Description

Technical Field

[0001] The utility model relates to the technical field of paperboard production, in particular to a paperboard production edge folding device. Background Art

[0002] The folding of cardboard production is an important link in cardboard processing. The main purpose is to ensure that the two sides of the cardboard are aligned during the continuous production process and to improve the quality and appearance of the cardboard. With the increase in the demand for corrugated cardboard, its production volume has gradually increased. On the production line of corrugated cardboard, multiple layers of paper are stacked to form thicker cardboard to meet the requirements of cardboard strength and toughness. After multiple layers of thin cardboard are stacked up and down, there is a phenomenon that the two sides along the width direction are not aligned, and it is easy to cause the top layer of paper and the bottom layer of paper to fall off the cardboard. Therefore, it is necessary to align the folding edges of the cardboard.

[0003] According to the publication number CN210792280U, a cardboard production folding device is disclosed, and the main points of its technical solution are: it includes a frame, a guide roller and a motor, the guide roller is rotatably carried on the frame, the output shaft of the motor is connected to the guide roller, and also includes a connecting plate and two limiting wheels; the length direction of the connecting plate is the same as that of the guide roller, and both ends of the connecting plate are provided with support plates, the support plates are fixedly arranged on the frame, the two ends of the connecting plate are respectively slidably matched with the two support plates, and an adjustment component is also arranged on the frame; the two limiting wheels are rotatably carried on the connecting plate, and the axes of the two limiting wheels are perpendicular to the horizontal plane, and the two limiting wheels are circumferentially provided with annular limiting grooves, and the two annular limiting grooves are used to respectively conflict with the opposite two sides of the cardboard. The above application can make the two sides of the cardboard automatically fold and align, thereby realizing the automation of the cardboard folding work and achieving the effect of reducing the labor intensity of the staff.
