Description of the Four-Group Synchronous Belt Drive Structure in the Corner Side Carton Sealer
2025-11-27
In the conveying system of the corner side carton sealer, the upper and lower four-group synchronous belt drive is one of the key structural components. This structure is composed of two pairs of independent belt units positioned above and below the carton. Through synchronous driving, the belts provide a wrapped clamping effect, generating a stable and continuous conveying force once the carton enters the machine. This allows the carton to move smoothly regardless of variations in weight, material, or minor deformation.
The synchronized upper and lower belts distribute pressure evenly, preventing carton deviation or vibration caused by insufficient force on one side. While being held by the four belts, the carton is guided to maintain a centered movement path, ensuring better alignment when entering the sealing area. For corner-side sealing processes, the stability of the carton’s position directly affects the accuracy and consistency of the sealing lines.
This structure also offers stronger adaptability when handling cartons of different sizes and strengths. Because the four belts deliver a symmetrical driving force, the system can stabilize and correct cartons with uneven wall thickness, slight collapse, or imperfect corners during conveying. This reduces occurrences such as carton jamming or sudden stops.
From a maintenance perspective, the synchronous belt system features a simple and clearly visible operating layout. Maintenance personnel can easily observe belt tension and wear conditions. The upper and lower belt groups adopt a modular installation design, allowing individual disassembly and replacement, ensuring stable conveying performance during long-term operation.
