[0005] Side positioning modules are symmetrically arranged on the vertical guide columns to realize the positioning of both ends of the box body;

[0006] Rotary box closing modules are symmetrically arranged at both ends of the lifting plate to realize the closing of the side covers of the box body.

[0007] Among them: the side positioning module includes a side support seat installed on the vertical guide column, a side positioning cylinder installed on the side support seat, and a side positioning plate driven by the side positioning cylinder.

[0008] Furthermore: limit modules corresponding to the side positioning modules on both sides are symmetrically installed on the lifting plate;

[0009] The limit module includes a horizontal adjustment cylinder installed on the lifting plate and a guide plate driven by the horizontal adjustment cylinder. The guide plate is located outside the corresponding side ear.

[0010] Among them: the rotary box closing module includes a rotary cylinder installed at the end of the lifting plate through a rotary mounting bracket, a rotary bracket driven by the rotary cylinder, and a suction cup arranged on the rotary bracket and corresponding to the side cover of the box body.

[0011] Furthermore: the rotary box closing module further includes a limit block corresponding to the rotary bracket.

[0012] Compared with the prior art, the utility model can realize the automatic closing of the box cover without deformation of the box closing appearance and other bad conditions. It can not only effectively replace the existing manual box closing method, but also realize the effective matching with the automated production line, thus greatly improving the production efficiency.

[0015] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model.

[0016] Please refer to Figure 1 , this embodiment provides an automatic box closing mechanism, which includes a support bottom plate 10 and a support top plate 12 arranged in parallel, and vertical guide posts 11 vertically installed between the support bottom plate 10 and the support top plate 12; a lifting plate 15 is also arranged between the support bottom plate 10 and the support top plate 12. The lifting plate 15 is slidably connected to the vertical guide posts 11 through guide sleeves 13 and is driven to lift by a lifting cylinder 14 installed on the support top plate 12, and side ears 20 are symmetrically arranged at both ends of the lower side surface of the lifting plate 15; side edge positioning modules are symmetrically arranged on the vertical guide posts 11 to realize the positioning of both ends of the box body; rotary box closing modules are symmetrically arranged at both ends of the lifting plate 15 to realize the closing of the side covers of the box body.

[0017] Among them: the side edge positioning module includes a side support seat 16 installed on the vertical guide post 11, a side positioning cylinder 17 installed on the side support seat 16, and a side positioning plate 18 driven by the side positioning cylinder 17.

[0018] Among them: limit modules corresponding to the side edge positioning modules on both sides are symmetrically installed on the lifting plate 15; the limit module includes a horizontal adjustment cylinder 19 installed on the lifting plate 15, and a guide plate 25 driven by the horizontal adjustment cylinder 19. The guide plate 25 is located outside the corresponding side ear 20.

[0019] Among them: The rotating box-closing module includes a rotating cylinder 22 installed at the end of the lifting plate 15 through a rotating mounting bracket 21, a rotating bracket 23 driven by the rotating cylinder 22, and a suction cup 24 provided on the rotating bracket and corresponding to the side cover of the box body; the rotating box-closing module further includes a limit block corresponding to the rotating bracket 23.

[0020] When this embodiment works:

[0021] First, based on the size of the box body, the distance between the guide plate 25 and the side ear 20 is adjusted by the horizontal adjustment cylinder 19.

[0022] After the product is in place, the lifting plate 15 is driven to descend by the lifting cylinder 14, and then the side ears 20 on both sides are synchronously inserted into the inner sides of the two ends of the box body and limited on the outside by the guide plate 25 to avoid damage to the box and mechanical failures caused by incorrect insertion positions of the side ears 20.

[0023] Finally, after the side cover of the packaging box is adsorbed by the suction cup 24, the rotating bracket 23 is driven to rotate by the rotating cylinder 22, thereby realizing the adsorption and traction closing of the side cover.
