It can be understood that the pressing position of the pressing block 5031 of the present invention is close to the position where the package strip is attached to the package, and this design can effectively improve the pressure maintaining effect.

With reference to fig. 1, the box sealing apparatus 1 further includes a blanking device 60 for removing the packaged box.

Further, the box sealing apparatus 1 further comprises a label peeling device 70 for providing the sealing label to the labeling device 30.

Further, the label peeling device 70 includes a conveyor belt for transporting the peeled packaging label to a corresponding station of the labeling device 30.

Referring to fig. 1 to 13, a second embodiment of the present invention provides a box sealing process for sealing a packing box by the box sealing apparatus, including the following steps:

s1: acquiring a box cover and a box body of a box to be sealed;

s2: transporting the transport jig with the box cover and the box body to a first preset position, and carrying out first labeling operation on the box cover;

s3: conveying the box cover and the box body which finish the first labeling operation to a second preset position, and covering the box cover which finishes the first labeling operation on the box body;

s4: sticking the second end of the packaging adhesive strip to the bottom surface of the box body to complete the fixation of the box cover and the box body; and carrying out second labeling operation on the packaging box to finish the fixation of the box cover and the box body.

Further, step S1 indicates that the box cover and the box body of the box to be sealed are moved to the transportation jig, and specifically includes the following steps:

step S11: opening the self-adaptive clamping assembly on the transportation jig through the unlocking device;

step S12: and moving a group of box bodies to be packaged and the closing cover together through the material taking device and placing the box bodies and the closing cover on the transportation jig.

Step S13: and withdrawing the unlocking device to enable the positioning correction device to recover to a conventional clamping state, and adjusting the relative positions of the positioning correction device, the box body and the box cover through a self-adaptive function in the clamping process so as to correct the relative positions of the box body, the box cover and the transportation jig.

Further, step S2 is to transport the box cover and the box body to a preset labeling device, and stick the first end of the packaging sticker to the inner side surface of the box cover, which specifically includes the following steps:

step S21: the two-in-one packaging label is peeled off from the coiled material to the conveying belt through the label peeling device, and the peeled two-in-one packaging label is conveyed to the labeling station through the conveying belt.

Step S22: sucking the two integrated packaging tape strips through a labeling device;

step S23: the two integrated packaging label strips are separated into two packaging label strips by rotating the first labeler and the second labeler;

step S24: sequentially or simultaneously pasting the two separated packaging pasting strips on the pasting position of the inner side surface of the box cover;

specifically, in this embodiment, the mounting positions are two opposite inner side surfaces of the box cover.

Furthermore, each time of mounting, the corresponding side face of the box cover and the corresponding packaging adhesive tape are subjected to azimuth calibration through the visual assembly.

Specifically, in this embodiment, the connecting bracket is slightly rotated to achieve the calibration by matching the connecting bracket with the visual component.

It can be understood that in the box sealing process of the invention, the packaging adhesive strips are sequentially adhered on the two inner side walls of the box cover, and because the packaging adhesive strips are the inner side surfaces of the adhering and checking draft, the design can avoid the box cover from being broken in the process of adhering the packaging adhesive strips; before bonding at every time, the positions of the packaging adhesive tape and the side wall of the box cover on one side are detected and calibrated independently, the influence of previous bonding on next bonding can be avoided, and the bonding error is reduced.

Further, step S3 indicates that the box cover and the box body adhered with the packaging attachment strip are transported to the cover closing device, and the box cover adhered with the packaging attachment strip is closed to the box body, which specifically includes the following steps:

step S31: the box cover is turned to the opening corresponding to the opening of the box body through the first working end group or the second working end group in the turning assembly;

further, when overturning, the box cover needs to be lifted first, so that the box cover is separated from the placing jig.

Step S32: detecting products in the box body;

it can be understood that in the box sealing process, before the box cover after being turned over is closed on the box body, products in the box body can be detected, whether the number and the types of the products in the box body are correct or not is guaranteed, errors are avoided, the reject ratio is reduced, and the user experience is improved.

Step S33: and closing the turned box cover on the box body.

Further, before the box cover is closed on the box body, the part of the packaging attachment strip which is not adhered needs to be adjusted through the attachment strip adjusting component. It can be understood that, in the scheme of packaging a part of the packaging box, only one part of the packaging strip is attached to the inner side of the box cover, and the other part of the packaging strip is attached to the bottom of the box body, so that when the packaging box is covered, a part of the area of the packaging strip needs to be exposed after the covering is completed, and the strip adjusting component can adjust the position of the packaging strip to prevent the packaging strip from being covered inside the box body.

Further, step S4 specifically includes the following steps:

step S41: and the exposed part of the packaging adhesive strip is rolled and adhered to the bottom surface of the box body through the rolling and adhering component.

Step S42: and applying preset pressure to the packaging box which is completely closed from at least two opposite directions through the pressure maintaining device and keeping the preset pressure for a preset time.

And step S43, taking the packaging box subjected to pressure maintaining away from the transportation jig.
