[0017] Figure 4 It is another structural schematic diagram of the carton sealing machine of the utility model. Implementation

[0018] like Figure 1 As shown, the first embodiment of the present specification provides a carton sealing machine, which seals the packaging box by sticking tape on the surface of the packaging box. The carton sealing machine includes a mounting frame 1, two conveying members 2 for conveying the packaging box, two sets of swing rod assemblies 3 for adjusting the distance between the conveying members 2, and a movement 4 for sealing the box. The conveying member 2 can slide on the mounting frame 1.

[0019] In this embodiment, if Figure 1 and Figure 2 As shown, one end of one set of rocker assemblies 3 is connected to one of the conveying members 2, and the other end is located between the two conveying members 2 and connected to the mounting frame 1. One end of another set of rocker assemblies 3 is connected to another conveying member 2, and the other end is located between the two conveying members 2 and connected to the mounting frame 1. Each set of rocker assemblies 3 includes a first rocker 31 and a second rocker 32, and the first rocker 31 and the second rocker 32 are respectively located at the two ends of the conveying member 2. The first rocker 31 and the second rocker 32 drive the two ends of the conveying member 2 to move simultaneously, so that the conveying member 2 is not prone to skewing or deviation during movement.

[0020] In each set of swing bar assemblies 3, one end of the first swing bar 31 is rotatably connected to one of the conveying members 2, and the other end of the first swing bar 31 is located between the two conveying members 2 and is hinged to the mounting frame 1. One end of the second swing bar 32 is hinged to the mounting frame 1, and the other end of the second swing bar 32 is located between the two conveying members 2 and is rotatably connected to the conveying members 2. By rotating the first swing bar 31 or the second swing bar 32, the first swing bar 31 and the second swing bar 32 drive the conveying members 2 to slide on the mounting frame 1, and the distance between the two conveying members 2 changes, thereby adapting to packaging boxes of different widths.

[0021] like Figure 4 As shown, the box sealing device includes a first rotating shaft 51 and a second rotating shaft, wherein the first rotating shaft 51 is fixedly connected to the mounting frame 1 and is rotationally connected to the first swing rod 31. The second rotating shaft is fixedly connected to the mounting frame 1 and is rotationally connected to the second swing rod 32. By providing the first rotating shaft 51 and the second rotating shaft, the first swing rod 31 and the second swing rod 32 are rotationally connected to the mounting frame 1, respectively.

[0022] like Figure 1 and Figure 2As shown, the carton sealing machine includes two movements 4: an upper movement 4 and a lower movement 4, and the lower movement 4 is located between the two conveying members 2. The two movements 4 seal the upper and lower sides of the packaging box at the same time, with high packaging speed and efficiency. Of course, the present application does not limit the number of movements 4. In other embodiments, the number and position of the movements 4 can be set according to actual conditions and packaging requirements.

[0023] like Figure 3 As shown, the carton sealing machine includes two first transmission wheels 41 that enable the two groups of swing bar assemblies 3 to move synchronously. The two first transmission wheels 41 are rotatably mounted on the mounting frame 1 and are located between the two conveying members 2. The first transmission wheel 41 is provided with a first transmission wheel mounting hole 62, and the first swing bar 31 is provided with a first arc hole 61. The carton sealing machine may also include a first fixing member, which passes through the first transmission wheel mounting hole 62 and the first arc hole 61 to fix the first transmission wheel 41 to the first swing bar 31. In this embodiment, the first fixing member may be a bolt. By providing an arc hole on the first swing bar 31, the installation margin can be increased, thereby reducing the assembly error between the first transmission wheel 41 and the first swing bar 31.

[0024] In some embodiments, Figure 3 As shown, the first transmission wheel 41 is a gear, and the two first transmission wheels 41 mesh with each other. Through meshing, the two first transmission wheels 41 rotate in opposite directions. Through this arrangement, when one of the conveying members 2 moves, the first swing rod 31 drives the first transmission wheel 41 connected to the first swing rod 31 to rotate. Under the meshing action of the two first transmission wheels 41, the other first transmission wheel 41 rotates in the opposite direction to drive the other first swing rod 31 to rotate, and the other first swing rod 31 drives the other conveying member 2 to move, and the two conveying members 2 move in opposite directions along the width direction of the conveying member 2, and the two conveying members 2 move closer or farther away at the same time. In this embodiment, only one conveying member 2 needs to be adjusted to move the two conveying members 2 together, thereby saving manpower and improving work efficiency. Of course, in other embodiments, the first transmission wheel can be a sprocket wheel, and by arranging a chain on the two first transmission wheels, the two first transmission wheels can be realized to rotate synchronously in opposite directions. The present application does not limit the specific structure of the first transmission wheel, as long as the method of realizing the synchronous rotation of the two first transmission wheels in opposite directions can be used.

[0025] In actual operation, first, one of the swing rods 31 in one of the swing rod assemblies 3 is rotated, and the two conveying members 2 are simultaneously moved closer or farther away, thereby adapting to the width of the packaging box, and the two conveying members 2 clamp the packaging box. Then, the height of the movement 4 is adjusted so that the position of the movement 4 is adapted to the height of the packaging box. Finally, the conveyor belt of the conveying member 2 conveys the packaging box to complete the packaging and sealing of the packaging box.

[0026] like Figure 2As shown, in some embodiments, the carton sealing machine further includes two second transmission wheels 42 meshing with each other. The two second transmission wheels 42 are fixedly connected to the two second swing rods 32 respectively. The installation method is similar to that of the first transmission wheel 42. The carton sealing machine includes a second fixing member, the second transmission wheel 42 is provided with a second transmission wheel mounting hole, the second swing rod 32 is provided with a second arc hole, and the second fixing member passes through the second transmission wheel mounting hole and the second arc hole to fix the second transmission wheel 42 with the second swing rod 32. Through this arrangement, the two first swing rods 31 move synchronously through the two first transmission wheels 41, and the two second swing rods 32 move synchronously through the two second transmission wheels 42, thereby improving the rotation stability of the swing rod assembly 3.

[0027] In some embodiments, the first transmission wheel 41 and the second transmission wheel are both fan-shaped. Since the rotation range of the first swing rod 31 and the second swing rod is limited, the center angle of the transmission wheel does not need to be 360° to achieve the rotation of the first swing rod 31 and the second swing rod. Therefore, the transmission wheel is set to be fan-shaped, and the center angle of the transmission wheel is less than 360°, thereby saving materials and simplifying the structure.

[0028] like Figure 1 As shown, the carton sealing machine further includes a locking assembly installed on the swing rod 31 and the conveying member 2, and the locking assembly is used to lock the angle between the conveying member 2 and the swing rod 31, thereby locking the position of the conveying member 2. Specifically, the locking assembly includes a fastener 6, a conveying member mounting hole adapted to the fastener 6, and a swing rod mounting hole adapted to the fastener 6. The swing rod mounting hole corresponds to the position of the conveying member mounting hole, the conveying member mounting hole is provided on the conveying member 2, and the swing rod mounting hole is provided on the swing rod 31. The swing rod mounting hole is threadedly matched with the fastener 6. In this embodiment, when the conveying member 2 moves to a suitable position, the fastener 6 passes through the conveying member mounting hole and then threads with the swing rod mounting hole to fix the angle between the conveying member 2 and the swing rod 31, thereby locking the position of the conveying member 2. Of course, in other embodiments, the fastener 6 may also pass through the swing rod mounting hole and then threads with the conveying member mounting hole.
