Description

Technical Field

[0001] The utility model relates to the technical field of lunch box and meal cover packaging, in particular to a lunch box and meal cover conveying mechanism. Background Art

[0002] Disposable lunch boxes and lids are widely used in the food service industry due to their convenience. To improve production efficiency and reduce costs, manufacturers typically use automated production lines for large-scale production. On automated production lines, lunch boxes and lids are bagged after injection molding. To automate this process, a transfer mechanism is required between the packaging machine and the injection molding machine.

[0003] In some cases, lunch boxes and lids need to be rotated 90 degrees before packaging to match the packaging machine's requirements. A common solution is to install two perpendicular conveyor belts between the packaging machine and the injection molding machine to achieve this 90-degree rotation. However, when multiple lunch boxes or lids are stacked together, they are prone to tipping over during transfer between the two conveyor belts, impacting the subsequent packaging process.
