[0041] In this embodiment: Based on this arrangement, the tape roll 303 on the bottom surface of the slide plate 302 slides to one side, stretches the tape, and covers the surface of the folded packaging box tongue. Under the action of the electric telescopic rod 32, the tape roll 303 can continue to be pushed to slide to one side. At the same time, the two T-shaped connecting rods 33 installed on the pressure plate 309 can drive the pressing side roller 36 installed at one end thereof to move downward, press down the tape on one side surface of the packaging box, and flatten the tape on both sides to ensure the adhesion between the tape and the packaging box.

[0042] In an optional embodiment: a fixing rod 34 is provided through the through hole opened at one end of the T-shaped connecting rod 33, the fixing rod 34 is installed in a blind groove opened on the bottom surface of the pressure plate 309, and a spring three 35 is sleeved on the outer surface of the fixing rod 34, one end of the spring three 35 abuts against the blind groove opened on the bottom surface of the pressure plate 309, and the other end of the spring three 35 abuts against the T-shaped connecting rod 33, and a cutter 37 is installed on one side of one of the pressing side rollers 36.

[0043] In the present embodiment: Based on this arrangement, when the pressing side roller 36 moves downward and contacts the surface of the packaging box, the packaging box can apply pressure to the two pressing side rollers 36 on both sides, and the two pressing side rollers 36 are ensured to be in an elastic contact state between the pressing side rollers 36 and the packaging box under the elasticity of the spring three 35, so that the tapes on both sides of the packaging box can be more firmly bonded to the packaging box, and at the same time, when the pressing side rollers 36 are pressed downward, the inclination angle of the tape can be changed. When the moving angle is reached, the cutter 37 arranged on one side of the pressing side roller 36 can cut the tape, thereby achieving the purpose of sealing the packaging box.

[0044] It should be noted that: the distance between the two pressing side rollers 36 is slightly smaller than the size of the packaging box. At the same time, the arc-shaped roller frame facilitates the two pressing side rollers 36 to move to one side. The two pressing side rollers 36 can be fine-tuned to both sides under the action of the downward pressure and the horizontal force of the packaging box, and the elastically set pressing side rollers 36 can flatten the tape on the side of the packaging box.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
