[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention. Example 1

[0034] Reference Figures 1 to 6 As shown, the present invention discloses a box sealing device for sealing a box body, thereby enabling the integration and batch storage of products for subsequent shipment or other processes. The box body includes but is not limited to a cardboard box.

[0035] The box sealing device includes a workbench, which includes a base 10, a support body 11 and a side panel assembly 12. The support body 11 is fixedly installed on the base 11, and the side panel assemblies 12 are located on both sides of the support body 11. In addition, the side panel assemblies 12 are slidably arranged on the base 10. The support body 11 and the side panel assemblies 12 cooperate with each other to form a space-adjustable receiving space, and the box body can be received in the receiving space.

[0036] It should be noted that the side panel assembly 12 is extended along a first direction, and the side panel assembly 12 can be driven to move along a second direction to adjust the spacing of the side panel assembly 12, and the second direction is perpendicular to the first direction.

[0037] The box sealing device further includes a movable module 2 , which is extended along the first direction. A movable end of the movable module 2 is connected to the workbench to drive the workbench to move along the first direction.

[0038] The carton sealing device further comprises a carton sealing unit, which comprises a lifting drive 30, a mounting frame 31, a lever assembly, a flattening assembly and a packaging assembly. The lifting drive 30 is used to drive the mounting frame 31 to move in a height direction.

[0039] The lever assembly, the flattening assembly and the packaging assembly are sequentially arranged on the mounting frame 31 along the first direction. The lever assembly can close the flip cover of the box, the flattening assembly can flatten the flip cover, and the packaging assembly is used to fix the flip cover, thereby completing the packaging of the box.

[0040] During operation, the workbench is driven by the moving module 2 to sequentially pass through the lever assembly, the flattening assembly, and the tape application assembly.

[0041] The box sealing device further includes a control unit, which is electrically connected to the moving module 2 and the box sealing unit to control the movement of the moving module 2 and can cooperate with the box sealing unit to seal the box body.

[0042] It can be seen from this that the present invention is intended to protect a carton sealing device, which is provided with a workbench, a moving module, a carton sealing unit, and a control unit. The workbench includes a base, a support body, and a side panel assembly. The carton to be sealed is placed on the support body. By adjusting the spacing of the side panel assemblies, the side panel assemblies and the carton can be fitted together, thereby forming a receiving space adapted to the size of the carton, effectively avoiding the position deviation of the carton during the sealing process, and playing a better positioning role. The workbench is driven to move along the first direction by the moving module, thereby sequentially passing through the lever assembly, the flattening assembly, and the adhesive tape assembly to press down, flatten, and seal the flap of the carton. The carton sealing device of the present invention has a simple overall structure, is easy to maintain, is compatible with cartons of various sizes and models, and has high versatility. At the same time, during the carton sealing operation, it can effectively avoid the carton from tilting or tipping over, ensuring the accuracy of the carton sealing position, without the need for operators to intervene to adjust the carton position, thereby effectively improving the packaging quality and ensuring the consistency of the packaging. In addition, the carton sealing device of the present invention has a high degree of automation and can cooperate with other equipment on the production line, thereby effectively improving production efficiency.
