NRC-1100 A4 Paper Cutting and Packing Machine | Full Automatic Paper Processing Line
1. Product Overview
The NRC-1100 A4 Paper Cutting and Packing Machine is a fully integrated, high-efficiency industrial automated production line specially designed for paper manufacturers and large-scale paper converters. It realizes one-stop automatic processing from raw jumbo paper rolls to finished standard A4 copy paper reams, completely solving the manual cutting, counting and packaging problems of traditional paper processing equipment. This all-in-one production system integrates unwinding, slitting, precision shearing, automatic counting, ream wrapping and optional carton packing functions, realizing unmanned continuous production of A4 office paper.
Different from single-function paper cutting machines, this integrated production line adopts modular industrial design, with stable operation, ultra-high cutting precision and intelligent counting and packaging system. It is compatible with various types of paper raw materials including 70GSM, 80GSM and other common specification copy paper, writing paper and printing paper. Widely used in paper factories, printing and packaging enterprises, stationery production bases and other industrial scenarios, it is the core key equipment for large-scale standardized production of A4 paper.
2. Core Working Principle & Complete Production Process
The entire working flow of the NRC-1100 A4 paper cutting and packing machine is divided into two core stages: precision cutting stage and intelligent packing stage, with seamless connection between processes, no manual intervention in the whole process, and high production continuity and stability.
Stage 1: Precision Cutting Process (Jumbo Roll to Standard A4 Sheets)
This stage is the core link to ensure paper size accuracy, mainly completed by matched slitter-rewinder and high-speed sheeter equipment, which converts ultra-wide and super-heavy jumbo paper rolls into standard single A4 paper sheets. The original jumbo roll can reach a maximum raw material diameter of 1400mm with super large winding capacity, which effectively reduces the frequency of raw material replacement and improves production efficiency.
First, the jumbo paper roll is stably mounted on the automatic unwinding rack, and the servo feeding system controls uniform and stable paper feeding to avoid paper deviation and tension breakage. Then, the paper passes through high-hardness circular alloy cutting knives for precision slitting, and the system accurately sets the slitting width to 297mm according to the A4 paper standard width, cutting the wide roll paper into multiple narrow roll paper strips of equal width. Finally, the narrow roll paper enters the high-speed sheeter, and the rotary high-speed cutting tool performs fixed-length cutting according to the A4 standard length of 210mm.
The whole cutting process supports adjustable speed from 20 to 150 times per minute, with horizontal cutting precision controlled within ±0.2mm. The ultra-high precision processing effectively avoids paper edge burrs, size deviation and uneven cutting, ensuring that the finished A4 paper can adapt to all kinds of printers, copiers and printing equipment without jamming, wrinkling and other problems, meeting industrial-grade paper production standards.
Stage 2: Automatic Packing Process (Sheet Finishing to Finished Products)
After the A4 paper sheets are cut and formed, the equipment automatically completes sorting, counting, wrapping and box packing, realizing finished product output. Firstly, the optical intelligent counting sensor and mechanical calibration system work synchronously to accurately sort scattered paper sheets and count them into standard 500-sheet reams, eliminating the error of manual counting and ensuring the consistency of each finished product specification.
Then the automatic wrapping mechanism starts to work, using high-quality protective paper or plastic film to fully wrap the paper reams. The equipment adopts dual sealing modes of hot melting and glue sealing, which makes the wrapping tight and firm, effectively preventing paper from moisture, dust and scratch during storage and transportation. Meanwhile, the built-in intelligent labeling system can automatically print and paste product information labels such as paper gram weight, specification, production date and batch number to realize standardized product identification.
In addition, the equipment supports optional automatic case packing function. The system can automatically group 5-10 standard paper reams according to customer settings, accurately place them into customized cartons, and complete automatic box sealing and shaping, which is convenient for centralized transportation and market distribution, greatly improving the overall packaging efficiency of the production line.
