Description

Technical Field

[0001] The utility model belongs to the technical field of rolling and flattening lunch box sheets, in particular to a rolling and flattening device for lunch box sheets. Background Art

[0002] Disposable fast food boxes have shifted from foam lunch boxes to environmentally friendly lunch boxes. The original foam lunch boxes have been eliminated because they are not resistant to high temperatures and the production process causes damage to the environment. They have been replaced by plastic lunch boxes, paper lunch boxes, and wooden lunch boxes. In order to prevent the thickness of the lunch boxes from being uneven or even perforated in the thin-walled parts, rolling and flattening the sheets before stamping the lunch boxes can improve the product quality of the lunch boxes.

[0003] For example, the patent number is CN201721531776.1, and the patent name is a roller flattening device for lunch box sheets, which includes a frame and a first flattening device arranged at one end above the frame. The flattening device composed of a hydraulic cylinder and a roller frame can squeeze the sheet evenly. The sheet used to produce the lunch box moves in the frame under the pulling force of an external winder. At this time, the hydraulic cylinder in the first flattening device controls the roller frame to roll and flatten the sheet for the first time, and then passes through the second flattening device to roll and flatten the sheet for the second time, so that the thickness of the sheet is uniform.

[0004] However, during the use of the above solution, the sheet moves in the frame under the pulling force of the external winder. If the placed sheet is long, the sheet may not be laid flat on the workbench, and the sheet may shake when being rolled and flattened, resulting in uneven rolling on both sides of the sheet. Utility Model Content

When it is necessary to enhance the flatness of the sheet laying, the rotating ring can be rotated to drive the rotating rod to rotate, and the rotating rod can drive the second roller pressing frame to rotate. The rotation of the second roller frame drives the second pressing roller to move, contacting and pressing down on the surface of the sheet to enhance the tension of the sheet so that it can be laid more flat on the workbench surface. Through the setting of the limit plate, the two sides of the sheet can be limited, thereby preventing the sheet from shaking and causing uneven rolling.
