rear wing 102 of the paper box 100 toward the inner cavity of the paper box 100, and can resist the outer side of the bent rear wing 102; the front wing box cover assembly 2 is arranged downstream of the rear wing box cover assembly 1 along the first direction X, and the front wing box cover assembly 2 comprises a side guard assembly 21 arranged along the first direction X.
