[0021] Referring to the drawings. The embodiment takes the case sealing mechanism for the top of the case as an example, that is, the front and rear pressing wheels 810 and 820 are located at the lower part of the case sealing mechanism. The case sealing mechanism of the case sealing machine comprises a mounting base, which can be a mounting plate 1, and a case sealing assembly, which comprises a front pressing wheel swing rod 81 and a rear pressing wheel swing rod 82, a cutter swing rod 83, a reset mechanism, a front pressing wheel 810 and a rear pressing wheel 820, a tape cutting knife 830, a tape roll mounting part, and a plurality of guide wheels. The tape roll mounting part 302 can be a tape roll mounting shaft, the reference numeral 300 is a tape roll, the reference numeral 301 is a tape running route, the tape roll mounting part 302 is connected with the front pressing wheel swing rod 81, so that the tape roll 300 mounted on the tape roll mounting part 302 can be manually lifted or pressed based on the swing of the front pressing wheel swing rod 81, and after being released, it is driven to swing back by the reset mechanism.

[0022] One end of the front pressing wheel swing rod 81 is provided with the front pressing wheel 810, and the tape roll mounting part 302 is arranged at a position away from the front pressing wheel 810, which satisfies that after the front pressing wheel swing rod 81 is rotated in the direction of moving the front pressing wheel 810 backward (that is, the front pressing wheel swing rod 81 is rotated clockwise around the swing axis 813, and the front pressing wheel 810 moves to the left side), the tape roll 300 mounted on the tape roll mounting part 302 can be located at the frontmost position of the case sealing assembly (that is, the rightmost position in the figure). Figure 1 Figure 1 The operator standing in front of the case sealing machine can directly perform the tape roll mounting and tape threading work on the case sealing assembly on the case sealing machine.

[0023] ​The front pressing belt wheel swing rod 81 is provided with a first belt guide wheel 861 near the position of the rubber belt roll 300, and the rubber belt drawn from the rubber belt roll passes through the first belt guide wheel 861 and is guided, the front pressing belt wheel swing rod 81 is provided with a second belt guide wheel 862 near the position of the front pressing belt wheel 810, and a third belt guide wheel 863 is provided between the second belt guide wheel 862 and the first belt guide wheel 861 on the mounting plate 1, and the rubber belt passes through the third belt guide wheel 863 after passing through the first belt guide wheel 861 and then passes through the second belt guide wheel 862. This arrangement can help to make the rubber belt run smoothly and stably, regardless of the angle change of the front pressing belt wheel swing rod 81, which helps to avoid wrinkles.

[0024] The front pressing belt wheel swing rod 81 is provided with a let go slot 814 which cooperates with the third belt guide wheel 863 provided on the mounting plate 1 to pass the wheel shaft or the component on the wheel shaft of the third belt guide wheel 863. In this way, not only is the setting of the third belt guide wheel convenient, but also the front pressing belt wheel swing rod 81 can be applied to steel plate and can be widened to play a better supporting role for the rubber belt roll and stability during use. As shown in the figure, in this embodiment, part of the steel plate is widened and set 811 as a reinforcing part of the front pressing belt wheel swing rod 81 for reinforcing the structure of supporting the rubber belt roll.

[0025] The sealing box assembly of the embodiment includes the following structures: the front pressing belt wheel swing rod 81, the rear pressing belt wheel swing rod 82 and the cutter swing rod 83 are rotatably installed on the mounting plate 1, the cutter swing rod 83 is provided with a belt cutting knife 830, the front pressing belt wheel swing rod 81 is provided with a front pressing belt wheel 810 on the side away from the mounting plate 1, the rear pressing belt wheel swing rod 82 is provided with a rear pressing belt wheel 820 on the side away from the mounting plate 1, a connecting rod 84 is rotatably connected between the front pressing belt wheel swing rod 81 and the rear pressing belt wheel swing rod 82, a second return spring 85 is connected between the mounting plate 1 and the rear pressing belt wheel swing rod 82, a first return spring 87 is connected between the cutter swing rod 83 and the mounting plate 1, a belt straightening mechanism 88 is further provided on the front pressing belt wheel swing rod 81 between the second belt guide wheel 862 and the front pressing belt wheel 810, the shaft of the cutter swing rod 83 is a fixed shaft 831, and a box pressing plate 89 for the top of the box is installed on the fixed shaft 831.

[0026] The tape straightening mechanism comprises a tape guiding rail 881, and the two sides of the guiding rail 881 are tape edge clamping grooves 882, which can constrain the tape passing through the tape straightening mechanism within the range of the guiding rail 881. A roller 883 with a protruding rail surface is arranged on the rail surface of the guiding rail, so that the middle of the tape passing through the tape straightening mechanism is arched, which helps to prevent the tape from wrinkling when it is attached to the packaging box. The tape straightening mechanism can be implemented in the following structure: the tape straightening mechanism comprises a rail surface component 884 and two side groove wall components 885, which are connected to form the guiding rail 881 and the tape edge clamping grooves 882 on both sides thereof. The rail surface component 884 is bent backward and forms a mounting groove 886 for the roller. The rail surface component 884 is provided with an opening 887 corresponding to the rail surface, which is used to expose the roller 883. The roller shaft 888 is elastically mounted on the back of the position corresponding to the rail surface. The roller shaft 888 can be a flat shaft, which is provided with a hole. A screw 8881 passes through the hole in the flat shaft and is connected with the rail surface component 884. A spring 8882 is sleeved on the screw 8881, so that the roller shaft 888 has a certain elasticity in the direction perpendicular to the axial direction. Thus, the installation size of the structure can be reduced to meet the miniaturized structure arrangement, and the roller can also be adjusted adaptively.

[0027] In implementation, in addition to the above-mentioned reset spring implementation, other implementation methods can also be used, such as setting an adaptive air cylinder to control the reset elasticity by adjusting the air pressure, or using other pneumatic structures.

[0028] As shown in the figure, limit components 11 and 12 are also arranged on the mounting plate 1. The limit component 11 cooperates with the connecting rod 84 to limit the angle of counterclockwise rotation of the front pressing wheel swing rod 81 by limiting the rotation angle of the connecting rod 84. The limit component 12 cooperates with the front pressing wheel swing rod 81 to limit the clockwise rotation angle of the front pressing wheel swing rod 81.

[0029] The mounting plate is a component part of the upper transverse structure of the sealing machine.

[0030] It should be noted that the sealing assembly has more than the above-mentioned embodiments, and the present application is also applicable to other implementation methods of the sealing assembly.
