Cardboard is a packaging material for cardboard boxes, boxes, gift boxes, and stationery products, with a wide range of applications. Its production method is to composite two or more layers of roll paper.

For the convenience of production and improvement of work efficiency, the raw materials of cardboard have larger specifications and sizes. After the cardboard composite is completed, longitudinal and transverse cutting are carried out in sequence to shorten the packaging specifications and facilitate transportation. Specifically, the hard board is first cut into multiple pieces of hard cardboard by a longitudinal cutting mechanism, forming a longitudinal section on its side, and then cut into multiple sections of hard cardboard by a transverse cutting mechanism, forming a transverse section at its front and rear ends. In the above production process, the right angle between the longitudinal and transverse sections will cause delamination due to high-temperature drying, greatly affecting the quality of the cardboard.
Provide a structurally simple anti delamination cardboard composite production line.

Hardboard production line for anti delamination hard cardboard, comprising a conveying mechanism, a bonding mechanism, a compaction mechanism, a drying mechanism, a cooling mechanism, a longitudinal cutting mechanism, a transverse cutting mechanism, a winding mechanism, and a control system; A spray mechanism is installed between the longitudinal cutting mechanism and the horizontal mechanism, and the spray mechanism spans over the cardboard.

The spray mechanism includes several nozzles, a cross bar and two support bars. The two support bars are used to support the cross bar, the nozzles are evenly distributed on the cross bar, and the support bars are lifting.

The spray mechanism also includes two guide pillars and air cylinders, two support rods are connected to the corresponding guide pillars by sliding rails, and the movable end of the air cylinder is connected to the cross bar.

The nozzle of the spray mechanism is a high-pressure atomizing nozzle.

The spray mechanism also includes a humidity sensor and a temperature sensor, which are connected with the control center of the spray mechanism.

The spray mechanism is connected with the control system.

A spray mechanism is added between the cross cutting mechanism and the longitudinal cutting mechanism to realize rapid cooling, improve the humidity of the cardboard, effectively avoid the layering of the cardboard, and ensure the product quality, especially in dry summer or winter. The utility model also adopts the lifting design of the spray mechanism, and realizes the adjustment of the spray range and humidity by changing the height, which is conducive to adapting to a variety of production environments and improving efficiency. At the same time, humidity sensor and temperature sensor are also added to realize intelligent automatic adjustment of spray state, reducing workers’ skill requirements.
