Description

Technical Field

[0001] The utility model relates to the field of carton production equipment, in particular to a cardboard spray humidifying device. Background Art

[0002] During the carton production process, the cardboard is first die-cut, then the die-cut cardboard is rolled by a creasing machine to form indentations, and finally the cardboard is folded into shape. In order to ensure the production quality of the carton, the cardboard is usually moistened before die-cutting to increase its toughness. This can prevent the cardboard from cracking or warping during die-cutting or rolling due to drying, thereby preventing an increase in the scrap rate.

[0003] Currently, a humidifier is commonly used to increase the wetness of the cardboard surface. The humidifier includes multiple atomizing nozzles installed side by side. When the cardboard is conveyed under the humidifier, the atomizing nozzle atomizes water and sprays it onto the cardboard surface to humidify the cardboard. However, the atomizing nozzle can only humidify the upper side of the cardboard and cannot humidify the lower side of the cardboard, resulting in uneven humidification and reduced humidification effect, which in turn affects the quality of cardboard production. In addition, the water mist can easily be blown into the die-cutting equipment or creasing equipment in the next process, causing rust or corrosion of the metal parts of the equipment, damaging the surface and internal mechanical structure of the equipment, and causing moisture or short circuit of electronic components, causing electrical failure of the equipment or damaging the circuit board, shortening the service life of the equipment.
