The hard paperboard production line is a specialized equipment for producing corrugated cardboard. Mainly composed of raw paper racks, paper feeding carts, preheating (corrugated paper, inner paper, intermediate paper), paper receiving machines, single sided corrugated machines (vacuum adsorption negative pressure, clamp type, air cushion type positive pressure), conveying overpasses, overpass suction, multiple heat cylinders, sizing machines, double-sided machines, (computer) longitudinal cutting machines, (computer spiral, straight knife) transverse cutting machines, horizontal conveyors, horizontal discharge stacking machines, (automatic sorting, counting) stacking machines, and steam heating systems The main equipment consists of air compression system, rubber making system, electrical control system, steam recovery system, etc.

A complete corrugated cardboard production line should include single machines and systems for all processes of producing corrugated cardboard. It can also be simplified or added according to user needs, such as special equipment such as printing patterns and trademark patterns (pre printing), gluing, coating, and moisture-proof.

Two or more layers of paper can be called cardboard when they are glued together. Two layers of cardboard generally consist of one layer of pit paper and one layer of inner paper, which is called pit cardboard. It only needs to be equipped with a single sided corrugated machine, one or two paper racks, and a vertical and horizontal cutting and conveying integrated machine (double knife, E-pit, and throwing knife machine).

Three layer cardboard is generally composed of one layer of inner paper, one layer of surface paper, and one layer of corrugated paper. The assembly of corrugated cardboard production equipment with three or more layers together is called a corrugated cardboard production line.

5、 Seven layer hard paper board production line and so on.

False seventh floor, false ninth floor.

Four layer and six layer cardboard, also known as pit paper (face paper).

The design speed of the corrugated cardboard production line ranges from 60 to 250mm/min, and the effective width of the paper ranges from 1400 to 2500mm. The corrugated type is generally UV shaped, with several types such as A, C, BC, B, E, and F. According to market demand, the corrugated cardboard production enterprise determines the height and number of corrugations.

The corrugated cardboard production line is a high-speed and efficient production process that involves pressing corrugated rolls of raw paper, gluing and drying, cooling and shaping, slitting, creasing, and transverse cutting into standard cardboard. Finally, qualified cardboard products are produced through processes such as transportation and stacking, achieving high-speed and efficient flow operations.
