NRC MACHINE: Full Automatic A4 Copy Paper Machine and Production Line
Introduction
In the modern office and printing industry, A4 copy paper is an indispensable consumable, with its standardized size (210mm × 297mm) widely adopted globally as specified by ISO 216. To meet the massive and high-efficiency demand for A4 copy paper production, NRC MACHINE has developed a full automatic A4 copy paper machine and integrated production line, which integrates advanced technology, stable performance and intelligent operation.
This equipment not only realizes the full automation of A4 copy paper production from raw material processing to finished product output, but also highlights excellent performance in the core links of A4 paper cutting and packaging, providing reliable and efficient production solutions for paper processing enterprises around the world.
Overview of NRC MACHINE Full Automatic A4 Copy Paper Production Line
NRC MACHINE’s full automatic A4 copy paper production line is a integrated system designed for large-scale, high-precision and efficient A4 copy paper manufacturing. Different from traditional semi-automatic equipment, this production line covers all links of A4 copy paper production, including raw material unwinding, tension control, longitudinal and transverse cutting, paper sorting, counting, stacking, packaging and finished product discharging.
The entire line adopts PLC intelligent control system and AC frequency conversion stepless speed regulation technology, which ensures the coordination and stability of each link, greatly reduces manual intervention, improves production efficiency, and guarantees the consistency and quality of finished A4 copy paper.
The production line is equipped with high-quality accessories and advanced control components, with strong durability and adaptability. It can process raw paper rolls with a width of 846mm (net cutting width 840mm) and a diameter of 400-1200mm, suitable for paper with a grammage of 60-100gsm, which is the standard grammage range of A4 copy paper.
The maximum design speed of paper running can reach 250-350m/min, and the ream discharging speed is 6-8 reams per minute, realizing large-scale mass production while ensuring product quality. In addition, the production line has a compact structure, with an overall dimension of 13m × 2.75m × 2.1m (main body), which saves factory space and is convenient for installation and maintenance.
Core Functions: A4 Paper Cutting and Packaging
3.1 A4 Paper Cutting Function
The cutting link is the core of A4 copy paper production, and the precision and efficiency of cutting directly determine the quality of finished products.
NRC MACHINE’s full automatic A4 copy paper machine is equipped with a high-precision double-blade cutting system, which integrates five sets of longitudinal cutting knife groups and one set of simultaneous cross-cutting knife groups, realizing precise cutting of raw paper into standard A4 size.
The cutting system adopts advanced tension control technology (four sets of tension control systems) and anti-warping mechanisms (four sets), which effectively avoids paper deviation, wrinkling and edge burrs during the cutting process.
The cutting accuracy can reach ±0.2mm, which fully meets the international standard of A4 copy paper size error, ensuring that each sheet of A4 paper has consistent size, flat edges and no burrs, which is conducive to smooth use in printers, copiers and other equipment.
In addition, the machine is equipped with a waste paper automatic discharging system, which can timely discharge the waste edges generated during cutting, ensuring the cleanliness of the production line and reducing material waste.
The cutting process is fully automatic, and the operator only needs to set the cutting size (standard A4 size is preset, and can be adjusted according to special needs) and production parameters through the touch screen, and the machine can complete the cutting work continuously and stably.
The equipment also has a PLC error alarm and shutdown system, which can timely alarm and stop operation when there is a cutting error, avoiding the waste of raw materials and ensuring production safety.
3.2 A4 Paper Packaging Function
After cutting, the A4 paper needs to be sorted, counted, stacked and packaged to form finished reams (usually 500 sheets per ream), which is convenient for storage, transportation and sales.
NRC MACHINE’s full automatic A4 copy paper machine is equipped with an integrated automatic packaging unit, which connects seamlessly with the cutting link, realizing the automatic transition from cut paper to finished packaged reams.
The packaging unit includes a paper sorting system, a PLC counting device, a stacking system and a wrapping system. The cut A4 paper is sorted neatly by the 2D oscillation sorting system, and then counted accurately by the PLC counting device (counting range 0-500 pieces per ream), ensuring that each ream of paper has a consistent number of sheets.
The stacked paper reams are lifted by the screw rod lifting device and transported to the wrapping system, where they are wrapped with wrapping paper (size 550-560 × 386mm) automatically. The packaging unit has a motor power of 6.5kw and a gluing power of 2.25kw, adopting compressed air (0.6-0.8mpa) for gluing and shaping, ensuring that the packaging is firm, flat and beautiful, and effectively preventing the paper from being damp, contaminated or damaged during transportation.
The packaging process is also fully automatic, with adjustable packaging speed (synchronized with the ream discharging speed of 6-8 reams per minute), which can be matched with the production efficiency of the cutting link, realizing the continuous and efficient operation of cutting and packaging.
