This papermaking machine boasts versatility in raw material utilization, accommodating a range including waste paper, recycled paper, wood, bamboo, reed, wheat straw, cotton, and bagasse. It yields premium-grade craft paper, kraft paper, corrugated paper, fluting paper, testliner paper, among others, with a daily output capacity of approximately 200 tons.
Raw Material Preparation: The process begins with the preparation of raw materials, including recycled paper, wood pulp, and other additives such as starch and adhesive. These materials are carefully selected and processed to meet the specific requirements for corrugated paper production.
Pulping: The selected raw materials are pulped using mechanical or chemical methods to break down the fibers and create a slurry-like mixture known as pulp. This pulp is then refined and screened to remove impurities and ensure uniformity.
Corrugating: The pulp is then fed into the corrugating machine, where it is formed into two separate layers: the linerboard and the corrugating medium. The linerboard consists of flat sheets of paper, while the corrugating medium is formed into a series of parallel ridges and valleys to create the characteristic wavy pattern of corrugated paper.
Gluing: Once the linerboard and corrugating medium are formed, they are joined together using adhesive, typically starch-based glue. The adhesive is applied evenly to the corrugating medium, and the linerboard is pressed against it to create a strong bond.
Heating and Drying: After the layers are glued together, the combined sheets pass through heated rollers or drying cylinders to remove excess moisture and cure the adhesive. This process ensures that the corrugated paper achieves the desired strength and stiffness.
Cutting and Stacking: Once the corrugated paper is fully formed and dried, it is cut to the desired size and shape using precision cutting equipment. The finished sheets are then stacked and prepared for packaging or further processing.
Quality Control: Throughout the production process, stringent quality control measures are implemented to monitor the thickness, strength, and other properties of the corrugated paper. Any defects or inconsistencies are identified and corrected to ensure that the final product meets the required standards.
